Flashing Magisk 20.2 Bricked My Phone - Moto G4 Plus Questions & Answers

Hello everyone,
I was just casually rooting my Moto G4 Plus, but as the title says, I was unable to install Magisk on it. This is what happened:
I unlocked the bootloader and flashed TWRP 3.2.1-0. No problems at all.
I flashed the latest Magisk .zip, which is 20.2.
I reboot my phone, and the screen stays completely pitch black. Not even the "your device can't be trusted" warning comes up. The phone is bricked.
I was able to unbrick it by flashing the uninstaller. After doing that, the phone booted up fine. (Without Magisk installed, obviously.)
I noticed that the installation instructions said that "Installing Magisk for the first time REQUIRES a full data wipe."
So, I wiped my data partition and flashed the Magisk .zip again. Same problem as before (won't boot), except this time when I try flashing the uninstaller, it fails because it cannot access the Data partition (probably because I wiped it, right?)
Anyways, has anyone had this problem too? Please let me know.
Update: Unbricked by flashing stock rom. Flashed ElementalX, and then Magisk. Everything is all good now haha

Yes even i had to face same issues so flashed stock rom . There must be issues with the updated magisk build.

TWRP bootloop (even after flashing stock through LGUP)

I've decided to unlock bootloader, get a custom recovery and root my new LG G6 H870, so I've downloaded Melina TWRP v321 and Magisk v16.
Unlocking went well, then I downloaded drivers, unlocked debugging, "adb reboot bootloader" -> "fastboot flash recovery twrp.img" -> unplug usb -> boot into twrp by pressing volume down + power (with a tap) -> some weird screen about encryption popped up, but I clicked through -> and then I proceeded to install Magisk straight away, cause this guide said it'd not let TWRP stick if I didn't. After that I tried to boot into system and start the real fun. But it booted me back into TWRP. Again and again.
From there, I've tried Wipe -> Factory Reset, Wipe -> Advanced Wipe -> Repair File System for Data and System, Wipe -> Format Data, Advanced -> Fix Contents, but it all ends with twrp boot... I'm completly lost at this point. I've flashed/rooted a few phones before, but this one... it's a real nightmare.
I've also tried flashing a stock kdz (the filename is "H87011i_00_EEO_GB_OP_0108.kdz" for anyone wondering) through LGUP and redoing this stuff, but I end up with the same result. Please advise how to get it working.
Did you use uppercut when you flashed the kdz file? This is needed to successfully flash back to stock.
Seems it didn't work correctly.

Yes, I did flash through Uppercut (v1).
Since this thread started I flashed it once again, but this time I tried installing official TWRP v321. There was no weird encryption screen, but there were a lot of msgs (when installing magisk or doing a backup, for example) about being unable to unmount /system because it was being used. I did manage to install Magisk though and boot up the phone, but then when I tried installing Xposed, the phone went into another weird loop... but this time, it would get stuck on LG screen and it'd start heating up very fast. It stops heating when I restart using volume down + power into recovery. But I'm once again stuck... this is incredibly annoying, are aall LG phones like that?
How you installing xposed?
Install it via magisk module.
I had no issue.
Unlocked BL
Flashed Zefie TWRP (most stable and backups work)
Flashed fulmics
Flashed Magisk
Wiped cache and dalvik.
Reboot.
Works fine and flashed this over 15 times now no issues ever.

Did you also have that weird encryption message when flashing Zefie TWRP? Could you be more specific about your way? As in, you wiped cache/dalvik only once or after every flash? Did you wipe anything else? And yeah, I've just downloaded Fulmics and I'm at the installation screen, but I clicked System Information and it says my Storage Size is 5417MB with 104MB free... it reads SDCard Size correctly though. Should I be worried?
Starting from fresh, out the box.
Unlocked bootloader.
Installed Zefie TWRP.
Then added fulmics zip to sdcard.
Flashed zip, followed on screen instructions.
Wiped dalvik and cache.
Rebooted.
Takes a few minutes.
Boots up and done.
Magisk was packed into fulmics when installed.
I do NOT touch xposed. Too many issues plus I need safetynet for Google pay.
Yeah, I pretty much flashed stock firmware back and then followed basicreece instructions, along with flashing Fulmics, but I've got the 'official' Twp (v321). And everything's working so far, but I didn't touch Xposed so far though since Fulmics had pretty much all I wanted from Xposed. Word of advice for future readers though: don't bother staying on stock, too many problems. Fulmics is basically stock, but with some really neat options, and a ton of bugs and problems less.

[HELP] Stuck on TWRP after OTA upgrade

Hi guys,
So I tried to upgrade to 9.0.10 using TWRP method (Full ROM zip, TWRP installer, reboot recovery, magisk) and the phone keeps rebooting to recovery.
I can see the system lockscreen for a few seconds, with the "Shutting Down" message, then it reboots to recovery.
Can somebody help me?
Thank you!
The same happened to me. I think it was a problem with the encryption because TWRP didn't ask for the pin so the files were encrypted.
I just wiped all and flashed the rom again, then flashed magisk as always, and everything went fine.
Fixed it, some Magisk module was the culprit...
Mount magisk in twrp, delete modules and reboot. I was able to boot into the system, then install the modules again.

Can't get magisk to work on G4 Plus

XT1644, re-installed TWRP-flashable Nougat 7.0 stock ROM, then ElementalX (G4-2.01), then booted and installed the kernel manager to verify ElementalX was installed correctly (it was), then rebooted and flashed Magisk, and now the phone won't boot. Gets stuck on the startup flash screen and doesn't move on. I've tried Magisk 19.3 and 19.2 with same results. I'm using TWRP 3.2.3-0 installed in recovery. I've also tried installing ElementalX and Magisk in the same TWRP session, and then it won't boot at all - stays stuck on a completely black screen. Up until I verified correct installation of ElementalX, I restored stock boot image in between each attempt. Since verifying ElementalX installation I've been restoring backed-up boot image w/ ElementalX. Anyway, would appreciate any advice on how to get Magisk working. Everything I'm finding online so far just says to make sure you install ElementalX or some other kernel update first, and then Magisk will work...but it's not working that way for me.
Try flashing older zips of Magisk. I was too encountered with the same problem past 2-3 weeks ago
Curious to know if an older version of Magisk was any help.

Stock Recovery and issues with TWRP

Sorry I'm on mobile! Poor formating and typing is all my fault
So I'm out of my mind trying to fix and find a guide to fix my issues. This is how it all started
I was running the latest magisk (20.1) and OOS (9.0.17), when I installed Vance through magisk. I didn't read the instructions all the way, so I installed the module, it worked, then I saw that you can uninstall the YouTube system apk then install Vance. I deleted the Vance on my next reboot AND uninstalled YouTube system app, and I got stuck rebooting my phone. I have TWRP installed on my phone, not flashed (I didn't know the issues with TWRP when I installed the zip through TWRP). When it got stuck booting, I flashed magisk Uninstaller and it fixed the issue. I tried to reinstall magisk 20.1, and I got the same issue, stuck at boot. So I was able to go home, and use the oneplus 6t manager found here on the forums, which roots with magisk 18.0, and, it worked! But I couldn't update to the new magisk without it freezing my boot. After some deliberation on it, I decided to wipe my phone to try and fix it, and TWRP was still installed, and all my issues still persisted. After this setback, I found fastboot rom also on xda, and got it working, did an Ota to 9.0.17 from 9.0.16. Everything was working, until I went into my recovery and it wiped my phone. I don't even know where to go from here and I need help. Any and all help would be appreciated!
Edit: I just local upgraded to android 10 oos, and it seems to be fine. I don't know yet fully because I'm not at my house!

Bootloop after flashing TWRP & Root SM-T550

Hi Guys,
i lately got on old Samsung Tab 9.7 with an official Android 7 Nougar running on it.
I decided to flash twrp_3.1.0-1_sm-t550_13317 with Odin3_v3.10.7. I followed the steps ashyx described in his thread. So far so good..
Afterwards I installed SR5-SuperSU-v2.82-SR5-20171001224502 from SDCard and it prompted to reboot... now there is the problem.. It won't reboot. It says "Check failed" and I have to factory reset it. When pressing the button it boots into twrp and I can only spot red lines until it reboots with kernel binary and I'm back at the same point.
Any ideas what to do?
btw. are there any new version of twrp , SuperSu or Magisk I can use? Couldn't find any newer versions. I also search for any ROM which has the most up-to-date status (if there are any xD)
Thanks guys
Not my type of tablet but when the SM-T585 had those issues it was a wrong version of TWRP, so maybe look into that.
And SuperSU, really? That's been dead for years, use Magisk instead. It has a whole subforum here on XDA.
/edit: I managed somehow to install latest twrp and lineageOS.. but on first boot it brings up an encryption error.
"encryption was interrupted and can't complete..."
I need to factory reset the tablet... but with that i run again into a bootloop. I can't wipe "data" via twrp Error 8 was it, i think at least ^^
/edit2: I'd go with magisk... but I only find the .apk .. what do I have to flash in twrp?
/edit3:
Managed to reinstall twrp with latest verion twrp-3.5.2_9-0-gt510wifi.img. wiped all data ... Installed Magisk-v23.0 afterwards lineage-18.1-20211108-UNOFFICIAL-gt510wifi . But again.. encryption error on Lineage boot.
Problem solved.
reverted to complete stock, afterwards flashed twrp, installed magisk + lineage 18.1 + OGapps 11.0.
Now it's running.
