Hi,

You may try to boot to safe mode. Just a thought. If you choose to do it, I am not responsible if it would not work or if something else wrong happens.

Good luck!

Method 1. Download Full ROM, and Payload Dumper. Extract payload.bin and put it to payload_input folder and all *.img files will be in payload_output folder. Use fastboot flash boot boot.img command and reboot. Device should work after reboot. If you need root, either flash a patched boot.img or use flashboot to flash TWRP and then install Magisk from TWRP.

Method 2. Manually flash *.img files. Reference: [GUIDE] Unbrick or restore to OOS using only fastboot

Method 3. Use MSMtool to wipe and restore your phone.

Note: If you lost WiFi AFTER your device is rooted, and if you ever installed a custom kernel, it's probably the RAMDISK (can't remember where I saw it before) causing the issue. Easy solution, flash same custom kernel again. Or try different kernels.

Im on linux right now im trying to find a way to install windows but even thats not working smh
I applaud your use of linux! Unfortunately, I've not found a good solution under linux to do what the windows MSM tool can do. I had to book in to a full Win install in order to use it on my phone as well.

On a positive note, it's nearly impossible to truely brick these phones. The negative is the MSM tool needs windows. Unless someone can point to a linux solution (which I'd love) you may need to find a friend with Windows and borrow their computer...

The fact you are in fastboot loop makes me think you should be able to just fastboot flash everything manually. MSM is the nuclear option. I'd try getting the stock full ROM and manually flashing everything in fastboot.

What fastboot are you using? I've found that the one in many linux distributions are old. Download the latest from Android https://dl.google.com/android/repository/platform-tools-latest-linux.zip and use this.

EDL mode will reboot itself if there was no command sent to the phone. So you need to run MSM tool first and once you see the phone is recognized, just execute.

A real Windows should make whole process a lot more easier. If you use a VM, as long as Windows can recognize Qualcomm Modem driver, it should work too.
