Until recently, I'd been able to flash just about any SS-compatible ROM to any slot with little to no issue. Some required flashing of GApps, or Kernels, but aside from a few FC's or signal issues, the actual flashing portions always went smoothly. I ended up flashing DarthStalker vX1 to my stock slot with the MK2 kernels and have had zero issues with the ROM functionality. Being curious about recent developments with other ROM's, I decided to try flashing a few. The problem I'm having is that 90% of the ones I try to flash are going into a boot loop. Even those that worked previously (Hyperdrive, SHOstock) are boot looping.
I have tried deleting and recreating various ROM slots and at one point I managed to get SHOstock (SS) 3.0 to boot, but all of the GApps were crashing to the point where it was unusable, regardless of GApps I flashed over it for testing purposes.
I guess I'm wondering if there may be some sort of issue with having a custom ROM in the stock slot? Perhaps some sort of file or data corruption that is stopping these ROM's from working, even though they all worked previously? It just doesn't seem to be making sense because I don't believe I've changed anything since the last time I was able to flash to any SS slot. I've tried searching, but pretty much all of the boot loop issues I've come across were related to something that I've either already ruled out, or simply didn't apply to my configuration. Any hints or tips would be great. Please let me know if anyone needs more information about the config, or steps I've taken so far. Thanks all!
