[Samsung Galaxy S8 & S8+ Cross Device Development] Alcibiade:
Or you can buy a Snapdragon in countries where the Bootloader is not locked (Hong Kong, China, etc...). This is more carrier driven than hardware driven.

The only question is whether (and when) there will be support for TWRP on Snapdragon with unlocked bootloader...
[Samsung Galaxy S8 & S8+ Cross Device Development] goRt:
I was using this version when experiencing my last round of restore issues.

When I've got time I'll try again and save the logs.

Sorry, have you tested using 100% stock ROMs as I report, or your own modified ROM as you state?

took backup to sd card ( samsung 64gb evo+ class10 )

and it boots fine:D

Hi. Not sure if I'm doing something wrong but the dm verity zip on the 1st page won't download and the all in one zip that includes twrp and both flashable zips on page 5 (android file host) says error 404 not found. Where can I get the dm verity zip and or the magisk zip?

Thanks

Right now I using stock Samsung firmware AQDG with TWRP+Magisk+no-verity-opt-encrypt, But I want to update to latest fw AQEB (also stock).

But I have question.

What steps I should repeat after flashing new firmware via Odin ?

I want use HOME_CSC , and keep all setting and data.

I faced the same issue with Error 255 while restored my Nandroid Backup with previous TWRP version on my G955FD. This issued wasted a lot of time for me to reflash stock FW. Not sure it will happen with latest version, I haven't got test it...

P/S: I had tested to make a Nandroid backup with latest version of TWRP, and the ERROR 255 came again....

I used this to flash my S8+ with the csc switching tool which worked perfectly. Now on multi csc in the UK.

Stupid question I know but there is no way to reset Knox to 0x0? I can't use quite a few apps now due to knox being tripped and I want to stay on stock rom.
[Samsung Galaxy S8 & S8+ Cross Device Development] force70:
no you cannot reset knox and that has been the same since it was introduced and well known at this point as its beem years

You guys really need to learn to use the search function for the easy stuff.

Like I said. I know that it's probably not possible. There used to be a way to do it in 2016 which is no longer valid. It's just a question. No need for you to get on your high horse!

Luckily Samsung is going to reset the counter for me tomorrow :)

Samsung won't and can't reset knox counter as it's an actual efuse on the motherboard of the phone. Once tripped it fuses and burns out. It's a security feature that is impossible to reverse.

I've scanned the thread and can't find a definitive answer so I'd rather ask and be called out for it, than risk flashing this and bricking my device (this will be my first Samsung, all my previous devices have had an official bootloader unlock method via the manufacturer).

I'm guessing this works for ALL Exynos S8+'s, whether they're network branded or not? I get my EE UK handset tomorrow and plan on rooting etc over the weekend so just want to make sure.

Has anyone done this on an EE Branded handset?

Hi, i have a problem, i am on official firmware and recovery, my phone is encrypted, once i flash TWRP using ODIN the phone reboots and i have an error message about verification failure and asking to reset the phone, i tried flashing no-verity-opt-encrypt-5.1 using an sdcard but i still have the same error message and i have none of my partitions mounted in TWRP

Do that and your problem will go away.

Help!!!!! I have the G950F and I installed twrp after going into developer options and activating OEM. I also turned USB debugging on. TWRP was installed correctly, but the problem is when I go to format data it does not. It will install the anti root removal kit and magisk but no root. What am I doing wrong?
[Samsung Galaxy S8 & S8+ Cross Device Development] marcel112:
when i flash magisk v12 in twrp i get error.

I cant seem to find v12_arm64 version to flash

Ok, i can just retry post 3 , step 2 now. Or do i need to start all over?

O, and after failed magisk flash i activated pin on reboot. Do i need to disable again? I activated , i have red i need it to flash stock using odin.
[Samsung Galaxy S8 & S8+ Cross Device Development] marcel112:
I found the problem:

because i have used cf-auto root before my boot image is allready altered..

after returned to stock everything is good now.

From stock i could get all the steps completed and magisk is working

I flashed magisk without errors, magisk manager is on phone, but still dont have root

i check with root checker and TB doenst have root.

What am i missing here?

I flashed Batman rom magisk included, that one works

[Samsung Galaxy S8 & S8+ Cross Device Development] Chinhai:
Now boot into twrp and do the following:

- Delete TWRP folder located in /storage/emulated/0 (Move out your backups if you have)

- On twrp press Reboot and recovery

- You'll see a screen and don't swipe. Press on Keep read only

- And then you can format data by going to Wipe>Format data and type yes (Swipe right) NOTE: make SURE this will delete all of your files

-Now you can flash dm-verity and force encryption disabler zip

Reboot will take awhile as your data is wiped

Hope this works. Cheers!

CPU Spy is tell me the phone never goes to deep sleep, and I've notice much higher battery drain.

Is there a fix, work around for this?

Edit: I was never able to get Deep Sleep working, so I flashed stock back CP, AP, BL, CSC. Then rooted again exactly the same as before, and Deep Sleep started working.

Hi guys, with the lastest TWRP, I can't convert /data or /cache into F2FS, is it normal ?

(After Convert cache and data in F2FS, TWRP say that it is in F2FS but when i boot in my rom, it is in ext4, and after rebooting in TWRP, it is not in F2FS, it's like F2FS didn't stuck)

Hey guys, apologies if this a noob question but i'm kinda stuck.

[Samsung Galaxy S8 & S8+ Cross Device Development] cantenna:
So is anyone here using adoptable storage? Any issues as of lately? I'm running into a stability issue and I think that it may be related to mixing adoptable storage with the latest version of twrp (didn't have this issue with previous versions of twrp.)

On two occasions now all has been working fine, but upon booting into twrp and exiting, upon reboot, a number of app fc related crashes occur i.e. process.media, phone, samsung account...

For now, I'm going to stop using adoptable storage (will be the first time without it for almost 2 years)

Thing is, enabling adoptable storage enforces another kind of encryption (i think, different from the encryption we initially disable to install twrp, but I could be wrong) point is, I guess because of adoptable storage encryption it is not supported by twrp, perhaps the cause for the issue. Or perhaps adoptable storage is supported by this version of twrp?
[Samsung Galaxy S8 & S8+ Cross Device Development] goRt:
Still unable to restore

I am still unable to restore data.

I have done a complete reflash of the phone.

I have wiped data, installed DM-verify / encryption disabler, rebooted

I then attempt to restore data and it fails part way through, it fails at exactly the same point until I wipe data again and then it fails at a different point (but this point is then repeatable until wipe, then a new failure point is chosen!)

If I then format /data as EXT3 (or F2FS) then the restore is performed first time without issue, however, I'm then unable to install ply store updates or apks.

Others have reported this issue in this thread but we continue to be ignored (or worse derided).

I attached the recovery and kernel log as previously promised.

I'm off to reflash my phone, get TWRP up and running and then perform a titanium restore (again!)

What further PD do you required?

Just a quick question. Will it ever be able to go back to stock in the future and get knox back like stock? Maybe not now but in the future. Or is it impossible?

help to flash twrp-3.1.0-r1_dreamlteks Ths

I'm sorry, but I'm not ashamed to ask for help in the case of the flash of the new TWRP twrp-3.1.0-r1_dreamlteks, normally in the Samsungs it was put in the section of: ODIN AP, and that's it, but in the case of S8 MS-G950F which is mine, I do not even get it to boot into the new Recovery.

Sometimes it gives me a message that I have to make a wipe and leave it from the factory and others, after passing the wipe in its stock recovery it gives me the final error and the message of .... blocked by FRP lock in red.

It would be very grateful if we were indicated with more or less detail the steps to follow to get the TWRP to work for us so much, I at least, we have waited.

Thank you very much to all.

This is for Exynos variants

Snapdragon = no

Exynos = yes

By the way, this was discussed for weeks before release. The only question was if Samsung would still allow Exynos to be unlocked. We knew Snapdragon was always going to be no.

Reason why OEM unlock isnt an option on my AT&T s8?
[Samsung Galaxy S8 & S8+ Cross Device Development] Terry.666:
HELP Please!

Hi

Unfortunately I tried the method from here: http://www droidviews.com/install-twrp-and-root-samsung-galaxy-s8-and-s8-exynos-variants/ but all gone wrong!...

First the TWRP for the 8+ didn't work as going to recovery the screen is dead (no touch...)

As I couldn't restart the phone I tried the S8 link and this time the phone responded to touch in the TWRP...

Happy that I just had a wrong link I tried the rest of the instructions flashing the Magisx (in my excitement, without making a Backup...), couple of "red" messages during the root flashing fast enough to make it difficult to read and then automatically reboot to a Samsung message Saying that it need to reset the device as the security check failed and only choice the reset... Unfortunately after click in "Reset" button it din't succeeded as had many "red" massages when it tied to reset...

Then I tried to flash the "no-verity-opt-encrypt.zip" hoping that it will allow at least the Samsung to reset the phone...

Wishful thinking...

After more "red" messages during the flashing back yo the same Samsung message...

Despaired then I tried to flash again the TWRP and during one of the many tried we had a electricity "spike" in the middle of flashing it and after that I have a phone which I can only go to "download" or the dead/no touch "recovery" and the Odin can't "see" the device even after I installed "new" windows drivers even the KIES/SMART SWITCH from Samsung...

Do you know any way to make the phone readable by the PC again? I may find a Samsung ROM to flash it then...
[Samsung Galaxy S8 & S8+ Cross Device Development] OrphanBlack:
Try this... has worked for me.

Download the latest Odin 3.12.3 http://www.teamandroid.com/2016/10/09/download-odin/

Done

Good Luck

Your answer is just above your question and you didn't even bother reading it, did you? :rolleyes: Seriously, THIS was the post just above your question. And the thread is CLEARLY MARKED in the title Exynos.

Samsung locked the bootloader on the Snapdragon variants. Only Exynos variants can be unlocked.

But you can use Exynos in the U.S. There's no reason to buy the U.S. carrier versions. Well, unless you are Verizon or Sprint, which are the CDMA-handicapped U.S. carriers. Exynos has no CDMA because it's a dead technology.

LTE Bands: FDD: B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B12(700), B13(700), B17(700), B18(800), B19(800), B20(800), B25(1900), B26(800), B28(700), B32(1500), B66(AWS- 3) | TDD: B38(2600), B39(1900), B40(2300), B41(2500)

[Samsung Galaxy S8 & S8+ Cross Device Development] ChazzMatt:
yeah, sorry, I was copying and pasting from the s8+ op.

Still it's for Exynos variants .
[Samsung Galaxy S8 & S8+ Cross Device Development] nk33:
ok - sweet.

I just wanted to confirm the method here:

1) flash twrp - then reboot straight to twrp

2) Install the zip to allow disabling encryption

2) wipe data

3) disable encryption (is this option in TWRP? if so which section)

4) Download mode

5) reflash twrp with odin

6) go straight to recovery

7) flash the root zip

is this right? do you need to go to twrp twice or is once enough
[Samsung Galaxy S8 & S8+ Cross Device Development] pax2011:

Nope.

Once you flash TWRP, and then if you feel like going back to stock, you just flash the stock ROM, the phone will have all its original files including stock recovery but KNOX will always remain 0x1 and you can't revert it back.
