iPhone 6 keeps searching signal, faulty u_qpoet?
Hi guys, I have an iPhone 6 here. The phone has signal issue, keeps searching. In the settings the ICCID, IMEI and Baseband are all present. Upon testing, I found no voltage detected on VPA_APT line. I know VPA_APT line is powered by U_QPOET chip, so I replaced the U_QPOET chip, unfortunately it made no difference, still no voltage on VPA_APT, phone still has no signal. I also tested the coils L4001_RF and L4002_RF, they both have 3.9V, which I think is normal. I don’t know where to go next. Any help would be appreciated!
Is dit een goede vraag?

Do you also get IMEI displayed when typing *#06# in dialer? That grabs the IMEI straight from the baseband chip.
There's some pretty good info from this thread:
Constant searching, no signal..

Hi Ben, before replacing U_QPOET, yes IMEI came up when dialing *#06#. To be more specific, before replacing U_QPOET, the phone showed “no service”. But after replacing U_QPOET, the phone showed “searching”, no IMEI came up when dialing *#06#. I installed the U_QPOET twice, made no difference. :(
