[Xperia Play Q&A, Help & Troubleshooting] doolfly:
Hi,

My Xperia Play r800a is now dead after testpoint unlock. ( Testpoint unlock looks successful. Logs attached. )

It does not boot, although I can feel vibration after pressing the power button. I tried to charge it. Seems not a battery problem.

The phone was previously rooted by Zergrush. Android version 2.3.4 ...... 0.42.

The phone was carrier locked by Telstra.

-------Update ------

*#*#7378423#*#* Service info > Configuration > Rooting Status > Bootloader unlock allowed Said NO

I think my problem was 'It was NO'. I should not use Testpoint to unlock it.

Now

I succesfully used Flashtool 0.70 to flash a R800a_3.0.1.A.0.145_Telcel. It is a Android 2.3.3 firmware. From Mexican Telcel?

It is strange that it could recognize my Telstra SIM card for the first time ( I didn't make a call). After swithing to Virginmobile, it show still locked to network. Then I switch back to the Telstra SIM card. It shows NO SIM card......

I am charging it now. Will try to flash other ROM.

OK. I flushed the R800a_4.0.2.A.0.42_North America.tft and the phone is back to life. It is the same version as original Telstra one.

The network and the Bootloader are still locked.

Thanks to the WIKI from XDA.

------------------------

Please help. If there is any way to recovery it? Is it worth to try Testpoint method again?

Shall I try Sony Customer Service?
