[Guide] How to have write protection disabled on boot with stock rom - AT&T HTC One (M8)

For this to work you will need to be rooted with twrp installed.
This is for people who are on the stock rom or a rom without init.d support.
1. Download the wp_mod.ko file from @flar2's thread http://forum.xda-developers.com/showthread.php?t=2701816
and copy it over to your SD card (either internal or external)
2. Boot into twrp
3. Select the "Mount" option on the main menu and tick system
4. Go back to the main menu and then go into the "Advanced" option. There will be a "File Manager" option
5. Navigate to the folder you saved the .ko file in and copy it (just touch the file and it will bring up the menu)
6. now navigate to /system/lib/modules and copy the file there by hitting the "select" button on the bottom right.
7. Navigate to /system/lib/modules and insure the file is there. Now touch it to bring up the menu. select "Chmod" option and enter in 644
8. reboot the device
9. Once booted fully open up Terminal emulator and type:
su
insmod /system/lib/modules/wp_mod.ko
10. Once that's done open up a file manager app with root access and mount as r/w and navigate to /system/etc and look for the file install-recovery.sh
11. edit the file using a text editor, adding the line insmod /system/lib/modules/wp_mod.ko towards the bottom of the file
12. reboot and enjoy r/w on boot without running the command every time
13. profit

is this like being s-off, without being actually s-off

---

Not entirely, you will be able to make changes to system files while booted but you won't be able to flash fastboot zips like s-off

---

Or you could flash this kernel.... http://forum.xda-developers.com/showthread.php?t=2705074
And yes it does work on stock

that will only work to repair writing to SD CARD. This fix is for writing to the system.
Personally... If you can get s off.. I would do so. Makes life easier in the long run.

HI, I have an HTC One m8 developer edition
Phone details and software levels.
Model HTC One M8
Android 4.4.2
HTC sense 6.0
Software 1.54.1540.9
HTC SDK API level 6.17
I have being trying to set the r/w on system but with no success. I have followed instructions in several items in XDA and none of these have worked. I tried your method, but when finally I reboot and run root explorer I still see the folders mounted as r/o..
the .ko file is in the correct directory and install-recovery.sh is correctly modified.
Any help/assistance would be appreciated.

First off, please don't quote the whole top post when its a long guide like this. I know its the default to quote the post when you reply. So just delete it, before you submit your post. We don't need the thread cluttered up with multiple reposts of what is already in the top post.
The mod makes very specific changes to the kernel, so I would say there is most likely no way in heck this will work on an M7, and might even damage it.

HTC M8 and rw fix
Still unable to get this to work,I followed your detailed instructions and wp_mod.ko is in correct directory with correct permission and install-recovery.sh is modified correctly.
However after final rebott (several in fact) /system is still r/o
I took a TRWP backup before I started so I restored and followed your instructions again , still same result, should this work immediately or will it take several reboots before it is operative? Other discussions on this and other sites indicate the latter.

Whichever Sense file corresponds to your Android build in Settings>About>Software.
If you are on the stock ROM, I'm guessing 4.4.2, since I do not believe 4.4.3 has rolled out to T-Mobile yet.
As usual, I would make a nandroid before flashing anything.
