Marshall Stanmore 2 (flash chip)

[thuygsm]

hello
in my case, the Bluetooth - AUX - RCA signal light goes off after 5 seconds and repeats, (sound is there then 5 seconds then gone and repeats)

i forgot them and reconnected, but they do not play on the speaker, although i can still adjust the 3 modes Bluetooth - AUX - RCA (on the phone)

after i loaded a new rom, i lost bluetooth connection and could not power off, no boot sound. i loaded the previously saved rom again, but the situation still cannot find bluetooth and boot sound
hope everyone can help
