It went so well the first time I did it on June 19 that I decided to do the other tablet since we have a matching set. Once again, it went well. It took 20 total minutes flat from setting up to cleaning up.
These instructions were spot on. However, after the last step, I would include that if the replacement micro USB port does NOT come with the metal shielding (as was the case with a 3rd party distributor), then this needs to be removed from the old port and installed on the new port BEFORE screwing the new one onto the board. When prying off the metal shielding from the old port, do so from the sides and lift up from the port end since it pivots from the back of the port module.
