Hey Guys,
I want to try out cyanogenmod 7.1 on my xperia play. I still have a locked bootloader but clockwordmod recovery is already installed, so if something goes wrong, i am able to go back to my stock 2.3.4 rom. I think for cyanogen mod working right, i have to flash the doomkernel too? So what will happen if i unlock the bootloader, flash a custom kernel and a custom Rom and then apply the backup, i created before? Will i go back to my stock rom, stock kernel etc? I cant find an answer for this :/ sorry for Bad english, im from germany

Despite the fact that you have recovery, you can't use cyanogenmod on a locked bootloader. Cyanogenmod requires a kernel that is different from stock, and you can't flash a kernel on a locked bootloader.

Yes, i know about that. My question is, if i unlock my bootloader, flash a custom kernel, Flash cyanogenmod and THEN use clockwordmod recovery to apply my nandroid Backup, that i createt, before unlocking the bootloader and flashing all These things, will this work? So im back at my stock rom and stock kernel? I really want to try out cyanogenmod, but i want the option to go back to stock, if something is Not the way, i imagined. And i dont know, if the kernel is included in a nandroidbackup. Furthermore, i dont know if a Backup, created with an locked bootloader will work on a device with an unlocked bootloader too?

Sorry, I guess I didn't read your post in its entirety.
The short of it is yes, you can use the nandroid of a locked on an unlocked phone. The nandroid won't backup nor restore the kernel, that must be flashed separately. The kernel is such a small filesize, and the command is easy enough that it shouldn't be a problem. That is, unless you wanted to change kernels while away from a computer.

Thank you, this was really helpful to me so i have to download the stock kernel, if i want everything as it was before cyanogenmod. But thats not the Problem, i guess. I think i'm going to try it out after work, thank you for your fast answers

I'm not entirely sure, but I don't believe there are any stock kernels available. You can use an .ftf file with flashtool, as that sets everything to stock, then restore a nandroid after reinstalling recovery.

Ahhh thats a lot easier than the way, i planned to do this. Thanks

If you restore a nandroid from a stock ROM after flashing the cyanogen kernel your phone won't boot.
You would need to go back to the stock kernel before restoring. Problem is, you don't have a recovery in the stock kernel.
You could revert using flashtool, by flashing stock, then rooting, then install the locked version cwm, then restore.
Or after unlocking the bootloader before even trying cyanogen, flash DooMKernel, and make a backup through the kernel recovery. Then you can try cwm, and if you don't like it, flash DooMKernel again and restore.

Hey guys,
I had an Xperia Play for sometime. I taken the plunge to install a custom rom. I have tried before but I keep failing as my phone gets stuck at the Sony Ericsson logo.
Basically I want to install JJ's HYBRID ROM
http://forum.xda-developers.com/showthread.php?t=1573547
It says to boot in CWM which I did and do a full wipe and flash. I wipe then install zip file.
I am using 4.0.2.a.0.42 rooted with CWM. I amalso using stock kernel. mainly because I dont know how to install doomkernel because I dont know what is fastboot and how to use it because majority of the posts assume you know about this.
Also I want to try to jokawild rom but it tells me to flash to 0.62 baseband. but I cant root it aso how do I install cwm. Am I missing something does doomkernel come with cmw? sorry im a noob
Please help!
thanks in advance
Have you unlocked your bootloader as you use fastboot for that. You will need to flash a custom Kernal like dooms to be able to install custom Roms.
BTW This should be in Q&A section.

Sorry about that yes my xperia play has its bootloader unlocked
Hi, I have a unbranded, unlocked Arc S, running ICS, and I want to flash the 4.04 image, which comes as a CWM zip.
Everything is currently stock but rooted.
The 4.04 update is a ZIP (rather than a FTF), so I think I need CWM installed to flash the update. I can't find anything that tells me how.
I found a easy installer, but it categorically says don't use it with ICS.
HELP!!!
CWM Auto-Installer
Try CWM auto-installer, you can find it in Play Store and it worked to me.
Look in the dev section for the stock ics kernel with cwm is the simplest way.

Use fastboot to boot either a custom kernel like ArcNight or DoomKernel, or cobratos modded stock. They contain cwm, on boot repeatedly press any of the h/w keys to enter cwm and flash the zip on the sdcard.

I only ever found the old beta kernel for ICS, not the final one. Got a link?
I tried the auto CWM installer, and yes it did install onto stock ICS, and I managed to install the 4.04 ZIP, but now it just hangs on the Sony startup screen.
Any advice on how to get back to something that works?
Sorry I haven't looked at that Rom as it's a dev Rom thats been ported, before installing that Rom did you make a cwm backup? Otherwise you install another Rom.

Before flashing a ics rom in zip format you need to flash a complete ics (ftf file) via flashtool /pc companion /seus.
Alright guys, im completely new to this and im very interested on starting to go around and learn some stuff in the Android world, specially with my Xperia Arc. I recently unlocked the bootloader via tespoint and installed an stable version of Cyanogenmod 9.1, however i found some things i would day prefer to have different, so for that i would like to know some things first before i start changing from rom to rom. I hope somebody would give a hand jeje.
1. To change from CM 9.1 to Xperia Pureness for instance, do i need to flash a new kernel on top of the FXP i already have on with CM 9.1?
2. If i would like to return to stock 4.0.4, would it be just flash the .ftf via flash tool?
3. Will flashing the 4.0.4 .ftf file via flashtool install the stock kernel and delete my FXP and CWM?
4. Does 4.0.4 stock works well with FXP kernel?
5. Every time im trying a new rom should i first flash the recommended kernel and then install via CWM?
Once again i hope someone would help me with those questions. i tried to find them on different threads but i couldn't get any with those specific questions...

1. don't know
2. yep
3. yep. FXP and CWM gone
4. don't know
5. entirely your choice. You have to ask yourself, do you want to use the kernel? how is the current kernel doing? what are the details of the kernel? etc.

1) Both are ICS based roms, so in theory it should work (don't forget wifi modules), but I'm not sure about it.
2) Correct.
3) When flashing .ftf in Flashtool there is an option to exclude kernel, so in theory you should keep the installed kernel with its options. But I never tried it.
4) Don't know.
5) Not necessary, unless you change ICS and JB roms.
1. Yes
2. Yes
3. Yes
4. No
5. Yes

I'd just like to say hi to everyone, my name is Mick.
I have an Arc S, originally running GB, but currently running ICS, build 4.1.A.0.562 which I updated to via SEUS a while ago.
I've used DoomLord's one click method to root the phone, have CWM installed, and I've been happy with it since, but I've now decided to see about installing a custom rom.
I've done a lot of reading on here about locked and unlocked boot loaders, and mine's locked so a bit restrictive in what I can do I gather.
What I'd like to know is, a lot of the roms for locked bl's, say based on, or must have, the .587 build, but mine is the earlier .562.
What is the best way to proceed?
Can I flash the .587 kernel with flashtool as I've read that the stock, signed kernels can be flashed on locked bls. Is this right, and does flashing a stock .587 kernel affect rooting?
Any help, or links to whatever I haven't found yet, would be much appreciated.
Cheers,
Mick.

First, .562 update is crap. Sony released a crappy 4.0.3 update, better update if you can.
Then installing stock firmware before installing a custom ROM is not necessary.
Yes, there is difference in .562 and .587 kernels. Apparently, .562 kernels have a security hole in it, which can be used for rooting, however .587 kernels don't have it anymore and you will have to install older kernel to root and then install newer kernel back.
Yes u can flash .587 kernel using flashtool & this will not effect on root... But I will suggest u to update ur phones firmware to .587 (.562 is full of bugs), root it & install cwm then flash stock based custom roms which supports locked bootloader..

It does. 4.1.A.0.562 kernel has a security hole in it, which is used to root via DooMLoRD's method. .587 kernel has that hole patched and that root method does not work.
Thanks for the replies.
Ok, so this means that I can use flashtool to flash the .587 kernel, and then whichever rom afterwards.
I have tried flashing roms with the .562 kernel, and they do work, but I get odd glitches.
The Walkman app in Zelly Cream 2.0 for instance says it has unexpectedly stopped whenever I click on My Music, and the Ultimte HD rom is really good, but the native Movie player won't work and does the same whenever I click on a video.
Each app works ok on one rom, but not on the other.
At the moment I've got the Zelly Cream rom installed and just disabled the Walkman, so had to download another player.
So far I've not had any issues with boot loops or anything, but I have been wiping properly before installing.
I have got a stock .587 kernel I found on here, so I'll try flashing that and see if it's any better.
It's a shame the boot loader is locked, but I've also read that removing the sim lock can fix this.
Thanks again for the info. :good:
587 kernel
Sorry, has anyone got a link for a generic .587 kernel as when I search, the ones that come up have been modified in some way, and my boot loader is locked.
Thanks.
Got it
Ah, it's ok, I think I've found it.
The first one I downloaded was reproting LT15 in Flashtool, so after a bit more searching found it here
http://forum.xda-developers.com/showthread.php?t=1838830
Should be ok.
Just download the whole ROM, but choose only kernel to install.
Sent from LT18i with custom firmware by myself.
Your phone's not covered under warranty anymore, so why don't you try unlocking the bootloader? Would barely take a few minutes.
Hi, Flash new .587 firmwar..... flash .562 kernel only.....root phone.....flash original .587 kernel only.....this video helped me a lot.
