GSM on XT907 Lineage Rom? - Droid RAZR M Q&A, Help & Troubleshooting

I'm moving to Australia soon and need GSM to work when I get there. My RAZR M was unlocked when I got it (mobile network settings were set to global) and I was wondering is GSM worked by default or if I had to change anything before hand. Any reply would be greatly appreciated. The only thing I've seen is an APN xml file for 4.0-4.4 but I doubt it will work since I am out of that range (6.0) and there are no APN settings even present in the Lineage settings menus. I need it to work with Telstra.

Nothing? really?

[Q] wifi tether / mobile hotspot

Does the froyo mobile hotspot works on an unlocked Droid 2 global? Let's say in Chile with a chilean SIM?
(On my nexus one using 1900 mhz Entel Chile works well)
Yes, buid in one works fine.
But you need to create APN for the tethering "dun" type.
D2g will not let you create it manually due to Verizon restriction but you can use app from market (apn backup restore) to backup existing ones, edit on your computer to add the type, then restore. Works perfectly on my Rogers Droid 2 Global
You don't even need root to implement the 'hack'. If you have root, you don't need any app, just edit straight on the phone.
Sent from my DROID2 GLOBAL
Leobg would u be so kind and briefly tell me the procedures to get that mobile hotspot working on my d2g with Rogers? I dunno what that dun type is, I tried googling it but failed thank u very much in advance!!

Data will not work after flashing G935U Firmware on G935V

So Im looking for a way to enable native tethering on my phone and after a lot searching I flashed the G935U firmware. After flashing the G935U firmware on my G935V, my data stopped working. Call and text works fine but no data. It doesn't even show the 4G LTE symbol in status bar.
I am currently using Straight Talk BYOP.
Any help would be much appreciated and thank you!

Thats the crazy part! I cant edit it after flashing the U firmware. But the APN settings are the same from when it was still on the V firmware. Its just now the 4G LTE doesnt work. I downloaded some 4G enabler from the play store that took me to some hidden settings to change between GSM, CDMA, and about 12 other variants of similar nature. After doing so the only one that worked was the CDMA (prl) which activated 3G network. But LTE CDMA (prl) didnt work which was what it was on I think.

add a new APN with tour settings. emable it... and try global mode
Nope still no go...its not even showing 3G at the momemnt
I tried every apn/preferred network type combination and wasn't able to get anything better than 3G. So I just got done flashing the G935V firmware back and now 4G LTE is working. Anyway I can use hotspot on G935V firmware?
SOLVED!
So after contacting straight talk it seems my APN settings where to blame.
Upon opening the APN, I had to change APN from "vzwinternet" to "tracfone.vzwentp." Then save and make sure network mode was set to LTE/CDMA instead of global.
I noticed it returns to default "vzwinternet" after flashing any firmware thus making me have to put it back in. But that's no problem at all. Everything is currenly working and I now have tethering THANK YOU FOR THE HELP

G935V to G935U for AT&T
I have the Verizon S7 Edge G935V working on straight talk with their AT&T sim.
Had to change from CDMA to GSM then add the new APN settings.
The problem I have is the G935V doesn't have LTE band 17 which is used in my area.
My Nexus 5 with same sim using LTE Discovery app confirms band 17 but with S7 Edge G935V
I don't get it but a different connection and its very weak.
I would like to give this G935V to G935U a try. My S7 Edge G935V has Android 8.0
I have downloaded ODIN, Samsung S7 Edge drivers, and G935U w/Android 8.0 (AT&T) July 24, 2018
Has anyone done this recently on a G935V with Android 8.0 on it?
Will I get LTE band 17?
Do I loose any CDMA capabilities should I want to try it?
What's the down side of doing this?
How would I continue to get updates?
Thanks,
Ken

How to unlock network bands on Verizon unlock phone ?

Hello everyone so this my history I'm on T-Mobile Network and I have a Verizon v20 unlock phone everything working good just the internet is slowly so I searched about how to enable bands (I can't find something clear ) on Verizon v20 to make it work on TMobile (full LTE ) its this possible ? Is there some mode or something the really work (Unlock bands) like I said already searched but I can't find something really clear
Note : I have just H sign allway on like other user experiment jus show 4g lte for a minute
Thanks on advance
If I understand you correctly, perhaps you need to set up an APN for T-Mobile. It'll be under Settings->Networks->More->Mobile Networks->AccessPoint Names.

Well I already have the TMobile APN and I trying to figure how to get lte because I have only H icon and no Lte (speed) so what the asking is if is possible activide TMobile band like 7 , 12 etc ... Thanks for your reply ?
Well, you came from Verizon CDMA and T-Mobile is GSM. As long as you've got the proper values in the T-Mobile APN (and you got your sim from T-Mobile), I'm not aware of anything else you can do. Could be wrong, though.
Good Luck!

Thanks I'll keeping searching if I find something I'll post here but if someone have a information about how to making work (unlock frequency's band ) more than welcome ?
The ONLY way I could is to flash another carrier or us996 custom rom. The vs995 rom apparently forces the phone to connect to Verizon towers and bands only. Can't edit in any secret menus, nothing, that's the only way I could. Tip, if you want to use wifi calling, flash a custom stock TMobile room not us996
Interesting so there is a way to flash us996 (Spring correct ?) rom on V995 ? Anyone know what's the safe way if is possible ? ?

Flashing a tmobile rom on a nontmobile phone is a great way to brick. Best case it won't boot and lets you flash back, though it could trip ARB as well making it impossible to roll back. The kernel uses a different security key than the other models.
Has anyone tried flashing a Non.Hlos.Bin from which-ever carrier you are wanting to use?
I don't own this phone, I just by chance took a look at this thread.
Yes of course you would need the correct APN. But you may also may need to flash the modem file from the carrier you are wanting to use. ( It can be extracted)
Another option is using QPST.
With QPST you can change the IMEI, add bands, repair a bricked phone, flash a rom etc. These are just suggestions for things to try. Again, I do not have this phone.
Old thread I know, but if you or others have this problem, have you tried using the LG hidden menu (accessed using dial screen)?
*#546368#*996#
If you have the 996 version, just copy & paste. Otherwise, just change 996 to what model you have.
Field Test > Modem Settings > LTE Band Selection
Select the band you want to use/test, then wait a few seconds for it to register. Your signal will drop for a moment, then should show 4GLTE, if you selected the correct one. There may be more than one that works, but one may be more congested.
You should find a list of available bands for your carrier, before messing around.
Also, do not mess with other settings, or you could really screw up your phone I know from experience.

Strange Network Issues With Unlocked SM-G935P (Sprint) on MetroPCS

Hey guys, I could use a little help here. I've done some firmware flashing on phones years ago, so I'm not a total noob, just haven't needed to in a long time.
Anyway, I recently picked up an unlocked Sprint S7 edge (was a really good deal) and I'm trying to use it with Metro now. The issue is this. If I set the network to GSM mode, I can make phone calls just fine, but data is totally not functioning. If I switch it to LTE/CDMA mode, the data works beautifully, but I can't make or receive any phone calls. It just instantly hangs up if I try to dial out or goes to voicemail if someone calls me.
I've activated the IMEI with my carrier and verified that the phone is indeed unlocked. I'm guessing this is just some annoying Sprint bug put in there to make the phone not work right on other providers. Any ideas what needs to be done? Do I need to run a third-party ROM, flash a different modem to it? Something else?
I really appreciate any tips here.
What firmware is the phone running?

Hi Ivpre,
Thanks for responding. The phone is running Software version G935PVPU6BRD2, baseband version G935PVPU6BRD2, it's HW revision 7.0 and Android 7.0. Kernel version is 3.18.31-12623509.
I've tried using a few SM-G935U ROMs but they all have failed so far and left the phone in a boot loop. Only by reflashing a Sprint ROM am I able to successfully flash it.
I assume I'm just not selecting or finding a ROM that the same or newer version, as I've read about the downgrade issues with the bootloader. Any idea how to match one? I'd be fine with pretty much any ATT/T-Mobile/Metro ROM since that should fix my issue for the time being. A factory unlocked ROM would be nice though.
I have a T-Mobile Sim (same network Metro uses) in my unlocked Sprint S7 Edge. Network mode is set to Automatic and everything works fine.
Did you Add the APN for T-Mobile? I had to add the T-Mobile APN https://support.t-mobile.com/docs/DOC-28006
And the ALSO add a second APN named internet, with no other values changed. The 2nd one is the one selected, not sure why, but it works that way.
I would like to flash a T-Mobile Rom or the U Rom but they are on Baseband 4, which will not work since our phones are now on Baseband 6(5th number from the right in the firmware version.)
Did you try changing the APN settings?

So you are using the Sprint firmware on T-Mobile? Everything works well? I'm thinking of jumping to cricket this summer, but one phone is stuck on b5 (the other is still rocking 4), so I was a little worried. So basically you just put in the SIM card and added the APN's?

Yes it was working fine with a T-Mobile Sim card and edited APN's. It is now back on Sprint because T-Mobile coverage is poor/non existent inside my work. I will be porting one of my SERO lines to T-Mobile but keeping one with Sprint. T-Mobile only uses Band 2 and 4 where I live, If you live somewhere that has band 12, it may not be unlocked in the Sprint Firmware.

No Mobile Network Data on Custom ROMs

Hello,
I've gotten my phone's bootloader unlocked, TWRP installed and have been flashing the available custom ROMs with no success to getting my mobile data to work. I don't have this problem running the stock ROM or MIUI.eu (which I'm currently using). I prefer to run the Lineage based ROMs if possible, but I cannot get the mobile data to work on any of them.
I've got into the APN settings on the phone to see what's up there, but I can't change any of the settings, they're all greyed out. I can change the APN settings on MIUI but it works fine anyway. I think the APN settings are wrong on the custom ROMs and would like to change them so they're right, but I can't do anything about it.
I'm with Virgin Mobile Canada, which uses Bell's network. Any Virgin users on here or anyone else have this problem?
