Continual Boot to TWRP [T-Mo] - G2 Q&A, Help & Troubleshooting

So for the first time in my history of Android's since the G1 I've finally bricked a phone. Apparently there was an OTA for the T-Mo devices and I managed to hamfist my notification and accept it.
Needless to say I'm now stuck permanently booting into TWRP. I've tried some various troubleshooting methods including doing what I thought was a successful sideload of the TMo-Stock-Rooted Rom. It showed a successful push and ran through the install but I got a message kicked back saying "No OS installed". Now I've seen other users receive this same message and after rebooting anyway they got their ROM to boot.
No such luck for me, after it reboots (post sideload install) it shows system as unmounted and then just boots back into recovery ad nauseum...I'm really at a loss here folks.

Have you already tried this?...

Hadn't tried it previously but I just attempted to run the ADB command and it still boots into TWRP. I'm not sure if those commands worked or not however. I got a big wall of text in terminal after the second command.
FWIW, on every reboot System is unmounted (Data & Cache remain mounted) but I can check it. Seems that it's irrelevant whether its checked or not.
Tried a sideload using the Stock Rooted 110G image and still nothing. Sideload appears to go, and install goes through without error but reboots only into TWRP with System unmounted.

can you get the phone to shut off and stay off. If you can then simply put it in download mode and use LG flash tool to flash stock rom back on. Please let me know if this is an option if not I will try and figure out something else

I can get it to shut off and stay off no problem. I'm on OSX at the moment and likely won't be able to get to a PC until the 9th. I'll definitely give the LG Flash tool method a try when I can.

yes I am afraid you are stuck in till you can get to a real man's computer lol. I'm just kidding though my girlfriend has a stupid Apple and I was stuck with the same problem I had to drive 50 miles to where I used to live to pick up my laptop to fix this. But the LG flash tool works like a charm and you will not have any problems. Just make sure that you read the procedure for the Verizon phone. If you are not surelookup the forum wink Link

Haha I hear you. I moved recently and the apt I'm in doesn't have ethernet drops so I had to order up a PCI wireless nic card =\ I'll dig around for the LG flash tool guides and see what I can learn.
I was hesitant to even flash a recovery because of how ass backwards LG made it for us in the first place =\

brother I feel your pain. But when you get everything all situated I will tell you the easiest way to install a backup recovery program. It is an app in the App Market called free GEE... One click and bam you have a backup lol.. You may want to use freegee to make sure twrp is installed right.. It will just over write all the files and correct any wrongs... Freegee.. Remember that!!

No worries friend! I almost went crazy last night trying to find a fix!! Here what fixed mine!
You need to be EXTREMELY CAUTIOUS when typing this in:
Go to Advanced in TWRP and run Terminal
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
then hit go
after it pushes through again type:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
then hit enter and reboot.

Are those commands pushable through ADB? For whatever reason when I get to the Terminal Command through TWRP it wants me to navigate to a different directory and there's no command line to type things in. I've always been a CWM flash a .zip kinda guy so digging into ADB is all new for me.

Ran the terminal side commands, got to LG Splash and we're sitting there now. We'll see how long it sits or if it's a boot loop.
**EDIT**
10 minutes sitting at the LG splash no go. I managed to snag an interim wifi adapter for my desktop so I'm going to try the Flash tool posted from earlier and see if it works.

Update
I was able to bring the phone back with those commands using adb thank you guys for your help.

Can't say for sure, I had seen some to run this way:
adb shell
then the 2 lines of prompt. I'm stuck on a boot loop so I'm trying to get the Flash Tool method to work. I should have not messed with G2 in retrospect lol, way too little support and far too big of a PITA to bother.

This worked for me. I tried several other methods from other threads but could not complete them for various reasons.
This also is the simplest method as it installed the update without my having to download it again.

Did you have any driver issues? I'm stuck in the same situation booting just to ClockworkMod Recovery after an attempted OTA update. Can't connect to Win7 because driver can't configure properly even with the latest drivers installed. Connects file with my wife's working LG G2 so I know the drivers are right. Also tried to get into download mode with no luck. I'm stuck. Does anyone know how to get pass this?

Problem fixed!!!!

OK. Finally got it working. Wish I had figured it out before I factory reset my phone. My main issue was the driver. Even though I had the right LG drivers installed, it just would not recognize it properly. Here is what I had to do after a failed device configuration.
- Go to Computer Management and find the failed device and Update Driver.
- Choose to manually select device and then select Have Disk.
- Find and select \Program Files (x86)\LG Electronics\LG VZW United Driver\64BitADB\lgandadb.inf (Tried the other xxxadb.inf files but none worked)
- When the list of devices is presented, scroll down and select LGE Mobile Server Single ADB Interface
Your device should now be recognized by adb. Follow the steps provided by others above in this thread and you should be good to go. Worked for me. Good luck.
Thank you all for the great knowledge base. Saved me $500!!! ::good:

Stuck in cwm recovery!! Help!!!

Okay, so here's my situation...
I installed TWRP with no issues, and a few days later installed CWM recovery (just because it's what I'm used to from previous device usage), but just today an OTA occurred. Yes, I'm an idiot and was warned not to do this and for that I am getting hit my some severe karma. Anyways, all I want to do is get my device working again. I could care less if it's stock, and I lose all of my data. I just want it to return to normal functionality. I'm on CWM version 6.0.4.4 and have no ADB support so I'm unable to push any files for a restore. Also, I have backups in my TWRP folder, but cannot access them from the restore from /sdcard menu. If anyone out there could help me out I'd be so damn grateful. Thanks!!!

Actually, I can't even revert to stock. Don't have any files that I can use to restore. Can't push them from PC. I think I'm out of options. Unless you can think of anything. Is there anyone I can directly get a hold of to help resolve this for me? I know I'm not the only one who has gotten this error.

FIXED!
If anyone out there needs help with this issue, I've found a very simple quick fix.
1. http://koush.com/post/universal-adb-driver Download and install this. For some reason it enables you to use ADB while in CWM.
2. Plug in your device while powered on and in recovery mode.
3. Now, enter the following commands in order.
adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
4. TA DA! You should be able to reboot your device in full functionality!
Note: The command prompt was copy and pasted by me from this forum --- http://forum.xda-developers.com/showthread.php?t=2451696
Big thanks to thecubed for getting me outta this one!

I am in the same situation. Please describe it in detail as to where to enter the command. Specifically where do I get "adb shell" and how to get this command prompt. Thank you so much
I was having the same problem tried everything to get it to reboot even the universal drivers still didn't work. I ended up using ubuntu and installing the jdk and sdk then ran the command that was in the TWRP tutorial (http://forum.xda-developers.com/showthread.php?t=2451696) and it worked like a charm. 9 hours though :/ hope this helps a little bit. if you dont have a computer running ubuntu just make a live cd and you can do it from that!
this was the link to the question I had posted.

Worked beautifully, after a few hours, almost gave up. This was so simple, it's aggravating.
same problem stuck in cwm menu

[Q] TWRP Bootloop ATT G2

Hey everyone,
As you can probably tell by the title, I am currently in a bootloop with TWRP. The story is as follows: I had the stock rom on, with a custom recovery. I noticed that there was an OTA update, HOWEVER, I knew that we should not install that OTA update because it would mess up our phones. So I come back to my phone to find out that it is in TWRP, so I go to reboot and then end up in TWRP again. I tried to backup and install new roms but that has not worked. Searching through the forums, I have learned that the OTA will install by itself without user intervention meaning that we can only delay the installation. I am assuming within the time period that my phone automatically installed the OTA and thus I am in this situation.
So I look at the FIX for this issue which is posted in the development section, I install ADB, etc. The only problem I having is that when I run adb shell, my computer can not detect my ATT G2. I noticed that you could also go into the terminal command feature of TWRP for that fix. However, when I click on terminal command, it does not bring up a command field where I can type things up. Instead it tells me to browse to a starting folder similar to a file manager.
I would appreciate any input into this matter
Thanks,
Zobabe
EDIT: THANKS to riggsAndroid in #lg-g2 I was able to fix it. I was being stupid and didnt realize you had to click "select" in the terminal command section of TWRP to enter the command.
ALL IS GOOD NOW.

Just asking but when you plug to PC your in fastboot mode right? Since you say twrp command prompt not working

friend accepted sprints new OTA. Phone wont boot past TWRP

So, I rooted my coworkers Sprint G2 or LG LS980 using IoRoot a month ago and had TWRP installed on it. prior to doing this I had looked into what it would take to revert it to factory unrooted unmolested state. didnt seem to hard with the lgFlash tool and what not....
Well two days ago he accepted and tried to install the new OTA. he was on ZVA firmware, and I believe the new OTA was for 4.4... well the install of the OTA failed im pretty sure do to TWRP being installed instead of stock recovery. instead of stopping there and calling me he tried to fix it himself... I believe one of the things he did was to wipe the device. as in advanced wipe, select EVERYTING including system....
He gave it to me today rather pissed and asked me to fix it.
Ok, I have bee through MANY threads about reverting back to stock, and it seems I am having a serious driver issue... In my laptops device manager I can see the LS980, but it has no driver installed. I have downloaded many different versions of the LG drivers from various tutorials here and on other websites. I even tried to find them on LG.com, but no luck there.
I can get it into download mode, holding vol+ and plug in USB, but once I try to connect to it via LGMobile Support tool or LGFlash tool, they do not detect it. it tries to load three different modems, and the center one always fails. is there anyplace I can get JUST the driver, not the entire self extracting EXE files?
I was just going to copy a ROM onto the internal storage, but even using the mount tab in TWRP it will not connect to my computer.
PLease for the love of all that is sacred to XDA help me!!! I sadly do not know much about ADB... I have never really used it. at this time it is not installed and I wouldnt know what to install and how to ADB Push a rom onto the phone...
Edit, here is ONE of the tutorials I tried, but since I cannot get the proper drivers installed this hangs when I click the yellow arrow to start it....

okay so have you tried the following from this thread-
If you DONT have ADB access (because of an early build of TWRP), you can simply use TWRP's awesome "terminal command" option to run the following:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You'll have to type that whole thing out, and be VERY careful with spaces and punctuation. One wrong letter and you could nuke your phone.

Ok, I think its TWRP 6.1.3.3? Maybe 6.2.3.3... not sure. Phone isn't in front of me this second. As to the terminal command... do I type the word code first? Or is it just there as part of your sentance, type this terminal code..... yea, I'm a retard sometimes. Thanks for your help.

Yea, I have been trying that method... my issue now seems to be that one of the drivers is not installing correctly. So I cannot change the device to port 41. And the app will not see my phone. When I get off work tonight and can use my laptop again I will try downloading advanced and setting that up and see if I can make it work that way. I also read the other thread that was linked last night looking for the two terminal commands to try, both the fota, and the miscellaneous command... found the commands, typed them in, and now my phone boots to the LG logo and my notification light starts scrolling through different colors. I can still get to both recovery and download mode though, so I am not giving up.
Also in that thread someone mentioned koush's generic adb drivers... I downloaded those and will try that as well.
Basically if I can just get my darn laptop to connect to this phone I think I might still have a shot at reviving it.
Multi color led makes me think, wing kernel. Like installing zvc kernel over zva system modem.
You may have to uninstall all lg drivers, and reinstall

Well it was running fine until he tapped accept on the ota so I dont know how he would have gotten the wrong kernel.... I have uninstalled the drivers a few times and reinstalled different versions. There is always one that fails when I plug in the phone. Plus I get a message on the device about mediadata unknown, or not found.... something like that. I know before he called me he tried the wipe option in twrp. I know on my galaxy s4 we were not to use the wipe data command in there, I'm thinking he did...
But I can still get to download mode so if I can get my laptop to recognise it I have faith I can lgflash tool it back to life... if I can get the drivers to cooperate...
Quick update on this... I found a tutorial on using adb and managed to sideload a rom, derp milestone 1 I believe it was, and after it completed the phone booted up just fine. My friend wanted it to be reverted back to its stock unrooted state, so I tried LG mobile something or other on my laptop... you all know, the one where you hit options then upgrade recovery and it should download and flash stick software? Well it saw the phone, and said there was no upgradeable software on it... mind you the phone still has a working twrp 2.6.3.3 on it... I don't know... I tried LG flash tool, but i can't get it to be port 41 for that to work... but at least the phone boots and runs fine now.
Still having my driver issue though. When I plug in the phone windows installs 3 drivers. One is CDC driver which always fails. No clue why.
Any ideas?

[GUIDE] Recovering from a bootloop without TWRP or KDZ/TOT

Please note: This will not recover you from a bricked device. This applies to bootloops caused by modifications you made, AFTER successfully rooting.
So you changed your build.prop or deleted a system file you shouldn't have? Your phone is now constantly rebooting? Your variant doesn't have a KDZ available? Here's an easy, albeit time consuming method to recover. (without TWRP or KDZ and no data loss)
First off, if you haven't caused a bootloop yet and you are doing a lot of modifications, do the following. Go to SuperSU and allow su requests on boot. This will allow you to fix minor problems during the bootloop, such as restoring your backed up build.prop or other modified system file. Many times, people will forget to set permissions on a file, especially build.prop. This will cause a bootloop.
If you GRANTED su requests during boot in SuperSU:
Say you set the wrong permissions on build.prop:
While your phone is bootlooping, plug it into your PC, then execute the following commands:
Code:
adb shell
$ stop
$ su
# chmod 0644 /system/build.prop
# reboot
Say you screwed the build.prop up and need to restore a backup you made to your sdcard:
Code:
adb shell
$ stop
$ su
# cp /sdcard/build.prop /system/build.prop
# chmod 0644 /system/build.prop
# reboot
If you DID NOT grant su requests during boot in SuperSU (or if you have tried and failed other methods to recover):
While your phone is bootlooping, plug it into your PC, then do the following:
1. Locate the image you used to root your phone.
2. If the image is on your phone still, just re-root. Your phone will be fixed.
3. If you deleted it from your internal SD card continue to step 4.
4. Open command prompt in folder on your PC containing image, then issue the following command:
This will take a VERY long time (20-30 minutes)
Code:
adb push system_image_name.img /sdcard/system_image_name.img
Note: If you don't have adb mapped to your environment variables, move the image into your platform-tools folder, or whichever folder contains adb. Then run the above command.
5. Re-root
Can't wait to try this when i get home. I soft bricked my LG G4 with a bad system.img so i am trying to restore. Is this actually going to allow me to push the img file back to the phone even though i cant boot?

In your case I'd say 50/50. It depends if it at least gets to the part of the boot sequence which enables adb.
I KDZ back to stock, then re-rooted to fix mine. No data loss.

That is a great method to use, but several variants don't have KDZs :crying:
I'm on the Sprint variant and am getting the Security Error loop. I have no system.img yet, however I can't seem to adb push anything (or see the phone with ADB at all)... am I doing something wrong?

That would not be considered a bootloop. That's a brick. I'm sorry, but in your case unless you already had a system image on your phone to flash, you are SOL until we get a TOT file.

Well i am able to access factory reset and i am able to get into download mode and see it from the send_command tool.. HOpe that means my odds are 100% instead!

Not necessarily. Download mode and factory reset(recovery) are located on different partitions than boot and system. Do you at least get to the carrier boot animation while attempting to boot? If so, your chances are good. If not, your chances are bad. The initial commands, including adb push have to be run while the phone is attempting to boot. NOT in download mode or recovery.

I get stuck on the LG logo where the light flashes on and off. While this happens if the phone is connected to the computer i hear the USB connection sound in windows. I will be trying it in a few hours.. hope it works!

Can I use this method to solve my particular problem (bypassing setup - I cannot move forward in the setup after a hard reset). Thanks (Can give you more info if you need it)

You may be able to. Does your phone boot? How far does it get in the booting process? If you get to initial phone setup, and can't get to the settings app to enable developer options and debugging, then you probably can't use this.. I'm not sure it would work, but you could try-During boot, debugging might enabled by default. (I'm not sure) Right when your bootanimation comes on you might be able to run the command:
Code:
adb shell stop
Then run the rest of the commands/follow this guide. It would be worth a shot.

I will try it. I can get into the phone to the screen right after entering wifi, then it just stalls. It doesn't freeze, but it also doesn't go anywhere. This is with wifi and data (I left the phone on for a bit and data picked up). If it's related, I turned on Voice Assistance and when the phone gets to the first set up screen she says something about Google play services not working and then "Hangouts needs Google Play services". That could be why I can't move on.....

I hear windows chime when it starts up, and the computer charges the phone. Running your command tells me: error: device not found.

How did you get in this situation to begin with? Are you able to get into settings at all?

Peeptastic said:
Factory reset because of the Google play error. Only it looks like Factory reset didn't fix it. And nope, can't get into settings because I can't get out of the set up screen (setup like when you first turn on the phone out of the box). I can get to download mode and stock recovery. As far as I know, there is no way to skip the original LG setup (clockwise button press doesn't work).
Can I adb sideload the image and try that way

Unfortunately that will not work. adb sideload is only for flashing .zip files.

every time I run the command while in bootloop it says "Device not found"

This is what is happening to me too. I can see that the phone during boot loop is recognized. I check the device drivers and it shows up under windows as LG.
Crap. not good.

Stuck at fastboot/LG Logo

I was having some issue with a rom and figured it was time to reflash/flash a new one. I started the process in TWRP and Aroma froze half way through. I had to reboot. Unfortunately I had already wiped my rom. I can get to fastboot, but I cannot get anywhere else at all. Can anyone point me to a way to get back into recovery?
Should have mentioned, H918.

Download adb to your computer. Connect the phone to the computer. Open cmd and use cd or pushd to point cmd to the directory where adb is. Once you are in that directory (from cmd), use " adb reboot recovery "
If what jinkerz9430 suggests doesn't work,
You may have to go back to stock. Here is how to do it for 10j:

Then you reroot as before.
Fixed!

Thanks for the response. I ended up rooting around for a long while after this post and settled on using LGUP and found the correct files to reflash to stock. Adb would not work at all. I could get fastboot access, but that is gimped. No driver update would fix the adb problem. I've never had this issue before, with any phone. LG seems to make things more difficult than necessary. I miss Samsung.
Thanks

That link seems to 404. I'd be interested in reading that though, if it isn't actually a 404. I believe what you are referring to is what I did though LOL. I found the kdz and dll, and used LGUP to get flashed back to stock. I'll never let it out of my sight again.

If you flashed stock with lgup then everything is back to factory settings. Is this is the case, then the autorization you gave to your computer via usb debbug (where the prompt appears if the device is connected to a other device without authorization asking you whether you want to authorize it or not). Is also back to factory settings. Which means not even developer mode is on. But after you turn developer mode on and usb debbug then connect the phone to the computer and it will ask you once again for authorization
