LG Urbane (w150) "/" file-system stuck in "read-only" - LG Watch Urbane

I have a LG Watch Urbane model W150 (original model) that I have rooted on several occasions using Visual's M1D63X firmware build.
Maybe a month ago while trying to edit a file on the watch using ADB Shell, I found the "/" file-system locked as read-only. I could re-mount the / file-system as RW and make the changes as needed but on every reboot it returns to read-only (RO). I understand that this happens sometimes in Linux if a problem is detected in the file-system to prevent further damage to files and file-system. The thing is, I have done full WIPE through TWRP, checking every box to make sure the watch was completely wiped, then I re-installed stock M1D63X firmware again. It is still locking the "/" file-system.
The side-effect to the locked file-system is that although apps such as Watchmaker can install, their settings do not save properly. My preferred watchface in Watchmaker used to return after reboot but now it reverts to the main stock watchface included with Watchmaker whenever rebooted. Similar issues occurred while rooted, in apps such as Kernel Audiutor which forgot that I had turned off two of the four cpu cores.
Does anyone know how to fix a Linux "file-system error" read-only lock or at least a way to set the Urbane to run a single line script to remount the file-system upon boot. Obviously, the command below will remount the system as RW (when rooted) but it needs to run on every reboot.
mount -o rw,remount /​

Disregard this thread - Moderator, please lock or delete
Either I was wrong about my filesystem being locked or I managed to fix it. I had been testing whether the filesystem was still locked by attempting to create a file using the following command.
touch /temp.txt
It didn't occur to me that "/" is read-only by default. After I did a full upgrade to AW 2.0 then back down to stock MD163X before returning to the mod, the issue from the original post was apparently fixed and apps could once again save their configurations properly. I just tested for the RO condition using the wrong folder. When I tried the same test to create a file to a subfolder it worked properly.

Empty SMS Draft (Not really)!!!

Hi, i got a problem, my SMS Draft Folder says that I have 1 draft SMS, but when I open the folder, its empty.
How can I erase this notification on SMS Drafts Folder?
Thanks for your Help.
Does it contain your signature ?
Otherwise, you could have a filesystem corruption. Run fsck on /data from recovery.
Offtopic: I recently had a filesystem corruption on /system. Trying to write to /system always ended in phone reboot; creating empty files was fine; filling the file failed. Used to work; so I felt like it was not a rooting issue. Took me a few hours to be able to get the proper fsck installed; in the end, my guess was good. Fsck found several errors. => rooting a phone is risky; messing too much in /system CAN produce errors; and Android never runs fsck on /system => this issue must be fixed MANUALLY. Did not dig init scripts, but I think it should fsck /data at boot.

[Q] Droid3 system corrupt and unable to fix

Okay, so this is a doozy. I recently got a Droid3 to replace my original Droid. I've had it for less than 3 months. Its been rooted using Pete's One Click Root for this entire time without any issues.
Last week the following symptoms manifested:
1) Most applications, including system applications, force close constantly.
2) I'm usually unable to run any applications, including the Market.
3) What applications are having issues is not consistent.
4) The phone will reboot itself randomly, sometimes constantly.
5) Sometimes after a reboot it gives me no service and has the "Touch Android to begin" screen again. The phone is completely unusable when it does this, and the only fix is to pull the battery and then its back to its previous state.
5) Any changes made to the phone do not survive a reboot.
This last one is the real kicker. I can go through, uninstall every application I've ever downloaded but if you restart the phone or it restarts itself they will all return. This goes for everything on my Internal Storage. The SDCard seems unaffected...
I tried the SBF trick here from rootzwiki. (can't link since I'm new)
This did not work. How it failed might be important:
1) The primary method (psouza4's) acts like its successful but doesn't actually do anything.
2) RSDLite method will fail in step 3 (mbmloader.bin) every time, no matter what fastboot file I try to use.
3) After doing RSDLite I had the "flashboot flash failed" error and the phone was unusable. I then tried psouza4's method again and my phone has reverted to the same broken state it was in when I started.
So I'm not at all sure what I can do here. Since the bootloader isn't cracked yet I have no means to load another ROM. The only method I can find for Droid3 is through a Marketplace app that, on the rare instances I can install it, force closes immediately!
Any advice or ideas at all would be nice.
As for what started this, only two things happened out of the normal phone usage:
1) My girlfriend tried to text me a picture for the first time (of some chairs she wanted to buy for those curious/suggestive ) which never got to me initially but when it finally did after the 4th attempt I was never able to download the image.
2) I put a PDF file on the Internal Storage. Its one I've had for years and its just some manual I needed mobile and I don't have a laptop. Confirmed its malware free as far as any software can tell.
Working theory is I unplugged my phone from the USB too quickly after uploading the file but I don't know for sure. Nothing else was done unless Verizon had a OTA update that would break a rooted phone (guessing not since no one else seems to have this issue anywhere).
Again, any help someone can provide would be excellent. I'm going to have to load up my broken Droid in the mean time. Keyboard doesn't work and the touchscreen is failing but it can take calls more reliably than my Droid3 currently!

I can say a couple words to describe my reaction.. OH ****. Your phone seems to have too many problems to be software related. Try to flash back to stock 5.6.890 and get a new phone.
Sent from my DROID3 using XDA App
Hmm, I guess for the mean time I'll just have to keep trying to get the Marketplace ROM Manager to install and launch. Should be a way to install straight to the SDCard that doesn't have problems.
Thinking it over, my Internal Storage may just have a bad sector... Yeesh.
Have you tried formatting /system in mounts and storage in CWM? Then reinstalling a fresh rom on top?
Sent from my DROID3 using xda premium
Negative. I didn't have CWM installed (stock ROM just rooted for certain apps) and apps are usually crashing now.
I'll give that a shot though. Sometimes I can use an app so maybe if I'm persistent...
and to verify, you are using the verizon droid 3 xt862? Are you on 5.5.959 or 5.6.890 (or possibly 5.7.894)?
Yea can't get any new apps to run. Interestingly, the camera app seems to crash the OS at the moment.
I think I'm going to have to try to RMA...

Its running 5.6.890. Unless I'm mistaken its the xt862. I've only had it since September.
well as long as root isnt showing and the /system hasnt been changed from stock rom, it should work. i do find it bad that rsd didnt work. i wonder if you were trying to flash the .959 sbf on your .890 system? I would def try again to sbf and wipe data/cache through stock recovery after that using volume buttons (android!)
Well, that's kind of the problem. Changes don't survive a reboot so i haven't been able to unroot the phone. I double checked and the file was the .890 flashboot. Wiping data/cache literally does nothing.
Is there a way to format this offline, from a PC? Going to try some more Google searches...
wiping data/cache should erase all of your saved data and force you to *228. Make sure USB debugging is on, set usb to Charge Only, try petes motorola tools to unroot but using RSD 5.5 fastboot .890 found http://forum.xda-developers.com/showthread.php?t=1255198

1) How do you unroot with Pete's motorola tools? Is it a different version than the one click root? Cause that's how I rooted my phone in the first place but it doesn't seem to have an option to unroot...
2) The link for the flashboot file gives a 404 error. The attached .RAR only has the .XML file.
Any place else I can get that version?
just enter stock recovery by holding down the x key on the keyboard when you boot up and wipe data

If you read the original post, that doesn't work.
Okay so I had an outdated version of Pete's tools which is why I didn't see the unroot option. Mine is the older one that was a batch file, not a application.
Got that sorted out and it still doesn't work. Seems I may have some permissions issues:
Code:
> su
> /system/xbin/su
> mount -o remount,rw /dev/block/mtdblock3 /system
> if [ -e /data/local/12m.bak ];

> then

(success)
That's part of the ADB log. There are a lot of other permission denied messages, which is a little comforting. The only thing I could think of that happened is permissions didn't get set right when Internal Storage was unmounted from my PC.
Since I can use ADB to access the shell, how can I format /system on the droid3? I can't seem to find the correct root name to use.

Have you tried to root manually? Here are the original instructions vulnfactory.org/blog/2011/08/25/rooting-the-droid-3/
[edit] I guess I miss read that you are trying to unroot.
try http://rootzwiki.com/topic/4370-sbf-droid-3-fastboot-files-55959-and-56890/ but you cant go from .890 back to .959! no idea about mounting, sorry.

That's the reference to Rootzwiki I made in the original post, doesn't work sorry.
Using ADB I mounted /system as rw and tried to manually remove certain apps. Once I re-mounted they were there again. So something is preventing me from making real changes to the Internal Storage.

You don't have superuser permissions.. In the ADB shell your command line should start with a # indicating superuser permissions.. you have a $

Where do you get that idea?
When I do this manually:
1) I'm running the command prompt as Administrator
2)I'm launching into adb using the command "adb shell".
3) First thing I do is type in "su"
4) second thing I do is approve "unknown" in the superuser app on account of it never remembering I already did that.
5) I use the command "mount -o rw,remount -t yaffs2 /dev/block/mtdblock4 /system"
6) I use the "ls" command on /system/app and find an .apk to uninstall (not all my apps seem to be installed in this location either...)
7) I use the "pm list packages" command to find the rest of the files for that .apk
8) I use "rm <filename>.apk" followed by "pm uninstall <whatever that developer chose to name things>" command to fully uninstall.
I should note on my phone at this point it disappear from the application list.
9) I use the command "mount -o ro,remount -t yaffs2 /dev/block/mtdblock4 /system"
10) I use the "ls" command on /system/app to confirm and voila, the apk file is back!
The app doesn't show up in my app manager until I reboot the phone. Changes to /system and /data are not persisting and I have no idea why.
I can't seem to unmount them either so I can't format via ADB...

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

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

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 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!

AT&T XT1097 Absolutely Refuses To Mount /system Read-Write Under Any Circumstances

AT&T XT1097 Absolutely Refuses To Mount /system Read-Write Under Any Circumstances
Yes, I'm rooted (specifically using KingRoot - it's not a permanent root, but at the moment it works)
Yes, I double checked, su works.
No, SELinux was not in Enforcing mode. (getenforce returned "Permissive")
No, I can't just flash a custom recovery, my bootloader's locked.
The problem is every time I try to run a mount command - any mount command - to mount /system read-write, I get the error "Read Only File System". This is reproducible in both adb shell and the terminal emulator on the Play Store. The main reason I want to root is to get rid of all of the reinventions of the wheel AT&T put in my system partition (for instance, I have the standard Contacts app and an "AT&T Address Book"), and install busybox. I want a solution to remount /system read-write, I don't give a damn about potential consequences at the moment.
I consider myself a relatively advanced user in theory, so you probably don't need to dumb down your answer. If I don't know something, I'll ask.
What is the exact syntax of the mount command you're running to attempt to remount /system in read/write mode?

Read-only file system - ONLY SOMETIMES - On Android 5.1.1 Flash Drive

I am really stumped here. I have an Android 5.1.1 TV computer, rooted, SuperSU, shared mount namespaces, and generally working as expected. I have Tasker run a shell script, using root, to perform a nightly backup of my /sdcard to a file on a flash drive attached to one of the computer's USB ports. Seems like this should not be a problem. Indeed, at one time this worked but for some reason it started failing a few weeks back and I am trying to ascertain why and how to fix it.
In normal operations, I can access the drive at /storage/udisk0 with a file manager app or with a terminal app. I can read/write without troubles. I don't even require su to be run first.
However, when the backup script runs (confirmed as root using the whoami command), any write access to the flash drive fails reporting a read-only file system. Again, if I try the file manager or terminal apps to write immediately after the backup routine has failed, I have no problems.
I have gone so far as to place mount -o rw,remount /storage/udisk0 in the backup script (again running as root) prior to trying to access the flash drive. Still it fails. I cannot even echo hello > /storage/udisk0/test.txt from inside the script. Of course, this works fine outside of the script.
So I am stuck. I have no idea why this is occurring or how to fix things. I have tried using Chainfire's StickMount app which mounts the flash drive under /sdcard/usbStorage/sda1 and there seems to be no problem in accessing the drive that way. But that was just a test and I would really rather not go that route since things previously worked just fine without.
Any tips/hints/suggestions are appreciated. Thanks!
Edit - please ignore this as I discovered that I was somehow shooting myself in the foot. Seems that somehow a Tasker task was unmounting the usb flash drive in certain circumstances. Why this reported as a "read only" I am not sure. Cheers!
