No HSPA+ since teardown

A week ago the power button on my Nexus 5 got stuck. I would press the power button and the phone would behave as if I was holding down the button even though I wasn't. I watched some teardown videos on YouTube and opened up the phone, took out the motherboard and gently squeezed the power button connectors on the board. This seemed to have worked because the button is no longer stuck and the phone is working. However, I have not observed the H indicator on the signal icon since then, only the E. It doesn't matter what I set the preferred network type to and I know there is HSPA+ coverage in the area. Is it possible I damaged or disconnected an antenna when I opened the phone? I have noticed no other issues. EDGE is working as well as can be expected.

回答此问题我也有这个问题

这是一个好问题吗？

On step 8 of the iFicit teardown you see the blue boxes indicated antenna spring contacts. Make sure they are pointed up enough that they make contact with the antenna on the back cover.

They are making contact as far as I can tell. Since I posted I've also noticed that I'm getting poor signal quality indoors.

This is what worked for me. Look at the picture of the board in step 10 of the ifixit teardown. There are two round connectors at the very bottom of the board, one on either side. When you take off the back plate there are two wires connected to each of these. One of mine wasn't seated properly.

It would be more helpful if you tell us the model of the phone and what network you are using.

Anyway, do a software reset to start with.

Tom,

Why do you think factory reset should solve this issue ?

Thanks,

Sagi.

Some bad software settings probably locked the network preferences. Anyway it's just a standard procedure.

I have the same issue, but the issue was caused by me dropping the phone. I dropped it on concrete, the back cover popped open in some places, of course I was furious for me being so clumsy , i closed the back cover and put the phone back in pocket... 2-3 hours later I was on bus, took the phone out to surf the web or whatever, noticed EDGE indicator, I was confused cuz I was in a H+ area and this shouldn't have been happening. Got home I have a 3G zone there, but nothing. I downgraded to 4.4.4 from lollipop, didn't help, reflashed to 5.0.1 didn't help, I couldn't fix it. Sometimes in some places it gives me 3G or H+ but the coverage indicator is half greyed out, on EDGE it's always full. So I don't know what to do. I don't have warranty any more, I can't even RMA the device. Can anyone help? Will it be a good idea to replace coax antenna cables?

Re seating the small coax cable plugs (tiny little plugs on grey wires) that run either side of the battery fixed this problem for me. One of them became unplugged when I dropped the phone and the problem confused me for a week. Fixed now :)
