update :

tried factory reset, wipe data from Recovery, no signal

reflashed the phone with Acer_DLTool_V3.006 + BIN_Acer_AV051_S500_RV10RC04_EMEA_ORGROD, no signal , no matter the sim card inside, nor the phone was locked or unlocked (this time entered the code to unlock it).

downgraded to 4.0.4 with : SDs_Acer_S500_AV043.RV00RC00_AV043.RV20RC01_EMEA_ORGROD, no signal , no matter the sim card inside, nor the phone was locked or unlocked (this time entered the code to unlock it)

tried to flash it with WW_GEN, but bootloader is locked and phone is CPU "1" (checked with fastboot)

a friend of mine said that after unlocking, some security area may be damaged (like EFS on Samsung)

any ideea ?

thanks

Have you tried to solve it in the the network settings? Go to 'more' beneath data usage, and then 'mobile networks'. Switch the network mode between 2g and 3g and experiment with the settings in 'network operator'.

If that fails too, send it in to Acer for repair, the warranty should cover it.

tried different settings on network, but no result. someone said it is a boot area fault/problem, and it can be done.

any ideea ?

Yes, send it to Acer after reflashing stock ROM declaring "no signal", no one there will really check the reason of the defect and will change the mainboard... ;-)

kinda complicated with warranty...

someone said may be a software problem after unlocking, boot area could be affected.

any ideea how to reflash boot area ?

thanks
