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.

Hello all, I have searched for more than a couple hours and just seem to be getting nowhere. Here's the deal: I have an HTC One M8 with TWRP, root, an unlocked bootloader and S-ON. I want to install Lollipop, but can't take the OTA.
I know a little bit about what I'm doing, I tried to flash a rooted stock ROM but it didn't take. I wiped all directories but the internal storage. Also wiped the Dalvik, `but I could not get the update to take. I tried a few other things but out of fear of bricking my phone I wasn't very adventurous. I flashed the backup I made beforehand and it worked fine.
I think I have the wrong file...? Could my S-ON be the problem?
Sprint HTC One M8 (HK edition)
Android: v4.4.4
Sense: v6.0
Kernel: 3.4.0
Baseband: v1.08.20.0916
Build:3.31.654.2
All I want to do is flash lollipop. Will I have to lock the bootloader and go back to stock recovery to do it? Can I use adb sideload to install it via adb?
Thank you for your time.

I'm pretty sure my phone is toast.
PLEASE HELP, it worked just fine before I took your advice...
I relocked the bootloader and verified it multiple times before doing this. I made sure everything was exactly the way it was explained in the instructions, all files were correct.
I put the phone into fastboot, which I verified with adb.
I ran the Sprint_HTC_One_M8_HK_4.20.654.10_RUU .exe file and followed the instructions.
Both the program and pphone are currently frozen. They have been this way for almost 2 hours now.
The phone is stuck at the black HTC splash screen and the installer says
Updating...(0/7)... #(<--- these dots are still in motion like its installing)
Updating the ROM image on your Android phone...
[color=redPlease do not remove the USB connection from the Android phone or launch any programs during the update process.[/red]
Remember, this operation will take about 10 minutes.

Ok, the phone is not recognized by adb but is still recognized by fastboot, can I reboot it into TWRP by using
Code:
fastboot reboot recovery
then just flash the backup I made before all this crap started?
*EDIT* RESOLVED
Never mind, I resolved it myself. I just typed
Code:
fastboot reboot
and hit enter. It booted right up.

I looked through it and all user made folders are gone, but all user downloaded apps are still there. I also noticed that superSU root access was off, but the 'apply on boot' option was turned on, could this be what crashed the updater?
Hello everyone, need a little help if possible .
The say curiosity killed the cat, well… it killed my phone. To be more precise I wanted to know if my 550ml (with unlocked bootloader and running cm12.1) could run a 551ml firmware so… I did install thru TWRP the superzen firmware and after that the screen turned black. Can’t see anything . Not even in fastbootmode, no logo, no nothing. If I turn it on and plug it to the pc it shows, I see the internal memory and the sdcard. It’s gotta be from the different resolution that 550 and 551 have but how do I change it since I can’t see anything?
I did a userdata reset thru fastboot, wiped cache , reinstalled stock recovery ,boot recovery, tried to install stock firmware, still no change. I even managed to enter stock recovery and did an adb sideload of the latest firmware from the asus site.
As for now the phone boots, the capacitive buttons respond, the led indicates that it charges, the pc sees it but no matter what I do the screen remains black. Most likely I’m on the setup wizard but like I said I don’t see anything.
So… What can I do now? To the Asus service with it or …?
I'm not much of a forum user so go easy on me. Thank you.
Not sure if it's going to make a difference but here is an idea, try sideloading a cm recovery and flash a cm rom and see what it does...

Unfortunately it does not work, when i try to sideload a rom with twrp it gives this: error closed. Probably because usb debugging is not enabled... and in cwm different error: Device unauthorized...
Are you sure bootloader is unlocked?
It has to be unlocked cause i can flash permanent TWRP and when I enter TWRP recovery i can touch the buttons, even tried to do a restore in the dark... But nothing... Still the black screen persists... Thank you anyways.
PS: Well it looks like I've managed to resolve my problem. Thanx to user helroz i have found in his google drive a Raw firmware and I was able to flash it via fastboot with Asus Flash tool and now the phone booted, no more black screen for me. Lesson learned.
The backstory: I have no experience with rooting and or flashing custom ROMs. Prior to today my ze551ml was completely stock, running on the official android M update. I had a need to do a factory reset, but the phone would simply reboot. I assumed this was a problem with the update so I download and attempted to install the downgrade to l. Naturally it crashed mid downgrade and I thought it to be bricked. So, I started Googling and realized I was able to get into fastboot mode, but not recovery. Following a guide I located I attempted to flash the preroot ROM located at the link below:
http://forum.xda-developers.com/zenfone2/development/rom-pre-root-img-t3079590
Well, it appeared to have worked, but now the phone refused to boot at all after being turned off. So, more Googling and I proceeded to follow the full unbricking guide below:
http://forum.xda-developers.com/zenfone2/help/thead-bricked-phone-updating-to-mm-tips-t3452785
Partway through step 1.3 the phone restarted itself and booted right up into Android L! Success I thought to myself, but it was not to be. I proceeded to download the FOTA L update and it downloaded fine, but when I clicked to install it simply rebooted the phone. Tried a couple of other times with the same result. I realized that Supersu was installed so I did the full unroot assuming that was the problem, but to no avail. It appears that the updates can't install because the phone is incapable of entering fastboot or recover mode. Anytime I attempt to enter fastboot via hard key or through adb the phone hangs on the ASUS logo. Adb detects the phone when it's connected via USB, but of course fastboot can't because I can't get it into fastboot mode at all.
Any tips on how to get fastboot operational again so I can start applying updates again? Every guide I've located has started with "boot into fastboot/recovery" which simply isn't an option. Any help is appreciated.
Edit: Well, I think I've reached the end of the internet trying to google for a solution. The phone works, but it looks like it's stuck on build 2.13.40.13 until the end of its life. If anybody has any ideas I'm still hoping for a solution, but I can't find anything describing how to restore fastboot if the OS is intact.

Thanks for the response. I've tried this a dozen times, but unfortunately (this is going to sound weird) since it's not completely bricked it is only detected as Moorefield for a few seconds when started. This allows the xfstk tool to detect it and begin the download, but not long enough to complete the process so it times out. The only development access I have to the phone now is via adb, but since I don't have root I'm very limited in what I can do via command line. Since I can't access fastboot I can't achieve root. It's just a comedy of errors now.

The problem is that it's only recognized as Moorefield for a few seconds which isn't enough time for xFSTK to complete the install. Do you know of a way to force the device to stay connected as Moorefield?

Plug the phone to the PC, be sure the phone is completely off and then hold power + vol- for a few seconds. You must see the "Moorefield" driver permanent in the device manager.
Btw... I got the same problem (four lines, not bootloader, not OS; xFSTK FW+OS failed) and I'm stuck in this step :/

I've tried this many times, but it only shows Moorefield for a few seconds. I'm assuming this is because it has a fully operational OS so it doesn't stay in the generic USB device mode.
EDIT: I misread your original post. Holding power and volume DOWN does keep connect it in Moorefield. Thanks so much for that. The problem now is that once xFSTK gets to downloading the OS it reboots the phone which takes it out of USB mode and disconnects the tool. I'm still stuck where I was before, but that's a little progress. Any other thoughts?
New update. I'm able to get to the point of loading the OS from xFSTK by skipping the FW part, however it continuously fails. My assumption is because it can't overwrite the existing OS. Any other ideas?

Kidnova, reading this post I could fixed my problem. The "issue" was in the xFSTK where you put the flag (0x800000807). A guy on the threat said to put "0x80000807" instead of "0x800000807" (note that there is "0" from difference).
"those who are not able to keep device connected. take care of few steps
1. in xFSTK option menu change the flag override value to 0x80000807 not 0x800000807 ( don't forget to click gp value over ride)
2. while connecting to xFSTK attach usb to computer. hold power button for 20 seconds to make sure it power downs completely. then hold the power button down and click power button. wait till device vibrate or computer makes detection sound. leave power button but keep holding the volume button for few seconds"

Hi, got the same issues, I've read many posts. Tried all of the million options. What was your final way of doing it, do you remember?
So after 2 hours of searching, trying and failing, I just decided to post here and see what help I can get.
Situation is exactly like the title. Had Lineage 14.1 installed, and decided to update the phone. Rebooted the phone and went to TWRP recovery. For whatever reason, I decided to reboot the phone, which ended up in it coming back to TWRP. This repeated until I got the stock recovery, which put me into bootloader instead. Bootloader is now locked, I can no longer get into recovery, and I'm stuck in bootloader for as long as this continues.
So far I have tried:
--------BEFORE TWRP RECOVERY FAILURE AND BOOTLOADER LOCK---------
Factory Resetting
Formatted and flashed ROM
A couple of ADB commands
--------AFTER TWRP RECOVERY FAILURE AND BOOTLOADER LOCK---------
Replaced recovery image file with stock
Idiotically replaced bootloader image file with stock (Locked, can tell since Android N is no longer bugging me with preboot notification which was present before when bootloader was unlocked)
Idiotically replaced the system image file with stock
A slew of fastboot commands (You can comment and I can see if I have attempted them)
Attempted to continue the fastboot process
Attempted to use an automatic rootkit. Did not like my device, so it did nothing at all.
Manually unplugging the battery
Haven't tried:
Placing rom in sd card, like I've seen people say elsewhere. (No SD card available)
Anything else you tell me that I haven't done
I'm not really interested in keeping any files that I've had before, if that is not already made clear.
Anyone that can help me, I really want this to end. :crying: :crying:

Hey! Need a little help. I updated to Android 11 Beta 2. Now my phone is stuck on a boot loop. A li'l different though, phone boots up normally and stays on the lockscreen and alive. Can receive calls. But once I unlock with the pattern it shows ' Phone is starting' works for a good 2 seconds and then ends up on infinite bootloop until I Power down. How do I access my files on PC ? If I can get just few files out of it then maybe I can perform a factory reset . Please HELP!

some older app is causing the loop you mayneed to factory reset through recovery or flash factory images to ur devices ,( please backup your all data and i will advice you to remove the screen lock if possible as it may cause issues after flashing older or newer images

Facing the same trouble, did it help?
Hi, I finally managed to solve this!! Was able to get the phone working with data intact.
So I got exactly the same problem yesterday and was looking around for a solution when I bumped on this thread, the solution suggested to use Android Flash Tool can work only if the bootloader is already unlocked, USB debugging is on and you edit the flash.bat file to remove -w from the command line, which would not work in my case since my bootloader is locked and unlocking through ADB would wipe all data
So the only good solution is to do an OTA UPDATE USING ADB SIDELOAD, I just downloaded the OTA file, connected the phone to computer, booted into recovery and used ADB to sideload the OTA and boom, the phone is its pristine self again, with ALL DATA intact
