Somehow can't find a firmware downgrade thingy for my device - General Questions and Answers

I got a KOB2-L09 Region C636 and I've been wanting to downgrade the firmware version but I somehow can't find any downloads for my device. Anyone know a great firmware database or something like that? I am unable to use a computer for the moment so I don't think I'd be able to use HiSuite Proxy.

You need a PC, otherwise, you can't flash anything even if you do find the firmware.

No OTA on stock

So I'm finally ready to say goodbye to my H8 but after relocking the bootloader ,rolling back and dloading B360 for the L09 i am unable to get OTAs.
I thought i could simply flash another version from FF but all that did is allow me to update through HiSuite.
Plus it (HiSuite) always says I'm on a developer version.
Could anyone guide me to a proper L09 stock version that i can dload or anything else that would help?
I think I've had the problem before but I can't remember what I did to fix it other than maybe downgrading to MM.
But dloading the same file after that seems kind of pointless.

I Had That Problem When I Rebranded.
All You Have To Do Is Use " Get An Update Through DNS" In Firmware Finder And Now I Had The Latest Version.
And Then While I Did That I Suddenly Started To Get Updates Without Firmware Finder
Oh And Also How To Get To Stock:

Well the issue is i did both of those and neither allowed me to get official OTAs.
I want to sell the device as long as its worth something so this is rather important for that
But the rollback files i used are quite old so maybe its a wrong version or something.
But I did update through the FF proxy, same thing.no luck
Edit: i did the proxy update so maybe thats the culprit, but isnt it just downloading the same version as the dns one?

Which fw you were trying to install. I do not understand how you can not install eg B380 because it is point version and approved install over dload. What about unlock bootloader and flash fw over twrp?

I can install it but not over official OTA.
Also i saw i asked the same question on your other thread and apparently downgrading to MM fixed it last time.
So sorry,i forget things easy
I will try that
Tried it again with the official Rollback package and MM firmware.
Got the OTA to B360 and now, no OTA again...
Anyone have any suggestions?

Firmware Finder in-app-proxy/DNS not working anymore - solution??

Hi,
I just realized that Firmware Finder can't update the device anymore as Huawei changed some protocol. That sucks as b370 was just approved for the Mate 9.
So how to upgrade the device now? Not interested in rooting and all the other junk that potentially brick the device.
Thanks
I not prepared to do this but someone on another thread said, you install HiSuite 8 onto your pc...connect your phone. Then you goto update firmware and it will say you have the latest version, which we know isn't true, but it will give you the option to downgrade to latest nougat..... This is true as it did give me this option...
Once downgraded, you can use your phone OTA to update back to latest oreo....... Phew!
Like I said, to much faffing around just to have latest firmware...

Downgraded base firmware now reboots every 20 seconds

I recently purchased a P40 Pro (ELS-N04 or ELS-lgrp4 base) which had .148 firmware on it. I used the firmware finder to find an approved firmware for my device: ELS-LGRP6-OVS 10.1.0.136 and performed the downgrade using the hisuite method. My device now reboots every 20 seconds and has no cellular connectivity. Can anyone point me in the right direction to correct this please?
I think if someone pointed me to the correct firmware, I could probably fix this through fastboot... Maybe?
Thank you.
Fastboot wont work unfortunatley. What you can do is go to androidhost.ru and find your firmware ( can be the same aswell ) Its roughly a 3 - 4 gb download.
1. Download the firmware of your choice from the link below:
https://androidhost.ru/
2. Put the ''dload'' folder found in the zip at the root of a usb stick
3. Attach the usb stick to you phone. I take it anyone knows how to do it. Shutdown your phone. Then press and hold volume up and power button until you get to the recovery menu
4. Select Update mode, then select Memory card/OTG update mode
5. The phone will verify and install the firmware
Make sure that your Emui 10.0.1.***(C********) Matches otherwise the update will fail.
Is there an easy way to identify the "correct" firmware? It looks like https://androidhost.ru/ only has one file available which isn't the same model version as mine.

Ok, I managed to downgrade to .131 after throwing caution to the wind lol.
Hello good someone from the forum can help me? I have a huawei p40 lite 5g firmware cdy-lgrp2-ovs 10.1.1.131 model cdy-nx9a, is there any firmware version to be able to install google services on is model? Thank you

Update issues after Downgrade

Hi all, I have downgraded my p40 pro to 131 to get google apps working. Then tried auto updates and it tells me that there is an update but same version 131, updated to 131 using auto update but it still keeps telling me that I'm on 131 and same version of update available. Connected to PC and use Hisuite and same story, tells me 131 update available (which I already have) and nothing else. Was able to update to 154 using proxy but now same story, it keeps telling me that 154 update available which I did auto update but I still get notification that I there is new update to 154. I cleared data and cache both for Huawei Core and Update app but still same story.
Please help!?!
You will need to use Hisuit Proxi & firmware finder to get more upto date firmware.

hi, should I update it using FullOTA-MF or OTA-MF only? thanks
Select Full, and use the check availability option to make sure its an approved for install as well, else it will fail.

thanks, another question is, will it wipe off the phone?
When I did mine, No. But remove or backup any personal stuff off your memory card if you have one, just in case. Note if you've done the GMS install, make sure you log into All you're accounts, ie YouTube etc first before upgrading firmware. Cause you won't be able to add later.

Update: Ok found it, it is via the advance button and paste the link there to check if it's approved or not.
Is this done via the HiSuit Proxy Advance button? how can i check if it's approved or not?
Use firmware finder to check it's an approved version.

Hmmm we are all on C636. No idea what went wrong. Only difference is 4RP1 and 5RP1. Any difference in those?
Same situation here, I downgrade to version 131 o install GSM and now the phone won't update.
I had to update it using HiSuite and now I'm on 183 version.
Hope there is a way to fix the OTA updates on the phone.
getting regular updates after installing GMS via googlefier
Doing some research I have found what is happening:
On your P40 Pro, in the "About phone" screen you can see the build number and then a number between ( ), example: Build number 10.1.0.131 (C636E8R5P1)
The number after the C will tell you the version or region of your firmware, in the example C636 = version/region 636
When you downgrade using a different version/region you will loose the OTA updates on the phone, and this will only be restored after you install your correct version/region firmware.
You will need to find the correct version of your firmware and have the "dload" version, and install it from external card. There is a video showing how to do this, but the link on the video is for a version/region 636, if you have a different version/region it won't fix anything.
Once you have the correct firmware and install it, you will begin receiving OTA again. This process, at least on my phone, erased everything, so be aware of this.

STUMPED on how to downgrade after GMS failure

Like to see if anyone may have a solution on how to downgrade back to EMUI 10 after a successful play store installation that eventually failed, I can not run any apps on the phone and can not upgrade. The p40 pro is an ELS-N04 C992 with EMUI 11.0.0.130.
I tried HiSuite with no luck, just the "no internet connection" and made sure the windows 10 firewall was open, it was. The firmware finder on my p40 is version 9.9.2 and most if not all the packages I check says the firmware was removed from the server!. I also tried to restore the phone from a few backups via USB but the phone does not recognize the files from the backup.
Ultimately what my goal is is to get back to the phone's original version of 10.1.0.183. Love some help on this and if someone has a solution man I would love to hear it!
Firmware finder project is closed I was told

Oh my god your kidding, so I'm stuck with a non-working p40 pro
If that's the case, (and I just read that) can you do an upgrade to a higher version or re-load googlefier to get it to work again?
Need usb adaptor. Download firmware for your device and region and downgrade via recovery options (hold power + volume up). Then use googlefier

download firmware you need off one of the many different firmware websites... might cost you 2usd or thereabouts. E.g. i found mine ELS-N29 10.1.0.114 (C636)... but thats for my specific model and region, so be careful to choose the right one or you could brick your phone
