[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.

[Q] Help with r800at

Hi everyone,
A friend of mine has had an Xperia Play on AT&T for a little over a year now. I've been flashing custom ROMs on Android devices since the OG Droid and the Nexus One all the way up until now on my Droid 2 Global (waiting for my Samsung Galaxy S3 to arrive). This friend got an HP TouchPad back during the firesale, and after seeing how nice CyanogenMod 9 is on it, he really wants a custom ROM on his Xperia Play.
The community at XDA is always very helpful, and I've searched around, but it seems the r800at owners are in the minority compared to the r800i owners.
I cannot seem to find a straightforward guide on how we would go about getting him started with this. I'm also unfamiliar with Sony's actual flashing tools, if they have any. Anyways, I've gathered the very first step would be to pay someone reputable on XDA to unlock the bootloader and Fastboot. This is required for the r800at, correct?
We've already gained root access on his device, and I have made sure he doesn't pull the latest update that AT&T is trying to push OTA.
Also, the r800at's hardware is identical to the r800i's correct? As in, after we get everything set up, he can just flash ROMs intended for the r800i, correct?
If anyone r800at can point me in the right direction as to how we would get his device up and running with custom ROMs, that would be extremely helpful.
Thanks in advance!

My signature says I have a r800i, but my phone was originally a r800at before I flashed it. Just an fyi.
Now, you're friend needs to unlock his bootloader/fastboot. He can just google search alessandro and you should come across his unlock bootloader site. Your friend has to pay him 24 dollars to unlock his phone. He does not make a profit whatsoever, the money is used on the program he uses to unlock the phone. Once that's done, if he goes to the CM page, he'll probably have to flash a different firmware, likely a r800i firmware. All he has to do is adjust his apn settings and it will be like nothings different. Just flash it via flashtool. Google is your friend. Since he's rooted, he should go to the market and install CWM auto installer. Then open the app and install CWM recovery. To access recovery, reboot your phone, and when the Sony Ericsson logo appears, continuously press volume down until you reach the menu. Now put that aside for a second. In the CM thread, there will probably be a zip file to be downloaded. Download it, and put it somewhere in your sd card. Do NOT unzip the file. Now boot into recovery. Using the volume keys to navigate, with the home key as select, navigate to install zip on sd card. Then locate it in your sd card and select it. Then select yes and let it do it's magic. This a very rough explanation so if you need more help just holler

I'm obviously familiar with using CWM, but I'm a bit confused- is it only the very first time you flash a ROM that it must be done through flashtool? Can we just use CWM to update/install new ROMs via the traditional method with zip files?
That's where I'm a bit lost- why and when must flashtool be used as opposed to CWM?
Thank you for the help though. I think first things first we'll get his bootloader and fastboot unlocked.

When you're flashing a rom, it may ask for a certain firmware since that might have been what the Ron might have been based off of. Once you have the required firmware, you can flash the zips away. Flashtool is used to flash the required firmware.

So when you say "firmware" are you referring to low-level stuff like the radio baseband?
If so, that makes sense.
So even the kernel can be flashed with CWM, correct?

[Q] Trying to install Xperia Play Z final version, very confused. (r800a)

Hey guys, as the post title says, I'm trying to install the xperia play z rom, and I'm hitting a lot of road blocks. First one is, I don't even know if my phone's bootloader is unlocked! I'm pretty sure it is, because I thought all r800a's came with an unlocked bootloader, and I also used the flashtool, unlock bootloader tool, and it said it was already unlocked.
So, naturally what I do, is I flash the firmware in the guide (located here - http://www.android-hilfe.de/root-cu...a-play/417392-rom-xperia-play-z-v1-1-0-a.html), and after that I want to root it so I can install a recovery. But when I try to root it, it always fails on part 1. So I tried to install cyanogenmod recovery without it. But after the apk is installed, i'm not able to install the actual recovery because it is not rooted.
My main problem with the guide is that it says to just boot into clockworkmod recovery, but I don't know how to. I turn on the phone and press the up button, but without installing the CWM/X-parts recovery, there's no way I can expect it to come up.
Any help please? I'm totally lost here. I know how to get roms that are based on gingerbread, but for some reason, Ics/Jellybean roms don't work at all, and I don't know if it is whether because my phones bootloader isn't unlocked (even though it says it is), or it's something else, like me missing a tutorial specifically for ics/jellybean roms.
Thanks in advance.

Well you have to flash an ICS kernel first and it will already have a cwm recovery in it. Then you can just boot to recovery and flash the rom

yes, boot.img is inside the zip. Unpack just that file and flash it with flashtool (in fastboot mode). But you must have unlocked bootloader to be able to flash any custom kernel

Sorry, another question. What happens is that when I try to flash an ics kernel, it goes into an infinite bootloop, but when I flash a gingerbread kernel, it works fine. Is this a sign of a locked bootloader? Cause I thought you wouldn't be able to install any kernels if it was locked.

If you flash ics kernel, you won't be able to boot your old gb rom. Ics kernel only boot into ics rom.
When you flash ics kernel, go to recovery and install ics rom.

Thank you so much. Worked like a charm.
For future readers -
a. The r800a indeed does come with bootloader unlocked
b. It is normal for the phone to bootloop, Just go into recovery like normal and install the rom .zip. (It's usually tapping back while starting the phone, but if that doesn't work, try up volume or down volume)

[Q] Can i keep going on r800x Bootloader Unlock?

// It seem that i posted on the wrong section (had alot of tabs opened, sorry for my mistake, if any admin can move the post, will be AWZUM!)

How ever that tutorial covers 2.3.3, and im running 2.3.2 Stock Rom, also when going to sonymobile and following the steps to unlock the bootloader, itsays to dial *#*#7378423#*#* and check for rooting status, my device dosnt have that displayed ( as a side note, i rooted my deviced almost 2 years ago).
However, I Continued with the sony steps and when dialing *#06# , the cellphone does give me my MEID, i continued with the tutorial, and so far, i got in my mail, my key to unlock my bootloader.
My question is, can i proceed with unlocking my bootloader? i would like to install a custom kernel so i can overclock it, to play games a little more fluid, my current room its a Stock Rom, however ALL the bloatware apps are gone now, my phone just have about 12 apps, and its using 80 megas out of the 300 the xperia has. is this good or i can go better with a custom kernel and a smaller rom?also im from mexico, when doing this im gonna need to reactivate my cellphone or something on the company?

You can unlock your bootloader with flashtool. Doublecheck your unlock code you got from Sony. Make sure you have correct drivers installed. Verizon kept the root status in service menu hidden... But it will work.

Yes it will work but as lordomn said check and make sure all your drivers are good then do it and you should be fine

Yeah, thats easy saying lo, but im particulari new to this.. theres alot of stuff involved, for example, im on 2.3.2 stock rom, i made a revocery image using CWM, and saved it somewhere safe, so here are the questions in order, ( if you can answer them in order would be great ):
1.- im on 2.3.2 stock rom, and i saw a kernel named 2.3.3 stock kernel with overclock, can i flash this with my stock rom and keep my stock rom, or i would need to flash first a 2.3.3 stock rom?
2.- when i want to test a new rom, do i need to flash the kernel first, or the rom?
3.- am i totaly safe with CWM and a nandroid backup?
4.- testing kernel is something safe? i mean can i go back?
5.- if something goes REALLY WRONG, can i flash the stock rom/kernel using flashtool?
6.- i found this http://forum.xda-developers.com/showthread.php?t=1605631 wich is the stock kernel 2.3.3 overclocked, but im on 2.3.2, can i flash it and stay on 2.3.2 or i need to flash the kernel and then the room, or first the rom and then the kernel?
7.- can i install CWM recovery on all the roms? i pretty much want to be safe, in case something goes wrong, or can i just use FLASHTOOL, to flash the stock firmware / kernel 2.3.2 and start over again?
8.- unlocking bootloader makes the xperia play able to use the flashtool, right? like, whitout unlocked bootloader, how does people flash roms for locked bootladers? using CWM recovery menu, the update .zip function? im pretty confussed right here, like, i unlocked my bootloader, so, i can use flashtool right, thats what unlocking the bootloader its for?

i think you can find the answer to alot of your questions here at FMA's thread it has a very good Q&A.... but anyhow ill answer them to the best of my ability.
1. im not sure as i never messed around with GB but i believe that 2.3.3 kernel will work on 2.3.2, but why would you want to stay on 2.3.2 when 2.3.3 has better performance?
2. Yes always flash the kernel first then the rom.
3. A Nandroid backup does not back-up the kernel as the partion its on CWM cant see... so if you get a faulty kernel flash or you flash a wrong kernel just use flashtool to get a working one.
4.yes you can always go back from flashing a kernel and yes its pretty much safe.
5. yes you can always flash with flashtool unless for whatever reason you damage the bootloader or the Trim Area then you have to seek for more advanced methods to recover the phone, dont worry tho if you dont accept an official update after unlocking the bootloader you will be fine.
6.i would be safe and upgrade to 2.3.3 using a .ftf so that you dont have any headaches.
7. yes you can flash CWM on all roms, however CWM is not part of the rom but the kernel and almost every costom kernel already has a recovery.
8.no everyone can use flashtool, unlocked or not except r800at models, no thats not what flashtool is for, flashtool is built to flash .ftf files to Sony Ericsson phones, it also has other functions like unlocking a bootloader and other things
if you have other questions just ask and i will do my best to answer them...

[Q] xperia s Change OS to 4.4 cyanogenmod

Dear forumers.
I usually do not ask stupid questions as that, but there I am very very confused
I just want to install some new OS to my XPERIA S (LT26i). Now I have all stock cellphone conditions with original 4.0.4 Android version.
My wish is to have phone fastest as it can be and all stable. I have read many many topics and guides there but I am still confused where to start. I need all flashtool, bootloader unlock, root, recovery, flash kernel, flash rom and do not know what to do first, second, third,... And I do not want to break up phone.
Can someone please kindly understand me and copy links of actual guides in right order? I need suggestions for 4.4 version OS-s too.
Best regards

Is it? If I go to Update Center or on PC in Companion it says me that phone is up to date. It cant find any updates. I don't know why?

Can someone just tell me where I must begin, and what to do next, and what is the last thing to do? (guess flash new rom)
I just need order of work from all stock phone. I understend the guides and I can find them, but do not know what is the right order.
Probably you don't know that it is not so easy to first doing that, but for noobs that forum is so hard to understand especially because of risk to damage your phone is something goes wrong.
Pleeeeeeeeeease

Hello Franklin.
I have just unlocked bootloader on my phone.
What I have to do next? Root, kernel flash, recovery?

Now you need to download a rom from the development section, then open the zip on your pc, extract the boot.img. Then copy the rom zip file on to your phone and flash the boot.img using fastboot or Flashtool. Then turn on your phone, and keep on pressing the volume up button to enter recovery. Then wipe everything except system and sdcard and then flash the rom.zip. Reboot your phone and it should be running kitkat

i tried many aosp was best but lack of customization killed me,but smoothness was real awesome the guy helped u is the developer of carbon rom but i didnt try it so no comments.for daily driver and gaming i wont recommend rayman's rom or pureslim.no offence,they are stable but comparitively few games were slow and dint start on both like subway surfers and fifa 14 :silly:

I have installed this on my xperia but it's not that it has to be. It's version 4.6 not 4.8 and it's not 4.4 kitkat bur 4.1.2 JB. OTA updater says: Error fetching update info: Invalid ROM (LeOpArDx) & device (lt26ii) combo!
And device is LT26i not ii. At 60 page of discussion the others have the same problem with version and updating.

download another rom from the xperia s development section that says specificly lt26i or xperia s or nozomi, version 4.4.2 or cm-11.0 and copy it onto ur devices internal memory -reboot into recovery (boot button+vol up hold until blue led) and flash ur new rom thats in ur internal memory. wipe dalvik+cahce and boot to system - u should be golden now :good:
