TWRP Boot Loop after OTA - G2 Q&A, Help & Troubleshooting

I hit the update tonight not thinking and before I had disabled Xposed.. Now my phone is stuck in a boot loop to TWRP. I have tried to wipe dalvik and cache, tried the adb shell commands that work for most people, tried to restore a backup, but none have worked so far.
I am trying to download the stock file to revert back to stock, but it says it will take 2 hours. Any help for the weary?
Is this the only way to get it working again?

I had a similar issue a couple days ago, problem I think was due to TWRP not having "RT -RM" (? - sorry I'm not looking at the exact text right now or have it memorized) option checked in Settings in TWRP, or possibly due to issue of older TWRP version, .2 and the newer .3 works better. My System directory was unmounted and couldn't come back, stuck in boot-loop until I followed the revert-to-stock directions. I had to download the 2 gig file, taking about 2 hours, and it contained readme.txt w/ instructions and all files needed to revert, but it was very tricky. A .DLL must be overwritten in Windows to get the LG firmware flashing software to work right, and you need the .TOT file. It will work if you are diligent, so don't give up hope. I thought my bada$$ new phone was bricked but finally got it to flash back to stock using that method, possibly similar to the quote in this thread, http://forum.xda-developers.com/showpost.php?p=48434571&postcount=1150, using Verizon instructions / sprint files. You can get it back. Mod will probably lock this thread as it is not development so follow that post I just linked, along with the OP. I am in Windows 8.1 x64 so I think it can work on any version of Windows.

Oh and this thread should probably get locked as it shouldn't go in dev section, mod will probably move or lock it. Hope you figured it out.

What I did ti fix diwnload mode
I took the rom I last flashed. Opened it. went to the system folder and extracted the build.prop (opened it with notepad). Press the find button in one of the drop down menus and find the model number your g2 thinks it is and change it to what it actually is.( in my cause mines had a d801 rom so it thought was one instead of an ls980) I changed mine from d801 to ls980. Saved it (make sure its saved as build.prop). Now go into the rom you originally got the build.prop from and replace it with the new one adb push the rom to the phone in twrp then flash it. Then boot into download mode and flash away

Thank you very much! Work great!

I am dealing with the same issue,
i've had the Optimus ROM installed
and decided to try out cloudy, the phone was rooted and unlocked.
after wiping in TWRP and installing the new rom phone fails to boot to system and goes to recovery automaticly.
i know i could fix this by installing everything from scratch (STOCK).
NBreunig3's solution doesnt work for me either.
what am i doing wrong in the process?

Save the headache, flash stock 4.4.2, towelroot, autorec and start over.

Yeah that is exactly what i did (used ioroot25, and the autorec app is amazing!!), but since i didnt have anything installed on my pc i had to download everything from scratch
and a simple 20 min process became a multiple hours one (trying to avoid that in the future).
anyway i've got the cloudy ROM now and it seems that it is already unlocked so i got that going for me which is nice .

[GUIDE] Install ClockworkMod Recovery image after updated to 2.3.4 (GRJ22).

Not applicable
Delete this thread
Hello, thanks for the post.
I got a brand new Nexus S, I got a update direct from Google so I just flash it to GRJ22 :-(. I follow your guide (I have to do the step 1/2 in the other post you refer). Now I got clockwork done. But everytime I restart my phone, I always boot into clockwork. I try to 'mount sdcard' and reboot, but still boot into clockwork. How can I boot into the stock ROM?
many thanks!!
Too complicated.
Just:
1. turn on phone by holding volume up + power to go to bootloader
2. fastboot oem unlock (confirm it on the phone)
3. fastboot flash recovery recoveryfilename.img
4. Select recovery on the phone.
5. You're in ClockworkMod. Go flash a new ROM.
Let me answer myself.
I don't think the latest rom 2.3.4 is compatible with the clockwork you supplied. So I have to flash my phone back to GRH78. I downloaded the stock ROM from the internet. and then push all the images file into /sdcard/clockworkmod/backup/2010.xxx.
Next, I restore the image in clockwork menu.
after restore, reboot the phone, now I am back in business.
When the phone is boot, i lost the root again, so i went to modaco.com and get Paul's package. run it, restart, I got the root.
Finally, go to market place and get ROM Manager, install the clockwordmod. and I have a 'proper' phone.
although I don't have the least rom, at least i got a working phone that is rooted.

I have the same problem. How did you handle it?
Wow, why risk messing up your phone with flashing a boot.img when you can just rename /etc/install-recovery.sh to something like /etc/install-recovery.bak?
Here's one way to rename (courtesy of Matridom). Another is to use Root Explorer.
Matridom said:
The new update applies the install-recovery.sh script into our phones (not there previously.
Boot into the bootloader
flash CWM
select recovery from the bootloader (DO NOT reboot the phone)
apply the su binary
boot into the OS and test root
make sure busybox is properly installed
run ADB shell
then:
Code:
su
mount -o remount,rw /dev/block/mtdblock3 /system
mv /system/etc/install-recovery.sh /system/etc/install-recovery.bak
Boot back into the bootloader and re-flash CWM, should stay permanent now.l had applied the SU binary at the same time as the OTA update, then renamed the installer script and flashed back CWM.

This is a totally unorthodox way to make the custom recovery permanent. If your phone is messed up, good luck fixing it.
There is a much easier and safer way like I mentioned.
PS: flashing recovery for 2.3.4 is the exact same as for 2.3.3!

I am sorry but not all people can successfully use Command Prompt to do so.
I cant use command prompt, as it says "Image cant be loaded".
So I had to use this method.
I search around the forum and seen this as a quite common problem,
so I decided to share it
Hope you understand.
Anyway, thanks for your method too Cheers

The CWM Recovery I supplied is version 3.0.2.5,
which is not compatible.
So I replaced with version 3.0.2.4.
You just download it at the link above and follow all the step again.
You should able to solve this problem

Wow people like to make things complicated. Why install an entire rom to get ride of a script?
if you can flash cwm, you should have some basic understanding of fastboot, adb and the search options in the forums. the answers are all there already.
Sent from my Nexus S
No disrespect, I agree flashing recoverys should only be done after you understand how to use the tools to do it. there is no reason someone who is going to mod systems on their nexus shouldn't be able to use fastboot and adb properly. all the right drivers are in the sdk.

This is what I did.
I rooted my NS, which had 2.3.3
Used phone with stock 2.3.3 until I figured out which ROM I want to flash.
Before I flashed any ROM, did a Nandroid Backup through CWM.
Used the ROM for a few days, but when I saw that official update is ready for download for i9020A, did do a restore from the Nandroid backup I created.
Updated from 2.3.3 to 2.3.4, phone works fantastic, video chat also works great.
After update when I tried using any of the apps required SU permission, they didn't work. I tried installing a couple of .apk files, couldn't either install it or after installation it didn't work.
Thought let me try wiping my phone clean and start all over again, may be I will use a custom ROM again, downloaded ROM, went to ROM Manager to reboot into recovery, nothing happens.
Tried booting into Recovery option manually by pressing Volume Up and Power button, nothing happens but the Bot with an Arrow appears on screen.
So, I thought I will follow this procedure to reflash CWM to my phone and get it going. I was able to use the command FastBoot once, and suceeded pushing .img file to my phone but now whenever I try using the commands from my computer, this error message appears : "This application has failed to start becasue AdbWinApi.dll was not found. Re-installing the application may fix this problem."
Why this error message if I have the sdk on my computer already through which I was once able to push .img file without any troubles?
Can anyone tell me what would be a possible solution?
Also, how can I fix this problem and get ClockWorkMod Recovery installed on my NS again?
How can I get stock recovery image on my phone if I want start all over again from scratch?
Thx a million.
Edit ::: I found the answer as to how to how to install CWM again. Thx anyways.
Other question still remains a puzzle... why am I not able to install certain programs or if did manage to install, can't run them?
I ran your method and I think I'm stuck at some step...
My phone now default boots into CWM 3.0.2.4
Recovery boots to a newer recovery I flashed.
How do I get my phone to default boot into the OS again?
Edit: nevermind, just downloaded the full 2.3.4 rom, extracted and flashed the original boot.img.

After installing the sdk and a platform, I have adb, but where is fastboot?
I was getting the same error as "Image cant be loaded". after hours of struggling I found that It's only because I was not in the same directory as the img file. silly eh?
hi,did you repaiar your phone,i have try everything but it just keep going in clockwork mode,if i than pres reboot now in clockworkmode it stays on google padlock
i realy need phone if you can help or someone else,than ....
just tried this method of window7 (thanks for the work) with cwm 3.0.2.4, but got the same result like the others in this thread: cant boot the android 2.3.4, the system is always booting into the cwm, no way out.
I don't think this tool works as it should.
:-(
EDIT:
I didn't realize that window7's tool would install the cwm into the boot-partition instead of the recovery-partition.
To get my boot partition back I downloaded the 2.3.4 firmware image from http://forum.xda-developers.com/showthread.php?t=1056062 and extracted the boot.img from the zip.
with "fastboot flash boot boot.img" I restored my orginal boot partition an can boot into android again.
(fastboot is part of the android sdk)

[Q] Did I brick my Nexus 4?

Hi,
Last night i was playing with my N4 (with some root applications) and an app asked for a reboot. I just pressed yes so that the phone will reboot (I have done this earlier without any issues). Suddenly the device doesn't boot up. My N4 is stuck at a black screen. While trying to boot up, the Google logo appears and then a black screen. It doesn't advance to the 'X' logo. I'm running on stock, rooted phone (used N4 toolkit by Wugfresh to root).
I'm able to boot into recovery although. I tried all the possible means, wiped cache, dalvik cache, did a factory reset, backed up the system and tried to restore the same. Nothing happened.
Then i tried the "Back to Stock" option in the N4 toolkit and chose the option "Soft-brick/Bootloop" to recover my N4. These are what happened:
Downloaded the 4.2.2 image from Google servers and tried to flash in the device with prior instruction from the toolkit. Everything went fine until the flashing process. In the last step the CMD window opens up saying it is unrooting and flashing stock and immediately it'll bring up a complete message saying the flashing is complete and to wait until the device boots up. But nothing happens again.
I tried the automatic flashing and on the downloading window it saying download failed and hash checks failed meaning its not downloading.
I searched all the possible threads in a day to find a similar problem but in vain. I'm not a noob but i'm too lazy . But i would do anything to bring my N4 back to life. Anyone please show me a direction.
In short:
Status: Soft-Bricked (guess so), black screen after Google logo
Version: Stock 4.2.2 (rooted+busybox+supersu+twrp)
Able to boot to recovering: Yes, bootable to recovery and bootloader.
Tried Nexus toolkit recovery: Yes but in vain.
Gave up: No and never, I'm searching and searching for answers and I'm worried if I'll end up in a hard brick. :crying:
Guys, please help.
Thank You!

I'm just taking a wild guess here - I'm not responsible if anything bad happens, and you might want to wait to someone else seconds my suggestion in any case (although I can't imagine things getting worse as long as you flash N4 stuff). But have you tried flashing a new boot.img/reset kernel from recovery or via fastboot/toolkit?

Err...nope I haven't tried any and will wait until someone seconds you. Meanwhile I have wiped off the ROM through the option in recovery. Still will I be able to do what you said? Also if could direct me to a "how-to" thread would be great. Just that I don't wanna mess up again.
Also, is there a way to transfer a ROM to N4 through fastboot? So that I can install the ROM through TWRP.

No, my suggestion would require that the ROM is still on the phone, so you should restore your ROM prior to my suggestion. And I'm by no means an expert (therefore the disclaimer), but I *think* that since it's a bootup problem, it could be solved by flashing a new boot.img (which is essentially flashing a new kernel to the system).
But yeah, let's see if others think this might help, haven't researched it, is at work right now. Just throwing in a suggestion, that's all...

I *think* (again, I'm totally not sure about this, as I haven't tried it) that you can sideload a ROM via zip file from recovery, but since I haven't tried it I'm not sure - can anybody confirm???
EDIT: Chromium's suggestion is better, by pushing the ROM.zip to the device and flashing from recovery (check md5 first, just in case).

Yes there is. Your nexus is not bricked and this is why you shouldnt use toolkits to do things. This is honestly an extremely easy and simple fix. Use adb to push a rom onto the n4.
Code:
adb push \path\to\rom.zip /sdcard
Boot into recovery, do a full wipe, and flash the rom.
You said you downloaded the Google images.
Just boot your phone into the bootloader and run the flashall.bat that is in the Google image folder.
Note this will probably fully wipe you're phone in the process

Okay, thanks guys. I'm on it. Will let you know when I'm done.
That same thing happened to me once. I had to extract the google file and look for the 4 img files(bootloader, system, userdata, recovery) and flash them with toolkit manually and it fixed it, but it erased everything on my sd
I tried to load the file "occam-jdq39-factory-345dc199.tar" into my phone using the ADB sideload feature in the toolkit. I don't have the SDK installed hence I depended the tool again. But now the tool only loads .zip file and not .tar as the one that i downloaded. Am I doing it right?

K if you have a custom recovery installed, there isnt much you need to do to fix the issue.
First setup adb/fastboot by reading this
Then boot the phone into recovery, and plug it into the computer. Open a new command prompt window and use adb like this:
Code:
adb push \path\to\rom.zip /sdcard
Then you can unplug the phone. From recovery go to the install menu, find the rom that you just pushed, and flash it.

[Q] No noob, Recovery problems.

So i got my brand new verizon Lg G2 Yesterday, straight from verizon. It came stock Running VS98012B, Build number JDQ39B, Android 4.2.2.
I ran it completely stock for a little bit, and loved it. But ima crack flasher, and cant run stock for long. So i decided to root. I Used ioroot24 With a few hiccups(ADB drivers wouldnt install with windows 7, So i had to boot into windows xp and do the process).
So im now running the same software with a completely functioning and full root. Next step was to install TWRP or Cwm(philz). I followed WACOmalts Guide.... with no success.
(http://forum.xda-developers.com/showthread.php?t=2449670) This one.
Option 1 Goes good until this step
"./loki_flash recovery /data/local/tmp/openrecovery-twrp-2.6.3.2-g2vzw.img"
It always says something failed (Not sure about the message Because i cant repeat it now) Or it gives me a list of commands, as if i typed "adb"
Option 2 I can follow completely through with no errors, But rebooting into recovery always brings me to a black screen.
Ive tried the 2.6.3.1 and the 2.6.3.2 .img files with so success. So i downloaded both 2.6.3.3 and 2.7.0.0 zips and extracted the recovery img and tried using those files. Still a black screen.
Option 3 Just dont work for me.

Just ran into the same issue it doesn't seem like anyone has an answer for this yet, some from this thread http://forum.xda-developers.com/showthread.php?t=2584052
said they were able to just flash back to stock and do everything over and it worked but I was looking into to that but the KDZ method is apparently broken at the time and for the TOT method to restore I can't find a VS98012B (latest VZ firmware so far) TOT file to use for the restore so I don't break anything else.
I'll see what I can find and let me know if you find anything :good:
try Flashify app from the store :good:
Ok so "s-chassis" so being as persistent as I am:laugh:, I was able to find the stock recovery for VS98012B in another thread you can download it here:
http://forum.xda-developers.com/sho...mctr=(not provided)&__utmv=-&__utmk=193184686
Look at post #10
Then I used the dd method to flash the recovery, here it is if you forgot
adb push recovery_vs98012b.img /data/local/tmp/recovery_vs98012b.img
adb shell
(IF YOU DONT SEE A # prompt, type su to get it.)
cd /data/local/tmp
dd if=/data/local/tmp/recovery_vs98012b.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
exit
adb reboot recovery
I got back to the stock recovery but the android has a red exclamation mark on it not sure why but if you have any ideas let me know

I'd recommend flashify to flash recovery images. You can download it from the play store. So easy to make a typo and mess things up with adb and dd.
You could do it with a terminal or adb shell. Say you store the image in /sdcard
Code:
su
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p14
Verify mmcblk0p14 is recovery before you try this. I'm pretty sure that's right, but I don't have my tablet right now and you can make a serious mess of your device this way if you overwrite the wrong partition. Check it by listing your partitions with this:
Code:
su
ls -al /dev/block/platform/*/by-name
By default this little tablet does not have fastboot, but you can enable it with this method. I've zeroed out my laf partition and verified I can boot into fastboot mode, but I've never actually used it to flash anything. It just seemed like a good idea to have fastboot available to fall back on rather than LG download mode since there was no kdz available for the V410 for a long time.

I'd recommend flashify to flash recovery images. You can download it from the play store. So easy to make a typo and mess things up with adb and dd.
You could do it with a terminal or adb shell. Say you store the image in /sdcard
Code:
su
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p14

Thank you! the thing is i bricked my g pad, i really dont know much about the tab because the lack of support it has. I was using it with cm12.1 and i use a stock recovery founded in Android central to revert back to stock, but in TWRP i flashed the img as recovery and also as boot, so the g pad entered in a bootloop were only enters in stock recovery, my Windows 10 laptop doesn't recognize the tab when in adb sideload, and doesn't know much about adb Shell, i'm following the comandas you wrote but i'm always getting error: closed.
i know how to get back to stock using the kdz, but using the kdz will make the partition issue and will have to folllow a looong looong process.
If you could give me a hand with this i would really apprecciate it
Sorry I've never encountered the adb closed problem myself, but I have heard about it before. Some people have reported the following series of commands fixes it:
Code:
adb usb
adb devices
adb kill-server
adb start-server
The first two commands normally don't really do anything and its pretty obvious what the second two do, but some people have reported success doing this.
Some people have reported the closed error was fixed by updating their adb binary. If you're using the android-sdk update platform-tools, or if you're using a standalone adb consider looking for an update for it.
Good luck. That procedure to get things back to normal following using the kdz to restore sounds messy.

here's a link to an image I made before flashing twrp on my v410. I've restored it with dd and flashify and it works fine. https://docs.google.com/file/d/0B1l3W9XHAqEgX0ZCUWc1QTlfWjg/edit?usp=docslist_api

I flashed stock rooted 4.4.2, and I want to OTA to Stock Lollipop, but it says there is no update. Any ideas of how I can get back to fully stock? Would flashing this stock recovery make it work? Is being rooted blocking the OTA update from seeing an available update?

If you applied an OTA with a custom recovery installed it might soft brick your tablet, but I don't see why that would stop it from detecting and downloading the update. It is always safest to flash stock recovery, fully unroot, and undo any modifications you've made to /system before taking an OTA, but some devices are more picky than others. With what you're describing I'm afraid that even if you do unroot and flash stock recovery your tablet still won't find the OTA.
Do you have a nandroid backup of an unmodified stock ROM you could restore?
And just so you know that lollipop bootloader is not vulnerable to the bump exploit, so no custom recovery or ROMs if you get it to apply.
Whenever I type "reboot recovery" in terminal emulator, it boots straight to factory reset. I have tried this multiple times with both dd and flashify. Do you know what causes this? I'm downloading the OTA right now, I hope it doesn't wipe then too...
please help
i was a dumbass and accidently flashed my boot instead of recovery do you by chance have a boot.img that i can use to reflash my boot.img please help as im really stuck..thanks in advance

Download the timmytim stock ROM, and extract the boot.img from it. There are probably quicker ways, but having the stock ROM on hand is a good idea.

Thank you...
I resolved my issue i had forgotten in my haste i posted the same question in two different sections. However after fixing everything my tablet was broke not the out glass but the inner display. I cant afford another one or a replacement part to even fix mine. So unless i can find one someone who bricked theirs completely or get a handme down im tabless for awhile.... Thank you though for the reply. The original boot file wouldnt work properly i had to use the boot file from the stock rooted rom and not the timmytim deoxedized rom.. i dont know why unless the bootfile is specific to each rom. Maybe i did something wromg during the flash. But i had gotten it fixed nevertheless.

The stock rooted is by timmytim ?
I forgot about deodexed, actually.
Glad you fixed boot, shame your tablet broke ?

[How to] Unbrick v410

I posted this in the original DEV discussion and I also posted it as a reply to some people with the question. I'm only making this thread to save people from searching through hundreds and hundreds of posts. As you may know there is no kdz or tot for the v410 gpad. Without any clue as to why I woke up and my v410 was in twrp, tried a restore, a wipe, installing custom roms, each time it would say it was successful yet each time it would just boot right back into TWRP. Then i stumbled across a thread made by "Thecubed" in 2013 that had nothing to do with this device, it was a thread about being stuck in TWRP after OTA, so I thought id give it a shot and it worked like a charm 8) here are my instructions
1. if you dont have adb setup adb you can get a minimal adb here
https://www.androidfilehost.com/?fid=385035244224386526
install it, navigate to program files (Or if your on a 64bit system program files(x86)
Right click and click "Open command window here"
2. plug in your device if it isnt already pluged in, and type the following commands pressing ENTER after each line
DO NOT COPY PASTE THE WHOLE THING EACH LINE MUST BE PRESSED ENTERED separately
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
exit
adb reboot
Your phone should boot into your rom now
You can hit thanks for my effort of days of searching and you can also thank the dev of the thread that I got these instructions from "thecubed" here at this link http://forum.xda-developers.com/show....php?t=2451696 Hope this helps someone
Saved my ass tonight! Thanks bud!!
I'm stuck in your boat as well, only booting to twrp. The google docs link dead... but I was able to find the minimal adb. I haven't been able to get a working v410 driver though. Any ideas? I'm on Win10, so perhaps that's my problem.
Edit: I tried another v410 and my pc recognized it, so it's something to do with this tab being stuck in twrp and not getting recognized. if that helps.
I'm in the same boat, nothing I have tried, including the steps listed here seems to work.
If you check the first page of the link majicmazo provided, there are instructions for using the TWRP terminal command, which will start the process of getting it out of its current state.

Both links are broken, which is a special feat given the post is only 4 months old and edited on 8/26. Anyway the link you mentioned is correctly posted here: http://forum.xda-developers.com/showthread.php?t=2451696
However, if like me, your device cannot be recognized in Windows, and you're stuck in TWRP, you should run try and run the following command while in TWRP by clicking "Advance" then "Terminal Command" and "Select"
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
The command should run, then tap the return button until you're back to the main screen. Reboot without installing SuperSU.
I have 6 v410 devices with nearly exact same setups. I say nearly, because there must be something different that I'm not aware of. 4 out of 6 updated fine, 2 were bricked. 1 had to be sent to LG for warranty replacement. Go figure.
"I have 6 v410 devices with nearly exact same setups."
Good day, Sir! I have v410 and accidentally bricked it when I tried to change something in build.prop. I have no recovery installed. Nothing at all. The only change I did is the root and I cannot flash it due to some errors. A friend of mine told me I should find back up of other good v410 (.tot file if I'm not mistaken) and it could be applied to my bricked v410. Will it work? What method should be used for the .tot file? Are there anyway I could unbrick it without returning it to service centre? I have no warranty since I bought it abroad. I'm looking forward for your answers. Thank you!
I also have a stock recovery image if anyone needs it. Performing the above steps while in twrp will allow you to reboot back into device, but any updates from ATT will cause the device to brick back to TWRP.
If you flash the stock recovery here using flashify,: https://drive.google.com/open?id=0B9ztRll4cXJyTWktNXJLU2VDLU0, you will be able to install the ATTT updates without softbricking into twrp.

Here is the v410 stock recovery: https://drive.google.com/open?id=0B9ztRll4cXJyTWktNXJLU2VDLU0
It worked for me but your mileage may vary. I'm not responsible for any issues.
Thank you, kind sir! I'll inform you if it does worked. :good:
Unfortunately, it didn't work. Perhaps you have v410 stock rom I can flash using lg flash tool?
V410 KDZ or stock recovery request.

Hello,
I have been flashing v410 lately and I have been unable to find a STOCK v410 kdz anywhere.
A stock recovery file would be great!. However, the one one at the above url looks pretty small (at 13MB) or am I missing something?

That file is just the recovery partition, not a whole system image.
To the best of my knowledge there has been no kdz released for the V410. Thank your carrier for that, because LG provides it for the V400.
please help my when i command adb shell have error device not found i have Qualcomm HS-USB QDLoader 9008 mode on lg gpad v410 ((
Alright this post is almost a year old...But i still went back and updated the Minimul ADB link, the second link on my post is simply a thanks to the original person, yes it was deleted theres nothing I can do but you guys do not need it it was only there for you guys to say thanks to him. This thread is only the solution to being stuck in TWRP, some people here asked me for the stock rom,At the time i wrote this thread no one had a kdz for the v410 however now there in fact is one, its android 4.4.2 http://www.mediafire.com/file/2433xqabj1k8b8d/V41007h_0.kdz and I found it here https://forum.xda-developers.com/g-pad-10/general/unbrick-v410-t3105091. Probably easier then my thread to simply flash this with the flash tools but If you decide to follow my old outdated method, and follow the steps %100 it should theoretly get you out of the TWRP bootloop, it worked for me and I was simply sharing, However if it doest work for you dont bite my head off, there are many reasons why you might be in a boot-loop and many factors that come into play so My solution might not be the best for you. Anyway I dont know why I'm reviving an almost year old thread but I just never read the responses as I havent been on XDA for a while and figured I would post in case anyone still wanted it. Again there is a much easier way now because there is a KDZ so this is outdated.
