ASUS Zenfone 5/6 CN, CUCC, TW to WW

fastbone · Oct 14, 2014

After many many tries i found a way to convert my CUCC edition to WW.

This way should work for any Edition.

1.) Install ADB & USB Drivers
2.) Download recovery image (version should be smaller or equal to desired rom)
3.) Boot to fastboot mode (Power + Vol Up)
4.1) flash fastboot.img from original desired rom zip (fastboot flash fastboot fastboot.img)
4.2) flash recovery image (fastboot flash recovery xyz.img)
5.) reboot to fastboot again
6.) launch recovery from fastboot
7.) upload firmware (adb sideload xyz.zip)
8.) wipe cache
9.) reboot

Your phone should now have the desired ROM & SKU (even future OTA updates should work)

Fot me it worked, the only thing I can think of that I made additionally was to flash ww fastboot image from desired ww original zip.

so all you did was flash the img file ,
then you flash the newest WW rom

meaning if my phone is cucc i can just straightaway flash WW newst rom?

thankyou

Yes i flashed fastboot.img with adb fastboot flash fastboot fastboot.img (from original WW Zip)

than i flashed original WW zip via sideload.

from android mode you can simply boot to fastboot by issuing following command: "adb reboot fastboot"
or to recovery: "adb reboot recovery"

and it should not matter which version you convert to which version as long as you choose the right fastboot and recovery image (the edition you want to have as a result)

doesn't work with CUCC firmware

I tried this method. My fimware is ASUS_T00G_CUCC_user_1.17.40.17_20140812_9510.
At step adb sideoad : Error : "E:signature verification failed. Installation aborted. Can't open /tap/update-script.log. E:Cannot load volume /sisc!"
I used these : 1.17.40.16_ww_recovery.img and UL_ASUS_T00G_WW_1_18_40_11.zip.

Any idea please ?

have you unlocked your bootloader via official ASUS unlock tool?

thank you for your post.
i have manage to update from cucc to ww
your procedure is definitely correct.
on your 4.1 procedure is got mistaken command
4.1) flash fastboot.img from original desired rom zip (adb fastboot flash fastboot fastboot.img)'
when you want to flash it. please do (fastboot flash fastboot fastboot.img)
for some newbie they dint know that by typing adb fastboot wont be able to flash
and they would thought they have flashed it since there is alot of words coming out from the cmd. but its just adb information.
after this point.
do exactly like above.
you will manage to get it done correctly like i am.
just write it for hope to help newbie on flashing.

no ... you need to choose the target region (eg. CUCC->WW choose WW)
