This is not my original work.I am just sharing this GUIDE for easy rooting of L90 with latest updated, those are not supported by towelroot.
I have tested this method myself and it is working perfectly for me, but it is also possible that it might not work for you for some reasons, so don't panic, just post your problem or whatever error you are facing (please attach screenshot if possible). I or other thread members will try to troubleshoot it. After resolving the problem I'll update this post, so that other members do not face such problem again
First of all Install USB Drivers from following link :-
Click here to download L90 USB Drivers
After installing USB Drivers, download Rootl90.zip file attached to this post below and extract it to C Drive of your PC.
On your phone, Goto Settings -> General -> Developer options and enable USB debugging by ticking the check box.
(If you are unable to find Developer options, then go to About phone -> Common -> Software Information and continuously tap on Build amount for 5 to 6 times, it will enable developer options)
Now Connect your phone with PC in LG Software mode, open device manager and confirm ADB Device listed at the top of the list, as an image attached below:-
Now open Rootl90 folder, that you extracted to the C drive in the first step.
In this folder, press and hold shift key on the keyboard, right click on blank place and click on open command window here. The command prompt will start with c:\Rootl90>
Now type following commands one by one in the command window (simply copy, paste and hit enter) :-
adb reboot --bnr_recovery adb push start_restore /temp/start_restore adb push permaroot.bin /temp/start_restore adb reboot
- Command 1
After this phone will reboot into recovery as shown in the image below
Now Proceed to Command 2.
- Command 2
- Command 3
- Command 4
