It's great to have this, but the big problem is... for that it need a unlock phone (bootloader and root)

my device is (C69), I updated by FunkyHuawei to the version .171 (C432E10) did not rebrand, the firmware I installed FunkyHuawei was (LYA-LGRP2-OVS 9.0.0.171), so now I want to install the firmware (LYA- LGRP2-OVS 9.0.0.183) available in this post, I made the folder HuaweiSystem and then in settings look for updates and I do not skip anything, is it possible to update my device in this way?

[Huawei Mate 20 Pro Guides, News, & Discussion] pvillasuso:
Thanks [MENTION=4960686]OldDroid[/MENTION]

Came from .182 and flashed the latest .188 with your app

Worked well for me , but I had to factory reset ( with the custom recovery ) at the end to make it boot .

Cheers
[Huawei Mate 20 Pro Guides, News, & Discussion] DN38416:
Yeah I think that's what happened with mine. It would only boot up with the patched recovery_ramdisk.img and not with a regular boot.

But I remember there were a few apps that seemed to have issues for some reason and I ended up screwing up everything by trying to do a factory reset in settings and then another in eRecovery.

Caused a soft brick. I ended up recovering the phone via FH method to 187.

But I noticed the FH firmware was different to my local one, so I ended up doing a firmware downgrade via eRecovery, which took me back to 168 (but with my local AUS firmware)

And a couple of days ago, it got an OTA update to 183. Which is where I currently am and staying, as it passes safetynet and Google Pay is working great.
[Huawei Mate 20 Pro Guides, News, & Discussion] cygnus56:
How did you do the downgrade via erecovery, what are the steps?
[Huawei Mate 20 Pro Guides, News, & Discussion] DN38416:
1. Go into eRecovery. (plug phone cable into charger or whatever, reboot and hold volume up until the eRecovery screen comes up)

2. Select Download latest version and recovery, then Download and recovery

However I've found that eRecovery often doesn't work for me. Ends up giving me a failed error when it says "Getting package info from server". Maybe being rooted or having a patched recovery_ramdisk.img has something to do with it.

Also, when I say "downgrade", just to be clear, it will only install the latest firmware that your Country or Carrier is releasing. I was on the stock 187 firmware by FH, when I ran the eRecovery, it downloaded the 168 firmware and restored to that.
[Huawei Mate 20 Pro Guides, News, & Discussion] cygnus56:
Do you know any way to update the firmwares of this post manually? No bootloader unlocked? I have installed the .171 (C432) of FH
[Huawei Mate 20 Pro Guides, News, & Discussion] DN38416:
No i don't, sorry. Not without the bootloader unlocked. I used the guide in auras76's thread https://xdaforums.com/mate-20-pro/how-to/update-unlocked-boolader-hwotamate20pro-t3886360 but needs unlocked bootloader unfortunately.

If it’s not, make sure Magisk manager is open in the background and open up emui flasher again. You should be prompted to grant root

Are you absolutely sure you booted to recovery? I was having the same issue, turns out I wasn't holding VolUp in long enough.

If I power on normally, I get the warning about my phone not being secure and a prompt to hold VolUp for 3 seconds to boot into erecovery. If I hold VolUp long enough, the warning is still there but there's no prompt for erecovery. Don't release VolUp until the Huawei logo is on the screen.

[Huawei Mate 20 Pro Guides, News, & Discussion] Minotaur:
In theory yes.

However in saying that, for some reason I don't need to any more. It just automatically boots to recovery, even if I just power on the phone.

It might have started doing that after I used the reboot tool in Root Essentials to "Reboot to Recovery" I'm not sure why to be honest

[Huawei Mate 20 Pro Guides, News, & Discussion] trainfire:
Everything is working perfectly! But after I turn off the phone I can't turn it on again using power and vol up. Just get into fastboot&rescue mode. The only way for me to boot is to hold power+volup+voldown and release power after I feel the vibrate. Then the phone tries to update software, which fails and then I press the shutdown button on the screen while holding volup. Then it boots up perfectly. It also works if I get to bootloader mode and use fastboot reboot command, unplug cable and hold vol up. Same thing I guess. Also, using apps to reboot the phone into recovery results in the same fastboot&rescue mode.

I'm still able to boot my phone so I'm happy. Just wanted to share the issue and temporary solution for anyone having the same problem, and maybe the is a real solution to this problem that someone can help me with.

Has anyone got a patched image for L0C models?

Even the L09 models version seems to be down.

Driving myself crazy trying to find this file.
[Huawei Mate 20 Pro Guides, News, & Discussion] mdrda:
I think it's thanks to some recent versions of Magisk which does reboot through recovery image during normal boot which supplements the manual VolUp boot method via boot.ing stored in recovery.

I came across an issue however. Thanks to this automagic stuff if something goes wrong with the boot image in recovery, then softbrick. One needs to flash a healthy recovery, e.g. the one in OldDroids OP. However that boot image is patched with older version of Magisk than current canary. If one has already some Magisk modules installed in the system, Magisk dies in a strange way. Magisk Manager reports there is no Magisk installed and Magisk Manager UI hangs on refresh. Also apps requiring root hang on calling SU. I've got no solution for this yet. I will wait for new ROM, load it via HSTool, which I assume will uninstall all traces of Magisk in the system and restart from scratch, hopefully with newer Magisk build. This one just does not play well with my LYA-L29. Or I screwed something :)

[Huawei Mate 20 Pro Guides, News, & Discussion] DN38416:

Yep. AFAIK, RECOVERY_RAMDIS.img hasn't altered in any firmware updates, so you should be able to use any.

Or if you're worried, you can just patch it yourself by flashing Magisk in TWRP
[Huawei Mate 20 Pro Guides, News, & Discussion] mdrda:
Had the same problem and few more, see few posts above. Resolved by flashing Magisk canary (v19.0-3eae9494 (19001)) patched TWRP recovery image for P20 Pro (Charlotte): https://dl.twrp.me/charlotte/twrp-3.2.3-4-charlotte.img.html

Patch that img in Magisk and flash it to recovery partition. All problems should be solved. Boot phone via recovery (VolUp+power) as usually to boot into Magiskified system. There will be no TWRP available, it just works the same way as the patched image in the OP, just takes a different path which worked better for me.

You mean I download that TWRP and patch to Magisk Canary than flash it as recovery M20P?

Step by step :

1. patch the recovery_ramdis.img with magisk canary

2. patch the TWRP P20 image with magisk canary

3. flash patched recovery_ramdisk (name output patched_boot.img) as recovery_ramdisk to M20P

4. flash patched TWRP P20 image as recovery to M20P

is that correct?
[Huawei Mate 20 Pro Guides, News, & Discussion] mdrda:
Yes that's what I mean. One update however, sometimes the device still failed to boot rooted (bootloop) and what has always helped was to boot via VolUp+VolDown+Power. It goes to EMUI recovery download screen which fails instantly and a reboot button appears. Tap reboot and hold VolUp during reboot till the "Booting system ..." appears. Then it boots correctly to rooted os. This has worked for me consistently so far though it's not comfortable. Hopefully new Magisk will fix this soon.
[Huawei Mate 20 Pro Guides, News, & Discussion] sunu792002:
- Patching TWRP P20 and flash it as recovery_ramdisk to M20P.... rebooting... failed to booting to system always boot to fastboot.

- Reboot again & holding VolUp + VolDown + Power, phone booting into recovery download screen and reboot button appear

- Tapping reboot and holding VolUp during reboot, it is reboot to system but still can not entering rooted OS, it's stop in loading screen (hang in last loading screen while entering system)

- Rebooting again without holding VolUp..... orange text screen info appear.... entering system with normal but not rooted

Well.... it's drive me crazy

I misread your post previously. Should make no difference but it was simpler

1. Patch TWRP P20Pro with Magisk Canary

2. Flash that patched TWRP into recovery of Mate20 pro via fastboot

3. Boot with VolUp+Power (in case of bootloop long press Power to poweroff and boot with VolUp+VolDn+Power, let it fail and then retry reboot with Volup)

Works for me, it's all I can say.
