Question: Safe to downgrade firmware ELS-N39 C636? - Huawei P40 Pro+ Guides, News, & Discussion

Hi, has anyone with ELS-N39 C636 managed to downgrade firmware successfully to prepare for sideload GMS?
The reason I'm asking is because my phone just got into a situation where it reboots every 20 secs. So, I've sent it to service center and they mentioned i will have to get motherboard replacement.
Few question from me
In what scenario will cause that to happen? Wrong firmware flashed?
Which way is more safe to downgrade? Hisuite proxy or OTG?
Seems like Hisuite don't check against current version?
OTG does check and will stop updating if some versions not matching?
I know i could have just flash back the correct firmware, but I've tried using Hisuite which wont happen due to constant rebooting. Also OTG mentioned my version don't match. So any better solution if this happens again? Any alternative firmware tools that is working?
I hope someone who knows the ins and outs of android could shed some light.
I've try to read up as much as I could but those mentioned are some concerns that I still have before retrying to downgrade again.
Thanks!

Here's my software version info

"Error: UEGetPhoneInfoFailure UE_2003" when trying to update to 6.0.1

Hi,
I just bought a sony xperia Z5compact from another guy that barely used it. He gave it to me with apparently, a stock ROM. But I dont know if the other guy did anything on the phone like rooting, unlocking, whatever.
But now I want to update from 6.0 to 6.0.1 and I cant do it. Neither in the phone, nor with the computer coz I get this error:
error: UEGetPhoneInfoFailure
UE_2003".
I checked more, and the phone has TWRP recovery and an Androdplus kernel. So it has been modified, but I dont know how to check the status of the bootloader or if it rooted.
I want to update the phone to 6.0.1. and I would like to have a stock rom and a locked bootloader. (because I read that custom rom and unlocking bootloader affect to the function of the camera).
How can I do it?
I am getting different information over the forum and the internet, and I am getting a bit lost...
the security thing from service info, stays like this

htc one m9+ supreme camera

hi guys.
firstly its my very first thread so please ignore the poor posting.
i have a htc one m9+ supreme camera (m9px) hong-kong version.
after flashing a faulty SU the official/stock firmware went faulty and didn't boot back on.
i had to wipe the whole device to be able to try new rom or even firmwares. here is the problem i cant find anything for this phone!
sure i did manage to find a Taiwan version which i flashed but Baseband, radio and ota is not working.
i found a HK version on "easy-firmware.com" and "ir-file.com" but i think it was a fake one (check out the pic).

}
thus no chance found there. interesting thing is i didnt find the m9px recovery i managed to find a m9pw (htc m9+) and flashed it surprisingly its working , yet it seems because of the difference in models (hiau_ml_tuhl for m9+) and (hiaur_ml_tuhl for m9+ sc) every time that i want to install ota it goes to recovery and recovery cant flash the ota.
so if someone could help me out in any ways i would really appreciate it. or would you send a back up your phone (same model) to me to flash would be awesome too.
thanks again

How to unbrick Honor 7x?

I've been trying to fix this all day and I can't find anything that works. Basically, I successfully rooted my Honor 7x (BND-L24) running android oreo, using twrp and everything was working perfectly. Then I tried installing xposed framework and now it won't boot. It just gets stuck on the Honor screen. I can't find a twrp backup to restore to, and I've tried disabling xposed, but it doesn't seem to have installed at all. I also tried flashing the Xposed uninstaller, but it didn't work. I can boot into twrp using fastboot, but I don't know how to reset everything. It seems like the solution is to flash a twrp backup for this specific model, but I am unable to find one. If anyone could help I would greatly appreciate it.
You should flash over with 'HuRUpdater' the same firmware you are on.
I guess it's:

ATT unlocked and its current state of SW

Hello. I have an unlocked ATT version of S9 plus.
I flashed unlocked firmware to it but after reading so many pie thread, I'm beginning to question if I flashed the phone correctly.
Its been receiving OTA update regularly and its on ARL1.
I THINK I read somewhere in XDA that if you are on truly unlocked firmware, phone must read xaa/xaa/xaa. However, mine shows xaa/xaa/att? (currently on mintsim service which uses tmobile network I believe)
Can someone tell me if I did anything wrong as I have limited knowledge of android phones and I would like to correct it before pie update.
Thanks in advance.
You should be all good. The last one is showing the original software provider version that never changes from flashing carrier firmwares or unlocked firmwares. Basically it shows what the phone was born as I guess is a way you could look at it.
Bought mine directly from Samsung and mine also says that.

How do I deroot my v30 and upgrade to official Pie firmware?

I rooted my V30 awhile back on Nougat, and now I want to restore to official firmware and relock the bootloader using these instructions:
Guide: How to upgrade/downgrade/restore official firmware on your V30.​Is it possible? I found the new patched version of LGUP for Pie from another thread, but when I try to flash an official Pie kdz using "upgrade" it is giving me an error something along the lines of "0x4 cannot cross flash model h932 to h932" for some reason. I will pull up a picture in a little. Any idea why I can't do it this way, do I have to use partition-DL and overwrite? Is there any way I can do this without losing my user data?
I originally rooted my phone using the instructions here:
[ROOT] H932 - lafploit 1.5 up to v20a
WARNING DO NOT LET YOUR PHONE REBOOT, OR POWER OFF UNTIL I TELL YOU THAT IS WHAT YOU NEED TO DO. If you do, I am not sure what shape your phone will be in. This should go without saying, but you MUST have your bootloader unlocked...
