Reports that this MAY WORK for some phones only = IT works for mine but as always @ own risk< i would say its quicker and safer than the hack method

Attached File  U8815 rom downgrade upgrade.zip   997bytes   2421 downloads

put this on external sdcard (just the dload folder+ contents) not the zip extract it 1st

hold volume down +up and power on

wait a few seconds till finished

then remove from sdcard and replace with ANY official HUAWEI update.app (rom version) again dload folder method


note ......

this is a copy of u8815 middle package original is 777K

mine is 997K as i used no compression when i zipped it back up



now have the tool NOT working for me

All i get is a pink bar that gets to 70% then fone reboots

IS THIS what others get when they say failed?

before it said unpacking fimware > pink bar > installing firmware> green tick OK

so it seems I have recreated the problem


If you get a failure the only option is to use the hack method not the huawei tool http://www.modaco.co...on-bypass-hack/

after using the hack method I was successful in using the above U8815 rom downgrade upgrade method

Is this the one from the B927 thread? If so then it fails to help in some cases - mine fails to update using this.

what about the bootloader thing?

is Bootloader still locked at ICS...so if you install ICS and then want to go back you'll still have to root it via that UnlockBootloader.exe?

The progressbar jumps immediately to about 2/3 and stays there until i pull the battery.

Install of B927 doesnt work on my phone too. Im on B926.

That is the same as I get. This method is certainly not a fix for all.

If you are on B296 you can update to B297 via fastboot, that is how I have done it to see if it works. I'll upload the extracted files later if anyone is interested.

Yep that's what I got when I used the middle update.app. It showed just the pink bar with out any notifications. After I downgraded using risky IMEI=0 method I then just installed the 927 update.app and it worked perfect.

Also if you check the log in dload folder on your phone it says failed.

I've just used this method to downgrade from B927 to B888.

Worked fine for me.
