For droid bionic: custom rom such as Eclipse and Liberty, are they based on the stock moto rom or based on CM7?
wow this is a premature and unneccary thread go to adroid development stickied rom/scripts/hacks etc.. it has a line up if they are 902 based 901 896 etc... click on the link it will probably bring you to rootz wiki and the rom will tell you if it is stock etc.. kinex is stock based eclipse has customized but has parts of blur still in it but is mainly aosp.
search button is your friend
Sorry, if you feel this as unnecessary thread. I did mention the question as newbie question. I did look/search & couldn't find the answer I was looking for. The reason I asked is that whichever custom rom I look, it REQUIRES some specific version from moto original rom such as 902, 901, 893 version to be compatible with that particular rom. That's why I though those custom rom are based on moto rom. I just want to understand why can't we just flash to custom rom like CM7 on bionic. If you can give me a clear answer it will be great.
Thanks in advance.

The reason that you can't flash CM7 over top of stock is this:
Think of CM7 as an "update", since we are on a locked bootloader.
Now, we can't change the kernel, which is the core of the Android OS.
So, with CM7 we can't have everything that CM7 has to offer.
So devs port the CM7 code so it will work with our kernel.
This means that whatever kernel version the dev uses to write CM7 must be installed before you flash CM7. Otherwise you have a ROM with a kernel that is not compatible with it (and that is not good). It would be the same as flashing a ROM meant for an HTC phone to a Motorola phone like ours. It just wouldn't work.
Thanks, Priddyma, for explaining .....
So, basically, custom roms for bionic such as Eclipse & Liberty are built based on particular moto locked kernel, right? Is it also the case with new bionic roms with ICS features, are they built around the .902 kernel with ICS features?
Another question, when we do OTA official updates, for instant update from .893 to .902, the official updates (from Motorola) are capable of flashing to different kernel? In other words, is it possible to flash kernel (If you are Motorola dev & have the unlock code)?
What I want to know is that in the future, if Motorola is nice enough & could release the unlock code so that we can flash bootloader/kernel to whatever we want.
It's already been stated by verizon that it's them locking the bootloader, and not moto.

ok first i am a total newbie.. planning to buy my first android phone and i am interested with the unlocked milestone as it seems to be the cheapest flash 10.1(i am very interested in flash too) enabled android phone out there.. i read the bootloader is locked... which means you cannot load custom roms on it..
i also read that using 2nd boot or kexec, u can load custom roms on it... my question is with these 2 methods, can u load a full custom rom(e.g. android 2.3) on milestone or is it still very limited and u must wait for actual official android 2.3??
i always want a gadget that u can fully customize...
IN SHORT, STAY AWAY FROM MOTO, AND NO OFFICAL 2.2 ROM MEANS NO FLASH SUPPORT OFFICALLY. TAKE A LOOK AT MOTO EURO FACEBOOK.

Moto locked up te bootoader, that means you are not allow to use unoffical kernel, and no full custom rom

the 2.2 update was delayed again until q1 2011. im seriously thinking of returning it for a refund.
http://forum.xda-developers.com/showthread.php?t=815595
so this custom rom is a fake froyo? No flash 10.1?
You can't say that is a fake froyo, as it is a real froyo with Flash support, but all froyo mod are using the leak 2.2 beta kernel, which still had many bugs. and we can't use a custom kernel as MOTO had locked the bootloader, so back to the how hackable question, Milestone is not very hackable, because we can't use custom kernel and that means many things can't do.
So, I am thinking about putting custom ROM to my SGS i9000. Its currently with Android version 2.3.3.
I've been reading through this forum and most of custom ROMs are for Froyo? I mean many of instructions say that you have to be on Froyo if you want to use this ROM.
My question is must I get back to Froyo somehow or is it possible to put custom ROM for my current Android version?
Sorry about my noobishm. And I hope my english is good enough for you to understand.
Many thanks

Wrong, most of the custom roms are based on gingerbread. Stay as you are mate more excitement to come

You can always switch between 2.2. and 2.3.x. The only thing you need to pay attention to is that you need to flash the proper bootloader.
Flashing a bootloader is risky insofar as if the bootloader is not flashed properly, your device is thoroughly bricked and can only be revived by Samsung (or someone with the proper hardware). Furthermore with Froyo you may erroneously flash a locked bootloader which would make you stuck with that one ROM for the rest of your device's life, so make sure you only flash unlocked ones.
This said, there are actually few ROMs out there that still rely on Froyo (Insanity comes to my mind as an example). So you probably won't need flash Froyo just because of custom ROMs. Simply follow DonVito2020's link and choose a Gingerbread one.

Look at the fifth comment. Nice instruction, but is it safe one?
I'm gonna try it if it is.

It looks like a good how-to. Whether it is safe or not I cannot tell without looking into the files, however since the post links to Gingerbread ROMS, not Froyo ROMs, it is most certainly safe, as far as the bootloader is concerned (at least I have never heard of locked Gingerbread bootloaders for the Galaxy S).
Though since you are already on stock Gingerbread, take a look under at the Baseband Version under Settings - About Phone. The last three letters will tell you which release of Gingerbread you have. In my case the baseband is I9000XXJVR, so I have JVR.
If you already have JVQ or JVP, you can flash the kernel and then Darky's Rom directly. Just don't forget to backup everything.
New to android world and looking for first rom. On stock Froyo 2.2, rooted, clockwork installed. Which rom can be installed without Odin? Do kernels have to be installed separate, if so, is it before or after rom install? Looking for sense-like ui.
Thanks!!

If you want sense go buy a HTC lol. Odin is going to be your bread and butter since its the easiest way to flash to stock and flash kernels. Most roms can be installed without odin though. Go to the dev page and look around at the roms and make your choice. Remember Gingerbread needs new bootloaders (except Cyanogenmod and Miui) and as always read read read.

Hi,
Longtime reader of this forum, never really posted so I can't post this in Android Development for Milestone. I believe I need to introduce my question with valuable information before asking it.
So here I go, I have a Motorola Milestone (A853) originally from Telus that I have unlocked and am currently using it with MIUI 1.9.23. I have used other ROMs on it including Kabaldan's CM7. Just using MIUI as I find its day-to-day use more convivial even at the cost of performance and battery life. Anyway, my current kernel version shows:
2.6.32.9-g11068ed
Click to expand...

I believe this changes depending of which rom you use but I may be wrong. Now my question is: is there any advantage for me (performance/stability) to flash a new kernel version with a full or service SBF (to avoid wipe) over at And-Developpers.
When I first rooted my phone and flashed using RSD Lite I used the Telus 2.2.1 kernel with vulnerable recovery. Would changing for Claro Brazil or Africa and reinstalling a custom rom such as MIUI or CM7 do any difference on stability and/or performance in your opinion?
I have seen users praise the Africa and/or Claro Brasil kernels as having fewer if any DSI related issues and I am tempted to try them but am not really sure if it is worth the hassle (to possibly wipe everything on my phone and start over). I would appreciate if anyone had experience or knowledge on this matter.
Thank you.

Each ROM has its own kernel, but it's all based off of the stock 2.2.1 kernel. Although the kernel versions may look different, they are all based off the same kernel. And because the Milestone has a locked bootloader, you can't flash kernels. So, basically, you're stuck with the kernel that you get with MIUI or CM7, etc. People only praise the Africa kernel for Froyo, as it has the least amount of DSI errors. The "kernels" in custom ROMs are much more optimized than any stock kernel you might consider.

Before you say that there is no bloat in all the custom ROMs, I have ran a few of them and they still have stuff like Backup Assistant running in the background and I would love to not have to clean it. I would love the stock launcher and AOSP (of course it's based on the Verizon ROM since CM7 isn't stable but just for the drivers and stuff only) as much as possible and even the stock Gingerbread look and feel. Is that possible? Or at least remove all the Verizon software?
Check out liberty rom..its very aosp like and although its just a blurless rom its still nice and I don't think there's any bloat in it but hey I could be terribly mistaken. There's a link in the development secotion under the thread 'liberty rom now on d3' to the rootzwiki page thazt has the download
/Droid3
Pedwards3x has a deodexed/debloated 'stock' ROM at RootzWiki (sorry, can't post links just yet) you might wanna check into.
Thanks guys.
