here is my question. i was doing this process step by step. after step 5 i dont know what i did but my phone got messed up. when i turn on the phone it goes to htc screen and in the bottom it says this is for development only bla bla bla. but my phone is not going any further. so i decided to redo everything and start again. so i download RUU but RUU is not restoring my phone after 3% it says error 155, pleas download correct RUU. i contact HTC they told me that i have downloaded the correct RUU. i have wiped whole phone in recovery mode. i have formated memory card as well. and then i have tried to redo everything from step 1. but nothing is working my problem is still there at HTC screen. any idea what went wrong and what can be done?

hi, i am totally new to this stuff. i have a question. in first step you said now type ##3424#. where do i type it? hi, sory for my previous comment. figured out after i start doing it. but now i am stuck at step 5. you said install root explorer from play store. but after step 4 when i restart my phone it started as a brand new phone and trying to setup for first time. on the screen it shows that "HANDS FREE ACTIVATION ... CONNECTING NETWORK." so i cant reach play store to install root explorer. i am sure i did first 4 steps and everything went well. either i am doing something wrong at step 5 or i have done something in last 4 steps. can you help me pleas? also now when i start my phone it goes to HTC logo screen in the bottom it says in red font that this development purpose only bla bla bla. and phone gets stuck there i cant even power it down i have to take the battery out to turn it off. i dont know whats going on i never done anything like this before. but i did follow all the directions as you posted. i am not blaming you for it i am responsible for what ever is happening . but if you can help me fixing these issues i am having i'll sure appriciate it. thanks
