mobile

I've rooted phones in the past to remove bloatware but I claim to be no expert in these matters. Today I rooted my phone using the method that QBKing77 outlined in his thread. The root worked fine so I then proceeded to move forward with unlocking my mobile hostpot functionality via the QBKing77 YT video which consists of replasing two service files .jar and .odex. After those two files were placed the phone will not boot past the Yellow Sprint screen. Any help would be appreciated in overcoming this issue!

Thank you!
