I bought S4 phone, but i have problem with it.
it has very old firmware -
Android 4.0.4, but main issue is hboot - version 1.14.0002, radio 1.06es.50.02.31
i can't make s-off, i can't even flash RUU - my RUU is [email protected]#p://androidruu.com/getdownload.php?file=Ville/RUU_Ville_U_JB_45_S_HTC_Europe_3.16.401.8_Radio_1. 11.50.05.28_10.27.50.08L_release_301814_signed_2_4 .exe but if i try to flash it, i see message "invalid signature".
I can flash only my native RUU - [email protected]$p://androidruu.com/getdownload.php?file=Ville/RUU_Ville_U_ICS_40_S_HTC_Europe_2.31.401.5_Radio_1 .06es.50.02.31_10.09a.50.04L_release_275655_signed .exe
i can only get root with kingo, but s-off is a problem - moonshine fails to do it (10 attempts then message "don't drink and shine" and bricked phone. Recovering possible only flasing native RUU
Please help me, i bought S4 phone only for custom ROM's but now i must use very old stock, flashing official update is impossible.
OTA is available, but when downloading finishes, i see message "archive is damaged". I tried to do this 3 timesm but it fails.
