Hi all,

if you don't mind, I'll bundle a few replies into one single post.

@Isander

I'm not really in love with Sony, but with my spouse and cat ;)

Fact is that I do think this set of phones are really awesome. We're moving out from "compact" phones to some smartphones looking more like a surf board than something that fits in the pocket. I personally don't need a 50inch TV in my pocket but a small phone able to do a lot of stuff and with a good battery life. Because it seems that this is not "trendy" anymore and even Sony is not making them anymore, I'm now have a full Xperia 2011 set and if one dies, might not able to buy a new one, I now have a couple backups for a very cheap price compared to when they first came out on the market. And m8 is for "mate", friend ;) Hope it wasn't too "familiar", no offence meant.

@BlackArtsInc

I'll do my best to have NOOP in V 1.4. This kernel has SIO which is based on NOOP and DEADLINE though.

Thanks for your suggestion.

@mp_ruda

That's a big dilemma that sometimes caused even wars between countries ;)

Jokes a part. This kernel has CWM 6.0.1.2 which doesn't have the Aroma half screen bug. I don't plan yet to move back to CWM5. I tried to have CWM touch included. Might need to move back to CWM5 if the android_secure issue proves to be linked to version 6. Latter versions are now updated only for JB.

@yamin8000

I plan on adding a way to customise these parameters via kamenu. Either in V1.4 or V1.5

I'll also check quickly why you can't modify ZRam size via script.

Didn't have much time yesterday to work on the android_secure backup issue or the offline charging one. But it's my top priority because without fixing these I can't move on. Today is Friday. Hopefully will have more time between today and the weekend to fix them and release a new version with some extra features. I still don't plan yet to issue two versions (CWM and TWRP). But who knows... Might find quickly the issues to those two bugs and be able to further move on. After all, once it's working, packaging one or two versions each time is no big deal...

Although, personally, I'd stick to CWM. Personally don't see any advantage with TWRP, considering some zips don't even work.

Take care you all, thanks a lot for your input!!!

what about usb otg

its now working for me after flashing this kernel

i enabled them from kamenu but no luck
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Hi,

when rebuilding the config I think I missed to add again CONFIG_USB_STORAGE and now our phones are not able to use a mass storage device, despite OTG is enabled.

Now... This said... Let me share some of the mistery related to the "offline charging" issue.

My main dev phone is a Mini Pro (Mango). On the 12th, when I released version 1.3a to fix Ext4, I build that version for all devices and flashed it to my Mini Pro, Mini and Active.

Despite the chargemon binary being the same, my Mini charges while off and displays the charging battery animation. My Mini Pro just reboots endlessly... Both run the same Rom. I even pushed Mini's copy of the chargemon to the Mini Pro, just to be sure it had not been corrupted on the Mini Pro.

This is very, very strange...

In case anybody has a spark of idea... Feel free to share it, I'm still digging...

Ka.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Happy to report that I found the reason for the offline charging reboots.

Best thing is that there is no need for an update on the code ;)

Out of curiosity, can the ones that reported the issue try on a main powered usb?

You mean AC Power Charger?

Sorry, but i can not to access it for a few days.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] mn31pro:

thanks
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] soracloudtidus:
i hope in the next version, the 3d performance will be better, i personally want for the performance will be better than the battery life, becaue you can always charge your battery, but you can't charge your performance ;)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] nagaya1:
Just saw the post I was busy these days,will test when I get some time :D

Thanks Ka for the USB serial :good:

USB Ethernet

Good news :victory:

I was able to compile kernel modules for my cheap USB Ethernet card and test it.

It's based on RD9700 chipset. See attachement for modules for kappa 1.6 :laugh:

It works well but had to use command line for setting up routing,dns...etc

Anyone knows good app to do this ?

Installation:

mount -o rw,remount /system

mkdir /system/modules

extract .ko files to /system/modules/

extract usbeth file to /system/etc/init.d/

chmod 755 /system/etc/init.d/usbeth

use ifconfig,route...etc commands to give ip,netmask,gateways ...etc

tried 1.7beta4 and black screen and high temperature, not boot, nothing show, must pull out battery. :crying:

Xperia Active with Revolution ICS HD 8.0

Flashed back to 1.6, work fine.

Tried 1.7beta4 on SK17i Mango. Video rendering seems to be worse than in 1.6 especially on youtube videos via the app, and I don't notice any other improvements whatsoever. Just giving some feedback about it, don't flame immediately... :)

Sent from my SK17i
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] karandpr:
On 1.7b4 and I have a weird bug...

The touchscreen becomes irresponsive slowly....starting from status bar and ending at somewhere in top 30% of touchscreen...( in less than 5 hours)

The problem is present in Zelly cream,nics and stock ics...

Not present if used Radeon or stock kernel...

And it is not present if I am using kappa plus Xperia active Rom(Zelly cream/Nics) on mini pro device...( touchscreen fix thread...)

In fact touch is much smoother...

Kappa is much more battery efficient than others by atleast 20%...

But touchscreen bug is driving me crazy....
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Let me check again the changelog. I'll upload soon another beta with a few things fixed and hopefully improved. Couple of changes in KaMenu too.

hello there, i'm confused how to enabled Kappa Menu?

When I turn on my phone with power and home menu about 3 seconds press, then it enter CWM.

I have no idea how to enter Kappa menu :confused:
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] andogeek10:
Download terminal emulator. Then give these commands - su

kamenu

After that you should be seeing the kappa menu. Just follow the step to get your desired settings.:)

hello, I have a problem when choosing SmartassH3 as cpu governor via KaMenu.

when I choose it (number 4), it will be automatically choose Smoothass.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] billyts14:
Unlocked and rooted that's why i can change my kernel any time but i solved the problem

The fastboot prob is because the usb port on my friends computer is 1.1 that's why no fastboot and now my headset prob gone after flashing mike's kernel and jellyvanillaex

Thanks for your concern

Now i'm using kappa 1.6 and hoping the best boot logo of sony or kast default cause sony is simple but elegant
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] zcedar:
where can i download the old versions of this kernel? tnx
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
You can imagine I do keep a link to older versions, for my personal "Kappa Museum" ;)

But I do keep in this post only a link to the most recent version, hopefully an improvement compared to the previous one.

So, just for curiosity, what version were you looking for, and why?

Hi,

what probs are you having with 1.6? Let me fix them, if I can...

Ka.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Saqib Nazm:
Hello kast, I wanted to inform you that some of the members said their battery gets stuck at 100% & never comes down. I don't know if that's a problem with only 1.7. If they re-flash the Rom the problem remains there. So must be not related to Rom. Can you check that on 1.7. Also I think when problem occurs if they change kernel it doesn't get solved. They had to change both Rom & kernel to solve the issue. I hope you solve this asap :good: good luck man
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Uhm... Really odd... I'm using 1.7 without probs... I can, unfortunately, guarantee that battery level goes down...

Especially considering that even changing kernel doesn't solve the issue... Strange that it's linked to the kernel...

Anyway, contacted that person directly to have more info. We'll see what it is related to. Thanks!

Ka.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Akshay Anand:
Bro if i remove battery and reinsert

Then it stuck at 100%

Nw using gb

No problems so faar :cool:
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Mysteryagr:
It happened to me too, battery stuck at 100% on version 1.7

my phone is xperia mini

Also I can't get root permission for link2SD.

I tested this kernel for a day then I switched back to cm10.1 due to issues.

Hope you can fix it, good luck ;)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
What kernel are you using with GB?

Ka.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] andogeek10:
I had faced the same problem. My battery got stuck at 100% for the whole day and stopped charging since the battery meter used to jump up to 100% from 0% the instant the charger was plugged in. Had the problem on ExMIUI and Smultronic. I haven't tried any other ICS rom so far with this beta 4 release.

Fixed it by installing Xkernel and wiping everything, including battery stats, and flashing Spartan Rom.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
We're at Beta8! ;)

Hi there,

since I'd like 1.7 to be a good one, decided to make a "clean start" by going back to 1.4 all the way up to 1.6 and then 1.7.

This allowed me to concentrate on what I consider really useful, leave behind some tons of patches that... Who knows, might have brought more trouble than fixes.

I'm now playing on my Mini Pro with 1.7Beta8, built from the 1.4 "ground" up. I did some benchmarks with Antutu Benchmark and it doesn't look too bad.

What are the big differences compared to previous versions?

I'll try to be brief:

First of all, as already wrote, we're starting from 1.4 again.

Contains updated GPU drivers, UKSM, Serial Drivers, general cleanups

new random generator (Havege) instead of Frandom. Seems quite good!

Adblocking is builtin (dnsd with custom hosts file) (Should speed up UI in general by pointing DNS queries to OpenDNS and use cache)

And this is only the big ones...

Yes, this version has a bultin adblocker. Your DNS queries will be routed to a micro "internal" dns server (busybox's dnsd) that is configured to block any connection to a known adserver. The blocklist can be updated via the Tweaks menu in KaMenu. Of course, this can be disabled too.

Queries that don't get blocked, are sent to OpenDNS which is much faster than any mobile provider DNS.

In this version a couple of annoying bugs related to poweroff issues are removed. Personally didn't have the battery issue either.

Looks a little faster to me... I'll post soon the images in case you want to try it.

Take care,

Ka.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Saqib Nazm:
Great News kast!!! So after flashing this kernel I think I will just delete Flashtool from my PC :p :p
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] rahimali:
Can you share smultron build please? Privately if you don't want it going public just yet ;)

Thanks a lot!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
And here we are...

Please, do consider these binaries as test versions...

Kappa 1.7 Beta9 for Mango / Mini Pro

Kappa 1.7 Beta9 for Smultron / Mini

Kappa 1.7 Beta9 for Satsuma / Active (Untested)

Kappa 1.7 Beta9 for Coconut / LWW

New default CPU Gov and IO Sched combo is: SmartassH3 and ROW

Adblocker and adblocker hosts update is bultin. Adblocking is enabled by default. Adblocking update is a manual operation in the Tweaks section of kamenu.

CPUFreq steps are now by smaller increments (100Mhz)

and much more... ;)

Thanks to anyone who dares trying them out!

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sravan242:
I consider to try it on my LWW!!

Edit:

1.Problem in first boot(we should reinsert battery to boot).

2.Problem in power off after the first boot...

3.It's not booting in second boot.. its struck at boot logo.

For now that's it, because to test more things it should boot but it isn't booting. i am reverting to V1.4

Seems like I spoke too soon. :( Even my battery is now stuck at 100%. I just changed my kernel to rage and all is fine for now.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Again, very odd. My battery goes down "just fine", never seen it stuck at 100%.

Is it just after charging it to 100% or it just pretends to be at 100%?

Can you tell me again what rom you're using? I need to test with it.

Ka.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Which Rom are you using?

Ka.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] andogeek10:
I was using my phone normally (music and whatsapp) and suddenly one two apps froze and force closed. So I just rebooted my device and it got stuck on the shutdown animation. So I did a battery pull out and then it restarted. When it booted up my battery was stuck at 100%.

If it gets discharged completely then it just shutdown automatically. After plugging in my charger the battery is on 1-2% for a minute and then it jumps back to 100%, thus not allowing the battery to charge at all.

I changed my kernel (to Rage Kernel) and that fixed the issue.

I'm on ExMIUI.

Thanks for your quick reply.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] avirale123:

Battery

Hi Kast,

Don't know whether it helps you or not... even I'm having this battery issue..

thing i did is

i was using Xnxt Rom with your 1.7 beta1 kernel and i dint had any issues with battery thing.

later i flashed stock rom and before booting rom i flashed your kernel 1.7 beta1 and flashed Saqib's Flourscent rom and i got this battery prob.

i tried to change the kernel to panic and same thing followed and now im on Lupus kernel v6 with no issues.

PS: I tried ur 1.7 beta9 and in cwm recovery while doing factory reset it gets stuck at formatting Sd-ext. i have ext4.

Now im flashing your kernel again and checking.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] XenderX666:
Hi [MENTION=373657]kast[/MENTION] ,

still no resolution to the problem of battery?

thx.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
I don't have that issue, which doesn't help trying to solve it.

Believe me that I'm trying to understand what is happening.

Up to now, this is what I understood. Please, all of you, correct me if I'm wrong.

People using 1.6 never had the battery stuck at 100% issue.

People trying beta 1.7 Beta4 started, some of them, having the issue.

People that tried 1.7 Beta9, which starts back from 1.4 and includes some of the patches 1.7Beta4 included, still have the issue.

People that re-installed 1.6 after 1.7Beta still see the issue till they install a totally different kernel.

Replacing rom doesn't change anything.

Now... What could make such a problem stick between 1.7 and 1.6... Considering nobody ever had the issue with 1.6?

Why am I not having this problem? I use my Mini Pro with Fluorescent Feather rom. No battery issue.

There is absolutely no patch between 1.4 and 1.7Beta9 that touches any part of the battery or charging code. Makes it difficult to see what could cause such side-effect.

Not easy... But I'm trying.

Ka.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Doubtfire:
Sir, i hope i can help. I had the issue in battery staying at 100% when im on flourescent rom even in v1.6

What TRIGGER this bug, is when i remove the battery and reinsert it. After turning on the phone, 100% bug is there.

If you can try to remove your battery and turn on the phone, MAYBE it will happen to you also. Just my hypothesis. :confused:
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Removed battery at least 5-6 times, rebooted, still battery going down...

Now I'm going down too ;)

Really need to see the issue to be able to check what is going on...

Could somebody having the issue download a battery calibrator app from the store to see what it reports?

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Gustavo RD78:
good, my impressions are that this problem that some people have reported battery 100% is not kernel

this has NOT happened to me even once (stock rom)

this happens only with a rom, or other too?

There are several factors to be the cause of this problem, as SystemUI.apk, Framework-res.apk or even a file .jar
