Are there any special recovery modes to learn about? - T-Mobile Samsung Galaxy S6

This is my 1st Samsung device and I'm coming from a LG.
LG phones typically have a "Download Mode" separate from the recovery boot. Its a useful tool that can reflash the phone to stock conditions, even if you managed to somehow mess up the rom and the recovery. As long as you could get into Download mode, you'd always recover from any brick.
So does Samsung or Galaxy S6 have anything like this? Or is it rooting and recovery flashing as normal and pray the recovery never fails...

Samsung has a download mode as well, which is contained in your secondary boot-loader. You can access it via "adb reboot download" or from a power-off state holding: power, vol_dn, and home buttons down until you see the download mode warning text (you may have to release power a bit before the other two if the phone keeps rebooting just as you see download mode come up).

Thank you!

Flash gone wrong

Hi,
I've flashed multiple times before without an issue until today.
First, here's my background information:
Samsung Captivate (ATT)
Was running Continuum 5.4.1 but it felt laggy so I attempted to flash MIUI 1.5.13.
Here's what I did:
I wiped my phone using the Odin One click tool, then flashed CM7's kernel and then performed formats of the cache, system, and data, then installed MIUI RC2. After this step the phone should have restarted, then I planned to shut it down and reboot into recovery and flash 1.5.13 onto it.
My problem(s):
-Boot into recovery/download mode using key combinations is not working.
-The ADB console reports device not found when I try to run adb shell.
-The phone is undetected in Droidexplorer.
-When I attempt to download an app to boot to recovery with the phone says there is no space even though nothing has been installed other then MIUI.
What I would like to do:
Get back to stock with download/recovery modes working.
On a side note: MIUI works, but in a very limited way. I can navigate through it, but it won't allow the installation of applications due to there not being room on the phone (as said before).
Thanks!
Update - my phone was being identified as a Nexus S, so without those drivers my phone could not be debugged via USB. I now have the drivers and can perform ADB commands, however rebooting into recovery and into download mode both result in the phone restarting without going to the download or recovery mode.
Try using ODIN and repartitioning. I have good videos on standard ODIN and Heimdall on YouTube just search them. If you can not get out of this contact me, I have been able to partition debrick in the past and it's actually considered by me far more annoying than standard bootloader JTAG in certain situations. Let's hope yours is easier to bail out of!
First of all thanks for the reply and direction.
Secondly:
After working on this all last night I was able to get the phone recognized by Odin and my computer, now I am stuck at one of two screens depending on what I do.
If the phone is powered off then plugged in, the battery charging screen appears but there is no animation and after unplugging it the battery charging image remains.
If I power the phone on it hangs on the Samsung boot screen.
Repartitioning does sound like the proper direction for me to take, but, when I use Odin it freezes while setting up the connection to the phone.
when the phone is powered off try holding both vol keys and plugging in the cable. That could possibly get you to download mode. If not try vol down/pwr at the same time since you are now on GB bootloaders the keys are a bit different. Let me know what happens and good luck
maybe you should try to build a jig and use it to get into the download mode first. or you can buy it on ebay, just search for "micro usb jig".
I've tried every volume and power combination possible to no avail, I can't get into download mode. I've given in and am exchanging my phone. Thanks for the help anyway guys!

Recovery Flash Issue

Ok so I'm not sure what the issue is but, I'm rooted and Bootloader unlocked, went to flash a recovery, I reboot and it boots into CWM, when I boot back into the OS , turn off the power, then boot into recovery by holding down the buttons, the custom recovery is gone. I can reflash it and boot into the custom recovery but I loose it everytime. Its like its only temp rooting. I've tried CWM Rom Manger and Flashify, it does the same thing.
@TabascoTX some devices have stock recovery restore scripts. I haven't dealed with your phone model yet mate, so better check your threads to find the answer.
Just few examples:
On Samsung Tab 2, S3, Note etc it is enough to wait 30sec after flashing custom recovery, then disconnect and turn off, then boot directly into recovery with buttons combo.
On OPO the script must be disabled in settings, option "update recovery by OTA system updates".
There should be some kind of similar solution also for your Motorola

Its really odd. I'm missing something somewhere. I've rooted and installed CWM on a few of theses (5 lines with ATT and we all got the Atrix HD). Ive never had this happen before tho. I'm not sure why the recovery wont stick. And for whatever reason I cant get my computer to recognize this phone with fastboot either........
OK..I'm an idiot. found the solution here : http://forum.xda-developers.com/atrix-hd/help/qa-cwm-6-0-5-1-jbbl-t3009075 Last post.. totally forgot to rename the scripts... Geez...You were right tetakpatak, its been a while since I messed with my Atrix. Still cant figure out what the issue is with Fastboot tho.

Soft-Bricked Moto G (2014) won't move beyond Fastboot

Hey guys!
So I've got an issue I'm struggling with on the Moto G (2014). First I'll tell you as much as I can about the phone: I bought it from the Motorola website, so I think it's running whatever the stock firmware is. Also, it's the 8 GB US model and isn't tied to any carrier. (I have it on T-Mobile, but got it directly from Motorola. I was trying to figure out what the firmware is but the closest I've been able to get is by running the Motorola Device Manager app while the phone is in fastboot mode. It says there are no available updates for: 21.11.17.titan_retuaws.retuaws.en.us The bootloader is locked and the phone is not rooted. It's pure stock, though it might have automatically gotten an OTA update to the latest official release, I can't be sure because I bought it for someone else.
Okay, so the problem. I'd bought the phone for my dad and set it up and it worked fine for about two months. Yesterday, he came by my place and asked if I could take a look at it because it was stuck on one screen and since there was no removable battery, he didn't know how to reset it. The screen it was stuck on is the boot screen where the Motorola logo is supposed to come up. It was up, but the bottom half of the logo was stretched to the side and pixelated so my first reaction was "crap, he hit it against something and there's damage to the screen." But there was no visible damage to the screen anywhere (neither from a hard hit or from pressure) and he's got the flip case for it and he said it hadn't been hit or anything.
I tried to power it down by holding down the power button, but as soon as it went off, it tried to start up again. A bootloop that always froze on that messed up Motorola boot screen. I set it on the charger for a bit and let it run through the loop a few times and at one point it got as far as the "world" screen where it shows a cartoon planet. This extended down past where the weird stretch happened on the motorola graphic and it was perfectly clear so I realized there was no damage to the screen, just some sort of boot error.
So then I tried booting into fastboot (hold both volume buttons down along with the power button for a few seconds, release) and I was able to get into fastboot. I tried scrolling down to recovery and then hitting the volume up key to select it but the second I hit the volume up key (the selection key in this mode) it reboots the phone. It doesn't go into the recovery screen, just turns off the phone. I tried this for the "Factory" (reset) option, for the "Normal Powerup" option, and the others. Instead of getting anything different, selecting any of them turns the phone off and nothing happens. The computer is recognizing that there's a device connected to it when I have the phone plugged in via usb in fastboot to my Windows 8 laptop. It also appears that I can enter commands in fastboot. (Though I'm not sure what to put in to fix this so I'm turning to you guys.)
So I can't figure out what's wrong. I've got some experience in flashing roms, both manually and with some of the tools, but haven't had to deal with what I'm assuming is a soft brick before.
Can anyone offer any help?
Thanks very much.

Unfortunately that didn't work. I was able to click the "restore to factory" part and it seemed to do that but I tried it again with the "wipe cache partition" and it just reset. I tried to restart normally and nothing happened. I will start boot and go to the Motorola logo but will always fail there, no matter what I try.
I'm still stuck with the soft-bricked phone. Any help going from Fastboot to somehow getting it to work?
(As I stated in the OP, the recovery options don't work. It seems only the Fastboot area is working.)
try to reflash the rom via fastboot, using the commands on 4.2 on this thread
if you have fastboot working they must work and re-flash the stock rom and everything back to stock...
to have the XML zip of yours rom search in here and download the file regards yours model and OS version that you wanna...
download, very slow download, unzip, to the some folder of mfastboot and give the commands a try... :good:
This is how to solve *ANY* softbrick on the Moto G 2014 (2nd Gen Moto G)
Try unlocking your bootloader with the given instructions on Motorola's website. You can flash a recovery like TWRP or CWM using mfastboot-v2. After flashing the recovery you can reinstall a custom ROM or stock ROM to fix the soft brick. ADB is only available if you enabled USB debugging although it will allow few commands. Using mfastboot-v2 after unlocking the bootloader will play the main factor in resolving the soft brick.:laugh::good:

hello eyhajee.
My Moto G 2014 xt1068, running on Android 5.0.2 has some softbrick issue.
I have unlocked its bootloader, rooted it, unrooted it and while I was trying to lock its bootoader, I forgot to enable USB debugging and now it's stuck on fastboot mode.
So I wanna ask that can flashing a custom ROM turn my phone on??
I think so. If you are able to run some basic commands you should be able to flash it to emergency mode.

Sprint Note 5 Boot-looping trouble!?

This is my first post and I'm in need of some help that I can't seem to find anywhere when searching the internet. I'm not a developer nor am I close lol I just have tons of fun learning the development process - it's seriously one of my favorite things to do. Anyways I've messed up royally with my Galaxy Note 5 N910P and I'm stumped on what I should do next! So here's the issue: My Note 5 will not stop boot looping!!! I've flashed stock, almost every version that I'm able to and nothing has worked. The last thing I remember doing before it started this b.s is rooting with CF Auto root. I've always used twrp then flashed Supersu and the dm verity and never had issue! But after flashing the CF Auto root I kept getting kernel is not seandroid enforcing and then the dreadful boot loop issue that has been going on for three days now! Is there something i'm missing? or not doing right? Please message me and let me know, and if this is the wrong place to post about this, I dont mind if my post is taken down just at least help with my question some how! Thank you, XDA is my favorite place - you guys are awesome, I don't trust any other source!!!

First of all you have entered wrong model no here note 5 model no should be SM-N920xx
1)Have you enabled Oem unlocking from developers option before flashing twrp and cf-autoroot using odin? If not then you done a mistake!!
2) Have you tried to flash latest stock firmware using odin with latest usb drivers installed on you pc and proper odin flashing guide?(Flash latest 6.0.1 for your device with latest usb drivers installed on pc and connect phone to main usb port using original usb cable) After flashing stock rom if your facing bootloop then you can try reset through stock recovery (Press volume down+power button to switch off your phone..When screen shuts off immediately press volume up+power+home key simultaneously untill you see Samsung galaxy note 5 logo, release keys..You are now in stock recovery from there choose wipe data/factory reset..After reset complete reboot your device)
3)If you can boot into twrp recovery normally then flash any custom rom suitable for your device i.e. for sm-n920p..Custom roms are pre-rooted so no need to flash cf-autoroot..Flash custom rom, if you successfully boot up the rom( It's difficult to boot custom rom though if you haven't enabled oem unlocking you will face custom binary is blocked by frp protection),then enable oem unlocking from developers option and try flashing stock rom again
4) Next option for you is download Samsung smart switch for pc, install latest usb drivers on your pc, connect your phone to pc in download mode(Press volume down+power+home button simultaneously),in smartswitch select emergency software recovery, it will ask you imei,model no and serial no which you can find either on box or back panel of your phone,smartswitch will detect latest stock firmware for your device, hit update now,give some time until update complete..Your device will be automatically reboot..If even you face bootlopp, then goto stock recovery(Press volume down+power button to switch off your phone..When screen shuts off immediately press volume up+power+home key simultaneously untill you see Samsung galaxy note 5 logo, release keys..You are now in stock recovery from there choose wipe data/factory reset..After reset complete reboot your device)
**IF SUGGESTION IN SECOND POST HELPS YOU THEN ITS DONE, AVOID NEXT SUGGESTIONS**
Are you sure you can't install cf auto root again to solve it? IF not...
I did a search and got hits for twrp for N910P. Get it loaded, get it wiped and have another shot at success. Next way to get rid of the persistent rooter gone rogue, load up a factory BL + AP. If that doesn't work download another version and try again.
I've enabled OEM unlocking, flashed latest stock AP...BL.. And so on, factory reset in both factory and TWRP. I have also tried flashing CF Auto root again to see if that would fix it also custom ROMs bootloop except for CM13 and Lineage OS- Which is weird because the ROMs are for the SM N920C model and I'm and Sprint model, So I don't understand that. Weird!! Everything recognizes me as SM N920C except when I am in download mode. Also, having no imei or any back ups make its even harder since my computer completely crashed on me because I am unable to use Samsung smart switch due to the wrong model and null imei. So I'm completely stumped with this issue. Not sure if its a corrupted partition or folders not being in the correct folder locations along with wrong permissions, I've literally stressed everything to my knowledge about this and I'm all out of what issues this could be related to

How to recover from Verification Failed, Bootloops, and Android/Carrier logo freeze.

In this tutorial I will inform you on three different soft bricks, and how to fix them.
You must be able to boot into TWRP and/or Odin/Download mode!​
1.) Verification Failed.
Method #1
This method will work with people whom can't reset their device, due to an unmountable /data partition, and those whom experience this error, who can reset but have valuable items, applications, videos, or photos that they don't want to lose. Must be able to boot into Odin/Download mode. (Volume Down+Home+Power)
The solution is actually pretty simple. Boot into Odin/Download mode. This has to be done correctly, not from TWRP recovery. When the prompt for "Volume Up = Continue" and "Volume Down = Cancel (Restart)" press volume down. You should no longer see verification failed, but instead be sitting on the T-Mobile logo. This is normal, and could take 30 seconds to 10 minutes, depending on the amount of data.
This method works all because of Knox. Knox is what Samsung uses to void your warranty. Companies are not allowed to void a warranty when rooting, installing roms, or recovery, unless they have direct evidence. Knox will trigger this when it isn't sure. It will try forcing you to bring it to Samsung, and they can directly find out why it was caused. This happens when it thinks that you cancelled.
Method #2
This one will require you to lose all your data, but is mainly intended for those whom cannot reset their device. Download the stock firmware from the links below. Open Odin (Jodin3 will not work! It is not fully functioning, do not try it.) and boot device into Download/Odin mode. On your computer, you should see 'Added' in the logs. If this does not show up download the Samsung USB Drivers. Select AP and then select the stock firmware. Now flash it. This can also be done through TWRP
For bootloop and frozen Android/Carrier logo just do Method 2. You usually will keep all your data.
FOR 'VERIFICATION FAILED' YOU CANNOT RESTORE FROM A BACKUP!
FOR BOOTLOOPS AND FROZEN STARTUP SCREEN, YOU CAN!​

Please describe this issue in further detail. Has this been happening out of nowhere, or did you just try flashing something via Odin/Download mode or TWRP.
Also, before flashing did you enable OEM unlock
This also happens when something flashed via Odin/Download mode is incompatible.
Are you still able to boot into the default system partition? If not safe mode?

I should have updated my post, I'm not sure what happened but I flashed stock through Odin and the problem went away, after that I was able to flash twrp and root/install other roms.
It's still weird that the problem happened out of nowhere, not sure what triggered it.
It goes away when u log in to google with the last account that is associated with the phone

Probs OTA. It happened to me my first 3 tries. Ended up factory reseting, and installing fresh via Odin, didn't fix it.
I just turned off auto reboot on Odin, and then pulled my battery on my J7. Booted up straight to Recovery from there.

Sorry I didnt respond.
Looks like you didnt flash encryption breaker. Keep this on your SD Card as its a great way to recover from these errors, and you will need it when you flash ROMS.
Just boot in recovery, flash ashix no verity no encrypt, then reboot into system. You shouldnt have this error.

He's referring to the encryption breaker file ("no-verity-no-encrypt_ashyx.zip") in his first sentence. That is assuming you already had it and should be keeping it on your SD card all the time for flashing ROMs

Was the update sent out to you, or did you download it from SamMobile?
If the update was sent out to you I'm afraid I cannot help, but if you flashed it from SamMobile use an older version like Marshmallow or Lolipop.
EDIT: Make sure you factory reset device and wipe cache after installing from SamMobile.
