help unlocking NAND after using unrevoked

I'm a noob at Android hacking and wanted to root my evo After a few questions to one of my friends, he pointed me towards unrevoked3. Now am stuckand don't now how to unlock the NAND and its driving me crazy. I want to be able to use roms such as damage control. Please help. Im compleatly lost.

I would ask your friend, don't think many here use unrevoked, we used the complete method from toast.
Also read through the posts in the Dev wiki.

I just rooted and unlocked last night...had a few issues. Should be around most of the evening. Where are you and what did you do?
Last night I used that unrEVOked3.1 software and then moved on to unlocking. You will need to ADB installed to do it the way I did it. This is a component of the Andoroid SDK. (You can find that from the google android site.) It is complicated and I got through it because I am old enough to have actually worked in DOS back when there were dinosaurs.
It's not impossible, there are instructions out there...but it will take effort. Hate to point you away from xda...'cause LOTs of good work here...but I followed the unlockr.com tutorial for unlocking nand.

There were a couple issues where su couldn't find the sdcard. I even did lists and saw it, but the commands failed at start. Took a mix of unplugging usb and replugging and mounting and just charging....not sure what fixed it...LOL. But I got the commands to run eventually.

You can use Rom Manager app to install CM7. In fact Rom Manager is included in CM7 Rom. Honestly I think Rom Manager was made mostly for CM Roms. Make sure you wipe data, cache and davlik before going to CM from another Rom. I never flash through Rom Manager app and always flash manually from recovery, but a lot of people do flash through Rom Manager. Good Luck.
Also just to clarify(someone correct me if I'm wrong),
I think if you used the unrevoked3 app from this thread Unrevoked to root your EVO that it also nand unlocks it too. The thread doesn't state it, but the app has been updated to work with the latest hboot, so it should work on all Evo's right now. I could be wrong, but I have used the latest Unrevoked to root all of the Evo's that I have rooted and have never had any problems with backups, restores and flashing Rom's.

and i got titanium back up for my apps but not sure how to use it i got idea of hot to use it and how can tell if my nand is unlocked or not

power off your phone then go into bootloader using power+vol. down..if you see s-off at the top the youre unlocked

If you are s-off, but still having problems with some root apps, you need to install busybox. You can do this from the "problems?" button in the bottom right of the overview screen in Titanium Backup. Then choose "get busybox".

Questions about rooting an EVO

Let me first say I'm a noob to this whole rooting thing and I would like to get some more info on. I tried searching the forums for the answers, but I failed to find what I was looking for.
1) What is this nand people are talking about? RUU? ROM (what's the difference between sense and no sense)?
2) How do I backup my apps, etc before trying to root?
3) Which guide do I use? My Evo came with 2.1, but I did the stock update to Froyo.- I don't wanna end up with a 500 paperweight.
4) If I need to bring my phone in for service how do I return it to stock?
5) I know you can turn your phone into a free wifi hotspot after rooting, what are some other advantages to rooting?
Any help would be greatly appreciated.

ok now let me remind you im not far ahead of you so let me tell you i would wait for a few more posts before taking what i have to say to heart, but i cant leave someone i may be able to help (even a little in need)....
1. the phrase "NAND" refers to the term nandroid backup, which is when you create a backup file. like a system restore point for windows, so when u start doing some different customizations or just try flashing some different roms assuming something goes wrong you will always be just one click away from doing a restore back to a fully functioning rom that you backedup previously. i believe the 2 main programs associated with this is amon_ra and clockwork.....
2. as far as backing up apps i just save the .apks on my pc and reinstall them once i reflash a new rom, but from what im reading you can use a program like titatnium backup, app brain...etc. but then again as far as personal experience goes...none here just what ive gathered from reading.
3. http://forum.xda-developers.com/showthread.php?t=765496
(personally ive rooted with this method and it was very simple just read through the steps before starting and follow them accordingly, dont be discouraged general computer knowledge is needed though) or atleast the ability to move about the computer)
4. returning your phone from the method discribed below is simple as it seems...but again have not done personally only from what ive read: you are rooted (assuming you've used the thread above) with unrevoked3 meaning you have s-off(in laymen terms: the position of the bootloader {ON or OFF} which checks images being flashed to make sure they are signed with the htc security signature),,,you just need to download the unrevoked s-ON file and use that to return the phones security settings and re-download an RUU(RomUpdateUtility) thats official from the htc site and ull be back to unrooted good old-fashion stock evo.
5. and as far as the wifi tethering goes just go to the market place and download a wifi tethering .apk, once rooted of course ....and run it from your evo to connect to your pc wirelessly
*this should help*
http://handheld.softpedia.com/progDownload/Wifi-tether-download-76020.html
and as far as why root, well because when you buy a phone i assume you wanted it to be YOUR phone and with rooting its all about flashing opensource/custom roms to your phone and other things such as kernels to customize the phone to your liking and you cant flash unsigned data to your phone without having su permission, meaning you need ROOT access....
-now again let me disclaimer myself i am also very very new to the whole android community and may be spewing lots of wrong info and am probably quite confused my self but i figure id risk making a fool of my self to help u in the off chance that what im saying makes any sense at all....but yea

If I can root a phone trippin on 28 triple cs you can do it

Boss dextromethorphan.....is no fun, and I dunt suggest rooting ur phone or opperating heavy machinery under the influence of triple c's....

[Q] Any way to re-install OTA Froyo ?

I see I'm not going to get any help with my bluetooth issues, and since the problem only started AFTER Sprint pushed 2.2 to my EVO, I can deduce something got f'd up during the flash.
HTC has washed their hands of the problem because apparently, I'm special and am the only one complaining.
So my question is, can I re-install 2.2, and if so, how?
I thought about rooting, but I'm happy with the phone and doubt I'd use many of the benefits other than WiFi tethering.
Besides, it's too confusing. Nand? NAN back up? MSL? dalvik? RUU? Blah?
Not to mention root guides dated weeks b4 2.2 was even officially rooted! Try to follow one guide, and it describes a step you must do first by following another link.
Ask a noob question and you're likely to get an unrelated answer (Why would you want to do that?).
I just want to fix my fu*ing bluetooth!!!
Will this accomplish what I want, as far as re-installing 2.2 (even though I'm not rooted)?

Looks like it should-- everything except doing a NAND backup first, of course.
Although if Bluetooth performance is what you want, you really should root and install CM6 or some other ROM that actually uses a decent BT stack. It's really not that hard-- the stickied thread in the Development forum for rooting OTA 2.2 explains everything in real basic terms and works perfectly.

Many thanks.
So, I don't have to go back to 2.1 to re-install 2.2?
I'll try it this weekend. If it doesn't fix my BT problem, I'll try another ROM.
It's just, like I said. My BT worked perfect with 2.1. As far as other ROMS, maybe someday, but right now Android Market And AppBrain keep me busy.
Whoops! Forgot to ask, when they say "stock" RUU, does that include HTC Sense? I know a lot of people don't like it, but I do.

Well, now, I made the "mistake" of doing more reading, and now I'm more confused than b4.
So b4 you flash or restore a RUU (ROM?), you're supposed to do a "nand backup".
Someone suggested Amon_RA , so I went to this thread:
http://forum.xda-developers.com/showthread.php?t=705026&highlight=Amon_RA
There it says installing it will wipe all your info. But I thought this was supposed to let you back up?
Somewhere else I saw this:
Boot into recovery. Select Backup/Restore. Select Nand Backup.
How exactly? How do you boot into recovery mode? I found bootloader mode, but not reovery. I found a post where someone asked that same question, of course it wasn't answered.
The problem with forums is that everything is all over the place. People get tired of answering the same questions over and over, yet the reason most people ask the same questions is... everything is all over the place!

Forget about doing a NAND backup... you need root to restore it anyways, which you don't have, so it's pointless.
Just run the RUU. It will basically give you clean 2.2 image.

I am not worthy.

Do what Sohr said you will lose everything but you will have a clean image. When it comes to recovery to get to it you must first be rooted and have a custom recovery either Amon Ra( the link you left earlier) or Clockwork Mod recovery. To get into it you could use a free app from the market called quick boot that would bott you into recovery without using the bootloader...
It all seems complicated for the first week then it becomes natural on how to do it all. If you need help with anything PM me and maybe I can help you.

Thanks. Well, I did the deed yesterday. I will take anywhere from a few minutes to a couple of days to see if my problem is fixed.
Thanks for the help. I will probably try another ROM if this didn't work. At least now I have a sense of how to do it.
Well, it took minutes. Crap. Same problem (bluetooth audio cuts in and out on my end, but not on the other persons end).
HTC told me to go to hell. I wonder if Sprint has any units in yet. I con't believe I'm the only one with this issue!

HTC Evo, want to do a froyo 2.2 stock

Hello all I just received my Evo yesterday. I managed to Root the phone using Unrevoked 3.21. But, now I just want to wipe everything and build my phone from the ground up. I wanna do the latest android so froyo 2.2 and on stock HTC Sense. Can anybody link me to a guide that will lead me to the right direction? Thanks.

You got lots and lots of reading to do. There is no specific guide, you need to learn what ROMs are what.
Good luck building your phone from the ground up and then adding in Sense.
Why did you root if you didn't have a reason to do it? You were at 2.2 and HTC sense when you bought the phone.

First things first....
1) Have you made yourself familiar with recovery mode yet and what it can do?
2) Have you done a nandroid backup yet? This should of been the first thing to do after rooting.
If you have not done this and need help just post back so u can be directed to the right walkthrough.
If you have done this and want to use your phone with the latest software and root capabilities, then I would suggest downloading the latest HTC 3.30 from here: http://forum.xda-developers.com/showthread.php?t=819838 It has not been officially released yet but seems to be very stable and contains some official fixes. I have flashed it myself and seems to be working fine. Make sure you do a full wipe and backup before flashing. This should put your phone to stock w/ root capabilities and let you build on the latest software from the ground up.
**By the way...if you are planning to use themes then download the "deOdexed" version, otherwise, get the "Odexed".
Hope this helps.

All I did was root my phone and downloaded Titanium Backup and got rid of some Sprint apps. That's about it... but no, I am not really familiar with recovery mode and nandroid back up. So, all the help I can get is always welcome. Thanks.
Also, when I do a complete wipe and reinstall the stock rom, the Sprint apps will also be included?

If it is the stock rom then unless whoever posted it took these out, then they should be on there. Can't remember for sure, but I believe the stock 3.30 will take you to exactly like stock except rooted and with new software version.
Couple things you should do first....
1) Read through this post: http://forum.xda-developers.com/showthread.php?t=790427
2) Search for how to do nandroid backup and get that done first. Without it, you have nothing to recover if something does not flash properly.
3) Read, read, read.....if there is something you don't understand search these forums or the internet. If you can't find the answer then post something.
**If you are rooted do not take the OTA updates. It could really screw things up. Check in these forums first because something will be posted about it.

[Q] Need help rooting evo. noob questions ><

Sorry about the double post. i first posted this in the Q&A.....
So i am a iphone user moved to android. im trying to root my phone and just cannot seem to get it running.
I have download simple root .1
I click setp1, it does its thing, goes to the skating guys and i do what it says.
Next i do step 2, same thing. skating guys, i do what it says.
now when i click step 3 the phone reboots and on my phone i get a phone with a read ! and triangle over it. nothing happens after that......
reboot the phone nothing seems changed.... what am i doing wrong?
anyone have a more complete "walk through"?
Also, i am a little confused. some people are saying to put "roms" onto the phone. are the roms like the OS? how do i wipe the phone and put a new rom on?
i am looking to get 2.3 onto my phone and get free wifi hotspot tethering.
i am running windows 7 ult. 64.
also, any links where i can get apps that only rooted phones can get?
any help would be great. sorry for the noob questions

Root using Unrevoked. It is the easiest method by far. Once you have root and s-off, you can worry about flashing custom roms. I'm not sure what you mean by "simple root .1" so you may want to post a link to what you tried so we know where you stand.
Also, it'd be easier to help if you provide your phone info as far as which hardware version, what software is on it now, which hboot, etc. If this is all new to you, then read some more and get a better understanding of this before you mess up your phone.
Can you boot your phone normally or is it stuck somewhere?

Simple root it outdated, you can check out the following thread for info on how to root.
