I have my HD1907 (T-mobile variant) on the international firmware and I am wondering if it's possible to keep the same firmware but relock the bootloader? I am getting ready to sell the phone and want to make sure it will work with all apps (I know some banking apps, and GPay don't work on an unlocked bootloader)
Or do I have to go back to T-mobile firmware?
Best to msm to TMO before locking BL

Simple question but can't really find the answer online.
Bought an H815, no carrier label etc. My ATT sim works in it.
I want to unlock the bootloader (OEM process) root, add TWRP and flash custom ROMS. Will this affect the factory unlocked carrier status?
How is it carrier unlocked btw , at the hardware level or bios type process? I see the H815 comes factory carrier unlocked?

Assuming your phone was purchased sim free, then no, bootloader unlock shouldn't affect it. You can always make a backup with SALT first (bootloader can be locked when you take the backup) so if for whatever reason it does get removed then you can restore it.
Btw, LG's don't support fastboot oem unlock. You need to do it via Official LG bootloader unlock website or UsU (look here in the threads) if your device isn't supported officially - if it is an EU H815 it official should work though.
fr eBay sim free. I'll look into the SALT backup.
I did a bit of work already and signed up as an LG dev and do see the LG website process which I was going to do to start.
So then adding TWRP and a custom rom will not affected the carrier unlock as well?
thanks

i have h811 TMOBILE phone i got it unlocked. it was unlocked by tmobile.
i unlocked bootloader and carrier unlocked keeps it unlocked no matter what. ive flash this phone so many times.
thats just my experience
OK thanks, Had a bad experience w a Samsung Grand Prime which I do not want to relive.
I have such problem.
xt1789-04 with TMobile. Bootloader unloccked. Was unlocked sim to use not in USA. After that i cann't flash any custom. After intaling firmware from trwp oem became locked. Also cann't donwgrade modem firmware. Also try to flash customs from adb - got anther oem_locked
You can check the Tmo carrier unlock policy. But I think the carrier can not be relocked (I've use ATT àn VRZ before). It seems the modem fw had problem (maybe its own firmware) if it had not recognized the sim card. If you have the EFS backup, you can restore it.
If you're bootloader is relock, no, the custom roms do not relock the bootloader. The unlocked bootloader can be relocked but can not be relocked as stock.
I converted my T-Mobile 7T to the international version and I was looking to relock my bootloader. Is there any risk to this or something I should do before hand?
Thinking I should factory reset and remove magisk but wanted to hear your thoughts. I could also convert back to TMobile if that's safest.
Thanks!
Hello everyone! I have a Oneplus 7T (HD1907- The T-Mobile Variant) and I want to install Pixel Experience on it. I have heard that there are troubles because of it being that specific model. Could you list me the exact steps I should take to install it on my phone? I'd also like to make a current backup of the software I'm running currently. (11.0.1.2.HD63CB). I have not unlocked the bootloader, installed recoveries and neither rooted the phone. Please guide me correctly. Thank you!
[CLOSED] T-Mobile 7T Conversion to International WITHOUT unlocked bootloader/SIM unlock!
Here is a patched MSM download tool for TMobile OP7T. It will bypass the need to sim unlock before unlocking the bootloader, and will also bypass the need of an unlock token file from OnePlus (hence skip the wait period of 1 week to get the...

Bootloader is not eligible for unlock (not at all surprised) for the XT2075-2. Has anyone found a way to unlock the bootloader or generate a bootloader unlock key (even if it is a paid service)? Worst case, it would be nice if there was a root exploit that could be used.
Well this is frustrating. I bought the unlocked version xt-2075-3, but received the ATT version (xt2075-2) It appears the unlocked version doesnt have 5G for USA anyway... So I am ok with the ATT version... But youre saying I cant root this thing? Wtf?
