If you find a 9.0 firmware in xperifirm, you can flash it with newflasher.
Both have XDA threads.

Already downgrade

This phone wasn't launched with lollipop, marshmallow, nougat so there is no such firmware for it. As for oreo, you can find all official firmware here.

You can try the tutorial given in this link https://forum.xda-developers.com/9-lite/how-to/unlock-bootloader-code-t3859685. I have not tried it as I've got my bootloader unlocking code from huawei, also you can get older firmwares for indian version from androidhost.ru by searching the correct model number. The link for the same is also shared in that tutorial by hackintosh5.

I can confirm that this worked on my device LLD-L31 (C432). Bootloader unlocked can install twrp flashes well. I have problems as a result of flashing xposed for the wrong version though so just be careful as my magisk flash now bootloops. I can't seem to find it but there's a telegram on xda somewhere where you can get help and that's where I got my slock when unlocking bootloader

If you have upgrade your bootloader and modem then you can not down grade to 8.
You can downgrade only by flashing custom oreo rom in twrp, there is no other way.

Hi m8,
Short answer is NO, because it might get softbricked and you don't have a doco dload firmware to use in order to downgrade to previous firmware on your device.
Flashing another device cust firmware was working well whille on EMUI 9.1 and users could flash the international dload firmware version (VOG-L29 C432 one) without the risk of getting softbricked. Once EMUI 10 was released, a lot of users got their devices softbricked, because of security changes inside kernel and within system itself. Some of them managed to revived their units using different methods or when Huawei released the firmware for their devices, but there are still many of those who are waiting for an dload firmware release for their custs.
So my advice is to wait for docomo to release the update and don't flash VOG-L29 C432 dload firmware on your device (or you could do it knowing the risks and assuming them). Untill today, no user from docomo tested if flashing C432 will work, because of the chances of getting a softbrick.

Hi m8,
I will answer for both posts :
1. YES, you can remove them using ADB commands. For how to remove, check my thread from here - https://forum.xda-developers.com/hu...w-to-remove-huawei-bloatware-vog-ele-t4014937
For finding out the name of the app you need to remove from your phone, install this app and use the original name of the apk's you need to remove (select app and press details) - https://www.apkmirror.com/apk/jumobile/system-app-remover-root/system-app-remover-root-7-1-release/
2. When you say you have the original firmware from docomo, what do you mean by that? Is it the dload firmware that can be flashed using an OTG adapter+memory stick (or Huawei NMCard) or some other firmware? As my knowledge, if you flash an EMUI 10 firmware and got softbricked device, YOU won't be able to downgrade to EMUI 9.1, just using a proper dload firmware (in your case the one released by docomo) could revive your phone. So in your case, i would wait for them to release the update ?
Let me know how can i help you more and be safe

For the dialer you can use the default Google Phone app and Google Contacts, maybe there are closer than what you're used to ?.
NO, you cant modify the firmware prior flashing it. If you / all of us could unlock bootloader and rooted our devices + installed TWRP on our Huawei phones, you could have flashed a custom ROM or remove/adding using ROOT ANY apps you would like. But as we can't unlock our bootloaders anymore, we have to use EMUI as is, customised by docomo or other provider. Only way to have a clean firmware is by getting an international or Chinese version of the device, one with C431 / C432 or AL-00 cust .
Installing other firmware COULD get you a softbricked device. I say could because nobody has yet tested flashing an C432/C431 cust firmware on the Japanese DoCoMo phones .

If your device is a P30 Pro Single SIM HW-02L (VOG-L0J) with Build ID : VOG-L0J 9.1.0.136(C341E136R1P2), then this firmaware is your original one https://easy-firmware.com/index.php?a=downloads&b=tags&tag=Huawei+VOG-L0J
Pay attention that in order to download that firmware you will need a paid account on their site

Ouch, i've replied you earlier about your firmware in case of backup, but it seems that you have a higher release version than the one available on easy-firmware.com (they have VOGUE-L0JB 9.1.0.136(C341E136R1P2) whille you have on your device v9.1.0.182(C341E136R1P2). So in case of flashing a C432 firmware on your device and get a softbrick, you are unable to return to latest available for your device. And as i've seen in your SS, there might be some problems regardless LTE basebands, which may be different in Japanese device vs European (International version).
So i would reccomend you to wait, maybe your next 1-2 firmware updates will bring you EMUI 10, alongside March/April security patches, as now you have January 1st 2020 on it ?

Hi there, m8. If you would asked me before?, i would recomend you to stay on your actual version... But now it's too late, so you will have to try using the GMS methods to install & use Google Services on your device.
I would also reccomend you to use a dload firmware to get back to your original cust, but there's no EMUI 10 n'or EMUI 10.1 dload firmware released for VOG-L0J .
For info about how to install GMS, use YouTube or xda P40 Pro thread:
1. YouTube - link 1 / link 2 or just search for How to install GMS on Huawei P40 Pro
2. P40 Pro xda thread - https://forum.xda-developers.com/hu...uide-method-to-install-google-mobile-t4120143 or https://forum.xda-developers.com/huawei-p40-pro/help/gms-method-t4163345

If you have an dload firmware for EMUI 9.1 and you will flash it, there's a BIG problem: YOU WILL GET YOURSELF A SOFTBRICKED DEVICE! The only way for you to rollback to EMUI 10 and then to EMUI 9.1 is through HiSuite and by using the right firmware for your device. I know that there's none released, so unless you get yourself (maybe from a Phone Service Center) a dload firmware EMUI 10 or EMUI 10.1 for VOG-L0J to use it, then you'll need to use your device AS IS ?.
Hope you haven't used the EMUI 9.1 firmware untill now and you get to read this before

Impossible to flash roms on P30 pro

Hello,
I brought a new P30 pro VOG-L29C, i found it with 9.1.0.260(WEC891E3R1P5) so i tried to update form Hicare and Hisuite but they say i have the last version.
So i downloaded Roms :
* Huawei P30 Pro VOG-L29 hw eea HLRCF VOGUE-L29C 10.0.0.190(C431E19R2P5)
* HUAWEI P30 PRO VOG-L29 HW EU VOGUE-L29C 10.0.0.168(C432E19R2P5)
But when i reboot to flash it with usb it says : incompatible version
Can anyone help me to update to VOGUE-L29C 10.1.0.123(C431E19R2P5patch02) ?
Bad ROMs, You must flash C891 as You got in default. Search in Firmware Finder which version is for Your phone.
BTW You have demo version

NO one can help you, m8! Search @ this forum and see how users got softbricked demo units for the last year!
There's no dload firmware for DEMO units since EMUI 9.1. ON EMUI 9.1 demo units users flashed VOG-L29 C431 dload firmware and that's how they update device. On EMUI 10 things got different when updating and everytime you choose to update with various dload firmwares or methods, you end up with a softbricked device.

Huawei isn't supporting anymore those devices because they are not sold as retail one, those are intended to be displayed on retail stores, for demo.

You would need an unlocked bootloader ? for that (which isn't possible because Huawei isn't giving them anymore) & it would require a rebrand to your phone. But without unlock bootloader code there is no root, no rebrand....
If you will flash & succseed any dload firmware for C431 you will get softbricked & untill now, there's no way to revive device.
My advice is to use it as is, with EMUI 9.1 on-board. Or sell it and buy a retail unit, that's way better than having a brick - in case you still go & flash EMUI 10/EMUI 10.1 on it -or staying on EMUI 9.1 ?
