We say possible because even though it works for the user who posted it, it might not work for everyone or every variant for Zenfone 5. Adding to the problem we cannot check it because none of our 3 Zenfone 5s with our team members face the screen freeze on bootloader unlock.
Since we found this method out in the wild we wanted to share it with all our Zenfone 5 fans so that those who face this frustrating issue can try it out for themselves and see if it works for them.
Disclaimer : This method is not tested by us and while it will not damage your device it might lead to loss of data or need a complete re-flash of your device ROM. It is safe to backup all data before proceeding. This method also requires root and thus voids your warranty. If you loose access to bootloader you have to approach a service center.
Okay so now that you are sure of the risks lets go ahead and check if we can solve this screen freeze once and for all.
These are the steps highlighted by the user from XDA :
1. Boot to TWRP and install the X AnwarMov Kernel
2. Boot to bootloader.
3. Flash dnx from ZenfoneIndia2X-4X-Kernel-V8__2_21_40_30WW.zip
4. flash if.bin from the X AnwarMov (you will need to extract the zip file)
5. Reboot to system, use the phone, open some apps, perform some operations
6. Reboot from 5-6 times.
Commands to flash dnx and if.bin files :
dnx : fastboot flash dnx <filename>.bin
if : fastboot flash ifwi <filename>.bin
That should pretty much solve the freeze issue as claimed. Please don’t forget to share your results with us in the comments below and we will as always keep looking into this matter until some permanent solution is obtained.
