Download Stock 2.2.1 Nandroid Backup
Use our Clockworkmod Recovery image to flash.
Any other way to go back to stock 2.2 on a Cricket Zio?
This doesnt work for me, Ive tried flashing it in Recovery, it started to flash then rebooted. The old rom was still on the device, but the boot-up screen changed back to Cricket. (That was the only thing that changed.)
When I tried to restore this file using Rom Manager (which I hate), it kept giving me an error: "File Name can't contain spaces" or something to that effect.
Tried renaming the file several times, even just naming it "1.zip" made no difference.
All the roms on this forum are just way to slow compared to the stock rom. The only exception being the 2.1.x Rom here (which runs fast.)
Microsoft Activesunc/Windows Mobile Device Center isnt available to me as Im running Windows 7 64-Bit, the Windows 7 "Sync" program in accessories doesnt even recognize the device.
Fastboot into CWM works tho.
I know this phone pretty much sucks, but my daughter loves to play games and youtube on it, thats all we use it for. Some games arent compatible with Android 2.1..
Although I havent booted this phone up for years, I still disagree. OpenZio ROM far surpasses the stock ROM in performance, benchmarks and snappiness.
But if you are insistent on returning to stock, try formatting /system in CWM's advanced settings, then flash the backup.
Alternately, you can always run the 2.2.1 update to restore to a completely stock, unrooted system.
