---[ UPDATES ]---

given away my Xperia Play to other devs... so friends as promised here i have given away my Xperia Play to @nickholtus & @Achotjan ...

I hope they will work on this device and continue developing for it... I am really sorry that I couldnt spend a lot of my time working on this amazing phone..


since I no longer have the device with me, I will not be continuing any development work on it and I am closing this kernel thread...


it was great working on this device and I will surely miss this phone and the great Xperia Play community which always supported me and my work!

I hope that I will meet some of you around on XDA in other device communities perhaps...


warm regards,

Rahul (a.k.a DooMLoRD)


---[ UPDATES ]---


Full touch recovery!!!




[ tips / recommendations ]


  1. for optimal results it is HIGHLY recommended to use -36 baseband with corresponding libs...

  2. for better battery life try undervolting... start off in steps of -25mV and see which is stable for u... for my PLAY -100mV was stable...

  3. before u report any battery drain issues please read this:
    [GUIDE] HOW-TO Properly Evaluate Battery Life and Provide Useful Reports



[ intro ]


hello ppl!

this kernel is for stock SE 4.0.2.A.0.42/.58/.62 FW...

for older kernel versions for older FW refer to following:
Older Releases [FW: 4.0.A.2.368]

details regarding recovery and how to enter recovery


[ how to install my kernel (v07 onwards) ]

  1. download the boot.img & wifi modules update.zip
  2. save the boot.img in the folder with fastboot binaries (fastboot.exe files)
  3. save the wifi modules update.zip to sdcard (on phone)
  4. power down device
  5. start device in fastboot mode
  6. use the following command to flash the boot.img
    Code:
    fastboot flash boot boot.img
  7. reboot phone and enter recovery
  8. flash the wifi modules update.zip for my kernel
  9. reboot phone and enjoy the kernel ;)


[ how to get back to stock kernel OR older versions of my kernel (v06 and lower) ]

  1. download the stock wifi modules update.zip
  2. extract the kernel.sin (or boot.img if u want to flash my older kernels) file from the stock FTF u used to flash this fimware
  3. save the kernel.sin (or boot.img if u want to flash my older kernels) in the folder with fastboot binaries (fastboot.exe files)
  4. save the wifi modules update.zip to sdcard (on phone)
  5. reboot phone and enter recovery
  6. flash the stock wifi modules update.zip
  7. power down device
  8. start device in fastboot mode
  9. use the following command to flash the kernel.sin (or boot.img if u want to flash my older kernels)
    Code:
    fastboot flash boot kernel.sin
  10. reboot phone and thats it u should now be on stock kernel (or my older kernel)



FOR OVERCLOCKING
  1. start SetCPU/NoFrills CPU Control app on ur Play (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
  2. now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
  3. DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
  4. SLOWLY increase the frequency one notch at a time and do stability/testing for few hours

[ for modders/themers/others ]

hey guys here i am attaching a template update.zip which has been tested to work on the recovery provided here... u can add ur stuff to that file and edit the updater-script so that the u can flash ur files via this recovery...
basically it contains the correct combination of update-binary & mounting syntax...

this file is NOT required for normal/general users

ALL CREDITS OF WORKING RECOVERY GO TO FREEXPERIA TEAM!

THANK YOU FREEXPERIA TEAM!!!

THANK YOU jerpelea (U KNOW WHY ;))!!!

THANK YOU Bin4ry (for the original RootXperia.zip file)


hello guys!

i am new to kernel development but i think this kernel would be useful for a lot of ppl using stock SE 2.3.3 FW...

i would like to thank Blagus, zdzihu and aZuZu for their help!

this is inspired from CF-Root for SGS2... thank u Chainfire for ur work!

i was requested by many ppl in this thread: [KERNEL][OC] Arc Stock O/C Kernel 1.86GHz For 3.0.1.A.0.145_146_148
to make a Overclocked (OC) kernel for Play.. so here it is with a few more goodies (insecure + prerooted + OC)...

thank you if2 for posting ur sources (for acpu file) and allowing me to work on it for Xperia Play! guys if u like this please dont forget to thank him!


thank you axiomjunglist & Quantuml3ap for testing this!

special thanks to axiomjunglist for helping out with beta-testing ;)

I AM NOT TO BE HELD RESPONSIBLE IF U DAMAGE UR PHONE / SPILL UR COFFEE / MISS UR ALARMS / ANY OTHER CALAMITY/MISHAP


[ wht is overclock? ]

"Overclocking is the process of running a computer component at a higher clock rate (more clock cycles per second) than it was designed for or was specified by the manufacturer, usually practiced by enthusiasts seeking an increase in the performance of their computers." - Source: Wikipedia

so it is pushing the boundaries posted by the manufacturers of the device to gain more performance!

BUT performance comes at a price! OVERCLOCKING can be and IS harmful to the device... prolonged use can cause hardware faults including the cpu chip getting fried!

ok time for some gyan!
  • see each cpu/chip is different
  • each is unique and has different tolerances
  • so dont directly jump to max frequency
  • slowly keep increasing the frequency
  • check its stability for 5-10 hrs
  • check for random reboots
  • check which one is best suitable for ur device
  • if u start getting reboots/OS freezes/device starts becoming too hot then throttle back and use lower frequencies
  • remember just because someone elses device was able to work at that frequency doesnt mean that ur phone can support/handle that frequency

YOU HAVE BEEN WARNED


[ wht is prerooted kernel? ]

well this kernel removes the security checks (atleast from ramdisk); su binary & superuser.apk will automatically be installed by kernel! no need to flash any additional zips or use one-click rooting apps! this kernel has it all in-build :D


[ features ]

  • prerooted
    • kernel is insecure (ro.secure=0)
    • su binary & superuser.apk will automatically be installed by kernel :D (thanks to Bin4ry for posting the file RootXperia.zip; i have used the superuser files from his zip)
    • busybox already installed in /sbin/
    • adb server is persistent
    • usb debugging enabled
    • rootfs and /system mounted as rw (thank you Blagus for the tip ;))
  • CWM recovery (Thanks to FreeXperia team)
    • ability to take backup/restore of ur ROM
    • flash any update.zips
    • lots more }:)
  • overclocking
    • set bootup frequencies from 245 Mhz to 1 Ghz
      so that ur device boots safely and u can use the kernel as is w/o overclocking
      for using the additional frequencies u will need a program like SetCPU
    • frequencies unlocked in kernel from 128 Mhz to 1.86 Ghz
      voltages for standard frequencies are stock, for nonstandard frequencies (1Ghz+) voltage has been increased
    • the frequencies are NOT UNDERVOLTED


[ requirements ]



[ screenshot ]

screenshot2zdusc.jpg


[ what have i done exactly? ]

  • compiled the kernel from stock SE sources with acpu file provided by if2
  • modified the stock ramdisk for this to function as per requirement
  • added Recovery files to ramdisk from ramdisk of boot.img from anzu_beta_FXP014 release
  • added su binary & Superuser.apk right inside kernel-ramdisk ;)


[ so why should u bother? ]

  • well now u wont need to download huge prerooted system.img files (150-250 MB files), u can just use download this small kernel (~6MB) which is prerooted with working recovery :)
  • overclocking will help the device perform faster in games/benchmarks (IT IS RECOMMENDED THAT U DO NOT OVERCLOCK UR DEVICE FOR A LONG TIME, throttle it back to stock frequencies once u finish ur "high performance requiring task" :p)


[ how to install ]

  1. download the boot.img
  2. save the boot.img in the folder with fastboot binaries (fastboot.exe files)
  3. power down device
  4. start device in fastboot mode
  5. use the following command to flash the boot.img
    Code:
    fastboot flash boot boot.img
  6. reboot phone and enjoy the kernel ;)
  7. FOR OVERCLOCKING
    1. start SetCPU app on ur Play (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
    2. now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
    3. DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
    4. SLOWLY increase the frequency one notch at a time and do stability/testing for few hours

if it get flashed properly and the device boots up check the Menu -> Settings -> About Phone -> Kernel Version
it should say something like the screenshot posted above... (thank you axiomjunglist for the screenshot)

thanks for testing!

i am slightly confused... did u test it on stock firmware or CM7?

also can u please post the About Phone screenshot (like the one i posted in 1st post) so that i can update 1st post with it!

thanks!

Stock firmware. I was on stock kernel with stock rom, bootloader unlocked, and rooted. Flashed the boot.img after making a recovery backup and was in business :)







Sorry for cruddy quality snap. Using an app called 'ShootMe'. Ironic name... what are you using for yours?

EDIT: Downloaded screenshot. Much better!

Does this break camera on stock rom like blagus his kernel?

In my experience with the cm7 kernel it's best to set it at 245MHz-1.4GHz if you like to run it conservative. Ondemand had the clockspeed nearly always on full speed, but with conservative lower then 245MHz makes the homescreen, app drawer, menu's etc. feel slower. With 245MHz this is much less. 1.5GHz made my device feel a little bit to warm while gaming for my taste, quickly resulting in sweaty fingers. Progbably because my case keeps it quite warm. 1.4GHz has this problem MUCH less in my case. I hope this helps.

Camera and wifi both working! Cheers DooMLoRD, this is a sweet kernel patch. I am really digging this. So far totally stable at 1516MHz... for now I will keep it there and run this overnight to get a true indication of stability.

Flashed the Kernel and can confirm axiomjunglist’s impression, everything works (Wifi, Camera etc.)

The first feeling about it was, that the touchscreen sensibility has noticeable increased, just as excepted.

I have tried to test out the 1.51 ghz frequency and I slipped accidentally to the max scale….lol.
It immediately crashed of course. Afterwards, I was able to run it stable at 1.51 ghz.

Well, I’m looking forward for the 1.86 ghz until the end of the week. But I will be definitely more careful now, with my clumsy finger ^^

Stable so far, will report back. Thank you deeply Doom & if2.

after testing ,, it work really good !!
I tested at 1516mhz and I got 2011 score at quadrant.
Will test more..

Edit: any frequency above 1.5mhz will crash the device and reboot. Maybe it just my device or maybe the cpu cant handle it anymore, but it seems very stable at 1.5

I got gutsy and ran the full 1.86GHz via SetCPU just to see what would happen. I did let my phone cool down for quite a while before attempting. I ran Quadrant and then my boot spontaneously rebooted by itself after quitting the app several minutes later. Temps also went up fairly quickly.

Surprisingly I've seen a broad range of results from Quadrant, ranging from 1650 up to a high of 1954 - all at 1.51GHz. At 1.86GHz I only scored a 1744 on the 1st run. 2nd run it scored 1727. Not sure why I haven't broken 2000 if others seem to be able to.

Decided not to get too cocky and ramped it back down to 1.51GHz, for now...

Maybe some other processes that are eating resources?

larsiano could you pls tell me how did you install the battery percentage mode?
i want this kernal badly but i really care about battery life,with stock kernal i must use a battery indicator which drains battery,but with percentage mode it doesnt, i am using v05 of frasertag but he is off the play and i love to keep my software developed and updated( it kills my rotien! and freshens my experiace) lool thanx in advanxe

i personally dont have a Xperia Play to test but from wht feeback i am getting seems the wifi & camera is working properly...

i can create an undervolted version of this same kernel which will basically eat lower battery (but then it might be unstable on some devices)...

    ---[ UPDATES ]---

    given away my Xperia Play to other devs... so friends as promised here i have given away my Xperia Play to @nickholtus & @Achotjan ...

    I hope they will work on this device and continue developing for it... I am really sorry that I couldnt spend a lot of my time working on this amazing phone..


    since I no longer have the device with me, I will not be continuing any development work on it and I am closing this kernel thread...


    it was great working on this device and I will surely miss this phone and the great Xperia Play community which always supported me and my work!

    I hope that I will meet some of you around on XDA in other device communities perhaps...


    warm regards,

    Rahul (a.k.a DooMLoRD)


    ---[ UPDATES ]---


    Full touch recovery!!!




    [ tips / recommendations ]


    1. for optimal results it is HIGHLY recommended to use -36 baseband with corresponding libs...

    2. for better battery life try undervolting... start off in steps of -25mV and see which is stable for u... for my PLAY -100mV was stable...

    3. before u report any battery drain issues please read this:
      [GUIDE] HOW-TO Properly Evaluate Battery Life and Provide Useful Reports



    [ intro ]


    hello ppl!

    this kernel is for stock SE 4.0.2.A.0.42/.58/.62 FW...

    • if u try to enable them on new kernel (v7 onwards) u will get "ERROR" while starting WIFI...
    • i will be providing wifi modules for my kernel which HAVE TO BE FLASHED VIA RECOVERY for wifi/bt to work correctly
    • stock wifi modules will also be provided which again will have to be flashed via recovery if u want to return to stock kernel OR if u revert to older v06 or lower kernels


    • remember i have already told this to u guys... if i see some users reporting that wifi is giving error because u did not follow my instructions ur post WILL BE IGNORED....

    [ requirements ]



    details regarding recovery and how to enter recovery


    [ how to install my kernel (v07 onwards) ]

    1. download the boot.img & wifi modules update.zip
    2. save the boot.img in the folder with fastboot binaries (fastboot.exe files)
    3. save the wifi modules update.zip to sdcard (on phone)
    4. power down device
    5. start device in fastboot mode
    6. use the following command to flash the boot.img
      Code:
      fastboot flash boot boot.img
    7. reboot phone and enter recovery
    8. flash the wifi modules update.zip for my kernel
    9. reboot phone and enjoy the kernel ;)


    [ how to get back to stock kernel OR older versions of my kernel (v06 and lower) ]

    1. download the stock wifi modules update.zip
    2. extract the kernel.sin (or boot.img if u want to flash my older kernels) file from the stock FTF u used to flash this fimware
    3. save the kernel.sin (or boot.img if u want to flash my older kernels) in the folder with fastboot binaries (fastboot.exe files)
    4. save the wifi modules update.zip to sdcard (on phone)
    5. reboot phone and enter recovery
    6. flash the stock wifi modules update.zip
    7. power down device
    8. start device in fastboot mode
    9. use the following command to flash the kernel.sin (or boot.img if u want to flash my older kernels)
      Code:
      fastboot flash boot kernel.sin
    10. reboot phone and thats it u should now be on stock kernel (or my older kernel)



    FOR OVERCLOCKING
    1. start SetCPU/NoFrills CPU Control app on ur Play (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
    2. now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
    3. DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
    4. SLOWLY increase the frequency one notch at a time and do stability/testing for few hours

    given away my Xperia Play to other devs... so friends as promised here i have given away my Xperia Play to @nickholtus & @Achotjan ...

    I hope they will work on this device and continue developing for it... I am really sorry that I couldnt spend a lot of my time working on this amazing phone..


    since I no longer have the device with me, I will not be continuing any development work on it and I am closing this kernel thread...


    it was great working on this device and I will surely miss this phone and the great Xperia Play community which always supported me and my work!

    I hope that I will meet some of you around on XDA in other device communities perhaps...


    warm regards,

    Rahul (a.k.a DooMLoRD)

    Doom lord has moved on to another device so no there haven't been any updates in a while and there won't be anymore

    Sent from my Nexus 10 using xda app-developers app

    oh there will be an update... just waiting for nAa to release the sources... then i will try n port the 3.0.8 kernel to the Play :)

    hello guys!

    i am new to kernel development but i think this kernel would be useful for a lot of ppl using stock SE 2.3.3 FW...

    i would like to thank Blagus, zdzihu and aZuZu for their help!

    this is inspired from CF-Root for SGS2... thank u Chainfire for ur work!

    i was requested by many ppl in this thread: [KERNEL][OC] Arc Stock O/C Kernel 1.86GHz For 3.0.1.A.0.145_146_148
    to make a Overclocked (OC) kernel for Play.. so here it is with a few more goodies (insecure + prerooted + OC)...

    thank you if2 for posting ur sources (for acpu file) and allowing me to work on it for Xperia Play! guys if u like this please dont forget to thank him!


    thank you axiomjunglist & Quantuml3ap for testing this!

    special thanks to axiomjunglist for helping out with beta-testing ;)

    [ wht is overclock? ]

    "Overclocking is the process of running a computer component at a higher clock rate (more clock cycles per second) than it was designed for or was specified by the manufacturer, usually practiced by enthusiasts seeking an increase in the performance of their computers." - Source: Wikipedia

    so it is pushing the boundaries posted by the manufacturers of the device to gain more performance!

    BUT performance comes at a price! OVERCLOCKING can be and IS harmful to the device... prolonged use can cause hardware faults including the cpu chip getting fried!

    ok time for some gyan!
    • see each cpu/chip is different
    • each is unique and has different tolerances
    • so dont directly jump to max frequency
    • slowly keep increasing the frequency
    • check its stability for 5-10 hrs
    • check for random reboots
    • check which one is best suitable for ur device
    • if u start getting reboots/OS freezes/device starts becoming too hot then throttle back and use lower frequencies
    • remember just because someone elses device was able to work at that frequency doesnt mean that ur phone can support/handle that frequency

    YOU HAVE BEEN WARNED


    [ wht is prerooted kernel? ]

    well this kernel removes the security checks (atleast from ramdisk); su binary & superuser.apk will automatically be installed by kernel! no need to flash any additional zips or use one-click rooting apps! this kernel has it all in-build :D


    [ features ]

    • prerooted
      • kernel is insecure (ro.secure=0)
      • su binary & superuser.apk will automatically be installed by kernel :D (thanks to Bin4ry for posting the file RootXperia.zip; i have used the superuser files from his zip)
      • busybox already installed in /sbin/
      • adb server is persistent
      • usb debugging enabled
      • rootfs and /system mounted as rw (thank you Blagus for the tip ;))
    • CWM recovery (Thanks to FreeXperia team)
      • ability to take backup/restore of ur ROM
      • flash any update.zips
      • lots more }:)
    • overclocking
      • set bootup frequencies from 245 Mhz to 1 Ghz
        so that ur device boots safely and u can use the kernel as is w/o overclocking
        for using the additional frequencies u will need a program like SetCPU
      • frequencies unlocked in kernel from 128 Mhz to 1.86 Ghz
        voltages for standard frequencies are stock, for nonstandard frequencies (1Ghz+) voltage has been increased
      • the frequencies are NOT UNDERVOLTED


    [ requirements ]



    [ screenshot ]

    screenshot2zdusc.jpg


    [ what have i done exactly? ]

    • compiled the kernel from stock SE sources with acpu file provided by if2
    • modified the stock ramdisk for this to function as per requirement
    • added Recovery files to ramdisk from ramdisk of boot.img from anzu_beta_FXP014 release
    • added su binary & Superuser.apk right inside kernel-ramdisk ;)


    [ so why should u bother? ]

    • well now u wont need to download huge prerooted system.img files (150-250 MB files), u can just use download this small kernel (~6MB) which is prerooted with working recovery :)
    • overclocking will help the device perform faster in games/benchmarks (IT IS RECOMMENDED THAT U DO NOT OVERCLOCK UR DEVICE FOR A LONG TIME, throttle it back to stock frequencies once u finish ur "high performance requiring task" :p)


    [ how to install ]

    1. download the boot.img
    2. save the boot.img in the folder with fastboot binaries (fastboot.exe files)
    3. power down device
    4. start device in fastboot mode
    5. use the following command to flash the boot.img
      Code:
      fastboot flash boot boot.img
    6. reboot phone and enjoy the kernel ;)
    7. FOR OVERCLOCKING
      1. start SetCPU app on ur Play (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
      2. now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
      3. DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
      4. SLOWLY increase the frequency one notch at a time and do stability/testing for few hours

    if it get flashed properly and the device boots up check the Menu -> Settings -> About Phone -> Kernel Version
    it should say something like the screenshot posted above... (thank you axiomjunglist for the screenshot)
