TRWP Install help

You did the unlock bootloader bit in settings?

Hi cheers for replying.

Yeah I've unlocked bootloader in settings.

not sure what I'm not seeing.

Love to help more, but I've always used linux to fastboot.

Pretty sure with my swift the erase cmd didn't work for me, but the flash sudo fastboot -i 0x2970 flash recovery '/home/XXXX/Downloads/crackling-t0x1.img' did

Have you tested fastboot with any other devices? just as an experiment

I am trying to install TWRP on my swift.

I have installed android sdk and google drivers. Windows 10 adb and fastboot dont see the swift.

ABD shows no devices listed

Fastboot shows "8bce440" when "fastboot devices" is run

fastboot -i 0x2970 erase recovery sits at "waiting for any devices"

I have uninstalled sdk twice. Restarted laptop. Tried two different usb cables.

I am stumped. Any help guys.

If you see the device when command "fastboot devices" is used,
just enter "fastboot erase recovery" without the -i parameter.
This worked for me.

i have cm-13.0-20160127-NIGHTLY-crackling-recovery.img installed, should i do the erase? i just flash it using TWRP 2.8.7.1, it is working when i install the cm13.0 but i couldn't install gapp - just hang. Is this the norm when changing the recovery? also can i revert back to the previous recovery img?

I would replace the nightly recovery with the TWRP recovery img, because it has more options and you can backup your whole system.
So yes erase it and flash TWRP .8.7.1 recovery.
Are you stuck in a bootloop?
If you have intalled TWRP recovery boot into it and under option Wipe format the system and data folder (carefull your data will be lost!!!) . After that flash the nighthly rom again without gapps and check if you can boot.
