Sadly no, but have re-burned a Wheezy image which exhibits the same problems.Jim JKla wrote:Don't you have a copy of your old Wheezy image to try?
Okay... I can see a line which appears to be labelled X1 on the base. How would I tell which bit might be unstuck?mahjongg wrote:If both ethernet and USB die at the same moment, most often the problem is crystal X1 near the LAN8512 chip which has a bad solder joint, and one end has come unstuck.
Thanks. I did read it, but am too inexperienced with the electronics side of things to want to risk my warranty by playing around on the board like that.mahjongg wrote:You might want to read this thread:

Okay, that sounds like a plan. Here's my utter electronics noob confession - I found the letters "X1" on the reverse of the board... but I have no real idea which bit is the X1 nor which are its pins to prod! Could you provide an annotated picture, please? The bit I naively thought might be X1 (the part above the label, with the clock speed etched on it) seems to have 4 connectors.mahjongg wrote:just to see if it indeed the crystal, you could press down on the crystal while booting your PI, to see if maybe it starts working then. Simply touching one of the two pins of the crystal (with a metal pin or other sharp metal object) might also help it start, and if you are lucky the crystal might keep working, i have seen it happen!
Sadly, that doesn't seem to have helped - time to get a return set up and (re)join the queue. Thanks for all the ideas - if anything else strikes you, do let me knowmahjongg wrote:What is still possible is to put some force on it while booting it, to see if ethernet starts working. and to prod with a metal pin at its four contacts, to see if that helps start the crystal oscillating.
Which is way beyond my comfort zone (even on a $30 computer). So, kudos to Farnell who responded today to my return request, and have already arranged to ship me a replacement and collect the faulty one!mahjongg wrote:Yes, the real solution/test that the crystal is to blame, is re-soldering the four solderpads.
I was told today by Element14 China that I would have to wait 4-5 months, even after several emails. I think these companies are not unrelated, and don't understand what explains the discrepancy. I know other countries have other issues, but many seem related, or subsequent, to the same faulty component. If anyone from the Raspberry Pi side could turn their attention to the manufacturing/logistical issues, just a blog post for example, I think a lot of people would be grateful.MrHarcombe wrote:Which is way beyond my comfort zone (even on a $30 computer).

Looking forward to getting back on the Pi rsn
No indeed. Colour me a happy little geek - new Pi already here, plugged in and working. Feeling more then a little spoiled, considering the wait some are facing, but not wanting to look this gift horse in the mouth!mahjongg wrote:Ah, fine, so no (quoted) 5 weeks replacement after all... nice.
