4) Market issues. Market issue "may" still exist. This is common on tablets that are not really supported by Google as a registered device. Most users have no issues but sometimes there can be, The 2 issues that seem to arise when your FIRST TIME try to use the Market are:
A) Cannot logon; "Cannot establish a reliable data connection"
I have tried to recreate this and troubleshoot this. My belief if in fact this happens sometimes when Google servers are doing something or something is going on with them. WHen I had this happen once I simply waited a while and it worked later. So I cannot help too much here. My only suggestion to try is this
a) Install a root file manager like root explorer or ES file manager (enable root access for them)
b) Go in with the file manager and delete /data/misc/imei/imei or data.dat which ever one exists
B) Limited apps listed; I have reproduced this and know how to recreate it and fix it! This has to do (I beleive) that after a factory reset or a flash the tablet creates a ID based on some other IDs and a random key generator. Sometimes this ID Google does not like. So we have to clear that and reboot.
YOU DO NOT EVER NEED TO REFLASH OR DO A FACOTRY RESET TO FIX THIS!!!!
DO the following
a) Again using a file manager that has root access go in and delete the follow folders from the /data/data directory.
com.android.vending (not com.applib.vending!)
com.android.vending.updater
com.google.android.gm
com.google.android.gsf
b) Reboot and do nothing else but run the market. YOu should get a prompt asking you to accept the Google terms of service. If you did not you did something wrong. Do it again. If you do get the prompt, accept and now the Market should work fully with TONS of apps showing up.
