Custom ROM with VO WiFi... - General Questions and Answers

I have tried to search through the forums looking for custom ROM's that support Voice Over WiFi (not VoIP like Hangouts etc) to no avail . I am sure there would have to be separate builds (one for AT&T, one for T-Mobile etc etc) so it might be a bit much to ask but wanted to make sure before I gave up on it !
Thanks in advance...

VoWiFi isn't really a feature that custom ROMs come with or without.
Basically if the phone's original firmware comes with it, then the custom ROM will have it.
But - it has dependencies. For example, on Samsung devices, it depends on you having the correct CSC, which is a region related file. This contains things that enable VoWiFi, VoLTE etc.
What phone do you have?

What I have is a pos iCrap 6 , it's a temp phone because I accidentally stepped on my Nexus 6 to end it's days . I am looking for my next droid and am impressed with the spec's of the Xiaomi Mi Mix 2 and the Ulefone T1. In either case I would look at a custom ROM if available. Unfortunately I am limited to AT&T or Verizon here, Sprint is meh for coverage (absolute 0 bars anywhere in or around the house and for 1/2 mile) and T-Mobile is worse, so that leaves me with the 2 hardest to get VoWiFi working unless you use their phones... More then likely going to have to go the route of in home signal amplifier to bring the signal to the basement.
Thanks for the reply, have not done a custom ROM for sometime so wasn't sure where the VoWiFi came from.

Sprint CDMA 3G ROM's

I've been reading through all these threads for a few days now and I have some questions about flashing my USA Sprint Touch Pro 2.
I don't see a ROM to flash back to OEM for the US, is this true?
I'm sure I'll run across this as i read, but if i flash my phone with a new ROM what do i need to do to get the phone working with my network again or does flashing not affect this? Do i program it just like i did before?
Will i still be able to get my Exchange e-mail?
I believe I read a few things about 3G not functioning with certain ROM's. If so are there any ROM's that support 3G?
I'm ready to bite the bullet, but I was wondering about the above.
I had similar concerns. I can tell you that there are ways to backup your ROM before re-flashing. That out of the way I have not looked back. Windows mobile 6.5 has improved the device reliablity and speed at least 40 percent. I have not had a single lockup since I flashed it. I am using the MightyROM and the only thing it does not do that the orginial Sprint flash does is the auto speakerphone and the screen off when you put a call to your ear. Beyond that it's packed with features and very stable. Including improved battery life.
I am on Sprint and have a custom rom. My 3G works without issues. You may have to install a Sprint specific provisioning cab to get it working properly. (Here is one for example)
Here is the Sprint Stock Rom it is an .exe file, so nice and simple to reinstall the stock rom.

Is there a DEV that can create a flashable zip/mod for international roms on G900P

Hey guys,
I have been noticing, ever since the MM update came out earlier this year, development has slowed to a crawl for this phone. There are a few roms that look really nice, but are not really good as a daily driver, as some have missing functions such as Phone and Contacts, and other stuff is glitchy. But over on the international G900F forums they are overloaded with different great roms with tons of support and updates and all that good stuff. And looking at the difference between the Sprint G900P Galaxy S5 and the Unlocked variant (The G900F in particular) they have 95% of the same internal components, with the only difference being the Modem to communicate with the CDMA (Sprint) and GSM (every other carrier basically) Towers. This is the reason why the roms will boot, and everything will work perfectly hardware and driver wise other than picking up a signal for the Sprint Users.
So what I am asking is if there is a Developer out there who can compile a flash-able zip or something alike that includes the drivers for the Modem and sprint Libs. Or even if there is someone who has a background in this that could point me into a good place to start, I would be glad to do it. What does everyone think about this?
my question for you is why do you want this? I only ask because i was running MOAR 7.0 for my trip to Romania and Bulgaria this summer. I spent 2 weeks in a town 5 hours northwest of Bucharest and tons of town around Transylvania and a week down by the black sea in Bulgaria and my S5 was working perfectly on vodafone, never had an issue at all. Im domestically sim unlocked, but that shouldnt matter as the SSU apk should get you internationally unlocked and ready for use abroad. That being said, none of the international ROMs would give you an unlock for international or domestic use.

I think you read the question wrong (perfectly fine, i didnt really word it very well on my part). What i was asking is if there could be a universal patch to make the Sprint LTE and Messaging and all that good stuff work on an international rom. I think it is possible as there is currently something that is exactly that, except for Verizon (the G900V variant).

Oh, my bad. Well, sprint lte isn't going to work overseas. To get lte, you'll need to do quite a bit of finagling with an nv calculator, qpst and qxdm. You'll first need to fine out what bands the carrier you'll be using utilizes, get the nv figures that they run on and make some changes to the modem you have installed on your phone. That involves getting into the diagnostic port of the device and, well, there's a whole thread devoted to exactly that. Anyways, hspa+ will work without too much effort, and hspa+ is pretty dang snappy. Messaging will work right out of the box after registering on the GSM network(+1 to gsm ) MMS and data will work also once you've entered the correct APN settings. If you REALLY need lte, then you're relegated to some tweaking, but if you can live with 5 to 7 Mbps(which is all a phone really needs, unless you're tethering for a laptop or several tablets or something like that), then just do the hspa+ thing. I was happily able to tool along quite well on that streaming YouTube, Netflix, Google map navigating, etc etc without issue. The reason there isn't a universal fix is because it would take quite some doing to maintain an app to have all those apns and so forth, but that being said, the idoneapps apk does do that for the available gsm carriers in the states. I didn't use it abroad, but might be worthwhile to ask in their forums. The admin of that site "nodial" is an Android genius! Their app costs $35, and it won't add the lte bands, but if the lack of hassle is worth it to you, it couldn't hurt to ask him. He's on XDA also with the same nick. @Nodial, does your app do the APN fix abroad too?

Tmobile customer - Safe to buy Unlocked phones? New upcoming Tmo bands?

Sorry, I'm not too much in the know, but I heard there is some sort of new update coming in the near future that will improve various aspects of the S7 like better in building reception etc.
So what do I need to be on the look out for? This deal from Target is pretty fair on top of my 5% Red Card bonus. Would this phone work with whatever update Tmo pushes out to receive the full benefits vs a tmobile puchased S7?
http://www.target.com/p/unlocked-samsung-galaxy-s7-edge-g930f-32gb-gsm-black/-/A-51032209

Nope, your link is for the international version, which won't get VoLTE, wifi calling, or updates. You want either the 930T or 930u. Anything else won't work properly.
Edit for clarification - The upcoming changes for the S7 are for more advanced LTE functionality. The extended range/building penetration are already in place, it's Band 12 LTE. The international version you linked will receive data on this band, but you CANNOT call/sms on it, as it's a data only band. The only calling/SMS that can be done on it would be on VoLTE, which you will not have.
So yeah, you'd be getting a crippled phone with none of the advantages you want.
In the last week, the rom maker below got a Note 7 port working on a 930f with T-mobile VOLTE + wifi calling + video calling. Assuming you root and want custom roms, there is an viable option in the international model.
http://forum.xda-developers.com/s7-edge/development/rom-n7-rom-port-romcontrol-t3430358
That being said for the OP:
Why target, swappa is $200 less on either model.
The international model has no US warranty.
The international model is faster with a better battery life but is slighltly weaker playing games: having both for now, completely stock, the 930f is slightly faster feeling. On the other hand, it is like night and day to compare a custom/tweaked rom/kernel of a 930F to a engineering bootloader based 930t's stock rooted rom (the custom roms seem to remove video calls)
The US model (if root matters) has a root solution that can be negated in future builds.
The international model's root trips knox, unlike the US version, reducing the resale value.

[Global ROM] MMS and Verizon - Called Verizon Support, Still Broken

Hello all,
Phone: Mi Mix 2S
MIUI: Global 9.6.4 Stable
Model: M1803D5XA
Carrier(s): T-Mobile(SIM1) & Verizon(SIM2)
Issue: MMS receiving is limited to 30kb when using the stock Xiaomi and Android Messages messaging apps. APN settings do not show on device for Verizon SIM(doesn't matter if in Slot 1 or Slot 2).
So I called Verizon and worked with level 2 tech support to try and troubleshoot this issue. Basically, the MMS and/or Device server on Verizon's end cannot verify the device and therefore limits MMS sending to the device as it cannot authenticate. This verification is done by verifying the IMEI of the SIM and the device identification.
So basically level 2 tech support cannot verify the device manually and cannot submit a request to add the device information either, it has to come from the vendor(Xiaomi) to Verizon.
Anyway we can request this from Xiaomi going forward? Seems weird to have all the bands for Verizon, can get full 4G LTE coverage but I can't receive more than 30kb per image.
I had this issue at first. Flashed latest stable and it was fixed. It's fixed on miui 10 beta and its fixed on treble builds

Well I flashed to 9.6.4 stable, which I thought was the latest stable?
I'm flashing MIUI 10 right now...guess we'll see what happens.
*Edit, still not working on Verizon. And now on MIUI 10, Dual 4G is broken.
*Edit 2, now I have Dual 4G back. Verizon needs to be SIM 2, but be the default for Internet....
I'm on VZW only and I'm on the latest MIUI 10 beta. I'm experiencing this as well. My wife receives good quality images from my phone but when she sends from her Pixel XL to me they are terrible. As are images I receive from anyone else. Kind of a bummer.
Are you guys having issues getting connected on Verizon now? I'm not able to reliably connect at all, most of the time it just sits on 1xRTT on VOICE, and won't connect to data. I can get it to connect to LTE/VOLTE by smashing airplane mode or disabling radio over and over again. Occasionally it will go to LTE, but it doesn't stay working and drops out. I can't drive anywhere and even conduct a phone call as that doesn't stay up either. When it drops, it hard drops and acts like the modem is being reset, instead of roaming to a new cell tower.
Edit, forgot to mention, called VZW, they gave me the finger and tried to sell me an iPhone XS Max 512GB as a "suitable replacement" for my 8GB/256GB phone. They were not helpful, and told me that they have "teams taking steps to make uncertified phones not work on Verizon's network for security and safety reasons". I have tried two different sim cards as well, both with active service and both work in all 3 generations of Pixel XL that I have.
Why the hell would Verizon troubleshoot a phone they haven't certified for their network? Quit complaining.

Cause I pay them every month to provide me with service. They could've atleast escalated to someone with a brain and ability to look at logging on their side and tried to help. Your comment was not needed.
I have been struggling for days with my Verizon connected Mi Mix 2s. At times I could connect with VOLTE but I lost my MMS. This past weekend I tried various ROMs with no difference. I finally cleared everything, loaded TWRP and then flashed the Global developer beta.
I also put my SIM back into a phone that Verizon would recognize and reset the card.
When I was up and running again I did the *#*#86583#*#* to unlock VOLTE and then the 4636 dial to set LTE only. So far so good. I was then able to go back and add a correct apn for verizon. With Verizon Messaging app everything is working and stable, including MMS. Afraid to mees with it again. But it is possible to get the phone to work with Verizon.

Hi - is your SIM a newer (or brand new) SIM? I am seeing something in the logging on the radio logs that the SIM doesn't contain any carrier information, and was also seeing several errors about missing CMDA specific settings. This weekend I spent most of the day on Saturday and Sunday testing build.prop edits, and messing with the apns-conf.xml file settings. I could not get anything other than 1xRTT most of the time (I modified one of the existing entries in the list of APNs to be an exact match of what my Pixel 3 XL has) and by forcing LTE Only in *#*#INFO#*#* I was able to get LTE for brief periods of time, but not consistently. On 8.11.29 and 8.11.23 builds I can't get data working consistently, and if VOLTE isn't turned on, I can't get it to even act like it's going to connect LTE. I checked the APNs and played with it for hours, but not much success. The device just seems to "connect" but if you try to call on VOLTE or use LTE data to do something, the radio appears to reset. I am wondering if someone at Xiaomi neutered something in the RIL setup for their builds that broke CDMA compatibility. When I have time again, I will do some more comparison to see if I can figure out why it's not working. I'm planning on decompiling some of the files in question and looking at the code and configurations to see if something in there is the cause. The radio logs do not have a smoking gun. I also grabbed a copy of the build.prop file from MIUI9/Oreo and I am going to compare to see if they have some kind of prop flags that are missing in the MIUI 10 builds and or PIE builds.
I am going to find a way to make this phone work on Verizon.
Eventually, I rolled back to MIUI9 on Oreo (I don't know the build off the top of my head and the phone isn't near me) via fastboot. I have been able to get decent connectivity with that software version on Verizon where I live. I had to create my own APN, and have been using that with limited success. I submitted a bug report on the MIUI bug reports page. If you want to upvote that bug, the link is here: https://en.miui.com/thread-4724630-1-1.html
Edit: I just went to lunch and couldn't get the phone to connect to anything but 1xRTT the whole time we were at lunch (I didn't force LTE only, as I haven't had to previously since I rolled back). My next steps when I have time is to compare the build.prop between the builds, but I am not expecting to find anything. I am starting to suspect from the differences in the way the logging looks that they may have messed with the code or config information for the the RIL setup in the Android before they built it.
Please keep posting what you try, I'll be following with interest! I had everything working for a while but since MIUI 10.0.6.0 mms has broken.

Can you get data and phone services? Mine won't stay connected, but that could be a hardware problem.

Yeah, data and phone have been fine so far, I think a few times it's disconnected but messing with the APN has fixed it. In general, I'd say my data and phone have been pretty stable. MMS on the otherhand, I had working for a bit on 9.6. On 10.0.4.0 it's been really slow to send and receive or not working at all. When it did work, picture quality was awful.
PS, I have my phone set to Vietnam by mistake. I have an older SIM card, at least a few years.
PS still working fine.
Mine has been repaired, they had to resolder a connector for the antenna on the board and the logic board was dropped. I saw this happen, however, signal levels are as good if not better than the pixel devices in the same spots for me, so I don't think anything is permanently damaged. I've been debating trying to order another Mi Mix 2 from somewhere or ordering a Mi Mix 3. I have built roms and have a lot of android troubleshooting experience, and I can't seem to figure this one out. What I am seeing on my device is that once it is connected, it seems to not want to roam properly. Like disconnecting from one cell causes a modem reset and then it takes a long time to reconnect. I am going to keep working on it though.

So you had a hardware issue? After the fix, which things work and which don't work for you? When I disable VoLTE carrier check, I get the VoLTE symbol, but I can't make any calls. I've been messing with the SMSC, where it seems changes aren't persisting. I can't get mms to work anywhere but the stock app, which sucks because the stupid MIUI stock messaging app doesn't have group mms >.>
I had a screen break due to it falling on a very sharp corner of an object from about 6 inches up. I took it to a phone repair place locally. They dropped the logic board, camera, front facing camera/charging interface board as well from like 4 feet up onto concrete. The person who tried to repair the screen (which I provided the replacement for) did not follow the instructions on the video either and removed the plastic lining bezel from the phone body (you are supposed to remove the screen from the bezel with a heat gun). They had to send the phone out for micro-soldering to re-place and reattach the antenna connectors for the cellular and wifi antennas. They had to pay for that. I know what the phone looks like inside from watching the videos of how to replace the screen. When they gave the phone back, there was a substantial gap between the edge of the screen and the bezel in a couple spots (atleast 3 or 4 sheets of paper thickness). I ordered a new frame, bezel and screen all in one and replaced it myself (moved all the components from the original phone body to the new one). Everything appears to work, signal levels are good, but the cellular part will not stay connected, and the modem acts like it's resetting all the time. Sometimes it will stay connected to the repeater in the office I work in for 8 hours straight with no issues, and I can text and call. When I leave that area or go home, it doesn't seem to want to roam to service, and instead of switching cell sites it seems to just reset the modem. There is absolutely a possibility that some small transistor, resistor, cap or something else on this board got damaged when it fell. Given that you guys aren't reporting issues with your devices staying on the network, I'm starting to think I need to go back and make some serious noise at this repair place. I am no stranger to working on sensitive electronics, and I was extremely careful not to damage anything inside when I moved the components (and it was already exhibiting this behavior when I got it back from them before I took repairs into my own hands).
That said, I've spent the last two days trying to figure out if I can do anything that might be helpful with QPST and QXDM as well as playing with various additional build.prop configuration. Nothing there that seemed to help. Rolling back to MIUI9/Oreo seemed to help some but was not a magic bullet. I still had to manually configure APNs and find myself needing to reboot or airplane mode every time the device should roam to a new cell site. I am planning on trying to copy the "carrierconfig.apk" file that is part of the system settings off of a Pixel 3 XL onto the Android Pie MIUI10 beta to see if possibly Xiaomi has something jacked there, but since you guys aren't reporting issues, I am seriously starting to suspect that something is physically damaged after that drop on the logic board, but the intermittent behavior and the fact that the signal looks correct and normal when it's working is going to make it nearly impossible to identify the cause.
As a side note, there's a Mi Mix 3 on it's way from GearBest....

So on mine, I can't get it to connect whether VOLTE check is enabled or not. At the office I'm like 10 feet from a repeater, and it seems to connect on LTE/VOLTE (if that's toggled on) very quickly. I have VOLTE enabled on my Verizon account. On the extender, I can make calls on VOLTE, but can't call without VOLTE enabled. I can't get it to connect to VOLTE with the VOLTE carrier check enabled, I have to shut that off and manually toggle. I am noticing massive inconsistencies in the configuration information contained inside the carrierconfig.apk that is loaded in the system build by Xiaomi. I don't see a smoking gun there, but there's a metric crapton of differences.
If I am not next to this Verizon repeater, it usually takes multiple airplane mode cycles or reboots to get onto LTE, it just sits on 1xRTT forever, no texts or data come through when stuck in that mode. Any type of cellular roaming that should happen seems to just cause a radio reset, and it goes to blank bars with X and then it acts like it can't find a network to connect to for a while or goes 1xRTT with full bars and keeps resetting every 20-30 seconds.

How is Verizon supposed to support a device they aren't familiar with? This post comes off as whiney. Verizon does NOT have to support every phone capable of their bands, that isn't up to them. Way too many variables using an outside device. With that said, running the latest global beta with the sim card out of my Pixel I have zero issues running Verizon Wireless as primary and Google Fi sim as secondary. Both networks getting VoLTE.

I expect Verizon to use the standards defined for how these devices communicate. I expect Verizon to assist with troubleshooting by providing information and looking at logs as to what my device is doing on the network. This is not unreasonable. I am not asking them to tell me how to fix the problem on a device they don't support. I am not expecting them to just suddenly support a device, but I do expect them to be willing to look at logs and information on their side and provide feedback. I am glad to hear yours is working and am starting to suspect mine has some kind of hardware damage. The local repair place has refused to do anything to help out because "if it's got a signal, it's a software problem".

Well, if it worked before the repairs.. it is definitely a hardware issue.
Check your APN settings. I had the exact same issue with my phone, especially after the latest update. I called Verizon for the customer support and they couldn't figure out as well. Then, I pretty much looked at every settings on my phone and tried almost everything, only to have the issue fixed by modifying the APN settings. For some reason, after the update, the SIM card removed the custom APN settings that I added when I first purchased the phone. Instead, it had the CBS, FOTA, IMS, LTE - Verizon Internet APNs available with the APN set as the CBS (Sorry I'm not an expert, so I really don't know what exactly they are. I suspect that those were pre-saved on my SIM cards as I have used the same one for 3-4 different phones?). Anyway, I googled Mi Mix 2s Verizon APN and set it according to the very first result I found. Since then, the MMS has started working well again. Hope it helps.

Carrier iq?

In regard to my three v20 h910's i got, and the looming february 2022 3g deactivation from att, and the fact that no custom rom supports volte (i tested lineageos, it says lte until dropping to umts when you answer or make a call).
I've got no problem working on making stock more like lineageos, i at least have that option; and that's pretty great since now i'm rocking a debloated, signature spoofing, microg oreo stock firmware (and i'm also doing the same thing with MM 6.0 on my parent's g3's because same thing).
The point is going back to stock, does carrier iq have no more lingering apk's? Is it now renamed since att purchased that company? What's up with it?

In regard to my three v20 h910's i got, and the looming february 2022 3g deactivation from att, and the fact that no custom rom supports volte (i tested lineageos, it says lte until dropping to umts when you answer or make a call).
I've got no problem working on making stock more like lineageos, i at least have that option; and that's pretty great since now i'm rocking a debloated, signature spoofing, microg oreo stock firmware (and i'm also doing the same thing with MM 6.0 on my parent's g3's because same thing).

Looks like i was good. Already got the att_iqi package removed.
I also added in a lot of extra data to your thread you quoted here that you'll most definitely want to go over.
EDIT: Looks like i was right, att acquired carrier iq in order to have carrier iq under att ownership. Many articles make it sound like att acquired and dismantled them. Yet it makes absolutely no sense why a company would purchase another in order to not use their new to them intellectual propery and new to them arm of business.
