What would be the best way to run stock 2.3.4 rooted on an R800i? The stickies are outdated around here and all root methods I've seen refer to 2.3.3 or 2.3.2.
Would the best way be to root on 2.3.3 then update to 2.3.4 OTA and use something like OTA rootkeeper if I want to keep the stock kernel?
If I am unlocked can I just ftf or update to the current stock firmware and then fastboot a kernel with root built in like doomlords kernel? Is that the best method if you want a custom kernel but stock 2.3.4?
Really I am looking for the best way to run stock rooted 2.3.4 with a stock kernel and with a custom kernel to compare.
Yeah, you can flash any stock rom using a ftf file and then update the phone to the latest version with OTA or PC Companion, but i think neither of them works if your bootloader is unlocked. In this case you must find a ftf file with the latest 4.0.2.A.0.62. I found it on this thread: http://forum.xda-developers.com/showthread.php?t=1409355

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.

Hi
My xperia play is currently on jb 4.1.2 (paranoid android rom 2.57.1-wedges with the turbo kernel) and very nice it is too,
I however want to restore it to the original uk stock rom that allowed games to be played etc so i can sell it as i have bought an xperia t.
Do i just use flashtool (Using the guide in the general section) and install the original GB stock rom 4.0.2.A.0.42 or is there anything else i have to do / beware of / Will this also flash the kernel back to stock. I am assuming that the turbo kernel wont work with a stock GB rom.
Thanks

Worked fine, the only issue i had was the phone wanted to update, but it kept giving me a message in pc companion that it could not update as it had been modified, I unrooted it and tried again same error, so tried a full flash again with the .42ftf, same error again. Finally reflashed with the .62. ftf, its not trying to update anymore. I think there is a problem with the root as it says its not rooted anymore but flashtool says it still is
Now to work on my new xperia t.

Hi
Hope you can help. My aim originally was to upgrade from 4.0.3 to Slimkat 4.4.4 but I have never done anything like this before and I have messed it up. I was using this guide http://droidors.com/2014/07/07/upda...android-4-4-4-kitkat-with-slimkat-custom-rom/ but deviated from it when the guide didn't work for me.
I upgraded to 4.0.4 using PC Companion.
I unlocked the bootloader on my Arc S and rooted using Eroot. Then I tried to install a custom recovery from here http://forum.xda-developers.com/showthread.php?t=1345741&page=2 which said I had to go back to 2.3.4. I did this using Emma from Sony Mobile.
After the custom recovery tool installed I loaded the Slimkat files onto the sd card and booted to the recovery mode but got an error when trying to install Slimkat (it said something about the update is for LT18i but my device is "" (which it isn't?!)
Anyway after that didn't work I wanted to just go back to normal 4.0.4. I couldn't get Backup TA working before I unlocked the bootloader so I have lost the DRM keys.
The custom ROMs I have seen all seem to require stock 4.0.4 so I seem to be stuck on 2.3.4.
I am so confused, if anyone can help either with getting me back to a version of 4.0.4 or my original goal of Slimkat that would be much appreciated.
Thank you

You can anytime revert back to 4.0.4 stock rom:
1. download flashtool http://www.flashtool.net/ if you don't have it already.
2. download stock firmware from http://www.4shared.com/rar/cwrJE_jE/Lt18i_41B0587_1254-8596_Generi.html?refurl=d1url
3. Placing firmware in flashtool. Note: only .ftf format files to be placed. If the file is of .rar/.zip then extract it to get .ftf file
Copy .ftf to C:/>flashtool>firmwares
4. Run Flashtool>Click on the flashing button>Select flashmode>Ok
On they very left side you'd see the firmware name and version. In the middle the contents of it and on the very right side some options. Mark them as shown below.
5. Select OK. Now flashtool will prepare files and ask you to connect your phone. Follow the steps.
On devices with no hardware back key, use volume down key while connecting
OR
after that use this to root:

then you can flash any 4.4.4 rom
