[Huawei Mate 20 Pro Questions & Answers] Limeybastard:
Was your emui last update ota? What version were you on before 10? And how was it installed.?
[Huawei Mate 20 Pro Questions & Answers] steveli92:
Can someone confirm that once EMUI 10 is officially released in your region, the soft brick will be resolved?
[Huawei Mate 20 Pro Questions & Answers] hsarao:
Yes it was OTA update. I do not remember the minor version but it was 9.1.x.xxx. I just received update notification and it installed on its own. I did not use any external tools.

I tried recovery with hisuite and erecovery but every thing fails.

Are you guys sure that soft brick will resolve after they release it for phone's region. The phone model is Mate 20 X and I live in the UK.
[Huawei Mate 20 Pro Questions & Answers] m00mi:
Most probably the available update is for ONLY LYA L29... Not for LYA L09.. Nowhere EMUI is seen for LAY L09.
[Huawei Mate 20 Pro Questions & Answers] Limeybastard:
Go read the p30 pro forums. Apparently dload method can work for softbricked devices. Using correct firmware and OTG .
[Huawei Mate 20 Pro Questions & Answers] bondaru18:
Yes, this update it's only for LYA-L29 not for LYA-L09. So, don't put this firmware on yours LYA-L09. I repeat ONLY FOR LYA-L29
[Huawei Mate 20 Pro Questions & Answers] eduardoi7:
Anyone got any solution for this brick?
[Huawei Mate 20 Pro Questions & Answers] james1123:
I have my device up and running again now by dload method! (LYA-L09 C432)

This is the firmware i used: Laya-L29C 10.0.0.154(C432E7R1P5)_Firmware_NA_EMUI10.0.0_05015KSC

In the DLOAD folder you will have:

- update_sd_cust_LYA-L29_hw_eu

- update_sd_preload_LYA-L29_hw_eu_R1

Replace L29 with L09 then flash the firmware twice with dload, factory reset and wipe cache.

Dont know why i had to rename them but that was it! :)

Massive thanks to Oslo83 for his help, wouldnt have got there without it!
[Huawei Mate 20 Pro Questions & Answers] Monk3y:
How did you flash twice? Because it reboot the phone automatically
[Huawei Mate 20 Pro Questions & Answers] james1123:
When it reboots i held the power + up key again to go back in to the update screen
[Huawei Mate 20 Pro Questions & Answers] Monk3y:
Alright great! I am still scared to brick my device :rolleyes:
[Huawei Mate 20 Pro Questions & Answers] james1123:
Yeah... I rushed into it and mine was bricked so if you have a working device i would just wait it out to be honest :)

If your phone is bricked then its a way to get it working again
[Huawei Mate 20 Pro Questions & Answers] Monk3y:
So you brick your phone and then did rename the file with L09, dload it and you got back you device up and running?

If I understood it is a great news for people with bricked devices
[Huawei Mate 20 Pro Questions & Answers] james1123:
Yeah, so i flashed to EMUI 10 firmware which bricked my phone, couldn't restore or flash anything other than that firmware.

Then with help from Oslo83 we managed to unbrick it using the method i mentioned.

We need to do one more thing a bit later on regarding correcting the cust and preload to be LYA-L09 but at least people can get their phones up and running now :)
[Huawei Mate 20 Pro Questions & Answers] Monk3y:
Are you gonna modify the file to make it safe for install via dload?

Or only rename the file work?
[Huawei Mate 20 Pro Questions & Answers] phatwayne:
Unbricked!

Just reporting that I am now able to boot my phone. Kudos!
[Huawei Mate 20 Pro Questions & Answers] james1123:
Err not too sure, either that or some nice clear instructions on carrying out the operation

---------- Post added at 04:07 PM ---------- Previous post was at 04:06 PM ----------

Wicked! there will be another step regarding preload and cust to get the build numbers etc. right but at least you have a working device now :)
[Huawei Mate 20 Pro Questions & Answers] Monk3y:
Cool, I've got the file you use as well, will wait to see some feedback and dload it
[Huawei Mate 20 Pro Questions & Answers] dog121:
Am I reading this right just rename LYA-29 to LYA-L09 and flash all is good emui 10..
[Huawei Mate 20 Pro Questions & Answers] Monk3y:
Not sure at the moment...

Rename and flash it 2 times apparently work.... But wait and see
[Huawei Mate 20 Pro Questions & Answers] phatwayne:
Just clarify, I flashed with just the two files. The main update file had to be removed from my SD card, otherwise the update fails.
[Huawei Mate 20 Pro Questions & Answers] Monk3y:
The base update zip? How did it flash EMUI UI 10 without the base zip...

:confused: I am confused now
[Huawei Mate 20 Pro Questions & Answers] dog121:
The way I gather is just the preload and cust have to be renamed the base.zip stays the same

---------- Post added at 06:10 PM ---------- Previous post was at 06:09 PM ----------

The way I gather is just the preload and cust have to be renamed the base.zip stays the same as the base zip has no region
[Huawei Mate 20 Pro Questions & Answers] Monk3y:
Yep, that could be how they managed as said before :

-rename L09

-dload firmware

-Power +vol up when reboots

-wipe cache and data

-dload again

But we have to wait until the right method comes out
[Huawei Mate 20 Pro Questions & Answers] djpeesh:
Thank you! This worked brilliantly and my phone is back from being paper weight! Woohoo. Now the only problem is what do I do with this OnePlus 7T that I bought because I didn't have another phone and my job needs me to be connected 24x7.

Feel a bit idiotic.
[Huawei Mate 20 Pro Questions & Answers] dog121:
ok i took the plunge did the rename two zips put it on my usbc flash drive let it update no problems didnt need to flash twice ..just one install

now i have emui 10... before u do this do a backup on hisuite so u can restore afterwords ..
[Huawei Mate 20 Pro Questions & Answers] Monk3y:
OK so let's do that :silly:
[Huawei Mate 20 Pro Questions & Answers] dog121:
​

plus side i seem to have gotten rid of the EE bloatware normaly every update i do via dload i always get a EE settings update but not this time

so was kinda worried that i might have issues calls,texts,all working great..
[Huawei Mate 20 Pro Questions & Answers] Limeybastard:
Sell the mate 20.
[Huawei Mate 20 Pro Questions & Answers] Monk3y:
Done as well, really happy with EMUI 10 :fingers-crossed:
[Huawei Mate 20 Pro Questions & Answers] djpeesh:
Trying to give it to the missus but she's happy with her OnePlus 5T.

As a side note, I've realized that the camera on the OP is actually better than the Mate20Pro. Zoomed in, the OnePlus captures better detail and is less fuzzy. However, the night mode is superior on the Mate.

Also, the OP is blazing fast and refuses to stutter or pause for a breath. On the other hand, the Mate has a waay better battery life and better screen on time.

EDIT: did anyone else get a 7MB OTA update on the Mate 20 Pro (Says it makes UI improvements)
[Huawei Mate 20 Pro Questions & Answers] phatwayne:
I had already flashed the phone, resulting in the softbrick.

The get the phone to boot, I flashed only the two files.
[Huawei Mate 20 Pro Questions & Answers] oslo83:
That is just a temporary fix making you able to boot. You are with cust and preload from wrong model which breaks your build number, which breaks your safetynet.
[Huawei Mate 20 Pro Questions & Answers] dog121:
So theoretically when the LYA-L09 version of 10 comes available for Dload we should be able to rectify the cust,preload files ..
[Huawei Mate 20 Pro Questions & Answers] oslo83:
Yes.

In the meantime, I think we can force install right approved online emui10 cust&preload with hisuite and hisuite launcher.

[Huawei Mate 20 Pro Questions & Answers] hsarao:
Thanks for the info. Was anyone able to recover their data from the soft bricked device?

Waiting for the EMUI 10.0.0.180 dload build for C636 Mate 20 X to try this method.
[Huawei Mate 20 Pro Questions & Answers] dog121:
It will say LYA-29 software because this software isn't really ment for LYA-L09 but when the emui 10for LYA-L09 dload comes available u will be able to flash that ontop and bring Ur system back to its original version...

---------- Post added at 01:35 PM ---------- Previous post was at 01:24 PM ----------

Ok there seems to be a little confusion as to what u need to do to install this emui 10 LYA-29 software on an LYA-L09 phone...

Firstly download the software for LYA-29 emui 10

Then extract the zip . afterwards u wil have two folders inside the software folder u will find a dload folder with three zips two zips have LYA-29 name rename them to LYA-L09..

Then copy the whole dload folder with all three zips to USBC flash drive and flash the firmware if u don't know how there are threads all over XDA on how to..

Afterwards u will notice that the about phone settings that Ur device is LYA-L09 but the software version is for LYA-29 everything seems ok it passed safety net ect.. do not panic u will be able to resolve the software version when the new LYA-L09 firmware for Dload is available...

[Huawei Mate 20 Pro Questions & Answers] MeHMeTDaLGiC:
I understand you're using the wrong files. Search for "mate 20 pro" from the site "https://androidhost.ru/search.html". Download the appropriate file for the region code. Inside the file you downloaded

* - update_sd_cust_LYA-L29_hw_eu

- update_sd_preload_LYA-L29_hw_eu_R1 put the files in the DLOAD folder.
[Huawei Mate 20 Pro Questions & Answers] Darik.Harian:
Hi everyone!

For those that have failed in Latinoamerica region, rename too the two files, cust and preload from "eu" to "la", follow the same steps, dload + factory reset + wipe cache + dload again and voila! Mate 20 Pro Unbricked with Emui 10

After the soft bricked from the Emui 10 installed no Download mode

Since I soft bricked my phone by soft bricking it. I used to be able to enter the download mode to flash the dload file by pressing vol + and vol - and the power button.

Now since installing the EMUI update if I press this buttons then it goes into erecovery mode.

I am able to enter fastboot mode though but I doubt I can flash the EMUI 9.1 firmware in fastboot?

How do I enter into bootloader mode?

Thanks in advance
[Huawei Mate 20 Pro Questions & Answers] Monk3y:
No you can't you need hstool to do that but since you are soft brick it will not work.

Download EMUI 10 for LYA-29 (look on the forum the re is the link somewhere) then change the LY29 by L09 on cust and preload, dload it and you will be unbrick
[Huawei Mate 20 Pro Questions & Answers] Darik.Harian:
Hi, just press vol + (first) then power button and keep at the same time until you see the recovery menu

---------- Post added at 03:53 AM ---------- Previous post was at 03:20 AM ----------

I'm doing it like this, the installation process appears but it stays at 5% all the time until it restarts, is it normal?
[Huawei Mate 20 Pro Questions & Answers] Darik.Harian:
Ok, no.

Are three files: update_sd_base + cust + preload

Cust + Preload should be modified like this: L29 to L09 and EU to LA (Only for Latinoamerica devices)

All files inside dload folder, then you do the process exactly how was explained
[Huawei Mate 20 Pro Questions & Answers] cygnus56:
ok, I just did it twice just like that, but it doesn't work, change to "L09" and "la", what could be wrong?

My device is L09 (C69)

---------- Post added at 05:43 AM ---------- Previous post was at 05:33 AM ----------

the modification is only in the name right? Or do you have to modify any file within the zip?
[Huawei Mate 20 Pro Questions & Answers] Darik.Harian:
I see, my device is C605, I think your region is other.

Try this:

1.- Boot into recovery, just do factory reset and wipe cache and restart

2.- Follow the previous steps normally, keep "eu" don't change to "la"
[Huawei Mate 20 Pro Questions & Answers] cygnus56:
It doesn't work with "la" or "eu" :(

Desperate Mate 20 X owner

Helloo,

Can someone guide me through the steps needed to have my mate 20 x working again, and forgive my ignorance. When I say guide me I mean really really guide me:

- What version should I download for my global version mate 20 x (EVR-L29) ?

- Where from I can download it ?

- What is cust and preload ?

- I have a usb c flash memory and I have a huawei nano sd card, are these useful ?

I already bought oneplus 7T and I'm loving it but I think I prefer to be back to my X :crying:.

Huawei MAte 20 pro bricked after OTA update

Hello,

3 days ago I had an OTA update on the phone. Phone was charging, internet connection good, etc... and when it restarted it was unable to boot (Your device ha loaded a different operating system)

Read all the forums and my status is the following :

- Unable to boot in recovery mode (eRecovery)

- HiSuite stock update says phone is not compatible with recovery

- Unable to flash through dload folder on external card

I've created a FunkyHuawei account, connected with patched HiSuite, firmware downloads and extracts, but when it flashes recovery it reboots and goes to the same error display (it's supposed to restart in USB recovery mode, which looks like it's corrupted too on my phone).

I've tried with HsTool too and different stock firmwares, including the one detected on my phone (9.1.0.346 C432) and the same issue on flashing the recovery.

Please note that my bootloader and FRP are both locked. The only mode I can access is Fastboot, no ADB.

Help would be much appreciated because even if my phone is still under warranty, it was bought in a different country and Huawei doesn't have anything close to an international warranty. Local Huawei proposed to change the motherboard, but for 250€! Also, models available in my country aren't double sim but single sim, so I doubt they'll have the right motherboard.

Thank you!
[Huawei Mate 20 Pro Questions & Answers] oslo83:
Flashing (with dload) emui10 cust and preload package would help you to boot to normal mode.

It would be better you use emui10 dload packages made for your device model (L29) and region.

If not available yet, you can do a temporary fix with cust&preload dload packages from other model variant and/or region.

Just rename right the dload cust and preload dload packages for your device's variant and device's region.

[Huawei Mate 20 Pro Questions & Answers] Limeybastard:
Would you know the reasons why some people performing an official OTA get softbrick?
[Huawei Mate 20 Pro Questions & Answers] oslo83:
I would say it's because only base got updated to emui10, where emui10 checks at boot cust & preload version number if equal or superior to 10.

So, you ask why cust and preload were not updated to version 10 :

- Maybe base got updated cause you were on a base number your region device should have not been on.

- Maybe cust and preload were not updated cause they were not on latest version as they should have been for un-touched device
[Huawei Mate 20 Pro Questions & Answers] alutchmee:
Thanks for the update.

In my case, I never tried to crack the phone, or unlock the bootloader or anything. Just used it simply and updated when I was asked to.

The only thing is that I bought the phone in France and am currently in Mauritius where I launched the update that failed.

What's odd is that even the recovery modes aren't booting, so I figured I would be able to flash some packages in fastboot but as both FRP and bootloader are locked I can't do anything. I think I'll just have to call the warranty in France
[Huawei Mate 20 Pro Questions & Answers] oslo83:
On emui10, to access recovery menu:

1/Plug usb to PC

2/reboot device or force rebooting it by holding power button for 20 seconds or so until it reboot then release power button

3/hold volume UP button until you boot to Emui10 Erecovery

4/In Emui10 Erecovery, you'll find USBOTG option to use dload package.
