I'm the owner of a Moto G 8GB retail.DE xt1032. And i can't install custom Roms.
The phone shipped with good ol' 4.3, and then I flashed the retail.DE 4.4.2 OTA as soon as it came out. But I got tired so I, unlocked bootloader, installed CWM and installed a custom ROM (at the time, CM11, wich I loved).
Then I tried to change the bootanimation (I know, such a lame thing to do) and i wasn't able to boot a custom ROM anymore, even stock based (infusion).
I tried every rom available (cm11, PA, Carbon, AOSP/CodeAurora, Nexus G), and it ALWAYS hangs on bootanimation forever.
If I remember correctly, I had to downgrade to 4.3 Bootloader at that time to install CMW, but since I've had this problem I already reverted to Retail.DE Stock and upgraded via OTA to stock 4.4.2 (so bootloader should have been upgraded to 4.4 too...?).
I still have the 4.3 bootloader .img file on my computer, so should I flash it and try again?
