Here some help How to fix damaged golden pins in sim card slot

Hi, I posted an answer here in case this helps How to fix damaged golden pins in sim card slot

Hi, I had the same problem. Buying a spare motherboard from OnePlus is said not possible by them. I tried to unsolder the sim card socket with a hot air solder station. Way too risky as there is too much little components around. Overheating them may result random behaviors afterwards. Moreover, there is 13+ solrdering points not accessible. The trick I used is to replace the damaged pins. Here the way to proceed - We are considering here you already took the motherboard out of the OnePlus One. 1/ Needed tools - Office adhesive tape - A Dremel with a diamond cutting disk - Tweezers - Clock repair magnifier - Soldering paste - Hot air soldering station - A spare sim card socket adapted to the OnePlus - got from Aliexpress 2/ Procedure - Apply adhesive tape all around the socket to prevent small metalic particles to go everywhere and cause short circuits - Use carefully the Dremel to open the sim socket - Image below. Pay attention to the ejection mechanism and let enough material on left and right edges. -...

Good guide. I swapped my logic board with it.

However, It may be improved by changing the order of the steps to get more space and carefully work.

1. Remove the battery

2. Remove the hard drive and airport card

3. Remove the left speaker (at your right when working) to access more easilly to the connection board.

4. Disconnect the connection board from logic board

5. Remove the fan

6. Work on the connection board

7. Removing right speaker helps during reassembling (a small rubber pad is under the logic board at the top left) and ease the ribons access to plug into zif connectors.

8. Work on the logic board

This may help to reassemble as this provide more room to connect small connectors and provide better access to ribons

Step 28 seems useless if you are working quietly

As a hint I used some dessert plates to hold the screws for each part. This avoids mixing them altogether
