Hi everyone. Just to start out, I am completely new to the Android world – I’ve tried to read up on these forums and whatnot but I am definitely a noob. I am coming from Apple, and long story short, I’m tired of iPhones and got myself a Galaxy S3 via Swappa in order to keep my unlimited data plan. It was previously rooted, but I requested that it be restored to stock.
I have been unable to get to a Verizon corporate store to get a sim card and activate the phone, so I’ve been using it on wifi around the house. I am having signal issues with the wif – it works everywhere except in my room. The signal shows as weak and keeps dropping every few minutes. My other devices have a strong signal. I have downloaded various wifi analyzer apps from the Play store, and they all show the wifi signal as really weak.
I searched and found numerous threads that this is an issue with some of the phones. I tried messing with settings (factory reset the phone, the router, did the *#0011# and turned wifi power saving off, changed the "keep wifi on during sleep" from always to never, etc) and nothing fixes it.
I would like to know what you guys recommend. Should I go ahead get a sim, activate the phone, update to Jelly Bean and see if that fixes the issue? I am unable to get the update since I do not have service. I tried to update via Kies, but it says current firmware pda:lg1 phone: lg1 csc: lg1 (vzw) not supported.
Or should I tell Verizon about the problem and see if they will go ahead and replace the phone? I’m not sure how that works since I am not the original owner. I’ve read that they honor the warranty based on the purchase date which is tied to the IMEI number, and not the owner’s name. Not sure how true that is… Also on the box, it says Verizon 4G LTE Certified. Not sure if that means my phone is already a certified replacement or if all the boxes say that. I haven’t been able to find that out.
I’ve read the thread about resetting the phone to return to Verizon. The flash counter screen reads Odin mode, product name: SCH-I535, Custom Binary Download: No, Current Binary: Samsung Official, System Status: Official, Qualcomm Secureboot: Enable. The android version is 4.0.4 and the baseband is I535VRLG1. Does it matter what the kernel, build number and hardware version are? I’m not sure what they should be.
I just want to be prepared when I walk into the Verizon store (which is unfortunately over an hour away), so I’m hoping I can get some opinions and maybe save myself multiple trips. I’m not sure if Verizon will work with me or not, but I figured you guys are the experts and can help me out. Thank you!
It looks like the guy who sold you the phone did in fact fully return you to stock. But it is fully stock based on the oldest stock firmware (I535VRLG1). My advice to you would be to activate the phone, and grab the OTA updates all the way up until the current version (I535VRBLK3).
I used to have all kinds of WiFi connectivity issues with this phone, until I replaced my router. Now it works perfectly. There was no real explanation as to why that was, but this phone does seem to have WiFi connectivity issues, especially with older Routers.
Try updating your software first, and see if the problem resolves with the new firmware. I believe Verizon does base the warranty off of the phone activation date, at least they did years ago in the past, but that may have changed.
Thank you, I appreciate the reply. I read that there was an OTA update issued around October to fix some of the wifi issues, but I wasn't sure if I had it. Once I activate the phone with the sim, do you think there will be any issues receiving the updates? I know nothing about rooting and have been trying to read more about it, but I'm concerned I'll end up causing more problems with the phone before I even get to use it.
The router I have is a free one Verizon gives to use with their dsl service - a Westell Model 327w. It is pretty old, although I think the firmware is up to date. The phone works fine when it is closer to the router and everywhere else in my house, except my room which is upstairs and at the other end of the house. I just figured since my other devices work fine, the S3 should too.
Thanks again.
If you are fully stock, with the stock recovery (which it sounds like you probably are), you should have no problem downloading and installing the OTAs. I believe you will have to take a few them before you get up to the current version.
I can confirm that the stock Verizon GSIII has a few upgrades before you get to 4.1.1 (the latest version)
Thanks guys.
I just remembered that I have a newer router that Verizon sent me, but I never bothered with it because the current one was working. I'll try and set that up and see if the signal improves.
I am hoping to get to the Verizon store soon, but unfortunately things keep happening that prevent me from making the trip. Can't wait to get this phone working though. Just the little bit I've played with it makes it difficult for me to go back to my iPhone.
This is how a noob post should read. Nice job, OP -- very informative and you did some homework.
Other noobs take notice -- this is how you do it. Notice how much help he got?

If its any consolation, I had wi-fi issues even with a newer Verizon router all the way up to the latest version of the the modem and rpm file (vblk3). With the last and latest (vblk3) update, those problems disappeared. So as stated, I would update the software to the latest and hopefully you should be good. Just to add, my wife had the same problems (same phone) as well so this validates for me that it was a software issue.
Hi everyone.
I owned a Nexus 5 one month ago, but unfortunately, it does not work as expected. On 4.4.0, I had multiple issues concerning network already (unable to switch to 3G networks only, very variable HSPA signal reception (from 4/4 bars to Edge exactly at the same place), ...). This issues were supposed to be fixed with 4.4.2 and most of them are, excepting HSPA signal which is still very weird. However 4.2.2 brings my phone another issue that I didn't noticed on 4.4.0 which is a very annoying and repetitive complete signal blackout (no reception at all (Edge/HSPA), even for emergency calls I guess). Signal drop can happen twice in an hour, twice in 10 minutes or may not happen at all 3-4-5 hours long. It's completely unpredictable. After a while, Edge signal (not HSPA !!) gets back by itself. If I wait 10-20 more minutes, HSPA comes back again, until it drops again.
Moreover, at phone boot, just after typing my PIN Code, it usually takes 2 or 3 minutes to catch a signal. Very slow isn't it ?
It does not seem to be a network issue, since my Samsung Galaxy S III doesn't encounter this using the same SIM card.
I read on Google forums and probably some XDA threads that I was not the only one to face this kind of network issues, even on 4.4.2, but issue description was each time a bit different from mine, thus I tought that it may be useful to post a new thread to describe precisely what was my problem.
Edit : My Nexus 5 is unlocked and rooted, but issue is present on untouched 4.2.2 also.
Edit 2 : http://forum.xda-developers.com/showthread.php?t=2525583 is probably my issue.
Do no hesitate to answer if you're thinking that you have the same issue (or kind of) or if you think that you know something that may help.
Thank you .

You can flash the radio from version 4.4 that helps a lot, I'm at work just search this forum the directions are here, it's easy.

^^ He appears to be talking about the link below. You can flash different modems that may work. Some people say different modems helped but I've had no such luck. I've flashed every modem available and still don't have data almost everywhere I go. I have data at home but that doesn't really matter since I don't need my phone at home.

Did you try flashing your carrier's specific radio?
Team Nexus 5 sucks

Were would one find the carrier specific radio? I'm on T-Mobile but have only found the thread with modems. Nothing carrier specific.
Thanks for your answers. Unfortunately, flashing different modems does not seem to help .
i've read, the .15 is good with t-mobile.
i'm testing it today too. my problem is not only a signal drop, i have only edge too and my modem won't switch back to umts or hspa(+).
i'm in germany with t-mobile (congstar).
Hello everyone,
I would like to share big problem what I have and killing me.
Sometimes (1 time in a day or 1 time in 2 days), GSM signal is lost and I have to restart my nexus. What I have done so far,
* I checked my IMEI number and that's OK
* I checked my sim card againts to damages and scratches and that's OK. But these is gap between sim tray and card by ~1mm. The gap is only on long side of tray, short side is fully matched.
* I checked signal power and asked to carrier (TR AVEA) and that's OK.
* I installed hidden menus from Google Play then go to setting -> testing menu -> Phone Info
- preferred mode : GSM auto (PRL)
- If I select "select radia band" from pull-down menu, only one possibilities "USA Band". Even If select this, GSM and data signal loss.
- I tried another carrier sim card (Vodafone TR) and applied same settings above (USA Band), and failed again.
- I understand that "USA Band" is not suitable for us
My device is D821(E) and use 4.4.3 full stock firmware. No root, locked.
Can anyone help me? Thank.
After I updated to 4.4.3 (via purity ROM and Flashing the new Radio/Baseband) I noticed my data connection was constantly droppping in and out
So today I decided to flash the old radio from KRT16M (4.4.2) to see if it made a difference and it seems to have so far. I haven't had any loss of connection in the 2hrs since flashing, whereas on the new radio it was constantly dropping in and out. I will test for longer but i think the new radio in 4.4.3 may not be optimised for some networks (i'm on Optus in Australia)

2 months ago, someone from Turkey who use same carrier (TR AVEA) has noticed signal loss problem with 4.4.2
I remember that he has mentioned neither stock and customs has same problems. I think this is completely baseband problem.

Also had to revert to 4.4.2 radio wasn't receiving incoming calls with the 4.4.3,don't think it really matters which you use though

I had same problem. Devs seem to think radios are the same for both phones. If they are why are there different models for usa and Europe? If you put a usa radio in uk phone it will work poorly as it has SOME bands and vice versa i found one marked d21 radio and back to normal. You are treated as a moron for thinking that the radios differ. Look at Wikipedia

Can you please share the name of baseband that you found?
And I checked the wikipedia and could not find any useful things as you said.
This is a photograph of the baseband I put in and another of the different frequencys the two phones use. Using D20 in uk drastically affects h+ as you will see by the difference
# 47386
Here
# 47386
On lte , which includes h+on most, you can see the d20 radio is usless in the UK i was getting h at best and 3g most. Now im back to h+all the time. The experts say that there is no difference so take your pick.
# 47386
Same baseband that I use with 4.4.3 OTA.
I always use 3G "Preferred Network" option.
Same problem here with the new 4.4.3 radio. Incredibly weak LTE signal (fine if I select 3G in Mobile Networks) and sometimes no signal at all. I may try flashing the older radio this evening.
I realised it was happening more often when my gps was locked.. As soon as i switched off gps my signal restored..
Running rooted 4.4.3 stock rom

I'm still having some issues with the older radio, not as many as with the new, so there may be something inherent in the 4.4.3 update as well, this is annoying as my phone was running perfect on 4.4.2, may have to restore my backup
Really nice phone and cool design.
But weird problems without solution

Guessing from the last line, you had updated to 4.4.3 through OTA? You could try to reflash the radio img but that would require you to has custom recovery.

That's because flashing different modem images (D280/D281) does not change your available phone bands. It is a hardware limitation, nothing to do with with firmware.
That was not on my phone. I put it on. As you can see in the pic above there is a world of difference between the two models. Depending on where you are if you get a d20 radio in a d21 your going to get no data like i did
# 47386
As far as I know, it depends on your network capabilities. I have a D281 running the latest D280 radio, everything works as fine. Faster LTE even.
am not sure what is wrong too but am facing this issue quite a lot as well. But it is not restricted to Nexus 5 only. I have another phone Samsung Galaxy Grand 2 and face the same issue.
Am not sure what to do on this, however, after some search I found a site where the author claims it gets fixed after uninstalling updates of the following apps:
Google Launcher
Google Search
Google Maps
Google Hangouts
Google Newstand
One or more amongst the apps might be causing some issues. See if it fixes your problems. I will be trying it too but will uninstall all updates from one of the above applications at a time to see which app is the real culprit. Please share with all of us in case you get to know before me or have another solution for us to try.
PS: Hit 'Thank You;' if this helps.
Hello everyone. I was hoping that some of you that are more knowledgeable about this stuff could help me out here. I recently flashed from CM 10.2 to KitKat (4.4.4), which everything went smoothly for the most part. However, I've noticed that my phone constantly has no service. I should probably state that I live in an area with very low service to begin with, but prior to the flash I was able to get at least a bar inside my house. Now, I'm unable to get anything.
The first thing I could think of to check was my settings in the phone. The data is enabled, CDMA Roaming mode is set to automatic, CDMA subscription is set to RUIM / SIM, and the Preferred Network Type was Global. I wasn't familiar with the global setting as I was used to seeing the LTE / CDMA / EvDo options there. So, when I clicked on it, it now gives LTE, 3g, 2g, 1x, and Global as options. I tried changing it to 3g, but the changes would not save that way. The only way I could get them to save was to power off the phone, take the sim card out and put it back in, and then reboot and switch them. Once i pick a new setting (which is now set on 3g), it locks it and I can't change it again without removing sim card.
When I look in About Phone > Status section, I'm seeing the network says searching for service. The mobile network type is unknown. The service state is out of service, and the mobile network state is disconnected.
Is there anything I can do to fix this issue? If so, I would truly appreciate any type of guidance you guys or gals could give me. Thanks!
I didn't read your entire post but myself and several others have reported signal issues after 4.4.4 flashes on all different ROM types. I think 4.4.4 is just picky about what firmware and baseband you're running. I flashed a few different RPM packages too but in the end I got lucky flashing the BLK3 modem and it seemed to fix my issues. I had noticeably poor signal strength most of the time and a couple times I would look down at my phone and I'd have no signal at all.
Maybe a dev or expert can shed some light on the root of the issue. I don't know enough about under the hood stuff to make an expert diagnosis.
Edit: The unanimous fix that everyone appears to agree on is to flash the MF1 AIO (all in one) package and then flash the ML1 modem only. Problem is finding a legit source for the MF1 aio package seems to be up in the air.
Like I said though, I didn't even do this. I was just trying all kinds of combinations of modems/aio's/ and rpm's and I got lucky. 2 days now with a solid signal at all times. LTE speeds are blazing too, 45 down and 10 up.
Check ur imei number. Or flash a backup and see if that fixes ur problem.

Can you share the specific steps you took? What worked for you and where can we download it from?
thanks!
Hi all please go easy on me as i'm not a Dev , but I do like to test your hard work out guys :good::good: much appreciated!!
Ok I bought the 64gb OPO in envy of the flagship killer!! i'm glad I did, but it did not come without its hickups :silly::silly:
From it's quite stable stock Kitkat cm11s rom to cm12 lollipop through to the new cm13 & cm13os.
I have been running it on the the uk network Three (3) .
Now the main problem I was facing with my beauty was signal dropping that required reboot to fix.....
As I live in North Wales where you have mountains & hills and mostly bad weather I would loose signal at least once a day but that required a reboot to fix!!
tried so many fixes but they made no difference to my network.
I have stumbled upon a fix that actually works.
no more checking APN or resetting access points. :good:
so here goes
Please download cm13 latest snapshot official rom or cm13os (google search)
make sure you have TWRP V2.8.6.0 recovery. (google search)
then download this RADIO Firmware and Flash in Recovery:- bacon_firmware_update_2016_1-25_.4.0.1.c7-00011.zip
(use google search)
I cannot provide links sorry I need 10 posts.
this Radio firmware worked!!
I have tested in bad signal areas with my 3g and LTE signal dropped, back into good signal areas!!!!
with no REBOOT required :victory: it instantly got its 3g or 4g back. tears down my eyes!! so happy this worked.
please note that I have only tested with 3 uk
this may work with other peoples issues with signal on different networks & Custom Roms. please comment to let us all know the result and what networks.
If someone can rewrite this thread with links , please feel free to do so, CREDIT GOES OUT TO ALL
i have cricket wireless in central texas, and at my house I get awful signal. to the point where itll take several minutes just to send a text. but if i pop my sim card in my cheapo 30 dollar phone, great signal. few days ago i flashed coloros and have noticeably better signal so far... not sure if it uses a different modem, but so far its working and loving the rom
