So I assumed that your device is unlocked? I recommend to flash twrp, more easier and works wellstart with section 2).

how did you delete recovery?
cyanogen mod forum has a good wiki on fastboot.

I don't think you did it correctly, first boot you should see the 4 icons and you need to hit the volume down button on your device (within 10sec) to select USB icon then hit the volume up button to select this setting, now proceed with the instruction on your pc to flash. Make sure you copy the recovery twrp file named" openrecovery-twrp-2.3.1.0-tf700t.blob" from here http://goo.im/devs/OpenRecovery/tf700t to the "install Recovery" folder and RENAME this file to recovery.blob

Sounds like your pc is not communicate correctly with your device. When your device is on and you execute Scott's bat file, is your device reboot into recovery so that you can select fastboot mode? Basically, Scott bat file is using adb command to reboot your device into recovery mode, you manually select and enable fast boot mode on your device, then the script is using fastboot command to push the recovery.blob (located in the same directory as Scott bat file) to your device.

And you did select the USB icon and the text displayed "fastboot" on your device? You also have the twrp renamed to recovery.blob in the same folder as the script? Let manually push this file using fastboot.exe and see what's happens.

don't trust the log from fastboot or any script. Just make sure the recovery.blog is in the same directory of the fastboot command and you must execute fastboot.exe from command prompt.
1. manually boot to fastboot mode from your device. (boot to recovery then select USB icon)
2. Open command prompt and run as admin and navigate to fastboot.exe directory (with recovery.blog in this directory also)
3. type;
fastboot.exe -i 0x0B05 flash recovery recovery.blob
4. Once done, type
fastboot -i 0x0B05 reboot
Let me know the status.

Also I would also like to point out it does not let me reboot after I write the files (using holding shift key and opening command prompt) as it freezes I think??? BEcause I can reboot from fastboot before I input writing flash recovery but after it wont allow don't know why?

Did you even notice that you didn't change to drive C: before calling fastboot? Is your recovery.blob in C:\Fastboot or in "H:\Users\Install user"?

Try this, copy the recovery.blob to this directory:
H:\Users\Install user\
Then type dir then hit enter, make sure your fastboot.exe and recovery.blob are there
H:\Users\Install user> dir then hit enter
Should show both fastboot.exe and recovery.blob
Now execute the fastboot command to push the recovery.blob

Nope, no Odin, but if your device is rooted, you could download goomanager from the market and install twrp using goomanager app.

[Q] [Problem] Cannot flash recovery

Hi All.
Hopefully someone is able to help me. I'll try to give as much information as I can.
I have followed the following guide to root my nexus 5.
I have rooted it successfully last month.
However, I have accidentally installed a OTA update from google this week (Android 4.4.3).
Just a while earlier, I have decided to flash a custom rom.
So, as usual, I reboot my phone into recovery.
However, the recovery shows the android with a red triangle, stating "no command".
I have read the forums and read that this is actually not an error but it is the default recovery for android. (Edit: Ok. Maybe its not the default recovery. Anyone able to give me advice on this?)
I guess that my recovery was returned to the stock recovery after the OTA update.
So I tried to flash CWM recovery using ROM manager, but it states "An error occured while flashing your recovery".
I decided to restart my phone and to try it again, now it stucks at 100% on ROM Manager.
I have also tried to flash recovery.img using fastboot. However, it didn't work too.
It returns with an error: "cannot open recovery.img"
May I know if anyone can help me with this problem?
More info on the current status of my phone:
Bootloader unlocked. (Checked by trying to unlock it again. System states that process has failed as it is already unlocked)
ADB Device: Detect-able.
Fastboot Device: Detect-able.

It is indeed the stock recovery. OTA returned it. It also removed root so rom manager won't work, but you shouldn't use rom manager anyway.
You'll need to download a recovery and flash it using fastboot .
Please describe the exact steps you took to get the fastboot error. Screenshot of cmd would be very helpful too please

What I did is to check if the boot loader is unlocked.
And yes. It is unlocked.
So I carried onto checking if fastboot detects my devices by doing "fastboot devices". And my nexus5 gets detected.
Then I moved on to trying to flash recovery using " fastboot flash recovery recovery.img ".
But the error appears at this point. And I'm stuck.
Is this sufficient?
Do note that I did change the file name to recovery and not recovery.img as most files do not include the file type in the file name.

Try flashing the recovery using dd (You need root)
Boot the phone normally and push the recovery.img using adb and flash it:
Code:
adb push *Path to recovery.img* /data/media/0/
adb shell
# dd if=/data/media/0/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
I hope this helps.

You would be better served setting windows not to hide known file types to be honest.
A screenshot of your fastboot flash attempt and error would be most useful please

He hasn't got root. Fastboot is his only option
Sent from my Nexus 5 using Tapatalk

Well FWIW for anyone else reading, my assumption was going to be that the OP didn't put the full path to the recovery OR didn't put the recovery in the location the cmd prompt was running from.
Would have been nice to have seen this through to conclusion, but I cannot monitor forever so I'm unsubscribing due to lack of replies.
eg:
Code:
c:\Users\Administrator>fastboot flash recovery recovery.img
If there is no path to recovery image as above, then the asumption to cmd is that the recover image is in c:\users\administrator (Which it probably isnt)
If it is on the administrators desktop you would:
Code:
c:\Users\Administrator>fastboot flash recovery c:\users\Administrator\Desktop\recovery.img

Hi. Sorry for late reply. Was at work. I'll try out the full path. What I was told is to just put the recovery IMG into the same folder as fastboot and it should do the trick. Will post screenshots after trying out.

If I gave you a few steps to try and rule out some variables to narrow down the fault are you happy to do them?
My first thing to suggest would be to take a copy of the "platform-tools" folder and drop it on the root of c: (meaning ensure c:\platform-tools exists)
Then right click Computer > Properties > Advanced System Settings (A System Properties pop up will be shown, in the advanced tab)
In the pop-up, press "Environment Variables" and in the bottom window, called "System variables" scroll down to the entry called "Path" and press edit.
Scroll to the very end of the line of text. Add the following to the end of the line with no spaces (and no quotes obviously)
";c:\platform-tools" and click OK to all windows and pop-ups. Just to break that down, it is a semi colon ; followed by the path to the platform-tools folder.
Give yourself a restart.
What this does, is gives you the ability to call the fastboot command from anywhere. So instead of typing Desktop\adt-bundle......\platform-tools\fastboot flash blah blah, you can literally just type "fastboot flash" because like other commands, it is now a system variable.
Then put the recovery.img in the directory that cmd opens up to which appears to be be "c:\users\blah"
Then open cmd and do the basic command with no paths.... fastboot flash recovery recovery.img
Let me know,
Thanks

Ah. It just worked suddenly. No idea why. But I guess @rootSU 's suggestion works well.
And maybe also @Zepius 's suggestion.
Here's what I did to help others who have the same problem.
I did what rootSU asked me to do (changing the "path" part).
Then took Zepius suggestion and duplicated the recovery img in a few folders (the original folder i'm using, on desktop, on C drive root folder)

Messed up rooting Pixel 2 XL and need some help (didn't adb pull my patched boot img)

So, I was following a rooting guide.
Things were going fine, until I needed to pull the patched_boot.img with the adb command:
adb pull /sdcard/MagiskManager/patched_boot.img
What I accidentally typed is:
adb /sdcard/MagiskManager/patched_boot.img
I continued following the guide, but when I got to the step where I need to enter the adb command:
fastboot flashboot file/path/patched_boot.img
I realized the file was never copied to my computer.
I tried to go back and install Magisk_Manager and repatch my boot image, but it failed since it now has a different boot image.
How can I fix this and properly root my Pixel 2 XL?
Thanks.

I'm not sure I'm understanding this completely. If you typed the command you said you typed (without pull in it), the file wouldn't be copied to your PC. Then you typed fastboot flash boot /path to boot.img, you'd get an error message saying something to the effect file not found. Perhaps that's how you realized you didn't type the correct command to copy it to your PC? In any case, if this is what happened, you wouldn't have a different boot image because nothing has changed. The original patched boot image should still be on the phone. Have you tried pulling it to your PC and flashing it again? That's all you should have to do unless you deleted the original patched image.

Got it all figured out now, but will post what I did for anyone else who happens to see this thread:
>you'd get an error message saying something to the effect file not found. Perhaps that's how you realized you didn't type the correct command to copy it to your PC?
Correct and correct.
What I meant to say is that when I went to flash patched_boot.img, it didn't exist, and I was worried I wouldn't be able continue at all without it.
For whatever reason Magisk was unable to repatch my original boot.img, so what I did was to:
- reflash the original boot.img
- then go back into Magisk
- patch my boot.img again
- ACTUALLY adb pull the patch_boot.img this time
- boot into bootloader
- then finally flash patched_boot.img
After this, I was good to go.
Obviously, you probably know this, just leaving a paper trail for anyone that happens upon this thread.

[HOWTO] ULM bootloader unlock and root 20e (Pie) from Oreo

Here's a simple guide for those of you like me who bought a cheap ULM G7 that's actually cross flashed from something else (Sprint for my case).
I got mine with Oreo 11e on it. I'll just explain the steps to get to unlock with 20e (Pie) rooted. I'm not an expert, but I've been doing this stuff for a lot of years. I probably can't answer questions on why it's not working for your situation, so hopefully others can jump in when necessary.
These steps worked for me. Some may be unnecessary. Not sure.
DISCLAIMER: Don't blame me if something goes wrong. Again, this worked for me.
First of all, you'll want to flash to 11g, because we have a patched rooted boot image for it.
https://lg-firmwares.com/downloads-file/17341/G710ULM11g_01_NAO_US_OP_1112
Install the patched LGUP (GUI one, not command line).
Flash 11g by doing a Partition DL, select the kdz in the bottom half (click on the first empty line).
After it's done and it reboots into the system. Let it boot, do the initial setup to get into options and enable OEM unlock and USB debugging.
Then do the unlock guide here:
https://forum.xda-developers.com/lg-v40/development/unlock-lg-v40-via-9008-root-t-mobile-t4042207
You can follow the steps in there exactly. There is nothing different that needs to be done for the G7. You're basically using QFIL to flash the v35 eng boot to get a hacked fastboot.
You're now bootloader unlocked.
Now, we want to get 20e rooted. Before we flash the 20e kdz, we need a patched boot image (Magisk). We have to create a patched boot image from the stock boot image. So, here are the steps for reference. If you want to skip this (trust me, you do), download my patched boot image here: https://mega.nz/#!uqZFDKZQ!5dOCFKElmMOXnAMel7dSvyhGY5RkJjBsMwM-kH7eOGo
Skip until you see "Skip to here".
* I was informed after that it's easier to just flash the 20e kdz, then use QFIL to extract the boot image instead of fooling around with kdztools. Leaving this for reference. *
Dowload the 20e firmware: https://lg-firmwares.com/downloads-file/21135/G710ULM20e_00_NAO_US_OP_1010
Use kdztools to unkdz, then undz:
Download the DEVEL branch: https://github.com/steadfasterX/kdztools/tree/develop
Install python. I'm using 3.8 x64 for Windows 10.
In a command prompt, run "pip install zstandard" which you need to unkdz.
In your extracted kdztools folder, run:
Code:
python unkdz.py -f <path to 20e kdz> -x
This extracts a .dz file.
Now run:
Code:
python undz.py -f <path to extracted dz file> -s 42
This extracts the boot image (you can see it's 42 if you do a -l instead of -s).
Now you have your clean/stock 20e boot image.
Go back into fastboot (if you're not still there) and BOOT the rooted 11g boot image: https://androidfilehost.com/?fid=1899786940962574205
Code:
fastboot boot 710ULM11g_rootedboot.img
It'll boot into the system and magisk is installed temporarily. Copy the clean 20e boot image onto your phone. Install Magisk Manager, then in Magisk Manager, click the first Install (top of the 2) and it'll pop up a window. Click Install again, then it'll show a menu with 4 options (honestly, the patch should be moved to the main menu imo). Click "Select and Patch a File". Find your 20e boot image and choose it. Magisk will now patch it and create a magisk_patched.img. This is your rooted 20e boot.
Skip to here.
Now we flash 20e to get Pie. Same as above, use LGUP to partition_dl the 20e kdz (select all).
Once it's done, it'll reboot. Wait for it to get to the initial setup (I don't like force rebooting while system is doing possibly important stuff). Get back into 9008 mode. Use QFIL to flash the patched boot img to "boot_a". Once that's done, just vol down + power for 15 seconds to force a reboot.
You're now 20e + root + bootloader unlocked.
I won't be monitoring this thread a lot, so don't expect quick responses, but there's enough details here for most people who are familiar with rooting to get to where I am.

I successfully rooted my crossflashed spring LG G7 using the guide you linked, and this verizon guide.
I never updated to 11g image. I manually patched the boot_a and boot_b image within Magisk GUI app, within the phone itself.
First of all, you'll want to flash to 11g, because we have a patched rooted boot image for it.

Other guides mention disabling/erasing certain partitions: the laf_a/boot_b according to this Lineage16 guide or laf_a/laf_b/boot_a & boot_b according to the 9008 guide, but I could be wrong
Code:
adb root
[In magisk make sure ‘Shell’ is granted super user access AFTER executing the following]
adb shell su dd if=/dev/zero of=/dev/block/bootdevice/by-name/laf_a
adb shell su dd if=/dev/zero of=/dev/block/bootdevice/by-name/boot_b
This will get rid of download mode feature on your phone, rendering LGUP un-useable, you can use QFIL to restore your backed up laf_a/_b files.
There's a KDZ GUI extract tool here.
It found the following in 20e kdz file: boot.img_65286, boot.img_163830; both 64MB. If anyone knows what the bolded parts represent it would be appreciated. I assume the lower number corresponds to A and the higher, is B.
I'll likely use the twrp_june.img for both boot_a/_b.
Any time you want to flash something via twrp you will have to flash twrp via fastboot again (hence the non persistance), do your stuff in twrp, and then reflash the boot img (it will not boot if you dont do this or use josh1x's boot file). Just like steps 5-6 for gapps.

Assuming you already rooted the phone, there's a way to prevent, the KDZ from overwriting patched boot_a and boot_b in LGUP, as seen 7:00 and 7:25 of the following video.
I appreciate the guide though.

Do you have download mode? If yes, you can also flash a kdz to start over. With 9008/qfil, almost all situations should be recoverable.
And what were you doing just before getting stuck in fastboot? Did you have a working system before going into fastboot? If you had trouble with the unlock process, you will have to ask in the V40 thread.

Can you patch a boot image on a phone using magisk manager if it's not rooted? I assumed you needed to be rooted to be able to patch.
If you don't, then you can LGUP directly to 20e, pull the boot image using qfil, and patch with magisk manager right after. Saves a lot of steps and time if so.

No. I rooted with QFIL and V35eng.img → abl_a (after backing up abl_a). Then did fastboot oem unlock, re-inserted the backed up abl_a.img file, then did the magisk patch up to boot_a/_b.

Maybe try a different LGUP? At worst, you can use the command line only one that bypasses checks and can force flash any kdz. But you have to be very careful to not flash the wrong firmware.
I'm not sure if QFIL can flash kdz, but you could research into that if it helps.

I flashed a firmware that I previously had flashed, ULM20e.
The phone is only recognized in fastboot as Android Bootloader Interface... Can't get anything to work, haha. However, I did get the 11g IMG to get a different screen..
Edit: The update to pie stopped at 91% and then gave an error.

Same here:
According to multiple google searches LGUP is not properly patched.
I then made the mistake of using an older version of LGUP, that doesn't give you the option to disable boot_a/_b partitions from being over written; which was a foolish mistake.
I'd like to add that Pie LG stock boot images have NO FASTBOOT support, DO NOT delete laf_a & laf_b files, doing so does away with 'download mode'. If you do delete it, you'll need QFIL to flash abl_a to v35eng.img; this will give fastboot enablement on the phone, and allow to transfer backed up files to phone using 'fastboot'.
The following post helped, in allowing me to regain access to download mode.
QFIL does not allow overwriting of Pie files except abl_a, which is more than enough in this case.
I also patched Pie/20e boot_a/_b files with magisk, and the phone is stuck in a fastboot loop for me as well, this may explain why 11g is needed.
If using LGUP 1.15, you'll come across google link by sarang on how to implement the 'common dll' patch. Forum won't let me link to the website.
Installed 11g after changing to LGUP's program files (x86) directory:
Code:
lgup_cmd.exe com[your com port # in windows device manager] "C:\Program Files (x86)\LG Electronics\LGUP\model\common\LGUP_Common.dll" "E:\HIS Documents\Computer guides\LG G7\Softwares\G710ULM11g_01_NAO_US_OP_1112.kdz"
I'm finally able to boot into Android 8.x now, and make magisk fully root.

Qfil allows backing up files as well as overwriting almost any file. I do it all the time.
Bricking my phone along the way trying different things. Unlocking and relocking bootloader.
Most of the time when you patch boot imgs people patch and load the magisk patched image to the wrong slot.
I have crossflashed the Korean pie and updated to Android 10 and achieved root with Android 10 as well.
All with qfil and using the command line LGUP to crossflash.
I don't mind helping users with issues as well.

Does anyone know the cmd syntax to execute the following? I.e. 'partition dl' is selected, and every partition but boot_a/_b is selected for installation. LGUP 1.15 GUI asks for a login making it un-usable for most on here.
Edit: This post may correspond with using the right version of LGUP.
I googled parts of this video: https://www.youtube.com/watch?v=ylBSZk7EqcA
I was able to reach 100%.
Unfortunately there's a boot loop, it seems 710ULM11g_rootedboot.img must be flashed before transferring file with LGUP.
I'm stuck and totally confused. Flashed 710ULM11g_rootedboot.img before transferring G710ULM20e_00_NAO_US_OP_1010.kdz. I then pressed power and Vol Down, then tapped the power button, click No on the white screen background, and again, I'm stuck on the fastboot loop.
The fastboot menu looks different than that of the video
https://www.youtube.com/watch?v=ylBSZk7EqcA
The one in the video looks like it's from v35eng.img used in 9008 QFIL guide.

Go back to ULM11g and crossflash using lgup command line to 20e then root it.
I believe there is a rooted 20e boot img that you can load with qfil or if adb fastboot works.
Crossflashing:
https://forum.xda-developers.com/lg-g7-thinq/how-to/cross-flash-oreo-pie-firmwares-lg-g7-g7-t3915303
Using qfil to load rooted 20e img.
https://forum.xda-developers.com/lg-v40/development/unlock-lg-v40-via-9008-root-t-mobile-t4042207
The process in the second guide is the same when loading a rooted img to either boot a or b whatever slot your on.

I was able to solve it.
The magisk patched IMG file by this OP was flashed to both boot_a and boot_b, then executed 'fastboot reboot'; yeah boot_a and boot_b need to be flashed with an identical file.
https://mega.nz/#!uqZFDKZQ!5dOCFKElmMOXnAMel7dSvyhGY5RkJjBsMwM-kH7eOGo
The screen booted twice with the 'Red LG symbol" showing itself twice, before I could get in to the new user setup prompts.
The 20e patched file from the following thread was no good:
https://forum.xda-developers.com/lg-g7-thinq/development/magisk-18-0-boot-images-t3955096
The most important part of this upgrade is definitely making sure LGUP is setup properly, including not installing the stock 20e boot_a/_b partitions, as seen in my previous post, and don't delete the laf_a/_b partitions as a good precautionary measure.

Yes the boot imgs are identical they are labled a and b because of the dual slots. If you knew what slot you were in prior to flashing any magisk rooted image you would just need to flash that specific boot img slot.
I relocked my bootloader just for kicks.
If you can get into fast boot there is no need to erase laf partitions only if you need fast boot.

I tried it but didn't work in EAW and I lost serial number mac address how get them back??? Need urgent help please

mine was already bootloader unlocked,
but tutorial worked fine here I flashed 20e using LG up and rooted.
What I did:
MAKE SURE YOU ARE BOOTLOADER UNLOCKED. I am not responsible for any damage, it is only what I did.
1)Dowload the 20e firmware: https://lg-firmwares.com/downloads-file/21135/G710ULM20e_00_NAO_US_OP_1010
2) Download this: LGUP new version - https://drive.google.com/file/d/1dJZxrj7nteDDUcQpiJLpX9Mjumm5mtKp/view
3) Install the file you downloaded above (LGUP).
4) Download this: LGUP common.dll https://drive.google.com/file/d/1V8IF2vJed3bQBsBCHLNBJdnW4gRj2uo0/view
5) Open the file downloaded and you will see the folder common. Copy the folder common and paste inside the folder model of the folder of the installation of the LGUP. For example: C:\Program Files (x86)\LG Electronics\LGUP\model
6) You are doing great! Congratulations. Let's proceed with 7.
7) Get phone in hands. Turn off it. Press and hold volume up and connect the phone into notebook. once appears download mode panel you unhold volume up softly.
7.1) When you connect the phone in download mode LG device must show in Windows Device Manager under "Ports" as a LG Serial COM port. Check it.
8) check if you completed the download of the kdz file. Did you complete the download of the big KDZ? Put the KDZ file in C:\ localization of your computer.
9) Let's open a command prompt as administrator. Now, in the command prompt input, type:
cd <path of LGUP folder>
Example:
cd C:\Program Files (x86)\LG Electronics\LGUP
10) Is your phone com5? check in Device Manager under Ports. It is written COM and a number after. If the answer is yes, you only have to type this code and run in the command prompt:
lgup_cmd.exe com5 "C:\Program Files (x86)\LG Electronics\LGUP\model\common\LGUP_Common.dll" "C:\G710ULM20e_00_NAO_US_OP_1010.kdz"
11) Are you unsure if your phone is com5? just modify com5 to comX replacing X with the properly number. For my EMW worked with com5.
lgup_cmd.exe comX "C:\Program Files (x86)\LG Electronics\LGUP\model\common\LGUP_Common.dll" "C:\G710ULM20e_00_NAO_US_OP_1010.kdz"
12) Wait 5 minutes, less or more.
13) it is completed! Remove the plug of the device.
14) It is like a new phone you have to conclude the phone configuration.
15) install magisk from magisk website but dont update it.
16) Get developer options enabled in your phone.
17) Open command prompt as administrator, type this code:
cd <path of minimal adb and fastboot folder>
Example
cd C:\Android-FastBoot-Adb
Don't have adb and fastboot minimal folder? Research in google and download. If you don't know what is the folder, it contains fastboot.exe inside.
18) Type this code now: adb reboot bootloader
19) confirm in phone allow usb depuration in this device or the command wont work
20) Download in your windows this pre rooted file made for this PIE OS by the author of the thread
https://mega.nz/#!uqZFDKZQ!5dOCFKElmMOXnAMel7dSvyhGY5RkJjBsMwM-kH7eOGo
21) put the file inside the fastboot folder. the file name is g7_20ulm_20e_boot_magisk_patched.img
22) in command prompt (already in cd path of minimal fastboot folder) type this:
fastboot boot g7_20ulm_20e_boot_magisk_patched.img
23) phone will reboot.
24) now phone started, open magisk and update it and click to install directly when it asks.
25) magisk will ask to reboot, click to reboot you are now rooted.
good luck

Hi Just a lost soul passing thru Lol
I'm looking to shed some light on my g710pm, its been a few days since I've been searching to get on AOSP.
I cross flashed to ULM 11g stock and had root and unlocked bootloader, then flashed 21d ULM and now Enable OEM unlock is grayed-out (bootloader is already unlocked ) sub message. SO... I back flashed to ULM 11g with same issue.
I've been reading the forums and have a rough idea how to fix, some how re-flashing laf_a ?
would really appreciate the help
Thanks

its patched magisk for mediatek devices, using other version of magisk for patching boot file results in bootloop

hm.. I have Xiaomi Redmi 6 it doesn't boot-loop. but I have other issue. will try...
nope! same issue as on any magisk. but this one does not even give root. Do not link that apk without note what exactly is "patched" - it's not recommended!
Code:
cereus:/ $ su
No daemon is currently running!

You have missed something, it definitely works and the issue you have mentioned isn't related to this thread, if its caused by magisk then try other rooting solutions.

I just proofed that (outdated) patched alpha apk isn't working for my mediatek device (doesn't give root), furthermore the official stable apk doesn't boot-loop my mediatek device.
https://github.com/topjohnwu/Magisk
yes, my linked issue is unrelated. but you can find magisk logs there, proof that canary is working.
So if Magisk boot-loop for you, obviously you are the one who has missed something (maybe checkbox for preserving encryption?)

Did you tried with steps mentioned in this thread ?
If yes then, if you read this command,
Code:
python mtk w boot,vbmeta boot.patched,vbmeta.img.empty
Here the boot.img is named boot.patched to avoid unpatched boot image to be flashed on device
Did you renamed patched boot.img as boot.patched ?

my bootloader is unlocked already, so I just flashed magisk_patched_23001.img from fastboot. as you can see in post #4 su respond with No daemon is currently running! so obviously magisk is somehow present.
Maybe I should delete /data/adb next time trying older Magisk. but baseband unknown occurred regardless of su daemon was not running, therefore I have no interest in this v23 alpha build anyway.
But thx for trying to help me

you can easily fix unknown baseband using twrp

you mean patching fstab with nvram nvdata nvcfg? how can I do this systemless? or do you mean I should patch twrp.fstab? thought that is only used for recovery mode.

You need to delete a certain files in a directory in root file system it works well in android 10 and above

what? magisk is systemless-root method. I won't touch anything inside system partition for sure (I would just use Magisk systemless REPLACE function if you tell me what exactly files must deleted?) But my baseband is working fine on normal boot, just when booted into Magisk baseband disappears. Have you even read my issue on github (linked in post #4)?

Bro i know what circumstances you have here regarding magisk, but why are u using alpha build if you can use the normal apk? And what android are yoi?
Regarding in unknown baseband you can try this method to fix it android 9 and up root/nvdata/nvram then delete all files inside for android 8 and lower root/nvram delete all files inside

I am using latest magisk. what is root/nvram? do you mean (rootdir) / namely /nvram? that is just a mountpoint for nvram partition. why should I delete nvram partition, as I stated baseband is working? please read the github issue first...

I just installed mentioned drivers and python .​
After that I cloned the github repo mentioned in tutorial.​
Then I did execute cmd in mtkclient folder.​
​Now I am stucked on this step where I have to connect my phone through USB with pressing vol+ & vol- buttons.
Just give me some idea about how to get through this error,
please suggest me solutions for this error.

Please help me with the preloader error.
While Pressing Vol+ with Vol- Buttons the Handshake failed error pops on screen.
Please Help me to fix this error.
I just want to unlock the bootloader of my rmx2117.

Please specify Android version of your phone. If drivers are installed correctly, there must COM port displayed in Device Manger on your PC

and most important, device must powered off for the handshake. if you miss it, it will powered on by usb (which is too late)
