Is it really possible to flash a custom ROM on a nexus one with only root and without unlocking the boot loader? I was under the impression that it is impossible but the nexus one wiki states you can either unlock and root or root without unlocking and flash a custom ROM. Would this work with CM7? Thanks and sorry for being a noob but I couldn't find a clear answer to this.
Yes you can, I'm on CM7.
Thanks so much, also does anyone know if there are any special steps involved getting there if you have a nexus one with a slcd panel. Steps for getting back to stock would also be awesome! Thanks!
EDIT: Just to verify, custom recoveries are overwritten by the passimg method of getting to stock correct?
Root and passimg are the same for slcd and amoled panel there are no special steps. Passimg will not revert you back to stock recovery but it will return the stock ROM which upon boot reverts the recovery back to stock.
Thanks for all the answers. I've put together a little guide for what to download etc etc... I think I'll bundle everything and upload it with instructions at some point. Please do tell me if there is a complete guide to flash a custom rom without unlocking that is not as confusing as the wiki for noobs. Also I believe my guide would alleviate some slcd bricking...
Look for a thread sometime in the coming days...

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

they should work in the same way as it did for FRF83 or FRF85B.. you could always try without harm

is a guide of how to downgrade from FRF91 to FRF85 in an unrooted nexus.
that way you can use this tut and root it w/o touchnig the bootloader
EPE76 to frf85B
Hi,
I am back from frf91 ota to EPE76 by applaing passimg.zip. My question is how can I move to frf85B ? I've tried to download universal frf85B, change name to update.zip and go to recovery, but I only see exclemation mark. Please advise. Thank you.
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.

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.

just read the sticky for rooting without unlocking bootloader in the android dev section
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
Hi all,
Apologies if this has been answered elsewhere, I checked the FAQ and a forum search and found references that this could be done but no real instructions.
My friend has a Vodafone UK Nexus One and as you probably know when Google release an OTA it's about a billion years (or at least it seems) before it's rolled out to him as it is my understanding that Vodafone have their own special build. Therefore I'm wondering if there's any way of flashing a stock ROM onto his Nexus One (probably after unlocking the bootloader) so he can get future OTA upgrades when everyone else does?
Any pointers gratefully accepted
- echo
You can unlock the bootloader if you want, or not.
If you unlock the bootloader, download the FRG83 system image from http://developer.htc.com and use fastboot to flash over the system and boot images
If you don't want to unlock it, then use SuperOneClick to gain root, install ROM Manager and use that to flash a custom recovery and boot into it. From there you can flash the stock but with root .zip from here: http://forum.xda-developers.com/showthread.php?t=927935
Thanks Rusty, that seems to answer it! Now I've just got to convince my friend that flashing like this isn't actually that difficult and dangerous
As you're not touching the radio, it's not dangerous at all. Worst case scenario is you lose your data, so take a backup first to be safe.
I have an N1 that I unlocked and rooted and was running CM7 RC1 when I decided to try the stock Gingerbread. This switch went perfectly, but now I don't think I want to stay on the stock GB but I can't seem to get ROM Manager to boot into recovery to allow me to flash another ROM. Do I have to do something differently now? BTW, I do not have root on the 'new' GB.
Thanks.
Unless you flashed a pre-rooted version of Gingerbread, you will have lost root and your custom recovery...
If this is the case, you have two options:
1 - Flash a custom recovery through an unlocked bootloader.
2 - passimg back to an older version of Android and root again...

This is your problem. ROM Manager installs a custom recovery, but only when your phone is rooted. You need to re-root GB.
Can I ask them how people flash custom recoveries without having root? I see threads all over the place that say that you don't have to root your phone to run these custom ROM's.

You have to root, but you don't have to unlock your bootloader.
You have to do one of the things:
1) Root.
2) Unlock the bootloader.
Rooting allows you to bypass security mechanisms from within the OS, and flash the custom recovery from there.
Unlocking the bootloader turns off the security mechanisms, and you can flash whatever you want directly from bootloader.
Both achieve the same thing, but in different ways.
Root privileges in OS are lost upon official upgrades.
Unlocked bootloader is never lost.
Unlocked bootloader allows for an easy way to gain root in the first place, regardless of the ROM.
How does an unlocked bootloader allow me to flash whatever ROM I want? ROM Manager won't run without root? Am I missing something? I've read the wiki's and threads about rooting an N1 and they all just seem to stop at unlocking the bootloader, well, my bootloader is unlocked but I can't get it to boot into CWM so that I can select another ROM. Is there another way to do this?
ROM Manager is only one, and not the most successful nor most powerful, way to flash ROMs or recovery. ROM Manager was made for non-understanding people to make the process look and feel easier. The most powerful way is directly from bootloader - which needs to be unlocked to allow it.
If you read all the threads, you'll see that unlocking the bootloader is just a first step - you can look carefully at "installing custom ROM" guide in Wiki. Or, for example, here:
http://forum.xda-developers.com/showthread.php?t=636795
Read the Wiki, look for recovery installation instructions using unlocked bootloader, execute. I suggest Amon_Ra's.
Have there been any custom roms made for this phone yet? I have my boot loader unlocked and twrp installed. Ready to play with my phone a little. Wish I knew how to make roms myself. By the way the step by step guide for unlocking boot loader and installing twrp and super su was awesome. Thanks
There is custom kernels and de bloated and rooted Roms but nothing like CyanogenMod or aokp yet ive been looking like everyday.

At the risk of sounding like a ****, what you see is what you get in the android development section of this desire 626 forum. So no, there are no custom ROMs, however you might find some debloated stock ROMs that a few people in here have spent a lot of time and effort on. hope this helps....
There are custom kernels?
Please can I get a link to custom kernels for this phone? I'm also having issues with my unlocked sprint 626s as I'm stuck on 2g will flashing a new radio solve it or any suggestions?
