[Q] how to install GB kernel on froyo CM9 - Defy Q&A, Help & Troubleshooting

hello guys, thanks for all the patience with me haha, but i dont understand it anymore.. im currently running CM9 from epps on my red lens defy with froyo kernel.
Since its a little bit to buggy for me i want to change to a different CM9 but also want the GB kernel.
What to do? just download the CM9 GB build and install it just the same way as i did with CM9 froyo kernel?
I found a thread on this forum that seems really complicated and a little bit to mutch work but i want to do it the right way and not mess up my phone.

With the rom you should flash the attached cm9 kernel

so i just download GB build CM9, put the zip on my sd card, install it and then its done?

U should also download cm9 kernel.zip from the auris's thread in defy general thread, flash it also..

yeaaay it worked, pretty awesome. also it didnt delete anything from my phone which comes in pretty handy when updating the rom. so i dont have to backup everything again. camera is working fine also!

I'm in the same situation. What I want is to install the GB kernel, and yet remain on my CM9, and still be able to flash my original stock froyo SBF if need be, and was wondering if it would just be enough to flash the GB kernel found in Epsylon3's site, and if so, which one (since there are two there)? Secondly, would that GB kernel enable all 4 CPU frequencies?
I'm still on my original stock SBF, which is JORLA_U3_3.4.2_108-2, and has CG31.smg version = 4
Third, would I be able to flash Defy+ ROMs, such as the CM10 roms developed by Quarx, which, as far as I understand, have a custom kernel, and yet still be able to flash back to my original stock froyo SBF?

[Q] [q] cm9/ics/gapps - defy+ 2.3.6 kernal

[Q] hello sir,
Do own Defy+2.3.6 (ryt now using MS2Ginger 3 by walter79 ), want to use CM9/ICS, downloaded zip CM9-NIGHTLY-120112-Defy+.zip & CM9 kernel. kindly suggest proper installation procedure and info abt the ics gapps versions which one to use. i dont want to use other kernal rather than 2.3.6 can i flash CM9 on stock rom
waiting for ur humble replies ☻thanks in advance☻
God bless you All.
Why don't you want to use the Froyo kernel? I wouldn't use this nightly. You can't even phone with it! If you have BL6, flash the BL6-SBF with Froyo-kernel.
Don't use the flashlight until you flashed the CM7-kernel, you could burn it with the Chinese kernel of this SBF.
Then root the phone with the latest SuperOneClick and (after backup) follow my instructions here. Use the latest CM9-zip, ICS-Google-apps and the CM7-kernel(NOT the CM9-kernel) instead of the zips in that post. If you want to have the Motorola-Bootlogo back, also flash the attached Red_M_Logo.zip, or use my CM9-Bootlogo.zip. Flash the CM9-Music.zip if you want to use the new CM9 music app (it's very good, i can recommend it).
If you have BL7, i would wait until eppy makes a build for the Defy+ kernel.
thanks for your replies,
please let me know checking battery version ( bl5,bl6,bl7 ),my defy mfg. date is dec 2011 , details on battery HF5X, b052r984-1001, model L-L-L- DC111109.
and CM9 GB kernel is available so why not to use it, hope u clear my mind.

defy + wont be able to get update of 4.0 do not even try for this
I have a Defy+ with CM9/ICS, it works!
i think i try flashing it on my stock rom... i think eppsy build for gb builds hope no downgrading is required i guess any suggestions and recommendations are welcome.
WHAT VERSION HAVE YOU FLASHED ?
I mean which build are you using with Defy+ ?
i am using stock 2.3.6 and i tried
stock/cm 7.2 nightly.
stock/ics latest builds
works well but no network on second booted rom doesnt get any network ( no EMIE )
hope some one fix this soon or some one did let me know

Did you try using basebandswitcher? Just to search for a frequency similar to your stock baseband? I think you did because default ms2ginger baseband definitely isn't what you seem to be running on stock 2.3.6...
Oh, and btdubs I think Mister Ypsilon is right about using froyo kernel builds for CM9. Your nightly doesn't seem to be too stable.
*EDIT
Oh and veeranna don't forget, BL version (BL5/6/7) is not your battery version. It's the version of the bootloader, and it is very important when it comes to downgradeability.
search it up, I don't do a very good job of explaining bootloader stuff.
Its awesome but lil buggy
I did it! Installed Froyo SBF, rooted, 2nd init, then CM9 for Defy, CM7 kernel, slept at 5A.M :O and bingo there was a pretty stable ICS but without camera! After playing around with it for few hours.. Tested NFS Shift, Angry Birds and everything was smooth as butter except that there was no Camera due to which I restored it back using a full SBF flash and my Nandroid backup
Can be used if you don't need a camera..!
I have a Defy+ flashed with stock 2.3.6 SBF en.asia
http://forum.xda-developers.com/showpost.php?p=20097916&postcount=3
Check this it is working fine. Tested on my moto after a full fresh Defy+ 2.3.6 SBF flash.
There are more stable roms built by quarx and epsylon3 in the defy development thread. Camera works and camcorder works for some users. These devs are geniuses.

[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:
fritolays said:
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.

[Q] [HELP] Downgrading to froyo kernel WIUI

I've really searched everywhere but it's too complicated and i can't seem to find a solution.
So, my issue is that i have installed the ICS CM9 with GB kernel, but i want to install the WIUI 2.4.20 Stable (GB) version that is based on MiuiAndroid 2.3.7 (GB).
I am assuming it requires the Froyo kernel, and if so, i need to somehow downgrade it to froyo before installing it, but i don't know hot to do it...
can anyone please help me?
Also the kernel version of my rom is "2.6.32.9-g21f1a48"
Questions go in the Q&A section

as far as i remember 32 is froyos kernel..(35 is gb's kernel)
so what is the problem???
Numbers are the same I thought. If you flashedthe gingerbread kernel from the recovery, just search for the froyo kernel zip (there is one on epsy's site) and flash it with the froyo based ROM.
Don't forget to wipe.

Hello, I read on a lots of topic that say we have to pass on nandroid and other thing for downgrade.. so i want to be sure that i can downgrade my gb kernel to froyo kernel juste like this..
When i read that, that or that for me it is impossible directly...
Thank you.

[Q] ICS MIUI for Defy+ (GB Kernel)

Ok, I think the title is clear enough but, I'd like to know if there are any MIUI ROMs for the Motorola Defy Plus with a 2.3 (GB) Kernel. Thing is, I have Quarx's CM9 on Multiboot but I'd love to try ICS MIUI on it, but I understand I have to flash Froyo Kernel but don't know what would that do to my CM9 I'm so in love with.
I've searched all the threads on xda and the web but I haven't been able to find what I'm looking for.
Thanks!
Unfortunately Currently there is no miui build that works on gb kernel.
Sent from my MB526 using XDA App
Thanks for the reply! Is there another rom that I should try? I don't really know about another interface for 4.0 but it would surely be great if there were one.
Edit: I have another question, is there a way to install a froyo kernel on multiboot so i can keep cm9 (GB) on my default boot? I already have multiboot but I'm not sure if flashing wiui, for example, will damage the other rom.
Look at the miui ics thread by sesme

Well as far as I know multi boot requires same kernel for the roms. I don't know if any recent development has changed it. You may check multi boot thread.

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

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.
