[Q] XPERIA Play won't start, shows flash mode evertime connected with USB

Hello,
my XPERIA Play is broken and I don't knwo how to fix it.
I've first unlocked the bootloader and then flashed Cyanogenmod 7.1 on it.
But the vibration doesn't have any function and so i flashed with flashtool the stock firmware witch I found in this forum. After that I've started OTA Updater and my phone shutted down. Now it won't start anymore, it vibrates shortly and if you hold the power button longer, it vibrates in dinstances.
When I connect the XPERIA with my computer (Windows 7) the green lights shining and my pc says that it's in flash mode. I can't change to Fastboot Mode.
I've flashed more than once firmwares on the phone, everything I've done couldn't fixe it..
Can anybody help me?

Well you can't get OTA updates when your bootloader is unlocked.Unfortunately I can't help much about the problems with the flash mode since I've never encountered such a problem.So sorry about that.
EDIT:When you try to update Via OTA your phone would surely get bricked because once your bootloader's unlocked SE doesn't consider your phone as warranted and certificates within the phone gets wiped because that would enable flashing 3rd party firmwares and kernels.
Sorry if I'm making this complicated.

I've relocked the bootloader, that wasn't the problem.
I could fix it with flashtool, I only had to flash the bootloader form the developer section and now everything works fine. I can also update with SEUS again (tested from 2.3.3 to 2.3.5)

Hi everyone.
This is my problem:
I recently updated my arc s, from.42 to .62(idiot) and after that the phone wont switch on, when I try to switch it on it only shows a green blink from side and that is it.
I have tried to flash it with generic rom, with SEUS update, nothing works, it just says flashing complete turn on the phone but I CAN NOT DO THAT!!!
When I connect it with the computer it is in flash mode (SEMC Flash Drive), bootloader is locked!!!
What can I do???:crying::crying::crying:

Try SEUS again. That will be your best option.

Go to a Sony Support Center?

Try it again, if it fails try flashtool. If that fails contact Sony

[Q] Xperia Arc won't boot after CWM crash

I am new at all this stuff but i think I'm starting to somehow get a hang of it. I rooted my phone this week running .587 by downgrading the kernel etc, you know. Today I wanted to try another rom so I followed this guide: http://forum.xda-developers.com/showthread.php?t=1955248 To install Xperia Ultimate HD on my phone with a locked bootloader.
However during step 8 CWM shut down and started to boot. But it doesn't start and I'm unable to get back into CWM My computer won't recognise the phone so I can't flash the kernel or do a complete reset using SUS. What do I do? is it save:able?

Been doing flashtool ftf recoveries whenever this occured. Do not power on arc s with it stuck. let flashtool self boot to flash mode and you will be back in buisness again.

if you could tell me what to do a bit more precise I'd really love you! like a small guide

I assumed you have flashtool since you mention about kernel downgrade. if no get it installed
the step actually same as flashing the kernel with phone power off.
reference link to a online guide

4. format /system

ok first since ur stuck flash back to stock using flash tools n then follow the procedure.. i had a similar problem n i fixed it.. it was a very simple prob.. for installing these custom roms u ve to format system/ , so if ur using the cwm app by pvyparts ul loose the cwm after wiping it.. all u ve to do is after flashing the custom rom ul ve to install CWM back (use cwm version 5 available in the thread by pvyparts.. not the latest one..)
here's the thread for CWM
n post back if it works..

Thanks guys, really appreciate it, will try these methods out.

Still won't work
I tried doing all the different things you said but the phone won't boot holding in the back button and inserting the datacable. The light on the side turns green but nothing else happens.

Mate, press the back button while you connect to PC and flashtool will show "device connected in flashmode" than select a firmware to FLASH and FLASH it. After the process is done disconnect and power it on... =)

Yeah, that I know and that's what I'm doing. When I hold down the back key and connect to the pc all that happens is that the green led lights up. Flashtool won't recognise it and it still says that I should hold down the back key and then connect to the PC...

I was also stuck at Sony logo and it reboots every time just after sony logo. Then i used flashtool, flashed using "LT15i_4.1.B.0.587_Kernel.ftf".....
Now it boot further, but only to XPERIA logo, and then reboots....but certain times i have seen it getting past the logo, like it shows a display asking for pc companion, even the taskbar too with time and blutooth icon on it....but all of a sudden it reboots. i have tried rebooting more than a 100 times, while taking out battery everytime.
Also, I'm not able to get into recovery mode. I tried this using the combination of power on, and when sony logo appears, pressing and releasing volume down repeatedly. I hope i'm doing right.
So what should I do?? am not able to use this phone for a week...
Please help me out.
Ok got it working. I just unlocked the boot loader from sony bootloader site(sorry couldn't post the link, because of low post count)
So, it booted up but show error as soon as put a sim, that "Unfortunately keypad has stopped working".
I figured out the culprit, it is the build version with i flash it. I reflashed it with LT15i_4.1.B.0.431_kernel.ftf, now it working fine like a charm.
So much relief...!!
Hope this may help someone too...so i shared!!!

Z1C won't stay in flashmode

Ok so I've been trying to get flashtool to work with my xperia z1c but I can't get the phone to stay in flashmode. The green led lights briefly and flashtool detects a device in flashmode but after a short time it just drops out of flashmode and boots normally. I originally blamed windows 8.1 but have tried 2 windows 7 machines with the same results. Have tried the Sony z1c drivers package and the latest flashtool drivers - same result. I've searched on Google and found people with the same problem on different xperia devices but has anyone else had the same problem with their z1c? if so has anyone solved it?

So what is the problem? If the phone does not stay long enough in flashmode, try this:
Open flashtool
Click flash, and set up everything (firmware, wipe, etc.)
Now click on flash
After 30 seconds plug in your phone in flashmode.

Happened to me too. I just flashed it before it rebooted, once it starts flashing it wont reboot it'll finish the process. So no worries everything worked out fine.

Thanks for the responses. I'd previously tried to flash an ftf by putting the phone into flashmode first then pressing flash and it always rebooted before the files were prepared so assumed there was something wrong. If you prepare the files first then put the phone into flashmode then all is okay. Thanks again.

how do you boot into flashmode?
the right way is: turn off your device, open flashtools, choose flashmode, choose your ftf you want to flash and wait until finished,
push Vol- and hold it, then plug your device via usb to the computer, then flashtool does its job...
