A couple of questions....MyTouch 3g

I came from WinMo phone which I used to flash all the time with different ROMS. Now I have this Android and am not sure what to do with it, I love the phone, have had it for about 3 months now, but I know it can do bigger and better things. So is rooting the same thing as unlocking? When I used to flash my WinMo phone I would drop the ROM into the little software flash package I kept on my hard drive and change it out. Is there such a thing for Android. I really like this phone and don't want to screw it up assuming I know what I'm doing because I did it on my other phone, I want to edumacate myself like I did before I started flashing my other. Does anyone have reliable good information links they can point me to within this forum that will help me feel good about flashing this phone too? I know I've read that just rooting the phone makes it run faster without flashing a ROM....true? Thanks for your help, suggestions, etc. All is appreciated.

Wow... Amazing that you could put in the effort required to post all of this, but couldn't read through the Wiki posts and general information stickies at the top of this Forum.
Please do some more reading.
One hint... Your MyTouch 3G is a 32B device.

I was really confused when I started customizing my girls mytouch...Ive been flashing WM phones for years even update my kitchen with newest releases etc. In fact I personally use a touch pro.
I have yet to really sit down and figure out how to make some android roms myself. Ive been loading up premade roms posted on here.
It was a bit confusing when finding out how to get a hero rom on her phone. With all the fat 32/ext2/3/4/linux swap etc.
What I did was followed the one click rooting thing that loads cyanogens recovery and rom. Then I took the amon_ra recovery which allows you to partition the sd card on the device since I didnt have an sd card reader on my laptop or linux. When you are loading the cyanogen recovery/rom you'll download an app from market called recovery flasher or something like that. In the first step you'll be asked to backup the cyanogen recovery which makes a file on the sd card. Take the amon_ra recovery file and rename it the same as the backup file on the sd card. Overwrite the file on the sd card. Rerun the recovery flasher app and click restore from backup..Follow the instructions and you'll have the Amon_ra recovery.
Boot into the recovery screen (hold home and power until it boots up) partition the sd card. I have my girls 1gb set at 256mb ext4 partition, 64mb linux swap, and the rest as Fat32.
Then load up a rom make sure its intended for 32b.
I by no means am an expert in this so take what I said with a grain of salt. I wrote that from memory. Just trying to help someone out the was just like me a month ago. Really confused.
Hope that helps.
PS. Took me a while to find out but despite this being the forum that seems would be for the mytouch I actually find more roms for 32b in the G1 forum.

You can check out the wiki page on cyanogen's website:
http://wiki.cyanogenmod.com/index.php/Main_Page
that was enough information for me to get started. Note that I haven't partitioned my sd card.

maybe u can try this tutorial .. it's one of the simplest direct methods to flash ur phone
http://forum.xda-developers.com/showthread.php?t=579328
p.s. : expect things to be more complex here it's just linux way of doing things

I used the guide at the cyanogen wiki and it works marvelously. I do reccomend using Amon_RA's recovery image instead of the Cyanogen one used in the guide(not to be confused with Cyanogen's ROM. Absolutely use the ROM, but when you get to the Recovery Image part, install Amon_RA's and follow the same steps, making sure to adjust command lines to reflect this different recovery image).
It just offers more functionality that I'm sure you'll find useful for later, such as backing up, partitioning, converting ext partitions and so forth. You'll learn about that stuff later.
Happy rooting, and best of luck to you my friend. As a fellow myTouch3G user, feel free to PM me with any questions. =)

Possible to boot Ubuntu from Sd card?

Hi,
I know there's already a thread about Ubuntu, but I ran across this, and it looks a little different:
http://forum.xda-developers.com/showthread.php?p=10306407#post10306407
It looks like, instead of replacing the Nook Color ROM, they're booting Ubuntu from the (external, I think) sdcard.
Would it be possible to do something like this with the Gtab? If it is, maybe we could have an Android/Ubuntu dual boot?

The above is the based info on this. It looks like, basically, they run Ubuntu under chroot (in a jail).
This seems like it'd be cool, on a Gtab!

Would it be fast like that? I used to run Android on an sd card on my old HTC Titan phone. It was slower than Molasses in winter.. Would be neat if it could be done, and was still fast.

Hi,
I don't know the answer to your question, but we run stuff under chroot all the time (mainly things like Apache httpd) for security reasons, and running under chroot doesn't add overhead. It's not like it's running a VM/hypervisor. Rather, chroot just isolates the app (in this case, Ubuntu) from "seeing" the rest of the system, so I think that if it could be done, the Ubuntu "instance" would run at native speed. Again, this would be more like a dual-boot configuration, rather than a VM type situation.
If you read through the 2nd link, it's kind of neat the way they did this, i.e., they got just a command line Ubuntu going first, then they used apt-get to bring in the X stuff on top of that, kind of like bootstrapping, at a little higher level. Also, similar to how the earlier versions of Windows worked, i.e., basically you'd boot to DOS (yikes !) then start Windows from there.

i want this soooooo bad.....

When I have some time, I wouldn't mind trying to get something like this working on Gtab, but at this point, I'd (we'd) need some guidance.
For example, would we need our own img file for the Gtab, or could we use the one that was linked on those sites? Those are, I guess, for Nexus One and for EVO, so the native code would be for Snapdragon. Would those work on the Gtab, which is Tegra 2?
I originally hesitated posting this in the Development forum, but maybe it should be. I don't know ...

There is an ubuntu image that runs on the external micro-sd card. You have to change the boot loader to run it. Right now you have to have an external mouse and keyboard.
http://forum.xda-developers.com/showthread.php?t=894960
It does not modify the internal storage so you can restore a boot image from Clockwork and boot back into android.

Hi,
I read through some of that thread for awhile now (not too closely), but I had the impression that the Ubuntu in that thread replaced the normal Gtab ROM?
So, is the only thing that gets replaced on /sdcard the boot image? If that's the case, then it wouldn't allow a dual boot, without using CW and restoring the appropriate boot image?
Sorry, not arguing, but just trying to understand...
Jim

It uses a custom boot image to load ubuntu from the micro sd card. It will not boot android. You have to reflash the boot image to boot back into android. There is a post in that thread (#57) where a dual boot capable boot image is being asked for.

I think I remember that "request" in that thread ...
I guess that the nice thing about the approach at the beginning of this thread, if it could be possible, would be both runnable "images" (the Gtab/Android and the Ubuntu) would exist (but not run) simultaneously, the former on the internal SDCARD, and the latter on the external microSD card...

ext2 support?
Hi,
I've been reviewing the shell scripts that are used for this (downloaded from the link from the original NC thread), and it looks like almost everything would be ok, except:
- It looks like the ubuntu.img file is an image with an ext2 fs on it (they do a loop mount on it). I tried "busybox modprobe ext2" on my Gtab (stock TNT 3452), and it looks like it doesn't have the .so or whatever to support ext2. Does anyone know if it's possible to get ext2 support on the Gtab?
- I was hoping to at least try the mount, to see what's there, but since I can't, I'm still assuming that the ubuntu.img was compiled for the NC, so I'm still wondering if I could get it mounted, if the code in there would work? According to:
http://www.engadget.com/2010/10/28/nook-color-processor-revealed-arm-cortex-a8-based-ti-omap3621/
it's an "ARM Cortex A8", whereas the Gtab uses a Tegra 2, which I guess is an ARMV7?
Thanks,
Jim

Change boot device priority

Hi! I'm looking for a way to modify boot mechanism on my xoom to make it able to pick up any boot setup from SD automatically.
Currently I'm able to boot into linux console of debian installed on SD cart, but for that I must always keep a initrd snapshot in boot.img and as you understand this is not the best way of playing around with setup.
In the end I want to make it able to boot from LiveCD image made on SD card or USB drive just like you boot up from Live CD on a PC platform.
I understand that there's no such solution, so I'm looking for advices and nice articles that could help me in that.
One important thing: I don't want to keep a mini linux kernel in boot.img and then chroot to other environment, system must be as much independent as possible (in case, let's say I'll try to boot... in Windows XPE or such)

Looks like you've done some interesting things with your xoom, maybe you could post some details of what you've done so far and how you accomplished it so others could have a mess including me.

Try taking a look at the nook color development pages. The nook by default boots from SD, and they also have a dual boot option developed.

I wanna dual boot Ubuntu / Android on my SL 101

Ok, so, I want to dual boot ubuntu and android but:
I do not want to change my current partition layout (and lose all my data)
I don't want to touch the current android install AT ALL
I would like to run ubuntu from my SD Card
I would like to run ubuntu from an Image (img file) on my sd card
I would like to press vol down and power at boot to boot to ubuntu
I am rooted, I have (what the sbkcheck says) SBKv1
One more thing.
Why don't we have an SL101 forum?

I believe there is a pseudo-dual boot for our device where you could run Ubuntu from SD card. But if I remember correctly, each time you want to switch operating systems, you have to flash a different kernel. I'm not entirely sure though, I'll keep looking for the post.
Even though you have SBK1, SBK differs per device. Meaning Nvflash still isn't available to us yet.
Also, SL101 doesn't have a forum because frankly there aren't enough users. Plus the device is so similar to the TF101 and some ROMs run fine on both.

I remember seeing a way to flash the recovery partition with something that allowed you to press vol down and power to boot to ubuntu, using the SDcard as / .. basically i'd like that type of setup only with an .img file on the sdcard instead of using the raw sdcard.

[Q] where is boot options on transformer infinity?

I unlocked my boot loader and have not yet found where I can boot from a SD card or usb thumb drive...
I want this as a step towards partitioning and dual boot option...
I have the 64gig infinity, I want to install 10.4 Ubuntu, or more modern mint, or...
Any words of help, how to get this infinity to stop and notice my usb thumb as a boot option?
THANKS
koko

Unlocking the bootloader only allows you to install and boot unsigned recoveries and kernels. Little is known how to reconfigure the bootloader - I have never seen a thread here how to do it. However I know some of the theory behind it:
Tegra devices use a proprietary partition table. On some devices, like our TF700, this partition table is even encrypted with a device-specific key, same as the bootloader itself. This is the partition table with the 3-letter partition names like BCT, PT, SOS, LNX, etc. It is used for the bootloader's blob flashing feature, and for NVFlash.
The Linux kernel on the TF700 (also on the TF101) uses a standard GPT, which is located at the end of the eMMC. This partition table does not contain some of the hidden partitions, in particular the boot partitions that contain recovery and kernel are invisible.
I think your safest bet is to use the same kernel for both Android and your Linux distribution, like rabits did, or try to use kexec.

Thanks for responding! I appreciate it =)
And I wish I knew enough to try what you suggest, but I do not...
I got this infinity for 2 reasons, one was the hardware looked great to turn it into a linux box, the other was to use the speech to text function...
I was told by the sales guy that function worked fine out of wifi range... I guess he must have had a cell version od android, as I get nothing out of wifi range. Now I wish I had never gotten this, or at least never unlocked it with the asus unlocker so I could return it!
oh well, live and learn, I guess someone will still give me SOMETHING for it.
Unless someone else here tells me how to run non-android version of linux on this box ? Please ?!?

Read the Ubuntu thread from rabits.
