I was downloading some application on cydia and then my iphone said it need to reboot so i clicked reboot and it was just stuck in a constant reboot. I plugged it into my computers connected to itunes and it recognized in recovery mode. i tried to recover it with custom firmwares on my computer that have worked before i also tried to recover and update to 4.3 but it just kept on showing up with errors basically every error you can think of. I put it in DFU mode but still same thing. I tried the ireb but it didnt work either. I need help, ive been tring to figure it out all night but havent had any luck. i used redsn0w 0.9.6rc8 to jailbreak it and unlocked it as well. its on 4.2.1 firmware. Please i really need to fix my phone. i dont care if i lose everything i just need it to work.
