I replaced the glass on my Ipad 2 and did not read up properly beforehand.... After reassembly my wifi was awful although bluetooth was working OK. I bought a new wifi/bluetooth antenna and redid the procedure, making sure to be gentle with the new antenna and placing it right.

I reassembled again and wifi is perfect, I thought everything was good. Only now did I notice that I can no longer connect to my bluetooth logitech keyboard! I wondered if the keyboard was bad (it is new) so I tried to find my Ipad's bluetooth signal with my PC and it does not see any bluetooth devices.

Bluetooth settings on the ipad is not greyed out. It searches, but does not find anything. What might be wrong? Wifi is great but it seems I traded wifi for bluetooth, boo hoo..... =( I just updated to the latest IOS with no improvement.

I dismantled the phone again and concluded that the digitizer cable was kind of loose (don't know if that affected anything, but i put it down firmly this time). I had 2 problems, the cellular connection I mentioned plus the phone would charge to 3 percent, die, and then repeat the procedure. What I did was I took out the battery, the tin plate above the cables, and lifted the dock connector. So I did not redo that much. I cleaned all contact surfaces as I had been told but chose to not do before.... I also took out the grounding clip by the battery connectors and bent it upwards quite a bit while also peeling away 2 mm of the black insulation material on the back of the phone to make sure the grounding clip connects well to the back of the phone. I also cleaned that surface with window cleaner, which is basically isoprypol alcohol as has been recommended. The cellular antenna connector I pushed down firmly to make sure it was connected, I was gentler the first time, now everything works.

Ok, I did all the steps and phone seems to be OK, wifi is actually working again, yaaay.

But cellular connection is messed up. It will have full reception (5 pins) for about 10 seconds, then drop to 1 pin for a couple seconds, then go into "searching" mode. After a few seconds in "searching" mode it will go back to full reception and the process repeats itself in a timely fashion, over and over again. Obviously I messed up somewhere but where? Which connections are faulty/beyond repair?
