Angry [IMP][ZU_GPe][How-To] Restore to original Google Play Edition firmware!

[ intro ]

So I recently got the ZU GPe and have been trying few things... and I messed it up bad so things were not even booting properly

I was trying to get it back to factory settings but couldnt find any direct way and no one XDA had any good info to go by...


finally i was able to get a procedure to restore to original Google Play Edition firmware! so here is a step-by-step procedure (with pictures) to restore your phone to original firmware!



[ requirement ]



[ how-to ]

[ 1 ] Get into Graphical Bootloader

to enter graphical bootloader you can either use the command:
Code:
adb reboot bootloader
OR

power down device connect the USB cable to phone before connecting the other end of cable to PC keep the VOLUME UP button pressed

this will trigger Bootloader mode:





[ 2 ] Get into Stock Recovery

while in the Graphical Bootloader use the VOLUME keys to navigate to "Recovery Mode"



now press the POWER button to select it, device will now "reboot" and trigger stock recovery entry


[ 3 ] Reveal Stock Recovery menu

at first you will see:



to combination to "reveal" the Recovery menu is:

POWER button + VOLUME DOWN (first press POWER button and then TAP the VOLUME DOWN key ONCE)


you will now see this:





[ 4 ] Flashing FULL OTA ZIP

in the recovery menu use VOLUME keys to navigate and select using POWER button
  1. now navigate to "apply update from ADB"

  2. select it!

  3. this will enable "adb sideload" mode in recovery on phone

  4. now on you PC (hope that you have downloaded the FULL OTA and kept it easily accessible) enter the following command to send the FULL OTA ZIP via sideload:
    Code:
    adb sideload PATH-OF-FULL-OTA-ZIP-INCLUDING-ZIP-FILENAME.zip
    e.g.: if u have saved the KOT49H full ota to c:\ then enter:
    Code:
    adb sideload c:\830f5fda644bfc55f82a4e01fb5fadae4b64fad6.update_1278-8069_R3C_KOT49H.S2.2052_Final_signed.zip
  5. this should start the transfer process to phone and flashing will start once file is fully transferred



  6. after flashing is complete I recommend doing a Factory Reset! THIS WILL WIPE THE INTERNAL SDCARD AND ALL DATA WILL BE LOST! select "wipe data/factory reset"

  7. now select "reboot system now" and device will reboot! thats it!


you will now be on original Google Play Edition firmware!



hope this helps!



regards,

Thank you for this. I had gotten to the first picture in step 3 accidentally while trying to guess my way through button combo to unlock bootloader in flashtool. Glad to know there is a way to enter stock recovery if needed. My investment is already paying dividends!

@DooMLoRD I installed Minimal ADB and Fastboot and connected phone and can't figure why it doesn't show up when I type adb devices.

Edit...got it needed to go to device manager and pick drivers.

Would this overwrite the Advanced Stock Kernel with Dual Recovery? I'm looking to get my phone 100% back to stock.

Pretty certain my bootloader remained unlocked after using this process.

About the drivers? They were the ones from flashtool folder but had to reinstall them for adb to work. I assumed they were there from unlocking bootloader and flashing kernel.
