Flash the stock firmware via ODIN
To root your device:
Flash PhilZ CWM (custom recovery) via ODIN
Flash SuperSU via PhilZ CWM

flash stock firmware via ODIN,
and also cmw file ie a tar file via ODIN.
use unlockroot.com and download the software to root or a cwm flashable superuser zip file.

[Q] about mobile odin pro

hello
I used mobile odin pro to update my galaxy note 10.1.
the update to the latest germany firmware CM8 was successful.
but i didn't get root access
I only clicked everroot option and installed supersu after the boot
supersu cannot update the binaries (no root ??)
what can i do ?
thank you :fingers-crossed:
ps: sorry for my poor english
Install CWM from the developement thread. It will root and install CWM. If you don't want CWM then install & run triangle-away and flash the stock recovery back on.

sch-i535 4.4.2 cant flash custom recovery (both TWRP/CWM) why?

Hi Experts,
I have some experience on flashing phones and custom roms but in this case i'm lost.
Can't find a way to install CWM or TWRP, i have tried flashing with Odin and also tried to install via the CWM/TWRP app.
After flashing recovery with CWM/TWRP app the phone becomes bricked and i get a Verizon message "secure fail: kernel system software is not authorized by verizon..."
If i try to flash recovery with Odin in download mode it will result in an error: FAIL! (Auth)
And from the stock recovery i cant flash as well which make sense.
* Phone is 4.2.2
* Root was made with towelroot.apk > manual install of SU and confirmed with root checker (Other root methods did not worked for me).
Please help!

Simple, your bootloader is locked. 4.4.2 can be rooted but that's it. You can run a safestrap recovery & flash TW ROMs only.
?Oct-M d2att KrAkEn Kernel?
I had used safestrap, Cant flash... because it said cant mount system...

Thanks Canodroid15, Can you refer me to a "How To" ?
Is there anyway to install CM 12/13 on the sch-i535?

I had the same problem. My s6310N had S6310NXXAMK1 and I couldn't install CWM or TWRP. Then I just downloaded S6310NXXAMD1 firmware from Sammobile (LINK) and installed it with ODIN. Then I was able to install CWM.

If have already installed old twrp and want to install a newer version you can install it by this zip file using the old recovery then reboot
And if you want to install it for the first time you must use odin
The newest version is now available for Galaxy j7

Sorry you have to go back to stock firmware an start again ! caming from stock firmware you have to go into stock recovery an do a factory reset before installing twrp ! An in odin you have to unclick auto reboot in options an pull battery an boot rite into twrp an flash supersSU then reboot system !
OK here is a link for the firmware you are going to need the AP,BL,CP,an the CSC . files from the link !

This is the step that I messed up on thanks so much. Only thing is that I can't download the 2 Gb ap file at the moment, do you have a link to the original recovery img?
