No network after installing CM7 on Xperia Arc After successfully installing CM7 on Xperia arc by following the steps here, my phone doesn't pick up any network. I looked through the forums and see that some people have reported the same problem. I downloaded the stable image from CM home page for Xperia arc. 

After scouring through xda-developer forums I came across this new ROM for arc, does it solve the problem? http://forum.xda-developers.com/showthread.php?t=1310313

Also found these in the forums, http://forum.xda-developers.com/showthread.php?t=1102523&amp;page=127#1263 which essentially says,


Use flashtool to flash baseband_36 (.tft)
Use fastboot to flash cm7 custom kernel (boot.img)
Use recovery to flash the rom (wipe cache &amp; factory reset then flash the rom)
Start your phone and go to apps menu
chose "Dev tools" -> Bad Behavior -> Crash the system server -> reboot


I am using linux and couldn't make sense of the first step to flash the file.

Any help on solving this problem would be very helpful.
A "baseband" would generally refer to modem firmware.

It seems like the first step is to modify the modem firmware so CM7 can use it.

Does this flashtool have a linux binary? (This tool seems to be unique to SE phones, I didn't have to use flashtool to modify HTC phones, only fastboot.)

Found Flashtool. XDA link | Source Code Repository
