I don't bother about CSC.

As long as it works in your region with your carrier and contains the language you want to use, is fine IMO.

Why do you want to flash another CSC?
[Samsung Galaxy S8 & S8+ Cross Device Development] Jeanbapti:
CSC

To bypass FRP. I don't want an other CSC but the same. I tried a UK one with Odin but my phone is now stuck on Samsung logo

It is Directive 1999/44 / EC of the European Union, which obliges any manufacturer selling its devices on the European territory, to offer a guarantee of two years on its products and all their components. The guarantee is material, whatever the software manipulations. So if the problem is material, the manufacturer or his distributor must replace the device or the defective part and that at his expense.

Just use your ext SD card, easier

In download mode, FRP LOCK off, OEM LOCK off , but when I flash twrp, it shows only official released binaries are allowed to be flashed.
[Samsung Galaxy S8 & S8+ Cross Device Development] It_ler:
Please re-read post #3 with the step-by-step installation instructions.

You have to flash the TWRP recovery tar file with Odin.

Samsung locked bootloader in Oreo. Read around everywhere ?

I don't like the sound of locked bootloader and Oreo. I don't think I'm going to upgrade. Nougat is juuuuust fine.

[Samsung Galaxy S8 & S8+ Cross Device Development] Tanak Vagu Avantang:
A quick question. Is PrinceComsy Odin still works with CRD7?
[Samsung Galaxy S8 & S8+ Cross Device Development] joso33:
I tried search but couldn't find a answer to my problem.

I installed latest TWRP on my S8 (Oreo). It installs fine after i format data and all that jazz.

Once the phone restarts I get into the first start up setup and reboot into TWRP (to flash custom rom) I lost the reformated data mount and have to redo it all.

Have i missed something?

I'm still running Nougat. Pros/Cons of upgrading to Oreo?
[Samsung Galaxy S8 & S8+ Cross Device Development] jeebspawnshop:
This is not the place for that discussion.

But long story short; no pros. It's all the same but with greater battery drain.

Better just to say "Off-topic" than to follow with something contentious that itself provokes further off-topic discussion.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
So I'm a little unsure if I can install twrp, I'm leaning towards yes, but just want to double check, had a hard time finding anything through search

But I see in the second post, in August that Merged AQG kernel updates from Samsung. NOTE: AQG or later bootloader is supported and REQUIRED from this version.

So that implies anything recently updated should work right? I'm just a little unsure since it's been so long since that post has been updated

I'm not sure which bootloader version I am on, but I'm on kernel version 4.4.111-13569719-QB18179712 and baseband version is G950FXXU2CRE3 (google has failed me in trying to find out how to find out which bootloader I am on)

Thanks
[Samsung Galaxy S8 & S8+ Cross Device Development] B3501:
Battery drain is subjective.
[Samsung Galaxy S8 & S8+ Cross Device Development] con_sau_may_tinh:
already turn on oem developer option

but when i flash recovery, it's ok but when reboot i got this message " recovery image signature check fail!!! reboot to avoid warranty bit set"

and my phone (G950N - version G950NKSU1AQF7) got boot loop!

only can go to download mode and up stock rom!

knox still 0x0

anyone have same problem?
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
I can't seem to successfully flash TWRP recovery on this baseband/bootloader combo personally...am stuck at the moment
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Someone in this thread says he has it working

https://xdaforums.com/galaxy-s8/how-to/discussion-oreo-final-t3746561/post76652101#post76652101

But I don't know if it was the first time installing twrp or he flashed the update and twrp and such still works, I asked, no answer yet. Im not sure if Im on CRED or not as I have a build number ends in 2CRED but then there is Baseband vesion which ends in 2CRE3
[Samsung Galaxy S8 & S8+ Cross Device Development] c3k:
Updated to CRED. No issues.
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
?

I think we mean it the other way round. After updating to stock CRED using Odin, you lose custom recovery, were you then able to flash/install TWRP recovery back using Odin?
[Samsung Galaxy S8 & S8+ Cross Device Development] c3k:
you can find my procedure here
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
Still not working on the stock ROM U2CRED with bootloader v2...tried a coupla times...sigh...
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Three questions

1. So you did install twrp on CRED and didn't update to CRED via a flash and TWRP still works, correct?

2. Which bootloader version do you have?

3. Do you need to flash No dm-verity? (could this be [MENTION=512828]Moe5508[/MENTION]'s problem?)
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
Exactly...

...for me as I understand it my bootloader got updated to version 2 and I'm pretty stuck at the moment and can't flash a custom recovery when I unintentionally ODIN flashed the U2CRED DBT firmware and my BL, CP etc got updated. There is no downgrading BL for me now once on the v2 bootloader...what I need is someone who can help either with a modified version of TWRP (ODIN flashable) or so I can flash it using stock recovery as an update.zip file...
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Im also on bootloader 2 and I hope sometime soon there is a way around it
[Samsung Galaxy S8 & S8+ Cross Device Development] manix7146:
Hello. I did not read before and I entered U2CRED. I have the same problem with the downgrade bootloader. There is no possibility to install TWRP. No OEM unlock option. Am I condemned to stock firmware ???
[Samsung Galaxy S8 & S8+ Cross Device Development] c3k:
1. Yes, updated with Odin as usual

2. CRE3

3. Never flashed, because SuperSU installer does this job

What happen when you flash TWRP?
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Your word update is throwing me off for some reason and maybe because I havent had a galaxy since the s5, you updated to CRE3 through Odin and not OTA? I got my phone and it was already updated OTA, I do know that I would need to install twrp through Odin, but there wouldn't be any updating through odin, does that make a difference?

Whats the number before CRE3? I though I read the number in front of that would be bootloader version, so mind is 2CRE3, or is that wrong?

3. I'll have to try it with magisk and see what it does, combine yours and someone elses steps to see when I need to flash it

Haven't flashed it yet, wanted to do my research first, don't want to risk bricking my new phone

[MENTION=512828]Moe5508[/MENTION] check out his answer to my 3rd question, that might help you out and why its not working for you
[Samsung Galaxy S8 & S8+ Cross Device Development] c3k:
I have 2CRE3 too.

I think you should flash without fear.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
So if I'm going to use your guide, I would flash dm-verity right before flashing magisk?
[Samsung Galaxy S8 & S8+ Cross Device Development] thewerthon:
Any news?

I'm on U2CRE3 and want to install twrp and flash custom firmware.

But I'm afraid to brick my phone.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Not yet, I haven't had much time to sit down and mess with it as I have a 14 month old running around, hoping to try later this week, also want to research how to fix if I get into a bootloop trying to install TWRP

[MENTION=512828]Moe5508[/MENTION] Any luck? Did you not flash dm-verity maybe when using [MENTION=2024094]c3k[/MENTION] 's guide?
[Samsung Galaxy S8 & S8+ Cross Device Development] c3k:
Not sure, but you should follow the guide, then yes.
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
Nope...I don't get the chance at all to flash (to boot into custom recovery) at all...

My fail happens repeatedly when I try to Odin flash the TWRP tar file in AP slot...

---------- Post added at 07:29 PM ---------- Previous post was at 07:26 PM ----------

That's where my fail happens always over and over again...the Odin flash of the TWRP custom recovery tar file in Odin 3.13.1 always fails...

I can boot into stock recovery and in there I have an option to flash zip ziles only as "APPLY UPDATE from SDCARD" or from ADB...
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Which version of Odin are you using? In one of the threads it mentions using Prince Comsy version of Odin

https://drive.google.com/file/d/1enVG5a_ocyjhRlta8AX_0b7LLoHWciVU/view
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
Am using the v3.13.1 as I read somewhere that this can now handle newer Oreo firmware...Let me try the Prince Comsy version...

EDIT: Nope no luck either with that Odin version...
[Samsung Galaxy S8 & S8+ Cross Device Development] thewerthon:
Just installed TWRP and everything was fine!
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
How exactly?

Coming from no custom recovery and having upgraded your device to U2CRED firmware using Odin? And then flashing TWRP after that? Is it just my device? Am really very very curious...
[Samsung Galaxy S8 & S8+ Cross Device Development] thewerthon:
I came from original recovery, oem locked system and upgraded to U2CRED via OTA (never used Odin before).

1. Enabled OEM unlock in developer settings

2. Started phone in download mode

3. Flashed TWRP through Odin (3.13.1) as instructed in OP

4. Flashed custom ROM, root and some mods.

That's what I did.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Are your drivers up to date? Using the usb cable that came with it? I've seen stuff like that mentioned in guides?

Also maybe redownload the files? Perhaps it was a bad download? I've had that happen with a custom rom on my old phone

Im hoping to try later this week, [MENTION=5180927]thewerthon[/MENTION] has me feeling optimistic about this working
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
My road is different: got to U2CRED firmware via an Odin flash. I had TWRP recovery and "accidentally/unintentionally" flashed the U2 bootloader using firmware from renovate-ice website...I then ran into the "only official binaries are allowed to be flashed" error message and then decided to odin flash/upgrade the whole thingy using U2CRED firmware (BL, AP, C and CSC)...

1) My OEM unlock is not enabled (am waiting out the 7 day period to access this in Developer Options menu...

The rest is pretty easy...I been flashing stuff/custom ROMs/recoveries etc now for a number of years...

---------- Post added at 12:14 AM ---------- Previous post was at 12:13 AM ----------

Yip, yip and yip...I have just about downloaded and tried all the latest U2 firmwares from across the globe///DBT, PERU, Trinidad and Tobago etc etc and tried them all...my fail still comes at the TWRP Odin flash in AP slot...
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Can you get your phone to boot if you try to reflash a stock rom only?
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
Oh my phone boots and works just fine so long as I flash a U2XXXX stock firmware with updated bootloader. Its booted up, set up and working just fine at the moment on a stock ROM...just no TWRP recovery. I always always want to run custom ROMs but now am stuck hence my desperation to fix this TWRP Odin flash issue so I can get back onto a custom ROM instead of stock...
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
Have you waited out the 7 days for oem to appear again? Also there are 2 work arounds for the rmm prenormal in download mode if you search XDA. If you need any help with this let me know :svetius:
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
Busy waiting out the 7 day period currently...3 more days to go.

Thanks. I'll PM you.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
For those who have done this and had it fail, did your phone go into a bootlop? If so how do I fix that if it was to happen? Do I just go to sammobile, find current firmware from there and flash through Odin? Could I use Smart switch instead to restore a backup?
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
Just flash the latest firmware from Samobile using Odin, as long as its got the same bootloader version (if on U2, then Bootloader v2)...

Smart Switch is lame...use Odin flash...

---------- Post added at 08:32 PM ---------- Previous post was at 08:29 PM ----------

There's a trick I've read in another thread for jigging the 7-day waiting period...but I'm only 8 hours away from waiting out the period normally that I don't wanna risk rebooting it and then having to wait another extra 7 days :D:(

But some users confirm its working on the U2CRED firmware...

1. Turn on plane mode

2. Go to time setting

3. Change automatic update to manual

4. Change date 8 days back

5. Restart phone

6. Turn on dev options

7. Restart phone

8.Change back date to normal

9. Turn off plane mode

10. You should now have OEM Unlock visible in Developer Options menu ( if not repeat operation till you have it)

Guys i cant install twrp i get only official crap can be installed. i am on the red software of oreo anyone know how i can install twrp
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
I think if you searched and read the past 10-20 posts or so, you'd find its been all about how to install TWRP on devices that are now running U2CRED firmware with updated bootloader...

Please search, read a bit...this question has been asked, and answered over and over again...
[Samsung Galaxy S8 & S8+ Cross Device Development] JCordero31:
ive read many post and found no one has a answer yet but sometimes developers or people read the last post and are quick to lend a helping hand because they find something somewhere else i might have not read. I appreciate your reply but please dont assume i didnt do research or didnt read. Ive been a member of this community for a very long time and was even a developer myself at one point. Instead of wasting your time telling me to read you could of just said nothing is available yet. You probably would have got a thanks for it.
[Samsung Galaxy S8 & S8+ Cross Device Development] Moe5508:
My apologies for my incorrect presumptions...I'm now rocking TWRP recovery again after the 7 day waiting period and happier for it...I just flashed it again successfully...what a relief...no more tinkering around updating BL for me anytime soon :o

You can PM me and will be happy to assist if you think I can.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Glad you got it figured out, I also just finished it and was about to reply that its working for me too!

---------- Post added at 10:51 AM ---------- Previous post was at 10:47 AM ----------

Did you unlock developer options, OEM unlock and allow android debugging?
[Samsung Galaxy S8 & S8+ Cross Device Development] JCordero31:
Oem is unlocked and usb debugging is on

I get only official binaries are allowed (recovery) device 2 binary 1 on prince cosmy and the patched odin 3.13.1
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
I used the most recent odin, didn't use prince cosmy
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
So just to confirm from what I've tried to do and what I could fine, at the moment, if on Oreo, I can't backup my rom with TWRP?
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
Yes you can. I made backup recently on CRED with twrp
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
You have the rmm prenormal. You need to wait 7 days without rebooting, toggling airplane mode or change SIM. By the way, use normal odin not prince comsy. Just to confirm.. does it say Rom prenormal in download mode?

If so follow instructions in the screenshot.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
How? When I try and I get data mount error even when I try to backup to my sd card, and when I try and select internal storage it shows as 0mb available (cant even flash anything stored on internal storage)
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
Try to manually mount /data. If it doesn't work it it's possible it wasn't installed correctly. When you flashed twrp did you do the format just after flashing twrp?

If I was you, I would start again and flash twrp again to make sure you can mount /data.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Do you mean step 3? If so than yes

Is this issue step 2? I just went with keep RO, is the only way to fix that is to reflash everything again from scratch?

How can I manually mount /data? I booted to recovery and found the mount option, I can check boxes in this menul, but I can't actually do anything

Part 2 - HOW-TO INITIALIZE TWRP: (for new phones)

1. If you completed Part 1 successfully, you should be in TWRP now. At this point, you will reach the screen asking you if you want to allow system modifications.

2. Select "Keep /system RO". (Don't swipe right or you may not be able to boot into system if you failed to complete next steps. However, you can swipe right to allow modifications if you are confident that you can complete next steps.)

3. Go to "Wipe" menu of TWRP and you will find "Format Data". Press "Format Data" and type "yes" to continue.

4. Go to "Reboot" menu and Press "Recovery" to reboot TWRP.

5. Download the latest dm-verity and force encryption disabler zip on your computer.

6. Transfer the zip to your phone.

- Option 1: MTP: Connect your phone with computer and just copy the zip to internal storage. (similar to how you transfer files when in system.)

- Option 2: ADB: Connect your phone with computer and run command "adb push /path/to/zip /sdcard/".

- Option 3: External SD: Copy the zip to an external SD and then insert the card to your phone.

7. Go to "Install" menu of TWRP and flash the zip.

Yes I did
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
You should, swipe to allow modifications, format, flash dm verity and that's it you should be able to mount /data.

Have you flashed magisk? This can also force mount of /data.

If you have already I would start again. Just flash twrp again
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
I have flashed magisk,found the data mount zip to flash, gonna try that

Really don't feel like wiping my phone again

Thanks

---------- Post added at 03:42 PM ---------- Previous post was at 03:23 PM ----------

So the data mount flash didn't work...sigh....guess I gotta install twrp again, do I just follow the instructions the same as before or do I have to do anything different since I already have twrp installed? I assume I'll have to wipe everything, correct?
[Samsung Galaxy S8 & S8+ Cross Device Development] callumbr1:
Yes, start again from scratch. It's a pain in the ass I know.

Use the previous version of twrp, I've seen a few times the latest version has issues mounting /data.

Follow the steps and yes you will have to format again. Without formatting data can't be mounted.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Now could that cause issues as im on 2CRED?

I know the one I used came out before my version came on, but seems like that could be an issue right? Guess if it doesnt work I can just try newest again

Plus I did originally keep it read only based on directions, though it could have been avoided as I've done this type of stuff before

And as long as I wipe as the directions say I should be good to go and only need to wipe in step 3 correct? Or do I need to wipe after step 7 too?

Part 2 - HOW-TO INITIALIZE TWRP: (for new phones)

1. If you completed Part 1 successfully, you should be in TWRP now. At this point, you will reach the screen asking you if you want to allow system modifications.

4. Go to "Reboot" menu and Press "Recovery" to reboot TWRP.

5. Download the latest dm-verity and force encryption disabler zip on your computer.

6. Transfer the zip to your phone.

- Option 1: MTP: Connect your phone with computer and just copy the zip to internal storage. (similar to how you transfer files when in system.)

- Option 2: ADB: Connect your phone with computer and run command "adb push /path/to/zip /sdcard/".

- Option 3: External SD: Copy the zip to an external SD and then insert the card to your phone.

7. Go to "Install" menu of TWRP and flash the zip.
