Can't boot any rom after flashing TWRP, help! - Samsung Galaxy S9+ Questions & Answers

Hello, i enabled oem unlock, did reboot, install twrp, boot it, installed "Disable_Dm-Verity" (not 6.0 or 6.1 which are too old but "03.04.2020" as suggested by some);
But then, when reboot, it's looping on the S9 logo! So i did reboot into twrp, wiped data & tried to install another rom : same result, wether i flash dmverity or not (tried different version).. Why?!

custom rom? try a gsi

Can't boot after 6.0 upgrade

Hi everybody.
I just flashed PureNexus 6.0 rom from 5.1.1 version, and after flashing and rebooting, the device gets stucked at the boot logo (an animation with 4 dots). This was the updating process (I'm rooted and with unlocked bootloader).
1) wiped all partitions (including system, data, etc...)
2) flashed bootloader from latest factory image via fastboot.
3) rebooted to bootloader
4) flashed vendor image via fastboot
5) flashed latest PureNexus 6.0 rom from recovery (latest twrp)
6) flashed dynamic-gapps from banks from recovery
7) rebooted
Did I do something wrong? Bootloader seems unlocked and I'm able to reboot to recovery but I don't know what else I can do.

Sounds like you did everything correct.
" Bootloader seems unlocked"
--- reboot into bootloader and it will tell you if you are unlocked.
Personally I would flash the volantis-mra58n factory image to get on the latest Marshmallow - boot up make sure all is running well.
Flash TWRP, make a nandroid, then flash the ROM.
No need to flash anything else, or at least that's what I did, here where my steps upon recieving the tablet last week.
unlocked bootloader.
flashed volantis-mra58n factory image, booted up played around for a bit (as Pure Nexus 6.0 wasn't out yet)
flashed TWRP, make a nandroid
flashed Pure Nexus 6.0 + banks gaaps
reboot, profit
sounds like something is going wrong, you should have the Marshmallow boot animation not the LP dots.
you don't need to flash the bootloader or vendor images doing my process as you are already on the latest ones from flashing the volantis-mra58n factory image.
Best of luck.

Thanks for your answer. The bootloader is unlocked, or that's what it says when I boot on it. I'll try flash to the factory image and see what happens. Thanks!
Problem solved after flashing recovery, boot.img and system.img from factory image, thanks! I'll try flashing a custom rom now.
i've read that there needs to be gapps for 6.0, 5.1 gapps supposedly won't work on 6.0

[URGENT] Phone doesn't boot after switching from H2OS V2

While H2OS was loaded, I flashed TWRP. After that I rebooted to recovery, cleared all the essential things, flashed a ROM followed by a Gapps package. After that, when I chose reboot to system, the phone stays stuck at the OnePlus logo screen. I can't access the recovery either. I flashed 3 different versions of TWRP, but still couldn't boot to recovery. P.S.: Bootloader is unlocked
What can I do now?
UPDATE: BluSpark's modded TWRP works, but after flashing the ROM nothing boots

You should fastboot flash old OOS 2 stock recovery, then full OOS 2.2.2 Rom.
Then root and install offical TWRP (not BS V41).
Then install what you want (but not Oxygen or hydrogen on MM)

oh, root access is compulsory?
Just tinking about root, because I used it to install TWRP but you're right, fastboot flash could do it

Cannot decrypt Xiaomi Redmi Note 3 (SD version)

Hello guys,
There's a problem associated with encryption of my RN 3 Snapdragon edition. Some time ago, I've officially unlocked my bootloader, to flash any custom roms I want, whenever I want (before I was using the way around it, where unlocked bootloader wasn't necessary).
OK. Back to my point, when i unlocked my bootloader, I installed Resurrection Remix rom and it was android 7.x.x I think. Somehow I was offered to encrypt my data, to have better security of my phone, etc. So I encypted it. Then everytime I turn on or reboot the phone, I was asked for a PIN code during the rom start up screen or when entering TWRP recovery. I forgot that my phone was encrypted, and I formated/deleted all possible data on my phone (internal storage, cache, etc) using TWRP and installed a fresh Lineage 8.0. Then it asked for a password on first boot, if i want to use my old data, the old password was not correct and i just chose the option to forget about old data and use it as a new phone. The phone didn't boot at all. It booted only after installing stock MIUI rom via FASTBOOT with miflash tool, and then installing the Android 8.0. But until now it shows, that my phone is encrypted in the settings menu and when i enter TWRP, it tells me the phone is encrypted and I can't see my files on internal memory and it's hard to flash the phone, as I have to use adb sideload or some other ways, but I cannot use the TWRP in normal way.
BTW, I tried factory reseting, wiping everything I can, installing official MIUI roms several times and so on, nothing helped.
If you have any thoughts please write them below, any info is important,
Thanks in advance

You obliviously choosed to "Require Pin/Password/Pattern on boot up" when setting up your pin code.
To decrypted the device, you will need to Format Data (Not wipe or Factory Reset), and flash any of following before booting the device:
SuperSU, Magisk, Custom Kernel or FED Patcher.
Thanks alot, it worked.
I've formated data, flashed fresh rom, gapps and custom kernel before first boot up from TWRP.
Reminder!
If you update your rom,
make sure also to reflash the custom kernel before booting the device.
Otherwise your device will encrypt on boot.

[Q] Can't boot into system after flashing supersu. Redmi Note 4

Hello, I can't boot my redmi note 4 snapdragon version.
I have flashed twrp recovery and without installing lazyflasher file I have reboot to system so it wasn't booting. After I found that I have to install lazyflasher for miui, I have flashed it from twrp and it wasn't working either so I have reflashed stock recovery and I was all good.
After that I have tried to reflash twrp and lazyflasher so it was working well.
Then I have flashed UPDATE-SuperSU-v2.46 from twrp. I haven't install lazyflasher after installing supersu(since I have already installed it).
After flashing supersu my phone is stuck on mi logo.
I have tried following things
* flash SR5-SuperSU-v2.82-SR5-20171001224502 (updated version of supersu) and installing lazyflasher after that.
*reflashing stock recovery , again flashing twrp (it worked earlier as mentioned above)
* I clear Dalvik/cache
*I am able to go recovery and bootloader mode.
* I don't have boot image backup
I don't want to lose my data please suggest something that will work.
Thanks.
