[IMPORTANT HELP] Zenfone 2 stuck in bootloop, no way to resolve it.

Hi guys,
Yesterday I rooted my phone with one click root (method 3 of this thread http://forum.xda-developers.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596) and everything worked fine. Also instelled Xposed (from the same thread). The thread says I can install OTA without un-rooting, so there was an system update and I installed it. Now I'm stuck in bootloop. I can't go in recovery, when I try is like I normally turn on the phone. I don't see any android robot or error message, it seems like it turns on normally. So I can't install stock firmware. Tried to unlock bootloader, so I have to open adb, but if the phone is turned off, it don't detect it, and If it is on(but in bootloop) I've to authorizate it from the phone, but in bootloop it is impossible. Tried to install custom recovery, but Un-Tethered Recovery needs unlocked bootloader, and installing Tethered Recovery gives me the same problem: if is turned off it don't detect it, if is turned on, it needs authorization. I've installed adb (of course), asus drivers from here (https://software.intel.com/en-us/an...ion-instructions-for-intel-android-usb-driver) and manually from here (https://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices). I've tried to do all this stuff from Windows 10 (64 bit) and form WIndows 7 (32 bit).
Hope you guys can help me, I really don't know what to do, I just want my Zenfone 2 551(Z00AD) back :crying::crying:
Thanks.

After you get into bootloader you can flash the .63 Rom you'll find the prerooted roms by shakalaka in the thread for changing CN to WW here in this forum

Hey guys, just received my phone today and I cannot get pass through this erro msg...
Tried pretty much everything and still getting the msg, already wiped the system, tried the recovery mode, nothing works... problem is, I cant access the celphone memory since its internal :\ is my phone dead?

What error message? Did you unlock the bootloader? Are you rooted and do you have custom recovery? Need to know how you got to where you are now, step by step.

I rooted my devide and then I tried instal the slim via TEMPORARY CWM which I think was my mistake all the way...
After I installed the slim rom the device gave me the option to restart which I accept and from that point I got the error msg with the android laying down and the "Erro!" msg...
Cannot get pass from that point, tried everything and I'm start to geting worried.... I cannot even access the sd card from another device since there is no sd card :|
sorry about my bad english...
Edit: I managed to enter in the recovery mode, already tried the wipe data/factory reset and wipe cache partition and nothing seem to work... still receiving the erro msg... I'm out of option man, I'm kinda new to this root/rom stuff and I think I got screwed in my first attempt :\
Edit 2: there is a ADB option, apply update from ADB, is there anything I can do with this option? I already dowloaded I stock version from the android...

You have 2 options, 1. Sideload from stock recovery the full zip of stock Rom or 2. flash via bootloader, w/adb sideload make sure you are on (adb 1.0.32) or it won't flash, if you choose bootloader option refer to the flash WW from CN tutorial located here in xda or search in chinaphonearena for shakalaka tutorial

And for future reference until you have unlocked bootloader you cannot flash any custom rom

Recovery mode never shows up even after it's selected and restarts

I was attempting to install a custom rom and now I can't even get into recovery mode. The option comes up after entering the bootloader but then it just reboots to the bootloader screen. If I pick normal boot it does the exact same thing. Any help much appreciated.

Can you flash from the bootloader? First thing to try is clear cache, be patient it's a slow process, if that works then flash a pre-rooted rom, you can find the in the thread to flash ww from cn. That should get you running again

I can't get to the standard recovery to clear the cache or to flash a prerooted rom. It seems I can talk to the device with my pc using fastboot but not adb. I did clear the cache by running the command "astboot format cache" but it didn't seem to help.
Thanks

did you run the offical Bootloader Unlock from asus? if so u will need to wait for a fix.

no I have not run that. I think I need to reflash the original img files using fastboot does that sound right?

The reason I had you run clear cache was to make sure fastball commands works, you need to flash new rom from fastboot, look at the thread to flash WW from Cn it will give everyone you precise instructions and d/l locations for the images to flash and fastboot commands I would post the link but can't copy it from this app, sorry, but the thread is titled flashing from CN to WW

Is my phone bricked? Please help.

Okay, so I'm another person who OTA updated their rooted Zenfone 2.
ADB won't detect the phone. I've tried different ADB installations on three different computers. I've tried updated the drivers and everything. I've tried different USB cables.
My phone unfortunately has the stock Android recovery utility. There doesn't seem to be an option to install a rom from SD.
I've accepted that the phone is bricked. But I thought I would make one last effort on here before I go and buy another phone. Is there anything else I can do?
Any help would be appreciated!
Thanks

Note 7 stuck in bootloop and loads into bootloader

Hi Guys,
I have a Note 7(Australia-Vodafone) it is stuck in bootloop and loads onto bootloader. I tried to flash the Vodafone, Australia firmware through odin and also tried to use the smartswitch to help me get my phone back to life, but no success. Please help me.
It was never rooted or for that matter, the USB Debugging was also turned off
In the bootloader I get the following error,
dm-verity verification failed..
Need to check DRK first.
TIA
