Root Xperia play .62 software

Hi I was just wondering if anyone had found a way of rooting the play with .62 software (software not firmware). Apparently it can't be done but I would really like to overclock the CPU and install apps that need root one being disable the Xperia als
Plus if I downgrade my software to rootable one will my baseband version stay the same cause I want to install ics

If you want to overclock you'll need to unlock your bootloader and flash an overclockable kernel, like Doomlord's. This will also root your phone

flashing a custom kernel will only enable custom cpu speeds and will NOT root the software. (you are flashing the boot not the system) since root is controlled by the system partion changing the boot.img wont have much effect so having a kernel with overclock support on software that is not rooted is pretty pointless. i should know i build roms for the htc desire (search for tronicrom v2 htc desire if you dont believe me)

DooMLoRD's kernel does root the phone. Read his thread before posting

[Q] Kernel Flash

I have a GSM phone with stock 4.1.1 (with a latency patch).
My phone is unlocked, but not rooted.
I have CWM installed
If I installed a new Kernel my questions are:
1) Do I lose my data/apps and need to do a backup?
2) How do I go back to stock kernel?
Seems simple and probably answered before, but I was unable to find a thread that was simple and clear to follow.
Thanks

You'll need to get root privileges to flash and use a new kernel and be able to customize etc. You can flash a ROM with su binaries already installed or you can just do it manually. You don't need to wipe when flashing a kernel though. You should root though because not much reason to unlock bootloader and not gain root access.
Edit: once you gain root install titanium bu or another app to backup apps and data and you can get a flashable stock kernel from your device's dev forum. But you wont lose apps and data when flashing a kernel but I always make a nandroid in case something goes wrong.

1. you dont lose any data. just flash the kernel without wiping anything.
2. either flash the stock kernel/boot.img or reflash the stock rom.

you dont need root to flash anything if you have a custom recovery installed. that said, you will need root to use the apps that control the cpu speed/tweaks. you can always flash a kernel, boot it, and use it at its default settings without root.

Thank you I should have clarified that you could flash and use default settings. There's just no fun though in unlocking and installing a custom recovery if you aren't able to tweak and customize everything to tour liking

[Q]CWM + Root

Hi guys, so i have my stock Xperia Play GSM and i wanna install a custom Kernel with CWM and then root the phone using CWM. Can you please tell me what is the best Kernel for games and also has the CWM built in. Do i have to do anything else to my phone before i can do this ? I unlocked my bootloader and installed Flashtool ...
Device: Sony Ericsson Xperia Play R800i GSM, Android 2.3.4 -> 4.0.2.A.0.69
Thanks !

I can't tell you which is the best, and I hope all threads starting with "best" gets locked. But generally you need 2.3.3 to root but since you already have an unlocked bootloader, you can install any custom kernel, they have CWM installed so you can boot into recovery by pressing the Volume down button at Sony logo. From there you can install a custom rom that is already rooted. You need the rom and kernel to be compatible with each other in order for the phone to boot.
If you want to just root the phone you need to down grade to 2.3.3 and use the root feature in flashtool. If you want to manually install clock work mod, after rooting, use the CWM installer version 5 from this link, the option to reboot into CWM in the program will not work BTW, you'll have to do it manually. http://forum.xda-developers.com/showthread.php?t=1437840

If my bootloader would be locked, would flashtool work ? I wanna downgrade to 2.3.3 but when i do so, the program get's stuck at 17% ... When i flash the ROM, do i need to check/uncheck any items ? Like kernel or bootloader ?

The flashing process can take time, wait up to 10minutes. Sometimes it can get stuck due to bad cable or other variables. Try plugin it in a different port, preferably USB 2.0 port, and with no other USB devices connected to your computer, keep trying and it will work eventually. Try a different cable as well.
Flashtool have to work with locked bootloader, which is needed if you want to restore a locked phone to stock. You don't have to check anything unless you want to specifically exclude it from being flashes. You should flash this firmware, its 2.3.4 but it has been modified to be rootable: http://forum.xda-developers.com/showthread.php?t=1591398
I thought you said you unlocked your bootloader though.

[Q] Why do you need "unlocked bootloader"?

I've done some research in to unlocking the bootloader for my Xperia Arc. I have yet to understand the reason why you would need to unlock it at all.
The official definition given by Sony on their website is:
Unlocking the boot loader allows you to put custom ROMs on your device.
Click to expand...

However this is clearly not true. As I am able to put custom ROMs on my Xperia Arc without unlocking the bootloader (ie. I was on official ICS firmware. I flashed kernel to different version then root using doomlord's ICS root, flash back the original kernel then installing Ultimate HD 4.0 via recovery.)
I have noticed some other ROMs state they are for unlocked bootloader only. Is this becuase they require custom kernals in order to function? Is that why you need unlocked bootloader (because locked bootloaders can only accept official kernals during flash/boot)? Or is there a more in-depth reason?

To explain further, you can still install custom ROMs, but only ROMs based on stock firmware and using stock kernel. If you tried to install other ROMs like CyanogenMod you will realise that you can't install the ROM at all because you cannot flash the custom kernel that comes with it. What the unlocked bootloader does is allow you to install unsigned kernels onto your phone. Stock kernels are already signed by Sony so they can be flashed without unlocking your bootloader.
The kernels you have been flashing so far are all stock kernels so you can flash them with no issues. If you tried to flash a CM kernel you will get an error if your bootloader is locked.

Thanks. So I was right. The Kernel is (one of?) the reason you would want to unlock your bootloader.
Do you know if unlocked bootloader is required for SD partitioning on Xperia Arc? I had a read here http://forum.xda-developers.com/showthread.php?t=2126363 but something is confusing:
- Unlocked Bootloader (need EXT4 support, not allowed in stock kernel)
- EXT4 Kernel Support (most of kernels for Xperia 2011 have EXT4 support)

It says stock kernel doesn't work then says most Xperia 2011 kernel support it?!?!

It may refer to custom kernel for 2011 Xperia devices.

I see. So it's not possible to use link2sd without unlocked bootloader?

u dont really needed i payed 10 dollars to unlock it so i can use custom kernel to increase the performance of the phone,but still after 2 months after that i dont see any improvenments

Really? Went from Stock .587 rom to ultimate HD with stock .587 kernel and I find the phone can't handle more than 3 apps without slowing down at certain times.
I was actually considering unlocking so I can get an overclocked/custom kernel to improve performance.
What do you mean by after 2 months you don't see any improvements? Did the performance improve at first but now have gone back to similar performance of stock kernel?

If you don't know how to optimise the ROM then it will be as slow as any stock ROM. Don't say that the performance never improves after a certain time of usage. Please read up on the ways to optimize and improve ROM performance rather than assume that custom ROM is not good when you haven't tried optimizing it yet.

The base ROM is good, but it's the stock kernel giving the bad performance. Overclocking doesn't help much with performance so it's not recommended.
Like I said in my earlier reply, the ROM will work properly if you optimise it for performance, so don't say that the performance does not improve after a certain time of usage.

Correct me if I'm wrong but by saying "ROM will work properly if you optimise it for performance" do you mean flashing a custom kernel? (in which case you would need unlocked bootloader?)
Or do you mean an add-on like this: http://forum.xda-developers.com/showthread.php?t=1908269 ?
Or something else?

The only "optimizing" that u can do on a rom is removing the animations since overclocking is not recomenced.So i still find it useless.Even the phone app is starting slow.So in my opinion spenging money on unlocking ur bootloader is useless

So I tried "pimp my rom" and ticked all I thought I wanted but got a boot loop and had to reflash everything.
I'm keen to know what you mean by "optimising".

It can be as simple as installing and removing apps to running scripts that improve performance. I use Greenify to hibernate apps running in the background and I don't install Facebook on my phone. Only install apps that you use often because if you install many apps on your phone, it's going to take up more memory and slow it down.

2. Root and install CWM
3. Download the rom from downloads and put it on SD Card
4. Boot into recovery
5. Wipe Data/factory reset
6. Go to advanced-Wipe Dalvik Cache and go back
7. Go to Mounts and Storage-Format /System and go back
8. Flash the rom and device patch and wifi modules
9. Reboot and enjoy the Dual Core Xperia PLAY
I flashed stock, and rooted. my phone has locked bootloader.
Where can I find the right CWM? the market store and install directly from phone?
would appreciate some help. thanks. this forum has been so helpful.

I found this but I want to make sure.

locked bootloader
Am I underestanding correctly that you've got a custom kernel on a locked bootloader? (.58 enhanced)
I want to update to Android 4.x for some market apps that require it and can't seem to find guides. From what I have found it seems that the BL must be unlocked.
Any suggestions?

Stock .58 enhanced is Official firmware that is why you are able to install it with a Locked Bootloader. In order to be able to Flash a Costume Kernel(witch is needed for Android 4.1.2) you will need to Unlock your Bootloader.
