Please report if there is some issues with these kernel, I'm not a real kernel developers (just applying patches i think it doesn't count), I don't understand any C language, but I'll try to do my best to fixed it.
However I am NOT responsible if you damage your phone! please use it at your own risk!

How to Use it:

• make backup of your original wlan modules
• Put the downloaded wlan module (xxxxx_wlan_v3.zip) in your sdcard
• Power off the phone
• Connect the phone to the PC while pressing up volume to enter fastboot mode (the led is turning blue)
• Use Flashtool to flash the boot.img or using fastboot --> fastboot flash boot boot.img or if it doesn't do anything fastboot -i 0xfce flash boot boot.img
• Reboot the device
• Press continuously the volume down button to get in the recovery
• Choose install zip from sdcard; install xxxxx_wlan_v3.zip
• In CWM go to advance menu and do a dalvik cache wipe... (fist boot will take a minutes to 3 minutes longer because it will create a new dalvik cache)
• Reboot the phone

Zram is enabled in default setting., to disable it delete this file --> /system/etc/init.d/00zraminstall
to enable it again delete this file --> /system/zraminstall (v3) or /system/zraminstall2 (v4)

V4 Changelog

• fix bootloop in costum rom with built in recovery for locked bootloader
• disable 1,9ghz and 2ghz cpu freq... it causes random crash and not as stable as other freq so OC only enabled tp 1,8ghz
• Updated to 2.6.32.59
• Led notification light for entering the CWM
• New KGSL driver ported from 2.6.35 kernel [adridu59]
• Updated some android staging driver from 3.3/3.4-rc1 kernel git
• Updated zram driver, modified to use snappy compression instead of LZO
• Updated touchscreen driver from .74 kernel source
• Mount partition as noatime (kernel default) and set as non-rotational (using init.d script)
• Increase default minfree setting a little bit
• More and more changes can be seen at my github commit

V3 Changelog

• fix FM Radio bug
• Updated to 2.6.32.58
• Increase GPU memory to 4MB (before is 2MB) thanks to DooMLord

• Salvaged some RAM thanks to jerpelea
• Fix Ramdisk to install zram at default
• Remove some unnecessary driver
• Fix long startup at boot (please test it)

V2 Changelog:

• Rebranding it to X kernel
• Update cpu freq driver from Doomlord Github
• Update Patched Battery driver by Bazoocaze
• Expanding support to Mini, Mini Pro and Active (please be advised, I don't have the device so I can't test it, but I don't have any compiling problem Please report to me if any of you find one...)
• Remove NFS and CIFS support

KNOWN BUG:

• Compass may not working correctly in active... please report if there is any changes in the new kernel, I don't have the device to test it...

Source Code

I just open my GitHub account few days ago, I've upload the source there (I'm new at this, so the commit it a rather bit messy, but it contain my last source code)

here is the link:

bump... 297 views but nobody giving comment?
please do... even if you think it sucks...

I don't see files /system/etc/zram.sh and /system/etc/init.d/00zram, no zram device. I guess you push it in autoroot script in ramdisk and if device already rooted...

I've deleted /system/autorooted file and rebooted phone but no changes...

---------- Post added at 09:20 PM ---------- Previous post was at 09:19 PM ----------

Could you upload that scripts?

 

[Gustavo RD78]

Works great on my Xperia Mini!

As the above post, do not locate the files zram.

One thing I noticed is that using the kernel KRsH Rage or I get the warning for the latest update FW62 (I am in FW62), and using your do not have this problem, for this would be the last version?

Thank you!

 

[nimbold]

Thanks will flash it and response

I'll take another look at the ramdisk...
for the script you can use the zip files from this tread http://xdaforums.com/showthread.php?t=1207251
download the zram.zip from the attachment and flash it from CWM

the for now it will be the last version but if I have a bug fixed or an update, I'll post an update

Thanks will flash it and response

[Soulfly1976]

any improvement using zram?

 

[r33p]

any improvement using zram?

Creates RAM based block devices: /dev/zramX (X = 0, 1, ...). Pages written to these disks are compressed and stored in memory itself. These disks allow very fast I/O and compression provides good amounts of memory savings.

This kernel definitely looks promising.
Just flashed it and it is working good so far without any glitches.
Will give a feedback after I see how the battery life is doing.
Thanks for your contribution in the Xperia Lineup.

Best regards

Btw I am using a Xperia Mini Pro

 

[ajzak]

Flashed my mini this moment,
no problems so far
keep up the good work

 

[nimbold]

Flashed it and works great!
battery life is good i think. 2 hours in stand by and 1% drop.
5 hours display and wifi on and 30% yet remaining

but i have some problem with VPN which every time i try to connect via L2TP if display goes off, the phone will reset. but if i force screen been on (toching) it won't and connects successfully. don't know it's Kernel problem or not. but last kernel i used (KRsH) didn't have this problem.

Thanks in advance

 

[radmir]

I downloaded your kernel sources, /sbin/installzram.sh script just doesn't exist in ramdisk.

yes... I made a mistake after editing the ramdisk, it will be fixed after an update
meanwhile you can install this zram.zip from CWM...

It could be a kernel problem, there is a some compiling warning using gcc 4.6.3 one of them is a tunneling protocol, I've patched it so it doesn't gives warning (not as much as before) I'll going to take another look than at the script

I think i found the real issue. when wifi signal is weak (1 bar) the phone resets.

i dont hawe that problem! wifi is much beter than stock

 

[nimbold]

yeah, but i don't mean it.
when wifi signal is weak and i want to connect VPN using L2TP phone resets. without VPN in any signal strenght it's really good though.

 

[himasura]

I check it on Xperia Active - works faster than stock kernel.
But hangs from time to time when booting (50%/50%) on "SONY ERICSSON" appears.

May be it is because of new CPU frequency driver.

UPD: After few minutes of hour (don't know) the magnetic and orientation sensors are goes off until next reboot. It happend twice today.

Is there any free L2TP VPN service I could try? I google it but I can't find any free sites that doesn't need a credit card account

I'll try to test is some more and revert to the old cpuclock driver...
But I can't promise to post an update soon though... I get stuck on my job lately...
