[Device Reviews and Information] biobio76:
Hi esipoko and all U10 "BRAVE" owner,

for the "brave" who really want to try something untested and new....here is a package and instruction that can potentially help you in doing this,

there is no guarantee is going to work and it's extremely risky....so as said only the brave can try this and be aware this can potentially freek up your phone....I DON'T TAKE ANY RESPONSIBILITY FOR ANY BRIK OF YOUR PHONE, just to be extremetly clear, you do this at your own risk

https://mega.co.nz/#!tggFSJJa!I4pe4KCBNj81Zu57k-vYC8h_09Yyxl1oqOu0qrqp9Ig

instruction and explainatio:

1) download this hope_package.zip and extrac of your computer

2) inside you will find:

- dload_packageflash folder: reneme this folder as simply "dload"

AND COPY IT INTO THE ROOT OF YOUR EXTERNAL SD CARD

- ORIGINAL_B610_delapp : this has been taken from official B610 firmware and it's basically the B610 system/delapp folder with

official apks inside

- ORIGINAL_B610_build.prop : this is the original B610 build.prop who is into the B610 firmware at following rooting:

system/build.prop

3)

explainatio:

the U10 firmware has basically the

bootloader blocked

and a

particular stock recovery installed

, who is nearly impossible to replace with the common ways ( with MTK droid tool or SP FLASH TOOL...both fail )

the package I upload is an OFFICIAL PACKAGE taken from chinese forum and has been created for users that have the B610 firmware installed and that want to upgrade to KITKAT via

local upgrade package installation

....but focusing on what there is inside this dload/UPDATE.APP file:

you can see the packge, once flashed via stock recovery,

it's suppose to install:

-new stock recovery

-new uboot.img

-new PRELOADER ( who is the key of or scope and purcpose )

-there are some other minor files necessary for the flash verification, the main two once are VERLIST and CRC

here is the extraction of this VERLIST:

G750-T00 V100R001CHNC00B642

G750-T00 V100R001CHNC00B641

G750-T00 V100R001CHNC00B640

G750-T00 V100R001CHNC00B608SP06

G750-T00 V100R001CHNC00B608SP06_Debug

G750-T00 V100R001CHNC00B608SP05

G750-T00 V100R001CHNC00B608SP05_Debug

G750-T00 V100R001CHNC00B608SP04

G750-T00 V100R001CHNC00B608SP04_Debug

G750-T00 V100R001CHNC00B608SP03

G750-T00 V100R001CHNC00B608SP03_Debug

G750-T00 V100R001CHNC00B608SP02

G750-T00 V100R001CHNC00B608SP02_Debug

G750-T00 V100R001CHNC00B608SP01

G750-T00 V100R001CHNC00B608SP01_Debug

G750-T00 V100R001CHNC00B610

the flash will happen IF the package found one of the above mentioned firmware installed....so that's why I have taken the main files to be modified from the B610 firmware, becasue is the "older" firmware more "closer" to your U10 firmware

4) what and how to do ( for only THE BRAVE )

PS: forgot to tell you that first thing you must do is REMOVE the immutable list file.....

into the immutable list file there is a list of thing that can't be romeved if you don't take out this immutable list file:

/system/bin

/system/build.prop

/system/etc

/system/fonts

/system/framework

/system/lib

/system/usr

/system/vendor

/system/xbin

/system/app/HwLauncher6.apk

/system/app/HwLauncher6.odex

/system/app/SettingsProvider.apk

/system/app/SettingsProvider.odex

as you can see build.prop is in the list...so first thing is to remove the immutable list file as described in my post #152

( http://xdaforums.com/showpost.php?p=51331587&postcount=152 )

THEN

ORIGINAL_B610_delapp:

the contenent of this folder MUST be put into your actual stock firmware into this rooting/folder:

root_of_your_phone_ /system/delapp/ "copy here" and with rootexplorer MODIFY PERMISSION AS RW-R-R

IMPORTANT:

if the delapp folder is not there

YOU MUST ADD THE COMPLETE FOLDER

.....accordingly to the U10 firmware you are running can be you have already this system/delapp so in this case just ADD THE MISSING APKS in my package , if completly missing create this delapp and put the apks inside...then change permission to apks and to folder delapp accordingly

IMPORTANT

rename the ORIGINAL_B610_build.prop into buil.prop and ( after have done a backup of your build.prop - example rename your build.prop into buil.prop.bak ) replace it and with rootexplorer MODIFY PERMISSION AS RW-R-R

***: NEW ADDITION THINGS TO SAY ON BUILD PROP MODIFICATIONS ***:

please find attached at this post the file build_prop_comparison.zip

inside you will find:

U10-B112 build.prop

U10-B113 build.prop

T00-B610 build.prop

program winmerge.exe

install on your windows computer the program winmerge

THEN, accordingly with your running firmware, use winmerge to make a comparison between the U10 Bxx build.prop you have and the T00-B610 build.prop

you will see they are quite similar.....to try to avoid any brik of your phone, I STRONGLY SUGGEST TO NOT COMPLETLY REPLACE the B610 build.prop with yours...but start "slowly", step by step, to modify your build.prop accordingly to the main information you see in the B610 build.prop

you need basically to replace all you see as :

G750-U10 V100R001C00B113

HuaweiG750-U10 C00B113

C00B113

G750-U10

with B610 corespondent and equivalent informations.....save the changes and

USE THIS NEW BUILD.PROP to replace yours

, changing then the permission ad described = RW-R-R

maybe you can try first to modify only the "

displayed name

"...and see if it's flashing....then add changes step by step and see if flash goes thorugh....there is no a SURE THEORY in doing this...and especially nobody knows exactly what the stock recovery needs to be able to get greenlight for flashing....so try by yourself ( and at your risk :)

just to show you what exactly must be done find here a picture self - explanatory:

STILL IMPORTANT:

thanks to user "princeofabyss" that upload me the backup of the U10-B113 SYSTEM.img, I made a comparisong between this U10 system and the B610 System, and there are several apks in the B610 system that are not included in the U10 system....

I have exctract the missing apks and put in a zip file. I uploaded it for you here:

differences_B610_U10.zip (TOT 65.3 MB )

https://mega.co.nz/#!59JCjAwa!bNRZSh8OWfA9UfqQPS9-ij9z6Tw5SZMGV78tAMrNgoI

to be sure the flash will not fails....you have to exctrac this zip file and copy all apks into your U10 system/app AND CHANGE PERMISSION ON EVERY SINGLE ADDED APK AS RW-R-R

this will prevent a potential failur when CRC will check for mandatory apks to have installed...example you will see some are stupid apk like VMALL.apk, but maybe needed for verifying and check you are allowed to flash...

5) once done the modifications....go to Settings / Updates / System updates / Local update and chosing the local update you can pick you the

dload folder you have previously copied

....

phone will automatically boot into stock recovery and start the flash, and I hope will find this time a B610 build.prop who will provide "false" info to stock recovery and allow the flash....

in the packege the CRC file is also checking what you have into the system/delapp .....that's why I told you to put B610 apks inside your system/delapp ...trying to match this additional check....hope will work....

if this will happen without failure, you will finally flash your installed locked PRELOADER for an unlocked one.....

the phone then will reboot and I'm qquite sure it's no more rebooting correctly, you can have bootloop or blackscreen.....but the most inmportant thing you have changed the bootloader and

now you can finally use SP FLASH TOOL and completely format / flash new firmware on your phone...so then you can simply follow my post #897 ( http://xdaforums.com/showpost.php?p=53968943&postcount=987 )

and flash it preatty new...don't forget to have previously backed up your NVRAM with MTK DROID TOOL and obtained ( the *.bin and the *.rar )

6) if this process will not go through, having changed completely the build.prop... you must replace it with your buil.prop.bak to have your phone U10 back running again, but this can become then very difficult if

your phone is not booting anymore....so here, my friends, can be you definitly say hello to your phone.....as said, only the brave.....

important consideration:

- this try must be done on an UNROOT phone so be sure to have removed the rooting prior to start the local update...

- instead of replacing your WHOLE build.prop with the B610 build.prop you can make another try as suggested by dancrow , means use a

free build prop editor downloadable from play-store ( https://play.google.com/store/apps/details?id=com.jrummy.apps.build.prop.editor )

you can rename with this apk the U10 firmware into T00 firmware(G750-T00 V100R001CHNC00B610) ...even if I don't think will be enough to cheat the stock recovery...but you can try ....

guys, hope this post gave you an idea of what can be done as extremely and dangerous "nice try" .....more then this, at the moment, there is no solution ....your bootloader is blocked so nothing can be replaced if you don't unlocked the bootloader..

cheers
