Hello !
Having been given a dead MP4+Camera IPOD like Anyka AK3223 based.
But it looks it is DEAD, ...really DEAD ?
Even after full charge it is unresponsive, nothing on the screen, no sound
I tried everything that is shown in the forum (Thanks to Sableroku for his SUPER POST on the bios access and firmware update for this model)
but nothing happens....
...I even tried the short cut of D0...D8 pins on the memory
ops:
So now I start to wonder whether the previous owner has done some special upgrade to it:
- seems some chips are no longer on the board
- the battery (a LiPo i guess...3.7v...?) is curiously installed with full connection to the power but with a zener diode in between... :shock:
- when I full charge, the battery shows sometimes 3.78....or even 3.88v...or up to 4v and above :roll:
- i cannot get anything on the memory Vcc when connected to the USB (4.98v)...but there's something under 1v when connected to a USB charger (5.16v)
- in other words it is not too much alive
Could someone help me out ?
- I would need a picture of the board as it is supposed to be (near the battery...in particular)
- any other hints of what might be checked to see if it is all dead
THANKS VERY MUCH !!!!!
