Hi all,
Not sure whats relevant so here's the bit. I cannot get any cellular data service on my brand new desire. Phone calls and WiFi have both worked perfectly well.
I ordered a Desire A8182 unlocked from some place in Canada. I then immediately moved to the UK and got a pay as you go service with O2. I also got the data bolt-on. module.. tariff... something. Anyway, there is no cellular data, no icons, nothing to indicate functionality or life out of the cellular data antennae except the mobiles networks menu which says it should be on and working. I bought some vodaphone credit and a tech spent almost an hour trying his best to make it work but with no luck. He referred me to here. I'm beginning to worry this phone I bought may be damaged, maybe not physically but possibly corrupted firmware? Is there anyway to tell what is the problem with my phone?
thanks ahead

Hey guys,
I'm with Vodafone UK (notorious for their bad signal coverage) but this morning when I woke up, my HOX has had absolutely no signal.
I've tried everything I can think of to resolve the issues, standard restart, hard restart, removing the sim card etc. but to no avail.
I also wondered if it was maybe Vodafone having a bad day too and asked my friends who are also with them, if they had any signal. They all have full signal.
Then i checked the settings on my device, phone identity.
For some reason, the IMEI, IMEI SV, IMSI and phone number are now all unknown. I'm not really sure what this means, but I know they normally have something underneath them.
This has led me to believe its an issue with my sim card/contract whatever... maybe I haven't paid my contract so Vodafone cut me off, went online and checked. Everything has been paid for.
Got any suggestions as to whats wrong and how I can resolve this please?
Hi,
I had a similar problem (also on Vodafone, but it may just be coincidental). I had no signal for a couple of days and thought it was due to a screw up during my number porting from O2.
Anyway, after 2 days of calling customer services and having my SIM swapped twice I went into the store and they replaced my phone. It's fine now.
Funny enough I also woke up to phone having zero signal, but am with o2. After 1min or even less signal came back.
just got off the phone to the Vodafone people.
After trying my sim card in my friends Vodafone HOX (black), I got signal. This has led me to believe its a hardware issue, but despite this the phonerep still insisted it might be a software issue (I have the latest OTA update, same as my friend and his is fine? NB: his device doesnt have the flicker issue unlike mine).
Will have to visit the local store to have the shop monkey tell me the dreaded, "we'll have to send it away for repair" probably. If this is the case, the phonerep said I would probably have to pay for any repairs/new handset as I dont have insurance. Is that fair because I'm still well within warranty..?
Sounds about right, if you within your 28 days you can ask for a replacement. As per rules. Even HTC say to replace. Anything after 28 days needs to be sent to HTC for repair. You shouldn't have to pay for any repairs it should be covered under warranty. They can refuse or charge if you have tampered with it, as in did the HTC unlock and installed a custom rom.
See what the shop says, if HTC do charge then kick up a big fuss.
No issues with my vodafone sim in mine, however had terrible issues with GG, kept losing sim card I assumed it was a faulty sim card causing the issues.
Hey there, my girlfriend is on Vodafone with an iPhone 4S, she lost her signal yesterday morning and still hasn't had it back bar a five minute window this afternoon. she lives near a place called Devizes (its in Wiltshire) but her mum had it back from last night, I don't know anyone else on Vodafone so I don't know how far it has spread.
Edited to add: you can check for reported signal/mast issues here (http://forum.vodafone.co.uk/t5/Faults-Board/bd-p/69) the bit on the right of the first set of numbers in the thread title is the start of the postcode for the area the mast is based.
Think I'm a few days past the 28 days, just my luck! And I haven't done anything to the phone whatsoever, everything is stock.
More evidence that something's gone wrong... After leaving it on charge all night (as per), the battery has dropped from 100% to 14% in the space of 4 hours with just some casual wifi usage. It's also extremely quick to heat up now, and thats just from leaving it on charge.
If they make me pay for a blatant hardware issue I will kick up a massive fuss. Why should I pay to have the manufacturer fix a phone that has clearly been made to an unsatisfactory level?
Updated to the latest firmware, and still having data loss issues. I fixed the APN, and restarted the device and it works fine for a bit, but a day or two goes buy and I have to restart the device again. We've even got another one from AT&T.
Anybody else having this issue?
Same here
Hey, I have been having the same issues since day 1, I havent tried to replace or return my phone because I bought it from an ebay seller and I am living in Ecuador, so its kind of expensive just to try to send it back and possibly with no response or telling me that is a network issue of my country.
Each time I go to a place with a weak signal, the phone will go to "E", and the connection wil drop, after a few minutes return to "4G", but the connection won't return at all, the only way to restore the connection is by rebooting.
By the way, I have done like 10 hard resets, and even reloaded the firmware with nokia care suite, and nothing, the problem persists.
My wife is using a Lumia 710, and it works perfectly.
You are the first person in all the web, I have found that has still has this issue
I am using an unlocked lumia 900 from rogers
Recently i have purchased a used Verizon Galaxy Nexus from a seller on ebay. It is in excellent shape and has no cosmetic damage to the phone. The persone i purchased it from was a reputable seller and had the feedback to back it up. Now with that said. The phone was listed as broken because the seller could not get the phone to connect to the Verizon cell network.
So i bought the phone thinking that maybe the phone had some deleted files on it that i could replace or better yet. Just flash all new software to the phone and remedy the problem. Thus i would have bought a phone for a quarter the price of a new one and have a fully functioning phone.
As far as flashing and roming goes. I am no novice. I have owned many Android phones, in fact thats all ive owned lol, but this one is causing me some frustration. So here is a list of the things i have done to remedy the problem to no avail...
1) Factory Reset- no go
2) Complete Re-Flash of the entire framework - Im talking everything. Careful fastboot flash of every elemet of the android ecosystem
3) Radio swapps from older versions to newer versions.
4) Multiple reboots and toggleing airplane mode over and over again.
5) Flashed several aftermarket roms.
6) Toggled the test mode in phone settings using the hidden menu (*#*#4636#*#*)
For a short period of time last night i was able to get the phone to display up to 3 bars of service using the method described in #6 I NEVER got data working and i could only temporarily call out. My girlfriend would see me calling in on her phone but immediately upon answering it would drop my call. The phone never rang on my end and it cannot receive calls. Also cannot send text messages.
I thought for sure i could fix this one, but for some reason it is being stubborn. Please Help me XDA!!! Your my only Hope!!!
P.S. As an aside i did take the phone apart and check to make sure nothing was damaged. All the components look top shape and all the little snap connectors are securely fastened. No metal contact prongs are bent and everything is clean of dirt and debris.
does it display your IMEI *#06#?
maybe some NV_DATA corrupted or it can be hardware issue
Does indeed show imei and I had it checked for lost / stolen / blacklist by Verizon. At the store now to get it checked out.
And that is actually meid that that code pulls.

And the verizon store could not do any good. Has anyone ever ordered a replacement back casing from ebay or anywhere else on the web? Im thinking it may be a ribbon cable somewhere. Maybe even the bottom board that houses the headphone jack and a series of winding antenna leads.
I am still open to suggestion though so anyone with any information on the matter please let me know.
EDIT: Been looking at Cell phone repair shop and they have the antenna / headphone replacement in stock. They also have the back mid frame with all the antennas on it as well.
I feel like this is a 50/50 shot in the dark as to which part i need to fix this problem. Gonna give them a call tomorrow and see.
I've ordered a new mid frame in the hopes that there is a torn ribbon cable somewhere in the old one. I'm still not certain that's what it is though.
Anyone with some insight please get back to me.

I've been all through the device and checked all the connections and hardware. Everything has a firm connection and is in top shape. I even replaced the back midframe cover with a brand spanking new (OEM Samsung) one. Its behaving like a software problem in that I can toggle between 3G and 4G and get 3G for a brief moment and can even call out, but the moment that someone answers the call it drops service and i have to start the process all over again.

I've done this as well several times. 4.2.2 and 4.2.1 and yes i made sure i had the correct firmware for my version of the phone. Verizon toro.
Edit: Has anyone ever sent in their phone to Samsung for RMA? I called and talked to someone and tried to work through the problem and she came to the conclusion that I should send it in at no cost and that I wouldn't be charged anything unless I authorized them payment before. Essentially they will run through the phone and check everything out for free and see if it can be fixed.

I did the same thing. Bought one from ebay in good shape. Was told it functions. I have the HTC Rezound so the sim wouldnt fit. Went to Verizon and they put in the mini sim and no service. Reset the phone and even tried a new sim. I have since tried different roms and radios, but still no service. Luckily the seller has a 100% guarantee so looks like this one is going back. From what I have read, these are prone to radio issues.

Yeah. I've read multiple threads about radio issues, but here's the thing. Every one of them claiming to have signal issues also had the random reboot issue. They all were even having problems flashing any Roms or anything else for that matter.
I on the other hand have had zero problems flashing anything. Fastboot works 100%, Recovery flash works 100% and I can unlock and lock the boot loader without issue. Its an odd problem.

I've had an issue flashing, it would abort for no reason. I would also have issues getting into CWM. After playing around with it all night, I don't think its a software issue. I've been reading the antenna has given other people issues and some have even tried to replace them. a Rep from Verizon thought it was the sim reader. I don't believe that because the phone registers a sim and the number tied to it (which is my number). Under status, I does read different every time.
Network: searching for service
Signal strength is usually at: -120dBm 99asu
Mobile network type: (varies) CDMA - 1xRTT:7 or LTE: 13 or unavailable
Service state: out of service
Roaming: not roaming
Mobile network state: (varies) Disconnected or Connected
I've tried different combos such as CDMA and Home LTE Automatic and so on. I think its just a poor design. Seems to be only the CDMA devices tho.
Did OP ever arrive at a solution or at least pinpoint the cause of this problem? I am currently experiencing a pretty much identical problem to the one described (with the exception that I don't even get a 3G signal -- complete lack of signal). My problem started after a brief Airplane mode toggle yesterday and I haven't been able to get on the network since.
Thanks.
I think it's a hardware problem tbh.
I modded mine to work with the palm pre touchstone inductive charging kit. In the process wires were soldered, rear housings were mutilated and the phone was tortured a bit. I was never happy with Samsung's **** build quality so I eventually just ditched it altogether.
I decided to repair it and give it to a family member so I replaced the back housing and USB port with parts ordered off ebay. Ever since my repair work the thing cosmetically looks almost mint. However no OS will recognize it anymore (windows throws an "invalid descriptor" and won't install a driver) and 3G/4G/wifi reception is almost nonexistent. Switching roms or radios doesn't seem to help, and obviously I can't odin a factory image. Pretty much boned.

Had a similar problem in regards to a lack of signal. It just completely gave out while driving a couple days ago (interestingly enough, the music I was streaming via Soundcloud stopped right as I passed the Facebook headquarters in Menlo Park, which ironically is a 4G dead zone for Verizon). This was a refurbished replacement device that I got about 15 months ago, and was running the latest OmniMetal rom flawlessly for the last few months.
I arrived at this thread and followed all the steps that OP took to try and fix it. Ended up reverting to an earlier 4.2.2 rom and reflashed the radios thinking that might solve the problem. Upon reboot was able to connect to mobile data and make phone calls briefly, but about an hour later the same thing happened. Brought it to the store and swapped out the SIM card for a new one, no dice.
Fortunately VZW is doing open enrolment for phone insurance, so I added it for $10/month to get an extended warranty. Now I'm going to restore everything to stock, lock the bootloader and send it back for a new one. Assuming there are no problems with the replacement, I can cancel the insurance plan, bringing the cost of the replacement Gnex to just 10 bucks.
Was anyone out there able to successfully modify the radio hardware for cheap?

I did the same mod, and other than losing my pc connection (which frankly is never needed) it's been great. You have to be very careful and take your time. I'm not even convinced that my pc connection issues are related to the Palm mod, I think they just happened to coincide. Either way, I don't need it so I never bothered tracing it down.
Hey,
since a few days, I'm not able to access 3G/LTE anymore in Germany with European G4 H815. Bootloader is unlocked (so no warranty for me).
I already reflashed it with KDZ with CSE flash, also tried to enable/reflash LTE Bands described here:
http://forum.xda-developers.com/g4/general/guide-enabling-lte-bands-t3137818
2G/GSM/Edge is possible, not more. Forcing the network to use 3G only results in no connection to the network.
Tried also swapping SIM cards with my GFs smartphone, her SIM card can also only get GSM in my G4, my SIM card can easily get H+ on her smartphone.
May this be a defective modem, or maybe a software bug? I flashed Genisys Rom, now back to stock.
Help would be greatly appreciated! Any thoughts?
Kind regards
Have you tried erasing and then adding in a new APN? If it worked prior this would be a good starting place
Thanks for the answer! Yes, I tried any possible APN configuration.
On my wife's h815 I can't test this as access is denied, but your on genisys ROM so it may let you
Open the dialer and type
*#*#4636#*#*
Hey,
I tried it, but could not click Phone Info. Error message is:
This application does not work on this device.
When I first rooted the G4, I backuped all system partitions. Maybe I should try to revert them all? I already tried to restore MODEM, MODEMST1 and MODEMST2.
Or could this be dangerous?
Kind regards
Yeah same with my wife's phone, it's strange were locked out there..
Restoring those partitions shouldn't hurt anything but I'm not very familiar with this phone so can't attest to anything for sure and the wife is on holiday so I can't check her phone
When you went through apns, did you try to first erase them all completely? If not try that, then make a new one
Yeah, I've got only one APN. I also requested a new one by my provider via SMS.
I wonder if the modem itself is defective. Maybe it got fried by wireless charging, I'm using a chinese Qi-Sticker and replaced the original one.
Are you using wireless charging?
No, just a cheap dock, but as far as I know that won't fry the internals or interfere with the radio at all
The reason I keep asking if you fully erased all apns and start over is I had to do this with a 2013 motox when it switched to lollipop, for some reason all apns had to be erased and then readded to get lte/3g to work again, the phone was stuck on edge just like yours
Okay, I found out by chance today, that there is 3G/HSPA reception possible. I was standing outside 100m away from a cell tower, and had medium reception. Maybe there is a problem with the internal antenna?
Oh, and by the way, I can see LTE network here at home (but no HSPA), but don't have a LTE contract, so I can't connect to it.
Maybe next time, when you are next to a cell tower, you try it yourself?
I haven't found a solution.
LG refuses to repair to my G4 for free, but I buyed the phone at Amazon (De). I called the hotline, they cover the warranty for 2 years, so today I sent the phone in for repair.
I'll keep you updated if Amazon repairs it despite the bootloader being unlocked (I told them before).
Sorry I couldn't offer a technical solution for anyone with the same problem
This is what happened in the meantime:
I sent the phone to an Amazon Partner Service Center. They refused to repair it under warranty - Bootloader unlocked. They offered me to replace the motherboard with a new one - 283€ incl shipping
After that offer, I called Amazon that their partner would not repair the phone under warranty.
They then sent me a brand new G4 for free! After I already had received the new unit from Amazon, of course I had to send back the defective G4 (when it came 10 days later from the repair service).
My friend has exactly the same problem.
Bootloader is unlocked. Tried to go back to stock MM 20c firmware from Imperium v1 Rom, but that didn't work. Also no update to 20d is offered by LG. If i force to use 3G, the phone can't connect to the cell network. Only edge does work. APN looks also good. Furthermore i tried to flash a new/other modem, but that didn't work also :/
Does someone have any suggestions to fix this problem?
@t000x: Was unlocked bootloader and therefore no warranty no problem for amazon.de?
Hi hasenbolle,
try restoring the firmware first, before shipping it back:
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
Yes, Amazon gave me a new unit despite the bootloader being unlocked.
But first I had to send it to their partner service Center and wait a few days.
Good luck with that phone.
