Hey Ein69, welcome to AF! While I understand your desire to get an answer, and that there is a lack of activity in your device's forum, The Lounge is for non-Android discussion, and clearly your question is on-topic. I have moved your thread into your device forum, however (and I can't make any guarantees) I will make a request to my fellow staff to see if we can get you some help. Regardless, thanks for signing up!

 

One thing I've found by a web search that might be worth a try (I don't know this phone either): pull the battery out to shut the phone down. Reinsert, then press and hold the power button and volume up for at least 8-12 seconds. That's supposed to get you into recovery. If it does, then we have a starting point. If it gets you into a custom recovery then we should be able get the phone back one way or another, even if at the worst it involves wiping and reinstalling.

Did you manage to make the backup, or did it just go like this when you selected the backup option? I'm afraid I have a real mistrust of ROM Manager - I'm sure it works fine on some devices, but there are also too many where it just doesn't.

In case it's useful I found that hint about getting into recovery from post number 10 of this XDA thread.

 

To me, it sounds like you don't have a recovery installed. Go into ROM manager and go to the settings and check the option to erase recovery before flashing. Then go back to the main screen and flash clockwork a couple times.

I'm definitely not an expert on your phone, there may also be a manual way to flash a recovery file.

 

I was able to root my Prism and put a custom rom on it as well. The XDA link that Hadron posted is very helpful.

 

After rooting my prism I decided to clear up some internal memory space by moving my system apps to my SD card manually by using root file explorer. After I copied and pasted into my SD card I deleted the apps off the internal memory. Well that didn’t work to well for me.... my phone started having pop-up windows saying error. I turned it off and tried to reboot it but it is stuck in a loop now. I can't turn it on to recovery mode because of mod manager app. PLEASE HELP ME!!!!!!

 

I'm on Android 2.3.3 and am using the dark tremors apps to SD
I'm rooted and have CWR flashed
Check out the dt a2sd over at xD a forum if you can't find it let me know ....I have the script to flash in recovery.... the app for it you can find on market.
