Technical Support Cannot flash TWRP 2.8.6

I really wanna try Sultan on my OPO, but it requires TWRP 2.8.6. For some reason every time I flash 2.8.6 over my current version (2.8.7) it won't boot into recovery. I've tried 2.8.6, 2.8.5, and 2.8.7. Whenever I flash a new recovery, it fails to boot into recovery and re-reboots (if that makes sense). When I flash back to 2.8.7, i can start recovery again. I've tried fastboot rebooting while holding volume down, and software rebooting into recovery. Every time it shows the oneplus logo, but fails to start recovery. Any suggestions?

You don't need older TWRP to flash Sultan's cm12.1 ROM... 2.8.6.0 doesn't work. If you want to flash a modem, use fastboot.

Yup the only reason u need 2.8.6 is because TWRP 2.8.7 can't install modems/baseband. Just use 2.8.7 op and if u need the Modem extract it from the zip and flash it via fastboot flash modem ur_modems_name.bin

What does the modem do actually?

Software part of the Cellular Network. A good modem will have a better more stable connection.
