ALL CREDITS GO TO ZDZIHU FOR MAKING THIS NEW KERNEL WHICH WORKS ON LATEST BASEBAND



Use the following at your own risk and it's not supported by the rom dev (zdzihu / jerpelea / others)


if u are new to custom kernels please read this guide: [How-To] Testing or Using Custom Kernels on Xperia X10



If you were able to get it to work on the rom you use please mention the rom name/version number in your post so that it can help everyone... also please mention which specific boot.img you used + which wifi module worked for you (if u needed to use any additional patches)
Since there are so many roms and various versions it is difficult for ppl to test it out on each and every one of them...
Based on your feedback I will update second post with that info and link up to ur posts so others can be benefited from your experience....


Additional Info:
  • 20072011_failsafe kernel was posted by zdzihu on July 21, 2011 and is without undervolting/over/underclocking
  • 20072011 kernel was posted by zdzihu on July 20, 2011 and has interactive governor as default
  • 15072011 kernel beta was posted by zdzihu on July 15, 2011 it has interactive governor added and is undervolted, overclocked (245Mhz to 1113Mhz)
  • 14072011 kernel was posted by zdzihu on July 14, 2011 its undervolted, under+overclocked (128Mhz to 1113Mhz)
  • 05072011 kernel was posted by zdzihu on July 05, 2011 and is marked as STABLE version (NO overclock!)
  • 23062011 kernel was posted by zdzihu on June 23, 2011 [ its an alternative version to zKernel_22062011 for those with "random shutdown" issue ]
  • 22062011 kernel was posted by zdzihu on June 22, 2011
  • if u guys getting WLODs then try setting max cpu speed to 998Mhz
  • also wiping cache/dalvik-cache in recovery might solve some issues



[ FOR FROYO ]


[ FOR GB ]


as for other stuff i have tried to explain in post #2 wht kernel and ramdisks are...

all available stuff is provided for u to try... some kernel may work perfectly with ur X10 while other might not... u are free to try whichever u want and may be report back on which worked best for u... BTW the kernel which works best for u might not necessarily work properly for others...

some ppl who are having problems with FROYO version can try the boot.img from GB:

along with FROYO wifi module posted for that kernel versions


some info on wifi modules


[OPTIONAL] additional if u are still facing wifi issues u can use:
wifi_bt_fix-fxk_froyo_v01.1.zip : patch module from [PATCH] Fix WiFi and BT for FreeXperia Kernel (froyo) to use wifi/BT


some info on why there are so may boot.img files of the same kernel:

additionally some features like cpuscaling, wifi module setup (app2sd???) are introduced in enabled/set in ramdisk so thats why some ramdisk work for some ppl while for others it may not work...

ok firstly which kernel file u flashed? cause the wifi module depends on the kernel used...

FROYO (some GB roms too) required wifi module to be called wifi.ko and located at /system/lib/modules/

CM7 (may be all GB???) required wifi module to be called ar6000.ko and located at /system/lib/modules/

both are essentially the same files, just the file name is different (thanks to jerpelea for pointing that out)

(its wifi module for froyo for zkernel_22062011)

if required:

Isn't ar6000.ko only limited to Jerpelea's CM7 ? I am using rdannar's GB MIUI and had to use wifi.ko for wifi to work.
