[Q] How do I flash a custom kernel & is it safe?

Basically the title says it all. I'm a noob at these things and don't wanna risk bricking my phone. I want to try flashing a custom kernel that will allow me to overclock my Play but I don't know how to..
My Xperia Play is rooted and has unlocked boot loader already and below are the things shown under 'About Phone'
- R800i
- Android 2.3.4
- 4.0.2.A.0.69

The most popular kernel for xperia play is doomkernel, i have also tried it it's very good. There is an description in the doomkernel thread how to install it.

It's pretty safe if done right, I was in the exact same position you were up until a few days ago, I spent a good few hours reading and I was running DoomKernel with Gin2ICS, clocked at 1.8. Now I'm just wanting to put that superchargev6 script on

Many people chose to do it the hard way. But teh best way it to use Flashtool

It's pretty much staright forward. Download your desired kernal and ofcourse after installing the programm head over to it's directory files and inside the drivers folder. Run the application "Flashtool-drivers.exe" and go on and install everything. (can take a long time). Then after run the programm without your phone hooked up with USB debugging on click on the flash icon (the first option from left) chose fastboot mode. Click on Reboot into fastboot mode via ADB. Then press "Select Kernal to Flash" and chose the desired kernal you have downloaded and after a couple of seconds you are good to go. Good luck!

Doom Kernal is the one of the best one out that and the chances of you bricking it is really very low

Will the "DoomKernel" kernel work on a .69 build? I checked out the thread and it only says for .42/.58/.62 FW.
Also, can I flash this without a custom ROM as well? I'm not really big into custom ROMS but I do need an extra dose of speed, hence the need for overclocking.

It will work on .69 and the kernel works with all stock roms.

If it's not too much trouble can you explain more clearly? I have already downloaded the doomkernel files(PLAY-GSM-DooMKernel-v14_boot.img) and the wi-fi modules from the other thread and I'm not quite sure what to do with it. Do I put the .img file into the Flashtool folder?
Sorry, but I really am a noob at these things.

Sorry i have tiped the wrong key
So activate debug modus under development section in apps section, then turn your phone off.
Then hold the search button of your phone and connect it to your pc. A blue light will light up, when that happens you can stop pressing the search button. Then tipe on the lightning symbol in fastboot and select fastboot. Then there will pop up a window, there you have to select flash kernel now you have to select the kernel file and press ok. It will begin flashing. When the progress ends you can turn on your phone. And don't forget to flash the wifi fix in recovery. I hope you are able to follow

Hey guys
I'm having an issue with flashing a kernal to my phone. I have a SE Xperia Play R800i GSM with stock GB 2.3. The phone is rooted and has CWM, but the bootloader is not unlocked. I have downloaded the flashtool and tried flashing my device to load the LuPuS kernel for the ICS4.0.4 ROM, but just cant seem to get any joy. The software recognises the device is rooted, but fails with each attempt to load the custom kernel saying it is because the device is not rooted.
Oh, in MSC with debugging available. I have attached a log from the flashtool software. Can anyone tell me where I am going wrong?
Thanks!

I believe you are required to unlock your bootloader in order to flash a kernel.

Please help! Xperia Play R800x VERIZON!

Hi I'm new here, just made an account 5 minutes ago.
I need help with getting CM7, CM9 or any other Custom Rom on my Xperia Play R800X VERIZON. I am Rooted, and have an Unlocked Bootloader. I was able to flash a UK version of the Xperia Play android version 2.3.3 Rom to make sure my bootloader was unlocked. The UK version was nice but it wasn't for me.
Just trying to get CM9 on my phone! but for some reason I'm having a really hard time doing so.
If anyone can help me or give me advice it would be much appreciated, I'm just trying to make use of my unlocked Bootloader! D:

Thanks for the reply!
Is there a "best" if you will, ROM or Kernel for the Xperia Play? I'm just trying to get the most out of my device. Also how do I get the gapps you mentioned?
I've done this a few times already but the main problem for me is: I get the kernel working, get into recovery, but when I got to apply/ flash the ROM I always seem to get and error message of some sort. Its very aggravating. I've been checking all over the internet for a solution but nothing so far, I've been awake for almost 48 hours now looking for a solution -.-
Thanks

For some reason when I use Flashtool to flash a kernel it ends up giving me an error message & then makes my phone inactive, I then have to flash back to VERIZON stock Rom all over again. Any ideas??

I appreciate all the replies!
But for some reason NONE of this is working for me :/
I can flash a stock ftf file via flashtool no problem. I can enter recovery via X-parts app no problem. But when it comes to flashing the kernel via flashtool & unzipping the rom file via recovery they always report back an error message which leaves my phone completely useless or stuck on a boot loop which I then have to re flash stock rom to have a working phone again.
Hopefully that made sense lol, I have TeamViewer if anyone can help me thru that possibly idk I'm out of ideas...

To flash kernels, I use Fastboot instead of FlashTool. If course if you choose that route, you'll need to set up Fastboot.

Haha right. Just use that link to find where it tells you how to setup Fastboot. The files and drivers are available to download from MediaFire. Just look for the clickable links on that page.

Did you get the files downloaded? If so place them in a folder on your PC together.
Power your phone off. Then power on while holding the search button. You should see the blue LED on top of your phone which means you are in Fastboot mode.
Try that much and report back, then we can work on actually flashing the kernel.

Go to the folder where you put the Fastboot and driver files. On your PC, hold in shift and then right click. You should see the option to open a command prompt here. Try that.

Can I Root without any computer connection.

I DO NOT want to use my computer with any command stuff.
My bootloader is unlocked and i have stock recovery.
I tried with all the driver stuff very very confusing. My phone is not even showing up anymore on my computer.
(TOO complicated)
Why can't i just do the same thing with other Samsung Phones-Drag root into system storage then just flash.Easy.

why did they make it sooo hard

In your case I would say just go get a toolkit and use that. There is no way, where you are at, to root your device. You NEED to flash a custom recovery which cannot be done on anything other than a computer to root your device.
Go here: http://forum.xda-developers.com/showthread.php?t=1614827
The toolkit includes device drivers and will do basically anything you need it to do.

It's really not that hard, actually only a couple commands and pushing some buttons on your phone.
*Plug In Phone*
adb reboot bootloader
fastboot oem unlock
*Volume up* *Power Button*
adb reboot bootloader
fastboot flash recovery Recovery.img
*Volume Down* *Volume Down* *Power Button*
Install Zip from SD Card - SuperSU.zip.
Reboot.
Done. Takes at most 10 minutes.

Odin isn't used on Nexus devices (as far as I know.) They use the Android standard, which is fastboot.
fastboot oem unlock
That's the command to unlock your bootloader. Be aware, it'll wipe your phone (security measure.)

ODIN actually is built into the device, but I think is actually more complicated than just using fastboot.

If that's all you want to do is root & leave your device on stock you can just temporarily boot a custom recovery & flash the super user.

All of my posted recoveries work fine. You didn't follow the directions close enough. Make sure you flash the universal root.zip once you get the recovery working. If not, it will re-install the stock recovery automatically.

Please explain how you are trying to add TWRP or CWM to your device. Do not leave out any details. This what we can see if you are missing a step. It should be a very simple process if the steps are followed correctly (as mentioned above). So please explain how you are doing it and what tools you are using.

I think step 7 is where you might be going wrong. Again, I THINK, I could be mistaken. But I would say start the tablet in normal mode before attempting to go into recovery. After the tablet starts, go ahead and shut it down. Then try and go into recovery mode.
Also, did you start Odin as an administrator? It sounds like you are OK in that regard as you got it going and loading. But if you are still having problems then try executing Odin as administrator.
Which .tar file are you loading? Is it one of the recovery files such as TWRP or CWM?
The only other thing might be the version of recovery you are trying to load. Make sure it works with your tab and firmware. I am sure you have already checked that, but just in case you forgot.

In your number 7, you should be holding volume up to get into recovery. When you see the Tab 3 logo, release the power button but continue holding home and volume up until you get into recovery.

I RECENTLY UPDATED MY LG G3 TO LOLLIPOP 5.0 AND I CANT OPEN SUPER SU, I TRIED DOING ABOUT 5 DIFFERENT THINGS TO UNROOT MY PHONE... WHEN I DO THE PROCESS WHERE I PLUG USB INTO COMPUTER AND HOLD THE VOLUME DOWN WHILE PLUGGING IT IN, THE PHONE WONT DOWNLOAD IT STAYS AT 0%. .. THE LG FLASH TOOL I CANT DOWNLOAD. IT KEEPS BRINGING UP ERRORS.. I TRIED DOWNLOADING FROM 3 DIFFERENT PLACES... I JUST WANT TO GET BACK TO MY STOCK PHONE....
After trying all of that to remove the issue when launching SuperSU "There is no SU BINARY installed, and SuperSU cannot install it. This is a problem! If you just upgraded to Android 4.3, you need to manually re-root - consult the relevant forums for your device!", it still isn't resolved.
Any help?
THANK YOU IN ADVANCE..

Well there is a lot of ways to restore back to stock just follow this thread. Best method is the KDZ or flash a restore zip via TWRP

Make Sure the LG Usb drivers are installed. Then The phone must be off. After that hold the Volume Up button, plug in the usb cable to the computer while holding the volume up button. Let go only when you see the screen get to the download mode. Only then can you use the LG Flash tool for KDZ

That is exactly what I did when I plug in my phone it shows the download mode icons in the middle for about 0.3 sec and goes straight to the "fastboot mode started" with the whole screen black. it does it very fast it doesn't go to the downloading firmware part

If download mode doesn't work you need to push these files fastboot with adb commands. Go to THEPagel's thread with all the stock zips and extract those out and push each and every individual files via fastboot. Remember you need fastboot and adb installed on your computer before proceeding. If you are new to fastboot and adb then suggest searching for a tutorial on that before even attempting this.

why don't you just flash a stock 5.0 lollipop rom that isn't rooted. Don't flash su and then you'll have a stock rom without root and twrp.

My intention is to have a stock ROM without TWRP so I can return it. Do you think that would work?

like I said in my other post. Download a stock 5.0 lollipop rom. After your done flashing don't flash twrp. It's going to ask you that you're not rooted and if you will like to root. Press no then reboot. There you go back to stock without twrp and root.
ThePagel has an untouched stock rom

Thanks alot man I will try that later today thanks

thanks a lot man I will try that thanks again
