Well I do this thread to see if anyone can help me, after updating to Oreo my device I ran out of mobile network. I have tried flashing almost all baseband variants without any solution. My device is unlocked and currently my network provider is Claro since I am from LATAM, if someone has a solution, I would greatly appreciate it. THANKS

Hello guys I was trying to root my Lg G pro E980 for AT&T. In my haste and eagerness to attain root on my device, I failed to notice some of the warnings in the OP. This is what I used to try to obtain root: http://forum.xda-developers.com/showthread.php?t=2362657 As you can see, it states that it does not work on AT&T 10p. After trying (and failing). My phone would no longer detect my sim card! I tried factory resetting with no luck. I also tried taking the sim card out and restarting without the sim and then reboot with the sim. This did not work either. Searching for networks yielded a network error. If it matters, my phone is unlocked and using a T mobile sim. I was working perfectly before the failed root attempt and now I get no service connectivity at all! Any assistance would be greatly appreciated!
Update: I flashed the phone to an earlier stock version of the AT&T rom using this: http://forum.xda-developers.com/showthread.php?t=2302660 and it still does not seem to read my T-mobile sim or an AT&T sim either! Please, any help at all is appreciated!

Have you still got an IMEI number? If you haven't that is why your phone cannot read the sim. If you don't have an IMEI, it is because your EFS has been corrupted but that shouldn't happen when rooting. If you have an EFS backup flash that, otherwise you have to take it to a service centre as there is no way to write an IMEI number onto your phone.
hi to all.

on xda we have unlocked many other harder phones and not a S4 mini!!!

The Sprint variant is a CDMA phone. I don't think it will work on GSM networks, if that's what you're trying to.

im looking to sim unlock the S4 mini L520 (sprint).
after i follow one of the unlocking guide i can access gsm,umts network setting, apn setting and many other settings.
so i think it just need a software like S4 L720 to unlock it.
i try the same software but shows DONE AND REBOOTS THE PHONE BUT THE PHONE SHOWS INVALID SIM.
BECAUSE THE SOFTWARE WORK WITH FIRST MODEMS NOT WITH THE LAST NE3 OF THE L520 BUT IM NOT FINDING ANY MODEM.
I'd be surprised if it's possible to get a GSM SIM to be recognized in a CDMA phone.
There are firmwares with old modem on sammobile, but unfortunately since the phone is already running kitkat, downgrading is impossible afaik.

but there is just the mk2,the phone was released on may 2013, so there is an older modem a think,

Do you have any news about downgrading?
Hello guys.
After a couple of days reading on the internet without success I decided to share my problem here.
I bought a LG g3 D850 32 gb on eBay, once I received it I was so happy enjoying the 4g LTE network, the speed was amazing.
Regrettably, one day all this happiness disappeared, now I only have Edge connection, I don't have 3g, hsdpa or 4g, I only get the awful Edge.
I have tried using my sim card on other phone and I get 3g and hsdpa (that phone does not have 4g) so the problem is on the G3.
I have to say that I have the phone with the stock rom and the only change I've done was to root it with kingroot and deleted (disable) some at&t apps. I thought this was the problem so I restored to factory defaults but the problem did not disappear.
I was thinking in to return the phone but I am in Chile so is a little hard.
I will be grateful if some one could help me with this issue.
I will be waiting for your comments
Thanks on advance

What model number/version/baseband/etc.
What's your base network and are you sure your APN settings are correct?

Hi Nick,
This is the Software info:
Android Version: 5.0.1
Baseband Version: MPSS.DI.2.0.1.c1.13-00058-M8974AAAAANPZM-1
Kernel Version: 3.4.0
Build Number: LRX21Y
Software Version: D85021r
Security Software Version: MDF v1.1 Release 3
I do not understand what the base network is. Is my cellullar provider?
The APN settings are OK. I didn't change anything.
I had all the connections and suddenly I lost 3 and 4 g and only get Edge.
I didn't change anything. I rooted the phone with KingRoot but I am not sure if the problem started in that moment.
I have made the Factory Data Reset a couple of times and the problem continues.
My Sim Card works fine in other cell phone.
Please Help!!!!

I had the same problem when I switched the operator. Went there and the man there tried everything but nothing helped. Last thing he suggested was to do a software update, did it an 4G speed came back

Yes, your cellular provider. What's your cellular provider and what's your APN? Is your sim from AT&T, a foreign provider or from a Chilean network? Does the APN match the SIM provider's APN?
I'm thinking that it's either an APN problem or a band switching problem (since you disabled some AT&T apps) or you just ran through your allotment of 4G data under your contract.
If you've tried your SIM very recently in a friend's phone and it works just fine, then it's probably not a data allotment problem.

I am using a chilean provider with the correct APN, the same I used from the first day when 4g were working fine and the same.
Yesterday I tried mi sim card in other cellphone and I got 4g without problem. I checked the apn and they was the same.
Now I tried with tho different ROMs, I changed the kernel and the modem and I'm still get only EDGE :crying::crying:
I do not know what to do. I think the cellphone is bad
I'm guessing that you may have disabled something when you were deleting the AT&T bloatware. You've got a D850, right?
As @trickie69r has mentioned in a previous thread, try downloading your KDZ direcly from LG's Servers using: http://csmg.lgmobile.com:9002/csmg/b...XXXXXXXXXXXXXX
(Replace XXXXXXXXXXXXXXXXX with your own IMEI, which can be found by dialing *#06* in Dialer)
Take a screenshot of your About Phone > Software Info tab before and after and see if anything changes.
Buena suerte!

Thank you Nick.
I have flashed some Roms, and the problem did not solve.
I have tried to download the stock rom but I can't download it from the link you send me. I can't find D850 stock rom.
Do you have other link to get it?

Did you try using the ROM in this thread, or just installing the AT&T apps to see if those worked?

Yes I tried that rom and stock kit kat and nothing works.
I think the cell phone is defective because I have other LG g3 and works fine
I've bought a european market ZE551ML and have it on the metro PCS network. Every APN I've tried both T-mobile and Metro fail to give me LTE or 4g. I had a previous ZE551ML that was on the same network that had no problem getting LTE. WW firmware phone with 4.21.40.352 MM Installed. The phones rooted and bootloader unlocked. I can get hspa+ but LTE is the problem . Attached are the Screenshots from my APN and phone settings as well as random network Data. Im a network engineer with alot of experience and I've tried everything I can without success a little help would be much appreciated and would using a custom ROM help in any way.
Unfortunately after adding over 7 tinypic URL images I had to delete them cause This is my first post which im sure would have helped alot.
Anyways thanks ahead of time.

Any luck with this? I am thinking about buying a Sprint A50 (SM-A505U) and flashing it with the T-mobile firmware (SM-A505U1) TMB. Wanted to see what your experience was before I made the purchase. I need the phone to work on T-mobile.
