flash marshmallow twrp recovery

then copy B571 twrp back in TWRP>Backups

boot into twrp

Restore B571 Backup,

[Ascend Mate 7 General] Curtz1209:
Hey Guys,

Thanks so much for the quick response Mutahharbashir:).

Starting at C900B560 I tried to use the following method to get the B571 update as using the UPDATE.app kept failing at 5%

Unfortunately this didn't work for me. I followed every step and everything went well without error right up to the reboot.

When I said reboot TWRP asked to install Root. I clicked Don't Install. The device then powered off and rebooted.

It showed the first Huawei, Powered by Android screen and then the boot hung. It then rebooted into recovery.

I tried to wipe and restore a few more times with no luck. I even tried to flash SuperSU 2.64 Pro and still it would only boot directly into recovery.

Eventually I managed to fix it using the following procedure:

I am not sure why Mutahharbashir's method did not work for me.

1) Wipe all mentioned partitions using TWRP

2) Restore B571 TWRP backup

3) Do not Install root

4) Reboot into Fastboot

5) Flash Stock Marshmellow recovery

6) Allow phone to try to boot normally (At this point it didn't boot but decided to do a device reset)

7) Powered on phone and was greeted to a working

Build Number MT7-C900B571

Hope this helps if anyone else gets stuck ;)

Just use the OTA zip if you have a fresh install without root

Es ist oft frustrierend, wenn man alle Antworten weiß, aber niemand kümmert sich darum die Fragen zu stellen :|
[Ascend Mate 7 General] mutahharbashir:
Good to know that you fixed it,

For some devices users face this issue, but for me it worked anyway.
[Ascend Mate 7 General] nozeback:
does anyone know how to rollback from b560???, after i installed it on my mt7-tl10, neither wifi nor fingerprint scanner work, so i'm hoping to find a way to rollback or if anyone has a working twrp backup of lollipop b326, it would be awesome

i installed b560 from the twrp that was posted 2 days ago on the begining of this thread
[Ascend Mate 7 General] stanlawren:
Most people had issues with fingerprint and WiFi after restoring B560 backups.

First off all do a dalvik wipe in TWRP

If it doesn't work restore your original stock recovery and do a factory reset.

B560 is great and working fine. It's the best ROM out there (I stand to be corrected) but if you must downgrade, just flash the B500 rollback package

Es ist oft frustrierend, wenn man alle Antworten weiß, aber niemand kümmert sich darum die Fragen zu stellen :|
[Ascend Mate 7 General] nozeback:
well... i messed up and didn't perform a backup, so there is that, noob mistake i know, and i tried to force update the rollback and it stayed at 5% for something like 20 minutes or so, but thank you anyway

cheers

p.s.: i just installed the backup c185b560 and noticed bluetooth doesn't work either but everything else is better
[Ascend Mate 7 General] stanlawren:
Stop installing backups if you don't know how to go about it properly. Flash the original recovery via fastboot and then install the full ROM normally by putting it in the dload folder and using the service menu

Es ist oft frustrierend, wenn man alle Antworten weiß, aber niemand kümmert sich darum die Fragen zu stellen :|
[Ascend Mate 7 General] nozeback:
in the end,from that last backup that i installed and using the service menu, i managed to get the rollback to work again, and then it's standard rollback stuff

[Ascend Mate 7 General] ogre del:
Just use an app like app extractor. It will back up the app and u can save it.

Flash 2.8.7.0 and format cust partition and then flash cust backup and system only.

[Ascend Mate 7 General] Blue.Ember:
As usual: The absuolte way to rollback from B571 to B331 (EU only)

simple way and simple steps but first (you need to be rooted)

1- Make sure that you have the official recovery flashed.

2- Download this file put it on you exSD and extract it .

https://mega.nz/#!D1AyzALa!t7ZXKAuGwLkNYINWKZNZ47xx9xaMRxkLEUFW5PKC_CA

3- By any root file manager copy the oeminfo to this extension

/dev/block/platform/by-num/hi_mci0/ ------------ and agree on replace

4- Copy the custom.bin file to /data ---------- and agree on replace

5- Make a restart.

6- Flash the rollback by putting it inside dload on internal sd and flash it using buttons method and it will success then check the build number if it B500 keep going :cool:

7- Flash the LP rom any version you want by putting it inside dload on internal sd and flash it using buttons method.

TADAAAAAA you're on LP again.

Hi guys,

I have red all post from last 50 pages...but still I am not sure what version of MM to install since I am not sure what is relation between country and CUSTC.

My phone is MT7-TL10 (gold), vendor hw, country: meafnaf

Originally bought in Dubai, but I am living in SE Europe (Serbia).

I can not remember what was original KK, I think B123. For sure I don't know what was CUSTC number.

Transition was:

B123 - > B128 (OTA update), or telephone came with B128 directly

B128 -> C900B313 (manual update, Incremental OTA)

C900B313 -> C900B331 (manual update, Hungary, Channel-Others, Full firmware image)

So currently I am on C900B331 and country meafnaf. What version should I install to come to B560 or B571? Please tell me full version, together with CUSTC number.

For what region is CUSTC 900, if CUSTC 185 is for middle-east?

Is my current ROM OK, since country is meafnaf, but ROM is for Hungary, Europe?

[Ascend Mate 7 General] chudy_85:
info for all

when you want dowgrade to b331/b522/b560 from b571 do it this

1. Firts you must change oeminfo and custom.bin

2. If you have twrp you must flash stock recovery but here we have failed because bootloader its locked ( on screen in fastboot you have unlocked ).

3. Unlock bootloader again using your code but if you dont have use honor tune to read code.

4. Now you can flash stock recovery

5. Now download B500 downgrade pack and copy dload to your internal memory

6. Power off and use 3 bottom to flash downgrade pack

7. Now copy B522 to your internal card and flash that same as point 6

8. Phone reboot and now its optimalization .
[Ascend Mate 7 General] mutahharbashir:
You should install middle eastern version.

You should go for B560 middle east.

it is ok when you follow steps on guide chucky...i made i will help you in private if you Accept Skorpi...
[Ascend Mate 7 General] Dz08:
Thank you.

I am still confused with CUSTC numbers since I red that there is also C900B560...meaning that C900 is not only for LP, but it is related to region.

Also, I have few more questions.

In order to help other rookies as I am, I am writing my discoveries and things that bothers me.

If I am wrong, please correct me, since I think this is crucial for all ordinary users of Mate 7 who want just to upgrade their phones.

If you have time, please answer to those questions.

I am listing CUSTC number (region where telephone is originally sold) found so far:

C10 - Russia

C185 - MiddleEast

C432 - Europe

C636 - AsiaPacific

C900 - ???

C145 - ???

and country info:

eu - Europe

meafnaf - MiddleEast&Africa

spcseas - Malaysia

cn - China

by - Belarus

So, country info and CUST number should be paired. Since CUSTC nuber is part of ROM version (or it should be) this means that ROM and country should be paired.

- for country eu, correct version should be C432B560

- for country meafnaf, correct version should be C185B514 or C185B560 OTA

Circumstantially, if you change country info, you can change CUSTC (ROM).

What confuses me is that my country info and ROM are not paired (country: meafnaf, C900, ROM for Hungary, Europe) but the phone is working very well.

Can someone explain me how?

If I am using phone in region different from country info (like me), does this matters?

What is the difference between different ROM for different regions? (I noticed that in my initial ROM version I had Wakti application, after flashing to C900 I have Play store)

Since I have unpaired country and ROM now, can you tell me what should be correct transition:

C900B331 -> C185B514 -> rollback C900B500 -> C185B560

or

C900B331 -> C185B511 -> rollback B326 -> C185B560 OTA for B326

or

since I am from Europe and I am using telephone in Europe, to change country to eu and update C900B331 -> C432B560

or something else?
[Ascend Mate 7 General] chudy_85:
For you if you have meafnaf you should flash b326 or b329 rom and then flash my b514 and update to b560 if you do it correct your firmware be c185b560. For me flash b326 then update ota to b560

Send from ? . If I help you buy me ?
[Ascend Mate 7 General] Dz08:
