Problem: iTunes Only nang Dumating sa akin.
1st Action Taken [Basic Muna wag tayo Deretso Hardware]
Reformat via itunes but sad to say "Error 21"
2nd Action Taken =Disassemble the unit and check all the parts. maynakita akong Kunting coroded resistors gaya ng sa picture below. Nilinis ko at Restore Ulit
Result = Negative! Same "Error 21"
3rd Action Taken = Disassemble again i check the back part of the Board.. Malinis Naman, Nagabaka sakali nalng ako sa C135_RF na Palitan. check the picture Below
Result = Positive, Nadali sa Chamba!
After Removing C135_RF Restore ko ulit, only Board Battery and charging connector, At hindi ako nabigo, na Restore na sya.
