Experienced Rooter but noob to OnePlus - OnePlus 7 Pro Questions & Answers

Hi guys I have a OnePlus 7 Pro 5G im in the UK and my phone is totally stock. I've just read the guide for unlocking the bootloader and it mentions the phone needs to be SIM unlocked. My phone is locked to EE as it's the 5G version does that mean I carnt unlock the bootloader and install custom ROMs ?

Hi, yes unlock but unlock the bootloader. How can I unlock the sim ?
because even though i changed and i read that changing to a global version was not going to unlock the sim.
in the same way now my oneplus 9 tmobile. It is in global version but with the network locked problem.

Specifically:
Unlock your SIM. Some options here
Finding a sympathetic rep to unlock your device. I used the I'm a developer and need the device unlocked for work purposes and took 2 agents before I got mine unlocked.
Finding an awesome XDAer who has the capability to do it, such as https://forum.xda-developers.com/t/...ng-service-oneplus-samsung-google-lg.4231597/ (never used this service, just an example but he seems active and still unlocking)
Paying a (trusted) 3rd party service. I never used them, YMMV
T-Mobile's official policy of waiting 40 days and paying off any balance on an EIP.

What is it about the T-Mobile firmware that you hate? IIRC the only difference is international enables dual sim

I just hate the boot logo, bloatware and I heard the international firmware runs alot smoother plus gets updates quicker
Are you asking if the bootloader would become re-locked, or if the SIM would become carrier locked? Are both currently unlocked?
Once you are carrier unlocked you are always carrier unlocked. But flashing international wont make you carrier unlocked. You have to have someone on the T-Mobile side do that for you.

So would the Amazon renewed oneplus 7 pro tmobile gsm unlocked be permanently carrier unlocked?
MSM tool will not relock the sim. The lock is in the efs. And this is not flashed by MSM.so you are good to go. But before flashing ,if you are scared it will lock, you can use qfil or edl.py with the firehose programmer elf .and make a backup of modemst1 and modemst2. With these 2 copyed in the unlocked state ,u will be ok. I have locked and unlocked the sim many times for testing by having backups of locked modemst1 and 2 and unlocked. U can go back and forth all u like.alway back these up ,they will only work for your device. With the same HW I'd.
