Please note I don't own this device and spend a lot of my free time bringing these builds for you to use and benefit from.
FEEDBACK IS APPRECIATED.
THANKS.
DONATE ME HERE IF YOU WANT TO BUY ME A BEER OR HIT THE THANKS BUTTON IF I HELPED YOU
.

NOTE ON ROOTING WITH TWRP:
If you have kingroot installed remove this before rooting with SuperSU above or you will have issues.
Kingroot attempts to block Supersu so must be removed first by using the uninstaller in the Kingroot superuser app.

Absolutely NO feedback
Out of literally hundreds of people that have downloaded and benefitted from the files I've posted NOT ONE person has left ANY feedback whatsoever and only 5 have hit the thanks button and 2 very generous people have offered donations to whom I am very thankful.
As developers we need encouragement and ALL we ask is a quick click on the thanks button and a little feedback.
It's not too much to ask is it for hours of work on a device we don't even own?
XDA is a 2 way community, it's GIVE and TAKE not just TAKE.
Due to this I have decided I am not going to update the builds to the new TWRP v3.0.0-0.
Thank you.

Come on people. It is not asking to much to thank someone for giving us what we need to make our tablets much better. Over in the T-Mobile S6 thread we have the same issues. These devs do this for us in their spare time for free, so showing a little appreciation is not asking a lot.

Hi, sorry for the late reaction. I succesfully installed your custom recovery but than i had trouble with SD card, it wouldn't get locked in the slot so i couldn't try the backup and restore funtions.
Now SD problem is fixed but when i boot into recovery i get stock, TWRP is gone so first chance i get i'll try to flash it again (don't have a PC available right now).
It would be a shame if you would stop working on our device, you gave us a very important tool for witch i would like to thank you.

You don't need a pc. Extract the recovery.img from the .tar file and then flash with flashify.

I've not rooted yet and i'd like to have a backup before i do, so i guess i'll just wait a bit and flash with Odin.

I want to thank @ashyx for getting Root &TWRP for the Tab E. I bought my SM-T560NU one week ago today. The first thing I did when I got home was to search for Root & Recovery and I found this thread. Everything flashed fine for me. Without devs like @ashyx on XDA we would be stuck with ordinary Tablets & Phones. So make sure to hit the thanks button and post feedback to let them know if things are working or not. It's not that hard to do.

+1, I haven't tried it yet on my wife's SM-T560NU 'coz my wife always have the tablet with her. She wouldn't even let me get close to it since I screwed up her phone. I will report ASAP when I get a chance to steal the tablet and root it (hopefully successful).
Thanks to @ashyx in advance and to guys reporting back on their experience. Please keep the thread alive.

Thanks for the feedback guys.

Smt560nu rom
Was anyone able to find the stock ROM for SM-T560NU on SAMMOBILE?
** EDIT ** I've tried two different computers, reinstalling samsung drivers and different ports. Can't seem to get past the setup connection step in ODIN. Does anyone have any suggestions?
** EDIT 2** Got it working! Thanks ashyx!

Hello! I have just finished reading through this thread and wanted to say thank you for all your hard work and dedication ashyx and the testers! I am about to purchase this tablet and wanted to know if model number SM-T560NZKUXAR is compatible with the files you created?

Are you attempting to flash the stock rom with twrp? As far as Im aware there is no custom rom for this device?

I apologize for the stupid question here, but if I am just wanting to do root do i have to flash twrp_2.8.7.0_sm-t560nu.tar first? Or can I just flash the root file

If you're talking about this http://forum.xda-developers.com/showthread.php?t=3300291
Then you don't need to install twrp.
However installing custom recovery and making a backup is one of the best mods you can do to your device.

When I got my Sm-t560nu last week the first thing I did was flash the TWRP 2.8.7.0 tar in ODIN, then I flashed the chainfire su file in ODIN to root it and everything went fine for me. After that I made a backup just like @ashyx suggested.

Ok thank you so much for all your help!! I did the root part successfully which is what I wanted. I don't understand the purpose of doing the twrp

Locked peloader for one, no flashing via SPFT. I heard someone say to get to stock recovery you need to use the button combination same as Samsung phones. Volume up + home button + power. Try this and let me know if it works.
To unlock bootloader, use fastboot to do so. Do some research before unlocking. I made a custom recovery for this device but I couldn't test it.

Care to share said custom recovery? might help get it tested if people could get hands on it.
would also help if you shared what tools would be needed to flash it, and what tools are needed to back up beforehand,
possibly even a small step by step guide like you did for the other alcatel phones?

The recovery.img I compiled was a bit lacking, I'll have to fix build and probably make a guide, if I do have time that it.

Yea, I have been trying to root this phone for a while. I have probably tried everything besides Saferoot and nothing has worked.

Hi AdamOutler,
Beginners Clarification: your post 15th October 2016, 05:51 AM |#6 "Lol! Flash with Odin on Windows, Linux and Mac. Use JOdin3," Googled and found your "[Release] JOdin3 CASUAL Cross Platform and Web-Based Flashing For Samsung Phones" http://forum.xda-developers.com/showthread.php?t=2598203
Does this mean you were able to root the Alcatel OneTouch A462C using JOdin3? (Also please do no Flame as had wanted to ask this by PM but was unable)
Thanks
Ken

I know this is a pretty big bump but I to need help with this phone any updates?
This Phone is a Qualcom Technologies, Inc "Proccessor MSM8609" Model TCL A462C Acatel Onetouch runing Android version 4.4.4 and Yes I have tried King root It reports Rooted but only temporarly and I cant even remove system apps with the temp root and yes I have tried third party apps for this process they claim root granted and even claimed they removed said apps but as soon as reboot root is gone and the apps are back please help.
Further more I havent been able to find a reliable way to transfer my root over to super su eaither
By the way I can go into factory recovery but cannot go into fastboot or download mode the only other mod I can go into is Safemode.
Also It Takes A while of running with the temp root but eventually although it takes a while kingroot will also eventually tell me that this phone restricts root authorization and by the time this happens Apps also start reporting that the su binary is not installed with the exception of super su which tells me su binary ocuipied This happens later after those same apps previously told me root granted. And yes I have checked and made sure there is not kingroot imposed restrictions. I dont know why this happens.

Setting phone back to defaults for dummies

It doesn't appear anybody knows what to do with this http://forum.xda-developers.com/general/xda-assist/incoming-calls-answered-vener-make-to-t3500914 and I now have to go back to full factory stuff with no custom recovery and stock os to find out if this is a hardware issue. I did a TWRP restore from several months ago when the phone worked fine and it still has the incoming call issue from the link above. Did a factory wipe in Teamwin, same thing.

Please pretend than I am a not particularly precocious ten year old who needs to make this phone as if I just took it outta the box. I have searched here and around the web. All I find elsewhere are paid download sites or 3 hour downloads and here I can't make heads nor tails out of the volumes of impressive information in these forums.
I do have PC skills, and this is my first smart phone and getting it rooted and the recovery installed and all that wasn't too tough back when I got it 15 months ago. It appears restoring it back to stock is quite a bit tougher.
I have to see if incoming calls still don't work when the machine is totally stock. Is there a way to do this without a 3 hour download and a masters in computer science? I sure would be most grateful for any help with this.
Thank you.

You can simply do "Rescue firmware" via Smart Switch.

Thank you sir! I will have a look at this a bit later tonight when possible.

This won't work with Teamwin recovery right?

I have none of the boot options in this video. Not that I don't appreciate it.

I have none of the boot options in this video (TeamWin). I also have totally different options in SmartSwitch. Not that I don't appreciate it. It doesn't have an option to search like the video says and already has an upgrade in there. I deleted my google accounts like it said and now I have this:

You won't do anything on TeamWin.
1. Open Smart Switch on PC.
2. Turn Off the phone. Press Volume down (not up) & Home button & power button. When you see the warning screen, just press volume up once. If you see "Downloading" screen, plug into PC
3. Do "Rescue Firmware" via Smart Switch.
Thats it.

Well they had to write that, because if something happens during flashing it is not their fault, and you have been warned.
You can also uninstal supersu, and download that same fw Smart Switch would install from another internet source, and it will probably be a painfully slow download, but that is up to you.
I cannot guaratee you that Smart Switch emergency initialization would solve your phone issues, but it is the way to unroot and for the phone to become officially stock, offcourse knox will stay tripped if it was tripped during rooting (and probably is, unless you are on 5.0.2. and were using ping pong root).
I used Smart Switch emergency a lot, and it was always succesfull, just follow instructions, connect your phone in dowload mode when it asks for it, and there should be no problems getting to stock.
...I saw just now, in your other topic that you have fixed it /thumbs up!

Bricked MT6577 SoSoon/Senq X8 Elite 3, NO USB Debug/ADB, Stock Recovry No Roms to D/L

I've had an MT6577 phone sitting around for a few years now that's been stuck in a boot loop. My phone karked it today and this is the only device lying around, hoping it can be revived some how to save a few dollars.
It all happened one time when I tried to use an app to install a new font just to see what it looks like.
Seems to be the most obscure thing ever made as it has many names and models all with 0 firmware available. Typically SoSoon X8 Elite 3 shows up as the most common make but I recall the original box having Senq X8 Elite on it.
The bad?:
USB Debugging is almost certainly off because ADB can't find a device no matter if I just plug it in off, in bootloop (shows 2 drives on my PC that are not ready to be used in this stage), fastboot mode, recovery (install update from ADB)
Questionable root, one of those generic one click apps.
No stock or custom roms available any where that I have found from searches here and there over the last few years
I tried to follow a tutorial to port an MT6577 rom but I would need the kernel off the phone, which can't be done to my limited knowledge.
No custom recoveries available, running Android System Recovery 3e. Can't use TWRP MTK 1 click install on my PC because the device needs to be fully booted to work.
The good?:
Fastboot seems to work as it does show the device in the command prompt "fastboot devices"
I think the bootloader was unlocked at some point, no idea on the relevance of that.
Any information on if/how to sort it out is greatly appreciated.
Last ditch effort to try revive it because it was decently usable for what it is, hoping that someone on here has one lying around somewhere.
Will add more information as I remember and reply to any responses asap
Thanks for your time

Also tried "getvar all" which according to a post on a xiaomi forum, is an MTK specific command, returned nothing anyway.
Just showed the "..." until I pulled the USB cable out.
Thanks for the suggestion, guess that's a pretty significant strike against any kind of fix for it.

The battery is soldered in but the back panel pops off easily, no information at all besides "X8" written on the battery.
I've found what I'm sure is the exact same model phone on GearBest and I've asked the seller if there's a chance of them providing the stock firmware.
This is the only form of model number I've found, but it's generic and shows up more Sony Xperia posts than anything else through google.

You don't need a whole firmware, all you need is a good copy of system.img from a device like yours or from a similar device that uses the same kernel, trying to find a whole firmware that will flash without issues will be kinda difficult because there are things in a whole firmware that might not work on your device, a system.img on the other hand doesnt have all the extras in a firmware that could cause issues. Use fastboot to flash the .img with this command.
fasboot flash system system.img
From what you described causing the issue, technically, all you "need" is a copy of the stock font to replace the font that you tried and screwed it up with, but getting just the font back on without doing anything else isn't as easy as flashing the whole system.img unless you have TWRP or can sideload apps in the recovery that you have.

Thank you for finding this, much closer than anything I've ever found. From what I can see on it, it's really close spec wise. I'll download it and have a look through the files before trying it.

I did try that. I have all kinds of zips that could supposedly be flashed with the stock roboto font as well as the file itself ofcourse but I could never get fast boot to so anything with it. Based solely off the assumption that all android devices use it as the default, and assuming that the app was just renaming custom fonts to Roboto or something along those lines.

Basically, every time I try to flash anything other than a stock ROM the flash fails and i get "Only official released binaries are allowed to be flashed(RECOVERY)" on my phone's Download screen. (Here's an pic of Odin when the flash fails)
I've tried flashing the latest carrier-unlocked stock ROM to it, and using the phone for 2 week without rebooting (was constantly connected to the internet, uptime was around 300 hours before i attempted to flash TWRP again). I've also tried some solutions I've found on the XDA forums (like flashing the nougat bootloader to my phone, and changing back the time by a month) but nothing appears to work.
I also got the phone used if that's any useful info.
The "OEM Unlock" option was also enabled for some reason after enabling Developer Options. And i also made the mistake of resetting the phone via the recovery menu since i didn't know the previous owner's Samsung account password to remove it from the phone (I'm guessing that's the thing that initially triggered it?)
The phone is also from Spain (but i flashed a stock ROM from my country so it should be fine?) and i have a SIM inserted into it if it's relevant.
I also very much don't care if KNOX trips or not. I don't plan on using any Samsung-made apps ever again since I wanna install a FOSS (free and open-source) ROM to my phone and I don't plan to *ever* sell this phone either.
HUGE thank yous to anyone who finds a solution

Can you send a screenshot of the bootloader screen?

I'm guessing you mean the Download screen..?
Here's the Download screen if so:

You did run fastboot OEM unlock?
or
fastboot flashing unlock

I don't think my phone even has fastboot
I tried booting it into recovery and selecting to apply an update with ADB, I've also tried it at the "Waiting for update" screen.
Fastboot just gets stuck saying < waiting for any device >
The OEM unlock checkbox is already checked in Developer Options.
I don't think the S8+ needs another way to enable OEM unlock other than the checkbox in Developer Options.
EDIT: Here's the output of adb logcat --regex rmm after booting into Android if that's helpful(?) (I have no idea how to use Logcat):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}

you did install fastboot drivers? Sometimes if you connect with a usb 3.0 port it dosent work properly

I've seen a lot of people say the S8+ doesn't have fastboot, there's also no "Reboot to fastboot" option in the recovery menu

Apparently Samsung's RMM server (https://rmm.samsung.com/) appears to be dead (SSL certificate expired and the entire server seems to not work)
So i'm wondering if there's a way to actually spoof the data the server sends, basically blocking Samsung's server and making my own DNS that resolves to my own server sending it's own data.
My problem then is, how would i even know what data my server is supposed to send? And would that even be possible?
I'm very much out of ideas XD
I also found this post (and i have a continuation file for my own phone so in theory it should work?) but it requires the use of iRoot and some proprietary sketchy Windows program. And iRoot and all of these one-click root apps have been known for injecting malware system-level into devices.

FIXED IT!!
The time trick actually worked.
All i had to do was turn back the time by like a year, reboot, enter recovery mode, delete cache, re-enable OEM unlock, spam the update phone button, and boot into download mode!

Nice work! tbh I'd never think of that lol,

The same goes. I have tried everything, and it seems that the post here suggests that we now entirely depend on Samsung to get the site certificate sorted out

I very much have no clue how it worked for me XD
It's very much possible, you just have to continously try.
I've heard rumors that if you have a Snapdragon chip instead of an Exynos, the RMM is doomed to lock until Samsung resolves their issue. But idk anything about that so i can't really confirm it XD.
I would recommend upgrading to Android 9 and doing the thing i said tho, that worked for me.
Also make sure that your ROM is from the country your SIM card is from, very important.
My phone was originally from Spain, and having a ROM that was made in Spain seemed to caused the RMM to continuously trip out since my SIM wasn't from Spain, so it essentially detected my phone as stolen or smth. You can find official ROMs on something like SamFW.
If this still doesn't work, try waiting 7 days again, then doing the thing i said.

friend please, could you say, step by step and in an orderly manner what you did? for example when you said "The time trick actually worked.
All i had to do was turn back the time by like a year" 1-¿have you done that after a flash, a hard reset, or just rebooted without deleting anything?, and also when you said "reboot, enter recovery mode" 2-¿what you did was restart directly to recovery, or restart the system and then restart it again to recovery? and lastly in the part where you said "re-enable OEM unlock, spam the update phone button" 3-¿"re-enable", if you said "re" it means that before reactivating it you already had it activated, right? 4-¿"spam button" by that you mean pressing many times, but, did you have the automatic updates box enabled or not, and... how many times did you touch the update button? thanks in advance, I would appreciate if you answer the 4 questions

which ROM were you using when you did theses steps to unlock? I've tried the 168hs+ method almost now and it didn't worked, then I found your post and tried doing this method changing the date and rebooting cleaning the partition but until now I couldn't achieve it, can you help me pleass
