What did you do differently that caused this to happen? If you have been rooted since May, I would think you must have done something in order for it to trigger that message. Would be good to put that information out there for everyone's benefit.
[T-Mobile Samsung Galaxy S6 Edge] PanchoPlanet:
Could it have something to do with "security updates" ?

I finally have root, TWRP, call audio and data without tripping knox on my stock GS6 5.1.1. I didn't think it was possible. Am I wrong? Has this been done already and I'm just late to the game?
[T-Mobile Samsung Galaxy S6 Edge] Malnilion:
I'm thinking you're late to the game. If you had fingerprint sensor working, that'd be something new. What matters most is if you're happy ?
[T-Mobile Samsung Galaxy S6 Edge] zgroten:
Is anyone else experiencing that, while on WiFi, the LTE icon keeps appearing and disappearing? Is this just a glitch or is my phone really turning on and off mobile data every two seconds? I saw someone else mention this but I forget where.
[T-Mobile Samsung Galaxy S6 Edge] the guitarist:
I went through the whole thread and i'm wondering can i use this (the modified kernel and TWRP) to flash a custom rom like "XtreStoLite Odex Pure Edition 2.0" ? i've been hearing stories about the phone getting blocked and Audio Calling not working. i don't really care about tripping KNOX as all i currently care about is getting a good battery life. after the OF6 update i can barely get 10 - 11 hours of battery life with low to moderate use. thanks in advance
[T-Mobile Samsung Galaxy S6 Edge] Aou:
I honestly don't know how to build without doing lunch first, so uh... I will continue to use the vendorsetup.sh. >_<
[T-Mobile Samsung Galaxy S6 Edge] Aou:
Seems that there are some issues using the Engineering Bootloaders you'll see floating around here - the ones that let you flash custom things without tripping Knox. The problem stems from them being 5.0.2 bootloaders, and trying to run 5.1.1 kernel/ROM on them will cause some issues with sensors and such. There's also some problems for G920T users that flash a G925T kernel - particularly call audio issues and some screen-flipping (which is reversible).

If you have the G925T and you are willing to trip Knox, then there's really no issues at all. I would read over the warnings in the OP, especially about freezing that app - that appears to be T-Mobile's way of detecting root/modified systems. So far, only one user has reported any major/unrecoverable issues regarding T-Mobile banning his device. Nobody's still quite clear about what happened there, but I suspect it had something to do with that app.

If you have EVER carrier-unlocked your device or have done ANYTHING with the IMEI, there's definitely some risk involved, but I don't know what the details are about this. I refuse to get involved with either of these two subjects.

So, other than what I'm mentioning above, there's been no reported issues at this time. Of course, there's always the disclaimer of "flash-at-own-risk," but I can personally say that I'm not having any issues with my device since flashing the latest TWRP and my own kernel. I love having root, mostly for freezing all the terrible bloatware.
[T-Mobile Samsung Galaxy S6 Edge] Aou:
Updated OP:

- Included new v13 build, which is more-or-less identical now to the official version.

- Added link to official TWRP page for our device (and announcement of official support).

- Updated build instructions for TWRP. Includes a cherry-pick from Gerrit, and the new device tree for zeroltetmo.
[T-Mobile Samsung Galaxy S6 Edge] steve97ta:
Picking the S6 edge up today and going to follow your steps. As soon as I have root I'm freezing those security apps apps.

I think it would be safe to flash Xtrestolite out of the box after rooting as he removes all that junk.

G925T Samsung Logo Stuck

Hello all,

Can somebody gimme support with my G925T, it was running perfect with the 5.0.2 and after flash the 5.1.1 from the stock firmware via ODIN G925TUVU2COF6 everything pass and after reboot it stuck at samsung logo. If i review the download mode and is in the next resume:

CURRENT BINARY: Official

System Status: Official

FAP Lock: Off

Secure Download: Enabled

So the only way to reboot succefull in to the system it´s flashing the Aou's OF6 Stock Kernel v2 or v3 or v4.

But if i flash the stock kernel or the Aou's OF6 Stock Kernel v1 again, gets stuck in the logo of samsung s6 edge.

So i can´t back to original stock even if i download the stock firmware from ODIN several times. The only whay is flashing stock firmware and put the custom kernel from Aou's OF6 Stock Kernel

Can somebody help me with this issue, why the edge dont boot with all files in stock?

thanks!
[T-Mobile Samsung Galaxy S6 Edge] mjdavis871:
Works great except OTG...would be awesome if we can get it supported.
[T-Mobile Samsung Galaxy S6 Edge] bigbiff:
Did it work in the release on twrp.me?
[T-Mobile Samsung Galaxy S6 Edge] vfox126:
Just wondering if there is any advantage to flashing v13 over official version from twrp or vise versa? Thanks for all the work. I have been watching this thread for a bit eagerly waiting for this and I know you guys have been working hard at it Thanks.
[T-Mobile Samsung Galaxy S6 Edge] the guitarist:
thanks for the detailed reply. i have the G925T and i have officially permanently unlocked it via t-mobile to work with other carriers and SIM Cards. is it still safe to flash your V4 Kernel and the V13 TWRP and flash a custom rom after that? i'd appreciate any feedback from someone with an unlocked T-mobile G925T Galaxy S6 Edge.

thanks
[T-Mobile Samsung Galaxy S6 Edge] steve97ta:
I picked up my 925T yesterday made sure it was running 5.1.1 and used this to root. Everything working great running Xtrestolite rom now? Great job!
[T-Mobile Samsung Galaxy S6 Edge] lilmikey201:
i dont see the patch anywhere? and ive already tripped knox so where is stock sboot?
[T-Mobile Samsung Galaxy S6 Edge] Aou:
Seems that some people who have either unlocked their phones or otherwise touched their IMEI (or EFS partition at all) are having issues with the 5.1.1 update. You might look into this thread or, for another possible fix, this thread. Mostly the 2nd one, as that seemed to fix someone else's issue in this same boat.

Not really, at this time, they should be the same thing (built from the same source), except it looks like one I've built technically reads 2.8.7.0 at the top, and the official one has 2.8.7.1. At this point, this thread is more useful for the kernel and the instructions on how to build TWRP for this device.

Awesome, glad to hear! And yeah, with a proper G925T kernel (with the custom tweaks to allow root and such), you should be able to flash nearly any S6-variant 5.1.1 rom. Just make sure you make good backups (e.g. TWRP backup and copy that over to your PC) of your device, in case someone's ROM does something nasty to your device's data partition. But otherwise, having TWRP means you can do a lot of experimental flashing. ^_^

Advised to find the stock Odin package for your device - it will include the proper/stock sboot, and of course everything else. Typically these packages don't wipe Data, so it's good to have a copy around in case something goes really bad.
[T-Mobile Samsung Galaxy S6 Edge] hieupham:
Hi friend, I flashed the official 5.1.1 for the G920T (Tmobile) unlocked phone from rooted 5.0.2, yeah as you can expect after that the phone just stucks at the ANDROID starting screen (bootloop); flashing your custom kernel wakes it up.

After everything is OK, the system popped up the Security notice that the system has been modified etc etc; restart your device to Undo; OK so I tried it and now the phone bootloops again. ( 'Unauthorized actions have been detected. Restart your phone to undo any unauthorized changes.' )

Even worse, it will not allow to flash your custom kernel; on the boot screen it goes:

RECOVERY IS NOT SEANDROID ENFORCING

Custom binary blocked by FRP Lock.

and then auto shuts down the fone; I can flash 5.1.1 stock via ODIN and to try flashing the custom kernel but failed.

System status: Custom

[T-Mobile Samsung Galaxy S6 Edge] steve97ta:
Sounds like you need to freeze the security apk mentioned in the OP. This method worked just fine for my TMO S6E today
[T-Mobile Samsung Galaxy S6 Edge] mjdavis871:
Does not work..I can't mount OTG nor can I read/write to it.
[T-Mobile Samsung Galaxy S6 Edge] mjdavis871:
So I'm not used to the options to backup...what would the right options? Boot, data and system r/w? What is the advantage to backing up system r/o?
[T-Mobile Samsung Galaxy S6 Edge] Aou:
For the backup, it couldn't hurt to grab a copy of everything. It's the restoring where you sometimes need to be more careful (e.g. restoring EFS stuff could be problematic, theoretically... or overwriting your data would revert your data back to that backup... or restoring cache can have some weird side-effects...). Also, don't forget to scroll down.

To save time, you can skip the MD5 creation. I never use it. I assume it's useful for people posting the backups online - it makes sure that the backups make it from Point A to Point B in-tact.

I would do the System R/O instead of R/W.

R/W is a file-based copy. R/O is a full "image" backup (similar to using "dd" to pull a copy of it). For our device, R/O is recommended in most cases.
[T-Mobile Samsung Galaxy S6 Edge] hieupham:
Yeah you got exactly the point here Boss, the new 5.1.1 security stuff prevents loading any custom/ modified things (that's it, not stock or original) , by default the Flash Prevention stuff is ON in the new 5.1.1 and normally people don't take the point into consideration; if to put it off in the Developer option before proceeding the RESTART, then it's supposed to be OK.

The problem now is that I can flash the official ROM, but it bootloops (as many experience in here, don't know why, even the globally unlocked fones go into bootloops, 920F/i/T...) mostly the GOLD Platinum version; and it stuck at the boot logo, and IT WILL NOT LET YOU to flash the custom kernel again, so you can do nothing, as you cannot boot the fone to switch off the Flash prevention in Developer Settings.

---------- Post added at 08:18 AM ---------- Previous post was at 08:11 AM ----------

It was a 5.0.2 version on my T-Mobile 920T, rooted to install the local language, and that's it, nothing more, even the carrier apps are still there. After that I do the ODIN fresh install to 5.1.1 and here it comes, the bootloops (I think due to the new security mechanism of SS) and never let you go back to 5.0.2 again.

Normally if 5.0.2 to 5.0.2 everything is fine and the fone is stock again, no problem.

The interesting thing is that, even your phone is stock. e.g, you go to 5.1.1 OTA from 5.0.2, you can boot it normally; but as you do the FACTORY reset, it will bootloop.

=====

Regarding the package from Vietnam, actually the just un-zip the stock rom and then create again the 4 files, the 1st 2 files (A+B) will be enough, the rest will be needed if the 1st method will not work. In the recompiled files, they removed the cache.img, hidden.img.

Interesting tho, that in this topic: http://xdaforums.com/tmobile-galaxy-s6-edge/help/completely-bricked-s6-edge-g925t-help-t3146069 the guy was able to flash the stock ODIN and everything OK, in my case after flashing stock ODIN, it just bootloops; but now with the FRP on, even worse, will not let to flash anything custom.

PS: In that very Vietnam forum, the guy stated that it's the ROM's problems, not the devices.

[MENTION=1124755]Aou[/MENTION], is there an updated kernel you made for us 920T users, or is it possible to flash the 925T kernel and than update the touch fw via dialer? Thx.
[T-Mobile Samsung Galaxy S6 Edge] Aou:
There is a G920T kernel in the OP now - should be basically identical to the G925T v4 kernel, but built with the G920T source.
[T-Mobile Samsung Galaxy S6 Edge] jaxenroth:
With the same call audio fix for phones with eng BL?

Edit: Still version 1 of the 920t kernel not version 4. Sorry I misunderstood you.
[T-Mobile Samsung Galaxy S6 Edge] the guitarist:
would you mind telling me if you're facing any problems? and is your phone unlocked? i have my phone paid in full and permanently unlocked and i'm afraid if i flashed a custom rom i'll lose the SIM unlock or have my phone locked for running a custom firmware or something like that. thanks
[T-Mobile Samsung Galaxy S6 Edge] Aou:
It is my understanding that on the 920T, flashing the 920T engineering bootloader (5.0.2) and using a 5.1.1 kernel will yield its own problems, such as the fingerprint sensor. However, I believe the call audio problem creeps up when people are flashing the UniKernel or the 925T kernel. I believe I've seen reports that flashing the 920T custom OF6 kernel does resolve this.

As for the version difference, the V1 of the 920T kernel just my first revision/build of that kernel. It has all the same mods as the G925T v4 kernel, but I got it right on the first try with the G920T ;)

I'm curious also. I've seen so many reports of people upgrading to 5.1.1 and having bootloops, purely because they've gotten their phone unlocked. I'd like to see some reports that suggest otherwise.
[T-Mobile Samsung Galaxy S6 Edge] brandonc0526:
What version of Odin is everyone using? I can't seem to get the recovery to flash, although kernel flashed fine. I used 3.09 and 3.10.6
[T-Mobile Samsung Galaxy S6 Edge] Aou:
v3.10.6 here. What file are you trying to flash, specifically? I've seen some weird cases where downloads get corrupted intentionally by security software, proxies or other means. Are you getting any specific errors in Odin? Does it fail MD5 check? IF it's failing MD5 it's definitely a corrupted download.

If you're downloading one of the other files (.tar or .img or .zip), then there's no MD5 check. Also, .zips and .img's are not odin-flashable. I'm assuming you knew that already, but just making sure (and always helpful for others following along... creepers.....)
[T-Mobile Samsung Galaxy S6 Edge] brandonc0526:
Thanks for the reply bud. It would say success but the phone would just stay at downloading in Odin mode. I turned it off with the 3 finger reboot and it ended up in TWRP so I'm not complaining ?
[T-Mobile Samsung Galaxy S6 Edge] Aou:
Weird! Glad to hear it's working!
[T-Mobile Samsung Galaxy S6 Edge] brandonc0526:
Been a while since I've done Samsung phones. I had a galaxy S 4G which was just about the same level of ease as a nexus. But after that it's been every nexus so it was a but confusing using Odin again. I just think it's weird that the phone didn't turn off or even acknowledge that the flash completed. I did it 3 times, kernel went through just fine. Thank you for your hard work though, seems you do a bit more work than nexus Devs!

[T-Mobile Samsung Galaxy S6 Edge] steve97ta:
My phone is just a jump upgrade right from Tmo. I didn't do anything to special to unlock

it. Just make sure the right Firmware for your model is used to update to 5.1.1. Also be sure to disable the reactivation lock and go into developer options and be sure the bootloader is set to unlocked.

I followed the OP then made a backup. Now I'm running Xtrestolite custom rom. No voice issues like many complain about. Just gotta do some reading.
[T-Mobile Samsung Galaxy S6 Edge] Aou:
I should probably add this part to the OP.
[T-Mobile Samsung Galaxy S6 Edge] steve97ta:
Might be a good idea I've never ran into this before being this phone. Been rooting since the Evo days and looked through the phone before rooting as I like to feel comfortable in what I'm getting into. Crazy how they just put that in there.

Odin flashed the 2.8.7.1 TWRP from the TWRP official site. Works great, except it hangs every time I try to reboot system. I have to hold vol down + power to kill it. Using the terminal in TWRP I can use the command "reboot system" and it works just fine.

Any troubleshooting steps would be greatly appreciated! Thanks for all your hard work on this recovery for the G925T!

Edit: G925T, took OTA to 5.1.1 COF6. enabled oem unlocking, flashed an earlier version of TWRP from this thread, running xtre sto lite odexed, then Odin flashed the official build from twrp.
[T-Mobile Samsung Galaxy S6 Edge] steve97ta:
Simple as that, aou made a twrp in the OP that works great as well no freezing issues
[T-Mobile Samsung Galaxy S6 Edge] intramorph:
What I really want to know is why root in first place. What can I get with root that i cannot do without. I had HTC M8 and understood the power of S-Off and flashing custom roms but here I'm a bit confused. Can some older member explain it in lame's terms pl0x

Rooted Phones: Do NOT allow "com.tmobile.pr.adapt" to obtain root permissions, EVER. There have been a couple reports of devices becoming IMEI-locked by T-Mobile (goodbye voice & data!), and I highly suspect this app (or a new version/replacement of it in leaked upgrades) is what T-Mobile is using to determine if your device has ever been rooted. I would recommend freezing/disabling this app as well.

This kinda scares me to even atemt to root my device
[T-Mobile Samsung Galaxy S6 Edge] chastity:
They won't block your data or voice because you're rooted. They MIGHT void your warranty but I never had that happen on any phone. I've been with TMO for 8 years and they always honor the warranty even with rooted, custom ROM and KNOX tripped.

If you're rooted you just do as the OP says: Use Titanium to freeze the app.
[T-Mobile Samsung Galaxy S6 Edge] Malnilion:
I don't think that's what's causing people's IMEI issues. I think those people tried some weird **** in order to carrier unlock their phone instead of doing it the official way through T-Mobile. I have no sympathy for them.
[T-Mobile Samsung Galaxy S6 Edge] PanchoPlanet:
In the good ole days root was simple and fairly safe with multiple choices when it came to custom roms or recoveries.

You had to go out of your way to mess up root especially if you where using CF autoroot, and after root it could take you days to pick out what ROM or mod you wanted to try because the choices at times seemed endless with multiple devs cranking out so much work.

That was the era of the "Flashaholic" , but today circa 2015 rooting is a whole different ballgame especially if you don't read a thread and follow it for a good while from OP to end viewing how members mess up and recover (if recovering is possible) .

Samsung and T-Mobile are complicating root with apps that check for root or unofficial installations, security that can fowl up your phone, and even bootloader FRP that causes your IME to get locked and your phone gets the "factory protection brick" , this is what Samsung puts in place so that if your phone is lost or stolen and attempts are made to modify software or IME the phone turns into a useless paperweight.

Its these features and risks that are keeping my phone stock for now, and this is a record for me, almost two months with a stock phone, usually I'd be rooted in just 15 mins out of the box. But this is to risky to take chances and wind up with a phone with inoperative features or worst yet a bricked phone.

I rely on my phone daily for communication, yes I use it as a phone 98% of the time, and I want this gold colored device that I paid 700+ for to work every time, and it does! ;)

Stock is OK by me for now, have over 40 apps disabled, phone sleeps like a rock at night, battery will last 30+ hours, all the high end features that make this phone awesome WORK every time I pickup the phone (no resets or restarts or nandroids necessary) . ?

When Chainfire comes up with the proper "safe" root procedure, I will Root,

Then I can install my RomToolbox pro and delete some more bloatware.

Until then, stock works for me!

So you decide, to root or NOT to root?

This is my take on root.

Pp. ?
[T-Mobile Samsung Galaxy S6 Edge] Jdom58:
You are correct in some aspects here, TMob won't block your data or voices because you're rooted, the phone's software will block your IEMI and not allow data or voice to transmit and gives you a security message that "This phone has been flashed with unauthorized software is locked, call your local carrier" from that point you are screwed because there is no getting out of it and you can't get rid of the message so neither TMob or Samsung will provide warranty. There is no sending the phone in for warranty (they will just mail it back to you) and there is no trading it in on jump and I've been a TMob customer for 15 years. In the past yes, I jumped with a rooted M8 no problems, from what their Corp office told me that is not the case anymore, will some rooted functioning phones slip through the cracks via jump sure, will you get warranty done nope they will check them for root.

I was rooted, unlocked, with TWRP, running 5.1.1 perfectly and made a mistake flashing what I thought was a updated firmware for our phone. When it went into a bootloop I figured I would just odin back to complete stock. After it booted up fine is when I realized I had the security issues.

[T-Mobile Samsung Galaxy S6 Edge] Aou:
Updated the warnings. How's it sound now?
[T-Mobile Samsung Galaxy S6 Edge] Lexee:
Let me tell you why using Galaxy S6 Edge without root is not an option for me. With root, you can

- Replace whatever emoji font you have with "standard" Apple emoji (the kind you see in whatsapp and on iphones)

- disable Home button from waking screen (accomplished by for ex. swapping APP_SWITCHER and HOME button mappings)

- Use Lightflow software to take full advantage of notification LED (configure different LED colors and blinking patterns for different events)

- disable waking screen when receiving new SMS/MMS in stock messaging app.

- get rid of carrier-installed, otherwise non-removable bookmarks and bloatware.

- use Titanium Backup to fully back up and restore your device. When switching devices, be able to transfer 100% of your device data, including things like messaging history in Whatsspp, Viber, etc etc etc.

- preserve time stamp when uploading files to your internal SD card. You do that by running adbd as root and uploading via "adb push" rather than through regular MTP.

- disable tethering provisioning and use native tethering: if you choose to share your data connection with another device, this decision should be only up to you and no one else.

- When Xposed framework comes out for ARM64, use it for ex. for controlling media playback with hardware volume/power buttons.

- Last but probably most important: always know that YOU are the master of YOUR device, and not some wireless carrier, manufacturer, government, or whomever.

As for "imei-locking" of rooted phones - trust me it's a bunch of bs and urban legends ;)
