[Q] Xperia Play won't boot - doesn't even reach Sony Ericsson screen

Hey guys
After having a look at some custom roms for my Xperia Play R800i, I decided to try and install Cyanogenmod 9.0. After a long and stressful ordeal, I managed to root the device, install Clockworkmod Recovery, and flash the rom. I wasn't happy with this rom, so I flashed ICX. After being dissatisfied with this also, I decided to return to the stock rom, using Flashtool and Xperia_Play_Release_Generic_UK.ftf. When I went to update to Android 2.3.4 using the Sony Ericsson PC Companion software, it said that the phone contained modified software which could not be updated. Thinking this was an error, I re-flashed the ftf file, then tried to download the update through the Software Update option in the About Phone settings menu. The update seemed to be going fine, but soon after it began, the phone simply switched off. Now, when I press the power button, the phone vibrates, but does nothing else. It doesn't even get past the black screen. I viewed some similar problems on the Sony Ericsson support site, and they all advised use of the Update Service program. Once again, I was told that my phone contained modified software and therefor couldn't be updated. I also tried to flash the ftf again, but my phone is still as unresponsive as ever.
I imagine that the problem is to do with the software that is currently installed on the phone, and that it needs to be removed/replaced for me to switch it on. However, I can't know for sure because I can't switch it on.
Sorry for the long post, but I'm desperate to get my phone working again. Any and all suggestions would be useful. Thank you in advance

Ya... not supposed to FOTA on unlocked bootloader, it bricks you. As you've seen SEUS doesn't like locked bootloaders so the only way to use it again is to relock the bootloader. Unfortunately in order to do this you need to flash the relocker, which is a .ftf, which you can't do because your phone isn't recognized by flashtool. I dunno, you don't have a lot of options here, but lets lay them out:
1. Get into flash mode and recover via either a .ftf or use it to relock your bootloader so you can use SEUS
2. Get into fastboot and boot or flash a kernel or recovery. You could try flashing a CM7 kernel and installing its .zip
3. If nothing else works your only other option is to turn here:

This is what happens when you use official Sony update service with an unlocked bootloader.

Sorry to be a pain, but do you have a link to the specific .ftf I need to relock the bootloader?

Actually, ignore my last post. I Googled it and found the file quite easily. I flashed it with Flashtool and everything is working perfectly. Thank you so much for your help BuckM. You saved my phone

Here you go. I wouldn't bother relocking though. Just flash the ftf file that you want.
You will find them here.
Beaten too it by OP

d31b0ys right, you don't really NEED to relock your bootloader, its just an option to get SEUS working again. That being said keep in mind you can reunlock your bootloader again at any time using the same unlock code as before, just try to be a little more careful

did you try to pull out the battery then put it back, then hold the search buttion (wile the phone is still off) then put in the usb cable? if done correct your power buttion will turn blue. then download a stock .tft for your phone and flash with flashtool. this unbricked my phone

[Q] Stuck on logo, can't detect phone

Ok, first of all, I have been searching these forums and google all day, so please at least consider reading my question.
So today I decided to finally update my Xperia Arc S to Jelly Bean with CyanogenMod. I own this device for 2 years and all I have done hack-wise was rooting it.
And what the problem is? The update failed, and according to what I have read, this may have been caused due to insufficient internal memory. After that, my phone rebooted and it just can't boot now, it gets stuck with the Sony Ericsson logo.
I also have read that possible solutions were: Update with PCC, SEUS, Flash it with a Stock ROM, flash a stock kernel... And I CAN'T do any of these. PCC and SEUS just don't recognize my phone, SEUS doesn't even have Arc S on the list! The closest i have got to solving the problem was with flashtool, in which I got this happy message "15/044/2013 20:44:42 - ERROR - Error flashing. Aborted" over and over. Having read that this could be caused by the kernel, I tried flashing it instead. But after installing DroidSDK, I can't detect any devices using the "adb devices" command.
Any ideas? If I am just being stupid, I'm sorry, but I swear I searched a hell lot before posting this >_>

Even the repair option in PC Companion?

First - sorry for my english.
Second - try this:
Deattach battery from phone and connect the charge. LED must be green. Wait for ~10 min & then try to flash via Flashtool again and again. Please be patient. In some situations successful flashing might be on 5-6 flashing.

You have installed PcC,SEUS,good.Install gordon flash just in case(look for it on google)!Install flashtool on your pc,turn your Arc on(i know it's bootlooping,but try it can't hurt),run flashtool(just run it),connect your phone(it must be ON),and leave it for a while and see if flashtooo is recognizing your phone(if it does there will be some lines)!.-If this works continue!Download stock .ftf file for lt18i!
I suppose you know how to use flashtool?!.
Try that if that doesn't work SEUS will work and it has Arc and Arc S just look a bit,i know 'cause i have it.PcC won't work 'cause your phone isn't booting up,Well at least it never worked for me when i bricked my arc like this,but did work flashtool,always.I couldn't use SEUS 'cause of a bootloader unlocked.
Good luck,hope you'll fix it and next time,before flashing read the thread twice and follow the exacted steps,no jumping...
P.S for flashing JB you need to have ICS inatalled and i'think bootloader unlocked(not sure)...Cheers

[Q] Xperia Play R800AT stuck in bootloop. Please Help?

Hello, this is my first post with XDA, please forgive any poor grammar, spelling ect. Please assume I do have the proper drivers installed and downloaded the rom md5 check ect.
Like the title says my Xperia Play r800at is stuck in a boot loop. Trying to give you a picture of where I am right now ill put the list of events in order:
1 - Had an xperia play on stock for about a year. One day I get bored and successfully flashed XPLAY with flashtool, using the proper rom found on XDA.
2 - Subsequently, rooted Xplay using zerg rush (I believe it was) thing is, I'm pretty sure I left the boot loader untouched. Xplay continues to work fine for several weeks until.
*Here's where things start to fall apart!*
3 - Xplay begins to experience "snowy" screen, indicative of bad flex cable, had to replace that leaving the device was out of commission for a couple weeks.
4 - Flex cable arrives, I replace it . Upon first startup snowy screen problem is gone, however Xplay refuses to boot past the first "Sony Ericsson" startup (screen goes black and repeats - hence boot loop).
5 - I read on other forums that re-flashing the rom has worked for other people experiencing this issue. I tried installing the same firware rom that last worked - still bootloop. I tired the default firmware rom from SE - still bootloop.
6 - Tried using the Sony Companion Repair tool. At first it wouldn't do work coming back with "cannnot find software for this device error". Assuming that its because I'm rooted and possibly unlocked the bootloader somehow, making the sony repair tool not play nice.
7 - I ran the "Xperia_Relock_bootloader.ftf Application (found on xda) which seemed to relock the bootloader (or something). Then after that I tried to re-flashed a rom - still boot loop.
8 - But after doing that Sony Companion finally does recognize my phone and allows me to repair the device. Which is supposed to fix boot loop error... but not for me
At this point I'm all out of ideas and direction. Anyone help please??

I also have a R800at, when you unlock the bootloader it pretty much becomes at R800i. There is only one thing I can think of is "R800i_4.0.1.A.0.283_ReFlash" which is apparently supposed to unbrick your device you can download it here http://forum.xda-developers.com/showthread.php?p=42229855#post42229855 I've never used it but I always keep it saved just in case.
You should definitely unlock your bootloader again before trying this. Then you should flash an unlocked vendor frimware, either R800i_4.0.2.A.0.62_phoenixvendor or R800_4.0.2.A.0.79 after you flash the "reflash" frimware.

HELP ME PLEASE ! Bricked but Fastboot mode and flash mode working.

Hello everyone here, im a noob around these parts but hope that this beautiful community might help me.
So heres the deal, my gf got an xperia m, that outta the blue started acting out, what i mean for this is, rebooting, outta nowhere and eventually a couple of days later it died.
Making my investigations to get to the problem and therefore the solution, she stated that putting it on the SUS or SONY Pc Companion didn't help at all, plus keep getting error 0x0000067 or 0x000007d5 on PC Companion.
After seeing this, she says tried to unlock the bootloader to install a CWM 6.0 for the 15.4.A.1.9 software, wich it had running, didnt got through since the moment she enter the command through fastboot to check the bootloader status throgh the command fastboot flashing get_unlock_ability but no response just stuck on three dots.
Also tried to flash through FLASHTOOL installing the drivers and everything as ive done with other decives checking everything is okay, which they are, since ive succefully recovered an brick C1904 using CWM with a previous Backup, but the tool gets stuck on flashing loader and wont give a percentage.
Tried Flashing remotely the CWM.img to the boot, but it wont flash, always failed, as for specifics about the code, If really needed ill post them on the next reply.
Hope Someone can Help me,
Regards Jmaquilon

Which error are you getting while flashing the recovery? is it something like remote command not allowed ? If it is then try to flash the recovery in the boot partition (I have done the same many time cuz there are some problem s with my current kernel)and what happens is instead of system the recovery boots up ..
If this doesnt works then try xperiafirm it may bring your phone back to life!
Hope it helps!

Just flash stock rom using flashtool software. Download the Stock Sony Xperia M Rom here http://forum.xda-developers.com/showthread.php?t=2699085 and flash it using flash mode in flashtool. Good Luck

Have I mangled my poor phone?

Hey all,
Haven't touched this phone in years, but was inspired to pick it up again yesterday. I can't for the life of me remember all the crap I did to it back in the day, but there was some "minimal" thing installed to it that made it play PS games better or something, and there was some LuPuS wolf thingy that came up when it booted.
Half the stuff I tried to do within the phone was crashing, so in my infinite wisdom I decided, "Hey! Why not just flash back to stock firmware!?"
And so the genius that I am, attempted to do just that.
So I found Flashtool and a nice stock rom and pretty much it did something, but then eventually fails every time as "Failed to verify sin header" and aborts the flash.
Now the phone is stuck in a loop, either the Sony Ericsson logo comes up, then a exclamation point in a triangle, or it goes into Flash mode.
I've tried several different stock roms:
R800i_4.0.2.A.0.58_Enhanced
R800i_4.0.2.A.0.62
And I've tried several versions of Flashtool:
flashtool_0.9.24.4
flashtool-0.6.8.0-windows
flashtool-0.9.11.0-windows
But no combination of any of those gets me past the error during flash.
I also tried the Xperia Companion, but it only complains my phone is locked and won't let me do anything. Of course it's not locked, and I can't even unlock it because it doesn't boot into anything.
I also tried the SEUS but it crashes upon launch (Windows 10).
Anything else I can do? Or is this phone toast?
Thank you in advance!
EDIT:
Alright, time for some extra silliness... and maybe I just don't understand what I'm reading here. So the sticker on the phone under the battery reports R800x, indicating the Verizon version.
The old Flashtool actually let me flash a stock Verizon ftf on there, but then it returns to the looping between Sony Ericsson/Exclamation point and Flash mode.
I ran the 9.24.4 version of Flashtool and attempted the same Verizon stock ftf. And here's what it said....
Current device : R800i
Also, the newer versions of Flashtool report this:
Bootloader status : UNROOTABLE
But the older copy of Flashtool reports I'm rooted.
I did try to get SUS working on another PC, but has same issues, seems to crash/die reaching out to a server that no longer exists.
EDIT 2:
Woohoo! Fixed! Continued to research all the info out there, and seems I just had to relock bootloader.
