saving current ROM

---

Recently rooted my MT3G. I have used Root Checker to verify root access and BusyBox install.

I have ROM manager installed. I believe, I should first save the original ROM, in case I need to restore it. When I use the menu item to save current ROM, it goes to the myTouch green splash screen, then to the black screen with the triangle containing an !

At that point do I need to press a combination of keys to get into next step, or just wait? It does not seem to do anything at that point.

To add to this, in Rom Manager I first flashed the ClockworkMod Recovery. However, when I click the menu to "Reboot into Recovery", I get the green myTouch start screen and it just hangs there.

Just do a nand backup in custom recovery (clockwork, amon ra, whichever one you're using; power down the phone then press and hold HOME+POWER until you get to it), it'll save it to your sd card.

Sounds like recovery didn't install correctly. Try reinstalling recovery and see if that helps. You could try installing recovery from terminal emulator. If you don't have term emulator search for it in the market then follow directions here.
This method will work for clockwork also just replace the file/file name with it.

OK, I power down. Then do home+power until green myTouch screen appears, continue to hold down home+power until triangle with ! appears, then release buttons, repress home+power and it goes to original MT3G recovery. So, sounds like Clockwork recovery did not install. Will try terminal emulator install method.

OK, when I run this in terminal I get

flash_image: not found

Found something online that says flash_image is not available in HTC stock rom. I am currently running FROYO, not a custom rom.

Obtained a copy of flash_image, will put it in and try again

I have flash_image on the SD card, but can not move it to /system/bin, not even by using the terminal. : (

I wonder if the app Root Explorer could move it or copy/paste it.

How in the heck does anyone install new roms in an MT3G if you can not flash???
