Rollback Android 6.0 M to Official Lollipop B200 - Huawei P8 Guides, News, & Discussion

Hello,
Having a lot searched the net looking for a "rollback" to the official Marshmallow B200: I found a German tutorial.
Warning: my phone was unlocked bootloader ...
Original link: http://huawei-info.de/p8-mm-rollback
1 - You have to download this file:
http://huawei-info.de/downloads/GRA-L09Rollback.zip
2- Unzip and as always, set /dload and load it with Vol + and Power
3- Download full B200 I found here for Europe
https://mega.nz/#!nc8gRbDT!2ILh8A7BDA8Qxt0cjA_L-FsWyKTzyzJWuMDOcH-6yOA
4. Unzip and as always, set /dload and load it with Vol + and Power
Data is lost because of factory reset done alone
And miracle, my phone is income B200!

Does the bootloader has to be unlocked?

Since we're talking about original firmware, no, you don't need to have an unlocked bootloader. You are safe, since 6.0 has no custom recovery or root. At least for now.

*FIXED* No OS installed no backup, install stock rom with TWRP *FIXED*

**UPDATE RESOLVED**
For anyone who searches and has same problems.
I needed an sdcard to get the files onto the phone.
To recap - it was stuck in boot, TWRP would load and stated no OS installed.
1. In rooting guide as per Here download file linked in the guide and unzip.
2. From folder 3 of that zip file there is a folder called data containing stock.img - place this onto sdcard.
3. Then go to this thread and download the files as hosted on mega.nz - over 2 gig.
4. Extract that zip to the sd card so that on the card is a folder called 'dload'
5. To confirm, the dload folder should have update.app and 2 folders called dt and hw
6. Put sdcard into phone.
7 .Boot into TWRP
8. Goto install, select storage, select your sdcard then select stock.img, agree to install, ignore message about no os.
9.Once that has installed my phone just restarted, EMUI came up, read the dload folder automatically and ran.
Then once phone started it found a newer update and installed that.
Phone is now working, unrooted and bootloader is locked again.
All this was found on the XDA site, just across various posts.
Thanks again to all.

Hi all.
Please help, I'm a ****!
I unlocked bootloader with Huawi code from thier website.
Then I installed TWRP
Which in turn installed SuperSU
All rooted, jobs a fish. as per - This one and This thread.
Decided I dont need root anymore.
Tried to reset and wipe the phone.
Went into TWRP did a factory reset wipe.
Then went into TWRP again and did advanced wipe, and selected everything.
(yes yes i know, what a tit)
So after that i get the 'this phones is unsecured' message, press up vol 3 seconds, press power button to conti, wait 5 seconds etc.
so I wait, and it sticks on 'Your device is booting'
Restart, can get into stock recovery and hisuit will see the phone and try to restore it but fails and say my device is not supported??
Can get into erecovery and connected to wifi to try and update but does not find anything to download.
can get into twrp.
I have downloaded a stock rom as per -- This ROM
Perhaps this is not the correct ROM, but then how do i find out the correct ROM needed now I can not access phone details?
Forced that onto SD card but TWRP will not run it and says it is corrupt.
I can see it with ADB and device manager so my question really is....HELP??
How can i get just stock rom back onto it and then un-root and re-lock the bootloader?
Cheers in advanced.

you can find the model (for me it's vns-l31) on the back of the phone, just find the corresponding oeminfo file and the update file. flash the oeminfo file, put the update file from the rom zip in the dload folder and reboot using the 3 button combo till it says something about installing update
here's a list of update files: https://forum.xda-developers.com/hu...huawei-p9-lite-firmware-compilations-t3517124
and here you can find the oeminfo files, there's a google drive link under oemfiles, at least for the vns-l21, 22 and 31: https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873

Hi, thanks for the reply.
All of those links refer to the P9 Lite - is this the same internals and software as the normal P9?
On the back of my phone it has - Model- EVA - L09 FCC ID: QISEVA-LO9 - IC: 6369A-EVALO9
I do not see how this relates to specific oeminfo file?
Lasatly, can you provide details on how to flash the oeminfo file to device and do you mean the following for the update:
So in rom sip there is a update.app file - extract this to sdcard in a new folder called dload? then install that via twrp?
Cheers

first of all, no, p9 is a different phone, but you posted on the p9 lite forum. i'd suggest posting this question on the p9 forum.
i don't know exactly how it works for the p9, but it shouldn't be much different.
for the rom zip: inside that zip there's an update.app file, that file should indeed be put in a new folder called dload, but it won't be installed through twrp.
on the p9 lite it works like this: you flash the oemfile through twrp, and after that push and hold both volume buttons and the powerbutton till the phone reboots and shows an update progress screen, then you can release the buttons. now the update file will be installed. but then again, i don't know the procedure for the p9 so be sure to post your question on the correct forum.
edit: i've taken a look on that link to the stock rom you tried installing, it's a zip file that contains the dload folder, just put that folder on the root of your sdcard. do make sure it's the correct version.
you will have to flash the stock recovery for your phone however, and if the p9 works the same way as the p9 lite you should find an oeminfo file and flash that with twrp.
So sorry, I didn't realise I was in the lite forum!
I'll ask a mod to move, sorry and thanks for you help.

here's a link to the oeminfo for eva -l9: https://forum.xda-developers.com/p9/development/c432-oeminfo-flash-twrp-t3384903 i think that one should be flashed in twrp, and after that you can use the 3 button combo
no problem at all

After flashing the 1st file I'm stuck on Huawei logo! I can't enter eRecovery or any other thing except fastboot & Rescue mode and I can't seem to flash anything else even using fastboot commands it keeps on giving me failed remote command not allowed and I have installed all the correct drivers. please help my phone has been useless for the past 2 days!
I tried Volume up + power nothing happens just vibrates twice and then goes back to boot logo and stays there.
I tried Volume down + power it goes into the white screen but when I try with Hisuite it says your phone isn't supported and when I used programs like SRK Tool it can't flash anything always returns error command not allowed.
I tried putting correct update.app on SD card and using Volume up and down + power button but it just vibrates twice and never goes into the recovery window!! All this happened after I flashed the 80MB file for L31.
I wasn't rooted before I was on N from the OTA update and wanted to rollback to MM

You can try this method from @Chisetdel31260, try putting EMUI 4.1.1 in the dload folder (the latest ROM for your device) and then it reboots to eRecovery, then you boot to recovery and select factory reset.

AL10 Can't get OTA to work

I have an AL10 with Chinese firmware. I used SRK Tool for Huawei and did the following
1. unlocked booloader
2. install twrp
3. Flash L19C646B190 from twrp
4. root
5. update oeminfo to C636
- After this step I had issues that when I boot the phone kept on asking for a password to decrypt the storage. I booted into twrp and tried to change the /data partition to ext4 from f2fs, but couldn't
6. Tried to flash L19C646B190 using UPDATE.APP and volume up + volume down + power, but couldn't. Phone complained that the firmware was incompatible
7. Used SRK Tool to update ro.build.display.id to EVA-L19C900B00. It was #ro.build.display.id=disabled
8. Flashed L19C646B190 using UPDATE.APP and volume up + volume down + power
9. Bootloader was locked again and twrp replaced with stock recovery after flashing
All in all the phone seems to be working find, but OTA is not working.
How do I go about getting OTA to work again?

Worked like a charm, thanks I changed my oeminfo to hw / meanaf for c185 and flashed an offical L19C185 from Huawei. Immediately got all the OTAs and the device is working great.
For anybody with an AL10, don't bother looking for a L29 ROM, just Flash n L19, it works perfectly. The OS sees all the RAM and storage space
I flashed L09 rom to my AL-10 and everything is working fine too
I also have an al-10 and I'm tired of the Chinese rom.Can I change it to another rom?

[TIPS] Revert Custom Rom to Official and untouched - Hard restore

Hi!
I see the large number of requests concerning the roolback of a custom rom to a official and untouched EMUI 4, i decide to create this thread.
After follow that methode, you able to rest on official EMUI and get the new update automatically on OTA (directly on your phone) OR try to install custom rom with a clear and good base version.
1. You ave access on TWRP?
-If not, pleas unlock your bootloader (again) and flash TWRP recovery for you actual version (marshmallow or nougat).
-perform a full wipe and restore your partitions on "ext4" format, shutdown phone.
2. Get a "oem_info.zip" for your model phone (dont extract the .zip) and push it on your internal or external sd.
-This archive contain cust and oem info for patched your phone at the correct manufacture information.
-I have a link for VNS-L31 (c432, but is not very important) HERE LINK
-If you have other model (VNS-L31) pleas find a correct patch for you (VNS-L21, ...).
3. Find and download a EMUI marshmallow official full-ota update.
-for a VNS-L31 i advice choice a VNS-L31C432B160 full-ota update.
4. Unpack your update archive.
5. Create "dload" folder on your internal or external sd and put it UPDATE.APP
6. Reboot phone on TWRP recovery and flash "oem_info.zip"
7. Use dload methode for update (hold 3 buttons phone and dont release before "dload screen" appears)
8. Unlock your bootloader again (important!) And make a factory reset
9. Your phone reboot (please wait ) and done!
Ok now you are on official version, please update on setting menu >> update and choice, rest on official or flash a custom rom..
P9 lite brick precision:
In my personal experience the "p9 lite" is very easy to flash, mod or other tips and the risk of HARD brick is very very tiny.
If you see this page and your phone bootloop, relax, keep calm at 99,999% you have a little and ridiculous brick
Good luck and flash happy!

Update: I can now reach point 7 but now won't do dload (3 buttons) method... Huawei logo all the time. Can't even turn off the phone
In my other thread you post the same problem but is not entirely the same..
You succeeded to enter on fastboot mode? Flash recovery?
If you follow the steps 1-5 is impossible to fail the 6 point..
You have acces on fastboot mode or not?..

I did update the post... 3 hours ago I wasn't able to enter TWRP, some way I did managed, now I can enter fastboot, I did flash custOEM (sorry I don't remember exactly the name but it's the one of your post) .zip file. Now I can't do dload method, stuck on huawei logo. If I try to go to recovery, I got red message "phone fail validation"...
I know, I post on both but I was trying to do everything...
just tried... validation red error message won't let me go to TWRP now...
You have a VNS-L31C432?
Your phone does not enter at dload mode?
Wipe all partitions an retry flash a oeminfo for your model phone (if not C432 you need right oeminfo).

How can I wipe all partitions if stuck in Huawei logo? Is there a way to do everything from adb command line? (I'm using Mac and cannot use all the tools I've found here XDA neither hiSuite which is basically a backup photo/video only the Mac version).
Thank for helping, really appreciate
To answer your question in the other thread, yes bootloader is unlocked and I am on C432.
What's your rom have before the bootloop?
You have the right version of TWRP for your rom?
If you have a MM version Don't flash a TWRP for N.
Send me a link to TWRP version used (thread forum)

Before the bootloop I was on L31C900 (on the phone) but I did actually flashed C432B160 because I did rollback. TWRP used I've found in the other post where there's a OEMfile to flash (but for this I need to double check because I did look so many pages which I am not 100% sure.
I not have experience on other model that C435.
But i suggest to find a oeminfo for your variant (C900?)
For TWRP you need flash a version for MarshMallow HERE
Flash it and pas return here (fastboot flash return and first enter to new recovery)
Hi, found Windows emulator for MacOs so I extract from update.app boot.img and flash.
I did format all partitions as told using a proper twrp this time.
What's next step, system says NO OS INSTALLED?

Flash partitions on .img files is not needed.
Just find a corect oeminfo for your model phone.
Flash it on TWRP recovery.
Use dload methode to update on basical version (MarshMallow b160).
After that, unlock bootloader again and make a factory reset.
Switch on your phone (the first boot make long time).
Update on last emui on OTA.
Done!
After that you able to install a custom rom.

Thanks again you're saving my life!
IT won't turn off so been always on it won't keep the charge... Writing so because apparently it won't go to download mode (dload) if plugged in. On the other way if I unplugged from power it won't even start. Shall I force to download mode using console ADB or FASTBOOT? I had looked but can't find anything...

I not understand.
You not able to switch on your phone without connected charger?

Correct. Because I'm not able to switch it off it won't keep the charge. When discharged, the minute I do plug on charge it wakes up... That's the loop...
My main question is: does a command exist to enter download mode using terminal?

You have a hardware bug?
No abd command to enter dload mode..
Try flash a update.zip with twrp (not guaranted)
After that unlock bootloader again and make factory reset.

Hi, I followed this guide to go back to stock from elite rom. I flashed my oeminfo.img on twrp and then went to dload combination. Do I have to unlock the bootloader after the reboot? Thanks!
Hi,
I followed your guide and it works perfectly thanks!

[GUIDE] Downgrade from EMUI 9.1 to 8.0 for bootloader unlocking

Hey guys.
I was on EMUI 9.1.0.166(C675) which is the May 2020 security update and I wanted to unlock my bootloader which is only possible if you are on EMUI 8 with a security patch of June 2018 or below. There was no option in HiSuite to downgrade as well. I came across many users not able to find the right firmware to flash for their device. So I made this guide to help them.
These are the details of my device before downgrading
Model Number: LLD-AL10
EMUI Version: 9.1.0.166(C675E6R1P4)
These are the firmware I flashed in order to reach the desired version in order to unlock the bootloader.
1. EMUI 9.1.0.112(C675E4R1P4T8) https://androidhost.ru/1lau
This firmware should be flashed via dload method.
2. After successfully flashing this. You can connect your device to HiSuite and then you'll get an option to switch to EMUI 8.0.
3. Then flash EMUI 8.0.0.194 via dload method again https://androidhost.ru/29Fa
4. Finally flash this firmware version via dload. Click here
P.S You can maybe skip step 3 and directly flash the firmware in Step 4. I don't know if it'll work or not.
After flashing the 4th firmware, your device may bootloop and go to erecovery. This is completely fine. If it goes into erecovery just wipe the data/factory reset and you're good to go!
Hope this will help you guys!
will it work on LLD-L21?

I don't know but you can try! It's perfectly safe because even if the firmware is not compatible it will just say update failed. Nothing will happen to the device.
Not works on HONOR 9 Lite LLD-L31
I copied firmware files in dload folder and used volume + with volume - with power button. But it says update failed

The dload folder will already be in the zip file downloaded. Just add it to the root of sd card and update. I didn't use the volume button method, I used the manual software update method by dialing *#*#2846579#*#*

Hi, Instructions are not clear. Can you please provide excat directory to save the files on memory card?
I have tried placing the zip file on memory card. It says 'No upgrade file'. I've extracted and placed the dload folder in memory card. Then it says 'update failed'. No matter how hard I try, I'm not able to apply the update on step 1.
Hello. I have been following your guide on unlocking honor 9 lite bootloader. I reached till step 3 successfully. The firmware in step 4 (google drive link) is missing. I want to unlock my honor 9 lite and your guide seems to be quite helpful! Hope you will correct the drive link. Thankyou!
Hey majid, can you tell me which file do i need to copy to the root directory of the sd card as there are many folders in the dload folder in the rom you provided.
I am confused.
1. As i extracted the zip there are 1 folders namely release doc and software
2. In software there is dload folder and in that there are other 2 folders namely LLD L22A and LLD L22C and an update zip...
What is the next step .. kindly reply.
Hello, anyone have the 4. link (google drive link is down) ?
Thanks
