No signal on sensation 4g

hey guys!
I have a bit of a puzzeler on my hands, hopefully you guys may be able to help me out!
I have the Htc sensation 4g from Vrigin canada
A few days ago i noticed that my signal strength was at 0, and i was unable to make any calls or surf the web.
So i go to virgin, and they set me up with a new sim (or three) to no avail.
I then call tech support, and they inform me that, simce my phone is over one year old, i cannot have the phone covered under the warrenty , no insurance me must fix the phone myself.
some information about the phone : I am s-off, running the latest radio (from here http://forum.xda-developers.com/showthread.php?t=1202867 ) on android revolutions's stock ics.
I believe i have tried everything, but maybe i missed something, here is what i have tried:
remove battery
factory reset
new sim
update radio
update ril
update firmware
lift connectors on back of phone to insure proper connection to back cover
try new back cover
remove old sim/sd reader replace with new sim/sd reader
return to stock rom
So that's that, what do you guys think? Do I have a bad radio transmitter/receiver? bad main board?
Every thing else on the phone works, even the wifi and fm radios.
I have noticed that occationally the phone will show a couple bars, but upon calling it says that i am not registered on the network. most of the time the phone reads no signal no network provider under settings->about phone->network
I really appreciate any insight that you may be able to offer!!
Thanks!

So your provider is not willing to help? If you are paying your provider monthly and your device isn't registering on there network I would give them a call. Simply state your device is no longer registering on there network and ask them what are they going to do about it? I would be furious if they refused to help me because device is out of warentee! Sounds like your kind of stuck . You have tried everything. Perhaps give your provider one more call and see if they can at the very least trouble shoot your device. Just because your device is out of warentee don't mean you still don't pay them monthly for service. By chance have you tried a new sim card? Just a thought....I do hope you get this issue solved soon. Best wishes

thanks for the advice, I believe that I will give them a call tomorrow and see if there is anything that they can do for me...

ok guys, I managed to get my phone signal back up and going once again, but it was no easy matter. for those who may happen along from Google or what not, here is the solution:
Buy a sensation with a busted screen, remove guts, place in your phone, re assemble, make phone calls again.
I initially just swapped out the main boards, thinking that the problem was with the antenna connections or something. I put my phone back together and still nothing. deflated.
I took the phone back apart and swapped in the flex cable, antenna connector cable, and the board at the top of the phone. after putting it all back together everything worked, I'm thinking that replacing the top portion of the main board was all that needed to be done; I replaced everything just to be safe.
so there you have it, i hope this helps anyone who stumbles upon this with a similar problem. my problem was a hardware problem.

No signal

Good day, today I dropped my phone don't know if it lost signal after this didn't notice until I tried to make a phone call but now there no signal, can't make or receive calls, I notice that at the bottom of the screen it shows my service provider name and next to it says no service so don't know it its hardware related or sim, do you think that if I reset the phone it might work again? Thanks. Right now can't test because I'm at work, but in general information on service it says disconnected

Flash stock with fastboot, if it's the same, it's hardware I'm afraid.

Thanks a lot did already, tried everything seems hardware related, noticed that it also lost nfc connection wondering rich part should I replace to fix it, if only has to do with antenna or the whole mainboard

The NFC radio and antenna are connected to the back cover. Try popping your back cover off and on again.

Thanks already did and nothing, could it be related to some other piece?

go to your dialer app and type in #*06*# and see if a number pops up (your imei number) (dont post the number here)

Did too, also the *#*#4636#*#* and checked if signal was turned on, tried sim in other phones works without problems, I noticed that nfc is not working too, guess it has to do with a piece of hardware as far as I know both antennas are in the back of the phone. Took it to service and they told me it has no problem physically, this is driving me crazy

Also checked that it has no reports of being stolen, imei seems correct and legit checked it also on a site to see if it's valid and its working, it starts with a 32.

My phone wouldn't connect to any network after being in airplane mode on vacation for a week, acted like no signal - empty triangle instead of bars. I called my cell provider (T-Mobile) and after a new SIM and a factory reset they did something on their end because my phone was trying to connect to a tower that didn't exist. I'm a little fuzzy on what they actually did, but it worked. I actually had to do it twice over a couple weeks before it stopped giving me trouble.

thanks friend will have to go and check with them , dont know if its the same because my phone has no cell provider it accepts any sim you insert to it

Hello
Hello guys, I am on the same boat as Valholy described.
My phone fell on the ground from my hands. When I took the phone from the ground... it was still working(it wasn't shutdown nor restart), I only noticed that there was no more signal. Tried to restart/shutdown, factory reset, different sim card but no luck at all... As Valholy described it shows provider's name on the bottom of the screen, but there is no signal yet.. It seems like hardware issue. Any recommendation to fix this issue?
Did you fix your phone yet, Valholy?
Thank you

bump...
any help please.
thank you

Nexus 5 "No Service, SIM card ok"

I have a nexus 5 "hammerhead" running the latest version of android marshmallow 6.0.1 .
My issue is, the device wont detect any network signal. At first i thought it was a software issue so I downgraded to lollipop and kitkat but the same issue still exist.
All I see is the network provider name, and beside it 'No Service'. I really dont know what else to do, unless this is a hardware issue. Anyone here had experienced the same issue and have it solved? Or am I just going to have to turn this device into a tablet. -___-
p.s. The screen broke and was replaced, and after return of the phone this happened. Is it that the phone repair guy damaged my device?
Plz help!?

Is the imei okay? Are both of the antenna wires properly connected?

yes i can clearly see the imei #. ..and about the antenna wires, yes both are connected but just that the white wire seems abit off. but i tested the continuity and it seemed to work.

The imei is the same before and after the repair?
Did you remove the motherboard and examine it for signs of damage or alteration?

Yes I did. Motherboard checked out ok. Just can't understand why no signal tho. Wifi and Bluetooth works well. And to answer your question, yes imei # is the same.
Also, I was told that the phone fell before the screen replacement and that's when the issue started.

Even if the antenna wasn't connected, it should be able to pickup some amount of signal. If that's not the case then I'll just have to replace the cables and the lower PCB also the speaker area.

Maybe the drop caused a loose connection on the motherboard?
Did you try pressing against the antenna connection points on the motherboard with the back removed?

Well not entirely.. All I tried was checking the antenna wires (which I realized are just the WiFi antennas) and also, tried placing a copper wire in one of the testpoint area that's dedicated to GPRS.
Is it possible that the transceiver may be damaged? Or that's not possible from a simple fall.

Imei is not blacklisted?

Nahh I doubt it. Phone was purchased unlocked was working for a while.. Fell, signal went ..broken screen.. Then once the screen was replaced, inserted sim and it detected sim and also the network but won't gain any bars (service) nor will it detect any other providers.

I would check the imei just in case.

What would I compare that to, apart from what the phone telling me?
I'm registered on the cell network, but no service despite the adjustments of changing the network type or by dialing *#*#4636#*#* and making alterations there.

You can check the imei in swappa.

same problem
same problem with me sim detecting i can see card name but no service in signal bar wifi bluetooh all ok

Pretty wierd

Yeah pretty weird if you ask me. But if you do get a solution to that issue please share :good:

According to Rameeze87, possible hardware issue. Here's the link http://forum.xda-developers.com/google-nexus-5/help/nexus-5-network-signal-wifi-ok-t3310047
Had no idea couldnt duplicate threads, then again it did help to justify the issue.

same
Mine is doing the same thing. Once in a blue moon it will show full bars upon first inserting the sim for maybe three seconds and show provider then drop all the bars and say no service. Dont think there is a simple fix.

Having this issue right now with my wife's phone. Power button broke and was going through endless power cycling so I removed the power button. Got the phone working but will not connect to network. I have checked everything 20 times.
Any solutions?
Sent from my LG-H811 using Tapatalk

Yup.. same issue. Phone fell and no mobile signals since (sim gets detected). Everything else is working fine, checked the antenna wires and they are connected properly... Anyone here who was able to get the signals back?

similar issue here in the uk.
N5 phone worked fine for 2 years with a 3 sim.
i changed the knackered battery and that all works and charges ok.
but the 3 sim now wont work(but it does in my motorola moto g), the only sim that will work in my N5 is an O2 sim ???
why does one sim work but not another, the phone isn't locked to a carrier?....

Antena Problems?

Hello! Tonight, it appears that there's something up with my phone. It informs me that I can only make emergency calls and I can't make calls nor send texts either even though its showing me five signal bars. I have to reboot into safe mode then back out again in order to get it fully functioning without hiccups.
I've searched around for a couple of hours and saw that people are reporting some hardware fault. Although they also said that their phone was unable to search for available network operators in their area. Unlike theirs, mine is able to search for available network operators.
Is it possible that the charger I'm using is causing problems? I'm using my dad's Zenfone 2 charger brick with my original samsung cable. I've ordered an Aukey quick charger though.
Is it also possible that the phone's gotten quite hot that it's already messing and needs to cool down? I've flashed a bunch of times since I was trying on some of my mods.
My phone's a K variant and it's been rooted for quite some time so that's not the case. I've also tried inserting my sim card in a different phone and it seems that my sim card's not the problem as well. I hope my phone's just having a bad evening lol.
Any ideas on this?

The only thing I can think of outside reinstalling roms and what not is to flash a newer modem only, on the handset. I honestly can't comment on if the charger could be the issue

It sounds like a software issue, not hardware, as you can get it working. I'd flash your latest stock, then factory reset and see what happens.

Problem with reception on my OPO

Hello,
I have a big problem with my OnePlus One: After it detects the SIM and I entered the PIN the phone isn't getting any reception. I tried multiple SIM cards. I am actually having a IMEI, tried all APNs, which are available by the providers and I even tried multiple ROMs (I have no problem with erasing data or so, 'cause it's my backup OPO)
But in each single ROM the One isn't getting a signal.
In the settings I can actually choose the providers so the chip/ module ist working (maybe interesting to know: I repaired the phone's screen, so of course i fully dissembled the phone and first i thought maybe I cracked some parts, but the motherboard of my normal OPO is working fine and gets reception WITH all of the parts from the backup phone. In the other way the "not working" motherboard is also not receiving reception with the normally perfect working parts.
So there are only two ways:
Some software isn't working perfect, especially the modems' one, because I can't connect to any network. (I already typed in "+#+#4636#+#+ to see if the phone is getting a signal and yes it does!)
OR some components of the chip on the motherboard broke by the repair, but because it is getting a signal this isn't this way I think.
So I am over. Do you have any hints like a special modem that I can flash?

hi have you tried resetting the oneplus one back to factory defaults

only resetting to the defaults no, but this should also be done by flashing a ROM to a completely wiped phone.
But now I have done this, but this didn't change something.

Hey,
I have a similar problem but with 3 and 4g. It works for a while then it stops : phone shows full signal icon but I cannot make calls or connect to the web.
However my 2g works fine. Try downgrading to see if it changes anything?

My problem is that I'm not even getting a signal in the notification bar. I am only getting a signal in the hidden menu (call *#*#4636#*#*)
A change between 2g/ 3g and LTE hadn't changed anything and a swap with the frequency via the hidden menu also didn't changed anything.

OK. I will try this than I am back at home and have access to a Windows VM.
Anyways thanks to any suggestions!

Make sure the antenna is plugged in.
Worst case scenario, IMO, is that your antenna connector has broken itself from the board at the trace level.

They said the only thing that they can do is to "repair it", so they will replace it, but it would cost so much...

No. It happend a week or two ago. I started my phone in the morning and there were 2 problems: The touchscreen didn't reacted to anytging, but the LCD was working and the signal icon in the notfication bar didn't showed anything. (I didn't use a pin with the SIM)
So I restarted the phone with a long press (about 10 seconds) on the power button.
Nothing has changed so I thought that the cables where loose or so.
I took it apart and disconnected every single connection inside. Put it all together then. Touchscreen was working again, but nothing has changed by the signal.
So as I already wrote:
So I swapped the motherboard with my other OPO and it happend.
So the antenna and bottom part is working.

Check the connection of network antenna again.It might be loose.

Problem solved. It were some "not perfectly working SIM cards" as my provider wrote me in a letter, which came with some brand new SIMs, which are working fine right know. Don't' know why they were all working in the other OPO, but now the problem is solved!
Thanks for any suggestions!

I'd still check it physically. I practically tore my hair out for a few hours after receiving a friend's phone after having its screen replaced. Similar symptoms wherein you can ping for networks, there appears to be signal from the debug menu as well but it just wouldn't connect to a network. I suspect that once it tries to connect and sends the required voltage to do it it fails as the antenna isn't there. The board and the connector itself is a bit of antenna on its own + you may be in an area that has very good reception in general.
