S6 boot loop help

Phone started boot looping on stock firmware late last year. My wife bought another phone and I haven't been able to get to it till now. Warrantee void due to tiny crack. Wipe cache and factory reset did not work.
I tried loading stock rom upgrade to 5.1.1 using Odin3 This was successful. Still boot loop. Shows Samsung Galaxy S6... turns black for a second then shows Samsung Galaxy S6... in a loop. I guess it is a hardware issue? Anything else I can try?
Of note.. everytime I boot into recovery it says "installing system update..." Then. "no command". Then it goes into recovery.

Try this:
1. Boot to recovery.
2. Do a factory reset.
3. Reboot to Download mode from recovery mode.
4. Reflash newest stock rom.
5. Let it auto reboot and see if it still boot loops.
Or try this:
After step 3 reflash stock rom with pit file.
If that doesn't work then I have no idea.
You can also try flashing TWRP and wiping everything (system,data,internal,cache,art) and then flashing a new rom.
Oh and my friend two days ago dropped her phone on the concrete, and her phone started boot looping. She couldn't even get to recovery or anything. She dropped her phone again (her idea, don't try this). And it booted to android without any problems!
Seems like something was shorting the motherboard (?).
Good Luck.

I did as you said above twice already. (without pit) I will try TWRP next. Would flashing a new kernel be helpful?

TWRP keeps failing with ODIN. Will it not work with 5.1.1? Or am I missing something. I'm using the AP button, is that right?
Thanks!

what was the stock firmware you flashing, 5.1.1 or have you flashed 6.0.1 already ?

I'm really in the wrong section. I have an ATT phone. There is no 6.0.1 yet for those. I think my phone is not recoverable.

Flashing stock rom for note 5 marshmallow sprint

I tried rooting my note 5 sprint but got stuck in a bootloop but was able to flash the marshmalllow stock rom back on the phone. I am stuck in a bootloop again except this time odin is not responding to the stock rom. I tried odin 3.10 and 3.09 with the same result. I tried different usb ports and nothing. I can't even get the file for the stock rom to show up in the AP box. Does anyone know how to fix this? Also, can I flash lollipop back on to the phone instead of marshmallow? Thanks.

So you are able to boot back into download mode? How about boot to recovery?

I have the same problem. I have a sprint galaxy note 5 with android 6.0.1 installed. While trying to perform a root using twrp, I completely wiped everything out. Is there any way I can go back to the stock rom from here? I can still use odin and and I have finally mananged to put the stock recovery back on by using either "CF-Auto-Root-nobleltespr-nobleltespr-smn920p" md5 file or "N920PVPU1AOGD_N920PSPT1AOGD_SPR----STOCK+TARBALL" md5 file. But from here Im at a dead end. I tried to do a "wipe data/factory reset" from the factory recovery but receive an error msg stating "dm-verity verification failed." Please help. Thanks
Also it appears when I press and hold only the power button, it takes me to the factory recovery screen.

Stuck on TWRP after flashing it from ODIN

Hello guys. I recently flashed TWRP on my s6 using Odin. The first time I did it, it said that I successfully flashed it but I had autoreboot ticked, so I tried to check if my recovery has changed but it was still the stock recovery. So I tried to flash it again now without the autoreboot. It got stuck to the downloading screen even though odin has already finished. So I tried to force shutdown the phone. I tried to go to the recovery again and it was successfully flashed. I installed a new Custom rom and the Gapps (made sure I wipe everything before flashing), cleared the cached and tried to reboot. But to my surprise it was stuck to the TWRP. When I try to boot to system it's just stuck on the Galaxy s6 powered by android.
I'm sure I had the right trwp file and such but I might have made a mistake somewhere. I don't really know. Help guys?
My phone is the Canadian version G920W8

what ROM are you trying to install?
did check if your device is supported before flashing?

GalaxyS8+ SM-G955F: BRICK (Only official released binaries are allowed to be flashed)

My device has been bricked after attempting to root the device using Odin. (Samsung Galaxy S8+)
The device is stuck in a bootloop with the following accompanying error message in red on the boot screen:
"Only official released binaries are allowed to be flashed"
Here is what happened:
I flashed TWRP using Prince Comsy Odin. (The only Odin that actually works on the s8+)
I then booted into the TWRP recovery.
I followed a set of instructions, clearing the Cash and wiping
I restarted once then booted back into TWRP using Vol-Up + Power + Bixby
I was preparing to install Magisk & "no-verity-opt-encrypt-5.1" according to instructions to complete the root.
After installing "no-verity-opt-encrypt-5.1" with TWRP, the system rebooted and i was stuck in a boot loop.
I then got the error message in the bootloop "Only official released binaries are allowed to be flashed"
Since then i have not been able to successfully re-flash TWRP.
I now cant enter TWRP recovery boot using Vol-Up + Power + Bixby anymore
The bootloop is about 2 seconds long and too short to enter TWRP recovery
I can enter download mode and thats all
I have gotten the EXACT official stock ROM for the galaxy s8+ in South Africa with the carrier, Vodacom. (XFV-G955FXXU4CRL4-20181228165540)
If i flash with any official Odin version, it either fails or doesnt do anything for hours...
If i flash any Official stock Rom using Prince Comsy Odin then i do get the whole process of flashing with stock firmware being successful with the result saying "PASS".
The phone then reboots and i am still stuck in the same loop saying "Only official released binaries are allowed to be flashed"
This is after countless times and hours and hours of reflashing successfully with Official stock rom
I still cant get back into TWRP to do any partitioning or formatting or anything
I really don't mind if i lose all of my data and format the phone but PLEASE can you help me get my phone to work again..."?
Do i need to wait 7 days for the official flash to work?
Is there a way to completely wipe my phone without requiring going into Recovery mode with TWRP? Since i cant get into that state anymore either because of the Error Knox block or because of the Loop being too fast.
Please, please, PLEASE....please help me get my phone to work again...
Sincerely,

I know that Odin 3.13.1 works on the s8+ G955F as I flashed the latest BTU stock yesterday so try that version. I had a similar problem with the G950F and after flashing the files I booted into recovery mode and did a data and cache wipe and the phone rebooted. Flashing a stock rom should have wiped TWRP from the phone.
Reflash your rom or a later one, don't forget to take the tick out of the auto reboot box in Odin, boot to recovery and wipe everything and hopefully you will be good to go. Rebooting on mine took around 35 mins or so when going back to stock.

Odin says it flashed succesfuly but phone still doesn't boot

Hello, some days ago i found a Samsung Galaxy Ace Style (SM-G310HN/heatnfc3g) and i decided to mod it, i installed TWRP via Odin and all was ok, but when i tried to install CyanogenMod 12.1 it didn't work. Since it didn't work, i decided to flash stock ROM. It worked once, but now it doesn't work anymore. I suspect it's the PIT file, because when i reflashed stock ROM another time with a PIT file now it doesn't work anymore, let me try to explain:
When i try to flash anything (Stock ROM or recovery, custom or stock), it... doesn't, Odin says it flashed but when i reboot to recovery or reboot to stock, it stays at the Samsung logo or doesn't flash the recovery, even if it says that it flashed. What should i do? Is my phone bricked? How can i unbrick it if it's bricked?
