Yeah I was wondering if it was the stock or debloated because in the past debloated had a file or 2 extra removed that ended up with problems like this (I think it was hotspot that would not work).

In this case, you are on the stock version so the fact it don't work is odd. I ended up flashing this as well because I have been waiting on the new 20v (HUGE thanks to [MENTION=2522637]MicroMod777[/MENTION] for this update even know I don't think you have this phone anymore?)

But yes, TL:DR, I also have same issue. I flashed the Imperium 7.0 kernel too, and it is still not working. Probably need a log, i'm not sure when I can get one if you can can you post from when you hit enable to when it goes back to disabled on its own?
[T-Mobile LG G4] br0adband:
No, it doesn't slide back, it'll just sit there. If I back out of the Bluetooth screen then go back into it it'll show it as Off but, as long as I sit there on that screen after sliding it to enable it the slider greys out and just sits there.

I'm not running that ROM anymore (running the actual pure stock 20v installed by KDZ/LGUP) and I've decided to stop tinkering with things for a few days, of course everything works perfectly on the true stock pure ROM so, we'll see what happens if I decide to do some more testing.
[T-Mobile LG G4] ApokrifX:
I assume you lost TWRP after KDZ/LGUP. Not a big deal to flash it back, if boot loader is unlocked still. Not sure if it’s the case, tho... I don’t understand still, how rooted stock ROM can break Bluetooth… “Things” were added to it, not removed, right? :confused:

Can’t you get log yourself, since you are on 20v now?
[T-Mobile LG G4] barcodelinux:
DISCLAIMER: My support is VERY limited. Couldn't find one so I made it. Here is a TWRP flashable 20v modem radio file if anyone else wants it. --> H811_20V Radio
[T-Mobile LG G4] br0adband:
Well, if any changes are made to the stock ROM files then sure, something can go wrong - Murphy's Law, obviously - but there's no way for me to specifically say what did go wrong. Yes the bootloader will remain unlocked until I sell it (have it listed on craigslist at this time) and I may do some more testing and experimenting but for now it's just pure clean stock 20v flashed by KDZ/LGUP and that's that.
[T-Mobile LG G4] ApokrifX:
I don’t know any other way to start digging, except getting log for LG-G4-H811-20V-Stock-Rooted.zip.

BTW: Are there any [relatively] detailed instructions how to prepare Rooted image from KDZ (or whatever)?

I.e. you got it ready to sell.

What you do [planning to] get for replacement?

BTW2: I did remember somewhat similar issue with Airplane mode (APM) on Kindle:

Change time to future date.

Turn APM off and on again.

Change time to current.

It won’t let me turn APM off, until current time reach the future date from 1st step.

Didn’t ever bother to figure out, what’s the cause...

Actually, don’t remember now, was it APM or just WiFi slider.
[T-Mobile LG G4] br0adband:
Another G4, of course, if I can get one at a rock bottom price which is somewhat easy these days as people are scared of keeping them around because of the potential for the bootloop to crop up. I don't worry about it myself, as noted above, if I get one that dies, LG is going to fix it and that's that. :D
[T-Mobile LG G4] ApokrifX:
I’m not sure, I’m following your logic. You want to sell one out of warranty and get another with warranty (from where)? :confused:
[T-Mobile LG G4] trieucyrus:
i updated my phone to version h81120v by LGup. but i can't root it by adb. anyone can root version 20v. help me
[T-Mobile LG G4] theslam08:
Not sure what you mean by "root it by adb". That is not how root works.

You can flash SuperSU directly after flashing the ROM (flash ROM flash SuperSU then boot). I use 2.79 with MM and it always seemed to work as it should.

SuperSU LINK: http://www.supersu.com/download
[T-Mobile LG G4] raptorddd:
LGUP will replace stocl LG recovery he needs to install twrp. and adb fastboot is required.
[T-Mobile LG G4] trieucyrus:
When lg g4 in version 20i i can install twrp throught adb fastboot. But now i up to 20v by Lgup kdz, my phone lost twrp. And i can't install twrp by adb fastboot.
[T-Mobile LG G4] raptorddd:
it should . the same way you did in 20i works in all 20o-20p-20q-20r and 20v. same procedure.

please explain more detail what you do and what happens including command in fastboot.

[T-Mobile LG G4] oari0909:
I'll Answer myself If I dirty flash WIFI button will not work nothing will not work

What I did, Cleaned system cache and dalvic and data

Fixed the problem

wanted to use the KDZ file but LG UP does not detect my phone nor windows
[T-Mobile LG G4] oari0909:
Well problems persist now I dont have the USB option on my phone no MTP selection just display "Just Charging"

Probably happened with the dirty flash to imperion in the first place

Wanted to use the KDZ but LGUP does not detect my phone nor windows
[T-Mobile LG G4] verbage:
I've ordered a used G4 H811 on ebay that will be coming in soon, and while I'd like to flash the 20V stock rooted rom, I don't want to do so if there are issues with Bluetooth. There didn't seem to be a final answer to br0adband's and theslam08's observation--has everybody that has used these roms had issues with Bluetooth?
[T-Mobile LG G4] grinch247:
What I got lastnight with this rom...
[T-Mobile LG G4] ApokrifX:
You have on 20V

7hours 59min 23sec == 7.989722222222222 hours

1320mAh / 7.989722222222222h = 165.2122518513368mA

I have on 20R

22min 44sec == 0.3788888888888889 hours

67mAh / 0.3788888888888889 h = 176.8328445747801mA

I.e. it's just different screen brightness, nothing else.

Or do you mean something else? :o
[T-Mobile LG G4] raptorddd:
means nothing.. we all use phone different i get around 3 hours SOT data connection.. using facebook app/messenger app and whats app. non stop back and forth.. auto brightness.
[T-Mobile LG G4] ApokrifX:
How come it "means nothing"?

We do compare screen mAh only which depends on its brightness mostly.

It doesn’t include apps you run (facebook app/messenger app and whats app., etc)

If you want to compare SOT regardless of apps you run, then you are absolutely right - it’s meaningless. :o
[T-Mobile LG G4] raptorddd:
if you check only screen then . try lower brightness and facebook app. would you get same as if you only see pictures or watch a movie? while doing some minor taks only lower frequencies will run as you run more apps the freq will be higher and it will drain battery faster. and we all have batteries that maybe too old. the only way is to do like a benchmark for a certain period of time.. even like that sometimes temp control kicks in. as phone gets hotter.

to me means nothing.
[T-Mobile LG G4] ApokrifX:
IMO, screen itself consume same mAh regardless of CPU frequency or temperature, only brightness matters.

When you play game on PC, does your monitor get any hotter comparing with other activities, providing screen resolution and frequency doesn’t change?

Ok. There is nothing to argue about then! :o

---------- Post added at 05:08 AM ---------- Previous post was at 05:04 AM ----------

[T-Mobile LG G4] ApokrifX:

Android security patch level mostly, I guess. :o
[T-Mobile LG G4] Godspeed123:
Owe so really no need to update?
[T-Mobile LG G4] kpirnie:
Its always a good idea to stay update mate.

Just take a look at whats going on with non-updated windows pc's...
[T-Mobile LG G4] ApokrifX:
No luck with Bluetooth on rooted 20V still, right? :o
[T-Mobile LG G4] kpirnie:
Im on a 20v rom (not this one) and have no issues with bluetooth
[T-Mobile LG G4] ApokrifX:
Interesting!

Somebody wrote before, bluetooth issue exists on all custom 20v based ROMs.

Bluetooth works on 20v stock ROM only... :o
[T-Mobile LG G4] kpirnie:
works just fine on mine
[T-Mobile LG G4] ApokrifX:
Could you try flashing MicroMod777 20V Stock Rooted ROM and check if Bluetooth works also, please?

Seems you are the one of few people here with H811, who might able to troubleshot Bluetooth issue… :o
[T-Mobile LG G4] kpirnie:
Flash a different kernel mate.

I wont be able to flash anything until closer to next weekend... on 4th of July vacation... and not wasting my data downloading a rom... aorry
[T-Mobile LG G4] NighthawkXL:
I moved back over last night from Lineage for the time being because of the need of Wi-Fi calling in my current area. My Bluetooth is still not functioning.

Which one then? I've tried both stock and Llama Sweet to no avail.
[T-Mobile LG G4] kpirnie:
Llama Sweet is aosp only now mate...

try imperium or simplegx
[T-Mobile LG G4] ApokrifX:
Stupid question, probably:

How does changing kernel can fix Bluetooth issue? :confused:

Bluetooth works just fine on stock non-rooted image (with stock kernel, right!)

I’d think, somehow radio was not updated properly during flash and interface mismatch cause Bluetooth issue or something like this.

Hopefully, logcat logs can shed some light...

NighthawkXL,

Did you do dirty flash or full one (KDZ, TWRP + rooted image)?

Just want to rule out radio not being updated... :o
[T-Mobile LG G4] NighthawkXL:
Full, I spent all night trying to get it working with no success. Ended up rolling back to 20q for the time being. At this point 20v is probably going to be our last patch unless LG decides to push us to Nougat. The G4 is already two devices behind so I wonder when they plan to EOL it.
[T-Mobile LG G4] kpirnie:
The only times I've ever had an issue with Bluetooth was when I did not clean flash a rom... LOS based, Stock Based, etc...

Each and everytime it was something that I did, that did not clean the partitions as needed.

What I would recommend to you, Format Data (not wipe... but format), Format System, Format Cache

Install the rom. done.

If this still does not work for you, KDZ the stock 20v image. Get TWRP back on it, re-root it, then flash the rom
[T-Mobile LG G4] ApokrifX:
He wrote (one post above yours), he did the latter already, didn’t he?
[T-Mobile LG G4] NighthawkXL:
For the most part. I did a wipe opposed to a format though, so maybe that was the cause. I'll give it a shot later.
[T-Mobile LG G4] ApokrifX:
I will be waiting for you result.

My thinking so far:

After flashing KDZ with wipe, you’ll get clean Android with working Bluetooth.

Some Bluetooth settings are stored on data partition, right?

Technically, if you dirty flash rooted 20v image - it won’t touch data partition.

But Bluetooth won’t work after, apparently…

Meaning either I’m wrong in my conclusions or something is wrong rooted 20v image. :confused:

And kevp75 thinks the stock kernel is the culprit here…
[T-Mobile LG G4] NighthawkXL:
No dice. Tried it with the latest Imperium kernel to no avail after doing what [MENTION=4819587]kevp75[/MENTION] suggested. Doesn't seem to matter whether root is done by SuperSU or Magisk (and removing root altogether doesn't work either). It's insanely frustrating? Is there any logs we can take for MicroMod or anyone else to look at?
[T-Mobile LG G4] stewie-droid:
Try flashing 20v rom and then flashing 20R modem and see if that fixes it. I suspect modem stays same anyway but maybe rom does not flash modem correctly and using flash of 20R may resolve that. Let us know as i want to try it too. Still on 10n lol
[T-Mobile LG G4] ApokrifX:
Logcat log, I guess.

It should be a way to get log including Android OS boot. :o

Since BT works on stock 20v, might be better/easier to remove modem from MicroMod 20v rooted image?
[T-Mobile LG G4] liokocode:

[T-Mobile LG G4] probi115:
Can I flash this over 20q with a full wipe or do I need to be on 20r
[T-Mobile LG G4] kpirnie:
Should be fine.
[T-Mobile LG G4] tinhipvt:
I flashed 20V from 20R using the Stock Rooted Rom in first post, At first, I used radio from 20R, but the wifi button went crazy on 20V, so I flash the 20V rom again (still the same file) and it s working fine now, no any Wifi or BT prblm yet, hope this help :eek:
[T-Mobile LG G4] ApokrifX:
That’s the very first successful result we got.

How did you do it exactly?

Just deleted modem.bin from LG-G4-H811-20V-Stock-Rooted.zip?

Did you just do flash twice, without any wiping, etc.?

What do you use BT for exactly? :o
[T-Mobile LG G4] tinhipvt:
Well, I am a super noobie, so I am not really sure how to correctly describe what I did.

So I used adb to reboot the phone (20R) and install TWRP recovery, then used TWRP to install 20V Stock Rooted zip file in the first post, then install 20R radio zip file (in this thread https://xdaforums.com/tmobile-g4/development/rom-lg-g4-h811-20r-stock-rooted-rom-kdz-t3545130), then superuser zip and Xposed framework, no wipe (like any kind of wipe, i didn't hit any button has the word wipe on it lol). Then I restart, the phone boot up, automatically installed some apps, when everything was done, I noticed that the wifi button on noti was going crazy, turning on and off repeatedly, but the BT worked normally. So, again I used adb to reboot the phone (20V) and install TWRP recovery, then used TWRP to install 20V Stock Rooted zip file in the first post again (no radio this time), then superuser zip and Xposed framework, no wipe. The phone boot up, install some apps, then works normally now, no Wifi prblm or BT

So yes, I kind of installing the same file 20V twice, and no any kind of wipe,

I am using BT to pair with a headset play music, well the headset does play music so i guess BT works :fingers-crossed:

http://imgur.com/a/NzauJ
[T-Mobile LG G4] ApokrifX:
>Well, I am a super noobie

Beginner luck? :o

So, in short it was:

Initially had 20R (I assume: not rooted, no TWRP)

Installed:

TWRP recovery

20V Stock Rooted zip (with 20V radio)

20R radio zip (i.e. overwrote 20V radio installed on prev. step)

superuser zip and Xposed framework

Restarted:

BT works, WiFi – not works

Installed:

TWRP recovery (was there already)

20V Stock Rooted zip (with 20V radio) (was there already, except 20V radio)

superuser zip and Xposed framework (was there already)

I guess, after restart it might be sufficient to reinstall 20V radio only from post #22 in this thread?
[T-Mobile LG G4] NighthawkXL:
Replicated these steps (using the Debloated ROM) and can report that swapping the radios back and forth seems to fix the BT issues some of us have been reporting with rooted 20v.

Pop up Playstore ads

Just dirty flashed the debloated version over 20r on my wife's phone. She now gets periodic full screen ads for playstore apps. Have never had this before, and it has been on Micromod rom since new, first the Xtreme and then the 20r. Have done some searches and have found ways of stopping this in chrome, but this seems to be independent of chrome, though I am not completely positive on that.

[T-Mobile LG G4] raptorddd:
you this guide .. but the part that says to use 20i KDZ skip that you are already in 20v.. because we have antirollback. 20v its V3 so you cant flash a V2.. so V2 is 10n lollipop 20i MM...( thats why am telling you not to flash this skip this 20i).. then we have V3 that is 20o-20p-20q-20r-20v. you can flash either of this as they are all V3.

[T-Mobile LG G4] ApokrifX:
So, what is short sequence then?

Keep flashing 20R and 20V radios until BT start working?

Sorry, just came back from vacation... :o
[T-Mobile LG G4] NighthawkXL:
Step 1: Flash 20R KDZ.

Step 2: Flash TWRP.

Step 3: Dirty Flash 20V Rooted or Debloated ROM. (Optional: Remove or replace the old version of SuperSU from ROM's Aroma script)

Step 4: Flash 20R radio, optionally update root, kernels, mods.

Step 5: Complete initial setup. Power on Bluetooth and Wi-Fi.

Step 6: Reboot to TWRP and flash 20V radio.

Step 7: Profit.

That's what worked for me.
[T-Mobile LG G4] MLD100:
I couldn't get it to work. I bought a stock, rooted R (on ebay) for my wife. Also it had TWRP. All appeared good but I decided to do a factory data reset. Don't know why but I lost root. I hadn't switched my wife yet so I decided to try these steps. Plus, I was getting the annoyning 'update is available' notifications. Here is what I did:

1. Full backup with TWRP--that proved beneficial

2. Dirty wipe (Dalvik and cache, no data)

3. Flashed the stock rooted zip from external card

4. Flashed the R radio from external card

5. Phone will not boot, hangs on the bootloader LG logo initial display

6. Flashed the V radio--same as before--boot hang

8. Back to TWRP, just for grins try a factory data reset--same as before boot hang

9. Back to TWRP for a full restore--that works fine, so I'm back where I was.

Any idea what I might have done wrong? One thing that gave me pause is that after the full backup the external card only had about 2GB left of a 16GB card. I wondered if there might not be space to extract the zip (which is 1.5GB). But no errors.

Many thanks
[T-Mobile LG G4] NighthawkXL:
I'd go grab the 20R KDZ and use LGUP to restore the phone back to stock. Perhaps something in the original rooted ROM was messing it up.

Then from there follow my steps in my earlier post.
[T-Mobile LG G4] MLD100:
Thank you for the reply. At this point I have supposedly stock R, TWRP (2.8.7.2) , bootloader unlock, oem unlock and SU flashed (2.7.9). Perhaps, a silly question from a non pro but I wonder what else I need to do to get root?
[T-Mobile LG G4] ApokrifX:
Thanks mate.

I assume, I can always update SuperSU later, not necessarily immediately after flashing ROM, right?

Why do you recommend to do it before flashing ROM? :confused:

You need to flash rooted ROM, flashing SU to stock ROM is not enough. Tho, I'm not a pro either... :o
[T-Mobile LG G4] NighthawkXL:
Mainly because if you allow Aroma to install the included old version of SuperSU, you won't be able to install Magisk. It will fail at patching the boot image.

Specifically, if you want to remove the included SuperSU, and flash Magisk instead append your update-script inside the ZIP file at META-INF/com/google/android to this.

Crap battery life

Issues with battery life... wondering if anyone else has a similar experience and and/or has any suggestions.

I was running stock unrooted 20v and I was getting horrendous battery life as well as a TON of Google Play Services wakelocks. A few months ago, I was getting 3.5-4h of screen time easily, now I'm down to 1.5-2h with very light use despite trying 3 OEM batteries (1 brand new). It's hard to say when or IF there was a sudden change but this is certainly different from the phone in June/July.

Multiple factory resets didn't do anything and the wakelocks were present no matter what (checking via traditional battery stats, also BetterBatteryStats and Wakelock Detector, unrooted). I bit the bullet, unlocked my bootloader and installed the debloated 20v rooted rom to try out, in case it was some of the LG/T-Mobile bloatware. Thanks by the way, it's a perfect ROM.

After successfully flashing the rom (clean flash) I'm still getting lots of Play Services wakelocks even with literally no additional apps installed. I tried older versions of Play Services which seem to run much lighter, but it just ends up self-updating silently. There are ways to block the update but it still wakes up to download the files, wasting data also.

The wakelocks in question are mostly location related (NLPWakelock/NLPCollectorWakelock mostly) but also some PackageManagementServices, net_scheduler, LocationManagerService, WifiOffDelayIfNotUsed, and a couple more.

I tried the usual- wiping caches, disabling location history, location scanning, disabling location altogether, Greenify, etc. I finally tried Amplify (paid version), blocking different combinations of the above wakelocks starting with just the basics, and this seemed to help. At best I'm getting around 2 hours screen on time with very light use at low brightness. Overnight, I had 25% battery drain from 100% -> 75% in about 8h.

Maybe the phone is broken. It's been repaired 3 times at this point, the board supposedly swapped each time, though I don't see how hardware failure could lead to unnecessary wakelocks.

I searched the thread and forums and while poor battery life is a common complaint there's little information on wakelocks specifically, especially relating to the H811 on 20v, and most of what I could find seemed outdated.

I'm wondering if anyone else is affected and if you've found solutions. Thoughts?
[T-Mobile LG G4] metropical:
the G4 is an utter pos. Mine went back for a mb "refurb". Worse than before the 1st one failed. The screen is peeling under the touch surface in addition to the issues you have experienced.

I factory reset once a month or so and restart or blow the cache once a week.

My 1st (flip) phones were all LG and very good. My HTC M7 is more stable than this running the same apps and it's 2 or 3 years older.
