[Q] Samsung Logo Stuck - Advice Needed topic

Samsung Galaxy S5 G900A (AT&T)


Previously on a day off I became very bored, and decided to root my phone. After playing around with everything for a day i did not like it. So i just went into recovery mode and did factory rest on my phone. Now I used supersu and a basic root everything worked perfect after i rooted it. But once I tried to put the stock firmware back on my phone it started acting funny. With showing Unfortunately Context Service has stopped. It was so absurd my phone couldnt function properly. I tried flashing the stock firmware on there in hopes that it would fix my problem, but it only made my phone completely inoperable. I have been trying multiple ways to fix this using odin v3.09 and odin v 3.10.6. Here are some of the files I have tried to get my phone back to stock. (G900AUCU1ANCE_G900AATT1ANCE_G900AUCU1ANCE_HOME.ta r.md5) I have tried downgrades. Odin seems to fail on every single one besides this set up (AP_G900AUCU1ANCE_964333_REV00_user_low_ship_MULTI _CERT.tar.md5) (CP_G900AUCU1ANCE_964333_REV00_user_low_ship_MULTI _CERT.tar.md5) (CSC_ATT_G900AATT1ANCE_964333_REV00_user_low_ship_ MULTI_CERT.tar.md5) Odin loads those three files onto my phone perfectly with in 3 minutes but after they are installed on my phone. When i power it up it gets through the first screen and only shows half of the samsung logo freezes and goes to a black screen with a blue light. I have been working at this problem for a little over a week a couple hours a night and i really can not seem to make any progess. Help would be greatly appreciated.
