Hi. I have a Sprint LG G5 that I gsm unlocked using the hidden menu apk. I received an Android update last night of 470mb. Since I updated the phone is showing Invalid Sim. How to get it unlocked again? The hidden menu apk now shows completely different menu options. I cannot access the previous menu anymore. Please help.
Maybe your device got sim locked again?

I have same problem. Help us someone please . Thanks
The new zvc update blocks the hidden menu. Look in the sprint threads. Do not attempt downgrade or brick will occour. And there is apparantly no zvc tot or kdz yet so no fix. The only option is a 3rd party remote unlock service. That can also unlock the apn menu so you can have data also. If not you will get calls but no data or mms.
The resason for no downgrade is sprint and lg increased the antirollback increment higher so no zvb-zv8 any more.
But as history goes with sprint lgs. Everytime the anti rollbqck goes higher a firmware ussually gets released. Same seems true as for the sprint g4.
This happened to me as well, any luck finding a solution? We already have talked to Sprint, but they say the phone still is unlocked in their end, however the phone still says invalid sim.
Maybe try "Unlock UICC" under the system updates menu? I'm on factory rom with no hidden menu stuff. But had to do "Unlock UICC" even after Sprint said they had unlocked the phone for me.
When ever sprint unlocks and post lg g2 you have to also click uicc. They aprove it but its like a profile update

I've tried T-mobile's APN and called metro for theirs still no luck.... all it says is no service and that "Sim card is not verizon." Not sure what im doing wrong. Set to global and LTE/GSM tried APN in both setting with reboot. Nothing....
It's stock 5.0.1 no root. Everyone says they have theirs working but the thing is i cant even get the service to start. Where am i going wrong here? Thank you in advance for any help.
Did you call MetroPCS and provide your IMEI?

No i didnt. I'm guessing thats required?
If thats the case i'll feel really dumb. I'm new to unlocking, not my strong point.
MetroPCS requires it... not sure about other carriers.

you need to sim unlock your device I'm not sure that needed to be said but its kind of obvious... after sim unlocking you can easily enter in the metropcs-fast.metropcs.com or tmobile apn settings with any of my ROMs and get a signal. I know because thats my setup as well. i know their supposed to be factory unlocked or whatever but for me to rid myself of that sim error I had to call VZW and get the actual unlock code for the device and enter it in the old fashioned way. they are supposed to or will guide you if you call in and the phone is paid in full. then yes register the imei number and your metro sim card number with metro which takes maybe 5 min and you're set.
Hi,
I have just return from US and I got a LG Leon from MetroPCS to sty connected while there. Now that I am back I unlocked the phone via unlock app. My surprise came when I put me Spanish SIM card (Jazztel) and the phone only gets 2g connection. I have been searching the net and I found some threads on the topic but I can not make any of them work on my phone. First I tried changing the radio to Europe mode through *#*#4636#*#*, and I enter the test page but when I click the phone info button I get a message that states that I can not run that application on this device. I thought it was because I wasn't root so I rooted it. But before I could root I had to downgrade by flashing an older firmware. No way, I get the same message. I tried the hidden menu to see if I could find an entry to change the radio mode, or any type of LTE configuration. Hidden menu on my phone though 277634#*#. I also tried the anycut option, but I do not get any facility called LTE configuration or similar.
I am desperate and I do not know how to proceed. Any help is welcome
Thanks in advance
Hello there fellows, i'll try to make my question simple. My uncle got a new phone so he threw away his old one which i took, its an LG V10 H901 its T-Mobile if i'm not mistaken, Anyways I'm out of Canada for a long time now and the phone is fully unlocked and runs on all the networks i was able to test, but its running android lollipop and i really upgrade to nougat, but from a previous experience with a Galaxy S6, upgrading just like that might lock back the network, and i have no idea if its the same case for this V10 too, as i am not in Canada anymore even contacting T-Mobile won't be that easy at all (tried before), so what i wanna know is, will the network get locked if i upgrade the Android ? as i'm going to do it manually since i can't receive OTA outside the region.
All informations are appreciated, and thanks in advance.
Edit: In T-mobile website where i enter the IMEI to see if my device is illegible for unlocking i got a congratulations saying my device can be unlocked.
- Also, The phone is rooted so my guess the bootloader should be unlocked right ? (Stock recovery btw). Now the weird part about that is that when i try to reboot to fastboot/bootloader from Terminal/ ADB/ Volume Down And USB/ Application With Root, there is no fastboot or bootloader i guess, i even found a similar post on the forums here but no answer for it too!
Now my guess that flashing the KDZ will flash all partitions and fix it but i am still afraid of the carrier lock!
In general, once a phone is unlocked, it stays unlocked forever as long as it disables the sim lock check in the phone and updating the software or doing factory reset doesn't change that. From what I have read and researched previously, the sim unlock status is stored and enforced via a certain partition on phone for example, in some phones it is nvram or nv data partition, the same partition that stores phone's IMEI number as well. It is not likely that you will loose sim unlock status just by updating to nougat.
But do keep in mind that that some of the LG V10 H901 T-Mobile versions have a korean motherboard where LG Bridge tries to update it with the wrong version of the rom bricking the phone, and people have reported here on XDA that even after unbricking they lost their IMEI info from the phone permanently and phone modem stops working.
I would suggest that you make sure which sub-variant of the H901 you have before you attempt to do any flashing, especially through LG UP.
I personally just bought a used H901 myself and was trying to decide if my phone is one of the ones with korean motherboard.
Hi, i have been trying to find an answer to this after hours of searching i've come up short and confused.
I recently switched from tmobile to verizon, and i paid off my tmobile s9+ and had it sim unlocked. When i put my verizon sim in it, nothing really happens. either it tells me that it can't register on the network or to insert a tmobile sim card.
I have tried using reset and factory reset. I have also tried the method of holding the volume bixby and power and doing a factory reset, then putting the sim in, rebooting, etc. That doesn't work either.
I see several people trying to go from verizon to tmobile, but i haven't been able to find anyone going from tmobile to verizon, and what method i need to do to get this to work, if its possible at all. Any help would be so much appreciated!

Use Odin to flash U1 and then go back to U. Just leave the SIM in. Don't use HOME CSC.

That still may not help, remember Verizon is still CDMA and the T Mobile branded phone does not have CDMA bands activated and they may not even be on the phone, I don't know. Granted band 13 should work fine, being LTE, but could the sim be looking for a CDMA radio and that is why it is not working?

The hardware is identical for all US Galaxy S9 phones. Any bands that may be missing will be resolved by flashing firmware. OP could also just stay with U1 if they want unlocked, and all bands would still be there.

As per Samsung chat support, I've asked if the dual sim version (international) will work with Verizon. I've also asked the rep if I can switch carriers with a locked phone. They said that essentially, all phones were manufactured with the CDMA and GSM band compatibility, it just needs to be unlocked and the US versions will work on any carrier in the US and the international version (dual sim) needs to be unlocked and it will work with any carrier in any country.
That said, it seems that you're just having an unlocking issue - which is good and bad. I hope you figure this out. Try using Odin 3.13, get the CORRECT firmware for U1 or U(VZW) to flash your phone

Only one small correction to what they told you: The 965F (international), will not have CDMA capabilities. That might not be a problem on some US carriers. But if you can't get VoLTE working on VZW with 965F, then you're dead in the water, since you don't have 1x CDMA calling to fall back on. It becomes a data-only device. I don't have experience with it, but I wouldn't be surprised if the VoLTE doesn't work on US carriers. For GDM/WCDMA carriers, you'd probably be just fine with 965F. Even if VoLTE doesn't work, you'd still be able to call.
Hope this helps.

Step 1
Can you find out the exact model number?
For T-Mobile, it will be one of these :
SM-G965UZKATMB (Midnight Black)
SM-G965UZBATMB (Coral Blue)
SM-G965UZPATMB (Lilac Purple)
The U is the important part, as a previous poster explained that the F models do not have CDMA support (forget what that actually means, just know its necessary for verizon)
Step 2
Next, make sure that the carrier version is correct.
Example: SM-G965UZKATMB
BST Boost
VZW Verizon
ATT ATT
USC US Cellular
ACG C Spire
TMK MetroPCS
VMU Virgin Mobile
TFN Tracfone
XAS Sprint
TMB T-Mobile
XAA Unlocked US
SPR Sprint
CCT Xfinity Mobile
Essentially, you need the firmware that starts with SM-G965U and ends with VZW
Step 3
I'm not 100% sure on how to flash from carrier to carrier but there will be a list of directions. You may need to do some research there to see if it will void samsung warranty (aka 'trip knox') or anything like that, if that matters to you. I think only a modified version of Odin will be able to do this.
Download Odin v3.13.1
Extract the firmware file you just downloaded. You should get 5 files:
AP (System & Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_OXM (OXM CSC file, will wipe your phone)
HOME_CSC_OXM (OXM CSC file, will NOT wipe your phone)
Add each file to it's respective field in Odin v3.13.1. Use CSC_OXM if you want to do a clean flash and HOME_CSC OXM if you want to keep your apps and data.
Reboot your phone in Download / Odin mode with the following button combo: POWER + VOLUME DOWN + BIXBY
Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a blue box will show up with the COM port number.
Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.
Click the start button, wait for Odin to say 'PASS'. Once the flash is complete, your phone will reboot.

Step 4
To download firmwares, google "SAMMOBILE website: /firmwares/galaxy-s9-plus/SM-G965U"
Looks like the latest verizon firmware is here: SAMMOBILE website /firmwares/galaxy-s9-plus/SM-G965U/VZW/download/G965USQS2ARF4/223287

Hey thanks a bunch, I’ll give this a shot when I get home tonight. It very well may be that the rom I got wasn’t the right one. Other threads I’ve read seemed to indicate that everything was universal now and by having the SIM card in the phone while flashing, it would download the carrier specific stuff automatically. That part at least doesn’t appear to be the case since the phone wouldn’t accept it. But I’ll download some of the carrier specifics and see what happens. Thanks again!
Did you get it to work after all?
Sorry that i forgot to update! I did get it working, but it required a bit more discussion and help on a reddit discussion someone started. I noticed that someone asked this exact question and i pointed him to this thread where he was able to get it working, then helped me with which roms he used, and i got it working as well! I've been using it daily for almost a month now. Thanks so much for everyones help, i hope that if anyone else is trying to do this, between the two threads it can help. Heres the link to the reddit thread https://old.reddit.com/r/verizon/comments/909iag/tmobile_s9_on_verizon/

Awesome gigatigga - thanks for getting back. I'm on the verge of trying this. I owe some money on my S9 plus on t-mobile but before i paid it off wanted to make sure all is good.
How are the speeds? Everything working ok? Thanks again! :good::good:
Edit: I was all set to do this and during the signup - I found out that my imei wouldn't work in Verizon's system so they used one from another phone. He advised that if I wanted to pay for insurance, if I make a claim it could be an issue because the imei numbers won't match up. Seemed like a big red flag to me. So I didn't go through with it. Wonder how others are handling this?
I just switched from the ATT firmware to ARF4 on T-Mobile, but it says there is no update available, while the newest T-Mobile update is ARF7. Does anyone know how to get updates OTA?

Can someone help me?
I cannot network unlock a T-mobile Samsung Galaxy 9 plus which has never been active on any plan. When I insert my Verizon SIM card a system notification says "Invalid SIM card. Network Locked SIM card inserted".
I want to bring this phone to Verizon where I have an active plan. I don't have a plan with Tmobile and my friend gifted me this phone. I flashed it to Samsung stock firmware and bought an unlock code from DoctorSim. The code applied successfully however the phone doesn't unlock completely and continues to prompt for the unlock code when I insert the Verizon Sim card. When I called Tmobile they said only a phone active for 40 days on their network can be unlocked using the phone app and that my friend would have to call them to unlock the phone.

Actually, it is not a difficult process to extract that file.
First thing needed is to install QPST and enable the phone serial port.
After that, you need to open a program called EFS Explorer and then extract the files.
You can find a video that explains the process here

After installing the Qualcomm drivers, you will see LG Diagnostic Port, and LG Serial Port in device manager. Manually update/replace the serial port driver with Qualcomm HS-USB Diagnostics 9025. Then in the phone hidden menu you have to turn off the diag port under SVC, Port Check Test as shown in the video above. Then it should show up in QPST and EFS explorer

I have all the carrier_policy.xml files, TM VM EA. But I have some questions first. In which country and what is the name of the Carrier? The only reason I'm asking is: As far as I know, nobody in the US has crossflashed (most have been crossflashing the lmv600am) and really been able to get a 5G signal. Yes, I know it may have the 5G moniker on the taskbar but using Netmonster tells a different story, as do other tools. It's 4g masquerading as 5g. For example, on the v50/v60 on tmob network, using b66 shows it's 5g when it really isn't. When you crossflash with a KDZ the efs partition is not overwritten nor should it be because it contains imei info. Any file (carrier_policy.xml as an example) in the efs to be change has to be DL from the efs partition using Qspt, edit, and then reloaded. Show are you really getting a 5g band on your phone??????

I've been trying forever to get this to work with my ATT with stock FW and when crossflashed to EA, and you're right, I think it just doesn't, regardless of fw version installed. I've pulled the EA EFS policy files as well as the ATT ones, modified them, reuploaded and 5G just will not turn on. I've persisted so long because this method worked fine on my V50, however that one is a V500N (korean variant) whereas this is a V600AM (US/ATT variant), so I think that may have something to do with it. Have tried adding MCC-MNC, editing the rf_band lists, all sorts of combinations. I have a feeling that when the sim is inserted the phone doesn't even look at the modified xml files in the EFS partition and just generates it's own with the american models, but this is just speculation.
The other thing I noticed is that when I edit my ftm file to regain my serial number and remove the NT code error, the outer screen on the dual screen attachment works again, but then I lose 4G altogether and revert to 3G without data.
On my V50 all I had to do was add '5G' to some band lists and it worked, however, that unit is not crossflashed and still has stock korean firmware.

Well I can tell you that there's a running discussion on a lot of the points you just made not the least of which is whether or not the modem is being provisioned at activation and if so what exactly and how much.
I have 2 lmv600am which I got off Ebay. Both had been crossed to EA fw when I got them. Since I'm on Google Fi, I went to the AT&T unlocking site and Sim unlocked. I then put my G-Fi sim into 1 of my v60 and sure enough I get a 5G moniker on my taskbar. Now during this time period Tmob is changing their policies on LG phones, mainly since LG is no longer in business. For example, lmv450 no longer actives on Tmob nor any of it's mvno's and I believe the same is happening for all Sprint phones plus all LG non-tmob phones. They're checking by imei.
So it didn't take long and bam, I wasn't even getting a 5g moniker. I call G-Fi and asked, WTF. I was told that G-Fi is now only allowing Google and Samsung phones to activate with 5G services, only 4g for V600am. Once again imei strikes. BTW you can page thru modem protocols here; *#546368#*600#>field test>modem settings>engineering mode to see if you even have the 5g protocol loaded. I use to but now I only have 2g, 3g, hspa and lte.
The only reason I'm bringing all this up is because Carrier Policies are changing with LG phones so It's worth a tech support call/chat with your carrier to see what's what on their side.
The next step would be to use a serious network app to verify what really going on. I think in your area the G-Mon app is being used a lot. I use Netmonster in the US. I saw a screen shot from a guy in Poland, I believe, that thought he was getting 5g only to find out that it was really lte+ 3xCA. He was getting 727.3 Mbps on the DL which is absolutely screaming. That’s faster than 99.9 % of the phones in the US.

Forgot to mention that I noticed that after a fresh flash, the xml files present in the EFS are different before and after inserting my sim.
Interesting but also disappointing to hear about the IMEI checking :/
I've been through hidden menu settings, and depending on which firmware I have installed I can see different bands and modem protocols available/activated, but can still never turn 5G on with my american V60's.
I had so much hope for this handset since firehose was made available!
Which reminds me, I even bootloader unlocked and rooted my crossflashed at&t unit. Successfully install Magisk etc, but couldn't enable r/w on system partition, even after generating and flashing a modified super partition. Something else going on here.
YOU need to check out the v60 group over on Discord.

Increase the partition expansion to 300 or 400

How do you change partition sizes?
