Success downgrade from oreo to nougat - Huawei P10 Guides, News, & Discussion

so...my p10 L29 was messed up after updating to oreo. i upgrade without rebranding, after that, my version shows bla bla bla(dont remember). after searching a lot on website (almost all of them), figure out that B217 firmware is the selution.
actually B217 firmware from ff finder has just 2 files, not 3. so using HWOT8 and change the update binary(with notepad++) you need go to META-INF>com>google>android>update-binary, open update-binary with notepad and delete the line with "echo - - update_package...... update_data public. zip.
after that copy the files to hwota8 > update file and make same process like you do to update.
after that, i rebrand my l29 to c432 and now all works fine:victory:

Huawei firmware finder by team MT is your best bet. It automatically searches different servers and gives you the firmware.
B350 is the latest update for your device.
But it should have arrived you via OTA already.
Check with HiSuite (or) HiCare app.
Update link - http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1046/g104/v60923/f1/full/update.zip
But since this is a zip file, I don't think you can update using this.
I'm not sure about the contents of the file. If the file contains only update.app then you can flash it manually.

Downgrade from B201 to B136 Possible?

I own a Chinese AL00 Honor 9,B201 is so poor,so I am intending to downgrade to B136,or B155.However in FF the lowest version I can find for my phone is B190:crying:
I verified the B136 for AL10 with IMEI,miraculously it passed,saying the firmware I will install is AL00C00B136.But when I finish the DNS changing I found I still only can get AL10C00B136.
Any idea on this issue is appreciated

Thanks so much!One question,will my bl be unlocked and lose my warranty?
Sent from my Huawei Honor 9 using XDA Labs
I handed over to the service in Poland with unlkock bootloader and there was no problem.
It depends on the service.
Normally your warranty is woid now.
How about download via FF and flash in the 3-button-mode?

Hi! what is the difference between B201 and B136 or B155?
BTW, I had AL00C00B201 flashed to L09C432B130, but it is very poor compared to AL00C00B201.
Now I want to go back to AL00C00B201 but I dont know how to do it...

Perhaps you need the HWOTA Rebrand method to AL00,I guess.Maybe you can use the B123 Service Repair Firmware but I AM NOT SURE
For the differences,they say that B201 underclock the CPU for better battery usage(ironically I didn't feel any improvement),but B123 and B136 aren't.I don't know about B155.So if you are a heavy gamer B201 may be a nightmare What's more B201 is in conflict with several Apps so they will evaporate into thin air after reboot...
Do notice that package for AL00 and AL10 are exactly the same.And the model number will be unchanged even flashing the AL10 firmware.I tested myself downgrading.And don't forget to wipe data.

If my mind is working properly,When it comes to select OEMinfo you can select to Rebrand to C00.All left to do should be replacing the EU Firmware with CN ones(can be downloaded on FF).I didn't try it so can't promise it's working

The B201 files is on FF with number"88860"or"88861".It is under model STFAL10C00.There are 3 files to be renamed after downloading.Then the firmware change should work technically.

I know this is about capacitive button fix but it should be exactly what you want.It contained the service Repair Firmware and a oeminfo_tool batch file which seems able to write oeminfo to CN and flash stock rec.It is also easier to use the 3-button-combo.

It is not that important due to the fact that AL00 and AL10 can use the same firmwares.I tried this method before and the model number did change to AL10 but nothing gets wrong.That time I didn't fully complete the guide.Seeing inside the package are separate folders of AL00 and AL10 I guess If the installation is done properly the model might not get wrong
Good luck!

You don't need to Wipe anything. Internal sd is mounted in /data which is not wiped.
Well, it's either that or use HWOTA to update.

Yeah, you'd have to restore stock Recovery, and OTA might install (it checksums partitions and if they don't match the update fails)

Sorry to revive such an old post but wanted to ask you how you used the flashy tool. Did you drop the 2 pie files into the "zips here" folder? Did you need to unzip the pie update files? Another post mentioned unzipping but maybe that was because it was a p20. Did you use the beta pie files or actual non beta files? Has it been able to get normal updates ota since then? Thank you

HELP TO UPDATE MY MATE 20 PRO (c212)

Hi, i have a mate 20 pro model c212 (at&t mexico), i want to install a new firmware for example c62 or c432, i can? or not? Pleas help me!
You could update main base easily, but that could screw the futur C212 stock OTA Updates if the new base version number you re flashing is not or won t be an official C212 base version number.
What is the matter with your LYA C212 ?
-still on emui9.0 and you want emui9.1 ?
-security patches date too old on latest C212 ?

And you know how to install an update if my operator does not?
You could use a service firmware to change cust, preload and base to a different region. I did this back and forth from C432 to C636 when I saw fit using the dload method.

Hm, when I used FH a while back it switched me to C636 - and every OTA I received was C636 - I couldn't return to C432 via any method until I tried dload and it worked for me. It may be because my device is natively C432.
I still don t understand how these previous FH updates managed to softrebrand just fine kirin980 devices.
Your build number once rebranded, in about phones, was then C636ExRyPz or you were missing the RyPz part?

Is it currently possible to do? For the bootloader issue, can you show me the guide you followed to flash?

There will be guides around on our device forum. But basically requirements:
USB Stick (formatted exFAT)
USB OTG
You will need to download the service firmware, for this I used androidhost ru and firmware 9.1.0.300 C432.
You will have 3 zip files inside the firmware, you must create a folder on the USB stick called 'dload' and inside this folder you put the three zip files (named like update_sd_base.zip etc). Plug USB stick into device with OTG adapter and then open dialer and type *#*#2846579#*#* and choose software upgrade then memory card upgrade. Should restart and upgrade device to your new firmware (don't unplug USB during this process and make sure you have above 30% battery)
I though he was speaking about how to softrebrand with FunkyHuawei...

Well if he was speaking about that then there's no guidance I can provide him. It's a paid service and doesn't really require a 'guide' as it's simple. He can check out their website, but regardless - if he wishes to try the dload method then there's there guide.

Included RP section, so it successfully rebranded, and then I managed to move back to C432 using dload.

So just to clarify, you're saying that you can rebrand a Huawei devices Cust code from example a C432 to C185 without bootloader being unlocked?

I'm in the same predicament. Previous owner flashed the firmware from C792 (Canada) to C636 (Asia) via FunkyHuawei. And now I'm not getting any OTA updates and stuck on 9.0.0265. I would like to re-flash my fw back to c792 and I have the bootloader unlock code for my device, but I'm unable to find any guides to help me achieve this. Will the guide you provided work for me as well?
