My G935F shows “Could not do normal boot invalid kernel length” when attempting to boot into TWRP or turn on the device normally. The only thing I can access is ODIN. This happened after attempting to update TWRP and LineageOS. From looking online, I believe I can get a kernel and select the AP option in ODIN and flash a kernel as long as it is in .tar format. I was previously using PRIME kernel https://forum.xda-developers.com/s7-...1-4-0-t3678159 so I looked in the latest download from there but there are no .tar files, only a bootimg.tar.xz and a ramdisks.tar.xz. I tried extracting bootimg.tar.xz to a bootimg.tar and flashing that, but ODIN says it failed:

I also tried flashing the zip from https://autoroot.chainfire.eu/#odin but ODIN gave me:

I don't know what I'm doing and I'm afraid to mess up my phone beyond repair with ODIN. Can someone please help me? XDA forums has no answer and I don't know who else to ask.
