[SOLVED] [Q] Where can I find my phone's original firmware?

TL;DR version available at the bottom of the post.
Hello, I have a Sony Xperia Play model R800at from AT&T that originally ran 2.3.3 out of the box, and I read that you can root a Sony Xperia Play by flashing the firmware to 2.3.2 then rooting it and afterwards upgrading back to 2.3.3.
So here's the kicker, I mistakenly downloaded the 2.3.2 firmware for the Sony Xperia Arc, and my phone refused to boot after flashing. Next, I downloaded 2.3.2 firmware for Sony Xperia Play from here, and after flashing that my phone was able to boot but "android.process.media" is force closing every few seconds.
I gave up on trying to root my phone and just wanted to make my phone normal again so I went in search of my phone's original firmware in order to flash that in hopes of bringing the phone back to normal and stopping "android.process.media" from crashing so much. So after searching up and down and high and low for my original R800at 2.3.3 firmware from AT&T, I couldn't find it anywhere! Does anybody have it or does anybody know how to fix my phone?
TL;DR: Stupidly flashed wrong firmware, can't find right firmware to flash. Firmware I'm looking for: USA Sony Xperia Play model R800at Android version 2.3.3 from AT&T.

Just flash the north American 2.3.3. Its way better then the att version.

Can you please tell me where I may get that firmware from?
EDIT: Will it come with the bloatware that came with my phone? Because I got different bloatware when I flashed the generic UK firmware and believe it or not I miss my old bloatware.

Not much bloat really. It's in the development section I think.

Apparently my phone was still under warranty, so I sent it in and got a new one for free so everything is all fine and dandy now. Of course, I didn't tell them that my phone was acting up because I flashed the firmware.

Were you able to access 4G with Generic 2.3.3? (Did the "H+" appeared?)

[Q] where to get stock at&t R800at firmware

I am looking to return my xperia play and need to know where i can find the stock at&t R800at firmware that came with the phone originally. I have since purchasing it put the R800a firmware on it (Generic North American) and since i am within my 30 days i would like to return it but want to flash it back to stock so to prevent any lash back from an at&t rep.
If you have any info on this subject i would be very grateful. My at&t Xperia Play is running the generic N.A. 2.3.3 firmware which i have gingerbreaked but still have the bootloader locked.

Good luck! The R800AT users are the very minority in this place and no one seems interested or cares to make a ftf of the R800AT. Just look at a couple people requesting the ftf a week ago.

Well your wait is over. Here it is straight from SEUS. Working, tested on my own phone.

thanks - been looking for this for a while

I used this and for some reason either my phone didnt take the FW or it was wrong. The phone read that it was still R800a. It had nothing to do with AT&T FW??

I'll be trying it myself here soon.

Can that flash tool be used to flash a non-ATT firmware to an ATT phone without unlocking the bootloader? Or even a custom ROM for that matter?

Blue Xperia Play 4g, need baseband..having problems

Hey guys, I was hoping I would'nt have to do this but i'm at a loss now.
I own the blue xperia play 4g phone and currently using it with straight talk service with their unlocked sim. Everything was fine until I decided to start trying out custom roms.
No matter what I tried, I could get them to load, work , function ect BUT I had weird issues where people could not hear me for the 1st call, but if I called them right back they could. It just seemed to be random and I could'nt put my finger on it.
So I flashed back to the stock 2.3.3 R800AT firmware, and then updated thru their Sony patch they made me do on the phone...and everything was fine again.
Well I got adventurous again, and UNLOCKED my bootloader. So NOW....after doing custom roms, I CANNOT reload my old R800at 2.3.3 firmware and get the OFFICIAL update from them. So i'm stuck with an upgradeable working 2.3.3 (this is the 2.3.3 before the update they put out, I know it does'nt go to 2.3.4. but its some kinda 2.3.3 update) with NO further updates.
So after tons of research i'm HOPING its the baseband I need ??? I dont know what else to do. Only other option is if some kind soul wants to send me over their AT&T r800AT 2.3.3 UPDATED firmware I'll just go back to stock but i'd prefer to keep using my custom roms!!!
***maybe if someone who has the blue xperia play 4g version, would post the "baseband" version they see on their phone, even that would help!!!***
Any help would be great and more than appreciated.
God bless and thanks guys,
Jason

Oh my friend, you are in the same boat as me. xD
All you need to do is get the stock 2.3.3 AT&T firmware, But you can also use r800i firmwares and update to 2.3.4 with the latest firmware.
Theres a thread somewhere containing the firmware, if not you can find it on google.
(Which is what im doing right now with straight talk) only negative thing I see is so far H instead of H+.

If alejandrissimo unlocked your phone you should have OTA updates. If you unlocked it with another method then im not sure what to tell you, gotta find the updated FTF files.

Guys good news here
I was correct in thinking it was the baseband on our phone that is causing the problem. I think its due to the fact we are 4g rather than 3g.
So how did i fix this problem??? Simple. I was able to use the doomkernel v13 (any seem to work), actually install the rom of choice, (i'm using Jokawild 2.5), and then downloaded/installed baseband file -36.
I also installed the -36 libs package that was somewhere posted on here its the new .386 version.
Everything is working now and i'm happy. Going to save the baseband/lib files so i have them forever incase something happens.
Take care, God bless and thank you for your input/time. I could'nt go another day with them stock at&t roms!!!!

Hello hello, I need your help. I've got the generic North Am. 2.3.4 (.42) and I'm having this problem. I've got an unlocked bootloader and I want to install the baseband file. Can I do that with a generic rom? What is the process for installing a baseband file and libs package? Where can I get these files? Thanks.

I think I have the same or a similar problem. I frequently encounter a similar situation where it could take 10+ seconds before the other person can hear me speak, but I can hear them the whole time. By now most of my friends and family know how to deal with it, but before they would just hang up on me. Then they could hear me if I called them. If I reboot the phone, it fixes it for a while, but then it comes back after some time and takes another reboot to resolve.
My phone is a SIM unlocked, bootloader locked Xperia Play R800a model from last year's Google I/O. It uses the same frequencies as AT&T for 3G and 2G and I'm using it on AT&T as well. I have the Generic North America 4.0.2.A.0.42 (Android 2.3.4) ROM installed, and it has Baseband 8x55A-AAABQMAZM-203028D-56.
I found a separate thread with the -36 Baseband here:
http://forum.xda-developers.com/showthread.php?t=1469473
I'm considering flashing this over my current -56 Baseband to see if it improves the situation. As I recall, I never had this sort of trouble when I first got the phone. It's really only been since I updated to Firmware .42 that I've had these problems. Is it safe to do this?
Thanks!

I wanted to add that on Friday I installed the -36 baseband with mine and I'm getting 4G+ (I hit 12MBs at mobilespeedtest.com). And my calls have stopped being cut off.

Awesome! That's also funny because I also installed the -36 baseband last night. So far, so good. Calls and data both work as normal. I'll need to do more testing to be sure whether it fixed my problem or not.
Now did you just install the baseband or did you also flash or push the libs to it as well? All I did was use Flashtool to flash the baseband .ftf file.

[Q] About FTF files and their interchangeability

after being a lurker for almost 2 years at xda-developers, I have finally reached a point where I need to ask a question. I've finally purchased an Xperia Play R800a, and I noticed that even though the custom ROMS always works with both R800i and mine, i sometimes see that they require a certain firmware to be installed, which are most of the times not found in R800a version (like the .62 one). I've read some reports of people installing R800i firmwares in R800at phones (AT&T) so I was wondering if I want to install a custom rom which install instructions ask me to install a R800i firmware (like .58 Enhanced or .62), can I simply flash the firmware it requires despite my phone being an R800a unit or should I find its closest correspondent but made for the R800a?
Thanks in advance guys.

I was like that too, i have the R800a too, let me help, its completely interchangeable! I Highly recomend the .58 enhanced v2 (v3 has a few bugs).
For instance just use flashtool to flash it, than install CWM to flash any GSM custom rom out there that is GB unless you want to unlock your bootloader which costs money to install ICS and JB roms. Hope it works out for you Dont forget to thank

Question for flashing : C6506 Rogers Xperia ZL

Hi guys,
I am new to android coming from apple. I am looking to update my xperia zl 4.1.2 build number 10.1.a.1.395 to android 4.2. I have never flashed the phone before but i do however rooted my phone using i believe doomlords mod. I have also an issue with the in ear peice when calling i notice the volume is extremely low when i am making calls. If someone would let me know the steps to fix this issue and the update that would be great. As far as i know i need flashtools and the 4.2 android update? Just want to know which update i would need. My phone is originally a rogers xperia zl but its been unlocked to use any carrier. The bootloader is also locked on this phone.
Thank!

Update your phone over the air. (settings, about phone, software update) and use doomlords tool to root again.

Trying to get the update from OTA wont work in your case since you have never flashed the phone and are probably on the stock Roger's firmware meaning you wont see an update available until Rogers pushes their 4.2.2 update with their own bloatware which may take a while.
Just flash the latest FTF firmware C6506_10.3.A.0.423_Unbranded.ftf (stock Sony firmware) found on here on XDA and flash it with Flashtool. Then use doomlord's method to gain root. Very easy stuff... Dont wait for Rogers to update unless you want to wait forever... Carriers are usually slow to update their stuff.
