[Q] Some clarification

Ok, I have the play, r800ra, i flashed the r800a stock modified rom to it. Now I am assuming from everything I have read since I have a locked bootloader there is no possible way for me to get to cm7. I cant flash a custom kernal or anything like that. I have to stick to the stock roms. Or can I flash custom kernals and then flash custom roms? Any help is appreciated.

With a locked bootloader,you can't flash anything.How did you even flash the modified ROM anyway?
Anyway,its best if you flash kernels,then the ROMs,in my opinion.

Hmm I couldn't flash anything when my bootloader was locked so I just had to use SEMC for stock updates and with a locked bootloader I couldn't do anything else but root.

After unlooking bootloader, how to root?

hey folks,
I will tomorrow unlock my bootloader on my R800i, and I have a few questions before I do it.
- How to Root then? I will not flash a new kernel, I only want root, because the update to ICS is only on June 2012.
- How to flash? I read always don't flash via CWM only Flash via Recovery?
- Can I flash then a original ICS Update from Sony, because I can't use then the OTA-Update to ICS from Sony or can I lock the BL again, and then update OTA?

once u unlock your bootloader, u cant get ics ipdate.. u need to relock back using .ftf file with flashtool.. go n search.. im wondering what the point u unlock your bootloader without install custom rom or kernel
u can use superoneclick to root your phone.. i hope this help u

No I can't because I have .69 and this is unrootable.

Then u need a custom kernel mate... they are pre-rooted

Question concerning backup before flashing cyanogenmod

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.
Sent from my R800x using XDA

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
Sent from my R800i using XDA

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
Sent from my R800i using XDA

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.

Something easy is flash your new firmware and use a kernel like "Advanced Stock ICS Kernel" to root and finally reflash your stock kernel if your want its improvements, you can unlock your bootloader anytime, and the best custom room is Cyanogen, it just needs to flash an file in recovery mode.

[Q] Installing custom roms on Arc S with locked boot loader

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

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.
