1. Did you guys not follow the directions when rooting to create a backup of the initial, non-rooted system.img?

2. What about re-flashing the rooted system.img?

Assuming you can reflash either original or rooted system.img, would booting into factory recovery and doing a factory reset work?
[Sprint LG G4] ironbesterer:
No no no. Do not factory reset while rooted. You'll continue to get bootloops. You will just have to wait until the KDZ is released.

Welp, looks like I'm returning my phone.

[Sprint LG G4] jaxbierley:
Pardon my ignorance, but it looks like there is a .kdz file for the G4. Will that not work? I honestly have no clue how .kdz or .tot files work, but I trying to figure out the difference.
[Sprint LG G4] centran:
Somehow messed up my phone using google cardboard of all things... well at least that is what I was using when it rebooted and went into a boot loop. I rooted it days ago and the phone has rebooted since I did it with no problems. I have not done anything with root yet on the phone but for some reason cardboard sent it into a boot loop. I tried reflashing the rooted system image but that didn't work. My phone is now pretty much bricked. There is no tot file and it is impossible to transfer a file onto the phone or sd card(can't mount sdcard) to try another system image.

This is a disaster for me as I bought this through best buy. I'm hoping I can get LG to re-flash the phone and give me the same exact phone back. Why? The plan I signed was for a leased phone. I worry that if I use the warranty and get a new imei number phone that I will void my lease and I have to purchase the broken phone out-right. But I guess if I get another phone I would just be where I would be 2 years down the road anyways.

Only problem is I was double stupid and did the wireless charging mod so I now wonder if LG would even look at the phone let alone getting warranty to replace it.... however, the warranty place probably wouldn't even notice the sticker was changed.

So I have no clue what route to take. On top of all this since I am on this stupid Best Buy plan I can't re-activate my old phone. Only Best Buy can do that. Now I am phone-less to boot. I wonder if Best Buy will even activate the old phone for me.... I guess I will find out tomorrow. If not I will have to pay $5 more a month to change my plan to the official Sprint plan.

If this all turns to crap I might just eat the lease cost, warranty the phone, re-sell and get something else. I am done with this phone.

Has any of you contacted [MENTION=4654107]Sj12345[/MENTION] ?

He made this tool for us over at the G Flex 2 forums and people have been able to restore their phones back to booting normally.

There is a catch as allways... he needs a full backup of system.img from your phones and you have to be able to access DOWNLOAD Mode.

Good luck guys.

Here is the forum check it out.

[Sprint LG G4] 1230clock:
Would the tar.gz file or underlying system.img from here work? When I rooted my phone with that image my camera would get errors where the camera has stopped or the device would freeze up and restart a lot.

I'm guessing we need a fresh nonrooted img or tot file. We just need a fresh img or tot file. Can't wait to revert back to complete stock/make a backup/rerun root

http://downloads.codefi.re/thecubed/lg_g4/lef/LS991ZV5.tar.gz
[Sprint LG G4] Alex_XV6700:
I guess it would be better to use a clean non-rooted system.img

But if someone that is rooted and has no trouble with any app can pull their sys.img that would work for you.

Remember the way this restores is exclusively for GFLEX2 so I always suggest you should contact [MENTION=4654107]Sj12345[/MENTION] for guidance, He´s the man.

I just saw y´all had a similar problem to ATT GFLEX2 users no TOT/KDZ.

[Sprint HTC One (M8)] rauma:
Hello guys, I have tried to find a clean ROM for my M8. By clean I mean that it is a stock ROM with all Sprint stuff removed.

Actually, I flashed the Bad boyz ROM, it is nice but i do not like much. The ROM which Im using is the GPE version.

I try to flash the stock ROM also but there is many Sprint stuffs that I dont need and because Im using GSM network so it always asking to convert to Global network any time I restart the device.

My question is: Is there any ROM that is like the M8 world version (Sense, no carrier stuff), unroot?

Thanks.
[Sprint HTC One (M8)] buggerman:
You can just remove the carrier stuff after installation. I kept getting "Hands free activation" popup but when I removed some apks, it worked just fine.

You can try switching the cdma mode to ruim only in dfs or something. That should help in not showing up the global mode popup.

[Android One (First-Generation) Cross-Device Genera] F4uzan:
Just use ADB and get the bootlogo back. Alternatively, you can flash back a stock firmware (not stock OTA, but a stock firmware) of your phone model to get it back.

After loading scatter file on SP flash tools, select only logo and flash. OR copy-paste the logo.bin file in platform tools and use "fastboot flash logo logo.bin" to get that logo back,,,
[Sprint LG G4] andrewwm:
Hi. This post is for those that don't want to root (if you are already rooted you can still follow this) but want hotspot. This method is similar to the LG G3 but some how works on the LG G4 without root.

I made a video. Enjoy.

https://youtu.be/j3Di9d7w1so

It's safe to upgrade to ZVB as long as you do the trick below.

Some good news, a few people have figure out a way to keep the tethering. It requries you to downgrade back to LP (if you are on marshmallow)

(Directions created by Bombillazo, thanks to antonio824

1) On ZV6, used the steps to get to IOT menu to change APN settings.

2) Selected LTE settings > APN settings. Open the App close button (square one on the bottom menu) and check that you have separate instances for the ITO and APN menu. THIS IS CRITICAL DO NO CLEAR THEM OR CLEAR ALL!

3) Applied the MM update (ZV9 and or ZVA).

4) Let the upgrade finish and reboot.

5) When finished press the square button again and go to the APN settings window. You should be able to select the n.ispsn APN again and add dun to APN type. (NOTE: IOT will close if you select it but it doesn't matter. The important one is the APN settings window).

6) Congrats! You have Wifi tethering with MM!

7) Just in case you wanna test like I did, don't close the APN settings window and try to update system stuff to see if it changes the APN settings. I can confirm that updating your profile on the System Updates menu will undo the APN type change.

In MM, you can pin apps to the recents menu so it can't be cleared by "clear all"

Welp, this is the end folks, the new Marshmallow update (ZV9) has patched this trick. Feel free to try it to make sure but as far as I know, it doesn't work. Had a great run!
[Sprint LG G4] iiEatTurdz:
omfg i love you.
[Sprint LG G4] pcrhckyman:
Thanks so much! Now unlimited data has a proper use ;)
[Sprint LG G4] crdnl.:
Just going to add, if, after enabling tethering, you get a popup saying "Due to network issues, tethering has been disabled, go through the same steps and select cinet.spcs instead of internet in the APN settings.

You are the man. Awesome and easy to do. :laugh::fingers-crossed::laugh:
[Sprint LG G4] kyle1867:
As far as I can tell this just bypasses the check to see if tethering is enabled on your plan. Can't they still tell that the data traffic is tether traffic? After all it does show up under mobile data as "Tethering and hotspot"
[Sprint LG G4] andrewwm:
I don't think they even check if the data is coming from tethering or phone use. How do custom roms work? They just enable hotspot without checking same here.
[Sprint LG G4] bwillet:
I'm not worried about Sprint monitoring data usage... Normally I hover around 10-15Gb per month usage, with a moderate amount of tethering. But about two years ago, I used a Galaxy Nexus hotspot as my home internet for about 9 months with no issues. Downloading ISOs, streaming, VoIP, etc. Regularly over 100Gb usage, never a peep. Stopped doing it because I got sick of listening to my wife complain about having to restart the phone every few days. In retrospect I should have just put a tasker script on there to reboot it nightly and toggle the hotspot back on.....
[Sprint LG G4] KingFatty:
Anyone with MellowMallow ROM, how do you enable wifi tether? I downloaded QuickShortcutMaker, but cannot find the correct technique (No search results for programu, for example).
[Sprint LG G4] smashclash:
Anyone else recently get a Sprint ID - Sprint Default OTA update? I woke up yesterday with the notification. I'm afraid if I install it I'll lose this tether option. Anyone install it yet but still have the ability to use this tether hack?
[Sprint LG G4] tabp0le:
That's just for a Sprint app. (Sprint ID) If your profile gets updated it may reset your tether modifications. Worst case scenario do it again.
[Sprint LG G4] cdurd770:
Major issues possibly related to this?

I'm not knocking this method or anything, but maybe someone could benefit from this or point me towards what may have caused this issue for me. I have a brand new, unrooted LG G4 with sprint. I've used it a few weeks, found this thread and got my wifi (woot woot). Two days ago my phone started rebooting, almost like a boot loop. It wouldn't come back on and get to the lock or home screen. Just constant lg and or sprint boot up screens. I eventually just booted in recovery and factory reset it, but that left me with no data. I had to call sprint to get a code to dial to reset my data related information. I did check my settings after factory reseting and the "dun" was gone from that string, but still had no data. I want to use this again but am wondering if anyone else is having this issue, is it related to this, or is my phone broken or is there another issue out there causing this that's totally unrelated?
[Sprint LG G4] boraxman:
^^^^No issues so far.....Will be watching here though, dont want to go through all that/
[Sprint LG G4] andrewwm:
no idea why, faulty device?

That shouldn't happen at all. You should have taken your device to the Sprint store if the problem was easy to show them.
[Sprint LG G4] KingFatty:
So far no issues here, been using the easy modification to add "dun" to my settings with no ill effects. But I use the wifi hotspot very rarely, so maybe it relates to how much data you use where if you use up a certain amount of data, Sprint might take a look around if you hit their secret magical threshold that draws their attention?
[Sprint LG G4] kyle1867:
Yes, this is true. They throttle you if you use a lot of data. I ran a speedtest with my coworker, also on Sprint Spark, his speeds were 5x faster than mine.
[Sprint LG G4] wilsonch1551:
No issues for me either on Sprint and this was one of the first things I did to mine and it's been three weeks.
[Sprint LG G4] Integerated:
The best point is that no root is required for this method. I have tested it and this method is working perfectly. Thank you for sharing it :good:
[Sprint LG G4] Mahapederdon:
Sprint hates me right about now. Haha. Thanks for this.
[Sprint LG G4] jlv3:
I tried this and can't get the hotspot to work. I added ",dun" to APN type both under "internet" and "cinet.spcs", but no matter what, when I enable the Wi-Fi hotspot, I get the prompt saying that tethering is not enabled on my plan. I must be doing something wrong, but I've got it exactly as you do in the video.

(the only oddness is that while I'm testing this, I'm at home connected via an Airave, but I really wanted to be able to use this next week when I'll be in proper Sprint coverage)
[Sprint LG G4] uapyro:
I know with the Note 4 and Hotspot hack, it doesn't work in Airava coverage. So it is probably that. I was just checking this out because I'm considering a LG G4.
[Sprint LG G4] MyzDevyneOne:
You are da goat.
[Sprint LG G4] jlv3:
it's working for me!

Thanks! Here I am on the road (away from my Airave) and this is working just fine... in fact, I'm posting this from my laptop.

One hitch... every thing I added ",dun" to APN Type, I'd hit the 'back' button, and it would immediately erase the ",dun". Eventually I realized I just needed to switch away from those settings and the ",dun" would stick.

SInce this is set under the LTE settings, does this still work if I'm on a 3G connection? I guess I'll find out shortly as I'm going to be in Maine away from Sprint's LTE buildout.
[Sprint LG G4] KingFatty:
Try and re-test it when you are connected to a cell phone tower. Mine works fine nearly all the time, except that I get the same prompt you did about the plan, when I test the phone inside my work building. So maybe it has to do with the signal you get, because I think my work uses some repeater thing perhaps similar to the Airave but not sure exactly what my work uses. If I go up to the 6th floor my phone connects to the Sprint cell phone tower and the wifi hack works like a charm then, no error message. My work could also cause roaming on a Verizon repeater too, I'm just not sure?

But my point is just not to let your current test environment make you think the phone behaves that way all the time, and that I had similar let down when I tested inside my work building but the issue for me went away once I used the proper sprint cell tower.
[Sprint LG G4] jlv3:
You missed my post right before yours.
[Sprint LG G4] KingFatty:
Ah, oops! But another thing to mention about the hitch you encountered, is how you can immediately save the results without needing to wait. The trick is to hold down the square button for a bit, which brings up a menu to "Save" the results. Then you can immediately hit the back button and the settings will already have been saved. Pretty unusual to need to manually save like that, especially since the option is hidden behind the square button.
[Sprint LG G4] AngelosDracul:
BEAUTIFUL! I love this phone so much, and I really didn't want to go through the hassle of rooting (had it since launch, and haven't felt the need to root at all). I Deejay on the weekends and sometimes in areas with no wifi, but great LTE coverage. THANK YOU! For real! You just saved me tomorrow! lol
[Sprint LG G4] mswlogo:

[Sprint LG G4] mswlogo:
What do mean have to reset? reset what? for what?

You mean reboot after using hotspot?

I know on the M9 they disable IpV6 on Wan0 in a init.d boot script. But I'm concerned that's what causes some instability when using the phone normally.

P.S. There is a disable IPV6 app in the playstore (that is not sticky across boots).
[Sprint LG G4] viperkota:
lol, no clue how i missed this. just finally found it today doing a search thru google and posted the think in another lg g4 tethering thread.
[Sprint LG G4] mswlogo:
This is not working for me.

I so happen to be roaming right now. I keep getting MIP : 67 error followed by a message box saying it's not on your plan.

I am not rooted and running ZV5

Will WIFI Tether Router work if I root? I was hoping to avoid the headaches of being rooted. I got this phone because I thought I could tether without root.
[Sprint LG G4] mswlogo:
Well I figured it out. This does NOT work if you are roaming.

I like to use tether on long drives while I alternate with my wife driving.

We will hit spots of roaming and everything goes down rather hard. Takes a while to get back up again once you error out on roaming.

I'm curious if I root and use Wifi Tether Router (which requires root) if that will work when roaming.
[Sprint LG G4] mswlogo:
Damn, I swear I had Wifi Tether Router working in roam mode.

I went to test removing ,dun in the APN's and Wifi Tether Router did not work. I put them back and it still does not work (roaming).

It works for like 20 seconds. It's possible I didn't wait long enough the first time when I checked it. Something shuts it down.
[Sprint LG G4] andrewwm:
I have great service here I don't roam often. Keep trying and rebooting the phone. Also try turning off roaming to pervent it from happening.
[Sprint LG G4] mswlogo:
It refuses to work while roaming. No problem on M8,M9,S5.

Works fine if not roaming.

There is an ugly roam gaurd message that pops up on boot. Even if I click don't show again, it does. I have played with roaming settings.

It appears there is an extra level roaming guard running in addition to the usual stuff.
[Sprint LG G4] mswlogo:
I think I understand the problem a bit more with no roaming.

It's eHRPD vs EVDO. eHRPD is only supported on Sprint towers. All the roaming towers are CDMA/EVDO.

I need to dig into the other devices and see if I can see why they work and how they connect.*

Also note that all the apns are under LTE which covers LTE and eHRPD. Which is the only formats that tether.*

This is explained in the OP of the original G3 wifi tether hack that this came from. But does not explain it's impact to roaming only that LTE/eHRPD will only work. and EVDO will not.
[Sprint LG G4] andrewwm:
The APNs affect LTE and EHRPD, that is it. CDMA/EHRPD don't have APNs because they work differently regardless if you are roaming or not. If you roam a lot, that is a different problem. I will test this myself when I get the chance but for now, the hotspot bug will only work if you are on EHRPD or LTE.
[Sprint LG G4] mswlogo:
Isn't that what I just said :)

Curious how devs managed to get my M9 & M8 hotspot to work on CDMA/EVDO. They modify APN's too and also disable IPv6 on the Wlan.

I don't roam a lot. When I want to use hotspot it's often on long trips and my wife and I take turns driving. We will hit a roamed spot and it will knock you off PITA. It gets real unhappy and sometimes even requires reboot to get it back up once out of roaming area.

If I'm in areas with LTE that often means I'm at home or work when I don't need hotspot.
[Sprint LG G4] ijball:
Anyone have tried this using the ROM included in the TOT method. For some reason, I don't have the Tethering menu, so even if I can edit my APN, there's no way to turn on the hotspot.

Tried Wifi Tethering apps from app store and it shows me a tethering menu with little/no settings that I can play around with.

By the way, I'm outside US and not on a Sprint network.
[Sprint LG G4] mswlogo:
This hack only works on LTE/eHRPD. It won't work roaming on another network.

I'm not sure what the hack will do in GSM/Global mode.
[Sprint LG G4] SantinoInc:
This is a great hack and easy to do!
[Sprint LG G4] Sangie:
Doesn't work for me. It just causes the phone to go to the Sprint Spark splash screen doing a half reboot. I'm rooted running LZ5

I've tried adding ,dun to both Internet and cinet.spcs.

I should add that I have quite a few things frozen with Titanium Backup that had LG in the name. Is there anything specific I shouldn't have frozen for this?

Fixed! It was a frozen LG app. I unfroze the non-apps by LG and it worked right away! So if using this fix crashes your phone, see if you have any apps you frozen in Titanium Backup.
[Sprint LG G4] wilsonch1551:
I'm glad this got bumped today I had forgot to do this after the ZV6 update.
[Sprint LG G4] Alvien89:
I've performed this successfully... sort of. I'm tethering and my devices are connecting. However, on my G Pad it's telling me that the network has no internet access. Google.com is loading and making searches with no problems, but none of the links that I select are loading. Excluding Netflix lol. I can access the website and use the Netflix app on my tablet, but nothing else seems to work. A peculiar thing is that I'm getting chinese menus when I access the Netflix website, while I live in Savannah, GA.

Any ideas or suggestions?

(I restarted my device and reestablished my hotspot. I'm now editing this via my WiFi hotspot. I guess it was a weird roaming issue?)
