[Q] Question related to kernels - Defy Q&A, Help & Troubleshooting

I own a Defy red lens presently on cm7.2 rc3. Base sbf is froyo.
I heard a lot about defy+ being more energy efficient because of its Gingerbread.
Now for my doubt- cm7.2 rc3 is based on GB kernel.
1. Does that mean that installing cm7.2 rc3 over froyo is as good as installing Gingerbread sbf & then installing cm7 for defy+.
2. What if I want to install defy builds later instead of defy+? Flash cm7 kernel I suppose.
3. In essence, is installing cm7/cm9 kernel as good as flashing froyo/ GB?

[Q] CM 7 and MIUI (official vs unofficial) + Flash Question

Hello all,
I'm posting this thread because I'm getting a little confused after all this reading. Basically, I just need some confirmations.
Lately I've been reading a lot on CM7 and CM9 but now I'm also starting to get interested in MIUI.
I've come across:
WIUI
MIUI Pikachu edition
MIUIandroid.com
Motorola Defy MIUI.us
I underlined my 4 questions for your convenience.
So I have some Questions on Custom ROMS
As you can see, I've looked for an official MIUI build for the Defy but I can't seem to find an official MIUI build. These listed above are all 'edited' by someone.
Could someone explain what i'm (probably) overlooking? Is there an official MIUI?
At the moment WIUI and Pikachu edition look very nice.
I currently have a Bayer (aka red lense) Defy (MB525)
stock android 2.2.2 on 2.6.32.9 kernel.
Systemversion: Version.34.164.3.MB525.Retail.en.FR.
Build number: 3.4.2-164
Which means I have a Froyo/Defy/'CM7' Kernel
CM7 and MIUI(GB) are all meant to be flashed on this Froyo/Defy/CM7 kernel, am I correct?
I find the '(GB)' with MIUI rather confusing, it's android 2.3.x but it's running Froyo kernel/Defy/CM7 kernel and not a GB/Defy+/CM9 kernel.
Now, the flashing
If I decide to flash a custom ROM: CM7.2 or a version of (GB) MIUI:
Can I just flash MIUI or CM7.2 RC1 on my current build or do I need to flash CEE or Nordic 2.2.2 first? I prefer not to lose my downgradeability.
I assume a flash from my current build to CEE or Nordic via RSDlite will result in an efuse so I can't flash my full 34.164.3.MB525.Retail.en.FR SBF anymore, or am I mistaken?
I currently have a full SBF of my original stock ROM, just in case.
Kind Regards, Config.

I have a Defy with bayer camera module, all I did for installing custom roms was root, install 2nd init, reboot to boot loader and wipe all data/cache (this is the first step in any of the mentioned ROMs, but please read the respective step-by-step tutorials in case I missed something), and then flashed the desired CM or CM-based (like MIUI) rom
The defy versions all basically run over froyo kernel, as it's the last official kernel released for the device (GB kernels are either leaked or belong to the defy+) , I never flashed a newer one and have tested quite a few MIUI and CM versions, including:
MIUI.us (oficial US MIUI adaptation team)
MIUIandroid.com (British team)
WIUI (Wajk's multilanguage version, and also has an ICS test version, that I also tried)
CM7.1 and Epsylon3's CM9 for Defy (in beta, but more stable than WIUI's ICS for Defy)
I don't actually know if flashing a newer kernel would be any use for these roms, I know defy and defy+ (different kernels) roms are not interchangeable, so I wouln't bother with it unless you are flashing a full sbf rom (in which case I have no experience with)

Thanks,
If I may ask, What ROM would you personally recommend?
Does anyone know the answer on my 2 last questions?
Config
From the ones I've used for a while, I suggest the official MIUI (gingerbread) if you wan't to be safe and CM9 if you want some ICS sweetness and feel good about dealing with the perks of a beta release. Once we finally have an official (or at least a stable/less buggy alternative) version of ICS MIUI for defy, I'd go with that, definitely

With official MIUI, do you mean the US version or the British?
For what i know, official miui is from chinese site miui.com. All others have some modification. More o less, all of them came frome miui's official releases. In my case, wiui is the most stable i been using since long time ago. I'm waiting for stable ics miui too cause there aren't an official rom from miui.com for defy. And the reason for that is because cm9 it's still in beta, and miui is based on cm project. All v4 around for defy are just port from others device's roms and have a lot of bugs, especially mobile data. As we know, motorola made our defy whit a locked bootloader whit froyo kernel in it. For that reason is more easy make a rom froyo kernel based. But isn't the unique option. there's a rom maded by walter 79 whit gb kernel that have excellent results, especially In battery life. Cm9 whit gb kernel too.
One more thing: miui (not v4) and cm7, are both android 2.3.x

The really official one is the chinese, the others are, as ldiomedi said, translation/adaptation teams. Some apps may be added or removed, but usually nothing you would notice. I settled using the british version because the phone numbers where formatted the same way as in Brasil ((xx)xxxx xxxx) and the brazillian team was lagging behind updates. WIUI gathers language options, but I don't know about other adaptations.
So if I'm correct:
If I would like to use MIUIandroid I have to get the newest build here, the MIUI.US over here and WIUI just at the forums.
My SD card is getting a bit small, it's only 2gig.
So before leaving my stock ROM I would like to switch it.
Are there any extra steps I should do because of the SD-card switching?
You don't need to keep the rom in the sd after installing it, use each one a bit to see which you like better. Install the definite one and then delete the roms from the sd card, you can always redownload if you want to change again latter.
I know I don't have to keep those files on my SD-card.
It's just that 2gb is getting too small to store some photos and files.
I would go for the GB WIUI rom as it has both nl and fr translations. I tried it in the past and the translations were good. It is also optimized for the defy. The others handle many different devices.

A full SBF with a nandroid backup should do for an 'insurance' I hope.

Why FroYo Kernel?

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.

Any custom rom for defy DFP-231 bl7

hey i successfully rooted my defy plus dfp 231 bl7 i used coustom recovery v5 to install cm9 by fuzz "swank" it's cool but has bugs like no "move to sd" and evn shows insufficient storage error.
is there any solution to that.
or any other roms suggestion. :laugh:
Custom roms:
CM9 defy+ nightlies by Quarx
CM9 kangs by FuZZ (based on above)
CM9 defy+ nightlies by Epsylon3 (not preferred. Eppy focuses on the defy builds (froyo kernel))
CM7 defy+ nightlies by Quarx
CM7 whiterabbit plus edition (based on above)
CM9 kangs by FuZZ (also based on Quarx)
MIUI Scotland defy+ (2.3.7) brand new MIUI android 2.3.7
Various defy+ MIUI v4 builds
Various modified stock roms (e.g. ms2ginger)
Sure there are some more, but I don't remember them all. These are the most important ones

would they work for dfp 231 bl7
I had some strange problems with proximity sensor with CM7 (and BL7).
Ms2Ginger is running just fine at the moment :good:
As long as you don't install some Defy roms (with Froyo kernel) everything should work - with or without bugs

No. I just wanted to list a lot of roms that will not work on bl7 because I don't like you
Of course they will work! Well, I haven't tried them on bl7 since I'm bl6 with bl5 defy+ kernel, but these are all defy+ roms. Good luck! Just remember not to flash kernels e.g. Walter's kernel as it's for bl<6 and will brick your phone!

Better Kernal for Red Lense Defy

Hello Guys,
I am a Red Lense defy user... I am currently running with Epsy's 17th June CM9 Nightly with CM7 Kernal.
I am now planning to flash with Defy+ rom woth CM9 kernal of 6th July.
Is it really advisable to have GB kernal for Red lense DEfy? What are the advantages of having GB kernal over Froyo.
Also whose ROM are better Epsy's or Quarx? Or rather want to know the diffrence between them
Thanks in advance.
Regards,
Sameer
about cm9 roms, Quarx's and epsy's rom are no different from each other.
Quarx have a defy+, so his defy+ builds are more stable... and Epsylon have a defy, so his defy builds are more stable.
well, this theory is based on my perception, but personally i use epsy's defy 11.07 build, it is stable, smooth(mostly),battery friendly and fully hardware accelerated.
but the choice is your's..
and about defy+ kernel, you have to flash one if you wish to run defy+ build on red lens defy.Otherwise, it won't work
OK i will try Epsy's 11th Jul ROM.... I will just need to wipe Cache and Dalvik right? No need to wipe Data.
I was having some freeze and then soft reboot issues with the ROM is am currently having.
Yes, you are good to go...
Are there any advantages of having GB kernal over Froyo kernal in Red Lense Defy?.
