File system/partition layout? - Samsung Galaxy Nexus

I'm wondering if the partition layout/file system format will be mtd/yaffs2/ext4 like it was with the nexus s?

How to brick Gnex?

I want to test something, and I have done it before on Skyrocket Galaxy, but forgot exactly how.
I think I used Odin to flashed a modified pit file, and I successfully bricked the SR.
I can't find a gnex pit file to test.
http://forum.xda-developers.com/showthread.php?t=1586807
The rom there doesn't have pit file. I can't seem to able to open the img files in there.
Do you guys have a PIT for me to play?
I think I add "1" in one of the partition address in the PIT for SR before.
Thanks
I found this.
I will test it soon.

You sound like you have experience.
I am going to brick it that way and unbrick it afterward.
I'm not sure how to brick the GN, but maybe you can try that format the whole internal flash memoryvia ADB, and unplug while you flashing this...

That didn't work for me last time for Skyrocket.
I could still go into Odin and flash again.
Need to go deeper into low level like pit or before odin.

You are coming from an HTC device, yes?
A bad radio flash on HTC devices will certainly brick your device.
That is not the case with Samsung devices though. I've seen some individuals with bad radio flashes, and fastboot still works fine to flash a new one.

I don't know if if the Galaxy Nexus suffers from the same issue as the Samsung Moment, but with that phone, flashing a boot.png (on the GN it's the very first static, black and white 'Google' screen when the phone turns on) larger in size that the existing one, or having too many colors, etc would cause an instant perma-brick. I don't know if we're to the point with the GN where we can freely flash that sort of thing, but I know it worked (didn't work?) on the Moment.
The first post here has the list of guidelines for flashing boot.png images that were discovered trial-by-fire by Moment users.
So, are you guys saying it's next to impossible to brick the Galaxy Nexus if just flashing the basic stuff?

You have no idea how relieved that makes me.
I come from an HTC Nexus One and I never once flashed a radio on it, and I didn't wanna mess too much with bootloaders as an incorrect flashing of the two would acquire a brick.
I'm only on user-level (and flashing, of course) so I don't think I'll ever manage to brick it.

I wasn't trying to be funny, I was making a point. Installing Gingerbread is going backwards, in aesthetics and functionality. I'm sure if you really want gingerbread so bad you can find a GB theme. That way you have the look and feel of GB with the improvements of ICS. Or install a different launcher or custom rom that is to your liking.

What did I just read here?
I get ur point and I get what's the point in doing it.no it doesn't make sense but I'd like to have it.just making a more sense based or gengerbread Based rom would be more ideal than actually downgrading.or like u said a theme or something would be a good alternative.
Wouldn't downgrading require you to add aftermarket menu/home/back/search keys to the Nexus?
It's hard enough trying to find a case that fits the extended battery.
[insert mandatory 'why not Cupcake?' joke here]
most likely it would be possible since the gn runs pure android. the only issue i could see, besides the soft keys, would be the drivers. no gingerbread drivers exist for the galaxy nexus. youd either have to write/compile the drivers from scratch or create a hybrid gingerbread/ics rom(which would defeat the whole purpose of running gingerbread since it wouldnt be gingerbread anymore).

Oh really? do you pay them a salary every month? devs do this as a hobby they dont owe us anything nor do they have to share any of their roms mods or themes with us but they do.. could you try being a little grateful..and not act like a snotty spoiled kid that think that ppl are his servants.
Why is everybody ****ting on this idea? I think its awesome especially with the T-989. You can have a stock rom with WIFI calling when you need it, and cyanogenmod or whatever for the rest of the time.
You are almost a year late for the party...

Reason why Dual Boot is good
There are reason why dual boot is good
1.Don't need to worry hard brick(flashed to external sd, not in device):fingers-crossed:
2.Easy to test ROMs for developers because they can flash to sd card and boot from sd card. Also, developers does not need to mess up with hardware.
3.For people afraid of flashing ROM, dual boot is nice choice for them.:laughI am afraid of Flashing ROM also)
Sorry for my bad English.
Now this is the definition of dual boot http://m.androidcentral.com/samsung-ativ-q-puts-windows-android-single-tablet

That isn't exactly a dual booting app, but an app that overwrites your /system, /data and /cache partitions if I remember right. A true dual-boot mode would need to be baked into the kernel so that it can mount different /system, /data and /cache partitions on your device.
As was stated in an earlier post, it is nice because you can have some of those on your external SD card or internal SD card and have a failover in case something goes wrong with your ROM (ie your primary boot is your DD, your secondary is a non-DD or a new one and you hold vol+ while booting to go into it... usually it is a hotkey to boot secondary OR a menu like GRUB with a timeout). The problem is that in order to get that working, you need 2 partitions for your /system drive (one for each ROM). Most phones that support kernel-level dual boots have a partition we can borrow space from for the second /system (I believe the I9100 (could have the model wrong) uses partition 9, but our phones have that partition really small). I have looked around on the phone and currently cannot find a suitable alternate /system partition. It needs to be on internal memory as the external SD card mounts too late and you will get various kernel panics if it can't mount /system soon enough.
We COULD get dual boot working (in theory), but it would require stealing space from /sdcard (or /storage/sdcard0... they are the same device).. ie we would lose internal storage space. PLUS it would require some advanced steps preformed from the shell to do that and if you screw those up, you get a nice brick.
At least such is my understanding from reading various threads about dual-booting.
TL;DR: it is possible, but the chance of bricking is high.
Also, if you read the description to that app:
BootManager will not work with Samsung devices that are not listed because of the way Samsung handles the boot partition
and the SGH-T989 is NOT listed. Are you SURE that app works with our phone without screwing up the boot partition (or any other partition for that matter)?
I would love a dual boot feature. I use cyanogenmod and while it's great, samsung roms have MHL and wifi calling which would come in handy.

Ooo... I'm making progress on a dual boot option for our phones (YAY) bad news though is how it will work. If external ad it's present, not from it; else boot from internal.
Good news is that you can size your positions however you like though.
Bad news install steps are complex but I'm working on making it as user friendly as I can.
I'll link my post once I get it working and documented.

Generally, you don't want it bigger than maybe 320 MB. Any bigger and it won't have any space on the system partition, which means no boot or bootloop.
But even thats kinda big.

Thanks for the quick reply! Right now I'm at 612 for the whole /system folder and have deleted every app that seems it is not required. There is probably no way that it ever could fit.
Our EVOS only have 395 mb space, you have a long ways to go.

Start symlinking everything and only keep the essentials needed for it to boot then you can work on adding everything back that's needed when you get it booting.

Damnit, whole "sd-card" just got erased.

I plugged my phone to my computer and put it in fastboot mode to install stock yakju again (I left AOKP).
Without thinking, I typed "fastboot -w" believing it would be a factory reset. Little did I know it also cleaned the whole /data partition. How could I not remember that?
Words cannot express my anger right now
I guess I'm screwed royally now since I had some important and hard-to-find stuff on there?

Not sure how it works with MTP, but you might be able to mount the SD Card partition on your computer and run PhotoRec (http://www.cgsecurity.org/wiki/PhotoRec).
If you're going to do it, do it as SOON as you can, before writing anything else to it.
There's free apps that you can install on your phone to recover stuff from your sdcard. You could try one of them.
I recently did this in my ns4g. I used some freeware called recuva. It worked very nicely
