Downgrading from Kangvip, Debranding to AL10l, Updating to Oreo

Hi everyone

I am happy to report that Android Oreo on my Huawei Mate 8 is working perfectly.

All these months I was on L29C432B582 kangvip B595 but I was reluctant to debrand to AL10. That changed after experiencing Android Oreo on my new beautiful Honor Note 10 which I purchased recently. I finally debranded my mate 8 to AL10.

Below are the steps that I followed to downgrade from kangvip B595 on L29C432 , debrand to AL10 & then update to Android Oreo. 3 stages involved

Downgrading

? Rebooted to TWRP

? flashed L29C432B560 stock (dirty flash)

? After flashing stock B560 I have stock recovery

? Then I dload 90mb rollback package which makes the phone ready to downgrade to marshmallow

? Removed the rollback package from dload folder and replaced it with l29c432b192 update.app

? dload again

? now you are in marshmallow

Unlock bootloader, Twrp, Root(required for debranding)

? connect the phone to computer, don't forget to turn on usb debugging & install drivers for mate 8

? On your computer open SRK tools

? unlock bootloader, install twrp for emui 4.0 since I used l29c432b192, then root. You can do so these in SRK tools

Debranding process

(Disclaimer - Debranding is risky process - do not proceed if you are unsure)

? Once you are rooted follow this video by somboon [youtube]JZVsIKtdgV4[/youtube]

I used AL10C00B386

? In that video most important step is that changing oeminfo. In that video he will do a reboot & he will get optimizing system. If you dont get, then don't worry. Just reboot to system check if your country info changed or not by typing *#*#2846579#*#* project menu will open. Go to network information query ? vendor info

If it shows vendor all, country - cn then it's fine if it says it doesn't exist or anything then just flash boot, cust, recovery, system of Al10c00b386 firmware in fast boot, followed by dload of AL10c00b386. Then every thing will be back to normal. Your about page will show correctly with correct build number, model number.

Debranding is done.

Updating AL10 to Oreo

It will then system update to B577 ? B596

Then if you don't get OTA to 8.0.0.829 then use hicare to update. Select country china.

I know it is tedious (3 stages involved) but I have perfectly working Android Oreo on my Huawei mate 8 ???

With Oreo, mate 8 feels like a new ?

Very snappy?

Incredible standby battery optimization?

More options & customization?

Navigation dock?

Bluetooth ?

Display Resolution ? select 'smart'

I love it & totally recommend to those who haven't done it yet. Few screenshots below.

Cheers ?

[Mate 8 General] A.lemane:
Can all this be undone ?
[Mate 8 General] apat26:
Yes. Definitely. Which version you are now and where you want to go?
[Mate 8 General] A.lemane:
Nxt-l29c432b583

I want to go full Oreo but only if it can be undone

Do I have to use the erecovery ?
[Mate 8 General] apat26:
Not necessarily. But coming back to your rom is certainly possible. So go ahead n enjoy Oreo...:)
[Mate 8 General] asgharkhan1:
i haven't tried that but am sure it can be undone by same procedure again

---------- Post added at 01:30 PM ---------- Previous post was at 01:29 PM ----------

is there any way to root oreo?
[Mate 8 General] Leo_83:
Magisk should work
[Mate 8 General] apat26:
Since you will be flashing Chinese ROM only, ready Rooted ROMs are available which you can flash on top of Stock ROM. Links are posted in this thread.

Also, you can ROOT stock with Magisk easily.

Just follow steps on Magisk thread in XDA.
[Mate 8 General] asgharkhan1:
but what about twrp nd how am gna flash magisk?

---------- Post added at 01:40 PM ---------- Previous post was at 01:35 PM ----------

thanks man will try that but is there any twrp for oreo?
[Mate 8 General] apat26:
Twrp is posted here by [MENTION=4537581]hamadazh[/MENTION]. No one has fully tested yet. Basic function works. Don't know about backup n restore.

Although for magisk n root only, you don't need twrp.
[Mate 8 General] Leo_83:
Exactly [emoji4]
[Mate 8 General] asgharkhan1:
so how will i flash magisk without twrp lyk in fastboot nd i have to unlock bootloader?

[Mate 8 General] A.lemane:
So after debranding I can flash stock Chinese rom with costume recovery ?
[Mate 8 General] apat26:
No no dear...system updater will take you to Oreo. 100% official.
[Mate 8 General] ceriqdesign:
Is anyone here have update to B834?more improvement or same like B829?
[Mate 8 General] apat26:
I am on it. Same as B829. I guess only the security patch of August
[Mate 8 General] ceriqdesign:
I see..thanks for the info..are you updating using dload or system update?
[Mate 8 General] apat26:
Both wont work. Huawei has not pushed it yet officially so even FF wont work.

Through Hurupdater or HWOTA method only till it is approved for installation.
[Mate 8 General] A.lemane:
Can u share the link for hwota that u tested

Does anybody have a problem with magisk hide CZ I can't get it to work
[Mate 8 General] ceriqdesign:
Lol..see the first page bro..put the file in hwota folder with update.zip, update_full_public and update_all_hw into SD card..
[Mate 8 General] apat26:
In a couple of new HRT B834 ROMS, they have included face unlock with lift to wake option which is nice. You can unlock with screen off.

Huawei can implement this if they want. First is to have Oreo for ROW. Long wait it is.
[Mate 8 General] Georgian51:
Is this HRT B834 available?
[Mate 8 General] tarekcod:
help

in attempt to update to oreo i accidentally flashed wrong firmware on my L29 now (VIA HWOTA) i am on 8.0.0.046 (OHGE) with OEM lock greyed and booth FRP and bootloader locked.

how can i get the FRP UNLOCK KEY.????????
[Mate 8 General] Georgian51:
fastboot flash oem unlock xxxxxxxxx(bootloader code)
[Mate 8 General] tarekcod:
this code is for bootloader unlock.

there is another key for FRP unlock.

---------- Post added at 09:13 PM ---------- Previous post was at 09:12 PM ----------

i cant unlock the bootloader if FRP is locked.

and oem unlock is greyed.
[Mate 8 General] A.lemane:
Go DC Phoenix
[Mate 8 General] Georgian51:

[Mate 8 General] A.lemane:

DC PHOENIX IS A PAID APPLICATION.

---------- Post added at 10:38 PM ---------- Previous post was at 10:32 PM ----------

is there any tool for dload mode:confused:
[Mate 8 General] apat26:
Just factory reset and you will have that option back again
[Mate 8 General] apat26:
Yes. You can flash it on Chinese B834

Also, a new version is available now. B835 stock on FF

Will post Baidu links in sometime
[Mate 8 General] tarekcod:
i did that several time without success :mad:
[Mate 8 General] Georgian51:
At this time version is the phone? AL, DL, L29 .... Can you get fastboot?
[Mate 8 General] tarekcod:
L29 BUILD: system 8.0.0.046

i can boot normally.

fastboot cammands are working (except oem unlock ).
[Mate 8 General] Georgian51:
if you can install twrp and use this method https://www.google.ro/amp/s/xdaforu...fficial-firmware-recovery-t3769279/page4/amp/

[Mate 8 General] tarekcod:
my bootloader is locked :( i can't flush custom recovery.
[Mate 8 General] Georgian51:
try the dload method https://xdaforums.com/mate-8/general/guide-how-to-downgrade-mate-8-emui-5-to-t3515202
[Mate 8 General] tarekcod:
i didn't found a Rollback Package from EMUI 8 to 7.
[Mate 8 General] Georgian51:
There is no 8, try with 7
[Mate 8 General] tarekcod:
already try it ......... didn't work.:(
[Mate 8 General] Georgian51:
Have you tried erecovery?
[Mate 8 General] tarekcod:
yes ... and every time it failed " getting package info failed" even when i use firmware finder DNS method.
[Mate 8 General] Georgian51:
Try again unlocking the bootloader and then a factory reset. I was also stuck with the unlocked bootloader but it was still blocked. Do not rush to use DC as surely is a solution. Spread the XDA well and there is definitely a solution.
[Mate 8 General] A.lemane:
Tried the dload method ?
[Mate 8 General] tarekcod:
sadly it fail at 5-6%.
[Mate 8 General] A.lemane:
Try both regions
[Mate 8 General] alexito696:
frp unlock: entering the google account at the start of factory values, later you must then delete the google account from settings and make a factory reset from settings

---------- Post added at 10:41 PM ---------- Previous post was at 10:37 PM ----------

for bootloader unlock enables the developer settings by pressing several times on the compilation number (8.0.0 ....) and enables oem unlock in developer settings
[Mate 8 General] tarekcod:
there is no google account on it, the wrong update delete it.

and the option of enabling oem unlock in sitting is greyed and inaccessible.
[Mate 8 General] Georgian51:
Have you tried to block and unlock the bootloader? Once you unlock bootloader try to install twrp through fastboot. fastboot flash recovery_ramdisk xxxxxxx.img
[Mate 8 General] Leo_83:
Just out of curiosity, given the discussion about oem unlock I went into developer option to see what mine was set to but I couldn't even find the setting... I'm on NXT-DL00 8.0.0.829
[Mate 8 General] Georgian51:
That's exactly the problem, the Chinese versions do not have this option. He's gray because he installed the wrong firmware
[Mate 8 General] tarekcod:
exactly.

and since the L29 still on nougat i can't downgrade.

so

availables solutions are :

1- get the FRP key and unlock it via fastboot then unlock bootloader.

2- flash with tool that use Dload mode (dc-phoanix.....)
[Mate 8 General] alexito696:
I had a similar problem going from the Chinese version (DL00) to international (L29). I could not unlock FRP. The solution was to update to the latest version and enter my google account. Once introduced, make a factory reset from settings, not from the recovery. You can only unlock frp by entering the previous google account, and factory reset from settings. When updating you probably suffered a factory reset from the recovery blocking frp. luck.

---------- Post added at 08:45 PM ---------- Previous post was at 08:40 PM ----------

Don' forget usb debugging in developer options
[Mate 8 General] tarekcod:
that means i have to wait until the oreo or pie update comes for the L29.

:mad::mad::mad::mad::mad::mad::(:(:(:(:(:(
[Mate 8 General] M.abdo:
Did you try erasing using google device manager website? It should erase and delete your google account
[Mate 8 General] tarekcod:
the chinese rom had google service disabled.
[Mate 8 General] onedial:
Is that still coming? I have given up on it.
[Mate 8 General] matthewtech770:
Me too my Mate 8 is sadly sitting in the drawer boxed up :crying::crying::crying::crying::crying:

It's still my daily driver, so I keep it with me at all times.

Maybe it's time to upgrade.
[Mate 8 General] A.lemane:
So ...?
[Mate 8 General] rifad20:
I have upgraded to dl00 Oreo from l29.. How come there is no face unlock

Also, is there anyway to install new Kangvip ROM.

[Mate 8 General] lvrksn:
Hi. I want to see if someone can help me.There is the deal: i have a huawei mate 8 nxl-l29 dual sim.The problem is that when i try to make this tutorial and i debrand my phone to al10(single sim) i have only signal in one sim and the real problem is that i cannot have 4g because its in the sim 2 that i have signal and it only supports 2g.I know that i can debrand my phone to tl00 or dl00(both dual sim),but i've read that they are for chinese carriers only.If i debrand my phone to some of these models,will i be able to get signal or its attached to the rom i install?.thanks!!
[Mate 8 General] Georgian51:
The best for L29 is DL00. You do not have to worry about the signal. It works perfectly. I am from Romania and it works perfectly. Install Oreo on DL00 because it's worth it. Good luck
[Mate 8 General] lvrksn:
let me explain myself better. I bought this phone through eBay and it said that it was an l29. in fact when I got the phone it was a tl00 debranded to l29. it doesn't change anything right? thank you very much for you answer
[Mate 8 General] Georgian51:
It really does not matter what model it was. If it was original L29 works successfully at DL00. Any version was successfully going to the DL00 without any problems
[Mate 8 General] lvrksn:
thank you. how did you debrand to dl00? if I'm not wrong you can only debrand to al10 with srk tools. sorry if Im making too many questions
[Mate 8 General] Leo_83:
See above..
[Mate 8 General] lvrksn:
awesome, thank you. last question. where can I find dl00 OEM backup? I suppose that the twrp for nougat I will have to install it via fastboot, am I correct? thank you very much!!!
[Mate 8 General] Georgian51:
Above are all the information you need
[Mate 8 General] lvrksn:
thank you very much for your detailed install procedure, but I don't know if I'm blind or too ignorant, but I can't see where can I get the DL00 OEM info. thank you and sorry!!

[Mate 8 General] apat26:
Thanks dear. Is this the same TWRP from the chinese site link posted above?

Also, since you are able to pull from Chinese site, can you get links of the below too? It is for wake to unlock (this we don,t have) and face unlock (this we already have). Thanks in advance.

https://cn.club.vmall.com/thread-17216715-1-2.html

Also, if you scroll in the link below to second post, a method of decrypting data manually is given. If you can see that and tell us. I know we can simply decrypt the data through Chinese recovery for Mate 8 posted before. There we have option in advanced menu to just swipe and decrypt. But if this is something even easier.
[Mate 8 General] lvrksn:
I found the recovery on a spanish page,not sure if its the same that is given in the chinese site,Only thing i can say is that works flawless for oreo in the mate 8.i've used it to flash some open kirin roms and the basic functions at least worked with absolutely no problem,but since i am a compulsive rom flasher ,i'm now on stock emui rom,waiting for new roms,so i dont have the recovery to answer some of your questions.
[Mate 8 General] ceriqdesign:
is it decrypted?

Edit: i've flashed the twrp from link given by you..it's the same with [MENTION=7669718]apat26[/MENTION] gave before this..manually need to decrypt data..
[Mate 8 General] apat26:
So you dont have option in advanced menu to fix decryption in this recovery? I think it is there. You just need to swipe that option n if it shows as successful, you are done till you flash again a stock rom n factory reset.

Kangvip B835?
[Mate 8 General] apat26:
Only, on B835 Kangvip, face unlock bug is there for which you need to install apk for face unlock. Rest all good.

Here is the baidu link for Kangvip B835. I know B835 is universal . Universal means can be installed on DL,TL, CL, AL.

https://pan.baidu.com/s/1T-dJe1WmmL5A52MRr5TUTg

Here is the link for face Unlock apk: After installing, just give root permission and click on it. It will reboot and auto install and then apk will vanish.

Dload will not work. You will get update pushed to your system updated through FF and from there you can update.

Hallo

Ich habe heute am Abend das Update mit der 584 bekommen! Mit Sicherheitspatch von September!

Im Changelog steht, das NFC, Dual Window hat nun auf den Karten Symbole bei fähigen App, Telefonmanager/Reiniger wurde überarbeitet, Schnellanrufe optimiert, Bildschirmrecorder nun ohne Zeit limit, Galerie/Bildbearbeitung/Filter verbessert, und der aktuelle Sicherheitspatch vom September! Ich bin sicher das Oreo in 6-8 Wochen auch hier sein wird! Es wurden so viele in Europa verkauft, das es nicht oreo bekommen soll, wie alle anderen Ausführungen, wäre unlogisch! Da das L29 bisher aus meiner Beobachtung immer erst als letztes OTA Updates bekam, wird es auch Oreo als letztes erhalten.. Das dauert also noch ein paar Wochen, da die 584 auch heute erst kam, obwohl sie schon seit Monaten verteilt wird! Ich bin beruhigt, und warte mal ab! Ein neues X8 von Honor oder das 10 wird es dann zu Weihnachten ablösen!! Und es läuft rund wie am ersten Tag, ich hatte noch kein so gutes Handy.. Mag es nicht abgeben.. Mal abwarten wann noch Oreo kommt... Dann ist es perfekt für sie Rente.. ???

Mfg.. Micha

mate 8 twrp

Hello, twrp for emui 8 did anyone try?
[Mate 8 General] KaRLiKCZ:
I probably won. At the moment I flashed only TWRP (3.1.1-1), but at least progress... (It isn't not TWRP for OREO! I just unbrick it.)

Solution: fastboot oem lock ***passcode***

You just need to unlockit again. Even fastboot is writing unlocked, phone is LOCKED ...

I used the same passcode which I used first time when I was unlocking phone in 2016.

PS: I will ltry to install OREO when twrp is installed and booted :)

PPS: Installed OREO and working. I had small problem with syncing contact from Google, but OK now. At the moment I not happy, can't find root possibility. Do anyone know how?

plz let us know the progress and how well does it perform on mate 8!
[Mate 8 General] SunnyChinese:
Hi, guys. when i flashed Oreo, i find that the phone is relocked,then i use adb to unlock my phone, it is failed. so, i cant flash AOSP. i have no idea what to do.
[Mate 8 General] apat26:
I am able to unlock. Just check if you have activated developer options as sometimes it will again get closed soon as you activate it.
[Mate 8 General] SunnyChinese:
I am sure i opened it, i also colsed phone retrieval.
[Mate 8 General] ericjwg:
others are able to unlock it. maybe because model issue?
[Mate 8 General] apat26:
My question is even if you are able to open it, how will you flash AOSP till we have TWRP for OREO available.
[Mate 8 General] jbmc83:
maybe it could be possible to flash the partitions individually via fastboot or ADB sideload...
