Thanks for this method!! I was stuck on the "Your device has loaded a different operating system" on a VOG-L09 from New Zealand, previously had EMUI9 C636 and I was tried update to EMUI10 (using VOGUE-L09C 10.0.0.186(C431E19R2P5)_Firmware_EMUI10.0.0_05016TKC).

Couldn't find a proper C636 and gave it a go on C431, sadly got stuck on that error.

However, I did the file rename thing and it worked, got EMUI10 working. Thanks again!

Without knowing your actual build and cust, i can't help you.

In order to help you, i MUST know what your device CUST & build are.

Relax, take your time, then READ and do as following - https://www.hardreset.info/devices/huawei/huawei-p30-pro/faq/read-info-fastboot/

After you've done what it's on that link above, get this command:

fastboot oem get-build-number

Ok. Then Open Command Prompt from start menu with admin rights(if windows ask about rights just press YES).

If you do not change default folder ADB and FASTBOOT files are in C:\ADB

Now you need to go into this directory using the command:

Type cd\ and pres; enter key.

Type cd adb and press enter key.

Next use fastboot command:

fastboot devices and press enter button

This command checks communication with HUAWEI P30 Pro and confirms that all drivers are installed correctly.

fastboot oem get-product-model

and press enter button

This command read from phone product code / phone name

Those above are next steps after entering Fastboot and installing HardReset.info: ADB mini with Fastboot tools.

Hello fellows forumers,

IT IS WORKING, 100%.

After softbricked many months, and trying LITERALLY tens of firmwares and methods, this finally worked like a charm..

My phone was initially C432, but a demo version.

Removed by adb bloatware, and did several upgrades within the emui9 range, which ultimately changed my CUST to C636.

I did the normal OTG upgrades to EMUI10 from this forum, paying attention to CUST, without mistake, but ended up in a softbrick, of which I could not escape, regardless of what methods i used.

I flashed ALL firmwares.

I went to online assistance by phonegeeks around the globe through TeamViewer and dongle methods, without success.

UNTIL TODAY.

I prepared a firmware of my CHOOSE, which I liked, regardless of CUST.

I chose VOGUE-L29C 10.0.0.186(C431E19R2P5).

Flashed it OTG - NO SUCCES.

I prepared three USB disks, formatted exfat.

I prepared the firmware in the three folders, IDENTICAL, and then in forders 2 and 3 renamed the files as indicated in #SilviuO post.

Then copied each dload folder as such, 1 - original, 2- first rename 3-second rename,

I flashed them, in this order, with insucces between.

At the last flash - SUCCES - phone booted a new phone.

10.0.0.1.186D(C431E19), EMUI10.

REAINED DEMO but fully functional, without security measures.

Installed by adb fastboot passwerd, then firgerprint and face recognition worked.

Last night I ordered a MRT key dongle to hard unlock the phone, I will let you guyz know how it works.

Go for it, thanks Silviu.
[Huawei P30 Pro Guides, News, & Discussion] SilviuO:
Great info, m8. It's by far the best info for users who have a bricked demo device or want to update their ones to EMUI 10. Get your things done, then create a new one (or modify the actual post) with links and steps doing it so i add your breakthrough method on my OP. :cool:

Let us know if using that dongle get it like a retail unit:highfive:
[Huawei P30 Pro Guides, News, & Discussion] mihailuican:
It is not only working for demo versions, but for ALL BRICKED phones.

I am too old (almost 60) to write down tutorials and guides, I think the steps above in your original post and the link to your firmware plus my short explanation of renaming and using three usb disks to save time for renaming should be enough.

YOU should take credits, I just did one experiment on your instructions.

Bricked vog-l29

Colleagues, I have a little problem with a VOG-L29 C431. I downgraded it to 10.0.0.168 through OTG, from there with HiSuite to 9.1.0.161. It was fine so far, then I tried to downgrade it to .115 via OTG and somewhere after 70% it just went off and didn't want to turn on. Thanks.
[Huawei P30 Pro Guides, News, & Discussion] SilviuO:
Hi m8,

1. Why did you downgrade so more? It's not reccomended to downgrade so much, because of kernel modifications and different xloader and more security changes...

2. Did u try using latest EMUI 9.1 v9.1.0.260 dload firmware? Or using latest EMUI 10 v10.0.0.186 dload?

3. Is your device charging? When you connect to PC can you get to Fastboot? If yes, try using Fastboot commands so you know what version and build is on it atm https://xdaforums.com/showpost.php?p=81887785&postcount=418

4. If it's not charging/getting any info on Fastboot, i'm affraid that you might ''fried'' your motherboard and needs to be replaced on a Huawei Service Center...

[Huawei P30 Pro Guides, News, & Discussion] SilviuO:
If it's working and you can enter eRecovery to flash dload firmware, try first to flash an EMUI. 9.1 firmware (latest available for VOG-L29 C431 from this link ).

Before that, format your USB device as exFAT (or use another USB stick, maybe the one you're using got corrupted or something else), then copy the dload folder (with EMUI 9.1 v260 firmware) on USB device, connect it to your OTG adapter and press all 3 buttons simultaneously untill it starts flashing. Let it do the flashing. If still got errors, redownload the EMUI 10.0.0.186 again and try flashing (after formatted your USB device).

What are you calling '2- first rename 3-second rename' ?
[Huawei P30 Pro Guides, News, & Discussion] mihailuican:
First folder is normal dload orders (base, cust, preload)

In Second folder the files are named exactly as the original one, but order of files changed (preload, cust, base) - you swap names preload and base.

Third folder contains same file names as original files but renamed and reversed as follows (cust, base, preload) - you swap names between base and cust.

It takes a little logic - i made copies of both files to swap names - and renamed the originals. Don't mix up names, keep it simple.

The files are always named in the same order as the original, only the real files swap - that is first time they are normal order, second time first and last file swap position maintaining the naming, third time first and second file swap position but maintain naming).

First file is biggest, third is second and smaller, third is smallest.

SO, you get to flasht hree times with all the three files coming to first place named as base, while the first initial file, the largest, gets to take a third, then a second position.

Hope this is clearer now.

Good luck.

AND, if you rename the other two files update_sd_base.zip, they would flash as well.

---------- Post added at 09:49 PM ---------- Previous post was at 09:42 PM ----------

You're doing something wrong.

Every time of two rename stages, you have to rename two files, and switch their names, so that all three times you're flashing the same 3 file names, but with the switched content and sizes from the numeric model I've told you.

Do not know what else to suggest, redo the footsteps.

Success, now i have to sleep since exhausted.

HOW TO REVIVE softbricked & flash for C900 CUST + demo devices (bootloader depending)

In order to succeed, you will need to do as i wrote bellow! You can flash 3 times by replacing second and third time the dload folder from USB device or you can use 3 exFAT formatted USB devices, as you wish. Before proceeding, make sure that you have 3 dload folder with ONLY 3 zips inside (the ones extracted from my firmware, v186 for VOG-L29 C431 or VOG-L09 C431, depending on device).

FIRST folder to be used NEEDS NO MODIFICATIONS AT ALL, just do step 1 from bellow!

1. FIRST TIME FLASH the dload folder ORIGINAL, just as is from the extracted firmware - dload folder with all 3 zips files inside as following:

update_sd_base.zip (4207731 KB)

update_sd_cust_VOG-L29_hw_eea.zip (37 KB)

update_sd_preload_VOG-L29_hw_eea_R2.zip (206751 KB)

It will end up succesfully, but with softbrick.

SECOND dload folder do as step 2 bellow then flash it (copy the dload folder and replace the one used on step 1 if you are using the same USB device)

2. SECOND TIME RENAME update_sd_preload.zip TO update_sd_base.zip AND ORIGINAL update_sd_base.zip TO update_sd_preload.zip, resulting:

update_sd_base.zip (206751 KB)

update_sd_cust_VOG-L29_hw_eea.zip (37 KB)

update_sd_preload_VOG-L29_hw_eea_R2.zip (4207731 KB)

It will flash faster with flash successfully, still softbrick.

THIRD dload folder do as step 3 bellow then flash it (copy the dload folder and replace the one used on step 2 if you are using the same USB device)

3. THIRD TIME RENAME update_sd_cust_VOG-L29_hw_eea.zip TO update_sd_base.zip AND ORIGINAL update_sd_base.zip TO update_sd_cust_VOG-L29_hw_eea.zip, resulting:

update_sd_base.zip (37 KB)

update_sd_cust_VOG-L29_hw_eea.zip (4207731 KB)

update_sd_preload_VOG-L29_hw_eea_R2.zip (206751 KB)

Flashing will be instantaneous and will reboot and revive your device from softbrick.

Goodluck flashing and let me know if it worked :confused:

Hi. I have a softbricked P30 Pro demo unit with bootloader showing: VOG-L29 9.1.01.93D (C432E4R1P5).

Tried to update with dload name change but with particial sucess.

1 update (no change), sucess

2 update, firmware/software incompatibility

3 update, sucess

Tried already with some others fw but without any luck, 2 update always fails.

What fw should i use? Any advice on 2 update?

Thanks
[Huawei P30 Pro Guides, News, & Discussion] :
I can confirm SilviuO method that he gave me on telegram few days ago to revert to 9.1.0.260 (C431)

- First step: From EMUI 10 v186 downgrade to v178 using Dload method

- Second step: Install latest hisuite pc version. Connect cell with usb and check for new updates. From there you can select other version and then EMUI 9.

- Third step: launch upgrade (downgrade). It took about 15 - 20 minutes. Everything ok!

Advice: Before first step and after third step is good to erase data and wipe cache

For me EMUI 10 needs more developments and refinements. Poor notifications, consumption and battery management. Cannot stably connect my Garmin Forerunner 645 music.

So i preferred to revert to EMUI 9.

I'll test EMUI 10 in 3 or 4 months
