[Galaxy S I9000 General] Larry4404:
Newbie Heimdall problem - Galaxy Tab 3 10.1

Hello there folks!

My name is Larry and I'm a relative newbie to Android my previous phones having invariably been Nokias. I DO have some previous flashing experience having "Delighted" my N8 and both my 'old faithful' 808 pureviews.

I was given and Tab 3 10.1 WiFi (GT-P5210) and off the back of that VERY positive experience invested in a 4G/LTE GT-P5220.

I am a die-hard Linux user (Debian XFCE) currently running 32 bit Debian 8 on my 'collection' of Asus eees, so I am no stranger to root & the shell. I do have one WIndoze 7 box which was last used to flash the 808s but it is so painfully slow I cannot bear the wait while it boots and it is shortly due for the Debian treatment

OK, my problem. I am looking to 'root' both my Tabs and have found the relevant CWM packages to do the necessary.

I have installed Heimdall (both from the Debian repos and later from the packages from the developers site just to be sure) and it appears to load OK (EXCEPT when running as root - see below).

I put the Tab(s) into Download mode, connect using the Samsung USB cable(s) and ask Heimdall to detect the device, which the output screen says it does.

Then I try to Download the PIT from the device and I get:

Heimdall v1.4.0

I've left the thing for ages but it never re-attaches or does anything else.

Trying to Print the device PIT gives:

...and again it stalls and never finishes.

When running as ROOT, starting Heimdall Front End gives the following error before the front end starts:

larry@debian:~$ su

Password:

root@debian:/home/larry# heimdall-frontend

Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed

Then all the previous errors repeat themselves.

I've tried this on both devices, 3 Asus eees all running Debian 8 XFCE, with 4 different USB cables, two of which were brand new Samsung ones. Oh and yes, I tried all 3 USB ports on the EEEs.

I've googled all the errors and searched on here - no luck so far. Anyone got any ideas?

All help gratefully accepted folks.

Thanks in advance,

Larry :o
