hello
share ko lang po konti ka alaman ko about common problems nang motorola
phones since wala pa ako masyado nakita thread about this matter
Dead no power
First make sure your battery is 100% ok and charger
If you cant seem to get it to power even with a external power supply
Wont go to boot mode by pressing (hold and press +and# then power button)
No responds with charger
1.Try to boot phone by pressing (hold and press +and# then power
button) if its goes to boot mode try to flash phone if not step 2
2.Try to connect phone to smart-moto and check if phone is in flash mode already thats why it wont turn on
3.Reheat PA module or remove it and try to turn phone on without PA .
if PA is shorted phone wont turn on or no responds at all with any
power supply ( some shorted PA cannot be tested by a tester in battery
terminal so I recommend that you take PA out , base on my experience )
Additional info
Phone turns on then goes off rite away even with a charger
Phone only turn on with a charger plug in
Phone chargers but drains rite away
