No Data on Sprint Suddenly

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.

unknowingly bought a rooted G Flex 2 LSS996

Hello everyone,
Around the black friday weekend, I have purchased a LG G Flex 2 LSS996 on a ebay store. It was unlocked and worked as advertised on 5.1.1.
I could never install any android or firmware updates, which didn't bother me until I also got the throttling/ overheating problem. That's when I noticed that the phone actually is rooted. I wish to upgrade my Android now, which is why I am thinking of unrooting the phone. I thought of ROMs as well, but I haven't found any and I don't have the time and knowledge for ROMs or Xposed Framework.
I'm not sure why or how this phone was rooted, but I fear it has something to do with the carrier unlock since it is a LSS996 for Sprint. Because I want to use this phone outside of the US, the phone would be unusable for me in case the phone gets the carrier lock again if I unroot. Would this be the case?
I'd be happy about any reply! Thanks!
EDIT: still looking through this forum.
Just found this: http://forum.xda-developers.com/g-flex2/help/managed-to-gsm-ls996-awaited-apn-t3090484
Meaning that the seller probably did the same thing right? Will unrooting lock the phone again? I'm not sure what exactly what unrooting does to the phone in regards to these files. I would unroot via SuperSU
Some other things worth mentioning:
- The "hands-free activation" (not sure what it's called in English, I use the phone in German), which starts on every phone start up, never finishes properly. I can let it run through its 5 cycles or press activate, either way it fails.
- When I press "activate this device" in the system settings, a black screen with "self service" on top opens and the immediately closes.
- When I want to update PRL, profile or firmware in system settings -> software updates, I always get an authentication error.
Other than that and the throttling/ overheating issue, the phone works just fine.

I also have the same device. The phone is rooted because someone modified system files to unlock it. You can flash an unrooted system image for your software version and update the phone, and you wont lose carrier unlock. The things you have mentioned are normal for such a device, since it is not unlocked by Sprint.

Thanks for the reply!
How do you suggest flashing? I'm not finished researching, but so far flash fire looks like the most convenient option.

Help Needed with Gflex Error Message

I purchased a Gflex from a friend of a friend and after 4weeks the ATT phone started to boot loop. (I have Tmobile) He had mentioned he unlocked the phone but after the boot loop the phone hard restarted and i lost my 4glte options and could only call out or call in.
There was no internet options nor could i send photos or text messages nor go online to use any apps. I took it to my Tmobile store and they couldnt figure out why the phone would not pick the 4g option.
After a bit of reading I purchased a new IME number and figured I could un lock it myself. But when I reboot to choose the service provider where i unlock the phone the LG GFlex flashes a message saying its permanently locked. Seems like the phone has reached its 10 of 10 limits of unlocking the service.
This is where Im at... Do i need to Flash the phone with a fresh reboot?
is there a different way to reset the 10 of 10 entry limits?
I need a little guidance here. 1st timer.

Assistance with (partial)Bootloop and Locked Bootloader.

Hey there forums.
I've been an active browser of XDA but never really created an account but I've done so to have assistance with a particular situation with my device.
So the other week, i had spent 150 dollars on a Sony Xperia XA F3115 from Vodafone, Australia and it turns out that the bootloader was locked because of Vodafone and i wasn't going to pay 50 dollars to unlock it. I alternated and browsed the internet (Mostly XDA but other sources aswell) to figure out if there were any methods of bypassing this, whether it be easy or not - I was willing to try anything that seemed like it had a chance to work, without a 100% failure rate. Reading responses to particular methods, i was drawn into one method of just reflashing the stock firmware onto the device and then rooting, flashing and doing everything from there (as the device was no longer locked by Vodafone at that point).
I have completed this task as of this morning, and the device booted successfully. As soon as i unlocked my device, i had received the general android setup window but half way through, i got spammed with "Name has stopped responding" countless times to the point where the phone was literally unusable, it would just pop up again right after closing it - So i decided to restart the device. This was probably a big mistake, it booted fine but it said "Android is updating" and had the whole "Applications updating 100 out of 255" stuff happening. Then it booted to the lock screen, which i had previously setup before i flashed the device which didn't really surprise me too much.
Then it rebooted. Now every single time i boot the device, it reboots to the "Optimizing apps blah out of blah" and then will reboot upon the notification bar popping up, but no lock screen. I decided that my best cause of action was to download another firmware and try that one instead, but I'm unable to boot my device into bootloader mode as it's impossible to happen. I turn off my device, plug it in and hold the volume down button but it refuses to work anymore.
Now that the situation has been explained, I'd really like your help to see if i can have this resolved. I'm baffled as to why Vodafone even locked it to begin with, since the phone was prepaid and had nothing to do with any sort of plans - nor was it even available as a plan. I don't have the money to buy a new phone, and they have already denied me a refund. I need this phone for work and the mistakes i made were stupid - Please, i need assistance. You're all hopefully more tech savvy than i am in the field of mobile phones.

Bought used 970F with Magisk, relocked, flashed stock UI5, no network at all

*****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
