What is needed to dual boot a device? Some devices like the Samsung galaxy Plus have this feature. Can this work on S3 mini too? Couldn't we install the second ROM not in the root folder but in another folder and then to run it by symlinking the folder just like foldermount does?
Sorry if my questions are considered silly by some...

Not possible for us, for now. Do a little research on xda & you'll find your answer. This has been asked more than once here
What about that: http://forum.xda-developers.com/showthread.php?t=2451661 ? Can someone get it to work for s3 mini?

This one cannot be applied to our phone
First, our partitions point to different devices.
Second, there is not enough space as described in tutorial for all mount points (/system /data /cache)
/system in our case needs minimum 500MB with only UltraSlim_Gapps package installed
/data can be enough only for few apps
/cache on our device have 840MB, 80MB from tutorial isn't enough

Tried firefox for android beta2 today and it freezed my phone, so I uninstall it only to realise that it locked 13MB of my internal memory permanently probably due to bad uninstall. Tried to reinstall it so that I can uninstall it again but it didn't allow me to install again saying that I don't have enough memory (though i still have ~45 MB free internal memory).
Anyone knows where does firefox install to? I couldn't find it in any of the app directory (not in data\app or system\app, nothing in dalvik cache and data\data as well). having 14MB memory locked is really a paint considering how small our milestone memory is.
Please help.
Thanks

1.Do you have a recent nandroid backup? that would be a simple fix?
2. What rom and kernel are you using?
3. Is your phone rooted? Probably yes...All the apps go to /system/app, unless you have apps2sd installed
4. If it's not there and it's not in "manage applications" then probably it's a an error of your rom showing erroneous available space.
Hi,
Thanks for your reply.
1) I am using XT720, we don't have nandroid backup tools yet
2) Stock EU rom and kernel for XT720
3) yes, rooted. I am sure it's not in /system/app (mine has got apps2sd)
4) I guess I'll probably need to reflash the rom to get rid of it then. a bit troublesome but no choice I guess.
Something about the firefox is that if you install it you'll find that the space taken up by the firefox is much bigger than the .apk+dalvik cache+data in the normal app installation path. some portion gets installed into somewhere else which nobody knows where. My friend with a Nexus one try to move it to sd but it simply won't move the whole thing because part of it does not install to the /app.
Anyway, thanks for the help. I'll wait another day or two before I flash it to stock again.
Many thanks

Can you go into recovery? ADB commands actually work as root there.
You also said you have app2sd - I'm guessing the ext version. You can browse around the ext partition if you have something that can read it (like Ubuntu) and delete it from the card as well.
- Look into your /cache partition and delete every download*.apk
- Look into /data/app and look if there is still an apk left
- Look into /data/data and see if a Firefox-folder is located there - delete it!
You can do all this with RootExplorer
Then you should be fixed
Milestone isn't supported. I think I read it somewhere on the mozilla site. There's some known issue logged somewhere
Sent from my Milestone using XDA App
Check if there is any "*.tmp" files under /data/app ?
I was locked some memory due to unsuccessful install of "Pocket Legends", and found out that the apks were stored in both "/cache/downloadfile.apk" and "/data/app/vmxyzxyz.tmp".
Hi guys.
I know that the z4mod can successfully patch a Tab kernel, without any problems (I did it myself, flashed it, and ran it just fine for a few days).
But when I tried to run one of the zip files to switch the file system, everything went nuts and I had to reflash my Tab from scratch.
So I did a little investigating, and as far as I can tell, all that needs to be done to make the whole thing successful is to modify the script in the zip file to correct the mount point names (as they are different from the SGS).
So if anyone around here knows anything about this sort of business, please take a look at it and let me/us all know, cuz it would be GREAT to get z4mod working on the Tab.
Here's the web site if anyone's interested;

Noob question. What's the benefit of running ext2/3 for the internal partitions versus rfs?

RFS is Samsung's partition format (FAT + journal) that is supposed to be better for flash devices. Apparently it is not so good, and very laggy. Therefore people are switching partitions to ext2/3 or moving and linking stuff to SD card with ext2/3 or jffs2 partition.

Could you explain how you came to that conclusion ?
I was not able to locate my mount points to compare with what you did observe, but i guess we should start with that, then ask ryanZA his thought about what you've found.

I'm really newb on linux, but i've read a little since last post.
What if we:
1 - dump mount list from a working SGT (terminal or adb shell -> mount ?)
2 - apply Z4mod then SGT won't boot (i assume it creates /etc/.fstab)
3 - edit /etc/fstab to match the dump in step 1
But, how do we read/write /etc/fstab once the sgt is locked ? using some kind of update.zip, or is there some shell service we could connect to, even if some mounts aren't in the right place ?
Unfortunately, everything I could contribute to this idea was in my first post. I know absolutely nothing about Android development, sadly...
But after reading what Deodexed said about volumes not mounting properly during recovery (he's the guy trying to get CWM to work for our Tabs) it seems that maybe that's the reason that z4mod may not work... If the volumes aren't mounted correctly, it can't convert the filesystems.
Maybe what doloop said might work? I hope so. An SGT running on ext2 would rock the socks off anything else out there. God I want it
I know that there are some devices (specifically the nook color) that can boot from MicroSD. I was just curious if it would be possible to do the same on the samsung galaxy tab 7 (original gsm) and if so, how one would go about setting that up.
if anyone could point me to references, that would be awesome!
Thanks!

There is an app out there called boot manager. It currently works on most htc devices but I am in contact with them trying to get something setup for the tab. Because of the way each company handles the kernel it is an issue. So not promising its possible but it is on the heads of some people.
Yes it's certainly possible to do, though we lack uboot so you'd need to modify the init script in the initramfs to start Android init on a different root device.
What do you have in mind?

I just wanted to be able to use an sd card.to test out some new roms without putting the installed one in peril or losing any data.
Dear co-members and developers,
ther is one question, that i have not been able to find answer for.
Is it possible to unzip/mount the official Galaxy Note rom, then change som apk (for exmaple i want to change the launcher for the TW5.0 one, or replace the originial phone.apk with another one) and after this, to flash it via odin. (i do not wish to root the phone)
Until now, i was able to extract the factoryfs.img, change the format to ext4 via simg2img (one of the tool i found on xda) and mount it (i could transfer files). But now, i am not sure if i can flash such edited file into my note without bricking it (since i change the filesystem little bit (as i understand the transformation process from samsung img to ext4 img).
Thank you for your answers.

Yes you can .But I doubt that it may give you triangle or counter.In that case,its better to root,install cwm,make your files a cwm zip,flash it in recovery....
Thank you for your answer.
The real issues is not really the counter, but the fact that i converted the "official" samsung img to ext4. I ma kind of afraid what that might do with my phone

may be the best way is to root,install cwm,make your mod along with other unmoded files into cwm zip,flash it to check if it works.If it work,then make a odin rom.
It has two advantages:
1.You can find if the mod works.Take a backup before trying the mod and if it dont work.restore the backup.
2.It wont brick your phone in anyway

Thanks for replying. I knew I should have given more information, darn it! I have a rooted i957 LTE that has a really ugly Telus boot screen, Since I don't plan on using this tab for data with AT&T or Telus, I'd like to just get a Samsung (or a generic android) boot animation. I've found some other boot animations in different forums, but I thought that the 7310 would be my best bet because the resolution should be correct without any tweaking. I've seen people posting links to boot files in the past and was hoping someone could do the same with the 7310. Thanks again for your reply.

Here's the situation. I am using the DannoRom_2xx. His Rom has the two qmg files in question located in system>media. I have tried replacing those files with other qmg animation files and they don't seem to want to be replaced. Do I need to replace the files in the ROM and then re-flash the ROM? Actually, I did accomplish part of what I wanted to do (although I'm not sure how I did it.) I did get rid of the Telus screen so now I just have a black screen while my tab is booting. Obviously this is not an urgent problem, I'm just determined to figure out how to do this. It was much easier using zip files on the Nook Color last year. Thanks for trying to help.

How did you try to replace them?
The /system file-system is mounted read-only. It needs to be re-mounted read-write before you can modify it. And then re-mounted read-only in the interest of safety.

Even after setting system permissions to R/W, this is the message I get when I try to move or replace those QMG files that are located in system.

Hmmm. There is another explanation (other than not being rooted, which you already seem to be).
Is the /system/media a distinct file-system? Or a symlink?
(I don't believe the i957 is that different, though)
What does the mount or df command say?
And 'ls -ld /system/media' ?
Also, have you tried doing the mv/cp using adb?

Okay, I surrender! I am not afraid to admit that I am apparently in over my head. I just wanted to replace the current QMG files with some others,and it looks like I have ventured into, what is for me, unchartered territory. I have used ADB in the past, but I don't think I know enough to be really comfortable with it. Samsung's proprietary animation files are way beyond my ability to deal with. I'll be following this thread to see if someone out there who is much more knowledgeable than I, comes up with a procedure that I can understand and actually implement.
Thanks to any and all who have tried to help me solve this problem.

Easy for you to say. Sorry if this offends. Please tell me what I should do in this circumstance. Your most recent response is way over my head. I gave as much information that I could come up with. Other than that, what would you have me do. Should I pretend that I know what you are talking about, or should I acknowledge that this thread has moved beyond my ability to understand. I was hoping to find someone with some recognition of the problems I was dealing with. Obviously not something you have experienced for yourself. I tried everything that was suggested until I got to this last post which made absolutely no sense to me. Of course I can google until the cows come home, and I probably will, trying to figure out what all of the references you made actually mean. I really am sorry if I led anyone to believe that I knew and understood more than I do. I come from the earlier XDA threads for the Nook Color which was a very special place for all of us newcomers who were so excited about learning what we could do. It has been all too obvious that those Nook Color forums were the not the norm. I have managed to work my through a few other android products: the touchpad, the nexus s, and the galaxy 7.7. All rooted with help fro XDA. The 8.9 doesn't seem to have the same interest and dedication that some of the other forums have. Sorry to have been a distraction.
