Hello, I have the same problem I test this solution without success. The recovery mode has disappeared, I tried to flash a stock rom with odin and I have this message:
<ID:0/004> Get PIT for mapping ..
<ID:0/004> There is no PIT partition.
<OSM> All threads completed. (succeed 0 / failed 1)
So I try to flash the pit with odin again without success on my s5 with the following message: MMC: mmc_read fail
Thank you for your help
Sorry for my english
