Info 2 RUU for HTC_J15

i found this RUU
RUU_M4_UL_JB_50_Cingular_US_1.32.502.3_Radio_1.19. 40d.00.14_10.20.40.4408L_release_333483_signed_2.e xe
dose it works for (HTC_J15) CID?
if don't is there any RUU for this CID?
I'm 4.4 not rooted locked bootloader
I'm facing a lot of bugs after updating from 4.3 to 4.4
widgets freezing not refreshing sound is buggy performance is bad and more

"maybe sense 6 update will fix it but if not i need RUU to fix bugs"
