How can I go back after flashing an unsuccessful file with no backups in HTC EVO 3D GSM?
Simply flash any compatible GSM ROM to your phone (look for one on xda-developers forums) via recovery console after performing another round of wipe. Whatever incompatible drivers and radios were introduced by the CDMA version will be overwritten, and the phone should boot successfully. After that you can continue searching for the ROM with full Arabic support.
