Hi, I am having serious problems with my R800at, someday it reboots and now it shows me the Sony Ericsson logo like 2 seconds and reboots again. I've trying with wotan and flashtool but when I connect the phone pressing the back key the cellphone only powers on and reboots like I said before. When I try to connect the phone in flashmode I only hear the "Usb disconnect" sound again and again. I already try with another battery and no luck. Maybe someone can help me.

I tried a regular update via the normal procedure with Sony PC companion.
This however stopped responding during the update, so the phone got bricked with only the sony logo during boot up.
Due to the build in battery I waited till it ran out of power so I could try to flash it by Flashtool or SUS.
After connecting the USB cable it charge with orange led. After about 10 to 15 min. of charging the sony logo comes up.
I tried holding the down the volume button right after connecting the USB till the sony logo appears, but nothing happened.
It just won't enter Flashmode. Trying the volume up with powerbutton I can enter Fastboot mode.
But the phone was in original state during the update(no unlocked bootloader or Root).
Can somebody help me with this nice phone, just bought a few days ago:crying:
Any developer?
the sony logo shouldnt appear when you are trying to do flashmode or fastboot.
maybe youre doing it wrong. try again.

Thx for your reply.I guess I wasn't clear enough. After the failed update all I get is the Sony logo.
The phone got bricked by the failed update. I need to drain the battery in order to turn off the phone.
Now I'm trying to get the phone into flashmode in order to flash the firmware with flashtool. But
no success yet!
The problem is that I can't get into the flashmode by holding down the volume key. But the Fastboot mode can be activated.
Pls mind that the bootloader has been untouched, therefore locked.
So anybody got a solution?
Update
I finally managed to get the phone into Flashmode. Thx to Cognosco
But now I got another problem. I tried to flash a couple of firmwares with Flashtool.
But it all got stuck at 23%. Do I flashed with the wrong procedure or firmware?
I tried flashing older fw LT26ii_4.0.4_DE_6.1.A.2.45.ftf and a new fw LT26ii_4.0.4_6.1.A.2.55_Arabic.ftf.
Also SEUS fail in restoring/updating the phone after recognizing it in Flashmode.
What more can I try? Is the phone really dead?
Update 2
I tried different Exclusion in Flashtool. I noticed only system can't be flashed.
Since the device broke down from firmware 6.1.A.250 to 6.1.A.250 maybe I need the generic fw of 250?
I searched but couldn't find this firmware for the SL. If anybody has this fw for the Xperia SL LT26ii, pls share with me.
Update 3
I even tried to flash with Sony's own system EMMA. This got the same installation issue. Guess the phone really got bricked hard and unrecoverable.
since you can enter flashmode, try to update it with pc companion again.
just make sure you've charged your phone and you're on locked bootloader.
I tried many times to flash again with PC companion and SUS, but ends with same results. I get an installation error. The phone can only be charged for about ten minutes then the phone turns on and discharge itself. This cycle continues. I can enter Flashmode before the Logo comes up, but the phone won't charge in Flashmode.
I've been searching through the forums for a while now and I've not found a fault like mine unless I've just completely missed it but I have an xperia play now when I got it, I was told it was dead but when I connected the usb cable it lit up with the amber light and when I press the power button I get a short vibrate but nothing more. Nothing comes on screen and the sony PC companion keeps popping up telling me that my xperia play is connected and it continues to do so every 10 seconds or so until I disconnect it, the sound it makes when a usb device is connected and disconnected can get rather annoying after a while.
I tried reflashing it but that didn't work, I flashed it most recently with R800_4.0.2.A.0.79.ftf and before that with Xperia Play_Release_Generic UK.ftf but nothing seems to change it, at first I thought it could be hardware that was failing like the screen had died but that wouldn't explain it connecting and disconnecting from the laptop every 10 seconds or so and also in the past 2-3 weeks that I've been messing around with it, I've had the screen come on twice but I can't replicate what happened to make it work, it just seemed to come on randomly, I have however managed to kill it the same way each time by sliding the phone open and pressing the power button to lock screen, each time I pressed it with the phone slid up, it killed it back to no screen coming on and it connecting and disconnecting.
I can enter fastboot and tried to flash a kernel but it told me the phone needed to be rooted to do so and I can't find a guide telling me how to root it without having to change settings on the phone, which I can't do.
If anyone has had this problem before or can help it would be much appreciated.
Thanks
Is it flashtool telling you that you need to be rooted? If so then your bootloader isn't unlocked.

Yeah flashtool is telling me that when I'm trying to flash a new kernel. I assumed that the bootloader needed to be unlocked to enter fastboot? or that's at least what I've read while searching for a solution. Can it be unlocked without having to do anything on the phone?
Hey, guys I need some help here. Please, I need it so bad.
I bought my Xperia Z1 Compact about a month ago, and today when I was updating my apps suddenly it turned off. Then, I turn it on again but it keeps restarting after it showed the Sony Logo. As same that it did when I tried to charge it plus the red LED blinking. So I decided to hard restart it using the PC Companion through the update software menu. After following the instructions, I turned on my phone and it keeps restarting after showing the Sony Logo. I did the hard restart using PC companion several times. But, it keeps restarting after showing the Sony Logo.
And now, when I press the power button, it only vibrate and not showing anything on the screen. When I tried to charge it, the red LED keeps blinking over.
I need your help, I don;t know what I must do now. So please, help me.

If you didn't unlock the bootloader and if you didn't root it, just take it back, as you still have a warranty... You'll get new one...
Use flashtool to download the official ROM for your model and if you want to, region. Follow its instructions to flash the ROM. To enter flash mode, hold power+vol up until it vibrates for 3 times to shut it off and when flashtool instructs you to turn it on, hold vol down and connect the USB cable.

Hello,
I have a problem with Sony Xperia Acro S.
I want to get into Android menu!
Mention that the phone is booted, appears Sony logo, then Xperia, Sony wallpaper, then restarts.
I tried many combinations of keys to enter. But none worked.
Can you tell me one that works?
I tried with Flashtool program and Sony PC..., but the phone starts charging and disconnects Flashtool. I reset the button, but still did not go.
So what is the key combination?
thank you

I believe you have a battery issue here. Need to change the battery. You can find one at aliexpress. I myself had the same problem. Changing the battery solved the problem. Youtube video for disassembling the Xperia ZL
