Which model is easiest to unlock the bootloader and install custom ROMs? I'm in the US and I use T-Mobile. I would prefer a phone that isn't carrier specific so is there a factory unlocked variant that works best?

I have a note 8 on AT&t prepaid. The bootloader is locked. I would like to upgrade to the 9. Is there a variant that works on AT&t prepaid that will allow me to root? Unlocked phone are just carrier unlocked right? Will the unlocked Sammy still let me root?
Thanks in advance.

I don't use AT&T, but yes unlocked phones just mean sim unlocked. Not the same as bootloader unlocked.
U.S. models are bootloader locked so no root there. Exynos models and N9600 are bootloader unlocked. You would need to check the available bands on those models to ensure they match your carrier, or wait until someone on AT&T confirms
Hello. I was iterested in getting a second-hand V40 which happens to be the US T-Mobile version. But i want to use it here in the UK. I've checked the specs and it seems to support all the band numbers which my carrier uses. But I have read that the T-Mobile V40s are somewhat restricted and it is not possible to root or crossflash. Does anyone know if it is possible to unlock for UK use? And if so, how?
Many thanks
What do you mean? Unlock is sum unlocking, root is root, cross flash is cross flash. Dont tell me you got the word unlock mixed up.
Rooting and crossflashing will not unlock the sim carrier for you to use as youll need to unlock before crossflashing. Also why not just go buy an unlocked variant as LG also has the US unlocked version. every manufacturer's unlocked version will always have more radio bands.
It's said that U.S. carriers almost always lock down the bootloader of a phone permanently. Thus, if a phone is carrier unlocked at the *FACTORY*, ie. it is not manufactured for any specific carrier, is it safe to assume the bootloader would be unlockable? Would this apply to a Samsung S20 FE 5G? Thanks
I live in Australia. Just bought an unlocked (carrier) 5G version and successfully unlocked the bootloader.
Nope, not the US variant unlocked model
Yea I wish I knew that before I bought the US unlocked one.
But I saw in another thread talks of flashing EU snapdragon firmware to see if it lets us US unlocked phones have access to oem unlock

Tried it, and it doesn't let you flash. But hopefully someone can figure out how to bypass that.....
I have the opportunity to pick up an AT&T unlocked S20FE, and was wondering if it is fully compatible with T-Mobile specifically for 5G/LTE Band 71?

The answer is, but you must flash the unlocked U1 firmware first and that will work or you can flash the T-Mobile firmware after.
You can stay on the unlocked firmware or flash the T-Mobile afterwards, no real difference. The only thing the AT&T version (flashed or not) won't give you is unlimited roaming on US Cellular. You need an actual T-Mobile branded phone for that.

If you are US based, or live in a "Google supported" country, buy a "SIM free" unlocked Pixel direct from Google. You could also get the Fi version which is the same but comes with an OPTIONAL SIM card. If you get the SIM free version, you can use it all over the world and you will have an unlockable bootloader. Be VERY careful about buying an "unlocked" Pixel anywhere else because many Pixel phones come carrier unlocked but cannot be bootloader unlocked.
