I like to be first.

Encrypting the data partition is very important - for example if you travel into the US and don't want the

border police to examine your phone and copy your data.

I use encryption since years, beginning with a S4 mini and CyanogenMod.

Therefor I posted this bug - any advice, how to speed up the fixing of the bug?

Hey guys,

So I installed TWRP successfully and rooted - all fine, but after setting up my apps the phone started to just shut down out of the blue and the only way to start it is in download mode.

I did factory reset, the problem continues.

I only rooted to recover some deleted files and I really want to get back to factory now, as currently the phone is completely unusable with twrp.

Any help is appreciated.
[Samsung Galaxy S9 & S9+ Cross Device Development] Lewdog45:
Did you install root or SuperSU before you installed the ROM?
[Samsung Galaxy S9 & S9+ Cross Device Development] nickems:
I installed SuperSU, haven't installed any ROM.
[Samsung Galaxy S9 & S9+ Cross Device Development] Serpentinefire76:
Have you tried shutting down your device, then pressing up volume + power + bixby button simultaneously to get into TWRP?

Are you positive you've downloaded and flashed the correct TWRP version specific to your device?
[Samsung Galaxy S9 & S9+ Cross Device Development] BokkieAndijk:
I can't download from there because every time when I try to download it asks me to login again and when I do that again I don't be redirected to the download page. When I go there, it asks me to login again. So now my phone and the Sammobile page are both in a loop. Hehe. :))

That used to happen to me too - what you need to do is logout when it asks you to - then when you log back in - go thru the steps to change your password.

Check special note 1 and 5.

Note that Samsung may suck you by hiding "OEM Unlock" option, according to this thread https://xdaforums.com/galaxy-s9-plus/how-to/guide-root-s9-oem-fix-t3763974 . However, I don't have this kind of problem so I can't give advice if this is the case.

FYI: You can download Odin 3.13.1 at #3.
[Samsung Galaxy S9 & S9+ Cross Device Development] sireniankyle:
I wasn't using the right version of Odin. Even though I found this out before I saw your post, I still threw you a thanks for getting back to me. I feel really stupid for making such a simple mistake.

What phone model do you have, I really hope you don't have any US model phone, snapdragon...

edit: on the OP

Exynos variants such as G965F/FD/F-DS/N ONLY.

In NO way it is compatible with Snapdragon variants including but not limited to American(U/U1/A/T/P/V), Chinese(0/8/6), Hong Kong(0), Japanese(SC-*), Canadian(W) variants.
[Samsung Galaxy S9 & S9+ Cross Device Development] FRoZeN ACiD:
Its not a snapdragon. Just downloaded the original firmware and finally got my phone back to boot.
[Samsung Galaxy S9 & S9+ Cross Device Development] nickems:
I installed the TWRP from this thread.

The recovery seems to be working fine, I can enter it, all functions work and I can flash with it.

I flashed NEMESISKERNEL and SuperSU, which seems to have fixed the problem with the phone turning off.

The new problem is the phone is noticeably slower and Wi-Fi stays scanning, but cannot find any networks to connect to.

At this point, I really want to get back to all stock and be done with this madness, but the Sammobile site isn't working properly as well, so I can't download the OEM ROM. If I flash the OEM, will this rid me of the TWRP and whatever else custom I already have?

[Samsung Galaxy S9 & S9+ Cross Device Development] gusnz:
Thanks for all your work on TWRP! I have the same problem as other users with TWRP being unable to recognise LineageOS's encryption. I installed using the instructions from the Lineage star2lte install wiki and did an "Advanced Wipe" of the system, cache and data partitions (it wiped the internal storage completely; I didn't select "Format Data"). Lineage installed, started and I enabled encryption with a password within LOS, and it works well. TWRP 3.2.1-2 recognises /data is encrypted but won't accept the password to mount the data partition.

Hi,

I tried to Flash the TWRP via Odin coz i got the OEM Unlock and had my phone reset and everything. but when i try to flash TWRP, it fails and the phone says that "Only official released binaries are allowed to be flashed"

RMM STATE : Prenormal

FRP LOCK: OFF

OEM Lock: OFF

Does that mean i have to wait for sometime or am i doing something wrong?

Thanks
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
When you reset it, you triggered prenormal, which means another 7 days.

If you had read more, you would have seen that when you selected reset, you should have immediately went into download mode before it reset, and you could have ODIN'd TWRP at that time.

I have heard there may be a way to speed up getting rid of prenormal, but you will have to search hard to find it.

As soon as prenormal is gone, flash TWRP and then one of the ROMs that permanently freeze the OEM unlocks.
[Samsung Galaxy S9 & S9+ Cross Device Development] Rachirod12:
Thanks for that.

So it means I should of went in to Download Mode as soon as I enabled OEM Lock in Developer options, to flash TWRP?
[Samsung Galaxy S9 & S9+ Cross Device Development] ianmacd:
In theory, yes.

You can try this trick. It has bypassed the 7 day wait for OEM Unlock to appear, but it's not clear if it also works for RMM Prenormal. Try it, as you have nothing to lose now.
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
Yes, but that's history. Keep watching for prenormal to disappear, and when it does - install TWRP and go from there.
[Samsung Galaxy S9 & S9+ Cross Device Development] Rachirod12:
Thanks for all the info guys

Changing the time trick didnt work for me, I did try it couple of times.

Dear all friends, I am still waiting for OEM unlock to appear. I have some question. After enabling OEM unlock, it will prompt to factory reset. But if I choose no, I think it will revert back to disabled state, yeah? So my question is, how to reboot to download mode after enabling OEM unlock without doing the factory reset? Thanks in advance.
[Samsung Galaxy S9 & S9+ Cross Device Development] bobandar:
Same question here, will get the oem mostly today.
[Samsung Galaxy S9 & S9+ Cross Device Development] ianmacd:
Choose to factory reset, but then quickly intercept the reboot with the hardware keys and reboot to recovery. If you reboot to system, the factory reset will take place, but if you catch the reboot and go to recovery instead, you can prevent the reset.
[Samsung Galaxy S9 & S9+ Cross Device Development] zidane02:
I see, then after it booted to recovery, should I turn off the phone via recovery and boot to download mode? or boot to system 1st via recovery then turn off the phone then boot to download mode?
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
If they don't have recovery yet, they should go straight to download mode with the keys and then ODIN Recovery.
[Samsung Galaxy S9 & S9+ Cross Device Development] rsktkr1:
Reboot into download mode recovery not installed yet.
[Samsung Galaxy S9 & S9+ Cross Device Development] edzamber:
Hi guys

Sorry for asking again but does someone know why use theses commands in zips updater-script cause freeze in TWRP 3.2.1-2 ?

run_program("/sbin/reboot");

Or

run_program("/sbin/reboot", "fota_bl");
[Samsung Galaxy S9 & S9+ Cross Device Development] zidane02:
This is very clear, thank you.. So after I intercept the reboot using hardware keys to boot into download mode, I can go ahead and flash straight TWRP? TIA.
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
Yes. I did not know that and had to wait another 7 days. Do not touch unlock anymore- the should be unlocked.
[Samsung Galaxy S9 & S9+ Cross Device Development] zidane02:
Thankyou so much. I do not want to wait another 7 days, is very tiring. Cheers.

i need help i an afraid.......... i continue to read but if someone can help be will be so happy !!!!!
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
You only enable it once and then go straight to download mode immediately after starting factory reset without letting it actually run and finish.

Right now, go to download mode and see if licks are off. If so, do you see Prenormal?

Let me know what you find.
[Samsung Galaxy S9 & S9+ Cross Device Development] Catpoule:
In download mode, OEM is OFF RFP is OFF. i did not see prenormal ... but it is so small .. System status is official!
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
Then try to odin TWRP. Then decide if you want to flash rom with or without root.
[Samsung Galaxy S9 & S9+ Cross Device Development] Catpoule:
Already on a rooted custom rom.but this OEM unlock button remains disable. It should be enable!
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
No it shouldn't - it is frozen by a number of the ROMs for safety. If you uncheck it, it can brick you device. Just ignore it.

PS - good luck down there - it may be another very active Hurricane season this year.

Just to clarify again:

US AND CANADA Snapdragon s9 and s9+ have locked bootloaders so no twrp and at this point even system root is unlikely.

INTERNATIONAL Snapdragon s9 and s9+ are unlockable, have working but unofficial TWRP and apparently now magisk latest beta official works.

Models: SM-G9600, SM-G9650

EXYNOS: everything works see OP
[Samsung Galaxy S9 & S9+ Cross Device Development] force70:
Yes Yes everyone knows the HK and latin america snaps are unlockable..nothing new there but he specifically mentioned AT&T so thats why i said he is locked.

There isnt anything yet engineering firmware wise out for the US/CAN versions...not like previous years. At least not that i know of and i have no need to search for it anyway lol, i have exynos.
