S8 (sm-g950f) wont boot, reset, wipe and is stuck - General Questions and Answers

Hello,
My phone(Samsung galaxy s8) just had a crash and is stuck on the blue screen with "Installing update". After several seconds the screen goes away and boots straight into the recovery mode.
The log that i see in the recovery is :
Fail to open recovery_cause(No such file or directory)
Failed to mount /efs
Unknown volume for path /odm
dm-verity verification failed
I tried to install the stock firmware (I cant link to the webpage but im 100% sure its the correct one) but it wont boot and goes to the "Installing update" again and after that to the recovery.
I tried installing twrp but it wont install due a FRP lock. i read that you should wipe your data and factory reset. Also tried that but again no succes.
Can someone please help me.
Thanks in advance

I'm going to take a guess here, you had the device rooted and then you tried to apply an OTA stock update while the device was rooted? Tyically, stock OTA updates can't be applied to devices that have been rooted because the updates require the device to have an unmodified system partition(no root) and they require stock recovery instead of custom recovery. There are "some" devices that can apply stock updates while rooted, but those are few and far between.
If that is what you did, you need to do some searching for repairing failed OTA updates on rooted devices.

[Q] Moto G keeps on rebooting and updating

This morning my device was asking if it could do a firmware (?) update. I confirmed and of that moment it keeps on rebooting and trying to install an update. Whatever I try I can't get through the loop of updating/rebooting. I thought that maybe via the bootloader (which is working) I can install a new ROM or restore the stock firmware, but nothing is helping. When in the bootloader, the PC can find the device although it is connected (USB connected)
What I see when it's rebooting:
Install untrusted package?
this can not be undone
- no
- yes
- go back
CWM based recovery v6.0.4.5
E: invalid command argument
finding update package
opening update package
verifying update package
e: failed to verify whole-file signature
e:signature verification failed
what ever I choose it goes to the next screen:
root access possibly lost. Fix?
this can not be undone
CWM based recovery v6.0.4.5
E: invalid command argument
finding update package
opening update package
verifying update package
e: failed to verify whole-file signature
e:signature verification failed
Installation aborted
rebooting...
...and it starts all over again...it boots normally but after 10 sec it reboots again...
Has somebody any idea what the problem is and how it can be solved. As it is, I can't do anything with this mobile.
Thanks for your help!
Your post says 'PC can find the device' but I assume you mean 'PC cant find the device'.
So you have a custom recovery, are you also rooted? A custom recovery means an OTA update wont work. You need the stock recovery. I assume the custom recovery has caused the update to fail in such a way that it just keeps rebooting.
Can you manage to get into CWM via the bootloader (ie choose recovery from bootloader options using volume buttons), if so then wipe cache as this will remove the update file and you should be OK then.
If not then I think you need to get the phone seen by the PC when in the bootloader as otherwise you are stuck. I assume at some point it was seen by the PC for you to install CWM?
If running Windows do you still have the drivers installed (I run linux so Im unsure what you would need). I assume a 'fastboot devices' shows no device at all from what you say?
If you can get fastboot working you can then flash back the stock recovery and this may then allow the update to get past the point its failing at, it may still fail but then you can take it from there.
But first try getting to CWM via bootloader and wiping cache and then reboot.

Thank you for your quick reply.
Correct. I mean the PC can't find the device. However via Motorola Device Manager it can.
Yes the phone is rooted
I can't get into the CWM. If I choose recovery from the bootloader, it reboots normally...and the loop starts again...
will try the fastboot.
How are you trying to choose the recovery option from the bootloader?
You MUST select recovery option using the VOLUME UP button (volume down to move between options and volume UP to pick an option).
Do NOT use the power button.

This is very good advice, regarding selecting recovery from Bootloader....
it happened to me, for days I was puzzled, even after flashing stock recovery, 4.3 Recovery, I could not enter Recovery, until I actually read what was written in the BL screen.
Use Vol down to scroll to option, then use Vol up to select that option......(Recovery)
As you say, important not to use power button.....as would come naturally, and its what we use in Recovery......
but not in Bootloader!!!!!!
I panicked so much, but just be calm!!!

If you are rooted it will still fail to update. You are best off just clearing cache via recovery. Or delete zip file (if you get booted up) from /cache using a root file explorer.

motofastboot is a modified fastboot that allows larger images to be flashed. Normal fastboot will work fine for recovery AFAIK.

It's just that mfastboot is recommended by most devs, including Paul O'Brien and flibblesan, on Modaco, and loads of ppl here on XDA, for flashing FW to Motorola devices from BL, so I'd go with it, as it is widely available on either Modaco or XDA.
I don't think an OTA will fail due to root, just if you have modified or removed any system files, or are using a custom recovery.
I think you have to re-root after OTA is applied.
Rooting at 4.4 is easy with Chainfire's SuperSU CWM flasable zip, as explained by flibblesan here:

Easiest way to root would be to boot a custom recovery and flash Superuser through that.

superSU updates /system/etc/install-recovery.sh
This file is checked for a hash by the script (updater-script) that installs the update. As the file is different then the script bombs out with an error.
I know this because I am rooted and I by mistake attempted to install the OTA when I got the OTA notification. It failed.
There is a line in the updater-script like this:
apply_patch_check("/system/etc/install-recovery.sh", "b54528cf9ebba39534b768ad9108a4732e1eff4a", "99ffe4a3d0e6612e87cd3f6a62dad642094f0169") || abort("\"/system/etc/install-recovery.sh\" has unexpected contents.");
This is basically checking that file and seeing if it has the expected hash (one/both of those long numbers are the hash).
Interestingly the ORIGINAL install-recovery.sh file has these comments at the start of the file:
# File Name: install-recovery.sh
#
# General Description: This script is used to install software update for
# recovery mode after OTA update. This is modified
# from original Google code to split the code into
# a fixed program while putting the dynamic data
# into a config file.
After superSU is flashed it says stuff about superSU in it and the file is completely different hence why if you are rooted (at least if using superSU) then the update fails. Whether there are also other /system files also updated by rooting I dont know.
I dont know why superSU modifies the file, the file once modified kicks off a daemon called daemonsu. Why it has to be this file to start that deamon I dont know - but obviously there must be some reason its rooted in this way.

Thanks for that info......a bit complicated, but I get the gist of why OTA will fail, if rooted using the SuperSU Recovery zip.
I suppose, as you will be un-rooted in any case, unrooting prior to OTA is advisable, I can see that....
when I rooted originally, I used Superboot, as per Paul's Option 1
However, as per the OP, and my attempted OTA, with CWM Recovery intact, and the bootloop problem, etc, etc...and my panic, and not reading what is written in BL....
I never got to flash the OTA, and I just went ahead and learned how to use fastboot, and downloaded the American ROM, flashed it, and CWM Recovery, which works with 4.4 now, and flashed the root zip, as above, and some other zip to give back the H+ for HSPA+ logo, and now I'm happy.....
I'll never have another OTA to deal with now......
When stuff goes wrong we all learn a lot more than if it always went to plan, so its good we have learnt some new things today.
When 4.4.3 is out it'll all be easy now
Everything is working again! With AdbWinUsbApi.dll I could find my device and flash it. And with the help of this topic http://forum.xda-developers.com/showthread.php?t=2542219 I was able to restore the firmware as it was...nearly...I had a Dutch (EU) version, now it's US...no big deal.

Man....you did what I did, and ended up with US 4.4.....
I had UK Tesco 4.3, with an OTA sitting in \cache, but tried to flash with CWM Recovery, messed up, panicked, but things are good now, latest CWM, rooted with SuperSU.
There is also a CWM zip to restore your H indicator for HSPA mobile speed, as US ROM only has 3G for this, and it also modifies the cell signal bars back to normal Android width.....

I had the same situation just now. Accidentally confirmed the OTA update prompt, then the phone goes bootloop. After fiddling here and there, turns out the solution was simple. Reboot to bootloader, connect usb to PC, then wipe the cache using fastboot (fastboot erase cache). It will remove the OTA update zip file and stops the bootloop. Now I need to disable OTA update prompt.
just got the same problem!
solution that worked with me: booted in recovery, connected to pc, [left shift]+[right klick] on folder that contains mfastboot.exe, open prompt, type "mfastboot erase cache". done!
system update is now stopped

SM-G930x Retail Phone Secure Check Fail : (PIT), help please?

So I got a hold of a retail G930x and was successfully able to install TWRP and factory reset with a stock image, only problem was that I never turned off the FRP lock, and when the phone was restarted while updating SuperSU my recovery was blocked. OK, no problem, just flash a stock ROM through Odin mode right? Well for some reason G930AATT1APB5, and G930FXXU1APB4, do not seem to work. At one point I was able to partialy boot into the stock recovery, but at another flash attempt my computer blue screened and I received the error message "An error has occured while updating the device software. Use Emergency recovery function in the smart switch PC software", but Smart Switch returns an error message of "Device Not Supported". I can still boot into Download mode and attempt flashes, but I can't seem to find a working ROM for this phone or a solution to the stock Recovery issue (which is most likely corrupted by now). Any help would be greatly appreciated, thank you.
edit:
edit: so I flashed a recovery image file from ROM.G93xF.XXU1DQFM-v18.0.by.ambasadii.zip and was able to get to the stock recover screen. Unfortunately i get an error message saying "Failed to mount E: /system (Invalid Argument)
Update from external storage is disabled.

SM-G920FD Boot Loop with "No command" error.

Hi
I have a Samsung G920FD mobile phone. It's a few days now that I have the problem of Boot Loop and displaying the phrase "No command". I searched a lot over these days and tried different solutions. But I did not get any results.
I installed many ROM types by odin and twrp, but I did not get any results.
When I install the new ROM using Odin, after the restart, the message "Install System Update" appears, and it progresses to 32%. But then the Erasing message appears and the system will reset, and from then on, enter the Boot Loop phase.
In addition, these terms are written in Download mode:
SYSTEM STATUS: CUSTOM
REACTIVATION LOCK: OFF
Secure Download: Enabled
Please guide me to solve this problem! Thanks

I did before any flashing.
But after the flash, it immediately restarts and the update installation process begins.
So, if unchecked the auto-boot option, then I need to restart manually.
There is no way to shutdown in download mode so that you can enter recovery mode.
Therefore, I can enter the recovery mode only after the first restart
An important point. My phone has been in the hands of a friend for a while. After that, the problem occurred and I did not know the latest version of the ROM installed on it.
Why always happen at 32%?

Installing system update fail after Odin flash. Boot into recovery mode.

Hi,
My phone (S7) got into a boot loop for no apparent reason. I noticed it was a bit hot and it froze a couple of times so I rebooted it and after that it was stuck in a boot loop no matter what. I then tried "flashing" the latest firmware with Odin3 to fix it. Everything was fine in Odin but after the phone rebooted, it couldn't finish installing the patch... It showed an "error!' screen then booted into Android Recovery with these logs:

Hello, this problem is very common for people that root their phones if you get drk error then there are 2 methods to solve this
Method one : easy
Just flash cf autoroot with odin download the file for your phone and flash it in ap
You may get stuck or get bootloops in splash screen or red errors just wait patiently until rom boots
Method 2 : for if you want no root (ota still impossible)
Flash twrp with odin, then download the no verity file
And move it to your phone, in twrp tap on install and select the file
https://build.nethunter.com/android-tools/no-verity-opt-encrypt/
Just download the latest version of the file (6.0)
Now wait until rom boots
-----------------------------------------------------------------------------------
Please donate and like if you think i deserved it,
If it didnt work you don't have to do it
Happy flashing and good luck
Dont forget to update me after following the steps
I'm a total newbie when it comes to phone flashing, I have a few questions. If I decide to use autoroot, is there a chance for a brick? What could go wrong? I think there's no turning back from rooting a device, right? I don't want to lose my data.
Also, I can't seem to make TWRP work because when I plug the phone to the pc it doesn't recognize it and I can't access it whatsoever to put the files in there, even after installing the drivers.
Thanks!

I'm a total newbie when it comes to phone flashing, I have a few questions. If I decide to use autoroot, is there a chance for a brick? What could go wrong? I think there's no turning back from rooting a device, right? I don't want to lose my data.
Also, I can't seem to make TWRP work because when I plug the phone to the pc it doesn't recognize it and I can't access it whatsoever to put the files in there, even after installing the drivers.
Thanks!

Flash the stock firmware again but from download the firmware from Samfirm application. Please use the HOME_CSC too or your device is wiped. If you need the firmware just post modelnumber or name idk and CSC code and i can post a link with the firmware for you. TWRP can't mount /data and you will need to format your phone with means you lose everything.

Hello, this problem is very common for people that root their phones if you get drk error then there are 2 methods to solve this
Method one : easy
Just flash cf autoroot with odin download the file for your phone and flash it in ap
You may get stuck or get bootloops in splash screen or red errors just wait patiently until rom boots
Method 2 : for if you want no root (ota still impossible)
Flash twrp with odin, then download the no verity file
And move it to your phone, in twrp tap on install and select the file
but i have done factory reset so how to enable oem /unlock bootloader to flash via odin

Help J330F Not booting(recovery:error failed to mount efs)

Hi there
I have the J330F/ds phone.
It won't boot.
ODIN mode says its J330F OEM&FRP LOCK=ON
Binary: U3
I tried latest pie stock rom. It boots into recovery mode only with errors E: failed to mount efs(invalid argument)
dm verity verification failed
and some failed to clear bcd efs(invalid argumenet)
I tried Nougat stock rom too. In recovery mode it gives me failed to mount efs and dm verity failed
After I do factory reset/clear cashe the phone boots to the samsung logo and it stays there.
Same thing happens when with Factory Binary. It boots up to the clock gears and it just sits there.
Since I have OEM and FRP lock on I can't install TWRP
Can the efs error be fixed with efs if someone has it for U3 binary. I think that that error causes the stuck on logo. and it won't even let me boot factory binary???
If someone could help I would really appreciate it.
Fixed it!
I was able to fix it. First I flashed efs.img tar file that I found on the internet.
I was able to boot into combination firmware and I flashed 7.0 stock via ODIN.
I flashed only system.img boot.img and sboot.img. And it worked I was able to remove FRP and OEM lock and they are both off. I tried pie stock and it did boot up and worked but when I factory reseted via menu on the phone the phone was stuck on starting screen and had the same dm verity error. I was not bothered with trying to root it and flashing twrp and the skip dm -verity tar. I just went back to 7.0 and factory reset works just fine there.
The problem was efs corruption or missing altogether. And dm verity can be fixed with root twrp and the skip dm verity tar file which I didn't do but it should fix that too!
