Zenfone 2 ZE551ML not booting up

Please help, I've made the mistake of applying the marshmallow update file, while using the TWRP recovery. It was stuck on writing splashscreen, for around 2hrs. I thought about restarting the device to restore a previous backup image. That is when the screen turned off for good. No matter what i tried, I could not boot into recovery, or even fastboot. I've tried the key combinations, adb, but nothing seems to bring this up to life. Please tell me how to flash the stock zip, I don't care about the data in the phone at this point.

You probably have the same problem I have. Fixed it with this http://forum.xda-developers.com/zenfone2/help/thead-bricked-phone-updating-to-mm-tips-t3452785

I did have the same issue,Thank you. But in the later steps, when the phone boots into fastboot, I cannot use any flash commands. It always shows FAILED (remote: flash_cmds error!). Any ideas?

Can you boot into recovery now? after doing those steps I still had twrp installed and used the recovery.img from the stock rom and then booted back to stock recovery and applied update via adb

It did work after another xFSTK download, don't know why the error was caused in the first place. Flashed TWRP and restored a previous backup.

Bootloops when flashing System, Data

It first started this morning when my phone suddenly started rebooting while I was using it. Then I thought it as a ROM issue and flashed a new ROM over it. Everytime I try to flash something on system. TWRP Hangs and the phone restarts itself.
Tried repairing data, system partitions from TWRP, same thing happens. Bootloops when I try to repair data partition
Tried restoring nandroid backup. When it says flashing data, TWRP freezes and the phone starts bootlooping.
Can anyone help?

I have tried doing the EFS flash via adb from PC.

I'm stuck with the exact same problem since months.

Have you tried Claiming Warranty?

try doing a re flash of recovery, because your issue will be to get your recovery working properly or else you cant remount anything else.

I flashed TWRP 3.0.2,3.0.2-2,3.0.2-3
Loads of it. Tried doing full stock + unroot from Nexus toolkit. That usually fixed all my problems Everytime I was in dire problems like this.

I've never used that toolkit. Since day 1, ive used skipsoft android toolkit. just keep on trying. Does it crash at all when doing backups?

Well in your case what I would do is a backup,
Then wipe, flash custom rom. Use phone til reboot.
If reboot, flash stock IMG. Use till reboot
If still rebooting, then come back. I guess I never asked.what rom.your using

It bootloops

I have the exact same problem. Last week upgraded to 7.0, root, stock room, viper4arise audio and EX kernel and that's it. while taking pictures it froze then that boot loop, somehow I managed through a combination of flashing factory image through fastboot, locking, unlocking, reflahsing, to get it to boot normally, then yesterday I was taking pictures again and it refroze then bootloops. Now I am able to fastboot factory images but it doesn't get me out of the bootloops, and in TRWP same as you, I cannot flash anything on data or system. Repairing the file system doesn'T change anything, I did like on other threads also and flashed factury, restored nandroid then flash factory but the restore on TRWP always hangs up.
I was wondering if there is someone knowing the adb dd commands to impose the raw copying back of the restore ? Maybe that would work.

Did you try wiping system under wipe > advanced in TWRP?

In twrp, can you open a terminal and check the results of this (basically, doing a full read-only test of your flash)
Code:
dd if=/dev/block/mmcblk0 of=/dev/null

Cant get out of TWRP

So i just did the new update on my V20 and it sent me straight to TWRP and i cant get out of it. It always boots into TWRP. What can i do? ive already tried a factory reset and restoring my back up and nada. Help please.

Its now looking for stock boot image which on yours is currently modified with system rooted.
Try using lgbridge to repairs your boot image or if you have it flash the stock boot image using fast boot command or do a factory reset while in twrp then flash entire stock image with lgbridge.

Yeah none of those work. The OS is setting off some sort of flag that states it must go into recovery and wont stop going into recovery until that flag is changed which I assume is done by the update. I tried updating with UPPERCUT/LGUP and it errors out at 4%. So right now it's still stuck

It didnt install the update
type
Code:
fastboot erase fota
from bootloader and see if it boots after that.

This will for sure fix you up...
https://forum.xda-developers.com/v20/how-to/how-fixed-bricked-lg-v20-t3501310

listen to me2151
delete fota and then pull battery and reboot.
ota's downloaded to the fota folder will cause endless twrp loop.
freeze ota in system/privapps to avoid this again.

Sorry to post on here, but maybe we can get a few tips from each other.
Im also stuck at TWRP. I installed a ROM and went back and forth between both ROMS. After about 4 times of going back and forth between ROMS, my pattern didn't recognize on boot with my original backup and daily. I tried my pattern over 10 times and it wiped everything on me. The strange part was I was swiping my pattern 100% and it failed. Also, my tries were going up and down. It would say I have 6 tries left before my phone wipes, then I would stop anjd turn the screen off, and the screen would say I have 3 tries left, then 5 tries left. My tries were inconsistent, and it finally wiped everything.
I am now stuck on TWRP with no luck of restoring. I flashed the vs995 boot image and system image and it goes back to TWRP. I factory reset, wiped everything, made sure the system folder was clean, then flashed both images again and the same thing, no luck.
I also tried to restore with LGUP, but keeps stopping at 9%. I extracted the dll and copied it into the common folder and I get the same thing.
Error: Error Code = 0x2000, Flashing Fail
When I plug the phone into my computer it shows us996 and not vs995. Strange.
Any help would be amazing.
EDIT: Figured it out!
So, I extracted the dll file from the kdz file and I had to replace it with the one in the common folder. My error was not renaming the file, so the LGUP would stop at 9%. Make sure you pull the file, rename it, remove the old file from the folder, and flash on LGUP.

Need Help; My LG G6 (H870) keeps booting in TWRP and I can't install stock ROM

Hi,
I unlocked the bootloader of my H870, installed TWRP 3.1.1.0 and SUPERSU. Everything was working great untill I decided to restore my system defaults to make a fresh start with my G6. After choosing the option to restore system defaults, my phone rebooted and it booted into TWRP. I rebooted my phone and it kept doing this all the time.
I decided to look for a stock ROM and flash that ROM.
I succesfully flashed the "LG-H87010f-Flashable.COMPLETE.zip" ROM (from autoprime's post) trough TWRP. But this did not work. I even wiped all the data from my phone (even system) and flashed the ROM again; still nothing.
Before having this issue, I had the same Baseband version, Kernel version, Build number. Only the dates and the Software Version are different.
I had the V10b-EUR-XX Software Version installed on my phone. I see this is the 10f version. I guess this should not be a problem right?
After this I took these steps solve this issue:
1. Downloaded new LG Mobile Drivers (LGMobileDriver_WHQL_Ver_4.2.0)
2. Downloaded and installed LGUP. LGUP doesnt recognize my phone as a LG G6 and this method did not work for that reason.
Fastboot mode is working on my phone; I can reboot my phone trough the commandline on my PC and things like that . However, my PC is not recognizing my phone as a LG G6 device in Fastboot mode.
My PC recognices my phone as a H870 when in TWRP. In Fastboot mode it recognices my phone as Android Device.
3. Installed LG Bridge for more drivers; did not work either
4. Downloaded Uppercut, but it doenst work without LGUP.
4. Looked all over the internet to find a Stock ROM in .zip or .img format; found nothing
5. Downloaded WindowsLGFirmwareExtract-1.2.6.1 and tried to extract the H87010d_00_OPEN_EU_OP_0327.kdz file. I extracted it into .bin files, but they were not usable. After that, I combined these .bin files into a system.img file. But that .img file was bigger then 5 GB and for that reason it was not usable to flash trough Fastboot or TWRP.
7. Looked for other methods to obtain a H870 Stock Rom, including another extraction method, but I cant figure out how to do this.
I have spend countless hours on this problem, but I cant find an usable H870 stock rom to flash my phone with.
Is there someone that can help me out with this problem? Im willing to donate some € if someone helps me to get my phone working again.
Really hoping for a kind person to help me out and provide me solution for this issue.
Thanks in advance

Try formating data in TWRP(not factory reset) then flash the 10f complete zip. Trying to perform a factory reset from within Android could have possibly messed up your data (due to TWRP being installed instead of stock recovery) so a full data format is needed.
Lgup most likely doesn't detect the phone because you wiped system. But flashing the complete zip should have restored system.
In the future make backups in TWRP to restore later.. or flash a kdz with lg bridge or lgup without wiping system first.

Thanks for your reply. I have already formatted data in TWRP, but im still having this problem . It seems like something is preventing my device from starting up. I have flashed several ROMS on other devices, but never experienced something like this. Is there something else I can try? Can I flash the stock recovery and flash the stock ROM? I got the feeling TWRP is causing this issue.
If its possible to flash stock recovery, where can I find it?

Flash the complete zip then boot into download mode and flash kdz. Lgup should see the device as a g6 now instead of unknown device. If lgup isn't seeing any device at all (including unknown device) then your setup is off.. missing drivers or something. If that doesn't work.. idk.

Don't factory reset using the in phone option. You can only do this through twrp's option. To fix this you'll need to boot through the hard side, using power and volume down until the lg logo appears then release power for 1 sec and then repress keeping volume down pressed. Confirm yes twice on the white screens to get to twrp. Once in twrp then reset again and reflash the system. Then using twrps img installer flash your twrp img(make sure it is on ext sd) again. Then reboot.

Probably because you already did all the flashing prior to. Glad it worked. This happened when I first got my V20 and was stoned not thinking. I reset using the in phone option and it caused twrp bootloop. I too learned the hard way.

Had the same issue, fixed it, thanks.

My phone kept doing this booting into recovery no mattery what ROM I installed.
I got into twrp by holding volume down and selecting yes on next 2 white screens....but now this message appears all the time.

Great tip @Swizzle82! It allowed me to restore my LG G6 after bootloop. It had not been detected by PC, and this hardware reset helped!

Hi, all
If I understand, and to sum up :
I rooted my LG-G6 few weeks ago, and intall TWRP. When OTA wants to install official update, the reboot stops in TWRP mod, so ... failed :-/
Is the solution to flash through Uppercut/LGUP with a .kdz file, without risk of brick the phone ?
Thx

How to root on stock 7.1.1 using Magisk

So I installed TWRP recovery using tuliptool and all that, but didn't bother with bootloader unlocking since it said it's not needed. So I tried to install Magisk using the instructions on their thread but after booting it asks me to reset my phone because the data got corrupted.
Luckily I had backed everything up beforehand, so I restored boot image and everything works fine again. Just wanted to know what I did wrong here. Did I miss any steps?

You probably didn't miss anything if it's the "Your device is corrupt. It can’t be trusted and may not work properly” error, I get the same thing. You messed with the files in the boot partition so ZTE's "safety" features in the stock ROM automatically call them corrupted. I simply hit the power button and continue to boot, my device works fine (actually much better than before being rooted with Magisk). I'm the one who "corrupted" the phone on purpose, so I'm comfortable it's fine. If you're getting another message, I'm not entirely sure why. Maybe try ADB sideloading Magisk in TWRP, it's what "worked" for me.

What do you mean by "hitting the power button and continue to boot"? When I hit the power button on the "Decryption unsuccessful" screen it just locks and unlocks like normal, but stays there.

Ok I managed to install Magisk after factory reset, but after that my sdcard is not being recognized anymore (but is recognizable in TWRP). So I decided to restore the backup i had, and rebooted. But now I'm stuck on the ZTE logo during boot. I can still open TWRP, though. I've tried wiping system, data, and cache, then restoring the backup, also no good. For now I'm downloading the stock firmware and will try that. Any ideas on how I can fix this before I flash the stock firmware?
EDIT: Ok I managed to fix it by installing the no verity boot image instead. Boots again. I'll probably refrain from trying to root for now. Thanks for the help.

Well, I wasn't much help, but it sounds like your overall problem was different than mine. My only advice is if you attempt to root with Magisk again, is to connect to your PC/Mac/etc with a cable, use the Advanced menu in TWRP, choose ADB sideload, and sideload Magisk from your PC/Mac/etc. You can find a more advanced explanations on various websites how to use ADB if you don't already know how. For some reason that worked for me and gave me full Magisk and phone functionality when nothing else did.

I didn't have to, but I can't guarantee it will work for you. I had previously factory reset my phone but at the time I sideloaded Magisk I had been using the phone for at least a week. Just make a backup of everything first to be safe. *edit* I am using the beta version of Magisk (16.4), not sure if that's making a difference.
