I got a better solution. Like Dieter, I added a 10uF cap instead of
replacing the capacitor altogether. However, instead of using a wire, I
placed the new capacitor directly adjacent to the original cap. If
looking at the photo Dieter sent originally, I placed the cap
diagonally, bottom-left to top

Oh, so I wasn't the only one with that luck. When I tried to

For testing the process I tried to do the rework on a NEO1973 and
promptly got into trouble - I was not able to remove the capacitor! Is
it possible that it is glued to the board?
I tried a hot-air rework station but it kept stuck.
Then I tried with two (!) irons simultaniously heating both ends of

What a nice surprise to have after a week away :-) Many thanks to Dieter and
everyone else involved.

Just to mention it once again, and to stop a possible stampede:
AT%sleep=2 (sw-fix[1]) has fixed recamping reliably for 100% of affected
devices. Not all devices suffer from #1024, actually it seems it's only a
small percentage. FSO is capable of switching to AT%sleep=2 even
automatically[1].

Just an additional heads-up. Daniel reworked my device on the hardware
workshop which was part of the first FSOSHR conference last weekend in
the LinuxHotel.

First of all: Congratulations for finding a solution!

Dieter, I think we all owe you a big applause for finding a solution
for this bug. #1024 is as old as Openmoko or even predates it. Many
people have tried their luck at solving this problem and it

Dima,
wow this is excellent news!
How long did it take you to do this fix? How hard was it, how about
likelihood that the phone will get damaged in the process?
Maybe we should publish a proper PDF SOP, wich some neat pictures and such?
Or roll it into the buzz-rework SOP?
More reports on this
I just performed this fix and so far the recamping is successfully
squashed. I'm not seeing any recamping (was fairly common before the
fix). Instead of placing the second capacitor away from the first and
using a wire to connect the two, I placed it directly adjacent to the
first, using some elect
