hi gomazia and everybody,

in the last two days I did several test with some users, trying even to assit them via remote connection.

the conclusion is that the U10 phone has definitely a locked bootloader, which is not immediately evident if tested via fastboot,

in fact if you do this command on fastboot rescue mode you get:

(fastboot oem get-bootinfo) you get: <bootloader> unlocked

but the bootloader is locked in the end....

.

infact if you do:

fastboot flash boot boot.img you get:

"FAILED <remote: Security deny - Err:0x2017>"

and on screen of phone "Security deny - Err:0x2017"

MTK DROID TOOL is suppose to flash the CWM or the boot but

not correctly being the bootloader locked

and in the end the boot/recovery are

compromised and you start having bootloop.....

we also removed the immutable.list file, and the result is the same....

it's a mess at the moment, the users having this situation are frustrated <and I can understand you guys, there is not really an easy going solution at the moment and I striongly suggest

TO NOT FLASH ANYTHING VIA MTK DROID TOOL

, even the patched boot and recovery I posted trying to help some users having already the bootloop and not flashed, but just mtk droid tool is creating the mess...

what I can post here is the original B112 firmware from huawei

try to copy the Dload folder in your external SDCARD and from upgrade apk on your mobile chose upgrade locally and try to flash it back ...

the phone should be put in stock recovery and I hope can flash back this rom and at least get your phone back without bootloop.....but again it's a guess I don't know / im not sure the process will go through....

if process fails, you have basically an error message , nothing should happen in the phone......as normally when an offical firmware ( with offical apk ) fails to be uploaded it's not flashing anything and you only get an error.....

inside this B112 official rom there is the famous VERLIST file which is "cheking" your running ROM and allows the stock recovery to flash the rom....here what it's written in the VERLIST....

The only way is to unlock the bootloader via fastboot......problem is to get the unlock code, not possible to apply for unlockcode in the official huawei site being this phone not recognized.....

I will continue study , but I don't have the phone on hands for testing so it's also difficult for me without the phone.....
