[Q] Xperia Play cannot boot after trying to update

Help my xperia play cannot boot anymore after trying to update to 2.3.4 (from 2.3.2). It is rooted (though I am not sure whether bootloader is unlocked most probably it isn't). When it was updating, I accidentally pressed the power button and it switched off. The next moment, I found myself with a bricked phone that just vibrates when I pressed the power button. I tried flashing the rom in already but the situation still persists. Can anyone help?

Well, you don't mention which model of the Play you have. If you aren't sure, you can remove the battery and look on the sticker. It will say something like "R800x" or "R800i", etc.
Once you know what this is, you can reflash the original firmware. This will put the phone back to the original, unrooted stock version, just like it just came out of the box. Most of the firmwares needed are found in this post right here. The firmware file is usually archived either with rar or zip, so you will need to unarchive it. You will also need to download and install Flashtool which can be found here. In the event you can't access the file from there, a mirror link is found here.
Once you have the necessary files, it's pretty easy to do. There are complete instructions on the Flashtool site, but basically you just copy the ftf file into the firmwares folder within the Flashtool folder. Then launch Flashtool and follow the on screen instructions.
Post back with results or questions. And please hit the Thanks button if I helped you.

Nothing
It is still the same.

My Play is r800i by the way

Special ftf file?
I heard that I must use a special ftf file to unbrick my phone. Any ideas? Thanks

I think its from here: http://forum.xda-developers.com/showthread.php?t=1126354

But then the links are not working (I think)

from my noob knowledge if you ota with bootloader unlocked then you will brick the device but in your 1st post you said you aint sure if its locked or unlocked. then in your second last post you tried to download the FOTAunbrick.exe file but you said the download link is unavailable. download FOTAunbrick.exe and run it (the link isn't dead just downloaded it myself for safe keeping) or xperia_relock_bootloader.ftf(2nd option) i have below. you got nothing to lose.
ps
next time you wanna upgrade just use wontan server(not free) or download an ftf. and flash it via flashtool here with the same instructions dude in the second post has given regarding flashtool steps

The link there is dead in some countries, like the US, as it is MultiUpload. @Solomon4400 - I suggest posting that file up to another site that sonyxperiaplayer can access to download it.
@ sonyxperiaplayer - you actually downloaded the ftf and the flashtool program I linked you to? Because normally that ought to do it.

I agree with netizenmt on this one.
the special ftf files you are seeking is the stock rom firmware he already managed.
As you got r800i, you have to flash the international stock firmware (I guess but I am not sure!) you could also just flash stock rom 2.3.4 - So you can upgrage while saving your phone - instead of re-applieing 2.3.2
Just get flashtool and firmware (ftf file) connect phone to pc, put ftf file in flashtool, follow instructions. Good to go

Flashing Error with Flashtool

I was trying to flash my Xperia PLAY with Flashtool v0.8.5.0 but this error keeps coming up:
Code:
ERROR - ERR_SEVERITY="MAJOR";ERR_CLASS="SECURITY_CLASS";"ERR_DYNAMIC="SIN header verification failed"
Any ideas how to fix this error?
EDIT: I know what caused this error, it was because I accidentally selected the X10 FTF that Flashtool comes with when you install it.

Possibly the wrong FTF for your device, double check you have the correct one for your model

It's the correct one, I've used it before and it worked.
Probably got corrupted or something, I'm re-downloading it again and I'll see if it works.

When I load the FTF in Flashtool, none of the firmware contents are displayed, then when I click OK to begin flashing, Flashtool cancels and then automatically disconnects my device.

Were you able to have any luck yet?

Not with Flashtool, every time I tried to load the FTF, the Firmware Components aren't listed in the middle, no visible check boxes on right either, click OK, Flashtool says the the firmware is loaded and then right after it says Flashing Canceled. The pop-up window that shows you how to connect in flash mode doesn't even show up.
I thought I was screwed, because I originally un-installed a ton of stock apps including SE Home and had aftermarket replacement apps in their place, when I cleared the user data and cache through Recovery mode. My phone wouldn't even boot, I did that because I was planning on re-flashing my device anyways. I know that all I had to do was re-flash it with the stock firmware, but Flashtool just wouldn't even work for me. I even installed it on my laptop only to have it do the exact same thing, very weird.
So I purchased a few credits for 1.99 EUR on WotanServer.com and used their client to successfully flash my Xperia PLAY and now it's back up and running.

Anyone else having any issues with using Flashtool v0.8.5.0 and the R800a_2.3.4_North America Generic.ftf?
I'm just curious if I'm the only one or not who's having this problem.

I am glad to hear you have a working device again

Yeah i had that problem to!
I'm from Croatia,and i saw on change log,that some region's can't see .FTF file's middle things.So the solution for me was to download 0.6.9.1.

If that's the reason why, then that's pretty messed up. Because the same FTF worked before on an older version of Flashtool. I just tried to Google an older version of Flashtool and there no where to be found.

try installing the driver from a earlier version of flash tool

Can't find an earlier version of Flashtool anywhere.

I found Flashtool v0.7.0.0 on this Minus file hosting site and it can read my R800a_2.3.4_North America Generic.ftf file perfectly fine.

i have same problem the ftf files dont show up
same here i click on the ftf file no files i click on the to start flash it cancels on too
i tried the north america one and uk but i need 0.42 on my phone. i have just unlocked my network and now i unlocked bootloader.
i had originally 0.42 but flashed it to 0.62 and my 0.42 ftf files i got from 4 diffrent links all blank when i click on them in flash tool oh yeah there is glitch on flash tool if u click 0.62 which shows files but then click 0.42 it still show 0.62 files which can
confuse you

I had to re-install Windows to totally get rid of the newer Flashtool drivers. Downloaded v0.6.9.1 from the link I posted above, didn't install the v0.7.0.0 update, installed the drivers for v0.6.9.1 and was able to use it with my stock R800a_2.3.4_North America Generic.ftf firmware. I hope that helps.

wow reinstalling windows is a PITA just to flash/root a phone.
Do you still happen to have a link/mirror that works?

This can be helpful for anyone whose ROM isn't working. It is directed to noobs who accidentally ruins their custom ROM so they can start over. Also the reason why I'm doing this is because I searched the forums and I could not find a guide that was simple for noobs to understand, which would always work no matter what you did wrong. I've used this method so many times and it has saved me countless times. I thought the least I could do was to share.
I hope I answered your questions.

Why why why do People use uploaded.to links, and feel the need to rehost files to it. Just link directly to the flashtool and use mediafire for anything else.

I understand this reply is far too late but for people in the future:
You cannot upgrade to ICS when your bootloader is unlocked. You can easily lock it again using this small FTF file. When the upgrade with PC companion is complete, you can continiue modifying your phone with custom ROMs etc.

It is very hard for me to know what is causing this problem. Some minor modifications to the flashing procedure can potentially fix it. Try doing it like this: Open FlashTool, drag the FTF-file and drop it in the dialog box. Press ok and wait for the instructions to pop up. When they do, connect the USB-cable FIRST to the phone and after that hold back key while plugging it to the computer. If the battery of the phone is too low I think it can cause problems, try to charge your battery (if possible) and try again. Also make sure to flash the appropriate FTF-file, accordning to your model.

[Q] Help with L35H

Hello,
I recently tried to update my Xperia ZL L35H (purchased in China) to the latest 10.3.A.0.423 firmware. I chose the C6502 variant because it seemed that this was the same model with some regional variations. All worked well, until I tested the mobile data connection, which was non-existent. Considering that both L35H and C6502 both use HSPA, this incompatibility with the C6502 firmware was surprising. I even used the AOKP ROM for awhile and had no issues with data connectivity.
What's worse, I had my CWM backups on internal storage. My bad, I know. Updating to the 10.3.A.0.423 erased my internal storage, so, no more stock firmware backups.
I would be most grateful if some one could help me either:
*Help me find a L35H firmware, or
*Help me troubleshoot the data connection on the C6502 10.3.A.0.423 firmware.

L35h
Glad to see someone else has the L35h. I'm afraid I can't help you with your problem, but I was wondering if you were able to root it, and how?
I rooted mine with Bin4ry's script, but then made the mistake of upgrading, not knowing that it would remove the root. (I'm completely new to Android and had no idea that the phone would come with a bastardized version of Android that doesn't even allow a Google account to be on it, without rooting.) Now I'm on 10.1.1.A.1.253, but none of the rooting scripts will root it now.

I rooted the 253 using :
http://www.droidkube.com/how-to-root-sony-xperia-zl-and-install-cwm-recovery/
Then lost root after updating to 10.3.A.0.423. I rooted that using:
http://forum.xda-developers.com/showthread.php?p=43288981

Thanks, I might have to do it this way ultimately. I'm afraid of destroying my phone completely, but maybe it's the only way I'll be able to do it.

Downloads here
You have to register and log in to activate the download link on the xperiablog page. Both the C6503 and the C6502 worked for me. Supposedly, the C6503 adds LTE support, but I don't know if there's a hardware difference to reflect that. I've been using this firmmware for a week now, and it's been flawless.
Also, check out Doomlord's easy rooting toolkit (for root) and XZDualRecovery (for CWM and TWRP) here on XDA, both of which work flawlessly on this firmware as tested on my device.

I'd go with whichever one matches where you're at. I'd have to look it up to know for sure. Both the Indonesia and the MEA (Middle East?) ones worked on mine, and I'm in China. Some locations use the same bands, others don't. I'm no expert in how that works. I might be wrong here, but I think the Settings/Xperia/Internet Settings auto-patch takes care of that for you. My 3G (or any data connection) didn't work until I took care of that.

It worked! Took a while to figure out the drivers and stuff, but it flashed easily and now I have a non-bastardized, non-Chinese phone. Seems to run faster and smoother too. Great to say goodbye to the L35h and hello to the C6502!

Haven't noticed any problem like that. Or any real problems. Maybe the notification/SMS sounds are a bit wonky, but nothing that's really bothered me or is especially noticeable. Am still getting notices about how "this version of Android doesn't allow in-app payments" or something like that. I expected those to go away. But maybe it's just because I'm in China with a China Mobile SIM.

Hi Guys! I too brought sony xperia L35H from china....and would like to flash the MEA C6503 version. I installed the flash tool and made the FTF file ready. while just to make sure everything is alright i connected my phone and opened the flash tool. It says "device connected with USB debugging off", although i have enabled usb debugging in my phone. Do i have to install the adb as well or am i missing something. Any help is highly appreciated! Thanks

Its on the recent android build 14.4.A.0.157 kitkat 4.4.4, I have seen a few forums about rooting but they mainly seem to be for the old android build .108.
Any help appreciated. Thanks!

HERE is the easiest way to root latest firmware.

Hey there, I could use some help with this whole root thing as well...
My Z1C is still on .108, but now all the tutorials seem to be for .157 and include flashing with a .108 stock rom???
So do I have to update my Xperia first, then flash it with an older version, root it and flash it with .157???
Some tutorials seem to be removed since they "don't work with the latest firmware anymore"...
Also how do I backup my phone before I root it?
Thanks.

I hope this helps...

Well let me help you both with this, since I have spent around three days wasting my time figuring out how to root the Z1C which appeared later on that I have downloaded the wrong files because the thread it self was providing the kernels for Z1 and not the Z1C. So this is what I did:
It is ok to update your phone to .157 so go on with it, when done make sure your phone isn't connected and is switched off.
1- Download Flash tool from http://www.flashtool.net/downloads.php. After it downloads install it and JUST IN CASE you haven't installed the Z1C drivers go to Your C: drive and click the Flashtool folder then go to Flash tool drivers and you will find the Flashtool drivers installer. Click and install USB drivers and Fastboot drivers, scroll down and select Z1 compact drivers too.
2- Download the two required Z1C kernels and the RootTool as well from http://d-h.st/M9a make sure you Click the DOWNLOAD NOW button not the upper DOWNLOAD button because it is just a useless malware!
then place the two .ftf files in c:/flashtool/firmwares folder. Make sure you place the two '.ftf' files that are in the .zip in the firmware folders you can download them from the attachment too below.
3- Open the flash tool, Click on the flash button (top left) and choose the Flashtool method where you will find the two kernel files you placed in Firmwares folder.
4- Click once on the .108 Kernel and click flash, AFTER THAT press the volume down button on your phone while it is switched off and connect it to USB and wait for the Flash to start and end, it will take several seconds.
5- once it is done disconnect your phone and restart it by simply switching it on.
6- Unzip and place the rootkitXperia_20140719 folder better on your C: Drive. Connect your phone and run the tool by double clicking Install. bat (it might show only install as a name) and keep watching your phone screen to approve. Wait for it to be done and then restart your phone, then switch it off.
7- Follow the same method above to install the .157 Kernel again to your phone and you're done!
PM me if you needed anymore help. Sorry if my guidance is complicated a little bit, just let me know.
All the best!

Thanks for the help. I did however just root my .108 now because I really, really didn't want to unlock my bootloader and flash the kernel.

You don't need to unlock your bootloader to flash kernels or root.157

Really? Damn, must have misunderstood some of the guides. Thanks for the hint.
It's just a load of information at once, and this is my first Smartphone, so I didn't want to go overboard.
Is the .157 update even relevant in any way? And now that my phone is rooted, can't I just flash .157?

I think if you flash .157 you will lose root and will have to reroot by the method I mentioned.

I have D5503 with .157 Will I loose data using this method? If yes, is there a method to root the phone and save all data (including game saves, settings and everythink)?

No, not if you flash 108 kernel, root then flash 157 kernel back with flashtool.

When I run rootkit, it says "Waiting for device". Mobile is connected with PC companion. I have tried to install drivers, tried to change phone connect mode.... Do not know what is a problem. I do not have SD card in my device.
OK passed the "Waiting for device". Now stuck on "daemon started successfully"

So problem solved. The only problem was that the phone has hidden developer options where is USB debbuging. There is a little trick to open developer options so I have enabled USB debugging and than root works.

successfully rooted xperia z1 d5503 4.4.4
@emiratesson thanks i followed the instructions that you gave. At first im having a problem in flashing the 108 because my pc companion is ON im getting errors. I noticed that even though i flash 108 i still have firmware 157 because my current FW is 157 no changes and i tried to root it using rootkitXperia_20140719 still in 157 and a SuperSU app was created in my phone i guess that is the root app.
Current Build: xperia z1 d5503 4.4.4 firmware 157.
