Best method to unlock zenfone 5 bootloader without any freeze/random reboot!

I'm using RR 5.6.9 by @tank0412 for last one week.

So far I didn't face any freezing or random reboot issues. What I did is as below:

1. Flash/downgrade to UL-ASUS_T00F-WW-2.21.40.30-user firmware.
If you know how to flash stock firmware then skip step 2-13 and just do it.
2. TURN OFF the device. Press and hold Volume Up+Power to enter to fastboot/droidboot. When the ASUS logo shows up, release the power button and keep on pressed the Volume UP button. This will take you to droidboot/fastboot mode.
3. Check whether your PC detects the fastboot...

Code:

---

fastboot devices

---

if not, go to device manager and install the fastboot driver(by online). if fails, install from the PC by selecting the android device from the list.
4. Download this image UL-ASUS_T00F-WW-2.21.40.30-user.zip: http://ift.tt/1r1eMYy
If you have different SKU, you need to find the right firmware(version-2.21.40.30) here: http://ift.tt/1qyyOdt
5. Extract fastboot.img, boot.img, recovery.img from the zip file and copy to ADB folder to flash. Copy UL-ASUS_T00F-WW-2.21.40.30-user.zip to ADB folder as well.
6. Run the below commands:

Code:

---

fastboot flash fastboot fastboot.img
fastboot reboot-bootloader

---

wait for reboot.....

Code:

---

fastboot flash boot boot.img
fastboot flash recovery recovery.img

---

7. Then go to recovery by selecting from the menu, you will an android logo with "!" sign. Press power+vol down+vol up sequentially and simultaneously, don't release any of the buttons. You should be in recovery mode.
8. In the recovery, select wipe data/factory reset
9. Select wipe cache partition
10. Select apply update over adb sideload
11. Now check whether your PC detects the ADB over USB. if not, go to your PC's device manager and install the ADB driver online. if fails, install from the PC by selecting the android device from the list.
12. After successful detection, run below command

Code:

---

adb sideload UL-ASUS_T00F-WW-2.21.40.30-user.zip

---

13. Download this official tool for Unlock Bootloader: http://ift.tt/1r1eCAm
14. Extract the downloaded file and copy the .apk file into you SDcard. Install that .apk(if it says untrusted app, then go to settings>security>enable Unknown sources).
15. Run the installed app and press unlock. wait and let it reboot. After this, your Asus splash screen will become white & bright.
16. Now do a clean flash for any custom rom.

You guys can try it. :highfive:
