http://mygadgetnews.com/2011/01/11/meego-and-ubuntu-ported-to-nexus-s/
this made running ubuntu and meego on a nexus.
can this method be used to install android 2.3 on a phone running android 2.1,
especilly in the case when upgrading is difficult because of kernel and locked bootloader (like motorola devices) ? excuse me if it is a silly question, i'm not a coder.
The Nexus S is a completely different phone built by a coompletely different manufacturer.
So what can be do to/with it has no bearing on what it's possible to do to/with the Defy.
Motorola encrypt their bootloaders, meaning it's basically impossible to produce a Gingerbread ROM for the Defy until an official one is released/leaks.

Hi guys. Sorry if this is a dumb question, but how do I install the 2.3 Android while i have the 2.2? Where to download and how to install it?
You can't as it's currently for the Nexus S and soon to be the Nexus One
You can get a cutom made 2.3 ROM by looking at Oxygen in the ROM forum
Thanks. Well since I don't know the risks of "rooting" or installing custom roms, I want to ask you: is it worth it? Do I lose my phones warranty?
At this point the risk of rooting is minimal (but still there is a risk) and there are good tutorial you can use. Especially this one: Turkeys' Ultimate Guide to Root Desire.
Technicality you lose your warranty when you root your phone but there are ways to revert that. However that is not possible on every phone and depends on the branding and software version.
There is some great development on the gingerbread roms, but they don't full work jet, so at this point I would not root my device just for a gingerbread rom.
On the other hand there are also enough other great froyo roms to try out.
But first thing to do is write down your software info and check if you can find a matching RUU here.
hi guys,
i am planning to buy a motorla defy, and i have some background on rooting and installing custom roms with my current samsung spica on cm6.1. but with the locked bootloader and stuff, it seems the method for modding and installing custom roms for the defy is not as straight forward (rooting should be easy). i have read through the wikis and guides and mostly understand everything, but i have questions that i want to ask still. i am about 90% sure about everything i read but i just want confirmation
1) clockwork recovery is the only custom recovery available for the defy? also it's not the official clockwork recovery right? so i can't install the app from the market?
2) does the locked bootloader mean we can't change the kernel? we can install custom roms through nandriod backup but we still have to stick to stock kernels?
3) is there an official froyo stock rom already out? or are they just froyo leaks? also, are all the froyo custom roms based on stock froyo base?
4) what does vsel mean? i know its an important setting for overclocking/underclocking the defy
5) what does sbf mean? is it similar to radio?
6) rdslite is like ruu (flashing software/tool) that comes with the defy?
thanks in advance. i'm really looking forward to this phone given the specs and the price. i just want to know how easy it is to mod it
Hello I have a Defy already and I played with the tools you say so I can try answering some of your questions. Please note that I am no expert and I might not be correct on all.
Q. clockwork recovery is the only custom recovery available for the defy? also it's not the official clockwork recovery right? so i can't install the app from the market?
A. An app very similar to ClockWork recovery exists for defy. It is till now the only one I know. I'm not sure it's on market however is available in this forum. Note that this app can not replace stock recovery.
Q. does the locked bootloader mean we can't change the kernel? we can install custom roms through nandriod backup but we still have to stick to stock kernels?
A. I think you are right. We are limited to stock kernels.
Q. is there an official froyo stock rom already out? or are they just froyo leaks? also, are all the froyo custom roms based on stock froyo base?
A. The only official froyo I know it is the china version. However the recently leaks of some development stage froyos for US TMobile and UK are pretty stable and ok. There are custom Roms (Nandroid backups in fact) based on these leaks but not only. There are older custom roms based on official Eclair releases.
Q. what does vsel mean? i know its an important setting for overclocking/underclocking the defy
A. VSel comes from Voltage Select. There are ways (even an app) to set the voltage for the processor when it is in any of the states (300 / 600 / 800 MHz by default).
Q. what does sbf mean? is it similar to radio?
A. Have no ideea what sbf stands for but it's a format for things that can be flashed via RSDLite. I have a feeling that RUU updates from motorola are in fact an exe + a sbf file. There are lots lots of things available as sbf files: Full firmwares, Bootloaders, some fixes.
Q. rdslite is like ruu (flashing software/tool) that comes with the defy?
A. I think so. I think RSD Lite is a tool made available by motorola for the developers and stuff.
I recommend this phone. I came to this one from HTC Legend that had all the thingies unlocked (S-Off etc) but I do not miss them. Indeed without a custom bootloade chances to see Cyanogen Mod or others are indeed low. I hope I was able to help a little.
thanks a lot mcm_xyz, you confirmed a lot of stuff for me. from just what i read it looks like defy would be the perfect phone if not for the locked bootloader... can you list what is possible and impossible with the locked bootloader? does it mean we have to wait for official support/release either from motorola or cyanogen or other devs to get a hold of different types of roms?

I think this is how it's done by the majority of the cooks nowadays. They get an existing working rom and they build aroud the existing kernel in there. However I think Cyanogen is way higher and they build everything themselves. I think they have a core and different branches for different types of phones that include mainly hardware specifics of the phone. But they are based on their custom kernel so no Cyanogen for us at least yet. but do not worry. steps are beeing done towards an unlocked bootloader on Motorola phones.

thanks for your input dude!
This is yet a question i want to ask everyone. Last night what i thought about was if we could sign apk files again after they had been unsigned, why can't we sign 2.3 sbf?
1. Port Gingerbread to defy and i believe it'll be buggy because that's not an easy task to do.
2. Sign the sbf just like we can sign 3rd party apk?
3. Flash the rom
I don't know but i got flared up when i saw that Htc desire is to get 2.3 by the spring...and i had seen desire's performance compared to defy and it's nothing. Defy beats desire if they're both compared with 2.2 rom.
I'm a newb at all this and this is what i thought...but i would like to know the reason why gingerbread can't be ported and signed even though we have a locked bootloader. Can't someone create an exploit or something to bypass the security checking?
you can't sign a custom kernel
I really would like to use MIUI for my HTC Wildfire, which is why I rooted my phone in the first place. :/
It wont install / it wont boot.
Surely you must have seen the available ROMs in the Dev Zone if you were rooting only for MIUI?? MIUI being such an eye candy ROM is obviously designed only for devices which have hardware capable for it.
Haha, I looked up MIUI and thought that it was really pretty and found out it's only for rooted devices. I spent more time trying to figure out how to root my 2.2 device than even bothering to check if MIUI is suitable for Wildfire. Thank you for you reply.
Hey all,
Rumour is that handsets with 2.3.3+ will eventually go to ICS.
Do you think this will include Defy+ ?
Kind regards
Only one Word: Motorola
It is very likely but it will b a long time before that happens
Sent from my MB525 using xda premium
Well yes, the main issue could be *Motorola*
Even the new RAZR is looking at Q1 2012 for ICS.
Well right now the Defy i have now with Walter's Defy+ stock rom will have to suffice
It is a possibility unless there is a Defy++ in the making.
Sent from Android 2.3.7
does it really matter whether there will be an official or not? the cyanogen team will start working on cm9 (ics) as soon as the source is available, which will probably happen in a few weeks. and since the defy is officially supported (and all devices capable of running gb will be able to run ics), we will get official cm9. the question is, with which kernel, because as long as the bootloader is locked, we will have to stick to froyo kernel. no idea how that effects things... :/
sent from my cm7.1 defy...
Motorola RAZR will be the
first phone to incorporate Motorola’s
new bootloader solution. http://ausdroid.net/2011/10/21/motorola-razr-to-be-unlockable/
"Motorola. said they
were working on a bootloader solution that would allow
the unlocking and re-locking of the bootloaders on their
phones later this year. "
So there's still hope for defy/+'s bootloader .
Well, unlocking the Bootloader.
But I think the Defy won't have ICS, due to the old kernel.
just thinking.
As far as trusting Motorola for updates, I wouldn't start getting my hopes up. You'll notice the original Defy is still at 2.2 and the Defy+ hasn't got any updates at all.
Our only hope is CyanogenMod and the likes, and the Defy isn't on the high-priority list of any of them. By the time, and if, it comes out at all, we'd all probably have fancy new phones anyways.
Defy original came with 2.1 and got one upgrade to 2.2. It is logical that defy+ get one upgrade too...
ICS will work with froyo kernel 99% sure. Difference between froyo and ginger kernel is security fixes, no major updates, new kernel 3.0.1 is the high-end Linux, if Motorola unlocked boot-loaders it's a big plus about using last kernel innovations.
i hope motorola releases the official gingerbread for our defy because isn't acceptable that we are at froyo yet
^ Motorola confirm that 2.2 is latest update for Defy and Kernel of Defy+ is the same as Froyo 2.6.32, update is not needed. Google was make equip for updating all phones (when is possible) to run 4.0, but was a fake, maybe ?!
we're waiting cyanogenmod team
