In general, I have such a situation. Phone is loaded only with established magiskom. Now I will describe step by step all the action from the moment of purchasing the phone.
1. After purchasing the phone is unlocked bootloader paid method.
2. Update by air to 8.1 in January 2019.
3. Installed magisk 18 via rekaveri
from this post. And it rekaveri not be sewn, and launched fastboot boot command. Rekaveri stock left to be able to install updates over the air.
4. A magisk manager updated to magisk 19.1
5. After magisk manager removed magisk 19.1, select "Complete removal"
6. Reboot in fastboot mode, flashed the kernel from backup magisk command fastboot flash boot stock_boot_82c2979ce1ba920d4740c608b15780197a48d2e2.img.
From that moment the phone will not boot. If the phone is switched off and on, then boot into download mode (black screen with an inscription in the middle powered by android and at the bottom of download mode). Commands fastboot reboot, fastboot reboot-recovery is still loaded in the download mode. However, you can run any suitable recovery without the firmware command fastboot boot twrp-3.3.0-0-PLE.img, which I did. Once booted rekaveri, flashed therefrom downloaded from githaba Magisk-v19.1.zip. The phone loaded.
I did a wipe hard-reset. Flew upgrade to android pie, download it by clicking "Install". I thought that when you install this update, all sections, and overwritten by magiska nothing left. But after rebooting the phone has appeared in the center of the green robot and the word "error", then the phone will reboot and yellow lettering Your phone has been unlocker added a white label, something like Your phone has been rooted, totally did not have time to read. After that, the phone is turned off and switched to Qualcomm HS-USB Diagnostics 900E (COM3) mode.
At first I thought that my phone okirpichilsya definitively, but it managed to turn, hold the Volume + button and the power button. Phone is switched on and booted. I downloaded from the developer githaba last magisk manager, magisk 19.1, all set. Phone booted. Then in magisk manager magisk removed, first by clicking on the item "restore partitions" and then "complete removal". Phone will reboot and boot into download mode. Again, not loaded. I put magisk 19.1 - phone is loaded properly.
People, I understand that I have a problem because of the fact that magisk not completely removed. But if through magisk manager delete, alternately pressing the first paragraph to "restore partitions" and then on "complete removal", it turns out "butlup" in the download mode. Magisk-uninstaller-20190501.zip fully magisk not remove remains patched kernel. If after removing magiska to flash the stock kernel, then again butlup in download mode.
It is possible somehow fix it? How can I completely clean up the fucking magisk and update the android to 9? Maybe there are some programs that proshyut all the stick completely with all sections of the factory and the data sink iOS? And what sections modifies magisk during installation? I would like to understand what is happening and why the phone will not boot if you remove magisk to manually flash the original core
