- tried to unlock bootloader by using one of the utilities on this forum - failed and device was stuck in bootlop but could enter droidboot and recovery , was detectable as moorfield on the pc
- tried to flash the official rom image using asus flash utility and now stuck in bootloop but can't enter droidboot at all , my pc does not discover the phone anymore either

if you are not able to go to recovery of fastboot mode. following is the only way to get out of it. read carefully. do as suggested. go to other point after completing one properly. do not use asus flash tool after you enter fastboot mode. use commands to flash raw firmware. see section flash firmware without AFT. OFC after you get fastboot mode back.

Asus Zenfone 2 Bricked , Please somebody help

Hi all members,
I dont know anything much about develpoment, I have ZE551ML 32gb version. I rooted my phone and it was working fine until i installed layers manager from playstore and applied new layers and instantly after restarting the phone was struck on bootloop .. So after searching a bit i managed to open the phone in fastboot mode .
after then i did a factory reset and restarted the phone but the problem of bootloop was still there .. so after searching more i decided to install a custom rom, for that i first used adb tools to flash a twrp recovery in fastboot mode and when i try to enter in recovery mode the phone restarts and enters the fastboot screen itself not on recovery screen. So for me there is not way to enter in recovery mode . So someone please help me and repair my phone i will be very grateful.
Yea you can only install layers for roms that support them. stock doesn't support it. is your bootloader unlocked? if not first do then that try flashing a recovery again.

Firstly , what have you done ? - to get in this position ? there are many threads on here to unbrick devices , reading is best especially if you know what you did to get in the state you are
Me too had a same problem. u would have tried to flash with wrong file. flash with correct firmware it will 100% ok
I had the same problem but this thread sorted it for me:

My Canvas A1 isn't fixed by SP flash tool and is now bricked by format+ download mode

Hi everyone,
My canvas a1 (aq4501) was on September security patch (6.0.1) [unrooted but bootloader unlocked], but suddenly some Google Play services stopped working. So I switched off the phone but the problem was not fixed. Ultimately, I tried to clear cache & the wipe partition but it continuously showed up with the error ''failed to mount the recovery image". Now on opening the phone, it was stuck in a bootloop.
So, I tried to flash stock lollipop 5.1 rom by sp flash tool (5.152400- latest version) [I've earlier done this before as my rom got corrupted earlier] by download only mode but even after successfully flashing (ok done appeared), the phone's rom was not overwrited and it was still hanging on 6.0.1(MOB31E). So this time I tried to flash marshmallow 6.0 rom but again the problem remain unchanged (device was still at 6.0.1- MOB31E in recovery mode even if the flash was successful as shown up by SP flash tool).
So now I tried format+download only mode, again the flash was successful but this time not even the OEM logo (micromax logo) appeared and neither did the recovery mode. That means that my device got bricked. So I found this thread of http://forum.xda-developers.com/canvas-a1/help/micromax-android-one-bricked-unable-to-t2999760. and found that by firmware upgrade mode, we can get our phone back. But as shown in one of the comments of that thread, they got an error "failed to get pmt info", I got the same error too. So, I am helpless as I can't do anything. I've not tried stock KitKat rom yet and also ensure you that all my drivers are correct as SP flash tool is working flawlessly on my pc.
Please help me to fix this problem..........Is there any way to fix it using android one toolkit?????

Are you able to be in the download mode for some time? Try to use DLM backup using lglaf to backup all your partitions.

I would find the stock firmware that you where on and try to flash lgup or flash tool and start again you will lose data but device will be working. And remember to always backup before hand.
First of all thanks a lot as your method perfectly worked , i just have another question out of curiosity if you don't mind , altough LGUP did work of course , i recently noticed that if you don't already have the Google account already registered on the device , and precisely on Lollipop and above , there's absolutely no way you would boot up your phone , i wonder if there's a way to bypass that Google Verification thing !
and just for reference , LG UP doesn't entirely flash the device , it just .... , you know , like just replacing the old firmware without deleting the data , LG FLASH TOOL 2014 doesn't work either , it doesn't even start the flashing process regardless of the firmware , so it's not an option .

pls help me with bootloader loop

i am using lenova vibe k5 the is turning on but it keep stuck in boot-loader page but we can access to the recovery mode and i fallowed the steps by flashing the rom from levovo smart asist by still the same issues i am facing pls help me to fix this issues
i have not installed twrp in my phone and i have tried installing the twrp by pressing the volume + and - and connected to pc for entering the download mode but the pc did not detected the device and i also have installed the usb drivers...
pls suggest me a way to get my recovered
Hey Bharath1705,
Have you tried fatory resetting? Or maybe reinstalling the stock rom? Usually reinstalling stock rom fixes bootloader because it reinstalls it. To install twrp you don't need download mode (also called EDL Mode, used mainly for unbricking the device when bootloader does not work), only fastboot. Follow the installation steps from here: https://twrp.me/lenovo/lenovoA6020.html to install TWRP. I advise to not use Download Mode, it is almost never required to install anything on the phone
