Root [Virgin Mobile] Android 4.4.2 VM SPH-L710

You can flash an older rom as long as it does NOT contain a bootloader. Trying to flash an older bootloader while on a knox bootloader will result in a hard brick.

Now an older rom may or may not play well with the newer baseband so you could possibly get a soft brick if it doesn't, but it's at least fixable.

So this is like 4.3 mk5, the roms I flashed with 4.3 mk5 bootloader(knox bootloader) will work, because I have flashed them on knox, and those roms never flashed a bootloader.

but what you are saying is crazy!!, its like saying that flashing a modem(baseband) will softbrick your device, in no case have I heard that happening, I know the apn fix from moped works, I have 4g on the 4.4 touchwiz rom, so the new radio should work with other roms( ill confirm when I flash cm11 snapshot m3) but I was just saying that seemed very wrong.

**edit** I meant that I flashed those roms that I had saved on my computer, while I had the 4.3 knox firmware(aka bootloader), so all of those will work, as they don't include and flash a bootloader, so all these roms will work
