REPAIR HTC U11 - CORRUPT - RELOCKED - S_ON

______________________________________________

I run a phone repair shop,

Customer brought a HTC U11 in to repair,

was soft bricked with an attempted custom rom installation then relocked the bootloader without flashing a working OS to it,

The os version was there but when the device booted a message appeared the device is corrupt cannot be trusted and will not boot,

this tutorial is how I managed to revive the dead device please read below.

Device specs on this model were :

______________________________________________

Fastboot oem readmid

2PZC10000

Fastboot oem readcid

htc_039

______________________________________________

hTc download mode

***relocked***

***production***

htc_ocnuhl PVT S-ON

LK-1.0.0.0000

Radio-8998-002772TOV-1712061121

OpenDSP-V11.6.00347.CB8998_0711

OS-2.33.710.9

Dec 8 2017,21:29:54 (1002308)

_____________________________________________

Bootloader displayed killswitch enabled please disable,

Killswitch/frp

Killswitch/oem unlock

Killswitch/bootloader

when trying to unlock with provided original unlock_code.bin that was provided with the phone & returns not allowed on production build in bootloader, could not flash any stock recoveries or TWRP back to the device, also couldn't receive the unlock code

_____________________________________________

I used tried the following programs to flash :

•htc_fastboot.exe

•minimal adb and fastboot 1.7msi

•power shell on windows 8.1

•minimal adb & fastboot

•fastboot binaries from htc_dev.com

couldn't get anything to flash to the customers phone with any of these so dont bother.

NOTE

I downloaded the OTA's & firmware from the google spreadsheet it had no file for the 2.33.710.9 section there the page it went to was 404 so I just downloaded all of the files with the same CID htc_039 in this case, so just download all relevant files with your matching CID main version shouldn't be an issue as it wasnt for me.

REPAIRING THE HTC U11

NOTE

☆Links are at the bottom of tutorial☆

#1 Go through the files in spreadsheet then download all with the same CID as you have even though the main versions might be different,

#2 try to flash them all with normal fastboot to see what is a signed or close to signed zip and what isnt, (you will know by the RUU errors you face anything but RUU security fail zip from USB command or RUU main version fail ) means it probably won't work but try anyway,

NOTE

I narrowed it down to a few but the one that did end up working was main version 1.11.710.5, but this main Verision was 2.33.710.9 ??? Dont ask me how it worked twice as it needed to be flushed first time it said but it did,

#4 Now the only flash tool that works for downloading to the device in RUU mode is the HTC 10 batch tool.

#5 Place the .zip into the "com" folder which is located where ever the batch tool is installed, in my case was C://Android/com

#6 Open the batch tool with administrator privledges,

select option 3 to open fastboot terminal with the purple screen

NOTE

when entered location of the terminal should be "example" C://android/com on the screen this is where you placed your RUU.zip file.

#7 boot U11 to download mode, with device off hold,

•Power

•Volume down

NOTE

plug the device into the computer & make sure drivers are installed properly and working.

#8 Type into the terminal "fastboot oem rebootRUU",

phone will reboot to RUU mode.

#9 type into terminal "fastboot flash zip <file_name.zip>

NOTE

do not add " " or < > into the command syntax simply drag and drop the file if you do not wish to type the entire filename out.

it flashed all 28 zips twice in my case as it needed to be flushed the first time, these same files would not work on any other fastboot terminal I would only ever receive RUU error zip from USB command or RUU error main version fail,

so there you go this helped me and now I hope it can help you all out with your broken U11 fix please enjoy and if this tutorial has helped you please dont forget to hit the thanks button :)
