[Zenfone 2 Laser General] Aquarian:
Finally unbricked my ze550kl

A Disclaimer: You might brick your phone or it might be completely unusable, FOLLOW THESE AT YOUR OWN RISK! Any problems you encounter or global nuclear wars you cause while following these steps are your own responsibility. If something goes wrong (such as a power outage or loose cable) in the middle of the flashing, it will brick your phone. If you don’t know how to deal with such things, take your phone to a proper service centre instead of following this post. I will not be held responsible for any thing going wrong with your phone.[/COLOR]

First i would like to say i m using a ze550kl 2g 16gb rom variant with chipset msm8916. my phone was completely hard bricked with no led indicator no screen display nothing. just that my pc recognised it as qualcomm diag usb 9006. also my phone was not rooted. did everything mentioned in this thread. i m completely new with this no knowledge abt qualcom chipsets.

I followed post no. 83 (thx Satyam mishra) and addy692 but to no avail. i was getting stuck with error fastboot.exe stopped working while flashing raw file using the flashall.aft file. Then i checked post no 83 again and found the raw file was for msm8939 or something. which wasnt my chipset. spend around 14 hrs googling and finally found raw for msm8916 and voila. just had to bring my phone to 9006 by procedure mentioned in post 83 by using minipartion and flashed emmc (.bin) file using emmc raw tool. and my phone rebooted in some lollipop test build. now my imei and serial no. were gone. So i used qsml imei and sn writer ver 1.4 using this guide (http://androroot.com/2017/08/solve-invalid-imei-and-serial-number.html.) I got my imei number fixed but couldnt get my serial number updated. After that i thought of taking a risk and flash flashall.bat file in raw firmware file given by addy692 for ze550kl by double clicking it and my phone started in lollipop build. I updated to latest mm using FOTA. no problems.

I m using Windows 10 64 bit fresh installed. Software installed Qpst, Minimal adb and fastboot 1.4.2, emmc raw tool, mini partition tool, qsml imei and sn writer. Asus usb driver from asus website. qualcomm usb driver. I also ran this command before installing drivers. run “CMD” or “Windows Terminal” as administrator and type:

bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING ON

Restart your PC or Laptops, and you should see a watermark at the bottom right of your desktop.

Just google ([firmware27]ZE550KL_MP_RunChange_0721_Ver136_8916_V001) and u will get a uploaded raw (.bin) file. thx to addy, satyam mishra, and other various bloggers i was able to revive my zen2. Qualcomm is truly unbrickable.

Note that this information took me atleast a week to compile after asus and my local service centre guy said i will have to replace motherboard. so pls reasearch first and understand procedure.

Note. This procedure worked for me and i still have my serial number wrong on my phone which i cant update. so do this at your own risk. I will not be held liable for anything wrong going with your phones. All the best.

P.S.

M stuck with 2g network dont know what to do
