What mean "SPU 5" in dowload mode ?

[Android Central Question]

I see other phone with SPU 5 (valid) but no one written with just SPU 5 in red character like my galaxy s20fe5g!

Welcome to Android Central.

Did you look this up at all? Just curious because I would rather not tell you things you already know. In the meantime it appears to be related to Qualcomm, the folks that make the Snapdragon chip that is in most of Samsung's devices. It stands for Secure Processing Unit. Now why it would be in red on your device is something that perhaps Samsung or Qualcomm could answer but I found this long paper on it which you can read if you'd like to know more.

https://csrc.nist.gov/CSRC/media/pr...ram/documents/security-policies/140sp3549.pdf

My guess would be that your device has been rooted or had the bootloader unlocked which is the first step to rooting and this security protocol or whatever it is, has been broken. Just a guess but considering it is related to security and the Qualcomm chipset, that is the way I'm leaning.

Did you buy the phone new, used or refurbished?

Welcome to AC!
Download mode is only flashing stock or moded Roms .

If your not familiar with this you can't automatically assume your hacked

Just one operation i have tested is to flash a oem firmware from samsung with odin the operation was succes but i think its just the frmware number has changed! The firmware in system parameter is not updateable!.

All phone i have see was written spu 5 (verified) there are just mine that it written just spu 5 in Red

 

[Ktmbooster]

Also in the recovery log when i factory reset it write nothing in the log i think it just wipe the data!

 

[mustang7757]

Im not sure what spu 5 is in download mode but the ones you concentrate on when on stock firmware is
Knox 0x 0
Biniary official Samsung

You would need to ask xda Forum but being in red could mean its the way older Samsung were as you see my screenshot of my fold 4 in blue .

I do enough of Odin flashing stock firmware over the years to know dont worry about .

Hi Ktmbooster,
I have a Samsung Z Fold 3 and my phone too is displaying this SPU5 in Red in Download mode. I cannot seem to find anything on the internet which indicates what this means. Somebody seems to Know alot about the activities on my phone too man - I get what you're saying. Did you ever get to the bottom of this or find out more?

Welcome to AC!

Thanks for your reply. This is what my phone says in Download mode:
RPMB Fuse Set
RPMB PROVISIONED
CURRENT BINARY: Samsung Official
FRP LOCK: OFF
OEM LOCK: ON (U)
KG STATUS: CHECKING (00)
WARRANTY VOID: 0x0
QUALCOMM SECUREBOOT: ENABLED
RP SWREV: B4 (4,4,1,1,1,1,1,1,1)
RP SWREV: K4 (4,4,4,4) S4
SECURE DOWNLOAD: ENABLED
SPU:5
HDM STATUS: NONE

I assume Knox 0x0 is the same as KG Status? If so why does it say Checking (00)

Sorry to sound Noob but I just feel like someone has remote access to my device. Someone seems to know the activities of my phone. I have factory reset it to no avail.

Hi yeah those other things you mentioned I'm not sure but download mode is only for installing custom ROM or Samsung official firmware with Odin so someone would need your device in their hands to do something there and nothing suggests it's been altered.
Also go to settings>about phone>status information scroll down does it say Phone Status >Official?
