Cannot start the phone. Please help! - ONE Q&A, Help & Troubleshooting

Updated from CM12 to CM13, update the GAPP, system seemed to work. Then install supersu, boot to TWRP, successfully flashed. When click reboot. The phone can't start. Stuck in the middle. Can go to recovery mode though.
What should I do to fix it?
Thanks!

Why flashing SuperSU with CM 13 ?
Doesn't CM have an internal native root manager ?
Maybee you should try install CM 13 without SuperSU

Honor 8 bootloop after Magisk update

So, i just updated Magisk to 14.0. After rebooting, my phone gets stuck just before the lockscreen appears, then it automatically reboots to the recovery menu. Here i can only download a new stock rom, reboot (which goes the same way), and shutdown. Now, i would like to boot in TWRP and uninstall Magisk, but i have USB debugging disabled, so i don't know if i can access TWRP and run the uninstaller from SD.
Is there anyway i can get out of this situation without the dload method and therefore wiping my internal memory ? I have most of it backupped, but some important files i spent weeks getting are still there.
Ok, i resolved it. To fix this you can go into TWRP (pressing Power+Volume Up before the screen turns on and Up until you enter recovery) and apply the Magisk Uninstaller (it does not need a boot image to work). Hopefully this will help anyone who had this problem.
The best version of magisk yet is v13.3
mine just updated to 14.0 without any problem , i use direct update from app.
That"s what i did, too. Apparently after uninstalling i had lost root. I flashed the latest SuperSU, which caused another bootloop like the first one. To fix this one i flashed UnSU (which did nothing) and then SuperSU again (but root wasn't there)
Magisk 14, no issues here either. Stock rooted L04.

Try magisk 14.0 directly not from 13.3 , but mine is smoothly worked from 13.3.

These are weird issues. Works for one but not for others.
Strange
You can report this to the Magisk support thread.

dont install official twrp on existing twrp

Guys warning dont install official twrp on existing unofficial one it softbbricks the device i flashed fastboot rom and updated to 5.1.6 and followed the tutorial on official twrp to get it working
I just flashed the zip. I'm sure things go south of you flash the original .IMG by itself. I think you also have to reroot after flashing or you boot loop.

I literally just did. And it's totally fine. Just flashed the zip then rebooted recovery then reflashed magisk v16.0 zip then rebooted system. Zero issues whatsoever.
Where do you get oos 5.1.6?
BTW, you can flash official OTA in TWRP then just flash TWRP & magisk again afterwards.

No. I already had unofficial TWRP installed so I simply flashed the installer.
Here's exactly what I did:
1. Downloaded the official TWRP installer package
2. Hold power button, selected reboot, select recovery, tap to reboot.
3. In TWRP, confirm Lockscreen code. Select install & selected installer package swipe to flash.
4. Press home button, select reboot, select recovery, reboot.
5. In TWRP again (now official version) confirm Lockscreen code again, select install, select Magisk 16.0, swipe to flash.
6. Select reboot system. System reboots.
7. Go on XDA find this thread and say it worked fine.
8. This is where we are now. LOL
FYI... I used the unofficial TWRP provided by Zedomax (Max Lee from HighOnAndroid) originally. I didn't do all those other crazy versions.

Profit
Rooted running official TWRP 3.2.1 enchilada ??
Alright, this is a bit confusing.
Can someone tell me if I can update to official TWRP from unofficial, without losing my data/settings? The method OP describes (via fastboot) resets all my data I guess? Wish I had never installed the unofficial version....
I have this unofficial version...
I had the unofficial twrp from the very same link you posted. No problem in updating to official TWRP. Just boot into recovery, install, select the official TWRP installer (forget the img file). Reboot in recovery again, install Magisk. Reboot to system. I did not lose any data or settings (keep always a backup of your important files, you'll never know).
Thanks for the quick reply! I dared to try it and I can confirm unofficial TWRP can indeed succesfull be overflashed with the official one. No bootloops, no errors!
Phew... I had a full nandroid backup, but I do not like the hassle of going through unbricking and such....
I had uninstalle Magisk beforehand, could be the trick?
I do not know why OP was not succesful, but it seems not a problem for everyone.
This thread really should be closed because the OP is 100% not true. If you get a softbrick, it's because you didn't install the official twrp correctly. The instructions are bit involved and I see many people skipping steps because they didn't read or don't see why they need to do anything different from previous phones.
Question I updated from an unofficial version. i followed instruction someone posted on here. But since the unofficial and official look exactly same how do I know I have official?
It does work, u just didn't do it right, u can install official TWRP over unofficial.
Well, depends on which unofficial one you use(d) .
The unofficial one I used was quite laggy on first start, I had to flash some additional zips to get it working right (see the link for install process). So concerning that one: when it works fine from start, you have the new one.

update to 5.1.7

hi guys i am on 5.1.6 oos rooted twrp installed now i want to update to 5.1.7 so can i update just like that in updater app or should i have to do any prerequisites
Don't do it. 5.1.8 will be released end of next week and you will be doing this all over again. I was going to myself but I'm waiting until the next release until someone pushes full writeup and review
You can install it via the update manager. But yes, you are going to lose twrp and root, which is not a problem at all since it took me only like 5 minutes to get it all working again.
I followed this guide: https://forum.xda-developers.com/oneplus-6/how-to/guide-how-to-install-official-twrp-t3801558

Updating via twrp and then (before reboot) re flashing twrp.zip and magisk will grant you to maintain twrp and root

if u update through the OS like updater app or anything, u will have to re-flash twrp using the fastboot method, if you already have twrp installed then just update via twrp with full zip, install twrp installer zip, and then magisk (i usually reboot back to recovery after i install twrp installer then flash magisk). Then you are done, u do not lose anything and do no wipe anything either

Should i have to change slot after twrp flash of full rom
The easiest way is to download and install the update through the settings app then BEFORE you reboot open Magisk, click install then install to second slot.
No flash or worrying

Download the ota.zip, reboot to TWRP, flash ota, flash TWRP.zip, reboot to OS, reboot to recovery again if you want magisk and install magisk zip. Done. No data loss or changing settings.

Can't install Magisk 17.1 on OxygenOS Pie Open Beta 2

Just updated my phone to Open beta 2, dirty flashed it and it booted up. works perfectly fine. but after i tried to flash magisk 17.1 , it won't boot. stuck at the boot animation.
im using blu spark twrp to flash the magisk.
btw i had magisk installed on 5.1.11 and it works fine too.
any suggestions ? thxx.
UPDATE (09/12) : Issues fixed by installing the uninstaller first then install the magisk 17.1 zip. thx to exelinguy.
Try to do the whole flash procedure again.
Boot into recovery
Flash beta2
Flash twrp
Reboot to twrp
Flash magisk
Boot to system
That way it will be installed on both partitions, could/should do the trick.

Flash the Magisk uninstaller first to remove any old files, and then flash 17.1 zip again.

it depends on the situation. If you're on the Open beta updating to a newer build, the data will still be there, but if you're on the open beta downgrading a build or downgrading to oreo, your data will be lost.

When you install rom, install twrp and reboot to twrp it changes slot. If he has done it 2 times both slots are tested.

Installing twrp after having root question

Hello everyone. Is there a way to install twrp after already having root without losing all data? I tried adding twrp when i first rooted but i just kept getting stuck on recovery. I gave up and just did the root and have been like that for a while. I would like to install twrp without deleting all my data since i use this phone for work. I have a rooted tmobile on international oos with 9.5.11.gm21aa. thanks
Assuming that you rooted via Magisk:
Install TWRP, don't reboot.
Install Magisk again.
Reboot into system.

Is there a zip or how do i install it while its on? Ive only seen the adb way to install twrp. And by install magisk again do you mean using the magisk manager like when you do a ota update?
Maybe overdetailed, but all info is here:

I think your original problem was when you flash TWRP it always completes with the message;
Code:
Done installing TWRP!
*** NOTE: You are now unrooted! ***
Meaning you'll need to reflash Magisk before booting or it kicks you back to recovery. The following commands and links should get you there. :good:
Fastboot boot twrp-3.3.1-4-guacamole.img
TWRP/Install/ twrp-installer-3.3.1-4-guacamole.zip
TWRP/Install/Magisk-v19.3.zip
TWRP/Reboot/System

OK this worked great. The issue i was having before is after installing twrp i would reflash magisk through the patched boot image. Now it makes sense how it works. Thank you very much
