R800i Not sure what's happened (explanation inside) - Xperia Play Q&A, Help & Troubleshooting

Hi, Just thought I'd try a little modding GAH.
First things first, Stock R800i no simlocks etc.
Rooted via super one click, fine.
Thought I'd unlock the boot loader, no problem.
Try a doomlord kernel, install went fine, wifi working no problem.
But then I hit a problem, you can connect the phone to the PC and the PC installs the drivers fine but it won't let me access the storage, not even an autoplay message.
The second more serious issue is I have no lock screen (slide to unlock part).
So I thought I'd try flashing it back to stock using flashtool but for some reason it wants an S1 Download driver, no matter how much searching I cannot find the right file.
Sorry if this seems a bit noobish, thanks for your time

try these usb drivers...I think they are the ones you need

Thanks for trying but that didn't work either

Just a quick update, found the right drivers (had them the whole time) but I didn't force the installation.
FFFUUU
Sorry for panicking

Hi Cokker,
Could you explain more precisely for me how you solved this problem, plz?
I have the same problems (no screenlock, no notification SD card connect...) when trying connect my XPlay to PC. The fact is, this happen after I hard-reset my Xplay to the factory default data (in Settings) >.<
For more infos: I've rooted my Xplay with zergRush methode, also unlocked bootloaders.
Thanks very much.

[Q] Bootloop after unlocking Bootloader

EDIT: Alright I solved it. I had to install Gordon's Gate. Those were the correct drivers, the ones I had were not. You can get the drivers from Flash Tool, in the drivers folder.
Alright guys of xda, I've spent the last six hours trying to fix this myself but I just can not do it with my knowledge of the Xperia Play. I wanted to ask this in the dev section but you know I can't post there until I post ten times in here. Instead of spamming the forums I'll just ask here.
Starting off, I have an R800i model bought off Ebay brand new. I love the phone, though it has no warranty so if I can't fix this I'm out $410. It was 2.3.3 prior to this mess.
I used this guide to unlock the bootloader. Yes it is confirmed to be unlocked as I tried it again and it said that it was already unlocked. I proceeded to follow step 2 and flashed the play_modded.img to my Xperia Play. After that I unplugged the USB and tried turning the phone on. To my expectations, I was stuck in a bootloop.
I looked around and tried flashing stock ROMS via Flash Tool 3.0 and 2.9.1 Beta. Both said I must go and turn on Debugging through the Android System. The system I don't have on the phone.
I tried to flash stock ROMS with fastboot, though they are ftf files, which I am not familiar with. The prompt said that the files were too big.
Another method I tried was the clockwork recovery mod that is booted from fastboot. I tried recovering a stock NANDROID backup that Logseman posted right here but it freezes at the Sony Ericsson splash screen.
I have downloaded at least two gigs trying to fix this in the last six hours to no avail. So I don't know what to do. I'm sorry for posting this in the wrong section, I just don't have an option and this is my last day off this week. I need to fix it today. I'll be on the forums refreshing this thread for the next twelve hours or until I get the fixed. So I will be here and responding instantly.
Actually, you've posted this in the right section
1) Download Flashtool 0.2.9.1 (you have done it already, I guess). 0.3.0.0 DOESN'T WORK with Xperia Play.
2) Download the 4.0.A.368 FTF file and put it in the "firmwares" folder of the Flashtool folder (if you haven't done so already).
3) Switch off the phone.
4) Fire up Flashtool. Click on "Flash" and choose the 4.0.A386 ROM
5) Obey the on-screen instructions about connecting your phone.
Once it's finished, you don't have to do anything more save booting your phone and using it. Ignore those "switch on USB debugging and Unknown sources".
I tried that and this is what I get.
Then.try.again. There is only one way to use Flashtool, and it's the one I've described.

I've never got any errors with flashtool, although some people don't seem to be able to use it
Trying again and again and again would never have worked. Brute force never does. I looked through the forums outside of the Xperia Play and I found a thread explaining how it was the drivers. I installed Gordon's Gate and it worked flawlessly the first time I tried, just as you described it.
It's not.about.brute force. It's about preparing the computer properly...

Well trying again and again isn't preparing the computer properly is it?
Either way your method did work and I greatly appreciate it. Thank you for the help.

[Q] Lost USB connection after SE bootloader unlock

After searching the forums i still havent found a solution.
The problem is i decided to unlock the bootloader using Sony on my Arc S a day ago.
Now when i connect the USB it will not connect to the MSC or MTP though the computer pings and sony companion comes up but says the usual reboot etc.
I have tried all the different combinations of turning USB debug and other things on and off but to no avail.
Has anyone else had this problems and fixed it?
Try reinstalling PC companion with the option in phone connection.
sinkster©
Sorry to say thats not working :s
Any idea if factory reset may work? Holding off doing that cos hate having to put everything back on lol
Factory reset did not work
Any thought on my next options would be appreciated?
Can i still install a different ROM to the memory card? I have no recovery so i dont know if i can do much of anything?
Thanks for any help.
How did you unlock your bootloader
Sent from my LT18i using Tapatalk 2
is your camera and home button not functioning too ? reflash back using flashtool or if it doesn't work, use wotanserver..
I now have it running after using Wotanserver twice :s
The only problem now is it wont root (Bootloader is still unloacked, did it via Sony)?
I tried Doomlord but it says read only as it tries to do it.
I dont know how to use flashtools as for some reason it wont install on my computer (possible Kasperski stopping this).
How do you reinstall the ADB drivers cos i think that may be the problem.
Try the link at this post
Managed to get flash tools installed and that rooted it
It now wont update OTA so wondered if sony companion will update but will flash tools root after?
Lots of thanks to everyone for there help seems i have question after question lol.
Just when i think i know what i'm doing i get another phone and it starts again. Sticking with sony now though even if they dont have Gorrilla glass
you can't update via Sony Companion / OTA because you have unlocked bootloader..

[Q] R800i completely bricked?

Hello dear readers and great XDA members,
Last summer I unlocked the bootloader of my Xperia Play R800i with the testpoint method. Everything worked fine: I installed CWM and loaded a FreeXperia version of CyanogenMod 9.1.
A couple of days ago, I wanted to finally update my ROM to a newer version since there had been so many releases since last summer. I loaded the new ROM and everything worked fine. However, some of the problems I hoped would've been solved by the update, weren't solved at all, especially the video capturing and panorama pictures. So I decided it maybe would be better to flash a new kernel.
I searched for a kernel, but couldn't find anything I liked. Then, I can't remember where, someone posted the "boot.img" files included in the FreeXperia CM9 ROM zip packages were kernel releases. So I decided to use flashtool and flash the boot.img as a new kernel.
This obviously didn't work and I tried some others. By the way: I couldn't boot into ClockWorkMod anymore since I tried to flash a new kernel. Only fastboot and flashmode would work.
I couldn't remember which kernel I used last summer, so I wandered the internet and eventually found that an X10 kernel was included in Flashtool. I though I remembered something about X10 from last summer, so I decided to stupidly flash that kernel to my Xperia Play.
After this flash completed, my phone doesn't respond to anything anymore. Following a list of things I tried (everytime after I tried something, I removed the USB cable and the battery to make sure the Xperia Play was turned off):
- When I press and hold the power button, nothing happens, not even the small vibrate always felt when the phone starts.
- Getting into fastboot mode doesn't work anymore (I tried with holding the search button and connecting USB, as well as some other buttons, nothing worked.)
- Getting into flashmode doesn't work either.
- No matter what I do, the phone won't give me a sign it's still alive. (no LED, no vibrate, no screen, nothing.)
- I tried the Sony Update Service, but that obviously doesn't recognize the phone
- Flashtool doesn't recognize the phone either.
- ADB doesn't recognize the phone of course.
- s1tool (the tool I used for the TestPoint bootloader unlock) recognizes I plug something in, but then gives an error it can't get access to it.
- I charged the battery overnight and tried all of the above again... still nothing works...
- When I plug in the phone to the PC, my PC recognizes something plugged in, but with the name QHSUSB_DLOAD in Device Manager.
(by the way: I am using Windows 8 Pro x64)
Is this phone completely dead or is there any way it can be saved? I was planning on keeping this phone at least until the end of 2013 or begin of 2014 before upgrading... An immediate upgrade is not in my budget and for now I have returned to my Nokia 5530 on Symbian, but that's nothing compared to Android :'(
Thank you very much in advance... I really hope someone can save my poor phone. I know I have been stupid, but I think I somehow panicked when I couldn't get the phone back into CWM and stupidly flashed the X10... Stupid stupid me.
Well I always update to the latest working kernel when I flash a new rom. The one working currently for me is fxp152 kernel.
Have you tried with battery, holding the search button, plug it in, then hold the Power button while still holding search.
Contact Alejandrissimo, he can probably help you.

Thank you for the response! Where do you find these kernels? Are those boot.img files included with fxp zip files the kernel images?
I hadn't tried to hold the power button after holding search button + plugging it in, but it doesn't work either
I will probably contact Alejandrissimo in a couple of days if I can't solve it myself or if nobody else can help me solve it...
Thank you!

Hi Tommy,
I am very sorry for my late response. I haven't fixed my phone yet, but I fear only a hardware flash would work... I think I am going to try to get my phone back to the store where I bought it and I hope they'll fix it. If they don't, I will try to find someone who can hardware flash or ask Allejandrissimo (an Xperia bricked devices expert, it seems...)
I hope you will get your phone to work again! (And please let me know how you did it if you succeed). I will keep you updated if there is any progress. I am very busy at the moment though, so I don't know when I can get my phone back to the store. In the meantime, I have also bought a used Galaxy Nexus...
Greetings,
Sven
EDIT: I think I also accidentally flashed the X10 rom or kernel in the flashtool...
Could be easily fixed by flashtool, tried the same (flashing x10) and phone looked dead. The I toke the battery out and placed it back. Then I could enter flashmode and flash a stock ftf.

Maybe you still have a chance! Bcoz I think you have completely damaged ta files+ semcboot which can only be repaired by se toolbox 3 which requires credits(money)( I m assuming it'll detect phone bcoz s1 tool recognized it with error ) if you have it than you can repair it or you can contact alejandressimo on gtalk.

Hello Arbiterandrea,
I am very sorry tot report that I wasn't able to fix my Xperia Play. I sent my phone back to the online store I bought it from and it arrived there 1 day before my guarantee expired. When I got my phone back, it was a brand new one with a different serial number, no screen protector, not a scratch. And it was for free thanks to my guarantee, even though I bricked it myself. (I just told them "it suddenly stopped working")
If you've got any guarantee left, you could try that, but if I understand correctly you already tried that... Then I think you should contact Allejandrissimo, I've heard many good things about him. I didn't contact him myself, though.
Good luck! And let me know if you have fixed it?

With what did you try to upgrade and how? It seems your update has gone wrong, as you state, it got terminated in the middle? Probably if you connect through fastboot, or flashtool for windows, you can put in a new kernel and the rom. It seems your phones kernel is broken too. It should be fine once you install a new kernel and rom.
For how to do that please look at one of the tutorials here: http://forum.xda-developers.com/showthread.php?t=2320872
Hope it'll work out for you.

Sony Ericsson Play R800AT Boot loop.

So, here's the deal with this phone. It's sat untouched for many many years. The original owner can't remember why she got rid of it (family friend). So I volunteered to take it, and turn it into an emulator device. However, it was made clear as to why she got rid of it. The phone is stuck in a gnarly boot loop. The boot loop is, Sony Ericsson screen lit up, and then goes to an unlit version of the logo. After a while, the phone will restart repeat. The phone will get into flash mode (green light) and will not continue the loop but stays on the unlit version of Sony Ericcson. I've gotten it into fastboot once, maybe twice, but I can't remember exactly how I did it (holding menu doesn't work)
I have installed the drivers for the phone, however, the phone is listed as:
E:\
Device Type: Portal Device
Manufacturer: SEMC
Location: on Volume
The drivers that it is apparently using is wpdfs.inf
Things I have tried to correct this issue.
-The Xperia app (tells me to enter flashmode in its own way and never does anything after)
-Flashing using "FlashTool"
It sees a phone but just says.
"19/025/2018 22:25:46 - INFO - Device connected with USB debugging off
19/025/2018 22:25:46 - INFO - For 2011 devices line, be sure you are not in MTP mode"
I've attempted using a fastboot method but nothing substantial as fastboot rarely happens.
Accessing the device through ADB (ADB shows not devices connected
Accessing the device through FastBoot (FastBoot shows "waiting for devices")
I have crawled through dozens of pages worth of information, similar questions, similar problems and come up short. Any advice would be super helpful.
Will provide images, and further information if requested. Thanks for your time.
I'm not familiar with the at version. Also maybe its already stated in the post and I miss it, did u try flashmode on flashtools and flash stock TFT?this is the first thing you wanna do in case of problems. For fastboot if I remember correctly you have to push search button and not the menu button, but I haven't my xplay with me.

Hey, I did try flashing the stock firmware, the version is the AT&T version from the US. The problem with attempting to flash is Flashtool doesn't detect the phone. It sees that there's a phone plugged in, but flashing is impossible because it can't find the phone. I figured it must've been a driver issue, so I scoured the web to find drivers but only could find the 800a drivers, so I went ahead and attempted those, but not to no avail.
My next attempt to bring out Windows 7 and attempt to install the drivers on Windows 7, instead of 10. Just been a bit slow, and feeling a bit dejected on the whole project.

to install flashtools drivers in win 10 you need to disable uac but maybe you already did that. make sure the adb drivers are fully and correctly installe. have you tried flashing a kernel in fastboot mode by pushing the search button? also i would try to install r800i or r800a drivers. then i would suggest to make a little bit of search (i know you already did a lot...) to ensure that you can flash r800i or r800a firmware on your r800at and also try that route. i´m sorry i can´t help you more but i´m in europe and never worked on a r800at..
Hey, dont worry about it. This post is basically a hail mary for a phone that super old. I haven't tried flashing in fast boot because I have only ever gotten in fast boot once or twice. Fast boot is menu key correct? Cause I see conflict information all over the place.
i´m pretty sure it´s the search button for fastboot mode
Do you need a new battery?
Hi Disenfranchised,
I recently got out my old r800i GSM which was regularly being flung across the lounge by my kids, attached a charging cable and I had exactly the same boot loop issues as yours, but only as long as the phone was being charged. I ended up biting the bullet and buying a new battery and the phone started up. I ended up flashing Gin2Kat and it has been working well other than occasionally reverting back to the same behaviour for about an hour if the battery was completely discharged. The funny thing is when i finally manage to boot the phone at the right point during the boot loop cycle, the battery is only at 2%, meaning during the boot loop the battery is charging for maybe only a fraction of the on-off cycle.
It's a bit of an outlay (my battery was about GBP £10 - ebay). I now play SNES games on this every day during my commute. There are a few quibbles - the audio out port doesn't work (bluetooth audio works) and I get a wifi error but I ended up using Gin2Kat's apk installer to install my apps from micro-sd.
Anyway, it's a bit of a risk but see how it goes.
