Hi everyone,

Roll Back from 513 to 331 all credit for [MENTION=4190256]chudy_85[/MENTION] check the link here

http://xdaforums.com/showpost.php?p=65371195&postcount=207

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)

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

LINK

final step is to make a reset from settings

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:

[Ascend Mate 7 General] Blue.Ember:
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
[Ascend Mate 7 General] silentflight711:

[Ascend Mate 7 General] Blue.Ember:
You have 2 options:

1- Downgrade from LP to KitKat so you can able to flash any lollipop update you want.

[Ascend Mate 7 General] Blue.Ember:
Marshmallow update take some time to start, let him keep it for 15 mins it will start after that
[Ascend Mate 7 General] Blue.Ember:

[Ascend Mate 7 General] zia1288:
He did it last night and it is still restarting. And yes he installed Update.app

Was he supposed to install update.zip? If yes then how to do it via adb now?
[Ascend Mate 7 General] chudy_85:
ok i write how i back to b331 eu.

I use this guide from this topic but i dont change oem to africa. I stay on china and when i flash b326 i flash twrp and restore my backup b331 and do it wipe advance wipe data, cache, dalvick cache and i lost china oem. I restore china oem when my phone boot.

Now i back to stock reovery and flash this update.app ---> https://mega.nz/#!lwBiSQCS!M00gzlYs7T3dbUtLswfNs3Jv2KNs2-hyGMz4NzHuEzI and when i see 95% my fone go to wipe data and cache. When its boot i check my oem and i have eu. Now i flash b331 from this link ---> https://mega.nz/#!lxAiAJba!mjmSnr5mtWZqeKpkYPXjnWO4AALBY196kwYlda4eg90 and my phone have stock b331 with eu

when i try flash stock b331 when i change manual hw china on eu i have fail but now when i use update.app i don't have no bootloop and working b331

Some time i have locked bootlooder i dont no why but on my screen i have unlocked. We must unlock again

Great effort from your side [MENTION=4190256]chudy_85[/MENTION], if you agree I will update the post to add a link for your method
[Ascend Mate 7 General] lovelygaaz:
It is recommended to install via local update.he must power off the phone and when it is restarting , hit volume down several times while releasing the power key...the phone will boot up....otherwise, he must unlock bootloader and install twrp then restore the related marshmallow twrp firmware backup. Or install the recovery.img

Boot.img or cust.img and system.img of mm via adb commands...
[Ascend Mate 7 General] chudy_85:
yes you can added but remamber i change b513 to b511 and then do it my step. Bootloader its locked when we change oem. Its locked all the time and we must unlock

---------- Post added at 01:17 PM ---------- Previous post was at 01:05 PM ----------

I don't test back from b513 using update.app what i added brcause i take to long to back with my method. If any one try test you can but remember you can fail and do it backup , unroot change recovery to stock and try.
[Ascend Mate 7 General] lovelygaaz:
If you fail to install stock recovery, you should flash stock kernel then install stock recovery then install rollback package

How can I change JAZZ to correct model noMT7-L09. on unrooted, locked bootloader?

Sent from my JAZZ
[Ascend Mate 7 General] Blue.Ember:
Put all files on ext sdcard

Roll back file

326 rom

And middle East files

Boot into recovery

Press on mount button

Mark on system

Go back and press on advanced button, then choose file manager

Go to system folder and search for build.prop file and press on it then delete it

Go to the same file you copied on your extsd press on it and choose chmod 755 then swipe , then press on it again and choose copy then go to /system folder then choose select on the right down corner, when the copy completed go back to the system folder again and choose the same file "build.prop" then select chmod 755. After this you finished the first file, remainig files you should copy it as same.

After you finish copying all files reboot the device from reboot button then reboot system, keep it restarting for 2 mins (maybe it will start or not), then boot into recovery again take the roll back file which should be in a folder lonely rename the folder to dload and open it, hit select on the right down corner and choose copy to /emmc then go back to the same folder again on extsd and rename it again with different name than dload

Make a reboot from reboot button but choose bootloader(if it didn't enter to bootloader enter to it manually)

Flash the official recovery for the same rom you were on it by this command

fastboot flash recovery 11.recovery.img

Make sure it will give you 2 Okay,

If it failed unlock the bootloader then try again

fastboot oem unlock 0000000000

Replace Zeros with your unlock bootloader number

Then try to flash the recovery again,

Now type fastboot reboot to make a restart but before that be ready to press on vol+ vol- when it restart directly

It will boot into upgrade mode and it should reach 100%

If it completed flash the twrp recovery again, and copy the 326 rom to the extsd with the same way for the roll back file

The flash the official recovery again and reboot into upgrade mode by vol+ vol-, if it reach 100% keep the phone loading for 20 mins at least.
[Ascend Mate 7 General] Blue.Ember:
Before changing files make sure that you uninstalled superSU and you deleted the su folder, and important thing every time when you make a reboot it will ask you to install SU please don't swipe and choose "do not install" button.

Download the build.prop for your model from the first post and replace it from /system, you should have root to make that.

Would there be any problem to update official mm in future if I keep it as it is? (JAZZ-b513)

Sent from my JAZZ
[Ascend Mate 7 General] CloudCompute:
After trying various roms KK, LP and MM(B511 and B513) on my MT7-L09 Middle East version, I have finally decided to stay on B511. It's stable, has good battery backup and RAM management and has an option to change DPI from default 480 to either 440 or 400. I like 400. This one feature alone is enough for me not wanting to go back to LP.

This would be my recommendation for a bug free B511.

Option 1. if you have a unmodified phone, (stock rom KK or LP, locked bootloader, stock recovery, unrooted) then use local update to get to B526 first and then to B511. You can do this without loosing any data. Stock rom for B326 and updater for B511 can be downloaded from the following thread.

http://xdaforums.com/mate-7/general/huawei-mt7-l09-l10-stock-firmware-ota-t3275784

Do a factory reset after you get to B511 and you should be good to go.

Option 2. If you have already tampered with the phone, then you can use TWRP recovery tool to restore your phone to B511 using the TWRP backup file from the below thread.

http://xdaforums.com/mate-7/general/request-mt7-l09-b511-android-t3305883

Prerequisites are unlocked bootloader and TWRP recovery for MM. Once you have restored from the TWRP backup, do not do a factory reset. Just wipe the Cache and Dalvik Cache, and boot up normally without adding your google account. Go into the app setting and wipe data for all applications one by one. Now add your Google account, and you should be good to go. You'll loose Huawei Swype keypad and the option to hide navigation keys if you do a factory reset.

All credits go to the folks that have uploaded the ROMs in the threads I have referenced.
