Just use option "Unlock bootloader only"
If you want TWRP, go to this link
Download T00F-recoverytwrp-3.0.M2-0.img and TWRP-3.0-M-5.0-20160725-T00F.zip

- Flash the IMG file via FASTBOOT
- And if you want to have the latest version of TWRP, copy the ZIP file to your device. flash it via the TWRP (the one you've just flashed via fastboot)
Why to choose the long procedure? This is the "one click tool" which will do this things together.
You can use "unlock bootloader + install twrp" option for directly flashing the latest twrp-3.0.M5-0 version after unlocking bootloader. The tool will do this job perfectly.
I have tested this tool before and after publishing publicly. And There is no error in this tool. Everything works just fine. People should follow the steps properly.

When I clicked on recovery, the screen got off at that time, then pressing just power button, got me into recovery... This happens every time...but np... I am able to get into recovery...
Sometimes automatic restart doesn't happens. You must restart it manually if automatically restart is not happening.

Houston I Have a Problem!



Thats the only msg that shows now.

I still access the traditional menus with the Vol UP + Power Button command.
But no matter which option I choose, this image always appears. :confused:

Turn off the phone. And wait for sometime. Then again press the vol up + power button and then enter into bootloader. From there go to recovery. That time Don't plug your phone to charger or PC.
If still nothing helps you out then do all the steps again.

This tool is awesome now im getting freezes twice a day only
This tool is just for unlocking bootloader and installing TWRP only. There is a chance for getting screen freeze issue after unlocking bootloader. Screen freeze occurs due to many reason so I can't help you with that. Some users are getting screen freeze issue and some are not after unlocking bootloader.
But thank god, there is solution for these freezes. Just visit this thread https://forum.xda-developers.com/zenfone-5/general/share-discussion-users-problems-unlock-t3629739
And follow the instructions to fix the freeze issue.

Hello juyel92, Ive got a Asus TX201LA (same as TX201LAF). Its a tablet with very similar specs to the zenphone. Its so similar that the temp recovery method works that is used on the zenphone, see: http://www.transformerforums.com/forum/android-trio/47528-cwm-asus-trio-tx201la.html. What I am wondering is if the TX201LA tablet could be bootloader unlocked using your method? I know its a big risk and since support is dead on my device I'm out of luck, and I just want get it to android 5 if possible.

Do you think if I try this will the temp recovery method above allow me to get back if it fails? I'd love hear what you think about trying this. The specs of the TX201LA are here: https://www.phonearena.com/reviews/Asus-Transformer-Book-Trio-Review_id3562

I'm not concerned with altering the dock half as its easily upgradable. Its the tablet that is Dead and no support, just looking for ways to update that. THX

Shell script for linux users

Hello, I just got a 'new' Asus T00J variant and now I'm doing all of that setup from scratch.

I downloaded your zip and noticed that it's only for Windows® users since it has only bat files to do the work.
From your batch, I've made a shell script for linuxers.

Feel free to use/modifty it.

Hello there! My Zenfone5 T00J didn't show any sign of screen freezing... but the camera stoped working, then after several tries i could'nt make it work again.... so i just gave up and did the following:

-Wiped everything using TWRP
-Then proceeded to Re-lock the bootloader using the same toolkit
-Flashed back the fastboot, boot and the recovery.img (in this order) that i got from the Stock Rom on Asus website
-and finally i sucefully flashed the Rom via ADB Sideload

After all this, my camera still isn't working... So, did i just lost that function? and could anyone explain to me How the camera isn't working after i undoing all the changes?

Thx in adv! I hope someone can help me with this ):

EDIT: So.... I dit remember something as i installed Root on my stock T00J again.

3 Yeas ago when i first Rooted my Android, i used this method: https://forum.xda-developers.com/zenfone-5/general/root-asus-zenfone-5-kitkat-4-4-2-100-t2947092

And it DO unlock your Bootloader and then after doing it's stuff, it proceed to Re-lock it... So seeing that it didn't inutilize my Camera before, maybe it's because i didn't boot up the system while having the Bootloader unlcoked.

Could be the reason or maybe it was just luck... dunno ):
