[Q] Can't mount SD Card in TWRP

I recently rooted my kindle fire and installed twrp along with cm7, but I accidently did a factory reset inside cm7 and was stuck on the firefirefire logo, I used an unbrick tool, but that erased all my user data and did not help. I managed to get my boot back to 4000 and install twrp again, but it won't let me mount sd card and will only allow me to mount system.
Sorry Im a noob

Im having the same issue, trying to moun it, but I keep getting
Error mounting /sdcard!
Is there a way to fix it? Im stuck on recovery (CW)

Heres a great idea get off of the discontinued recovery and switch to touch screen clockworkmod recovery its way better when it comes to things like that

guys this has nothing to do with twrp - it's working fine
just do following:
- boot to twrp
- test adb with "adb devices"
- open shell -> "adb shell"
- issue "echo /dev/block/mmcblk0p12 > /sys/devices/platform/usb_mass_storage/lun0/file"
- now the sdcard should mount to the computer
- windows will probably respond that the volume/device needs formatted before using it
- choose quick format and let it format it as fat32 block size 4096

Thanks b63 for the fast reply. I dont have twrp I have CWM recovery, im trying to install TWRP but I get an error:
error: device not found
Is there another way to install TWRP?
Thanks

i don't know about cwm but i would try to boot to it and test if adb is working
then it should be the same - you only need adb root access
if you have this access with cwm also then there is no need to install twrp

Well if I boot into CWM
I can do adb shell
But then nothing happens
If I let Kindle boot normally (after the Yellow triangle) the screen goes black and I cant adb shell anymore
What im doing wrong or what im missing.
Thanks again
BTW
When I boot int CWM I get this message
E:Can't Mount /cache/recovery/command

stay in your recovery
after the command the sdcard should mount to your computer
check your device manger
follow the first desciption
if you can't get it gimme a pm ...

Wooooot!
Thank you so much b63!!!!I couldnt sleep for this damn problem
In the end this one help me out
echo /dev/block/mmcblk0p12 >> /sys/devices/platform/usb_mass_storage/lun0/file
I dont know why it worked with >> its the same (for this case) but I could finally mount it on windows
Now im back to CM7, really thanks!!!!!

really glad that it worked ...

b63 needs a medal lol.

Thanks b63 I got twrp to mount the sd card, with this:
echo /dev/block/mmcblk0p12 >> /sys/devices/platform/usb_mass_storage/lun0/file
But, when trying to install cm7 I get an error:
E:Cannot load volume /misc!

ignore it - the kf don't have a volume "misc"

Stuck in twrp!!!!

I can get into TWRP, but when I type in ADB DEVICES in command prompt, it says the standard daemon not running, then daemon started successfully. This is followed by List of Devices attached, but it's blank after that.
I used the Kindle Fire Utility to install drivers, and when I use ADB DEVICES Command Prompt with my T-Mo Vibrant, I can get into ADB Shell.
Any advice?
Please note, this isn't mine. I've never owned a Kindle Fire, so I'm banging myself raw with information overload on this type of device. I'm trying to help a co-worker out with his Fire that he borked. I've owned three android phones/tablets and rooted/ROMed all of them, so I follow instructions. So far, I've tried the Kindle Fire Utility and the Kindle Fire Unbrick Utility found in these forums. My co-worker didn't get to the point of making a back-up or installing the Stock Image as an Update.zip. I have the stock image downloaded, and have renamed it, but I can't get it onto the tablet at all. Selecting Mount in TWRP always locks everything up, and there is nothing to Install or Restore. So, like I said, I'm getting bloody here, but no joy.
Any help would be appreciated!

what's the status of the kf ? -> you can get into twrp - that is good - do that
what's the status of the drivers in device manager ? -> which driver loaded ?
what have you/he done/tried to get to this point?
i'm asking to give you the right method ...

He says he rooted it, installed FireFireFire, and the ICS-ish launcher (name eludes me at this point). Then, it basically boot-looped (Yellow Triangle, then Kindle Fire, back to Yellow Triangle).
My first thought was ADB Shell, but the KF is apparently a stranger animal than most of the other Androids I've dealt with, so it didn't automatically pop up. I installed KFU (Kindle Fire Utility, most recent version), installed the windows drivers (I have Win7 Pro 64-bit) that came with the KFU, and attempted to get it to boot normally, recovery, or anything. Note - A couple of times (like 4 or 5 out of 100), it did make it to a full boot for a few seconds, but would crash within seconds. TWRP was not installed at that point, so I successfully pushed that with the KFU. I also downloaded the stock image, and renamed it. TWRP won't mount the SD card so that my computer can see it, so I'm losing that battle. Also, at some point along the way, the KF started attempting to connect to the PC when plugged in, with the typical USB device connected sound, but two seconds later, it acts like it is unplugged, with that sound. If the KF is visible in the Device Manager, it must be hidden, cuz I can't see it. This was not the case at first, with an Unmount icon for the Kindle being displayed in the notification (right) side of the Windows toolbar. This is in conjunction with the device now booting straight to TWRP, and not even attempting to go the normal boot route. I've also tried a Kindle Fire Unbrick Utility to restore it, with no luck. It wipes the User Data, wipes cache, downloads the update.zip, but can't mount the unit to push the data. I've never been able to get ADB to find the unit.
If I can get the update.zip to the SD root, or if I can ADB shell it, I think I've won. But I'm being blocked on both those counts.
Thanks for being willing to look into this for me!

the problem is the ics launcher - it simply don't work
would recommend to use go launcher instead, for the future
now to the problem:
one solution is to boot to twrp - there is adb root access available
maybe check and update drivers - look here:
http://forum.xda-developers.com/showpost.php?p=22342376&postcount=6
then delete the ics launcher .apk (don't know the exact name) with adb commands
this should make the kf startable again and nothing is lost
an other solution is to flash a new rom but i don't think that this is necessary
and never ever flash the original rom from amazon unless you want to return the device - there is a risk of bricking it and you will loose fff,twrp and root
there are prerooted stock images available for returning to stock rom:

You're giving me a lot of hope. I'll give this a try when I get home tonight, and I'll contact you with any other hurdles. THANK YOU SO MUCH!

halfway there
Ok so I have run the command under the adb shell after adb did detect the device, however when I run the command it says that "non existent directory" What am I missing?

echo /dev/block/mmcblk1p1 > /sys/devices/platform/usb_mass_storage/lun0/file
/sbin/sh: can't create /sys/devices/platform/usb_mass_storage/lun0/file: nonexis
tent directory
Getting that when i try to issue the command,
Any hint?

[Q] Demo Kindle Fire ADB Help

I know that this has been gone over multiple times, but I can't get any of the other threads to help so I figured I'd post my own.
Basically, I worked for Best Buy for awhile, rooted the demo Kindle Fire we got at work and that was that. So I figured I could get a demo Kindle Fire off Ebay and just get it rooted and Rom'ed. Well, I can't get the damn thing to be recognized by my computer in ADB.
I've literally tried everything, I've changed the android_usb.ini file to include the 0x1949 and the other file to have the kindle fire in it. Then I tried to point the Kindle to the new file that was changed. Everytime I update the driver it stays as the MTP Device and I can't get it to ADB Composite. I've tried the KFF and that doesn't work either. Uninstalled drivers and reinstalled with no success.
Also, it seems that every time I plug the Kindle into the computer it reinstalls the Drivers.
I do have a Factory Cable on the way so I'm hoping that that will work for me if nothing else does.
Thanks in advance all.

As long as the factory cable you speak of is the fastboot cable that is all you will need. Simply get it into fastboot, flash FFF and TWRP, transfer a Rom.zip and Gapps.zip to the sdcard, do a full wipe in recovery minus the sdcard/external storage. Flash Rom, flash Gapps and reboot. if you get it properly into fastboot your driver will read Android ADB interface. If your running windows 8 you need to disable driver signature verification in order to install the driver.

Thanks! It should be here today so I'm excited. I read all of what you've posted multiple times now in other threads, I just haven't been able to get it into fastboot so I'm really hoping that fastboot cable works for me.
Thanks for the quick reply Pooch.

Well. It's bricked. Couldn't get it to boot into twrp. After trying for awhile I decided to just flash fff as I knew the recovery was there. I get nothing now. Completely black screen and no led on power button. I've tried the whole firekit short usb with no luck. It gets past the first part but then just sits at waiting for device. So I'm lost. Is it fried?

[Q] Multiple devices problem while trying to root Kindle Fire

Hi All,
First up the device is Kindle Fire 3.6.2, and im on Windows 7 64 bit.
I first tried using KFU to start the root, but KFU kept hanging when trying to reboot in FastbootMode. The Kindle WOULD boot to fastbootmode, but then KFU was frozen on the line that said somthing like "rebooting to Fastboot mode". It then explained to turn off and on your kindle if it gets stuck, which i did numerous times, but it KFU didnt resume the batch file.
So, I have been following the Guide here:
http://forum.xda-developers.com/showthread.php?t=1638452
And i was able to succeffully install TWRP and backup my system, but TWRP keeps getting frozen on "updating partition", so im not confident that the Backup was successfull, however I can see the backup when i reboot the device in TWRP.
Now im attempting to use the Next few steps to root the kindle, specifically this step:
adb shell mount system
But adb says:
Error - more than one device.
When i query devices I get (shortened for clarity):
123 device
123 recovery
Im not sure why each of my steps have been sooo difficult to root my kindle! I really just want to experience Jelly Bean for the first time in my life!
Is there any tool at this point I can use to do the steps for me more easily? I tried KFU again but it always freezes after rebooting in fastboot mode,
If no tool is available, should i somehow disconnect one of the devices in adb? (I dont know how too).
BTW - I have no other devices other than a mouse attached to my PC!
Thanks so much in advance.
Regards,
Dale

Please, anybody? Ill be very grateful for any help!

First of all, when using adb (especially in Windows), always start every adb session with the command 'adb kill-server'. This will prevent previous adb sessions from staying active and causing problems down the line, like with the "multiple devices" error you are receiving.
Also, "updating partition details" in TWRP recovery takes only about a split second, but for some reason doesn't specifically let you know when it's finished. Your backup is in it's place so there's nothing to worry about. Beyond that, you shouldn't be having any problems whatsoever. Your adb shows connected in both normal and recovery modes, which suggests you have access to both, so your problems are all but non-existent.
And finally, you don't need to waste your time trying to "root" your device. When you flash a custom ROM in recovery, it gives you "root" automatically, so all you need to do at this point is use adb to push a ROM to your sdcard, factory reset in recovery, then flash the ROM (and Gapps, of course).

Uncheck the backup of android secure and I believe it will stop hanging at updating partitions.

[Q] Can't find Kindle Fire on PC when in Recovery

Hello everyone!
A few days ago, my Kindle Fire crashed during use and I could not get it to reboot. I reflashed the ROM I used that I kept in /sdcard (now I realize that I should have done a factory reset beforehand, but, alas, that's in the past) and could not get it to boot, so I connected the thing to my PC and tried to just get the stock ROM back on with KUU, but it failed to write it while in fastboot. In fact, fastboot seems to fail to write any update.zip, as doing it from terminal gives me the error "android-info.txt or android-product.txt not found in archive". Of course, now I decided to be an idiot and perform a wipe, including the ROM from my /sdcard folder in it. This wouldn't be as big a problem if I had access to ADB; however, I don't. When in TWRP 2.5 Recovery, the device doesn't show up at all under Device Manager, neither as "Kindle" or "Android ADB Composite Device". Therefore, I can't use adb push to have a ROM to flash. Seems peculiar to me, since I can access fastboot just fine, albeit under the name "Kindle Blue Fastboot Mode | Gen 1" instead of "Android ADB Interface" (I assume FFF 1.4a is installing some driver hidden in it's files?) I also attempted to use USB Mount to just drop the zip onto the Kindle, but it did not show up on my PC either.
This leaves me with three possibilities, unless you guys think of a fourth one.
1. Activate ADB for my Kindle in recovery, somehow (you'll need to direct me how to even touch this).
2. Use fastboot to put a ROM on (again, either someone needs to show me how to get fastboot flash update update.zip to work, or possibly there's a way to push files in here too?)
3. Use USB OTG in TWRP to install a ROM. I'm not even sure if this is a thing that's supported, but I'll try after I get a little more juice in the tablet (Edit: doesn't seem to work, sadly :crying
Thanks so much for viewing this thread, I hope one of you has some insight on how to fix my problem

"fastboot flash update.zip" doesn't work on the KF btw.
I haven't had a chance to look at hardware IDs or see how KFU's drivers are configured these days, but it may serve you well to use fastboot and install an earlier version of TWRP. Maybe a 2.4.x version to start out with...

Rolled back to 2.4.4.0 and 2.2.2.1, no dice
Edit: I did buy two new Micro-USB cables, should I wait until I get them to try and get my Kindle recognized by my computer? This person did the same (http://forum.xda-developers.com/showpost.php?p=25896517&postcount=12) and I feel like when I can get ADB to run, I can fix everything from there. It just seems odd to me that Fastboot would be recognized and the tablet can charge when in recovery on the same cable, it just can't access ADB.

Got the new cables today, still nada. Tried on my Win8 desktop, Win7 laptop, and Ubuntu Laptop, and none of them even showed that a device was plugged into it in recovery. Any other tips before I try to get Amazon to replace this thing?

Any further instruction I should try? I really want to get this thing in operation...

[Q] Stuck at boot, ADB not working

I was looking to do a full wipe from TWRP and wanted to wipe data as well. Knowing that that would erase everything from the internal storage and not having an SD card available to me now I decided to wipe everything and then transfer the new ROM with adb commands.
Before wiping, I wanted to make sure that adb was working first. So I downloaded the Android SDK and booted to TWRP. Went to Advanced--->ADB Sideload and started the command prompt on my PC. From the folder were adb.exe was I typed "adb usb" and got error:device not found.
I don't know why but after 30 minutes trying to fix that I pressed the "Fix permissions" option in TWRP and now my phone is stuck at the boot logo every time I try to turn it on. I also noticed in Device Manager on my PC that every time I connect the phone to the PC that there is a yellow exclamation mark next to the phone which suggests that I don't have the needed drivers. However I tried to install versions 3.10 and the newest 3.12 and the exclamation mark is still there.
So my question is how do I reach the phone with ADB and transfer the flashable ROM zipfile so I can get the phone past the boot logo?

Well I'll answer myself if anybody has the same problem in the future. It was obviously the USB driver's fault and since none of the LG's drivers worked, I used Google's USB drivers and was able to adb sideload the ROM zip and now it's booting into the OS.
So always check your drivers people! In case LG's don't work, then use Google's!
