A friend rooted his 2.2 installation to install some additional apps which requires root, e.g. a firewall. He now wants to upgrade to 2.3.3, and still keep his apps/settings/messages without a manual backup.
Will it work to just flash the OTA zips found here? We're aware that he will loose root.

Sorry for being a noob and asking this if there is a simple answer. I searched but couldnt find the right answer.
Ok so Ive been real happy so far with Stock n1 and universal androot. I love the root apps.
Now that the update is out (2.2.1. frg83) I wanted to update and still have root access on stock. I was not able to update because i had deleted stock apps like amazon, twitter, etc with titanium.
I had to flash a stock rom and then update to 2.2.1 worked, BUT no root access.
I even unlocked the bootloader to see if that would give me instant root but it didnt.
How can i go about getting root access on my n1 with 2.2.1. ? I want to run a stock rom and use rooted apps like titanium. Also to get future updates like gingerbread OTA.
I do not want a custom rom like cyanogen. Just stock 2.2.1. with root access.
whats the easiest way to achieve this?
I tried installing amon ra, and it still wouldnt give me root access, couldnt install superuser, ect.
please help.
Hi
I am currently running stock unrooted, locked N1 with Froyo FRF91 (AT&T). After having numerous problems (screen calibration being the most frustrating one), I did a factory reset and re-installed and reconfigured my apps, restored my home screen, etc all manually, as if a brand new user and device. THIS WAS TIME CONSUMING!
I am looking for an app that will effectively take an image of my N1 (similar to Norton Ghost for the PC) that will restore OS, APPS, and Data. I believe I will need to be rooted to use such an app, and am looking for any recommendations for this type of backup (Titanium Backup OR ?). I DO NOT WANT TO UNLOCK THE BOOTLOADER!
I also would like to upgrade to FRG83 and have been clicking "Install Later" to the nag screen, because after reading many issues with the FRG83 build, I would like a way to "ROLL BACK" to FRF91 if I have problems (like not being able to connect to Exchange).
So, I am seeking advice and comment on the following steps I think I should take to achieve the above mentioned "Roll Back", IMAGE BACKUP goal.
Here are my thoughts, in order of what I should do.
1) Since I am on FRF91, use Universal androot to root my device. Does this install all I require? ie. Busybox, su.
2) After rooting, install Titanium Backup or similar backup app (Recommendations welcomed), to take an image of the device, for roll back if needed. Do I need any other software (AMON RA, etc) or will Titanium Backup be all I need?
3) Install the FRG83 update (either OTA or from download). WILL THIS INSTALL TO A ROOTED device? I know I will lose root, but does it install OK?
4) Use rageagainstthecage to re-root.
Am I missing any steps? Any thoughts? Are these the steps you would take if you had an unrooted, locked FRF91 device and wanted to root it?
Any help or advice is greatly appreciated.
Thanks

That would work ... though I would simply do the OTA and then root & run Titanium Backup.
Thanks Nexusdue
Although, if I apply the OTA first, want I lose the ability to "roll back" to FRF91 if I want to?
Since you can root FRG83, you should always be able to flash any ROM.
I think you can also roll back to an official ROM "unrooted" but I haven't tried it, so I don't know.
Sorry for the wall of text and for being a total noob and thank you for all your help !
So I've been researching all night (read the wiki to no avail too; so please don't simply direct me there) and I have some unanswered noob rooting questions questions and need general reassurance...
Basically I want is full and lasting root permissions on FRG83D 2.2.1 so I can remove system apps (twitter, amazon, etc...) through terminal commands and MAYBE a unlocked boot loader to flash a custom recovery image (Amon_RA) so I can make full nandroid backups.
1) It seems to me that unlocking the bootloader is a more flexible and permanent way to achieve root, as opposed to other '1-click' type methods in the face of firmware updates (2.3...), which would just disable root and it might not be re-achievable till another exploit is found whereas with an unlocked bootloader I can flash w/e I want?
2) Is it possible to enable root and use terminal on my n1 without some "superuser.apk" program? In order to do this would I use an insecure superboot and manually deploy SU?
3) How can I make a backup before rooting if I'm not rooted? I've been using my device for 8 months so there's a lot of stuff on there...
3a) If I can't make a full backup where can I find signed stock recovery images and boot images or updates zips so I can reflash them if I need to?
4) I believe if I superboot.img and leave everything (ROM and Recovery) stock will I still be able to receive and install OTA updates...?
4a) Can someone explain the difference between himem with updated wifi driver and not? I think himem removes permanent virtual address mapping so memory can be used for running applications. Asides from having more memory what are the tangible benefits or downsides to this? Would it make the system faster?Would I be able to multitask more apps before the system quits some because of lacking resources? Would the use of this extra memory inhibit system processes because there is no longer its own personal memory map?
4b) Will installing OTA updates remove root permission? If so, would simply flashing superboot.img re-grant me those permissions? But it would seem I need an updated superboot.img for the appropriate newer build(?). Is the development of superboot images still active and timely?
5) How important are OTAs and the stock recovery image? It would seem if I'm going to do any system moding (even just removing twitter/amazon) I should have a full and function Nandroid backup and would therefor need a custom recovery image- at the sake of missing OTAs (not important mainly because applying them would disable root etc anyway?)?
6) With root permissions and stock everything do I have to worry about manual baseband and radio updates? What about with a custom recovery image?
7) Apps2SD+ doesn't work with stock roms period and I would need a compatible custom rom?
Thanks again.
actually you can flash a recovery image without unlocking boot loader
1. Unlocking bootloader voids warranty and it is the official way to offer you the ability to install third-party roms.
You may get root without unlocking bootloader if you're using an old build. I think there are ways to root frg91 and frg83 without unlocking boot loader), then after you get root, you flash a recovery image, and then install whichever Rom you like. Don't bother with those official release, there will always be someone to release a rooted 2.3 rom.
2. not sure but from security's point of view it's better to have super user GUI program, because not all applications should get root
3. don't know sorry
4. Yes, there are lots of people revert back to stock ROM just for getting next OTA.
4a. I personally have never ran out of memory on my Nexus One, I do want to multi task as much as possible, however no matter how I set low mem killer, Android still automatically kills apps according to oom value (or something like that)
4b. If you get a successful OTA then definitely root is removed, and probably your recovery will revert to stock recovery too, thus you have to re-root..
5. I'd suggest to wait for someone to mod OTA 2.3 to make it rooted, then you flash the rom through recovery.
6. You can freely upgrade baseband (it's radio, the same thing) when you have a custom recovery.
7. There are mainly two ways to App2SD, one is Froyo implementation which works with stock Froyo rom, another way is to use App2Ext which requires root.
houzuoguo pretty much summed it up. I'll add what I can.
3) There is backup software in the market that can backup data without root, although it is not as powerful or thorough as the apps that require root.
3a) You can go back to a stock ROM. I believe there is a sticky round here of ROMs that has some stock ROMs in it. I know someone with a N1 that flashed a CM ROM, didn't like it, flashed a stock ROM, and got the OTA afterwards.
5) Even before an OTA is pushed there are ROMs floating around with the latest and greatest. After the OTAs are pushed you see a lot of very good, stable ROMs based off of them with all features working properly. You can do more with the custom ROMs and recovery images than you could ever do with the stock stuff.
7) DarkTremor's Apps2SD script will not only give you better A2SD than what is built into Froyo but it will give you a few more very useful terminal commands that I can't live without. Good stuff.

1. Check if there's application named 'superuser'. Or install any terminal emulator; run it, type 'su'.

Thanks guy!
I think I'm going to superoneclick to get root; back up with titanium and remove the system apps I don't want.
From there I'll be able to flash a custom recovery if I want to get more custom.
I'm probably going to wait till 2.3 comes out cause it's right around the corner; Or did they fix the superoneclick exploit in 2.3...?
Also, doesn't Apps2ext require a custom rom that supports it? i.e. it wouldn't work if I had root and was running a stock rom anyway?
I am a noob.
I followed some instructions to prepare my N1 for the OTA 2.3.3 update and messed some things up. I cleared EVERYTHING from Clokwork recovery, but, then phone would not boot anymore. So I manually loaded a Cyan 6.1 and GApps zip and got the phoen to load. Finally ran clockwork, rom manager, backed it up. Then I downloaded the stock image FR91 from ROM manager, clear cache/data and rebooted. Phone updated from 2.2 to 2.2.2. Now I have all my apps back and stock ROM, but superuser will not work. I cannot flash clockwork now, and cannot use ROm manager. Titanium prompted me to update superuser binary thru a zip file, but it will not run. Now, I tried to access recovery thru bootloader, but it just give me the Android with the ! and nothing more.
Alos, ROM manager keeps saying my phoen is not rooted, but when I bought it (used) it had Cyanogen 6.1. I know it's rooted, I get the unlocked boot screen, but why the problems now? How can I regain superuser functions to use ROm manager again?
Thanks in advance.
This is what happens when people don't read and don't understand what they're doing.
ROOT is a user in OPERATING SYSTEM = Android OS.
LOCK is a property of BOOTLOADER = a program that boots the phone.
Stock = NOT ROOTED, until you root it.
UNLOCKED = allows you to flash ROMs and other partitions directly from bootloader.
The 2 have no relation whatsoever, besides one - being UNLOCKED makes it easier to gain ROOT.
This has been discussed here a zillion of times. Do yourself and XDA a favor, please, and invest some time in reading Wiki - it points to several 101's (things to know) and guides.
So in my case I have unrooted the phone and should research on how to root again?
Thanks for the reply. I suppose I just confused myself.
So if I root again this will/will not affect the OTA update?

Wiki contains rooting guide.
Rooting won't affect OTA.
Custom recovery will affect OTA, unless signature checking is turned off in it.
You will have to root it.
A stock rooted rom will get the OTA. It will update as long as you don't remove stuff from stock. Like Amazon, twitter.
Please read the wiki.

i want to get the leaked ota, but i am rooted and i cant find a way to unroot on mac. Is their anyway to unroot when your on mac? Can you just use ota rootkeeper instead?
thanks
You don't need to unroot to install the leak, just make sure all the stock bloatware apps are there. You will have to re-root after the update.
