[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.

Interrupted flashing during "VolumeUp + Power" mode

I have updated my Nexus 5x to 7.1.1 beta and after a day it powered off and I got the infamous red led during charging. I was not able to turn the phone on even after leaving the charger on for some days. I thought it is bricked and left it alone connected to my computer.
However today, out of nowhere Google logo popped up. It was bootlooping, but I was able to enter bootloader and original recovery. I wanted to flash it from bootloader, but was unable, because it was still oem locked. And I was not able to oem unlock, because I did not do the required part in the Developer Tools menu. I tried to adb sideload OTA in the original recovery, but sideloading stopped after uploading ~48% every time.
So I opted for the "VolumeUp + Power" mode flashing. Phone was recognized and I started flashing the appropriate TOT file. However at 33% on phone and 28% on the PC, progress stopped. And after a minute or so phone turned off. Currently it has no signs of life at all. Have I completely bricked it now? Is there a way to recover from interrupted "VolumeUp + Power" flashing mode?
EDIT: at first I though maybe the battery died during flashing. But interruption was not abrupt. First the progress slowed down to halt. And then after some time phone turned off.

It seems not all is lost. Have a blinking red light again after leaving it connected to computer for a day. Back to square one, but at least it is alive.

Your motherboard is dead.
And it is not your fault, mine also died while using beta 7.1 and I sent it RMA. They replaced for a new one.
But in my case i had unlocked bootloader, I flashed back 7.0 and it gave no results, still bootloop that's why I sent

Thanks for the info.
After leaving my phone with a clamp on a power button throughout the night (so the red light would flash continuously), I got it booting into "VolumeUp + Power" mode and this time I have successfully flashed the same TOT file via LGUp software. It was still bootlooping after flashing. Now I was able to enter into bootloader and recovery and this time sideloading the same previous file actually works. However it still bootloops.
Anyway, I tried to RMA it and after giving my IMEI to the Google rep, they said that they could not find it in their system after checking US and UK store records. Also tried calling LG warranty, but they do not know of my IMEI either. I got this phone from Swappa, so I left wondering where did the original owner of this phone got it from. He claimed that he got it as a present...

out of curiosity, have you ever tried to flash custom recovery through the bootloader ? If you can, you might also wanna try to make a EFS backup, wipe all partition, then flash custom rom or near-stock rom like this one, just for the sake of testing.

I wanted to flash custom recovery but was unable to do so, because device is still OEM locked. And I am unable to unlock it, because I did not do the confirmation in the Developer Options before device started to bootloop. Is there a way to flash custom recovery without this step in Developer Options?

For now, no way that I can think of. You could try to oem unlock it until it work, just cross your finger I guess?

I have some progress here. Since I was able to sideload various OTA images, I started doing that one by one and seeing if some of them would not bootloop. And after flashing 7.0.0 (NRD91N) from here (https://developers.google.com/android/ota) phone booted successfully and now is working. Will report if I get any problems.

Stuck on team win recovery project please help

I have no idea how to root or anything like that, I bought this oneplus 3 and had a update a week later.. so when I did the software update it took me into teamwin recovery mode and now I don't know how to get back into my phone please help....

Did you buy the phone second hand or did you try to flash TWRP yourself? It shouldn't have TWRP installed by default.
Regardless, you can use TWRP to flash the latest update.
Given that you have TWRP, I'm assuming that you have an unlocked bootloader. Did you notice a warning pop up everytime you reboot your phone before? It should say something along the lines of "your device has been unlocked and can't be trusted". If not, you'll have to unlock it (it wipes your phone in the process).
If the bootloader is unlocked, you can simply download and flash the latest zip for OOS 4.0.3 in TWRP. This will update you phone and replace TWRP with the stock recovery (so you don't run into this problem again in the future when installing an OTA). If you don't intend to modify your phone in any way, then this is all you need to do, your phone should be functional.
There are plenty of threads with detailed guides on how to do all of this.

I'm also stuck on TWRP after stupidly downloading the latest OTA and I don't know what to do!
Phone won't boot normal, just goes off.
Situation:
- Bootloader, Fastboot and TWRP wil load.
- Device seen by windows
- Zip install in TWRP gets stuck at 'patching zip unconditiontally'
- Another zip flashes, but gets stuck at the end, no reboot option (manually but that's not the way)
Can someone please point me in the right direction? I don't care if I lose data, just want my phone back!

Saying i'm a dipsh-t I know, I know, I will do better in the future, for now, help a brother out please

Simple, check the OnePlus D/L sites for this one http://oxygenos.oneplus.net.s3.amazonaws.com/recovery_op3.img and flash it by TWRP or fastboot to RECOVERY. Boot once with the official Recovery and all ist fine again.

This is issue of using a faulty twrp so for that when ur phone us booting up go to fastboot and flash twrp 3.0.4-1 and everything will work

Similar Problem here:
just wanted to flash latest OOS 4.0.3, so I flashed back stock recovery with flashify and rebooted into recovery mode to flash the already downloaded OOS 4.0.3. zip. That's when it began to go poop! After rebooting it just went dark with no Chance to power it on again! No dice with power button, Volume up/down + power button, nothing! Not even the LED's are blinking when plugged in. So this one seems to be basically dead!
I got it once booting again after randomly pushing the buttons (after x minutes!?), but everytime I reboot the phone it just shuts off without beeing able to power it on again. At the Moment it's dead!
Any ideas what might happened? If I get it on again, should I immediately reset it to factory Settings?
I am kinda lost here! Any help/ideas would be much appreciated!

Flashify? Never used it and never trusted apps which flash stuff on a running system. Use fastboot and reflash the recovery partition. Link to recovery is in my former post.
fastboot flash recovery PATHTOIMGFILE

Thank you for your advice! Still a lot to learn! Got it up again, will try as you suggested!

It appeared that my stock recovery file was corrupted , but all is fine again! Thank you very much!

I may have been the person you traded with to get the OnePlus 3, but I took the phone back and after 5 hours I got it up and running.
The phone would boot to TWRP, but even after wiping the entire system and dragging a ROM zip to the internal storage, reinstalling did nothing. It just kept booting back to recovery.
The solution entailed the following.
Download stock recovery IMG. Flashed through TWRP. Rebooted recovery and now was back to stock recovery.
Download the official OxygenOS ROM zip from the OnePlus website and changed the name to update.zip
Next I downloaded Android studio for access to ADB. I had never used ADB before, but I knew this was needed to push a file to the phone.
Needless to say, ADB kept freezing my computer when I would type in the commands to side load.
I deleted Android studio and installed a minimal ADB/Fastboot I found online. I opened my command prompt, typed the command for sideloading, and immediately got my installation starting. It took about 10 minutes to fully install. When it was finished, I rebooted and had a fully functioning OnePlus 3

Phone Potentially Bricked Please Help

So I've had a read through other threads on different sites and youtube videos etc.
Basically I was trying to root my phone using magisk following the video where TK roots a oneplus 5, but was switching out the software for the oneplus 3 version of twrp.
All was going well, connected phone to pc, unlocked it, copied the files across, flashed and installed twrp then when it rebooted after installing twrp it came up with an error saying that "dm-verirty" is not started in enforcing mode, and the phone wouldn't boot past that.
I relocked the OEM, as I couldn't get it to recovery mode (stock) so tried that and now I can get it into recovery mode.
It will happily go into fastboot mode, have tried reflashing stock recovery and trying to update the os via adb.
Have been looking at the Mega Unbrick Guide - but can't get my phone to show up on my pc to even begin there.
Would appreciate any and all help, plus tips for what to do after I get it back to stock as I'm still keen to root my phone but don't want to screw it up again and have to go through all of this again.

The Mega Unbrick guide is your best hope. Did you install all the drivers on your PC? Specially the Qualcomm ones? Also, make sure to press the volume up button like it says in the instructions for 40 seconds. Otherwise it doesn't show up. If all fails, try using a different PC.

Help, might have killed my device

Not 100% sure of best place to post this, but I'm getting desperate now...
I'm pretty worried I've killed my device. After following the guide on how to root with Magisk, my phone is stuck on the white "loading" screen with a G logo. I've since tried to restart, but I can either go into fastboot mode or get the white screen when attempting to boot into android.
Tried to flash the latest factory image to fix it, but that couldn't get that to work. Now the phone isn't showing up on adb devices either. panicking a little bit here.
Does anyone know what to do?

ADB won't work unless the phone is booted into Android or in stock recovery for a sideload.
Does your computer recognize the device when you are in Fastboot mode and type "fastboot devices"? Try flashing the factory image again but make sure you have the most up to date platform tools from Google. Old versions are a common cause of issues.
Did you flash TWRP recovery or just boot to it to root? If you still have stock recovery you can try a factory reset from there but any modified images you installed might be the issue.

like Fury said, your platform tools need to be updated, same thing happened to me.

What didn't work when you flashed the factory image? Do you have the latest sdk tools version of fastboot and adb?

Thanks so much, this is where I was going wrong. Have gone into recovery and rescued it.
Tried the process again to get Magisk working, but ended up the same although this time the white screen only went on for a while before I got an error saying my data was corrupted. Tbh, after all the stress I'm just going to give up on this and live with the phone in stock. All my drivers and adb were installed and setup today, so everything is up to date.
edit...
Not out of the woods yet. After restarting the phone and going through the setup, it's not detecting the SIM card or any wifi networks. I've installed the OTA and wiped data once more after having this problem, still not resolved.

It sounds like you are trying to install Magisk v17.1 like I tried. If so you need to use v17.3 beta. If you follow this thread you should be fine. It even tells you what to do for your original problem, just takes some reading and patience.

I tried it with both 17.1 and 17.3, so not sure what the issue is. Seem to have finally booted up properly with wifi and signal working, so hopefully it's all good now. Gonna give up on rooting.

you may want to try to totally uninstalling Magisk frist with the official latest Magisk uninstaller and reboot and then do a complete factory reset. this has helped me in the past.
my new pixel 3XL will be the first Android phone that I owned that will not be rooted.
