I cant upgrade my radio rom..

[kinesis]

I put Olipro on the phone before upgrading the RADIO.

I heard this is the incorrect way to do it, and locks you out of upgrading your radio.

I want to put 3.45 on my phone, the reception is awful and it takes like 15 mins for it to locate a cell tower once the phone boots. Even if it wont fix that, id feel better knowing i have the most recent radio

I tried to update to 3.45.x rom using RUU and it gets to 8% then says Invalid Command error.

So if i need to put the stock boot loader back on the phone, what do i do?

Also will I lose my current WinMo?
