My question is simple I hope someone can helpme to figure this out.

Is there a chance to downgrade from UVUENC2 to UVUEMJC on T999 from T Mobile?

I have a lots of problems to Install CM11 on One Click and Manual. And this is fault of the new baseband.

Thanks a lot!

Yes there are certainly ways to go back to prior Modem. I don't believe that can cause issues to CM. Can you try some other KitKat Rom ?

Yep

If use the manual installation method of any custom ROM I get the Assert Failed: getprop error no matter if use TWRP 2.6.3.1 or CWM 6.0.4.5 or the newer version of those two, and if use the Auto Installer just ask me at the end of the installation "Root is missing. Root this device?." No matter if I choose YES or NO still returning to stock ROM, with a lots of errors by the way.

Updating partition details.....
Full SELinux support is present.

Those errors are on CM Rom

What can I do?

Please edit the Rom Zip file with Winzip on the pc. Do not extract the file. Make sure to open the updater script with Notepad. Its located under

/META-INF/com/google/android/

Once opened, you are looking for lines

getprop (ro.bootloader) == "T999UVDLJA"
getprop ("ro.bootloader") == "T999UVDLJA"
getprop ("ro.bootloader") == "T999UVDLJC"
getprop ("ro.bootloader") == "T999UVDMD5"
getprop ("ro.bootloader") == "T999UVUEMJC"
getprop ("ro.bootloader") == "T999UVVLDLL1"
getprop ("ro.bootloader") == "T999LUVAMB7"
getprop ("ro.bootloader") == "T999VVLDMF2"
getprop ("ro.bootloader") == "T999VVLUEMK5"
getprop ("ro.bootloader") == "T999LUVUBMK4"

You want to put a # at the beginning of each line. Or delete them out all together. Close notepad and save the file when prompted. Winzip will immediately prompt you for updating the archive. Do so. Then try flashing the zip.

If errors occur, attach the updater-script file to a post here.

Would using odin back to stock work for their issue? Maybe a full wipe off of original recovery with that?

CM and others have not yet changed their updater scripts to include this new bootloader. Not your fault. They need to catch up. You may want to post on the thread where you got the rom.

It didnt work for me, it failed. Did I mess something up?


assert(getprop("ro.product.device") == "d2tmo" || getprop("ro.build.product") == "d2tmo" || abort("This package is for \"d2tmo\" devices; this is a \"" + getprop("ro.product.device") + "\"."););
assert(#getprop("ro.bootloader") == "T999UVDLJA" ||
#getprop("ro.bootloader") == "T999UVDLJC" ||
#getprop("ro.bootloader") == "T999UVDMD5" ||
#getprop("ro.bootloader") == "T999UVUEMJC" ||
#getprop("ro.bootloader") == "T999VVLDLL1" ||
#getprop("ro.bootloader") == "T999LUVAMB7" ||
#getprop("ro.bootloader") == "T999VVLDMF2" ||
#getprop("ro.bootloader") == "T999VVLUEMK5" ||
#getprop("ro.bootloader") == "T999LUVUBMK4");
