(As usual the risk is on your responsibility)

New edit

Working now on MT7-L09

Thx to pasquyx and Shadow_recruit for testing it on MT7-L09


you should have root on the device

Files you may need:

1- Roll back file (this is the trick)- BOTH MODEL

DRIVE
LINK

UPLOADED
LINK

MEGA
LINK

2- rom B326 for middle east
(MT7-TL10)

LINK

(MT7-L09)

LINK

3- oeminfo file for China (don't worry it will not change the iemi numbers)

LINK

3- FX FILE EXPLORER

https://play.google.com/store/apps/details?id=nextapp.fx

4- FX ROOT ADD

https://play.google.com/store/apps/details?id=nextapp.fx.rr

5- Build.prop file if you device model showing Jazz
(MT7-TL10)

https://mega.nz/#!20QXmKrZ!HYhN_7u0sBc445C_6r6D4ug2HuqdCgM_721ANosUa9g

(MT7-L09) *NEED TO TEST FROM ANY ONE TO CONFIRM IF IT WORKING

https://mega.nz/#!XhxR2BpD!O6xkfX8MR55imidxwNlH9p3r2ugLOYwnM-dheTOQT38

-extract the file what you donloaded for oeminfo on ext sdcard

-open fx file explorer and grant it from SU, go to system root and make sure you mount read-write

-copy oeminfo from the extsdcard to /dev/block/platform/hi_mci0/by name and agree for overwrite, after that select the file and choose security and mark for all "read-write-exec"

-copy custom.bin for extsd to /data then choose security and mark for all "read-write-exec"

-check the country info now by *#*#2846579## if it cn, so you are on the right way

-now make a restart but first you should be on official recovery, if you are not turn off the phone open it again on bootloader and flash the official recovery ten restart

-after restart it should make "optimizing"

-after it finish take the roll back and put it in dload on the extsd

-make a local update ( if you don't have it go to dial and type *#*#2846579#*#* and choose 4)

after you make a local update the roll back should complete 100% because this file is the only roll back that compitable with B511
I promise you it will success with 100%

then put lollipop rom 326 on dload and make local update
and again I promise you it will success with 100%

-if the device didn't open after 10 mins, flash all files for the 326 by fastboot
Boot
Cache
Recovery
Cust
System
Userdata

-now you have a 326 rom but chines version.

-make root again and replace oeminfo and custom.bin for middle east version here then make a restart

final step is to make a reset from settings

Files here only for TL10

[stepi1]

Yes, i noticed it. Just downloaded all needed files for L09, i will try later and see what happens.

 

[stepi1]

Tried on l09 but it fails in transition package. downloaded all the files from huawei finnish site. Well, i think i just wait for the complete marshmallow image.
there is something with whatsapp notification, because i don't allways get new message notifications and also usb-debug and hisuite dont work. when i enable usb-debug and connect cable, it won't rise flag about permmisions and computer keeps saying that device is unathorized.

Hi everyone,

this is the absolute way to roll back from Marshmallow B511 to any previous version whatever it's a lollipop or kitkat.......

(As usual the risk is on your responsibility)

*******This Method is tested only on MT7-TL10 (Please don't try the files on this thread on different model number ********

Files you may need:

1- Roll back from lollipop to Kitkat (this is the trick)

DRIVE
LINK

UPLOADED
LINK

MEGA
LINK

2- for me i tired with kitkat rom B119 sp03

LINK

3- extract all file from B119 Sp03 and be ready to flash all of them via (fastboot)
(so may unlock your bootloader and you should have all files for adb and fastboot)
*recovery
*boot
*cache
*cust
*system
*userdata
it's an easy way, no need to change the location or make any special things \\\\\

download the rollback file which I mentioned before, put it on dload on the extSdcard, and make a local update ( if local update not showing for you try a search for HwOUC.zip and flash it with Twrp recovery)

after you make a local update the roll back should complete 100% because this file is the only roll back that compitable with B511

then put what you want kitkat or lollipop rom ( for me I tried with B119sp03 kitakt and it's fail on 40%)

now enter the bootloader mode and flash all img's for the rom which you tried to flash

after finishing it opne on a stock android, so no issue try a factory reset and everything will be normal after that

Edit (important): to prevent the fail on 5% you should check the location on your device by this code
*#*#2846579#*#*
It should be hw/meafnaf (middle east version)

If it showing "file is not found" try to make a reset from settings>>backup/restore

This is important edit due to the update of B511 is for middle east.....

Software install failed after Local Update!

 

[Blue.Ember]

Software install failed after Local Update!

It's worked for me anyway, I try again maybe there's a problem with the file, wait for the update.

This is stock recovery for mt7-l09 to back from twrp to stock recovery of b326 5.1.1 in order to install MM.
You can flash stock recovery in fast boot mod if you rooted your device or installed twrp previously:

You should go into bootloader mode and open the command window from the folder that contain the stock recovery by pressing Sift from keyboard and right bottom in the mouse and choose open command window here, then type the following

fastboot flash recovery xxx.img

Replace "xxx" with the name of the img

If it showing okay then failed
Try to unlock the bootloader again by typing

fastboot oem unlock 0000000000

Replace 00000 with your unlock code
Then try to flash again
