I am admittedly a noob, but I have searched exhaustively, and cannot find out how to accomplish this without installing another ROM. I was able to get a used N1 that is stock and unrooted to use on an upcoming trip overseas. I hoped to use it while I was there, but recently found out that I would need VPN access to access many services.
I just got the 2.3.6 update for the N1, but found out my phone has to be rooted for OpenVPN to work. Is there a tool that I can use to root this phone, leaving stock Android on it? I'm leaving in a couple of days and don't really have a lot of time to learn about installing a custom ROM or time to install that custom ROM.
Thanks for your help.
This is covered in the wiki I believe, but the short of it goes:
1) "oem fastboot unlock"
2) Flash new recovery image (I prefer AmonRA, CWM is good too though) from fastboot
3) Once you have your new recovery, flash the super user zip
4) All done, you now have root access.
This is a pretty good guide (from the wiki): http://forum.xda-developers.com/showthread.php?t=636795

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.
hi everyone! i just had my nexus one. i bought it from someone and i don't know if it's already rooted or not. Im already on FRG83D 2.2.1.
1.How do I know that my fone is already rooted?

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'm not sure if I'm posting this in the right section, this is my first question. So I decided to finally root my nexus one, mostly to take advantage of the newly integrated wi-fi calling feature in the new cyanmod. i was able to unlock it through fastboot, it now shows the lock when the phone boots up, but it doesnt appear to be unlocked. apps requiring root like rom manager, setcpu, etc. don't seem to be detecting that the phone is rooted. when i first open rom manager i get the message "you must root your phone for rom manager to function. superuser wasnot found at "/system/bim/su" or "/system/xbin/su". use google search on your computerto find instructions on how to root your phone." then when i select to flash a rom it says "an error occurred while attemping to run privileged commands". i tried uninstalling and reinstalling rom manager, rebooting, etc.. no luck. i've been searching threads for hours. please help!
You haven't rooted your phone.
Unlocking the bootloader just allows you to install unofficial images. You can now install a rooted image, to save yourself the trouble of having to root one.
First thing you probably want to do is install a custom recovery, which can then be used to make backups and install custom ROMs, etc.
Go find a custom recovery (look in the wiki), and install via fastboot. Stay away from Clockwork 3.xx...

mm installing a recovery will not root the phone either...
You need to root the phone (superoneclick works well)
http://forum.xda-developers.com/showthread.php?t=803682
If the bootloader is unlocked, you don't need to root the current ROM, unless you plan on keeping it, which the OP obviously doesn't (because why else would anyone download ROM Manager?)...
With an unlocked bootloader you can just flash any system image you want. You probably still want a custom recovery though, so you might as well flash recovery first, and then use that to flash ROMs...

thought it was okkay if you are directly flashing 3.something and not upgrading it from a previous release?
Amon RA is the best though...

#1-"com.tmobile.pr.adapt (10001) has been granted superuser permissions for an interactive shell" pops up on my screen every 30 seconds on the bottom of my screen in a grey box.
#2- i also noticed that i can accept and recieve calls but i can not hear, nor can the other person hear me. if i use hangouts video call, skype, etc it works fine.
#3-i also tried to get rom manager to make a recovery and it says it needs to get CWD recovery to install a new software, the first thing we need to do is install a up to date version, we will begin that process now... etc.. then it says to get started you must first sset up a custom recovery, it gives two options a samsung galaxy s3 on metro pcs or a samsung previal 2 on boost mobile, or device not listed, when i click that it says "SM-G920T does not have an officially supported CWDR yet. Have you installed a CWD based recovery manually?" so im not sure what to do from there, or if i even need that. i have been a iphone user since day one went to android after reading up a lot on it, although rooting is quite different than jailbreaking it seems, i am incredibly excited to get started if i can get past these little problems and get started and figure everything out. ANY advice, or anwsers to these problems would be Greatly appreciated! thanks!
Also i went to dev options in settings and noticed the "OEM unlocking- allow the bootloader to be unlocker" was turned off, i dont know if this is necessary to root if i did something wrong by not turning it on or what, or if it may fix any problems above if i turn it on now. thanks!
I have a samsung Galaxy S6 (SM_G920T) . i Rooted and did not trip Knox, Although i did just remember that my fingerprint sensor is not working either.
Thank you guys so much this si a incredible forum i have spent hours and hours reading and researching before making this post i appreciate it so much!
#1 Freeze that ****. Use some root tool to freeze that T-mobile apk, seems u gave it root permissions at some point. I believe there are a lot of apps that you will want to do the same.
#2 ? No idea. Stock rom/kernel?
#3 What is this I don't even. Don't do that. Go to TWRP's official web, get your zeroflte (SM-GT920T) twrp and flash it via ODIN, or else get the recovery.img and use flashify. All that assuming you want a custom recovery.
You will need to unlock the bootloader if you are on 5.1.1. I believe locked will prevent changes or wiping anything on the OS partitions, even recovery (can someone confirm?)
I believe jailbraking and rooting should be pretty much similar, if not the same, as both target to grant the user root access to do whatever he pleases on the OS.
Welcome to android btw.
How did you root? Sounds like you used the modified sboot which causes no sounds in calls and nonfunctional fingerprint scanner. If so, flash back to stock and use a different rooting method. The rest, pretty much what the above poster stated
Root
I rooted using the version that I found the only one that works it seemed like, went to Odin put my phone In download mode and then put the boot loader download in BL and the. Put a something unikernel.sbin I believe, whatever the guide said also then it was done. I thought you couldn't use the twrp or custom recovery etc on tmobile one yet but I just read a thing about xtrestolite odex pure v2 which says it's for 5.1.1 and my model of phone but in the guide it says to root using CF auto root and a link there to it but the link doesn't have my phone on the list that the guide that clearly is my phone says to use I don't know if I'm missing something but I want to use it I understand most of it but I don't know if I need to unropt first and re root then use Odin and flash twrp that's supported on my phone then use that to recover the rom. Etc. The kernel that says is used in the guide is the same one I downloaded so do I need to remove it all then let it do that or?
Sorry if this didn't make sense I'm halfway there between confused and understood I have spent the last 10 hours reading and trying to figure this out though lol. Thanks guys!
Also
Sorry for adding more but also how do I flash back to stock? Search for the download to the stock image of my phone? Also I could only find one way of rooting everything else said it wasn't working yet or am I missing a big portion of something here?
Just flash the 5.1.1 firmware to return to stock. To root, flash unikernel with Odin. The other method you used was to not trip knox, but as you experienced has side effects. I had to Odin back to 5.1.1 myself. Can't have those issues
thanks!
so how do i flash back to 5.1.1? find the ling to completely stock 5.1.1 and flash through odin in the same spot and same way i flashed the kernel to root? also.. i rooted with " s6_UniKernel_v2-0003-ODIN.tar" is that not the one you were talking about?

Yes, flashing to 5.1.1 works exactly like that. You need to get the version for your model (very important on this one) and then simply place that file in the AP field of ODIN while the device is in recovery mode. It is normal for ODIN to freeze for 2 minutes while verifying. Make sure to use a MD5 checker tool on the firmware before flashing.
Rooting has historically required more technical savvy and balls than jailbreaking, but PingPong made rooting the S6 brain-dead simple. CF-Auto root is still pretty painless, but you must make sure you have the right zip for your device.
Anyhoo, the quickest & easiest way to restore phone calls & fingerprint scan is to use Odin to get back to bone stock.
Next, use PingPong to root. After rooting, "com.tmobile.pr.adapt" will ask for root access. That is T-Mobile's "phone home" app and sends info about your device (probably including root status). Deny it root access and make sure you check "Remember my choice", and it won't bother you again. You will not lose any functionality by denying it root, so terminate that crap.
Don't bother with rom manager. CWM is archaic. If you want a custom recovery, use TWRP. You can install TWRP either using Odin or TWRP Manager app (it's free).
Good luck and have fun with your S6

Are you still rooted? If so, and if you are experiencing the call audio issue, go flash AOU's kernel. He has made a kernel for the tmo s6. that should eliminate your call audio issue. The finger print scanner is the only issue with flashing his kernel. Also, I rooted with the modded sboot, his TWRP and kernel, and I didn't trip knox
http://forum.xda-developers.com/tmo...recovery-twrp2-8-6-0-g925t-5-1-1-of6-t3143002
I'm a bit slow to realize this, but after updating to T mobile's latest 20b firmware (lollipop 5.0x), it lost root. I then tried to root it, using the three methods mentioned here: http://forum.xda-developers.com/showthread.php?t=2732311.
Towelroot clearly doesn't work anymore. The zip file in the above thread couldn't be flashed since there's no recovery operation possible (just showing an android with ! in a triangle sign). I also tried the purpledrake, but the script doesn't run when the phone is connected with all drives installed and adb devices showing the phone. I then tried to get fastboot mode back (to install twrp/cwm recovery to flash the zip file) by following http://forum.xda-developers.com/lg-l90/general/guide-fastboot-l90-d415-t2827825 which I have done successfully before, but then couldn't do it because it requires root (doh!).
So it seems that I just lost my ability to root, unless I downgrade to a stock kitkat (10e?) from tmobile, and then towelroot/etc. assume those work.
Anyone with experience on the stock 20b firmware? Can you root it and how? I'd love to use the beautiful 12.1 Cyanogen that's available here, but the camera doesn't work right on mine. Thus stock 5.0 seems to be the best option. Many thanks.
I got a bit further on the purpledrake method, in that I had to do a clean restart on the phone and connect to usb before the script will recognize. However, it ends up giving a really quick error message after trying a temp root: "your phone is not running a compatible software version. No vulnerable mode detected. Rebooting phone."
Anyway, many thanks to @brossovitch I followed http://highonandroid.com/android-smartphones/how-to-root-lg-g-flex-2-g2-g3-on-lollipop/ and it works like a charm. I can't seem to delete this very short thread so I thought I'd wrap it up with a solution. If it seems a bit useless please remove the thread (or tell me how to do it since I can't find the "easy button"). Thanks.
My past rooting has been based on installing a ROM that is already rooted. For reasons I won't bother you with, I want to run EPE3 (have already moved to it), and I want to root it. No custom ROM>
Remembering that I am on EPE3, Is it as simple as:
Odin TWRP to replace stock recovery
Boot to TWRP
Let it install SU/Root
I've never done it that way. I'm not sure it is possible. I have typically seen the message "Root appears to not be installed, do you want to install SU?" That has been after installing a ROM that is rooted.
Thanks in advance.
