I just recently flashed Dubbsy's Google Edition port, and everything is working spectacularly well except for LTE. I've read through all 60-something pages of his ROM Thread trying to make it work (following the instructions of the LTE on/off app to a tee), but I'm all out of ideas. Even worse, when I flashed the latest CM 10.1 nightly, I still had no LTE, just a 3G signal. Any ideas on how I can make LTE work again? I'm really hoping I don't have to start from scratch by flashing the stock firmare in ODIN.

Hello, I have the "4g" flavor white back T-Mobile version of this tab and with there being different flavors of the 10.1 I am not sure which rom to use. After rooting the phone and getting revovery installed CM downloaded and installed the wifi version of the rom. I thought I found the nightly thread of the tmo version but revovery wouldn't install it saying that the build version was wrong. So I have gone back to stock until I can get this issue cleared up. I think my build prop may be wrong in the device because com.phone.android force closes on boot on the stock rom (I think I need to reinstall stock). But I am still not sure which flavor of the rom to install. I want the CM ICS.
I am not new to installing and using custom roms. I have been doing this since the MT3GS and have been using CM on that since Froyo. I am currently using MT4GS and currently have the CM ICS alpha 4 on it. I am just a bit confused at this point since it is not cut and dry.

I have this one on now There are also CM9 nightlies on the CM site I believe but no issues with this other than camera. There is a camera patch also that makes the back camera work.

Here is the thread with the camera patch.

Not sure why not many people help on this device it's a very nice device and works great on the T-Mobile network but anytime I ask anything no one ever really answers.

Thank you very much!! I think I have the wrong recovery installed which is causing all my issues. It is seeing my device as a wi-fi only device and not a tmo device.
I just got home a few minutes ago, and I had the wrong recovery installed. I got the right one in and everything is going swimmingly so far. Thank you again!
I wish there were subforums for every flavor instead of everything all mixed up. It makes it confusing when you are dealing with 80 different versions of the same device.
Im new to flashing roms but have a slight idea as to what im doing. I am looking for a 4.4 kitkat rom specifically for the tmobile version (sgh-m919) of the s4. Or if there is a specific process to making it work with that phone. I installed the google play edition that I downloaded from XDA but had serious signal problems that weren't present with the stock rom. I then installed the cyanogenmod version and the signal problems went away and everything was going fine then suddenly my google apps stopped working for no apparent reason. Can someone help my greenhorn ass??

have you wipe everything when flashing the CM ?
and use the 4.4 gapps ?
First of all this is my first post. Hello to everyone. I have been searching/reading thru these forums. Great source of info.
Phone info:
Currently S-OFF, unlocked, lateset AT&T 4.4.2 firmware, viperone 6.2.1, twrp
I have a pretty good comprehension of how to install or revert pretty much anything that can be done to this phone and have done so with great success. What I don't understand is the relationship between the firmware base of an RUU and the build of any given ROM. How is it that a custom Rom based off let's say x.xx.401.x work with x.xx.502.x main version? The devs say to update to the most current available firmware. Does that mean I have to flash a firmware base that matches what the Rom base for optimal performance? Because I originally thought that was the case and when I did my phone developed syncing issues particularly with the stock mail and weather apps. They would only sync over WiFi. Everything else about the phone worked as normal. Believing there was a problem with the Rom I flashed a few different popular roms on here. Always returning to full AT&T stock first. I later fully converted to GPE and to my surprise everything worked as normal. So I then converted to stock developer edition by way of zip flash and RUU exe. (By the way, when I say stock I mean s-off & unlocked but otherwise factory.) Received all the ota's. Main version would show as x.xx.1540.x. supposedly this would make my phone a dev edition with AT&T as the provider. And yet the syncing problems returned. So once again I returned back to factory AT&T 4.4.2 and all returned to normal. I then decided to try and use a Rom based off 4.4.2 and not one from 4.4.3; expecting the syncing issues to return only this time they didn't. So now I am really confused.
My questions are:
If coming from 4.4.2 factory firmware, is it best to run a Rom from the same base or am I doing something wrong and I should be able to use a Rom from a newer base on an older firmware?
If the developer edition and GPE can be carried by AT&T then why was I having syncing issues with the developer edition and not GPE?
I thought by being s-off I should be able to flash any RUU from any carrier without problems, just that I would be limited to the network capabilities of the actual service provider.
Everything I know about this stuff I learned from this forum. But I think I missed something.
My AT&T M7 always works best on the stock software.
The only thing I could figure is that AT&T have refined the software and radio so well that all the other versions pale in comparison.
I noticed the Developers Edition always had a horrible Bluetooth and WiFi radio. Signal strength was always weak compared to the stock AT&T software.
To answer your questions
Flash any version Roms you want on the latest AT&T firmware. And you'll have the best your phone can be.

I get so mixed up with all the terms being used interchangeably. So to clarify, as long as I am using the latest firmware from AT&T (currently 5.12.502.2 kk4.4.2), I can flash any custom ROM base. Whether it is based on 4.4.2 or higher. Correct?
I still want to know why I experienced the sync problems while running the factory x.xx.1540.x dev edition but not with the GPE. I never tried the factory x.xx.401.x WWE firmware either. However, I just got an sim unlock code from AT&T earlier today. I'm gonna try that maybe tomorrow and see if it makes a difference altho I don't believe it should. And I'm not gonna switch to a different provider.
Honestly, I was happy with my phone before I got wrapped up in all of this. I just decided to tinker with the phone and the mod bug has bitten.

I think I figured this out. I continued to flash different ROMs and firmwares with the same results as I posted in the OP. Then earlier tonight I decided to try to convert to developer edition again (x.xx.1540.x) and flashed an ruu.zip, went thru the setup process, and as before the same issues returned. Then I had an idea; lets try something I haven't done yet. I pulled the SD card and factory reset the phone. After I completed the basic setup process I inserted the SD card and let the phone do its thing. The phone now works as it should (same as it does with the AT&T xx.502.x firmware installed).
Just figured I would pass this along.
Cheers
I give up
I thought I had this figured out. Last night after to converting to dev edition with all updates, everything seemed normal. I flashed the latest viperone rom as it is the rom I want. Turn the phone on this morning and the sync problems are present once again. I have searched thru a tom of pages on this sight alone. I cant find an answer. So its back to stock at&t.
I solved the problem. Incorrect settings in 4636 menu.
In it's current state, Lollipop ROMs crash/hang/reboot when trying to use the GSM network on the N900P with a ROM made for it (hltespr branch).
The solution:
Flash TWRP for HLTE
Download a rom for HLTE
Flash the rom in TWRP
Flash GAPPS
Install Messenger from the Play Store for texting to function
Testing and confirmed working on the latest CM12 nightly. Have H+ on T-Mobile.

Umm... Either you are missing a step here... Or you are not explaining correctly.
I am a GSM user, and Lollipop roms crash at the modem level... Due to not being able to use the newer basebands of course. You are saying that in order to make it stop crashing, to download the lollipop rom, and flash it. That is the thing that causes the issue.
So if you could please help me with this confusion, just for the sake of the topic, I don't really care about actually getting it to work
Think he means 1st flash stock then custom rom?
Until just recently, i was on lollipop using att. I was on the MI3 firmware as needed for the gsm domestic to work. All i did was start on stock 4.4.4 flashed the baseband needed made sure it was working on the stock rom then i did a dirty flash on over the stock rom. Had to use titanium back up to wipe the apps that continued to fc. After i got all of them it work like a charm. Just switched back because i wanted a more stable rom.. so stock for me until lollipop stock is out.
Hey folks, am thinking of getting an LTE Nexus 9 now that they work on Verizon.
But it seems all the good custom ROM's are for the WiFi version of the tablet.
How hard is it to get the LTE working if I were to flash a WiFi ROM on the LTE tablet?
Most specifically, I like the AICP ROM's and SLIM (if they ever return).
I don't guess it's as simple as flashing a modem, huh.
