Guest nbkappa Posted May 21, 2013 Report Share Posted May 21, 2013 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 Link to comment Share on other sites More sharing options...
Guest BrtH Posted May 22, 2013 Report Share Posted May 22, 2013 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.
