Need help!!! Cannot boot into twrp - LG V20 Questions & Answers

Ok, I'm going to start by explaining everything I did up to this point to eliminate any troubleshooting sugggestions i may have already done.
I rooted and installed recovery the same way everyone else did. After a couple of days, I tried to install a ROM but im assuming i was encrypted because i was stuck in a loop that would only boot me into TWRP. Did my research and took the necessary steps to get around that and decrypt and boot into the new ROM.. FINALLY!!! Only one problem, this rom doesn't have Super SU installed, Alright... so i download the proper Super SU build and put it on my Micro SD card and try to boot into TWRP to flash....
This is where the problem begins. I never get the prompt to authorize my PC from my phone to allow anything, and i never did each time i reset. I'm almost certain the adb on this rom is messed up, i've wiped about 4-5 times to re-enable usb debugging from scratch in order to adb or fastboot into recovery via command prompt, however when i try adb, i get that unauthorized error an there's no option on the LG V20 to revoke under developer settings. Fastboot i just get the same "waiting for device" message. Also keep in mind that i set it to photo mode, every mode that was available and nothing. Tried different USB Cords and did this on both my laptop and my PC at work
I've tried uninstalling and reinstalling all of the drivers, re-installed the latest version of adb and fastboot to my PC, that didn't work either. Tried deleting the adbkeys file in the .android folder and still nothing.
When i try to boot in recovery manually, i just get the wipe data option and when i click yes to everything, it actually wipes my data. I'm unable to reflash TWRP because I can't access ADB or Fastboot due to the unauthorized error.
Someone, PLEASE HELP!!!!

any luck?

different route but im in the same boat. any luck?

I fixed this shortly after. Wanted to avoid returning to stock as. The only option was you and I was on 10d. I had to go back to stock but luckily the recovery method still works.

Fastboot> Recovery dosen't find *.img file on SD card

Hi Guys!
I am trying to root my nexus, unlocked it, installed the right usb drivers, I can see the phone and everything looks right.
Downloaded Superboot for ERE27 with himem enabled and ran this. no problem.
I put the img file on the SD card and when I boot the phone in Fastboot / Recovery it does not find and img files on the SD card.
I tried 2 different cards and also different img files.
When I do this I get first the message no images found than I see the droid with a triangle and a ! in it. - Have to pull the battery.
Ideas anyone?
Thanks
What are you trying to do?
1) you had to unlock the bootloader which enables you to install a new recovery image (which is needed to allow you to install new roms)
2) you had to apply the recovery image Amon RA via a command prompt and a batch file if you use Windows. The phone's USB connection needs to be in development mode and once the batch file executes and successfully finishes you need to reboot the phone.
3) you restart the phone into bootloader mode, use the volume rocker to select the recovery console. If you end up with an andriod and exclamation symbol the Amon RA recovery file was not installed.
4) the new recovery console allows you to clean the SD card. Install roms from the SD card and some other commands. The Roms for the Andriod are in ZIP format and do not need to be unziped. In other words all you need to copy to the SD card is the full ZIP file (approx 75MB) and install that directly from the recovery console.
If your android stays in the booting sequence which is shown as the X with flying little pixels, it's most likely because you did not wipe the device clean first. That item is in the recovery console as well.
Hope this helps. I am just as new to this as you are.
You didn't unzip them did you?
You're trying to root with superboot. Great, but the recovery is not capable of flashing .img files, only .zip updates and roms and such. .img files have to be flashed using fastboot, not recovery, and are flashed from the connected computer.
If you read the superboot instructions from wherever you got the file, you'll see that you have to put the .img in the same directory ON YOUR COMPUTER as fastboot, connect via USB, boot the phone into fastboot, then enter the appropriate command line on the computer to flash the file.
If you've done that, then you are officially DONE with the rooting process.
Also, make damn sure that the superboot version matches the software version on your phone. They're both ERE27, right?
I'm not sure what anosis's post is talking about, but that looks more like the process for installing a custom rom (ie cyanogenmod), than rooting.
To root your phone, you DO NOT need Amon-RA's recovery. You only need that if you want to install custom roms, etc. It wont hurt to have it, as it includes many more functions than the stock recovery, but just to root, you don't need it.
Summary:
If you flashed the superboot.img from your computer via fastboot, your phone is rooted. Done.
You don't need to do anything in the recovery at all for rooting. Only for installing update.zips and custom rom.zips.
Hey, So I have been scouring the forums trying to find some answers about this and you seem to be the closet to my situation. Here is what I did:
So I was running a CM9 Aplha, reverted back to stock 2.3.6 [1ada25375426.signed-soju-ota-189904.1ada2537]) so that I could then apply ICS update [VQ8PQk_V]) which I sucessfully did. This was about a month ago and it was all going well.
Then yesterday I wanted to upgrade to 4.0.4 [hR7QFEtn] so I did and superuser wasn't working properly but then I reinstalled it and got it to work. However I got to the point where everything was working fine EXCEPT for the Google Play store kept on force closing. I spent hours trying last night and could not find a solution.
I tried restoring the previous ICS update that I had and it worked, and then I tried updating again. Also side: My clockwork was on the fritz lately so I was using Zedowmaxs force into clockwork recovery image [fastboot boot recovery3101.img] to force it in sometimes.
Anyway bottom line here is where my REAL ISSUE begins. I decided just to wipe everything and start anew. I factory reset/ wiped properly [cache partition and davliche cache] and then locked my bootloader again. Then tried rebooting. Got stuck on Google screen. Then I unlocked my bootloader again. Tried again, same issue.
So, here is where I am at. Cannot get into recovery from fastboot, takes me back to fastboot. AND, everything is wiped because I locked/unlocked my bootloader. All I can do is adb commands.
I don't know what to do from here and there is a lot of things going on. If you could help that would be great!? What I am going to try next is to flash some recovery on, but I don't know which one/ try to mount a file to my sd card from adb commands.

It looks like the time when you were locking-unlocking the bootloader, you messed up the recovery. Since your phone can get into bootloader menu, I think you can get out of this issue.
Here is what I would do.
1. Unlock the bootloader.
2. flash clockworkmod recovery using fastboot USB.
3. Download recovery-RA-passion-v2.2.1.img, put it in C:\fastboot\
4. Shut down your phone. Then start your Nexus One in Fastboot mode by holding down the Trackball and press the Power button.
5. Connect your phone to your computer. Open a Command Prompt (Start -> All Programs -> Accessories -> Command Prompt), and run the following commands:
cd C:\fastboot
fastboot devices
fastboot flash recovery recovery-RA-passion-v2.2.1.img
now see if you can get into recovery. If you can, just flash a custom rom using install zip from sd card option in the recovery
I didn't read all the replies but fastboot reads from your PC's disk not the sdcard, unless you are running it through shell or something?

[Q] Super Ultra Brick (WITH VIDEO)

UPDATE 3: I've got it back to as stock as I can get it. I think I'm going to just return it and get a new one. Thank you all for your help.
UPDATE 2: As of right now, I'd like to completely remove FFF from the device, but I can only use fastboot to do it. I have absolutely no adb access. Is there a way?
UPDATE: Here is a video showing what is happening to my KF: http://www.youtube.com/watch?v=MH6oUg1NmC0
I hate to start another thread about boot loops/bricking, but I'm not sure what's going on with my fire.
I had CM7 installed successfully since the day after Christmas. This morning I woke up and my Fire was being really sluggish, so I rebooted it (I did not select reboot into recovery).
After it powered on, I was stuck at the CM7 boot screen (with the skateboarding android). I let it sit, but no luck. I went into TWRP to try and restore the backup I made of the stock rom. It looked successful, but when I rebooted I was stuck at the Kindle Fire boot screen.
Next, I tried wiping the device and re-installing CM7, but I received an error (something along the lines of E:Error unable to find /tmp/sideload/blahblah).
So I again restored my backup of the stock rom. Now when I power on my Fire I see the yellow triangle, then the kindle fire logo, yellow triangle, kindle fire logo, and it just keeps repeating. The problem is I am unable to connect to adb because the PC only seems to recognize the adb device for a few seconds after the yellow triangle, which does not give me enough time to fix the problem.
Any ideas?
looks like you'r out of battery ! the kf is rebooting !
would take the wall charger and charge for an hour
it's not possible to charge with the computer - it lasts forever
then it should respond in a stable state

Recovery shows my battery level to be at 53%. I've got it on the charger now, but I have a feeling there is something else going on.
Also, I am unable to mount my Fire's SD to my computer in recovery. It looks like it is working, but my computer never acknowledges it.
maybe because your last installation failed
nevertheless i would try to charge and then go in twrp and retry the installation
if that's not sucessful i would try to switch the kf to fastboot and copy a new rom. stock or prerooted stock or cm7 - whatever you like
in twrp there is a point "mount" - sdcard - then you should get it from computer

Thanks for the reply. Is adb required to get into fastboot? The problem is that I am unable to get into adb because my computer only sees the Fire for about 1 second. When I go into device manager, I don't see it at all.
EDIT: Yeah, I see the mount in TWRP, but it does not do anything when I select it.
Hi Im a beginner but Id like to try to help :
In case you become desperate ignore twrp's battery display and try wall charger.
Anorher idea id have is to shut down throughr twrp and start up then instead of rebooting.
ADB is needed to get into fastboot, but it's quick. If you use KFU, you can probably hit the option during the couple seconds you have available. I would say your best bet, however, is booting into twrp, doing a full wipe of system, cache, davlik cache, and maybe data, and then trying the rom install again.

So this time it looks like the installation worked in TWRP, but after reboot now I'm stuck at the CM7 boot screen. This is at least some progress, so when I get home I'll see what I can do.
Sent via my internet connected mobile cellular telephone.
Well, the battery is definitely not the issue. I've been trying to get fastboot, but the problem is the fact that I can not get adb. Has anyone else had issues with getting adb? I've already tried to install the drivers, and that doesn't work.
EDIT: I've tried issuing "adb devices" from the command prompt repeatedly as soon as I hear the ding until it disconnects a second later, but still I have had no luck.
Also, I found this thread in which someone else appears to have had a similar issue to mine.
[Q] New kind of unfixable Super Brick?
at the moment adb is useless - you should try to get the device in fastboot mode - correctly recognised from your computer - then work with fastboot commands - if you don't get that then your next opinion is buying or making a factory cable - but we should try to avoid that ...

I can not seem to get fastboot to work either. Does fastboot rely on adb? Or do you just run the .exe file? I tried to run it, and nothing happened.
fastboot has nothing to do with adb - calling just the exe does nothing -
you have to issue fastboot commands
ok have reread the whole thread and have some ideas:
your currently stuck at the cm7 boot screen ?
have you used the "stock rom version" to wipe data and cache partitions as described here ?
http://forum.xda-developers.com/showthread.php?t=1390773
perhaps it will help to wipe data/cache with twrp ...

Just wanted to let you know I updated the OP with a video showing what is happening to my KF.
Haven't tried that particular rom yet, but I have wiped data and cache and attempted to re-install CM7.

OK, so I restored my original rooted kindle rom, but I still can't get into fastboot because of the problem I showed in the video. It is doing exactly the same thing, just instead of the CM7 boot screen, it is the Kindle Fire boot screen.
Is is possible to get into fastboot without the computer? Can anyone think of a reason why I would not be able to mount my device in TWRP?
I just want to understand something about fastboot... can you upload and flash roms with it? Or can you only get TWRP / FFF with it? I ask because I already have them, and I still can't do anything (mount from inside TWRP doesn't work). Thanks!

with fastboot you can install the newest fff and if you need twrp
but with the newest fff you can issue ""fastboot oem format"

Cool. I just ordered one of SkOrPn's cables, so once I get it I'll be sure to give an update. Thanks for all the help so far!
The cable isn't need when you have the FFF bootloader, in fact, when your computer does see the device for the short amount of time shown in the video, fastboot is active. It's a feature of FFF. Fastboot is a command line tool like adb but is used for different things. It comes in Android sdk which if you have that, you should update the tools packages in the Android manager and it will update adb and fastboot. It looks like something is not working correctly in twrp and the OS is failing to load. I'm not sure you need to oem format tho.....
At some point you had to have used fastboot to install twrp and/or FFF.... Unless you used adb dd? :what:
Anyway, I can help more but it's late where I am, need to sleep. Was going to write more but... Need sleep lol. I'll post some questions and check back tomorrow.
Have you used adb before? Do you know if platform-tools is in your environment variables PATH? In other words, can you open up cmd and type adb or do you need to "cd" to platform-tools then use adb? If you know where adb is located? If so, is a file called fastboot in there? (Maby called fastboot.exe)

Yep, I've used adb successfully, and it is set up as an environmental variable. I actually installed FFF and TWRP with the KFU. Problem is I think something else is botched; perhaps it is TWRP itself, since I am unable to mount from TWRP. I'll try again when I get home.

[Q] bootloop, usb debugging not enabled, no back up, help!

Alright here is my situation. I ran the latest OTA update on the stock rom and the phone started going into
a boot loop. My problem is that I havent performed a recent backup and need to access some files on the
phone. Developer mode is enabled, however I disabled USB debugging prior to running the update. When my
phone reboots, I remove the battery and restart the phone but every once in a while my phone successfully
loads and I am able to punch in my pin to unlock the phone. However, a few seconds later the phone reboots.
I tried to access the phone using ADB but because I dont have USB debugging enabled I dont see any devices
when I run the "adb devices" command. I also tried to acquire a smartphone image using encase forensic, but
yet again, because USB debuggin is not enabled, I am not able to pull data.
I am able to go into recovery mode and I tried to wipe my cache partition, but that did not help.
My questions are:
1. Is there a way for me to access my data files while the phone is stuck in a boot loop and USB debugging is
disabled?
2. Is it possible for me to download the latest update, copy it over to my sdcard and rerun the update from
my sdcard from recovery mode? Could this possibly solve my problem?
3. In a worst case scenario, if I do a factory wipe/reset, will this solve my problem and what is the
likelyhood of recovering my files from the data partition?
Any tips, tricks, advice is greatly appreciated.

Thanks svs57 for the quick reply.
Would you mind elaborating a bit more? I am an IT guy but by no means a developer. When I boot into recovery is the phone supposed to show up in My Computer via MTP or PTP? The phone is not showing up as a device. Or am I supposed to use adb commands to pull the files down?
When I go into recovery and run the "adb devices" command now I get what appears to be a serial number followed by the word "unauthorized". I rebooted and went into recovery mode again this time tried "apply update from ADB". When I try using either the adb push or adb pull I get "error: closed"
Thanks again for the help.
You have to use latest version of adb. Then you can login to phone via adb and find file you want to backup. Then use "adb pull" to get file to PC.
If you have custom recovery you also can make backup you data using recovery.
Also you can flash the same ROM you have without wipe data.

Stuck on TWRP without a system to boot to.

Hi, I wanted to return my g2 to stock rom because I didn't like my custom rom, so I followed the lg flash tool guide(tot):http://forum.xda-developers.com/showthread.php?t=2432476
It worked, but it was jelly bean 4.2 instead of Kit kat 4.4, so I tried to install TWRP so that I can install again a custom rom, but when I tried to backup before flashing TWRP, it wrote "backup Failed", I tried again and it wrote it again, but then the phone just stayed on the boot animation for a few seconds and didnt turn on again. After that, again I tried to do the flash tool method just to return to stock rom but now, it just doesn't work, whenever I insert the DLL and TOT file and start the installation, it goes up to 80% extremely quick and just boots up to TWRP without actually installing the stock rom. So now I'm stuck here with TWRP but without a system to boot to and no rom on my sd card to flash.
I really need help here because I have no idea how to continue.
Thanks for any help!

You could load the zip you want to flash to a USB drive, then connect it to your phone with an OTG cable. TWRP can read from OTG.
Can you get into download mode? (phone off, hold up volume, insert USB cable connected to computer)

I just tried to do it through an OTG cable, it said that it flashed successfuly, but when I restarted it just went back to TWRP without booting up the system. Also, when I tried to wipe dalvik and cache, it said "wipe failed.". When I rebooted it said "It seems that the device is not rooted"... I really don't know what to do now And I can get to download mode.

Can you get ADB connectivity from within TWRP if you connect your device to the PC?
If so you could do the following command from your computer.
Code:
adb push ROM.zip /sdcard/Download/
Then navigate to your /sdcard/Download folder and flash the ROM.

TWRP should detect your phone without the need for ADB sideload.
If I boot into TWRP, I can instantly run "adb devices" from the terminal my phone is picked up as a "device".
If I choose ADB Sideload, my TWRP hangs just like yours does, but if I run another "adb devices" command my device shows up in sideload mode, regardless of it hanging.
Conclusion, try running the adb commands without running sideload in the first place.
Edit: Upon reflection, this is most likely because I have created an RSA key between the PC and my phone.

I just tried to do it through an OTG cable, it said that it flashed successfuly, but when I restarted it just went back to TWRP without booting up the system. Also, when I tried to wipe dalvik and cache, it said "wipe failed.". When I rebooted it said "It seems that the device is not rooted"... I really don't know what to do now And I can get to download mode.

Did you wiped absolutely everything before flashing? Do you have previous Nandroid backup you can just flash. Anyway if you connect your phone to PC while in TWRP what does your PC show. Anything?

I tried to wipe but it just wrote "wipe failed". I do have a back up on my computer but for some reason when I try to connect my phone to my computer through an OTG cable, it doesn't find the backup. And my pc doesn't show anything when I connect my phone.

Can't flash ROM's or use USB to ADB to flash/restore original Android OS.

HI all,
I've come from flashing Samsung S4's for years but after trying to flash an update I got the boot screen and nothing happens.
Here's the situation.
I had originally installed PureNexus, rooted, unlocked the boot loader and probably turned off USB ADB settings (and I don't typically want an alert when plugging in the USB cable) as I usually transfer media and ROM's to the download folder for future flashing.
I saw that 6.01 was released and saw that the bootloader and radio were updated. So I tried to flash those before updating with PureNexus 6.01.
I did a nandroid backup before I did this, knowing something might go wrong.
I think my camera wasn't working so I tried a nandroid recovery to get it back.
Unfortunately I didn't read about the password encryption bug which TWRP had as I did the restore in my car and didn't have internet as it was free down time. When it was completed, I got the failed password issue. So I decided just to format everything. I used TWRP and formatted everything including the vendor partition. Of course, I forgot it would delete the Nandroid, too. I'm too used to having a spare external SD card to store all of the Nandroids on.
Anyway after that I can only get to TWRP.
I've tried installing the original 6.0 ROM, PureNexus ROM through TWRP with the appropriate ZIP files. It says it's completed, no errors but just the boot screen.
I've tried restoring through ADB with Windows 10 and through the USB. I don't get to an ADB selection on the bootloader, but can get to the ADB sideload throught TWRP. The problem is when I tried to restore through ADB nothing happens as it says "waiting" when I use fastboot flash-all. ADB devices does give me an ID when I do ADB so it is connecting. However, I believe ADB is waiting for the USB-ADB to be turned on which I can't do because I can't get to the OS system partition.
I've tried using several of the Skip Soft Toolkit and again, it waits and says closed.
I'm assuming that USB-ADB is closed and not turned on. I don't know why TWRP can't overwrite the system partitions if I try to flash, unless it's still encrypted but shouldn't be as I formatted everything, except for the boot loader and that is unlocked as I get the screen that I should lock the bootloader because the OS can't tell if it is corrupted.
Any ideas? I can only think if someone sends me a Nandroid of a configuration that may flash it back to a level I can get into Android and then get back to USB ADB and do a clean install with fastboot flash-all.
Please help!! Thanks in advance for your suggestions. I hope I gave you enough information to help me out.
Update. I apparently found a way. Luckily TWRP has a Flash image feature as well as flashing the vendor image. Flashed PureNexus 6.01 and PureNexus Gapps and thank goodness that worked! No idea why ADB was not flashing except for the configuration for USB ADB was turned off on the ROM originally.
