I needed to flash my phone back to stock using rds 4.9 and the full sbf vrza955 2.3.20. I got into the bootloader screen, connected to rsd, started the flash process. It goes through the entire process except stalls in the boot menu of liberty and goes no further. The liberty logo is still there and I have tried the process like 4 times. I have no clue what I am doing wrong.
