S8+ G955FXXU2CRED with Bootloader V2 - options for flashing, downgrade, FRP Unlock?

Short question: how can I downgrade or FRP unlock a S8+ G955F that is FRP locked and on very recent firmware?
Here are the details:
I am trying to assist a family member with a Galaxy S8+ (SM-G955F) that they have just purchased online. When purchasing it they were not told that FRP lock is on (FRP LOCK: ON) and OEM lock is on (OEM LOCK: ON). It was running Bootloader v2 on very recent stock firmware. It has been successfully flashed with BL_G955FXXU2CRED and AP_G955FXXU2CRED...
It was on G955FXXU2CRED firmware. I was able to successfully able to flash the Combination ROM COMBINATION_FA70_G955FXXU2ARE1 (full name COMBINATION_FA70_G955FXXU2ARE1_CL12792727_QB18097821_REV00_user_mid_noship.tar)
With combination rom, it seemed that I could enable USB Debugging, and also follow the steps for *#0808# IME to enable the appropriate mode for adb codes to be entered. I was able to find the device with 'adb devices', and I thought that the FRP unlock codes on the command line worked. But after re-flashing to the current Stock Firmware again, FRP lock was still there.
It seems I need to downgrade to Nougat 7.0, but I am on Bootloader V2. Odin identifies it by a FAIL with binary not matched (2 vs 1). So it seems that if I could get a method to keep Bootloader V2 and install Stock Firmware for Android 7.0 Nougat, I would be halfway there to fixing the FRP problem. However, I can't find any firmware or ROMs for G955F that includes Bootloader V2. This is identified by a U2 in the firmware name, like: G955FXXU2CRED . Is there a way to keep the BL Bootloader V2 but install AP ROM from Nougat?
I have spent many hours on this so far, and I just wanted to say thank you to all you guys who are helping on XDA, I really appreciate it. I have read about 7 day waiting periods for OEM UNLOCK but I don't see how it applies, as I can't do anything aside from use Combination ROM, use Odin, or go to the FRP locked FW which seems to be a dead end?
If there was a reliable method for rooting this G955F device with this G955FXXU2CRED firmware, I would be open to trying it.

Another note: AP SW Rev is identified as B:2 K:1 S:1

I don't think once a phone has the boot loader CRED, that the phone can be downgraded. Hope I am wrong.

I think you are right. The combination ROM seems to built on selinux version 7.
I think I need to root with twrp. But first I need to enable OEM unlock. I'm not sure if that will be possible with combination ROM or if I should flash latest stock and then wait 7 days??

same problem here... If an solution available pls write here

Flashing stock rom and waiting 7 days would be the safe option.
I am not exactly sure what you are trying to achieve.

I think I read someone on CarHDRom who flashed the rom via TWRP, and then when the phone booted into system for the first time at setting up, they changed the date to 8 days earlier, and when the phone setup was completed and booted into system, the OEM unlock was available.
Re: CRED I believe once it has been installed on a phone, you can not go back to a previous version (pre CRED).

It seems there are a few solutions to frp if you can selectively restore flash files. It looks like Samsung tool Pro can do this, but is there any free adb method?

Excellent.

I still can't get this to work. Have you purchased Samsung tool Pro to do the flashing of individual boot files? What version?

Hi there. I already bypassed the frp.. If you need. Hp with android 8.0 even with the binary 2. I have some comb files and working stock roms through odin. Feel free to pm me via my email [email protected]. Thanks!

Download latest odin and try again. I too got stuck in similar situation. Realised the issue is due to Odin. If you are using latest and encountered this error, try one version earlier.

I too can confirm that the combination-ROM works like a charm with odin. FRP kinda unlocked itself

SAMSUNG S8/S8+ SNAPDRAGON OREO ROOT discussion

I was curious about if there is ever going to be root for the s8 Snapdragon varient for Oreo.
I saw this thread
https://www.google.com/amp/s/forum....e-oreo-root-japanese-snapdragon-t3830039/amp/
If the Japanese Snapdragon bootloader can be exploited. Maybe in the future, the g950u/g955u can be rooted too?
If someone has information regarding this and knows developers who are working on this? I know that you can install safestrap on Oreo because of me1212(sorry if I spelled his name wrong) and partcyborg and other developers.
THIS THREAD IF FOR DISCUSSION AS IT SAYS IN THE TITLE. IT IS FOR DISCUSSING AND LETTING PEOPLE KNOW INFORMATION ABOUT THEIR SNAPDRAGON S8. Thanks for participating.

No. We use a exploitable nougat kernel. That samsung graciously left us open. The bootloader this day in age and is not exploitable to unlock. Specially on Oreo.
New exploits come along everyday so maybe one day. But not anytime soon. Me and several other look everyday for something possibly missed. But until some new major samsung bootloader exploit comes along which brings me to another point.
This day in age it's almost more worth it to only disclose any such exploits to samsung for nice payment.
The only known way as of now to unlock a U.S. bootloader in a engineering certificate which is branded by cpid to each device individually which means my cert will not work on your device. If not properly backed up mind you. Leaving you with a unusable device in several different ways. I know from first hand experience.

One last question.
I read that the Nougat firmware with Bootloader B1 can be rooted.
If I downgrade my G950u to Android 7, can I be able to root and flash Pie ROMs.?

You cant downgrade the bootloader. But there is this.
https://forum.xda-developers.com/galaxy-s8/development/root-t3904613
This allows safestrap on Oreo or pie. Which then you can flash the eng boot v5 which is a nougat bootloader but bit 5 then you can install su and a rev1 or 2 nougat system image. It sounds hard but really not bad. But the bootloader rev must remain that of 5

[Resolved] #Solved# Any Possible Solution to Downgrade Back to Nougat?

Hello all
Been a member here for some time now and have a perplexing issue.
I upgraded a Samsung Device SM T395 to OS Pie 9 and decided I didn't like it. (There are no other posts with help on this matter)
I kept the STOCK roms Nougat 7.1 and Oreo 8 and want to put Nougat 7.1 back on my device , but is proving difficult using ODIN 13.3.1 or any other version of Odin. The result is FAIL, that's using a combination of AP, CSC, CP and BL.
I managed to get Oreo 8 back on it, but want Nougat 7.1 original installed instead.
Can anyone tell me can ADB Fastboot be used to Flash a Stock Rom back on a Samsung Device or is Odin the only method?
I know there are other similar programs like QFIL and Qualcomm that I have used for the Mi Max brand devices.
The device was rooted with Nougat 7.1 originally and I have USB debug set and FRP / OEM lock off also. So there's no problem there.
The last resort (stupidly expensive idea :crying is for me to buy another exact device that has Nougat 7 installed when boxed up!
I don't see how upgrading to Pie 9 and then wanting to go back to the original factory installed rom is a big problem, can anyone explain?
Would a CUSTOM Nougat 7.1 rom work if installed via TWRP ?
I have also come across this COMBINATION Software https://samsungcombinationfile.com/samsung-sm-t395 that is supposed to allow the downgrading of Android software, but hasn't worked as I had been lead to believe.

Samsung firmwares can not be downgraded. This is due to your bootloader version number. The bootloader version is the 5th number from the right of the firmware being downloaded. You can also check in setting - about phone - software info - baseband version ( 5th number from right). You can also tell bootloader number in download (Odin) mode with a line saying AP SWREV B:? : K? : S?. The B is your bootloader number.
Combination firmware works on the same principle in regards to bootloader numbers.
You can only flash the same or higher bootloaders version numbers.
Custom roms will work as long as the bootloader version number is the same ( or higher ) than what is on you phone.

RE: spawnlives. Many thanks for clearing that up, I now understand. Like many other people I have been trying to mix and match BL files from different OS variants to try and trick the device into accepting the main Nougat AP file via Odin, but nothing works.
These NEW combination files suggest that it is possible to downgrade the BOOTLOADER files on certain devices. However I downloaded all that was available for my device and tried the lot and found the only ROM that would flash correctly and properly was the latest one with the Binary 4 Bootloader. The rest would not register in Odin due to MD5 binary error messages.
In download mode my device AP SWREV B:4 K:2 S:2. ( So I have binary 4 which was released in January 2019, I believe). and this must have been updated when I updated to OS 9 Pie , using all the AP, CSC , BL and CP files.
So as you say, the answer is either , look for a Nougat 7.1 rom with a BL file that has a BINARY 4 code. Or buy another device that has the original Nougat 7.1 installed, which is silly really. :laugh:

The best you can do is roll back to Oreo. A new phone running nougat would be the best choice. I don't use custom roms but they all seem to keep up to the latest version. I have not seen one that ( latest version ) that is nougat favoured.

RE:spawnlives
Yes having researched the total list of softwares for the SM-T395 device, it seems the BL was updated to 4 on the 2nd roll out of Oreo 8.1. And having checked ALL stock Nougat variants, there was never any release of 7.1 with a bootloader binary 4!
I presume the BL Binary version is the 5 character from the right on the picture. (underlined red) :good:
It would make sense for Samsung to give the end user a choice what software they want, by keeping the BL version the same or giving a choice of BL selections to allow upgrade or downgrade.
Anyway, I rolled back to Oreo 8.1 with the binary 4 BL. And unfortunately there aren't many CUSTOM roms , nor a working TWRP for the Samsung Galaxy Active Tab2.

Yes the bootloader is 5th from the right.
I don't own a tab2. If no work twrp can be found and you want to at least have root try using magisk and used the patch root method.
Also to avoid possible upgrade turn off automatic updates in setting - software update as well as in developer option - auto update system.

Have rooted the device no problem with magisk and patching the original boot img file. Then flashing patched boot img via odin. Causing device verification to need to reformat the device, resulting in correct root.
Once a device , this device is rooted, no official updates can be installed anyway. When you try to uodate software, a pop up shows as the device recognises the software has been modified.
As for TWRP there ISN'T any version of TWRP available for the Samsung Galaxy Active Tab2 (SM-T395). I have even emailed the makers , developers of TWRP why there isn't one in their device inventory list on their webpage.
So no TWRP, and NO custom roms either for this model.
My concern , was all about finding a valid , safe way to downgrade back to original Nougat 7.1. And until someone can produce a working image with a BL with binary 4. Then there's only one optiin and that is to buy another untampered device with Nougat 7.1 out of the box and leave it un updated. :good:

To answer your question of how is downgrading such a big problem, it is due to security reasons, to keep your device as secure as possible with the newest available software and the latest security updates.

S8+ (G955F) - RMM state -Prenormal

I want to flash TWRP onto my S8+ but im being blocked by the RMM. FRP and OEM is off but the RMM stays on prenormal. I have tried everything to my knowledge and what i have seen on XDA but no luck.
Is it even possible to bypass this?
My phone currently has the FEB 2020 security patch, is this a problem?
Please Help

Rmm/KG locks have been around since Oreo.
Generally to change KG and/or Rmm states takes 7 days ( 168hrs ) of ON Time with Internet Connection. Times may vary with devices.
While I have not tried them there are various threads on how to change the state.They may or may not work.
There are PC apps, like chimera, which also claim to be able to change the state.
I can't really recommend any one particular thread to try except for waiting for the time limit to expire. As I said some of the methods work for some but not others.
Flashing of stock firmware will reset these locks.
And only way to view these locks is in Download Mode.

The RMM state is now gone after the 168hrs as you said, which is awsome. I checked this morning. I unlocked the OEM and went to download mode, wasnt even showing. I'll try and flash TWRP later. I hope it doesnt gove me the "Official Binaries Only" error

Yes. Flashing stock firmware will relock OEM and KG and/or RMM state. Basically start the process again.
Note: Some phone can vary with times to be able to modify your phone. ie: my phone if I update firmware I can modify my phone as soon as I give it internet connection ( no sim ) using Wi-Fi.

Thanks for the clarification. I got locked after march security patch. I did all the stuff I found (date, reboots, etc) and nothing. I'll wait then.

Samsung A11 KG STATE: Prenormal OEM LOCK: ON, waited 168 hours no change. Can't unlock bootloader.

I have tried everything, I have flashed 4 different firmware versions in odin. Did all the updates, followed the guides and all that yet the OEM unlock option does not appear and kg status is still prenormal. You are probably wondering how I got here. I flashed a GSI rom that I did not like, I flashed back my firmware INCLUDING the bootloader. Flashing the bootloader reset it's state to locked. That in it self was no problem ill just wait 7 days and it will be unlockable again. But no KG state is still prenormal and oem is not unlockable. I just reflashed my firmware and I am going to start waiting *again* hoping that a miracle will happen. How hopeless is the situation with my phone, is it worth hoping it can fix this or will i have to just use the preloaded non rooted firmware? I had a hope to port lineage 18.1 to this phone but I am losing any hope of it happening.

No there is absolutely no solution, trust me. EDL method does not work anymore due to the security patch from last year having an new system. Unfortunately there is no working leaked firehose file since then. Don't even try any of the methods on youtube, rewritting the storage with the file from the factory was the only method.

thanks for your reply bro !!!!
I think 7 days up time and internet connect should fix the problem
i'm gonna try it.....
