Hi,
I've read all the posts regarding this kind of topic but with no luck for me.
The problem started few days ago, when my phone asked me for a restart because no sim card detected. OK, let's do it - I said. After that the phone can't start anymore, the green light appeared and the SONY title was on the screen but the start process stopped at this time, and was no reaction for anything. At this point the ON/OFF button was not helped to switch off also. I had to take out the battery for a retry.
I've tried to repair the phone software with the PC Companion software. The upgrade process was completed succesfully, but after that the problem still exist, the phone cannot start, I leave it for 10 mins, because the PC Companion said that the first start maybe longer, but I think the 10mins should be enough. So no luck with this try but it cleared to me that the phone can access the FLASHMODE with the "back" button and USB plug.
After that I tried to get some information with Sony EMMA. The EMMA said that the phone is recognized but the bootloader is locked, so I visited the recommended site unlockbootloader.sonymobile.com. I followed the recommendations, the Android Studio and Google driver were installed well, with the updated android_winusb.inf, but after that I can't start the phone on FASTBOOT mode. The fastboot devices command did not detected the phone. I can't see the blue light, I've tried it with all of the buttons+USB plug.
My last try was a 3rd party tool, Flashtool. It recognized the phone and entered it to FLASHMODE but can't unlock the bootloader, as the product said, it will not working on the official way.
One more comment, the phone can charge the battery, if I plug the USB cable, I can see the red light if the battery low, I can see the battery icon filling in the screen and see the green light when it's charged.
What can I do anymore for start the phone?
