-Yup you got it! They way 7z file work is that it evenly breaks a larger file down into multiple smaller .7z files.

-In this example, the bt.img file is about 486MB. So, 9/10 of the bt.7z files are 50MB each and then the 10th file, holding the remain bytes, is 36MB. So once you have them all downloaded into the same location, you can open ANY one of them and drag its content to the hard drive, and it will extract the entire 486MB, using all of the files. And you only have to do this ONCE, you DON'T have to open each of them and drag all of their content out.

-So yea, now copy the

bt.img

file to the

bt folder

located in the /sdcard/external_sd folder, and then copy the entire

bt folder

to the /sdcard folder instead(Im guessing the ATT version doesn't have an external sd card, cuz the cd /sdcard/bt command is for the /sdcard location and not /sdcard/external_sd, which is where flashing the zip places the

bt folder

). So in the end you're going to use this /sdcard/bt folder and not /sdcard/external_sd/bt...EDITED..and don't quote me on the .7z file sizes from above, not really sure how large they are cuz looking at the file now in my phone its 3.26GB, I was using 50MB for an easy explanation and arguments sake only, thx...and Im actually gonna update OP w/ the step needing to copy the

bt folder

from the /sdcard/external_sd location to /sdcard instead

ok and where's the rest of the info I asked for?
[Samsung Epic 4G Touch] donnyevo4g:
i can only fit so much in the screen shot what else you looking for
[Samsung Epic 4G Touch] KingOfThaJungle:
dude you don't have to take additional screenies, although I appreciate the one already post....just look back a few posts and it says what else I asked for, "help me help you, help me help you" lol there's only so much that I can guess w/o the proper info
[Samsung Epic 4G Touch] donnyevo4g:
iv done everything up until step how to launch bt and when i start going threw the commands everything goes smooth until i get to bt when i type bt thats when i get the chroot error message other than that i been able to download files extract files flash file in recovery and my sdcard/bt folder final directory does look the way you have it in the thread am i answering your question now or am i still missing somthing lol
[Samsung Epic 4G Touch] KingOfThaJungle:
Nope, we're on the same page now man lol....so su, cd /sdcard/bt, sh installbt.sh, and startbt all go through accordingly but then when asked to enter bt to launch, you get that error...hey do me a favor and just check the bt folder and see if you have all five files and if you could, also post up their sizes so I can compare your's to mine(hey now)...especially bt.img, on my phone its 3.3GB..if using MyFiles, going into the app and scroll down to the BT folder, go in, and then long press on bt.img and select details, it should read 3.3GB(3,501,000,000 bytes)
[Samsung Epic 4G Touch] donnyevo4g:
correct when i bt i get the chroot error and here r the sizes as per section

sdcard/bt/bt: size 660 bytes

sdcard/bt/bt.img: size 1.74gb ( i guess thats the problem why is the img smaller then yours)

sdcard/bt/installbt.sh: size 1.02K

sdcard/bt/startbt: size 1.12K

sdcsard/bt/stopbt: size 820 bytes

---------- Post added at 03:20 PM ---------- Previous post was at 03:12 PM ----------

Awesome man, glad you got it running! Will catch up with you after work to hear about the Ubuntu v11.10 project you got going, will be more than happy to help if I can!
[Samsung Epic 4G Touch] Sterist:
so if i hit home to get back to android, terminal emulator would take me back to BT?
[Samsung Epic 4G Touch] donnyevo4g:
if you hit home you will be back in android you can even close terminal and backtrack/ubuntu will still work the only way it shuts down is if you run the commands to shut it down at least thats the case for me i have terminal closed and im still able to disconnect and reconnect no problem at all. hope that answered your question
[Samsung Epic 4G Touch] Sterist:
nope it didn't ;)

how do i get back to BT after hitting home? launch terminal and/or....?
[Samsung Epic 4G Touch] donnyevo4g:
you go back into vnc? or if the connection fails go into terminal and type the following

su

startbt

bt

ui
[Samsung Epic 4G Touch] arvinghost:
i did all these steps:

•su

•cd /sdcard/external_sd\bt

•sh installbt.sh

•startbt

•bt

*and of course i copied the and extracted the file 3.3GB and flashed the update in recovery.

but when i press ui it says

uI: not found

anyone knows what the problem could be
[Samsung Epic 4G Touch] KingOfThaJungle:
yup, it is case sensitive, and I know that whenever an "i" is entered, especially w/ swype, it capitalizes it. Best bet is to install the Hackers Keyboard, free in the Market. FYI it also includes arrows when used in landscape mode, so, lets say you want to enter a previously used command, just hit the up arrow and it'll place the entire string in for you ;)!
[Samsung Epic 4G Touch] arvinghost:
thanks for the reply but i downloaded the hacker's keyboard and retyped the whole thing and still didn't work. this is what i get:

to start GUI (vncserver) type 'ui' (without the quotes)

chroot: can't excute '*/bin/hash': No such file or directory

#ui

ui: not found
[Samsung Epic 4G Touch] KingOfThaJungle:
Did you copy the bt folder to the external sdcard? By default the zip puts it in the other location, being that it was made for the SGSII international, so on ours it places it in the "wrong" location. Us Epic Touch user have to copy it to our other sdcard location, then the commands should work...
[Samsung Epic 4G Touch] arvinghost:
the bt file location on my phone:

/sdcard/external_sd/bt

and when i flashed the zip file i got all the other files inside of it.

is this is the right location or i need to move it to /sdcard/bt ??

I actually would love to see Ubuntu 11.10 with Unity on a 7 inch tablet. At first I hated Unity but after forcing myself to use it for a month, it's great and I hardly every have to use the mouse (trackball in my case). It seems like it would be ideal for a tablet.

i have never been so excited by something that I completely don't need
[Samsung Epic 4G Touch] trizyman:
Only way i got this working

was to use curioct's method located here http://xdaforums.com/showthread.php?t=1162662&page=16. "copy busybox to /data/local/tmp/bt (or create a symlink here) make sure it has read write excute perms (chmod 0755 or root explorer)

copy bt, startbt and stopbt /system/bin make sure they have read write excute perms

You can do all this with root explorer/browser and dont even need the install script

then all you need so do in connect is type three commands

$su

#bt

#startbt

simple if you want to install my scripts which include the path fix and the android file system premounted within Back|track but you don't want this to run from the external sd card simply use a text editor and open the startbt script edit the line that reads :-

export kit=/sdcard/external_sd/bt

to read:-

export kit=/sdcard/bt

if you have the default ones they point to the internal sd card anyway but last I had them they had an export path bug in them which lead to problems inside back|track

if you want my advice given the simplicity of these tasks, if you use my scripts I would highly recommend putting a # in front of the three lines that begin:- $bboxpath mount --bind this will comment them out (prevent them from running in the script)

This will for the time being stop back|track mounting your android internal / external and USB drives thus preventing you acidentally screwing them up from within back|track

given that this stuff is basic linux command line you might want to consider learning more of it before playing with back|track, just a thought." Hope this helps others..

Can Ubuntu 11.10 on E4GT run Google Chrome? This would be a killer option as you could log into Chrome and share favorites and open tabs between your computer and phone. Just a thought. All that while running GB... that would be cool.

[Motorola Atrix 2] Clovett:
I'm updating the puny 2Gb placeholder in my Atrix 2. I finally settled on a little known name , Dane Elec, and ordered it from New Egg. Cost me $55 shipped and it's a class 10 card. They are the company making the new Duracell flash units. When I get it installed I'll come back and do a review if anyone is interested
[Motorola Atrix 2] spd_rcr:
subscribed :)

Looking forward to your follow up.

I just ordered up a 32 gig class 10 as well. I was digging through all the data that seems to be split between the onboard and the sdhc card. I'm curious what happens with the various apps when you replace the card.
[Motorola Atrix 2] cushcalc:
Moving data over to new bigger SD card

I'm pretty sure that if you mount both SD cards to your computer and copy everything from old to new, that the system has no problem carrying on with new card with more space. I have done this several times with Inspire 4G, did it once with Atrix 2 going from the stock 8 to a 16GB that I had, and will be doing it again soon with new 32GB.
[Motorola Atrix 2] Clovett:
So do I need to put the new card in and let the phone format it first or format it on the PC?
[Motorola Atrix 2] cheetablaze:
Let the phone format it, and then transfer the information to it. Good luck with the class 10 micro sd cards. People on the forum to include I are having issues with them. Supposedly going down to a class 4 and 6 will remove the problems the phone is having.

Taking pictures or recording video, the items will show up at as non readable. Everytime I take a pic the first pic is always bad, all of the others show up just fine. Gets annoying but i've managed to overcome it. Also when that happens all of the pictures you took after take a year to show up in the picture viewer. I have to reboot the device just to take a look at the ones I just shot.
[Motorola Atrix 2] Gadgetz:
Having a class 10 card in my phone, I concur. I have yet to get a class 4 or 6 card to replace it yet but I have heard that doing so will remedy the r/o issues the phone has. Gonna stop by Frys today and pick one up, maybe even a 16gb.
[Motorola Atrix 2] mtnlion:
I'm running a 16gb class 4 and haven't had any issues so far.

well crap, unfortunately i'm not made out of money. going to roll with the busted class 10 for awhile until I can figure out something to do. I wonder if best buy will take it back if all i give to them is the micro sd card and a receipt... haha
[Motorola Atrix 2] Gadgetz:
I picked one up today, 16gb class 4 by Kingston. We'll see how it goes.
[Motorola Atrix 2] kindacrazyazn:
Some here, smooth sailings so far, but i don't have much on my sd card right now.
[Motorola Atrix 2] spd_rcr:
shoot, I already placed an order for a class 10, I just assumed it was higher quality, like the way cpu's are binned for speed.

Any recommendation on a specific card that works w/o trouble ?
[Motorola Atrix 2] JRW 28:
I've been using a 16G sandisk class 6 card without any problems, glad I seen this thread because I was just about to order some class 10 cards. Guess I'll b holding off on that now.

i am using a sandisk 16 gb class 4 card that was really cheap on newegg with free shipping. i am not sure if the deal is still going on. there is a link below:

http://www.newegg.com/Product/Product.aspx?Item=N82E16820171486
[Motorola Atrix 2] Mytwuk:
I copied what I posted in another thread.

My experience has been just the opposite. I originally purchased a 16gb class 4 PNY card and I had the aforementioned read only issues. I then exchanged it for a 16gb class 10 PNY and all has been good since. and that has been about 3 weeks ago. Go figure?

New Question:

Could it be that different manufactures arrive at various class standards using different architecture? Maybe the same class of card from one manufacturer can act differently then another manufacturer? I think ultimately that it shouldn't matter which card we use if the software/hardware is correct, we should be able to put any "reasonable" card we like in the phone and it should work. Hopefully Moto will issue an update so the phones wont be so picky. By the way I love my Atrix 2 and have no desire to get anything else.
[Motorola Atrix 2] Gadgetz:
Its not that simple. It depends on the hardware.....my HD camcorder for example, it specifically states that it needs at least a class 4 card, otherwise the info cant be written to the card as fast as it needs to be and will error out. Im sure something similar is at play here. But with Motorola not specifying what class card its compatible with it becomes a trial by error. So far the most common thing among the many people who have had this problem is the class 10 card.
[Motorola Atrix 2] Mytwuk:
Yes I agree I have been playing with HD camcorders for a few years and I understand that the medium whether it is a card or a disc or tape needs to be able to keep up with data stream being sent to it. Im sure something similar is at play here as well but a faster card shouldn't give negative results? You are right that a camcorder has a "minimum" rating but although a faster card will not necessarily give any better performance it certainly shouldn't be worse or cause issues like it appears to on these phones.
[Motorola Atrix 2] Gadgetz:
Logical, but its not always like that. Example....in car audio, the head unit sends signal via rca's to an external amplifier, the higher voltage the signal, the more efficient the amp will be and the better it will sound. So logic will tell you if you can get an 8v signal to the amp then it should sound lovely since most signals are 1-2volts....well, if ur amp can only handle up to 6v signal then feeding it an 8v signal will cause the amp to go into protect mode and not work right.

HP USB Disk Storage Format Tool 2.1.8.0 recommended

I use HP USB Disk Storage Format Tool 2.1.8.0, based on recommendations on other xdadevelopers forums such as Inspire 4G. Supposedly does a more thorough format than the stock Windows 7 utility (certainly takes longer). Using this, I have had zero problem using Class 6 and Class 10 cards.
[Motorola Atrix 2] cheetablaze:
I think I shall try this now

I had my hopes up for this to work... but sadly it does not. Using a PNY 16 gb class 10 card.
[Motorola Atrix 2] Clovett:
It's a bust on the Dane Elec class 10 card. It doesn't say what class it is at New Egg but has a prominent 10 in a circle. Turns out that is for the warranty. It's a class 2 card, goes back today. After reading all this I may step down to a class 4 or 6.

NewEgg has a class 4 32gb card for $41 shipped ordered that based on what I've read
[Motorola Atrix 2] Gadgetz:
Lmao.....better hurry and snatch up the SanDisk 16gb class 4 card they have on sale for $17.99 free shipping before they sell out!

Change it out, u know that dead pixel is gonna bug the crap out of you. Just stick with a class 4 or 6 card and u should be fine. I havent had the sdcard issue since swapping out my class 10 for a class 4 on monday.

Transcend 16GB class 6

Hi,

I just got the Transcend 16GB class 6 microSD card yesterday from Amazon. It came in the hassle free packaging(meaning not the original packaging). I had no problems installing it. I copied the contents of the 2GB to the pc, unmounted and removed it. Installed the new one, formatted then copied the contents over. Everything seems fine except I could not see the Album art for the mp3 files downloaded from Amazon. So I reformatted the card and manually downloaded the mp3s. Now everythings great. Although other than photos and videos I did not copy over anything else. So I expect some problems with apps whose data was on the SD card. But just re-downloading the app should fix that..

Just ran the SD card test using SD Card Tester and Antutu Benchmark...definitely the SD Card Tester seems to be more reliable

I got an ADATA 32GB Class 10 that works perfectly in the Atrix2. Its been previously in the Galaxy S2, Galaxy Skyrocket, and Galaxy Note and I never had problems. As long as you have a high quality card with good reviews from reputable sellers than you should be ok, avoid the cheap junk and stay away from ebay sellers, I purchased a generic card once from ebay and it was nothing but problems. I usually stick to Amazon and Newegg even if I pay a little more just because I trust the products they ship aren't generic knockoffs.

EDIT: After much use, my ADATA 32GB Class 10 started to have issues too. Motorola needs to come out with a fix. I put in a temporary ADATA 8GB Class 6 and its working properly.

Comment/question on sd card issues and Media Link

I have had an Atrix 2 for two weeks. After purchase I quickly picked up a Verbatim 16gb Class 4 card and commenced having problems with pictures often not saving. (I don't know the class of the 2gb card that came with the camera, but so far it has no problems.)

After reformatting the 16gb card using Windows format (not quick format) yesterday, it worked well in limited testing - all pictures seemed to save.

I then used Motorola Media Link to sync some music from my iTunes folder. After that, again in limited testing, the camera seemed to have problems saving.

I'm not saying it's the Media Link software causing the problem until I test further, but could any of you report on your use of this software?

Thanks.
