I recently rooted my phone but was unable to find a custom recovery. I just found this post which I followed. If you don't want to click on the link it basically says to put a .img recovery file on your phone and run android terminal to install with this code:
dd if=/sdcard/twrp.img of=/dev/block/mmcblk0p21
After doing this the phone shows this message: secure fail: kernel along with a larger message start up fail and it tells me to use verizon software repair assistant. That doesn't work.
What can I do? Thanks in advance.
