I've been reading, and re-reading, and re-re-reading, and now that I finally have my nexus one working with wifi-calling again (for international use), I'm willing to give up the wifi calling on the defy and go into a non-stock TMobile ROM. Since I did like the ICS roms on the nexus one, I think I'm going to go with one of the new CM9 ones.
Based on what I read, I think I understand a few things, but also have questions:
1) Kernel - It's the software underneath the ROM. Think device drivers. I would assume that since I'm on the latest TMobile ROM for the Defy, I'm on Froyo. I have a red lens (tested with logcat), so the question is: Is there any benefits to upgrading to the GB kernels? If I don't like the ICS/CM9 kernels, will it allow me to run CM7.2 kernels and be happy?
2) Quarx vs Epsylon ROMs. I see all these bug threads, and separate threads. Etc. Etc. What's the difference between them? And will the question from the kernel allow me to enjoy differences between the two builds? There's just way too few/many threads on these ROMs, and I'm confused with which one has which bugs and which one stands where. There seems to be 2 builds for each person's ROMs, but when you go into their download sections, it's also different dates with different "fixes", with different mirrors carrying different versions. And when I'm trying to figure out which one has bugs that I can live with, the bugs are in one consolidated thread, for every combination of kernel/ROM.
So the question is - Where can I get info on the latest pros/cons of each ROM and which kernel is needed to support it?
Anyways, point is, I'm lost. I'm hoping to push off the purchase of a galaxy nexus. I like the Defy. I like how I can treat it like junk but still work. I wish I can do inductive charging on it, but it is what it is.
Help???
Basically both devs each made 2 seperate builds one for red lense defy and one for green lense. They use different camera modules so they need different support. Seeing as you have red lense you should go with those (defy+ roms).
The defy cm9/gb kernel was taken from the defy+ and is needed for the defy+/red lense roms to work. To try the defy/green lense roms you need the cm7/froyo kernel which is from the regular defy.
Cm7 uses the froyo kernel and you can just reflash the froyo kernel if you want to go back to it.
About quarx and epsylon I think quarx supports the red lense better.
If you use quarxs defy+ roms on a reqular defy then you need to flash a battery fix.

epsylon and quarx has different camera modules so that they can split the work. merging of this build will most probably be done when stable release of cm9 is released. Quarx has a better working camcoder but his last build for green lens was long back. If u have green lense go for epsylon froyo kernel.

Hello everyone. I have some questions about the different Kernels and ROMs running around. All the information is completely scattered throughout the forums, and it became almost impossible to get proper info.
I like to be sure about what I'm doing, and currently, I haven't been able to do much.
FYI, I have searched a lot on the forums, and everytime I find a pertinent info, the discussion mixes up discussions about different roms and kernels, or just assumes I know stuff I do not.
My first question is: How can I get know what is the CG version of a Kernel? Right now I'm running CM 7.2, under Froyo Kernel (used the stock one), and I want to be able to reverse everything I do.
Second question: I know there are lots of different CM versions out there, from Quarx, Epsylon, etc... what are their repositories, and what kernels do they use?
Thank you in advance.

All the custom rom: CM7, MS2ginger,MIUI... Use froyo kernel
If you want flash GB SBF, use only Nandroid and fixed SBF... Never flash full GB SBF
I have read it, that's what taught me about CG versions, However many ROMs requests a specific kernel, such as CM7 Kernel, Defy+ Kernel, and so on... not sure if I understood if right, but isn't changing the kernel what can change the CG version?
So because of that, I have not messed with anything that requires a different kernel, I have no idea on how to be sure of the CG version of anything
More infos there :
http://forum.xda-developers.com/showthread.php?t=966537
All CM7 have CG = 4, CM7/CM9 Defy+ are only for Defy+ user and don't have kernel inside and use the original GB kernel CG = 5 or 6...
Thank you! The first few lines of the link already showed me how to find the CG version, exactly what I wanted!
if i knew, i wouldnt flash a full GB SBF.
now that i did it, what can i do?

currently not much I believe. eppsylon3 also got stuck - not able to downgrade again.
perhaps we just have to wait until our devs break the damn bootloader
so we are stuck in this, right?
please devs, HELP US
btw, it stays in motorola logo, a blue led shows, then a green led, then it disappears.
what can I do to make it work again?
I have one question.
Why use the froyo kernel at all?
Upgrading ALL defy/defy+s to the latest (rootable, 1321 or 139 preferred for simpler root) 2.3.6 GB kernel would simplify rom/kernel development for the devs. Since more and more defy+s are in use they can simply drop development for the froyo kernels and focus on the GB kernel, since now all defys, whether the old one or + would be running 2.3.6. Any current devs (if they want to retain current status) would just have to switch to GB kernel support for their rom once and keep it that way.
Because the SOC module (green lens) is compatible only with the Froyo kernel.
Upgrading to the Gingerbread kernel means that the camera will be unusable for those Defys.
Forgot to add: Having a locked bootloader sucks.
Trimis de pe Defy CM9
So all defys are not equally upgradable to GB (kernel)?
What kinda BS policies are these from Moto? Locked BL they have their reasoning about not wanting users to hard-brick the phones, but what reason to not allow officially updating to GB for ALL defys?
Unfortunately, no, not all Defys can be upgraded to the Gingerbread kernel and still be fully functional (exception being the Greenbread mod). And the devs can't do anything about it because of the locked bootloader.
Regarding Motorola and it's policies - it's all about the money. Outdated phone -> unhappy people -> they buy a new, updated phone -> happy Motorola.
Trimis de pe Defy CM9
Using Froyo makes sense for those, who want to keep the warranty and have to stick to the highest officialy available version. I had to update because CM roms work only with Froyo upwards.

They buy a new, updated phone from someone else. By keeping the Defy stuck on Froyo they've made a lot of people decide never to buy any product from Motorola again.
that is true. the bl lock stops us from changing kernel.

This means that there is Froyo source, but not the driver source for the green lens ?
At this moment, if I want to improve my Defy (green lens, original Froyo 2.2.2), what firmware is the best?
It should support everything (3G, 2G, HSDPA, WI-FI, camera for both photos and video recordings, GPS, sensors and so on).
I'm a newbie and for me it's a bit confusing to see a mod called, e.g., "[ICS] CM9 Android 4.0.4 for the Defy (Froyo kernel)" (there are others, this is only the first I've found... )
ICS is ICS, Froyo is Froyo.
What I gain and what I loose with an ICS "Froyo Kernel"?
Is it ICS or Froyo painted with ICS dust ?

Well, I've just upgraded to WIUI 2.4.20 (GB) and now I've GingerBread (2.3.7) full working.
My Defy has a green lens and the camera is working, both for photos and videos.
Have I missed something about the thread?
Are you sure WIUI changed your kernel? ROMs and kernels can play mix'n'match.
Motorola has locked the bootloaders of defy
Thus we can only use motorola signed kernels.
Defy has a froyo kernel and defy plus has GB kernel. Both signed by motorola.
Only these to can be used in custom roms. Even in ics and even in jelly bean (Android 5.0) we will have to use these kernels as long as motorola doesnt unlock the bootloader. Froyo build of ics means ics that runs with froyo kernel. GB kernel works only with red lense cameras of defy and all defy+. So only froyo build will work for green lens defy.
^^
This was exactly why i was confused. Do you mean the green lens Defy cannot be officially upgraded (either OTA or RSDLITE) to GB ? And the red lens Defy can be upgraded to GB?

Maybe you're right...
Android Version 2.3.7
Kernel Version 2.6.32.9-gb08c3c8
But the 2.3.7 version is GingerBread, whilst the 2.6.32 kernel version is Froyo.
So what's the point ?
The mods are always Froyo but with GB features ?
Defy with green lens can be upgraded to gb kernel but many features inculding cam may not work.
The gb kernel was extracted from defy+. As defy+ has only red lens the gb kernels works with defy red lens also.
Fully functional green lens gb kernel will be possible only when defy gets an official gb update (highly unlikely) or when the defy bootloader is unlocked(higly unlikely too).
---------- Post added at 04:05 PM ---------- Previous post was at 03:58 PM ----------
defy green lens with gb kernel may end up in a bootloop.
so thread with caution.
Flashing an GB sbf will prevent you from coming back to Froyo(Downgrading).
Always try to flash using CWM to keep downgrading options alive
Are there no "fixed" GB SBFs to keep downgrade options alive?
No defy owner should upgrade to gingerbread kernel by flashing an sbf. Our bootloader can load the gingerbread kernel, the gingerbread bootloader can't load the froyo kernel.
So when you flash the sbf you can ONLY use gingerbread kernel based ROMs from then. Otherwise you can just flash the kernel you want from the recovery.
It would even be wise for defy+ owner with bl5 and 6 to flash the bl6 froyo ROM so that they can use both builds by just flashing the right kernel.
About official gingerbread: they are for the defy+. Officially the defy has no gingerbread ROM. For some countries the defy even stays on eclair. Although it would have cost Motorola 5 min to replace the camera and battery drivers. Only problem is money for Motorola and the operators.

Hi guys i'm very confused about Cm 9 nightly builds.
Is Eppy's 13/05 Buils is the stable vesion?
As far as I know there is no stable versions for the defy!
CM make stable versions but not for the defy well not the defy+ anyway and epsylon mods the CM version to work on defy with other mods as well. Like tweaks and he may add things and remove things.
So no its not stable. I dont think there is a stable CM9 build, the latest Stable CM build is CM7.1 AFAIK and it may be used by epsylon or quartx or other moders but I dont call that stable.
here is CM lastest stable version for the defy (not sure if it works on defy+ as its just a jordan version and there are no jordan+ versions)
http://download.cyanogenmod.com/?type=stable&device=jordan
Edit: so you know a stable version is considered one that would run like a stock version and one you can trust to put on other peoples device that would not know how to mod it. All the rest come with risks and they could work perfectly fine for you and not so well for others. From what I have found defy can be a real pain to work with and there is no real time support (by real time I mean we have to have modders like epsylon and quartx to mod the ROM's that are made but say CM to work on our devices) and the defy having so many makes and variations then there is alot of conflict and what works on one device may not work on the same one for another person.
Its a real pain and the bootlocked on the moto phones are a real downfall. I found out today that telstra got the defy as it meet there spec for rural service and MOTO changed them specs before shipping it out then telstra got them to change it back to the original. So the same device has so many different changes its not funny. As well as the cameras and batteries and all that so who knows what else has been changed!
Nightly's are not stable..
just try a nightly..if everything wat u need works fine then stick to it..so give it a try for atleast 1 week..
If you meant the latest version then it's Quarx' Version from May 11. Currently I am running this one on my Defy+ and for me it runs pretty reliable, but it's still not called "stable". More like "alpha" or "beta".
Hello, I have a motorola Defy with 2.2 OS, I've been looking on the web some threads where it says that you can install the official 2.3.5 release for Defy+ on your regular Defy, does this work? is there any disadvantage? I'd like to update using an official update, not a modified one, thanks in advanced!
Questions go in the Q&A section
You should look at what kind of lender you have in your device: green lens means that you have to use defy Roms, red lens means that you should use defy + roms.
More on this asking to Google or xda search bar ;-)

There are several disadvantages of flashing a Defy+ stock sbf on a regular Defy and not a single advantage.
1. If you own a green lensed Defy (SOC module) you can kiss your camera "Good bye"
2. People have reported issues with wifi connectivity
3. You can NEVER go back to Froyo again
4. If you are still under warranty, you can kiss it "Good bye" too, as 2.3.5. was built for Defy+, not Defy and your warranty will be void (remember - you can never go back to Froyo)
5. People would kill to be in your shoes and be able to flash and use different custom ROM's, based on both Froyo and GB kernels (downgrade is not an issue with custom ROM's, unlike stock ROM's)
If your defy is a green lens one. I suggest use GGL rom. This based on 2.3.6 GB. And totaly perfect with defy. I use this one. camera working too.You can go back to 2.2 froyo.
1. You should have a rooted defy.
2. You should instal clockworkmod.

hello friends,
I'm the new guy here,but I used the defy+ nearly half a year.And I always use the Qrarx's ROM from the CM7 to CM10.
In here, I read lots of threads about the defy's ROM, and found that there are two Kings ,Quarx and Eps3.
they gived us lots of wonderful defy(+) ROM,such as ICS and JB which the MOTO didn;t update the OS.
NOW I don't known the diffience between the Quarx's and Eps3's rom.
sombody can explain it for me?
Thanks a lot!~
basically its the same rom, only difference is that epsylon mostly builds for froyo kernel (defy, mb525), and quarx for gingerbread kernel (defy+, mb526). of course being two separate developers, they probably have different bugs. but the functionality and feel is the same, as they both port the official cyanogenmod rom.

Thanks a lot !
My phone is Defy+, seems I choose the right guy, Quarx!
And I will always focus the Quarx's ROM.
:good:
For CMX, Quarx and Epsilon are planning to use a common repository, so I guess they won't have different builds in the near future.
