[Help][UPDATE2]CWM and returning to stock

Hello everyone at XDA.
I currently have Cyanogenmod 7.2 on my Xperia Play. I used CWM to install Cyanogenmod. I installed CWM using the apk here. My Xperia Play is an r800a with unlocked bootloader.
I have 3 questions left to answer.
1.If I want to return to factory condition do I just flash the original .ftf file? Will this cause any problems to CWM? Will having CM7 then flashing a stock .ftf possibly cause any problems?
2.The thread that shows how to install CWM has a warning that says
Do NOT use this recovery if you are not in Stock 2.3 firmware.
Well right now I am on CM7.2 can I still use this recovery if I want to flash other roms like miui? What does this warning mean?
Here is the thread
3. Also if I need to is there anyway to remove CWM?
Thanks so much for any help.

I know bumping is wrong but I made this into a new question and rather than posting a new message I edited it.
Any help would be greatly appreciated.

when u flash stock rom it should wipe everything - even recovery (im not sure). Flashing ftf file should give u phone like u had when u got it (but with unlocked bootloader if u did it)

But won't already having CM7.2 cause any problems? Also won't have a custom kernel cause any problems?

when u flash stock rom ftf it overwrite kernel using stock contained in ftf file (kernel.sin)

No. Flashing the ftf will wipe all traces of the custom kernel and any custom rom. It's like doing a factory refresh.

Ok that's good to know. What about getting rid of CWM?

Most Custom Kernels have Recovery In Built, Installing that Recovery wil cancel the Other one out No Value in That app If you have Custom Kernel

[Q] XTXperience 9 problem. don't bite my head off guys.

I am pretty new to flashing ROMS and rooting. I rooted my S2 back in 2011. but since then I haven't. So i though I would do it with the Xperia S.
I installed XTXperience 9, unlocked bootloader. rooted n fastboot. I downloaded cwm recovery. cleared everything. installed the ROM, and It has got stuck in boot loop.
I was on the 6.1.A.2.45 firmware if that helps?
could someone please give me some short instructions and tell me what I am doing wrong I need this ROM looks so cool!
Please don't bite my head off either. I need help. it's only way i'll learn

Please someone

If you have unlocked bootloader, why don't you install a custom kernel? Like Advanced ICS Kernel, ELiTE, etc.

Not sure how to do that yet. would that possibly fix the boot loop I am having??

I've never installed a recovery manually, because I've always flashed a custom kernel with a recovery included, maybe that's why you're having a boot loop but I'm not sure.
If you already unlocked the bootloader you should flash a stock based kernel and that's it.

Yes, and you can also try flashing a custom kernel.
Just follow this tutorial: http://forum.xda-developers.com/showthread.php?t=1527159

I unlocked the bootloader before it got in the bootloop. after flashing firmware I guess it is still unlocked. just need to root it again

If you already have you bootloader unlocked just flash a custom kernel! If you flash a ROM after that, it will be pre-rooted.

[Q] Getting out of a bootloop without CWM

My phone is a Xperia Arc (also known as lt15i) and it is rooted and has an unlocked bootloader.
It runs on Android 2.3.4.
I wanted to install CWM, and followed a guide for that.
Since I can't link the guide, I can just say that it's name was "How to root sony ericsson xperia arc lt15i and install custom rom" and tht is was on listenmefirst.
From that guide, all i did was option 2 for installing CWM.
At the end of the guide, it says "reboot your phone", and I did, and now it's stuck in a boot loop.
I've tried several different keycombinations without anything happening (holding down volume / holding left and right buttons / holding home+volume up). It does however blink a blue light when I hold left and right button, but it seems to have no effect.
So my question is: is there any way to get out of this bootloop?

if you have an unlocked bootloader you can simply flash a kernel that has CWM though fastboot or flashtool
Since your on 2.3.4, this may sound obvious, use a gingerbread kernel.
I used this for pretty much all GB roms i used

So I can't just flash it over to ICS for example?

Then you need a kernel that supports ICS.
there's no possible way for me to brick your phone if you already have an unlocked bootloader. You can wipe everything off and start over. Everything can be solved.

If you just wanted to get out of the bootloop (like your title lol) then you need to flash GB kernel.
If you want to go to ICS you need to put an ICS ROM onto your SD card, flash kernel, then install rom

Thanks for the help, got it out of the bootloop today with flashtool! =)

I did try to find a solution by reading, but everything I found implied I had CWM.

that was also my first question on xda, good old times...
No, it's not possible, ftf. files can only be made by Sony, so you've got to do always the same prodecure for flashing, rooting,....

thank you so much for your answer
so i think i will keep doing that long thing again and again

That's a really tedious procedure you're following. When I try a custom ROM and don't like it, all I do is:
1) If switching between an ICS ROM and a JB ROM and vice versa, reflash the kernel, then reflash the ROM.
2) If moving from one ICS ROM to another, or one JB ROM to another, just reflash the ROM.
3) If moving from ICS/JB to GB or vice versa, flash the stock ROM, flash the kernel, and then flash the custom ROM.
You don't need to keep on flashing the stock ROM, rooting it, installing CWM, then installing the custom ROM. Kernels, as far as I know, usually come with recovery installed. If you're in a bootloop, just follow the pertinent steps from the list outlined above.

Go read the stickys, get some basic knowledge and learn something for yourself, then ask questions about what you don't fully understand, on an existing thread that you found while Googling.

bootloader locked or unlocked because it sounds like you have a locked bootloader, if it is unlocked then why dont you flash a kernel eg. kernel rush with CWM already on it ?

You don't need to install CWM again, even if you're in a boot loop. Once the phone reboots, keep pressing the "down" volume rocker, as you always do, and you'll enter into recovery. If you're moving to a different Android version (for example, ICS to JB), switch off your phone and flash the appropriate kernel. Then all you need to do is reflash your previous ROM or flash any other ROM that you want. However, that's only possible if you've download your previous and/or other ROMs onto your SD card, too. Do you do that before you flash?
I don't have any experience with locked bootloaders, but the user above IS of the opinion that you might be on one. If that's the reason you're having to go through so many steps to flash a ROM, why don't you try unlocking the bootloader of your phone? I'm more than certain your phone's not covered under warranty anymore, and unlocking the bootloader is definitely not going to fry your phone or anything of the sort.

[Q] Can't flash back to ,62

Hello! I'm having a problem with my xperia arc S, I tried to install a ROM (ULTIMATE HD 3.1) but I didn't have the wifi modules, so my phone got stuck on boot, so I figured that I got a bootloop, and went to flash the kernel (562), root again again and flash the new kernel (587) to try and install the ROM again, but the phone didn't root, but I flashed the .587 kernel and can't flash it back to .562. I can't figure what's the problem the flashtool says it's flashed but in setting the "compilation number" just says that it has the new kernel.
So my problem is how can I flash back to .562 and root the phone? I already tried this a few times ([url]http://forum.xda-developers.com/showthread.php?t=2118343[/url]), but it dosen't work. what else can I do? Try with another kernel?
I also tried this, but it didn't work http://forum.xda-developers.com/showthread.php?t=2219711. I don't know if it helps but i have the bootloader locked.
Sorry if repost, google but didn't find anything related. thanks anyway.

If you cannot repair with Update Service, try PC Companion. It should offer the repair function.

Had a similar problem, caused by wrong kernel (at least i think so). Anyho, there was no "repair" option for me either.
What you should do is:
- Flash back to stock GB firmware (0.62)
- Root (using eRoot, it's a one click procedure.)
- Install CWM using RecoveryX is the simplest way i'd say
- Flash the kernel which Jared proposed (can't remember which one sorry)
- boot into CWM, and follow the instructions to install UltimadeHD rom. I'd suggest Tesla's instructions, they are fail-proof. Remember to click on "unlocked bootloader" if your bootloader is locked.
