Samsung S7 bricked ? stuck on TWRP logo

@aibd

Are there any clues appearing on the Download mode screen?

No red lines, no text information about something goes wrong.
Just the splash screen of e follow 30 mn after by TWRP

But I am asking about the Download mode screen – this is the green coloured screen – it is expected to be stable. Is Download mode actually unstable?

It usually tells us if there are any locks applied it can inform of other issues too.

On the download screen there are in the right up corner :

ODIN MODE     (red)
DOWNLOAD SPEED: FAST    (red)
PRODUCT NAME : S0-G930F         (white)
CURRENT BINARY: Custom         (white)
FRP LOCK: OFF         (white)
Secure Download : Enabled         (blue)
WARRANTY VOID: 1 (0x030c)         (green)
RP SWREV: B:8 K:6 S:7         (green)

And that’s all. At the end of the flash I have to reboot the phone. No more messages.

Here I wrote something about the S7, maybe it helps.
Plus the only Samsung devices I could not flash stock or custom, had hardware failure.

Samsung Galaxy Tab A7 10.4 2020 (Wi-Fi) flashing help needed

If you decide to use Odin, just a few things to watch out for: Stop Odin from AutoReboot You can do that every time you start Odin, in the Option tab(next to the Log tab) or open the Odin3.ini and change it there for good: [APOption] RePartition=0 AutoReboot=0 FResetTime=1 FlashLock=0 TFlash=0 NandErase=0 Keep an eye on the Log, as connection issues show up there, which are often missed [ODIN-Stock-flash_S7_badUSB] If you ever have to install a Stock ROM, there are single-part and 3/4/5-par…

@Ghisbar

I try to to reinstall stock SamsungOS without success (sbin issue)

As said by @make-nz Odin to Stock ROM is a good form of test, both for the device and the PC.

Perhaps you can share any Odin error / issue.

Thank you for helping me.
I did a new flash test of the rom.
Below is the ODIN log.

I realized that my smartphone’s bootloader is in 8 and that I was trying to flash it with a ROM whose bootloader is in 2.

After loading the correct ROM, it’s ok !!!

Next step is to load e os !

Only for information

One of my S7 (herolte) SM-G930F works perfectly with TWRP 3.7.0_9-1 + UNOFFICIAL LineageOS 20.0 for microG (A13).

The other S7 (herolte) SM-G930F works perfectly with e-rocovery (e-1.18-t-20231211, e-1.19.1-t-20240111 and e-1.20-t-20240224 + herolte.zip build by @ronnz98
