Im wondering Is it safe to perform factory data reset with H83020i_un ROM, or more precisely, can that result with sim lock on T-Mobile ?
H83020i_un ROM is H830 variant that was sold through Ebay as unlocked phone, but it is actually unlocked by modified ROM, and any update or change of ROM would lock it.

Hello, just bought a T mobile Sensation 4G from ebay, it came SIM unlocked.
I really need this phone to stay unlocked, so my question is, is it safe to perform a factory reset without losing my unlock? Is there even anything that can possibly remove my unlock? such as rooting and installing custom roms.
Any answers are highly appreciated.
Sim unlock has nothing to do with rom or factory reset so you should be good
Hi,
My friends Samsung nexus s is stuck on the X screen. since the phone is on stock rom and no recovery installed and he doesnt want to root his phone and wants all his previous data back, what should i do to get back in orignal state without loosing data?
Well, if you unlock the booloader, then his data is gonna be lost anyways because unlocking the bootloader will factory reset the phone. The only way to get his phone working again is to unlock bootloader, and flash the firmware images, or a custom rom through recovery. Your friend is going to have to accept the change on his phone and data lost. Sorry, but I can't think of no other way to restore it WITHOUT losing data.
I purchased a Factory Unlocked G-920i (in US) and want to use it in Europe. Is it correct that I just need to make a 5 minute call in US with a US SIM card and it will be region unlocked permenantly? Will the phone "relock" if I do a factory reset or install a new ROM? If so, is there any way around this?
Thanks!
Hi!, I have an XT1548 Virgin Mobile Moto g 2015, the phone is sim unlocked and i want to flash CM13 on it but i want to know if i will lost the unlock flashing the new rom, i don't know how the phone was unlocked but i did a lot of factory resets and the unlock is still there.
No, you cannot lose your official SIM unlock flashing a custom ROM or factory image... The SIM lock/unlock information is held in the same encrypted areas as things like your IMEI and WiFi MAC address, you can't access them using normal means and anything you do to your device should not be capable of change/modify those things.
i need help with e-sims because i never used one. i want to know if it is safe to use e-sim if i change custom roms more often.
my questions are :-
-- if my bootloader is locked and i add an e-sim, will it remain even after unlocking the bootloader?
-- will it remain if i factoryReset or hardReset my phone?
-- will the esim remain if i clean flash another rom?
i have no idea how esim are stored in phone so i need some little help because if i reset my phone and my esim is gone i have to request a physical copy and convert that to esim every time i switch rom.
Even I have this question and looking for the answer
I can tell you my experience with an Esim and Sprint. First off with a custom rom like LineageOS it doesn't work with Sprint. BUT every time I did a factory reset or flash another rom or flash back to the factory rom my phone activated right away. Again this is only with Sprint so I can't say for other carriers. Only time I had an issue was when I purposely deleted the Esim but was able to activate it again with My Sprint App.
