Really odd... I don't see how changes that happened between 1.4 and 1.5 could affect radio signal.

As posted in first post, full changelog is visible at:

I was on 1.4 now flashed 1.5. So I am following your kernel :good:
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] himasura:
just tried to backup on v1.4 - same problem:

.android_secure filre size is 2.4K only!

Then tried on Radeon v4 kernel - file size is large.

Maybe it is a cpecific for CWM6 recovery?

If i try agan, did i kill my SD card again? :confused:

or maybe my SD card was damaged before recovery, and that happens... i dont't know, will try it again soon.

---------- Post added at 04:34 PM ---------- Previous post was at 03:53 PM ----------

OK now for those who don't want to loose .android_secure files in recovery (it happens when you change something in this files in current ROM, then recover back old ROM):

- boot in CWM

- go backup and restore -> choose backup format -> tar

- backup

That's why i love CWM5 :)

I have very good battery life. And, I don't know, maybe it's a "placebo effect", but that new LMK really works. Now I have more free ram. Before, after opening, closing, reopening apps, after a while I had only 60 mb ram free. Now I always have 90+. Maybe it's not him causing that, but I'm really happy.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Tried it on Smultron running 1.5. Indeed it doesn't work.

It says it backed up everything, including android_secure but when I restore the backup, it just hangs at boot when I reboot.

I'm gonna try with 1.3a

i need it for miui porting. think it same for all version of android right? really need it
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Offline charging will be fixed with next release. Just tested the fix and it works.

The standard chargemon provided by the rom for some reason doesn't work. Found one that works (sourced from Mesa kernel) and bundled it in my kernel. Now I don't rely anymore on /system/bin/chargemon but call the bundled one.

Still checking for the android_secure bug that prevents a good backup to be made.

R: [Kernel][ICS] Kappa Kernel 1.5 - Stock and Boost - 01/04/2013

I'm trying v1.5 with xNXT 8 and works pretty good.

I like weatley governor, it makes my phone faster and stabler.

Thank you.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
So...

Need your advice...

I took CWM 6.0.2.8 (which is for Jellybean) changed a couple linsof code to compile against ICS.

This version by default uses TAR instead of dedupe hence doesn't give issues like 6.0.1.2 where you have to choose TAR as a default method by yourself. Nevertheless, as of curiosity, tried to backup with dup and it's giving the same issues as the current bundled version in my kernel.

Now, 6.0.2.8, at least on my first test, probably because I missed something in the way, doesn't show the backup progress. Does backup but you don't see the filenames nor the progress bar. Not a show stopper but annoying.

Hence I think I'll switch the default backup method in 6.0.1.2 to TAR and maybe even remove the dup option as it doesn't seem to work properly.

Ka.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] himasura:
You sure that TAR backup on 6.0.1.2 working properly? Look in bacup folder:

.android_secure.vfat.tar.a size XXX Bytes

.android_secure.vfat.tar size 0 Bytes
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Got my little Mini, moved an app on SD (on the Mini didn't have any app on SD yet).

Patched 6.0.1.2 to use TAR by default

Ran a backup and restored it.

My Mini boots perfectly fine

And my SD app is still there.

I guess we can assume it is working, no?

Let me make a little more tests, like moving the backup to a fresh SD and restoring from there.

Your wish is my command

Backed-up my Mini via this "patched" 6.0.1.2 that uses TAR by default.

Despite the fact it does create a 0 bytes tar file and a valid tar file with the .a extension at the end, the restore works correctly.

I did the backup, then delete manually the .android_secure folder from the SD, rebooted the phone in CWM and restored the backup.

Not only the phone reboots fine but the .android_secure directory is restored to the SDCard too, with the application I had previously moved to it.

I guess we could consider it working

I installed Revolution 7.2 on my Mini and can confirm that performance with my Kernel could be better.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
An update on the offline charging bug...

Some days ago I reported that the issue was finally fixed. That by importing in the kernel ramdisk the chargemon binary Mesa Kernel uses and running that one instead of the one in the rom (/system/bin/chargemon) that offline charging was working even from a computer usb port.

Well... I think I've been a little too quick.

Let me explain. I didn't lie and it's true that on my Mini, by using another chargemon binary, now the Kernel does show the charging animation and doesn't reboot in a loop. But it seems to work currently only with a specific rom. When I was tackling this issue I was testing on the Mini which had Zelly Cream 2.5 installed as Rom. When I finally managed to see the charging animation and no reboots I shouted "Yeah, fixed!"

But it seems to be fixed ONLY with this Rom. I tried Pureness V5 (another of my favourites), then tried Revolution 7.2 and both get the phone to reboot in a loop when powered off and attached to a computer for charging.

Conclusion?

As master An0nym0ous was posting in his thread some time ago, something must be connected to the chargemon binary in the rom that makes the fix to work with some roms and not others. What could it be? Still no idea.

I tried exporting all the strings present in the chargemon binary to check for some calls to external applications, trying to replace stuff here and there but still no luck.

There is only something quite clear about it. Unless I can pack all the necessary binaries/drivers in the Kernel and leave untouched the rom, prolly this issue will stay as it is and depending on the rom we use, it'll work or not.

Even if I would find what is the actual binary/library responsible for the issue and we discover it's located somewhere in the rom, the only solution would then be to replace it. That would also mean that most probably the day you'll want to replace my kernel with another, the other one will find binaries it doens't expect and you'll have issues, possibly you'll have to reflash your phone.

My aim is to give you a kernel to use... Till the day you want to use another one and you just flash the other one, without having to reflash your whole phone because I messed with some Rom parts I shouldn't have.

In case anybody feels to have some spare time... I'd be more than happy to hear from you on the matter.

Take care and sorry for the annoyance,

Ka.

Update:

seconds after posting this think I found something. Replacing the charging animation in my Mini Pro with the one of the Mini, offline charging works. What's up with the PNGs and why it makes a difference, still don't know. Checking.

Well let me tell you how I fixed offline charging bug for this GREAT kernel. I copied to my phone "chargemon" and "charger" from Zelly Cream v2.5.2 ROM and the charging animations (I like them very much) and that's it. Now I can offline charge my phone via pc. I'll try later with the original charge animations to see if the fixing of the bug has anything to do with Zelly Cream v2.5.2 charge animations or only with it's chargemon and charger.

Later...

After more tests I noticed that copying back stock charge animations causes again bootloop when offline charging the phone via pc. So not chargemon and charger from Zelly Cream 2.5.2 helps, only it's charge animations. So I copied back from my rom the chargemon file (I deleted charger file - because I didn't have it before, having an unlocked bootloader I don't need it) and copied only the charge animations from Zelly Cream 2.5.2 rom. And now the bootloop it's fixed. I'm not an expert, but I think it's something related to colours. Maybe this kernel has problems showing some colors, that's why he "likes" some of them and others causes bootloop while offline charging from usb cable. Maybe charging from wall socket he gets more power and have the ability to show those problematic colours, that's why we don't get bootloop while charging this way. As I said I'm not an expert, it's just a feeling I have, so 99% I'm wrong:D .

Good day everyone and sorry for my very long post.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
That's pretty much my understanding too and I'm glad to find a confirmation on my speculations in your post.

I quite like the Zelly Cream Rom and use it on my Mini. My Mini Pro runs ICS Pureness V5 which is really good too.

While offline charging worked on the Zelly Cream, it would lead to continuous reboot on the Mini Pro.

Yesterday evening I copied the chargemon animation from Zelly Cream to ICS Pureness and... Bingo! Offline charging worked too on the Mini Pro.

Now, when you inspect the chargemon graphics from Zelly Cream you'll notice that the first image has a red low level battery graphic.

I tried on a low battery level and that red "bar" appeared blue. I don't understand why the colour changed but there is obviously something in the chargemon binary that makes the color to change. So it seems that depending on the binary/graphics combination, in some cases the colours appear right and in some other cases, the most problematic ones, the phone just keeps rebooting.

I'll do some more checks 'cause now I'm really curious to find out what is actually happening.

Take care and thanks a lot for your help,

And the middle charge level (charging_animation_05.png) which is yellow looks blue. But this happens with all kernels I've ever tested (KRsH Kernel, Panic, Radeon, etc). I discovered those charging animations a few months ago (here on xda - on a thread for SE X10). I liked them very much, but the fact that they looked blue pissed me off and made me go back to the stock ones. So, I'm sure it's not your kernel fault that those .pngs look like that.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Ciao,

sorry se il 1.5 non e' all'altezza del 1.4

(sorry if 1.5 is not as good as 1.4)

Let me list for you all the changes that happened between 1.4 and 1.5. Maybe together, if you have the patience, we could try to make it better.

I personally don't have issues with 1.5. No reboots, for example.

One of the main changes that came with 1.5 was the LMK autodetect feature.

You could always try disabling it and see if it makes a difference for you. To disable, open a terminal, su and

echo "0" > /sys/kernel/lowmemorykiller/auto_detect

Full list of changes between 1.4 and 1.5 is:

LMK: Reduce debugging level

[CPU]New cpu voltages for better battery and stability

[PATCH] [COMPILE]Fix another warning

[PATCH] [WIFI]Wireless optimizations

[PATCH] [MM/MISC]Optimizations and make use of rcu_read_lock/unlock MORE

[PATCH] msm7x30: button backlight fix

Added Wheatley CPU Governor

LMK Changes: autodetect oom adj values from 3.4 + sysfs runtime switch

Two boot logos for the price of one

Reducing debugging level can't affect stability, nor make the phone more laggy.

CPU Voltage... Well... That could. Changes were really small though. Would you fancy that 1.6 use the same voltages as 1.4?

Wireless (WIFI) optimizations, worse case scenario will affect Wifi... Not the stability or lag, my guess.

Using rcu_read_lock/unlock... I don't see any issue there either. I'll check if at source it was reverted or not.

The button backlight, definitely not that the issue with lag.

Wheatley? Not the guilty one either. Unless you use it and don't like it. Only got good reports about Wheatley.

The LMK changes, the autodetect... Well, as stated above, for who finds the phone became laggy, maybe try disabling it. If that proves to be the issue, in 1.6 I might put it as disabled by default and people for whom it didn't cause an issue, in the contrary (like me) found it to be an improvement, could enable it via KaMenu.

Logos... That can't be that at all.

Thank you very much for helping me out.

have no so much bugs but:

1. dont know it is kernel bug but when set brightness to half or something like this screen blinks. On highest level dont do this.

2. Wireles I have problem that is connecting to long to network even if network is added to my. But maybe it is because of net tweaks in rom.

3. Logos : I dont like this 2 logos. So make one logo if you can.

4. CPU voltage seems to be ok for me. I dont know about battery life. Deep sleep is ok.

5. No problem with weatley, there are no lags, random reboot of fcs.

So finlly I can say that kernel is as great as 1.4 or even better. So dont know if anyone has lags. I use since a few month the same rom and now from first build the same kernel - yours. And allways all is ok with speed and apps fcs or anything

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] LaShto34:
To pemanently disable LMK autodetect you must create a new init.d script like the one from this .zip. By the way this kernel is the best, but for some roms it is possible that LMK autodetect to not work as expected (maybe because of other tweaks already installed, I don't know). So permanently disable it by copying this script to system/etc/init.d (don't forget to set the correct permissions - for that just check what are the permissions for the rest of the scripts from that folder).
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Originally by lsander

1. dont know it is kernel bug but when set brightness to half or something like this screen blinks. On highest level dont do this.

I must admit that I have absolutely no clue about this but I'll do some research.

2. Wireles I have problem that is connecting to long to network even if network is added to my. But maybe it is because of net tweaks in rom.

In case I understand correctly, that it takes long to join an existing network, this might be due to the setting controlling the interval between wifi network scans. Putting an higher interval makes the phone to wait more between each wifi scan, consuming less battery. On the other hand, it'll take a little more before it actually sees that a known network is finally at reach. We might try to find a better interval than the current defined one.

3. Logos : I dont like this 2 logos. So make one logo if you can.

This is already changed for version 1.6. No more logo of mine, just the plain and stock logo.

4. CPU voltage seems to be ok for me. I dont know about battery life. Deep sleep is ok.

Seems to work for me too...

5. No problem with weatley, there are no lags, random reboot of fcs.

I generally use Intellidemand but Wheatley seems to go well too.

Thanks,
