[Completed] Can't root Galaxy Tab S2 SM-T810 on 5.1.1 - XDA Assist

Is there somewhere that has a working guide on how to reliably root a brand new Galaxy Tab S2 SM-T810 on 5.1.1?
About a month ago I bought an S2 tablet (9.7", Wifi) and immediately set about rooting it using xda-developers.com. Many years ago I rooted a couple HTC phones because I was having terrible battery performance but never found the need to do the same on my S3 or S5 phones, so I'm a little out of date on the tools and processes. Apparently jumping back in at 5.1.1 was poor timing. I spent half the day using the information in this forum and what else I could piece together to try and get the root to work but eventually got frustrated and stopped. I spent several more hours trying to jump back in at the same place and have been unable to get this to work. I don't have the windows open from all the places I've been, but I've seen a lot of people seeming to report they're having difficulties as well, but that's when the thread just stops and I can't tell if they found some magic to help them out or where I'm struggling.
This website has grown considerably since the last time I was trying to use it as a resource, and I'm either searching for the wrong things or am making mistakes out of frustration. My route has seemed circular, to paraphrase: I don't remember what or how many bootloaders I've tried, my device won't root. I tried using Odin to instead load TWRP, but it also won't install that. I've seen the suggestion to downgrade to 5.0.2 and using a different set of tools, I can work my way to rooted and back to whatever ROMs I want, but then I see conflicting information that I can't just downgrade to 5.0.2, don't see an obvious location of a ROM to even do that with. I don't even know if I'm looking in the right area of the forums.

Hi,
Please check this thread: http://forum.xda-developers.com/tab-s2/general/guide-root-tab-s2-t3205019

[Q] AT&T Note II Won't Read SIM After Rooting+Android Rev. HD

Hi, All--
I've been scouring the web for almost 24 hours before asking this question (because I know how much forum-regulars hate duplicate posts that have already been addressed), but I can't seem to find anything specific to my case.
I rooted my AT&T Note II using CWD and flashed Android Revolution HD. Everything worked fine. The ROM is sleek and elegant and packed with functionality. Unfortunately, my phone no longer recognizes the SIM card. At no point have I been able to make a phone call or send a text message since the phone has been rooted. In addition, it seems to shut down randomly. It may be worth mentioning that I rooted the phone using a Mac, but I don't think that affected too much.
Since then, I've been looking to possibly wipe the phone, re-root the phone, or un-root the phone and install AT&T's stock firmware (which seems to not exist yet), but none of these options have worked particularly well. I even wiped the phone then attempted to flash a different ROM (I tried Paranoid Android) but was greeted with multiple "Installation Aborted" messages in CWM.
This http://www.andromods.com/unroot-locking/how-to-restore-samsung-galaxy-note-2-to-stock-rom-firmware-with-odin.html went online yesterday and purports access to stock AT&T firmware for the Note II. Unfortunately, I can't confirm this because I can't run Odin on my Mac.
I found this http://forum.xda-developers.com/showthread.php?t=1992303&highlight=wipe here on the forums, which seems like a promising way to unroot an AT&T Note II, but when I tried to run TWRP, I kept getting "Installation Aborted" messages as well.
Can anyone help?
Thanks, mods, for moving my thread to the appropriate forum.
Is bumping a thread considered rude here? If so, please forgive my impatience--I've never used an Android phone before a few days ago, and I'm kind of thrilled to finally get to play with my phone.

[Q] 4.4.2 Finally Rooted, Unlocked, Flashed Recovery, and Cyanogenmod installed

Alright so let me start off by saying that I have never had so much hell rooting and putting a custom Rom onto a phone. I am also a bit disappointed in xda as non of the articles were of much help, they were all broken up and I ran into trouble at literally every step. The easiest part was rooting the phone with ioroot, but finding it actually wasn't that easy because most of the tutorials I found from the start kept having me use other methods and none of them worked.
Second once I performed this step and had everything installed I realized that in order to use my wifi hotspot, I was going to need a custom rom. this was of course after trying dozens of worthless hotspot apps in the store, none of which worked. So I started trying to put a custom recovery on the phone, this was by far the hardest part, I tried and scoured the internet for 3 days, I swear to god I read every article and tried every method out there....the new ATT LG G2's however have a lock on the recovery to prevent people from doing this, I found it strange that none of these articles written based on 4.4.2 thought to mention that an exploit has not yet been found. Finally I ran across an article where I learned of this and was told to downgrade, so I downloaded SuperSport & big fau LG G2 D800 Flash stock. Thinking that this rom was going to unlock the recovery because it said it would, I ran through the process.
This however, was not the case and it didn't help, the whole time I was convinced that this had unlocked my recovery, I continued to try every tutorial on installing a recovery onto this device, the AT&T LG G2 kitkat 4.4.2 (D80020c), which btw is a week old from the date of this post. I like a lot of other people, will have this phone and be looking to unlock, root, install custom recovery, and install custom rom. For this I would like to figure out a few things and hopefully if y'all help me figure this out, I can include fixes for it in the next article that I write, which will explain how I successfully put a custom rom on my AT&T from start to finish. I will also include in this article what could go wrong and how to fix it, too many articles are written without taking into consideration the possibilities of what could go wrong.
It took me three solid days of scouring the internet to get a custom Rom on my phone, running through problems at every step I still have a few questions. After downgrading from 4.4.2 to 4.2.2 my recovery was broke, thankfully I was able to fix this using flashify in the app store. I then installed Cyanogen Mod 10 (cm-10.2.0-d802.zip). and installed it through recovery, when I rebooted I was presented with a fastboot which would do crap when I would plug the usb into my computer...I never figured out what the problem was for this, but I ended up trying a version of CM 10 which was released for the LG G2 D80010d that I downgraded too, the tethering doesn't work...no big deal, but the problem is when I set WiFi hotspot up and connect, on my computer I get SSL error's, my computer completely refuses to let my connect to facebook or google, saying that the connection is insecure, it won't let me grab any kind of certificate and I can't find a solution online. I have tried rebooting both the computer and phone, I don't get these errors on the WiFi at the gas station.
In the above paragraph, I stated the two problems I couldn't really figure out, I haven't tried to install any other custom roms, but I will try that today, I have to save my bandwidth on my phone so I will walk down to the truck stop and download one, ps I had to flash my phone back to stock about 5 times before I finally figured out I needed to downgrade it, then I had to do it 2 more times.
If y'all take the time to read this and help me, then I will take the time to write a new and working article describing how to do it from start to finish and it will be written with explicit detail on every problem I came across and how I fixed it.
Figured out how to mix the firmware
Alright, so I was reading through a few more articles and I ran across this link, which will allow you to upgrade back to D80020c, but without loosing the stock recovery. I'm going to have to wait till later today to give it a try though, because the internet at the truck stop is to slow to download something of that size.

well first I want to clarify you on that week old part especially since we have had kitkat on d800 since about feb 27 in fact if you look at garys thread about kk with custom recovery which is originally from march 6(on 5th we figured out what needed to be done but on 6th they began rolling out) and also if you would have asked for assistance I could have helped to find all needed info on rooting and everything (I just don't spend a lot of time in the dedicated d800 thread) anyways as for 20c I've been on it since root was available(also on first day of release of 20c) and have been running garys rom since it was released and I love it but if you want tethering(I know a way to enable you just need a paid app) and there are already threads on doing things from start to finish http://forum.xda-developers.com/showthread.php?t=2633150

Sorry, I didn't mean to sound like a ****. I just had a really hard time finding a complete walkthrough on this, I ended up taking bits and pieces from different tutorials and it seemed that most of them only covered one aspect of the process, like recovery, or if they covered the whole walkthrough they would either leave something out or I would recieve errors, such as the loki error, and the original adb not detecting my device. I had to download an adb from an alternative source because the official adb wouldn't detect my device, after trying everything but it didn't bother me because I figured it out and thanks for your response, really appreciated, I will check that out....How many mods have you tried and what features do you like about them? I liked the ideal of the CM 11 for the 4.4.2 because it boasted the porting of pretty much every feature that comes on the LG G2 4.4.2...Like the double tap to unlock and such....I will check out Gary's mod and see what it offers, thanks again
I would just like to start out by saying congrats on getting your device to where you've wanted it - I do agree that the G2 is a special case right now considering the lack of development and spotty information available for development.
With that being said...
There is a really good reason why the site was named XDA-"Developers" and not XDA-"Newbs". The primary focus of these forums is for the purpose of developers engaging one another and sharing their discoveries with the community. There are some really great developers here that take a LOT of their own PERSONAL time to create the stunning softwares, hacks, themes, etc. that often ultimately get freely distributed to the public. Take note that 99% of these threads start off with "Use my software and instructions with NO expectation of support or warranty" or "Flash at your own risk".
These folks give so much to the community and often ask for little or nothing in return. While the information right now is pretty sparse and scattered, do you think you could have achieved what you did without it? The mere fact that you have a custom ROM, root and recovery is a testament to the hard work of the folks here who are giving their own time up in the name of furthering development. Our G2s, while stellar devices, are the outliers in the world right now because they are not in the hands of the masses. How many people have looked at you and asked "is that the new Galaxy??" I believe in time, someone with way more time and Android know-how than I, will deliver something mind-blowing to the XDA community for this device. Just be patient and realize that the majority of Smartphone users right now have a GNote, S4, or HTC something-or-another.
Finally, re-read your post and try to hear the tone you delivered. You sound upset that the XDA community hasn't delivered you an easy root/recovery package on a silver platter with all the trimmings. Again - this forum is for developers. What they choose to share with the rest of us as non-developers is totally up to them. They also tend to share more when the support they receive is positive. Long rants about your disappointment in the community over how you had a hard time getting what you wanted on your device - well you catch more flies with honey...
Cliffs notes? Hug a developer, and say thank you for what you've managed to accomplish with your device. Without the info posted around here, we'd all be living with stock ROMs and unrooted, bland G2s. If you are unhappy with your own personal experiences with getting to where you are right now... Well, you obviously know where the "new post" button is. Become a contributor, tell us how YOU did it and give back to the community. If you only rant about your disappointments, then you aren't really making anything better for anyone around here - in fact it only serves to clutter up an already fragmented knowledge base.
From one long winded poster to another - good luck in your ventures with the G2. It has served me well so far and I believe it will continue to do so for quite a while.

tethering
If tethering is all you wanted. I would have done it the easy way. You can unlock WiFi tether by trying to turn it on, then when it fails use sqlite editor from the market to go in and change the provisioning status to 0 in the database file. Sqlite costs 2 bucks, it would be worth that to not have to go through all that. I never thought I would own a phone without a custom Rom, but so far I'm still stock on the lg g2 it's that good. Most annoyances can be fixed as long you have root.

[Completed] Samsung S4 SCH-R970 (Us Cellular) ...No easy way to root? also want CM 11 0r 12

Hey everybody, I have literally spent all day on this computer looking for a way to flash Cyanogenmod. I am currently running version 5.0.1 which I do not like at all. Having slow email problems and occational black screens right after this last update.
I do not know much about the process but I did successfully flash CM on one of my older phones a couple years back.
My google searches might come back with a couple rooting guides but then most end up being for older versions. Or maybe not for my particular model #. I have tried KingoRoot and Towelroot today, but both froze somewhere during the process. Luckily it wasn't far enough into the rooting process to do any damage. I tried OneClickRoot and paid for it,(mistake), but then was told it had to be done remotely by them. Not very fond of that idea. I even was in chat with their support and thought we were ready to start, but he asked if I could come back 2 hours later because all their techs were in scheduled roots.
I just want to find a quick easy and safe way to root this model and version of lollipop, myself, which isn't easy to find. I'm sure I can handle finding and flashing Cyanogenmod myself.
Can anybody help point me in the right direction?
Thx. Jerry

All I see in the Samsung S4 categories are " Galaxy S4 (International Exynos – Snapdragon | Verizon | Sprint | AT&T | T-Mobile | Canadian)".
I have a US Cellular. I realize that may not be one of the biggest carriers, but would USC be supported under one of these other carriers?

I did already post in that forum, anonymously, last week with no response. I have had this forum bookmarked for about two years but only posted once. Couldn't remember my password at the time.
I have done numerous google searches with no results that would work for my model #, carrier, and android version. 5.0.1 The version seems to be the sticking point. Maybe I just need to give it time for that combination to show more results with google.
If I was to get another phone, what would be the best phone/carrier out there that would respond the best to rooting and custom ROM's?

NOOB Questions Samsung SM-G900A

Hello,
I have been looking one source of solid information in this phone but seems to have too many conflicting opinions.
I have not rooted a phone before, but I'm comfortable following directions and taking things step by step. I have built many PCs, repaired laptops, installed OSs, even some analog cable and satellite "testing" in the past.
I have Nougat on my tablet and it looks pretty cool so far. I was wondering if I can root/mod and load Nougat on my phone. It seems that many places say YES, the Galaxy S5 can get Nougat. Only to find a note somewhere in the instructions that the SM-G900A is not supported, just about every other one is.
So......
Can I root this phone?
Can I put Nougat on it?
Is there really any benefit to doing either or would I just be wasting my time.
Can I go back to the stock AT&T software if I have issues?
If I do that will it go back to the ORIGINAL OS that was on it or back to the current version of Marshmallow that I have on it now?
Thanks, any suggestions are welcome.
Matt.

Newbie looking for help on rooting an old Galaxy Tab 2 10.1 SGH-I1497 (AT&T)

Hello to you all and thanks in advance for your patience... for most of you this may be "stupid" but I have so many doubts and I don't want to end up with a "Samsung Brick" on my hands.
1.- Device: Galaxy Tab 2 10.1 SGH-I497 (AT&T) running Android 4.1.2 Base Band I497UCMF3 Build JZO54K.I497UCBMF3
2.- Background: Bought it new from AT&T and had it with wireless service with them for 3 years... ended the wireless service and kept using it as a WiFi only device. while it was still under contract it updated firmware a couple of times till it got to 4.1.2 since then when you check for updates always tells me "Current Software is up to date" that has been for the last 2 years pretty much.
Needles to say it keep running slower and slower at time passes by and newer versions of apps don't run as it should. Of course I have the "infamous" AT&T pre-loaded apps that I don need in it.
SEPARATE ISSUE: For sometime now it's working fine, then it tries to load something and stay like "buffering" and nothing goes forward... I found that have to manually disconnect from the WiFi and connect again and it starts working again. Rest of ten devices at home (Phones, Tablets, Playstaion, etc...) don't have problems.
3.- I have heard for years now about rooting and the PRO's and CON's of it... after some reading I feel that if done correctly that is my better choice to give some new and better life to my "entertainment pal" but same reading confuses a bit out of me between options and which ones works which one doesn't and which one is the right for me.
4.- I have found here this: https://www.xda-developers.com/root-and-recovery-for-the-samsung-galaxy-tab-2-10-1/ that then takes me to this original thread https://forum.xda-developers.com/showthread.php?t=1657056
Is this still the right way for me ??? I never updated (or used) via KIES it was always on wifi.
Any pointers suggestions and "Dumb and Dumber" step by step guide will be really appreciated.
Regards
Pato69mx
