Hi,

I purchased LG Optimus M from Metro few days ago. It comes with preinstalled Android 2.2.1.

I tried to root, and downgrade phone to 2.2 but unsuccessfully:
1. z4root app doesn't work with 2.2.1.
2. SuperOneClick doesn't work with 2.2.1.
3. LGNPST downgrade to 2.2 (MS690ZV3_36.S3_36.P3014.tot, MS690ZV3_36.scr, MPC_AWS_3014.prl) make phone screen black.
4. After LGNPST update (rootable 2.2.1) with MS690ZV4_26-root.BIN, MS690ZV3_36.scr, MPC_AWS_3014.prl phone no longer connects to the network.

Any ideas what else can I try?

Thanks
