Trying to get TWRP installed on an old S6 (with no SIM card), on the way to getting a newer Android on it.
Device is freshly factory reset, I do not believe that it has ever been rooted.
Per
, I have been using Odin to load twrp-3.3.1-0-zerofltespr.img.tar. Odin indicates success, but after that, if I try to get into recovery mode to use TWRP (volup+home+power), I get a blue "Installing system update" screen, then a "No Command" screen. It then drops into the stock Samsung recovery screen (zerofltespr7.0/NRD90M/G920PVPS4DRC2) instead of TWRP.
Did I miss a step? I saw something about the stock boot writing over TWRP, but the sequence of operations to avoid it did not make sense to me.
Found the missing step in
Needed to uncheck Autoreboot, then VOLUP+VOLDOWN+MENU+POWER.

Have a Verizon Samsung Galaxy Note II (SCH-i605). Took the latest OTA update to VRUEMJ9. Have since rooted and installed SafeStrap and was happily running N3BULA ROM, when I decided to explore a bit and tried to flash Alliance ROM. Now I'm stuck on the Samsung boot screen and can go no further. I am able to access Android system recovery, but when I try to 'apply update from external storage' I get 'E:signature verication failed' message. Tried to flash to stock via Odin, but unsuccessful. Shows Added in Odin but nothing happens when I select the .pit file or the .tar file. This is a work issued phone, so any help to get up and running would be greatly appreciated!

Have you performed a "wipe data" option from the recovery after flashing the alliance ROM (it wipes your user data)?
Because I just visited the alliance ROM thread ( http://forum.xda-developers.com/showthread.php?t=2032447 and in the install instructions its mentioned so.
Better take a little time and properly read the install instructions during flashing..

I never had that option. I've flashed numerous ROMS before and am pretty meticulous when it comes to following instructions. It appeared to have a custom flash script which allowed me to pick what I did and didn't want to install. I tried to keep it mostly stock and when it completed, it automatically rebooted (didn't give me an option to 'wipe data') and now leaves me stuck on the Samsung Boot Screen. I was able to flash the .pit file via Odin, but keep getting a 'MD5 hash value is invalid' when I try to flash the .tar file.

You should enter into recovery and then manually wipe data..
Also if that thing doesnt work, then have a look at this thread which explains how to go back to stock rom..
In addition,
A. Why doesnt Odin work?
Did you unextract the tar and pit from the rar/zip so that odin could recognize the files as suggested in dagger's link in section 1b step 2?
Did you install samsung drivers on your computer properly? You may use this toolkit for that
B. Rescue by CWM
Signature verification failed is caused (I think) by stock samsung recovery's choosiness, if you are sure you downloaded the zip correctly. What zip did you exactly try to flash?
So now, you may want to flash a cwm recovery or a kernel that contains cwm inside. Flashing usually uses adb using fastboot. Search "flashing a recovery image" or "flashing a kernel" where your chosen kernel should have cwm inside. cwm usually does not put out that signature verification error.
Remember:
You can access recovery mode through an app or by pressing a button combo when turning your phone on. Device specific.
Stock samsung recovery can wipe data.
CWM can also wipe data, and is the preferred installation method for most/all custom roms. And it can make a nandroid backup.
If ever you do choose to flash, you'll need the toolkit to install adb/fastboot drivers, but maybe since yours in locked bootloader the adb thing might not work.
Hope this helps
I am having some serious troubles with upgrading my Galaxy Note 4 SM-910P (Sprint). All was well in rooting, un-rooting, etc... I have the original 4.4.4 and the new 5.0 backed up and now I can't use anything other than the firmware the original firmware package through Odin. The problem started when I installed the [ROM]ViSiON-X N4 SPR 5.0.1 [Android L 5.0][N910PVPU1BOB7-R1][03-11-15]. It installed fine but when ever I was not watching it a problem occurred such as getting locked out of ny ext SD, or just plain un-rooting itself. It finally came down to it just kicked my device into download mode and would not reboot. I did used chains Odin root method and installed TWRP, which I can still do but can not flash or restore from TWRP or CWM recovery. It will take the firmware package fine and download the 5.0 update but always gets stopped from any other upgrade at recovery be it stock or custom. I have even used Kies to try and upgrade a few time. It will upgrade from NK1 to NK2 but still will not upgrade anything else past recovery. Every time I reboot I lose my WIFI password. After every boot it takes a minute for any network to be able to reach the device. It is paused until I re enter my WiFi password then it will say that Android is done upgrading and there is a toast message that says "device is set to factory mode some items won't work on this mode set device to user mode". Can someone please tell me how to set my device to user mode or erase what ever is lockled in my device between download and recovery. The issue I described with the device wanting to stay in download mode and how to handle it is described her http://forum.xda-developers.com/showpost.php?p=59372208&postcount=3 but as I mentioned I can't get passed anything that is not firmware through Odin. If I had to be locked in one version forever I would have preferred it be 5.0
I figured it out

I fianlly figured out the deal with TWRP not flashing.
The change between file systems is what TWRP won't flash.
To flash into the new, the old, or back up property check the file type.
Ext 2, Ext 4, F2FS, etc ...
To get recovery to load install from odin with auto boot disabled, remove battery, than vol + - menu and power.
the steps below..
1. Power off (complete) boot to download.
2. Load Odin, uncheck auto reboot, PDA TWRP. after it installs pull battery to exit.
3. Boot to recovery - wipe- advanced wipe -Repairor Change File System - Check System (go thruough each)
4. Repair and change each to the file type you want to flash
5. repair and or change the files for the zip you are going to flash
6. you have done all the rest before ....
Issue resolved, thread closed, thanks.
Hi,
okay, so i had a rooted samsung j500f phone running android lollipop 5.1.1 stock rom (downloaded from sammobile). I was using Apps2Sd for linking my apps to the external SD Card. Few days ago, my phone turned off on the battery getting empty and when i turned it on, all linked apps were missing. I was getting an error that "Disable mount namespace seperation in Chainfire SU". I did that but nothing happened and the App2Sd was unable to remount 2nd partition.
Frustrated, i contacted their developer who suggested to reinstall SuperSU. So, i opened the SuperSU app (chainfire) and went to settings and then chose the option "Reinstall from google play store". It uninstalled SuperSU which i later downloaded from Google Play Store. After it had installed, it asked to install binaries and gave me two options:
1) Normal in-app method
2) TWRP/CWM recovery method
I chose the second one (because i had TWRP installed).
Then my phone rebooted into recovery and ran a few scripts. However it later stated that there is no root on your device (which i believe may have been removed when SuperSU was uninstalled). TWRP gave me options to reinstall SuperSU but it did nothing. I downloaded the latest SuperSU zip file from chainfire site and tried to flash it. But the script would show failure. Now, my phone wouldn't boot into the system. Only into recovery mode.
Being really pissed, i decided to do a factory reset. So i did a factory reset from within the TWRP (normal wipe). Still, my phone wouldn't boot but would go to recovery. So i got angry, went into the Advanced wipe option in which i selected dalvik cache, internal storage, SYSTEM and wiped them all.
Now on trying to reboot, TWRP would say "There is no OS installed. Are you sure you want to continue?"
I knew i had messed up my phone and so i decided to flash it with stock rom again using ODIN. But, whenever i try to go into download mode it gets stuck on the Samsung Galaxy J5 Logo screen with "ODIN Mode" written on the top left along with a couple of other details such as Knox void 0x1(4), Rom statusfficial, etc.
Clearly, i am unable to flash using ODIN as my phone isn't being able to go to Download Mode. ODIN doesn't detect my device.
So i thought of flashing the stock rom using TWRP, which failed.
I also have a TWRP Backup but TWRP won't let me select it. I have the backup folder on my SD card.
Now my phone has just TWRP, Can't get into download mode using the key combinations or through TWRP bootloader option which on selection gives me the "No OS" error. I can't boot my device up as it goes into recovery.
Kindly help as soon as possible.
Thank you.
If you wipe the SYSTEM Partition, then of course that no OS is installed. Like a Hard Brick. Good Job...
So I just rooted my S6 for the first time, and I'm not very experienced in rooting. I used ODIN to download, and did as told in the website here at galaxys6root.highonandroid .com/galaxy-s6-root/how-to-root-galaxy-s6s6-edge-on-android-6-0-1-marshmallow/ This meant my phone has a TWRP custom recovery but a custom one made by ManhIT, and I was successful in rooting, just that each time in recovery I do a system reboot, it hangs there so I do a force reboot which leads back to the lock screen just alright.
Then I wanted to download Xposed Framework, so I followed this tutorial to download it on Marshmellow 6.0.1: android.wonderhowto .com/how-to/install-xposed-framework-android-6-0-marshmallow-devices-0166278/
youtube .com/watch?v=B3qbY2CWz5M
I did everything, downloaded Xposed Framework for ARM64 Marshmallow devices but had to find the latest version, v85 for it and this is where the problem started. I went to TWRP recovery mode, and went to flash the xposed framwork zip, and clicked system reboot (of course it hanged, so force reboot), and since then it always has been stuck on the Samsung logo screen. I went back to recovery mode, did a factory reset, wipe all data, format data, and it still gets stuck on the logo screen.
Please please please please help!!!!
UPDATE: A possibility of this problem is due to having "No OS Installed".
what I would do if I were you is:
1. Smart switch emergency initialization to restore phone to factory fw with sn of the phone (upper right corner in SS menu) (connect phone only when you are asked, otherwise it will say your device is not supported)
2. flash CF autoroot for that model https://autoroot.chainfire.eu/
3 flash TWRP downloaded from https://twrp.me/devices/samsunggalaxys6.html for that phone model
and see what would happen (offcourse I would check after each step if the phone can boot)

I fixed it already! I think what it was in the end was the lack of OS. Should've backed up my data before doing anything funny. Installed my OS again and bam my phone is up and running again :good: (had to delete the URL from this reply as I'm just a junior member)
Hello,
For whatever reason, my samsung s6 edge doesn't work now. Everything was fine until yesterday. The device stay stuck on Samsung logo. I can't reboot the device in safe mode, the "installing system update" tell me "no command", and from the boot menu (I guess it is), the Wipe Cache option not work either.
I don't mind to loose the phone, I juste want to get back my photos / video , contacts and agenda (sync on the phone, not with a google account)
I'm an Android Developer, and I've tried to use ADB on first step but the device can't boot on Android so...
Do you know a program or something to help me troughout this ?
Many thanks
Louis

The "installing system update" and "no command" are associated to stock recovery, and the screen that shows the "Wipe Cache" option IS stock recovery, not a "boot menu". How can you say that you are an Android Developer if you don't know what android stock recovery is or looks like?
Your OS has become corrupted for whatever reason, you'll have to boot into download mode and flash the stock firmware via Samsung Smart Switch(smart switch also might help you recover your data) or flash stock firmware via Odin. If you use Odin to flash the device, make sure you flash the exact same version of firmware that you had on the device before this happened, as long as what you flash is not an upgraded or downgraded firmware, it shouldn't wipe your data when you flash it, the data "should" still be there.

Thanks for the answer. It's seems like Smart Switch no longer support "Software update and inisialization". So I should use Odin but I don't know with version of the firmaware I've use.
