[Q] 3G network not working after drop

Hi,
I would like to ask for help and/or any suggestions that might lead to the solution of this problem.
Basically I was skating and had an accident and the screen cracked, which i got replaced, but then at the same time the network was connecting and disconnecting continuously. It sometimes shows the bars like there is good signal but i cant make calls or send texts, as soon as i try it shows a cross and no signal.
I tried everything from factory reset to changing the Radio/RIL to changing the rom. After a while I switched it to GSM only and it worked!!! So now the phone works on "2G" only which is annoying as the internet is quite slow. But as soon as i switch to Auto between GSM/WCDMA it goes back to doing that problem.
I would appreciate any suggestions, It might a damage to the mother board, but everything seems to run brilliantly on the phone.

Hi I've encounter the same accident too, but luckily I'd use casemate barely there, so it proof had protect my phone. You may need to sent for repair, as it sound so serious.

run an RzrU on the phone and send it to HTC or your carrier for repair. Definitely one hundred percent hardware failure

Is the bottom plastic cover cracked from inside or damaged in any way?

htc external speaker issue

i tried searching the forum but couldnt find any info on it.
the external speaker on the htc one x stopped working but if you tap the back casing the speaker works for few hours and then the problem comes back again. i tried flashing a new rom it works for a bit and and then had the same problem again. is there any suggestions what could be done to solve this issue?

Maybe you got a defected HOX ??

found the fix. it was the contacts that connects the speaker module to the board, may be the contacts( the same type of pins that caused the wifi issue) on my HOX got pressed too much i guess, probably going to solder the pins when i get home as of now have it taped up for the testing

i had the same problem when i openned my HOX, after closing, back button led and speaker didn't work, i disassembled and reassembled again and it works, so watch out if you'll open it!

I see ... Hope you get it fixed then

soldered all four connection, did a test didnt work so i played with the speaker connection a bit and it worked. i guess the speaker had a loose connection or something as of now placed a bit of masking tape and closed the housing. working so far now. i guess the problem is with the chip where speaker is plugged

Had the exact same problem, although it degraded to the point that tapping the grille only brought sound back for a second in the end.
Got HTC to repair it along with the wifi.

not a common problem, though someone did mention something about problem on 2G or cdma on LOS14 recently, maybe try update modem or flash a different one.
(if you have I9195 here are modems that already been extracted from stock roms https://forum.xda-developers.com/ga...dem-samsung-galaxy-s4-mini-gt-i9195-t3390780)
If still weak signal then it could be poor grounding of pcb or antenna connection, remove battery, remove internal cover, check connections/reseat leads also tighten screws of motherboard/remove check for tarnished/corroded contacts. (if you put a small piece of wire on the test point (micro rf connector) with battery in you might suddenly see signal strength spike meaning it's your antenna/connection is the problem)

I will send it to the service and replace the antenna.

it might not be that, did you test antenna with little cable on test point (just take battery cover off). I was just giving an idea of possible problem. Some people have found just tightening the screws that hold the motherboard fixes it. It could be something else entirely like eg software, is it the same on all modem/baseband & other rom?

GPS not working

I bought a supposedly new HTC 10 off ebay a few months ago, and just realized on a recent trip that location service is using only wi-fi & cell. Once I am out of signal range, I get no location data, and GPS not working.
The phone came S-OFF and running WWE software, which I have changed to US unlocked using RUU, currently running 2.51.617.32, baseband [email protected]_76.02_F.
From a previous contact with HTC, they told me the serial number is that of a Sprint phone. I am assuming that this is a refurb of some kind.
I have installed GPS Status and tools, and the app can see the satellites, but cannot get a fix. Hardware check says that the sensor is OK. I have cleared AGPS and that made no difference.
Changing data from 3G to LTE to Auto, or on & off (per a couple threads at xda) made no difference.
I am unsure what to do next. Phone works well otherwise. Would flashing a Sprint radio help? perhaps a different kernel?
Any advice appreciated. TIA.

I had this issue after a battery replacement. Essentially this thread worked for me. Once the HTC 10 was opened up and the rear casing removed, there's a v. small copper prong located next to the headphone socket and it needed a bit of careful prying so that it could make contact with the back plate of the phone once rehoused.
So it could be that your new phone off ebay is a refurb and has been previously opened?

I would try a Sprint ROM before opening it.

finally found someone with some 10 repair experience haha. I just noticed my GPS won't lock, assuming it's due to screen/battery repair. I have over 5yrs phone repair experience, so salty i am in this spot.... But I have been many times with HTC repairs, and eventually figure out hte querk. Any other insights? I opened it up yesterday and couldn't get a lock still even without back frame shell on. I then noticed the top pin above the headphone jack was depressed most likely due to prying when opening, i carefully bent up and it didn't break, now making connection with back cover frame but still no gps lock.... also try reconnection of the top daughter board flex where hard gps chip lives....
Update: Twas the pin at top, and flashing RUU that got me up and running GPS again! woohoo!

Thanks by the help!
The last week I change the battery and I lost the GPS signal. After reopen the phone, the GPS pin it was in bad position. After move the pin, the GPS it is working again!

bad wifi reception due to faulty hardware

Hello community,
due to a water incident I had to replace some hardware parts as microphone and finger print sensor.
The navigation proximity buttons do also not work, but I did not replace them.
After this replacement, the phone worked 3 months fine....then I replaced the main camera because it didnt focus anymore.
Since the camera replacement I have very bad wifi reception. When I am right next to the rooter, it is working but unstable. Thats why I suspect an antenna/hardware problem or another hardware issue. I did replace the black coax cable (also a used cable) next to the battery already, but this did not resolve the problem.
On the software side I did a complete reset. Actually twice because I had to unlock the bootloader and then did a reset. Also not resolving the problem.
- I am now wondering, weather there are more or different wifi antennas in the onplus 3 except the black coax cable.
- Does anyone have experience about the sensitivity of those coax cables? The replacement cable I have is also from a used phone and has some usage marks.
- Anyone another Idea, where the problem can be?
Thanks for any suggestions!

The problem can be the constant opening up of the phone and meddling with it.

I have the same problem with my oneplus 3, i too had to change my back camera because it didn't focus, which after many attempt didn't work and i ended up using a magnet right next to the camera.
I purchased a coax black cable but it didn't solve anything.
I also have switched between a numerous amount of rom and i can tell it's hardware.
So it's either the main board that suffered from the chirurgical operation we had to do or the back's antenna that are faulty, i don't think removing the camera would make any difference.
My wifi reception is really bad and i can't get a decent bandwidth even right next to the wifi...
I'll have to re-open it to change the amoled that just broked so i'll keep you updated.

Changing the back of the phone can make any difference?
Thanks!
