Hi xda-community maybe you guys can help me with my S3 LTE. Its the german one so the gt-9105 and I'm using T-Mobile.
Everything worked great all the time with your roms here but since 3 days after updating to the newer 4.1.2 roms my LTE Internet is no more working. H+ and E works fine and it also Shows the lte Signal straight when its available but it Shows no more 4g Icon and its also not connecting to the Internet. so i have to force wcdma all the time and that sucks on an lte phone.
What is the Problem or did I something wrong? Allready tried different 4.1.2 roms and different flashable basebands but didnt work.
What can i do to get it working on that roms.
Use the correct rom then.
Every Rom in the Galaxy S III I9305 (4G LTE + 2GB RAM) Android Development section is correct isnt it? Until now every one worked expect the 4.1.2 roms -.-
Since Samsung have yet to release a firmware with 4.1.2 I would say you are using an incorrect one. Otherwise complain to the firmware maker.
I on tmobile and have a vs980. My coverage on tmobile is ok except inside my house, it's terrible. Is there a way to get the vs980 to use a d801 rom or some variant with the wifi calling in the kernel?
I'm willing to chance some roms as I have the LG support tool and can flash back to stock.
Thanks
GSM users on AOSP ROMs may experience random reboots. The problem only seems to occur when connected to LTE and switching cell towers, like when driving. I believe that many users have mistaken this for GPS problems, when in fact the reboot is triggered by the baseband. I've been using the VS980 with T-Mobile. The problem occurs on all Kitkat and Lollipop AOSP roms, but not on stock. I seem to have found a solid solution. This is a flashable 26A modem with the 11A baseband firmware:
Download 26A+11A Hybrid Modem
The 26A hybrid works with all roms that work with the 26A modem, both AOSP and stock. I have tested this one extensively with several roms and it works great. I used it for a week with zero reboots. For users with reboot issues, I recommend using a 26A based rom and this modem.
What about 39A?
I had previously posted a 39A/11A hybrid. It doesn't work--the phone reboots on incoming calls. Soon I will try a 39A/12B hybrid.
Details
The modem partition that we've been flashing is actually a FAT partition that contains many binaries. These binaries run in various parts of the SOC controlling audio DSP, DRM, WLAN, the baseband, and more. I don't know what all the parts do, but the baseband firmware is just one of these parts. The baseband firmware is a self contained proprietary RTOS that runs in a dedicated processing core in the SOC. Apparently the differences between modem partitions that make older ones incompatible with newer roms is not due to the baseband itself. The old 11A baseband firmware still works great and does not cause reboots when used with AOSP roms.
Why 11A
I was experimenting with NVRAM edits to unlock support of additional bands. I found that 11A is the last firmware that pays attention to the relevant values. All later basebands have hardcoded values that will revert the edits. It follows that the later basebands have been more deeply modified for Verizon and that 11A is a more generic G2 baseband. Other basebands may work well too, but I haven't tried it. This was the first one that I tried and it works great. I seem to be getting a stronger signal and better data speed, but it could be placebo. As an added bonus it is possible to experiment further with band unlocking.
Will this work on vs98039a stock on micromods xtream 1.1 rom?

No. That is a modified stock 39A rom. The 39A hybrid modem only works with AOSP based roms.
So is this just for GSM users? I have a VS980 on Verizon running AOD rom.. I have random reboots lol

Give it a shot, it might help. You can always flash back to your current modem. Let us know how it works out.
Flashed this on unofficial cm 12. We'll see how it goes.
Will this baseband allow me to enable LTE bands 2, 5, and 17 for usage on AT&T? @jacob019, I saw your post in the in the LTE unlock thread. Were you ever able to get LTE band 17 working on T-Mobile?
This is the post I'm referring to:

Yes and no. Yes, it will allow you to modify the NV values needed to unlock bands. I tried unlocking band 17, but my phone never connected to it. I think the hardware doesn't contain the necessary filters to support the band. Unlocking other bands may work, but I didn't have any to test.
Is it possible that T-mobile doesn't use band 17 in your area? According to this link, they only use LTE bands 2, 4, and 12 currently.

@jacob019, have you tried bands 2 and 12? As far as I can tell, T-mobile doesn't use band 17
I tried band 17 with an ATT sim. I only get T-Mobile LTE on band 4 here in Indianapolis, even with a phone that supports the other bands. Therefore I have been unable to test any other bands.
can you talk and surf at the same time coming off of LTE (without wifi of course). On a normal Tmobile headset, when you are on LTE, it'll drop down to hspa to connect to the call still allowing you to surf. Verizon model seems to drop all the way down to GPRS when a call is made if you are on LTE at the time the call is made. When in GPRS mode, data is disabled.
will this work on d802?
What's the correct stock Google ROM for MetroPCS? I don't use or care about WiFi calling.
TIA

MetroPCS uses T-Mobile's network and is owned by them. The latest build for T-Mobile I believe is LYZ28E. Although I thought I read somewhere that there is a T-Mobile only image coming that has the newest security updates that is LYZ28J or something. But in all honesty, if you aren't worried about WiFi calling, I am fairly certain you could just flash any 5.1.1 image and it will work fine.

I would use the E version. Although it is specified for wifi calling may need it for TMobile as it is optimized for their network. Not sure if only wifi optimized as the article I read only said it was optimized for their network.
If you are on LYZ28E wait for LYZ28J. Flashing LMY48I will cause problems.
You can use any of them.
I have the T 817 T (which is the T-Mobile LTE version of the tablet) but there's nothing available in the way of custom roms or anything... I was wondering if I could flash a ROM meant for the Wi-Fi only Version of this tablet...i know I obviously wouldn't have LTE access but would it boot and run otherwise?
I remember back in the days of the original Nexus 7 I could Flash Roms meant for the Wi-Fi only version on my LTE without issue.... Thanks for any input guys.
