Question Change rom - Samsung Galaxy S21 Ultra

Hi, sorry about my probably noob question, but I prefer to be noob than brick my phone
I bought on ebay an G998N (a lot cheaper than here in Chile), but I want to flash the G998B rom (both Exynox).
It is possible?
Thanks!

Nobody knows?

Make X1 normal again - Want to sell it

Hello,
I have bought my Xperia X1 on December 2008. In the meantime I have had a lot of roms.
But now I want to sell my phone. Don't know why, but just want to sell it.
My phone is from Orange / One Austria.
Which rom should I install? I think I need a stock rom but which one should I take for a device from Orange Austria?
What should I do after a rom install? Should I install the STOCK_SPL ?
Thanks for your helps.

You've answered all your questions ..... install an austrian rom, and after that install stock_spl.
Your answer is in sticky threads in this forum, just search, i can't write it any better, couse you have step by step guide for making it "stock" again. In short version, FIRST flash stock ROM, than stock SPL. Or maybe first ask the buyer if he wants custom ROM?
Ok thanks. I was not sure, because there are Austrian roms of T-Mobile.
But that makes no sense? Just any Austrian rom.

[Q] Debrand T-Mobile

Hi all, I'm approaching to the world of htc hd7 for the first time... I' m waiting for my new htc hd7 t-mobile coming in a few days and I'm asking if there's any way to debrand it and install a clean european rom with my language (I'm from Italy)... Can you tell me where to find the instructions and which is the last european rom? thanks in advance.

I have almost the same issue. I'm brazillian and the English keyboard doesn't have "ã" and "õ" characteres... I want to use Spanish keyboard because of this, so... Anyone could help?
Is it a US T-Mobile HD7?
If so, I believe a goldcard is the only way to debrand. See this thread.
I'm still trying to figure out if the benefits (quicker updates, etc.) outweigh the issues introduced by using a European radio.

Yes It's a T-Mobile US, I looked at that thread... It's not so easy and It needs some items as an usb y-cable, a sd card, a card reader, another smartphone with android...
thanks anyway...

[Q] Locked to UK carrier want to use on French carrier.

Hi All,
I've seen a second hand I8190N (S3 mini) for sale that's locked to a UK carrier. I'm wondering if I can just flash the firmware with the unbranded French firmware...
I8190NXXAMG1.LPMAMG2 ( I believe)
so I can use it with French carriers?
I've had a read and a lot of people obviously say use the one for your carrier for warranty purposes. I'm not bothered about warranty in this case.
I did read one post saying you can flash any ROM but the phone will remain SIM locked?
There's so much info out there I'm struggling to find an answer. Anyone know the answer or point me at it?

Just read all that. No one posted back to say it worked for their s3 mini. (7 pages of attempts though.)

Question About SM-G998U

Hi. This question might e already posted somewhere in this section. Apologies in advance.
I've been an avid fan of Android since 2009. Have a little bit of knowledge flashing custom roms and whatnot. Well this was 10 years ago when i first experience Android Gingerbread version. But due to limitation of android device back then i decided to switch to iOS. And that what I'm using up until yesterday. Now I am a proud owner of a brandnew S21 Ultra.
Now my question is since i got US Variant (SM-G998U / Snapdragon / Single Sim) can i flash asia rom on it? Let's say stock HK ROM from sammobile. Wiill it work?
Due to limitation of s21 ultra available here in PH and forgot to mention its already phased out. I end up buying in online.
I really want to flash stock asia rom with my s21 ultra.
I am seeing that i need to change CSC? Which i already forgot because is been many moons ago. Hoping for help.
