[Device Reviews and Information] ZSan1:
What I tried out. G750-U10 ( Europe ) stock 4.2.2 - B116

1. RootGenius - get root ( bootloader not unlocked ) but SU running.

2. MTK Tool: get root access as described above made full backup, backed up IMEI ( see above post too ).

Using ROM linked from [MENTION=2786922]pavel22[/MENTION] - I succesfull flashed the secro-reworked succesfully. Phone boot normally.

I rebooted the phone in recovery: fastboot flash ... recovery - access denied ( bootloader locked ) !

deleted immuntable.list ( no change ) bootloader locked.

How to delete easilly.

a. Install Total commander ( I just like it )

b. Go to /System select properties set ( 777 ) R/W .. all good

c. Go to immuntable file > Properties set rights ( 666 ) ger R/W but not execute as will fail to set

d. have a copy to SD card ( neve know ) . Rename the file to immuntable.old

e. Delete file

Others posted in the forum other method' s...

Using SP-Tool - I tried to flash various recovery files - no success. I also added the checksum.INI setting it to 0 for a signed file. None of them signed...

[IsEnableChecksum]

CHECKSUM_SWITCH=0 ( originally way 1 )

[CheckSum]

PRELOADER=0x0000ea06

..........

Does anyone has a working signed CWM or TPRW ?

Not needed anymore as I managed to flash a recovery but... See RUN 2 below

3. Try to use Magic TPRW : Stable version 2.8.1.0 ( see post above for link ) waiting for download http://xdaforums.com/showthread.php?t=2798257

Staus: Failed, during update you can see on screen the adb commands. Also I had messageboxes saying but boot is locked. I will upload the log file as maybe contains some usefull information.

log from device, I also attached the blocks from MTK : https://drive.google.com/folderview?id=0B0q4ALMExF6ZN3ptRzIwNDl2Rk0&usp=sharing

Maybe someone could use it as contains all the data from build.prop

4. If step 3 ( or 2 in case I can have a signed recovery ) then flash the SupeSU using TPRW or CWM - I should be rooted right ?

For the record ROM's for U10: ROM's: huaweidevices.ru Be aware this site uses EXE to download the ROM, will put garbage on your PC and contains malware.

RUN 2 - Checking another possibility

As wrote in this post ( above ): #2291 based on what I found here on forum the Greek version fo ROM should have unlocked bootloader and kernel.

What I did using that ROM - I do not have the immuntable-list file as I delted it long time ago

a. flash reworked -secro

b. Flash boot.img and Uboot

c. flashed custom recovery TPRW using magic TPRW - success but during the process message... your boot.img is locked.

Result: Most probably the TPRw is there but since kernel is locked I have bootloops again. No stress fastboot continue works..

Final result: the Greek version posted by [MENTION=2786922]pavel22[/MENTION] has locked boot.img - so .....

I downloaded a China-T00 ROM that supposedly has unlocked boot. Guess what. SPTool failed as the IMG files are not signed...

Does anyone has unlocked kernel for 4.2.2, signed one of course as otherwise SPTool will fail. As mentioned the one posted by [MENTION=2786922]pavel22[/MENTION] is locked.

[MENTION=5520996]ahmednasser37[/MENTION] - did you succeed ?

Thanks
