when you get into bootloader you have to hit the power button once to get into fastboot mode. try all in one toolkit run the command follow the on screen instructions if it says waiting for device hit the power button once and it should start

did you press power button once
I encountered a similar issue when I tried to flash a new rom. I have 2 computers, one with Windows 8 and the other with Windows 7. I found that I couldn't get adb working on the Win8 PC but it worked nicely on the win7.
You should also make sure your USB Cable is good and not plugged into any USB Hub or USB 3.0 plug
Best to plugin to the motherboard directly. I learned this the hard way one day with a USB Hub. Nothing worked till i unhooked the Hub from the PC
I have no problems in windows 8 now

It's easy to fix Just follow my steps. :fingers-crossed:
1.Prepare the rom which was running ok before,for example, for me it was @satanduck 's prerooted TWRP S124 rom.
2.Open the SP flash tool.
3.Load the scatter file from the rom which worked ok for you.
4.Tick the box that says 'DA DL All With Check Sum'
5.Hit Firmware Upgrade
Now is the hardest step
1.Open the cover of your phone.
2.Look for the red reset button which was close to SD card and press it a few times.
3.Connect USB cable to your phone and firmware upgrade should start and wait for the green circle! :good::laugh:
Best luck :good:

Yes, I installed mtk usb drivers. but I´m not sure if it´s ok o no. Because I have to connect the battery and push volume+up button to make it connected. and it´ll disappear immediately in device management window.

Hi,
Please verify that you have a correct production date. I got a P780 after 0314. please try the solution on this post
http://forum.xda-developers.com/showpost.php?p=52665841&postcount=16
If this resolves your problem, that keep that preloader. With that you can almost flash every rom that there is with the flashtool.
(i'm very satisfied with the latest rom on needrom Vibeui2.0 (the rom page also offers the new preloader )
Greetz,
btw to try to flash with the new preloader set up the flashtool, push the red button on the back of your phone, connect the phone an release the button. If all the drivers are correct your phone will be flashed. ( this new batch phones gave me a heart attack also , mine wasn't even 12 hours active before i softbricked it )

When I push the red button, phone can not be recognized by computer. Only I press the volume-up button, it can be recognized by computer.
I start the flash, then push volume-up button to make it connected, but then got BROM error. I attach the screen picture.

You must have this FlashTool - SP_Flash_Tool_v3.1304.0.119. Not Optional.
Check if your phone is produced in 2014. If it is you must use another preloader.

Orrrr.. your phone could be a clone. Just an ideea ...
Could you tell us more about your phone... maybe pictures taken from battery or box who came with ?
I am trying to unlock my bootbloader but I can't seem to get my phone to boot into fastboot. I have tried the official method posted through the Sony Developer site and It says to Hold the power button + Volume down at the same time and plug it into your computer. And when I do this, a blue light should come on notifying me that I'm in fastboot mode. But no matter how much I try this, my phone simply just changes its state to charging. Can someone please help me out?

Hello i wanted to root and unlock my SM-T220 and did all of that and then tried to remove the warning by overwriting up_param from termux
That resulted in bootlooping with only backlight on
Then i tried recovering using MTK SP Flash but now it only shows up as MTK usb device cant even get to bootloader, is the tablet toast?
Can you boot it to EDL?
You shouldn't have done it with Termux anyways since it was fully booted from the beginning.

Does the screen come on at all when you power it up?
If it does, put it in download mode:
Power device off completely with no cables connected
Hold both Volume buttons, do not press Power, connect USB cable from PC
Device should start in download mode
Reflash firmware using Odin
