gnufabio can you build last chocolate kernel? I think the new kernel contains many fixes.
And i have question, how i can build kernel from acer sourse but with mt fix? Thx!

I am using 4.005.05AAP_Gen2, and non of these OC kernels work well for me
all of them freezes after OC
Any help?

I use Acer Liquid S100, not Acer Liquid E Ferrari Edition. I use AcerFerrari as my username because I am a loyal Ferrari fans.

Sorry for my misleading~

Maybe you have overclocked the cpu too much, my A1 for example didn't support frequencies above 921mhz...
liquid e generally is better in overclock.

First flash the bin then flash the t&l and finally the kernel

hello and happy new year :)

well, i still have my liquid A1, with LCR-F 2.0 and bin 4.002.14.EMEA.GEN :)

i read this subject with attention
and also the subject below :
http://android.modac...acer-based-rom/

there has been a lot of collaborative work on the kernels, this is a pretty good thing of course, but as a consequence the features and status are a bit confusing :rolleyes:

with my rom LCR-F 2.0, what custom kernel shall i use ?

to summarize...
choco-acer-kernel-110527-1501 mentioned here, as some LCR-F 2.0 users seem happy with it,
or :
lcrf20_ritchen_921_v1 (http://android.modac...acer-based-rom/) ... 921 or any other speed !
or :
chocolate_fix3 (http://android.modac...res-working-xd/)
or :
oc_lcr_new (http://android.modac...acer-based-rom/)
or even :
oc_with_mt_new / oc_without_mt_new

i'm a bit lost...

what is unclear for me :
- i assume that the kernel with name containing LCR are optimised for LCR... so why using choco-acer-kernel-110527-1501 ? or oc_with_mt_new etc ?
- lcrf20_ritchen_921_v1 (though max speed is in file name, underclock is possible). despite its naming, this kernel is packed by fearfactor84
- ritchen oc_lcr_new seems is less recent (feb 2011) but setcpu works
-  chocolate_fix3 : still not clear if app2SD with malez recovery is OK

fixes :
- bug on mic input volume for recording can be solved with this patch http://www.fileserve.com/file/9CAkp2a thanks to paZirezz
- card mount issues can be solved by unchecking safe mount / unmount if you use swap file and not swap partition

thanks and regards,
ph.

"Cloning into acer_stock_kernel...
fatal: remote error:
  Could not find Repository gnufabio/acer_stock_kernel"

Link to manipulate-boot.zip file inside the kacer script is broken, too :(
