Hi all , i have a RAZR M xt907 running stock JB 4.1.2 , ROOTED and BOOTLOADER UNLOCKED , and TWRP Recovery ,22.214.171.124 , official KitKat upgrade is available but i am unable to upgrade due to motorola services issue (on checking for upgrade , system requires motorola services account and gives a server connection failure ultimately , i have done many factory resets and all is useless , it is a common problem though).
Is There anyway to upgrade manually to stock kitkat from PC (via RSD) or something like that ?
OR can i install a KitKat Custom Rom with my present configuration ? Please guide me ,
Thanks in Advance ,
