From what I heard from support when the Bluetooth issues were first being reported, the focus for the development team will be on the SparkLAN cards, not the Redpine.

Iām located in Germany and would like to buy the new Wifi card together with the service to do the swap in Purism, ofc as paied service and also the transport of the L5 (maybe Purism has a location in Germany?, but also if not Iām willing to pay the transport international). Any ideas in Purism about such service? Thanks

I ordered normally, I think it was shipped from USA to Germany.

there is also separated firmware (BCM4362A2.hcd)for bluetooth butā¦donāt work.
Luckily I donāt use bluetooth but I would like everything to work with the jail

You shouldnāt have created it yourself. Lack of it means that you need to flash the firmware jail.
Thatās not the firmware you should be using.

I plan on replacing Redpine with SparkLAN card this weekend. I got a set of tools for servicing mobile phones, including multiple plastic pry tools, so I should be set.
Does anyone who replaced the card has any advice, what to pay attention to, or maybe what is the easiest way to disconnect the antenna? Iām used to repairing my own devices, but Iām kind of nervous since connectors are tiny and sensitive.

Some random thoughts:
- There is a brass pin in the middle of the edge under the card that may want to ājumpā and go missing, so be mindful of that (and itās sibling that is under the modem card, if you remove the whole plastic frame)
- When removing or connecting the antenna connectors, always make sure the movement is up-down (not in an angle. That way, if the connectors line up, they will connect and if you miss, the force you apply is doing least damage, compared to any twisting or bending. And the wire connector is more likely to break, which is good, because itās less expensive of the two - you do not want to break or remove the connector from the board. The cable can be sacrificed.
- The connectors on the new card are in different places so you need to route wire via a new path. There are a couple of methods and at least one that requires to bend the wire to a sharp angle, which Iād be careful with. Optionally you can remove some plastic to make a new pathway for the wire (but be mindful how the cover attaches).
- @ChriChri has good pics on this and there is also the L5 disassembly video
- As the cables connect in a new place, the cover does not offer any support to keep them pressed on the board anymore - you may want to add a piece of plastic or thick tape on to the underside of the cover, so that it helps secure the connectors (so they donāt easily pop out of place). Thereās a small bumb there you just need to extend a bit.
- Avoid carpets and wool mittens

The procedure involves disconnecting the cell modem as well, when I did it I unknowingly broke off one of the cold soldered u.fl connectors on the board, so now Iām operating on one antenna. I too used a plastic cell tool I had and still managed to break it off. When I have to do this again I am getting these tools specifically designed to remove and attach these cables:

Thanks for the advice. Iāll see if I can find those locally, because they will take long to arrive.
I wonder if I could 3D print the tool using PLA or ASA.

I think you can find the dimensions for the tool someplace I think I found it once.

I found these two on thingiverse:
The connectors on the modem and wifi card are U.FL, or am I mistaken?

Thank you very much for the info. Iāll print these out of PLA tonight, and see how they turn out.
