[AT&T Samsung Galaxy S II SGH-I777] nakedninja42:
6/20 UCLE5 stock build-05/31(sammy)/CM modems & stock LE5 files for Mobile ODIN flash

I am not exactly sure how this slipped by the community but I found UCLE5 for I777 today! I am extracting all the content and I am starting first with the modems. I have already flashed the one I made for Samsung Roms and attached it to the post.

Attached new screenshot for first speedtest. 7 tests with average dl 7877 kbps up 905 kbps. Average before was dl ~6000 kbps up ~500 kbps in San Jose, CA.

Here is the info from build.prop

This is mostly stock LE5, I removed bootloader and changed the stock kernel to AJ Newkirk kernel (build date 05-11-2012) based of Entropy512 sources. I used Mobile ODIN to flash with root.

Download zip for cache.img, hidden.img, factoryfs.img, modem.bin, and AJ Newkirk kernel and flash using Mobile ODIN for ICS and root

Remember to hit Thanks if I help!

I want to give credit for RockRatt and his zips, I used a previous packed one to create the LE5 pack.

Thanks to tylercarter for testings CM version, it is now added to the post for download!
