[Q] Help! - Rooted Zenfone 2 (ZE551ML) bricked after OTA accidently

followed a tutorial (Cnncted's youtube clip - How to root the ASUS ZenFone 2 ) to root
Accidentally (very stupid) pressed the update option when an OTA update showed up yesterday (Jul 8 2015), and after that the phone won't start properly - stopped at in search of incredible...
No luck with trying to boot into recovery mode (power + volume up). It just vibrates once and the screen is black. Trying to flash recovery image with ADB and flashtool etc, but the MTP usb connection failed. If I connect it to the PC using the USB cable and then press the power button to turn it on (stuck in that ..."incredible" screen), device manager shows the Z200AD name with a yellow exclamation mark beside, and Asus ZenUI software will automatically start. But it's not really recognized by the PC.
So...if you have any suggestions for me to try, please let me know and that would be greatly appreciated!

p.s. This is a US version, so the it's the WW sku?

Same problem here. I have a rooted 551ML and on July 6th I received an OTA update. I installed it and I'm stuck in boot loop. I have hundreds of family pictures in the internal memory.
The good news is that I have access to boot loader and recovery.
I could not find any custom recovery for Zenfone 2. They are not out yet, right? Is there any way to copy the internal memory of the phone (that doesnt load the OS) to the SD card? Or to paste a file img.boot taken from a downloaded official rom and copy it over the corrupted one on the phone's memory?

If you can access the bootloader, you can do this:
http://forum.xda-developers.com/zenfone2/general/guide-to-apply-ota-bootloop-rooted-zf2-t3127835
Btw, there is a custom recovery out there (TWRP, check the Development section), but you will need an unlocked bootloader to use it in your state (I think).
US version is the WW SKU btw. Hope this helps.

Joel, thanks a lot! I will give it a try.
fingers and toes crossed...

I faced this problem too. All I did was to flash the boot.img of my version using fastboot,
Then I flashed the firmware, without factory reset I started the phone.
I was continiously getting an error "com.android.process has stopped". Ignoring that, I just backed up my whole data. Did a factory reset. Updated
Boom!! Everything was normal... I hope this helps

Just a quick update - followed the method in the link that Joel referred to, and everything worked beautifully. I did get two error messages like “the contact stopped working..." “The process android.process.acore has stopped working.” I fixed this problem by clearing the data/cache from the "contact" app, and that did the trick without a factory reset etc.
I unrooted the device using SuperSU. The fastboot screen, however, still shows a random serial number 0123456789ABCDEF. Is there a way to revert it back to the real one? I do see the real one from settings - about - status.

Isn't everyone serial number the same? mine is.

This is something that I am not sure of. Yours has been rooted as well?
I would like to know what the fastboot screen looks like before rooting.

Pretty sure rooting didn't affect my fastboot screen at all.

actually i rooted my zenfone 2 and there was an OTA and i tried to install it without un-rooting my phone. the phone would not turn on and it gets stuck in the boot animation.
the phone wasn't detected by the ADB in my pc so i thought of installing some custom recovery, thought that could help.
i tried installing TWRP but i did not unlock the bootloader and now i am not able to enter in recovery mode either, everytime i try to get in the recovery modethe phone restarts and goes to fastboot mode.
please help.

I was having a similar issue where adb wouldn't recognize my phone but fastboot was detecting it. What I ended up doing was grabbing the latest stock firmware zip from asus, transferring it to my external sd card via adapter and renamed it to MOFD_SDUPDATE.zip. Then go into fastboot (restart with volume up key) and proceed to recovery. It should automatically update your system from there. The only bummer is having to re-configure everything.

LG G3 Stuck In Bootloop

Hi XDA, many threads here have helped me in the past so time to ask another (probably stupid) question. It's a bit of a long story so I apologise in advance.
I've been running CM (one of the nightly builds from about 3 weeks back, don't have the file so I can't say which) on my phone for a while with no issues until a couple of nights ago when it was overheating (charging while playing a game, stupid I know) so I decided to turn it off so it could cool down without taking it off charge.
The following morning I turn it back on to find that it's getting to the blue android head logo of CM and getting stuck there. First thing I do is reboot into TWRP and flash my backup from right after I installed CM. Reboot and... same result. Okay, no biggie right? Time to reinstall CM (the latest nightly build from yesterday) and Google Apps (nano package) via TWRP and reboot again. Still stuck at the blue android head logo. The reinstall was handled after using the Wipe-Factory Reset function of TWRP, as the guide here explains.
At this point I decide to do a bit of research and learn that it's called a softbrick or bootloop and apparently flashing the stock rom can fix it. The LG software suite won't even recognise the device but a friend of mine found this guide so I attempted to run through it. All goes well until it comes time for the software to connect to the phone - I pop it in download mode while putting the USB cable in, the program says waiting for connection, runs for 14 seconds and says it's trying to put the phone into download mode, at this point it fails saying the phone can't be put into download mode.
Some of the comments beneath the article offer fixes like using USB 2.0 instead of 3.0, putting the program into compatability mode for Win7 and running in administrator mode. To be thorough I tried every USB port on my machine (both 2.0 and 3.0) and run the program in compatability mode (with and without admin mode) for several versions of windows. Same result every time.
Another friend then suggests that somehow permissions got borked and it might be worth reflashing SuperSU to the system but at this point I'm at a loss for how to do that. I have the one click root script that I got from god knows where (not this one because that didn't work for me) that has a SuperSU zip in it, presumably it flashes that to the phone when it runs (found this out the hard way because I've been a moron in the past and tried installing SuperSU through TWRP and broke the boot previously, fixed by re-running the one click root script - this was ages ago before even installing CM.)
So right now I can put the phone into download mode manually, get into TWRP and use all its functions as well as connect to my PC and use ADB functions while the phone's in TWRP but can't boot into CM or flash a stock rom. Any help would be appreciated, I've spent a whole day reading guides, asking friends and clumsily trying to fix this only to get nowhere.

Have u tried installing the stock via TWRP? Via zip ... Wipe cache delvik also..

I haven't tried that, I didn't even know it was possible. Could you give me some more detailed pointers on how to do this? I noticed that the stock ROM I have cames as a .TOT file but CM is several files and folders in the zip. Will it install fine from that zipped up TOT file?
Thank you so much for your time.

When the rom is uploaded by the dev its also uploaded in .zip file place it ur system rom just go into twrp recovery flash the the zip file before flashing wipe cache n delvik too its easy as 1,2,3 search here on xda for ur compatible model

Today's CM14 bricked my H815 (no bootloader, no fastboot, no recovery)

Hi,
My H815 always suffered from this problem: http://forum.xda-developers.com/g4/help/fastboot-download-mode-problem-t3466649 - the only way I could have fastboot was from an adb shell.
Well, that was not a problem until today: CM14's nightly broke (booting just loops at the moving logo) and now I have no way to go back to fastboot. And if I try the recovery mode, I just have a blurry circle saying "erasing" for a few seconds, then a looping CM logo.
Anyone has a way out of this mess ?

When you say you try the recovery mode how do you try to get into it? Btw do you have twrp installed?

Same thing happened to me, tried to install, just got put straight back in to TWRP after boot. Tried installing a stock ROM, CM ROM & using LG Bridge to recover, to no avail. Help appreciated, (i'm assuming LGUP is going to come up a lot)

Sorry, it's nearly the same issue though, CM14.1 broke phones today.

Today's update broke mine as well. Looking for solutions. Will follow your thread and progress.

Same for me. Tried download mode with lgup to flash stock which worked once - but I kind of bricked it again by trying to install cm14.1 again. Then i tried to go back to stock using lgup again, but now lgup it just crashes. The phone now goes automatically to download mode after turning it on, the progress bar stays at 0%, the phone says "633A B100" and lgup crashes after 9% "prepare dlmode" or something similar. any ideas? :/

Some people seem to have fixed this issue by flashing the official Cyanogenmod Recovery.

After flashig the CM Recovery via TWRP, i can't use the recovery anymore. If i boot into CM-Recovery the display shows "Ereasing" and start the system. After that i got a bootloop.
Is it possible to use fastboot??

You guys should also check CM14.1 thread because people there are talking about the same problem. The latest post says the only solution was to flash an official kdz with LGUP.

Did that. Worked once. Then i tried to flash cm again and had the same problems, so i wanted to flash stock again... now lgup crashes at 9% and the phones goes directly to download mode after turning it on.

And the two times you tried to flash CM, that was with the same recovery ?
Can you go into fastboot mode ?

Yes, it was with cm recovery 20161130, if i remember correctly.
Sadly now, i can not go into fastboot. The phone goes directly into download mode. My windows vm detects the phone, and tries to flash a recent kdz, but lgup crashes at 9%. The phone still shows "0%".

Oh that's bad. What about another kdz ?

Already tried like 3-4.... Its always the same. If the tool would at least give me a little bit more information, but it just stops.

I don't know then. Some users seem to have had the same problem (stuck at 9%) : http://forum.xda-developers.com/search/forum/4233?query=lgup 9%

I had the same issue, tried several things, my final solution was:
- Start in download mode (Volumen up and then plug in cable)
- use "LG Brigde" on Mac to install stock Rom ( Software update tab in APP ) guess should also work with Windows
- Boot original android
- enable usb debug
- Start bootloader via ADB
- fastboot flash recovery to twrp 3.0.2
- Boot in recovery via power and vol down (first factory reset from stock appears but after this twrp is starting)
- install cm nighty of 1 DEC via ADB sideload
- reboot and done
In the meantime i updated to twrp 3.0.2-1., installed gapps etc. everything is now working fine again.
Hope this is also working for you.

Which version of cm14 did u download and install? Can u please post the exact version?

Mmh ... LGUP is the Windows utility right ? How do I do if I only have a Linux machine ?

I'm trying to get to it via power+down, I get to the double "do you want to factory reset ?" question, but then :
- sometimes the CM recovery just says "erasing" for a few seconds and reboots to (non-working) CM
- sometimes it just plainly boots to (non-working) CM
I used to have TWRP installed but it didn't work with CM update, so I let CM install its own recovery.

[Q] Bricked Gpad 8.3 - stock rom via LG Flash Tool not working

So. Recently, I got CyanogenMod 13 on my Gpad. Everything was just fine. Then I installed the Magisk Manager, which, for some reason, disabled the root access on the device. When I uninstalled it, my recovery (TWRP) asked me, if I want to install SuperSU. I selected yes. And that's the moment when everything fcked up. After SuperSU installation, my tablet went into bootloop, and I wasnt't even able to enter recovery via button combination. I tried to flash the stock rom via LG Flash Tool, but failed miserably. I tried multiple stock roms, but the result is till the same: I can't access the Factory Reset via buttons, the system keeps rebooting, and even if it boots for few seconds, the touchscreen isn't responding. I even tried connecting mouse via USB otg, but no success. Is my tablet dead? Is there any chance of repairing it?
Thank you for your help.
EDIT: It's v500 European version.

nope, it's not death (yet)... The buttoncombo to enter might be a problem, but keep trying. If really nothing goes, try connecting to your PC and open a commandline. Type : adb reboot recovery (preferably from a linuxbox). However, make sure you got a ROM, GApps and SU system 2.78 or 2.79 ready on the SD. Personally I recommend @adrianom AOSP 7.1.1, OpenGApps micro and SU 2.79 SR2'systemmode.

Thank you for your reply.
However:
I am not able to stay in the system.
I am not able to enter the recovery. (because of the brick)
I am not able to enter ADB, because there's just no way how. I have USB debugging disabled by default (because I tried to reset the system using LG Flash Tool) and I can't use ADB in the download mode.
Actually, download mode is the only thing that hasn't broke yet. I still hope that someone that has experienced similar problems help me.
But again, thanks for your (and the only) reply.

If you can get into download, you could connect to a PC and start the LG-tools.Use that to restore to the original ROM and start allover again with latedt software (TWRP, ROM, SU)

S10e - impossibility to install Lineage OS

I need to install Lineage OS on this phone.
After multiple tries several months apart, I am still not in success.
Followed all internet tutorials and sites.
I don't want to install any G apps or any special root-things like magdisk..
I only want pure Lineage OS without any extra applications.
Way I tried and probably ended up like before:
Get newest official samsung ROM installed, update, enable usb debigging and oem, go download mode and go factory reset, get back in, sign in to wifi again, again enable develop. settings and usb debugging, go into download mode, take odin and install through the AP option the TWRP now that the phone is in download mode a 3rd time, supposed to be possible now with OEM unlock.
Most of the names on the way I don't understand, just follow tutorials.
I need to get to TWRP to then finally, as used to always, install Lineage from zip.
But I never get rebooted into TWRP recovery, just forver the samsung one, even when firmware is no longer there - after flashing in ap option the twrp tar again it never boots into TWRP afterwards.
Is there something else i must do? is not getting into oem unlock and flashing TWRP enough to get there?
And after, will the zip install finaly get me to have lineage installed?

Did you try the official guide?
https://wiki.lineageos.org/devices/beyond0lte/
I hope I picked the right phones, otherwise check devices overview.
Alternatively, perhaps this helps:
https://forum.xda-developers.com/t/...-a-graphical-installer-for-lineageos.4509995/
PS: Usually LOS doesn't do TWRP anymore but comes with its own recovery (a/b)

Why they don't do TWRP now?
I saw TWRP tuorial fot s10 on tutorials and it worked
Do I have to give up on TWRP way and od it with the adb commands from PC

Yes, it's still there but perhaps you post a link to your guide (or ask there). To me it seems you had TWRP just in your RAM but not your phone?
As for me, I finally gave up on TWRP and use the "crappy" LOS recovery Have way more important things to waste my time on...
PS: Sorry to bring such "bad" news, wasn't too happy with that change myself

Great, I finaly made it work.
I followed the site with turotial on installation and did not try TWRP
First I had to install samsung ROM again
It turned out to still stay unlocked so went straight to download mode and this time flashed Lineage recovery sucesfuly with heimdall
Then it booted up and a half samsung sreen made it seem like there is trouble
but Lineage recovery launched
The adb load from PC did not work so i chose to instal zip from SD even there
Now Lineage is installed
Still don't know how much is randomness, luck and so on
But it's done and hopefuly repeatable
