[Q] Xperia T stuck at device encryption failed

Hello everyone!
My Xperia T LT30P is stuck at "device encrytion failed please reset" everytime I turn it on. The "Reset Device" button on this screen doesn't do anything when tapped.
I tried to flash 7.0.A-Global firmware via Flashtool but it always gets stuck here at 0%:
21/009/2013 12:09:46 - INFO - Loader : S1_Root_7054 - Version : R5F001 / Bootloader status : ROOTABLE
Is there anything else I should try?
Thanks a lot for reading.

flash a latest version of JB,
or better yet, install PCCompanion (Just google it) and repair your phone that way

did you try Phone Repair option in PC Companion?

Thanks for your replies.
I have also tried LT30p_9.1.A.1.140_CE_Skyfall.ftf but same result. I have also tried different versions of flashtool.
PC Companion can't detect my phone. I have tried 2 different computers and each one is stuck on install MTP drivers. I guess unless the drivers are installed, PC companion won't detect it.
I have also tried connecting the phone in flash mode but PC companion asks to restart the phone in normal mode.

run the driver.exe file in the flashtool installation folder.
choose fastboot, flashmode and tx drivers
try again with pccompanion

PC companion still can't detect the phone. I have installed/re-installed all the drivers you mentioned.
As Flashtool isn't able to flash the .ftf firmware to the phone, is there any other firmware available that can be flashed via fastboot?

No.
Try downloading Sony's EMMA program and repairing with that

Thanks for your suggestion.
Seems like EMMA only works with unlocked bootloaders. And my Xperia T can't be unlocked as USB debugging is off and there is no way I can turn it back on.
Further help needed, please.

Please help to unbrick my xperia z

I am in an awkward situation.
xperia z, 4.2.2 244 rooted stock rom, bootloader locked, usb debug mode off, recovery not installed.
I accidentally corrupted build.prop and the phone bricked.
I cannot use flashtool to flash the stock rom back because usb debug mode is off.
I cannot use Sony update service Pro to force update because it said that "your phone already has the latest available software installed".
I cannot use PC Companion to repair because the software said that "Sony update engine doesn't have software available for your phone".
Please help.

You can use Flashtool to flash stock rom, doesn't matter if usb debug mode is on or off (only needed to install recovery or to root)
Download stock rom, install flashtool + drivers and follow screen instructions.. Good Luck! :good:

J have the same problem, yesterday j installed cyanogenmod, now xperia Z was on SONY logo and j can't flash original firmware on flashtool, j can only flash original kernel, but is still on sony logo
SUS says that hasn't new firmware for my phone.
What can j do ????
Thanks in advance

Just follow the flashtool instruction and re-flash the stock rom first, everything will return to unroot stated. Reroot then and try again.

If you still can enter custom recovery, you only need flash rom and (with) suitable kernel.
If not, you need Flashtool.
- make sure you have the newest version of flashtool and driver
- connect your phone to pc.
- when computer show error about usb not recognized, go to computer management - device manager. Find something in universal serial bus controller list that have yellow triangle and exclamation mark. right click and remove it
- disconnect your phone then reboot your pc
- install flashtool and driver, reboot pc again
- connect your phone to pc. Now, it should detect your phone.
- do flashing procedure

How about flashtool drivers, have you install it yet? If your phone can get flashmode or fastboot mode, flashtool should detect your phone, unless you did it the wrong way.

Flashtool does detect my phone and when it gets disconnected. It is when I hit on the flash icon and go to where directory for ftf is that it will not recongize any ftf files anywhere. I have heard similar problems with same issue but havent seen a solution except maybe the ftf file i have is corrupted

Xperia SP almost dead after flashing. Need help.

I flashed my Xperia SP with from Jellybeam to CM13 rom. I didn't create any backup, wiped clean everything including cache using twrp recovery. While the setup installed CM13 without any error but I downloaded the wrong gapps and the setup didn't accept those. So I chose to reboot the cell and since then it just stopped responding. Although it is showing the green led while plugged in via USB, it won't start in neither fastboot nor recovery mode.
I'm stuck here and have no idea what to do.
I tried installing PC companion, flashtools, SP flashtools, emma, everything. None of these detect my cell. I'm using Windows 10 (64 bit) and am at a dead end.
Any help would be appreciated.

UPDATE:
I managed to flash it with errors and now it's stuck in a SONY logo bootloop. Its starts, shows SONY logo for a while and then turns off again. Again it's not getting recognised by any flash tool, sony companion etc.
Help please.

Whether I try to flash it or unlock, phone boots up before the process is completed. I'm completely stumped here.

Hi! Still have the problem? I faced the same two days ago when I tried to change the on on my SP. But finally I could save the Phone by searching a bit on the net. Pls tell me if matter is still on and I try to translate the steps to english.

Hey!
Sad to hear, but maybe (I hope) this method will help you. Basically what you will get is an original Xperia SP with 4.1 android as it came from the factory.
You will need:
1. Sony Mobile Flasher by Androxyde" version 0.9.18.6. Don't know if newer version came or better. You can find it here in forums. http://forum.xda-developers.com/showthread.php?t=2489955
2. The basic ROM "12.0.A.2.254".
The method that helped me:
SP turned off. Cable not connected.
Start Sony Mobile Flasher (Flashtool) , give administrator rights.
Top left cornet click on the bolt and choose flashmode, then in firmware selector you can find and select the downloaded ROMs and kernels. Choose the official 4.1 (12.0.A.2.254). Click falsh so it starts to proceed.
Then a windows appears called "wait for flashmode".
Now. Grab your turned off SP press volume down and connect the usb to pc. Keep holding volume down button till flashtool starts to upload the system. (Hopefully it will be fast enough, and phone will not turn on. For me it was)
After flashtool is finished you will see:
09:50:53 - INFO - Flashing finished.
09:50:53 - INFO - Please unplug and start your phone
09:50:53 - INFO - For flashtool, Unknown Sources and Debugging must be checked in phone settings
09:50:54 - INFO - Device connected in flash mode
Unplug and start the SP
If everything went as planned you have your phone back with stock 4.1 and 12.0.A.2.254 kernel.

Thanks a lot brother. At first it didn't work when I flashed it with the latest version of Flasher. Then I installed the exact version you mentioned (0.9.18.6) and phone didn't boot during the flashing and now it's back to normal with the default 4.1 stock.
Thanks a bunch, you're a life saver for me. :highfive:

OK, so I'm gonna assume that you have at least a working recovery. Here's a possible solution: Have you tried flashing a stock based custom ROM (e.g: Kryptonian, MX Rom or DStrikers Z1 Kai)? Then, from there you can flash a pure stock via flashtool.

guys, this was mentioned a couple times already, best way is to download Emma from Sony and flash the official software. Then you can flash a kernel via fastboot again and all should work. This is due to Nougat is corrupting the apps log partition which is not in use there, but is required for stock Lollipop. I did that a couple times and all worked fine...

Ok, i will try the mxrom and than, but i tried that already and do i need first to lock my bootloader and then flash stock, emma didnt recognice my phone same as flashtool and one thing more, i tried to flash kernel sin from ftf via fastboot bud it says image is not boot image and says fail. I tried on win 10 same to do win recognizes phone as somc bit flashtool doesnt recognize phone.
