Thanks to ccapasso for the following:
Option A:
1. Use Kitchen (I didn't but I think it says it can do it)
or
Option B:
1. Mount your SD card, put the 1.6.2 img on your SD card. Unmount your SD Card.
2. Make sure SD Card is unmounted and USB Debugging Is enabled
3. Open a command prompt, and cd to your android-sdk-windows/tools directory
4. Issue the following commands (press enter after each)
adb remount
adb shell
cd /sdcard/
flash_image recovery recovery-RA-heroc-v1.6.2.img
After those commands, make sure it flashes successfully (It will return to the # sign). When I did mine, I kept getting the out of memory error. To fix this I simply unplugged the phone, and repeated my steps. Do not reboot the phone until the img successfully flashes.
After you get it successfully flashed, you will issue the following command
reboot recovery
That should take your into RA
I keep getting the out of memory error, too. I start the process over and over again, but no success. What I am noticing is that when I enter the cmd "adb remount" my phone disconnects from its sync with the pc. Should it be doing this? Also what will happen if I do reboot the phone? Any help would be appreciated.
