I did some tricks (like I did before on XT1033->XT1032 variant) and it worked like a charm!!! I'm uploading at this time a flashable zip. I'll post instructions after upload.There's some screenshots attached.[]'sInstallation steps:1) Flash RETUAWS_XT1064_4.4.4_KXB21.85-17_cid9_CFC without flashing fsg.mbn (if you're on another firmware, you'll get errors on install process)Important: Do not flash fsg.mbn or you will have NO SIGNAL after installation and need to flash XT1068/XT1069 fsg.mbn back after the process to get signal back.2) Install custom recovery (CWM, TWRP, etc...)3) Download and install update_nofsg.zip via recovery.4) Wipe cache/data.5) If you doesn't get any error message at install process, reboot and wait... (it's around 5 minutes first startup)update-nofsg-working.zip - https://drive.google.com/open?id=0B3...eG8&authuser=0 (I bring back this file because someone said to me that this is working and sent to me screenshots.)Problems with file permissions. When I get home, I'll fix this.Magically it's working again. =OBuglist:1) no sim selector activity, you need to select a single sim for voice calls (I'm working on this)Working receive calls from both SIMs
