[LG G6 Questions and Answers] TrumpetWinsockError:
Hello readers and devs,

TL;DR

Debranded a Sprint LG G6 --> Factory & Hard Reset phone --> SIM card not being read.

-----

Need help getting my phone back on MetroPCS network after a debrand. I will try to be a thorough as I can for SEO robots and to explain as best I can what I did and what I noticed changing.

!!! action --> I debranded (unbranded, sic) my Sprint LG G6 993 phone using the code provided in the forums, hoping for the best.

I noticed the following changed after debranding:

APNs were locked (not able to create new or edit, however the MetroPCS APN was still there)

Sprint logo during boot gone

WiFi Calling option gone (was not working on MetroPCS network anyway)

mobile settings -> network mode -> GSM and Automatic options missing; set to LTE/CDMA

the cellular network connection to MetroPCS was not functioning properly

SIM card error when a phone call was made, no texting either

So, I naturally read through the forums to try to get the phone working properly again on my network. I read the topic Sprint LG G6 (LS993) Dial Codes.

!!! action --> I used the code ##72786# to "Reset provisioning and makes phone reactivate".

After that, I noticed that the MetroPCS APN was removed. APNs still not editable. At this point after reading some more on the forum I decided that I needed to get the phones MSL code, go into the service menu and edit the APNs from there. However, after getting the MSL and going into the service menu area, the APN area would still not allow me to edit the fields.

I went to MetroPCS to see if they could put a new sim card in the phone, hell for all I knew maybe my sim card was bad, remember when I try to make a call I get a SIM card error message. MetroPCS guy tries some things, calls up a service person on the phone, says nothing is wrong with the sim. Tells me to come back in 30 min. I go over to Sprint, give them the phone and tell them what is happening. They say the phone IS unlocked. Then a sales rep tells me that debranding the phone means that it is no longer a Sprint phone and they will not touch the phone. I ask nicely for a tech supervisor. Sprint supervisor says that I should try to Factory Reset the phone. I go home, backup the phone and do a factory reset.

!!! action --> Factory Reset the phone.

Changes:

mobile settings -> network mode -> GSM and Automatic options appear again; set to Automatic

Still unable to add or edit APNs (the APN area options are all greyed out).

!!! action --> I take out the SIM card and put it into my previous phone (Samsung Galaxy On5) thinking well i need a working phone.

I get an error, On5 is not connecting to the network, needs to be activated.

!!! action --> I take out the sim card and put it back into the LG G6.

Changes:

Invalid SIM card error (phone does not detect the sim card)

The SIM card is not being detected by the phone.

I read the forums some more and discovered a post that referenced a LG G6 that was debranded and to get it working again the owner had to buy a Sprint Prepaid activation SIM to re-provision the phone to get it working again on his alternative network.

I downloaded a SIM Card reader and the LG G6 doesnt give me any information on the sim card. If I put the SIM card into my On5 phone and use the SIM Card reader app I can see that my SIM card is okay and all data is displayed properly for the SIM.

I am not really sure what to do, but try to get a Sprint SIM card and put it in to try to reprovision the phone to Sprint and then move it back over to MetroPCS.

Please help what should I do now to get the phone back on MetroPCS?

Thanks,

Trumpet
