Avoid losing root if ATT forces 2.20 OTA update

I have an AT&T HOX. Came stock with 1.85.
I rooted it using the "redbend" method described here (http://forum.xda-developers.com/showthread.php?t=1709296)
(More or less, the pulling SIM card business wasn't part of the steps when I used it, but the root was successful).
I am using SuperSU to manage root access by apps.
I have not done anything beyond that.
Now, I understand, at some point, AT&T is going to force a 2.20 update on me.
My primary concern is to avoid losing root.
(I have enabled the "preserve root across OTA" in SuperSU, but not sure if its effective or not)
I've looked at the howto's for SuperCID, unlocking the bootloader, etc, and I'm not sure which I NEED, and which are optional, and/or what the pros/cons are of each...
I'd like to stay as close to "stock" as possible, but I want to ensure that I can keep root.
I'm still within my AT&T contract, and would really prefer to avoid bricking the phone.
I'm wondering what the recommendations are as to the minimum steps I should take to keep root in the event the OTA is forced on me?
Can I pre-empty the OTA by installing this? ( http://forum.xda-developers.com/showthread.php?t=1812459 )
If so, what is the safest method for installing it?
FWIW, I am a linux user, and I am comfortable with adb as well as the command line on the phone itself.
I have no windows systems, so any special tools I'd need other than adb I'd have to find a linux version.
I don't need "one click" methods, in fact I'd prefer to see/perform the individual steps and understand what they are doing.

unlock your bootloader using this method http://forum.xda-developers.com/showthread.php?t=1672284 if you don't you wont get root again afterwards.

Dont have to unlock to flash roms?
This document,
http://onexroot.com/one-x-root/root-any-htc-one-x-windowsmaclinuxattinternationalone-click-method/
Near the very bottom, suggests:
For AT&T HTC One XL and alike, if you want to install custom ROMs, you don’t have to unlock your bootloader but simply flash custom recovery in fastboot.
Is this accurate?
My ATT HOX is currently rooted, and I now have SuperCID. I assumed I would need to unlock my bootloader, but I havent done that yet.
Can I install this:
https://play.google.com/store/apps/details?id=com.s0up.goomanager
and then use it to install the "Stock Rooted AT&T 2.20.502.7" here?
http://forum.xda-developers.com/showthread.php?t=1812459
And if I do that, will this avoid AT&T OTA'ing me?
On a relatated note, would the SuperCID survive the OTA, allowing me to unlock the bootloader afterward, even if I hadnt done so already?

Completely false. You cannot install custom recovery without unlocked bootloader. For the safety of your device, I'd suggest sticking with XDA, and not Googling random websites. That website obviously has incorrect information.

AT&T isn't going to "OTA" you by force. You have to accept the download, then accept the installation. Cancelling either of those will prevent the OTA from being installed.
If you want to update to the stock 2.20 firmware without running the OTA or RUU (and therefore keep the ability to flash kernels and radios), than yes, the ROM you linked is the method I would suggest. But you would need to unlock the bootloader, then install TWRP before you can flash the rooted 2.20. Also keep in mind there are newer (than 2.20) firmwares already posted in Development (2.23, 2.29, etc.) in similar pre-rooted form. Not to mention custom ROMs based on 2.20 or newer.

SuperCID survives OTA. But the 2.20 OTA has a new hboot, which fixes the hole by which kernels and radios can be flashed from recovery, so my recommendation would be not to install the OTA.

Ok, that is VERY good to hear.
BTW, thank you very much. I read somewhere that ATT could/might force the OTA, and I've been worried about losing root ever since, but not quite ready to (presumably) completely void my warranty with a bootloader unlock.

I think bypassing the user acceptance dialogues for the OTA install would be a violation of how Android fundamentally works. It would be a serious security issue, as it might allow rogue software to be installed on your device without your interaction. I seriously doubt AT&T would institute such a thing.
The user confirmation of the OTA might be a liability thing, too. If the performance of the device is adversely affected by the OTA (happens to some people) and the OTA was forced by AT&T without the owner having a choice, it would seem to me that AT&T has to accept the responsibility. People can claim its AT&T's fault, and demand a replacement device (since AT&T technically installed the software remotely). By making you confirm the OTA installation (and giving you the chance to opt out), you pretty much are volunteering to install the software and accept the consequences.
In theory, unlocking the bootloader voids you warranty. But more than a few folks on here have gotten warranty replacements from AT&T (after unlocking the bootloader), without issue. Sometimes in-store (within the first 30 days) without them even checking for the bootloader unlock. No guarantee that this will always be the case. But just throwing it out there. Its still up to you whether unlocking the BL is worth the risk in your own case.

I dont remember but isnt hoxl supported by goomanager? As long as your rooted you can install a recovery from it with a locked bootloader. I always reccomend unlocking but im pretty sure its not a total necessity to get twrp recovery

The hoxl is officially supported by twrp and can be downloaded from goomanager. I do not know if you can install a custom recovery without an unlocked bootloader. I would be interested to know if this can be done as well.
Sent from my Nocturnalized One XL using Forum Runner

when you try to push a recovery via fastboot with a locked bootloader it will fail due to invalid signature I don't see how goomanager would be any different.

Is there any harm in trying it?
If I install "goo manager", and let it do its thing, and the locked bootloader prevents it from doing so, there wont be any other side effects, will there?
If I come off as a complete noob at this - its because I am..
This is my first Android phone, and I *really* want to avoid bricking it, so I want to make sure I understand as much as possible before I go
trying to do anything to it.
Also I'm still wary of unlocking, mainly because of the whole "will erase your phone" bit.
I'm not yet fully comfortable that I know how/what to fully backup all of "my" data on the phone so as to facilitate easily putting it all back.

I'll answer some q's here.
1.) you cannot flash a custom recovery from hboot with a locked bootloader
2.) you CAN dd a custom recovery with a locked bootloader. However your device will be soft-bricked.
3.) you CAN install custom ROM's via dd right from android. This is how we did it back "in the day".
4.) you "might" be able to get away with dd'ing a custom kernel with locked BL, not not sure. In fact, I'd bet it will softbrick now that I think about it.
Anyways, the SAFEST way to do it is via unlocking the bootloader and installing your roms from custom recovery.

Hey folks. It's me again :victory: So I've got another super easy video guide on how to root your shiny new Samsung Galaxy S4 I337 or I337m.
This guide is using djrbliss's Motochopper tool. This tool has made it easier than ever to root a device! So BIG thanks goes out to him!

Just sold my Rogers S2 LTE because I upgraded to the S4. My quick question, if I ROOT and retain the original Samsung Recovery will I be able to still get and do official firmware upgrades? This is the only thing stopping me from going forward with rooting.

You can still get updates, but you will loose your root access with each update.

Hey, how did you sim unlock it for free, do you mind sharing?

yeah sure!
similar method worked for my GS III; havent tested the GS IV with different sim just yet but GF's old GS III is working just fine for her sister in Canada (Bell i think). GF found it actually, and did it to hers 1st. ill know if it works when we leave for work in Montreal next week or if i bum a t-mobile cell from a friend.

WRONG, I am unable to update my device, it says that my phone has been modified, and yes, I have rooted it with this video.

Whenever I try this method, when it goes to push the exploit, it says error multiple devices or something. when I only have the S4 plugged in. Followed step by step.

Safe to root?
Excuse my ignorance, but on another thread it was suggested that in the absence of recovery and a backup image rooting might be premature. Is the general consensus now that it is safe to root? There seems to be some backup images around thought I don't know if they have been tested, and I haven't heard about recovery.

Newbie here... couple of questions
I have the same concern as the member above... is it already possible to restore the phone if something goes bad? Is there instructions anywhere around this forum? where?
Also, once you root the phone you can proceed to download a ROM and install it... when a new ROM version is available and I download and install it, do I lose the root?
What is the best (if more than one is already available) for the ATT S4?
Thank you all and sorry for the "newbieness"....

No, rooting gives you certain superuser privileges. You can use Titanium Backup to freeze and restore bloatware, AdBlock to block advertisements, etc. Some phone tracking software and remote desktop control software requires root as well.
You cannot modify the basic operating system (ROM) until the bootloader is unlocked. You can overwrite the files, but that will brick your device since the bootloader checks signatures.
There is a bootloader exploit for the ATT S4 that will be released within the next week. The developer was waiting until the Verizon version of the S4 was available so more people would be able to use the exploit before it was patched.
Do not accept an OTA update for your device as that is how they will patch the bootloader exploit.
1. Root your device.
2. Carrier unlock your device.
3. Install custom ROM when bootloader is exploited later this week.

Cool, thanks for the reply. I was under the impression that the bootloader was already exploited. Pure BS those protections that always end up broken like the IOS ones. What I would like is to have the S4 as factory released and load a good ROM without any problems and no bloatware. If not for the warranty I would buy an unlocked phone elsewhere.
Well, let's wait for the exploit next week. I don't want to brick my phone and not able to restore it. I will keep checking back.
Cheers and thanks again

Regarding the bold above, I am honestly not that interested in the Custom ROMS right now, only rooting and with this method it does not install any custom recovery, right? As well, if I root via this method will I be able to still do the OTA updates since Samsung recovery is untouched? I know and understand that I will likely loose root, but I can always re-root, right?
I am itching to root and this is the only thing stopping me as there seems to be much confusion about this.
BTW I am on Rogers (Canada) i337M if it makes a difference

I've been a bit confused as well despite reading hundreds of posts and watching referenced videos (I've also been hesitant to ask questions given the culture of this board). Here is what I hope is accurate, please correct where I am wrong:
We can root I337 now.
Doing a simple root now is reversible, ie, can be un-rooted.
The bootloader unlock is needed primarily for custom roms.
If one does not desire a custom rom, there is no reason to wait to root.
And, a few questions:
Does rooting wipe out apps, settings, and/or data?
Will an AT&T android system update remove the root?
If so, can we just root again?
Thank you for clarifications. I'm sure there are many that are not posting with some of these questions. I will be glad to put together a noobie's guide if I can get a handle on all of this. It is all out there somewhere, but very fragmented, and often one post is contradicted by another.

Your assumptions are correct:
1. Yep.
2. Yes, you can delete busybox and su in your system directory to get your phone switch your phone from "Custom" to "Official" status. If you install SuperSu and remove Superuser you can have root while keeping "Official" status.
3. Correct.
4. If you **** up while messing around with root you can recover to stock ROM via Odin or Kies. There is no reason to wait for root.
To answer your questions.
1. No, nothing changes. You just enable superuser privileges.
2. Typically yes. Don't accept OTA's until your know they're safe.
3. It depends if they patch the exploit or not.

[Q] What part of the software depends on rooting?

So I just got my HTC One M8 last week. After seeing how terrible HTC Sense is, I decided I want to root and then flash CM. I rooted my last phone, the Samsung Galaxy S3, but this seems a little bit harder. I've looked at a few guides, but I'm afraid that there is a certain piece of software that depends if the root will work or not. On my S3 I just had to see what Android version I was using, but this phone has a few different types of software. Which one do I pay attention to? Android version, HTC sense version, software number, PRI, PRL, ERI... Also, when I rooted my S3 and then wanted to flash a rom onto it, I had to reset the flash counter because I was on Verizon. Does it work that way with this phone too? Anyway, what part of the software listed depends on if I can root the phone or not? Is it just Android version, like usual, or are the two pieces I need. And if so, can someone link a guide that works with my current software? I'd really appreciate it.

My understanding is that the Verizon m8 has only had one update. The root exploit (weak sauce) and S-off exploit (Firewater) each work on either firmware versions. Rooting via weak sauce may be enough for you depending on your need to customize your phone.

http://forum.xda-developers.com/showthread.php?t=2708628 follow this thread completely.. depending on what you wanna do with your phone you can s-off and unlock the boot loader to flash a custom recovery and roms. Or just weaksauce root to get temporary root. Which is just a simple apk download you install.

Sweet thanks for the link now is there an RUU method or in other words, returning the phone to complete factory stock?

Familiarize yourself with Odin. It's a PC program used to flash things like the stock tar file, which is similar to HTC's ruu.

Alright thanks you I should have enough information now to root my phone and restore it back in case I want to restore it back to normal. Now does the bootloader need to be unlocked and do Galaxys have the S-Off option. (I came from an HTC phone which is why I am using HTC terms lol. This is also my first Galaxy Phone)

I've had HTC phones before as well, so I totally understand. There is no s-off needed. The only locked bootloaders are on Verizon and AT&T. The only concern on samsung phones is tripping the Knox counter, which only affects warranty claims (and not always).

Warranty with T-Mobile

So I have received a "Certified Pre-Owned" Nexus 5 from T-Mobile just a couple days ago. Within the first few hours, I rooted it. At this point I could no longer install (but still received) OTAs, and IIRC that is because the system partition has been altered. I eventually did unroot, but I still could not install OTAs. Now, there is a hardware issue with the phone: it will not vibrate properly anymore. And I have tried those solutions like pressing on the back. So will need to return this phone for a replacement or repair. I have read somewhere that T-Mobile runs a diagnostic tool to check the phone software. My phone is not rooted, and I have not unlocked it or altered the ROM in any way, but will T-Mobile know that my system partition is different? Am I still covered under warranty?

You could just flash the latest entire factory image and relock the bootloader - not sure how Tmobile would be able to tell anything different especially since the nexus 5 isn't a carrier locked device.

I don't plan to unlock my bootloader at all for a while. I unrooted with KingRoot, and now my phone is identical to stock except for a couple of files in the system partition that are traces of the root. I know this because OTA installations will result in an error. But that is the only thing that differs from a stock device. Will T-Mobile be able to access the system partition or somehow force an OTA upon it and find that it was once rooted? This is what I fear. What exactly does T-Mobile do when it receives the phone to make sure it had warranty?

Actually, what I would like to know for my peace of mind is...
Is there any way that T-Mobile can find out that I rooted?

I used the Nexus Root Toolkit to unlock, flash stock, unroot, lock, set tamper to false, etc. I can install OTAs now, and there is no way that I can think that my phone can be seen as altered. Just to confirm:
Is there any way now that T-Mobile will know that I did anything?
