[Q] Restore nexus one to orginal rom - Nexus One Q&A, Help & Troubleshooting

I have cyanogen mod 7.0 on my nexus one and I want to restore to its original ROM(Google ROM) also I installed rom manager on my phone ?
How can I do it ?
If I do it can I get latest update from Google?

Use the Nexus One Wiki http://forum.xda-developers.com/wik...des_&_Tutorials#Unroot_.2F_Restore_your_Nexus
or you can fastboot flash the N1 system images available at developer.htc.com
To be able to successfully update OTA directly from Google you will need to revert to stock recovery & GRI40

You don't need stock recovery for the OTA...

Why not just go and flash one of those vanila AOSP rom's? then you have almost the stock nexus feel but still keep the root and stuff like that.
Why you want to go back to stock anyways? is it just for OTA? cause those cumstum vanila roms are higher/newer version than what the OTA update would give you at the moment.

how do i get OTA back after rooting/unlocking

Hello,
How do I get OTA updates back on my N1 after rooting/unlocking and using a custom rom. What rom do I need to use to get OTA back?
Thanks
I too would like to know this.
You can't. You need stock recovery.
The only thing I have to do is flash stock recovery?
Is it even worth it
Why do you need OTA when the devs have given you the ability to update via .zip files?
You can easily go back to stock recovery using ROM Manager in the market.

[Q] Firmware update without S-OFF by switching back to StockRom and Update?

Hi everybody.
my HTC one has Viper 5.8 running with S-ON and i like it that way.
I never updated the Firmware since i moved from the 4.2.2 stock rom. (i have nandroid backup of the stock rom)
I am a bit scared doing S-OFF "just" to update firmware, hboot and radio, I know it should be easy to do, but i just don't want to.
So i thought that maybe i can flash back to the stock rom, then make the offical HTC update to 4.3 sense 6 (should also flash newest firmware right?) and then unlock the bootloader again, flash twrp and custom rom again.
Would that work? Is there something i have to pay attention to?
thx for any help!!!!

Since you don't want S-Off, that is your best option. I would follow closely @Mike1986 [GUIDE] Complete Flashing Guide | Rooting | Going Back To Stock it is for those who are S-On.
Thanks, I will follow the guide.
But I have one more question:
Can I do the official HTC update from the htc stock rom while I still have custom recovery and bootloader unlocked?
Can't find any any info if there is any risk involved not changing back first to stock recovery and bootloader relocked before doing the update.
I guess recovery will be overwritten by the official update?!?
You need stock recovery and locked bootloader to take updates

you don't need a locked bootloader to get an official ota update,however,you do need to flash a stock recovery !!.
I went through the ota update method to update my firmware as for some reason my htc one wouldn't s-off and I felt that it wasn't running as it should on custom roms with the old firmware.
I started off with a flashable zip -4.06.1540.2,developer edition then ota updates,always doing a nand backup of rom.
always pull the stock recovery image from the ota before updating...
i'm now running 5.11.1540.9 firmware and all custom roms are running good...
if you google 4.06.1540.2 dev edition flashable zip you should find it,if not,i can upload it too somewhere for you...
an official htc ota update changes your firmware and installs a stock recovery..
its a bit long winded this way,but,it was the only way for me !!

First thank you for sharing your experience.
When you say "zip -4.06.1540.2,developer edition" then you mean the rom, correct?
Why would you pull the stock recovery from the OTA before updating? What would be the consequence of leaving it in?
...
so i would download the odexed stock rom from http://forum.xda-developers.com/showthread.php?p=48111304
and afterwards flash the according recovery.img, correct?
i guess it is no problem that my phone (and their for the bootloader) was not a developer edition

yeah,it's a full flashable rom,that can be installed by custom recovery,when I say pull the stock recovery,i mean copy it to a folder on your pc,always best to have the matching recovery for your stock rom.

[Q] Stock OTA Query

I might be bringing up the same topic from the Grave. If yes, then please bare with me.
I currently on the Viper ROM with my HTC M7(European Version).
I want to go back to stock and I kind of figured out on how to do it.
I juts had few queries for you guys:
I need to S-OFF, lock the bootloader and run RUU for Stock as far as I understood. Is that right?
Now, if I am successful with the above step of getting my stock ROM on my M7, will I continue to get all the stock OTA updates from HTC like the 4.4.2 Kitkat update + sense 6? Or will i be required to do a manual update all the time?
Thanks in advance for your support.
Cheers

You will receive OTAs as normal after an ruu and can flash them as long as you stay with stock recovery and do not mess with anything in /system or stock apps in /data (just use titanium backup or similar to freeze the apps instead of removing them).
If you want, make a backup of stock recovery (or find a recovery.img to flash when OTA comes) and use a custom recovery to make a nandroid backup that way you can root and mess with /system and /data as wanted and restore the backup and flash the stock recovery when you update.

easiest way to update is with fastboot and google images here is link to images https://developers.google.com/android/nexus/images
if you want to keep data or it wont flash follow this http://www.androidpolice.com/2014/11/12/running-into-the-dreaded-missing-system-img-error-flashing-android-5-0-factory-images-heres-how-to-get-around-it/ but you need to erase data because your on a custom rom and it probably wont be compatible with stock rom once you have updated everything reflash a custom recovery or dont flash the stock one at all then flash a 5.1 rom and good to go
What about all the Bootloader and radio zips that can be flashed through TWRP? I've read about people flashing the updates while still being on their 5.0.2 ROMs and everything still works fine, I don't have access to a computer I would like to just update straight from my phone without a Computer if possible? Think I could flash the Bootloader and radio updates through TWRP then reboot n after everything is all good go back and flash the new 5.1 ROM and gapps?

i don't know if anyone has twrp flashables for the updating bootloader and radios your searching is as good as mine here i am not experienced with that i always used factory images or ota updates to update those things.
but if you happen to have a backup of your stock rom in twrp you maybe able to just go back to stock then flash back your stock recovery then update with an ota but for an ota to work it has to be all stock no root no nothing just stock.

Where to get stock recovery for ota update?

I rooted all the way back on 4.2.2 1.11.707.1 and I have cwm now. All the old stock recovery links I could find are dead and the custom roms all seem to require updated stock to be able to flash them. How would I go about updating by ota?
