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?
2.Where can i download the stock ROM just in case the fone crashes and i want to revert?

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

Why?
Sent from my Nexus One using XDA App
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?
Yes I have read the FAQ, and I still think this is possible, if you install via custom recovery.
Currently the flashable zip generation requires root access. If there is any way to generate that flashable zip file without root then only a custom recovery would be required to install Xposed, as a custom recovery can write to /system without needing root. Since I am currently installing root only to install Xposed and then immediately removing it I would greatly appreciate an install option that doesn't require me going through the rooting process.
So my request is for the two recovery installation options not require root to generate the zip file. Thank you.
Open recovery, flash ZIP file.
You don't need at all.
That part I know. Once I have the flashable zip file I am fine. However, on my phone I cannot create the flashable zip file without root. It just fails. Hence my request.
Stupid question, but can you install recovery without root?

Yes, some manufacturers include recoveries pre-installed, but those often have restricted functionality.
Also, recovery can be installed on some phones without root with the use of a PC (again, it's brand-dependant).
And finally, a few (too few) manufacturers ship their devices with unlocked bootloader which means you can do anything you want with them.

Yep. I personally have an HTC device and they allow anyone to unlock their bootloader by filling out a form on their website. Once the bootloader is unlocked no root is required to flash a custom recovery. That is how I typically run my device no root but custom recovery. Occasionally, I revert to stock recovery to install a system update. Then I run into this issue where I have to root just to reactivate Xposed, then unroot again. I would much prefer to avoid the root/unroot part of reactivating Xposed.
I'm hoping that since it is only creating the zip file that I am asking about this is a quick and easy change.

In Moto G you can install a custom recovery and mount /system and /data (I need a custom recovery to flash SuperSU.zip), so, I think it's possible.

Not the stock recoveries, installed recoveries. I didn't think you could install TWRP or CWM without root.

Have you heard of flashtool or Odin?
Using flashmode/fastboot you can do more than with root.

I have installed both without root multiple times. Here are a few guides.
Nexus Devices (Note rooting comes after custom recovery is installed.)
General Advice (Note: First option requires root, second two do not.)
In general as long as you can unlock your bootloader no root is required. I have only ever purchased Android devices that let me unlock the bootloader, so I have always gone that route.
Again for my feature request though I just want the flashable zip generation to not require root. That (hopefully minor) change would allow a completely root free use of Xposed. Which would be wonderful for me.
Stock recovery will only flash officially signed packages. If you have a custom recovery, you can easily gain root access. So what point would it serve?

That question makes no more sense to me than a comment that Xposed does nothing more than a custom ROM, and if you can install Xposed you can install a custom ROM so what is the point of Xposed?
However, I will provide a few of my answers to your question pick your favorite.
Requiring root without needing to doesn't serve any point so why require it?
Root is required "because it replaces a file in /system/bin". However, on my phone /system/bin is write protected by the kernel, so root does not grant write access to /system/bin only recovery does, So why is root required to create a zip file that I install via recovery?
I like to be able to run apps that don't work if you are rooted. (DRM protected movies, corporate apps, etc.) so rooting causes me problems, and fully unrooting afterwards is a bit of a pain. (I have had to develop a custom script to do it efficiently.)
So, I just did some more searching and discovered that I'm not the only one who wants this. jurben requested this back in September and even wrote up the code to make it possible.
So, I went ahead and turned it into a Pull Request on GitHub. Hopefully it gets accepted.
Hey guys, I have a 64GB stock T-Mobile Galaxy S6 that I have (somewhat) debloated and so far the battery is okay.
I've heard promising reviews about XtreStoLite G920T Pure Edition ROM.
First, I want to make a backup of the STOCK ROM I currently have, but IIRC, you cannot back it up unless you root first?
I was looking into PingPongRoot so I could go back to stock just in case anything would happen but I need to know how to back it up first.
Second, I want to install the ROM and I'm pretty sure I'm correct. Do I need Odin if I use PingPongRoot?
Third, I want to install Ktoonzes kernel as well but I don't know anything about that.
So, pretty much I need help with:
1. Backup current stock ROM before rooting
2. Root with PingPong
3. Install XtreStoLite
4. Install Ktoonzes
Also, if there is anything else I should be cautious of let me know. Thanks guys!
While all of this info is easily accessible, in the spirit of giving... Here you go.
To backup, you need root.
Install SuperSu from play store, open SuperSu at least one time, then download Ping Pong Root APK and run it. It may take two tries, that's normal.
Then, to back up, either install TWRP with Flashify (downloadable from Play Store) or via Odin (Either method will trip Knox in bootloader and void Samsung warranty, will not harm phone in any way) and back up
To install ROM, Flash in TWRP recovery (if you installed TWRP in last step Knox is already tripped)
Then, use TWRP to flash Ktoonzes kernel (I recommend letting ROM boot at least once fully then going back to recovery to flash kernel)

If you don't want to void your warranty, you could back up using Chainfire's FlashFire, but note that it is an app and therefore you need to have a semi-working system to restore! Which is fine since you can flash stock using Odin, then root using PingPong and install FlashFire again. Just slightly more of a hassle.

Yes, only if you don't flash a kernel with the new ROM. You have to edit the zip and remove the boot.IMG , then edit the updater script to remove the command to wipe and flash boot.img. if this sounds too difficult to you don't try it

So how do you flash a custom ROM without a custom recovery? Recovery trips Knox...
I'm gonna need to look into this one. Been a while since I did anything with a Samsung device.

I don't think chain fire has been to open about how flashfire works (not a problem his choice). So if you want a good idea how it works look into safestrap, I'm sure it's close other than the fact safestrap doesn't need a app in a working system.

Needs a zip without the kernel... I remember seeing a ROM that mentioned not having a kernel, I guess for this reason.
I don't think any of the t-mobile ROMs come setup like that though. So I would need to go through the trouble of repackaging the ROMs myself.
May not bother and just trip the counter and flash normal. Custom kernels are often the way to go for battery life and performance.

Oh I thought you meant how flashfire boots into its recovery mode without tripping knox, yeah custom kernels and recoveries will trip knox but if the demand is high enough there are ways to use custom kernels without flashing them and someone is bound to bring it to the s6, but I'm sure the demand has to be high enough.

Its an interesting alternative to full root flashing. Preserving the warranty is good for some people.
Ever since I did pingpong root, I have been having odd issues with pandora bluetooth streaming to my car. Hopeing a custom ROM will solve this.
hi,
I would love to root my sm-g800f.
Which guide should I follow?
Thanks
What ROM? You can try flashing the correct CF Auto Root for your phone model and Android version using Odin if it using the latest Lollipop.

I have to look, so, for 'CF Auto Root' for G800FXXU1BPC3 Lollipop MR1 and
Odin.
Odin goes on PC and
CF Auto Root goes on device.
Am I right?
Both files go on PC, you used Odin to flash CF Auto Root into mobile. Seek for the files in the official page:
https://autoroot.chainfire.eu/
There are many videos on YouTube about it as most Samsung phones are rooted this way. Just make sure you use the correct file for your phone (G800F).
Backup everything you can first in case something goes wrong you may need to wipe mobile data and reflash stock ROM.
The other option is to use Odin to flash TWRP and then flash SuperSU zip from Chainfire. First, TWRP goes on PC then SuperSU Zip on phone, that you flash using TWRP. I am sure there are tutorials here about it, just pick TWRP for G800F, SuperSU is universal but some version may be needed according to your Android version. Can't help more because I have G800H and not rooted as Marshmallow was released for it and it has all I need. Good luck.

first way, I think, should be more simple.
How silly, I would root to change fonts on device.
And of course to free space, delete junkie and have control of my device.
Marshmallow is going to make me regret rooting?
You can change fonts using atock, no root needed. Also use Debloater to disable junk, no root needed either.
You can't use OTA to upgrade to MM when it arrives as it usually won't install or bootloops, so you will need to flash MM to go back to stock and upgrade then root again. Flashfire from Chainfire would be able to install OTAKU and keep root, but support to S5 mini is unkonwm, and no reports of success as far as I know.
Last but not least, flashing anything other than stock ROM through Odin will trip a Knox security counter and you'll lose warranty.

I'm stock. If I'll root I'll not be anymore stock.
If I don't root, will MM arrive OTA?

This is using stock MM on my G800H, I don't remember on Lollipop but I'm almost sure there was a similar option:

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.
