I am on the latest twrp.
format /data worked, and I have a OS again.
I have done a wipe of dalvik, system, data, internal storage, and cache + format /data and still get the errors.
I've done all the above probably 10-15 times in the last 48 hrs. the only progress I've made is I got the MF1 radio installed from internal sd after placing the newer version of update-binary in it, and re-zipping it.
I installed PhilZ recovery (latest version) the night before last and got errors from there on out. I've flashed back to twrp via recovery, odin, and goo.im since. (I tried a couple different versions between 2.5.x and now back to 184.108.40.206)
Edit: I've also put the newer update-binary in the carbon, pac, and gapps zips but still nothing. Tried flashing from internal and external.
