Mine did the same thing. I tried every which way I could and I tried different computers, ports, cables, etc but it would not take. I had to use odin and used the rooted-hroark kernal odin and now running great. I would try that. Just keep in mind you will have to manually backup contacts, sms messages, etc if you want or need to keep those. I wanted to root the normal way so that I could make a nandroid backup of my phone before doing to many mods but oh well.

 

perhaps its rooted already.
install app "superuser" and "busybox" from android market. if it works fine then ur phone is rooted.

 

i am sure u know, u have to enable usb debugging mode.

 

All of them... no seriously...

look into

1. Shabby Mod .9 ROM
2. ClockWorkMod (if you havent used the ee14 version with kernel and clockwork)
3. a custom kernel ether ShabbyKernel or Hroark Kernel (personally i am on
hroark because of ext4 support on sd card) which leads me to #4
4. Link2Sd
5. A theme of your choosing...

 

I also would suggest the ram optimization script by murderousone

 

i forgot about that...

 

yea interdpth updated kms to 4.0 and broke it

need to go over it quickly and find out how to fix it now

 

I am having the same problem trying to root my previal! I need a hotspot fast to work! My phone reboots & kms says that I should have root - but no root. I have no idea what I am doing. Can someone walk me thru this? I will donate asap if I can get it to work. Have tried 15+ times. all the commands above the 'you should have root' says failed?

 

i think it had something to do with the firmware update.

This is what it keeps telling me what did i do wrong i dont get it please help

 

I've been scouring the internet for these exact two things, but ive come up dry. :0 Is there any possibility someone could link me to the correct ones? Im really weary of messing with the wrong one.

 

I got the same message about 17 times before mine finally went through, but persistence payed off. If you can't get it with oneclick then just use the Odin EE14 with Hroarkernel and CWM.

 

What exact two things? Odin? That is located right on the Odin thread in All Things Root.

 

Yea, ha for some reason it wasn't showing up at all in the search. So, the real question is, how do I root my phone using these tools? do I flash the Odin kernal first? or is that basically rooting it? I don't know, and I don't want to follow a trail going nowhere because I'm doing something wrong.

 

I tried 7 different downloads of KMS before I was able to get it to work.

The last one that I unzipped contained an nested KMS folder and and a file called development, 20 bytes. I ran the .bat file in the upper folder, after setting it to run in XP Sp3 compatibility mode. It was finally able to write the files.

 

if you follow the instructions in the odin thread and use one of the rooted file sets you will be all set with root

 

I'm having the same problem with all of those files not being copied. In addition, I don't know how to run bat/sh or even where to find it.

After searching further I found the older version of KSM and it works fine. I was able to tether my ipad, which is all I really wanted to do.

 

hi, very new to rooting and such and I just wanted to ask.. If you do the Odin way to root your prevail does it erase all the info on your phone? Such as MISD, MEID? In other words do I have to reactivate the phone if I use ODIN?

Thanks in advance for the reply.

 

No, just your contacts and appdata etc.
