This manual update doesn't require root.

It requires TWRP recovery only. Root can come after, if you want.

That requires unlocked bootloader but you can relock later, system will stay the same I suppose, only with recovery changed will be different from an original firmware.

Will unlocking of my bootloader cause my phone to factory reset?

I have the same device (L09C432) but I think my phone is branded, can I safely update my device manually with the exact same firmware as CaptainKaracho used?

Here are my firmware details: https://i.imgur.com/3HefrgK.png
[Huawei P20 Pro Guides, News, & Discussion] CaptainKaracho:
My Device was/is also branded by Vodafone (see pic).

BTW: Really don't know if this is an important detail for flash-process, but my device is VDF-branded & NO SIM-Lock were installed.

After I did the manual update I am getting a build number of "Chipset-Boston" etc.

I rebranded my L09 into L29 but I updated with the L09 version of "update_full_CLT-L29_hw_spcseas.zip" though

EDIT: Fixed it. Make sure you follow what you had initially rebranded to

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

Still working.

same here, huwaei firmware finder didn't download the files on the phone so i move to the PC version, could you please confirm these are the right files for the 152 ?
[Huawei P20 Pro Guides, News, & Discussion] ante0:
If you want it to replace eRecovery you can edit the flashRecovery() function in update-binary in the HuRUpdater zip.

However, if things go wrong you won't be able to get to eRecovery as it's not flashable from fastboot.

To enter, you can use Vol Up + usb or hold volume up for 3 seconds (Or until you see it booting to recovery) on the "You phone is unlocked" screen.
[Huawei P20 Pro Guides, News, & Discussion] med.bassia:
after waiting to download 4gb with eRecovery, it said recovery failed .. any suggestion CaptainKaracho ?
[Huawei P20 Pro Guides, News, & Discussion] CaptainKaracho:
I can't confirm, because

1. I flashed .152 firmware for a different device-version. (CLT-L09C432)

2. '152' is just one of 4 aspects, how to choose right Firmware for right device ;)

Only thing different from what i see is that you are using HuRUpdater 0.4

am using 0.3

I dont know if that make any different in result,

Updated version was meant to be better in most cases, but in certain case it introduce bugs as well,

You might want to try using 0.3 version probably,

Who knows, you might have better luck

Careful when updating further than .152

This ****ty huawei released kernel patch on OTA for several models that make it impossible (at least for now) to flash or use magisk. Means no root. Topjohnwu confirmed this on his twitter.

So, if you need root, stay on .152 for now. Until further details is available.

This applies for OTA and for manual upgrades too? I'm thinking of returning the device and have back my money

You can do it, but keep in mind that could be something not ready yet. It is usually safe for everyday usage.

For example, some time ago I installed a not approved firmware and playstore was not certified, until I installed the verified version.

How do I know if the firmware in the firmware finder is the proper region?

It's not confirmed through imei, but I would like to flash it. I have a CLT-L29(C432) European P20 Pro dual-sim.

The firmware I would like to flash is 8..1.0.159 (I'm on 8.1.0.156(C432) now).

How do I know which one of those two FullOTA updates I can use for my EU model?

I downloaded one of them, the filename is "update_full_CLT-L29_hw_eu.zip". Does the "_eu" in the filename means that it's the update for an EU device? Anything else I need to know?
[Huawei P20 Pro Guides, News, & Discussion] otonieru:

[Xperia Tablet Z Q&A, Help & Troubleshooting] bjoeg:
So mom dropped off her old Xperia Tablet Z SGP311 as a "gift". It did not work for her anymore, so if I wanted it and could fix it then I would have another tablet in the pile.

Her description of what did not work was what you would expect from a non-techie aka "some error turned up but I cannot remember what the screen said, so can you fix it?".

In the beginning I thought the problem was the common USB/charging problem, however I feel anything about this tablet seems different than other Android tablets, so after finally managing how volume buttons along with power buttons work, I could rule out it was a charging issue.

Getting the Tablet to boot it seemed that it had been updated and was booting into OS doing the "optimising applications 1 out of 258". However going to the step "starting applications", then tablet would just reboot a few times and then start over with optimising applications, starting applications, reboot and repeat all over. So some sort of bootloop.

I then used Sony's Xperia Companion to repair the tablet from fastboot (volume up + power) which succeded until it should reboot the tablet, then I was stuck in the same loop as above.

After a few tries I then managed to unlock bootloader and get TWRP 3.2.2 booted onto the tablet (booted NOT installed since I have no root).

With TWRP I tried deleting Dalvik cache etc., which did not help the situation, same bootloop.

With TWRP I then gave LineageOS a shot, but LineageOS experience kinda the same bootloop (both LineageOS 14.1 and 15.1).

LineageOS boots fine and proceeds with the fresh install questions (region, timezone, Internet access) but as soon as I hit next on the "Location Services" page the tablet will reboot.

Since this tablet has no value to me, I have tried deleting all data on all partitions from TWRP, I have checked the filesystem with e2fsck on the tablet which shows no errors, but in any attempts it simply reboots at the same stage every time.

So are we at the level where this might be some internal hardware failure (GPS/WiFi chip, NVRAM)? Or is there any suggestions of what else to try other than throwing this to recycle bin.

Hey guys, I recently updated my Moto Z Play, retin version to Oreo...Rooted it via magisk and installed xposed.. So far everything seems good and the battery has also improved a lot.. The only thing that bugs me right now is that i am unable to modify /system files... I was trying to change my bootanimation.zip file...Used RootExplorer, FX Explorer, Root Browser but to no avail..All of them were denied RW permission... Tried booting into TWRP and mounting system as RW, moved the bootanimation.zip to system/media and as soon as i rebooted my device, the change was reverted... It seems any change we make to /system is reverted back due to verification at boot... Is there a way to enable RW access so that i can modify /system files... Thanks :)

Try looking for a system_root folder that Magisk creates and see if you can change it there.

[Moto Z Play Questions & Answers] tag68:
My problem is the opposite: it is way too easy to mount system rw. One click ona button in TC, and I won't be able to do OTA without flashing system again.

So, I don't want to find out if system is mounting rw on my mobile. These modifications you want to do are better to do in Magisk way. If you do a system update, you keep your Magisk settings, so modifications will stay. OTA will only require uninstall of Magisk. Why do you want to do them the hard, incompatible way?

[Moto Z Play Questions & Answers] Artim_96:
TWRP can do these changes when you disable the "mount system as RO" in mount settings. But you'll have to flash a zip that removes dm-verity too, otherwise it won't boot up. Magisk will most likely fail to change the bootanimation on many devices because it can't replace it soon enough.
