I’ve tried to install twrp which worked but for some reason I couldn’t root it as it said /system, /vendor and /package couldn’t be mounted. So I tried to restore and installed the stock recovery from https://forum.xda-developers.com/oneplus-7t/development/recovery-unofficial-twrp-recovery-t3976961 But it didn’t work. This led to my phone being hard bricked. It’s stuck on the fast boot menu. I can’t find a mega unbrick guide like the other devices to fix it.
Did you try connecting it to the PC and run the command in fastboot mode
Oneplus service as in a physical store or the one online?
A physical store might be much better https://www.oneplus.in/support/service-center you can check from this site depending on your location
Thanks for the advice but all I have in my hometown is one service centre which isn’t even a oneplus exclusive service centre according to that website. Do you think they would understand what happened to my device, let alone fix it?
Ask for replacement on Amazon. Say it randomly turned off and wont start up. They might ask you to boot in recovery say nothing happens and they will send a replacement.
What do I ask for a replacement for though? Item defective or doesn’t work? How do I make them believe me?
Update, I’ve requested for an inspection service and it is going to happen after 24 hours from now. They’ve said that if the technician recommends to replace the device, a replacement will happen. However, if someone could provide me the msstool file for oneplus 7T, that would be GREATLY appreciated. Thanks a lot!
What do you mean for hardbricked? The bootloader is unlocked? You are able to enter in TWRP mode?
Is not hardbricked
actually is not possible, the oneplus 7t is using the new /super partition and on op7t is not possible to flash a full stock rom from fastboot, but you can flash all partitions except system, vendor, product (The 3 partitions that contains the rom), he should boot in twrp to try to restore his device, maybe i can help a bit, but it's something really new and i think the oneplus 7t is the first one that is supporting this.
