My OnePlus 3T recently got a bootloop issue (stuck on boot logo).
Bootloader locked, stock ROM and unrooted device.
How can I recover my data?
I've already tried wipe data and reset system setting from recovery mode on my phone.
I have a pc with Windows os and another with Ubuntu os, if this can help.
On Windows i can see "Qualcomm HS-USB QDLoader 9008 (COM3)" on "PORT(com and lpt)" menu under "Device Manager".
I read many forums, but i find only this 2 solutions, that doesn't work for me:
1- Use an app on Windows called Android Data Recovery, but to use that i need to have USBDebugging setted on and i think i don't have. To do that you need your phone on and setting developer option enabled but i can't because stuck on boot logo.
2- Install a custom recovery to get data from phone storage. To get a custome revovery you have to unlock bootloader but i can't because to unlock bootloader i need to erase my memory.
My priority is get data from phone, if anyone can help or have any suggestion is really appriciated.
Ps: I find a way to connect phone and pc on Windows with USB cable. Using from Windows terminal the command ADB devices, it returns that my phone on "sideload" mode. I read there is a command "abd sideload file.zip" that flash your rom with file.zip, but i don't understand if this operation delete your data.
