Hello Everybody,
I have a Galaxy S21 (SM-G991B) 5G, and I tried more than 10 times to downgrade the software but I just can't.
all the ROMs are available (Android 12) Under security patch level 7. I don't know how to handle it.
Any ideas, please?
Btw, The Reason I want to downgrade my Android system is because the camera keeps falling and I just tried everything, Force quit, Factory restart, Wipe Cache, another ROM.
if you have some ideas about what to do, it is welcome !
I don't see any Android 12 for bootloader version 7.
I see them under bl 5

Maybe there's another source.
But make sure to use patched Odin.
Patched Odin 3.13.1
For those looking for a modified, modded, or patched odin that is a newer build than all the fake and renamed prince comsy 3.12.3 versions floating around. I patch recent Odin versions to offer similar functionality to the princecomsy; in that...

Hello All,
Is there a website to get the latest firmware with fast downloads without having to pay for premium service? Sammobile is downright annoying, and I believe any Android firmware should be open-source and free to download and flash. My Galaxy is stuck on Android 8 since I don't have a WiFi network to update it with.

While websites are annoying with download speeds but for the latest firmware for you phone you can use PC apps like samfirm ( old out dated but still works ) or frija

Hello:
I have a problem with my S9+ SM-G965F. After updating to Android 10. The screen freezes, it stays black, you only see a line at the top, let it rest for a few seconds and everything returns to normal.
I have tried with several official and cooked roms, but the problem persists.
I tried to Downgrade from Android 10 to Android 9.0, but my firmware binary (G965FXXSHFUJ2_G965FOXMHFUJ1_PHE) is B:17, and when I try to put an Android 9.0 firmware through Odin, it gives me an error: sw rev. check fail (bootloader) device 17 binary 15...
How can I solve it? Since I can't find an Android 9 firmware with binary 17.
Thanks
Hello.

Thanx in advance.
Combination Firmware... I have no eToken...

Need to download G965FXXU2CSC8
This what I had on Device:
G965FXXUHFVG4
And this I downloaded for stupid tests:
G965FXXUHFVB4
Both are UH aka Bootloader Version 17...
Both I was able to download from:

I have downgraded to FVB4... to have chance to play with the Delta File aka update.zip....
Maybe with TWRP or with something else I can replace sboot.bin in update.zip....
For now i will chek if older sboot.bin is written... under Root:
Code:

Mmmmh... out of luck with sboot.bin...
Seems no public way without "JTAG" to clear RPMB...
New idea to check if I can start old Firmware with newer sboot.bin...
Memo to me...
Content of Combination Firmware:
Code:
boot.img
cache.img
cm.bin
dqmdbg.img
keystorage.bin
modem.bin
modem_debug.bin
nad_bigstream.bin

Not realized before... that SH is also Version 17...
Code:
AP_G965FXXSHFUJ2_CL22256834_QB44970093_REV01_user_low_ship_meta_OS10.tar.md5
So my SM-G965F is on this Version now:
G965FXXSHFUJ2
Isn't the bootloader unlocked on the Exynos variants so you could roll it back?
Android 9 is probably a better choice than 10, these originally were loaded with 9 I believe.
Everything after 10 is a mess... I have 2 N10+'s one running on 9, the other 10. Very unlikely I'll ever upgrade either one as they run well particularly the one running on Pie.
@blackhawk
Reason for rollback is emToken/steady.bin Research...
SH is November 2021...
But it seems I need maybe older sboot... for my tiny adventure...

There are probably some new unsold ones to be had (beware of scams). There are still new N10+'s for sale in the USA. They are factory loaded with 10. Same may be true for other models of this era.
Hi everyone,
My S21 is full stock and I would like to keep this way. My problem is that I do not have any Wifi and my mobile operator is blocking updates download. I have no solution to download OTA updates except hunting for a free wifi hotspot..
Is there any way to install these updates manually? Without making any factory reset?
Thanks!
Here's a site with firmware, search your model
There's other sites that might work better, just search Google for Samsung (model number) firmware.

Thank you for the time that you take to answer me. I am late of 4 updates, is it ok to flash directly the last one or should I flash all of them one after an other? Thank you.

You can flash direct.
To keep data flash home-csc not the csc_ one.
I would still backup before doing it, you never know what will happen.
If you're super worried try one version at a time, but you end up downloading a lot and waiting a lot.
Also with locked bootloader, to know in advance, the number in the last 4 or 5 letters is the bootloader version.
( G991USQU5EWAI for example)
In my case "u5" means i can only flash 5 or above.
If you see a new one with 6, as soon as you flash that, you can't flash 5 or 4 anymore.
I stick with May 2022 update cvdb because it lets me charge bands if I'm in an area with bad signal and I can disable 5g to save battery.
