What does RPMB fuse set mean? - Samsung Galaxy S10 5G Questions & Answers

Good morning,
I decided to boot into download mode today. When I booted into download mode, there is a text on the top right of the screen that says "RPMB fuse set". What does this mean?
Thanks

Ok, so apparently I can flash the Sprint bootloader to the S10 5G and root it like a normal S10 5G from Sprint. The RPMB fuse set looks like it means that a different bootloader from a lower version or a different carrier will flash successfully. I tested it out and I have successfully obtained root and TWRP.

Btw, this is running off of a T-Mobile G977T, in case anyone was wondering, but it could work for other devices.

im on sm-g975u...and it seems i am fused to version 5 of my bootloader as i cannot downgrade to version 4...it tells me sw rev check fails cuz im on binary 5 and trying to download version 4...so i believe the fuse set is what binary ur fused to..?

Hmm, do you have an unlocked bootloader? Also, does RPMB show Provisioned or something else?
EDIT: You cannot downgrade to a version with a different bit, you must downgrade to the same bit version.

I am curious as well as to what the RPMB is and why it's provisioned ..
I've got SM-N976U carrier unlocked and bootloader unlocked rooted. I've flash 20 or 30 different things over and over to this device and only today have I seen this.

Software status : Modified

Anyone have this on the fastboot screen. My phones stock, only 1 hour old
Yes mine showed this 2. Said something about a counter =2 also

same here
Mine just says unlocked I have custom ROM as well
Mine just says Unlocked (status 3), but not Modified. I haven't installed a custom recovery yet, but I am rooted.
This message pops up if the software is rooted or changed somehow with the bootloader being locked. My guess is that since Motorola does a firmware flash hardware-wise, with the bootloader being locked, it triggers this message. If you unlock the bootloader, it goes away.

Will Root be available for the ATT variant

Just like the title says
Do you guys think the ATT S6 Edge variant would be root able? I'm trying to decide if I should just over to T-Mobile and have less coverage for a more friendly rom experience or stick with ATT and pray to the gods for root /unlocked bootloader.
Have to wait and see if the guys that got their phones today have locked bootloaders. Ive been waiting for someone to confirm this all day
My phone arrives Wednesday, and even if it has a locked bootloader, it can still be rooted (see below, S5 is locked and rooted), but I'm still curious about being able to root this thing.... Has the AT&T Note Edge been rooted? Haven't found anything saying it has yet, so that puts added pressure on finding out about this phone, theoretically
I have my Edge... The recovery log says it is bootloader G925AUCU1AOCE. Isn't that the same as the G4?
Any one been able to validate this yet?

[HOW TO] Flash U1 firmware to U device

First of all, thanks to Raymonf (I dont know his XDA Username) for making these Odin files. This new version of modded Odin allows for flashing custom and official tars AND also compressed binaries, which Samsung will be using in all Odin firmwares from Oreo on.
Oh and doing this doesnt wipe data if you do exactly what I wrote below.
1. Download your devices firmware from below
2. Enable USB debugging by going to settings > about phone > software info > click build number 7 times and enter your password
3. Open command prompt on your PC and type adb reboot bootloader
4. Open odin and select the AP, BL, CP, and HOME_CSC file in their corresponding locations
5. Start it
6. You are there!
To go back, do the exact same thing with the U firmware files!

Thank you for this. In all of the download mirrors for the s9+ the free download is unavailable. Is it asking to much to upload to a site that will offer free downloads?

The modded/patched Odin has the model-ID and SHA hash check disabled, therefore allowing you to flash an unbranded "U1" firmware onto a branded "U" phone and vice versa.
As of now this works on most US Qualcom (QC) models, but an increasing number of international Exynos (EX) models now include a new RMM security which prevents this kind of cross-flashing unless you first disable the RMM, by flashing an RMM-Disabler package through TWRP.

Probably gives better chance to root huh?
What I'm not clear on is: after I flashed my factory unlocked s9 to the VZW U firmware to see if I could get video calling to work (it didn't) then flashing back to what has been described as stock U1 ARBG firmware, in my about phone it still says VZW/VZW/XAA. Is this set by the SIM. Will this only change when I put a different carriers SIM card into the phone?
Question, before i dive in...
My UICC is locked to Sprint right now (damn 50 day limit) and I was wondering, if I flash this U1 rom, would I be able to edit the APN? Has anyone else done this?

That's correct, the unbranded "U1" firmware sets the carrier parameters based on every different carrier sim card inserted.
Don't worry about the VZW/VZW/XAA, for all intended purposes the phone acts as Verizon phone.
It's just a flag, but if you can't sleep over it then do this while rooted:
adb shell su -c echo "VZW" > /efs/imei/mps_code.dat
adb shell su -c echo "VZW" > /efs/imei/omcnw_code.dat

Flashing the unbranded "U1" firmware will neither unlock the network nor the APN settings if you keep using a Sprint sim.
On the other hand, if you unlock the network and insert an AT&T or Tmobile sim then you should be able to edit the APN, but then again you don't have to edit it because it gets set automatically based on the type of sim inserted.
Thanks a lot, quick question, i have an at&t "U" model, manage to install the U1 software (wanna get rid of all the at&t apps), everything its working just fine, but when an update comes to the U1 model, can i install it the regular way on odin, or do a need to follow this steps again??
here's the link i use from another post to dowload the system a bit faster: https://androidfilehost.com/?w=files&flid=257047 greatings to the author.

Wait do you have the same XXA unlocked model variant and tried flashing it? I'm also assuming that YMMV means "Your Model May Vary"..

Your Milage May Vary. I have a factory unlocked S9. When you flash firmware there are risk, don't hold me accountable if your Knox gets tripped some how. People hose their phones in flashing accidents then say someone gave them wrong info.

I wouldn't blame you lol, yes I know there's a risk. But you have stated earlier that you flashed a firmware and it didn't trip knox, so I'm wondering if you flashed a carrier firmware "U" on your SM-G960U1 device..

I'm glad to report that after flashing the Sprint firmware on my unlocked S9+ worked no issues and knox was not tripped. Now I've noticed that even though the Sprint splashscreen didn't show up at boot, while in setup the phone did detect the exact carrier I was on (Boost Mobile) and the phone showed the Boost Mobile splashscreen upon reboot and all the Boost Mobile apps as well as some bloatware loaded onto the phone as if it were a phone I purchased through them.
So if I flash my tmobile device to the u1 firmware can I then root my device and put twrp on it?
Is any root method available for the t-mobile version?

Galaxy Tab A 8.0 2018 SM-T387V OEM Unlock

Heya,
I just recently got a hold of this tablet a few days ago and looked for a OEM unlock switch, which obviously wasn't there, both because it's a Verizon variant, and because it's a snapdragon variant. I've been researching for awhile and found combo files to unlock the OEM switch for this model, but everybody seems to get this model confused for some reason. I tried flashing one using odin and got a SW REV check failed [Boot]Fused 2 > Binary 1. I'm guessing I need to downgrade this tablet back down to android 8 since I updated it to android 9. Before I do that, I want to see if flashing the old firmware will be a waste of time or not and to see if there is a combo file or ENG boot file I can flash to get OEM or at least root unlocked. Something to get rid of all this Verizon bloatware and get rid of the Verizon boot animation with just a stock one. Hope I get a decently fast response.

theres not really any support for that tablet.. u can flash combo but so ur aware its not possible to downgrade.. u need a newer combo firmware that is same rev as the firmware ur on..
there is no eng firmware from what i can tell.
I've found several sites that have the firmware I need, but they're all locked behind a paywall. They're only like, $3 but I don't feel like entering my card info on these sites. Might just bite the bullet and get me a throwaway card. My baseband version is T387VVRU2BTB2. REV0.4. maybe somebody can find one for free out there. If not, I'll probably just pay the $3 and stop being stingy with my money.

I'm also looking for some firmware to possibly bypass FRP on my SM-T387V. Did you end up fbuying the firmware? Did it work?
I have a sm-t307u and while not the same device I'm unable to flash combo files due to a new token security measure. So, no OEM Unlock, no bootloader unlock, and no combo flashing in ODIN.

Is it possible to change S20 FE G781B to G781U?

I was wondering if it is possible to flash G781U firmware on G781B since they have the same specs.
would love to hear what you think (or know).
Thanks
I'd keep the B model as it is as it can have it's bootloader unlocked. if you're taking that phone to the states someone would gladly buy it off you as is.
if you wanted updates after moving they could easily be manually downloaded and flashed. if you concerned about frequency bands then maybe there are ways to tackle that.

Thanks for the reply, I know its better to keep it that way but if I wanted to change it anyway, will it be possible or would I just brick the phone?

not sure to be honest, I suspect that the existing bootloader would generate a fail error before or just after you started but I can't say for sure.
if it did fail after starting to flash you'd need B firmware on hand to make it useable again.
Trying the same but switching from 781W to 781B. Had no success so far. Odin is failing to flash. At least so far I did not brick the device. Any advice is welcome

tried, but so far without success. I'm missing the "OEM unlocking" option that is stated in the manual. Trying now to update to latest firmware. Maybe this will enable the unlocking option.
hm... I just learned that there may be no OEM unlocking option on my snapdragon device. There really is a lot to consider... Somehow OEM unlocking does not work on snapdragon devices from north america. In latin america although this might work. I don't really get what the point of all this is. [some sauce]
edit: maybe it is possible to unlock it through fastboot, but so far i only get a command not found error when using ´´´fastboot oem unlock´´´

Yeah, from what I understand devices with U at the end of their model number are missing the OEM unlocking option. I think its stupid to only block the option to some of the world, I mean either block it completely or dont block it at all.
Maybe it is possible to change your model to W and then unlock it, I im not wrong you are supposed to be able to flash W firmware on your U device without unlocking the bootloader.
Just make sure you download firmware with the same binary number in the baseband (the fifth number from the right)

Unlike the original poster I am trying to go from SM-G781W to SM-G781B (or anything else that has german language).
To my understanding Samsung does this as the carriers in North America are requiring it, but not sure why.
