I have a att s4 sgh-1337 with android 4.4.2. baseband version 1337UCUFNB1. I'm trying to put on CM 11. or another rom that looks like stock android with no touchwiz and 100% working and stable. if I downgrade to android 4.3. can I then root, install CWM recovery, and install CM 11?

what would happen if I booted into android system recovery and installed the cm 11 rom for my phone?

Short answer: No. You'll void your warranty and bootloop.

As for 'stock android look', I can recommend PurifieD or Google Play Edition ROM although it has a few bug that I'm going to work on once this semester ends..

No CM for now. You cannot replace the stock recovery. The only working recovery we have is safestrap.

You can use DVKM Tool and install BlackBox3.0 (Check post 3 of All things ATT thread)

thanks. hm, don't know what I should do. I bought this phone last week used on ebay so I dont think I have a warranty to void. another reason I wanted CM is so i could easily get updates. I dont really want to be messing with roms all the time. do you guys think cm will work soon? in the next few months? maybe I should stick with what I have till that happens. I'd rather wait for that then cause my self more headache.

does PurifieD come with the stock kitkat widgets?

No, probably not. The i337s bootloader is locked so we can't flash kernels. A lot of devs have moved onto newer devices so I doubt anything new will happen. And I'm not sure what the stock kitkat widgets are.

what android version would the i337 need to have to be able to install cm 11? 4.2.x ? I'm thinking of asking the guy I bought mine from to see if he has any others that still have an older android version that would let me install cm on.

You'd need 4.2.2, mdb or mdl bootloader and firmware

Yes, it'll update on its own unless you root and delete or freeze the system update app.

Or it might have MF3. To find out, just go into Settings > About Phone (if the phone is complete stock unrooted, then the build number/baseband should match the boot loader)
