So I hate the new UI of A12, and theres a number of features that seem to no longer exist/work(scrolling screenshots, holding power button to bring up gpay, etc). Just wondering if theres a process to downgrade back to A11? Thanks
Yes, you need to backup everything, then load the correct a11 FW suitable for your carrier, IF your phone is unlocked that is.
You need to know the carrier, model number. If it is unlocked "RETail), you need the correct FW that matches your country.
There is another topic for loading stock ROM's

Hi,
I'm running currently running SlimRom 4.4.4 on my phone and want to change carrier from Rogers to {cheaper}.
I've found various unlock instruction for free but everytime I tried them I get errors when it starts USSD. With a bit of digging around I found that they probably only work on stock roms from Samsung. With the newer CRTC ruling Rogers is also required to unlock my phone if I ask them to, but I'm sure they won't have a clue and won't assist me with a custom rom on.
I've found the latest stock rom from Rogers (RWC-I747MVLUFOB1-20150310141610) which is 4.4.2 and was going to flash that using Odin, but then... I found warning about potentially bricking your phone by doing downgrade of Android (from major revision to another).
Is that mostly a problem going from 5.x to 4.x or do I need to take extra precaution to not brick my phone? I'm assuming that the modem and everything stock is in the base rom and I won't have issues afterward?
Appreciate the help!
The free method only works on a completely stock 4.1.1 ROM. If the phone is running a 4.3 or newer bootloader, you will have to purchase an unlock code. The unlock code can only be entered if the phone is running a stock Samsung dialler.
Yes, all Canadian carriers are required to unlock the phone once the phone subsidy has been paid off; however, the carriers are not required to unlock the phone for free. I believe Rogers will charge $50 + tax for the code.
Flashing the FOB1 ROM should not brick the phone. The possiblility of bricking happens when attempting to downgrade the phone's existing bootloader to an earlier version.

I've flashed TWRP on the phone to get my custom roms and rooted, so I'm not sure about my bootloader, did that not change when I flashed to get root or does it stay at the same version in most case?
The bootloader will not change when flashing TWRP. It is unlikely that a custom ROM would include a bootloader and, in fact, I have never come across a d2lte/d2can/d2att ROM that alters the bootloader or modem/baseband.

Good to hear! I'll flash back to stock tonight and get it unlocked then. Considering going with Koodoo and I think they do it for $35 but I'll try Rogers first.
I would order a code off ebay. Cost me $17 CAD for a Rogers code.
Many thanks that worked like a charm and I'm now back on stock 4.4.2... got a scare when Odin lost connection mid way! but I restarted the process using another USB cable/port and it went through no problem.
I've checked with rogers and it is indeed $50 to unlock, quite expensive!
I've found some reseller on eBay and will likely go with that. How does that work anyway, do you know? It seems fishy, but their sellers rating are mostly all good. I suppose there's no danger in sharing my IMEI?
I have used these people several times: http://www.ebay.ca/itm/Unlock-Code-...Rogers-Fido-/131547835629?hash=item1ea0dcaced
Cost is only $14 and takes a few hours to get the code.
Just purchase the item and include a note to the seller with the phone's imei, model #, and carrier.
Hi,
I followed this post to update my Note 8 to Oreo. I didn't read it carefully enough to realize that its firmware is N950U, which brings all the good bloatwares and carrier firmware. Now, I would like to revert back to Nougat 7.1.1 with stock/pure Samsung firmware. Before messing my phone up, the baseband version was N950USQU1AQI5. My phone's carrier is XAA (the phone is factory unlocked). I have looked everywhere to find this firmware but the only one I find that is XAA is N950U1UEU1AQI5, which is for the U1 models not U (mine is N950UZKAXAA).
Can some one PLEASE help me get rid of Oreo and this carrier firmware and restore my phone to the original firmware it shipped with?
i think Oreo might have the bootloader v3, so you probably cant go back to what it shipped with (bootloader v1 or v2). You might be able to flash BRA5 and whatever was right before it (which is 7.1.1) because that did have the v3 bootloader.
I think U1 is for the unlocked model, so I'm pretty sure thats what you'd want to be flashing.
1. Download SamFirm
2. put in "SM-N950U1" for Model and "XAA" for region
By the way, I think this is the wrong forum for the Note8
I'm sorry, i don't know what you are talking about.
Any chance you could help?
Hi,
I have a Samsung Note 8 Tablet, GT-N5110 that's stuck on the Samsung logo.
Any chance you could help me revive it?

My sm-N975U AT&T note 10+ has never ever received any updates.
It's currently at Android 9, N975USQU1AS12, security patch: September 1, 2019. Since I got it in 2019.
I see that the unlocked version SM-975U1 AT&T receives updates frequently and I can easily get the firmware online.
I've not even seen any Android 10 firmware for SM-975U AT&T.
So is it possible to flash SM-975U1 AT&T unlocked over SM-975U AT&T.
Or even just to make it US unlocked with no carrier so I can receive updates from Samsung?
You can flash the N975U1 firmware onto the N975U (and vice versa) so long as the bootloader is the same version (or higher) then what is currently installed on the phone.
Three things to keep in mind:
No way exists to downgrade the bootloader... So if you flash firmware with a newer bootloader and you decide you want to go back you will not be able too.
Bootloader version can be found by doing the following. Looking at your About Phone > Software Version look at the baseband version info.. Start at the far right and count 5 characters to the left (with the first character being the far right one). The number that is the 5th character in will be the bootloader version that is currently on the phone.
The USERDATA isn't always included with the U1 firmware should you desire the AT&T version of it. You should be able to find that in this thread,
For an example the red number is the bootloader version:
N975U1OYM3CTE7
For anything else this question has been discussed here a lot so you won't have any issues finding information about it.
So this will unlock the phone? Does the same go for the Sprint version?

You can flash the firmware from the N975U1 to the N975U (and vice versa). It doesn't matter the carrier, only the model number matters.
Just be sure to be mindful of the bootloader version.
Flashing the firmware from the N975U1 does not have any relation to the network/sim lock. For network/sim unlocking you will have to ask your provider to do this for you
The term (or name) "unlocked firmware" is derived from the phone it comes from.. The N975U1 is the carrier/network unlocked variant sold by Samsung.
so if i put the, U1 firmware to n975u and i'm out USA. now I will receive all the new updates automatically via OTA?
Excuse me, I am new to the forum, I have a question for you, I have an at & t SM-N975U, this at & t firmware does not update outside the USA, I am in Mexico, which firmware should I use, I want it to update automatically via OTA here in Mexico? t-mobile firmware or U1 firmware, I really appreciate your answer,
hello, my question is similar but regarding the carrier. My Note 10 Plus is AT&T locked, if I flash the SM-N975U1 over the SM-N975U, will that unlock the carrier so i can use anyone outside USA?
No. It won't. You'll have to have AT&T unlock it.

Hello can you please help me too
I'm super new here
So i have the N975U and i live in Europe and i don't get any updates cuz my Note 10+ is the AT&T version and now i want to change it to N975U1 so i can get updates from Samsung themselves.. from Sammobile i downloaded The N975U1OYM7GULD-(XAA) model and also N975U1OYM7GULD-AT&T model while the current one i have is N975USQS7FUI7 so both of them i think should work because they have the same bootloader so my question is since i want to get updates to which one should i flash my phone with? I heard the XAA is better because u get updates directly from Samsung themselves ( even when I'm in Europe ) and the AT&T version is also N975U1 but I'm not sure if i will be getting updates because now I already have the N975U ( probably AT&T model that's why I'm not getting anything ) So what do you think i should do?
I'd appreciate ur help
And sorry for my broken ass English hope you understood..

And should i use Odin patch or just the normal odin? I actually wanted to flash my phone with the Germany version but i don't know if it will work!!? ( You'd use odin patch you want to change region! ) so idk if it would work if i change it from N975U to N975F which is Germany model !!?
Hello guys. I am from Europe and just buy Samsung Galaxy S20 Ultra with Snapdragon. The phone is unlocked, but have carrier brand, Verizon, I want to remove it. Can't change phone language (see that this problem is discussed here, but I did not see a solution) and in Verizon miss Samsung Cloud.
I decided to try changing stock rom with Odin. Now downloading official firmware SM 988U, because I read that must put firmware with "U", and downloading SM-988USQU1CTLB (this is my baseband version and hope that this is correct firmware), write only USA, without any brands, from sammobile, I hope that is without carrier brand. Don't know if I will manage to change language successfully, because the phone is made for USA, but hope that carrier brand will disappear and Samsung Cloud will show. Will do this for first time and don't understand a lot of things. However, my question is for Bootloader.... I try to see if my bootloader is unlocked or locked, but can't do it.... If I put new firmware and bootloader is locked what will happens? Sorry for my stupid question, but I try to learn how things happen What you think, is my idea is good or no?
Something is bricks. I downloaded the original stock firmware from sammobile. USA only, I successfully uploaded it, everything with Odin was good, but after restarting and entering my sim card pin code, the phone want pin code to get app notifications. Please someone help me.... What is this pin code? I can only received phone calls
I manage to put the phone in downloading mod, please someone tell me witch firmware must download and install? The phone is SM-988U
I'm trying to root and update my friends T-Mobile 7T (HD1907) to the most recent generic ROM. She's leaving the country and has no need or desire to keep the T-Mobile branding, and getting on a generic ROM seems like it will allow for faster updates.
I've seen some threads that look like they might help, but having had issues in the past with other attempts on other phones, I know that one little oversight can cause HOURS of frustration.
So I figured I'd ask first and try to save the drama this time.
Where can I get the correct ROM to do what I want on this phone?
I have TWRP installed and have rooted with Magisk.
Current build # is 10.0.3 HD63CB
Carrier configuration version is 2.370001
I appreciate any help on this, thanks!

[CLOSED] T-Mobile 7T Conversion to International WITHOUT unlocked bootloader/SIM unlock!
Here is a patched MSM download tool for TMobile OP7T. It will bypass the need to sim unlock before unlocking the bootloader, and will also bypass the need of an unlock token file from OnePlus (hence skip the wait period of 1 week to get the...

The key is to force reboot into bootloader mode when u get stuck on pink T-Mobile bootscreen after first "flash-all" script so u can repeat this "flash-all" second try which will then work.
Thanks for that. I managed to unlock the bootloader and update to Oxygen OS 11.0.7.1.HD65AA, which I believe is the most recent global ROM.
The model of the phone still shows HD1907, which I thought should change from the T-Mobile model to the global model in this process, but perhaps this is normal.
Everything seems to be working fine, but I'm a bit concerned it won't update properly if its not entirely "converted" to the global model.
I did the same. All working fine though. It brought me unlocked bootloader to flash the dual sim firmware or global. All works. Only concern I have is ..The unlock bootloader ticker in dev options shows greyed out "Already Unlocked" but, the ticker is in the off position to the left which is odd. My friends was done by token but mine using patched boot msm. Any reason to be concerned ? Perhaps that's going to hinder the re lock and possible re unlock ?
