I´m currently using CM10 by Tezet, and I have flashed the GB kernel that Tezet put in his post. It all works nice and well, but I wanted to try Danik's MS2Ginger. Does anybody know if it works well without flashing the custom kernel from Danik? Can I just keep my current kernel? If possible, I'd appreciate the opinion of someone who has tried this.
Thanks in advance!
PS: On a side note, my current kernel (CM10) is named: 2.6.32.9- Jellybean, etc, etc. I had the impression that the Linux Kernel for Gingerbread (that is to say, the GB Kernel) was 2.6.35. Why keep the froyo kernel number?

I think you can keep your kernel but you would really benefit from the new one when using Danik's ROM. I haven't tried his ROM though.
CM10 has a thing called "2nd-boot" which allows us to boot custom kernels, from an already running kernel.
2.6.32.9 is the Linux kernel version (which btw, the number doesn't have anyhing to do with the Android version, but newer Android versions work better with newer kernels, that's why there is a WIP 3.0.8 kernel for the Defy). "Jellybean" is just the branch of code. That kernel has the ramdisk and init binaries (I think, kernel experts please correct me) necessary to boot JB.
Motorola has never actually released a kernel newer than that for the MS2, the "official GB kernel" it's an older kernel "built" for GB.
Hope it helps.
Thanks for answering!

Hi all
I see genokolar's latest cm7 rom for u8800 can't be used with franco's kernel. I use this combo now, on the v11118 rom. No doubt this'll get sorted soon, but...
If I want to update to 111128 now, or if this incompatible issue happens again, what can I do?
Does the geno cm7 rom include a "default" kernel?
If not, what other kernel options are there? Seems to be very few in the u8800 dev forums, and nothing seems to be actively maintained (note, not u8800pro!). Should I return to the stock kernel? And if so, how?
Thanks to all for the great work going on here, my u8800 would have been swapped for something else if it hadn't been for the awesome dev work being done.
every rom has its kernel...
thanks mate
The lasest CM7 and CM9 based on froyo kerenel or gb kernel which are using the same boot.img kernel from foryo or gb.
I wonder why does these build use the boot.img by adviced?
May some system files are from this kernel boot.img ?
Is there any relationships?
or just you adviced to use this kernel by no reason just with feeling good?
or could we use the other boot.img from the other froyo one or gb one?
Thanks!
You can have a try .hoho

firstly, there are many differences between froyo kernel and gingerbread one. such as the camera driver(green lens and red lens), the 3d driver and sth else. that's the reason it is hard to build a rom which can boot based on either two kernels.
secondly, there are differences among froyo(gb) kernels. e.g. remember there's one time we cannot boot into bootmenu with the asia froyo kernel? it shows there must be some differences among froyo kernels, although not as many as differences between froyo and gb kernel.
i think things above explain why there's always a recommend kernel. devs are working on the rom based on a specific kernel, and have no time to test it compatibility with other resembling kernels, although sometimes there's no compatibility problem.
I am currently trying to get full battery of my defy+ to work under MIUI. Being CM based i assumed it would work with the CM battery patch. It doesn't however. I know which files need to be replaced, would it be a good idea to just grab the files from the CM9 defy+ build and replace them?
For those that are interested doesn't work = battery only showing full with question mark icon.
Having same problem and seems there is total silence in all forums concerning this issue. If you manage to solve it please let me know !
Hey, guys I'm using MIUI Pikachu Edition by einsteinno1 and it has full DEFY+ support (battery charges up to 100%)
It's overall an awesome ROM, after trying CM7.2, latest WIUI and MS2G v3, Pikachu is the best one for me.
My DEFY+ was on 2.3.5, so I flashed it down to Froyo before flashing Pikachu
Cheers!
I have the same Defy 2.3.5 but I don't know how to install a diffrent ROM/interface ...

Search this wonderful Forum - There are many threads telling you how to install a new ROM / interface
Well then I will definitely give Miui Pikachu edition a try As far as I understand Froyo version is the best to use to flash Miui right ?
Hi all,
About the Defy+ battery. This battery is only support by GB kernel. So nevermind the patch you applied, you'll always have a bad result. This patch works on CM 7.2 Defy + because this rom doesn't incluse the kernel and use the GB one of your phone.
So the only solution is what nisky+ said... Flash before the 2.3.6 SBF on the dev forum who allow you to flash a Froyo kernel first...

Froyo is the safest way, yes, and it will work without problems. It should work when flashed over 2.3.4, too, but I haven't tried that, myself.
@mdt24 Then how come I don't have battery problems now when Froyo's kernel is used
P.S. It's niksy, not nisky
Hi niksy ;-)
It's because I think this rom doesn't incluse kernel, so you always run a 2.3.4 GB Kernel...
quote from Miui Pikachu edition : IMPORANT!!! this Rom works only on Defy or Defy+ with Froyo Kernel or Gingerbread 2.3.4/5 Kernel. All with 2.3.6 Kernel have to downgrade to Froyo Kernel, because the new Motorola Kernel won't work with MIUI. Just use this Tutorial on XDA Developers
But I could be wrong in my deduction, so Please, can you give us the number of the kernel you have with this pikachu rom ?...
What I did before was downgrade from 2.3.6 using the sbf the dev provided that allows you to downgrade to froyo then I flashed Miui official rom and still had problems with battery. Kernel version currently is : 2.6.32.9gb08c3c8 if that makes any sense to you cause I personally just don't know anything bout kernels... I just downloaded pikachu Miui and will give a try soon and share the results with you
Hey all, thanks for the replies. I already know about the limitations of the patch and which versions the driver works with. That is why i flashed the 2.3.4 kernel before using MIUI and therefore the defy + patch. I just don't get why it doesn't work, do i need to use a defy+ kernel?
I will grab the files used in the working MIUI Defy+ rom and package them as a flashable .zip for other users.

Mate, you are right about the ROM, it doesn't include any kernel, but I said that I flashed that special version 6 Froyo (that's a full sbf) before flashing Pikachu!

The kernel you mentionned is a froyo kernel...
As you all I try to understand why it's possible that the defy+'s battery works or not with the patch. It's sure it works with a 2.3.6 GB kernel and a patch for the system (battd, lib) used by the rom if the new rom doesn't include a kernel.
It seems that if the rom include a froyo kernel the patch doesn't work...
So... may be a way to understand

Yes but I'm pretty sure than this special version has a GB kernel. It's just the bootloader who accept all kind of kernel...
Check your Kernel number, I think you must have something like this 2.6.32.9-gbdd614e...
Ok after some testing I can tell you that the battery charged to 100% only the first time I booted.Since then it has only charged till 90%. I also did calibrate the battery the first time I flashed the Rom but no results

It's 2.6.32.9-gb08c3c8 - the one you said it's Froyo Just checked!
And for the battery... First time it charged to 100%, this time it stuck at 90%. Quite weird... But, that is with Froyo kernel, as we've come to conclude.
But, on the other hand, my bro's got a DEFY+, too, with CM7.2 on it and with Gingerbread kernel (27th January DEFY+ nightly) and the battery goes to 100% every time. I will test Pikachu on a Gingerbread kernel, cause I can't really live with this bug :-/ Will let you know how it went, now I'm off to find a 2.3.4 sbf!
I had the same idea and have already downloaded a full 2.3.4 GB sbf to check just that !
i wish a 2.3.4 GB kernel can fix that, although I think the only kernel able to fix this is 2.3.5 and above
Hi.. I m new to android... I just want to ask how can I add music contol to notification toogle bar like that in cm mod..... I m using pikachu edition on my defy plus and its really great ... I haven't faced any problem till now.. thank u dev for such a beautiful rom...
hey buddy....i was runing on 2.3.5 than i tried a rom called [Retail British] here ; http://sbf.droid-developers.org/umts_jordanplus/list.php

i upgreade it by automatic update so it became 2.3.6
then i again flash it through [Retail British] after that my device not able to power on just with white led light but i'm able to flash the device ..so can u suggest me a suitable rom for my device [Motorola defy+] ??

Thanks for ur Info.. tried to install Pikachu edition on my Defy+ 2.3.6 nd failed. But now using CM10..
hi guys, I would like to ask experienced users what is the difference between the kernels we used on our Defy(s)
Froyo Kernel vs Gingerbread kernel vs Walter79's Kernel
I first encountered this kernel upon viewing the CM9 update thread
I have a red lense defy and the very first rom I flashed was the official CM7.1 so I am aware I do have a Froyo Kernel running on this bad boy.
what is the difference/ advantages?
which is better?
is it safe to flash one over the other?
is it easy to flash? like how we flash roms? we can always go back to to Froyo kernel from the gingerbread or walter kernel and vice versa?
I think a lot of noobs would appreciate your answers.
I will edit this post and add your answers so that others may find it useful as well

Ans:My experience says that the main advantage of using GB kernel is battery life..
Defy-4.5.3-109_DPP-11-kernel is well known for awesome battery life.
which is better?
Ans: I personally think Walter79's kernel is better in every sense.Unfortunately for old defy owners(SOC camera green lens), camera wont work on new kernels without any extra fix..
is it safe to flash one over the other?
Ans: Yea its 100% safe..i personally never had any problem as such..but i heard few people faced bootloop..in any case you can always go back to froyo or watever kernel u were using
is it easy to flash? like how we flash roms? we can always go back to to Froyo kernel from the gingerbread or walter kernel and vice versa?
Ans: As i have already mentioned above, we can always switch between these kernels..just remember not to flash any GB kernel based sbf or else u will be stuck! before flashing any unknown or less known kernel PLEASE USE THE SEARCH option and know more about the kernel and related problems.
All the best

Please also share Camera fix (link) for GB kernel for SOC Camera and also mentioned whether downgrade is possible. Your help will be appreciated.
anyone correct me but we can do dual boot but can't install dual kernels?
say
cm7 (froyo kernel ) as system
cm9 (gingerbread kernel) on SD
and will Gingerbread kernel work with cm7 for the defy, red lense?

No, can't do it. Both ROM's should share the same kernel.
thanks Auris, would you be able to add anything or negate anything that was previously posted about the Defy Kernels?
Please help me a bit with those kernels! I have a defy+ with 2.3.6 base and one of those newest official build nandroids. Can I flash Walter's kernel? ^^

i have a motorola defy green lens currently running cm9 4.0.4 (camera's not working but i don't care much for the camera ) . ok here's my problem i'm trying to flash a different kernel on my defy.. the current kernel im running is 2.6.32.9 cdt 2011 but i need better performance and i tried to flash semaphore kernel. the flash was successful but i see no changes and also in the settings>about phone the kernel version hasnt changed. i need help so that i can flash new kernel properly.. thanks
Hi!
I realize this is a very old thread, but it seems to be one of the few addressing the (dis)advantages of the froyo vs the GB kernel (independently of the ROM!).
The 720p-recording is really not important to me, but battery life is and I just read here that it would be better on GB kernel.
Do any of you have further experience with regards to battery-life difference between Froyo and GB kernels (not ROMs)!? Is it a big difference (to what extent or through which features?)
I have a MB525 with red lens and Froyo kernel, so I could go for a GB-kernel.
I've recently rooted my smartphone and flashed WIUI (3.1.27, GB&MIUI-based) on it, because (1) my phone was slowing down, (2) I wanted not to have any bloatware anymore and (3) I wanted some apps that only run on Gingerbread/2.3+ (e.g. the offline-language-package-feature from Google Translate). Almost everything is now better.
BUT, my battery life got worse! I've now down-volted my smartphone to a stable point and set it to 'smartassv2', but am looking for further improvement for the battery life. As WIUI can be installed both on froyo and GB-kernel, I might also update the Kernel...but only want to take the plunge if it really would make a difference...
any advice or experience is welcome!
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...
