[Q for DEVS] Custom ROMs compatibility: Defy+ and Defy XT535? - Defy Q&A, Help & Troubleshooting

While this question has been asked in a couple of threads, it has not been answered or received attention.
While many of the custom ROMS claim to work with both Defy and Defy+, there are a lot of doubts about their compatibility with Defy XT. For those who haven't heard of the phone, its a Asia version of Defy+, but comes with a secondary camera and a lot of internal hardware mods.
Keeping in mind that the XT has a different chipset (Qualcomm MSM7227A) compared to Defy+ (TI OMAP 3620), possibly a different processor, will we be able to use the custom ROMs developed for Defy/Defy+ to upgrade XT?
I'm pretty sure, being a limited release the development scene for XT would be much slower than that for Defy/Defy+. Even now i couldn't find many firmwares specific or confirmed to work on XT.
If the compatibility doesn't exist and considering that the front camera is not an absolute necessity, is it worth buying the XT? I'd rather have a slightly older hardware and be able to install cool custom stuff, than to get stuck with the stock ROM.
Also, i couldn't find whether and how better is XT hardware over the Defy+.
I'd be happy to see some DEVs comment on this, as it has been asked over and over and help us make the right buy decision. Thank you so much!

I am also waiting for a custom rom for my defy XT

I would say go with Defy+ rather than Defy XT if Front camera is not a concern for following points.
1. Defy+ has 2GB of internal Memory out of which around 1.4GB is available for apps where Defy XT has very low.(I've read it but could ot find reference now will post if found)
2. Defy+ have better battery than Defy XT (1700 vs 1650)
3. Looks of Defy+ are far better that Defy XT
4. Custom ROM avaiabilty is far better for Defy+

[Q] SBF/ROM req for green Defy

Hello,
I'm looking to finally take the plunge and flash a custom ROM, but I'm a bit lost in all the possibilities. I have a green Defy flashed with stock 2.2—what would be the best upgrade, bearing in mind the following criteria (ordered by priority):
1. Stability
2. Battery life
3. Speed/performance
4. Appearance
Also, I'd prefer it to have the least possible applications/services/clutter installed while still running stable, so I can work my way up from there with the apps I need.
Any input would be appreciated.
Try cm7 for a while start with the stable and then try a few nightlys, it will get you used to flashing, then try cm9 and you will see how good it can be,
Green lense defys don't get flashed with sbfs after froyo, you will just have issues, if you break something then just reflash your sbf of froyo and you'll be fine
teamwork makes the dream work
Thanks for your reply. Forgive my skepticism, but I was under the impression CM7 was all about adding functionality and features—how is it going to make my phone lighter or increase battery life?
more free ram more multitasking..android 2.3 gb ..you can yourself give it a try and have a look at your battery stats..+ you get firmware update! and its ultra smooth then defy froyo 2.2.1 ..much much better .. you can play 720p hd videos too ,,flash is much better in GB..then on froyo..try it out and feel the difference..good luck!

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.

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.

[Q] Need help choosing ICS rom...

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.
Sent from my MB526 using XDA
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.

[Q] Upgrading to 2.3 on Defy using Defy+ official rom?

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 ;-)
Sent from my MB525 using XDA
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.

ICS - JB ROM for our Defy Mini (XT 320 - XT 321)

Hi there! I have just rooted my Defy Mini, which has been a very long awaited thing to do.
Now, I wonder if there is any activity on bringing newer Android versions to the device (since as it seems, Moto does not intend to do so officially).
I have found this:
hackandbots.blogspot.gr/2012/12/rom-motorola-defy-mini-xt320-mane.html
but I am very sceptic to try it on my device. Has anyone thried it?
Is there any prospect for having a ROM for trusted sources, such as CM9 - CM10 for Defy Mini?
The blog post I pasted above, is almost a month old and it only has 2 comments (in the 1st one it also mentions overclocking!)
That's fake, it was posted here and then deleted.
And no, i think there are no projects atm as there are no devs for xt320.
What about porting a defy or defy+ ROM?
Would that be so difficult for someone with technical knowledge?
I know there are not many defy mini developpers, since it is an entry level phone and all the geek guys prefer Samsung Galaxy's etc, but there always is hope left...
Someone did manage to root it, after all!
So my congratulations to the root method finders, I hope there will be some CM dev that shows some interest in our cute device!
well...
isn't the defy mini not just a defy with red lens and less memory and slower cpu?
would even trying to flash a defy rom brick it?
what would be the chance of this working or is even thinking about it insane?
Defy Mini uses different cpu, and gpu i think, has lower resolution, so no, i dont think it would work.
so... is there something like a generic android rom?
or would you have to build one from source...
where do those custom rom devs usually start with?
i mean, not talking about modding the stockrom from the vendor but when someone decides to make a new rom for a phone for where there is no reference.
like a jellybean rom where the vendor only provided a gingerbread rom..
i might consider giving it a try but have no clue where to start.
There's a link for the root?

new stock roms
I just got a new Motorola Defy Plus phone with gingerbread 2.3.x stock rom.
Where can I find a Motorola Defy Plus ICS or Jellybean stock rom?
Not Cyanogenmod or AOKP/AOSP.
Is there any such thing as a stock ICS or Jellybean for Motorola Defy Plus rom?
So far all I see is cyanogen/aokp/aosp ics and jellybean roms.
Does this means that most likely there are no stock ics/jellybean roms for the phone?
Thanks
And why you are posting in DMini thread? Second, there is no stock ICS for MB526 (no leak, nothing) & never will be, because moto abandoned Defy (including MB526), so if you wanna that on your phone would be newest android, you should buy Samsung or Nexus phones...

Any news on a custom rom for the Defy Mini?? I'm on the edge on starting to build my own rom soon.
It's very hard to port a rom of razr d1 (JB) to defy mini? Both are Dual SIM and have the same resolution. It's very disappointing not have custom roms to defy mini. Someone can support us?
Porting CM7 to Defy Mini
Hello to all.
I have a rooted defy mini, with bootloader enabled.and some free time.
I'm about to start working in a port of CM7 to Defy mini. But I have a question, and I would like to some support: Wich is the best option: work on a Defy rom or the Lg Optimus L3 rom, which has almost the same hardware specs of Defy mini?
My motivation increased as I recently bought an L3 for my wife, to replace her old dead phone, and installed CM7 on it. Marvelous! So, I got a little jealous, rs.
Oh, and if I'm posting in the wrong place, I'm sorry. I'm an esporadic visitor to XDA - guess I'llo become more present here...
