Ever thought that the vibrate motor in your OnePlus One is too weak? Want to upgrade it to a stronger one? Well, now you can, at the expense of one of the two mono speakers in the speaker block, and your warranty. Not for the faint of heart.
What you will need:
Step 1
Disassemble the OnePlus One. We need to remove the speaker block and speaker flex from the phone. Everything else can stay put.
Step 2
Using a knife, remove the speaker that shares its enclosure with the vibrate motor from the speaker block.

Step 3
Remove the speaker foam lining from the flex to prevent it from melting later on.

Step 4
Remove the vibrate motor by either:

Then re-install the flex into the phone.
Step 5
Install the motor onto the flex. You can do it by eye, or stick it inside of the speaker block first, installing it so the motor sticks to the flex then removing the speaker block.

Step 6
Solder the wires to the contacts. Positive is closer to the USB port, negative is closer to the battery. Make sure neither are touching the large conductive area where the old motor used to be. It should be ground, but test it before using it. Foam padding on the motor is recommended. The motor should come with one, but if it doesn't it should matter too much.


Step 7
Reassemble the phone.

Done! It was pretty self-explanatory - disassemble the phone to get to the relevant parts, remove the old motor, installing a new one, and reassembling it. I think the most important part is showing that it is possible to remove the motor and the method of doing so.
What you will need:
- Tools and disassembly/reassembly instructions from this thread: http://forum.xda-developers.com/onep...embly-t2979351 (shameless plug)
- A coin vibration motor (a 10 mm x 3 mm one that runs at about 3 V, either sourced from a phone that has one, or online (something like this but doesn't have to be exactly this)
- Hot-air rework gun and Kapton tape
- Reasonably proficient soldering skills

Step 4
Remove the vibrate motor by either:
- Desoldering the whole thing, motor contacts and all, using a rework gun
- Desolder the individual contacts first using a soldering iron, then the motor itself with a rework gun
Then re-install the flex into the phone.
