How to Succesfully flash the may bootloader

What you need:
ROM
VENDOR IMAGE
TWRP RC1
Verifiedbootsigner v6.1 BYCHAINFIRE
MAGISK OR SU (NOT TESTED WITH ME)
1. wipe all (system,data,cache)
2.Flash rom (MAKE SURE YOU CHECK WHICH SLOT YOU ARE FLASHING INTO)
3.flash twrp and vendor
4. flash Verifiedbootsigner
5. POWER OFF PHONE
6. boot to bootlaoder and then boot to RECOVERY.
7. REFLASH BOOT SIGNER
8. BOOT TO BOOTLOADER
9. OPEN UP CMD ON COMPUTER AND USE COMMAND BOOT (inactive slot) recover twrp.img
10. once booted into recovery flash twrp rc1 and then reflash bootsigner(force if you have to)
11. Then switch bootslots to the active one which has the rom and boot.
12. NOW FLASH MAGISK AFTER YOU BOOT
The above is my method and how i got around it, i understand i could have made the above abit more cleaner but i am in a rush and wanted to help a few fellows.
If anyone has a more detailed description of the above, please let me know so i can post.
Thanks

On step one. After you wipe system, data, and cache, your wiping the system to your active slot.the one your on. So I would say you would want to switch slots right here. So your new rom goes on clean slot.
In my experience so far after your step 5 you will have to fastboot boot TWRP again, because you just flashed a rom now and it's not signed anymore. So TWRP will not boot. Unless you have April bootloader in that slot, if you have may in both slots you will have to fastboot boot twrp. So far this is what I have had to do. I would like to know if someone has figured out how to flash a rom on may bootloader's without having to use fastboot.

Mac your right mate. I'm not sure you can do it but what I have noticed is that twrp rc1 is needed for may bootloader

[Need help]Rooting moto g4 plus in stock june security patch level.

I want to root my moto g4 plus(unlocked bootloader and twrp flashed). Anyone knows how to root moto g4 plus. And i also want to know that how to increase battery backup after rooting(is it a myth).

@ADITYA_KUMAR this has been asked and explained many times and once more.
- Take Backup
- get Elemental-X kernel (see development section and download correct one )
- flash with TWRP
- get latest SuperSU : SuperSU
- now you can follow same guide of MM from step 5 : Guide
Don't Forget to Take Backup..

How to take backup and restore it. I flashed twrp image. Before rebooting twrp works fine. But after rebooting i am not able to open twrp. I think it got removed.

What happens if you select Recovery from Bootloader ? Is it booting in Stock Recovery ?
In TWRP go to Backup and make backup of /system /data /boot.
If anything bad happens while flashing/Rooting then you can restore it.

The first time, you must open TWRP from the bootloader directly or the recovery gets overwritten.
For rooting, you can flash Magisk instead of flashing SuperSu. Other steps remain exactly the same.

This is your problem. You must open recovery from the bootloader menu the very first time. Or TWRP is overwritten with stock recovery. I don't know why that is. But that is how it is...

Reboot into bootloader.
Flash recovery - fastboot flash recovery twrp-xxx.img
Open recovery from bootloader menu (by using the volume and power buttons)
From there you can reboot and your recovery will work normally after this, most probably.

It didn't work. I flashed twrp. I opened recovery mode by using volume down to scroll to recovery mode and power button to select it. I booted in twrp mode and rebooted system from there. After that i power off my phone and tried to open twrp again, but it is showing no commands only. I didn't boot into twrp again.

Try commands,
fastboot oem fb_mode_set
fastboot flash recovery name.img
Fastboot oem fb_mode_clear
Then directly boot into recovery,
Then again boot into recovery through twrp itself (there is option for it in reboot) or try anything.

Thank you guys i successfully rooted my moto g4 plus(xt1643)

Is your bootloader unlocked? If so, you can just boot TWRP via fastboot (boot the img, not installing the zip) and dirty flash the latest OTA.
If nothing works, boot into EDL mode and use msmdownloadtool as last resort, but you will lose ALL your data in the process. Don't mess with the cable when msmdownloadtool is working or your phone is going to be permanently bricked. You should only use msmdownloadtool if you've tried everything and nothing is working, or you entered Qualcomm crash dump mode and fastboot/recovery isn't working.

Since you uninstalled SystemUI.apk, I'm going to assume you have Magisk and adb/fastboot installed on your PC.
Do you have TWRP installed? If so, just boot into it and dirty flash the latest OTA.
If not, download twrp-3.2.3-2-fajita.img here https://dl.twrp.me/fajita/ and boot into it via fastboot.
On your PC, download the latest OxygenOS from OnePlus website. move the .img you downloaded earlier to your fastboot folder, hold Vol Up + Power until you enter fastboot, back to PC - type into the search bar "cmd" then press enter, type fastboot boot "twrp-3.2.3-2-fajita.img" and press enter. Your phone should boot into TWRP, now copy the OTA file into your phone and install it into both slots (just to be sure).
You're going to lose Magisk if you do this, but you can just reinstall it and it's much better than having a $600 paperweight
Remember that you need to have a working adb and fastboot on your PC to do this.
Some tip: You can backup your data while you're in TWRP via USB mass storage, it's a good idea to do it now just in case your phone is bricked even worse than before.

He had to delete the wrong systemui apk first, with the commands you quoted
then comes those for apk installation
Code:
adb push SystemUI.apk system/app/SystemUI.apk
reboot
i never tried something like that so I dunno if it would work on all devices, or just on rooted or on no one @ all.

Dirty flashing doesn't wipe your data, but you should definitely back up your data in case something goes wrong.
If you have TWRP installed, just do what I typed on my previous reply. To make it clearer:
1. Download the latest OxygenOS for OnePlus 6T here https://www.oneplus.com/support/softwareupgrade/details?code=9
2. Boot into TWRP (Vol Up + power/Vol down + power, I don't remember which one is for recovery). If it asks for password, enter your PIN number
3. USB mass storage should now be available, you can copy/move files from your phone to PC while in this mode. It's a good idea to backup your data now if you haven't.
4. Copy the OTA file you downloaded into your phone
5. Press Install on TWRP, and select the file you downloaded earlier. It's going to take a while, don't panic.
6. When it has finished, DON'T reboot into system. Instead, go back to TWRP.
7. Press Reboot and choose the other slot (opposite of current slot, so if your current slot is B, press A. if it's A, press B)
8. Install the OTA again (This flashes stock OOS into both slot)
9. Again, DON'T reboot into system, go back to TWRP.
10. Press Reboot in TWRP and choose your previous slot.
11. Boot into system
You're not going to lose data if you do this correctly. But, you're going to lose Magisk if you do this (or maybe TWRP too). Just install Magisk again.
Don't permanently install TWRP on OP 6T because it's going to conflict with Magisk. If you need TWRP, just boot into TWRP.img via fastboot instead of permanently installing it.
I don't exactly know how to flash ROMs on A/B partition devices, but this is what I do and it works everytime. Some steps might be unnecessary, though.

Failed Update from 10.3.12 to 11 - Assistance Appreciated

Attempted to update from the latest stable 10.3.12 to 11 by flashing the full OTA zip in TWRP.
Install failed and phone locked up.
Attempting to boot to recovery or system results in Qualcomm Crashdump Mode.
I can get to Fastboot, but I'm not sure if I should try flashing twrp.img or pull boot.img from the OTA or what.
Anyone have any suggestions?

I ended up using the MSM tool located here:

Flash temporary recovery first ( lineage recovery ) then from fastboot.. boot into recovery.
You will see lineage recovery.
Select apply update - > update from adb ....
Then "adb sideload <twrp image>.img...
(probably it ask to verify choose yes)
Go back select advanced restart ( not sure the right word ) -> reboot to recovery.
Then you will have twrp installed.
If you only want to root why not flash magiskpatched image there no need TWRP just to root.

Hm but how would I install lineage recovery? Flashing recovery through fastboot doesn't work on the new devices anymore right?
I also tried booting lineage recovery without flashing but that also didn't work (although it didn't get stuck on crashdump but booted into the regular OS instead).
I did notice that it seems to be related to OOS 11 firmware. On 10 booting into TWRP works just fine and as soon as I upgrade to 11 it stops working (maybe this means it's fixable?). What I used as a workaround for now is to have 10 firmware in one slot, upgrade other slot to 11 and flash TWRP to both slots from the 10 slot. Seems to work so far but is not ideal IMO. I'm not a developer sadly but maybe someone smarter than me will come up with a solution.

What do you mean by "new device"?? New OOS version right??
I use this method all the time with oos 11.x.x.x.x to install TWRP so i can install Custom ROM later.
no need to go to oos 10 you can flash it from newest oos11.
---------------------------------------------------------------------------------------------------------------
First boot into fastboot mode.
to install lineage recovery
fastboot flash boot <lineage recovery image>.img
download from here https://download.lineageos.org/fajita
menualy select and boot to recovery. It will boot to lineage recovery.

About to give up on flashing recovery to OOS 11.1.1.1

I tried "fastboot boot" almost all of KizuYuna's .imgs, tried fastboot boot the lineagerecovery.img. All I get is the fastboot logo and the phone just restarts into OOS... TWRP is same.
About to MSM downgrade to OOS 10 to get recovery working like I did before. Thought it would be better to flash a rom from OOS 11 to get better firmware compatibility but just wont work.

Simply go back to OS 10.3.5 using the MSM Download Tool. Upgrade via OTA to 11..1.1.1, fastboot flash boot magisk_patched-23000_11.1.1.1 from XDA 235Sanders15 post. (you are now rooted with Magisk.

So you are saying MSM to 10 and then flash official 11.1.1.1 or fastboot flash boot magisk_patched-23000_11.1.1.1 (this is a full 11.1.11.1 OS flash? No need to use twrp from 10?)
Thanks

So I just went thru an Android 10 to 11.1.1.1 upgrade, and it was a bit frustrating. So I'll throw out what I learned along the way.
Note, I have a T-Mobile Variant, so sometimes you need different files/steps for T-Mo.
I flashed the full OTA via Settings > Update > Local Upgrade, which ended up boot-looping.
Via Fastboot, I did fastboot flash boot magisk_patched-23000_11.1.1.1.img; followed by fastboot reboot;
This was still boot-looping, so I shutdown the phone, and booted into recovery, which was now PBRP.
via PBRP, I flashed the full OTA again from my SDCard; then installed PBRP zip;
Reboot to System and got a Successful Boot. Yey.
Reboot to Recovery; Backup Boot.
Reboot to System
Install Magisk App; within Magisk > Install > select my Boot Backup to Patch (per Magisk instructions); I used a file manager to copy to my PC from my phone
Reboot to Fastboot; fastboot flash boot magisk_patched-23000_rJoA.img (the file Magisk created)
Reboot to System; Success!
I guess my morale of the story is, get a clean boot working, go from there. Patch your own boot, don't rely on someone else's.

So you had to go through all the trouble because you had a bootloop issue when OTA updating to 11? I already got to 11 but am trying to fastboot boot a recovery because I want to flash a custom ROM... When I fastboot boot TWRP.img or LOS Recovery .img it just shows fastboot logo and restarts the phone with no recovery shown..
