[Q] How to get stock Froyo for Nexus One

Hey guys, I just bought a Nexus One off of craigslist. The guy that I bought it from has CyanogenMod-6.0.0-N1 on it right now. Im not really experienced with flashing custom roms and rooting or any of that stuff. I put Froyo on my Captivate when I had and thats it. What I would like to do is to get my Nexus One back on stock Froyo so I can start with a clean slate. Im not sure of everything that the previous owner did to the phone and Ive been having a couple of issues with it, so I just want to start over so I know exactly what is on the phone. So what I need to know is how I can do this.
-Where can I find a stock Froyo file?
-How do I put it on my Nexus One? Do I have to erase the CyanogenMod first?
-Any other hints or good roms that you guys would suggest.
-Is there a way to back up my phone so I dont have to reinstall all of my apps?
Im sorry if there is already another thread like this. I couldnt find it. Thank you for any help.

I did exactly what you did. I used the Passimg.zip method http://forum.xda-developers.com/wik...des_&_Tutorials#Unroot_.2F_Restore_your_Nexus Was easy as pie. But yeah i didn't need to do backup / restore of apps as it was a new phone. You can't use Titanium Backup without root, but the market as a few other apps that let you backup apps to SD card.
All info including the Froyo ROM files are linked from the wiki. I went with FRG33 and then updated to FRG83.

Thank you. I was reading through the wiki post and I wasn't sure if the files were updated because the original post date was a while ago. So if I do the method that you did, will it unroot my phone? It is rooted right now.

Yes it will unroot it, flash the stock rom and will also flash stock recovery. So if you have a custom recovery installed that will go away too. Plus all your data and apps.

Is there any way to do this without a functioning power button? The only way to select things in the bootloader is with it.

My bootloader is locked, and I'd like to keep it that way. I'm sending it in to HTC and want it to go as smoothly as possible.
Just as an FYI, what I did to get back to stock:
From CM6.0 I flashed clockwork recovery
from clockwork I flashed 4.06 radio (was on 5.08)
flashed stock unrooted FRF91 from an update.zip
used flash_image in ADB from recovery to flash a stock recovery.img pulled from a FRF91 PASSIMG.
Everything works and is 100% stock now.

Sounds like you're all over it then...

Wait, didn't you need to be rooted to flash back the stock recovery?

I was still rooted in clockwork. Using flash_image put it back to stock unrooted recovery.
As it stands I have stock unrooted everything including recovery.

Oh i see, thanks for the details

[Q] what now?

i was running rooted stock. Did forever root, flashed update 893, flashed liberty 3 rom. I noticed that the version went back to 886 so i did oneclick instead of backup to try again. While running oneclick i got INFOPreinstallation error on the boot.img write. Everything else flashed then i tried to root and it gave me an error as well. My phone is running fine but i cant root. Is my phone done or can o root again?

think you may have turned yours into a bastard hybrid
it can be fixed, just have to find the fix, it's linked in one of the .893 threads

Repercussions of going to .893?

So I rooted, using one click method, backed up stock .886 and installed blurry 2.0, based on .893. I know now that the kernal and radios are changed from .886. Does this render my stock back up of .886 useless? Also, what if the OTA update coming in November is actually different than .893, will I be able to update to what ever that may be?

I would take an educated guess and say yes your 886 backups are trash, but don't take my word on that.
If you made those backups through ROM Manager, you're in luck.

That app can extract apps, contacts, and SMS/MMS from Nandroid backups done through ROM Manager.

Im loving blurry just fine and see no reason to go back, but I just hope I didnt cut off my nose to spite my face in regards to future updates.

So I did a data reset in bootstrap, and reinstalled my stock .886 back up, and it installed fine. Rebooted and everything worked as it should.

If you just install 2.0 over stock, you do not get the .893 radio or kernal. You only get the system. To get the radio and kernal you need to to go back to stock, do the permanent root method, install the cheesecake app, then update to .893 through cheesecake, and then flash 2.0. If at that point you flash .886 again, you would have the .893 radio and kernal, and the .886 system. Because the bootloader is locked, you cannot flash a new kernal or radio via cwm.

Sooooo by flashing blurr3y 2.0 in cwm I never got .893 radio/kernel?

Thanks for putting that guide up Tivo. I figure when the next update comes out, you might have to be back with the .886 and I was wondering whether there was a way to downgrade the radio and kernal to stock after going to .893.

The next update IS 893, I've already gotten confirmation of that.

Rootable?
Tivo, will the new bionics being shipped with .893 be rootable? Will they need to be rolled back per the method you detailed here ?

We will have to wait and see what root methods work after the ota is released. Painfully to wait, I know.

It will revert you back to system 886, but your kernel/radio will stay with whatever update you installed. I currently have a hybrid going on. 5.5.893 system and 5.6.893 kernel.

[Q] ?

I recently reflashed stock 886 from 893 leak after i read some threads about maybe getting the ota but for some reason zumo and lets golf are gone. Any ansewers? I tried to flash the ota anyway through stock recovery and i get the error message tmp/sideload/package.zip error. I know that having the leaked kernel could keep me from doing the ota but any ansewers would help. Thanks!

just flash the system file from the fxz and they will come back. strange that didnt come back before when you flashed.

Yeah thats what i thought. The only thing is that ive had trouble with the fxz. I cant ever get it to work properly. It never makes it past the first step. Ill keep on tryn and see. Released always leaves them out. Thanks for the info!

leaked 5.5.893 to 5.9.901?

I tried updating from the leaked 5.5.893 to this new 5.9.901 with no luck. Has anyone have any luck with this? If so how did you do it?

Throw it on the sd card, use stock recovery. What method did you use and what error are you getting?

I put it on the sd card. Tried from stock recovery and its failing at the verification. Tried to install as a zip.

Then I don't believe you're on 5.5.893. You're SURE you're not on 5.7.893? Cause if you're on 5.7.893 then you're stuck like the rest of us.

If you are on the leaked 5.5.893 and not the official OTA version, then it is possible that the checksums are different between the two versions and it fails the asserts in the updater-script.
The important thing to note is that the error messages are very specific and will tell you which file is failing. Then you can fix it, if at all possible, dependent on what was changed and how.

I thought someone checked the CRC's for the leaked vs OTA and they were identical?

Not sure if anyone has seen or tried this yet, but the error I get (running 5.7.893) regards two attributes in the build.prop file. Gonna try modding them to see if the update takes afterwards.

Don't bother. I spent a lot of time on this last night. I went so far as to put 5.5.893 *system* on and tried to flash from that. (Obviously with boot image from 5.7.893 still). It got past the build.prop error and gave me a boot error. Meaning it fails asserting the boot image. No chance for this update to work for us I'm afraid.

I am on the leaked 5.5.893. I'm on the liberty rom. Would I have to put my phone all the way back to stock? Then start from there? At one time I had restored my phoned and did the 43v3r root and my system version went from the 5.5.893 to 5.5.886. Is that my culprit right there? Even though my radio and kernel is still from 5.5.893?

Woa woa woa. Slow down. You're trying to apply this over a custom rom? Is that what you're saying? That definitely won't work. It has to be stock system for the version that the update is made for. So, in this case, you need stock 5.5.893. The kernel and radio are fine as a custom rom can't touch those. But you will need to restore stock 5.5.893 if you want to apply the update to get the new kernel and radio. Then you can put your rom back on. Hope that helps!

Do I need to reflash the original bionic stock ROM with RSD lite, then flash the leaked 5.5.893 and then flash to 5.9.901?

If you made a nandroid backup of your clean 5.5.893 installation then restoring that would be the easiest method to get the 5.5.901 to install properly.
If you have changed anything at all in your system beyond simply rooting and mount-ext3.sh for permanent root, then the update will fail.

No don't do that. For sure don't do that as it will not work. You didn't make a backup of the stock rom when you did the 5.5.893 update before putting a custom rom on?? UGH. If that's the case and you don't have a nandroid backup of 5.5.893 then this is going to be a pain. Not impossible but will cause you some headaches. First thing's first. Go make a nandroid backup of your existing rom install. I'll see if I can put some steps together that'll get you upgraded.

But not with RSD using the FXZ now that he's on 5.5.893, yea? That'd be...bad.

1) http://rootzwiki.com/topic/5484-r3l...he-bionic-v21/page__view__findpost__p__127684
Get that, unzip it, run it, and choose option 1. That will put you back on 5.5.886 stock *system* but will not touch anything else. And will of course, will install permanent root.
2) http://www.multiupload.com/0ZEN69NGO2
Get that, throw it on the SD card, and boot to stock recovery. Flash it.
3) Now you are ready to try flashing 5.9.901 again
4) NANDROID THAT THING
Then restore your custom rom and you should be good to go. CZ, did I miss anything?

I've lost my nandroids backup. . I have made a new nandroid backup of this current setup incase I screw something up.. I am unable to restore back to fully stock at this time which I'm rather upset about.. Am I screwed?

Make sure you have a nandroid of your current (custom, apparently) rom. Then do the steps I outlined above.

Just to reiterate, this will not work for those of us on 5.7.893, correct?

No it will not. Nothing will at this point in time.

awesome. It worked. I am now 5.9.901!!!! Thanks for the help... And I kept root!!!

Grumble grumble lucky jerk... J/K I'm sincerely glad that worked for you. *NANDROID*.

WHAT?!!
I am on 5.7.893
You guys mean to tell me that even if I nandroid back, to my clean back-up of 5.5.893... This 901 update will still fail??!!
Is it checking the kernel also? I have a nandroid that is completely stock so if I flash back to that this 901 update should go unless it checks the kernel version too.
