FEWER CHANCES OF ERROR :laugh:

UPDATED 2016-08-09 TO INCLUDE 32 BIT DIRECTIONS MANY THANKS TO [MENTION=5369004]ireMaN[/MENTION] FOR INPUT

THIS IS MODIFIED NOW FOR BOTH 32 AND 64 BIT!

THIS IS ALSO ONLY FOR HDD INSTALLATIONS

Fellow Remixers:

As many have found out, version 3 of RemixOS doesn't allow changes to the system. This is because instead of a system.img it now uses a system.sfs. For most of us there is no advantage to this, and it makes it impossible to perform even simple mods to the build.prop.

So we must convert that pesky system.sfs to a system.img and substitute a modified initrd.img.

There has been so much interest in this that I have tried to write a guide. I hope it is accurate, but I encourage feedback to improve it. EDIT 2016-08-03: WORKS FOR 3.0.102 ALSO

EDIT: 2016-08-09 WORKS FOR 3.0.103 ALSO

Here it goes:

ALL OF THIS IS DONE FROM WINDOWS. From File Explorer, navigate to your partition with RemixOS folder. Note the drive letter; mine was d:

1 Open the RemixOS folder on that drive; you should see a system.sfs file.

2 First you need to download the correct (32 or 64) modified initrd.img from here:

https://drive.google.com/folderview?id=0B3gcDbDvV4MkTm5raUZRZXl4NkE

3 Use File Explorer to navigate to the Downloads folder; you should see a file named initrd_(32 or 64)_rw_3.0.101.img

4 Copy that file into the RemixOS folder on the drive where you installed Remix.

5 Open the RemixOS folder; you should see both the original initrd.img and the new initrd_(32 or 64)_rw_3.0.101.img

6 Rename the initrd.img to oldinitrd.img to save it in case you need it

7 Rename the initrd_(32 or 64)_rw_3.0.101.img to initrd.img

8 Next convert that system.sfs file to a system.img file

9 Using your web browser, download and install RMXTools from http://xdaforums.com/remix/remix-os/rmxtools-remix-os-data-img-t3308158

10 Then in File Explorer, navigate to Downloads folder and extract the RMXTools zip. (EDIT: You may need 7zip to extract it)

11 Then navigate to the newly created RMXTools folder and navigate to the bin64 folder

12 Open a command window by using shift&right mouse button and selecting the Open command window here

13 Assuming that your RemixOS folder is on drive c: type unsquashfs.exe -d c:\temp c:\RemixOS\system.sfs

If your drive letter is e: for example, you would substitute e: for c: (EDIT: Do not change the -d as it is part of the command)

You should see it writing blocks for a few seconds

This should create a new system.img file on drive d: in folder temp

14 Now you need to navigate again to the drive with the RemixOS folder. You should see your newly created system.img in the temp folder

15 Copy it into the RemixOS folder

16 Now open the RemixOS folder; you should see your new system.img alongside the original system.sfs.

17 Rename the system.sfs to oldsystem.sfs to keep it in case you need it again

OK now time to reboot into Remix

You should now have writable system

Hope this helps

If it works for you please hit the "thanks" and if you're REALLY happy then I can always use coffee money :o

NOTE: TO TAKE OTA UPDATE YOU NEED TO DO THE Following FROM WINDOWS:

A In File Explorer, navigate to the RemixOS folder

B Find and rename the initrd.img to initrd_(32 or 64)_rw_3.0.101.img depending on your version

C Find and delete system.img

D Rename oldsystem.sfs to system.sfs

E Reboot ti RemixOS and download the update and select the Reboot option.

F After the OTA is installed and you are at the desktop you need to repeat steps 6 through 17 above
