thanks in advance
Thank you for sharing this software with us sir.
Does it work for L01 European G7 too? I think if It does, I'll need to configure gps file later, but I'm talking about normal functions of the mobile, be able to make a call, wifi... etc
Thanks again! Hope you can answer this, bye!

anyone tried the new oneui 3.1 on the s10 lite . The One UI 3.1 update for the Galaxy S10 Lite is seeding in Spain now
i want to flash it but i am afraid if it doesnt work well as my csc is LYS not PHE .i know it is safe to flash other region firmware as long it is the same model but maybe samsung has changed something in android 11

If i remember well, you can't flash other regions any more that simple. You must use odin patched and flash another csc file, or something like this. So you are right not to flash it before reading!

S9+ Soft Bricked (efs)

Hi, after flashing stock firmware through odin, my phone is stuck on the samsung logo. My phone is the UK O2U variant of the SM-G965F. When the phone is stuck on the samsung logo, it shows up in chimeratool as "unknown samsung phone in modem mode" so I assume this is caused by the efs partition being ****ed, so the OS can't initialize properly.
When entering recovery I get the efs invalid argument error. I have tried resetting data and cache in recovery and then reflashing stock firmware again, but that didn't seem to help. I can't flash TWRP because the bootloader seems to have relocked itself, as I get an error that only samsung firmwares can be flashed.
I purchased a piece of software called "chimeratool" for 80 euros, but I don't have the option to repair efs for some reason, i think maybe because of the bootloader being locked.
If anyone knows how I can flash TWRP without booting or any help would be greatly appreciated. I can give a monetary reward if anyone manages to help me fix this.
have u flashed the latest firmware for ur phone ?

yes, the firmware i have flashed is named "SM-G965F_O2U_G965FXXSEFUB1_G965FOTFEFUB1_G965FXXSEFUA1_G965FXXSEFUB1" which i believe to be the correct one for my UK O2 Single Sim model.

Please see the attached photo
I have the same version of tab you have. I tried flashing a12 korea region via Odin on a11 egypt region and ended with hard brick and changing motherboard.
So i recommend waiting a little
Or see this post on how to upgrade on another region from a11 to a12. But i think i can still work for a13

Can you show CSC part from software information also CSC can be changed using MTP and ADB without format using Samfw 3.31.
Though Korean variants might have issue
