* Steps 3 & 4 - It would help to mention that each connector has a movable locking mechanism and that the "black" item referred to is the movable part. Also that it is secured with yellowish transparent tape that must be pulled off prior to unlocking. Unlocking consists of flipping the black plastic piece up 90 to 180 degrees and locking is the inverse operation. Lastly you cannot get your finger under the black piece, but your fingernail might work. I was initially very confused, the only black thing I could get my finger under was the ribbon cable. I did in fact manage to pull the cable loose before realizing I should have removed the yellow tape and unlocked the connector.
* Step 7 - I'm not sure why the 3rd screw is mentioned. I did NOT need to unscrew it.
Hope this comment clarifies things for the next person (and thanks to the original author).
This guide was quite useful - until I came across it I had no idea it was feasible to replace the audio jack! There were a couple of areas where the instructions could be improved, namely:
* Overall - the description of "Easy" must be relative. Once you've done it once it might be easy, but although I've many years of experience tearing apart computers, as a newbie to opening a tablet device I found it quite tricky. Next time it may feel easy, but that is misleading for a newbie.
* Step 1
** On my device it took a LOT of force both to get the tool inserted and at various locations as I slide it along each side. Also, going around each corner to a new side was also tricky.
** Unsure what "Make sure to remove the lock key" meant. What "lock key"?
** Although there is no true hinge, the two ribbon cables imply one should treat the device as if hinged along the conventional "bottom" (where the USB and HDMI ports are).
