Verizon Lg Vista VS880 flash CDMA to GSM possible? - Upgrading, Modifying and Unlocking

All the firmware rom's come with CDMA mode activated and once flashed it's impossible to switch to GSM mode, only if you are under the Verizon coverage with a verizon sim card. The apk patch that reveal secret menu founded on other pages don't work a app crash appear.
Im wonder if exista a firmware that came with GSM mode as primary network mode. Second in Lg Flash Tool i dont see GSM in "Select Type" only CDMA and CDMA Smarthpone(WM).
Wwhat is the best way to get the GSM mode for LG VS880 rooted without using apk.?

I don't have this device but, with a limited amount of threads for the LG G Vista, your best bet is to post this question within the following one that seems to be the closest one for some member guidance.

Flash LS980 to Page Plus

have a rooted ls980 on CloudyG3, TWRP. I used basic flash tool to get sms and voice working on Page Plus
I cannot get 3g working. I do have CDMA workshop . any tutorial on using CDMA workshop to flash LS980 to page plus with working 3g ?

have you change from Sprint to Undetermined ?
I just flashed and followed CloudyG3 FAQ which shows how to get data working. I use mine on TMO. Look at the FAQ post for Cloudy and you will be fine.
Mind you LS980 only supports UMTS2100, so you may not get 3G unless your carrier supports that band. On TMO I only get 2G at 200-400 Kbps which is still pretty fast.

TMO is GSM not CDMA bro...With GSM, most of your programming is in the SIM and through APN setting..it's different with CDMA...we have to flash our carrier settings (not the same flashing as flashing a ROM)

Sorry I thought your carrier was GSM.
I am aware CDMA is different, I was assuming you wanted to use it on GSM. If you want CDMA then yes you have to flash carrier settings.
I know some carriers flash Sprint/Verizon phones for their CDMA network so you could try that.

[Q] Unlocked Bootloader Possibility

As the N910P bootloader is not locked, is it possible to flash international LTE Qualcomm stock firmware, i.e. N910F, successfully?
Has anyone tried?
EDIT
Well I tried.
Stock N910F ...BOB4 did not flash via odin.
Echoerom 5.0.X flashed successfully. Flashing Modem + Bootloader of ...BOB4 via Odin after ROM fails.
Modem is the culprit to my pain. Is there anyway to trick the phone into thinking a different MODEM+BL is of Sprint origin?
REASON: I am wanting to use N910P internationally. It does not work as originally hoped via sim-unlock.
Unlocked International N910P
Great News for N910P owners. Unlocked bootloader = custom kernel = profit
Different band frequencies can be used internationally following the instructions in the OPs by .fffft[/MENTION] Mucho thanks to him.
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
FYI Steps:
1. Carrier Sim Unock / SSU apk
2. Select GSM/UMTS & go into service mode via ##0011# . Wait for GSM service. Menu Back Key. Menu Input "Q". Menu input "0000". Wait 5 seconds.. Find Menu item to change Network Preference to "Global". Leave it on this, do not change back to LTE or CDMA.
3. Input your APNs.
4. Root.
5. Appstore for SPCUtility or MSLReader. or ask Sprint for it if you are in good standing, tell you are going abroad.
6. Diag mode via ##DIAG#. Input MSL. Select CDMA Modem then Qualcomm. Select last option. CP + DM + Modem
7. Edit the NV items following the instructions of the above thread. Read, edit, write. I used QXDM program on Windows. If you are editing via CDMA Workshop or Tool I think you will need to select PDA in ##DIAG# also you will need both your MSL and 16 digit PW– 2012112120131219.
8. New Band Frequencies will only work on Custom KERNEL & ROM. DL and Flash for trltespr . Profit .
Flashed CM12 nightly w GAPPS
Praise the lord LTE bands work here in Canada.
They may work domestic if they are different frequencies/bands than CDMA networks. worth trying, but Im not in the US for awhile.
Cant wait for custom TW 5.0 ROMS to roll out with the hard work of the awesome developers here who keep me buying android!
Notes:
I don't have access to Service Mode anymore via dialer so I don't know how to go back to choosing preferred networks, i.e. Global, in CM. It reads "Global" on Settings>Mobile Networks . I fear switching to "LTE only"for having to do the whole process again via flash stock to access all the required menu again.
Edit : Lost LTE , only HSPA+ available

Convert A US Cellular Note 4 to Verizon Dev Edition?

... OK, I'm sorry for the clickbait title, but I think it could work.
I have a US Cellular Note 4 in-hand, and with CF AutoRoot and Flashify, it's permanently-rooted and TWRP is flashed as a custom recovery.
The device is carrier unlocked "for use on any CDMA network" and by default... it supports all the same bands as Verizon, with the exception of LTE band 13, which isn't an issue for me. (There is a method of enabling it, but that's a topic for another thread)
So, essentially, it's a Note 4 running on Verizon bands, and the bootloader is unlocked. Other than the USC software running on the phone, it's pretty much a Verizon Dev Edition in USC clothing.
Now... Verizon is currently working on acquiring the MEID from US Cellular, so I still have yet to actually get the phone activated... but everyone is optimistic. Even Verizon, and they're never cool with anything like this.
So my question: This USC Note 4 does not currently recognize a Verizon SIM. It came with a USC SIM which it recognizes fine, but I get "Invalid SIM" in my ongoing notifications, and "unknown" under About Phone > Status > ICCID. Verizon has told me that when the MEID transfer is complete, the phone will magically recognize a Verizon SIM. Is there truth to that? My thought is that I might need to flash Verizon software on the phone to get the SIM to recognize. Sooo...
Is it safe to flash software from a Verizon release to this phone? Will flashing a Retail Edition rom in Odin lock the bootloader like it does on the Dev Edition?
Am I even accurate in thinking that there's some kind of support file that's missing from the USC rom that allows the phone to see my Verizon SIM?
If anyone has any knowledge of these topics... please reply.
Thanks!

SUCCESS:: LTE Band 17 (AT&T / MVNO) working on G930v

Hello, All.
I've successfully completed my quest in getting my Verizon Galaxy S7 to work with AT&T's primary LTE band; Band 17.
At first I was using the PE1 firmware with root. I first used Phone INFO (for Samsung) app to access the service code 2263. On PE1, only the factory Verizon-supplied bands were showing as supported. Band 12/17 were not showing in the service menu.
I took my chances and flashed the G930U firmware (found on the AT&T S7 forum of all things) and booted the phone with my AT&T SIM card. I ran LTE Discovery and achieved profit. Band 17 was working with the same signal as the iPhone 6S the SIM card came out of.
Also, the 930U firmware completely debrands the phone, which is perfect since I'll be using it on AT&T. After I confirmed band 17 I proceeded to root using the normal method of flashing the engboot and installing the root/SuperSU package per the root instructions. I did not use the Verizon PE1 debloater/fixes .zip files to make necessary tweaks, post root. I performed the tweaks manually (wifi fix, CPU governer: interactive, and SecurityLogAgent) .. Let me know if I'm missing anything in those regards please.
The ONLY thing I can't do now is view all the LTE bands in 2263 Service Mode. I get a "RAT Selection option: is restricted".. I want to see if all LTE bands are unlocked now. If you know of another way to see all the supported LTE bands, please let me know!
I now have exactly what I was set out to accomplish and it's great. The S7 is replacing my iPhone 6S on AT&T and I will be buying a Note 7 to replace the S7 on Verizon. If/when root is achieved on the Note 7 I will do the same and replace the Note 7 on Verizon with the iPhone 7 (I cycle my personal/business phones as a guilty pleasure if you can't tell already)
Screen shots attached
nice work, thanks for taking the plunge
Just did the same on a friend's S7 that he was trying to get on Cricket's LTE, as the VZW firmware kept him on HSPA+ at most. All I had to do was flash the AT&T firmware and bam, LTE. I forgot to check what band it was on but at least it's an additional proof of concept.
Thanks for the info!
Can u link that ROM
I haven't tried with Samsung, however, most phones with Qualcomm modems can be accessed via QXDM or similar PC software. Often the so called hacked HTC modem driver will allow QXDM to communicate with the phone.
There are XDA threads detailing how to access the appropriate LTE bands and selecting bands of choice using the above method.
AT&T and VzW both use bands 2 and 4, so you probably have all the bands that you need covered already.

The factory Verizon firmware did NOT have LTE band 12 or 17 unlocked so I was only getting HSPA+ with little spurts of band 2/4 LTE every once in a while with the AT&T SIM card in it. Flashing the 930U unlocked band 12/17 for me so I have full LTE coverage in the same spots where I only had HSPA+ before.

One thing to note also is that the G930U firmware auto detects your carrier settings and has you restart after first boot. I'm assuming it will unlock correct bands depending on the carrier SIM you use. The G930U firmware does NOT, however, like the Verizon SIM. Upon updating carrier settings with a Verizon SIM installed, the device will reboot into recovery. Every time you power on the device it will prompt you to update the carrier settings and will have you reboot again.. back into recovery. Rinse and repeat. I had to refresh the U firmware to get my band 12/17 back after putting the Verizon SIM in.

The issue I have is with the U Firmware. However, the method does not trip knox. Make a Smartswitch backup and give it a go. If it still doesn't work flash back to AT&T stock and restore from your backup.
OP: if you haven't been able to allow the RAT selection i'd suggest this.
go to Service mode main menu (either broadcast cmd 27663368378 or app like shortcut master), 2. ue setting > 1. setting > 1. protocol > 5. sim > 4. EF_RAT Free Supporting > 1. EF rat free supporting on (select even if it shows on)> now RAT Free Support.
Then business as usual.

Your call is being transmitted over LTE so the data reverts back to Hspa during the call. Mine does this but returns to LTE after I hang up.

Thanks for the explanation. So at this point what is the point of this method? Does unlocking the band lead to a stronger signal?

You unlock the band that AT&T primarily uses for LTE. Much more LTE signal throughout the nation on band 17.

Sprint HTC 10 is a different animal. The bands will not unlock with the conversion and the GSM radio from Unlocked FW is not compatible. You would still need to flash the Sprint Radio back.

any advice?

I have a Sprint unlocked variant running 4G on Telcel MX, in theory you can flash another firmware variant (S-OFF, of course), but the radio must be still from the equivalent Sprint firmware...

Google around for LTE band unlock QXDM method for htc. You'll need the htc diag mode drivers and Qualcomm's QXDM program. I was able to unlock all of the US bands for my phone.

Sounds good, basic process was this:
1. Install HTC diag drivers
2. Dial ##diag# in dialer or execute adb shell commands to enter diag mode
3. Open QXDM, go to options and communications, select your device and open communications to it (don't remember exactly how to do this, it was pretty self explainatory)
4. In QXDM, go to NV-items then find the LTE configs (pointed out in the threads linked)
5. Use an LTE nv calculator to find the DEC number for the bands you want (select all bands you want and it'll put out a number)
6. Enter this number into QXDM and write it. (there are two places to enter it)
7. Exit diag mode and reboot.
8. This should survive for quite some time, any time you do a ruu double check to see if it held. Factory wipes from recovery should be fine. Using a new rom should be fine. When I wiped modemst1 and modemst2 I lost this and had to redo it.

Are you 100% sure that the sprint version can't work on verizon even with unlocking all the bands and unlocking sim? What about doing this - https://forum.xda-developers.com/verizon-htc-10/how-to/guide-convert-unlocked-to-verizon-t3380615? Or does your phone have to be officially US unlocked version to do the switch? I'm s-off, sim unlocked, using the sprint version with AT&T right now and want to use it with a verizon mvno. So is that absolutely not possible or should I just give it a shot and see what happens? Thanks

The Sprint version requires the Sprint radios are in use, otherwise it won't get any signal. The Sprint radios are incompatible with Verizon, so it can't be done.
