Stuck in TWRP - G2 Q&A, Help & Troubleshooting

Hello,
I try to experiment with my phone a lot. I think I overdone it today.
Had no GPS running CM10.2 and went back to stock rooted.
Had a message today there was an update (from Sprint). Installed.
The phone booted right to TWRP and keeps on booting there.
I tried to restore the CM10 back up with no luck, tried restoring stock back up with no luck.
Then I wiped everything clean. Still boots to TWRP.
I do have my backups on my PC.
I have no roms in the phone anymore so I cant flash anything.
Any suggestions?
Keep in mind I am fairly new to this. If I have to read up on something just point me to the right direction.
THANKS!
Dominik

This belongs in the Q&A section. Do you know how to use adb? Chances are that even sideloading a rom will not work. I had this issue not to long ago and I had to completely restore my device using lg flash tool. It just keeps rebooting into twrp? Try downloading a rom on your pc. Download the android sdk, navigate to platform-tools inside of the sdk folder, place the download rom inside this folder, hold down shift key and right click, select open command window here, open twrp on your phone and click advanced and hit adb sideload, type adb devices in the command window and it should list your device(you need your phones drivers first!), the type in cmd adb sideload (name of rom) without "()". it should push it to your phone.
If that method does not work you need to use the lg flash tool. download this to your pc: http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/Sprint+LS980/
look at the readme inside the folder and it will navigate you to the step by step instructions. Just make sure you use the Sprint files included in the link above and not the Verizon files. Steps are the same, files are not. It's very important.

One Click install TWRP Recovery, then root

I'm NOT responsible if you bork your tablet because you can't follow simple instructions!​
I've just made a simple batch file with adb, and the recovery file all in one zip for y'all.
Make sure you've unlocked your bootloader by following instructions HERE
1) Download Chainfires latest root and copy to Your Internal SD card on your tablet
2) Download and install DRIVERS
3) Download and extract nexus7_2013_recovery_A+.zip to a folder on your PC.
4) Open folder where you extranted nexus7_2013_recovery.zip
5) Make sure your tablet is powered on, and connected to the PC, then click on "Nexus7.bat" and follow instructions. (If your PC is installing drivers once it boots into fastboot, WAIT until the drivers are installed before clicking next!)
6) Be ready and hold volume up as the tablet will restart automatically, keep holding volume up until you reach the TWRP screen
7) Once in TWRP flash SuperSU/UPDATE-SuperSU-v1.43.zip
8) when you reboot Superuser will be updated automatically by the Play Store
Enjoy!
BIG thanks to Chainfire for his root, and team win recovery project for their fast work on the recovery!
07/30/13 Updated SuperSu link to latest revision (ver 1.51).
07/29/13 Updated SuperSu link to latest revision (ver 1.50).
For those that couldn't find their azzes if a target was painted on it, here's a link to the video.

ADB reboot recovery
Thank you very much for this, worked for me on the second try. Might I be so bold to suggest these changes to your steps to make them more clear? If not I will edit my post.
Edit - Didn't see you had a video. It didn't boot me into fastboot. I'm sure I did something wrong. Thanks again!!!

Umm thanks, but the bat file boots you into fastboot...watch the video
When you say copy chainfire's SU to the SD CARD you mean to the root of the directory you get when you connect via MTP, right? Where the Alarms/Download/Movies/Music etc directories are, right?
I see this syntax used a lot "copy to SD card" when there's not really an SD card, so it's a bit confusing (not just here). Especially since there's no obvious SDcard directory exposed when you connect via MTP to a PC.

Yes, you may want to create a folder in there for organizing all your flashable zips

Thanks guys, I haven't done much rooting / flashing with devices without SD cards before. I used the Nexus 7 toolkit to root the old Nexus 7. Everything I rooted before that had a real SD card to dump zips on - wanted to make sure where TWRP could access.
Looks like I'm still stuck at step 6. After running ADB reboot recovery, the tablet reboots and I see the dead Android with the red triangle. So I'm guessing Recovery didn't get flashed right.
So I rebooted it again. Ran the Nexus7.bat. It boots to Fastboot okay, and seems to be successfully after pressing enter a couple times. But ADB reboot recovery results in the red triangle again.

Try going directly into recovery right after the batch file finished and restarts your device. I had the same problem if I let my device boot and then reboot into recovery.

Yes, that was the problem. I started doing the steps manually and instead of letting it reboot after flashing the recovery.img, I went straight to Recovery from Fastboot and it worked fine. Thanks.

I dont know what happened but this did not work, I can still boot my device, but now I have no recovery installed. If I attempt to boot into recovery, i get the red triangle underneath it says *No command* I have tried to research the problem here but no luck in getting TWRP to flash.
Just curious why was this moved out of development? I'm glad I caught it yesterday before it was moved. All the past android devices I've owned have had their root instructions under a development forum here on XDA. I would have assumed since this device was so new the root instructions where not available yet. I admit it would have been my fault for not searching but as I said the precedence has been search the development forum for root guide. Just a thought, I know you moderators are obviously forum gurus..but I think a good portion of the community is used to finding them their. Even the OP thought it was the proper location.

Well honestly I posted the question mainly to have an intellectual conversion regarding allowing this to be in development until a alternate root method is posted.I mean I am not an android developer but I am a systems engineer for twenty years (by this I'm just simply pointing out I am of above average technical skill) and simply because I've always my root method for the past ...I'd estimate about a dozen android models I've rooted found root under development. So some others might miss it too

[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

LG G2 Fastboot

Everything I found on this says volume + and power, which kicks me into download mode, not fastboot.
I've gone into adb and typed adb reboot bootloader, but that just restarts the phone and turns in on like normal.
I google the how to enter fastboot mode on LG G2 and can find plenty of post about being stuck in fastboot, but nothing on how to get into fastboot in the first place.
Found a tutorial here about setting up and using fastboot and thought I was set until I got to the part about "and using fastback", where it just says:
Make sure you have android debugging turned on in your phone (not really needed for fastboot but you do need for ADB), plug it into your computer and boot into fastboot mode...
I felt like watching "Much ado about nothing" when Denzel says; "The learned constable is too cunning to be understood"
Any direction is appreciated.
Hmm, I may have written that guide... Just checked and yeah should have been more clear I'll change that up. It should have read the USB debugging was needed for adb (not for fastboot) so when you can issue
adb reboot bootloader
But after that I did mention to check device specific forum for answers on how to get into fastboot/bootloader and being I've never held an lg g2 I took a quick look around.
Unfortunately the only way that I found that people said works every time is to wipe recovery to get into bootloader mode as the recovery you guys currently have disables something due to a patch getting custom recoveries to work
So yeah, I would advice to speak with someone knowledgeable about your specific device before you just wipe recovery
Out of curiosity, is there something specific you need to do with fastboot or are you just curious about your phone?

the current thing I've been trying to straighten out is that despite being rooted and installing TWRP, I can't install ROMS. I tried CM 11 and Hellfire so that I could put kitkat on, but gave the following:
Error executing updater binary zip.
One of the answers I found said that I had to go back to TWRP 2.3 (I'm using 2.6) and I believe that's where the whole bootloader thing came into play, because it was the way to 'downgrade' -
So then I found Philz touch 6 (as I understand it a mode of CM 11), but here he talked about fastboot and lokifying items. Here's the link:
http://forum.xda-developers.com/showthread.php?t=2554053
In the end it still comes back to the "can't load ROMs" issue. Just want a completely stripped down Kitkat that I can add the stuff I want without the bloatware.
Thanks in advance.(and the thanks button was hit on your reply)
For KitKat you should need a newer recovery with SELinux support which I believe is 2.6.x and newer for twrp, 2.3 I doubt would work if there even is one for your phone
But yes fastboot is often the best way to change recoveries but not the only way.
If there is a flashable.zip you could install new recovery from old
If your current ROM supports the flash image binary you can use a terminal emulator
You can use adb to install
Or even apps from the market
I would look for the latest recovery for your device, twrp, cwm, shouldn't matter so long as its new and then find what way works best changing for your phone.
The update-binary issue is often a sign that you need to change recoveries
Unfortunately without having your device I don't know if I can give you the best answers but feel free to ask
Best of luck!

Thanks again. I have adb and the script for loading TWRP 2.6.xx. I unrooted and rerooted the phone, because I wasn't sure how to replace the recovery... Now I think I realize that I could just find another recovery image and place it in the same file as the loki flash and that will flash it (At least that's what I understand at present).
If that's the case, then downloading the Philz touch 6 would work... but not wanting to brick it, I'm still asking and reading.
Hello Guys.
I am having a similar issue. I have a new ROM that will not run because of a faulty lg set up wizard that always force closes and I can not get passed it and a nandroid that for some reason is corrupted. So. This fastboot seems to be a dead end it looks like a quick learning curve of ADB is the only viable answer. I have installed all SDK Manager with ADB Tools and also the required Jarva JDK and LG drivers. The phone is turned on (at the beginning of the faulty setup wizard) In CMD my device is found when typing in 'adb devices' So. I am already to push a new ROM over to the phone.
Do either of you guys know the adb command?
Help would be appreciated.
Thanks
You can't actually flash a new ROM with adb, but you can either push it phone with adb and then flash in recovery. Or if your recovery has an option for adb sideload then use this.
Also setup wizard crashing is usually the fault of wrong gapps or not wiping before flashing a rom

I found that the best way was to load flashify, that did the trick so I could start trying out ROMs... so no on to the next step - finding a 4.4.2 stripped down stock and the LG stuff I actually like.... thanks again.

Thanks for the reply!
I know it's not possible to flash a ROM via ADB. I have everything set up, ADB etc, etc. My phone is turned on and adb is seeing it but I can not work out the command to push. Every time I try to push I just get a long list of ADB instructions (I think they are) but nothing gets pushed. I have read lots of instructions on how to make the command but I still must be doing something wrong.
Here are my parameters;-
adb push/C:\Users\dene\Desktop/cm-11-20140210-SNAPSHOT-M3-d802.zip/sdcard
Am I missing some spaces I am not aware of? Are all my slashes the right way round and in the right places? Is my 'sdcard' destination designation correct seeing as there is only internal storage on the G2?
Another problem I am having is that ADB has no problem seeing my sevice EXCEPT when I boot in to recovery (TWRP). When in recovery I lose coms between my device and pc. Hence I can no do TWRP ADB side load (I have tried). I have all the correct LG drivers loaded. Except MTP keeps failing to install? Any ideas?
Not to be mardy about it or hassle you but I am fairly house bound and live out in the country and really require my mobile phone. I have spent many hours trying to figure this out. Any help with the above would be much appreciated?
PS. I did a very thorough wipe, I always do. The gapps are built in to this ROM!
Thanks

You need a space after push
But it usually easier not to enter the location of a file while pushing so cd to the directory first like
cd C:\Users.....
Then once there adb push /nameoffile /locationonphone
But if you don't want to cd, I see you have widows, depending on version you can just right click in the folder your file is located and choose open cmd here

As I thought I bought LG G2 D-802, but it was D-800 and I accidentally install the lollipop of D802 and now it's in bootlap.... I can only get into fastboot and whenever I try to flash .img of D-800 or D-802 it just stuck at "writing .img"
What to do to unbrick the phone and bring it back to live. I tired the adb and fastboot cmd method on windows 10 and windows 7 but no success. It's just stuck at writing .img file.

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:

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.

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

Hi there! I want to upgrade from android 6.0.1 to a newer, preferably the latest, version of android. I believe that is "A2017G-N-B09" as of the time of this post.
I downloaded A2017G-N-B09 (??) from the ZTE site, as linked in raystef66's thread. After putting it in the root of the SD card and running the update process, the phone rebooted as expected and said that the update was finished, but the android version is still showing as "6.0.1" (MiFavor is 4.0). The update shows in the update history but, as far as I know, nothing has changed at all.
After that, I looked around on the forums some more and saw someone mentioning that you might need to have Marshmallow B10+ before jumping into Nougat. So I downloaded MM-B11 from raystef66's thread, but the exact same thing happened.
Am I missing a step? Or am I using the wrong files to update? This guide mentions downloading the firmware (a separate file, apparently) before downloading and installing the update package. Is that what's missing for me?
I spent the last two days, since my new A2017G arrived, searching this forum (and google) for help with my issue, but haven't found any relevant solutions.
Many thanks in advance of any advice and help you might be able to offer me!
edit - I'm in the UK, if that makes any difference.

Can you try to install it again and read what the installation text on the recovery mode says? There's probably an error there.
Otherwise get an SD card, put the zip there, and go to the recovery (turn the phone off, and turn it on while holding volume up and power), then select to update from SD card and select the zip. If it fails or something, you'll have the text there, and you'll be able to write it down or whatever.
Also, what does the phone say on the back? Tell me what's the model as seen on the back. It might be an A2017 instead of an A2017G.

Thanks for the quick reply. The model says A2017G on the back.
I just tried to install through the recovery mode, as suggested. It says, "Sorry, you can't sdcard upgrade".
Is this something I can work around?

For the record, the zip file from ZTE support has an update.zip in it. So once you've downloaded it, extract it and put the update.zip onto your intSD/extSD.
I didn't uploaded the "ready" A2017 N-B09 yet on DownloadCenter.
As for the MM-B11 from Downloadcenter : this is a zip you can use directly. Rename it to update.zip, put on SD and update within settings.
Hope that helps you out.

Yep, that's what I did. Any idea why that didn't work then? I mean, it detected the "update.zip" when I had it on the SD card, and the 'update' appears in the history, but it clearly didn't install.

Strange.
Try to ADB sideload.
Also try to wipe cache in recovery. You'll never know.
Also try to rename to update.up and try again.
But then again, as you said the update was applying but nothing installed is at least weird. And also, when you tried to update through recovery and apply from SD, you couldn't is at least strange.
So try again with above steps.
BTW, where did you buy the phone ?

I got the phone from Gearbest.
I'm trying to figure out how to do all this. I'm brand new to ADB, so I don't really know what I'm doing. I downloaded the android SDK, and the universal ADB drivers. The device is showing up when I type "adb devices" and is responding to the "adb reboot bootloader" command, so it seems like it's set up ok.
So, the next step is to get TWRP on to the phone, right? I'm trying to follow the steps here, under the Fastboot Install Method (No Root Required) section, but it seems to be stalling at the "fastboot oem unlock" command. Just gets stuck at "waiting for device".
Sorry if this is all baby-steps. As I said, I'm really new to this and feel like I'm in a bit over my head. I'm happy to keep learning, though, as long as I'm not in real danger of destroying the phone.
edit - I renamed the zip to "update.up" and couldn't get that to work either. It's not detected in the update section of settings, and I still get the same "Sorry, you can't sdcard upgrade" message.
edit #2 - I tried naming it to "update.up.zip" and it detected it this time, trying to run the update now.

No you dont require TWRP for that.
Put the update.zip in adb folder.
Just type adb reboot recovery ( in ADB) . It boots into your stock recovery. There you can apply adb sideload (dont know the actual text : "apply update from adb").
Check that on your phone. Then phone is waiting to your command.
Then type : adb sideload update.zip (or ota.zip)

Ah, I should have mentioned that. This is the message I'm getting when I try that:
C:\adb>adb sideload update.zip
loading: 'update.zip'
* cannot read 'update.zip' *

Which is what made me think perhaps I needed TWRP on the phone. But, if that's all it should be, then I'm doing something else wrong...
Perhaps a driver is missing/not installed correctly? If that was the case though, how could I check? All the basic adb commands seem to be working fine and the phone is clearly responding to them.

You're doing ok.
When you can see adb devices with your phone's number you're ok.
So, adb devices / adb reboot recovery / adb sideload update.zip
Did you try to rename it to ota.zip ?
Btw, what version of MM are you running ?
Btw2, did you wipe cache/dalvik in recovery too ?
Perhaps you could root/bootloader unlock your phone (but you loose ota readiness ). And apply those system updates or install custom roms.
But again that's up to you.
There are threads about root/unlock your phone when on MM. Just look for it. If help needed just let us know.

Same problem when calling it ota.zip, " cannot read 'ota.zip' ". I'm trying to put A2017G-MM-B11 on there (although ultimately I want to get to A2017G-N-B09 if possible). My phone is on 6.0.1 currently.
Yea, I wiped the cache in recovery. Didn't seem to make any difference.
I'm not against rooting the phone or anything, but it just doesn't really seem necessary for my requirements, afaik.

Can you take a screenshot of your build number?
Go into settings /about phone and scroll down to bottom. Then take screen and upload it pls in attachment. Want to be sure what phone that you're on.

AFAIK, you're on B11 right? Also security patches are from that date imo. So perhaps download the first nougat B01 and see what happens and report back.
But it remains strange that the nougat b09 is in your update history, right?
If this nougat B01 as a test does not work, you may consider to wipe your phone. First backup though.
Is it possible it was flashed in incorrect order of update and messed up partitionioning a little bit, leaving some data screwed up?

Are you sure you are putting the file where you are in cmd? If you write 'adb sideload o' and hit tab, does the name appear? If not, put the zip on C:/, then write 'cd..' with 2 dots on CMD until you get to C:/, and try again
Usually the problem is that adb will get out of memory or crash because of some random thing. But try that nonetheless
lol.... just check 1 more thing... the zip file you have downloaded should be extracted first... and its normally contains 2 files... one zip and pdf file... and if the that zip files is not name as update.zip then just rename it and copy to your root internal memory... then check updates and install the update... it should be running then.
Sometimes i have this silly mistake as well until i open the zip files and saw another zip file in the downloaded rom and realized it.

Yes, that's what I was concerned about. The very first update i tried to install was N-B09, and everything else has been an older update after that, so maybe it won't overwrite the newer files, or something? Or possibly something else went wrong in the first update, so everything else just wouldn't work because of that?
I'm putting N-B01 onto my SD card right now, so I'll test that, and if it doesn't work I'll wipe the phone and start again. If I do need to wipe the phone, however, which update would you recommend trying first? N-B09? That might confirm if it was just bad luck on the first try, or whatever.

Agreed, that sounds like a possibility to me. I'll probably end up wiping and starting over.

Yes the tab autocomplete works on the "u" of update.zip and "o" of ota.zip, when I tried both. I have to admit, I was quite excited to see your suggestion there, as I thought that would be a really easy way to confirm if something isn't right with adb, but never mind.
I still don't understand why it gives me this error then, though: * cannot read 'update.zip' *.

Thanks for the suggestion, and yes, I did confirm that I renamed the right zip file. That would have been easy thing to fix though, sadly.
edit - I tried the same adb commands with windows powershell too, and got exactly the same error messages.
What ROM was on it before you flashed B09?
Updating to N-B01 worked! I've no idea why this happened the way it did, nor why adb didn't work for sideloading, but I'm really glad that it finally worked.
The order of events:
1) Installed N-B09 via transfer to SD using the android updater, no difference in android version, but appeared in update history.
2) Installed MM-B11, same as above.
3) Tried various methods of installing MM-B11, including:
- SD transfer
- recovery mode SD update (which the phone wouldn't let me do, saying, "Sorry, you can't sdcard upgrade").
- ADB sideload (which never worked even slightly. I always got the message, * cannot read 'update.zip'/'ota.zip'/'update.up.zip' *)
- Tried the above methods with variously named zip files, including "update, ota, and update.up".
- Tried the above methods, but wiping the cache in between processes.​4) Installed N-B01 via transfer to SD using the android updater. This time the process took a lot longer and after rebooting the phone, went through the process of optimizing apps, which it had never done before.
Ok, I think that's everything.
The only theory I can come up with is that: Something (I have no idea what, though) went wrong with the first update attempt and every subsequent attempt to update to an older version didn't work because it didn't want to overwrite newer android version files? That doesn't seem quite right to me, though, as I would assume that whatever is in the update.zip would just overwrite everything as standard, because the assumption would always be that these files are newer than the existing ones.
What would you recommend that I do next? Should I try to push through the latest N update now, then? Has this outcome helped you figure out what the problem was/is?
Whatever the case, I'm happy to finally get an update working. Thanks very much for all your help and suggestions, guys. It was much appreciated!
