T561 emmc problem
 

i got this tab.. problem was data not wipe during flashing...
so i know its PROTECTION PROBLEM..
so i opened the tab and saw the tab has scandisk emmc....
so i ordered another emmc so that i can replace it...
but i have the follwing problems.....
i dont want use hot air to remove emmc so i want to grind the old scandisk emmc... but i want to read 512 dump & excsd before grinding the scandisk emmc...
but when i solder emmc wires directly on board it doesn't detect... i tried everything but it didnt connect...
so my questions are:

is it safe just grind away the scandisk emmc without backing up anything?
if YES then can i just use md5 and pit and just flash it using easyjtagpro?
if NO then how can i make it connect so that i can do some backup?
what is the most important backup to do (excsd? 512 dump? or boot if any?)
i saw a tip on pinout photo talking about pullup resistors..
must it be 200ohm each? or 100ohm each on both data and cmd lines?
please im waiting for your urgent replies
thanks in advance

Please someone should answer my question... i need help
