So I have a N975U1 Note 10+ model. I am currently trying to flash the N975U VZW firmware to it but I have a major issue...
The phone is currently on a bit 4 firmware (N975U1UES4CTF2) and the latest verizon firmware is a bit 3 firmware (N975USQU3CTE7)
Now I know the flashing issue is to do with the bit version not being able to downgrade via odin which makes sense. (SW REC CHECK FAIL: LabllFused 4 > Binary 4)
Am I just stuck on the unlocked models firmware until carriers send out a bit 4 FW?
Yes. It has to be the same or higher bootloader version

Is it possible to flash an earlier firmware than is on my Edge?
I had 3 UK firmware, latest version. Probably 5.1.1 or similar.
I flashed the UK non branded Marshmallow firmware. I wasn't impressed so tried to flash the 3 UK firmware back but although Odin says it succeeded without problems, the phone just boots over and over.
So, I re-flashed the marshmallow UK firmware and it is working again.
I would like to return to the earlier 3 UK firmware if it is possible.
Can it be done or am I stuck with marshmallow?
I would say yes you are unless im mistaken

Oh well, I will have to get used to it until a 3 UK version of marshmallow is available.
I apologize if this is a stupid question since there are several threads about flashing different firmware.. Having not had a Samsung phone since S7 Edge, the process seems to have changed a bit. I bought a Verizon S9+ from a family member for cheap and I'm currently a subscriber on T-mobile. I'd like to flash over to the T-mobile firmware.
Current Baseband is G965USQU1ARB6
I believe this means that I'm on the v1 bootloader.
My understanding is I need to flash to the U1/unlocked firmware without a SIM and then flash to the T-mobile firmware after that. Correct?
Any rationale to picking a specific firmware since it appears there have been several updates since my current one? I assume once I get T-mobile on there I would get OTA updates via T-mobile from then on, correct?
Also, when I switch to T-mobile will I be able to get on the 600 Mhz Band 71 for T-mobile's LTE or are the radios actually different in the different carrier versions of the phone?
Thanks in advance for any help, and I'm sorry again if this is a stupid question - just having a hard time with the changes in firmware flashing that occurred after S8 came out apparently ://
The radios are identical between all U and U1 models, but the firmware isn't. You will find a Verizon phone won't work on TMB without flashing for several reasons (wrong APN which isn't editable, for one).
The latest U1 build is ARF4. That's also available as a U build for TMB. Flash to the U1 then to U. Use normal CSC so it will factory reset both times. You'll be golden.
If you want to be able to switch again, I recommend you block any updates TMB pushes once you're back on U, as newer U builds update the bootloader and you won't be able to flash back to U1 until it gets updated.
Good luck.

Thanks for the reply! I flashed the U1 firmware and used normal CSC to factory reset. Then I flashed the TMB one. When I boot up it still says Verizon and the software version says VZW/VZW/VZW still. Should I have inserted the TMB sim prior to the second flash? Did I hose myself now that I've flashed the latest version and its still VZW? Thanks

If you took TMBs newest OTA, you're screwed. You'll have to wait for an updated U1 build. No one knows when that may arrive.
Recently bought a used samsung galaxy s9 plus. It is stuck on android 8. When I try to update it it says that I'm already on the latest software.
When I tried to search for firmware to flash manually I got confused because CSC is XAA which refers to unlocked version but currently installed firmware is of some carrier I guess...
Can anyone please suggest me the correct firmware which I need to flash in order to get Android 9 with one UI.
See attached screenshot for exact number firmware installed.
Flash a higher binary firmware using Odin. Make sure you use full 4 file firmware. Also remember to backup your files

Your model is SM-G965U1

Download soft using SamFirm program
Hello!
First of all, I'm a novice and have no knowledge of how the firmware is constructed, e.g. wrt any dependencies between BL, AP, CP and CSC. I've searched the S9+ forums without finding answers - I have however found threads concerning downgrading but they seem not to answer my exact question.
I'm currently on the latest build of Android 10 for my region (SM-G965F, 965FXXU7DTAA). Completely stock, no modifications.
I read in an S7 thread that someone had been able to downgrade to a previous FW version with a lower BL version than the phone currently was on by doing the following:
- downloading and extracting the FW wanted
- removing the sboot and the modem parts of the firmware
- repacking the remaining parts
- flashing with odin
According to him/her, this worked, the phone booted succesfully, even though he/she at that point hadn't yet tested it to the full extent and in all aspects.
My question: Would this even be possible for the S9+? I.e. only flashing the AP and CSC parts of the desired FW via Odin while leaving BL and CP parts untouched? Would it even work, and if so, is it possible to say/know anything about adverse effects. Is the phone likely to brick? Knox?
Excuse me if this is obvious to you all, but I'm curious about this as I am currently not satisfied with Android 10.
I should add that I'm aware that it is currently possible to downgrade to latest version of Pie the "regular way", but I'm looking for options, if any, to go even further back

admittedly, i TL : DR all of it, but on the S7, downgrading the bootloader was possible for a while, thats not the case here. You can only flash F/W with the same or higher BL version. If there is an android 9 version available with the same BL, then you can flash it all you like. www.sammobile.com/firmwares is where you need to go to look. But use the frija tool or SamFirm to actually d/l the zip unless you like wasting 2 hours of your life
Thanks for the reply
I'm aware that I am able to downgrade to the latest version of Pie, which has the same version BL as my current Android 10. But my question is rather if it is possible at all to flash only the AP and CSC sections of a previous FW (with lower BL version) and leave the current Android 10 BL and AP untouched as it is on the phone?
Sorry if I was unclear in my first post

As long as the previous firmware is the same bit number you can flash either. You would have to flash all the files as the 10 bootloader more than likely isn't going to boot pie. 5th Digit from the far end of build is your bit number.
Thank you for your reply - good input wrt 'bootability'.
I'll downgrade to the latest version of Pie the regular way.

Hi. I have a Galaxy s21 from EE with EVR firmware (EE firmware) and I’ve tried flashing BTU and other UK networks firmware on it using Odin but that doesn’t work. Every time Odin says it’s passed, it hasn’t changed the firmware at all and I’m still stuck on EVR. I’ve tried SamKEY but it’s saying it doesn’t support my firmware (G991BXXU3AUGM) so I’m not sure what to do.
Any help would be appreciated. Thanks.
I have a US S21 but am also in the same boat, and sadly I think the only way at current is to wait for SamKey or to downgrade to a firmware that'll support SamKey.
I've tried ODIN flashing my US TMB S21 to try and get it working on AT&T fully many times over, but the CSC is locked up tight and SamKey was the only way to get it done for me. (Sadly, my CSC reverted when I stuck another TMB SIM into the phone and it locked the CSCs again so I have to pay for SamKey a second time if I want my AT&T SIM to work fully again. Yaaaaay.)
Samsung really needs to hurry it up with the auto-config firmware for the S21s.
I haven’t got a clue on how to downgrade it, any idea how?

(Sorry for the delay, yesterday got busy.)
For downgrading you'd just need ODIN and the desired firmware to downgrade to, just making sure the binary version matches (in this case, the binary version is the first number of the last 5 characters of the software version. So in the case of G991BXXU3AUGM, you'd be looking at "3AUGM" and in that case, your binary version is 3. So you can flash any firmware that's 3XXXX). At least that's how it is on Snapdragon models.
If you've no idea how to work ODIN it might be worth it to just wait. Plus, downgrading would incur a factory wipe (and restore with Smart Switch, which doesn't necessarily restore all settings and such.)

Thank you so much for your help! I managed to flash BTU firmware by downgrading then using SamKEY. Much appreciated!

hi, can I flash a HK firmware to a US unlocked single sim model? I'm dying to get esim working. any idea?

HK is very likely Exynos, so no. You can generally flash software from other variants so long as the CPU matches (most of NA uses Snapdragon, for example. You can't flash Exynos firmware onto a Snapdragon S21.)
