Am trying to install custom rom, using this twrp, but no matter how many times I've tried, am unable to get the phone to boot correctly after flashing rom, it keeps going into bootloop. Does anyone know how to fix?
What model is your phone?

Wonder if any of you guys might be able to help me out. Not really mentioned any where. I got a note 20. Exy. For the life of me I cannot get oem unlock to show up. I've tried the date trick. Kg status shows as normal. I'm trying to wait the 7 days I got a system update today and it rebooted. So now that's started over as I'm led to believe. If that's what's up.

Hi, i was able to flash just the patched magisk to get into custom recovery, but it seems no matter what combination i try, patched magisk + patched kernal, patched magisk + twrp, twrp in ap alone, patched magisk, patched boot, patched twrp etc, i cannot get it to boot into twrp and can no longer get into the android custom recovery because it always goes to the DID screen w bar code on the bottom or right just after rooting it'll just reboot into the os.. i believe it pretty much always passes, but it seems when i do patched magisk + patched kernal, this is only way i can get into the android custom recovery is if its plugged in.. every other time with twrp itll just boot into the DID screen.. so maybe im just unable to do the buttons/cable plug right where i have to plug unplug in a second scenario or something.. but what am i missing?

I'm stuck in a Bootloop on my SM-N986U1. I created a full backup in TWRP because I was going to flash stuff with Magisk. After creating the full backup I tried to reboot into System and it wouldn't get past the initial Samsung Logo screen (the one that tells you the phone is running unofficial software and has the Knox logo).

I tried rebooting back into TWRP and flashing my backup (even though I didn't change anything), but I can't for the life of me get back into my phone. TWRP is showing three lines at the top of the Restore that says:

E:unable to update logical partition: /system_image
E:unable to update logical partition: /vendor_image
E:unable to update logical partition: /product_image

When it gets to "Restoring System Image..." it never says that it completes, but it then offers the "Back" or "Reboot System" prompts below it. So the system image is obviously screwed up somehow and I have no idea what I am supposed to do to fix this.

If anyone can help me I would be extremely grateful as my phone is little more than a paperweight right now, and if I don't have it fixed by tomorrow I'm going to be in some hot water with my job.

When will it be updated? I have had problems using this TWRP.

I tried to install Magisk, but TWRP was blinking all the time and it was impossible, even ADB was impossible to use.
Another problem I've had, is that when I tried to go to the System, it's like the files no longer exist... all the time it was restarted to TWRP.

In case there is any doubt, my model is the: sm-n986b/ds

    just had to reflash the stock firmware to start from scratch again. root the device with Magisk, move the AP file back on the device and patch it using Magisk, then flash the device with the patched AP file. after that, I used Dr. Ketan's recovery on his website.
    I got the same problem and still not working with me
    Hello, link in 1st post to download doesn't work. Does anyone has a workaround?
