[Q] Rooting Questions; Effects and Consequences...

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'.

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?

[Q] Cyan 6.1 to Stock 2.2.2, no root? No superuser? No clockwork?

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?
Sent from my Nexus One using XDA App

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.

[How-To] Root and unlock the bootloader of the Nexus 4/5 without wiping data

This is a tutorial on how to root and unlock the bootloader of the nexus 4 without wiping any data!
Note: I'm not responsible for any damage on your phone! You choose to do these modifications and you are responsible for any problems!
I tested this on Android 4.4.3, but you may try it on other android versions, too. Please report if it works
Devices you can root using this app:
- Nexus 4: 4.4.3, 4.4.4
- Nexus 5, 4.4.3
1. Install the towelroot app (xda thread) from the project site! Please thank geohot, he made this possible!
2. Open the app and click on "make it ra1n"
3. Wait 15 seconds and the phone will reboot!
Congratulations! Your phone is rooted now!
4. Install either SuperSu or Superuser
a) In the app update your binary the "normal way" (without a custom recovery)
b)
1. Install BootUnlocker for nexus devices to unlock your bootloader! In the app, click "unlock" to unlock it!
2. Now you are able to install a custom recovery like TWRP or cwm
3. Boot up your system again, open SuperSu or Superuser and update the binary (using "TWRP/CWM")
This is it! You're rooted now and you can easily unlock/relock your bootloader using the BootUnlocker app without wiping any data
Note: This was not my work! I just wrote down some steps to root and unlock
How to unroot:
1. Reflash the stock recovery image/stock kernel/etc (only necessary if you are running a custom kernel/recovery/etc)
2. Open BootUnlocker and lock the bootloader. Now you are able to uninstall the app!
3. Open SuperSu -> Settings -> Full unroot. This will unroot your phone and the app will automatically be uninstalled.
4. Reboot and done

noob clarifications
Hey, came across your post in another post where you mentioned this method would prevent the posibility of the phone being wiped when unlocked + rooted via "traditional" methods using a PC w SDK etc. Phone at present is locked, unrooted stock Nexus 4 kitkat 4.4.4 stock.
Just wanted to clarify a few points since this is the first time I've come across a method where the phone is rooted and unlocked from within itself (I've rooted and unlocked a HTC desire back in my heydays).
--- Do I need to unlock the phone if I just want to change the kernel from stock to the Matr1x kernel? (I had taken unlocking as a given as it was the first step in every guide - there is no mention of steps on how to actually install the kernel but I was going to research that process once root and unlock was done successfully)
--- Any chance you can give steps on updating the binary the 'normal' way? (never done this before)
--- How do you install CWM using your method? Again, I have only seen it being installed via command lines from the PC
Apologies in advance for the dumb questions but searched and couldn't find any clear answers for those steps that I'm not understanding

1. To flash a kernel you have to unlock your bootloader, that's right. You just flash it using your PC and fastboot, there are many guides on how to do that
2. If your phone is rooted and you have SuperSU installed there'll be a popup and it'll tell you to update the binary before using the app. You are able to select the "normal" way then without a recovery
3. You can install CWM/TWRP using your PC in fastboot mode!
No problem, just ask :good:

Can the usual commandline methods for other things be used after this?

If you mean fastboot commands for example to flash another kernel/recovery/etc, yes! There's no difference between unlocking using this method or another "old" one, but this one doesn't wipe data

yes. can also be used flashify to flash recovery.img without PC

I think I'll give it a try then (assuming there's no risk of bricking my phone or doing irreversible damage). On that subject, is there an easy way to lock the bootloader and unroot?

I tested this on Android 4.4.4... it works fine!
Note: with TowelRoot v3 it isn't necessary reboot, but when I've tried to update SuperSu it fails so reboot and that's all
Thanks so much!

I apologize for asking so many questions but what exactly is "updating the binaries". Is that just for the app itself or does it do something to the phone?

It updates the superuser binary that got installed by Towelroot I guess

will this method work on the nexus 5?

Thanks, for the average user who doesn't use custom roms or anything really crazy, is super su or Superuser a better option? Or is it the same more or less? Thanks

These two are basically the same, as they are apps to manage the superuser permissions of other apps. You may use the one you like

That was easy
Of course I don't see this thread unitl after I spent the last hour setting everything up in Ubuntu to root the old fashioned way! Used this and was rooted in no time.

ota updates affected or not?
does using this towelroot will affect the ota updates i.e. if any ota update comes will i able to install as in the stock rom...?? please clarify this...

see towelroot only roots your device.
You can get OTA PROVIDED - You dont change any of the stock files.. Nothing should be changed.

Hi, I have rooted Nexus 4 4.4.4 with towelroot app (and I have SuperSu app).
Now, If I install custom recovery, I will lost data? With custom recovery, I will get OTA update?
Thank you

[Q] First Time Rooter, Gs6 SM-G920T, need help intresting problem cant find fix.

#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

Want to root EPE3

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.
