1pl/spl Goof

[dobbiedoo]

I didnt completely read the instructions and upgraded my radio rom with 2.22.11, now no gsm. I am trying to downgrade back to Radio rom 1.09.10, my battery icon is stuck in a charging mode and I cannot sync the phone to reflash any ideas on how to procede. Thanks

Are you already SIM/CID unlocked?

Upgrade to an official carrier ROM to get IPL/SPL 2.x and you'll be free to use the 2.x radio ROMs.

The 2.x radios are generally better than the 1.x radios so there's little reason not to update to the 2.x IPL/SPL.
