I received my M8 and 21mm Elmarit back from Leica last night. They returned in separate boxes via second day air.
They replaced the CCD due to the green blobs and cloor pixels, did the complete upgrade, vulcanite, and firmware upgrade to 2004, in the end I now have a M8.2 with a silver hot shoe and red dot with a one year warranty and they sent me a $150.00 rebate for my next purchase.
The 21mm Elmarit, they rebuilt to factory spec with some new and while the lens was in for that, I had them code the lens.
Lens feels like it did when I took it out new, the M8 now has the discreet firmware feature, fresh restart on the shutter actuation count but lost the fastest shutter speed. The new shutter release feels much smoother and noticeably quieter than stock. I'm heading out soon to test this all out so I can report any problems with the repairs next week.
