remount failed?? - Kindle Fire General

remount failed?? - Kindle Fire General

Problem fixed !!! Thansk!
Any ONE can help?
My kindle fire already rooted, every time i want to install the input method by adb remount is fail.
remount failed: operation not permitted!
how can i fix it??

would thing you get the $ prompt if you open the adb shell
enter "su" - the prompt should change to #
then the remount command should succeed

enter "su" - the prompt should change to # in shell mode
then type : # adb remount ?
could you get me a detail command set ?. because kindle fire is my first's android device , BIG THANKS!

this should be the way it works:
adb shell
$ su
su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
#
the bold commands are the ones to enter ...

My file is saved in c:\apps\hk.cedime.inputmethod.apk
and also have a copy in c:\adb\hk.cedime.inputmethod.apk
Show many error ??? Any expert can help?
adb shell
$ su
su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
# install c:\apps\hk.cedime.inputmethod.apk /system/app/
install c:\apps\hk.cedime.inputmethod.apk /system/app/
install: can't stat ' c:appshk.cedime.inputmethod.apk' : No such file or directory
# install hk.cedime.inputmethod.apk /system/app/
install hk.cedime.inputmethod.apk /system/app/
install: can't stat ' hk.cedime.inputmethod.apk' : No such file or directory
#cp hk.cedime.inputmethod.apk /system/app/
cp hk.cedime.inputmethod.apk /system/app/
cp: can't stat ' hk.cedime.inputmethod.apk' : No such file or directory
#cp c:\apps\hk.cedime.inputmethod.apk /system/app/
cp c:\apps\hk.cedime.inputmethod.apk /system/app/
cp: can't stat ' c:appshk.cedime.inputmethod.apk' : No such file or directory

install: can't stat ' c:appshk.cedime.inputmethod.apk' : No such file or directory
Click to expand...
Click to collapse
it don't find the .apk file
i use to put the files to install in the directory where adb.exe resides
and do the command without a path ie: install hk.cedime.inputmethod.apk /system/app/
furthermore i'm not shure if the command works inside the adb shell
would also try (from command prompt):
adb install c:\apps\hk.cedime.inputmethod.apk /system/app/
or if .apk in current directory (where adb resides):
adb install hk.cedime.inputmethod.apk /system/app/

Adb command is my first choice
But the system show the error : can't find '/system/app/' to install

then it seems not to be mounted ...
try to check with:
"adb shell"
"su"
"mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system"
"cd \system"
"ls -l" -> any directory listing here ?
"cd app"
"ls -l" -> any apk's listed ?

OH! my God!

no problem - if it's not mounted it's hard to remount
would try:
"mount /system" in adb shell
or
"adb shell mount -o remount rw /system" from the command prompt

from your post #5:
adb shell
$ su
su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
Click to expand...
Click to collapse
this has seemed to work - or was there allways a error message following up which you did'nt copy and paste ?
usually "mount /system" is sufficient - "mount -w /system" should work too
# cd app
cd app
cd: can't cd to app
Click to expand...
Click to collapse
if you look to the directory listing you are on the root - there is no directory or mountpoint "app" - it is in the system directory - the command should be:
"cd \system"
"ls -l" -> any directory listing here ?
and then if you are in "system"
"cd app"
"ls -l" -> any apk's listed ?
as in post #8

Expert ! Next step what can i do?

as you run a unsecure kernel i think the command should be:
adb shell su -c "remount"
or
adb shell su -c "mount -o remount rw /system"
C:\ADB>adb shell

the second attempt succeeded - so your question seems to be answered or not ?

[Q] [Help!] Apss directory permissions messed up and I think I bricked my kindle

HI,
I need big help, any comments are appreciated.
I was rooting my kindle again after 6.2.1 update.
Everything was OK, until I changed the /system/apps folder permission to r/w for all users using file exporer.
After that, I started not to be able to launch anything.
I tied to reboot and my kindle now stuck at the screen saying "kindle fire" and it flashes every 10 secs or so.
I tried Kindle_Fire_Utility_v0.9.1 several options with no success.
I can connect via adb and see the directories but I can not do adb root.
It mount the files system as read only.
c:\Program Files (x86)\Android\android-sdk\platform-tools>adb root
adbd cannot run as root in production builds
It is almost like, everything is fine but the system can not find the apps to run.
Is there any way I can recover?
Here are directories and permissions:

I can not do su, I can not reach any directory. (including sdcard).
I can not do even whoami:
$ whoami
whoami
whoami: permission denied

as a first step you could try if this is successfull:
adb shell
look if your prompt is $ or # - if it is $ type su - must change to #
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
chmod 755 /system/app
if not you can try to install twrp (if you not allready have)

and flash a backup, the stockrom or one of the roms available in the forum

HI Thanks for the reply.
adb shell works and prompt changes to #
su does not work.
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
chmod 755 /system/app
does not work, says I don't have the permission. I think this is because of readonly file system.

have you tried the second solution ?

I will try tonight but, I am not sure whether it will work. Because, if I am not calling wrong, I tried to get into data directory last night and could not.
But I will try tonight again and will let you know.
Thanks again.

Second solution works, I fixed this same problem that way.
BUT. Be careful what you do next, as I flashed the stock rom and now my Fire is bricked again and with a non working adb. So, again, be VERY CAREFUL

osozraz,
So given you experience, which rom should I use?

absolutely right ! - i would suggest one of the prerooted stock roms from here

I can´t say, as my Fire is still bricked and that was the first rom i installed. For my experience, DON´T flash the stock rom.

Thanks a lot for all the help.
The solution about fbmode in the following thread is worked:

Then I installed TWRP using Kindle Fire Utility v0.9.1:

[Q] Need a tad bit of help with using commands

K, i've got a wii emulator, but i don't understand how to run these commands !!! +_+
To increase stability on Galaxy S4 and other Adreno 3xx devices with driver v14, you need to root and run the following commands on the device as root.
Code:
echo 0 > /sys/kernel/debug/kgsl/kgsl-3d0/fast_hang_detect
echo 0 > /sys/kernel/debug/kgsl/kgsl-3d0/ft_pagefault_policy
echo 0 > /sys/kernel/debug/kgsl/kgsl-3d0/ft_policy
echo 0 > /sys/kernel/debug/kgsl/kgsl-3d0/ib_check
echo 0 > /sys/kernel/debug/kgsl/kgsl-3d0/long_ib_detect
Can someone please educate me on how this is suppose to work? do i need an android terminal? or how do i go about running these commands?
(yes my phone is rooted)
Thanks
Ryan

These are system commands and you need to run them from the "command line". The easiest way to do that would be to install a terminal application. Android Terminal Emulator by Jack Palevich is one good choice. Or you could run an adb shell.
After you install terminal emulator, enter
su [enter]

"su" is the command for superuser (root access). Then you can use the system configuration commands that you have for your wii emulator.
If any commands need to be reentered each time you use your emulator, then you could use a scripting app like gscript light which can be configured to enter these commands from a bookmark. i.e. just click on a bookmark and it will run a set of commands for you.

Hi,
Thanks for replying!!! I've a problem though , after i enter su (enter) then grant superuser, i type in echo 0 > /sys/kernel/debug/kgsl/kgsl-3d0/fast_hang_detect
then i get no such file or directory , what am i doing wrong???

Do you have those directories on your phone? Where did you get the commands to type in? Are they specific to the s4?

I got the commands from here https://forums.dolphin-emu.org/Thread-opengl-es-3-guide i apologize if im not supposed to post link +_+

I can't add much more than jd1639 already suggested. These commands would just make a temporary configuration change to half a dozen driver settings in aid of your emulator program. The "echo 0" command ensures that a particular setting is set to "0", if the target file exists.
Check for typos. If there weren't any typos, then it would seem likely that the information from the original thread is inaccurate or out of date. What model of phone are you trying this on? The original thread refers to the i9505 and similar phones. Is your phone a i9505? The fact that you're posting this in an AT&T, et al forum suggest that you might actually have a i337 /i337m phone. Depending on what model you actually have, your phone may have a Snapdragon 800 or Exynos processor rather than the Snapdragon 600.
The drivers may or may not be the same across different phones and processors. Or the drivers names may have changed in a subsequent firmware update. You check your filesystem to see if those paths exist or if the file names can be found elsewhere. Then look to the emulator thread for further guidance.
I had a quick look at a S3 and some, but not all of those files exist. If you find the same thing on your S4, then you'll have to refer to the emulator thread to discern if you need to have all of those items to enable your emulator or if a subset will suffice.
You can probably just create any "missing" files for a workable solution. They're just text files that the drivers refer to for guidance. It's something that I'd at least try in your place. However while I don't perceive any real risk in that i.e. worst case it wouldn't boot and you'd need to restore a backup.. don't look to me if your phone unexpectedly wimpers, fails or becomes sentient and disagrees. Anything you actually do is at your own risk.
You can search paths and file names as follows below. And you should be able to use the touch, mv or cp commands (or install a text editor) to create a missing file.
$ su
# cd /sys/kernel/debug/kgsl/kgsl-3d0
# ls -la
# find / -name fast_hang_detect

Hi, I have the I337m variety of the Samsung S4 will that make a difference?

The answer to that will be in your emulator thread.
More to the point, you haven't done your homework yet. Do those paths and files exist on your phone? Does the emulator thread clarify if all of those settings are required? And did you try creating any missing files? People are trying to help you here, but we can't see what your phone screen actually shows. And you should be doing most of the work to see what does or doesn't work.

That is what i get, for the life of me i can't figure out if that means i have it or i don't. "On the Thread it says To increase stability on Galaxy S4 and other Adreno 3xx devices with driver v14, you need to root and run the following commands on the device as root."
So I'm assuming i require all of them to work in order for any difference. Certain sites list the I337m varient as one of which supports Open Gl ES 3 so i assume it would work

All right, I can understand how a lot of this might be a challenge to understand if you have no experience with linux. But you at least need to make sure that you aren't making typos when using these commands.
e.g.
[email protected]:/ # find / -namefast_hang_detect

You missed a space between -name and the actual file name. And yes, that is critical. Nothing here is likely to work if you have typos. Try the following and paste the results back here. And I or someone else will better understand what is going on::
$ su
# cd /sys/kernel/debug/kgsl/kgsl-3d0
# ls -la
(exactly as above and paste the result for us).
If you are ambitious then also try the following for any "missing" files and let us know if that succeeds in getting your emulator up and running.
e.g.
# touch /sys/kernel/debug/kgsl/kgsl-3d0/fast_hang_detect
# echo 0 > /sys/kernel/debug/kgsl/kgsl-3d0/fast_hang_detect
.

:S thanks i didn't know i had missed a space, and yea i have little to no experience with linux.

Wifi don't work? Flash this! /Persist Repair

Well, many people have problems on the /persist partition, maybe because some bad rom, or maybe because by a mistake you formatted them on a recovery (a bad recovery without forbid partitions).
Before this zip, you have to copy the "WCNSS_qcom_wlan_factory_nv.bin" to /persist manually, but some file managers don't mount well /persist.
But now, only flashing this zip, it will copy the file to /persist and Wifi go back to work.

Bro how to flash it ?
I flashed with twrp v3.0
it gave an error at the end. unable to mount something.
wifi is not working on my mot g2013. I have tried 5-6 roms.
Pls help

does it work?

No it dint.
Twrp gave error. Also the file whicg have to copy in that persist folder gets deleted automatically.

This works
OK, this works but not exactly by flashing.
First of all, this file is a WLAN Qualcom driver which is somehow missing after flashing errors.
Step by step:
1. Enable root for ADB in developer settings in your phone
2. Connect your phone with USB
3.
Code:
adb root
4. Now adb will reconnect as root. Enter command above again to make sure it's done (you will receive confirmation)
5. /persist is not accessible by default (read-only) so we must mount it as writable partition
6.
Code:
adb shell
7.
Code:
mount -o rw,remount /persist
8.
Code:
exit
- we are exiting shell now
9.
Code:
adb push WCNSS_qcom_wlan_factory_nv.bin /persist/
- we are copying driver to phone
10. OK, drivers are now saved on our phone. Let's remount /persist again to be read only:
11.
Code:
adb shell
12.
Code:
mount -o ro,remount /persist
13.
Code:
exit
14. Reboot your phone
If you have unsufficient permissions or something, try
Code:
chmod 777 /persist
after point 7 and
Code:
chmod 771 /persist
after point 11
Tell me if it works, was ok for me.

Zyzoom Hello, first of all sorry for my poor English, I have a XT1032 with the same problem, after installing TWRP recovery and CM13 Nightly 3.0.0, and was unable to enable Wi-Fi.
I followed your steps, but in step 9 out "Read-only file system", so I resume the steps from 6 (adb shell), then "mount -o rw, remount / persist" I write "chmod 777 / persist" but I back out the error " Read-only file system. "
Would you help me please?

norte112, you need to write commands exactly like I wrote. Do not put space between "/" and "persist" and between "rw," and "remount".
The best is to copy them directly to terminal, I think it's CTRL+INSERT or SHIFT+INSERT on Windows

The commands were copied and pasted as contained in the post directly to cmd, for an error when writing this query, add spaces, but just confirm again (no spaces) and still gives the same error message.

I found the problem, after writing the adb shell command, the console brings me the following result: ← 7 ← [r ← [999; ← 999H [6n
I just click on INTRO and I recently enabled the line: ← 8root @ falcon: / #
After that, I entered the commands and could properly install the drivers !!!
Problem solved.
Thank you very much for the support, help and above all, patience.

Worked perfect with flashify and twrp (copy first to a safe location)
Many thanks!

Didn't work for me
I tried flashing the zip, copying manually in CM file explorer and twrp and adb.
The driver is present in /persist but my Mac is stil 02:00:00:00:00

My wifi bug is kinda weird.
When I turn on and off my wifi 2-3times,the wifi I connected previously disappear.
Solution is to wipe everything including internal storage to have it working.But still I don't know what's the problem...

I had trouble installing the file no matter how it I flash the wifi did not return to work until I found a solution that apparently functioned normally every time I performed the procedure.
1. Make a full wipe on your smartphone (System / data / cache / dalvik and internal storage) I did the procedure using TWRP 3.0.2-0 on my bike G XT1033
2. Then copy the file persist_repair.zip and some version of CM13 I used (cm 13.0-20160708-NIGHTLY-falcon)
3. After placing the files in the memory of the first flash persist_repair.zip phone and then the CM13 (You can do using the option to install multiple zips the TWRP also the right)
4. Restart your phone and its wifi should resume functioning
Note: I performed the procedure 4 times here and it worked perfectly.

I faced same problem after flashed custom rom; searching high and low, tried many method, and finally, bumped this thread, and specifically NoobByn-tek post. I followed exactly what your have done (but with different version CM13 [cm-13.0-20160820-SNAPSHOT-ZNH5YAO0J1-falcon] because could not find the version you used), and multiple flashed with TWRP 3.0.2. With only one attempt, wifi connection is back.:victory:
Big thank you all.:good::good:

Then I installed a terminal app (can't find the link but it's called jackpal.androidterm.apk, can attach if needed) by putting it on a micro sd card and installing the file using relaunch (a file explorer app that appeared after rooting). Then I followed the instructions on https://forum.xda-developers.com/wiki/BN_Nook_Simple_Touch/Replacing_boot_files writing
su
mount -o rw,remount rootfs /
mkdir /boot
mount -t vfat /dev/block/mmcblk0p1 /boot
into the terminal app. It asked for permissions after su, which I granted and the other lines produced no errors but also no outputs. Now I am trying to find the /boot partition to replace uImage, as per the instructions, but I can't find /boot. It appears nowhere in the file explorer, and under advanced functions, the nook lists the following disks/partitions: /rom, /system, /data, /cache, /sdcard, /media, but no /boot
Any ideas? Really unsure as to why it's not showing up, because the commands that are supposed to create it seemed to complete without issue.
p.s. I also checked show hidden files in folders in the advanced settings

I dunno. Your "File Explorer" may be leading you astray.
Just do an ls -l in terminal and check.

ls -l produces:
drwxrwx--- system system 1969-12-31 16:00 rom
drwxrwxrwt root root 2018-02-26 11:11 sqlite_stmt_journals

drwx------ root root 2012-12-07 14:34 root
drwxr-xr-x root root 2018-02-26 11:11 dev
Further, I tried to copy uImage into /boot using the terminal and it acted as if /boot didn't exist, so I'm pretty sure that it isn't there for some reason.
Thanks

Well, something you're doing isn't working.
The commands are correct.
Code:
su
Did this work? Do you get a # prompt? Type "id", does it say you're root?
Code:
mount -o rw,remount rootfs /
Ok, did it remount? Type "mount" and see if rootfs is actually "rw".
Code:
mkdir /boot
Apparently this didn't work because you should see an empty directory at least.
Code:
mount -t vfat /dev/block/mmcblk0p1 /boot
Apparently this didn't work.

Did this work? Do you get a # prompt? Type "id", does it say you're root?
su produces a # prompt, and id produces: uid=0(root) gid=0(root), so i think this part worked.
Ok, did it remount? Type "mount" and see if rootfs is actually "rw".
mount produces: rootfs / rootfs rw 0 0, and then a bunch of other stuff, so i think this worked too.
mkdir /boot
this produces nothing, just another # prompt, so this might be the problem
mount -t vfat /dev/block/mmcblk0p1 /boot
this also produces nothing, just another # prompt.
Any idea why mkdir /boot would fail?
Thanks for being so helpful!

Well, the mkdir should have created an empty directory.
You should be able to "ls -l /" it.
If not, you could mkdir and mount anywhere.
Code:
cd /data/local/tmp
mkdir mybooty
mount -t vfat /dev/block/mmcblk0p1 /data/local/tmp/mybooty
There's nothing special about the name "boot".

Okay,
That solved the problem. Thanks for all your help!
