Boot, and I'm stuck. The CM7 loader shows up, I see the unlock screen for about 2 seconds and then the CM7 loader comes back. Over and over and over again. I've tried completely wiping and starting from scratch but that's not working. I've tried both the latest stable release and the latest nightly. I read elsewhere on an EVO 4G thread that someone had a similar issue but the fixes they suggested aren't flying.
I am relatively new so please don't make too many assumptions as to my understanding. Speak slowly and use little words. Hand gestures help.
What kernel are you using and which firmware were you on before you flashed cm7?
sinkster©
The kernel was something.something.56, I believe. (or was that the firmware?)
I'm sort of stuck in this place and I can't get out. I suppose if push came to shove I could find those posts about putting my phone back into its stock state. But I'd rather not. The stock Sony experience was terrible.
Firmwares ok then, did you use the kernel in the cm7 zip or from DoomLord (i.e. fastboot flash boot boot.img)?
sinkster©
I first tried the boot.img from Doomlord (v15). But that wouldn't even get to the home screen so then I tried boot.img from the cm7 zip.
i have same problem
Best idea is to start from scratch. Check fxp thread for anyone else having issues too.

You have to use Doom's CM7 kernel on CM7, not the one for SE's ROM.

keep getting random reboots anyone know why?
Resolved
OK, this has been quite a journey but I was able to get CM7 working.
1st, I had to put the phone back into a stock state, like I just got it from Sony. My phone was unbranded and not from a carrier so this wasn't too hard. But I can't even sort of retrace the steps I took to get it back to the stock version of the SE Xperia Arc software. I never strayed from XDA so all of the answers are here, but what a rabbit hole that was.
2nd, the "latest stable release" on the CM7 site that I linked to in my original post is, in fact, completely unstable. Random reboots, stuck at the loading animation, etc. You need to use version 7.1.0.1 instead. Download that version, flash the boot.img that's contained within that zip and then update in fastboot to the 7.1.0.1 update.zip
This took far too long to figure out but I was able to get the thing running. And it looks so much better than Sony's terrible UI. What on Earth were they thinking?
If you downloaded CM7 on Cyanogenmod websites, I think you have to delete anthalservice.apk or something. It is located in /system/app/ or /data/, can't remember correctly.
OK, here it goes.
I have a R800x CDMA Verizon Xperia Play
I had bootloader unlocked successfully by alejandrissimo.
I am rooted.
Today I decided to try the MIUI rom for CDMA.
It required custom kernel, and recommended Kieren's darkforest kernel.
I installed that kernel via fastboot with no problems.
Upon turning on phone, i get a page that says Sony, then I get ANDROID page.
Then it just stays on ANDROID. I can tell that it is not frozen because I can see the waving lines going across.
SO, I decided to just go back to stock kernel then try again.
BUT, I cannot get into fastboot!!
I hold search while connecting usb, and the led blinks blue once, then continues with boot.
I am at a loss.
I Can get into CWM.
Please Help!
Edit: I just noticed that after holding search then plugging in USB, the light blinks blue once. Then about 25 seconds later, the light turns solid blue for about 3 seconds. Then just to orange for charging. During this time, I can not get fastboot to recognize device, nor does my computer recognize any devices.
OK, first - don't panic! I had some issues myself with this, but it's easy to resolve.
First - if you want to return to stock, the easiest thing to do is to download flashtool from this link:http://androxyde.github.com/Flashtool/
And the FTF of the stock ROM from here: http://www.mediafire.com/?u70ci3bdzak3u9e
Follow the directions on the Flashtool website for how to flash back to stock. This will make your phone just like it came out of the box. It does not touch the SDCard.
Second - Make sure the kernel you flash in fastboot is the one intended for the ROM you want to install. Also make sure you copy the zip file of the rom you want to install onto your sdcard. Then enter into CWM and do the following:
- clear data
- clear cache
- clear Dalvik cache (under the advanced menu)
- clear Battery Stats (same menu as above)
Then use the menu "install zip from sd card" (or whatever it says ) find the zip file you copied onto you card and load it. Reboot when finished and you should be good to go. Please be aware some ROMS take a long time to boot up the first time around.
Good luck.

ok, small problem with that.
when I click to install flashtool, it tells me that it is not available for my region (Central USA).
I do have a nandroid and titanium backups made just before flashing.
Use this link - I forgot about their link blocking us. But use that site for instructions.
http://www.mediafire.com/?t2pxz1j7snieeos
Having just unlocked my bootloader this weekend as well, I don't know what to tell you there. But since you can get into CWM, reverting to stock is a good way to go. Then try flashing the firmware, etc again.
still stuck

OK, thanks for your help, but I am still stuck.
I can not get the device to be recognized.
So, now I need an alternate method.
I will attach the kernel that I flashed, maybe I could flash a ROM that could be compatible.
I tried to flash MIUI v4 from near the end of the MIUI port for CDMA thread (pg 9, I think) , which paxchristos and a few others reported working fine for the R800x
I flashed the kernel that was listed to use in the same post.
But, when I tried to flash the ROM, CWM told me that it was not compatible with my device. It checked the ro.build.fingerprint and determined that it was not compatible.
Maybe another rom would work, and then I would be able to work on it from there

Yeah, that seems to be the wrong boot.img. It should be called boot-v2.img.
EDIT: WOW - I just reread your post after posting mine and realized I pointed you to the same spot!
Try this ROM which is a version of CM9 that Chevyowner got working for our R800x. I know it works because I'm using it. http://www.mediafire.com/?1xnh54i6lvnnh73
It is the same one, i just renamed it because i thought kernels had to be boot.img to flash correctly. I will try that rom when i get home.

just an fyi, you can name kernels whatever you feel like (I'm not sure about spaces, I use linux, so I never have spaces in names anyways )

Flashing now
OK, I just downloaded and flashed the ROM about 3 minutes ago.
I cleared everything just like you told me to.
It installed with no errors.
You may be right about long boot times for first boot, otherwise I have a really bad kernel.
It has just sat on Sony screen for the past 10 minutes.
It hasn't even went on to the android page that I got before.
Hoping that it will Work.
Assuming that it doesn't, what would be my best next move?
Can I flash a kernel (Such as doom_lord's CDMA Kernel) via clockwork?
I think I saw a video about it for the Samsung fascinate, however I seem to recall something about needing an s2 file or something??
I will update as soon as I get something. (hopefully good news)
Update: It has been about 20 minutes now and still on Sony screen.
Now it has been 30, im starting to get worried. Should I plug in? Should I just let it be? Should I let it die? Should I battery pull?
Major Edit: I got impatient and just battery pulled. I then tried to get into CWM, but failed. THen I got a bright Idea, why not try fastboot with the new rom. IT WORKED. I WILL NOW TRY TO FLASH A NEW KERNEL AND SEE IF THAT HELPS.
it should not take 30 minutes to boot, only thing i can think of right now is to redownload kernel (boot-v2.img) and reflash that.

is this your kernel, or someone else's? If it's yours/you have a working copy, could you post an md5 so the op can double check it?
Sent from my R800x using Tapatalk
nope not my kernel, and i doubt i have an original working copy as i added 2 lines so i could mount my sdext partition.
Finally!
OK, I am now back up and running.
I went through every kernel and rom for CDMA play, and got nowhere.
I ended up getting Doom's kernel to run. It worked, and booted to android... Then stayed at android.
Then I decided to flash my nandroid i made, and am now working on stock rom W/ DoomKernel.
The ROM seems to be lagging a lot.
Since everything is *working* now, what kernel/ROM combo can anyone verify working for the Play R800x CDMA.
I would really like CM9 or ICS based roms.
Thanks for your help getting me out of this mess!!
EDIT: Nothing seems to be working!! My touchscreen seems to be non responsive, no phyiscal keys except for the power key seem to be working with my original ROM now!!! Maybe somebody could attach a copy of the stock kernel for my device, so that I could start from scratch.
If you're using keiran (darkforest) cm9 kernel the md5sum for it should be: 74a5be2bf95322b8c45780d9daeda4fa

@zeeky120 - I'm sorry you're having so many problems. For me when everything seemed hosed, I started over by using Flashtool and flashing the ftf file I gave you links for. Then once it came back up as stock, I started again from scratch. Depending on what your goals are, you need to flash the proper kernel for that. Then get into CWM. Clear DATA, CACHE, DALVIK CACHE before you do anything else. Then load via zip file the rom you want to install, making sure it matches the kernel you loaded. And, whether necessary or not, I always wipe the big 3 again, just in case. (Call me paranoid, but it helps! )
Ok now up and running on stock everything working great just like out of box. The only thing I have done so far is to root. I want to do it right this time. I would like to flash cm9 based miui for r 800x. Could anyone provide detailed step by step instructions and links for download. Thanks in advance.

Closing Notes
This thread has reached its end, because my problem has been fully solved. Advice to future users, always clear the big three, and when in doubt: use flashtool to reboot the ftf. Right now I am up and running on CM9 (use the link in Chevy's signature to download. I can verify that it works great on CDMA. (faster download speeds than stock!!!) Thanks for everyone for all of their help, and I hope to be contributing to development in the near future.
I am trying to install CM9 on my Xperia Pro. When I flash with CM9 ROM, the phone is not booting up.
Then I have tried to install CM7.2 which is working fine. But in CM7.2 I found that phone volume is very less. I can hear the ring sound when it is in my pocket.
I bought ROM Manager Premium and then tried installing different versions (downloaded ROMs from XDA Developers forum and other websites, may be same versions with different file name) of CM9. Whatever the ROM I have tried, the phone is not booting. It is stopping at initial Free Xperia Project Logo. Even if I wait for 30 minutes, it is staying in the same screen. I have to remove the battery and restart the phone and then switch back to CM7.2.
I have attached screenshots of my phone details. Kindly help me installing in CM9 or any other ICS ROM on my phone. The worst part is, I cannot repair the phone using Sony Ericsson PC Companion as it says, phone cannot be updated because the phone contains modified software.
I am a newbie for Android. Please help me installing in CM9 or any other ICS ROM
Hello.
I think that your problem is the different boot.img .
First of all you have to flash the new boot.img via fastboot (you can found it in your android-sdk folder. otherwise just download it.
After flashing this new boot.img (you can find this img in the *.zip file of the ROM)
you have to enter clockworkmod-recovery (at boot hold volume down or tap it some time).
Next would be deleting data, dalvic and installing your new ROM.
Hope this will help you.

Hi, just wanted to report the camera is not working in skype in Cm9 on Xperia pro (Mk16i), but it's maybe already known.
EDIT : FXP123
I flashed my R800x using the instructions on the DiXperia 2 post. It seems to boot fine, but when it finally comes up there is no home app or really anything for that matter. I'm sure I'm just missing something stupid. Thanks in advance for any help you might be able to provide me.
[edit]
Don't ask my why this worked, but I pushed my ICS kernel back and re-flashed FXP135. That booted fine, so I tried DoomLord's kernel and flashed DiXperia 2 again - now it boots fine and I get a home screen.
Now, if I could only get my radios working...
[edit]
Well, what a waste of time I guess. FYI: DiXperia 2 does NOT work on R800x (CDMA). Not a huge deal, too bad cuz it looked like a nice rom.
[edit]
TIL - On an R800x, one must flash a different kernel before flashing the desired kernel if that kernel is the kernel that is currently flashed to that particular device. If not, you won't be able to boot into CM9 or recovery... It's been a long day.
Hello and good afternoon,
I received this Xperia Arc (LT15a) from my dad to fix and I can't get it worked out so here it is
When you unlock the phone the screen responds to touch, I can swipe back and forth as one would expect. If you keep your finger on the screen or touch it atleast every second the screen stays responsive. If however you stop using the screen, sometimes for 10 seconds most the time just 1 second and the screen will no longer respond. In order to get the screen to respond you have to lock the device and unlock it again, as if refreshing it or restarting the touch screen service in the phone is the fix... temporarily.
I saw a thread somewhat like this and the fix was to downgrade to make sure no bad firmware had been put on so I downgraded to the 4.0.2.A.0.42 that the phone shipped with. This didn't solve the issue. I tried all sorts of firmwares thinking perhaps one would work. My dad tells me that this started happening when he updated the phone to 4.0.4 through the Sony upgrade software.
Has anyone run into this or do you guys believe this is more likely to be a hardware problem (which seems strange because I would think the screen should either work or not)
Thank in advance.
Hi @Laydas,
This is a weird one, for sure.
I've seen something similar on my phone, and for me the problem was definitely linked to an "upgrade / downgrade" kind of thing.
My solution was to install another rom.
So now I guess your bootloader is locked (because the phone is not rooted).
So the best thing to do is to try flashing a stock rom using "flashtool".
Here's some pointers to help you on your way...
Try this thread - http://forum.xda-developers.com/showthread.php?t=1304634
you're looking for info on flashtool, and on stock roms (I think that some stock roms are available in post 2 of the thread)
On top of that, there is an older thread (so a bit outdated) here - http://forum.xda-developers.com/showthread.php?t=1133650
It has good background reading thread to get a grip on all the ideas involved.
Good luck
I forgot to mention that I had already rooted the phone
I have used flashtool to restore the stock rom which didn't solve the issue either.
I have now taken the phone apart to check for loose connections, everything looked good.
I put the phone back together, tried it out, I still have the same screen issue.

OK, wow. This problem is really sticking around.
So my next question is: - Do you have an unlocked bootloader?
If yes, then try flashing a custom kernel and a custom rom.
My favourite ICS based rom is JJ's Hybrid - http://forum.xda-developers.com/showthread.php?t=1537717&highlight=jj+hybrid
It works 100% with the ArcKnight kernel.
If your bootloader is locked, then you cannot flash a custom kernel. You can still try try the JJ Hybrid rom to see if it sorts out the problem.
At this point I'm running out of ideas. For me this issue was software related, so flashing a different kernel and rom fixed my problem.
It seems like your issue is software related too (because it popped up after an upgrade), but if you flash a rom and a kernel, then there's not much else that you can try flashing,,,
OK, maybe there's also a base-band you can try flashing - There's a base-band thread here - http://forum.xda-developers.com/showthread.php?t=1688049
So try a custom rom and a custom kernel, and if that fails try updating your baseband to 72 or 77.
That's all I can think of to completely overhaul your phone's software.
Please let me know how it goes...
Take care,
Hotfingers
The bootloader is locked on this phone unfortunately.
This phone is not like my other phones, even trying to get a custom rom onto it is a hassle as installs from zips in CWM almost always fail.
Pushing roms from flashtool works but I couldn't find the JJ hybrid rom in a ftf format for flashtool.
At this point I will continue trying to get a custom rom onto this phone when I have time but it has dropped off my priority list as it is being so difficult haha.
Thanks for the help, hopefully sometime next week I will be able to go through some of these steps and get back to this post on what helped
