[Q] N4 - No 3G signal - at all - Nexus 4 Q&A, Help & Troubleshooting

Hey everyone,
first post here. Been hopping over to a N4 I snagged from eBay just recently from a Razr I.
Solid phone, one thing that friggs the hell out of me, I cannot get 3g/H/H+ to work, been turning the internet upside down, the only things so far that I didn't try are flashing a different radio or ROM...
Device Info:
Nexus 4 - 16GB black
Running Stock 4.4.4 Build KTU84P (rooted with towel...)
Kernel 3.4.0 (stock?)
No custom recovery, no fancy rom experiments yet.
As long as I prefer Edge, I have full reception. Once I switch out to WCDMA, the device gives me the finger. No signal. No phone calls possible. No data connection.
SIM card is okay, came directly out of the rI working fine. Tested the card in my wifes phone, checked her sim in mine, all no change. I've been doing the *#*#4636#*#* thing, didn't help either.
Yelled at my providers support (o2 Germany) for about an hour because they claim it's the device. Been in contact with the seller, he claims it was working with o2 and t-mobile.
I'm all out of ideas. Google, and the forum search didn't help either.

APN settings?

Here you go.
-Edith says: They were crosschecked with o2.de website. And they match. Automatic configuration fails with 'Device not compatible'

Flash full factory image and report back. In your situation though I'd probably return the device. It's definitely not your apn settings (you would still get signal). It clearly is the device too, as the sim works fine in another phone.

actually, it Seems to be the Provider in question.
After a lengthy and 'friendly' Chat with their mobile data Team They some what admitted to have issues with the n4 and n5 in particular, which stem from frequency Problems...
Contract is overdue for cancellation anyways... T-mobile has some pretty nice Plans either...

Have you tried a SIM from another provider? There shouldn't be any oddities with frequency for the nexus 4 as it is the same device all around the world with support for most countries.

Interesting "Glitch"? Att on HD2 showing as "G" now after radio update and NRG.

Interesting "Glitch"? Att on HD2 showing as "G" now after radio update and NRG.
Hey all thought I would post this for you all.

What did I do? Well I just updated to July 30th of NRG rom for the Leo. Also upgraded from 2.08 to 2.12.50.02_2 radio rom. after the reboot.. it changed from E (Like it normally had) to the G which I know isnt the normal 3G icon, but that its showing up as G period is making me wonder if this is a glitch where nothing comes of it.. or if this could be something more that happened unexpectedly.
Who knows.. maybe Att can use 3g on the hd2 sometime
so, that'l be G for GPRS then, , , not 3g.
Well Ive seen my G1 do that on Tmobile too.. Where when it is on Edge, then it goes G, then finally into its 3G icon. So are you saying that the G is only meaning GPRS? Cause if thats so, then that one is new to me.. (havent seen a G since my Nokia s60 days, pre edge)
But still its a odd change that forever I had E up there, now its G, which if its GPRS, that means its even worse off with that radio.
i get G all the time, office is in the cellar, E upstairs, G downstairs. (I have 3g turned off)
What exactly are you trying to ask? Are you curious to know what the "G" stands for or are you questioned whether you'll get AT&T 3G on a tmoUS HD2?
G means it's on GPRS, worse than Edge. If it's staying at a constant G, then it means you're in a crappy zone or the band setting of the new radio is not set correctly.
And just in case it's lingering in the back of your mind, the answer is no. You will never see the AT&T "3G" or even "H" on your TmoUS HD2. Period.
Yea guess I didnt think about GPRS, was late when I posted. Didnt even think of it. Been ages since I even used gprs lol.
But yea, then that might indeed mean that HD2 unlocked on ATT that the 2.12 radio rom sucks. =/ (Least for ATT)

[Q] Bluetooth & Wi-Fi issue on ROM 1.72, what to do

My previous HD2 had a 1.66 ROM and had no issues with Wi-Fi or bluetooth. My current HD2 has a 1.72 ROM and I can't get the phone to find any Wi-Fi network or any bluetooth device. The software simply doesn't find any and returns after a time out. I was able to pair another phone to the HD2 by changing its visibility to visible so bluetooth communication does seem to work. I have no issues making data connections and phone calls. What could I do to find the problem? What can I test?
ROM 1.72.172.0 (82429.0)
Radio 2.07.51.22_2
OS 5.2.21869 (21869.5.0.82)
Does this problem ring a bell for anyone? Would installing a custom ROM help? I read some bad things about the radio version 2.07 I'm currently using.
Silly question, but why did you change from 1.66 to 1.72. It is not an updated version of 1.66, it is just the operator branding (bloatware?) of 1.66.
Is it the same Radio ROM as you had in the problem free 1.66?
No this is a different HD2. My first one was stolen. This is a new one. Well actually a repaired one I bought second hand. I didn't change anything to it (yet). I'll happily experiment with different roms and radios if that can solve the problem but I'd like your opnions on this.
Edit
Just talked to a HTC rep. He advices to install the latest ROM and pointed me out to the 1.66 ROM on their website. I tried but can't download that one because my phone is a VF branded one and the website won't accept my serial number. I'll try the 1.72 ROM from their website but I don't expect any difference. If that doesn't solve the problem I guess I'll try a custom ROM.
Re-flashing the stock VF ROM didn't help. Neither did flashing a custom ROM. But when I took the battery cover off the HD2 I discovered that it functions as an antenna of some sort. The are 2 connection spots that are bare metal:

}
Then I discovered that 1 of the 2 pins that are supposed to make contact with these spots didn't protrude out of the body of the HD2 and wasn't making contact with the battery cover / antenna.
The good pin:
The bad pin:
This probably is the reason for the malfunctioning bluetooth and WiFi. I re-flashed the stock ROM and wil be bringing HD2 back to the VF store for repair today. To be continued.
Can´t be. I use the ext. batt and this has a plastic cover w/o contacts and my 1.66-ROM is running perfect. Antennae are NOT in batt.cover !!! nor connected to batt.cover
I also had problems when flashed radios higher tha. 2.06.51.07 (for android-install). Reverted back to radio 2.06 and everything is fine again.

What problems did you have?
And I hadn't noticed the 2 pins before on my previous HD2. Does your HD2 have them?
I always thought the back panel was for a future inductive charging system.
I got my HD2 back from the repair shop yesterday. They found a 'mechanical' failure and repaired it. Detecting bluetooth devices and wifi networks now works perfectly.
The pin on the back of the phone still isn't touching the back panel though. But this doesn't seem to affect the reception.

Xperia SP faulty wifi indicator + wrong wifi indication

Hi all,
This morning I was investigating the common wifi issue on our phones. We all know some devices have this issue.
I did a small research with the app Wifi Analyzer and I found this small "bug"..
In systemUI (statusbar) you have the indictors for wifi, nfc, bluetooth, mobile network, time.
When you connect to wifi you get an ammount of bars. I discoverd the following:
(please focus on the statusbar)
Both phones use 4 bars (dot included) to indicate the wificonnection
First picture is from my Samsung Galaxy S Plus Running latest Stock Gingerbread 2.3.6

The second picture is from Xperia SP running latest stock 12.0.A.2.254 (non rooted)
BOTH PHONES WERE ON THE TABLE APROX 2 METER FROM OUR WIRELESS ROUTER!
For some unknow reason the indictator tells a diffrent story than the app Wifi Analyzer..
To be honest i think we all get fooled here. Both phones are having (in my case) a decent but not perfect connection and my Sony still thinks it is a crappy one. ( The option avoid bad connections is off in my case)
So perhaps this is also a bug in Sony roms?
Regards

From what I've read in the past, there is no industry standard to what "one bar" actually means.
That is for the phone network signal though.
I assume there is no standard for Wi-Fi bars either

Which is my conclusion here. When you see only the dot in your status bar. It does not mean it is a crappy connection
It shows that xperia sp wifi cannot catch the signals properly... maybe

Note 3 reception and wifi

i know this has been mentioned before but i cant believe the difference can be this much. i have an s4 and a note 3. i did side by side speedetest's same server, same time (10 times btw) and the results are the same. the s4 is almost 3 times faster. Also i did go in to the service menu and make sure wifi power saving was enabled in both and then disabled, no change. (*#0011# menu key the select wifi to see wifi). i have noticed a difference in reception as well. not as significant but the s4 is always 10-13 db better and gets into lte much faster. fast dormace is enabled on both phones as it is supported by Telus here in canada. any thoughts guys? i ve attached a pic but i can upload a video as well, excuse the quality i had to use my tablet
thank u
looks like i am joining the club.
on three uk 3g sppeds MUCH better on s4 than on note and wifi speeds better on s4 and keeps disconnecting and buggy on N3 compared to s4 and any of my older phones even obsolete old phones like the HTC desire! Hope samsung cant sort this out with updates or have an expensive brick.
Same results here, N3 does half the wifi throughput then my other devices.
Probably what you're all experiencing is Wifi dropouts. It was bogging my internet down on the Note 3. Router was to blame, or really Samsung's chosen Wifi chipset. Either wait for Samsung to fix it or tryout another router model, which will be hit-and-miss unless through people here or at friends, hotspots etc. you bump into a good one.
This will probably be fixed in a future update...
I got 3 rom updates since I bought my device... And the last one fixed the speed problem on wifi... I'm getting the full speed now (60 down and 10 up with Vidéotron) connected to a wifi AC router.

Ever since Lollipop, multiple devices called "connectsdk" show up on my network.

Ever since Lollipop, multiple devices called "connectsdk" show up on my network.
So this is kind of strange. I went into my router to check on something, and noticed a bunch of mystery devices connected to my network all named "connectsdk". One of them is my phone. Each "device" has its own IP. This is new ever since the 5.0.2 Lollipop update on my G2. I googled "connectsdk" and it is indeed an LG thing.

Now .. this is interesting to me, because ever since the Lollipop update, I have been having terrible battery life and my phone heats up for no apparent reason (Verizon VS980). And this seems to be much worse when I am away from a strong Wifi signal. So naturally I put two and two together, and it has me wondering if these mystery "devices" connected to my router might be causing the atrocious battery life and heat problems. As if maybe they are all searching for signal or probing hotspots at once.
I am assuming that ConnectSDK in this case is something embedded into an LG system app.. and my question is, which one? If I can disable whatever is doing this, I might be able to fix the battery problems.
Any clue what is causing these devices to show up on my network? Any way I can trace the IPs back to whatever system service/app is making these connections? Can any of you guys check your routers and see if these show up for you?
Thanks :good:
I'm seeing connectsdk too but I have a s6. I also have a wrt1900ac.
I have these too: a connectsdk, and a connectsdk-1.
My DHCP detailed list (available in advanced network settings, may be a little different for different routers) says that the connectsdk-1 has the same wireless MAC address as my 10inch Samsung Android Tablet, and the connectsdk says it's connected to the same wireless MAC address as my Samsung Galaxy Nexus Android Phone.
I still don't know what the purpose of these connectSDKs are, but I assume they are legit connections. I was worried at first though, seeing strange things connected to my router. And I don't think these showed up with earlier router firmware.
My connectsdk was my Nexus 7 (2013) Tablet.
