I'm itching to try out some of those custom kernels and ROMS that you guys have been hard at work on.. but to do that I _must_ be able to return the phone to unrooted stock when I'm done.
Is there some way that I'm not aware of to do this?
Because all the stuff I've read so far suggest that I have to customize it to be able to back it up... which means I wont have an uncustomized backup...

I have been testing the N1 for a few days, and just making sure there aren't any hardware issues before I void the warranty (possibly) through unlocking the bootloader and flashing a ROM. I would like to know if it is possible to revert to a factory settings ROM with exactly the "out of the box" settings and OS.
Backup: Unlock, install a RA-nexus recovery, save current ROM to SD, save settings with a backup app.
Restore: Start RA-nexus, recover ROM from SD, do factory settings wipe.
Is this correct?
Currently you can't relock the bootloader, you can revert everything apart from this. It does void your warranty but apparently HTC have been decent about fixing rooted N1s with hardware defects anyhow.

As @nDrg said, you can't relock the bootloader, but you can restore the phone completely to the stock ROM... download the EPE54B stock ROM, rename it to PASSIMG.zip, copy it to the SD card, enter bootloader mode. The phone will find the zip and ask you if you want to apply the update... this will restore everything to the stock EPE54B ROM
Didn't work for me, please help...
Hello,
I tried to place the above listed file on my SD (tried the one from the link on your sig, and one from another source) and could not get it to recognize the file from bootloader, nor could I flash it from zip (via recovery).
I have been searching for a way to revert to stock ROM for days now (and I have been researching) and I can't seem to find a way that I can get to work. (I am running both cyanogenmod 5.06, and modaco's sense - switch back and forth with the RA revovery screen). I can't connect reliably to wifi on either, and want the option to go back to stock.
I'm very much new to Android (and the Nexus) thus I'm probably just missing some things that are obvious to more advanced users.
I was hoping that you might be willing to post a step by step guide to reverting to stock for newbies? (Explain each step, eg. I barely know what fastboot is). Or, do you know of a guide that you could point me (and others I'm sure) to?
One might ask why I rooted and modded my device when I did not understand enough of what I was undertaking to reverse the process. One would be absolutely correct in such a question! That being said, if anyone is willing to help, it would be much appreciated.
Thanks so much,
Randy
Just curious why you'd want to go back to stock?

@prettyboy85712:
I do love both cyanogenmod and modaco's sense rom, but I haven't been able to connect via wifi on either for quite awhile (though normal network connection works fine). To be more specific, if I have been able to connect via wifi without the sim card in the phone, but not with it inserted.
As well, it seems like a good idea to be able to revert to stock if I did need to (stock updates, etc.) and I'd like to try wifi with stock, to see if it's the phone or the ROM. (My fault for not figuring out how to do this before I modded )
Thanks so much,
Randy
if u want to go completely back where u still receive ota (minus the locked bootloader that u can't change that its unlocked) u can download the signed secure nexus 1 Rom from modaco and then flash the boot,system,and recovery.img though fast boot go to nexus one forum and search rolling back to stock Rom it gives detailed instructions on how to do it I did it to make sure it works and was simple it is and u even get ota updates from Google hope this helps if u need any help just send me a pm good luck let us know how it goes

I have been trying the stock 2.2 KB1 ROM and am ready to move back to a custom ROM. I read somewhere that you should not uses the 1 click back to stock, but 'use the files', whatever that means.
Can someone clarify for me the correct method to get back to stock, so that I can move to a custom ROM?
NOTE: I have done several custom ROMS from here in the past, my only uncertainty is correct method to get off of KB1.
I am not sure there is any reason to go back to "stock" as long as you are rooted and have changed the recovery to allow for unsigned zips you should be able to flash straight from there. Going back to "stock" should have no baring on your success in flashing here, especially if you are using no lag fix curretnly on KB1
Thanks. I do have a kernel wiht a lag fix.
Maybe what I should do is:
Turn off lagfix
put stock kernel back on
(Of course back up all stuff)
Hard reset back to stock
install new ROM
I am used to the mantra: Hard rest; master clear; etc.
Hello guys.
Before I go into it, let me start by saying I'm a complete noob at these things.
A couple of months ago (following guide on the net), I rooted my Optimus P990 and installed my first custom ROM.
Tonight I looked on the net to look at how to restore my device to stock.
I followed this guide.....
http://forum.xda-developers.com/showthread.php?t=1327599
It didn't work!!!!
Although the phone is still working, I have completely lost internet connection on network and wireless.
I'm worried about trying anything else in case I mess my phone up!!
Can anyone out there help me restore back to stock in noob dialogue??
Thanks in advance
Make a backup of everything.
Then go to recovery and wipe everything!
Perform a fresh install of your current rom + kernel combination.
Boot phone and everything should work now don't forget to restore your backups.
Thanks for the quick reply.
Will try it tomorrow.
Stupid question but what is the kernal?
Every rom comes with stock kernel, which is more or less a sort of 'driver' for your phone. Anyway, you don't really have to know what it is, only what you can do with it.
Custom kernels allow you to overclock your CPU frequency, this will make your phone faster and smoother. For example, stock kernel only allows your CPUto clock at the standard 1.0 Ghz, and custom kernels will let you overclock to 1.5 Ghz.
Custom kernels also allows you to Undervolt your phone. This means that you can turn down the voltages used at each CPU frequency. This will improve battery life. Custom kernels do much more things... But these two are the most important.
Look at my signature for the ETaNa Kernel, and read it for more information.
Ah ok thanks.
Is there a stock ROM that your aware of?
Sorry. When I say stock I mean revert my phone back to how it was when I first got it.

Have you tried restoring it using LG's PC Suite?
No not yet. I'm currently using a custom ROM. Cant remember which one it is.
Would an update via LG's PC Suite overwrite this firmware??
To reach your goal you must flash with nvflash technique, search in dev section thread about this. It will restore a stock phone, erasing recovery and root.
Lg PC suite won't be able to flash over a modified phone.
Ok. Thanks. What's the risk to my phone?

If you want to restore your phone to stock then head over to the MoDaCo site and look for a pinned topic in section on the LG O2X entitled "NVflash stock ROM release."
Following the instructions will restore the stock ROM from March 2011 to your phone.
I've been trying to root/install a custom ROM on my HTC One all day and it has been a nightmare throughout. The custom ROM I got did not work correctly, had tons of errors on the simplest tasks. But then I tried to restore a stock ROM and it got stuck on the bootloader. I was able to get a restore on the phone, but I didn't have a functioning ROM I could actually restore with.

PM me and I will see if I can help, I need more info on what you did to get to this point....
You should be able to get it back. I have found that the HTC One isn't the easiest device to brick.
Just give us some more details & the users here can most likely get you up & running again.
Agree.. a Galaxy S2 the One definitely is not.

Can you supply more info? What does your bootloader say?
What rom did you flash to get into this situation?
So I ordered this phone yesterday and I want to try some custom roms on it but I don't know if rooting while on Next would be a safe idea. I'm positive i can root and flash a rom with no problems but if i wanna switch phones in 18 months will I still be able to?
If it just needs to be the way they shipped it, will flashing a stock rom and un-rooting do the trick?
Thank you all in advance, and keep up the great work. Happy rooting. :highfive:
I would assume you would be in the clear as long as you dont trip the Knox counter. It would be a safe bet to un-root it and such when you take it back in to trade for a new phone.
