[Samsung Galaxy S8+ Guides, News, & Discussion] Geekser:
I flashes this OREO per the OP's instructions (Thanks to the OP) one week ago - and immediately after flashing attempted to flash TWRP. It failed, I got the dreaded 'Official Binaries Only" error message, I was locked out and had to wait 7 days. I did a lot of research and found that others had discovered this RMM State thing that has been talked about so I checked in download mode and sure enough, I was "Pre-NORMAL". So I waited. 7 days. 168 hours. Last night, at exactly 802pm, I checked Developer settings to see if my OEM unlock had re-appeared and it was not there. I freaked - it was 7 days - so before going off the deep end, I rebooted and checked again - still no OEM. So this time I turned off the phone completely. Then powered it back on - and this time when I checked Developoer Settings, OEM Unlock was sitting there - happily unlocked and waiting for me to flash twrp and the RMM state Fix.

I have since flashed TWRP, the RMM state fix and the custom ROM - Minotaurus V20 (you can find it on Telegram) and I am happier than a pig in mud. I can't help but wonder why Samsung is making things so difficult - i mean come on - they lock the bootloader but then allow it to be unlocked after 7 days? Why? How does that offer any additional secutiry ?(Assuming their reasons are rooted in secutiry issues)

In any event, for anyone else waiting the 7 days. Be sure to turn off the power on your phone at the 7 day mark. then reboot and go into developer settings - you should see OEM unlock just like I did.

Hi guys,

I flashed it on my phone but somehow I only had 16GB internal memory. Can anyone help me?
[Samsung Galaxy S8+ Guides, News, & Discussion] dansimko:
It was already solved in this thread. You need to do a factory reset or if that does not help, try repartitioning the device by re-flashing the firmware with CSC_* (not HOME_CSC).
[Samsung Galaxy S8+ Guides, News, & Discussion] skyfrost:
thanks bro, i will try.
[Samsung Galaxy S8+ Guides, News, & Discussion] jack allen:

Here are the latest CRB7 odin flashable files for G955F (repacked using this guide). I can confirm it is working perfectly on my S8+. Feel free to add this to OP.

[Samsung Galaxy S8+ Guides, News, & Discussion] Leon:
I used this method to update CLICK. Can I just flash it over?
[Samsung Galaxy S8+ Guides, News, & Discussion] cretu01:
Yes.
[Samsung Galaxy S8+ Guides, News, & Discussion] dazed1:
I have downloaded and extracted your files, however none of them is called as the odin files - CSC, BL, AP and so on.
[Samsung Galaxy S8+ Guides, News, & Discussion] cretu01:
You don't have to extract them. They are already in the BL+AP+CP+CSC/HOME_CSC format.
[Samsung Galaxy S8+ Guides, News, & Discussion] dazed1:
Google zipped the files, when i download them, what should i do, i unpack the main file, and add - match the unpacked rars at Odin>?
[Samsung Galaxy S8+ Guides, News, & Discussion] Leon:
One more question, this is stock firmware and wont trip knox right ? :D:confused:
[Samsung Galaxy S8+ Guides, News, & Discussion] XkobiX:
Did you just put those files in the moded ODIN?

[Samsung Galaxy S8+ Guides, News, & Discussion] Leon:
This is what I did but in the settings still says crap.I will try again.
[Samsung Galaxy S8+ Guides, News, & Discussion] dazed1:
Check the size of the files,

[IMG="https://i.imgur.com/XERfTEa.png"]https://i.imgur.com/XERfTEa.png[/IMG]

Are the files you have flashed same size?

Edit, look at the bottom, at the top it will state CRAP, but on the bottom should be CRB7.
[Samsung Galaxy S8+ Guides, News, & Discussion] Brotuck:
Normally you download a zip file, but when you unpack the zip on the PC/laptop then the files are this size
[Samsung Galaxy S8+ Guides, News, & Discussion] panchuckles:
I´ve created DBT CRB7 firmware with this method (only S8+ sm-g955f exynos):

1) Download the file "SM-G955F_OREO8.0_CRB7.rar" https://www.androidfilehost.com/?fid=890129502657584963

2) Extract it and you will see 5 files (AP,BL,CP,CSC and HOME_CSC)

3) Connect your pone in download mode using ONLY Prince Comsy's modified Odin (this is mandatory), and flash :D

Ps. If you dont want to loose your data, use HOME_CSC instead CSC.

and of course, I've tested it before upload
[Samsung Galaxy S8+ Guides, News, & Discussion] T0nyCr:
new galaxy s8 oreo update now rolling out in more regions
[Samsung Galaxy S8+ Guides, News, & Discussion] 8139david:
Can you put a pic showing what to select on Prince Comsy's modified Odin in order to use HOME_CSC instead of CSC? (I'm lost.)
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
What part are you having difficulty with?

If you want the phone to be wiped, add the CSC_OXM file in the CSC tab, if you don't want to lose your data, use HOME_CSC.

Thank you [MENTION=5941094]cretu01[/MENTION] [MENTION=3365793]Brotuck[/MENTION] for the CRB7 mirrors, I'll update the main post tomorrow.

Multi csc? TPH is included? Old or new Odin?

Thanks for sharing!

[Samsung Galaxy S8+ Guides, News, & Discussion] XkobiX:
This is multi csc and TPH is included in the OXM group which is the multi csc... You need to use a moded ODIN (new one) by prince...
[Samsung Galaxy S8+ Guides, News, & Discussion] KevinBaker:
Hi, hoping I can get some help... I've downloaded the firmware from the links above, loaded into the Prince ODIN, and when I hit start the phone resets straight away... ODIN still says pass. Any ideas please? I've previously updated using ODIN to unbranded XSA firmware using the same setup.
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
Are you using CSC or HOME_CSC?
[Samsung Galaxy S8+ Guides, News, & Discussion] KevinBaker:
HOME_CSC... was trying to avoid re-setting up the phone.
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
Odin only goes to PASS immediately if you use HOME_CSC when you're already on the CRAP firmware.

Are you on CRAP or an earlier firmware?
[Samsung Galaxy S8+ Guides, News, & Discussion] KevinBaker:
I'm on the latest XSA firmware which is AQJ5
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
What files are you flashing in Odin when you click start?
[Samsung Galaxy S8+ Guides, News, & Discussion] KevinBaker:
All of the appropriate ones - AP, BP, CP, HOME-CSC etc. Tried with official Odin and Prince version - setup has not changed from when it was recently used to flash to XSA firmware from HK firmware (although I used the full CSC then, not Home)

Edit: looks like I've got it sorted. I was using the files from kernel.killer but they wouldn't work - now used hussein1 files and it's worked fine. CSC is showing as DBT/DBT/BRI - I'm in XSA region - there is no XSA release yet, should I just leave it as is?
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
I just realized, XSA isn't part of the OXM multi-CSC so you can't use HOME_CSC until you're part of OXM, which isn't possible since there is no Australian CSC present in the OXM CSC.

You'll have to wait till Oreo is released for XSA to flash it OR, flash CRB7 (replacement for CRAP) and lose your XSA CSC and probably get a German or British CSC instead.
[Samsung Galaxy S8+ Guides, News, & Discussion] KevinBaker:
Looks like that's what I have done... I was using the files from kernel.killer but they wouldn't work - now used hussein1 files and it's worked fine. CSC is showing as DBT/DBT/BRI now - used the HOME_CSC and have not lost any data.

[Samsung Galaxy S8+ Guides, News, & Discussion] carcassudo:
Hey guys

Recently i flashed CRAP and still doesn't have OEM under developer settings.

May i flash CRB7 using Prince Comsy Odin?

Tks
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
Yes you can flash CRB7.
[Samsung Galaxy S8+ Guides, News, & Discussion] DJBhardwaj:
I am in a confusion here. Anyone?

Are the files provided in the OP modified .tar or lz4? The instructions in the OP are for those who want to modify their device-specific files on their own?
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
If you want to download using SamFirm, you have to follow the steps in the OP.

The 3 mirror links given in the main post have been uploaded by users who have already followed the steps and made the files Odin-ready.

So the files in the mirror links are not .lz4, but just standard files which can be flashed through Odin with no modifications required.
[Samsung Galaxy S8+ Guides, News, & Discussion] DJBhardwaj:
Thank you so much for the clarification. Indeed, the steps are simple enough for anyone to follow. So thanks for that as well. :good:
[Samsung Galaxy S8+ Guides, News, & Discussion] RodolfoKSP:
Thank you!
[Samsung Galaxy S8+ Guides, News, & Discussion] :
All good here, used the files from the Google Drive and with the modified Odin, piece of cake.

Thanks all!
[Samsung Galaxy S8+ Guides, News, & Discussion] William Haven:
So can I install CRB7 directly on top of AQK7 (Nougat Nov Patch)? Or do I need to first update to ZRA5?
[Samsung Galaxy S8+ Guides, News, & Discussion] giacomomancuso:
So the 3 files 9n the First page are Odin (not modified) ready? Or I have to use the modified Odin? And can I upgrade to Android 8 directly from Android 7 or I have to upgrade to CRAP version before? thank You.
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
Just know that whenever you're flashing an Odin ROM, you don't need to be on a specific android version or build to flash it.

You could be on any Nougat build and flash up directly to CRB7.

The 3 mirror links are Odin ready. They require no modification and can be flashed through Odin normally.

You can be on any build or Android 7.0 and flash directly to CRB7.
[Samsung Galaxy S8+ Guides, News, & Discussion] henklbr:
Odin, or the MODIFIED Prince Comsy's Odin?
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
Either one works.
[Samsung Galaxy S8+ Guides, News, & Discussion] henklbr:
Are you sure, CRB7 can be flashed with i.e. the OFFICIAL Odin v3.12.3 or v3.12.7?

Why is in OP stated, that you'll have to use Prince Comsy's Odin?
[Samsung Galaxy S8+ Guides, News, & Discussion] William Haven:
Just updated to CRB7, super fast and easy. Only one question, both the baseband and firmware are supposed to still be CRAP?

https://s.amsu.ng/3vw19WnFzDYN
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
Initially when this guide was created, me and the guys who made it thought that the modified files uncompressed from their original .lz4 extensions wouldn't get flashed with normal Odin.

However, we later discovered that it flashes just fine.

So you can flash CRB7 (provided that it's uncompressed) through any Odin version including and newer than 3.12.3. Prince Comsy's build isn't required as proven by many users in this thread. :)
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
Yes. Changes were only made to Android system, hence only the build number changed to CRB7.

CSC and baseband remain CRAP as no changes were made.
[Samsung Galaxy S8+ Guides, News, & Discussion] tonster76:
Secure check failed

The modified (non-MD5) files fail for me with SECURE CHECK FAILED.

And the MD5 one's don't work because ODIN can't decrypt the lz4 files?

I'm stuck with a brick at the moment due to my confusion, does anyone know a way out?
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
Download the files from the OP, flash in Odin 3.12.10 and it should work just fine.

And yes, right now, Odin can't wrap it's head around .lz4 so it gets stuck at 'SET PARTITION' when you try flashing.
[Samsung Galaxy S8+ Guides, News, & Discussion] tonster76:
Geez thanks Murtuza, I thought I had done that, but I went back to do it again... and realised I have an S8!!! not an S8+.... oh man... now following your other steps with 7zip Standard from the SM-G950F stock ROM
[Samsung Galaxy S8+ Guides, News, & Discussion] giacomomancuso:
So whatever I download (of the 3 links on First page) is Odin ready? Right?
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
Yes it is.

for field CSC i choose file HOME_CSC_OXM ?
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
SamFirm gets you the full ROM file directly from Samsung servers.

Yes you can use new Odin and HOME_CSC to keep your data intact.

It's for installing the full ROM, but you can get just the BL and modem if you download the full ROM and flash only BL and CP using the new updated 3.13.1 Odin.
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
Read the red highlighted text in the main post.

New Odin is now available. You don't need to decompress the files now and they can be flashed using Odin v3.13.1 without any modification.

Samsung pay will stop working if you flash this rom. Mine stopped working (UK). Although Android pay still works fine.
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
No it won't.

Samsung Pay works just fine if you remain on the same CSC.
[Samsung Galaxy S8+ Guides, News, & Discussion] houstie:
I didn't know that. So if I flash csc_home from my UK Nougat ROM, this will work? Didn't know you could mix ROMs & CSCs.
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
HOME_CSC doesn't mean you keep your original CSC, that happens anyway, it only ensures that the internal storage is not wiped.

CSC_OXM also doesn't change your CSC, it just ensures that the internal storage is wiped.

If you are already on an OXM ROM and your CSC is part of the OXM multi-CSC, flashing any newer OXM ROM over that with either HOME_CSC or CSC_OXM will not change CSC, it will remain on the one you're already running.

For example:

In Pakistan, the latest ROM is still AQK7 (November Nougat), however PAK is part of the OXM Multi-CSC, so I downloaded AQL5 (also OXM ROM) for Germany, but when I flashed it over my PAK AQK7 with CSC_OXM (wiped the phone), my CSC still remained as PAK.

[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
What I wanted to say was, the whole decompression and all the steps listed in the OP can be avoided if you just grab the ROM and flash using the new 3.13.1 Odin.

Question: I have Smart SMA-CSC(Philippines) telco-locked/openlin sim and still no Oreo update.

If I flash CRB7-Oreo Taiwan, India or Germany what do I get from those CSC? Like Apps, Samsung Members benefits? Or nothing will change?
[Samsung Galaxy S8+ Guides, News, & Discussion] MeltdownSpectre:
You'll probably get DBT (German) CSC.

Future software updates will be pushed based on when they are released for DBT, not SMA.

Features like VoLTE, Samsung Pay and WiFi calling will not work.

Your internal storage will be wiped.

Lastly, I wouldn't recommend this on a locked phone.
[Samsung Galaxy S8+ Guides, News, & Discussion] cheschanco:
That's what I'm worried about if my sim(Smart) will work or not work if I will flash other region like Taiwan. I need to use Smart on Sim 1 to able use other Sim slot (Openline) by the way I'm using 2 sim for business purposes.
[Samsung Galaxy S8+ Guides, News, & Discussion] red_brindle:
Your bootloader is locked, you cannot flash any ROM unless it comes from your Telco.
