Noobie here. Have been searching the internet to find a sucessful way to root my Sony Xperia play r800i 2.3.4 build 4.0.2.A.0.79. So far I can't seem to find a solution that works (have followed a few walk throughs but none have worked). Can anyone help? ...please... I've been trying this for 4 months now!!!
Hey,
seems you need to flash an older firmware:
http://forum.xda-developers.com/showthread.php?t=2157425
(question 2)
the tutorials related should help!
Also, you might want to back up apps and things because flashing a firmware resets your device.

not necessarily.
i haven't tried this on the .79, but as it works for .69 it most likely works for it aswell.
take a look at this guide: http://forum.xda-developers.com/showthread.php?t=1299729
Yes but that's for unlocking the bootloader.
You can root anything after that, however if you don't want to do it then 62 is the limit, at least according to the stickied FAQ, which I'm assuming would have been updated had it not been the case, no?

afaik unlocking the bootloader is just for flashing a custom firmware (cm7 in that guide) and is not needed to get it rooted.
No, you can flash a firmware without unlocking. (firmware (like .79 or .62) =/= rom (like CM7) =/= kernel (Doom LuPus etc))
Honestly, it's all in the effing FAQ in post 2.
Unlocking voids your warranty but allows you to install custom kernels, which are pre-rooted. However it's not required if all you want is a root access to debloat your stock rom. In OP's case, he wants an older firmware to get root with superone click zergrush method (because he's above .62).
However it's true it's not needed to unlock the BL to get root in general, just if you want to root above .62 and don't want to downgrade (and are willing to void your warranty for it)
Note: flashing roms doesn't actually void your warranty seeing as you just have to factory reset before sending your phone to customer service if you ever need to. But you can't relock your bootloader, because you need a key from sony to do it, and so they keep a record of you voiding your warranty in the process.

If you want everything stock do next (this works, I have the 79 fw in my Xperia right now with stock ROM and Kernel):
1. With Flashtool, flash the 4.0.2.A.0.79 firmware (Don't close flashtool)
2. Disconnect the Xperia and connect it in Fastboot.
3. In flashtool go to mode selector and select Fastboot mode
4. Now go to "Select kernel to HotBoot"
5. Select the "recoveryPlay.img" that I put in the attachments. Wait for your phone to reboot into the recovery by itself, don't disconnect yet.
6. Now in the recovery select "Install zip from SD card" and flash the "RootXperia.zip" that I put in the attachments.
7. Restart and disconnect your phone. Now you should have the phone rooted.
Go to Google Play and update the superuser app. Then open Superuser and update the su binary.
If you have the bootloader unlocked you can flash any kernel (Lupus or Doomlord) and thats enough. That Kernels are rooted.

Hi there, I have unlocked the bootloader and followed what you have said (steps 1-7) and all seems fine. Went to google play and updated the superuser app. Opened superuser and tried to update the su binary and it says
Downloading manifest.....fail!
I purchased the SU update fixer via google play, and still it fails!!! What am I doing wrong? All I wanna do is delete sims and a couple of other pre-installed games to make room for games I wanna play. (guess I should have backed up my contact list before flashing the phone too!!! Doh)

In order for you to bring your phone to Fastboot mode, you need to switch it off completely, and connect it to your computer while you hold the SEARCH key. A BLUE light will be shining in the notification LED while you're in this mode.

Will this work on the r800x model as well? I tried the method " [HOW-TO][zergRush Root] Root w/ v2.2.x-2.3.x (NOT ICS 4.x or GB after 11/2011)" but it is GB after 11/2011 and did not work. If this wont work how else can I do this? I would also like to unlock the bootloader and install JellyBean for my son but I am not sure what really the disadvantages are of doing it. We just got the phone today and I havent never had Sony Phones.

If you are on r800x then you would have to downgrade to 2.3.3 before trying to root.

Hello,
I have a Xperia Play R800i SIM unlocked with unlocked bootloader, firmware 2.3.4, 4.0.2.A.0.62.
Can someone link me to a Step By Step tutorial on how to root this phone? I have read this:
"Just download recoveryPLAY.img (google it) and place it in androidSDk folder where the fastboot.exe is located. Switch on your phone using fastboot and enter the command fastboot boot recoveryPLAY.img. Also download the RootXperia.zip and flash it once you are in recovery. Later on If you want CWM (recovery) on your phone , you can follow this thread."
But I don't know what fastboot is. I only know that in order to enter in fastboot mode on the phone you need to press the search button when connecting it to the PC.
Can you help me? And btw, if I manage to root the phone, will it wipe all my apps a.k.a. phone data? And what about the SD Card?
Thank You
Can't root if the firmware is .62 or higher unless you install a prerooted kernel.

Thank you
Would there be any prob if I follow the tutorial to install the "Xperia NXT v1.1" Rom?
To flash a prerooted kernel you have to have an unlocked bootloader. The just follow the install guide for which ever kernel you install once you get your bootloader unlocked.
I was able to root mine without unlocking the bootloader. Search and try this pc software which is quite easy and efficient... Unlock root v 2.3.1.exe download at unlockroot.com. Hope this helps

I couldn't use that software because my r800i was .62. But I managed to flash a new room and install a new kernel. Thanks anyway.
Hi all,
I have Arc S with Stock ICS, Unlocked boot-loader and relocked again with a tool I found on this forum. Root access using this tutorial: androidauthority.com/xperia-arc-s-lt18i-root-bootloader-unlock-custom-recovery-76876/
My problem is: I used Titanium Backup to freeze Track ID system app. After this my phone just won´t boot and get stuck on Xperia logo screen. I have CMW installed and I can boot on It using Menu Key + Vol Down. But I don't know what to do to repair my phone.
Can you guide me?
As you can see, I'm new here so don't be afraid of using a lot of details and I will appreciate.

Tanks for the response but I will need more details since I'm totally new at this. A quick search on Google send me to a lot of tutorials but I have some questions and don't want to render my phone useless.
My model is a LT18a and all references on tutorials are for model LT18i. Also, is It possible to find a stock 4.0.3 (4.1.A.0.562) stock rom to install?
If someone send me the Track ID System APK I can put it on the SD Card and try to reinstall it with CMW. Do you think this would work?
when you unlock your bootloader, u lose the DRM keys that can ever be regained.hence no use installing track id once again.now, you need to use flashtool to flash a custom firmware.for that,
1) download flashtool from here and install it and update it to the latest version
2) now download the compatible firmware from the given link and download it
3) now go to flashtool and on the left top side, you will find an icon with a lightning strike on it. hit that
4) click on flashmode and then follow the onscreen instructions.
5) now enter the flashmode (will be shown on screen)
6) wait for the flashing to complete and now reboot.

Use Flashtool repeatedly.. doesn't always work the first time around..
Does the LED indicator change after a while of being plugged in in flash mode? Check this, as I kept having the same issue. I just kept yanking the cable out and plugging it back in and repeating the procedure over and over until it fianlly flashed the kernel for me.
Was using arcknight kernel when i got stuck in bootloop, flashed to stock kernel and repaired over SEUS before unlocking BL and rooting once again using zergrush

The problem is, I used to have root and CWM installed, but now I can't enter it, because when I flash the ROM, it gets stuck in certain moment. I'm stuck somewhere between 3 and 4 point, where my flashtool doesn't correctly flash the ROM onto my Lt15i. From this bootloop I can't reach CWM or normal system to enter the google play or something.
I'll keep on trying flashing it, I'll also try to flash it from another computer
Is it possible that flashtool is being blocked by certain application like, I don't know, PC companion?
Additionally, I can't go back to the stock ROM via PC companion or SEUS, because when I'm in flashmode and phone is ready to flash, the PC companion says that my phone is already upgraded and there are no new updates to it, so it can't be upgraded, even tho there is some old flashed ROM inside ( I think PC companion reads the old ROM, that I used to have before bootloop, I believe it was the 4.0~~~~.62 version)

You don't need to install superuser.zip. TWRP has a builtin rooting function.
After going to recovery for the first time and when you reboot, it will install su & superuser.

Hello
As an initial note, I am not at all a techie guy. But I wanted to load Jelly Bean on to my Xperia Arc S. So I tried the following which I believe I should not have tried.
1. Rooted the device using ERoot 1.2
2.Unloaked the bootloader by following the steps described in sony website
3. Tried to flash Kernel using flashtool (latest from flashtool website) but was unsuccessful. It always says you need to root the device to flash in the activity log. But when I come out of fastboot mode, the flash tool always says the deice connected and it says the devise is rooted. But it never permits to flash the kernel in fastboot mode. I tried with different kernels, but unsuccessful.
4. So out of curiosity, I just decided to proceed with installation of jelly bean based on cynagenmod 10. So downloaded the Jelly bean ROM & doodle apps and copied to sd card.
5. I installed the CWM using x tool from play store.
6. opened the recovery mode and deleted all cache and other thing as per a video in you tube. Then proceeded with the installation of Jelly Bean and google apps. Installation was successful.
7. But when I restarted the phone, it just shows sony logo and hangs. It never starts.
8. After this I tried to flash a kernel again, it still says the devise is not rooted.
9. After reading few forum threads I decided to relock the bootloader and use pc companion to reload ICS or GB. I flashed a bootloader locker ftf file and was successful.
Now my phone is still showing only sony logo while boots and nothing. The PC companion is not detecting. Am stuck now. I don't know what to do. Please help. I donno if I did something wrong and l will have to discard my phone.
It's not the end of the world.

"Device must be rooted" error means bootloader is not unlocked. Check over, if you unlocked it properly, got all the codes correct etc.

There is no need for that. Custom kernels include Recovery already.

The issue there, is that this ROM and kernel do not work together in combination. ICS kernel must go with ICS ROM, GB with GB etc. Kernel was not installed, thereby you were with JB ROM, but ICS kernel (Sony logo).

Locking bootloader didn't change anything. You have to restore your phone to full stock ICS with Flashtool. Download complete ICS firmware FTF file and flash it with Flashtool.

Did you follow all the steps correctly? Because the next step says....

Hey, Thanks for the reply.
I understand I need to restore ICS and ICS kernel completely. But for some reason I cant flash using the flash tool as it says the device is not rooted. But honestly I have rooted the device using ERoot and have unlocked the bootloader. I believe that is the reason why I was able to install the JB ROM.
Now I have 2 problem in front of me.
1. I cant flash as it says the device is not rooted
2. I have relocked the bootloader
what's next??
Flashtool does not need root or anything to flash ICS. You are doing something wrong then.
You have to flash whole FTF file in Flashmode. If you occur any error messages, post them here.
i had the same issue

Hello
As an initial note, I am not at all a techie guy. But I wanted to load Jelly Bean on to my Xperia Arc S. So I tried the following which I believe I should not have tried.
1. Rooted the device using ERoot 1.2
2.Unloaked the bootloader by following the steps described in sony website
3. Tried to flash Kernel using flashtool (latest from flashtool website) but was unsuccessful. It always says you need to root the device to flash in the activity log. But when I come out of fastboot mode, the flash tool always says the deice connected and it says the devise is rooted. But it never permits to flash the kernel in fastboot mode. I tried with different kernels, but unsuccessful.
4. So out of curiosity, I just decided to proceed with installation of jelly bean based on cynagenmod 10. So downloaded the Jelly bean ROM & doodle apps and copied to sd card.
5. I installed the CWM using x tool from play store.
6. opened the recovery mode and deleted all cache and other thing as per a video in you tube. Then proceeded with the installation of Jelly Bean and google apps. Installation was successful.
7. But when I restarted the phone, it just shows sony logo and hangs. It never starts.
8. After this I tried to flash a kernel again, it still says the devise is not rooted.
9. After reading few forum threads I decided to relock the bootloader and use pc companion to reload ICS or GB. I flashed a bootloader locker ftf file and was successful.
Now my phone is still showing only sony logo while boots and nothing. The PC companion is not detecting. Am stuck now. I don't know what to do. Please help. I donno if I did something wrong and l will have to discard my phone.
