[HELP] Huawei Mate 20 Lite - Firmware/ROM Stock - Huawei Mate 20 Lite Questions & Answers

Hello friends, I need help to return to the factory system of my Huawei Mate 20 Lite (SNE-LX3) since the telephone company brings "by default" a ROM with its logo in the boot image and apparently blocks the possibility of using the Dual SIM. I was wondering if reinstalling the stock firmware it works normally.
My version of EMIU is 9.0.1 on Android 9
I hope you can help me.

Brand New Huawei stuck on erecovery screen

Hi,
I just switched from Apple to Android two days ago and don't know a whole lot about Android yet. I just got my brand new Huawei P20 Pro all set up yesterday and this morning when it went out of battery for the first time I naturally plugged it in to the charger. When I started it back up it went to the Huawei EMUI erecovery screen where it told me that something went wrong and I had a few options:
- Factory reset (recommended)
- Download new version and recovery
- Reboot
- Shutdown
I tried "Download new version and recovery" first and the package was successfully downloaded but when the phone had to restart it went back to the previously mentioned screen. I tried this a couple of times with the same result. After that I tried Reboot and Shutdown (trying to avoid having to factory reset) but it went back to the same screen again. Eventually I gave in and factory reset everything and it seems to have solved the issue but my phone still wants me to update EMUI and now I am afraid that it will do the exact same again. Does anyone in here know anything about this? Is it the new update or am I doing something wrong? How can I update without running into the same problem again?
My current EMUI version is 8.1.0
Thank you for your help.
8.1.0 is the latest emui, as far as I know. If it tries to update emui, you probably should do it because the Android 9 has already been released for P20 pro. If it's not Android and emui it is trying to update, probably it's a new build number. The latest is 156 c432 patch 03 with gpu turbo. Either way, you should update.

I tried to update it and it went through fine so it's all good now. I still don't know what happened the first time but I am hoping it won't happen again. Thank you for your reply.

Downgrade rollback emui 10 to 9.1

hi,
Ive joined here just to give some advice after trying for hours searching for a solution
The huawei hisuite stopped rollback to emui 9 in in one step, but if you roll back twice from 10.1 to 10 and then to 9.1 it works.
Hisuite version 10.0.0.510_ove , rolling back my p30 pro to 9.1.0.260 , hopefully have access to the phone recorder in built app too.
Don't know how to add an image of it though sorry.

If you're still facing the same error, post what version your phone on and what base, cust and preload versions you used.
Also what hisuite version you used to rollback and did you choose os type as Rollback Os in hisuite prixy?

P30 pro stuck on EMUI 10.1

Hello, XDAians
so I recently bought a P30 - used of course - downgraded it to 10.1
only loaded the wrong ROM, the phone was on C185 and I flashed a C431. Now of course I can't get any HOTA updates, the USB isn't working, so I can't use the HiSuite or the HiProxy, fastboot mode doesn't allow any modifications on android above 9, unlocks aren't possible with Kirin 980 devices, and whenever I try to flash the right firmware through e-recovery (C185) from professorjtj archives, the installation fails due to incompatibility with the current version (C431)
any Ideas on how to solve this ?
Thank you in advance

Emui 12

Hello,
I have upgraded my P20 pro succesfully to Emui 12 C432 via hisuite/hisuite proxy, my phone was on EMUI 10 before.
After the update, it's smoother, good battery life, but... My phone is not play protect certified. I think my phone was originaly C109 custom but on Emui there was no problem with C432 custom.
Now google pay and Netflix not working anymore.
Anyone have a solution?
Thanks.
