Hello

I have an unlocked S9 + US from the operator Sprint:
model's number: SM-G965U
Version : G965USQU3ARG2
oeprator soft ver: SAOMC_SM-G95U_OYN_SPR_00_0089
36514b5658543098
SPR/XAA/SPR

unlocked with them : https://store.unlockboot.com/unlock-samsung-phone/

It works perfectly with my french SIM but I want to flash it with an official samsung US rom to eliminate all traces of the sprint rom, could I still use my French and Algerian SIM please? Any risk with a standard flash? Where can I find the stock rom?

THX

dont flash a USA carrier firmware set for it (theyre not ROMs when you flash them in Odin, theyre called firmware). Flash the firmware with a multi CSC, preferably one that contains your needed CSC

that error wont cause any issues other than just plain being super annoying. Each USA carrier has something stupid built into their firmware that causes silly headaches like this. If you get a notif in the pulldown area, you should be able to long press on it and tell android to ignore it. If not, you might just need to find the U1 version of android 10 and flash that on your phone so it doesnt know its a sprint phone anymore. Phone amnesia for lack of a better way to describe it LoL

you can install a French version if you like, but the U1 version is the unbranded version and you can just pick whatever language you want upon install. Honestly, i would just flash this https://www.sammobile.com/samsung/ga...U7DTA5/314795/ by using patched Odin which can be found here https://forum.xda-developers.com/and...-13-1-t3762572
