jffs partition is read-only and cannot format-restore

[FourthandShort]

You made a post here about flashing 388.7 which cleared up the JFFS error(s):

Yea none of this is working now. Have tried the factory hard reset, WPS, reset through GUI with initialize everything checked. Nothing is working.

I think the last resort is to try the firmware restoration tool. Everytime i try and flash any firmware, its giving me the firmware upgrade is unsuccessful error. My RT66 ended up as a paperweight, my RT86 did the same, looking like I may be batting 3 for 3 on these.

No warranty on this one?

This would be the first one where I had any warranty. The other two died right after the warranty period. Going to try and chat Asus to get an RMA, the firmware restoration isnt even working.

I was able to solve the problem using all the suggestions provided here plus some additional linux tool/knowledge from the forums.
So I explained befere my problem was that I could not umount /jffs due to resource device busy and then the same applies for ubirmvol vol id of jffs. Lsof was essentially useless but fuser -m /jffs pointed me towards both syslog and asd.
While getting rid of syslog was not a problem , the asd was a different story.The process kept restarting after every kill keepin a lock to /jffs. I found below tips within another thread about killing asd :

touch /tmp/killasd && killall asd && mount --bind /tmp/killasd /usr/bin/asd

Once asd was finnaly gone umount and ubirmvol did not produce anny errors and I was able to recreate jffs using the steps described in previous posts.
Hope it helps.

Hey can you provide step by step, on how to unlock the jffs?

Sure, I can try. Just remember that it may be slightly different for many users due to different processes running in the background. Additionally, such actions may brick your router if something goes terribly wrong.
You've been warned. I also assume this is the jffs read only issue. Credits to below posts from this forum:

jffs partition is read-only and cannot format-restore

Interesting - the mtd drivers says ok, the ubi volume manager says ok. Hopefully it is just a filesystem issue - might be able to recover at that level. Just wondering - have you tried different factory resets - like the hold WPS button or press reset for a long time? I am surprised (like you!)...

It has never been resolved. I didn't know the issue goes so far back. And I'm sure you have tried everything suggested in the previous thread. :(

1. Disable usage of jffs scripts within web gui.

2. ssh onto the box

3. Execute

umount /jffs

If above cmd returns no error proceed to point no. 4.

3a. If umount /jffs returns an error with devise/resource busy, then it means some process is still holding some lock to the /jjfs file. We need to find out what it is and kill it.
Execute

fuser -m /jffs

3b. It should return something like below:

admin@GT-AX6000-6E78:/tmp/home/root# fuser -m /jffs/
1452 2396

Identify running processes using ps and numbers from previous command. Like below:

admin@GT-AX6000-6E78:/tmp/home/root# ps | grep 1452
 1452 admin     3328 S    /sbin/syslogd -m 0 -S -O /jffs/syslog.log -s 512 -l 7

admin@GT-AX6000-6E78:/tmp/home/root# ps | grep 2396
 2396 admin    12140 S    asd

3c. Kill those processes you have identified in the previous steps

killall syslogd
touch /tmp/killasd && killall asd && mount --bind /tmp/killasd /usr/bin/asd

####Different processes may pop up here, but the general rule remains the same - we need to get rid of those to proceed. asd kill option found below

What is "asd" process?

It actually has no reason to scan the hdd, since no execute permissions should be allowed there. Asus got it wrong with security to begin with and is now patching it up in a stupid way. It might help to write a script that constantly checks and kills the process, although it seems like rc...

thank you, looks like my jffs router volume is either missing or corrupt, so im returning my router just now.
