Hi! I have this problem. I looked up to fix it, but I couldn't find someone in the same situation. I was trying to upgrade my ICS 4.0.4 to the JB Leak. Right in the beginning I followed this step, "Use the Razr Utility to restore ICS to version 6.16.211. But in the process I noticed some "Fails" when the program was writing some files. I proceed and end doing a wipe data as the program asked. After this, my cellphone restarts directly to the AP Fastboot screen with a boot failure: I almost forgot. I tried to flash using RSD Lite, but I Got an error in the 6th step: failed flashing process. 6/19 flash cdt.bin Thanks!
