[Completed] My t999 s3 doesnt want to install cyangenmod

i had cm10 installed but after a few months of problems i decided to upgrade to cm11. After trying to upgrade to twrp 2.8.3 something happened then my cyangen was tripping balls so i went back to stock s3 4.1.3 by flashing with odin. Then i rooted my s3 again using odin. Then i installed rashr and installed twrp 2.8.3. Then i booted into twrp 2.8.3 and before twrp loaded it had the cyanogen logo on it.Then did factory reset and the davik cahce clear thing.

Do you mean this unofficial CM11: [ROM][4.4] CM 11 Unofficial - Beta 7 11-22-13 (Discontinued due to new device)?
Or this one: Cyanogenmod CM11?
Please check this thread: T999 UVDMD5 Firmware / Bootloader.
According to this, you might have to update some files (bootloader, modem, etc.) to be able to install newer CM versions.
AFAIK, only CM10 is officially suported for your device: [ROM][OFFICIAL] CyanogenMod 10 Nightly Builds for SGH-T999.
If you have further questions, please ask in the T-Mobile Galaxy S III Q&A, Help & Troubleshooting.

Thread closed and thank you.

[Completed] [Q] help cm 10 bootloop for gts7500

Hey guyz,
I have an issue with flashing cyanogen mod rom. I hav cwm recovery.Flashed zip.
But after flashing zip and rebooting system a white screen fades,I found fix also for that.
Just placing stock boot.img from backup but after doing that also i have a problem.
The mobile boots,samsung.com logo comes out,then gts7500 comes for 5-10sec and the
mobile reboots.Endless loop.i have done flashing it many times,did wipe data/cache and
dalvik cache but still no difference.
But one thing i observed that i am able to flash roms which have same android version ie.
2.3.6 but im unable to upgrade to higher version like 4.2 or 4.4
Tried flashing even slimbean and speedmod rom but same problem.I have an indian firmware.
Current OS is inspiration rom v_18 by kk9999gada..
So guyz anyone have an idea to get out of this bootloop? I badly want to use cyanogenmod
and upgrade its version

Hi, thank you for using XDA Assist. You are probably going to have to start all over and flash the stock firmware in Odin. Also, the version of cwm may have to updated to flash newer roms. But the best place to get help is in your device's specific forum here, http://forum.xda-developers.com/galaxy-ace-plus They are the experts on your device.

Cannot Boot My I9100

Hey guys. I have a Samsung Galaxy I9100 and without any experience I tries to upgrade my firmware to Lollipop today. It was a disaster. Now I'm stuck in Cyanogenmod 12.1 5.1.1 no installing GApps and no booting, no flashing rom. I cannot install any applications on my phone. I suppose I did something wrong about recovery,but not sure. For this issue, do you guys have anything to suggest? Thanks.

Download the firmware for your phone from sammobile.com and flash using the Odin app for windows using the instructions here.
From this flash custom recovery and try again to update to lollipop using Cyanogenmod files

i dont have any experience with your device, but you may want to review the roms thread and see if they mention upgrading the bootloader and/or modem. cm 12 is a good bit newer than what you have on, and those things commonly need to be upgraded.
check before you try it and ensure you need it or not, im just stating general facts
