No 3/4G after water damage - Nexus 5 Q&A, Help & Troubleshooting

Hello,
Someone gived a nexus 5 to me, because it was dead (dropped in toilet)
I took it apart and cleaned all with alcohol, and olmost everything is working fine now..
But when i place a simcard like mine (T-Mobile NL) it will give an G icon above with full coverage.
And it will stay @ G only so seems that 3/4G is not working anymore.. i THINK that the black speaker box
is damaged (where the 3/4G antenna is in?) Can someone tell me if i can test this?
And yes APN stuff is all ok. tried factory reset but still not working.

I think its solved.. i tried an other carrier today (Telfort) that uses KPN network. it said R above @ signal, and i was able to download / internet very fast.
And i want to give the phone to someone that uses Vodafone. Going to check this tommorow.

My gf has KPN to and i wanted to give the phone to her, so all fine! only wifi is not stable... can i get a new wifi antenna somewhere? (its in the back cover) or do i need to get a new back cover?

[Q] Three 3 UK users please read

Are you having issues where the phone's internet cutting out? I'm trying to work out if its an issue with the phone or the signal in Manchester.
The phone will be working fine for texts and phone calls then when I go to use Internet radio, Marketplace or Internet browser quite often the internet will drop out.
Hi no .
My phone is behaving but does have the 3g to H problem where it flies between the 2 . Although this does seem not as bad as other users are experiencing
Sent from my HTC One S using xda premium
Its literally driving me insane. Its about 6/10 times I go to use the internet it wont work! But if I do get it to stream it seems to be ok.
I'm considering going for the ONE X instead getting sick of the problems with the S.. Shame really as I love the size!
Hard reset and see how it acts after that .
Most of the niggles I had went after I did that.
The S for me is a keeper for a while , screen is great , battery life is amazing . Have you called 3 to see if there's an issue
Got mine today from three. Will report back if I notice anything. Three can slow data down I believe depending on usage on a network. Being in a city might have something to do with it.

Be grateful you get signal. I get jack sh*t in manchester with vodafone haha, always have.
Well I unlocked my bootloader last night, didn't end up putting any ROMs on it but had to start again with my Apps everything was working perfectly when I went to download everything (This is in Sale, about 5 miles from where I work). I even managed some Battle Field 3 online gaming via personal hotspot on my PC.
It was only late on last night I starting having an issue.. was it an app I installed I wonder? I will experiment further.
Shame its networked locked, was going to led it to my friend to try with his Vodfone sim to see how he gets on with it.
Its not the PHONE WOooh! Three have just called, problem with the mast in my area, fixed by the 27th. I can deal with that. And there I was deleting apps etc.

Not to deflate your balloon but I have same prob. I have a fairly good Three signal where I live NE of York. Put the sim out of my One S into Defy+ and I get good signal. Put sim back into One S and back to 1 or 2 bars. I took it back to Three in York but with full signal in York had a hard time explaining my prob. So the assistant typed on the computer ..... guess what she said ....
" problem with the mast in my area, fixed by the end of the week"
Now that is one coincidence is it not? That said even if there was an issue with the 'mast' doesn't explain why the Defy+ has the normal good signal with no signal loss as per One S
Micro sim will work in Defy+ if you place it correctly over the connecting pins!
There are others on here with similar problem
http://forum.xda-developers.com/showthread.php?t=1588345
There is definitely an issue with the current radio firmware as I still have the jumping 3G to H sign but even so at home on the Wirral or in Sale Manchester the internet is spot on, even if it only has 3/4 bars where as in work its full signal but the internet drops out all over the show.
I think it could well be a coincidence that there is an issue with the mast you're on, does the Desire support the faster HSDP+ internet? Maybe its that?
Not sure about the Desire.
I think it's probably the a firmware issue as you say. I know I have a good Three signal where I live as I've tried their PAYG service. Put either the payg or the monthly contract sim, both from Three, in the Defy+ and get a good signal readout. The signal seems to bounce all over. One minute I'm on full bars and the next lost connection. In York where signal is stronger than mine in the sticks there is no issue. Tried with little success to explain the problem to the assitant in Three shop but with full bars on phone she thought I was some sort of fool Mind you when she played the mast card asked why then the Moto Defy+ had no issues with signal
I'm hoping there will be a patch from HTC at some point though they maybe need to be made aware of the issue. I would like to try a T-Mobile sim in the One S but suspect it's locked to Three. I'm sure it's a network provider issue.

Samsung nexus s help

So i dunno if anyone can help me here but ill try anyways. I broke my partners screen on her nexus s so i got a new screen and repaired it. Everything went ok and the phone worked. But it seems the sim card reader was broke also as it wouldnt pick up any sim cards. So i bought a faulty nexus s off ebay so i could replace the sim reader. Now the phone works again but her o2 sim card has very little signal. I tried flashing new radios and this didnt help. I tried downgrading her phone back to 4.0.3 and this didnt work. Sat in the Loft room of my house it gets a signal but 0 bars. An orange sim card gets 2 bars. A vodafone sim card gets 2 bars. So i know the sim card reader works and the phone works but has weak signal. Is there anything else i can try as i cant think of anything. I was going to try flash cm7 and see if that worked but i figured it wouldnt as downgrading to 4.0.3 didnt help so much. Just looked at the phone and it had 1 bar for a second but now has 0 bars again. I can make calls from the loft but anywhere else in the house is a no go. Hope anyone has more knowledge than me and can help. The phone is back on 4.0.4 and using radio Radio KB3 as it couldnt find any network before i flashed this radio. Kinda felt like it didnt upgrade the baseband or something as it said baseband unknown.
first and foremost. Are you sure o2 has a similar signal strength in your house than orange and vodafone?
Is the simcard fitting properly?

Hi mike thanks for replying. Well i took the phone out of the house and it shoud've picked up a better signal. It still had 0 bars although the 3g sign came on. Which it doesnt in my house. And the simcard is definatly fitted correct.

hm, then i guess you cant really download something right? so its not just a display error.
I can just guess along: Was it the exact same component? Does your simcard have any damages? puhh.... xD

I can download via wifi. And yes it was the exact same component i switched out which it why it works abit now just not as good as before i broke it. The sim card is also brand new so it shouldnt be that.

Hi dude. Well i just completely took the phone apart again to check if i missed/broke anything and as far as i can see everything is intact. I dont really know where the antenna is but all the clips are in place and nothing jumped out at me as being broken. Any ideas where the antenna is im guessing it the gold circular thing behing the battery cover with the black thing and a tiny hole in the middle of it.

[Q] gsm loss no call no data

Please help
My S2 plus loses signal, data and no able to call and eferything. After restart ok for couple hours and then again. What can I do?please respond.
Reset to your phone..if that doesn't do the job ,just flash new firmware. If still doesn't work,send back to service center
I would recommend you send to service center.
On second thought,better check whats wrong with ur sim card.i think the problem start from there.pull it out and clean the contact point a bit,or switch other sim
Yeah, it can be the fw. After I had my motherboard replaced it wasn't picking up any signal at all. got at a friends place on the 9th floor to see that it caught 1 operator out of the main ones. Thought they didn't plug the antenna or something, send it back in only to receive it reflashed and nothing else.(the repair course stated something like: no damage fount, reseted settings). Guessing they just flashed England's FW and the bands didn't work well.
I had something like this when i had gsm/wcdma connection type (dunno how to it right in english). Where i live there is poor 3g connection and sometimes when phone loses 3g connection and should switch to 2g it does not and simply says no signal. I switched to gsm only for a while (should get better area coverage later) and i don't lose my signal anymore. If it is crucial to have 3g you can switch on and off airplane mode and you signal will be back, at least it was for me.

3G cell reception issue and fix

I just want to write this post maybe it will help anyone that has or will have the same problem. I looked all over the internet and could not find a fix, so here is my fix. Hope it works.
I work over seas on oil rig sites (remote locations) so I talk to my wife and family back home via different VOIP apps so its important to get a 3G signal, usually I lock WCDMA only network and get at least 1 bar which is sufficient. All of a sudden I started experiencing very weak 3G signal on my phone, weirdly this was at the same location where it had full bars in the past. This only applies for 3G, I could get 2G signal no problem.
In other areas that I know had good 3G signals and towers were close, it would work alright outdoors but once I get behind a door or a window 3G disappears even if I have it locked. I put in my sim card in my old Galaxy Nexus and it had 3G indoors with no problems at the same place and right next to the N5. So I started testing with both phones right next to each other when I lock 3G with the same SIM the Galaxy nexus would get 3 bars while the Nexus 5 would get the empty triangle (emergency calls only).
I couldn't get out of my mind that I dropped my Nexus 5 a hard drop, but I have a rubber case that took all the shock and the phone didn't get a scratch on it. This was before the 3G signal starts getting funny. Couldn't help but feel that I broke it somehow though. I felt like this might have got something loose inside. What didn't make sense to me is that if the antenna didn't work it wouldn't get 3G at all, indoors and outdoors.
So Step 1, I assumed it was a software issue. I went through a painful hard reset. To my surprise it still had the same issue afterwards.
Then out of desperation I saw this dude's video on how he couldn't lock GPS until he opened the back of the phone and found that the GPS antenna was not connecting straight.
youtube com/watch?v=K1-uCIb-t8I[/url]
So I started searching for where the 3G or 2G antennas are on the N5, but couldnt find anything that points that out. The phone was worthless to me like that so... I took a deep breath and decided to open the phone. Keep in mind, i'm an oilfield engineer and I still had a feeling i might [email protected]#k the phone up, specially that I did not have any tools with me.
So I watched this video on how to open up the back cover:
youtube com/watch?v=mkbmtu-1KSQ[/url]
and went through this guide on what's inside the N5:
theregister co uk/2013/11/05/nexus_5_teardown_shows_a_light_touch_thats_easy_to_fix/[/url]
Then I opened it, couldn't find anything to do, except maybe clean the minor dust off and blow on the ICs a bit. There is alot of pins that connect to antennas located on the back cover itself, so I closed it up, made sure its closed tight and all the pins touching, put in my SIM, and GOD DAMN!! IT WORKS AGAIN... I was getting full bars 3G!!!
So what I figured is that when I dropped it, one of those pins moved a little bit away and broke the connection between the antenna and the IC. Works great for the last 5 hours, solid connection.
Hope I would help anyone with this

Thats nice , but lots of ppls have the signal issues with nexus 5 , and it isn't antena disconect for 90 % if us. I have separated the phone many times. , done about 5 hard resets's tried diffrent verions of radio's diffrent ROM's etc... nothing work's. Frineds have nexus 5 2 of them , and they can get 3g and 4g when they want, and i can only get Edge which is 2g. which is unusable..... I noticed that i have 3g only when i am in other towns, but not mine home town.... I tried diffrent sim cards, and diffrent netowrks, nothing seams to get the 3g at home, plus the gsm sucks, it interupts the calls.. So i must be the frequencies of the working 3g network in mine home town ? Then how i don't get 4g ? Why other ppl with the same phone, and same network have 3g when put next to mine ? NO one knows...
Same Issue
i am having the same issue, just having "E" Edge and cannot connect to 3G/4G, done everything to resolve the issue, took apart the antenna part of my phone but all the connectors and wires are intact, did hard reset several times, tried different ROMS including stock ROMS, tried the *#*#4636#*#* selected all the Radios but no luck, used 2 different sim cards but no use, same damn "E" in the status bar, APNs are all in place, nothing is wrong with the settings so far, dont know wots da problem with this set.
Please help us.

Network connection issue

Have my Z5 since before christmas, was working very well till 7 days ago, suddenly dropped from H+ to Edge, then no network, and its been like that most of the time ever since, do a network search, sometimes it finds all the network, sometimes it finds only LTE, most of the time it cannot connect to a network. when I walk outside I can get a connection, but sometimes it cannot make calls, text or data with full signal on H+, for the last 7 days, if I walk outside by 5 feet away from the house I get a signal, walk another 40feet further I have no signal, walk another 30feet further I have a signal, while I have a Z and a s6 both working fine on H+ on the same network, swapping sims made no difference to the z5, and my sim works in all other phones perfect.
anyone experienced this?

only had a few games installed, and word, nothing other than that, phone bought new in December 2015, 1 week after MM, was using Androplus v22 and Romaur v2 phone sitting on charger, with good H+ signal suddenly dropped to edge for less than a minute, then no service. have the S6's and a XZ here sitting side by side, they all work perfect with H+ except the Z5, swapping sims makes no different, but the sim from Z5 working in all other handset, all sim are billpay on same network

First do factory reset if nothing gets better
Take it to service to check antenna

How they are going to replace a phone with unlocked bootloader and with custom kernel?
Did you flash your phone with full firmware and full wipe?

I did, tried 5 different ftf full wipe everytime.
yea bad move for unlocking, certainly wouldn't go with my current provider again, regardless of unlocked bootloader, they have no intention of replacement.
I just checked the antennas they are fine, only thing I see different is with or without the grey antenna wire connected or not, it made no difference to the signal, sub antenna looks perfect and main antenna look perfect too. there's nothing to is just metal contacts.
if the fault is not the board then it be down to software, the phone works in area with good signal, in town and city I get 4g+ and download speed is great, but upload speed still poor, would it be the ic on the board?
PS. the Z5 is much easier to open than anything else I worked on before
maybe a silly question, but should I unlock the simlock first before I unlock the bootloader? this is my second z5, first z5, a week after bootloader unlocked, no network, no sim work in it, no TA backup but it does work in area with strong coverage, even on 4G+ with full signal
bit worry to do anything with the new one now
