[Huawei P20 Pro Guides, News, & Discussion] androidyeah...:
Yeah, I did that. Extracted the new ramisk and patched it, not sure what's going on.
[Huawei P20 Pro Guides, News, & Discussion] aka.petteri:
Nope. Do I need root to install it? Maybe I should try via OTG cable
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
I'm in the same boat. BL is unlocked however don't want to root as don't need it and causes problems on and off with some of my apps. Is there a no-root friendly method working yet?

And what is, if any, the difference between say .311lgrp2 and .311c431 versions..... Aren't they theoretically the same?
[Huawei P20 Pro Guides, News, & Discussion] argh9:
Anyone else having problems rooting 311? After flashing the modified recovery_ramdis.img in fastboot nothing really happpens as I have no root after rebooting
[Huawei P20 Pro Guides, News, & Discussion] bravo261:
if you flashed the correct ramdisk, you have to boot into erecovery and select the factory reset option, which doesn't reset the phone but will just boot it into rooted android. back up your stuff...its how my phone (kinda) worked. no promises!
[Huawei P20 Pro Guides, News, & Discussion] argh9:
Aha, I didnt do factory reset, but I guess it doesn't actually reset the phone right? It's just a fancy way of saying boot normally with root?
[Huawei P20 Pro Guides, News, & Discussion] mosaiques:
Even if you write "yes"?
[Huawei P20 Pro Guides, News, & Discussion] androidyeah...:
You have to type 'yes'. It will then reboot and you'll have root. There seems to be an issue for myself and some others here with root breaking messages and the phone however. I've patched the ramdisk every time and i've also installed the full update fiile on its own and also the two files using emui flasher. Every time magisk patched breaks messages and phone so im just using 311 without root for the moment.

I tried to flash back the unpatched ramdisk yesterday to try 'unroot' the phone, and this resulted in the phone proceeding to factory reset the moment it booted and i lost all my data :silly: So if root causes issues just re install the 311 files again to remove it.
[Huawei P20 Pro Guides, News, & Discussion] mosaiques:
Thanks for the explanation. I am on 311 rooted... If you can call it "rooted", since this new EROFS file system we can't do much.
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
Has anyone used dload method? And is there any prerequisite here, eg do we need to boot to the earliest version of 9.1 first or any initial files as I can see a few on ff called 9.0-9.1 just can't be bothered rooting my handset for the upgrade but I'm impatient [emoji23]
[Huawei P20 Pro Guides, News, & Discussion] sniper20:
The only pre requisite is to have a Dload otg file firmware. Have you found such file? In androidhost.ru haven't found yet.
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
No haven't had a look yet though tbh I haven't had to look at that for a while since rebranded so forgotten what I'm looking for [emoji23] isn't it just one with two file/folders, update file and firmware file?
[Huawei P20 Pro Guides, News, & Discussion] sniper20:
Yeap that's the one. Till now in androidhost.ru there isn't one for the 9.1 version. If you something that i have missed please write here. Thanks in advance.
[Huawei P20 Pro Guides, News, & Discussion] kaiowas82:
extract the ramdisk from. 311 and use magisk to patch it and fastboot to flash it, then factory reset from erecovery...all good here and haven't lost any data or functionality,the phone started just like before

It looks like an old tutorial with updated firmware version. Ff package will never work with dload otg version. It's useless.

We need androidhost package.
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
You CAN get otg versions off ff. When you click the version select the download button and it will show the files that version contains. Just have to find one that is service firmware
[Huawei P20 Pro Guides, News, & Discussion] forever_lol:
I know how to download packages from firmware finder. The thing is they will never work for otg download., simply because the structure of packages is not entirely the same as those you can get from androidhost. Many of us have tried.

Which are the correct files?? Have you tried it yourself??

On the B311 Build C431 is the contact and phone app not working with root. Without root is working perfectly. :/
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
You misunderstand I'm not staying for 9.1 specifically I'm talking in general..... Ff points to all released versions including service. But no as yet none of them look like correct ones for us non-rooters
[Huawei P20 Pro Guides, News, & Discussion] bravo261:
yup, a few of us here have that problem. i can't even downgrade, so i'm stuck with non-root and its killing me
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
Annoyingly it seems the C782 version that has appeared on firmware finder rmay be service firmware. Typical.

Did anyone tried flashing C431 9.1 Rom on C636? Wonder if it works
[Huawei P20 Pro Guides, News, & Discussion] Pretoriano80:
The question about that C431 version (even if it works on other cust) is if people will be able to update/downgrade from that! xD
[Huawei P20 Pro Guides, News, & Discussion] Macmoc16:
I can update via hisuite. I registered the c431 version via firmware finder. At the opening of hisuite he tells me the update as it was for c781 (my current model). Can I try to upgrade? Even if the firmware is not marked as approved?
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
No, 782/781 and 432/431 are different regions and it will likely failed to verify update even if you get it to start. Or worse..... Brick the device

There is a C782 version on firmware finder if you want to try, try that one
[Huawei P20 Pro Guides, News, & Discussion] KennyDumah:
Did anybody actually manage to downgrade from 311 yet?
[Huawei P20 Pro Guides, News, & Discussion] Macmoc16:
The 290 version has been released on firmware finder, I think for the rollut? So shortly also 9.1 in the global version?
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
Almost just rooted my .286 to get 9.1...... But can't bring myself to do it [emoji23] hauwei need to haul ass or someone find a dload version.

Really confused that there hasn't been any updated versions on ahost for a month now when I search. No NEW ones anyway. All just 9.0
[Huawei P20 Pro Guides, News, & Discussion] silverstream:
CLT-LGRP2-OVS 9.1.0. 320 released. This seems like the earlier universal version.

Had anyome tried it? Wonder if it'll work on my C636.
[Huawei P20 Pro Guides, News, & Discussion] Macmoc16:
Is the firmware approved for you?
[Huawei P20 Pro Guides, News, & Discussion] silverstream:
Not approved, however all earlier versions of CLT-LGRP2-OVS were not approved when I installed them
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
How are you planning to install? Dns etc from ff don't work now. Lgrp2 in theory are all other regions than China BUT firmware seems to also be being released back on region codes eg 431 aswell
[Huawei P20 Pro Guides, News, & Discussion] silverstream:
Planning to use EmuiFlasher
[Huawei P20 Pro Guides, News, & Discussion] Macmoc16:

[Huawei P20 Pro Guides, News, & Discussion] matt4321:
Did it give an error at all?

Interested to know how we're going to get to install EMUI 9.1 on our devices.

Weird as people managed to install .311 which is EMUI 9.1
[Huawei P20 Pro Guides, News, & Discussion] Pretoriano80:
That B311 is different from what i saw on other firmwares,it has 2 files.

With Mate 10 Pro for example, all 9.1 firmwares from FF are failing to install (error at 62%),but those firmwares come with only one file.

Probably those firmwares also require CUST and PRELOAD, which might be included o in B311 , instead.
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
Ah yeah, just had a look in FF and see the 2 files in .311 and .320 just has the regular update_full_base.zip. So other Huawei devices are failing to install 9.1 too then due to the lack of a second file with come cust stuff?
[Huawei P20 Pro Guides, News, & Discussion] Pretoriano80:
Yeah, at least that's what recovery.log says! But only Huawei knows for certain, of course!

P. S. Those with 311 already may succed to install B320, but hey, it's Huawei that we talk about here! ?
[Huawei P20 Pro Guides, News, & Discussion] josdehaes:
Not yet able to recover the device. Was able to boot into Phh GSI once, but now it always bootloops to bootloader. Can get it into TWRP every now and then (via erecovery), but always goes to bootloader. Ercovery also doesn't work, says can't get package info or something.

Tried with putting recovery commands in /cache and flashing nocheck recovery from TWRP, but once it boots to nocheck, it doesn't install the update (tried to go back to 295), but just presents the normal stock recovery screen.

Any help GREATLY appreciated ;)

update: can not get it into recovery in any other way than via erecovery (always tries to boot to system). Anybody knows a trick for that?
[Huawei P20 Pro Guides, News, & Discussion] Pretoriano80:
Hit me on Telegram, i'm [MENTION=2642882]Pretoriano80[/MENTION] there too. I will try to help you sort this out.

[Huawei P20 Pro Guides, News, & Discussion] djlukas1983:

320 success

Hello,

I've flash 9.01.320 with success on 9.01.311 with EMUIflasher 1.1.

I've rooted with magisk 19.4.736729f5 and magisk manager 7.3.3-f1112fdf.

I repack twice RECOVERY_RAMDIS.img (don't get root first time) and flash recovery with Multi-Tool 8.0.8.3

Need to boot in recovery with multi-tool first time.

[Huawei P20 Pro Guides, News, & Discussion] bravo261:
i flashed from C431 311 and am still C431 on 320. gonna try again to root it without breaking phone/messages

Update:

I got my dialer and messages working by flashing 311/320 and then flashing a non-patched ramdis. I booted the system and then did a factory reset in erecovery. as soon as the reset is done, i did NOT let it reboot and held the power button to power it off. I then flashed the patched image and then booted into rooted 320 with working dialer and messages again, finally. previously, third-party dialer/sms apps also didn't work as a workaround either
[Huawei P20 Pro Guides, News, & Discussion] djlukas1983:
Unfortunately it's C431 maybe because my previous FW was based on C431 too.
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
OK, what is the proper way to root on pie as seen a few comments saying use specific twrp and magisk, don't patch own image, use a pre-downloaded patched ramdisk image etc? I'm getting bored and wanna play with my phone. Any suitable versions and links appreciated [emoji106] including source for 9.1 if ff version is no good. I'm on C432 9.0.0.286 atm
[Huawei P20 Pro Guides, News, & Discussion] djlukas1983:
I've patched a recovery_ramdis.img like it was on EMUI 9.0 and just installed it as on 9.0. Nothing fancy here. To get root working I need to use pc and type command ADB reboot recovery because booting with a volume up pressed get you to an erecovery.
[Huawei P20 Pro Guides, News, & Discussion] blufreak:
Sorry to clarify, I don't care about root on 9.1 but need root on 9.0 in order to install 9.1 once 9.1 installs ill happily leave it stock. So it's just which versions of what should be used, 3rd party or official twrp etc

At first went directly from 9.0.250 to 320 >> failed, tried various ways to flash the update.zip with no luck.

Then, used the 311's two zip files mentioned earlier to upgrade to 311, then directly falshed 320, everything worked well (Didnt lose any data)

Flashed patched ramdisk before the first boot (extracted it from the 320 and patched it using the canary build)

Now debloated, rooted, Banking apps works as well as Phone and messages apps work.

The only thing so far is the Audio, I think its mono not stereo but not sure! will keep testing.

C782 is UK version, not Europe. You have a UK version phone and to date they have been very far behind on updates though based on firmware currently showing as pending that may be changing slowly

There is a thread specifically discussing C782 on here but you'll find minimal help without the likes of rooting or reasonable technical understanding of computer use eg changing dns and recovery procedures incase it goes wrong.

Flashed stock recovery_ramdisk and messages app start working and I recovered all my messages.

Flash again recovery patch by magisk and messages app still working.

This time to boot into bootloader and boot into recovery I used a different process, no adb commands were needed just power offf the device and waiting a few seconds then to boot into recovery/bootloader I used same process as old days.

Edit, it works only a few minutes then the issue return :(

OK unusual one here, flashed to .311 fine it came up saying user data locked requires pin after restart but wasn't asking for pin so I re did my pin, that's that sorted apps etc OK however when I lock and unlocky phone it just let's me open it by sliding the screen up. If I try set a fingerprint it asks for pin twice and goes back to same screen? Any suggestions?

** to add to this if I restart, it doesn't ask for pin but says pin required user data locked at top of screen and only allows me to access apps when I redo a pin code which it doesn't save anyway.....

I didn't finished the tests but so far msg app is working, I flashed the recovery B311 patched by magisk instead of B320, I didn't know if it makes difference but after flash I boot into eRecovery than power off the device (last option) than Power on + Vol+ and then the regular boot magisk.

Over here in the Great White North of Canada eh? I have found it's usually three to four weeks from the date it shows up on FF until it's approved. So I expect to see it in another week or two.

Oddly enough I see they released another .161 and .160 today. Seems very strange - three 8.1 firmware releases in the last four days. I know some people have been having huge issues with rollbacks, wonder if that's what this is all about...?
