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.

i search over and over and i check the site daily to find any way too root officially global world.431 without re flash (ready to root firmware)
i need root to slove small internal memory problem
any way id like to ask what is the disadvantages of flashing (ready to root firmware)?
and if i flash (ready to root firmware), can i update my mobile normally via witless?
there are no disadvantages, it's just the normal 4.0.4 FTF with the 4.0.3 kernel.
just don't flash the FR because tether doesn't work from some reason.
and for sure there is no differnt with 4.04 kernel and 4.03 kernel?
and if u have the rom, how is the battery with you?

read the tutorial carefully, after you done rooting you need to flash the 4.0.4 kernel
the battery is almost the same as GB for me.
rite, i didnt notice that
thanks alot
Hey XDA,
I had an Xperia PLAY R800x running stock rooted 2.3.3 with a version of DooMLord's DooMKernel that is 1.6 Ghz. The device was acting buggy so I used Flashtool and flashed it back to 2.3.3. I rooted the device and ran my usual bloatware removal. I couldn't locate the same thread I got the kernel from so I went to DooMLords page and found the v2 kernels for the CDMA variant. When I try to flash the kernel all goes well but when I try to boot the device it just sits at a black screen. It doesn't even show any form of recovery (which I still can't figure out if its included in these kernels). I want to flash the 2.0 Ghz kernel. Please help!!! The thread I got these kernels from is this one http://forum.xda-developers.com/showthread.php?t=1368636
EDIT:
Turns out the original kernel came from this thread http://forum.xda-developers.com/showthread.php?t=1605631
IS your bootloader unlocked? If not you cant use the kernel anyways. Note the link you posted is a valid CDMA kernel, My only suggestion for you is to use flashtool and use R800x uncheck everything except kernel. Flashtool will reflash the stock kernel onto your device that has doomkernel in it.

The device is unlocked and I've tried everything like what you've said.
EDIT: I was able to flash the v1 kernels but the autobrightness was annoying. Also the cm 9.1 kernel wont flash either allowing for cm 9.1 to be installed
I flashed this kernel. Works great!!! http://forum.xda-developers.com/showthread.php?t=1487473&page=2
Personally pax's kernel gave me bootloop after a reboot on my R800x.
Hi, I've had my Xperia play for a few weeks and feel like i want to install a new rom as the default 2.3.4 software is a bit sluggish. Ive already rooted and installed CWM and backed it up. I have a locked bootloader and the first instruction to installing the rom is to install a stock rom, Don't i already have that installed as i haven't installed a custom rom before? Should i just skip this step? Thanks in advance! My Model is R800i and the build is 4.0.2.A.0.42.

it depends on which kernel you want to use.
.42 firmware does not support custom partition layout, so in order to use kernel like Turbo Kernel by CosmicDan or Lupus Kernel by wedgess (both with custom partitions) you'll need to flash .62 firmware or newer, wipe userdata and system and then flash the kernel.
While this isn't needed if you want to use, for example, DoomKernel

But i have a Locked Bootloader so i cant install Kernels right? so should i just skip this step or should i get a new stock rom?

Still havent answered my question, I dont really want to unlock my bootloader if its possible to just flash the rom but do i have to flash a stock rom even though i haven't installed a custom rom before as wouldnt i already have a stock rom? The rom is a GB rom so i dont have to unlock the bootloader, it even has installation instructions for locked bootloaders.

I've said you, you should skip this if you don't want to flash any kernel with custom partition layout
But remember that if you remain on stock kernel you cannot flash no other rom than stock based ones

Hi,
I'm having trouble getting back from a KitKat Rom to an JB or ICS ROM.
I'm getting stuck with the firmware. It's flashing OK (I've tried several different ones), but when I boot up and try to get into CWM it just sits there on the firmware logo (e.g. the LUPUS logo, or the Rush logo).
Is there something fundamentally stopping me going back to an ICS or JB firmware, after I've previously had KitKat running?
HELP
Oh, this is the Kitkat ROM I originally installed, and it's included kernel:
http://forum.xda-developers.com/showthread.php?t=2570072
If I flash that kernel again, I can get into Kitkat successfully, no problem at all.
As above, if I flash any other kernel, I just can't get into CWM.

You can flash stock ICS firmware using Flashtool, then flash a JB custom kernel with a recovery. From there, use the recovery to flash a JB ROM.

Thanks for your reply.
What is the need for flashing an ICS kernel first?
I'll give it a go, but flashing a custom ICS kernel with a recovery I've been unable to get into CWM.
I'm probably doing something really stupid.

Flashing ICS is recommended first since this will restore you phone's memory partitions. KK uses different memory partitions to make it run properly. This will also wipe your phone's data and allows you to do a clean install that should eliminate most errors that you encounter during ROM installation.
Ok, thanks so much for the advice
I'll give it a go and let you know how I get on!
Ok, I'm back on Gingerbread stock firmware
Android v2.3.4, Build 4.0.2.A.0.62.
I can't find an ICS based FTF file - everything is either 404 or on hotfiles, which is dead.
I've unlocked the bootloader (which I thought I'd already done, but maybe the flash of the firmware undoes that?)
Not sure where to go from here.

Check my signature for stock firmwares, there are working links for Arc and Arc S.

Hi i got this sony xperia ion.
I unlocked the bootloader last night and when i tried to update to latest software version (6.2.B.221 i think) it showed me an error whivh i figured cause of unlocking bootloader.. so i gave up on updating with pc companion. Now im tring to just flash the custom rom and kernel but it says i need rooted device to flash.. so i searched about rooting ion and found one thread that i need to flash prerooted kernel.. one that im tring to flash is .elf file and it's stock kernel, prerooted, has cwm and init.d and says (no OC) but will i still be able to use apps that requires rootd device like root explorer, cpu manager after i flash latest firmware and flash new custom rom and new kernel?
I know you cant understand what i wrote.. so..
My situation
I unlocked bootloader before i update it to latest firmware.
Im going to flash kernel that is prerooted, has cwm, init.d. in order to flash latest firmware
After flashing latest firmware, im going to flash custom rom and kernel that is in (rom).zip file
Will i be still able to use superuser? Or like apps that requires rooted device?
It's my first time using sony devices.. please help this nooby noob
and i appreciate any tips or stuff like that will help me thru finally custom rom
(Sorry about my bad English)
