Short and sweet. I am unable to activate data all of a sudden on Sprint. My other family member's phones work fine, but I cannot update the profile or the PRL. It just says "Network Error, try again later." Phone calls work fine, and my baseband and all that jazz are showing. It also shows 3G occasionally, but it still says network disconnected. Any ideas would be greatly appreciated. Thanks!
Update: I've reflashed EFS, and that seems to get me data on most ROMs, except Android L and stock 4.4.4. The second they try to do hands-free/update profile or prl, the update fails and I can't get data. Any ideas? Could it possibly be my SIM card? What's weird is that even when I have a data connection(like on the restored efs), I still can't update profile or PRL...
I've searched the internet for the past week, and nothing has worked. I haven't had a chance to call Sprint and complain, but this is starting to be quite frustrating. I've had data the whole time, but I still can't update profile/prl or complete the hands-free activation. So I can't even go back to stock, because when I do the factory image, the hands-free fails.
Eww sorry man. Probably APN.

What the.... So apparently sometime last night, my PRL updated on its own, like it's supposed to(old one was from old efs restore). But I still can't manually force the two to updates. So hands-free still fails upon a reset. This practically confirms that my phone is fine, because clearly it can receive the updates, just not pull them down. I'll call them today and #blamesprint.
APNs should be restored upon efs flash right? If not, how do I check them? The APN menu in settings doesn't appear when on the Sprint network.

You'll have to download an APN app off of the Play Store. When I had Sprint there was weird issues with the bearer field. Also they have like 4 different APNs stock and there was one like i.ispnt or something that seemed to work but you had to select between bearer EHRPD (LTE network routed EVDO) or LTE.
All APN apps are giving me an error saying SIM card unknown, even when installed to system. One even says Virgin Mobile. Could this be an issue with my SIM card?
Could be a problem with your SIM card. I'd just take it into a Sprint store quickly and get it resolved.
I fiddled with APNs, there were 12 there(!), so I reentered the correct 5 and could reliably get data. I factory reset and now my phone is unprogrammed(no MIN and wrong phone number), I'm just going to go yell at Sprint now. :fingers-crossed:
Sprint was useless, the tech kept blaming the phone, saying things like "Nexus phones don't have dialer codes" and "your IMEI is bad(WTF?)", then she noticed the padlock on the boot screen where she refused to go further, saying that I tampered with my device. After I informed her that it was MY device(purchased unlocked from Google) and that Sprint had no legal claim to that device, she redirected me to Advanced Phone Support. She also refused to give me a new UICC card, saying that "it couldn't be the problem." I'm done with Sprint for the week, so I'm just going to go custom again and just set the APNs properly each time. Even on stock/L, I can just flash the Sprint APN zip to automatically fix them, correct? If so, where could I find the latest APNs? The latest zip I have is from March or so I believe. Thanks!
Also out of curiousity, how hard do you think it would be to force my way out of a contract ETF-free? I figure if they can't prove it's my device that's faulty, and they aren't giving me a product that I'm paying for.......

thats easy force it to data roaming and start streaming the heck out of anything and everything overnight. Sprint will terminate your contract if your roaming data is consistently to high.
People,
I hesitate to ask the question again, but I promise you that I've read everything on the subject that I can find (including many of the 171 pages of the "Nexus 5 Flashable Modems and EFS Backup" thread...) and also on a lot of other sites.
My son's N5 on 5.1.1 ran out of battery a month ago (it worked perfectly for the 15 months that I had used it) and when he recharged it he'd lost mobile data. He had the mobile service triangle in the notification bar, but empty. No service.
I have tried absolutely every suggestion that I've read. Airplane mode on/off. Flashed 3 older radios. Installed older Lollipop & Kitkat 4.4.4 from Google Nexus factory image site. Installed the latest nightly of Cyanogenmod. Installed MPZ79M. Rooted it. Nothing works.
I don't believe it's a hardware problem - when I remove and replace the SIM the notification goes from the square with a diagonal bar across it ("no SIM") to the empty triangle. But as soon as I reboot (not just screen off & waken, but full restart) the triangle is replaced with the "No SIM" square again. The same reaction happens on the initialisation after a factory reset - at the "Register SIM" screen it says "No SIM", but extracting and replacing the SIM starts the "Attempting to connect to service" sceen, though this just does nothing until my patience runs out and I skip it. The SIM itself has 3 scratches along it, so all in all I don't think it's a contact problem, but something in the software. The SIM works fine in the Nexus 4 that I've given him.
EFS - I don't know enough about it still, but the phone displays the correct IMEI, so I'm hoping that this means that the EFS is not corrupted?
I know that this is a well-known problem, but on the off-chance that somebody has read a solution that I haven't found...
Thanks for your patience and any help you can offer.
Oh well...
...I guess I have a £350 paperweight?
I suppose at least I can use it as an entertainment console, since wifi seems to be ok. But a terrible shame to waste such a beautiful device.
Maybe you already tried it... Just to be sure:
a) You have incorrect APN configuration, to solve this try resetting your APNs via Settings > Wireless & networks > More > Mobile networks > Access Point Names and then click in three dots above and select "Reset to default".
b) Your mobile phone antenna unit is not working properly, solving this is pretty easy, shutdown your phone, remove your phone's back panel very carefully (using a plastic material..i did it using guitar pick) and then you'll see two wires adjacent to edges of your phone, just remove and refix them gently and reboot your device.
c) Reboot in safe mode and try to play with the preferred network type.
d) I had this problem "No service and no signal network in nexus 5" after restarting phone.
I tried to restart phone few times again and reinsert sim card. No luck.
Then I took sim card out while phone was on ( I forgot to turn it off) and reinsert it and now it's working fine.
It must be a contact problem. Just not shure how long will it work.

Thanks, Primokorn, I'll give your suggestions a go - appreciate the ideas.
I have tried the APN settings, but since there's no SIM (huh!) it's greyed out, though it's temporarily updateable if I extract/replace the SIM while the phone's on - but it's grey again on the next reboot.

Primokorn,
No luck. I tried all of these with no result at all. It looks as if this is a very serious flaw in the Nexus 5 - I had my doubts, to be honest, when my son said it started after the phone ran out of battery, but I see exactly the same explanation from other people in the huge number of threads reporting this no-radio problem. How can Google issue such a good phone with such a lousy bug in it...? No point in even asking them (though I've seen at least one person who tried with an impressivly helpful response from the Google support person) since not only is the phone out of warranty but it has been rooted.
Oh well, I enjoyed it while I had it...
Hi!
So I have a Galaxy S6 which came with a Dutch T-mobile package. On my way to China, where I moved a few weeks ago for an indefinite period, I cracked the screen and brought it to the local repairman to fix. That went perfectly well, but the phone didn't recognize my fingerprint anymore and I forgot my backup password. That's why I performed a factory reset, and that's where the real trouble began.
After the reset, I tried setting up the phone again, and got to the Samsung reactivation screen. I entered my account info, and provided the password for the wifi, after which the phone connected to wifi (with the corresponding message), but after a few seconds I get a pop up message saying "Unable to connect to the Internet" - even though the wifi symbol would still flash its arrows in the upper right corner. Thus, I can't get past this screen nor in my phone, which is quite a devastating fact as a poor new expat in China . Tried several other wifi networks, to no avail.
My guess is that it's the Great Firewall of China acting here, somehow preventing the phone to connect to the Samsung (and/or Google) network to check my info. I don't know if this is correct, the Samsung helpdesk couldn't say for sure as well, but I really really want to find a workaround here. Once I get the phone working again I can install a VPN to have the Google stuff working in China, but this way I can't get to that point. Now I am completely new to rooting/ installing ROMS and the works, but I am willing to try anything to get this expensive piece of electronics to work out here.
Any helping comment is an absolute lifesaver, and I will name my firstborn child after you!!
Thanks so much!
All the best, Maarten

Hello All,
So I have already smashed one of these phones against a wall; that is how frustrated I am right now. I got a couple of SG J3s (J337U), which are unlocked but unfortunately, cannot get them to work. The recognize my sim card and all, but as soon as they get data connectivity, knox enrollment service runs and mobile data gets deactivated, and calls are blocked ("Call not sent" error). I have not been able to find any way around this; it seems there is no way to root this device and there are not custom roms or twrp for this. I have tried to uninstall/disable all the apps that reference knox using adb, but so far, no luck. Someone mentioned there were able to use a magisk patched boot image to go around a similar issue, but when I created a patched image with magisk and try to flash using odin, I get a failure. I am hoping someone can help me figure this out before smash the others against something I bought these as presents for folks in my neighborhood and now I cannot return them as I had to toss the cases to make room while flying home. I appreciate any and all help I can get.
Thanks

carriers are getting sneakier about ways to get their phones locked and many have resorted to firmware that only allows calls over a specific set of conditions. TextNow wireless is one that comes to mind. They use the handset as an EMTA basically and the calls are all completed via VOIP to the switch. Thats hard enough to deal with let alone if they also implement use of a VPN to go with it. i say this assuming that youre trying to use the phone on a network it wasnt sold at the store originally for, correct?
I'm having the same issue with this a10e running and.10. i can't activate mobile data it says security policy won't allow mobile data connection. I have beat my head against the wall trying all these fixes for hours now. I could really use some help please.
I have a Galaxy SM-J337U (J3 2018) and its doing the same. Sees SIM and carrier, but will not make a call, receive a call, send or receive a text. Wondering if someone solved this
*****FINAL UPDATE: THIS POST IS A WASTE OF TIME WANDERING AROUND SOLUTIONS FOR THE IMEI. THE REAL REASON IS THAT I WAS SCAMMED AND BOUGHT A STOLEN PHONE WITHOUT KNOWING, AND THE IMEI/IMEIs WERE CHANGED, so when I factory reset the phone, the IMEIs were gone. If you're in the same situation, see if you can return the phone. If not, the only thing you can do is sell it AS IT IS, because YOU WERE PROBABLY SCAMMED, LIKE ME, so please sell it declaring the state of the phone and the IMEIs.*******
****If you want to read the entire post, go ahead, but you'll waste all your time. You were scammed, it's a stolen phone, end of story.****
Guys I was really excited about this purchase, I tested network with the seller, on both SIMs, both worked great, 4G data, when I took it home I noticed the phone was BL unlocked with Magisk, which made me worry about any security issues or not being able to update. Relocked BL from download mode, flashed stock G970FXXSDFUI5 (I live and bought it here in Colombia), and I checked this was the same FW that it had while rooted with Magisk
Cleared data/cache, flashed successfully, warnings gone, but no network at all, this is what I have:
- Only emergency calls with any SIM in any slot, already tried different carriers
- Checked IMEI in national blacklist database imeicolombia.com, they're both clean
- When trying to make a call "not registered on network"
- When going into Mobile Networks - Select Network - Select Automatically is ON, if I try to turn off it instantly says "Error searching for networks" and the switch stays on, so no "Manual Search" button.
Already tried clearing data/cache of SIM Toolkit app, what am I missing? Thank you!
UPDATE: I went through all the process of unlocking BL again and rooting again with Magisk successfully following this tut
with updated Magisk, etc, but still no ntwk, will now try flashing other countries same/higher SW REV, will post any other update.
Additional steps: I tried putting 2G only or 3G only and reset APNs to see if "Select Automatically" switch was fixed but same story, it wont turn off and shows same "Error while searching for networks" msg right away
UPDATE 2: I wanted to share a video I found that shows the exact same error that I get in the "Mobile Networks" menu:
Altough I rly dont think it's the same situation, cause in that video, the phone has no signal at all, mine is able to pick full signal for emergency calls. I rly dont think my situation is that of hardware but some kind of software/activation/sim thing (It's not the SIM bc it works in any other phone)
Please someone help me, I've invested more than labor hours researching and trying to fix this, I fear I could damage the phone by flashing it so many times

A VERY VERY VERY complex process. It turns out the answer was a very simple one. They sold me a stolen phone with the IMEIs changed, so at the moment that I factory reset the phone, the "fake" IMEIs were cleared, leaving the phone with NULL IMEIs. In short, I got scammed, had to sell the phone declaring the situation, ofc for a quite discounted price due to the fact of it being a stolen phone.
ALERT 1: WHEN YOU'RE GONNA BUY A SAMSUNG PHONE, ASK THE SELLER IF IT CAN BE FACTORY RESET RIGHT IN FRONT OF HIM/HER BEFORE PAYING. IF THE SELLER SAYS YOU CAN'T, YOU CAN ALREADY GUESS WHAT'S GOING ON.
ALERT 2: NOW THEY CAN CRACK THE SAMSUNG PHONE IMEIS SO IF YOU FACTORY RESET, IT WOULD KEEP THE FAKE IMEIs, so the only thing you can do is go into this website:
IMEIpro - free Samsung IMEI checker
Check information about your Samsung cell phone - model, serial number, manufacture date. Verify Samsung carrier, age of the phone, purchase country, CSN number and other details.
imeipro.info
Enter the IMEI and the website will show you THE SERIAL NUMBER. COMPARE IT WITH THE ONE SHOWN IN THE PHONE. IF THEY DON'T MATCH, THE PHONE IMEI HAS BEEN CHANGED, LIKELY A STOLEN PHONE! DO NOT BUY IT!
This is the best guide I have for buying used samsung phones so far
