Best/Easiest way to update rooted P20 Pro? - Huawei P20 Pro Questions & Answers

There's been several updates I have been unable to install as I am rooted. Is there an easy way to apply updates? Can you unroot, apply updates, then re-root for example? I'm confused about what might be the way. I've seen the debrand thread. But you would still be rooted and therefore unable to apply future updates?
Any advise appreciated

I should have mentioned I am on EU (UK) version CLT-L09 8.1.0.103(C782). Not sure if this method will work for me?
I'll have a read through the thread though

Hurupdater is the simplest solution and I've never had any issues at all.
Did you rename the files correctly?
Did you download the correct files?
Did you put unofficial TWRP .IMG in same directory as the other files and renamed it?
So in total you should have 5 files in one directory. Then just flash hurupdater .zip file in TWRP. That's it.

What can be easier then flashing one file then simply installing an actual official update?
Hu isn't hard I agree but it's certainly not easier then flashing one file.

Yea just flash no check recovery and it'll overlook the twrp recovery when you install the OTA update is system update.
Obviously has to be an official update but that's all the tinkering that's required.
No check is in the files listed in my guide from my Sig.

Funky huawei by far.

[Q] Dowgrade FRG83d to FRG83

I updated my N1 from FRG83 to FRG83d manually few days ago and wondering if I can downgrade to FRG83 or even FRF91? There is not much to it than I just like to get the firmware downloaded through OTA. Just curious!
Thanks in advance!

Back up your apps in Titanium, then flash one of the images from here: http://developer.htc.com/ and you are essentially downgraded!

I have a stock N1, but since 2.2 backs up all my apps and reinstalls, I am not worried much. But will I just be able to download the zip file rename as update.zip and install manually? Also, will I get all the Google services along with the zip file?
Thanks for the response.
Try the FRG33 passimg from shipped-roms.

Download it to the root of your sdcard, rename it to PASSIMG.zip, and install. It will flash all the partitions on your device back to stock. It's a stock image...

Strange. Which one did you use? Try this one: http://dl4.htc.com/RomCode/Source_and_Binaries/signed-passion-img-FRG83_0923.zip
Maybe try renaming it as update.zip instead of PASSIMG.zip.
If that doesn't work, I'll give you another suggestion.

Yes, that's the one I used! And please don't get me wrong but I use this phone for my work and is important that I don't screw the phone. Is there a tested solution to downgrade? So I can follow steps without damaging the phone?
Check it's not a zip within a zip
Edit: I can give you a 100% tested (by me) downgrade solution. Unlock the bootloader, download FRF91 from http://developer.htc.com and use fastboot to flash system.img and boot.img

You will certainly not damage your phone by doing that, so don't worry. Rename it to update.zip and try again.

Looks like this is yet to be achieved. passimg.zip of FRG33 says main version is older and 'update failed!' error.
Any other leads guys? Mine is a replaced Nexus One and it has FRG83D on it. I want to downgrade and then root. Help much appreciated!

Looking for stock recovery to flash OTA

I need the stock recovery image (from 23.16.3.victara_retca.retca.en.CA) so I can flash the 6.0 update since it won't work with TWRP.
Any help? Google isn't providing me with much.
Does it have to be from the Canadian variant (not sure if the recovery images are different between variants)?
Tried looking here for the correct zip, which should contain the recovery image?

I have no clue. I doubt it would have to be the retCA version. I'm sure everything besides radio and system will be the same.
This is from the latest RETCA XT1097 5.1 firmware:

Worked perfectly.
My process
- Flash stock 5.1 using fastboot (Steps can be found on Motorola's site or somewhere on XDA)
- Install Marshmallow OTA
- Flash cracked boot.img for Marshmallow. This step is needed in order for TWRP to stick and for you to root without getting stuck on the warning screen. (I'll find the link for you if you can't. It's somewhere on XDA.)
- Flash TWRP
- Create backup so I don't have to go through this process next time haha

Awesome! Thanks for the tip. I got as far as the 6.0 OTA (RETCA), and am now trying to get root back again. Where did you find the cracked boot.img?

Something odd has happened since upgrading to 6.0.
'adb devices' still sees my phone, but 'fastboot devices' no longer sees anything, and making a desktop back-up with adb now creates a file containing 0 bytes.
Everything else seems fine. Are there some new permissions I need to give before this will work?
Thanks again.
Edit: I managed to get fastboot working, however now I've run into a new problem.
To confirm, when you say flash the cracked boot.img for Marshmallow, I should execute 'fastboot flash boot boot.img' for the cracked boot.img?
I'm getting the error: mismatched partition size (boot)
I can still enter TWRP with fastboot, but it's not permanent without the cracked boot.img
Am I missing a step?
Edit #2: Finally got TWRP to stick another way and have root now. Thanks for everything!

QA1 Update Package

Ok, so I have the QA1 package from AT&T, how to I turn it into something that Odin can use?

Is it the OTA update or the actual full firmware?
IF its just the OTA package, we can still use that, all we have to do is flash the preceding firmware with ODIN and then use recovery to flash the OTA zip.
Upon closer inspection, it's just the update package. I can upload it somewhere, but probably not necessary. Downloaded from here with a tip from another thread:
"C:\Program Files (x86)\GnuWin32\bin\wget.exe" --user-agent="SAMSUNG-Android" --no-check-certificate "https://xdmd.sl.attcompute.com/agents/42925/1488/SS-G900AUCS4DPH4-to-U4DQA1-UP"
How do I make this into a zip that can update via recovery?
edit: this is probably faster than downloading via Samsung: https://goo.gl/jGt7TO

Literally all you have to do is put ".zip" at the end of the filename. Its just a zip file without the extension.

It shouldn't... then again I had one OTA flash that half-flashed and then wiped everything so its a good idea to back up your important stuff
Bummer...wiped. Not a huge deal as I had a backup, but to anyone else following: this wipes everything.
Added QA1 - QB1 update here:

This WILL wipe your data when you flash this using recovery.

HELP: Upgrading to EMUI5 on NEM-L21 with TWRP and Xposed

I read here, somewhere, that you need stock recovery to do the update. Since I have flashed another recovery (and rooted and installed Xposed), I'm not sure if I can update to EMUI5.
Furthermore, I'm not even sure how to do the update. The update (b351) is available in FF and checks out as "compatible", but I don't know what the install procedure is. Especially without stock recovery.
Any help or info is much appreciated
yeah, you should flash stock recovery thru ADB and thn try updating...
Not adb but fastboot

That you may need to find your own. Well in custom ROMs, they are designed to work with custom recoveries like TWRP. While in stock, the whole system is inside update.app, which can't be read by a custom recovery.

Correct stock file for Indian Version LLD-AL10

I downloaded and tried flashing this one but got an error at 5%.
LLD-AL00C00B172 (8.0.0.172),LLD-TL10C00B172 (8.0.0.172),LLD-AL10C00B172 (8.0.0.172)
Can someone tell me which version i correct for me?
Does it match your device model? Also what was the last firmware you had on the device?
Sent from my LLD-L31 using Tapatalk
I don't remember the last firmware but the device is LLD-AL10
I file I tried was the latest I could find on the website. I just tried another file, got the same error.
Your device might be a LLD-AL10 however the last 4 digits is important.
For example you have :-
LLD-AL10C00B172
LLD-AL10C01B171
The C bit is the important bit. Also make sure you download the FullOTA-MF file set.

Not sure as my phone hasn't been unlocked or twrp'd. However if its like the LLD-L31C432 then your best bet might be to try LLD-AL10C00B163 as on mine i can't install LLD-L31C432B132 however i was able to install LLD-L31C432B130 or LLD-L31C432B131.

Holy ****! this worked with HuR tool. But the only problem is, its a chinese ROM, without play store. If you tell me what those 3 files were, i'll download the Indian version and flash it. Thanks a lot though
From what i understand its the following
1) Format an SDcard and Create a folder called dload in the sdcard.
2) Extract the contents of update.zip to the dload folder.
3) Place the SDCard in the phone.
4) Press and Hold VOL up VOL Down then the power button.
