Unrevoked 3 NAND unlock? - EVO 4G Q&A, Help & Troubleshooting

Hello, I am new to this but successfully used unrevoked 3.1 on my evo. From there I installed two roms under clockwork recovery from zip files on my sd card, one worked, the other did not. What I am confused about is that they say unrevoked does not allow NAND write to /system, but yet I was able to flash a custom rom? i thought i had to be nand unlocked to flash a custom rom? Thanks !

should I post this to a different part of the forum or...

If you have a "Question" to which you would like an "Answer" then the "Q&A" section will suffice.
Regarding your question, my answer is to use the "Search" button or read the threads first. - You won't believe how much information I've learned just by reading through a thread with a couple hundreds pages of "good" feedback on root, roms, and what type of root methods to stay away from.

My question wasnt really a general question and is about development so I thought it would be appropriate here. I have read this forum since 07 and this was the only question I wasn't able to find anywhere. No one has spelled out exactly why some roms need nand unlock and others don't as far as I have seen.

I've noticed this too. I'm using baked snack with no issues but can't run damage control.

Certain ROMs will require you to have NAND unlocked others not, this isnt a development question though its a general question about how to root the phone.

What is the difference though ? As in why if one rom can work nand locked why would another not be able to work? I'm trying to understand whats happening here.

more importantly, does anyone know how to nand unlock? Simple root doesn't work on my system after unrevoked..

If i was you i would go back to stock RUU and try Toast root method 1 and 2 for the full root, or if you got the 1.47.651.1 the the SimpleRoot.
And i believe the difference between ROM that need or does not need Nand unlock is that some roms writes in nand and other doesn't.

I've been trying to figure this out as well as I have 1.47.651.1, rooted with unrevoked 3.1, and have been trying to unlock nand with no luck. I'm on a mac so simpleroot won't work for me (even tried it on my work PC, but something is messed up with the /net framework, installed 4, but simpleroot says it can't find it), and when I try toast's method I get "permission denied" errors when trying to use the adb system. So I'm kinda stuck on what to do right now....
Scratch that, found my problem.. Forgot to startup superuser access...

I also rooted with unrevoked 3 and want to get the nand unlocked.
Did you get it to work on your Mac or the PC? I'll continue to search around in the meantime and see what the best method is... I'd rather do it on my Mac, but I can find a PC if I must.
thanks.

Scroll down to install instructions, download the forever zip and then flash in recovery, and you'll be all set.

Unrevoked 3 "other" benefits?

i am very grateful for the fact that my phone is finally rooted again, and would like to say thank you to the unrevoled team.
i was wondering what were the other benefits that they claimed came with the unrevoked 3, i dont have them and how do i get them?
*This was posted from my Evo 4G*
I came from the palm pre and have been reading here in the forums about rooting. Not a computer tech so I thought I would try unrevoked. It seems to be the easiest but I was wondering as well with the OP what are all the pros and cons of this rooting method. Thanks
I posted this in another thread, but i don't think unrevoked is a true unlock. I know Toast said that at v2 & i am guessing it is the same thing with v3. From what i've read it only unlocks the NAND "when needed" ( which i think is via Recovery ) so i don't believe you can do things like remove stock apps via unrevoked.
If i am wrong, please let me know & i'll correct my information.
EDIT: As marclile posted, if the NAND is only unlocked in Recovery, then stock apps can be removed, it just has to be done while in Recovery via ADB.

i don't know 100% but if it does only unlock NAND when you are in recovery, then you could still remove apps that you didn't want. you would just have to do it via an ADB shell while the phone is in recovery.
Wasn't thinking when i posted, thanks. I corrected my post above.
Im a noob so forgive me... what is nand, and what is abd?

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.
http://theunlockr.com/2010/07/20/how-to-unlock-nand-on-the-htc-evo-4g/
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".

Who should I get my root from?

I'm thinkig Unrevoked team. Should I do Unrevoked3 or forever?
Please any ideas? Custom recoveries or ROMs?

Hahaha research
Unreevoked 3 and forever are two totally different things. Foreverr is now obsolete with the release of 3.2.1. I wouldn't use unrevoked because then you have no idea what root is and how to use it. That's my two cents.
I will be using unrevoked 321 tomorrow to root my new evo. My first evo I rooted using simple root.
I disagree with dkdude36. I did it the hard way when the g1 dream first got rooted. The process is academically enlightening but a waste of time really.
Go for the easy root (unrevoked) unless u have a lot of time to spend learning.
I disagree with jdbiggles...
If you understand how to use a terminal (ADB) and know how to type without error, "the long way" doesn't take more than an hour to obtain root access to your evo!
My personal opinion is to get root with ADB. The things you learn will help you in the future.
Root with unrevoked, as it gives you one step nand unlock and everything. However, if you are not willing to learn ADB and the such, do not root your phone at all.
If this is the first time you have ever rooted an android or HTC device I would recommend doing the "long way", not because it is some stupid right of passage, or that I think you are a dumb n00b if you don't, but because I think that it will help you a lot in the future if you ever run into problems. You don't want to be learning about all this stuff with a bricked phone.
My first experience with rooting / custom roms / adb was with a G1, and then with a Nexus one. This time around, I simply used unrevoked, but that is because I already understand how the process works, and just want to get it done. It is kinda like math class, they make you write it out with pencil and paper, and then only way later can you use a calculator, because if you never did it long form, you would have no idea if the calculator was right or wrong, or any clue of where you made a wrong calculation.
If you run into any problems now or in the future with an android device, you will actually be able to at least sort/solve the simple problems, before needing to post here and wait for an answer, and hope someone posts step by step instructions.
Below are questions I posed in another thread. The root question is apropos to this thread. Can someone please provide me with some direction? I don't mind doing the "manual" way.
Thanks.

1) Is there now a way to use pattern lock only? The Evo still shows the drag down HTC screen lock even when pattern lock is enabled. I have searched all over, have yet to find a solution.
I don't want to run a custom ROM. Will a root give me some ability to disable the drag-down lock?
I also have a Nexus 1. When I enabled the pattern, the regular screen lock is turned off. That is the behavior I'm looking for with the Evo.
2) Root: I want to root to enable all apps to SD, copy files, enable "reboot", etc. I do not care to run a custom ROM. I don't mind having to re-root after an update. I do not want to wipe my phone. I WANT to maintain the ability to receive future OTA updates.
On the N1 platform, there is an easy root method to allow for this. I get Superuser, can run root apps, but still receive OTA and no custom ROM. I'm looking for the same here.
For the Evo, which method whould support this?
I would very much appreciate any help.
Cheers.
Edit: I know what a generic NAND memory is. In this case, why is NAND protection and why does it need to be disabled? What is "S-On/S-Off". I looked through the guides/FAQ, but haven't been able to find anything. Thanks again.

I have rooted my G1 before the long way. I understand how it works, just wanted to see if there were better teams to get it from? But I think this clear, unrevoked forever.3. 2.1 doesn't work anymore?

[Q] Newb needs help/explanation about how to root my MT3GS 2.2.1

ok, ok put the stones down....DOWN. yes Im a newb, but im not an idiot. I have spent the last hour tonight (as well as searching a few times over the last 2 weeks) searching, not just this site, for a way to Root my MT3GS. and apparently its currently impossible.
Yes I am aware of these threads:
http://forum.xda-developers.com/showthread.php?t=1181214
http://forum.xda-developers.com/showthread.php?t=1108316
and http://forum.xda-developers.com/showthread.php?t=1189485
however none of these fully explains anything and after reading all the replies in these threads it seems that theres conflicting comments, which are confusing me to no end. so Basically I have 3 questions:
Can I root my MT3GS what is currently running the OTA push of 2.2.1?
IS there a way to get S-Off working on it?
Can I Put any new Rom(could very well be using hte wrong word, if so it should be easy to understand what i mean) on the phone so that I can remove all unwanted stock apps, install any marketplace app I had before, and (drum roll please) get NETFLIX to work on my phone?
thank you in advance to anyone who can help me. but please, please please don't just refer me to another thread, because odds are A) I have read it and it didn't explain it well enough for me to understand and feel comfortable doing it, or B) it didn't provide the needed programs or only discussed part of my question and didn't seem to fit up with other threads which covered the other areas.
in short:
1- yes, you can root it. i've done it 3 times on my phone
2- as far as now, no, unless the new method posted today actually reverts the hboot
3- yes, although there might still be some apps that are on the rom that you do not want.
hey txdeathray, thanks for your reply. I found eckres original post on a different site that was much more elaborate, but from what i read still doesnt specify the S-off problem. last post: forum.cyanogenmod.com/topic/28205-stuck-on-step-8-rooting/
SO basically, if I CANT get s-off working, then even if I put cm7 or whatever other version i find, as soon as I reboot my phone, it will undo everything I did and ill be stuck with 2.2.1 again.
Have you tried the unlockr.com way to do it? Their page has a vid following you thru the process.. id post the link but im mobile at the moment

No. You don't need S-OFF to keep a new ROM. And you won't lose root with S-ON.
To my understanding, you only need S-OFF if you want to be able to manage some things without having to reboot your phone into recovery, or to get to some system files you otherwise can't with S-ON.
I have not seen the need for S-OFF for my personal use of my phone.

[Q] Rooted, didn't do nandroid backup -- any chance of recovering data?

My fiancee's EVO 4g was in desperate need of replacing, so we went and got new phones. She had been playing this damned Smurf Village game for about a year and a half, and I thought I'd pull a white knight -- root the phone, back it up on Titanium, transfer the backup to the new phone, root that, restore. She insists she's okay starting over, but I thought it'd be a nice gesture. Rooting the new phone (LG Optimus G) was a piece of cake. The EVO 4g took me some time to get it to work ...
In my poor attempts at multitasking, I didn't do a nandroid backup and completely overlooked where it said it would restore to factory settings.
Is all lost? I did a search on it while it was plugged into the PC as an external drive and found a bunch of (edit: Smurf-related) files, so I feel like the data might still be there.
If not, it's all good. I learned from my mistake (I mean, c'mon, big_onion, every damn set of instructions says "make a nandroid backup") but if there's any way to get it back it might make her day.
Data restoration aside, after flashing Superuser, I still can't get TitaniumBackup to obtain superuser privileges. Any ideas what I might've done wrong? The method I used was to unlock the bootloader via HTC site, then flashboot recovery, then flash superuser. The app is there, but it doesn't seem to issue SU rights to TitaniumBackup.
Best way to gain root is to flash any custom rom here on xda. Unless it is a completely stock rom it is rooted and works without any issues. I rooted my second og evo a few days ago and had the same issue with the stock rom. After flashing a custom rom I had full root access.
Now as far as data goes most apps store that on the sdcard. I suggest installing the game on the new phone then power off and insert your old sdcard into the new phone. Hopefully it will use the old data and return your wife's game to her last state and make you look like a champ.

Uhm...
You don't root android by flashing a rooted custom rom on a non root phone.
Rooting a phone must be done via a PC there is no other way.
Some stock roms ARE root.
The reason you had problems is because you were root and tried to install a non-root stock rom, if you would have installed a rooted stock rom you would of had no problems.
smh
Umm root is done by rom. Unlocking bootloader is the part done by pc.
You can be unlocked without root but can not root until you are unlocked. Rooting is the granting of admin rights to the user's apps.
I did not have an issue because I installed a non rooted rom. The rom was already on the phone which is the same spot the op is in. He is unlocked but not rooted. The htcdev unlock does not grant root rights to the current stock rom. Also the flashable zip did not grant the rom root rights.

You don't go from not being rooted to being rooted by flashing a custom rom on the phone from the recovery menu, unless you accidentally flashed a non-root rom while you were already root.
Unlocking bootloader is the part done by pc.

They're both done via PC at the same time with the same program (Unrevoked3 is only temporary nand)
Unrevoked Forever unlocks the bootloader permanently via recovery with an .img
http://wiki.rootzwiki.com/UnrEVOked
Wow man this will be my last response here about this but I want to say a couple quick things. First did you even read the link you posted? Yes with unrevoked you can gain nand unlock and root at the same time but if you also read it says this.
Does unrevokedĀ³ give me root?
Yes. It previously did not; as of version 3.0, it does.
So root and nand unlock are not the same and is not always done at the same time. It is possible to be nand unlocked and not have root. Which is the case when you use htcdev unlock. Do your homework before you go making statements please.
I am not here trying to run anyone down and start fights but I am here to spread knowledge and help out others with problems. If you give someone bad information it will cause problems down the line later. Most people will assume you know what you are talking about when you make a post even if the information is not correct. So please take the time and make sure your information is correct before you post it.
So take a look at links I have posted and see what root is, how it is used, and see the difference.
This is a general overview of the root permission (depending on os it is called many different things)
http://en.wikipedia.org/wiki/Superuser
This is what it means with the android

OP has the information he needs.
He already is rooted and needs permanent unlock which is what Unrevoked Forever does, which is linked in the link I posted.

I guess he thinks Unrevoked Forever is bad information and harmful to Evos.
Backedup
If you backed up the game, you can always download titanium backup and restore. Make sure you didn't delete the files from sd-card (they should be there). Sorry if this was already answered or i'm wrong. :fingers-crossed:
edit: if its a stock rom and you backup every app with titanium back up you could.
jlmancuso is having a hard week. i would give him a break. as far as i can tell he's genuinely trying to be helpful and is catching crap from all sides these days. eventually he will slow down and not accidentally provoke people (or take things personally). but he seems like valuable asset to the community overall so i'm rooting for him. OP good luck with your issue.
It's already unlocked, via the instructions from the HTC dev site. I didn't use Unrevoked -- I tried, and got a message about something being too new of a version. I'll dig around more, but I before I spent too much time I wanted to make sure I could restore the data on the stupid Smurf game for her.
I did NOT do a Titanium Backup of anything on there before I started. The LG Optimus G doesn't have an SD card, so I can't just swap SD cards. I can copy files from the EVO to the PC then to the LGOG. I think I might install Smurfs on the new phone, root it, then just try and copy the Smurf files from the EVO over to the Optimus G and see if overwriting the data files would restore her game.
Will report back on whether or not it works, or if I can't get superuser working.
And chill out, friends. I appreciate all sorts of info, even if it's not what I'm looking for. Y'all rock.
I am not taking it personally and dont think unrevoked is harmful. I am not going to argue with anyone about the facts. I posted the articles al5uwtqind if anyone wants to read them and learn more than cool. The information is for the benefit of everyone. Call troll or a$$ or whatever. I am here to help like most everyone.
Knowledge is power so empower someone else today.

I think he meant "Htcdev site" then "fastboot flash recovery", but it seems like Big_Onion did everything right as far as rooting the phone, but there can be other reasons why Titanium is not working properly. It could be Titanium data needs to be wiped or it could be an issue with busybox. He never said he was not rooted, he only said that superuser was not giving Titanium root permissions, which has happened to me also. I wish he would have ran the root checker app too, to verify did he really have root or not. Then it would be easier to tell which path to take.
And also, why are we arguing over unrevoked and unrevoked-forever? Those don't work on the newer stock roms, because they were patched in 2011 by the first Gingerbread update on. Since big_onion used the Htcdev site, he is likely on Gingerbread. They, unrevoked3 and forever, would only work if he downgraded the radios to the ones which came with either Eclair or Froyo, the two previous operating systems. Titanium backup only needs an unlocked bootloader from the Htcdev site, and superuser permissions from the superuser app to work. Anything else is just extra, at least on Gingerbread.
