Follow chudy instructions for me couple posts above yours.
[Ascend Mate 7 General] stanlawren:
Well it seems the only way to install 571 is through a fresh install of B560 anything else and it will probably fail.

C900B560 meafnaf users, try clean install B560 again and then try the B571 OTA. This time it will surely install

Es ist oft frustrierend, wenn man alle Antworten weiß, aber niemand kümmert sich darum die Fragen zu stellen :|
[Ascend Mate 7 General] mutahharbashir:
you mean people with meanf

can simply flash B560? or have to install transition package & then again flash B560 ?
[Ascend Mate 7 General] elmira.ab2llahi:
Thats my question too shouldn't we change the vendor to update b560 ?

Someone told me that I should change the vendor then updat to b560
[Ascend Mate 7 General] chudy_85:
For all.

This its instruction how correct update to b571

If you have others region not eu you must change to eu.

When you do it downgrade to b500 and flash b560 full.

Check your region you must have eu and then go to setting/about phone and check do you have C432B560

If you have you can download update via ota or flash full b571

You must have stock recovery to download and unrooted device without all mods

Remember for now we can't downgrade to b560.
[Ascend Mate 7 General] elmira.ab2llahi:
For me it's c900b500 ,is it because of the vender and country ? (Country is meafnaf)
[Ascend Mate 7 General] stanlawren:
Even if you change vendor to eu you still won't be able to update to B571 unless you fresh install B560

I just was wasting my time in internet as usually and find this polish b331 image

http://consumer.huawei.com/pl/support/downloads/detail/index.htm?id=71663&key4=mt7-l09

Intresting thing is that there are two update apps inside it, one is under dload folder as usually but there is also another one under vendor/hw_eu and that is much much smaller one. also the filepath it self gives a hint about downgradeing from b513 to b331. It also looks that the file has been put up bit of hurry because there is even chinese markings on folder names etc.

date of the file is 4.2.2016

There is also quite a new image from sweden and it's also b331, just downloading it to see if it has same files.

I know that but the question is I'm on mt7-l09c900b500 not c432 and chudy says that I should be on mt7-l09c432b500 to be able to update to b560 and also I have to change the vendor
[Ascend Mate 7 General] chudy_85:
Added MT7-L09C432B571 TWRP Backup. I use Twrp 2.8.7.x for backup
[Ascend Mate 7 General] stanlawren:
If you update from C900B500 you will get C900B560. Then try install B571 immediately after installing the B560. That's what I was talking about. You will probably get C900B571 too.

Edit: if going to B560 from B500 doesn't work, first install B522 and then B560. Also take note that going through B522 will definitely reset your phone so backup stuff you don't want to lose.

Manuals update.

Copy dload to ext SD card and then go to dialer type *#*#2846579#*#* and then push 4 and 1 but you build number must be MT7-L09C432B560. When you have that and you have model number HUAWEI MT7-L09 you can update but remember your Hw must be eu

i managed to recover it by flashing stock recovery> did factory reset > flashed twrp > wiped again >done

i dunno it was problem with B560 or my phone itself

When you do it wipe in twrp 2.8.7.x you lose your Hw vendor.

I rolledback already from 571 to 560, it's a simple way to rollback nut you need to be rooted and bootloader unlocked, the problem is I checked about new full package for 571 and there is no update, but I received the OTA one, so my question is, is there anybody received the full package for 571 on L09!!
[Ascend Mate 7 General] mutahharbashir:
how you rolled back?

through twrp backup ?

It's still failed if you tried to update manually, the problem wasn't from the update file or from you country/vendor info, I have hw/eu and tried many times to update it manually but it keeping fail on 5%, so I tried different way to update it and I succeeded, anybody is here to try before going to sleep????
[Ascend Mate 7 General] Velocesuper:
Hello,

My phone is a MT7-L09, the original ROM is : MT7-L09V100R001C00B121SP03.

I have received this OTA : MT7-L09V100R001C00B130SP03 and after, I make these manual updates (full ROM):

- MT7-L09C900B329

- MT7-L09C900B331

- MT7-L09C432B522

- MT7-L09C432B560

And now, if I use: C432B571 OTA for C432b560 (file: "update.zip" in "dload" on SD), I get this error:

"No upgrade file!"

If I use: C432B571 Full OTA (file: "UPDATE.APP in "dload" on SD) ; I get this error:

"Software install failed!" (at 5%).

Do you have an idea ? Please.

Edit : My Rom is MT7-L09C900B560, sorry ! :o
[Ascend Mate 7 General] Blue.Ember:
Ok... Last edit, this update whatever is full or OTA is not accepting any chance to update it manually, so save your effort and battery, there is one last way I need someone to try it but he should have an unlocked bootloader, I already tried it and succeed but I was already on 571, so I need some one to try it on 560, it's simple just extract update.zip file and put all extracted files inside dload beside the update.zip, so the files will be as pic below, then update with 3 buttons.

NOTE: DO NOT TRY IT IF YOU DON'T KNOW HOW TO RESTORE YOUR PHONE IF IT CAUSE ANY DAMAGE, I'M NOT RESPONSIBLE FOR ANY DAMAGE HAPPENING TO YOUR PHONE....
[Ascend Mate 7 General] mutahharbashir:
Its definitely OTA

Brother please can you confirm if huawei id app is working for you?

I was on Kangvip B561a V2. I first restored back to stock B522 using a nandroid backup. Then I changed my region to eu, downgraded to B331, and then all the way down to kk B145, and then upgraded back to B522. I received an ota for B571, and I used that to upgrade to B571 bypassing B560. All seems well except that now I can't access Huawei id or Huawei cloud any longer. Is anybody else seeing the same issue? Will going back and using the full upgrade package for B571 make any difference?
[Ascend Mate 7 General] Velocesuper:
Sure, is locked by Bouygues Telecom (French provider).

Yes, I use Rollback from TL09, because my phone is a TL09 :D

I've got a good news and a bad news. The good news is that I fixed my Huawei id and Huawei cloud. B571 came with Huawei id, but no Huawei cloud. I uninstalled the app that came with B571 using system app remover(root), then ported Huawei id from my previous rom and installed Huawei cloud using an akp that I downloaded from internet.

Bad news is that my nephew just threw my L09 on the floor and broke the display, :crying::crying::crying:so much for gorilla glass protection. The phone is still alive but using it with broken display seems risky. I'll take a nandroid backup and put the phone away until I get my display replaced.
