I'm assuming recovery mode would be part of step 2:And your phone is in recovery mode, correct?
"Unzip the SBF file that you downloaded in Step 4 of "things you're going to need" above. This will produce the file MC1_A855_1282081087_Recovery-Only_SPRecovery_0.99.3b.sbf."
So step 2 should say copy unzipped file 'MC1_A855_1282081087_Recovery-Only_SPRecovery_0.99.3b.sbf' to SD card? That I didn't do.
It's at the bootloader screen. I've followed exactly what the directions stated, did nothing more, nothing less.
