R800i 4.0.A.2.368 UK on the Verizon R800x

This is a long shot, but this is something I've love to know whether it is possble or not. I have heard a couple people say that they pulled this off.
Obviously, the R800x Xperia Play on Verizon is the stripped down version of the UK version. The R800i has the whole Sony Experience, and I wish to have that on mine. So I thought to myself, couldn't I just flash the R800i 4.0.A.2.368 UK ROM found here:
http://forum.xda-developers.com/showthread.php?t=1221105
onto my R800x Xperia Play? And before anybody says it, I KNOW that the network won't work, no phone and no sms. Only Wifi would work. That is fine by me. I would be perfectly fine with this just being an Android WiFi gaming device with the whole Sony Experience that the R800x lacks.
I've tried flashing this R800i ROM with FlashTool, and it keeps failing. Which sort of surprises me, because a couple of others in the thread in the link I posted above claim that it worked for them. (I can't post there. Dev section. Not enough posts yet)
Is is just a fantasy that will never come true? Or am I simply doing something wrong? If I was not very clear about something, please let me know, and I will edit this post with corrections. Thank you for your kind advice or suggestions.

i think its been confirmed that itll brick it someone tried to see if they could enable the sim card slot flashing a generic rom to the r800x yes the r800x has a sim card slot has a plastic thing covering it right behind/on top of the sd card

Well I'm not trying to enable the sim card slot. I just want the ROM on there so I can replace the horrible VCast with the Playstation Store, give me the Sony Ericsson widgets, basically all of the stuff that the R800i gets to have.
And since this phone is just my backup (WiFi only) device anyway, no network access does not concern me at all.

Actually, yes, this! I may not want the whole she-bang, but if I can find a way to replace the framework that wants to pull everything from the VZWapps store *shudder* then I would be a tad happier. Just replacing the "Play" app doesn't do it. So where is the framework that tells it where to go?
Second, I know there are portions of the SE Experience framework still in the R800x, as some of the widgets, when installed, still work. Also, there is something blocking the normal facebook app from installing an account hook like on other stock phones, even though the rest of the r800x is "stock". I think we can pretty much all see that the R800x was not "Stock" but rather just stripped. Almost all the hooks are still there, plus some that are VZW specific.

UPDATE:
I have gone ahead and tried this, done some testing. So far, I'm making progress!
I have gotten the European R800i ROM on my R800x Xperia Play.
It boots up just fine (new boot animation).
However, I am stuck at one spot. I cannot do anything except bring down the notification bar, view the Xperia Play games when I slide out the gamepad (VCast is gone!), and change USB options when plugged into the computer.
Here are the steps that I have taken:
-Full stock restore with FlashTool
-Flashed doomlords boot.img with the command "fastboot flash boot boot.img"
-Flashed frasertag's system.img with the command "fastboot flash system system.img"
-Flashed the system.sin from the R800i Firmware (I extracted it) with the command "fastboot flash system system.sin"
-Disconnected USB then turned the phone on. It boots just fine.
Now the reason that nothing actually functions at this point is because I only flashed the system.sin from the R800i firmware (this is just a theory!). Trying to flash the whole ROM in FlashTool will result in an error and fail. I have read in another post that a trick to bring full functionality (besides the network) is to create a Nandroid backup before flashing all of this, delete the system.img from the backup, then restore the Nandroid backup after all of the flashing is done. The restoration part has got me stumped so far..
I will keep trying, and will ask the guy who I got this idea from how he got past the restoring backup stage (where I'm stuck).
I am determined to make this work! haha

During my experimentations, I bricked my Xperia Play a couple times. Luckily it must have been a "soft brick" or something, because I was able to restore it by doing a full restore to factory stock. Nothing else would register in the bricked state.
I do not have a SIM card for this phone at the moment. The only SIM card I have on me is the 4G card for the Droid Charge.
I tried restoring the Nandroid backups without including the system.img in the restore, and it still wouldn't fix the problem.
Here are a few theories I have on why it didn't work, and what might work:
-The Nandroid backup was from factory stock, and NOT rooted.
-The inability to do anything on the homescreen may be due to the lack of a launcher.
So what I'm going to try next is:
-Do a Nandroid backup while in a rooted state, and all of the Verizon related software removed. Try restoring that.
-Download the system dump from the R800i, and install the Launcher APK via ADB Shell.
Not giving up.

I have succeeded in putting the Sony Ericsson Experience from R800i onto the Verizon R800x.
I'll post pictures a little later.

I am sorry for "abandoning" this thread, but I got incredibly busy with school. Here is what's going on. I got good news, and bad news.
Bad news, I got the ROM to flash onto the R800x, but encountered problems to the point where it's not even worth posting anything for.
Good news, so instead, I took a good chunk of goodies from the R800i dump, and put it on the R800x. A good number of the stuff works, but some doesn't. All these apps/widgets come straight from the R800i.
I am not taking the credit for any of these finds. I am just sharing things that I have found after searching the internet high and low.
First is the SE launcher. This will make your phone look and act a lot like the R800i. This includes the SE app drawer, the folders, the dock and the "jiggly" movements. Everything works except for the themes. Here is a download link:
http://www.mediafire.com/?zuq8hsexodjk3bx
Next is the Playstation Pocket/Suite app. This is the official Playstation app from SE. On the R800x, the widgets work perfectly, the app works fine, and the game launcher looks beautiful. The only problem is that when going to the section to buy more games, it doesn't show any games available for USA. But that's what PSXperia is for. If you aren't familiar with PSXperia, you must check it out.
Here is the link for Playstation Pocket:
http://www.mediafire.com/?mmhduygvlmsjdim
Here is the Media Shortcut widget. This just lets you select music, wallpapers or videos all in one widget. This of course comes from the R800i.
http://www.mediafire.com/?w41bp8wr7d81rb8
Here is the Photo gallery widget. I really like this one. It revolves in a circular motion with your fingers. Works fine in portrait mode, but does not work in landscape for me.
http://www.mediafire.com/?1yuvjhf2f7m1b4l
[ROOT REQUIRED:] And lastly for now, here is the Sony Xperia Play game launcher WITHOUT the VCast. You must remove the Xperia Play game launcher, and VCast. You can remove these using Titanium Backup. Then install this one. This removed VCast for me, and instead gave an icon in the corner that takes you to the Xperia Play optimized games from the Android Market.
http://www.mediafire.com/?5kmog06w4s3qn3i
UPDATE: jgregoryj1 has posted a better and easier method to remove VCast. See his post below (it's #18). It's way simpler, but know that root is still required.
I cannot seem to get the SE R800i music widget to work without crashing. But of course, the R800x stock one and others work like normal, so oh well...
Again, I am not taking any credit for these finds. I just tried these things for myself, and I am now sharing them with any who are interested in making their Verizon R800x's look and feel like the way the Xperia Play was MEANT to look.
In closing, I just want to reiterate, I am very sorry about not accomplishing the task of getting the ROM to work 100% (it was still unusable). But for anybody who wants the R800i look, these should tide you over.
Thank you guys for your understanding, and thanks to everyone for making XDA such a good place.
Travis

I wasn't even aware that verizon held out on these features. Thanks for getting then out there.

These features were indeed stripped from our model(s), and it was very disappointing to learn that they didn't include the Playstation Suite on these. Oh well, for I'm glad I didn't return it now. I love this thing.

Don't use flashtool. Use Fastboot (ie Fastboot flash system system.sin)
Also the radio will still work if you flash chevys nandroid backup after flashing the UK firmware.
Sent from my R800x using XDA App

I was able to get rid of the vcast market in the xperia play launcher by removing the vcast app from the /system/app folder and rebooting. If thats all you want to get rid of then just do that. The android market will then be in plce of the vcast. Although I have flashed te UK rom and have the full Timescape rom onmy phone for a few weeks now. Its pretty sweet and fast. But kudos for posting the helpful information

Also you need to flash Doomlord's kernel for 3.0.1.A.0.145 found here: http://forum.xda-developers.com/showpost.php?p=15805471&postcount=2
Then apply chevy's FTSv05 CDMA Patch v2. You will have a fully functional phone with the exception of multimedia messaging.
None of this works with 4.0.A.2.368 Roms though. I have been working on trying to get the radio functional on the newer Roms.

Or you could pull the kernel from a tft file like I did. dooms kernel had too many problems for me. No wifi, low volume, etc.

Switching ROMs and pre rooted kernel

I have done some reading, so if I missed a link with the answer, pass it on...
So I am currently using ZedomaxEpicTouchKernel[v3][1.6GhzOC][Quadrant 4500+][SU3][CWM]
I am looking at ROMs now, even though I said that I wouldn't, and it seems like the ROMs come with their own kernels.
I want to do a 2.3.5 ROM, possibly cyanogen, but don't want to lose the 1.6g kernel.
Do I flash the custom ROM, then just odin the zedomax kernel over it?
This is my first sammy phone, if it was a moto I wouldn't even be posting.
Thanks
PS - my CWR only backs up/restores after I pull the battery out (then it starts working). Any advice on this is appreciated too.

I'm in the same in the same boat. I am from an EVO 4g and I guess am used to just flashing that in that method.
I'm not exactly sure what to do here either. I sent a google+ message to max, but I really don't even expect him to respond.

Where r u getting that 2.3.5 rom? Was it baked for THIS device? U can't just flash any rom onto the device. Look at development section for roms 4 this device.
Cyanogen has not been brought to this device yet, but here's hoping.
Someone else correct me if I'm wrong.
Sent from my SPH-D710 using XDA App

He is looking for a rom.. Drop the 2.3.5. He clearly does not mean it.. However his question and the reason for this topic remains..
For example, I am running AE (So I assume bubby's kernal + CWM), but I would like to use the zedomax overclock kernal V3. However anything and everything I thought I knew about flashing seems to be gone... It isn't bad I just need pointed in the right direction so that I can educate myself on what is going on here.
I assume this has to do with the root method. Simply because I don't understand why my recovery is attached to my kernal. I'm used to just running CWM.. Again. I'm lost.

Yeah, I think I see what you mean. My last two devices were htc so I'm kinda lost too. I guess my eyes caught the 2.3.5 & Cyanogen reference and I got confused. I believe that if you flash a rom with a different kernel it will replace whatever you've got. At this point I would be very reluctant to flash anything without cwm coming with it.

[Q] ROM question for Telus SGH-T989D

I have a simple question and i think ive seen some mention of it, but nothing quite definitive
I want to root my SGSIIX from Telus(989D), and ive figured out that i can follow the same instructions as the T-mobile version here:
http://forum.xda-developers.com/showthread.php?t=1332103
It suggests a ROM below that was originally posted for the T-mobile ver, is there any T-mobile branding on it visually such as boot screens etc?
Also...
If a ROM works flawlessly on the tmobile version, will it also work flawlessly on the telus version by default. Ive been eyeballing the possibility of Cyanogen or MIUI, and juggernaut...but i wanna make sure EVERYTHING works perfectly after doing so, or if there are certain things that might not work
Thanks! (sorry im rather new to android modding so im trying to learn)
And yes i searched around, but have only seen a few ppl post in threads saying 'it should work', then some say theyve had problems..so thought id make a post!

i have the same questions then you the tutorials i found are for the t-mobile rom
not the telus one but reading other post they are the same rom
but i dont whant to take the risk lol

the 4g network was gone could not connect to it only 3g was working
i uninstalled most apps with titanium backup pro but i end restoring to the back up i made from CWR
gonna give it another try when they are going to release a rom that is from telus version of the phone
i hope it helps you

The 4g is broken for me to ...it seems like the modders are only interested in the t-mobile version to, so it looks like even rooting(based on the fact that the rooted rom is also a t-mob) wont even be possible

What do you mean rooting? All you need to do is flash CWM and then the SU package, no need to change any ROM at all.

I rooted my Telus device using the T-Mobile instructions and all was well at home, it stayed on the Telus network and also keep 4G speed.
I went to work with it, where Telus service is very poor, and as soon as I lost Telus it roamed to Rogers and did not try and return to Telus even though I was in an area where Telus signal was good.
In the end I changed the device to wcdma mode only and set the device to manual provider and selected Telus and have had no problems with 4G or not being on Telus...

Do you happen to have a link? I followed a guide on this forum that said the easiest way was to flash the rom!

I rooted my phone, it still said 4G.
When I installed beastMOD it says 3G. But I am definitely getting 4G speeds (20mbps). So.. maybe a bug with the difference in phones?

ughhh
trust me...stick with the telus rom. its actually better code then tmob. newer drivers and less debug code. I tried the tmob and its gawd aweful. if u want goodies...slap a kernel on it then theme it. best way to go imho.

For Telus you don't need to change roms when you root.
I'm running the stock rom on my phone with a modified kernel to allow the phone to run faster and the v6 memory mod as well as removing the clock from notification bar.
Installed Titanium and removed a bunch of the crap that came stock with phone too.

Get the recovery.tar from here: http://forum.xda-developers.com/showthread.php?t=1315390
Flash that through ODIN (PDA mode in ODIN, Download mode on Phone)
Then, place the SU update (http://goo-inside.me/superuser/su-3.0.5-efgh-signed.zip) on the root of the SD card. Reboot to recovery, select install zip from SD Card and select the SU update. Reboot and you're rooted without having to use another ROM.
The reason why you keep getting a 3G signal when you are getting 4G speeds is because you are using a T-Mobile ROM. The way the Telus one works, if you don't have a ROM that is based off of Telus's source code, even though everything works perfectly fine, your signal will be "3G". It's really only an aesthetic thing, as the speeds themselves are 4G.

So what kernel do you recomend.
and is it the telus kernel with sudo rights ????

Not sure for kernel, I just used the stock one. I just finished flashing Synergy, haven't tried anything yet! I seem to have this issue where I need to re-search for my network after going into download mode (normal behavior?) so I need to get that working before I want to benchmark.

I fully tested a custom juggernaut rom and a rooted Telus stock rom and the juggernaut rom is waaayyy better. Smoother more options as well as better signal. True it says 3g but actually I get better speeds than stcok Telus rom. In my opinion after several tests don't use stock Telus. It may be better code than T-Mobile stock rom but custom juggernaut rom is way better

Thanks guys!
Ive got it rooted with the lightning blue theme going, and froze a bunch of apps with Titanium that i hate seeing running in the background.
one last question though(i think)
I once had a Fascinate, when i flashed a voodoo mod kernel and tried to remove it, the phone became bricked and the entire insides of the phone had to be replaced
Can flashing a kernel mess with the boot loader(which i assume is cwm)? Is there anything i need to do differently when changing kernels as well, cause so far with ROMS ive just been resetting and flashing with ease.Also do Roms come with kernels, so flashing a rom will either go back to default/other kernels?

[Q] Xperia Play and Cola

So, I installed Cola on my XPeria Play - my first custom ROM ever, and also my first true "root" ever. Yay!
So, it seems like all is well... except, well, I can't access the 'net... period. I have no 3G/4G at all, and I can't enable wireless without the phone rebooting... and disabling wifi again.
Anyone experienced this or know what might be going on?
I would post this in the Cola thread... but, well, I don't have the required 10 posts yet... heh.
For what it's worth - all I want is a WORKING (fully) phone that doesn't have all the pre-loaded crap (like some of the games) taking up space.
(reposted from the general forums per another members request)
Yeah, I'm kinda new to the whole custom-rom thing... like I said, I really just wanted something faster that didn't have all the bloatware - it's the 800at as far as I can tell, but it looks like I can't unlock the bootloader (the info doesn't show when I attempt to view it, and from what I read here, that means I can't unlock it?)

Is this from a stock kernal or Doomlords? If its doomlords, you might need to add the network modules.

Sent from my beautiful Xperia PLAY using Tapatalk 2

Ah, aha... thank you so much! Lol, told you I was new to all this
I'll give the suggested ROM a try and let ya know how it turns out!

Well, quick update - i flashed the new firmware - that seems to have worked well, but I have no 3G/4G again - I'm attempting to install the new ROM now - I'll report back how that goes.
I did have one issue - my computer still reports that clockworks mod is installed even after the firmware flash... but I can't seem to run it within the system - I'll try to run it from boot to do the flash - if it doesn't work... well... I'll have to think of something lol
EDIT - so, further update... I can connect to wifi, but can't go anywhere on it, including the play store or to put in my google account info. I also still have no 3G/4G access... and clockworks mod doesn't work.
I'm... really not sure what to do at this point. Followed the instructions to the letter but... well, yeah. Now I've got a smart phone that apparently isn't so smart lol

Okay, so, in a "stroke" of genius, I realized that it was the APN's causing the issue (I didn't have any) - so I simply copied them over from my wife's phone (she also has an XPeria Play). So, yay, now I have internet access and 3g/4g again...
Now, next thing I need to do is figure out how to put clockworks back on this thing with my computer thinking it's already there lol
OH, and for what it's worth - at present, my network mode is WCDMA preferred / GSM - trying to use the GSM only doesn't work... at all SO I guess I have a WCDMA phone?
EDIT AGAIN - Okay, so I got Clockworks back on it, I'm re-rooting it now... hopefully i can get the ROM installed then!
New Edit - Okay, I'm at the point of using Clockworks to install the new ROM - however, it gives me an MD5 mismatch... hm...

Uh oh
Since you have the MD5 mismatch I would try downloading the file again. Also make sure you wipe the cache partition and Dalvic cache in advance before flashing.

You don't have an unlocked bootloader. You must install ROMs specifically meant for locked bootloader.

Okay, so, the phone is working normally now with just the updated firmware - however, I still am having a few issues with MD5 errors with Clockworks, and I'm not sure exactly how to remedy this - found a few suggestions online, but I'm afraid to try any of them without a little more guidance

Can't use mobile networks on Custom Rom & Boot Loop

I can seem to access my mobile network when using a custom ROM: It always says no service.
If I go back to stock, then I can access it but the moment, I install a ROM, it is no longer available.
Background info:
I got a brand new Xperia Play a couple of months ago and successfully installed Pacman Rom on it.
I then recently switched to Racing XPLAY. I then wanted to try out some of the other ROMs and so installed them using the excellent CyanLabs tool.
At first everything worked fine. However, after a while, each time I would install a ROM, I would get stuck in a bootloop.
Eventually, it got so bad, I had to flash an FTF, using the ones in this thread.
Since doing that I can't access my mobile network on any custom rom. Additionally, I am unable to use Cyanlabs to install roms automatically, and have to do it manually.
I would appreciate any pointers. Thanks!

Not being on here long but I've done a lot of reading since I have.. From what I can understand there's two types of ROM's, CDMA and GSM, you might be custom installing the wrong type to your phone *(R800/800i need GSM, R800a/800x need CDMA), also from what I've read some may need extra modules installed to correctly run certain parts of hardware. Try another Stock rom for customising, (big list here) Also, loads of people here favour Flashtool to install Rom's, maybe trying that instead?
As I've seen mentioned lots of times on here... Read, re-read and read again, your probably missing something so simple that'll be stopping it working 100%
*I'm sure someone will correct me if I'm wrong.. Newbie and all that.

Thanks for your help. I live in the UK and have a R800i, so I have only being installing GSM roms.
I have also tried via, flashtool, but same problem.
It's weird, if I FTF back to stock, it works fine. It's just when I install a custom rom.
I've searched really hard, but haven't found anything that helps.
I really would appreciate help, as I don't want to be stuck on stock!

If you game a lot your best bet for good gaming performance is stock debloated. I have tried many a custom GSM roms here and as much as I appreciate and have the utmost respect for the devs here I always come back to stock debloated as it gives the best performance.

The FTF I am using is the generic UK one. Is that the correct one to use?
I tried going back to a backup I had made before all this started, but its the same problem (no mobile networks). Does this mean it is a kernel issue?

BASEBAND?
I did also face this issue when i flashed a ftf with incompatible basebands.
I had baseband 54 by default, then i flashed an ftf while baseband was unchecked in flash tool, and bang, cellular networks, data, etc were giving issues.
I would recommend 2 things, check if you have a sim locked phone, in which case you will need to sim unlock it
secondly, search the android development section for krisdee's Xperia NXT, which has a link to firmware 4.0.2.A.0.58(enhanced). flash it. I think it has baseband 64 which is good as per my experience. Then flash any ftf with baseband unchecked in flash tool.
Thanks,
