I managed to get this work outside the US. I (re)flashed all the original sprint radio config partitions (modemst1, modemst2, radio, rfg_0, rfg_1, rfg_2, rfg_3, rfg_4 and rfg_8, so not just the ones is some firmware update) after conversion, and everything is working fine.

How Is possible ?

You have to download a firmware.zip file from here (small file, not the full rom), then flash it using fasboot flash zip firmware.zip and then flash the 1.x rom.
explanation is in the FAQ in the first comment.
