Here is General Tutorial about GPGEMMC for EMMC Soldering etc....

You have to use Right Tool to Soldering. Good Iron, Good Thinnest Needle you can use becton dickinson's thinnest Needle, Good Paste & Good Solder & Good Non Shaking Hands

so here we go

1st of all you have to dissemble your phone and check test points almost every Testpoint which is nearby EMMC ic or Cpu will be Glued. so you have to remove that Glue 1st

for Removing Glue you can use this type of needle



you can find this needle to any Medical Store ask them for becton dickinson's thinnest Needle

here is picture of Glue Removed from TestPoints
this Glue Removed from Samsung S4 i9500



you have to remove glue from all around that Resistance. Please Be Carefull do not pull off Resistance or Do not make Damage Print of PCB

after that you have to take Good Quality Copper Wire many countries calling them different names like Jumper Wire, Enamel Wire, Make sure you use Good Quality cause of Emmc is very sensitive and you must do any work with very care !! here is soldering on Samsung S4 I9500



Make sure there is no oxidation or Carbon on your Solder after You make Solder Wire make sure it's fine no Resistance Damage Also make sure you Not use too much Temperature this will make Change in value of Resistance and results will be Completely EMMC or Cpu Damage





for cleaning make sure you use AntiStatic Brushes and Tools !!
