Hello. I have just received a 2nd hand htc a8181 pb99200. This wont turn on eccept with the power plugged in, and only then i can get to a hboot screen. At first i thought it could be a dodgey OS. So i downloaded and tried to install. Shipped ROMs and the ROM: RUU_Desire_C_Verizon_WWE_2.36.605.1_release_signed_with_driver.exe when this runs i get to a screen that says: ERROR : LOW MAIN BATTERY POWER The battery power is less than 30%. Please recharge the battery, then try the ROM update utitlity again. Does this showe that the battery needs replacing? Also when the phone came it had no microSD card. Is this needed? or is this a operating system fault? Thanks.
