Confused about locked bootloader and custom roms? - Xperia Play Android Development

After all my inactivity on the forums i've seen so many things go un-noticed
so i now have CWM on my xperia play locked bootloader/ locked sim etc.
Full backup on CWM of my phone, can i now successfully install CM7 from cyanogenmod team?
if so can i safely go back to my backup of stock rom?
also will CWM will still be on my phone if i install cm7?
i have CWM insntalled from SE Xtreme tweaks

you cant install cm7 because it need a different kernel and with locked bootloader you cant flash a kernel.
But you can try it??

No no,cm7 requires kernel which can't be flashed via cmw only fastboot which requires unlocked bootloader

I use these rom and not work ,my bootloader is locked

I think this may be the same as the problem I am having....you have to restore a nandroid backup of the rom you are wanting to use since you have a locked bootloader and it also has to be a stock based rom. Stock based as in does not require a kernel to be flashed in order to boot.

cant access xrecovery.....

I flashed doomlords v4 kernel after flashing trips MIUI rom and have lost access to xrecovery. It just gets stuck at the Sony Ericsson logo. I went to superuser and turned on compatibility mode but nothing changed. Any help?

First, why do people keep posting questions to the dev section?!
Second, use flashtool to revert to stock firmware and start over.
First of all, wrong thread and second, wrong site. Ask in modaco site.
Rom is not using xrevovery03. And in kernel is xrecovery03.
Wondering if you are on baseband 71 and did you flash cm7 kernel by mistake.

Why modaco? The problem is not the ROM, as I'm currently using my phone to post this. The issue only came up after flashing the kernel.

Trips Roms are not compatible with custom kernels as he has stated before. you cant flash a custom kernel unless you have an unlocked bootloader (even then i'm not so sure). it stuffs the Recovery. Trips rom doesnt use Xrec 0.3. as a previous post stated you'll have to restore back to official 2.3.3 and re-root reinstall xrec and reinstall rom.

Hmm ok. So I need to flash the global generic 2.3.3 ftf and then do the downgrade / upgrade method? Then I can reinstall xrec and the rom?

Kernel will work. I tried an it worked. I do not what went wrong.
But use xrecovery03 before you flash kernel. Use flash tool GBready to get xrecovery03. You will reconize it by the logo of Z
woah! Don't start again with flashing 2.3 rom, it's unneccessary! you can manually copy/paste the needed files to the rom with a file manager and set the permissions right. But I would recommend you to unlock your bl, flash dooms stock 2.3.3 kernel for unlocked bl's and then the v04b kernel for locked bl's with recovery.
Why? Simple: using dooms stock 2.3.3 kernel means you can't loose xrecovery again, even if you format system partition and reboot you can enter xercoery again, cause it's included in the kernel. Also you can remove then the xrecovery.tar from your system partition cause it's not needed anymore.

You are joking right?
Have you tried this CM9/
Neo
Neo V
Its the OFFICIAL STABLE cyanogenmod for the NEO. It is VERY STABLE and has everything working.
Apart from that, to revert back to stock, just flash a stock kernel (Or any modded kernel for stock) and restore the backup you made before flashing the cm9 rom.

The roms that you have suggested are for "neo". i am using "neo v" and the reson i wanna go back to stock is because i con not onnect to my gmail account with cm9 over data connection. Its giving me some sort of an error: can not establish reliable connection....."...
now for going back to stock ics can i just flash it via cwm and i will be back in stock ics? dont i need to flash karnel or anything like that?

I just added the link for the neo v
Yes, you need stock kernel.(or modded kernel for stock roms)
The kernel for CM will not work with stock rom.
My suggestion is to try the stable cm9 for neo v from my link. If you are still unhappy then download a stock kernel, flash it it fastboot then restore your stock backup in recovery.
Do remember, if you flash stock kernel you will have to install a recovery. Or you can flash the alliance kernel from this thread

Rule number 1
Always backup, just in case you **** up!
Anyway, no problem, there are several options.
Find a stock .ftf in the dev section and flash that in flashtool after you have flashed the stock kernel.
Or, repair phone software using PCCompanion.
This will revert your phone to factory settings (Out of the box).
Or just follow the instructions in any "stock" based custom rom. I recommend Ice cream Pureness. Its a very good stock ICS based rom, fully functional and stable

Help needed--Custom ROMs, Bootloader??

hi everybody!
I need an help. Sorry for my bad english, I'm only 16 and I'm Italian.
I have an Xperia Mini, it's my first android phone, so I'm not very good at android modding! I downgraded it from ICS (Official) to Gingerbread (4.0.2.A.0.42 build) and I rooted it. Then I installed ClockWorkMod recovery. I don't have an unlocked bootloader, but I want to flash a custom ROM based on gingerbread. If I flash it, can I go back to stock rom with CWM's restore function? And If I can't, can I use flashtool to flash it (I have the .ftf file that I flashed for downgrading)?
Thanks very much.
Welcome to our forum
You can flash a gingerbread custom rom for locked bootloader with cwm, but be sure it is for locked bootloader!
If you take a backup in cwm, with backup/restore -> backup before you install the custom rom, you can restore this backup to go back to stock. Flashing the stock ftf will also work, you have to decide if you want to restore or flash, but if you take the backup in cwm it will backup the whole firmware with all apps etc :good:
Thanks! :good:
But do I need to flash a custom kernel? Or can I keep the stock kernel?

For locked bootloader custom roms it's the stock kernel :good:
For unlocked bootloader roms you need to flash a custom kernel, but this is only possible on unlocked bootloader

Normally it should work, but the problem is there's not specified if it is for locked or unlocked bootloader. It's stock based so it could work on locked, but it is recommend to flash a kernel. You could try it, but it could be you get a brick
When it's bricked, (mostly) you can't boot in recovery so you have to flash the stock rom with flashtool
Another little advice: If you install an ics custom rom on a gingerbread phone it could end in a brick. I had this when I was on locked bootloader, so I updated to ics (while keeping root, how to do this is in my rooting guide) and installed it again.
You can try an ics custom rom on your phone running gingerbread, just install it. But if it won't boot, flash the stock gingerbread rom and update it with root to ics
Ok. But before installing a rom, I have to do a full wipe, and wiping all will delete the CWM recovery?
I think I'll first upgrade to ICS officially. Can I use pc companion? or I have to flash the .ftf file of the stock 4.0.4 firmware with flashtool?

1.) make nandroid backup
2.) factory reset/wipe data
3.) wipe cache/partition
4.) format system
5.) wipe dalvik cache and battery stats.
6.) flash ROM
7.) flash supersu fix, there are lots of links out there just incase you have problems with root. this will solve your problem if u have locked BL
8.) if you lose CWM, you can use led deletes x-recovery tool to install cwm after you boot your rom
BUT TAKE NOTE THAT THERE ARE CERTAIN THINGS YOU MUST DO IN "SOME" Custom ROMS like Hasa(flashing lockscreen after 1st boot)
MAKE SURE TO READ THE THREAD's INSTRUCTIONS FIRST
Ok i read all the guides...now I'll update to ics and root it. Then I'll install a custom rom.

[Q] LWW BL format /system and CWM?

Hi!
I'm new here and I have a question.
I have a Live With Walkman, locked bootloader, ICS .587 and rooted. I installed CWM for ICS through X-parts and made a backup.
Here my question. If I format system and then restore the backup, will I restore CWM too or have to install it again?
Thanks for answers and for all that I got here for my phone and for defy too.
Excuse me, my english is bad
AW: [Q] LWW BL format /system and CWM?
CWM should be there after the restore

Do you (or anyone) know if i can get back to stock ICS restoring the backup after install a rom like Xperia Nexus that works with locked bootloader?

if you try any ics based rom, then yes. In 2011 xperias you can restore the kernel, thats why you can't restore ics backup when you are on gb rom/kernel and vice versa.
btw: if you try some ics based roms for locked bl, then (i think all of them) is pre-rooted, but you must install cwm again. (As i was on locked bl and i tried jj's hybrid rom, then i must install cwm again)

Xperia mini pro root CWM Recovery after

Hey guys long ago I rooted my xperia mini pro and put CM 9 or 10 then I went back on Stock then again i put some radom kernel and and rom, then i wanted to put a rom here from te forum but when I put the kernel and try to go to recovery it wouldn't start the recovery the screen is just black
So i went back to stock !
now my question is how do I root again X_X
and how do I put CMW reocvery, because I want to put this : http://forum.xda-developers.com/showthread.php?t=2220537
maybe you can find here what you search

Since u tried cm, I am sure ur bootloader is unlocked.
So the easy way to root now would be to flash any custom kernel. It will be prerooted.
If you still want ti retain the rooted stock rom
Flash kernel and flash stock excluding kernel
Or flash stock and then flash kernel

Yes most (I believe all) custom kernels will have cwm ( or twrp,) so yes.
Try goin to dev section and find the list of kernels in stickies and find a jb kernel.
