I am trying to Flash my G Tablet with a new ROM. When I view the existing files on my G Tablet using the resident file explorer two SD cards show up, SD and SD2 but there is no SD card installed in the slot. The reason this relates to my attempt at flashing the ROM is the mystery SD card is the only thing my laptop shows when tethered using the USB cord.
Can I delete these mystery SD cards without any harm?
If I do delete them, will my laptop then be able to get to the Root folder so I can transfer the Clockwork Mod and TnT Lite files?
Hmmmm interesting i have never heard of that problem (not that its abnormal).Well in the viewsonic g tablet there is an internal sdcard, but you mention a SD card 2. I would reccomend NVFlashing because this may just be a glitch and it will restore your tablet back to normal. And as a plus, it will be very helpful learning how to NVflash your device because it comes in handy very often. Hope it works
Noob here. Device is 16GB NT, rooted 1.4.1, using Albert's SD card. Works like a charm, but various apps show that they are not compatible with the NT. I would like to try the external CM7, and flash it to internal after I try it out.
I have tried several SD cards, (8GB Sandisk Class 4, 32GB Sandisk Class 4, 8GB Transcend Class 4) and two ways of imaging the CM7 file (using Winimager32 with the SD in an SD/MMC reader/writer on my laptop, using Winimager32 with the SD card in the NT). After imaging the SD, I have attempted to boot without expanding Partition 4, also with expanding Partition 4 using Gparted, and expanding Partition 4 using EASEUS Partition Master and Mini-tool Partition Wizard. I have gone back to a clean SD by using Windows to reformat the card, and by using the NT to erase and reformat.
I think that I must be missing a simple step in the process, but after searching XDA, Tabletroms, and Google, I am unable to come up with a solution.
Questions that I have are:
- Is it necessary to clear the dalvik cache when using the SD card? (I don't think so, since all boot and setup activity seems like it does not include the internal boot/system files)
- I came across a thread that says that a "cache" folder should be added to the root of the "data" partition. Is this a required step?
- Do the second and third partitions require the "system" and "data" labels?
- I set the attributes of Partition 1 to Active (LBA). Do I also need to set a boot attribute?
I apologize for the long-winded post, but I appreciate any pointers that you can provide. BTW, the efforts of all those who have taken the lead to improve the NT are first class, and the help provided by members of the XDA community here are impressive, to say the least.

If you mean you're not able to boot up at all, try plugging your NT in then turn it on. Some people's NTs will only boot when attached to the cable.
Re: Android Won't Skate
Thanks for the quick response. I left out a few items in the original post.
I have to tether my NT to the plugged-in charger to get it to boot with the SD card installed. I get the Team B splash screen for about 15 seconds, then it goes to a black, backlit screen. I have waited as long as 20 minutes, but nothing happens. I have also popped out the SD card, and reinserted it, as have others in this forum, but to no avail. When I power on untethered, I just go to the normal NT boot.
If I boot up normally, insert the card and use ES File Explorer, I can see four folders, plus the boot.img, flashing_boot.img, MLO, and u-boot.bin. Also, when I use GParted, I can see the four partitions, and when I use ext2explore, I can see many files in both of the Linux partitions.
Hope this adds a little more clarity to the original post.
Thx.
You shouldn't have to make any changes to the SD card after you write the image to it. Just put the card in and power on.
it 'sounds' like its your sd card. did you try it with just the one ? imho, because the card is choking... go get a 4 gb class 2 and try again.
1) sdformatter, fat32, not quick...
2) then use 'Win32DiskImager.exe' . . .
Android now skates
I finally got CM7 to run from the SD card(Sandisk 32GB Class 4). Used another PC to image the SD card. Worked on the first attempt.
Hope this helps others who have had this problem.
the main thing that those of us who came from nook colors will know is dont use laptop sd card readers.. prolly half the posts i seen were due to using one of them. the best SD card readers are the PC ones and using a proper image writer.
as far as the app issue.. if its like the nook color you can always edit your build.prop to make it show as another device on google play
I seem to be having somewhat of the same problem.
I got an 8 GB (4) and burned the CM7 image to it using win32diskmanager, then used easeus to partition my drive. Put it in my nook, perfect, everything works.
A few days later I got my 32GB (4) card in the mail and did the same thing. Put it in my nook, and it wouldn't boot. I can see the TEAM B+ splash screen but nothing else, screen turns black afterwards and nook reboots to nook stock.
I don't know why it does this, could be sd card problem.
Im I missing something? do I have to do anything special if im using another sd card on the same nook?

If it worked perfect the first time, it has to be an SD problem or a burning problem. I'd try rewriting the image to that SD card.

So I reformatted the 32GB card using SDformatter (lost 2GB in the process) and burned the image one more time.
Same thing happened. Nook keeps booting back into stock (after team b's splash screen). I re-insert my 8GB SD card and it works perfectly.
Must be the SD card unless someone knows what else is happening... I guess thats what you get when you shop for SD cards on ebay.

You might want to try booting up with the power cable in. Some of these SD cards and NTs just like to be difficult, but it's worth a shot anyway.

Very peculiar things are happening.
I had put my 32GB SD card away until I read your last post, thinking I might try to reboot from card with he power cord like you suggested to see what happens. So I put my card in and it loads to stock nook. No CM7 splash screen like before. I reset the device and tried again, nothing.
I think the card might be bricked now. I checked to see why this was happening and now my devices won't see the SD card. The nook asks me if I want to reformat the card, but it crashes if I choose to do so, and windows won't see the drive the card is on so i'm not able to format or play or see the partitions.
Edit: Wow. Ignore that. As soon as I posted this my device finally reformatted the card. Will try again now.

As long as the SD card mounts, you should be able to get your card back to normal by deleting all the partitions then creating just one, formatted as FAT32.

Re-burned the image. Nook will not start at all now with the card in there. I played with the power cord and left it there for 2 minutes and it powered up, however, no splash screen or anything, boots to stock NT.
I turn the NT back off, same thing, won't power ON. I wait two minutes with power cord on and it powers on then.
Bad SD card?
Card has:
.android_secure
Android
B&N Downloads
LOST.DIR
My files
boot (img)
flashing_boot (img)
MLO
u-boot.bin
When I had issues, I followed old fart's suggestion and reformatted my card with sdformatter first. then burned the image with Win32diskimager, both on another PC. When finished, I ended up with a 3.8GB image on the SD card. Nothing worked until I used the other machine. After I was sure that the card was going to work, I expanded the fourth partition to use the rest of the space on the card.
BTW, I had to use the USB cord, plugged into the charger to boot up. Worked on first try. Been happy ever since.

okay, you got me really curious. . . . what's the 'other' machine and what did it do right that the first attempt / machine did wrong. hmm ?

What do you mean by nothing worked until you used the 'other' machine?
Sorry for the confusion.
I made many unsuccessful attempts to make the sd card on a Sony laptop, using an sd card reader in one of its USB ports. It wasn't until I switched over to the "other" machine which is an old Compaq desktop, that I was able to get a good image on the sd card. The point is that I had to switch to different computer to create a good image. It seems like something on my laptop prevented me from making a workable image on the sdcard. Hope this helps.

It could be the read/write speeds. What I do is I use the nook as my card reader, since I dont have a card reader on my PC. However, I do have one of those USB card readers. The difference between them is that when using the nook, it writes at about 3-4mb/s while the usb card reader writes at about .5-1mb/s.
I'm having problem booting my nook from sd card, I have tried flash CWM ver. 3.2.0.1 with win32diskimage to my 16 gb microsd card. Then copy manualnooter-5.02.19.zip into sd card. I can see the files in my window7(mlo, u-boot, uimage, uramdis and manualnooter files). Put my sd card into my nook slot, power it on. It just gave me original nook screen. I followed XDA developer method a few times, nothing just gave me nook screen. With my nook I also can see all the files
I have tried several methods, used 2 gb sd card, reformatted the sd card with window7 utility (fat32), formatted with nook utility.
Is there a model from nook can't boot from sd card?
My device model #BNTV250A, software ver. 1.4.2
Please help
The Nook needs external power to boot many SD cards. Just turn your Nook off, then plug the USB power cable into the Nook and wait. It should then boot from the SD card.
I tried that, still boot to nook screen
Try a different card.
Try using the instructions and imaging file from this post "How to root 1.4.1 (or any other version) using just an sdcard {easy}" from Indirect. Sorry I can't link yet..... It is an easy to use method. Also, try playing around with different SD cards. I had to dig around and pull cards out of every camera and mp3 player to find one that would work. Not all of them do. I found a 4Gb Class 4 card that will boot every time.
Do you have an 8GB nook tablet? If so this worked for me:

Hey guys, I used ALberts method for rooting using the micro SD card and now im kinda sad. Im sad because I deleted everything off of my 32gb micro SD card and now it's only showing that it has 76MB on it. I reformatted and it still is only showing 76mb. Anyone know how I can have mah SD card back lol?

I had the same frustration and figured there was some magic I didn't understand re: image files. I "believe" that the image you select with the windows disk imager (Win32DiskImager.exe), which I believe is named cwm_sd_flashing_boot.img controls how much free space is left. In other words, that image is only around 70 MB or so, and when you transfer the image to the USB, that's all you get.
I was using a 2G SD, so no big loss, but when I went to place the .zip file for CM9, there wasn't enough free space available. What I did was copied the CM9 zip and gapps zip to yet another SD, booted up with the original 70 MB SD and then popped in the larger SD when asked to select the zip to flash in CWM. It worked.
Since then, I realized that all you have to do is format your larger SD as a bootable FAT32 drive, ie, set the boot and lda flags, then copy "all" the files that were in the original SD drive. After trying to puzzle it out for two days, I got it working tonight.
For me, I just formatted a 16 GB SD as bootable and then added all the zip files I'd need, and will use that SD in the future for CM9 and other upgrades.
As far as how to make a bootable drive, I use linux (and dual boot windows 7) and used the gparted program as recommended by indirect. It allows you to set the boot and lda flags which I guess is all you need to make the drive bootable. I have no idea how to get windows to do that without some other app. You can always create a gparted live CD and boot into it.
Good luck.
PS The files I found I needed on the SD to make it boot are
boot.img
flashing_boot.img
MLO
u-boot.bin
...as well as Gapps_and_root.zip and any other zips you want to load.
I'm not sure of MLO and u-boot.bin, but I put them in and it works.
PPS I also found that if you leave the USB connected to your computer, it will boot right into the SD. If not, you probably have to do the power and N buttons at the same time thing.
Recovering SD Capacity
I had the same problem, but then I read somewhere that if you just use the NT clear SDCARD / dismount while the MicroSD is still in the NT (of course), it will revert back to it's original capacity.
Worked for me...I can look through the menus and get step by step instructions if you can't follow the crappy way I described it above.
Lol, thanks for the advice guys! I'll try it, hopefully Im not screwed
Dear XDA'ers.
I've had an S2 for a while now and I've been running CM9 since early alpha. Recently I decided to buy an SD card (http://www.amazon.co.uk/gp/product/B005FY61EK/ref=oh_details_o01_s00_i00) so that I can use it to store my movies. After I got it, I realised that MoboPlayer or AirDroid couldn't detect the SD card and the only way I could put something on it was through a physical USB cable. Now, today I wanted to try something but I found out that my phone doesn't show the SD card at all anymore. I tried taking it out and putting it back in several times as well as flashing the latest CM9 nightly but nothing happened. The only apparent difference that I can see when I put the SD card in is that in the Storage section in Settings, under the SD card tab, I have an option "Mount SD Card" but when I press it, it says preparing SD card yet nothing happens.
Is the SD card fried or what's wrong with it?
I've had the SD card for less than a week so its hard to believe that it's dead already.
Have you got a micro SD card reader that you could use to see if the card is fried? Connect it to your computer, and if it shows up it isn't fried. Also check the format of the card to make sure it is in FAT32 format.

Ahh, I know the problem now (I completely forgot about this).
I formated it to NTFS just before I stopped working since I assumed that it works the same way a USB does (but clearly, I was wrong).
I'll format it back and see what's what.
Have u tried going into settings/memory/left softkey/storage config and select the only options there is?
have you tried other system folders?
i had the same problem before, I found out my sd card mounted as a system folder called "emmc" I'm using resurrection remix rom 2.3
Yep just fixed mine today by downloading https://play.google.com/store/apps/details?id=pl.qbanin.binder&hl=en if you are unsure of what to select just see the screenshots i followed this selections and it now works fine
Alright, I've fixed it.
Basically, I had formatted it to NTFS because otherwise it gave me some error about file (the file was around 4 gb's and it acted this way with anything over 3) being too big when I was trying to copy it onto the SD card. Now that someone said it has to be in FAT32, I formatted it back and now it works perfectly.
Thanks to everyone who helped me.
