phone type:<br />TYPE 1101201-BV K A BAB<br />01W13 KRC 114 1231/179 R6C

Hi!<br />You have bad PA. Replace it with another one.

This is a partial scan of the PCB of my old dead T28 (the back side). The PCB of an R320 looks very similarly.

If your phone is completely dead (i.e. does not even communicate) and consumes too high current from the battery, then probably the power amplifier (P.A.) is damaged.

You may turn it on after you desolder the marked resistor, but the phone will not register to the network without problems and it will be impossible to make calls from it.

To repair such phone, replace the P.A. using hot-air soldering station.

Hi ed2k_1!

This is not my solution, but I know it works.<br />I do not know where to buy good PAs, I've never repaired a phone by changing the PA.

I have the same problem with R310s. Phone find network and than said No Access. Flashing didn't<br />help. Probabblly P.A.?

[giggelito]

try a full flash, then use a dead phone fix software.

Atr 5.3

whatn flash allways have full charge batteri.. or els you get failur n error in phones..

hello m8s

if ur making manual search & then the result is no access , for sure the problem is in the pa .
