I accidentally formatted my g-tablet (via clockwork)...and there is no ROM to flash on the root of the tablet itself. I can still boot into recovery but I cannot flash anything since I haven't put a rom on there. Is there a way to flash from the SD card? If not, how can I get something on the tab's internal drive to flash from there? I can't access the tab's internal drive at all from my computer when I do POWER while holding VOL DOWN - I don't have the drivers and I am unable to find them (APX that is, win7 64bit).
I don't have the tablet infront of me, but you can mount your sd to usb mode, and copy a rom to it, all from clockwork. So should should be fine.
You can download the driver here:
developer.download.nvidia.com/tegra/files/android_tegra_froyo_20101105.msi
In clockwork its something like Mounts and Storage. Go there, then mount usb at the bottom.
Now it will pop up on your computer as a removable drive just as if it was booted up. Copy your rom over and unmount, install from SD.

Hello,
Scenario: SGS2, KIES-updated HKI4 firmware (2.3.4), rooted
I have an USB OTG adapter I got from DealExtreme that works quite fine. FAT32-formatted pen drives are instantly recognized and properly mounted.
However, if I plug in a ext2 pendrive, Android says it is blank.
The problem, however, is that the ext2 partition is recognized as /dev/block/sda/sda1, so it is not mounted automatically. If I mount it manually, I can access the ext2 partition and use the pendrive as any FAT32 (with all the added benefits of an ext2 partition).
How can I make Android mount an ext2 pen drive automatically? What config files do I have to change?
thanks.
hii bro ... I have HTC wildfire s with android 2.3.5 ...but its not rooted... what do you think will It recognize fat 32 pendrive if I try to do on the go with it ... or do I need to root my phone ... any suggestion would be much appreciated ...
Most 2.3.x devices with USB OTG support will automatically mount FAT32 partitions without the need of rooting.
Actually, in order to mount other filesystems, one doesn't need root either. All that is needed is access to the console (such as Terminal Emulator) and give the proper commands.
1.hi im abrar i own a sgs2.....i hav bought a USB otg cable but when i try to connect a pendrive to it ......it says ahigh power usb device connected with a triangular symbol..........wat to do........??
2.also im unable to update the firmware of sgs2 via kies everything goes fine but when download finishes on my oc it says Firmware upgrade has stopped working......wat to do plz rply......!
So I skipped the create back up step when installing CM7 (oh boy)then one thing led to another and I'm stuck at the Motorolla Screen. No worries, I go into AndroidRecovery and plug in my phone via USB ready to upload a new ROM only to find that on My Computer I see Removable Disk (E and Removable Disk (G BOTH of which present with a "Please insert a disk into Removable Disk (X." error. I can't do anything! I have no MicroSD Card. From the Mounts and Storage Menu I checked the "mount /internal" but it did nothing and the "mount USB storage" only presented with "E: Unable to write to ums lunfile (No such file or directory)! I've plugged it into three different computers with the same result, all detect the phone but cannot do anything to the internal memory. What are my options? Fastboot?
you can try an adb push or use fastboot to flash a fruitcake
Im having some strange problems connecting my SD card to my SGS3.
Bought a USB OTG cable from ebay 2 weeks ago (this one) and also an SD card reader to plug into it (this one). The phone found the SD card when plugged in and i could browse files from the card fine. a file browser would pop up instantly and allow me to navigate the card. Then it literally stopped working a few days later.
I thought it was the card reader so i plugged a USB mouse into the cable and conntected to my phone and it worked fine, meaning it wasnt the cable. I then plugged the card reader into my PC and it didnt find it, so i thought the card reader might be damaged, and went and bought a new one (this one), but when i plug it into my USB cable, and then into the phone,it still says "USB connector connected" (as shown in this image), but it doesnt launch the file browser, nor can i find the card anywhere in the file system.
Ive turned off USB Debugging from Developer options, but cant for the life of me find out why my SD card cant be read by my phone!
To summarise:
USB OTG cable works fine as ive plugged a mouse into it.
SD Card reader works fine as ive pluuged it into PC with SD card in and i can view files
SD card wont connect to my phone via USB OTG cable
Not all card readers might be compatible, it depends on the chip they use.
I'd recommend using 'real' USB-Sticks instead of SD-cards due to the better compatibility unless required.
The first SD card I bought was working and then suddenly stopped working so I can't understand why this is!
I could probably try a USB stick (will do when I get back from work) but for her purpose I'm using it for, I need to be able to read an SD card.
Really confused as to why this is happening!!
Does USB debugging make a difference being on/off?
so I can't understand why this is!

As I said, probably a different chip in that card reader. It's trial and error.

No, that allows ADB. It has nothing to do with OTG.
"USB connector connected" just means that the OTG cable is connected, nothing else.
In terms of SD cards, especially with readers, they can be a bit of a pain. Better to stick to usb devices. I use a kingston USB card reader and it works with the S3.

Surley if it was working before, then it shows there isnt a problem with any chip's compatability with the S3?

According to your description it was never working.
It worked on another SDcard reader with different internal electronic
If you get the same one you had at the beginning or one with identical chip, it should work again.
Oh i understand what you mean, crossed wires sorry. i thought you were talking about why the first one had sudennly stoped working.
Why do some SD card readers work with USB OTG and some dont? I thought they would all work as all USB?
Card readers are not real mass storage devices but have electronics to convert from SDcard-connectivity to USB.
These need to be controlled by the host computer, and as such need drivers.
Linux and Windows include drivers for most common devices and often can control a device with generic drivers which guess how the device MIGHT react.
If your device is rooted, please open Terminal Emulator (free App on the market) and type: (It may work with non-rooted devices too, I'm not sure)
Code:
dmesg > /sdcard/usb.log
DO NOT PRESS 'ENTER' YET.
Plugin the USB-OTG connector without the device. Wait 1-2 seconds, then plugin the SDcard reader with an SDcard in it.
Wait 1-2 seconds again, then hit ENTER to run the commend.
Then please attach the logfile you will find on the SDcard (with the name usb.log) to your next post.
It should show what exactly goes wrong
Oh i see, I thought any USB card reader would work... i was wrong
Ive done what you said (it did work on my un-rooted GS3), but wouldnt let me attach it, it was saying it is an invalid file, so i put it on Google Drive for you to download. it's here.
The usb.log is for the new card reader that works in the PC but not in the phone. Didnt see any point doing the first card reader that suddenly no longer works in the phone, as it doesnt work in a PC either.
Thanks for all your help so far!
Code:
<5>[64485.553889] c0 scsi 9:0:0:0: Direct-Access USB2.0 CARD-READER 1.01 PQ: 0 ANSI: 2

[...]
<5>[64486.078812] c0 sd 9:0:0:0: [sda] Attached SCSI removable disk
Seems I was wrong and it's recognizing the card-reader all right and seems to be able to access it.
So, for any reason, it seems to be unmountable.
Could you please confirm it's recognizing the partition alright by attaching the card reader to your phone and then typing: (Should work without root too)
Code:
ls /dev/block/sd*
It's supposed to give you 2 lines of output:
sda
sda1
If only sda, please make sure your SD-card is in FAT32 format (not exFat, may cause issues)
If both, go to System->Storage and check if you can manually mount the USB storage (called an SD-card under CM10 at least)
If not, apart from re-formatting the SD-card that's as far as we can go without root, 'mount' commands need root to work.
Yeah it does show both sea and sda1.
I can go to storage settings but I have a microsd card in my phone so when I click unmount it just unmounts the micro sd. When the microsd is unmounted, I cannot mount the SD card either

Hmm, I have no clue why it doesn't automount it.
Should you decice to root (it's a real painless method) we can look further but for now I'm out of ideas on checking the reason.
I've got the exact same problem - my otg usb hub worked with everything yesterday, now it won't mount drives, but my usb keyboard worked? Any help would be greatly appreciated, I only moved from the dark side a couple of weeks ago!

Please try: (with the device attached)
Code:
ls /dev/block/sd*
Remember the last device in the list with the name sdX1 (where x is a letter)
Code:
su
mkdir /mnt/usbdisk
mount -t vfat /dev/block/sdX1 /mnt/usbdisk
(The x in sdX1 here being the one you remembered above)
If it doesn't give an error-message, try accessing that folder through a file browser.

Hello XDA!
I know that there is a USB Mount tool in this rom, and ive tried it, but whenever i press "Turn on USB Storage", it loads for like 30 seconds until the button reappears, not mounting to the computer with either internal or external. I do have adb and fastboot access, and Wndows 7 64 bit sees it as an android phone, just not able to mount files. does anyone know how to mount to computer, because the tool in this rom just doesnt seem to work for me. I do have an sd adapter and can remove the card and have the computer see my sd card that way, but that is more of a pain and wish to have a solution. Dropbox is somewhat a pain too since i only have 2 gb....... Thanks!
