HELP ME KEEP MY PHOTO ALIVE

<< < (2/2)

killer:
this happened to my friends ipod photo (No Rockbox installed) as well before, we've tried plugging it on high powered usb port and wall charger, nothing happened.. what i did was open the ipod and charge the battery using a li-ion charger seperately, and it worked!.

tdtooke:
I could be wrong, but I think plugging it into a power source that is not the computer will fix this.  I remember on my old mini after I updated the firmware I had to plug it into the charger (not the computer).  A little progress bar would fill up then it'd be done and you're set.  

killer:
yes that is right, normally after upgrading on latest iPod firmware (apple OS) using itunes or ipodservice, it would ask you to use a wall charger afterward, perhaps upgrading firmware requires more power than what the battery would provide.

scharkalvin:
If you are using an USB wall charger NOT made specifically for the ipod you might have a problem because the iPod looks for a specific termination of the data lines to know that it is connected to a wall charger capable of the required current.

I built my own charger and tied each data line high to 5v with a 75 kohm 1% resistor, and also tied low with a 49.9 kohm resistor (well I actually used two 100 kohm 1% resistors in parallel).  This specific termination on each data line tells the ipod that it may draw 500ma from the power supply.

This data came from Apple documentation.
