I'm currently on 8.0.0 version and I want to downgrade to 7.1.1. I need help with the downgrade version
I've tried N950USQU2BQLA and N950USQU3BRA9 and both failed.
My carrier is TMOBILE
Your 8.0 bootloader version is 4. You are trying to downgrade to a lower version. You can't.
And next time please read and search. The phone is now 8 months old, plenty of info out there !

If you don't mind me asking, why would it be impossible to downgrade if he's on U4? What would cause the process to be impossible?

What he wants is to downgrade to 7.1.1 which is possible if he is on u3(keep in mind i am referring to the bootloader version). On U4 there is ONLY 8.0. They did not release a 7.1.1 on U4 bootloader. Any time there is a major bootloader revision(such as u3 to u4 bootloader) Samsung blows a qfuse preventing older firmware from being installed(you can only flash firmware that is on the same incriment or newer) meaning if you are V1 bootlaoder you can flash either v1- v4 HOWEVER the moment you flash a higher version(if you go from v1 to v2) you are now stuck on v2 and higher and can no longer flash v1.
Based on the OPs provided information I assume he is on v4 bootloader because he is unable to flash v2 and v3 firmware. Because he is on the v4 bootloader he cannot flash 7.1.1 firmware which was last on U3. At this point his only option is to stick with U4 firmware(8.0 only).

Thank you for explaining this to me. It makes sense.
EDIT: I Google'd how to check which bootloader you' re on, and actually found a bunch of articles that seems to explain what you just did, along with being unable to flash custom ROMs.
I need to go from 8.0 to 7.1.1 too
Hi guys I upgraded this evening from 7.1.1 bqk2 to 8.0 2cql1
It doesn't work correctly I keep getting a black screen and the phone vibrates.
The only way I've been able to fix is holding power volume up and bixby and wiping data/factory reset
Is there a link to a download for my software and a guide at all?
Forgive me for the stupid question I can't find any info out there online or a YouTube video
Thanks in advance
Joe

Just to add the reason I'm uninstalling is every time I update the always on display app it is then that I get the black screen and vibrations. Until then it is fine.

Maybe try a factory reset (backup first!), or install a fresh copy of the firmware using Odin. You can find the files for your device/model on Sammobile, and then download from there or through SamFirm.
hello everyone I'm the only one to this discussion to try to understand and maybe solve my problem, currently on the 8th note I android 8 (R16NW.N950FXXS5CSA1) updated by mistake with software sam firm
I wanted to go back to Android 7.1.1 I tried to insert firmware (N950FXXU3BRA8 base) but odin gives me a failed installation, reading here in the forum seems to be the fault of oreo samsung changed BL / CP making it impossible to go back, I tried but I did not found files needed for downgrade thanks to everyone for the answers

Sorry You can't downgrade to nougat because you are on bootloader version "5"! (From your firmware version you are on N950FXXUS"5"CSA1, the number in "" is your bootloader version). Nougat only went upto bootloader version 3.
The current bootloader won't allow it to be downgraded only upgraded to v6 and higher.
There is no files (that I know of) that will downgrade the bootloader. You'll might have better chance on talking to Samsung and see if they can downgrade your phone.

so it was true that small article that I read on google that samsung stopped the downgrade ... damn therefore not proceeding gradually "4" up to the number "3"?

You can't downgrade the bootloader. Period. That actually why they change the bootloader version...to prevent you from downgrading.
I realized that my galaxy note 8 is not Italian but Europe on download mode me other carrier id
when I arrived for fear that it would not work in Italy I updated it with odin definitely wrong to bring it to android 8
Hello,
Today i got my brand new mi8 (from china).
Unluckily, it has some ****ty custom ROM with no actualisation feature. I can't even install offical global rom or unlock bootloader.
So I need to flash my device - and here's the question.
How can I flash my ****ty rom to a offical global rom? as this post says it's forbidden https://forum.xda-developers.com/mi-8/development/firmware-global-china-stock-firmware-t3818194
So should I flash to a china rom, than unlock bootloader and than install official global/some xiaomi.eu? Any simple solution would be great.
Thanks for help
UPDATE : I found hidden update app and installed global miui 9.6.1.0(OEAMIFD), but I still have ads in MI browser, etc. Will reseting phone to the fabric settings work?
I just got OTA Update to 10.1.1.0
Iam still on locked bootloader but want to unlock as soon as i can and flash AOSP
Is there any disadvantage like ARB when i update?
I think the ARB is just when going from one version of MIUI to a previous MIUI version. I think you should be okay when wiping everything and then flashing AOSP
Hi there,
Same question I have. I am on miui 10.0.3.0 and with twrp and rooted with magisk. /unlocked bootlooder of course/
Just got ota update to 10.1.1.0
Phone is global roms are official from xiaomi.
Rooting was a pain in the a** so I really dont want to mess it up about this encrypted issues…
AFAIK are all AOSP Roms for Dipper based on Pie. So it should be easier to switch the rom if your are already on a Pie based Stock rom. So go ahead and good luck for the AOSP-Trip. :fingers-crossed:
Hey there, downloaded miui11 from official site, wont allow me to upgrade via system update saying it's older than my miui10 what did i do wrong? Thanks in advance
Mi 9tpro global rom unlocked bootloader.

Hi, a few months ago I replaced the rom on my global phone with the Indonesia rom. Is it safe for me to install OTA updates via MIUI updater app? I heard that Chinese RN105G flashed with global rom gets bricked when doing so, but global and ID rom are very similar though.
i found a guide on ghizchina, where is explained that via twrp is possible and it's safe
