Why did I lose root? Please help! - Nexus One Q&A, Help & Troubleshooting

First off I would like to thank everyone on this amazing site for all the advice, guides and tutorials.
I unlocked my nexus bootloader and flashed a couple different roms. I really like the rom manager so I've used that to download roms and then flash them using that app.
When I downloaded the stock version of 91and flashed it, the phone no longer seemed to have root or clockwork recovery but my bootloader was still unlocked. When I downloaded rom manager, it could not get super user permissions, this being useless in flashing a backup or new rom. So I used universal one click root to gain root access and then rom manager was able to flash a backup.
I know this may be a dumb question but hope someone could explain to me why I needed to re-root and why I lost clockwork recovery...?
Thanks for the help in advance.

Right theres your problem. stock roms dont have root built in you have to root them again. unless you download a prerooted stock rom. hope this helps.

Yep this seems to be your problem. If you're wanting stock with the basic add-ons then the first link in this thread is your answer: Link.

Thanks very much. That does make sense. I thought unlocked bootloader meant I was rooted regardless of rom! I'm in way over my head lol. Looking forward to learning more...thanks for the new rom link as well

The advantage of unlocking your bootloader means you can flash a custom recovery from Fastboot mode, without having to "root" the ROM. Next time this happens you can just boot into fastboot and flash clockwork from there like this:
fastboot flash recovery PATHTO\RECOVERYFILENAME.img
so say you download clockwork and save it to c:\sdk\fastboot named recovery.img from a command prompt you enter the following
cd \sdk\fastboot
fastboot flash recovery recovery.img
once it is done flashing you can do this
fastboot reboot recovery
and that should take you into clockwork where you can flash your favorite ROM (or restore a backup).

Thanks for the help. I will be sure to try that method out next time. Very helpful.

[Q] flashing custom recovery - frustrated!

Hi,
Upgraded to 2.3.3 and lost root.
Bored of mucking about with oneclick etc, I unlocked the bootloader. Easy(ish), cool!
Trying to flash amon ra with fastboot, everything goes well (appears as though it's flashed). But when I re-boot, it isn't there!
Padlock showing - so bootloader unlocked.
Nexus drivers installed, device showing with "fastboot devices".
Trying to flash amon ra 2.2.1.
Any suggestions?
Ta!
Andy
When you boot a stock rom it wipes custom recoverys and puts the stock one back.
Use the search feature on the forum.

Thanks for your reply.
I've spent (literally) all day searching the forum (I'm in the uk - so hours and hours). There's so much, and some of it contradictory.
Ok, so I can't put a rom on without a custom recovery, but I can't put a custom recovery on because the stock rom wipes it?
I don't actually want a custom rom, simply a rooted stock phone. Which I have had previously.
Cheers! (driven to booze!)

Yes, that's what I've been doing. There's a mistake in that part of the faq:
Faq states at the end "reboot recovery"
Should be "reboot-bootloader"
That works, but as soon as I then reboot into 2.3.3 - it wipes the custom recovery (which is why I'm in the q + a).
The other problem I'm having is that my phone doesn't appear rooted from within the o/s (apps that require root don't work), but the padlock is there ans the bootloader is unlocked. I can install su and busybox installer from the market, but neither work.
Back to the beer!
Andy
I can't explain all in detail while on my phone.
Do this. Grab a preroooted stock rom from the dev section and put it on SD card.
Boot into fastboot and flash the custom recovery.
Then load up that recovery without booting up the os.
Flash the rom you downloaded.
There are other ways to fix your issue but this is probably the simplest for you.

Thanks, that makes sense - and I agree with your statement above (simplest for me)!
I had (mistakenly) thought that unlocking the bootloader, then installing busybox and su from the market gave me a rooted phone.
I'll give it a go, when my wife regains her patience ;-)

Damn, you're right. The guide is missing the part of removing 2 files that the other guides have. I'll try adding that.

Guide fixed. I've uploaded and linked the file that removes the stock recovery restoring files from the stock ROM.
You can repeat the guide and include the new part - it should prevent stock recovery from being restored on reboot.
Please try and write your feedback.

[Q] How to root nexus one 2.3.6 with locked boatloder

Hi guys
Can any one tell me how to root nexus one 2.3.6 ,i have locked boatloader.
zahid
Try SuperOneClick
http://forum.xda-developers.com/showthread.php?t=803682
or unlock the bootloader, fastboot custom recovery and flash ROM of choice.
Try this

Use this. I just rooted my stock 2.3.6 nexus using this method. Takes less then a minute once everything is downloaded. Just make sure to extract all the files into the same location as the adb.exe file. Usually its in android/platform-tools.
Good luck and let us know if you have any questions.
BTW it does not unlock you bootloader either!

You're good to go. Just install a custom recovery
CWM or Amon Ra, you can install them via Rom Manger.
hi
I tried to install custom ROM but when phone reboot it stuck on "triangle android" seems first i have to unlock my boatloader.
Can you post me link..
It means that you didn't flash the file that removes stock recovery reinstaller - and stock recovery is reinstalled on stock ROM boot.
Reboot back to ROM, root again, this time when you reboot to recovery first time, flash the file. It's found in Nexus One Wiki, section "Recovery".

Its not at all necessary to unlock the bootloader. Did u install custom recovery before flashing a custom rom? I think u skipped that step.
Simple and best way for starters like us is to
1.root via super one click root
2. Install rom manager from market and wid the help of that, flash clockworkmod(cwm) recovery.
3. Install Titanium backup from market and do a backup up of ur apps.
4. Choose the correct rom of ur choice by reading the OP and the thread.
5. Download it and install it via rom manager.
6. Before that back up your current rom and wipe the system,cache,dalvik cache.
Thats it, u r good to go. :thumbup:
This is how i did n doing good
PS: Am just a newbie, so if there's any mistakes in my steps pls correct me.

[LG-H901] Stock ROM, Rooted, with Busybox

Thanks to Mikeyinid and TheJesus for providing the stock img files and flashable recovery zip. I used them more than once on my own device, and got frustrated at having to re-root it every time. To speed things up I decided to create a pre-rooted zip with busybox installed.
Feel free to use it as you see fit. If you format /system before you install this TWRP will warn you that there is no OS installed, but it's wrong, it will boot.

Flash this via TWRP, no wipe should be needed, but it can't hurt.
Forgive the stupid question, but this isn't a flashable stock ROM is it? New to LG so I'm not wanting to jack my phone up stupid.

No problem, it is flashable, almost stock. Check this thread for full stock, without busybox or root if you want to take an OTA update or something.

Almost stock? Are you saying this only because it has root and busybox? It does not overwrite recovery, correct?

yes, exactly. I'm just trying to be clear that it is not completely stock because there have been additional files added to the system image. It will not overwrite recovery, only reflash the system and boot partitions.

This is for the h901 which is the Tmo variant just fyi. So yeah you are good.
WiFi calling works fine. The only thing that breaks it sort off is installing xposed and that only breaks it if you don't have LTE at all. If at home you can use WiFi but it has to see LTE signal as well. If you are In. area with no LTE or if airlane mode on with just WiFi on it wont work.

You have to unlock your bootloader first by sending commands over adb after booting into fastboot then you'll have to download the twrp file and flash that over the stock recovery using adb again

flash stock. via twrp?

Hey guys, I was hoping to flash a pure stock 7.x preferably via twrp.
A buddy of mine a year ago and me to flash pure Nexus for him but now needs a stock phone for business security net purposes.
Is there a link for this? I've searched and have come up short.
I'm guessing it'll have to update bootloader, radio and kernel as well?
I know how to do this via command line. Was really hoping for a way to do it on the fly since this is not my phone and taking a PC for a TWRP ready device is a hassle.

This should be a relatively easy thing so I'm surprised it doesn't exist
there is no reason for it to HAVE to be twrp flashable, just google for "NEXUS ROOT TOOLKIT" you will see on there restore to stock, and re-lock boot-loader, not positive but i think twrp cant flash stock unrooted images, i could be wrong

TWRP can flash a stock image if someone creates it. Unless there is something odd about the nexus, but I doubt that. The only thing that shouldn't be flashed stock would be recovery.
I don't think I need to use some toolkit... adb and fastboot commands are simple enough.
I was hoping to avoid needing a PC at another persons house, I mean that is kinda the point of twrp.
I am surprised this doesn't exist. It does for every other device I've owned. It's honestly just a wiped clean, twrp backup of a stock device with TWRP installed.
If I owned the device I would make it for you guys. It seems something that is lacking that is really handy.
I guess I'll round up a laptop. Thanks for the links and suggestions.
Google has done that for you already. Just unpack the archive you choose and the four images are in there.

Different Google search gave this. I can find nothing else on TWRP site or G+
Appears you can also use FlashFire.
Thanks for the help.
OP could flash one of the stock lite ROMs in the development forum and get the TWRP-flashable stock ROM he's looking for. Danvdh and tupac4u both offer one that is nothing more a debloated stock ROM.
TWRP is able to flash system images from 3.0.2 and on. Just unpack the archive and select install img. Remember to flash stock kernel and newest radio and bootloader too (bare in mind that flashable bootloader is harder to find. You might have to find older one and update the files inside on your own). Afterwards flash stock recovery and lock bootloader with a zip. Now you can just reboot it. It's not that hard.

I went ahead and simply flashed him 100% stock via flash and fastboot.
This is probably resolved now, just adding info though. I had flashed stock 7.1.1 zip downloaded from google via twrp 3.0.3.0. It removed twrp itself too and I was back on stock.
