[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:

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] Kindle Fire stuck at TWRP

So I formatted my rooted kindle fire with twrp installed, now whenever I boot I go straight to the TWRP menu, why can/t I boot into a fresh stock ROM?

i assume you told it to boot to recovery (in cm7)
you can use kfu option 1 - bootmode normal
or manually:
adb shell idme bootmode 4000
adb reboot

I'm having the same problem, I went into KFU and set option 1 and it shows this
***********************************************
* Activating Normal (4000) *
***********************************************
but doesnt go any further
When trying to install a ROM it says....
E:Cannot load volume /misc!......but it's right after it says that the ROM was installed
where do I insert the command for adb...........for KFU it is reading the Kindle Fire but for some reason when trying to set option 1 it doesn't go further.
It might be good to know that I deleted alot on the Fire in Windows explorer before this happened. Right now on my Kindle fire my
folders are Android, .android_secure, LOST.DIR and TWRP
files are fix_permissions, 3 ROMS, lol- Databasefile, and .config_c38
Any help would be GREATLY appreciated

In ADB should fix both of y'alls problems

sweetness, Not only did I just learn how to actually use ADB, but it also worked
THANKS

ok that worked great. But any idea why this is happening and how to avoid it from happening in the future?

I'm having the same problem, with "activating normal" stuck.
I also cannot input the command input adb shell idme bootmode 4000 or adb shell in command prompt.
It says that 'adb' is not recognized as an internal or external command.

it's a good practice to move kfu to c:\ and rename it to "kfu"
now open a (elevated) command prompt and cd to c:\kfu\tools
now the adb command should work ...

I am having the same problem here is exactly what i did
rooted
installed android market
installed twrp
made backup in twrp
flashed ics
wasnt happy with the performance of some apps on ics and there were quite a lot of stalls and complete freezes so i used the backup i made in twrp to restore back to original kf rom
most of my apps wouldnt worked and asked me to reinstall them through the kf market. i was unable to access the kf market or the android market as it said there was no connection and to retry even though i could access my email through mail and the internet through browser no problem.
then i decided to do a factory reset through kf rom settings and now twrp starts automatically anytime i try to turn on the kf. i tried to do the recovery again with the backup but the restore factory settings had obviously deleted it along with everything else on the sd card.
has anyone any ideas on how i can get back to the stock kf rom? I am happy with stock kf until hardware acceleration works with ics
thanks in advance

You need to flash a new ROM. If you need to go back to Amazon stock ROM, then you need to download and flash it. Please note FFF and TWRP will be over written by the stock ROM.

thanks for the reply
I just tried to do this. i mounted the kf and moved the stock rom .zip file to the kf. when i mounted it however instead of seeing the usual list of files and folders and selecting the cdcard folder i could only see the twrp folder and nothing else. when I am in twrp i can see the other folders but not when it is mounted to the computer.
i tried anyway and there were numerous errors in the process that i didnt have time to write down
now when i start up the kindle fire it stops on the kindle fire logo screen
any ideas?

It looks like the KF is booting into fast boot mode.
You may use kfu to change the mode to normal or issues the following adb commands
fastboot -i 0x1949 oem idme bootmode 4000
or
fastboot oem idme bootmode 4000
then fastboot reboot
If the KF boots to recovery mode i.e. twrp then mount the sdcard and flash the desired ROM.

I have been working on this for over four hours. I have done absolutely everything that is said to do.
Heres my symptoms:
Turn Kindle Fire on and i get the yellow triangle, after a few seconds I get the curtain that says "teamwin" then it just opens TWRP. I cannot get it to boot normally.
I have SDK and ADB. This is the last screen I got from ADB.
C:\Users\Jeff\Desktop\android-sdk\platform-tools>fastboot -i 0x1949 oem idme boo
tmode 4000
< waiting for device >
When I try to do it thru KFU:
ADB Status: Offline
Boot Status: Unkown
I tried hitting 1 then 1 again and all I get is <waiting for device>
The Kindle is just sitting here with the TWRP screen on and I have no idea how to get around it.

Fastboot only works in fastboot mode (4002). When you are in recovery or booted into an OS, you have to use adb to reset the bootmode. To get back to normal...
Code:
adb shell idme bootmode 4000
As a side note, the "-i 0x1949" should be dropped when you are using the FIREFIREFIRE bootloader (yellow triangle boot logo). The "-i 0x1949" is only necessary in the stock bootloader (kindle fire boot logo).

You're quoting someone from early March. I'm guessing you probably wont hear from them very soon.
On the other hand, if you're willing to start a new thread and explain in great detail what your "similar" problem is, I'm sure you'll be pleased with the quickness in which somebody responds.

OSX: Kindle Fire, Rooted stuck on Fire screen loop after apk

Hello. After a few attempts I was finally able to root my kindle fire using Breakdroid found here: http://forum.xda-developers.com/showthread.php?t=1511757 .(I only have access to an OSX, no windows). I have a dell latitude running snow leopard. (hackintosh)
I can get to the black and red screen.
I downloaded the energy ics apk and tried to install the zip through the CWM-base Recovery v5.0.2.7 FULL (by DooMLorD) and it just loops through the fire screen with the triangle logo. Occasionally you can see the ICS startup screen, but very briefly(like 1 sec) but it goes back to looping through the reset.
I am not new to rooting android devices as I have rooted my phones in the past with no problems.
1. What am I doing wrong?
2. I can try install TWRP but how?(step by step on overwriting the CWM-base Recovery in OSX please, i have adb and tried but it does not see twrp in my file location.
3. is there an updated script for osx that auto installs TWRP?
If someone has time, please post a video please as there are none on installing using OSX on a fire using 6.3 on youtube or anywhere else on the web.
I cant add a new post since im new so Im editing this one:
Thanks! After waiting 15 min for the opening ICS screen, I finally rebooted and had the same problem..
Now the big question... how do you install TWRP using OSX?
tell you the steps I have done with no success...
I went to http://www.teamw.in/project/twrp2 and chose kindle fire
downloaded the .img and placed it in my platforms-tools(and yes, I downloaded the ADB package and added platform-tools)
first did adb devices and got:
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
436E000600000001 recovery
then followed the websites direction and started adb shell by typing adb shell and got:
:~ drive$ adb shell
~ #
then followed the websites direction and entered su and got:
~ # su
/sbin/sh: su: not found
~ #
why was su not found?

Think I might gotten closer to a solution to my own problem.. I re-rooted using Breakdroid(auto root method) and now I am getting the full ICS animation screen ... Im going to leave it alone for a bit and see if it actually loads ICS on my fire.. will let you know any findings...

TWRP is required to run the new ICS roms. CWM usually will not work.

ok.. got su to finally work after reloading kindle fire's image that I did a backup of and let it be on USB mode
got bootmode to go in from the site
tried to fastbook and i get:
# fastboot -i 0x1949 flash recovery openrecovery-twrp-blaze-2.1.1.img
fastboot: not found
.. Edit.. found out that fastboot requires that you exit out of ADB..
now fastboot stuck on 'waiting for device'

You don't need "su" to enter fastboot commands.
While in recovery, enter:
adb shell idme bootmode 4002
adb reboot
That will restart your kindle in fastboot mode. Then you can enter:
fastboot flash recovery /path/to/twrp.img
Then...
fastboot oem idme bootmode 4000
...and reboot

EDIT:
6.3.1
Wow.. what a pain! Finally got TWRP to load! Here are the instructions for OSX using http://forum.xda-developers.com/showthread.php?t=1511757 (since no one seems to have it)
download breakdroid
start breakdroid (not kindlewater)
press 5 for kindle
press ok
press 1 for autoroot
now this is where you either get it or not.. my first time I got hung at waiting for device, so i simply unplugged it and replugged it and continued the autoroot. The second time after i unrooted my kindle fire and rerooted I did an exit and re rooted and it went all the way through... so your choice...
after you should be able to load kindle fires normal os after you see a triangle with a fire in it
now download TWRP
head over to: http://www.teamw.in/project/twrp2 choose kindle fire from their
'please select device'
download their .img
follow the instruction here to add adb to your MAC: http://forum.xda-developers.com/showthread.php?p=9842005
with the instructions, make sure you do it step by step including the "Now .... I am going to show you how to make your life a lot easier in Terminal to run ADB without having to navigate to the folder every time you want to launch it."
if you did the instructions correctly you made a quick way to start ADB.
you can check if it works by starting a terminal(under applications/utilities(i made a quickstart and pinned it to my bar) and type ADB devices(with caps)
you should see your device there, if not, retrace your steps
move the TWRP .img file to your platform-tools folder
now start your kindle fire to normal mode and plug in your usb.. leave it on USB mode, do not exit
start a terminal and type ADB devices, your kindle fire should NOT be in recovery, should show 'device'
follow the TeamWin directions and type adb shell
type su
type idme bootmode 4002
type exit
quit terminal
restart terminal
type fastboot -i 0x1949 flash recovery openrecovery-twrp-blaze-2.1.1.img
your kindle fire will look like it is locked up after a few min, simply power off your kindle fire after installation of TWRP by pressing the power button until it turns off..
power back on and press and hold until it turns orange, release..

Kindle Fire. Device Manager Sees but Kindle Fire Utility Doesn't

My Kindle was rooted but I decided to try my hand at installing a custom ROM. However, the ROM I tried would not work and the screen stayed black. However, thanks to TWRP I could install Kindle from Amazon again. The installation went thru smoothly, or so I thought. Now, when I boot the Kindle, I see the Kindle Fire Logo and it stays there. The Computer can see the Kindle as an Android device, Android Composite Device. But Kindle Fire Utility cannot see it so I could try and re-install it again. Any suggestions?

Lacking information, so I'll just fill the voids with assumptions.
I *assume* you didn't wipe cache, dalvik-cache and most important when switching from a ROM to another, Factory Reset - this is the reason said custom ROM wouldn't work, and the reason flashing back update.zip (as you said you installed it, rather than restoring a backup) caused your KF to get stuck in a semi brick.
The most important question here is, do you have FFF installed?
If you do, fixing this is trivial. Just get into TWRP from FFF, wipe cache, dalvik-cache and factory reset and then install whatever ROM you'd like to try or use.
If you don't have FFF installed, then your solutions are to either get a factory cable (recommended) or to crack open the case and do the USB pin short trick. From there you can use fastboot to install FFF and boot into TWRP.
Alternatively, you can try "fastboot getvar product" or "adb shell idme bootmode 5001" to see if you get lucky.

Alternatively, you can try "fastboot getvar product" or "adb shell idme bootmode 5001" to see if you get lucky.

I tried the USB pin short trick but now my Kindle won't turn on at all nor will it charge. Thanks anyways!

i have similar problem ......please need help
After successfully rooting kf with kfu and making a backup ... I did factory reset and flashed a custom rom ... now kindle is stuck on " kindle fire" logo and just keeps flashing and rebooting . My computer recognizes it as android phone ( android adb ) and kfu does too but only for a couple of seconds . During those few seconds I try recovery ... fast boot ...normal boot... n none seem to work . Kf just reboots n returns to boot loop . Any advice is appreciated .. thanks

What colour is the "kindle fire" logo when you turn on your KF?

Force Kindle into Fastboot
Ok, so I have finally got my Kindle to turn on, using the USB Short Trick. Now my only question is about getting the Kindle to boot into fastboot mode so I can re-format the sdcard partition and finally load a new ROM. I have tried several different commands and they all seem to miss the window of opportunity to start the kindle in fastboot mode. Is there any way, short of a factory cable, that one can make the kindle start in fastboot mode?

Not fastboot get var

fastboot getvar product doesn't seem to do the trick. The kindle seems to be in fastboot mode but the adb shell cannot access the device.

The problem is that you don't have the fastboot drivers installed (also, ADB will not work while fastboot is active) - Windows is painfully slow at detecting a device and installing its drivers, so by the time it even notices anything, the fastboot window is already over.
To solve this, use firekit: http://forum.xda-developers.com/showthread.php?t=1430038
The script that will probably suit your needs the most is usb_install_fff_twrp.

I have TWRP and FFF installed. However, upon booting into TWRP, the sdcard partition cannot be mounted, to the Kindle that is, and as such, I cannot mount the sdcard to the computer. When I researched this some more, I found that I can fix this by using a command via adb shell. The guide instructed using fastboot to achieve this. When would be the best time to use adb shell?

What's the output of partitions.txt? (type the following from TWRP)
adb shell parted /dev/block/mmcblk0 p > partitions.txt

Can't use adb

The problem at hand is using adb. I can never time it exactly right to open adb. I always get an "error: device not found". Windows even recognizes that Android ADB Interface is plugged in.

Okay, things are getting awfully confusing here.
What exactly is it that you can do and that you cannot do?
For example, are FFF and TWRP functional?

GOT IT!
Thank you! I finally figured out that the wrong driver had reinstalled and that was causing my computer to not be able to use adb shell. I fixed that and voila, I am now running CM9. Thanks again!

Kindle Fire stuck in TWRP boot loop, wont mount, not recognized.

I foolishly let someone try to root my Kindle Fire, and now it is stuck in what seems to be the TWRP boot loop (the kindle fire is blue and white). If I leave it alone unplugged it will occasionally continue to the Kindle Fire orange and white screen but will not go any farther. From the Blue/white screen I can hit the power button to enter the boot menu where I get Normal Boot, Recovery, and Reset Boot Mode. I can enter TWRP recovery menus, but otherwise it just keeps rebooting. Once in the TWRP recovery screen I can only navigate for a short time before it locks up and I have to reboot by holding the power button in. The sd card will not mount, and they did not backup anything before they started messing with the os. Ive tried the Kindle Fire utility but it says device not found. The Kindle showed up in my device manager as Other-Kindle before I installed the android drivers mentioned in another thread, and now it is under Android Phone- Android ADB Interface. It doesnt show up in My Computer at all. I've read about the factory cable but cant find on in the US so it would take 2 weeks to get here from China. Any suggestions on how to fix this, or do I now have a $200 paperweight? Thanks in advance.

Maybe go into twrp and do a factory reset. Can you get to that menu? Click wipe and then factory reset.

I've tried the factory reset but it seems to have no effect on it. How do I do the adb push? I've tried using the command prompt to run some of the commands on other threads but I'm not doing something right. I always get an 'adb' is not recognized as an internal or external command, operable program or batch file error.
I'll apologize now for my stupidity on this one- I have never worked with android software before this.
The kindle fire utility reads:
ADB status: Offline
Boot Status: Unknown
I can get it to boot in normal and recovery mode, but each time I try to boot in Fastboot I get an error message 'Oops... something went wrong. We are unable to locate your Kindle Fire. Make sure it is plugged in and powered on.' The Kindle shows up in Device Manager under Android Phone as Android ADB Interface
When using the twrp, anything that involves writing to or wiping the sd card receives this error E:failed to mount /sdcard (invalid argument)
I'd appreciate any help I can get. I'm at a standstill on this one.

im in the same position you can open it as a USB by selecting mount in TWRP and selecting mount USB Storage

do you have drivers / ADB on your computer ?
I did manage to get my kindle go into a recovery boot loop by doing the root procedure for the original 6.3 original Amazon ROM while my kindle had the 6.2 ROM . After i realized that the root procedure (intended for ver 6.3) didn't work for me, I had to try the procedure for rooting ver. 6.2.
It worked but after a couple of resets, the tablet went into a recovery boot loop.
what i did was to use ADB comands:
enter windows - > start command prompt (start - > run -> cmd)
check if kindle is connected: adb devices
if the device is found then use:
adb shell
su
idme bootmode 4000
exit

Hi all, I'm having a problem with my Kindle Fire. It is automatically booting into TWRP no matter what I do.
I have wiped everything, and installed the stock ROM, and when I reboot it just goes back to TWRP.
There is always a message of *verifying file system and *verifying partition. I can mount it and move files via USB.
In the fire utility it reads
ADB Status: Online
Boot Status: Unknown
If I try to change the bootmode it comes back waiting for device. I then got into the command line.
Doing "adb devices" shows it as being in recovery. I can reboot it from here, but goes right back to twrp.
I tried to do the adb shell--> su--> idme bootmode 4000
but after I do the shell it comes back that "su" isn't valid. I'm assuming I am doing something wrong, but I can't
for the life of me figure it out...any suggestions? Thanks in advance!

At startup hold thepower button untill you see the bootmenu come up and select "normal boot"

On the Kindle itself you mean? There is no bootmenu. I get the Kindle Fire (Orange) text, then goes straight to twrp, and if I do normal reboot from there, just straight back to twrp.

What version of TWRP do you have?

2.2.0

From twrp try booting into recovery that worked once for me to get a normal boot. Then make sure you put the fire fire fire bootloader on there so it never happens again

Tried it, no go.

This is what I get in the command line

The "<[6n" is likely the result of pressing the up or down arrow with number lock turned off and it is causing the command to be unrecognized.

Regardless, there's no need to use the "adb shell su -c..." command to get into fastboot. Instead use Pokey9000's bootmode binary "fbmode".

As you can see, the "adb shell" command is successful because of the change in the prompt.
~ # <-indicates the shell is working and active, so the actual /path of adb is irrelavent.

That seems promising, but this is what I got when I tried it.

Also, thanks for your help everyone, I'm learning a lot as I go here!
