Hey guys
could you help me out? Ive searched through these forums as much as i can but i cant seem to get a solid answer or fix to my problem, so lemme explain
through PDAnet i managed to get a driver for my phone "YunOS ACB Interface"
HOWEVER when i turn off the phone it is not read by my pc at all, it just charges,
now i read through and i figured maybe my pc doesnt have a mtk65xx preloader driver so i took out the abttery and plugged the phone back in, and now it came up with teh mtk65xx preloader in the device manager, however when i used the USB VCOM MTK677 driver pack and installed the drivers, my phone would just connect and disconnect every half a second or second, so thats wehre i am at currently, drivers are working when phone is on but when i turn it off with battery nothing happens to show pc has phone, exept charging,
when i take battery out and plug it in, phone connects and disconnects all the time Sad

please help me out
thanks

You might want to mention what it as you're trying to do. Flash a ROM... Or?

oh yeah

well im currently on lewa which i loaded via CWM after trying to flash the miui beta, im thinking my preloader wasnt working with the miui? not sure, however i shud add i flashed 1.04 via sp flash tools on my old laptop before, and it was tricky getting the drivers to work, however through some luck i got it to work but sadly i cant remember how,
but for the purpose of this post i need the connection to my pc so that i can flash 1.08 onto my phone with sp flash tools
thanks again

The issue may be the preloader. You can try different preloader from ROM you jnow as work in the past.

Also, you shouldn't need both sets of drivers (PDAnet and the other ones you installed). You might want to try to uninstall all drivers and start fresh.

Did you look through the common SP Flash Tool Problem sticky?

yeah tahnks for the advice,
yeah i have tried starting afresh, but i guess il give it another go

cant hurt
and yep am hoping that by flashing a new preloader i can get miui on my phone to work, am currentl running lewa 1.04 i installed via cwm with the update.zip found on this forum

man thanks
and yes i have read through the sp flash tool problem but my problem isnt in the flash tool, i can hear my phone connecting and disconnecting all the time when i have turned it off and preloader driver "attempted" to be installed i think? not sure
but will try dleeting all the drivers again

it hink it worked last time, but i tried it already but as you know, cant hurt

if you have windows 8 or 8.1 you might consider that it didnt install the drivers correctly. so you should enable the authorization of installing digitally unsigned drivers and then try to reinstall them.

its a short procedure requiring a restart. im sayin this because it didnt get the drivers for me also so i had to do it manually but you cant install unsigned drivers (microsoft ... really if someone wants to do stuff to their pc lettem...)
i hope you wont have problems after this.
cheers.

i hated how windows took so much power away from the user in wndows 8 so i just downgraded, and that took me like a whole day coz of their stupid thing wehre u cant downgrade even through a bootdisk.
buuut im on windows 7 now and have been using windows 7 for a while since i got this phone, so its not a problem with windows "8" as im on 7 currently, but thanks for the info maybe itl help someone else

If your phone don't show any options when you plug the usb cable I have the solution for you. I had this problem until yesterday and now its fine

**CrownSA** · 2014-04-02, 01:42

could you share it? I personally dont have this problem but someone else who might happen to read this post might

but thanks for the help anyway, it shows all four options to me(that what your talkinga bout right? the USB storage, Media device, Camera, USB charge only )
thanks anyways
