[QUESTION] Root FRF91 without touching boot loader - Nexus One Q&A, Help & Troubleshooting

I know the update was a security fix but am looking for a method to root while remaining as completely stock as humanly possible. I've never rooted before and am still completely stock now.
Best case scenario would be to gain root while leaving everything stock, boot loader, recovery, etc.. maybe even try one of them nice roms for the first time (i hear cyrogen is the best and yes I probably misspelled that)
Thanks

Same question

There's a couple of tutorials about this in another thread.
If I were you i'd follow one of them and also install a custom recovery. Then play around all you like with rooted roms, stock, custom or otherwise. Once you have a custom recovery you can flash anything. The only down side is that you won't be able to install any OTA roms. But to be honest they appear on XDA in a format you can use on custom recovery way way before you ever receive an OTA notification anyway.
Then if you're sure you only want a stock but rooted rom, then install that and then finally flash the stock recovery back.
However if you're sure you don't want a custom recovery and only want root, you can follow the first half of the same tutorials.
I myself have an unlocked bootloader, but if I didnt, I would root, install a custom recovery and never look back. If anything ever happened to my device i'd just flash the stock recovery and stock firmware and send it back.

Ok, thanks!

That's good information but I'm unsure if I want to unlock at the moment. Thanks but I'll wait a little longer to see if a solution comes out that this my needs.

No, thats the point. You dont need to unlock to root OR put a custom recovery anymore. See here for example:
http://forum.xda-developers.com/showthread.php?t=710842
So you can root, put on a custom recovery, try different roms and then go back to stock, rooted or not, without unlocking the bootloader at all.

I see what your getting at, that's what I was looking for but wasn't sure it was working for FRF91 the last few posts in that thread indicated an unlocked boot loader last time I looked.
I thought the update was to fix the security hole that allowed that

I have read a lot of comments on the guide of how root the nexus without unlocking the bootloader and searched in other places but couldn't find an answer to my question...
I've got at&t version nexus unrooted and I updated it to FRF91 OTA.
can I use this guide to root it without unlocking the bootloader?
If I can, how do I do it? some people wrote that I need to use Passimg.zip
but I think It's for T-mo version only because at&t's version doesn't have the erf79 (I hope I wrote it right).
anyway I'm really confused. can someone please explain?
thanks

New Nexus One ques about rooting

I am receiving my new N1 Fri. Have been reading about rooting and all, does a new phone come with all the settings to the factory resets? Are there differences between my unlocked AT&T phone and others? If I choose to upgrade to new ROM's are my steps different? Been trying to figure it all out but unsure. Thanks
yes it comes with factory settings if its brand new.
upgrading to new roms won't be any different if you're on AT&T.

Makes sense. If I do decide to install a rom I would only have to load the file onto the sd card and install? Are the advantages of the rom's better performance or features?Been spending a lot of time trying to get educated but too many ques.

all nexus ones are unlocked lol. and yes you do not need root for froyo and there are ways to downgrade to an official 2.1. an unlocked bootloader allows you to run unofficial roms cooked up by people and lets you flash anything you want.

you don't need root for froyo but you need the correct zip to flash.
theres one for people with root access and the other is signed by google.
you bought an unlocked phone but your bootloader is still locked.
just make sure you follow the 2 prerequisites first, then follow the instructions on that post. you'll be good to go.

So I would have to root to make my phone able to run Froyo? Correcting the zip to flash is making it able to run flash? I know it is elementary but not sinking in.

nope... I must be confusing you.
- you do not have root access after flashing froyo
- no you don't need root to flash it
- follow the steps in the thread and you will be fine
You do not have to root to run froyo. There are two flavors of Froyo floating around the net. They are the same OS version, but each can be used on a different setup.
One is a .zip signed by Google that can be flashed on an untouched/stock Nexus One, i.e. a locked bootloader. It's just a simple option selection in the bootloader to enter recovery mode. Recovery is where the updates are flashed.
The other version of Froyo that is out there is one that has root enabled, which is not signed by Google, and can only be flashed using a bootloader that is unlocked. Remember everything is flashed in recovery mode. By unlocking the bootloader you are able to replace the default recovery (which only allows the installation of signed files) with a custom one. The custom recovery allows you to flash unsigned files, many of which have root access.
In short, unlocking a bootloader does not give you root. It simply provides a mechanism by which you can flash an update that has root.
The signed file is only available for the T-Mobile 3G frequency phone thus far. It can still be flashed on an ATT one, but additional steps are required.

How do you flash a recovery image to gain root if root is a requirement!

Been all over the forums and in order to flash Amans recovery, Modaco requires a rooted device and superboot. Well, we know superboot isn't available for FRF91 yet and to flash requires root.
How the heck does anybody flash a recovery image without root?
The goal here is to get root and and this point don't really care if the bootloader is locked or unlocked. Just need root access to run certain apps.
Was planning to boot into recovery, then run the passion update for root access, but this is a catch 22.
If you do a search... yadda yadda....
You must downgrade to frf83/5? i forget the exact number. There's at least 3 different posts on general...
fark it, start here, and then SEARCH.
http://forum.xda-developers.com/showthread.php?t=717870
I was in the same boat as you. I flashed the RA Recovery and although it said it was flashed successfully, when I booted into recovery, i saw the stock recovery. Was on FRF91. So took a gamble and flashed the latest superboot from modoco. Cant remember if it was FRF83 or FRF85B and then reflashed RA recovery. It worked
Once in RA recovery I wiped and flashed a cooked ROM.
Already tried EPE76 and was screwed lol. Ran the universal update back to FRF91. Looks like I'm going to have to downgrade again unless there's another solution. Would like to know how to flash a recovery rom without root.

Well I was on FRF83 then recieved the FRF91 OTA from Google.
As there was no FRF91 superboot on Modaco i flashed the FRF83 version.
I also kept the universal update in my SD card just in case but it went smooth for me.
This bites. There's no clear cut guide how to root. Just bits and pieces of information and a complex labyrinth of instructions. Most of the info is outdated and requires a downgrade, then upgrade, then recovery. The recovery requires root and the whole goal is root lmao. It's no wonder there are almost daily posts of guys trying to root and/or unlock bootloaders but nobody knows how to explain the procedure. The stickies have dead links, and everyone says "hit the search button" and not one person has created a sticky for rooting instructions on the FRF91. I actually downgraded to EPE76 and got stuck due to the inability to upgrade to anything except back to FRF91 AT&T stock.
It would be nice is someone actually took a few minutes to explain a working procedure how to downgrade, upgrade, and use recovery to gain root. Really don't care about the bootloader. Somebody will get rich with paypal donations and I'll be the first to donate.

its up to date. if you unlocked your bootloader, the outdated root guides are fine to use even now. you need to ensure you flash a custom rom so the recovery isnt replaced on reboot

[Q] Froyo 2.2.1 - Rooted Version?

Hi All,
Was just looking into the prospect of rooting and I came across a post that basically responded to a guy asking whether subsequent OTA/Official updates would revert the root. the response was:
this might well happen. To be sure that this won't happen, don't update, or wait for a rooted version of the update to be released
Click to expand...
Click to collapse
It's the bit in bold that's got me wondering. I have my Nexus running stock ROM but rooted (with locked bootloader). I have the problem with the WiFi which 2.2.1 claims to fix.....and I just wasting time thinking that this update might get released as a rooted version so I can just install and not worry about losing root?
Any help gratefully received.
Cheers
1. Already released as a rooted version (check the ROM section)
2. Really easy to root with rageagainsthtecage ...
Right I can ask you the question then......with the rageagainstthecage root method, is there anyway to install the update without flashing a new ROM...I'm ok with stock.
If you're rooted - install custom recovery and install pre-rooted ROM.
Or try to apply the stock update through stock recovery, if you have it.

Just install the OTA - it will unroot you.
then root with "rage"
check out modaco, he's got frg83 completely stock with root. just flash using custom recovery. I didnt do a wipe so everything stayed the same just updated to 2.2.1 and yes it seems the wifi issue was fixed.
Just get the stock rooted from geo411m's rom!
http://forum.xda-developers.com/forumdisplay.php?f=559
The links here will also do it in 2 steps from custom recovery:
http://ip208-100-42-21.static.xda-developers.com/showpost.php?p=8419658&postcount=194
The geo411m link is a deodexed ROM and the one in the link above is not deodexed. Either way you get the fixes of the newer version.
Going forward, think of it this way with future updates:
If you apply the OTA, intending to lose root and then re-root, you always run the risk that all avenues of rooting (other than unlocking the bootloader) have been closed by the new ROM.
If you apply an update repacked for custom recovery, you don't have to worry whether the root exploit you used last time will still be valid.

Ahh found a flaw in my plan.....it seems that verification fails on my Vodafone Nexus One (UK). I'm guessing there isn't an upgrade path from Vodafone's Froyo update to this yet. Suppose I'll have to wait for Voda's 2.2.1

[Q] Install AT&T OTA Update with unlocked bootloader?

So I'm wanting to install the OTA ICS update but it fails and I get the little red exclamation point when I try.. I am assuming this is because my bootloader is unlocked? I've been trying to find a way to install it but the only one I found was one requiring S-OFF which I don't have..
So basically my question is can I install ICS on my rooted unlocked bootloader?
If absolutely necessary I can always lock it, install, then re unlock it but that's such a pain.. AT&T gets on my nerves sometimes..
I am almost positive that you have to do the re-lock process unless somehow they found another way. You should probably read around next time. Most likely, someone has already asked your question.
Sent from my HTC PH39100 using XDA
I've read quite a few threads but haven't been able to find anything.. and like I said, I did find one but it requires S-OFF and the juniper thing, or whatever to lazy to look up the name right now lol, is not released yet.. and I haven't been able to find another way to get S-OFF..
If you want ics that bad you have to do it like every one else here...there is no reason to whine cause your to lazy to relock the bootloader ..it take all of about three mins for me to relock mine ... and about 20 min to do the whole process...you don't need s off to get ics if your using the vivid or velocity. there's no place for lazy people here so please just do it like ever one else or do with out
I'm fully aware you don't NEED S-OFF to get ICS its the only way I have found to do it with an unlocked bootloader if you even bothered to read my post. And if your going to be rude and unhelpful stay out of my thread, people like you are why forums loose members. I simply asked a question I never said I was lazy and wouldn't do it I was simply looking for an easier alternative.
The S-OFF is obviously a mistake, because if it was S-OFF then you wouldn't have to do fastboot oem lock.
Yes, you have to relock the bootloader. Make sure you kept your unlock_code.bin or else you might not be able to unlock the bootloader again.
To be extra safe you should flash stock recovery before you do anything.
Quick question going along with this, it may be stupid, I just wanted to make sure before I try anything: I'm currently on RumRaider and I want to switch to ICS. If I were to revert to stock and relock and then do the OTA update to ICS from AT&T, can I still get root with the same zergrush application or whatever that I used before?
