[Q] About Kernels and CM9

First of all, I'd like to thank all you guys for all great work here on XDA, thank you very much!!
I have a Motorola Defy (MB525) with Red Lens and although I've changed the ROM of my Defy many times, I'm still new and I have some questions:
The first ROM I've installed on my Defy, was CM7 (unofficial, ported from Quarx), then changed to MIUI, then came back to CM7 (official) and now, I'm using CM9 (24/Feb) from Epsylon3/Quarx (from this thread http://forum.xda-developers.com/showthread.php?t=1432100 ) and this build is for Froyo Kernel, and, in this same thread, I've read that GB Kernel is better for CM9 and my Red Lens Defy...
My question is: can I flash CM9 for GB (with GB Kernel) and later return to CM9 for Froyo (and Froyo Kernel), or MIUI, or CM7 if I wanted to??
If I flash CM9 for GB (with GB Kernel), can I go back to stock if I need to??
Well, sorry for this noob questions and sorry for my bad english

well, my personal opinion is, that GB is always better for defy with red lens... only reason for froyo is the missing green lense support in gb, i think ...
i also think, that the kernel for these cm9 roms are flashed with an fixed sbf ... so it doesn't matter, what you have as stock system ...
that is no pro-answer, just a few thinks, i've read and hopefully understood ...
the whole romchange of defy is not easy to understand cause of that locked bootloader things and so on ... i also got a crazy problem with my defy+ as you can read in my thread ...
hopefully, we will get the answers we need to get our systems running as good as we like ...

Does that mean that those of with green lenses won't be able to upgrade to gb kernel if we want our cameras to work? (i mean by the time there's a cm9 stable)

i flashed cm9 feb. 29 release in my green lens defy.. and have camera preview with autofocus on it.. btw i flashed the cm7 kernel.. and i think cm7 kernel is froyo kernel.. cm9 kernel is gingerbread kernel.. anyone can elp me? how to move apps from phone to sd card?

I've found this:

I packed the two different kernels into clockwork flashable packages.
1. Flash either a nightly or restore a nandroid.
2. Flash either CM7_Kernel-signed.zip or CM9_Kernel-signed.zip; depending on what you've installed.
3. Reboot.
CM7_Kernel-signed.zip
CM9_Kernel-signed.zip

that means that I can go to CM9 (with GB Kernel) and then, if I want/need to, go back to CM9 (with Froyo Kernel) or any ROM based on Froyo Kernel, right??

You're right. I did this and works. Just flash the kernel based on the corresponding ROM and you're good to go.

Should I install CM9 kernel?

I have a Defy, installed the 4.5.1 DHT25 rooted SBF.
Then I install CM9 using the instructions stated in this thread: http://forum.xda-developers.com/showthread.php?t=1618904
When I reboot, it goes to flash rom screen, showing error:
Err: A5,70,00,00,3D
Should I install the CM9 kernel as stated?
or as I'm using the 2.3.6 Defy+ SBF, I don't need to install CM9 kernel?

Ya u should install
I think cm9 won't work with 4.5xx kernels

You are using a 2.3.6 DEFY+ SBF? It's bl6 or bl7, either way you can not flash those kernel zips, they are meant for lower bl versions. Make sure you are flashing a Gingerbread (or jordanplus or DEFY+, it's named in many ways) ROM and skip the kernel flashing step.

What the hell? See this - link. Can you see 4.5.x in the middle of the name of every of those stock sbf files? Any ROM built for Gingerbread will work with any of those kernels.

Hi,
That partially answered my query. I would welcome if you could answer my query in some detail.
On my defy with green lens I first ported original stock Froyo then installed GGL ROM. After that I installed CM9-NIGHTLY-120617-Defy.zip but did not install any kernel.zip as suggested by other forums. And then installed gapps-ics-4.0.3-20111217 and most of the things including Opera Mobile, Camera except panorama/FC on stop thereof and GPS and few apps that I use. Opera Mini is not working where I live even via 3G.
Now my question was whether any GB kernel marked for Defy (or even Defy+) work for such CM9-ICS update.
My current kernel via GGL is [email protected] #1 Wed Apr 6 15:55:29 CST 2011.
Is there any other better kernel than the above that you my suggest?
Thanks.

If you flash a Gingerbread kernel (also named CM9 kernel) your camera won't work. Green lens doesn't have compatible drivers on Gingerbread.
Why would you want Opera Mini when you have Opera Mobile working?
If you want a fully functional ROM, I suggest you switch to some of the CM7.2 builds or MIUI Pikachu Edition or WIUI GB. These are all great, stable, fast and pretty much bug-free.
As for the kernels, changing them doesn't help much in my experience, but I do know that Epsylon somehow added some libraries (thought they are onlu meant to fix wifi tethering on CM9 as far as I know) in the Froyo kernel available on his site. You could try it - http://defy.wdscript.fr/kernel/ . (This one: kernel-froyo-222-179-4-signed.zip)
I see that you used the oldest gapps possible, I'm not sure why. Get the latest zip from here (ics version is for CM9, yes) - http://goo.im/gapps/
So, what I suggest to you if you want to stick with CM9:
1 - get the latest gapps, get that kernel and you already have the latest CM9
2 - full wipe (data/cache/dalvik)
3 - install zip - kernel
4 - install zip - ROM
5 - install zip - latest gapps
6 - wipe cache and dalvik (not necessary)
7 - reboot and see how it goes
Panorama still won't work after that, that's for sure, but I don't know what other problems you've experienced....

But why doesnt it work with 4.5.x kernels?
Mine s defy ...I'm using cm9 ( defy + gb kernel build) so cm9 doesnt bootup wid those kernels...why?

I really can't figure out what you are saying. Which CM9 build are you talking about exactly? Which kernel(s?) are you talking about exacly? Would be good if you could give me the links to both, so we can resolve the confusion

its work on DEFY
im on CM9-NIGHTLY-120609-Defy+.zip and 4.5.2_DHT-22_kernel work great
but u MUST flash cm9 kernel ...reboot and 4.5.2_DHT-22_kernel...
i dont know why it happened but i forgot to do it many times and my defy cant get even to recovery
i need to flash full SBF to fix this...i hate when its happened....(i will really glad if there are other way)
i really hope for that u done backup for your apps
p.s.
u must flash DEFY+ version for GB kernel
and DEFY for Froyo kernel

Thank you niksy on your info on kernels. However CM9 works well on defy with green lens except for the panorama mode.
I found the old gapps smaller in size. However after your post I reinstalled a later one.
I prefer Opera mini as it has a smaller mem footprint. Since mini is not working here I use Boat browser mini which is quite comparable to Opera mini in speed,
However I have one issue on CM9 when I copied SIM contacts. My phone book got bloated to over 3 times the size with some of the entries duplicated from 2 to 5 times!
With MIUI/WIUI/WP7 I feel the originality of Android is lost with those boxed icons.
Besides I read in one of the posts in xda that WIUI ICS is based on CM9.

Defy+ from MIUI to CM10 Jelly Bean (Quarx's Build)

Hi guys,
i know that there might already be an existing thread about this but i wouldn't create one if i had found something that helps me.
Im using a Defy+ with Miui 2.3.2 and i really want to move to CM10 Jelly Bean.
I've found a really cool thread from Quarx and Epsylon about installing CM10 on a Defy+.
I already downloaded the newest release (04.09.) zip file and also the google apps and put both on my SD card.
But as it seems and as i have heard, it's not possible to move from a NON-CM version like MIUI to a CM version by going the typical steps (booting phone in recovery mode, choosing the Quarx zip file and installing it).... or am i wrong?
Can i just put firmware and google apps on my SD card and install that zip from recovery mode and everything's working well?
I didn't mention to wipe the dalvik cache here cause it's just a detail. I just wanna know if this MIUI to CM transformation is possible.
Hope you can help me, i really wanna use Quarx's CM10 cause i've heard it's amazing.
Thank you guys

is there noone who can help me with this or at least give me a link to another thread that already deals about this?

I don't think there would be any problem provided you wipe data/cache/dalvik before flashing CM.

ahhh, now i remember which problem there was with changing from MIUI to CM.
Doesnt MIUI use another kernel than Quarx's newest CM?

Unless and utill you downgraded your kernel to the froyo one, you won't have any issues. I have flashed WIUI GB version for Defy+ and for me the kernel is still the stock one.

Can anyone hep me with this? I had miui then tried to flash cm10, i followed all the steps but when booting up for first time it got stuck miui screen. I guess this means i have the wrong kernel but im not sure how to correct it

1. Flash a new kernel OR
2. Flash your stock SBF, re-root and go from there OR
3 (New option now) Flash the latest quarx JB CM10 with custom kernel included.

Answer : How to custom Kernel ´Defy+ JB Quarx

Everything for testing!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I wrote this for maybe less confusion
Works with my Defy - red lense Bayer cam - on Defy+(gingerbread Kernel) Jelly Bean Quarx 24.8 Rom
I´ve
1. Flash test_2ndboot_6.10.zip from http://quarx2k.ru/ or my 2ndboot_06.10.zp from attached dropbox (search for 2ndInit recovery if you dont have and root your defy)
2. Boot into Recovery
3. Set 2ndboot as default
4. Go to tools/adb daemon and klick it and then reboot
If you want to go back to stock gb kernel flash stock kernel -like gb-234-451-134-signed.zip from dopbox i´ve attached
Remember everything is for Test the custom kernel
OT - Multiboot is ok with CM7 but akku is always 100%
https://www.dropbox.com/sh/4fg71wuehyibzzx/oanepGgaRR
BIGNOTE: Green lens users who flashed redlens builds please dont try using flash, you will end up burning it like me and many others
Big thanks to our great DEV´s Quarx as porter :good: , Walter for fixing :good: and MS2 Dev czechop who made this possibile :good:
Great works men !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11

Defy red lens with defy + build gb kernel
Sent from my MB526 using xda premium

I have done it in such manner
1. Prepared on SD card:
- CM10 ROM 24/09 for MB526,
- gapps for JB
- Qkernel 2ndboot_06.10.zip (with improved 2ndboot.ko)
2. Done factory reset and viped caches
3. Installed CM10 and gapps in normal manner
4. Flashed Qkernel
5. Went to bootmenu and choosed 2nd-boot (there was no chance to set it as default... i think, because phone immediately reboots)
And achieved "half success". All is working but with extremely lags... Was said so after first bootup system suppose to be laggy and needs to wait some time on sleep state with WiFi switched off. I was waiting whole night.
So now I want to know, if my procedure is right.
Nobody mentions gapps during instali of ROM - i suppose it's so trivial so nobody count it on...
Another problem - is there need of factory reset or cache wipe?
After installing Qkernel i went to boot menu to set 2nd-boot as default, but when i choose 2nd-boot phone reboots and I don't know what now with this setting up deafult 2nd-boot...
I am trying to fond any reason of system lagginess. Maybe something was done wrong. What's your opinion? To change ROM build? Or something else...

Of course I can try, but does it make any difference? Well, will see...
So I'm supposed to flash your kernel "as is" without much deliberation over existing installation?

If you are on boot loader ver 7 i cant say that it would work

Wrote about problems with custom kernel . Look around page 67 if your defy+ was stock bl7

I am using regular Defy with Bayer module and as first owner I am sure so there was not flashed any full sbf except once when I was forced to flash stock Froyo, so there is no case of BL7 I think...
So if I try can I flash this kernel over existing system or should I reflash ROM too?

Tried without success. Ill have to flash sbf rigth? Which do you recommend?

what are the advantages of using this kernel?

I don't know the advantage, for me it works as i do.
I started with stock cee European gingerbread which I've flashed after offical update comes out
New nightley from quarx cm10-2ndboot-nightly-defy(+)
Is out & works a bit faster

In General section http://forum.xda-developers.com/showthread.php?t=1909242&page=84
they talk about BL5 and BL6 is supportet by quarx not BL4 and BL 7
Some say it works on BL7
But better read there for your self.......beforr you flash anything and think about warrity/garantie

For every booting i had to umount and mount again the battery.
And no Deep-Sleep in about 12 hours
Anyone else with this problems?
---------- Post added at 09:37 AM ---------- Previous post was at 08:49 AM ----------
Now Deep-Sleep is ok. Dont know why .... But ... Quarx said in the xda-developer thread,
that with no usb-cable and with wifi disabled the defy should go 10-15 sec. in deep-sleep.
Before i have had usb-cable on or wifi enabled. Maybe that has been the reason.
After 3 hours 14 % battery drain ... not good ...

Quarx edited a new Rom today.
But after getting more and more slow reactions from the defy+ i flashed the 24.09 version.
All tips didn't really work in a good way.
And I need my defy+ functionabel this days.
But next time again ...

And today again a new kernel for update as *.zip ...
quarx2k.ru/cm10-2ndboot-nightly-defy(+)/update_for_11.10_v2.zip
13.10 Kernel update:fix wifi tether(reboot), reduce battery drain, compiled with linaro 4.5, fix charge only mode, cleanup unused drivers.

[Q] RED led blinks which is the CM10 Nightlys latest build for MB525 Green lens?

RED led blinks and it is in a bootloop when i upgrade my defy with CM10-20121128-NIGHTLY-mb526.zip ? can anyone give me the link for the CM10 Nightlys latest build for MB525 Green lens and the correct jellyx kernel for MB525 Green lens?

The one you are flashing is an old nightly.
You can find the latest CM10 here- http://quarx2k.ru/cm10-2ndboot-nightly-defy(+)/ or here-
