s4 exynos loading problem
hi = lately the s4 has come up with a problem i can't quite identfy - when running download or recovery i get error - e:unable to load /efs (invalid argument) =
no matter which method which rom, phone stops 4 or 5 notes before the end of the samsung tune/logo .
can't find the needed bootloader to see if it helps, the one i found gave me signature errors and missing "magic string"
does anyone have a lead on the appropriate bootloader (doesnt matter odin or recovery)
have z3x box but it also reports, samsung modem not found and it cannot read the phone at all, i tried flashing with it but it gave the same results as flashing with odin.
I also read that there is a kitkat 4.4.2 version that although supposedly for the i9500 it corrupts SOME seems this version is for indian 9500 not europe 9500 - so now
i am stuck -PLEASE ANYONE WITH THE RIGHT SOLUTION/ANSWER/DOWNLOAD
any answer will be much much appreciated
