I found http://forum.xda-developers.com/show....php?t=1823421 but I'm stuck.
0) Have your CPUID and/or SBK to hand, along with the A500 APX Flash Tool downloaded. <<=== I don't know how to get the CPUID
If you have your CPUID but not your SBK, go generate it now with http://a500bootloaderflash.tk/sbkcalc/
1) Download the root zip from http://www.blackthund3r.co.uk/hostedfiles/CWM_ICSRoot and copy it to the device's internal storage over USB
2) Load the A500 APX Flash Tool and enter the bundle market. View the bundles for the default repo (a500bootloaderflash.tk) ,<=== the Tool unpacks as a .exe. I'm on LInux.
I searched for how to get the CPUID and found this: http://forum.xda-developers.com/show....php?t=1624645
(2) From your device using Terminal Emulator App
looked promising but didn't say _how_ (or which Terminal Emulator app)
Pointers or links would be nice.
