factory reset

yea, the new un-carrier is becoming (surprise) another carrier.

try a factory reset from the settings menu.

I wiped everything, including the SD. Cleaned my mess up ....... so far.

Batt drains way slower, charges way faster, even from my Mac. And is in general pretty stable. Calls have been fine even in NYC where T-Mo def doesn't have enough bandwidth.

T-Mobile is a little bit wild west.

There is still some dumb stuff, but I think that may be LGs implementation of Lolli 5.1.

So far, I'm not using their Launcher (Apex) or lock screen (Next) and even that has caused no issues.

It's still a beast in my pocket. I really wanted to get the M9, but the deal was too good and HTC is having fiscal issues.

Where is the City of Beer? Milwaukee, Asheville, Boston, Paris?
[T-Mobile LG G4] thevmax:
I couldn't do a wipe because the system failed during a re-flash and left me with a 10n bootloader and a 10h system file. I had previously moved up to Micromod777's xtreme 2.0 which is h81110n. I had some problems with ads and extraneous apps on my phone. I did not think it through far enough when I reflashed with stock h81110h.

The phone was hard bricked and I had to send it back to LG. Here's hoping they just reflash it and send it on it's way back...

From my point of view: the City of Beer is Milwaukee, and it's not just because I live here.

A number of years ago, I went to Hooligan's and joined the "Around the World in 80 Beers" Club. There are a number of clubs like this in Milwaukee.

Finished drinking up the 80 beers in about a month. Got a t-shirt and my name on the wall. Plus, I actually learned about beers from other countries. For me, German Weiss Beer is the grand finale.
[T-Mobile LG G4] metropical:
I'm a Belgian fan. Use to drink german in my ut. And many American crafts. Asheville has lots of craft brewing going on, if you ever get there.

Hope LG flash and return.

Lg g4 restored back from limbo

09/12/2015 : I had an email from LG that says my phone was fixed and is on it's way back to me.

Estimated Delivery via Fedex is Tuesday, 09/15/2015 and NO CHARGE!

I am :D about this.

However, there is a BIG DISCONNECT between what I know was done to the phone and what

the RA ticket shows: "Defect: Power-Completely off", <--- not what I said or what was wrong AND

"Repair Results: Power Management IC(PMIC)" <---this I believe, they probably shorted the proper leads

and that restored the IC(PMIC) and then reflashed the factory ROM. Fact is the unit was ON with no screen

functions available.
[T-Mobile LG G4] metropical:
sounds good. Hope it's vastly better
[T-Mobile LG G4] Sfkn2:
I also had the REG99 error, so I called TMO and they re-submitted my issue to engineers twice. My phone stopped getting REG99 as much, but now I see an ER81 error. Granted, I got nothing but wifi calling errors when I was on the GoGo inflight text with Alaska Air just last week.
[T-Mobile LG G4] jamesd1085:
Xposed installed?
[T-Mobile LG G4] Sfkn2:
No sir :)
[T-Mobile LG G4] jamesd1085:
Just checking...xposed breaks wifi calling on 10n and we have posted the issue to rovo89 github in hopes he can fix it...good luck
[T-Mobile LG G4] Jammol:
Just so you guys know, it's not an LG issue. My Note 4 has similar issues. For me the REG99 error is only when I'm connected to unprotected WiFi networks that are slow. Also VoLTE is causing me major issues with Comcast Xfinity. Whenever it's on, I get super slow internet speeds for anything Google related. Once I turn VoLTE off, WiFi calling works, and no more slow Google related apps or web browsing.

To the OP what is your current internet provider?
[T-Mobile LG G4] siraltus:
Is your WiFi Calling staying connected after updating to 10n? Mine was working fine on 10h, but on 10n it disconnects after 5-10 minutes with a REG99: Unable to connect error and won't reconnect until I reboot the phone.

I did all the troubleshooting steps with T-Force: factory reset, got a new SIM card, got an update sent to the SIM card twice, factory reset again, and no dice.

Is anyone else experiencing this on 10n? I'm on stock rooted 10n (odex).

EDIT: It's XPosed. As long as the XPosed Framework is installed (even with no modules), WiFi Calling is completely broken.
[T-Mobile LG G4] gerald410:
I was getting the same error on 10N. I called and was transferred to Tech Support. They updated my E-911 info and was back up in running in less than 5 minutes
[T-Mobile LG G4] jamesd1085:
Are you using xposed? I am experiencing same while xposed is installed and it works perfect without...
[T-Mobile LG G4] gerald410:
I'm using xposed and it works great (wi-fi calling).
[T-Mobile LG G4] jamesd1085:
Not the case for me and others are trickling in with the same issue
[T-Mobile LG G4] Synchronicities:
So I rooted my phone a little more than a week ago and then flashed MicroMod777's rooted stock 10n ROM a few days later. Up until this point, WiFi calling was working. I then flashed the Xposed framework v72, downloaded some modules, and installed them. I realized that WiFi calling was no longer available and would give me the classic REG99 error, unable to connect. Another user on MicroMod777's 10n stock ROM thread (http://xdaforums.com/tmobile-g4/development/rom-g4-h811-10n-stock-rooted-rom-t3188858/page9) had the same problem, though another user responded that Wifi calling was working fine with the 10 ROM and Xposed v72.

I uninstalled Xposed and I could immediately access WiFi calling, so it seems that Xposed is conflicting with the 10n stock ROM's WiFi calling. Same results with v73. Users who are getting WiFi calling to work on Xposed, did you get the official 10n update OTA or flash a rooted ROM? And what version of Xposed are you running?
[T-Mobile LG G4] gerald410:
Stocked rooted rom and v72 I believe (how to confirm?).
[T-Mobile LG G4] siraltus:
Open the XPosed Installer app and look in the Framework section.
[T-Mobile LG G4] siraltus:
I was having the issue on a totally stock, factory-reset phone with nothing installed.

T-Force opened a ticket with network engineering, supposed to be resolved by tomorrow.
[T-Mobile LG G4] jamesd1085:
Just asking as i have same issue but only with xposed...as are some others
[T-Mobile LG G4] siraltus:
Interesting.... I wonder why. I have Xposed installed on my Note 4 also and WiFi Calling works perfectly fine there. Might be a specific module causing it.

Come to think of it, when I factory-reset the phone, Xposed was still installed into the system partition, since it's not an app, but a modification to system files.

I will have to re-test after explicitly uninstalling Xposed. It would be a total bummer if Xposed is the problem. And if it is, I hope it's just a specific module that I can disable. I'd hate to lose YouTube AdAway and a few others.
[T-Mobile LG G4] jamesd1085:
Mine is broken without even adding modules...fixes instantly after flashing xposed uninstaller
[T-Mobile LG G4] siraltus:
Well that just sucks. I just uninstalled Xposed and WiFi Calling is staying connected now. This is not good.
[T-Mobile LG G4] jamesd1085:
Looks like we need to try and get some logs for rovo and hopefully he can easily fix it...

Scrap that! Download SELinux mode changer and change to permissive...instantly popped up and stayed connected! Great news
[T-Mobile LG G4] siraltus:
O RLY... is that an Xposed module?
[T-Mobile LG G4] jamesd1085:
Try ticking disable resource hooks in exposed installer app...and You can google SELinux mode changer its an app it coonects after boot...takes longer than it used to but its working on my end
[T-Mobile LG G4] gerald410:
I'm running v71 thx.
[T-Mobile LG G4] siraltus:
Nope, neither works. WiFi Calling is still busted while Xposed is installed.
[T-Mobile LG G4] jamesd1085:
Try unticking disable hooks...it's working fine without that...try a couple reboots...mine has settled in and works fine...also did you opeen the app and grant root and press permissive?
[T-Mobile LG G4] siraltus:
Of course I granted root and pressed Permissive, I know what SELinux is. I also unticked that checkbox and rebooted like 5 times. It either never connects or connects and disconnects after 2-3 minutes.
[T-Mobile LG G4] jamesd1085:
Weird...mine has been steady for 20 mins and have had outgoing and incoming call and received calls after i turned screen off...good luck...if i find any other info i will get back to you
[T-Mobile LG G4] siraltus:
So let me get this straight. You:

1. Installed SELinux Mode Changer, set it to Permissive.

2. Unticked "Use Resource Hooks."

3. Rebooted.

Correct? Or did it start working after JUST setting SE Linux Mode Changer to Permissive and rebooting?

Also, how long did you have to wait for it to connect and stay connected? Thanks for the info!
[T-Mobile LG G4] jamesd1085:
Just the SELinux mode changer...also it doesn't like reboots so try a full powerdown...after i rebooted it stopped working but after turning it completely off all is great again
[T-Mobile LG G4] siraltus:
Oh, maybe that's why, I rebooted, didn't power-down.... let me try again.
[T-Mobile LG G4] siraltus:
I did all this in this exact order and it it still doesn't work. It connects for a minute or two, the disconnects and it's stuck on Enabling. Uninstalling Xposed fixes it instantly.
[T-Mobile LG G4] Synchronicities:
I was able to get WiFi calling working with Xposed framework, but only with v71. I tried v72 and v73 and neither of those worked. I am currently running MicroMod777's xTreme ROM v2, based on the 10n update. I connected almost immediately to my home network and was able to make a 5-min call, no problems whatsoever there.
[T-Mobile LG G4] gerald410:
Exactly!
[T-Mobile LG G4] siraltus:
Not working with v71 here either, same symptoms. It connects for a minute then disconnects and it's stuck on Enabling, eventually errors out with REG99: Unable to connect. I'm on stock rooted 10n (odex). I wonder what makes MicroMod's ROM different.

Hey [MENTION=2522637]MicroMod777[/MENTION], could you chime in with what's different in your ROM vs stock rooted 10n? Maybe we can figure out what causes Xposed to break WiFi Calling on stock but not on your ROM...
[T-Mobile LG G4] siraltus:
Yeah, even with Xposed installed, if I made a call, it stayed connected even for an hour, but as soon as I hung up, it would disconnect and error out with REG99.
[T-Mobile LG G4] raw2000j:
Anyone know how to uninstall xposed my wifi calling not working

---------- Post added at 11:20 PM ---------- Previous post was at 10:44 PM ----------

I tried 71 72 73 none worked uninstalled xposed wifi calling working again
[T-Mobile LG G4] siraltus:
Flash the correct uninstaller (arm64) from the Xposed thread: http://xdaforums.com/showthread.php?t=3034811
[T-Mobile LG G4] wolf5150:
I too find that just having the framework installed is enough to confuse tMo's wifi calling to the point that it is absolutely useless
[T-Mobile LG G4] Swizzle82:
I'm running 10N with xposed 73. I get the error message every now and then, but it does work. I just attributed to the fact that I recently moved and the wifi sgnal is shoddy.. I'll keep a closer eye on it.

---------- Post added at 10:11 PM ---------- Previous post was at 10:08 PM ----------

Also wanted to add that wifi calling had issues after the G3 updated to lollipop..
[T-Mobile LG G4] MicroMod777:
TMO apps, and Google apps have been removed. Main different, plus is SE Linux enabled, with busybox.
[T-Mobile LG G4] DRSdroid:
Is there anyway we can enable init.d scripts and perhaps create a script to set SELinux to permissive at boot? Or any ROM chefs know a way to do it via flashable zip or baked into a rom?
[T-Mobile LG G4] siraltus:
I tried switching SELinux to Permissive via terminal (do setenforce 0 as root) and nada. Same with doing it via an init.d script with Universal init.d (and yes, getenforce returns Permissive, so I know changing SELinux mode works).

I think WiFi Calling hates some modification that Xposed does, we just need to figure out which one. I wonder if rovo89 could help? I know he's super-busy, but he's the only one who could shed some light on it. Or maybe romracer or arter97 who have also worked on customized variants of Xposed.
[T-Mobile LG G4] jamesd1085:
I got a dmesg and kmesg log to rovo and told him the issues we were having and there was some serious errors showing up...now we hope and wait
[T-Mobile LG G4] siraltus:
Thank you for doing this! Could you send me the logs, too? I'd like to take a look at those errors.
[T-Mobile LG G4] Swizzle82:
Just so you guys know.. I just got a new G4 and updated it to 10N no root yet no xposed and I still sometimes get wifi calling error.. Not xposed related. Call tmobile and have them update your wifi calling address and you should be good.. Should be.
[T-Mobile LG G4] jamesd1085:
Its xposed...it's 100% not working while installed...believe me i tried everything and to [MENTION=2317284]siraltus[/MENTION] the logs are posted in the xposed q and a forum
[T-Mobile LG G4] Swizzle82:
Well when I had xposed on my other G4 running10N I got the exact same issue.. Sometimes worked sometimes error..
[T-Mobile LG G4] siraltus:
Dude, read the original post. We already called support, got new SIM cards, got updates sent to our SIM cards, and factory-reset our phones. Your advice does not apply to our problem.
[T-Mobile LG G4] Swizzle82:
Except it's not completely broken on mine..
[T-Mobile LG G4] DRSdroid:
It may not be the same problem for everyone, but it is for the majority of us.

On 10n with No xposed, 99% reliable wifi calling. Install exposed on 10n, no wifi calling at all. Not after reboot, not after forgetting network and reconnecting, not after clearing cache.. Uninstall xposed, wifi calling back to 99% reliable.

Not sure why that's different for some people, but for the vast majority of us it seems to be those symptoms.
[T-Mobile LG G4] siraltus:
It's intermittent on mine. It repeatedly connects for 5-10 minutes and disconnects. If I make a call, it stays connected until I hang up. It's definitely broken here, and this is on a factory-reset phone with only root and Xposed installed, nothing else.
[T-Mobile LG G4] siraltus:
Tested on Xposed v74, still broken.
[T-Mobile LG G4] axel06:
Can somebody explain to me why my wifi calling with xposed installed is working when I am getting a 3+ bar data reception, but not when no T-Mobile data?
[T-Mobile LG G4] romracer:
The absolute best way to draw attention to issues is to post a detailed issue on GitHub, not to PM myself or [MENTION=4419114]rovo89[/MENTION]. I reviewed all the issues for the various Xposed components and saw no issue reported for this.

I would strongly suggest someone who is capable and willing to test should create an issue here. Remember, at the minimum a full logcat will be needed, and preferably one captured while the error occurs.
[T-Mobile LG G4] jamesd1085:
Thank you i submitted the issue and posted logs but they are in the comments because it wouldn't allow me to paste links in my original post...anyone else with this issue please post logs as well so we have a better chance to give a log that shows the actual issue
[T-Mobile LG G4] siraltus:
How do I gather those logs on my phone?
[T-Mobile LG G4] jamesd1085:
Kernel audiutor has both logcat and driver log under the settings menu...just wait till the wifi calling fails to work and take a logcat and if you want a driver log as it may catch something...i then uploaded them to my box account and posted links to the logs
[T-Mobile LG G4] siraltus:
Thanks! The logcat and dmesg are attached to this post for anyone who wants to view them (taken right after I got the REG99: Unable to Connect error), plus I added them to the issue in GitHub.
[T-Mobile LG G4] siraltus:
People over on the unofficial Xposed for Samsung thread are reporting they're losing WiFi Calling on devices running 5.1.1: http://xdaforums.com/showpost.php?p=62747570&postcount=2801

EDIT: Apparently it was because Wanam Xposed removed a line from feature.xml that enabled the Sprint WiFi Calling CSC feature. Not related to our problem.
[T-Mobile LG G4] axel06:
Their WiFi calling problem is apparently related to module "wanam": "You are right. Just checked my features.xml and it was replaced even after uninstalling wanam. Just deleted and renamed old one and wifi calling is back."

On LG G4 it even stops WITHOUT any modules installed yet!!
[T-Mobile LG G4] siraltus:
You're right. I removed the post about their problem from our GitHub issue.

Wifi Calling t-mobile

A member from "Team Bliss":

"T-Mobile released some source for it and it can be built into rom now. ...."
[T-Mobile LG G4] jamesd1085:
About damn time...i don't run aosp roms just because wifi calling doesn't work...good to hear
[T-Mobile LG G4] axel06:
Now we need to convince [MENTION=2522637]MicroMod777[/MENTION] applying it to his rom ! Please!
[T-Mobile LG G4] jamesd1085:
Its already there...xposed breaks it on 10n...we need rovo89 to see if its a fixable issue or not from the logs we posted to github issue but he's very busy atm...idk if We will soon see it fixed...i no longer need it though as i used xposed only for battery life and to theme battery icon...battery life is fine without and i now use the 3minit battery icon mod and all im missing is a custom kernel and when that comes i will be 100% satisfied with my g4
[T-Mobile LG G4] axel06:
"T-Mobile released some source for it and it can be built into 10N customs roms now.

10N is fixable, that's what I just said!! Others use more of the Xposed features than you. So, let's think of the rest of the hobbyists...like Gravity, etc. ....

We would not need rovo89 because he already has Xposed for Lollipop 5.1 - it is now up to our expert dev MicroMod777 to incorporate the T-Mobile source code into this rom here to fix Xposed conflict with wifi calling - right, MicroMod777 ?
[T-Mobile LG G4] jamesd1085:
What I'm trying to explain is that its the same code that's already built in...xposed interferes with it... I'm not saying its impossible to fix using this code but it's more likely that compatibility will have to be worked out on xposed side.
[T-Mobile LG G4] axel06:
You might be right - I believe our dev can solve it. At least that's what Team Bliss is telling me. THEY now are able applying it to rom that they are working on (CM12.1 for H811). Who knows...hopefully our dev will respond!
[T-Mobile LG G4] siraltus:
Rovo89 needs to investigate this so that people who run the stock ROM can use WiFi Calling.

I don't want to run MicroMod777's ROM, as I like to stay as close to stock as possible.

It might be a symptom of a bigger problem that might break other things on other devices, so it needs to be investigated and fixed at its source - in Xposed.
[T-Mobile LG G4] axel06:
Boy, you sure edited and changed your first "release" where you said:

"Wrong. Rovo89 needs to investigate this so that people who run stock ROMs can use WiFi Calling. Plus, this issue might pop up on other devices, so it needs to be investigated and fixed at its source - in Xposed."

What makes you think all the other devs (like Team Bliss) and I are wrong when they say it is now fixable within their own custom rom, just because you do not want a custom rom...Geez...That's why we flash custom roms, because they usually are better than stock!! Bye...
[T-Mobile LG G4] siraltus:
Boy, you sure are butthurt. I edited it because I decided that is NOT what I wanted to say. Quoting something I decided to retract and restate in a more civil way and then attacking me about it is a childish and pointlessly vindictive tactic.
[T-Mobile LG G4] axel06:
I know "Team Bliss" can solve wifi calling/ Xposed conflict. They are now able applying it to their custom rom being worked on (CM12.1 for H811). If you stay with the simple and humble LG G4 stock rom, well, talk to Xposed...
[T-Mobile LG G4] siraltus:
Most people use the stock ROM because CM camera quality is garbage. This is because of the proprietary image processing libraries and camera firmware that CM cannot reuse from the stock ROM or they'll get sued.

Given that most people bought the G4 for the amazing camera, they will continue using the stock ROM because of this.

This WiFi Calling issue needs to be investigated in Xposed so that its source can be pinpointed and resolved.
[T-Mobile LG G4] siraltus:
Strange, I tried using my G4 today and WiFi Calling is staying connected.

The only thing I have changed recently was to enable a secure lockscreen (pattern-based) that was required by Android Pay (which doesn't even work - I get "Card not supported" when paying at Walgreens or McDonald's).

I wonder if T-Mobile fixed something on their end or it's the secure lockscreen. Can anyone try using their WiFi Calling now?
[T-Mobile LG G4] jamesd1085:
Check xposed log in xposed installer app to make sure xposed is even loading...on 74 it was installed and Wi-Fi calling was working but xposed log showed it was loading no modules giving a placebo effect...it says a file or folder for preferences was missing
[T-Mobile LG G4] siraltus:
Oh, Xposed is loading alright, because I have 12 modules installed and they're all working.
[T-Mobile LG G4] jamesd1085:
Nice...i will have to try after i get back...my son has football practice...is it surviving reboots?
[T-Mobile LG G4] siraltus:
Yup, multiple ones, and it connects instantly now after each reboot or toggling WiFi off and back on. It's been staying connected for the past 3 hours now.... I wonder if it's just trolling me.

Can you try it without the secure lockscreen first to see if it's T-Mobile's doing?

I wonder if it's related to the massive iOS 9-related ****up with WiFi Calling and iMessage: https://www.reddit.com/r/tmobile/comments/3l921n/imessage_bug_in_ios_9_iphone_6_plus/

Maybe while fixing this, they also accidentally fixed our problem. :)
[T-Mobile LG G4] jamesd1085:
Lol...i will check tonite to confirm...i will also follow the android pay fix to see if it actually did anything in regards to Wi-Fi calling
[T-Mobile LG G4] siraltus:
It's still working... I really can't believe it. Let me know if it works for you.
[T-Mobile LG G4] jamesd1085:
Still working?...couldn't get any luck here...tried fresh install of rom and xposed with no luck...connected for about a minute then gone
[T-Mobile LG G4] siraltus:
Yeah, it stayed connected the whole night and into the morning. Did you enable a secure lockscreen?

I did open a ticket with T-Mobile engineering for this over three weeks ago, I wonder if they maybe finally fixed it on their end.
[T-Mobile LG G4] jamesd1085:
Yeah...sadly still a no go on my end...maybe they are rolling out fixes in different regions...I'm in Ohio...don't know how they do updates to wifi calling
[T-Mobile LG G4] siraltus:
I think the whole fiasco is about authentication. My GUESS (and it's just a guess) here is that we need to have some kind of certificate, fingerprint, or some other "this is allowed" bit of information on T-Mobile's WiFi Calling servers that matches our phones, and that somehow gets screwed up/modified when XPosed is installed. Maybe in my case, since I had the ticket open, T-Mobile engineering updated that bit of info for my account so that it matches what my phone's sending now so it stays connected. Again, I have no idea if this is true, but it's the only possible explanation for "it just magically started working again."
[T-Mobile LG G4] jamesd1085:
I created a ticket with them around the tim you started this thread...idk...i will keep tinkering...rovo89 has taken a few weeks away from xposed so maybe he will have an easy fix when he returns
[T-Mobile LG G4] siraltus:
Keep us posted... I have no idea why it just fixed itself. o_O
[T-Mobile LG G4] axel06:
In post #47 I asked a question that's very related to these last comments here. But, no response.

1-Now, Wifi Calling is designed to work when you do not have any data signal, but Xposed negates that on most LG G4 10N phones

2- So, why is it working - without interruption - with Xposed installed, as long as I have wifi plus just 1+ bars of T-Mobile data??

3- [MENTION=2317284]siraltus[/MENTION]: Do you have any data bars now (maybe that's why it's working)?

4- Can you try wifi calling with Xposed installed, with zero data connection - does it still enable your wifi calling?
