Rooted and installed Cyanogenmod. How do I get back to stock if I ever need to?

I'm not too worried about undoing the rooting (unless there's an easy way) but how to I get back to Android 2.1 like I had when I first got the phone? Can I just install the stock ROM and where do I find it?
Thanks

Why would you want an unlocked bootloader with the OTA stock ROM? There is no way to relock the bootloader and regain your warranty.
CM is Android 2.1, just a better, faster version.
If you are concerned about OTA updates, the features are generally included in Cyanogen's ROM immediately upon release, but usually far before any OTA release.

No big reason why I want to right now but I like knowing there's a way to get back to stock in case something goes horribly wrong and I mess something up (and for the same reasons some of us reformat our computers often). I don't even notice a huge difference (speed and battery) running CM. I haven't installed many apps or themes though.

That's different than the stock rom, right? Is it possible to be unlocked and run the default rom that comes with the phone? Or is that combination not a possibility?

Sure you can do that, but I guess I just don't understand why...
You can always go back to stock everything except your bootloader will remain unlocked (unless someone finds a workaround or hack)
Anything you can screw up (except a bad radio flash) can be fixed by having an up to date Nandroid backup...
Just do what I do and make sure to Nandroid every other day or so. (Or before every time you change anything in the system/framework/boot/kernel etc.)

i think you can get the stock rom from here if you didnt do a nandroid backup

If i were going to sell the nexus one some time in the future, it would be good to know where the stock rom can be found. Some people don't want to be flashing ROMs all the time, and would prefer OTA updates. Once the phone is over a year old, the unlocked bootloader will be meaningless.

Simple, in the android development section at the top of the list as a sticky, [ROM] 22/Mar ERD79 -> EPE76 - Stock Nexus One images / zip / online kitchen / rooted, or heres the link, http://forum.xda-developers.com/showthread.php?t=619801, it gives you the stock rom. happy flashing

[Q] When Froyo hits, will your root and everything with it be "restored"?

BEFORE you judge me lol : I'm a new android user, and I've searched and read through the forum and FAQs alike.
Sorry if this is already answered. I've tried the search and read through the FAQs already but there's so much information my head will just explode from it.
Also I'm a fresh android user (just switched over from the iPhone, yay?). I was a very enthusiastic jailbreaker for the iPhone when I was still using that device. Hence my enthusiasm for all things "hackable" for the Android device as well.
All my blabbering aside, I'm just wondering this.
When the Froyo update hits the i9000, your root and everything with it(custom firmwares and stuff?) will be "broken" and be restore as the "stock" Froyo firmware/build right?
Am I even making sense to anyone?

for new firmware, you have to flash it, and so, everything will loss, storage in your internal and external SD will remain but all you app, mod, messages, call log, contact, etc will be lost
like you've partition your home PC with app data saved in C drive and all other documents in D drive, when you reinstall your OS, you wipe off your C and install it again and everything in D should remain (if you do it the right way )
correct me if i am wrong

We won't know for sure, but the way HTC handles Froyo updates, there is no data loss.
But to reply OP, yes, root will most probably be lost. But ability to flash custom firmware should still be available. Afterall, in the first place we don't even need root to flash custom firmwares in the first place, at least on the SGS.

So this does mean that we will be able to get the froyo update through kies even though we are running rooted custom ROM?

alright thanks for the speedy reply and clarification. i have a lot of new terms i'll need to learn for the android now. lol.

sorry, OP, are you talking about an official Samsung firmware update using kies or the one using odin3?

Most probably not. You might have to return to stock firmware to get any updates from Kies.
But what's the point? The Froyo firmware will be available in the Odin form certainly.

i think the stock official firmware update. i'm also afraid that flashing a new OS for my current 2.1 will screw up any local settings. i need to do more research about this whole flashing, rooting thing...
shall spare you guys my questions. lol.

ironic from my previous post, i'll just like to ask one simple question.
since i'm a totally new android user, i should just wait for the OFFICIAL Froyo for the SGSi9000, update it and wait for some modified version of the OS, and i'll flash it over for a speedier, more accessable phone?
(i've read the FAQ a thousand times lol.)

the official one is somewhat released near September as i remember... so you have to wait till that time to do it.... i know nothing about flashing using Kies since I am a new user to android as well
but what i am thinking is: either you flash the current firmware (JP3, JP2, etc) using Odin3 or the official firmware using the Kies, the chance is if you brick your phone, samsung will also not responsible for it, so... unless you take your phone to the customer service, you are still risking

well you definitely know more than me lol thanks for the information folks. imma root my phone, don't think there's any risk ye. wish me luck lol.

I am gonna necro this thread since I am an absolute idiot.
It took me a few days just to understand that root is not the SAME as flashing. Finally got that through my head. Hence I can keep my stock JG4 firmware while having root.
But what happens when Froyo comes along. As someone already said, we are going to lose root if we update via KIES. Then what? Do we just use the One Click Root to root our phone again? (Right now I haven't found a reason to flash to a custom ROM yet.)
I am asking this since I am sick of losing all my data in my phone every time I have to upgrade my firmware, but if I can't root my phone afterwards, titanium backup won't work.

[Q] Question before flashing mods on my Captivate

This may be a noob question but I would like to modify/flash my phone but I have a question before I do. I have done a few searches to find an answer but came up with nothing so far.
I have been browsing the forums for different mods that you can do for the Samsung Captivate. Out of all the mods that I have seen (One Click Lag Fix, Root, Cyanogen, Leaked Froyo Build, GPS settings changes, Removal of AT&T bloatware, unlocking phone for other carriers, side loading enable, and various others), they can ALL be undone using the Odin3 One-Click Stock Rom process correct?
ttp://forum.xda-developers.com/showthread.php?t=731989
Hoever, each captivate has unique phone identification information such as IMEI, Device ID, Wi-Fi MAC Address, etc? Are there any mods that change the unique information for each specific phone? If so, how does Odin3 One-Click Stock ROM process correct that? When Odin3 reflashes to "Stock" ROM, I just want to know how that works if each phone has specific information.
Thanks in advance!

yes they can be undone with odin one click, however once you stray from stock it is most likeley that you wont be able to update to the official 2.2 from att.
personally im going to wait and update to official 2.2 from att then root and nandroid backup and the fun will begin because I will have a backup of the official update with my unique device id to fall back on. in my opinion this is the safest way to make sure I dont screww myself and not be able to update. once that is done it wont be long untill someone builds a decent rom from scratch plus like I stated before I will have a nandroid backup of the update for my phone if I try something and dont like it.
If you still feel compelled I havent gone to the leaked 2.2 but I did have verry good results with stock 2.1 and voodoo lagfix on anather captivate. the phone was verry fast with verry few side effects well woth it if you really cant wait.. But just remember once you stray from stock I believe the only way you will get to 2.2 will be through these forums.

anyway whatever you get from these forums will be much faster and cleaner then stock versions...
anyway i got question about the topic - i had stock 2.1 (JF6), backuped it, tried some cognition 2.2 beta, then flashed with odin to stock and the restored my backuped jf6
did my IMEI, Device ID changed?
(wifi's mac address cannot be changed)
thanks in advance

I am speculating here.
I dont think it can change any hardware I.D info but software I.D is anather story it could possibly cause problems with the O.S interfaceing with other stuff like market.
someone with more knowledge please chime in

Theres a new app in the app store (as of a few days ago) that allows you to change your Android ID#. Called Android ID changer
Unfortunately, it won't figure out what your unique # is. If you install Cognition, you have the same ID# as everyone else.
I'm not sure about Odin - stock. My Odin 2.1 # is different than the Cognition one. Ends in 43b1. I'd be really interested to know if anyone else could check their Odin 2.1 eclair JF6 (all stock, not modified) android ID # and see if it ends the same as mine. If it's different, then that means you can always revert to JF6 to figure out your real #. If it's the same, then I guess that means for the time being your SOL for figuring that out for now.
You can always check it before making modifications....
Shadow; you are probably right, but at the end of the day software is all that matters...

Thanks for the responses. Judging from what I have been reading on the replies so far, nothing can bring me back to my original stock android 2.1 OS with all original software IDs my phone had even if I use the steps outlined in the

Just as long as you are running any of the stock eclair 2.1 without any mods all your unique id's wil display correctly, even if you have flashed to cog 2.2 or leaked 2.2 if and when you flash back to a truly stock eclair 2.1 the id's will return correct.
The android id changer app from the market will display the current android id your phone has when you open the app - it shows the current id just above the entry field where you can change your id. So download the app open it get you id write it down, save it in a safe place, then if you flash any rom the does not populate you unique id correctly you can reinstall the android id changer and enter your correct id manually.

Is [STOCK ROM] Odin3 One-Click Downloader and Drivers CAPTIVATE ONLY method a "truly stock eclair 2.1" as you mentioned in your post Davy? Also, are there any other IDs I should be aware of and take note before I flash/mod anything?
Thanks.

I believe odin 3 one click in that thread is a straight rom off a phone with samsung jf6 stock install - yes I'm fairly certain it is stock. There is another odin 3 one click for the leaked 2.2 which is obviously not stock.
If you download an app from the market named simply " ID " it still give you four of your phones id numbers for your info.
I'm pretty sure all your phones id numbers are either generated from hardware coded info or your google account - so as long as you gave properly coded software on your phone these wil always populate correct - even if you install something that messes these up of you remove the bad software replace it with good software it should then populate the id numbers correctly again.
Such as the android id in the leaked froyo that isn't being generated but simply being copied to every phone it is installed on - when you replace the froyo leak or any of the roms built off the leak with one of the stock samsung roms your phone will then generate the id correctly again.

No thread jack but i thought id ask in here.
If im rooted and ONLY rooted on 2.1 will that not allow me to update to official froyo?

maybe, maybe not. Some of the people who were rooted only (no mods) were able to update to the jh7 update. And from what I have heard mini kies has worked to update for everyone that flashed back to stock and tried to update that way - but this is all some what of a guess as we don't know exactly how att and/or samsung will role out froyo for the captivate.

You are all really funny. Your worried about getting an official OTA from AT&T so you won't mod your phones, lol. Your choice I guess but the last AT&T OTA bricked a lot of phones that had not even been rooted. The ROMS that you find on these forums are way better than any of the stock Samsung and AT&T put on them with their bloaty, buggy software. I won't do any OTA updates, I wait until the developers here fix them, remove the crap AT&T put's on them and speed them up. I give you guys credit though, staying stock sucks bad, it freaks me out to see that stock screen everytime I flash back to stock before flashing a new ROM to my phone. I only stayed stock for 2 weeks and never turned back, glad I did it too. I would've bought an I Phone 3g if I wanted to stay stock and not mod a phone. Go look around the forums and read the threads, don't just skim them or you won't learn anything. See what custom ROMS and kernels are cooking and what people are experiencing with them. We had the OTA rooted on here a few hours after the update was rolled out, you won't miss anything by not recieving it officailly from AT&T. Hell we already have some good Froyo ROMS and kernels. Keep waiting if you want but there's plenty of goodies here why wait?

Different strokes for different folks man, Its not like im using the tw3.0 and the blue bubble background lol ive customized stock 2.1 how i want it to look and its working PERFECT for ME, fast as hell, gps locks on quick etc. Flashing a rom is nice and all but the risk of bricking youre phone is high (theres always odin i know) and if stock is working for people then more power to them.

The way I look at it is, the phone belongs to you, do what you want with it or to it as you please.
but I do agree with one point above, I personally would not trust a samsung/att update to not mess up my phone. But that does not mean it won't work well for you or that you won't be happy with it that way.

IMEI can never change. I don't think your device ID can change buy your Android ID can change as you've been told by those before me. If it possible to change your WiFi MAC address, only I'm not sure how to do it. If you can do it in a full version of Linux, I don't see why it's not possible on our phones. Also, before you do any mods, make sure you backup a couple files onto your computer for safe keeping. The ones I'm talking about are in the /efs directory of your phone and relate to unlocking the phone for other networks. The second you go to mod your phone, these files will be erased and replaced with ones that are harder to get your unlock code out of.

Like mcord said above, u could do all u want, and then set it back to stock in case u run into any issue. Just be careful not to brick ur phone, and cross check if u can get into the download and recovery modes, in case ur phone gets stuck at any place.

i DID root due to one click root program, phone is fully operational got rom manager installed and oclf installed, tried titianium back up paid, didnt install, uninstalled it looking for an easy 2.2 rom to flash. but did android explorer backup.

You have to install the free version of titanium then the paid. The paid just unlocks features on the free version. It is not actually a standalone app

oK will do, what will happen after att 2.2 update, will I still be in root?? If im still in root after update will I be able to use mobile hot spot feature?

You will need to re-root your phone IF and WHEN (if ever) AT&T releases the OTA 2.2.1 Froyo update.
After you start rooting and flashing - you'll never use AT&T's update as it is.. you'll just wait for the Odin or *.zip and do it that way.

I had to return the captivate, didnt work well as a phone. I did unroot it and master reset on it so its stock.. got an aria instead, works good as phone.

Oh man... should have checked here first. Some people trade their captivates in a couple times before getting one that is "perfect". I've never seen a model that can be so different phone to phone.
Also, I hated the captivate on the stock rom and was having some huge buyers remorse. I thought I made a huge mistake not getting an iphone 4. It wasn't until I flashed a custom rom that I started to love this phone. I had the same feeling that you did, that it was a neat toy but not a good phone.

[Q] Help with best route to reflash/unlock (changing to UK)

Hi all,
I have flashed my phone a few times (actually only once to perception, and then recently back to stock before then flashing stock rogers 2.2 - as I didn't have internet at the time to use kies, even though I am US based). I am currently traveling around Europe, and will be heading to the UK soon from Sep-Dec. As such I would like to unlock the phone and use an Orange or Vodafone pay as you go sim.
Unfortunately when I tried to unlock the phone I was unable to, I am assuming because the rom on there (stock rogers 2.2) doesn't have some of the correct things...(sorry for not being more specific).
Right now my plan is to reflash back to stock 2.1 and try and unlock from there? I don't want to turn this into a "what rom should I use now" thread, but is there an good battery life 2.2 rom that would let me unlock. I've looked into flashing a 2.3 rom, but it seems like more work than I am willing to put in right now (although I'm sure it's not tooo hard, I don't have a ton of experience flashing, and I can't afford to really screw this phone up right now), especially with AT&T announcing they will be upgrading it to 2.3 sometime "soon" (hah).
Sorry I know this is a long post and not especially clear, but I'd really really appreciate the help.
thanks,
-Foofie

Hmmm, maybe flashing to gingerbread isn't as hard as I thought it was? According to this:
http://forum.xda-developers.com/showthread.php?t=1127249
it's just an odin 1 click now? Maybe it always has been and I'm an idiot, I wouldn't be surprised. So if I flash back to stock 2.1 and then flash to 2.3 using the above method (although I'm a bit confused about the extra files on that page, why do I need to change the kernel, how do I do so?) could I unlock the phone at that point? Or would I need to flash to a custom rom like cognition 5 or perception first?

Just flash to 2.1 root and unlock it from there. After that it will be unlocked and you can flash whatever. I've unlocked once six months ago flashed 1,000,001 times, still unlocked.

Ahhh thanks, this is what I was hoping to hear!
So even flashing with Odin wouldn't reset the unlocking? Doesn't Odin wipe all the phone data?

Not ALL data. The efs folder contains the imei number which is unique to each device. Just make sure and back that up (the efs folder), so if you have any network connectivity issues you can restore your imei...

Thanks.
God flashing to 2.2 the way I did was a huge mistake. Trying to flash back to stock soft bricked (hopefully that is what this is) my phone. Trying to get heimdall running now so I can use the 1 click unbrick.
