[Q] Xperia Tablet Z cannot get into Flashmode or Fastboot?? HELP
I'm not one to normally start new threads that already have similar posts but I personally cannot seem to find a solution. So heres my scenario:
I have a Sony Xperia Tablet Z SGP311 that I got right after launch. I flashed a custom rom, yada, yada, you know the deal. However, I flashed back to the stock rom and updated it to the latest sony firmware and was running that for the past month. Everything was going good until BAM, my tablet turns off. I thought it had died since I had been watching a video but I remembered it was at 96% when I started using it so I turned it back on and got the screen of the wrench and screwdriver and it would freeze and bootloop. I then used flashtool to flash back to 10.1.C.0.370 and it worked fine, i got it into flashmode and it flashed properly and the tablet worked for a few hours until BAM, back to the wrench and screwdriver bootloop. SO this time i flashed back to the same firmware and used companion to update it to the latest software and that failed and my tablet fails to boot. Not only that I cannot even get it to go into flash mode and here is what happens with various button combos:
Power Button - nothing
Power + volume up - white flash, then triple white flash
If i do power and volume up until the white flash and then move my finger to volume down the LED turns green but only if plugged in, however it doesn't put it into flashmode like it should.
Green light stays on after unplugging.
Red charge light comes on only after hours of being on the charger.
I've tried booting into flashmode, fastboot, just boot on, nothing works even though the LED's are doing SOMETHING. I havent changed what flasthool i've been using and the drivers were working before. I've tried restarting my computer, using different cables, different USB ports.
I am puzzeled on what i should do and wonder if my tablet is bricked, however, I heard that if the white LED comes on and flashes that something can be done about it, but i have no clue on where to go next.
ANY HELP WOULD BE GREATLY APPRECIATED THANKS!!
