Permission denied when trying to root, how to fix this

I'm trying to root my tablet once again after I accidently unrooted it. I done tried three diffrent rooting methods: "SparkyRoot" "debugfs" and "Primetime" and all came unsuccessful. I keep getting a message in the command prompt saying access denied when it try to copy files to root it.
It look like this:
Found system partition at: /dev/block/mmcblk0p1
Step 1- pushing files...
failed to copy ' debugfs' to ' /data/local//debugfs'ermission denied
failed to copy' su' to /data/local//su': Permission denied
failed to copy' debugfsinput' to '/data/ local// debugfsinput': Permission denied
failed on '/date/ local/tmp'- Permission denied
^^^^I get that everytime.....what could be the problem, how do I fix it. Before you ask YES android debugging is enable and YES Unknown Sources is enable. So please tell me what I need to do to fix this problem.
You have to be able to obtain root permissions to mount the file system with RW so you can move/copy files to then get root all the time.
The permission denied is because you arent root and/or havent remounted teh filesystem read write (possibly because you can't get the access you need) and this the file move/copies fail.
How do you root? Good question. One I have been struggling with for days.
I have the same issue with my infinity
TF201 Root Fix
I was having the same problem when trying to regain root access after update to JB from ICS. Try Urkel's Fresh Root or Urkel's Fresh Start, see the thread on this site.

vendor.prop incrementals (help pls)

Once I copy the vendor.prop out and change the incrementals I can put it back? aka wont copy paste says read only ive tried changing permissions but it just keeps saying read only any ideas?
you need a file explorer with root rights,eg root explorer
just open and edit it,copy out is not nessary

I recommend making a backup copy of the file before editing it.

Unable to edit vold.fstab

Hey guys so Im trying to edit my vold.fstab file to switch my emmc and sdcard interfaces around but everytime I try and edit the file it is denied due to permissions, if I try and set the permissions to 66 (rw-rw-rw) it gets denied and I get an error saying certain filesystems protect these types of files.

Permission denied when trying to copy file to system/bin in Ros3.0

While trying to get touchscreen to work in my wacom pen/touch enabled laptop I was trying to copy a file called "inputattach" into the system/bin folder (as per post #6 in this thread ) of Remix OS 3.0 but I am always getting permission denied error. This version of remix OS comes pre-rooted (root checker says it is at least) and root seems to work fine except for changing any permissions inside the system folder or the permissions of the folder itself. I tried several root browsers but nothing worked. I'm a noob, plz halp?
anyone?
