You would have to get the original firmware files and install in the same way but some have mentioned it may be problematic to downgrade, potentially bricking the device.

187 is valid firmware so why would you want to?
[Huawei Mate 20 Pro Questions & Answers] aygul12345:
I wondering if this OTG methode is possible with the Firmware release on this page;

https://xdaforums.com/mate-20-pro/how-to/guide-manual-updating-firmware-t3893171

On this page there is even .188 version out, So my question is 'Can you use also that firmware what higher is with this OTG methode?"

Or is this OTG methode an special unlocked Firmware needit?
[Huawei Mate 20 Pro Questions & Answers] steadly2004:
Only way to know for sure is to try it. ? Who'll be the tester?

hey guys, Ive got a Vodafone Aus mate20pro and after installing the above file gpay doesnt work and themes dont work. (as in i cant download a new theme, i click download but nothing happens). Not sure if my region has got something to do with gpay not working.
[Huawei Mate 20 Pro Questions & Answers] protuger:
Themes is working fine with me Optus Au Mate20Pro. Gpay and user icon in pull down menu are my only issues. I'm using Nova launcher so not really into themes. But hey this one looks cool.
[Huawei Mate 20 Pro Questions & Answers] rhath127:
That sucks for me lol. When I installed this firmware I had to manually install Huawei services from playstore. Did you have to do this?
[Huawei Mate 20 Pro Questions & Answers] protuger:
No. I have to restore from my backup in hisuite and that's it.
[Huawei Mate 20 Pro Questions & Answers] rhath127:
Update: to everyone who seems to be having issues with themes not downloading. I got mine to work...I uninstalled the update and the previous stock version seems to work flawlessly. I don't know if there is a way in playstore to block an update of a specific app but i hope this helps everyone.
[Huawei Mate 20 Pro Questions & Answers] Yuriksat:
Used Verbatim USB stick for that - the one having both USB-C and USB connectors.

Update went flawless, no OTG cabel needed.
[Huawei Mate 20 Pro Questions & Answers] srdempster:
Thanks to the op for this post, it's worked like a charm. I now have an international ROM and fully up to date. If I want I can now allow bootloader unlock just need to get the code to do this.
[Huawei Mate 20 Pro Questions & Answers] cygnus56:
did you uninstall it with adb?
[Huawei Mate 20 Pro Questions & Answers] rhath127:
Hi just with playstore , don't update the themes app.
[Huawei Mate 20 Pro Questions & Answers] kingbily:
First of all, charge the phone fully.

Next, enable USB Debugging on Huawei Mate 20 Pro by going to Setting>About>Software>Build Number and Tap on the build number repeatedly so that the Developer mode will turn on.

And then go back and click on Developer options.

In the developer options, there is OEM unlock option then enable that option.

UPDATE At the time of writing this article, Huawei has stopped allowing requests for unlocking the bootloader. But if the company allows the procedure in future here it is

Tech Droid Tips is not responsible if anything goes wrong with the device. Please do it at your own risk.

And now, firstly, login into your Huawei ID here, create one if you don’t have.

Thereafter go to > CODE REQUEST PAGE and login to your account.

And then agree or accept to the agreement page.

And now to apply for your Huawei Mate 20 Pro unlock code, fill in the necessary details ie, Product Model, Product Serial Number, Product IMEI or MEID, Product ID, and Verification code.
[Huawei Mate 20 Pro Questions & Answers] taniwhatuu:
Ok so... we have OEM unlock that can now be enabled.

And now I need the bootloader to be unlocked?

Does that mean I still can't install magisk and use it if I don't buy a code?

[Huawei Mate 20 Pro Questions & Answers] rhath127:
Hey guys, my phone was originally a c346xxx - i did the FH method global firmware and yesterday i reinstalled the firmware on page 1 as it indicates c432. However under build number its still the same and showing as a L29 variant but i have a L09 phone.

Please see attached pic

https://imgur.com/a/9RgW7PE

Im wondering if there is a way to erase the phone completely and reinstall the firmware from scratch.
[Huawei Mate 20 Pro Questions & Answers] charliebigpot:
Correct, you can only use magisk if you root and you can only root once you unlock the bootloader with an unlock code.
[Huawei Mate 20 Pro Questions & Answers] cygnus56:
Download the file for L09 and install as it says in the first post, it will work
[Huawei Mate 20 Pro Questions & Answers] rhath127:
That's what I did yesterday, exactly how it said. It didn't seem to change the build number.
[Huawei Mate 20 Pro Questions & Answers] cygnus56:
in the first post there are two files, the L09 and L29, you downloaded the one from L09 that is your variant?
[Huawei Mate 20 Pro Questions & Answers] rhath127:
Yes that's what I downloaded. I then extracted the files into the USB. Then connclectdd the USB via a OTG cable. Entered the #*# number and hit software upgrade. It went thru everything. However the only thing that remained constant from before and after was the L29 showing as the build number. I can't seem to force install the L09 preload and cust files
[Huawei Mate 20 Pro Questions & Answers] rhath127:
Update: so I tried it again, using the vol up vol down power method and somehow it updated . So now it shows as .187 c432. Thank you for all your help

Does this firmware support gpay?

Some users report what if gpay works, I can not prove it and what does not work in my country.

In the end how is the compilation? My device is C69 and the compilation appears incomplete, only C432E10 appears to me, and it should be like C432E10R1P16, does it come out complete?

Did you get the right download for your device (C432 v C636)

Perhaps try reformatting the memory card, what file system is it currently formatted as?

Yes c432 and i ve made it ntfs and fat32 same erorr.
[Huawei Mate 20 Pro Questions & Answers] W0rp:
On your flash drive there have to be only unziped dload folder. Nothing else. Also, if you researched this thread, you would read that not all OTG adapters work. For example, there are ones for a dollar, and ones for 10. Different quality I guess.

Ppl told us here that OTG adapter that came with Samsung Note 8 and work on that note phone, doesn't work on M20pro.

Just to be clear, your update proces reaches 100% and than tells you that update failed?
[Huawei Mate 20 Pro Questions & Answers] moshulika:
I have an otg 3 in 1 micro sd usb type c 8$ it finds my files, restarts, and when to start the update it says update fail please contact huawey.... Or the partition must be exfat?
[Huawei Mate 20 Pro Questions & Answers] W0rp:
After this manual 187 update and one day of use, I would like to report that face unlock is much faster, almost instant. Like less of a half a second. Camera images are a little more crispy, and finaly on Photo mode with front camera that stuped beauty mode is off. It's not 100% gone, but 80%. Wich is big improvement imo. I have more free RAM memory, and I think things are going a bit faster & better overall.

So far I charged the phone twice and it seems to me that battery life is little worse than it used to be. But I will give it a couple of days more to be sure of that.

I do not know about fingerprint scanner cos I don't use it. Face unlock is enough for me.

There are more small adjustments and changes here and there, about them some other time.

---------- Post added at 04:30 PM ---------- Previous post was at 04:16 PM ----------

It seems from here where I am (which is far away) that your phone do not want to be updated. Update version/files do not mach in some sense with the phone firmware. Either adapter is slow or unstable for phone to read files from it, or version itself is not suitable for your phone.

Where are you from anyway?

If you are able, try to find simple OTG female usb to usb-c. You said that yours is 3in1 something. The simpler device the better. I paid mine like 4 euros. It worked instantly. Try to buy one with the whole package/box, and not just plain adapter.

Also, double check and read carefully which version of this update you download, and what exact model is your phone.

Basically, double check all.

I do not think that partition must be exfat. I used brand new unused USB stick and it didn't need to be formated. Factory preferences were fine.

I can't help you much more from here. Good luck!

Hi, guys. I updated my phone with the usb otg method and it works. However my build number is not 187(C432E) but 187(C346E) instead. And I cannot use Gpay or nfc pay on other bank apps. I tried factory rest after update or someone posted vol up vol down power method but the problem is still there. Does anyone know how to fix this? Thanks.

C432 is the version you should have with the L09 i think. Check the first post with LYA-L09 version..
[Huawei Mate 20 Pro Questions & Answers] Firething:
please clearify what you mean .. it change your build to C432 from C346 right ? ... if so you need to do the same update again, but with the firmware that matches your region..

edit:: if you updated from .171 or newer, you might be able to use erecovery to get back latest region in your area ...
[Huawei Mate 20 Pro Questions & Answers] yellow122:

Response from Huawei

Thank you so much for using Huawei products and services. We totally understand how you feel that you would want the bootloader unlock code for your phone. Be rest assured we will assist you with our best efforts.

Pertaining to your inquiry, we would like to show our sincere apologies as there are no such options available currently to generate bootloader code. As this would impose severe risks to your device. Huawei used to provide users with corresponding unlock codes to meet personalized requirements due to the usage of different ROMs, which is an extra service and does not belong to consumer's rights. However, due to possible problems caused by such unlockings, such as system built-in function failure, device freezing, and power consumption increase, the unlock code application service has been terminated on July 25, 2018. This is for the benefit of users. Thus there is no available option to generate the code as the service is completely concluded. We are sorry again for such inconveniences caused.

Should you have further enquiries, please do not hesitate to contact us at 1300 482 934. Our technical support hotline operates from Mondays to Sundays from 9:00 am to 9:00 pm including public holidays.

Thank you for choosing Huawei and have a great day!

[MENTION=2742586]protuger[/MENTION] does Google Pay work?
[Huawei Mate 20 Pro Questions & Answers] miffymiffy:
Someone who may be able to assist. I see that upgrading is possible with International versions. Mine is a carrier version (optus) with C34 (not C43 which is common). I am wondering if anyone on optus has been able to do the upgrade, with or without B/L unlock.
[Huawei Mate 20 Pro Questions & Answers] Wearevoip:
It seems to me from my own experience and from these posts, that this update does not change the region. I already had C636 .187 and Google Pay does not work. I have heard The C432 .187 version does support Google pay, so I decided to do the upgrade. I did not get the option for USB, so I chose media card. Now it may be that my media card has C636 .187 in the media already (in an area I can't see), or it did in fact use my USB stick. Either way I still have C636 .187 and no Google Pay. :(. I have restored my phone from backup, but of course it still has a million wrong settings and lost passwords, so I have done a heap of work for nothing it seems.

If any one can confirm whether the region SHOULD change that would be great to know.

[Huawei Mate 20 Pro Questions & Answers] Wearevoip:
From what you originally posted, I would guess that you are still on C34 region code? Can you confirm this? If you are, it then confirms that upgrading to this firmware in this method (USB) updates the firmware itself, but not the region. I ended up on C636 by using the Funky Huawei upgrade. It works great other than with Google Pay. It is a definite improvement on an already fantastic handset. However, I think from what I am reading Google Safety net checks are done on a combination of firmware version and region code. Hence it doesn't work on C34 .187, or C636 .187, but apparently it does work on C432 .187.

I am sure there is a way to change the region code as I have done it by upgrading through the modified HiSuite and Funky Huawei. If we could get help with that, we could potentially both get our Google Pay back.
[Huawei Mate 20 Pro Questions & Answers] protuger:
[MENTION=3127296]Wearevoip[/MENTION]

I can confirm that I'm still on C34. Yes the firmware was updated but the region was intact. I'm still Optus branded and Google pay was broken because there is some mismatched files.
