[Q] working LTE ROM - Nexus 4 Q&A, Help & Troubleshooting

is there any custom 4.2.2 ROM which have LTE working?
saw few posts about stock and LTE working on some radio versions, but nothing about custom roms;
10x

no one knows?
no ROM with LTE support? :crying:

So very few people can actually get it that its not worth devoting a whole ROM to it. The Nexus 4 can only get LTE on band 4 AWS and this exploit was fixed in radio version .48 by Google. If you live in an area covered by AWS LTE, which are few and far between right now, then there are a number of threads on how to activate it.

It's not the ROM that needs changing, just make sure you're on an older bootloader/radio and you'll get LTE if your network supports it - stock or custom

unfortunately I updated the OTA, and the LTE support is broken now
for that I was thinking maybe some smart guys figured out something

Manually flash the older bootloader/radio from the 4.2.1 system image

I9505 on T-Mobile USA

Hello
I'm thinking of buying the international Galaxy S4 i9505 and use it on T-Mobile here in the USA (rather than the T-Mobile m919 variant) ...I am aware that i9505 doesn't have HSPA on AWS band and that's fine because most of my area has T-Mobile LTE which works on the 1700/2100 MHz band (band 4)...
Does anyone from the USA use i9505 on T-Mobile and get LTE ?
Another thing, is it possible to flash m919 radio on the international i9505 to have the lacking LTE bands if any ?
A note : according to gsm arena,i9505 has APQ8064T but couldn't find what chipset the T-Mobile m919 has...If they use the same chipset it would be likely possible to interchange radios between the 2 I suppose...
Any ideas are welcomed..
Thanks
I am in same situation.
We need answer about this From the user or developer who has Experience with this case.
Best Regard to all
any help???
I9500 is the international version, i9505 is the US version

Will m919 modem work on i9505 ?
It is not wise to flash another carriers modem, but yes, you can.

Is the GT-I 9505 will work with T-Mobile LTE Band 4 after flash m919 modem ??????
If yes, how can i do that?? by Oden or By Fastboot or by recovery??

Recovery, go get the modem you want from tmo forum. and flash it, I do not think it is a good idea, but if you feel it is needed. So be it.
Thanks for the Thanks.
DO NOT flash modems. Flashing modems to enable frequencies has NOT worked on S3, Note2, S4 i337. Don't do it.
"You don't think" doesn't mean "it's not possible" or "a disaster will happen"
I used my skyrocket on T-Mobile after flashing a T-Mobile radio from Hercules (very closely related device to skyrocket... both are s2 variants)....
So please stop the useless advice of not recommended, or not advisor or such... It's xda not Facebook..
If 2 devices has the same chipset and/or the same hardware platform it could be very likely that the only difference between then is the radio software and the commercial name,. Unfortunately I couldn't find enough detailed (deep hardware details) info on the T-Mobile S4...
The main purpose here from this thread is that did anybody here try it and connected to T-Mobile LTE in USA successfully ?
Any update??

I would also like to know if the i9505 can connect to T-Mobile's LTE in refarmed areas. I'm holding out on the purchase right now but if it does work then I'll go ahead and buy 1.
As I understand it, I don't believe that the I9505 can connect to Tmo's LTE frequencies but it should probably get unto the refarmed (1900 mhz) 3g areas if you're in one of the big cities (ie; NYC, LA).
It looks from the specification that out of the box it will not work..It doesn't have the 1700mhz LTE band(which T-Mobile USA uses for the LTE uplink)..
For sure it'll need some"modding" or radio flash to work...
We need a guinea pig big-time here lol..Probably somebody buys it, flash the S4 M919 radio on it and report back...If it doesn't, ship it back to seller for a refund...
PS: it is useless if it won't connect to T-Mobile LTE(i.e. just 3G)..Pretty much everywhere will get LTE eventually...
We are still waiting for real Solution.............
so is it mainly coming down to the radio thats built into the chipset and not the software side of things, I wanted to flash the modem but I dont know if it will brick, blow up, or turn into optimus prime.... any ideas lads,
cheers

You have I9505 ? Are you on t mobile ? Do you have a good return policy for the device ? And in the return period ?
If so and you're brave enough, look for a flashable m919(T-Mobile S4) radio zip and flash it using any custom recovery ...Beware that this action might corrupt its imei or might cause a big problem that can't be corrected easily... So you're responsible for that ... But if successful you'll be able to use T-Mobile LTE and do the community a great service...,
Please let us know if you have any updates.

EXPERIMENT: Flashing the WW LTE firmware onto the US LTE variant

Recently with the delay on 5.0 for the US LTE variant, because of AT&T, I have lost my patience with them. I am looking for a way to rid myself of this BS while maintaining full stock software. I have heard that the variants of the tablet are actually not different, and the firmwares may work on either model. Has anyone tried this? I'm well aware the cell bands supported may change (but my carrier only requires one band, and the WW variant supports one of my carrier's bands). I would love to know if it works, and if I can dirty flash the package to keep my data, since the rom is basically identical.
I flashed OTA posted in general forum for LTE and using it in ATT. Unlocked bootloader, CWM, and root afterwards. I'm not quite sure what you're looking for?

Bricks.
No what i'm asking is if i could convert my device to the WW variant with a firmware flash, and thus avoid needing to manually flash OTA files becauze of delays. I know this isn't going to be the last update delayed on the US variant so i'm wondering if i can just switch the installed software from the US LTE version to the WW LTE version, without bricking.
Yeah.. I am thinking the same thing as well.
If it was possible without bricking the device, I would love to flash the "Rest of the World" firmware on the AT&T set too.

You're welcome to try it with the factory images. If it does brick, you can always restore through the same process. I plan on attempting it soon, but i am waiting on a microsd card.

Theoretically, the only thing that would be changed between builds is the GSM stack. However the OTA between the WW and the US version would not work by default. You'd need to go into the OTA zip and mess around with some of the build.prop info. Which then may cause MD5 mismatches when it is parsed, and would definitely affect subsequent OTA updates because of MD5 mismatches.
If there are Android 5.0 factory images available for the WW ROM you feel would be suitable for your geography, then this would be the safer way to proceed.
I remember when I owned a Samsung Galaxy S2, there was an XDA thread with flashable modems you could push to your device to get better reception in your area. Essentially the differences between the WW and US/CAN versions should only be the GSM stack, and perhaps some carrier-specific bundled app (like the AT&T app for example).
Just a quick update for those who are interested:
Well ... I just did it. Successfully flashed the RoW recovery image on the Shield Tablet LTE set which I purchased from US via Ebay. I'm still in the process of restoring but so far everything seems to be working fine.
Confirmed 2 things during the flashing of recovery image,
Quote:
1) Issues of Cellular/Sim Card on the US LTE set is almost certainly Lollipop firmware related. No problems on FW 4.4.2
2) Problem of Wi-Fi authentication error after sharing files via Super Beam ( Wi-Fi direct ) is also resolved after revert to 4.4.2
I think I will be sticking with 4.4.2 for now with the added bonus of file managers working on Kit Kat.

Thanks for the update. I am interested in this also.
So i'm assuming from your post you got LTE working? Which country are you in? Where do you get the factory images from?
I live in Australia and have the US LTE version. HSPA+ is good but it would be nice to have LTE working on my network (Telstra).

Actually, I don't have a 4G LTE micro sim card with me so I can't verify that at the moment. I am trying to test it out using my friend's sim card and will report back with the results. In my opinion, it's not a good idea to be trying my nano sim on this.
I'm from Singapore and the network I'm on supports LTE Band 3 & 7 and my AT&T Moto X which supports Band 7 works out of the box.
Got them from Nvidia developers website but you have to register for a free account first.

Yep I need LTE band 3 for my network which is not supported out of the box by my US LTE shield. If your network supports LTE Band 7 then your shield should also be able to access your LTE network as BOTH the US and RoW LTE shields support LTE Band 7.
So I don't think your experiment will help me. Is there any way finding out which LTE Bands your shield supports now that you have flashed the RoW recovery image?

I am not really an expert on such matters but let me try and if it's possible to find out the information you are looking for.
Why not try flashing it and give it a go ? There's the bonus perk of removing the AT&T app from the device.

Hi, I am currently using US LTE NVIDIA Shield Tablet in Singapore as well. I have successfully flashed the RoW recovery image to my tablet (since I'm downgrading from Lollipop as well, so I thought I might as well try), but I noticed that there is no baseband file in the recovery image package. I proceeded to flash anyway.
One thing I noticed after flashing is that I still am not getting LTE (half of Singapore is band 3, and my home is under its coverage). So, it's pretty safe to say that the baseband is not affected by the factory image.
However, it might also be that the latest recovery image doesn't cover the baseband, and it might be included in the previous updates. So, I'm trying to download the previous recovery images and see whether there are baseband images are there.
EDIT: baseband image is not in there. The baseband version is definitely still for North America (e1729-nala.4.05_0.6.3 @786934, notice the 'na' part?).

Sorry I don't really understand ... the RoW software cover for both Band 3 and 7 since the UK edition supports these LTE bands as specified in Nvidia FAQ.
You should still be able to get Band 7 coverage which the NA edition supports as well, right ?
Am I missing something ?

Thank you. That is exactly the information I was looking for. Unfortunately there is no point flashing the RoW recovery image if you wish to change your baseband (and then use different LTE bands like I want to).
Is there anywhere I can download the RoW baseband images? I remember they were readily available for my nexus 4.

As I said, the image doesn't include the baseband image. So, no matter what you flash on the rom side, it won't matter.
Also, about band coverage in Singapore, it's not a full overlap. Some areas are band 3 (south and west), while some band 7 (North and East). I know this from an M1 engineer friend. So, yeah, no LTE band 3 in this factory image here.
But not all hope is lost. If one day Nvidia decides to update baseband, it will then definitely include the baseband in the OTA or factory image. So, possibility of switching is still there.
Was there a baseband update with the latest software update (2.0)?
The factory images for 2.0 have still not been released.
In another strange twist when i turned on my tablet this morning I was surprised to see my US shield had LTE here in Australia. Which means only one thing - Telstra are expanding their LTE spectrum in my area!

I downloaded the OTA manually and checked the content. It doesn't have any baseband update. Also, just to confirm again, I actually re-installed Lollipop. The baseband is still unchanged (only the suffix @ part changed, but I think it's just some marker).
I checked wikipedia, and it seems that Telstra has band 3 and 28. There's a good chance that they switched your area's band to 3, or they simply add band 7 (the latter is, of course, ideal).
I read that Nvidia is preparing an update to the existing Lollipop system. Hopefully they will include a baseband update, then we can probably make the jump to the RoW ROM. For now, I'm sticking with the US ROM first.

Okay ... I see that you are not able to get Band 3 coverage. But just to confirm, you are still able to get band 7 4G LTE coverage on the ROW Rom right ?
My phone 4G LTE is on Singtel, getting pretty good coverage island wide on Band 7. Unfortunately, it's a nano sim and I'm hesitant to test it on the tablet in case in gets jammed inside the slot.
So long everything works fine, I'm sticking with ROW Rom as it will probably not have none of the nonsense whereby it require AT&T approval before release.
Sorry to trouble you on another matter, I have reported this 2 issues to Nvidia customer support but just want to check if it's just my set or an common problem.
1) Cellular data connectivity will not return after enable aeroplane mode. SIM card is subsequently not detected.
2) After sharing files using Wi-Fi direct ( SuperBeam app ), Wi-Fi connection doesn't auto reconnect due to failed authentication. Require manual intervention.
What I can say is this 2 issues no longer occur once I downgraded the software from Android 5.0 back to Kit Kat 4.4.2

According to Nvidia faq, the North American version that works on AT&T, T-Mobile and Rogers on LTE bands 2, 4, 5, 7, and 17 and HSPA bands 1, 2, 4, 5.
I see that this article ( http://www.cnet.com/au/news/telstra-expands-its-4g-services-including-the-700mhz-band-trials/ ) states that Telstra is conducting trials for 700mhz (Band 17) in your area. Maybe this is why you have begun receiving 4G LTE reception in your area ?

I initially thought it may have been the planned 700mHz expansion by Telstra in my area HOWEVER Telstra's 700mHz expansion is actually Band 28 (not Band 17) and my US shield does not work on Band 28 out of the box. Although LTE Band 17 and 28 both use the 700mHz spectrum they both use different parts of that spectrum so are not compatible.
What I think has happened is there is some LTE Band 7 coverage in the middle of town here which is where I was when I got LTE coverage today. As I understand it Telstra has some limited LTE Band 7 coverage with most of the LTE network being Band 3........ so I'll still have to wait until I can flash a RoW baseband which will hopefully give me Band 3.....

Flashing other variants?

Hey guys, I recently broke my s7e and got a check from Samsung to replace it. I'm looking for try cheapest way to do it and saw a deal on slickdeals with a comment that said:
The Sprint galaxy S7 edge can be flashed to be the 935U version, not sure about the non edge version. All S7 and S7e sold in the US have the same hardware though, so the Sprint version does already have the hardware for the 4x4 MIMO, flashing it to the U version if possible should be enough to put it on parity with the T-Mobile version on most things software wise (including Wi-fi calling I believe) and 100% on par hardware wise.
Yes just root, install custom recovery, download a tmobile rom that has built in aroma installer and you then own a unofficial ALL bands and services for tmobile s7
Is this at all true?

Well you could probably ODIN to different firmwares, but we have a locked bootloader and therefor no custom recovery. Could also try different ROMs on the exynos versions of the phone. But since they're different hardware versions I doubt you would get 100% functional software like wifi calling and VoLTE.

Yeah that would be a great idea. I know the phones are identical hardware wise. If I were you I'd do some more research to see if you could flash the sprint phone to tmobile through odin. I think it SHOULD work but having never tried I can't confirm.
I just flashed my Verizon 7 edge to the t mobile firmware and was able to use band 12, WiFi Calling and carrier aggregation. Should be the same for sprint.
Only thing I was told in the Verizon thread was that the firmware for t mobile is baseband 3 and the U firmware is baseband 2 so there is no going back until Verizon or U firmware is undated to baseband 3

Help me decide what to do now. [NOOB][VS980]

Hello everyone! I recently got a second-hand verizon G2 VS980. I live in India (location is relevant in my case because of this being a US only model). I had ROOT pre-installed and it stays even after factory reset. This indicates that it is NOT stock.
This phone has legit hardware, as in it has all VS980 components. I have checked it. BUT IT HAS THE IMEI OF A D800. Does this mean that i also have the bands of D800 enabled?
Now what i want to do is,
Above all i want this phone rooted and flashed to the latest and most stable ROM atm.
Second, i would like to use 4G LTE on it, here in India. I know that VS980 supports only band 4 and 13. I NEED band 3,5,40. I have trawled the internet for this specific info but to no avail. Does the VS980 has the hardware it takes to use other 4G bands? Or is it manufactured only with band 4 and 13 in mind? The only pieces of little info i came upon was this
jacob019 said:
After spending a few days hacking around with the VS980 (LG G2 Verizon Model) I wish to share some findings.
1. NV edits to the bands will only work with baseband 11A or earlier. All later radios have the NV values hardcoded into the baseband and any changes will be reverted. You can successfully edit the NV values, and they will survive reboot on baseband 11A, but as soon as you install a later baseband they will revert to stock. CM11 works well with 11A. Perhaps binary modification to later basebands would be possible.
2. LTE Band 17 does not appear to be supported by the hardware. I copied all the values from a D801. Android now reports my phone as a GSM model instead of CDMA which is nice, but it just won't connect to LTE Band 17. If I delete band 4, I can't get LTE at all, so I know the settings are having an effect.

and this. So i am confused where to start, i currently have a 26A baseband. Is it possible to enable band 3,5 and 40 on VS980?
I found the guides much confusing and complex relative to other devices i had. I am confused what to do first.
Should i flash TWRP first? or
Should i flash stock firmware?
I see that bands can be edited only on baseband 11A or earlier, so should i downgrade to that etc.
I have the phantom touches, and i read that they were gone after a specific update, so can i still get/flash that update with
a 11A baseband?
I do not understand this baseband, bootloader, exploits, and ROM compatiblity things.
I am willing to try even low level edits if someone is able to help and guide me.
Lastly, i just want my VS980 to run a good stable ROM with (if possible) 4G LTE on band 3,5 and/or 20 (India) and NO phantom touches update.
Specs: attached
Bump. Noone?
Can't anyone tell me that does the verizon model even includes hardware capability for 4G band 3,5 and 20? If this gets cleared, more than HALF of my problems will be gone.

This means that i can't enable/use other bands because the hardware does not exist for any band except 4 and 13. Yes?

g935v/g935t and cricket(att)

hello all ,
I just ordered a g935v on ebay a few days ago , it's still on the way , while I am planning to use circket wireless(att mnvo) on it.
As a common sense , flashing to g935u seems like the best choice , until the nougat for g935v is released recently and g935u still on mm ....
so , my question is , will it work if I flash it to g935t ? Or any advice will be appreciated.
I am worrying about the LTE BAND 17.
thanks.

Bad news :As far as I know since cricket uses AT&T there will be incompatibility issues.
Using will my phone work it says that you will have no 2G support, 3G says it will work, but 4G says "Device is compatible with some of the network carriers frequencies. It may work."
However it is missing 2 bands that AT&T uses for high speed LTE so you will not get high speed LTE so you might not get anything faster than UMTS/3G.

So you already have a 935u?
Why not just flash AT&T nougat on it until the u nougat cones out?
Someone correct me if I'm wrong but they should be able to do that, yeah?

yeah , I get my phone now , using att's rom on it , lte is working pretty well , just too many bloatwares making the phone slow as s*** , also att's rom doesn't allow me to do wifi tether, and battery runs out pretty quick...
I don't suggest to flash any provider rom on U model. You'll loose LTE-CA. You'll only have 1 channel LTE. If you want to use any carrier rom and have LTE-CA, get that carrier phone.
