I was trying install CM12.1 ROM for Galaxy S3! [Android 5.1] on my existing CM12 [5.0.2]. I followed this article and installed http://galaxys3root.com/galaxy-s3-roms/cm12-1-rom-for-galaxy-s3-android-5-1/.
I did install ROM and GAPPS. Now It is bootloader loop. it is coming all the way to Optimizing apps and reboots again. I think is almost softbrick. I cannot access SD card in my computer to push new ROM or change ROM. What are options I have ?Anything I can do with ODIN? please provide me some steps.

Today I tried again on CM 12 and 5.0.2 with [ROM][Official]CyanogenMod 12.1 Nightlies for the Verizon Galaxy S3 (d2vzw) and http://wiki.cyanogenmod.org/w/Google_Apps . Still it is the same.
It is on boot loop "Optimizing app.." and then rebooting again. I don't know the solution to fix.

Its very possible 5.1 won't work on the S3. I would never follow some random link. XDA is reputable but other sites very well may not be. I still have my S3 on 4.4. My Nexus runs 5.1 fine but then again it's made to run the newest firmware

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.
Hello,
I keep trying to update to the latest nightly to get cyanogenmod 12 on XT1302. However they don't work. I get weird scan lines, even during the boot logo and animation. Everything is slow and unstable. During installation it always says root access possibly lost, fix, yes or no. Thankfully I have a working backup, but it's stuck on an old 2014 cm 11 snapshot and I want to upgrade
I suspect there is a problem with gapps since I get incessant "X app has stopped working error" messages and it's always a google service. However I do not know what the procedure is. I downloaded the cm12 gapps and flashed them after flashing the nightly as said in faq but it doesn't seem to work. Sometimes even Trebuchet stops working, making the phone totally unusable.
Any help would be greatly appreciated. :good:
Are you running with a lollipop bootloader? I think the latest CM12 requires it.

I've been googling this and I think you have correctly identified the issue. If I install the lollipop bootloader, will I be able to go back to my cm11 backup in case of an emergency?
Just to confirm, to update the bootloader, you have to flash the brazil lollipop rom and it should work?
If you unzip the stock ROM, the bootloader is the motoboot.img file.
I don't think you need to flash everything, just the bootloader file. If that doesn't allow you to use CM12, you may have to restore your CM11 nandroid and then flash CM12.
So i've been running stable slimkat 9.0 (4.4.4) on my galaxy s3 and it has been working great. I want to upgrade it to lollipop but I've had trouble flashing any lollipop rom. CM12, AICP, OctOS, PacROM all fail to boot after I flash in recovery. The boot animation starts, and I get the screen that android apps are initializing. After it runs through the apps, the screen blacks out and the phone resets and the cycle continues.
I've had no issues flashing roms beforehand. I can go back to 4.4. and 4.3 ROMs both AOSP and Touchwiz without any problems. I've flashed with both clockwork mod and TWRP and the results are the same. I do a clean factory reset and wipe prior to flashing the rom and 5.1 gapps.
I have no idea why it won't boot up for me. Would appreciate any help!

Are you on the correct firmware? MF1? There is a flashable zip in the CM12.1 thread for it.
Updating the firmware did the trick, thanks! Was running on ML1 up til now. Glad my s3 can still keep up with the times
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
