All fixed and running .311 after a day of use, it's a bit snappier, scrolling is smoother, better memory management by a long shot.

Not sure if I did something odd or if it's a known issue using emui flasher method but my phone was encrypted and fingerprint still enabled, had to do a reset/restore to get screenlock/pin to work

Would it (theoretically) also work the other way - i mean with rollback to 9.0?
[Huawei P20 Pro Guides, News, & Discussion] Pretoriano80:
Yes, but it would require a valid roll-back firmware.

And of course, the root part can be skipped.
[Huawei P20 Pro Guides, News, & Discussion] forever_lol:
That's what i thought.

Currently it looks like we have "incomplete" rollback versions on ff (packages contain only full base files). My guess is we would have to combine it with hw_EU_update package (taken from the previous versions e.g. 195). However i am not brave enough to test it myself :)
[Huawei P20 Pro Guides, News, & Discussion] silverstream:
Will it works with 320 single update_full_base.zip?
[Huawei P20 Pro Guides, News, & Discussion] Pretoriano80:
It might, but i don't have a P20 Pro, so i didn't tested personally.

Best would be to test with B320 + Cust -+ Preload.
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
Nice work thanks but never mind it's all done now. Stock no root and updated just as I wanted. With the obligatory minor hiccup but emui flasher worked perfect, not sure what caused the hiccup as no one else seems to have had the same issue

[Huawei P20 Pro Guides, News, & Discussion] Pretoriano80:
Probably you will need C636 base,cust and preload.

For C432 these are the correct cust and preload :

update_full_cust_CLT-L29_hw_eu.zip

update_full_preload_CLT-L29_hw_eu_R1.zip

[Huawei P20 Pro Guides, News, & Discussion] Pretoriano80:
What do you mean with "extract"?

Well, there's always a risk with this stuff, if you want safety, then better wait for official OTA updates.

To fix eventual issue, there's a tool similar to the one i use for updating to 9.1.
[Huawei P20 Pro Guides, News, & Discussion] silverstream:

Hi.

Currently I am on 9.1.0.311 and to be sincere, I don't find any differencies in speed than previous builds like 9.0.0.295. Since this new EROFS file system, root is not really possible (at least not yet), I would like to go back to 295. It is possible to downgrade to 295 using dload?

I got tired of waiting and ended up making a mess, i then fixed it (made a guide in sig how to)

Now i don't get any updates, stuck on 190

Firmware 9.0.0.190 (C432e5R1P9)

EMUI Version: 9.0

Device Rebranded L29 (from L09)

Variant: C432 (from 783)

UK Phone from EE

Unlocked bootloader

HiCare offers no updates

System update offers no updates

Have no idea which one to download, have no idea what tool to use, or even if i got lucky with the last time, I had an update.app file but it was missing userdata.img so it just didn't work (flashed all img's one by one via fastboot)

Can someone point me in the right direction please? Soz man i feel like a total noob even asking, just don't want to commit and end up having to troubleshoot my way back to normal, was touch and go last time.

Think i'm getting old :eek:
[Huawei P20 Pro Guides, News, & Discussion] Pretoriano80:
Probably the best wau is to first update to a higher EMUI 9.0 version and then upgrade to EMUI 9.1.

For the EMUI 9.0 you could use the dload method (this method might wipe the data and lock the bootloader, so if you are comfortable with the wipe, then make sure you have the bootloader unlock code.

Here's a service firmware for the dload method - > https://androidhost.ru/1L3J

Another way to update your EMUI 9.0 is to download a FullOTA for your model and brand (CLT-L29 C432) and flash it with EMUI Flasher tool (this method requires roit)

After that, you can upgrade to EMUI 9.1. You can find all the methods here, in this same thread.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Thanks man :good::good::good:

So get my 190 up to the latest actual 9.0.0 variant and then commit to 9.1.0 ?

I don't fancy the bootloader method, don't think i have the code anymore, can't remember if it came in email or not.

Root isn't a problem.

EMUI flasher tool, crikey, never used that, i'll have a look around, appreciate the heads up man.

Cheers.
[Huawei P20 Pro Guides, News, & Discussion] otonieru:
EMUI flasher by oldroid is pretty stable and dependable. Been using it for upgrading and downgrading without losing any data,

Use ver 1.2, it can go directly to 9.1
[Huawei P20 Pro Guides, News, & Discussion] Pretoriano80:
If you don't have the unlock code, then probably it's best to avoid the dload method.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
ok cheers.

I'm just trying few things before i commit, thought i could maybe spoof my location using smartdns to get the update to push through :) yea i know.

---------- Post added at 04:42 PM ---------- Previous post was at 04:39 PM ----------

Where are you actually obtaining the said firmwares from yourself? And what are you looking out for ?

Seems there's a lot of numbers and letters after the L29 C432 and version ie: 9.0.0.190 for example.

Do the rest of the letters matter?

So confusing man.

Thanks to you both btw, really appreciate the help, it's not the most straight forward of tasks i've had to do.

---------- Post added at 04:51 PM ---------- Previous post was at 04:42 PM ----------

Are you sure about the direct to 9.1 mate??

It might work without issues or it could fail, i don't know. Most people updated from higher version, but that doesn't mean that it doesn't work from B190.

Very very last question............ :(

What about this one??

https://support.halabtech.com/index.php?a=downloads&b=file&id=145556

Downloads are quick for me, i think this should be ok.

Not sure i like the word BAD in the firmware name though.

---------- Post added at 05:58 PM ---------- Previous post was at 05:31 PM ----------

ok so tried to install the update via flasher tool, but it's failing, says verifying then says installing up until 4%.

Then reboots and loops.

The phone is booting with the previous stock rom so all is well again.

Still rooted.

The full OTA zip i have has two folders in it, one called

update_sd_CLT-L29_hw_eu.zip which is 1.18GB

the other is update_sd.zip which is 3.08GB

I selected the first one as it has the name of my phone in it, then the flash tool was asking for a second file, so i chose the update_sd.zip and then let it rip.

Guessing i didn't do that right.

If i just choose the update_sd.zip one it's non specific so that can't be right, hence me using the other.

Any idea??

Cheers.

---------- Post added at 06:15 PM ---------- Previous post was at 05:58 PM ----------

ok so i just went with the update_sd.zip

Stopped on 5% then went off, thought it was looping so tried to force a shutdown.

Now the screens white and it's saying installing update.

It's either working or something very very wrong has happened

Terrified to force a shutdown now so i guess i'm going to have to wait and see what happens.

Anyone chime in please, i'm getting worried now.

[MENTION=2642882]Pretoriano80[/MENTION] [MENTION=4066277]otonieru[/MENTION]

Been on 5% for about 5 mins now, hasn't moved.

Shall i force a shutdown??

update: it rebooted on it's own. Got me back to the device, so it's actually functional again, need to get this right next try.

UPDATE: OK i think i found a new way of updating loooool.

I moved both the zips to the root of my internal storage and when the update failed with the flash tool, i tried to reflash TWRP so i could re-root (for some reason i lose root if i don't try to boot to recovery (recovery_ramdisk is where magisk is installed for me, a normal boot doesn't allow root? no idea)

So when i flashed TWRP, then booted to it, once it loaded it recognised an update zip on the internal storage, then it installed it without my interaction, i couldn't stop it and didn't want to pull the plug.

So i allowed it and let it boot.

Expecting the worse when it booted, i checked about phone.

Build number: CLT-LGRP2-OVS 9.1.311 GPU Turbo

EMUI 9.1

Seems to have worked??

Crazy.

Hope this helps someone else who ends up in the same boat.
