hi i'm new around here, and think that this is the place for my questions..
about a few weeks started to flash quark's JB defy+ roms on my defy red lens and no problems so far.. but i kinda noticed that cm9 kernel have better battery performance than cm10.. cm10 one have a lot of battery drain.. is that possible or did i do something wrong? i always flashed the battery fix and calibrated again on every flash..
also i would like to know the difference betweens these kernels.. i googled a bit and didn't find anything clear..
sorry if this kind of questions were answered before, post the link of where is it answered if that's the case and i'll see..
thanks in advance! so glad that this forum (and obviously quark's development) is on internet, really helped me..
i'm argentine, there might be some errors on my writing sorry about that!
There is no such thing as "CM9 kernel" or "CM10" kernel. The kernels you can install are the stock Motorola Kernels, either the Froyo-Kernel from the normal Defy or the Gingerbread-Kernel from the Defy+. On a red-lens normal Defy both kernels work, but the Gingerbread-Kernel has a more fine-grained CPU clock stepping.

i kinda got confused when downloaded both.. turns out to be the same one thanks for the correction!
too bad that we are forced to use the stock ones (because of the locked bootloader think, if i read it well), who knows what our defy could do without limitations

Sorry, I'm a fail on searches.
Didn't read all Endless' topic.
Endless7 performs a change in ROM to start the Defy CM7.
Tezet starting ROM compiles the sources, as it should be done.
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.

Thanks for this information bro!!
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? ^^
Just don't want any bootloader error!

Defy kernel Flash
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!
Hi, I'm a noob just bought a new Defy (my first Android device)
I know this will annoy most of you here, but I have been reading this forum for past few days but couldn't come to a conclusion. So thought of posting a new thead.
I have a Defy running on Eclair and wanted to upgrade to 2.3 or to some custom ROMS, but I got too much confused reading all about Stock ROMS, CM7, CM9, MIUI and other Custom ROMS.
I just want to upgrade my phone from 2.1 and I desire a ROM which will give me Great Performance and Good Battery Life.
Can anyone here be kind enough and give me a simple explanation of what should I do.
You can post a wacky caption as well.
Thank for any help.

congrats on your new defy.

any other help pm me or post it.
Thanks, that clears lot things.
Can you suggest me which ROM should i choose? as i said in previous post i want to upgrade. I'm just confused with so many options. Should i go for stock ones or the custom ones? Or which one is most stable. M just looking for speed and battery life.
Thanka for your time.
Sent from my MB525 using XDA
Don't have time to give instructions now, but DO NOT flash a full 2.3.6 sbf/upgrade to 2.3.6! Stay on froyo. It is possible to run all custom roms with this as base, also the newest 2.3.6 gingerbread ROMs. Someone please specify for the guy^^

Okay thanks mate for that info.
Currently i'm on Eclair so i think first of all i have to upgrade to froyo then i can think of going to cm7 and othet custom roms, right?
As you all would have played with lot of custom roms, can anyone suggest me which one should i go with?
Sent from my MB525 using XDA
It's really just a matter of taste. Here are some of the main categories of custom roms:
MIUI
CM7
Modified stock roms
CM9 and CM9 based ICS roms (that's ICS, android 4 . Not stable yet, maybe never 100% without unlocked bootloader )
There are many different flavours to choose from within most of these categories, but there are already a lot of threads about this. You need to read, read, read before you start flashing custom roms. Have you read the All-in-One Defy Beginner's guide? Every defy user should read it. Every single day a noob starts a new thread about a bricked defy: "please help me, my father will kill me if he finds out about my defy", etc, etc. These questions have ben answered 1,000,000 times already, so use the search function before posting!
By the way this thread should be moved to the Q&A section. Moderator will take care of that when it's reported...
Questions go in the Q&A section
I'm by no means a rookie when it comes to android. But this phone confuses the hell out of me. I read the all in one defy guide, and it helped. However, I want to run ics, especially with jb having certain features broken that I use. I don't have the phone yet as its in the mail and I'm compiling everything to root and rom.
So my question is, what sbf rom file should I rsd to run cm9? I also have a new defy+ battery coming, would this battery cause the battery % drop thats heavily discussed here.

I've got an actual DEFY+ (MB526) and I've never had battery drops on any ROM's (tested more than 10 ROM's). I've read a lot about people with MB525's who bought DEFY+ battery and only had problems with it... Don't take my word for it, though and I hope it works out for you fine. Problems, like, it wouldn't charge to 100%. Don't know, Gingerbread kernel and a DEFY+ battd should be enough to make it work...should be
SBF ROM is not the way I would suggest, really... Messing with SBF's is not the smartest call.
What have you got? A DEFY on Froyo? Or Eclair? You should update to Froyo and then root using SuperOneClick and install 2ndInit (the installer is in the Themes&Apps subforum) and go ahead and flash any ROM in the custom recovery.
And may I ask what features does JB have broken compared to ICS? WiFi tethering doesn't work on ICS and does on JB, for a contrary example, though.
Cheers, mate! And welcome to the DEFY lot
That actually clarified a lot. Thanks. Not sure what is on the defy yet. Waiting for its arrival. The way you worded the process made this phone easier to understand as its just like every other moto phone out there.

I guess ill be running on the froyo kernel then with any rom i flash, correct? Also what jb rom would you suggest? It was my understanding that video recording didn't work.

"Which ROM is best" type threads are not allowed on XDA because of the controversy and arguments that question inevitably generates. As it seems like your other questions have already been answered, I'm closing this thread to avoid that type of discussion.
Hello.
First, thanks @Quarx realy thanks, amazing job!!:victory::angel:
so, now the thing....
I'm using cm-10.2-20131030-NIGHTLY-mb526 :laugh: whit the update kernel, but i want a kernel more recently...
i was looking everywhere and i didn't find anything. So when i read this post:
http://forum.xda-developers.com/showpost.php?p=47827999&postcount=1654 form @okij, !!!he extract the kernel from cm 11!!! omg
so i'll try, i took this file: cm-11-20140120-NIGHTLY-mb526 and extract the kernel... make a flashable.zip and Bingo.. new kernel.. more recent..
Now i have cm10.2 with 2.6.32.9 Mon.Jan 20....2014
so if you are intrerested.. you only have to do the same..
My device is Motorola Defy + MB526
Edit: now i put the included on cm-11-20140131-NIGHTLY-mb526.zip
That's all..
Have fun

So, what's the gain? the latest CM11 kernels is more unstable than CM10.2 and the latest 10.2 have no camera for green lens. So what's the point?

Hi
well, now i can tell this, the governors cpu go erratic/crazy with the kernel cm-11-20140131-NIGHTLY-mb526.zip
i look into the dmesg.. and i don't see anything wierd thing... in fact.. i compared 20140131 with the update http://forum.xda-developers.com/showpost.php?p=47827999&postcount=1654 and look similar.. even the same error :silly:
i don't konw what to do..
cpu erratic: i try to change the governor, the most stable one, is boosted. Interactive, smartass and indemand, when i try this, it just jump 300 to 1200 (overclock ), almost don't pass to 600 and 800.
Any ideas how to fix the governors cpu going crazy??
Pd: both dmesg included.
Pd2: new info, i flashed the last one kernel 6-02-2014, and is more stable, the cpu erratic/crazy things... doesn't appaers :fingers-crossed: governor cpu interactive
Thank's
Have fun
