Update rom from jiayu bbs site, fixes the bluetooth audio problem for calling with carkit(garbled audio).

install via clockwork mod best to wipe data/cache/dalvik out front.

select zip from sd and install.

keep in mind that recovery will be replaced by stock one, but easy to put back with jiayu.es app.

replaced chinese calendar with google calendar (it was unusable unless your chinese).

      Not sure yet, I'm on my first battery charge.

      I'm at 65% after 11 hours.

      I must say that I had this problem also with all the roms I tried before but I will post the first results as soon as its drained.

    is it possible to install greek language ?

    It is possible but loads of work to implement in the Rom itself, as is there is no Greek language in this stock Rom. I suggest you install aan app called morelocale. This will translate it for you and is in Google play store.

    The other way is described on xda Forum.

      This bug is resolved in the latest Rom version.

      Jiayu brought out an update for all the g4 versions.

      Did you try the latest Rom for your type yet.

      It includes new drivers witch solved the issue for me.

      This Rom is for advanced version.

      All other version updates are here:

      Just make sure you use one of the October 2013 roms.

      I came across this on the bbs site of jiayu, it said somewhere that in the Rom new drivers were included.

      It is a Chinese site but Google translate works just fine in this case.

      It said; actualization hardware drivers.

    Goodmorning, I loaded this ROM yesterday. It works just fine, but now my internal memory went back from 32 Gig to 2,5 gig. Does anyone have a clue?

      How did you flash? Used clockwork mod? Wiped data/cache/dalvik?

      Maybe wipe internal memory.

      Solved it for some people on gizchina.

      Through settings/storage/Erase phone storage

      Hallo Andries,

      Ik heb hetzelfde probleem. Heb jij het nog weten op te lossen?

      Bij voorbaat dank voor antwoord.

      Groeten Lars

    I flashed my device with SPflash. That worked just fine. The option of erasing the memory will not work. The internal memory is just 2,4 Gb instead off 32 Gb. It looks like the internal memory is gone. Any other sugestions?
