[Q] wich revision of usb charging unit
Hi there, a friend of mine had an issue with is s4 i9505, the battery won't charge anymore so he bring the phone where it bought and they replace the chargin unit board. After 3 months the unit catch fires while chargin. The phone works, it turns on and with the "burned" charging unit it charges but only via pc usb.
I have read online that many i9505 only charges with pc usb and not anymore from original charger. Anyone knows why?
I want to replace the chargin board but, there are 2 version of it: rev 19 and rev 25. What are the differences? On ebay i read that you have to replace the unit with the same revision, it's true? Should rev 25 be the new one and maybe solve bugs from the 19? This i9505 has the 19 version but it has been replaced and i don't know wich is the original one
can someone answer my questions? Thank you
