question

my question is do i have to unlock the bootloader to install a custom kernel?? i have the xperia play r800at running the clockwork mod v5.0.0.2 with a recovery installed

Is it the r800x or the r800i. Regardless, the bootloader must be unlocked. The phone version just decides if it is possible or not
Sent from my R800x using XDA

its the r800at so how do i know which roms will work i really dont want to brick it that would suck lol

There are really good roms out there that cannot brick your phone. Anyway if it does brick u can always fix it yourself. The rom totally depends on what u what. Speed, looks,etc.

You need to take out the battery and look for a "R800_" the blank being a letter like x,i, or c. If you don't want to unlock the bootloader try the darkforest rom

The COLA rom is really fast but simplistic and the market is incompatible at this point with google play being released

The IT-rom is based upon COLA so it is blazingly fast but inherently has the out of date market.

Also none of those require a custom kernel and are well built on the stock kernel. If you need any links, let me know

Ah the delightful soft brick. To fix download this http://www.softpedia.com/get/Mobile-Phone-Tools/Sony-Ericsson/Update-Service.shtml and follow the instructions to update given after install.
After following the instructions to "update" your phone; use the zergrush root method http://forum.xda-developers.com/showthread.php?t=1321582 to re root, reboot, install this apkhttp://www.google.com/m/url?ei=aW1f...kQFjAA&usg=AFQjCNFpwILPy8Rr-eZVSBJ8hrxtAyACAA, and run it to re install CWM.
Your apps should be there but if not:
Reboot into CWM and flash the nandroid I hope you made before doing ANYTHING. If you didn't make a nandroid, restore a titanium backup or start re downloading the apps you had installed.
After your done, backup your apps with titanium backup and make a nandroid backup as well.
Also I'm curious to what rom you tried to flash and the settings you uses when flashing as I might be able to help you flash it correctly.

welll thanx for the info im thinking since im a noob at this i tried to install 3.0.5 darkforest rom but it might have been the wrong one becuz there was a 3.1.0 as well im i wiped sd card before installing rom too i waited about 30 mins for phone to boot but wouldnt boot at all

well darforest 3.0.5 is what i installed but i may have confused it with the 3.1.0 too grrrrrr also you said to take out battery and search R800 well i tried that and it wouldnt work grrr

Make sure you got the darkforest 3.0.5. You can get it OTA here. Also make sure ypu untick the options that say GSM only and also untick the option that says "format /system"
Type this into the dialer: *#06#*
If it comes back with a MEID you have a R800x. If it comes back with a IMED you have a R800i. Also if you are on Verizion in the US then you have a R800x

All of these don't need the unlocked bootloader. COLA and IT-ROM are nandroid backups that must be placed in the folder /sdcard/clockworkmod/backup. The downloaded files need to be extracted into seperate folders. Eg: .../backup/cola6 or .../backup/IT-ROM. The files can be flashed through the recovery option in CWM.
As for darkforest rom, it needs to be downloaded, and the zip file must be put into the root of the sdcard. From there it can be flashed through the option in CWM to select a zip file to flash.
Darkforest rom also uses the AROMA installer (touch screen capible rom installer) which is fantastic because it makes installing and selecting instalation options incredibly easy.
Also what is this wiki? I would love a link to this.

Aroma installer is in the darkforest rom zip. It was that installer wen you flashed it.
Okay the imei means you could unlock your bootloader if you wanted to. It also means you have the r800i.
To flash darkforest rom, download it via darkforest ota (see previous post), move it to the root of the sdcard with astro or es file manager. DO NOT UNZIP! Go into CWM, wipe the cache partition, then find the darkforest rom zip,and flash it. When the installer comes up, UNTICK the option that says "format /system" then press install. After it is finished SAVE THE LOGS. Then try rebooting and tell me what happened

ok kool ill do that now and im glad i have the r800i now i know a lil bit

Yeah us R800x users have to pay to have our bootloader unlocked and the dev has to be on.his computer to do it. Oh well.
Let me know how flashing goes incase something pops up that's bad.
Also the sony ericsson logo that pops up that has the green thing above it is the boot animation. It will be there for like 5 min. It just takes forever on the first boot for some reason.

Connect your phone to pc companion and look at the thumbnail pics. One of them is backup. Never used it, but it makes backup of you contacts, messages, emails. But apps, you have to look your self, because idk

Rooting Sony Xperia S - The Missing File

Well I tried to use Bin4ry thread and his script to root my device but no luck
http://forum.xda-developers.com/showthread.php?t=1886460
since it's asking u ..on the very first step to open Sony's app - backup and restore -which is unlike found there when u install clean custom rom.
So - I'm not saying his way isn't good -it's just furstrating that i coudlnt find this app anyway on web so went back to original room rooted -
also with other thread - http://forum.xda-developers.com/showthread.php?t=1742992 - Thanks to Sharaz22
and extrackted the file for you all -to have better ,faster and easier way to root with Bin4ry post.
thanks to him and all others that helps up on this great website-
i wanted to add this file as a comment on his thread -but the website think i'm dumb enough to even commnet.
so I hope - Bin4ry if u see it -plz add it to your thread.
So there it is for u.. ( u can send it to your mobile by using bluetooth\gmail\usb cable-gmail would be to easiest way for noobies i think to find it and install it through there..)
I'll soon to be posting here noobies guide for easy rooting your Xperia S in 30min - if u would want that.

no luck here unfortunately.
Here's the message I get whenever I click to run the app on my Tipo Dual:

Same on my LT15i - seems there's something missing. Both versions of the APK give the same result, it just doesn't work.

i had no issues
i had no issues on using this app after running the programme i had a back up and restore file in my xps that was not their before told me to run the root file did it all works perfect i used the normal mode in the run me file from bin4ry... option 1 i think..... even for a locked bootloader it worked as after doing my own xps that has unlocked bootloader i did same steps on my gfs xps and she has a locked/b/l worked first time no worries

on the Xperia S I had no issues as well - but the S has backup&restore on board. The Xperia arc doesn't have a backup&restore app in the ICS upgrade - and apparently there's a reason why (copying the respective apk from the LT26 doesn't work either)

[Q] Need help - ROM issue - phone restarts at boot animation

I am not an expert in this area. I just wanted to get rid of bloatware from my Xperia Arc (2011 edition). So I followed the procedure given here
http : // talk.sonymobile com/thread/97327 (basically unlocked boot-loader, and flashed using another firmware to get root access).
The phone was working well for 2 months. One day I turned on Bluetooth and phone crashed. Now it starts and at the boot animation restarts. I gave it to service center but they said they will not repair because of some policy.
Please suggest a solution to this. (I have USB debugging enabled already on it).

I will check if this mobile has recovery installed into it. Where can I get stock firmware? Sorry I am really new to this stuff.

If you Google "xperia arc s 4.1.0.b.587 ftf" or something in Google you'll get results. The stock ROM is somewhere in the dev section too, use the search button, I'm on my new phone and search works weird here.
I assume since you unlocked BL you have drivers for your device.. In this case use flashtool, click on the lightning icon, navigate to your firmware file and connect phone in flash mode (menu + USB cable I think, I have not used my arc for some time but it should give you green LED if you done correctly), flashing will automatically start

Keep calm mate and you will sort it out.
use this thread for your stock ftf files and use the flashtool.
After that make sure you have got the correct kernel for the rom which you choose and always backup your system using recovery.
