I've come into possession of a device with something displaying in Download mode that I've never seen before - on any Samsung device. All of the threads that I've found on rooting or BL unlocking have been closed. Is there anyone still around who knows enough to help me reverse engineer this? @Acoustichayes @BotsOne @elliwigy

just saw ur message lol.. if u dont mind me asking, whered u get it from lol..
either way, you have an S8 with eng mode enabled. Typically on newer phones there are eng certs or "tokens" that can be flashed to the device enabling eng mode and allowing custom firmware.. the certs are pretty much impossible to find unless ur in good with samsung or pay a good amount of money for..
to my knowledge, they are device specific also. meaning no way to pull the cert/token to use on other devices..
i could be wrong but based on @partcyborg coming across a similar eng mode that is what i have learned lol

It's cert based? Damn. Thought maybe it was another bootloader partition that isn't in the BL Odin tar. I didn't think the cert carried anything other than the IMEI. But I guess that's a foolproof way to do it, since it's coded according to the CPID. And no, they can't be read from the device. Guess we're stuck...

Hello guys,
I own a SM-N960F ENG MODE: DEV DEVICE which is in "custom binary blocked by frp lock". I have tried to flash all sorts of firmware including the latest stock version CSDE to no avail. ODIN passes it successfully but when it tries to reboot it goes again into "custom binary blocked by frp lock"
Hope you might shed some light...

It sounds like the binary being referred to is a partition that is not touched by a standard firmware flash. Have you tried flashing the Combination/Factory firmware?

Ive seen guys mention the error but I've never seen it so I'm not sure. Sounds like it's frp locked so i would search on a way to bypass frp on your device. They've changed a bit and i haven't read up on the newer devices really yet I'm not ready to upgrade

iBowToAndroid, thank you for replying. I tried this specific combination through AP section of ODIN:COMBINATION_FAC_FA81_N960FXXU2ARK4.rar. ODIN flashed successfully but phone is in continuous boot loop stating "Boot Image Signature Check Fail!!!. Reboot to avoid warranty bit set!!!" Combination ARK4 is based on Oreo 8.1 meanwhile device had stock Pie 9.
What do you mean exactly when you say Combination/Factory Firmware if you don't mind...

5th digit back is your bootloader number you are flashing a older boot loader than what's on your device

No, it's not actually FRP locked. It just means that the FRP security is enabled. If he did a factory reset from the Recovery menu, then yes, it would actually be "locked". But he has specifically stated that his device is bootlooping - so how would he do a bypass anyways...?

Huh? Dude, that makes no sense. First of all, he stated that it flashed successfully. And regardless, the newest bootloader for his model is 2. So it's impossible for his device to have anything newer.

That is exactly what I meant - a Combination firmware. It sounds like whatever changes were made to put it into "Eng mode" prevent it from accepting a stock retail device flash - or at least prevent it from booting on that firmware. Sounds like you might need to look into obtaining a different device

Hello, I just came across a S8 International G950FD phone with this option on Download screen. Not sure if it is worth anything to anyone before I use it. I wonder what this mode means on a Exynos Samsung, because these already allow the bootloader to be unlocked. Anyone know? I could see the G950U utilizing this because the bootloader is locked on the US phones, but unsure what this would benefit on a International model G950FD. Maybe it just means that this S8 does not have RMM or KG State to be prenormal? Like ever maybe, even if I factory reset.

I know this is a bit late, but I have a US note 20 ultra that also says this on the download screen. I recieved the phone about 3 months before the note 20 actually came out.

Need help asap please - SM-G935W8

So I was setting up my device yesterday and enabled fingerprint unlocking and choose a pattern unlock and written password as backup options.
When I restarted my phone, in order to unlock the phone it stated to use pattern unlock to protect fingerprint scanning after reboots (something of that nature).
Problem is for some reason I cannot figure out the pattern to unlock (I'm sure im using the one i set in place) and I cannot use my written password to unlock either, it's just by pattern.
So am I locked out of my phone and don't know what to do. I'm trying to do a factory reset to see if that'll work.
But I also flashed twrp and noticed that this model cannot be rooted so i left the custom recovery as it is. I do not want to swipe right to "allow modifications" as I heard if I do not install the right files it might be stuck in a continuous loop. So I clicked on Keep Read Only. When I try to wipe it keeps on telling me it's failed is it due to being in read only (I also don't see any of the contents on my internal storage)?
Should I flash the stock recovery with odin but I cannot find it for this model. Can someone point me in the right direction?

Cant flash anything on SM-G950U

I bought this device online and it ended up being google locked. In my efforts to still be able to use the phone, I flashed Factionary Binary onto the phone as instructed by a tutorial to remove the FRP lock. After doing this i thought i would just simply flash stock firmware, oh boy was I wrong. I have tried so many different things over the course of hours with no luck. odin fails every single time. Can anyone help please?

You should report that user he wasn't suppose to sell you a phone with the Google verification lock on it that means he hard reseted the phone instead of factory restoring the phone threw settings which then you would of been able to log in with any Google account when you did the setup wizard to setup the phone

If it's a Samsung you got to go on sammobie get the latest firmware and install it in Odin if the phone bootloader unlocked you could see if they have twrp for your device but I wouldn't suggest flashing it cause you have to get into developer settings and implement OEM unlock first or else the phone could soft brick

There is no official twrp no boot loader unlock. Flash the test firmware you have. Flip OEM unlock factory reset and flash stock firmware that's how to disable frp.

FRP Locked S8 G950U

I have a Galaxy S8 that is FRP locked.
The exact model and version is: 8.0.0/R16NW/G950USQS3CRE2
From what I understand this has the v3 bootloader and Oreo, correct?
I need some help getting this phone unlocked. Anyone care to lend a hand? I can use Odin and ADB just fine, I just need to find the correct files needed for the version I have.
Also, if I can actually get the correct files., can someone outline the steps needed to do this? I've been trying to unlock this thing for about three weeks and my brain is turned to mush with all the things I've tried.
Please don't send me PMs trying to get me to contact through other means.

Hey. Don't worry. Frp lock is a protection for your phone this occurs when your oem lock is on. To unlock it go into developer options and then tick the oem unlock option . But for now your phone locked all you can do it flash stock firmware using odin . That's the only way . I know the data ma be precious inside the phone but it be useless until phone in not booting . So ho and flash stock firmware for your device from sammobile.com
Thats all . I hope may this helps you and inform me as soon as possible.
Stay Blessed?

Yeah, flashing the firmware doesn't reset the FRP. Tried just AP, AP and BL, all five, doesn't matter. On first boot it requires the previous owner to log in. It's stored somewhere that's not touched by the flashing process somehow. Or it fails. After doing all five files on first boot it says it's installing something, gets into the 30% range, then says erasing for a bit and reboots.
Is there any way to do this?

flash a combination file factory reset from combo then flash legit bit 3 or higher firmware. The 30% failure after erasing is normal. 32% normally

Its test and diagnostic firmware released by Samsung. It is not a usable rom. You'll flash this. Factory reset from inside the settings menu. Then you can reflash official firmware. And you should be good to go unless this has been patched

So I went ahead and flashed the combination file in the first link and did a factory reset. Now when I try to flash the files I already have it fails. I'm assuming that's because I flashed a bit 5 combination firmware, and the stock files I have are not bit 5.
How do I know which firmware files I need? Do I need to do all files (BL, AP, CP, CSC) or just one? It's very hard to figure out what to do when everything I read is different.

Yea you need bit 5 files. Flash all 4. If you look at a firmware number. 5th dig from far end will be a 1-6 that's the current bit, anti rollback whatever you want to call it.

Thank you so much for the help. I'm getting closer.
I am currently downloading a file called G950USQU5DSC1. Should be bit 5. I'm pretty sure it's for Sprint, and this phone was originally Verizon. Will this be a problem? I'd very much prefer AT&T or T-Mobile, but Verizon might be OK if I'm locked to it.

verizon firmware is unlocked sim wise sprint firm probably wont work but also should setup based off of your sim card inserted.
dsc1 i believe is pie which is awesome on s8 you can change carrier also with the combination file pretty much as your doing with each personalized firmware to each carrier

I'm grabbing the file from this page: https://www.theandroidsoul.com/samsung-galaxy-s8-firmware/
How can I tell which carrier is which? I'd rather just flash the correct one off the bat. Looks like the only one on that page for the 950U that is Pie is the Sprint one. I don't have a SIM. Well, I could take the one out of my current phone temporarily if it'll help set it up correctly.
Is the process for switching carriers just flashing the CSC file? Or is it more involved.
EDIT: There is a CRK1 file that is U5 and Oreo. Pretty sure that is Verizon. Cancelled the other file and am downloading this one. Going to take a while, using my phone as it's faster than my home internet.

The CsC determines sales code and carrier setup. I use sammobile or updato.com they have all firmwares needed
Boom. It worked. Typing this on the S8. Even accepted my AT&T SIM and connected to data.
Flashed an 8.0 firmware, but it seems to be getting updates. Maybe it'll update automatically to 9.
Anyway, thanks again. Free S8 is nice.

that firmware is from sprint. something worth sharing is that all S8's designated for the US market are literally the exact same physically. You CAN flash whatever firmware you want for whatever carrier on a g950u. You will need a modified version of Odin to flash firmwares originally intended for a different phone tho. I had the FRP lock on my dads old S5 the other day, but i was able to get thru it with my gmail information oddly enough. Not sure why google thought that authenticating use on that device per my gmail account credentials was ok, but..... ok i guess.
Once you get the phone up and running, put a sim card from whatever provider you intend on using in the phone, if it asks you for an unlock code, then youll need to get one from the original carrier it was intended for or a third party paid site. AT&T has a sim unlock tool on their own site you can try.
Teh reason i mentioned that all the S8s intended for the USA are literally identical is because you can take a sprint S8 and use it on Verizon, AT&T, T-Mob blah blah provided youve flashed the correct firmware, which is either the U1 version or the bespoke firmware for that carrier

You CAN flash whatever firmware you want for whatever carrier on a g950u. You will need a modified version of Odin to flash firmwares originally intended for a different phone tho. I had the FRP lock on my dads old S5 the other day, but i was able to get thru it with my gmail information oddly enough. Not sure why google thought that authenticating use on that device per my gmail account credentials was ok, but..... ok i guess.
Once you get the phone up and running, put a sim card from whatever provider you intend on using in the phone, if it asks you for an unlock code, then youll need to get one from the original carrier it was intended for or a third party paid site. AT&T has a sim unlock tool on their own site you can try.
Teh reason i mentioned that all the S8s intended for the USA are literally identical is because you can take a sprint S8 and use it on Verizon, AT&T, T-Mob blah blah provided youve flashed the correct firmware, which is either the U1 version or the bespoke firmware for that carrier

Very good info. Thanks.
When I first booted the phone after flashing I had put my StraightTalk AT&T SIM in and it connected right away. It also started downloading and installing system updates, all the way through the Android 9 upgrade and the August security update. Pretty cool. The only thing I see is after a reboot or power on a notification pops saying that a non-Verizon SIM is installed. But that notification can be dismissed, and as far as I can see doesn't recur until next boot. So easily ignored. And there's Verizon specific bloatware. Maybe I'll download AT&T and T-Mobile images just in case. I've been thinking about carrier hopping, as I have pretty poor AT&T coverage in my area, since with StraightTalk I can get a Verizon SIM added to my plan and take my AT&T one off pretty easily.
I haven't really used the phone much yet, as I'm waiting on a case, but I'm not sure I'm going to like the Samsung skin. I'm used to a very stock Android experience, as I've only really used Motorola phones and my current Nokia 6.1. I just like plain vanilla Android. But I'll give it a shot. Already installed Nova Launcher and F-Droid.
followed everything on this thread, uploaded 5 level firmware files just fine, but now i get a "system software not authorized by at&t.." message.. any help?

Galaxy S8 bricked - Stuck in boot loop after flashing twrp

Hey there everyone,
I wanted to root my s8 (sm-950f) and when I flashed twrp my phone initially got stuck in Samsung logo. After managing to shut it down I tried to go to recovery mode to wipe everything and perform a factory reset but I can not do it. All that happens is I get to s8 screen and it reads in red on top left of the screen "Only official released binaries are allowed to be flashed" and it keeps resetting itself. I can access download mode but that's it, I can't do anything else. Currently downloading a stock firmware to try and flash it but with the free downloads it's taking its time. Any help appreciated, I really want to unbrick my phone
note: It shows FRP and OEM lock to be off in download mode, i dont even know if i'll even be able to flash a new fw. Do I just have a very expensive brick in my hands now?

This must be a international S8... Did you activate oem unlock in developer settings before flashing twrp
([emoji3590]09-09-18[emoji3590])
I'm not sure if it's international, it's most likely a Turkish version.
And yeah to your question

But you know for a fact that there's a twrp version for your device.... Not good to do these expensive phones like that without officially having all the facts
([emoji3590]09-09-18[emoji3590])
Well it's too late for that now, I need actual solutions. I also tried smart switch - it doesn't recognize the phone

On the xda thread for your device there aren't no stock roms uploaded to Android host for fast download so you can flash in Odin and start the process of twrp again or just leave it alone you have a S8 it's good money
([emoji3590]09-09-18[emoji3590])
WHEW. Flashing a stock firmware seems to have fixed the issue. Mods can lock the thread.

You going to give up on twrp

I do want to root, but I don't want to approach it without knowing all my facts, do you have any suggestions for guides for Android 9.0?

Just look in your device forum everything Is there however your device is a international cause it ends in with the F so twrp does work for your device..... You just need to find the specific one for your model once you have twrp you can install a android 9 custom rom
([emoji3590]09-09-18[emoji3590])
I had same issue as you and was pointed towards this thread may be of some use to you?

Sorry but I have a serious problem. I have activated oem and debug usb on developer option, but I can't install TWRP. I have tried with odin, prince cosmy odin, odin patched but FAIL everywhere, please help me, I just want twrp and i want to install a custom rom. thanks in advance everyone. If is a problem answer me here, you can send me a pvt message. I tried it from 3 days with the same FAILS :_(
I had this problem too a year ago but wasn't able to reflash the official firmware, but when I went to Samsung they fixed it for free even though Knox was already tripped

ok, get the firmware for your phone from sammobile.com but use samfirm or frija to download it, flash the firmware in Odin 9 time. yes, 9 times. try booting between flashes and itll go away by the 9th time. Not even kidding
9 time flashing. No chance. FRP lock is almost there.
Installed is G935FXXS6ESI4
What can i do ? Any Idea = Combination Firmware ?

not anymore. there was a patch that fixed the bug that allowed this to occur. Sammy is always right on our tails. now you need the combination firmware, which you flash in Odin as well then follow it up with the stock firmware from sammobile since the combination FW isnt really bootable (it is, but its weird lol)

I flashed the combination firmware. After that I flashed my stock firmware but now I get stuck on recovery screen. First it says "Erasing" and then the dead Android mascot shows up. Can't boot into system. Any suggestions? FRP Lock is still on and I can't flash TWRP, custom binary is locked by frp.
possible solution
Hi, how are you? I'm sorry for my english, I'm from Brazil and I'm using the ksks translator so with my j5 i used the frp hijacker (just put it on google) there you choose the phone model, put it in download mode, install the program on the computer, choose the model, check remove frp and a hijack it! and ready frp unlocked

tried it on another computer? Ive had that issue with my desktop/laptop(s). I never dug into what caused it to fail on the desktop vs working on a few laptops. Literally everything else works exactly as it should on the desktop so i just let it be an unresolved oddity. Likely not worth the time it would take to resolve. Anywho, try a different computer and/or diff cable. I just ordered an Anker cable from amazon and its thicker and more sturdy than the micro usb cable ive been hanging on to from my old blackberry tour. Cables are stupid cheap online these days, even for the very very good ones. Perhaps worth a shot, but i cant suggest that you spend money on anything. I can say that its what I would do.
