So basically I closely followed this guide in order to get CWM Recovery Advanced installed on this Note. But every time I try Odin fails again and again ( it says "<ID:0/007> Complete(Write) operation failed. <OSM> All threads completed. (succeed 0 / failed 1)" ).
I tried everything, restarting again and again (and again...) trying different USB ports, different USB cables different versions of Odin, different custom recovery files, restarting PC, restarting Odin, not restarting Odin... but unfortunately nothing worked yet..
As this is genuinely frustrating, I would really appreciate any help in this, so thanks in advance.
UPDATE: So I decided to maybe try a different approach. I download the Android 4.1.2 Samsung stock ROM (I forgot to mention before it was on Android 2.3.6) and installed it using Odin... surprisingly this time Odin DID work. However, when I retried installing the custom recovery Odin again failed. Indeed Odin hates me.
UPDATE 2: Finally I was able to install a custom recovery! The file PhilZ-cwm6-XXLT9-ORA-5.08.5.tar.md5 from here worked in Odin. So I then tried to installed the new version of CWM Recovery Advanced through the custom recovery that did install in Odin, but well it failed again.. I think something might be wrong with that custom recovery, I'll try a different one. Anyway I can say I bypassed the main obstacle, so no need for help now.
