Hi everyone, in order to use all of my favorits xposed modules, i want to go back to android 6. I found lot of guides for rollback but my problem is Im on twrp, root and with a unlock bootloader. So i don't know how to proceed.

First you must flash stock recovery. You can extract from another full rom 7.0
Second you must have downgrade pack for your region and mobile operator.
Next you must have full rom 6.0 for your region.
You must have all file because you don't want debrand your firmware

Thanks, actually if i want debrand my phone whats the diference? Because I think I don't care...
Also, where can i find all of these files you write about?
I'm really lost with all firmware versions ... Does it matter if my version is EVA L09 C33B363 and i flash stock recovery from another version??
Also, my bootloader is locked, do I have to relock it? Does it even possible??

If you have locked you must unlock again. All file you can take from forum. Debrand it's unlock warranty and sometime you loose your guarantee. But what region you from

Here you have how debrand
https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
If you debrand you can then flash stock recovery flash b300 and then b136 and do it wipe in stock recovery.
When you want debrand first you see your cust be c900 and then you must flash stock recovery do it wipe system/data and cache
If you do it your cust change to c432 and then must check your region using dial pad
*#*#2846579#*#* then push 3 and 4
If you see your vendor: hw and country: Europe
You can downgrade to b300 and then to b182
You lose your theme and you see ugly icon then do it wipe system/data and cache in stock recovery
After this you have update to b383 then b386 next to b391 and final to b393 or b394
I have b393

HELP! Stuck on EMUI welcome page

So I did a hard reset after relocking my bootloader in order to install my new update (EVA-L09C150B375). I successfully relocked it, then resetted it. However, after I turned it on to install the update and restore it from HiSuite, I was welcomed with the EMUI starting screen (language selection, T&C, wifi, google account) and I'm stuck there. The thing is, all my keyboards are lost and whenever I want to type in something, only the google voice button shows which I can't possibly use to enter passwords or pin. If I skip everything and 'set up as new phone', it brings me to the 'add fingerprint' scene which if I skip, I'm brought all the way back to the beginning of the WHOLE proccess (back to the EMUI logo), and I can't add a fingerprint because you have to give either a PIN or a password in order to be able to use it. I have Wi-fi connection but nothing else. I can't bring up any menus. When I do a hard reset, it bring me to this page again after rebooting. Is there a workaround? I'm completely lost.

First of all, unlocked bootloader does not prevent OTA - for OTA you must have stock recovery and stock boot partition (no root) but you can have bootloader unlocked.
Only thing - successful OTA may lock your bootloader back (depending if such a flag is present in stock update.zip or not) but again, you can safely start OTA with the unlocked bootloader.
Don't know why so many people go to relock bootloader before accepting OTA, which triggers hard reset and potentially troubles.
Did you at least leave OEM unlocked (OEM/FRP unlock also does not prevent OTA), that you can unlock bootloder again, install TWRP and revive your system by eg HWOTA method?
About missing keyboard - when you had your previous rooted system, have you disabled/removed Huawei default keyboards: SwiftKey and Swipe for Huawei - after hard reset it looks only for them, without them you have no keyboard...
Also, before hard resetting, have you removed fingerprint protection you have had?
Generally, if you removed fingerprint before hard reset, you should be able to skip setting the fingerprint.
I had a similar situation (no keyboard upun hard reset), and I was able to skip fingerprint, set-up a new system and then to install GBoard from apk on SD card and to continue.

I couldn't install the new update when I was unlocked, because it went into a boot loop. That's why I decided to start over with a clean page. I haven't disabled any keyboards and I haven't removed my fingerprint.

You couldn't install OTA not because of unlocked bootloader per se, but because of TWRP or root.
You better had to remove fingerprint before forcing to relock bootloader.
Did you leave OEM (FRP) unlocked (it doesn't affect OTA anyhow) - then boot to Fastboot, unlock bootloader, install TWRP and use HWOTA to flash complete firmware
https://forum.xda-developers.com/showpost.php?p=75787156&postcount=3
Otherwise, if you could get over fingerprint, boot to the system and install GBoard (download the apk on the PC or another phone and put it to the SD card)
Last option, rollback to MM and then upgrade by OTAs to the latest Nougat.

Okay, so I've tried b136 and b167 (the two most common in these solutions in this forum), and both of them went to 5% and then came an error message:
“Incompatibility with current version. Please download the correct update package”
I'm truly lost now. Any ideas? Should I try every single package for the L09?

Here is a proven rollback guide
https://forum.xda-developers.com/showpost.php?p=73448165&postcount=371
Skip steps 7-8.
In step 9 you should get OTA updates till b504 for L09 (b399 for L19).
Steps 11-13 are about rooting by SuperSU, not part of rollback.
PS: This guide is for L09/L19 c432 - if your phone was diff cust, you should rebrand or use b182 for your cust (not b182 for c432 as in the guide - you should look for the appropriate FullOTA-MF-PV build in Firmware Finder - MUST be FullOTA-MF-PV MM for your cust)

Will do, but I have one more question; how do I find out my model number(cust)? the box only shows the IMEI and that it's EVA-L09 and nothing else. I can't access phone details in the phone itself because of the original problem.

I see for my L09c432 in this file:
/cust/hw/eu/prop/local.prop
at the end:
ro.comp.cust_version=Cust-432000 5.0.0.1(0001)
You can probably (never did myself) copy it by ADB commands to PC and read.
Maybe you need to unlock bootloader to get access.
In that case you can also install TWRP and copy the file to SD card, and then open it on the PC
PS: I usually save screenshots to the cloud with Build info (About), IMEI, etc...

The guide you posted earlier worked! currently at b182, but haven't received any OTA yet (strange...). I'm now waiting for google play to update and install all the necessary apps though. Thank you, Thank you and THANK YOU!

So, is it normal that I'm now stuck on EVA-L09C900B182 ? Firmware finder is not working (not downloading, always getting error), and the stock huawei updater can't find any updates, so I'm now at emui 4.1.1. Will I receive those updates and should I wait, or should I flash from sd card the dload method?
Oh, and HiSuite also tells me that I use the newest update.

For OTA you must have SIM and must not be in Airplane mode.
It may take few hours or up to a day - it depends on your mobile operator.
Beginning of this year, last time I did rollback, I got b203 (if recalling correctly), then b383 or b387, then up to b398 (at that time).
Give it a try. Otherwise use DLOAD (use FF only for download), you must use FullOTA-MF-PV builds, only those work for DLOAD

okay, I'll wait til tomorrow. But the shady part is that even HiSuite can't find an update, what does my operator have to do with this?

I don't know how it depends on Huawei, ypur IMEI, SIM card... but once I was similarly waiting and both HiSuite and System Update told me I had the latest, and then same day later I got OTA push

Oops, sorry, I have overlooked that you say you are now on c900, not c432.
There are no OTA updates for c900
I assuned you have followed the rollback guide as above, didn't you - the guide included c432 b182 (not c900 b182), in which case you should have been getting c432 OTA updates

Update EVA-L09C900B182

I have a Huawei P9 that doesn't seem to receive updates.
EMUI 4.1.1
Build: EVA-L09C900B182
Andriod: 6.0
I have tried using firmware finder but I always get checksum failed before it passes 1%.
I had a look through the Forums and it seems that people recommend rebranding though that was in 2017.
I was wondering if there is any easy way to update?
I am a noob so i want to try avoid rooting and rebranding if possible.

Has anyone managed to update this?
2 years later and I'm still trying...

For c900 there is no newer firmware.
Flashing anything else than c900 means rebranding - but rebranding requires unlocking Bootloader (not 'rooting')
So wandering, what are you really trying to do for two years?!
- Unlock Bootloader (4 Euros):
https://www.dc-unlocker.com/
- Rebrand properly to be able to update to Nougat eg EVA-L09c432b504:
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2

I followed that guide but now my phone is stuck on "Type the password to decrypt storage" when I enter my Google password it says it's correct but data on my phone is corrupted. Any ideas?

Are you talking about TWRP asking for pass or Android?
If Android, on which firmware are you, what was the last step you performed?
Also, make sure you used TWRP for MM, not for Nougat - since you were on c900 MM when you started with rebranding to c432 (?)
Btw, you unlocked the Bootloader?

Thanks for the quick response and all your assistance. I managed to finally boot into EVA-L09C432B182 and will write what I did in the rebranding post for others who run into this issue. I still have no updates on L09C432B182 though.

For OTA you must have a valid SIM card and WiFi - check manually to the System Update to trigger checking for an update
You can also try with HiSuite (PC) - latest versions of HiSuite have an option at the bottom to update the firmware
See:
https://huaweiflash.com/how-to-flash-huawei-stock-firmware-all-methods/
You can also update by DLOAD (read the guide above), you must download FullOTA-MF-PV (must be PV), like b360, from Firmware Finder
There is also HWOTA method, see:

Hi! I don't know which version it's fine for your device and the only way to know it it's to flash it yourself, but i don't recommend you to do that.
Rooting with Magisk is fine on 9.1, just read the latest posts from this thread - > https://forum.xda-developers.com/mate-10/how-to/guide-magisk-root-mate-10-pro-t3886967/page27
As for the roll-back, ut should be possible to do it with this tool and an appropriate roll-back firmware (again, firmware version might depend on your cust/brand).
I recommend you to keep an eye and also read this thread - > https://forum.xda-developers.com/mate-10/how-to/firmware-version-mate-10-t3722019

B303 is not for A09, it's for C800 which is some jp cust.
Most new fw links are not up yet, and since Huawei decided to name all their firmware the same regardless of model its hard to know which is which :/

as stated before, since every update is named the same it's hard to tell which is L09, L29, A09 or AL/TL. AL/TL are easier as VERSION.mbn in UPDATE.zip doesn't have Global strings in it.
From what it seems, if you flash L09 on L29 or vice versa you get endless OTA updates for preload and cust. I don't know if just flashing the cust and preload zips fixes it, but you're free to try if you want.
Here's L09 preload and cust:
Preload: http://update.hicloud.com:8180/TDS/...full/update_full_preload_BLA-L09_hw_eu_R1.zip
Cust: http://update.hicloud.com:8180/TDS/...4//f1/full/update_full_cust_BLA-L09_hw_eu.zip
modified tool to include preload and cust:
https://mega.nz/#!oDR2DYCI!SRQlTq1IriGcEt1Wr--ggrBk7uZ4M_R8OwE6DdvmEEc
Extract and put in the EMUI 9.0 to 9.1 update folder.
Rename cust zip to update_cust.zip and preload to update_preload.zip, put in ZIPS-HERE folder, run modified bat.

Thank you very much, I try very soon. Have any of you done that already?

Perfect, also because I don't have the Root permissions on the device, and I don't even have twrp. In fact now I have tried and says that it does not find root permissions. Then I did not understand if the phone should be connected from on, in recovery or fastboot?

Tool updated. However, if you don't have root, you can't use it, you must root first.

Okay, I thought it was a tool like the ones we made earlier to install EMUI 9. I'll wait until the new tool is released. : D

Can I flash a Stock ROM without unlocking the bootloader?

I have a Huawei P20 Pro, CLT-L09, C432.
I haven't received the Android 9 update, I am stuck on 8.1.
I found a stock rom, just not Android 8.1 but 9.
I don't want to unlock my bootloader. Can I still flash this ROM somehow?

No, and there's nothing that you can do unlock it.
But you can update manually via dload option.
Im using the same model and its working great also gets ota after manually update to emui 9.1

Can you help me with that?

I created dload folder, and put the ROM in it. Got the code in dialer, selected software upgrade then sdcard, but my phone just says No sdcard.
Can you please help me with that?

You don't need to unlock your bootloader, you should be able to use firmware finder and hisuite to update, search for it, there are quite a few threads.

Well yes, I should be able. But I am not. I am hungarian, and the Huawei support informed me about the device being Austrian. I bought the phone second-hand, me and the seller neither knowing about it.
And they cannot update it unless I bring it to Austria.
OTA not working since I am 380kilometres away from Austria. HiSuite neither, HiCare neither.

Or is there a way of installing the ROM manually with HiSuite?

ROMs no, it's a full ota or nothing I'm afraid.
Why won't firmware finder and hisuite work? Ask in their thread.
