[Q] symlink to External SD Card - LG Optimus 2x

Hi,
I've just installed fresh CM10 ICS Nightly on my LG Optimus 2x. The original __EXTERNAL_SD folder in my Home was suddenly empty, so I thought the mount point of External SD has changed. I found it in /storage/sdcard1. However, Applications don't recognize that, because they obviously expect __EXTERNAL_SD simlink/folder (or whatever it is) in my home. So I decided to delete it and create a new one to new location. Deletion was successful,but I'm not able to create a new symlink.
Code:
[email protected]: /sdcard # ln -s /storage/sdcard1 __EXTERNAL_SD
link failed Operation not permitted
[email protected]: /sdcard #
This is what I get.
Furthermore, since I deleted original file, every time I start Apollo (music player) I get error Unfortunately, Apollo has stopped. That's kinda weird, because it acts like it requires working __EXTERNAL_SD, but I'm not 100% sure.
Can you please explain me how to create such a symlink? Thanks!

Have You tried with superuser?

Sure, sign # means I have root access. Anyway, the problem is not longer relevant for me, bacause I've reinstalled whole system from the bottom using factory reset.
I'm newbie to Android, and It's litte suprising for me that root can not create a simple symilnk, that shoul work every time (as in Linux).

[Q-Solved] CM7.2 and SD-Card Supported Apps

Hello,
I flashed Squadzone's CM7.2 RC5.5 yesterday for first time I use any custom ROMs on my SGM.
Then I flashed GApps and Opened market to install my favorite apps, here I noticed that (SD-Card Normally supported) apps were installed in Internal Memory.
Finally, I installed Link2SD, moved and linked all application to SD-EXT partition .. so all applications linked to SD-EXT.
I tried to move them to Normal SD-Card via Settings => Applications, but it failed.
I tried to move them via Link2SD, but it failed with Error: "[INSTALL_FAILED_CONTAINER_ERROR]", but it succeeded one time to move Acrobat Reader then it failed.
I don't bother if they are installed on SD-Card or SD-EXT, but this problem causes to bigger problem. the Following Apps MUST be installed on SD-Card from Market or APK (as I think):
1. Voice Search
2. Archidroid
3. SpeedCar
4. Holy Quran
when I tried to install them from Market, they prompts an error: "couldn't install on USB Storage or SD Card"!
although the rest apps installed successfully!
Sorry for my bad English, I wish I explained the problem successfully.
Hello,
I searched here and there and I Found a way by removing a temp file in .android-secure but it failed.
I monitored the logcat and found this:

Finally, I removed all system and application related folders from SD card via a computer. And wiped data and cash and started in a clean environment with English interface.
Then I succeeded, I discovered that the problem in Arabic interface so I tried many times to be sure!

Need som help to end Froyo on Kaiser install

Hello xda-kaiser-android community
My configuration is :
SDCARD with 4 partitions :
FAT16 with Haret, zimage, inird, default.txt
SYSTEM (ext2)
DATA (ext2)
swap
I've managed to launch Android, and the phones does work.
Unfortunately, at the moment, some other things does not work :
WIFI : fails when getting the IP (so I scan WIFI networks well, but there is a problemn when creating the network interface...)
Modem : does not work..
Camera : not very important for the moment, but can become more...
So, I wanted to dump log files and try, with the terminal, to guess what is happening, but I COULD NOT MANAGED to SU ROOT (as a Linux user, I don't feel comfortable when I cannont be root on my personnal machine)...
When launching the "SuperUser" program the Applist is empty ?
When I set suid and root:root ownership of /bin/su on the SYSTEM partition, when SD mounted on my computer, It is not preserved when used inside Android...
After some inspection of the init scripts (see here under), my question is :
WHY SYSTEM PARTITION IS NOT MOUNTED with ROOT privileges ??
WHY is it chowned to the user 1000:1000 ?
Code:
# mount and set perms
$BB mount -o noatime,nodiratime -t auto $PARTITION $SD_EXT_DIRECTORY;
if [ "$?" = 0 ];
then
$BB chown 1000:1000 $SD_EXT_DIRECTORY;
$BB chmod 771 $SD_EXT_DIRECTORY;
log -p i -t mountsd "$SD_EXT_DIRECTORY successfully mounted";
Thank you for your comments, any help will be appreciated
Regards
Bernie
I overpost myself : My problem probably comes from the way I extracted the Froyo tarball to the SYSTEM partition...
I'll try again and inform you of my mistake.
Regards
why don't you try FAT32 instead of FAT16

Don't extract the froyo tarball. Just place androidinstall.tgz and androidupdate.tgz into the SDCARD andboot folder. Then, after you boot linux, touch and hold the center of the screen, and an install menu will appear. Then select your partitions, install system (and format data partition), install updates, and fix permissions, then exit. Android should start. Be sure your kernel (zImage) and drivers (androidupdate.tgz) match, and it also helps for the initrd.lzma to match. When wifi doesn't work, that usually means the driver is mismatched.
Hi Guys
Thnk you for your answers.
I got a more urgent issue than porting my kaiser to android : I've been forced to move my laptop back to windows again ...
So I must know workaround to dual boot linux (and, believe me, this install of windows is not the standard one)..
But A soon as I can, I will try the install stuff.
thank you again
Heydiho !
Things get better...
I caught eu-froyo-odex and installed it as is after entering the installation menu (launched by init ?)... The su command is now working. I have to tackle a few things now :
Wifi works even worse (now I clealry see an error, where, with the other distro, it was probably a permission issue)
Screen has still odd behaviors
Keymap issue with Keyboard arrows does not work in terminal
And camera to be confirmed
I'll dig the forum for topics on these subjects and get back if I'm really stuck
Best regards
Bernie
Hello
Things goes in the good direction :
Wifi is now ok (was not working with panel 1.. can this be correlated ?)
Screen works better with panel 2, but I'am still not sure if mine is 2 or 3)
Keymap Fixed : was only a matter of using bash insted of default busybox's shell
camera is not working
GPRS modem not working
Battery consumption is high with system on sdcard
Stay tuned !
I am working on a couple of things, specifically a "build.prop" mod and adding a "gps.conf" file to /system/etc, which is just a list of AGPS servers and to fix some GPS issues.
The modded build.prop that I have reworked adds some dalvik cache lines and "sleep mode" lines, as our Kaisers don't have a sleep mode implemented.
Camera and GPRS can be associated with the radio rom installed. I found that on my specific device, radio 1.70.19.09 allowed GPS and data to work smoothly, but I would lose the phone after the first call and camera had just a dark green screen. 1.65.16.25 dropped GPRS but improved data speeds and allowed the phone to work as well as the camera.
YMMV but I would say wipe any trace of WM from that phone (support is ending this May) and go directly with Android via NAND install.
Hello guys
@PoXFreak
I still have some habbits on my WM (freeOTFE encryption, contacts and some other stuffs) that are still working well on WM, and I don't feel very comfortable in switching on full Android (I mean on NAND) while I'am not very used to use Android... I would have definitely preferred to have a working platform booting from sdcard before flashing the NAND, but you confirmed that some issues may be linked to the SDCARD install...
I'm stuck since the beginning of march with the GPRS modem, and I don't clearly understand what are you talking about (have to check what you mean by radio).
My problem is, at the moment, that I don't have any mean to debug : is there a way to activate logs for users spaces programs ? Where to find em ?
If there is a better way to debug, what is it ?
As always, thank you, in advance, for any answer.
I'll try by myself a soon as I can (and, during the last weeks, it was not the case).
Best regards
I will add, moreover, that I'am still not sure of my panel (2 or 3 !!!)

sd-card blues...

Hey guys I have a question for you all about sd-cards
I sbf'd
Installed ota 5.7.894 (because of no true .906 sbf I won't flash it)
Regained root
Installed busybox 1.20 (figured newer might be better)
Installed safestrap (tweaked of course 1.08f)
Now
My phone see's the internal/external sd-cards fine and mounts/formats/explores just fine
My laptop also see's internal/external sd-cards just fine
However
Rootbrowser cannot see the sd-card
Safestrap cannot find /sdcard
But
Root explorer can see the internal and external just fine
I have tried sbfing several times to see if it will fix it
I have tried not installing the ota,changing versions of busybox ect..
Why can my phone see and work with the sd-cards just fine but programs cannot?
Because safestrap cannot see the sd-card I cannot create backups..
Any help is greatly appreciated
I think Rick#2 acknowledged this in the safestrap 1.08f thread and had this advice for those experiencing the error:
(For the record, this change almost worked for me - safestrap would now access my external sdcard (/sdcard), but when I would select a zip to flash, it would just take me back to the menu. I dropped a reply with my results in that thread.)
Rick#2 said:
While you're in Safestrap, either go into the console or "adb shell" into your phone. (Remember that for adb to work properly in the recovery your phone has to boot up with the USB cable already connected).
If you type:
Code:
ls -l /dev/block | grep mmcblk0
what output does it provide? For me, it spits out "mmcblk0" but... I'm pretty sure that for those that aren't able to mount their external sdcards it will say mmcblk0p1. In which case, the fix is easy; I'll be sure to update my package, obviously, but for those of you who want to try a little DIY, copy the file /systemorig/etc/safestrap/recovery.zip onto your computer and unzip it. Inside, there's be a file called /etc/recovery.fstab; edit this and change the line corresponding to /sdcard (It ought to be on line 3, or the second line of actual text) to the following:
Code:
/sdcard vfat /dev/block/mmcblk0p1 /dev/block/mmcblk0
Click to expand...
Click to collapse
At this point, after copying the recovery.fstab back to my phone, I assumed I had to correct the permissions of the file, so I did. If I am wrong, someone please let me know!
continuing his reply...
Doesn't really matter how many spaces you have between; ideally you'll just need to hit tab each time.
Hopefully this is what the issue was. I remembered changing that line because I was getting random error messages about my external /sdcard and since I didn't see /dev/block/mmcblk0p1 in my /dev/block directory I assumed I must have made a typo and changed it... here's one tiny example of how easy it is to completely bork these things. Multiply it by a million and you have kernel development...
Click to expand...
Click to collapse
That might work if it was just safestrap having the issue..but its not
Even cwm cannot backup the apps on the sd-card as it cannot see it as well..
But root explorer and the stock file browser can see the internal/external sd-cards
And write on them just fine..and even mount/unmount and format...arrrggggg
This is killin me

[Q] encryption, ext2/4, and "filesystem too large to mount safely" error fix?

[Q] encryption, ext2/4, and "filesystem too large to mount safely" error fix?
Hello again,
With my Droid 3 (thanks to Minimoto) again working great, I've turned my attention back to encrypting some of my data on the external SD card. I had used "LUKS Manager" some time ago so that seemed the logical place to start.
Okay, the short *short* version is: What does the error message (from dmesg output) "EXT4-fs (dm-4): filesystem too large to mount safely on this system" mean and how do I fix it or work around it?
The details:
I have a 32 GB SD card with a normal ~20 GB FAT partition that Android sees and uses just fine. On my laptop I created an ext4 file system on the second partition (the remaining ~12 GB of space). Android does not see or use this, but from a terminal I *can* mount it without problems. I chose to mount /dev/block/mmcblk0p2 (external SD partition 2) at /mnt/sdcard-ext-p2. Just FYI, but I wrote a short script and put it at /etc/init.d/03mount_sdpart2 to mount this second partition at the correct mount point and it works fine. Even after a reboot the script runs without problems and now I always have my new ext4 file system present.
The reason for creating the ext4 file system is because FAT does not support files larger than 4 GB and therefore my encrypted volume cannot be larger than 4 GB *if* I create that volume on a FAT file system. With the new ext4 file system, now using the LUKS Manager app, I created a new volume at the above mount point with a size of approximately 11.25 GB. This worked fine, too. The last step, however, actually mounting this encrypted volume, keeps failing. It was supposed to be mounted at /mnt/sdcard/LUKS. Unfortunately, LUKS Manager did not produce much in the way of information about why it had failed.
A quick note about file sizes: If I use an app like "ES File Explorer" and go to /mnt/sdcard-ext-p2 where the large volume file exists, ES says the volume file has a size of -805306366 bytes, obviously wrong. Fortunately, if I use the terminal and look at the file size with "ls -l" it has the correct size. Furthermore, after I opened the volume below using lm.cryptsetup I can use its "status" command and after converting the values from sectors (each sector is 512 bytes) it also displays the correct size of the encrypted volume.
So, back to the terminal where I decided to do the steps manually and see where it failed. For the most part, I used different device and directory names than what LUKS Manager would have used, mostly to be sure I wouldn't accidentally conflict with another process/app. The 'lm.cryptsetup' binary is provided by LUKS Manager and placed in /system/bin. I have the version of busybox that, I assume, ships with Minimoto which is busybox v1.20.0. This is where the 'losetup' I am using comes from.
Concerning loopback devices: LUKS Manager defaults to using/creating high numbered loopback devices, 300 for the first volume created. On Android the loop devices are created in /dev/block, but some tools don't seem to look there. In particular, lm.cryptsetup complains about not being able to find a free loopback device and 'losetup -f' (which displays the next free/available loopback device) always refers to devices in /dev regardless of where they really are. Making symlinks such as "ln -s /dev/block/loop0 /dev/loop0" for each of the currently present loop devs (0 through 7, and 300) fixes both of these problems. That said, whatever manner LUKS Manager uses to execute the underlying tools works properly with the loop devs being located in /dev/block. This can be verified by using "lm.cryptsetup status <crypt_dev>" and the status output shows that it is correctly attached to, for example, /dev/block/loop300. Making these symlinks is more of a convenience/fix for when one is working directly on the command line.
Where, before, 'losetup -f' indicated that /dev/loop0 was free (even though it did not exist), after making the symlinks the same command indicates that /dev/loop4 is the next free loop. On my phone, at that moment in time, that was the correct answer. loop4 also makes sense because I have four apps that I have "moved to SD" and for each app that you do this one loopback device is used (so loop0 - loop3 were used by apps "moved" from main internal storage). Creating these symlinks also made lm.cryptsetup stop complaining/erroring about not being able to find a free loop dev. Finally, running "losetup" without arguments is supposed to list the used loop devs and what is using them. Before making the symlinks is produced no output, and now, after the symlinks, it displays:
Code:
/dev/loop0: 0 /mnt/secure/asec/blah_appA.asec
/dev/loop1: 0 /mnt/secure/asec/blah_appB.asec
/dev/loop2: 0 /mnt/secure/asec/blah_appC.asec
/dev/loop3: 0 /mnt/secure/asec/blah_appD.asec
/dev/loop5: 0 /ss/safestrap/rom-slot2/cache.img
/dev/loop6: 0 /ss/safestrap/rom-slot2/userdata.img
/dev/loop7: 0 /ss/safestrap/rom-slot2/system.img
As you can see, loop4 is missing/available. Also, rom-slot2 is correct as it is where I opted to install Minimoto, rom-slot1 currently containing CM 10.1.
With the loop device issues taken care of, the steps I performed are as follows:
Code:
$ su
# lm.cryptsetup luksOpen /mnt/sdcard-ext-p2/MyCrypto.vol MyCrypto
<type in passphrase>
# ls /dev/mapper
MyCrypto control
# mkdir /mnt/sdcard/luks-tst
# mount /dev/mapper/MyCrypto /mnt/sdcard/luks-tst
mount: mounting /dev/mapper/MyCrypto of /mnt/sdcard/luks-tst failed: File too large
# dmesg | tail -2
[20665.748504] EXT4-fs (dm-4): filesystem too large to mount safely on this system
[20665.750732] EXT4-fs (dm-4): filesystem too large to mount safely on this system
You can see from the above block my commands and the output, especially errors, that followed. Clearly, the file is "too large"... but how? The whole point of this extra partition and ext4 file system stuff was specifically to get around the FAT 4GB file size limitation. Unfortunately, while these errors tell me that something is too large, what *part* is too large? Is the 11.25 GB volume *container* too large, or the ext2/4 file system that exists inside the volume? And if either is too large, what is the maximum size I can make them? I did try adding "-t ext2" and "-t ext4" to the mount command, but neither one changed the outcome nor did they change the messages that were output.
The 'mount' binary (like most others) is provided by busybox, so it could possibly be part of the problem. However, the last two errors above come from the kernel log (via dmesg) which means that at least part of the issue is the kernel, maybe the file system modules. I also checked the logcat output, just in case, but it did not contain anything related or useful. Minimoto 1.7 is using kernel version 2.6.35.7 and perhaps it has some maximum size issues I am unaware of. With the exception of my Droid 3, I haven't used a 2.6.x Linux kernel in a very long time.
I've searched around here as well as the fairly small LUKS Manager message board and the Net at large, but I haven't been able to find the answers I'm looking for. Any ideas as to what I might have done wrong, or something I haven't done but should? I'm not sure how to proceed. Just to be perfectly safe, I did try rebooting but it made no difference.

Re: [Q] encryption, ext2/4, and "filesystem too large to mount safely" error fix?
Could it be that your mount point is within the FAT fs, what about creating a new mount point at say /mnt/LUKS

Re: [Q] encryption, ext2/4, and "filesystem too large to mount safely" error fix?
I tried using /mnt/LUKS (instead of the previous /mnt/sdcard/LUKS) as the mount point, but nothing changed. The "filesystem is too large..." messages still appeared.
I don't know why there are two such messages separated by about 2/1000th of a second in the dmesg output even though I issued just one command. It was the same way in my first post.
If I recall, the original reason for putting the mount point under /mnt/sdcard was so that most apps could see/use the new area without having any extra knowledge.

SMB/CIFS on tab S2?

I bought a tab S2 about a month ago to replace my HP touchpad i've had/been using since the firesale about 4 yrs ago. At the time of purchase, I discovered really quickly that lack of custom roms on the S2 at that time was to much of an issue, and I returned it.
I am however seeing an alpha of CyanogenMod for the tab S2 that's looking pretty close to usable. Given that the tab is also on sale this week, i'm very much inclined to repurchase it, however, question: Does cifs/smb mounting remote filesystems work with the tab s2 rom that was posted?
You can do that on the stock S2 with many different apps in the Play Store. ie. ES File Explorer, Solid Explorer, AndSMB

Correct me please if i'm wrong, but those applications just allow me to browse remote filesystems from the application itself. They don't smb mount them. It's the cifs.ko file i'm missing (which i'm assuming is included with cm12?)
The cifs.ko file would have to be done via a kernel module based on what I seen from other devices. I do not know if it is included in CM kernels or not.
Did you or anyone get cifs working?
I understand it may be possible to compile a cifs.ko and insmod it.
I don't know how possible that is but whilst I'm googling how to compile I thought I'd see if anyone had done it.
Cheers, Guy
I got CIFS mount working on my 710 by installing Neked_Nook_MM-710-V1 and my fork of @engine95 mm kernel which has the cifs module enabled.
Hi thanks for the reply
I don't suppose you have any tips or suggested posts/ guides I could use to recreate your setup?
I guess I could figure out how to get neked nook flashed based on the guides but the fork of the engine95 Kernel that includes cifs..? I can see a post about the permissive kernel by engine95..
Is your device fully functional and stable now?
Thanks a lot,
Guy
Neked nook is very stable. My tab s2 has not crashed so far with that rom, and my custom kernel. I have attached my boot image. This is a fork of engine95 kernel with just cifs module added. This kernel only works on MM.
Extract boot.zip and flash boot.img via twrp(boot image) or fastboot.
You can use the attached cifs manager to mount your smb/cifs drives on android as a directory.
I am only able to mount it to /mnt/drive. I could not get it to mount to /sdcard.
Awesome thanks
I use cifsmanager on a Chuwi hi12 that i've rooted, it already has the cifs modules and permissive kernel so I am able to mount the shares almost wherever I like - and I use cifsmanager to poke 1TB of satellite images into the map folder of my mapping app on the SD card. But I don't know if cifs was in the kernel (chuwi is on lollipop) already or part of the rooting process, would love to recreate the setup on my samsung as its a far superior device.
I'll give it a go this weekend, really appreciate you taking the time to upload the files you used.
Cheers,
Guy
Hi Currowth,
I know life is too short to help each noob, but can I trouble you for another pointer?
I used the full image of Neked Nook MM v1, and the boot image you provided, and the tablet is working great, and if I cat /proc/filesystems I can now see cifs listed....but..
I can't mount any cifs shares - to anywhere, including /mnt/drive. I get the mount failed Mount: I/O error.
(I think my process was along the lines of: ODIN to cf-autoroot (i'd actually done this a while before starting this thread so including in case its relevant, as i dont know if there is an issue with a /system or systemless root?) then I ODIN'd TWRP on, took a full backup with TWRP and then wiped data,cache, system etc and flashed Neked Nook on, booted into NNook, then went back to twrp and put the boot image you provided on.
Any help greatly appreciated.
If it means anything I'm not trying to watch Batman in bed, I'm trying to put together a repeatable solution for me and my overland traveller friends so we can take huge amounts of map and satellite image tiles completely offline when we're driving our landrovers, toyotas etc across deserts where sat navs or road maps are useless.
thanks again,
Guy
*Edited to add i've been googling the crap out of the mount i/o error, tried a patched version of cifsmanager, tried copying the apk to the system/apps folder and changing its permissions before reinstalling.. no joy
Looks like it can be a root issue. This is what i flashed to get root. "BETA-SuperSU-v2.74-2-20160519174328"
try to install busybox also and try again.
If that does not work:
Can you try to run this in adb shell as root?
mount -t cifs -o username="username",password="password" //smbpath/dir mnt/cifs/dir
replace "username,"password", and smbpath/dir

Thanks for coming back Currowth,
Ok my SuperSU from the original cf-autoroot was 2.46. I assumed I needed to remove that so I ran the unroot function and then used twrp to flash the version you linked to, after reboot SuperSu is at 2.74.
Unfortunately i have the same I/O error.
I also ran adb root from my win10 machine and tried the manual mount command as you suggested - it returns I/O error also. Initially it said 'no such file or directory' so I manually created the dir, with the name the same as the share dir, in /mnt/cifs.
command output
255|[email protected]:/ # mount -t cifs -o username=admin,password=admin //10.10.10.254/Public1 /mnt/cifs/Public1
mount: No such file or directory
255|[email protected]:/ # cd /mnt/cifs
[email protected]:/mnt/cifs # mkdir Public1
255|[email protected]:/ # mount -t cifs -o username=admin,password=admin //10.10.10.254/Public1 /mnt/cifs/Public1
mount: I/O error
One other thing, in the NNook image thread, i see it says make sure you 'ODIN M' first. I'm embarrassed to say i don't know what that means!
update in mean time: i started again, based on doing all the flashing whilst rooted with the older supersu. So i've unrooted, rooted with your beta_xx linked above, wiped system, cache, data and dalvik, flashed the Neked Nook full MM V1 ROM, booted into that, then back to twrp to flash the boot.img you linked above, installed busybox, the linked cifsmanager, tried to mount, then updated supersu as recommended in NNook thread, rebooted and tried mount again but no joy, always getting i/o error.
just for further info, the shared folder does work on my chuwi with cifsmanager, so hopefully that is not the issue. Before I re-did the ROM and the boot image, i installed paragon ntfs and was able to successfully mount an NTFS formatted SD card into the /mnt/cifs/public1 directory.
interestingly cifsmanager couldn't create the directories under /mnt, but i was able to create them manually and then get an IO error. I changed permissions on the /mnt/cifs folder and now it can create the directory when attempting to mount but still gets IO error.
i'm beyond my depth, guess it feels like cifsmanager is either not working or not got permission - or something i've done prior to the NN and kernel flashes has caused an issue.
Its starting to feel like a lost cause. You know better than me - if this is the end of the easy flash-type fixes to try, perhaps I should just throw in the towel.
Thanks again for your help Currowth, you're a gent
I just did a clean install to replicate you issue, but was not able to reproduce it. 'ODIN M' means that install a marshmallow rom first via ODIN. If you already came from a marshmallow ROM, you can ignore it.
The steps i took to ensure that i am was able to get cifs were the following:
First i installed "Neked_Nook_MM-710-V1.zip"
Next I installed "BETA-SuperSU-v2.74-2-20160519174328.zip"
Last i installed "boot.img"
I did this all through twrp.
Reboot, dont setup knox if it asks you to.
Try to do a wipe, then reinstall the following and try again.

Thanks for coming back Currowth,
Ok my SuperSU from the original cf-autoroot was 2.46. I assumed I needed to remove that so I ran the unroot function and then used twrp to flash the version you linked to, after reboot SuperSu is at 2.74.
Unfortunately i have the same I/O error.
I also ran adb root from my win10 machine and tried the manual mount command as you suggested - it returns I/O error also. Initially it said 'no such file or directory' so I manually created the dir, with the name the same as the share dir, in /mnt/cifs.
command output
255|[email protected]:/ # mount -t cifs -o username=admin,password=admin //10.10.10.254/Public1 /mnt/cifs/Public1
mount: No such file or directory
255|[email protected]:/ # cd /mnt/cifs
[email protected]:/mnt/cifs # mkdir Public1
255|[email protected]:/ # mount -t cifs -o username=admin,password=admin //10.10.10.254/Public1 /mnt/cifs/Public1
mount: I/O error
One other thing, in the NNook image thread, i see it says make sure you 'ODIN M' first. I'm embarrassed to say i don't know what that means!
update in mean time: i started again, based on doing all the flashing whilst rooted with the older supersu. So i've unrooted, rooted with your beta_xx linked above, wiped system, cache, data and dalvik, flashed the Neked Nook full MM V1 ROM, booted into that, then back to twrp to flash the boot.img you linked above, installed busybox, the linked cifsmanager, tried to mount, then updated supersu as recommended in NNook thread, rebooted and tried mount again but no joy, always getting i/o error.
just for further info, the shared folder does work on my chuwi with cifsmanager, so hopefully that is not the issue. Before I re-did the ROM and the boot image, i installed paragon ntfs and was able to successfully mount an NTFS formatted SD card into the /mnt/cifs/public1 directory.
interestingly cifsmanager couldn't create the directories under /mnt, but i was able to create them manually and then get an IO error. I changed permissions on the /mnt/cifs folder and now it can create the directory when attempting to mount but still gets IO error.
i'm beyond my depth, guess it feels like cifsmanager is either not working or not got permission - or something i've done prior to the NN and kernel flashes has caused an issue.
Its starting to feel like a lost cause. You know better than me - if this is the end of the easy flash-type fixes to try, perhaps I should just throw in the towel.
Thanks again for your help Currowth, you're a gent

Thanks Currowth I will try and give it a go tomorrow
Just a thought, are you booting into Android after each step, or doing all the flashing in one twrp session then doing first boot once all items are flashed?
I flashed them in one session without rebooting.
Hi Currowth, I've had a breakthrough!
I re did the NNook/root/boot image in the order you advised.
I have been using a patriot node WiFi disk enclosure, that works with cifs manager on my other tablet. Today I was working away from the WiFi disk so I made do with a windows pc to provide a shared folder. After setting cifs manager up I was able to mount the share under /mnt, but not to any other location. I got back to my WiFi disk, and that continued to give an io error!? So windows worked but the patriot didn't. Weird. I'd ruled the patriot out as it works on my 5.1 lollipop tab.
So I continued to mess around... I had stumbled across another app called mount manager by Ryan conrad (I don't have the link but I have the apk) which has more noob-friendly options and found if I used the ntlmv2 option I could mount the patriot into /mnt !
I did try to get it to mount to other locations and although it succeeded in the app, the mounted folder was empty.
As my app - Osmand+ has the option to manually specify it data folders I created a 777 permission folder for it under /mnt, and then mounted the patriot containing my satellite images into the appropriate empty tile folder.
Working solution!!! If a little messy.
Thanks so much for your help, the Samsung s2 is about 400% faster and more practical than the other tablet so really happy
I don't know why android devices are so limited by manufacturers when the OS is capable of so much, but that's a different conversation haha
A follow up on this in case it is useful to others...
Using /mnt was a bad idea. /mnt is mounted / built on a system partition as a mount point for other file systems or devices (how I have explained it to myself). So anything you add here as a folder gets destroyed when you reboot.
So, I installed my osmand app to /data/osmand and then used a root terminal to run "chmod -R 777 /data/osmand/" to set permissions to 777 on that folder and all subfolders.
After doing this I was able to get mount manager to mount my cifs share into an empty subfolder in the apps folder tree.
I initially tried changing permissions on /data in case it was needed for folders further down the tree, but it was not needed - which is just as well because again, /data is mounted at boot with 771 permissions, so changes 777 back to 771 after reboot. To change that would involve unpacking the boot image in order to edit the init.rc file and then repacking. I didn't bother it was not required.
If anyone wants mount manager, Google 'ryan conrad mount manager' and take your chance with the apk sites, can't remember whigh site I used!
