I tried the following:
1. Unlock my bootloader by enabling developer options, enabling OEM unlock, power off the device, hold VOL+ and VOL- simultaniously while connecting a USB cable, and enabling the unlock.
A factory reset was triggered as described in various tutorials.
2. I set the A50 (SN-A505FN/DS) up without Google or Samsung Details.
3. I check, wether the OES unlock was still intact, which it was.
4. I enabled USB debugging and made sure my PC was allowed to do send adb commands.
5. I typed: adb reboot [fastboot, download] (tried both on macOS, Windows and Linux, drivers were installed on Windows via Kies, Samsung Switch and the download package)
6. In the download menu I typed: [fastboot, .\fastboot.exe] flash system <various images derived here: https://www.gadgetsay.com/best-custom-roms-for-samsung-a50/>
--> failed, because the only output was < waiting for any device >
7. Powered the phone of and entered the download mode as in 1.
8. Flashed TWRP from here https://forum.xda-developers.com/t/recovery-unofficial-twrp-for-galaxy-a50-a50dd.3916199/ and later here https://forum.xda-developers.com/t/recovery-root-unofficial-twrp-3-4-0-0-for-galaxy-a50.4138313/
9. Tried to flash the GSI images => Boot loop.
10. Follwed these instructions: https://github.com/phhusson/treble_experimentations/wiki/Samsung-Galaxy-A50 => Still boot loop.
What am I doing wrong? Various tutorials and videos like this one:
indicate that it shouldn't be too difficult.
Thanks in advance for any new idea!
Additional Info: In TWRP i had to resize the system partition after flashing lineage os because it was no longer ~5GB large but rather the size of the image. Afterwards I was able to install GAPPS.
Okay, once again, the answer is "don't be stupid" or at least "rtfm". I've read online, that the A50 doesn't have an a/b-slot so I always downloaded the a-only packages. These however don't work. The very first lineage os with a "b" in the filename (as shown in the video) worked.

I have previously unlocked and modded several Xiaomi phones. However recently I got a MI8 and what I thought would be simple was quite problematic. Its solved now which is why I am writing this guide to help someone else in a similar situation. I'm not an expert but the issues I had could be relevant to other USB-C Xiaomi Qualcomm based phones from mid 2018 and later:
NOTES:
1) AMD Ryzen PC with B350 chipset would not connect in any fastboot mode procedure at all with Mi8 in my case. It could not unlock the phone or flash anything with fastboot. Go with Intel.
2) Use a good USB-C cable. One of mine worked for MTP transfers but did not work with fastboot stuff
3) If you get a request in TWRP to provide your password for decryption, this refers to the PIN used in Android security
4) If you have not unlocked your Xiaomi phone you must do this first before trying any of the steps below. There are many guides for this.
5) Follow the steps EXACTLY to avoid boot loops etc.
Issue 1: The commonly used ADB and Fastboot tools fail to flash TWRP recovery (Thanks to khanhdx https://forum.xda-developers.com/member.php?u=7791242)
1) It is necessary to use Xiaomi's specific version of fastboot in their miflash_unlock tool.
2) Put phone in fastboot mode and connect to PC.
3) Go into the miflash_unlock directory which was used to successfully unlock the phone
4) Put your TWRP image file in that miflash_unlock directory
5) While mouse cursor is in the directory, Right click while holding down SHIFT and select 'Open PowerShell session here'
6) Type 'cmd' then Enter
7) Type 'fastboot devices' to see if fastboot sees your device.
8) If a device code is displayed then USB drivers could be adequate so try 'fastboot flash recovery twrp.img' (insert actual name of img file)
9) If either no device code shows up or the recovery flash fails you will need to update USB drivers
10) First uninstall any other previously installed ADB USB drivers
11) Download Xiaomi MiFlash tool at https://www.xiaomiflash.com/ which contains drivers which work
11) Before installing the drivers with the MIFlash tool, it is recommended to boot with 'Disable Signed Driver Enforcement' enabled first. Google that if needed
12) The driver installer in MiFlash is wonky but it works. Continue to say 'Yes' to all the weird driver install warnings and long latency delays. It gets there slowly and confirms successful installation one driver at a time
13) Repeat Steps 5 through 8
14) If the above doesn't work, take a look at the driver in Windows Device Manager under Android ADB Device. It should be signed by Xiaomi not Microsoft. Also try different USB ports and/or remove other USB devices.
Issue 2: Custom ROM such as LineageOS or Pixel Experience will fail to flash in TWRP with "Error 7" stating that you don't meet the minimal Xiaomi developer firmware version requirement
1) In my case starting out with the latest Xiaomi global developer ROM and flashing the latest developer Xiaomi firmware from https://xiaomifirmwareupdater.com/#stable did not help meet the requirement and Error #7 would not go away. According to some sources such things do happen with official Xiaomi ROM's.
2) You can do the solution mentioned here https://forum.xda-developers.com/mi-8/how-to/guide-how-to-flash-poco-f1-roms-t3911336 but this is a hack and not a true solution as you will have to do this every time you update the ROM, and the phone might not work right as the dev's at LineageOS and others know what they are doing when they put in those insist lines.
3) A real solution is to meet the firmware requirement by flashing the latest Xiaomi EU weekly/developer ROM (i.e. NOT official Xiaomi) from https://xiaomi.eu/community/ before flashing the custom ROM of choice (Thanks to Xiaomi EU forums)
4) Go to TWRP and wipe everything except USB OTG option. Format data! Reboot to Recovery!
5) Transfer downloaded xiaomi.eu ROM zip file to phone via MTP and install it with TWRP. Reboot to System!
6) Allow phone to initialize it's first Xiaomi boot fully. When the MiUI welcome screen comes you can stop there. Boot into fastboot mode
7) Repeat steps in 'Issue 1' above to re-flash TWRP recovery back to the phone
8) Repeat Step 4
9) Transfer custom ROM zip and optional GAPPS zip files to phone via MTP and install with TWRP.
any reasons why this flashing and fastboot doesnt work properly with amd based pc/laptop.it is really hard for me..
There are a number of generic installation guides for custom roms eg https://www.xda-developers.com/how-to-install-custom-rom-android/
However this one is specifically for the LG G6 and tested using the US997 model. It worked for me, but I welcome comments on how to improve it.
Create a folder on the PC for all the downloads and files
Download phone driver from LG website
https://www.lg.com/us/support/help-library/lg-mobile-drivers-and-software-CT10000027-20150179827560
Download ADB/Fastboot https://developer.android.com/studio/releases/platform-tools (You need to unzip once downloaded)
(I had an error "adb server version (31) doesn't match this client (41) killing". I searched my PC and found an older version which I had used for another phone and deleted the folders and reinstalled from the download)
Ensure the phone is backing up. (Google backup is working, you have all your photos music etc downloaded) the next steps will wipe the phone
Remove the PIN/Password/Fingerprints from the phone so it will boot without any security.
Unlock the bootloader
https://developer.lge.com/resource/mobile/RetrieveBootloader.dev
The phone will then reboot and do a complete wipe so you need to wait a while for Android to setup.
Telegraph has the latest news on LG G6 ROMs and Recovery. From here I got the links for SHRP recovery which seems more up to date for LG G6 than TWRP. (https://web.telegram.org/#/[email protected])
https://sourceforge.net/projects/pa-g6/files/Releases/SHRP/20.07.2020/US997/
I named the downloaded file "recovery" (You need the .img file not the ZIP)
There are lots of active ROMS for LG G6 I have Lineage installed on another phone which works really well, but Havoc seems the most popular on the G6.
Download the ROM and Gapps https://opengapps.org/ (I used Nano, remember G6 is 64bit)
You will also need to update the bootloader. This was the latest I found for the US997
https://androidfilehost.com/?fid=1899786940962575226
(I missed the bootloader the first time and Gapps will not flash, I was helped by the LG G6 community on Telegram https://web.telegram.org/#/[email protected])
Now you have downloaded all you need
Then connect the phone to the PC and ensured you have ADB debug on in developer options and boot the phone into fastboot
On the PC open a command prompt in the folder you have all the files:
adb reboot bootloader
To load the recovery to the phone :
Fastboot flash recovery recovery.img
YOU MUST NOW BOOT DIRECTLY TO RECOVERY. Do not reboot to Android as this will automatically reset recovery to the stock version.
Unplug the USB cable and reboot to recovery (hold volume down + power button).. continue holding until phone reboots...
As soon as you see the LG logo on the screen.. let go of the power button then quickly press it again (never letting go of volume down).
Keep holding until you see the Factory Reset screen. Click thru the factory reset screens using the volume buttons to move up/down and power button to select. Choose "Yes" twice (saying you want to reset the phone it should boot into your new recovery. Despite what the screen says it won't actually factory reset/wipe your data... as long as you've installed a custom recovery and have not booted into Android since then.
Most likely you will be asked the password to decrypt the data folder. I tried my phone PIN and other default passwords suggested on the internet. I eventually found that this is a known issue and you need for cancel out of this screen and go and "FORMAT DATA"
Reboot directly to recovery (select reboot recovery in Skyhawk), this time you should not be asked for the decryption password.
I recommend you backup your current setup before making changes. If you hit issues you can use the recovery to restore. My SD card slot is broken (Poor LG design) so I plugged a USB thumb drive into the USB C slot and did a full backup. (No data since I just formatted it).
Wipe the partitions before you flash
Full wipe ("The only option you ever need")
Select Advanced and wipe system partition.
FLASH (You need to put the ZIP files either on the USB drive as I did, or copy to your SD card, or you can use ADB sideloader from the PC to push the files to the phone). The USB drive seems the easiest since you can plug it into your PC to load the files then plug it into the phone to read them.
Flash in the following order
Bootloader
ROM
Gapps
After Installing wipe cache and Davik
Reboot
It will do lots of processing while setting up. Ensure it stays cool (remove case and leave it plugged in with the screen off)
Donate to the developer of your new ROM at the end when it works.
I have been running my LG G6 on Android 10 for a few weeks and thought I would share my observations, I am using Havoc 3.7 installed with Skyhawk, I did not root the phone.
Likes : Very smooth experience, phone feel like it is running much faster. Very stable, I had one surprise reboot in the time I have used it. No issues (so far) with installing or using any apps including banking. Much lower use of storage, I have 6GB free.
Same : Battery life is about the same as before.
Gaps : Cannot encrypt, VOLTE doesn't work (which may become a big issue for T-Mobile and AT&T soon), when being used the phone gets much warmer than it did before and the wifi setting randomly turns off.
Next Steps: I am going to try Lineage which has released some fixes for the WIFI issue and report back.
I'm trying to follow the instructions as per this guide for the tmo version of G6 (H87220g) and I'm running into a roadblock on the recovery flash:
[[email protected] tmp]$ mkdir skyhawk
[[email protected] tmp]$ cd skyhawk && 7z x ../SHRP_v2.3.2_us997-233920072020.zip
[[email protected] skyhawk]$ fastboot flash recovery recovery.img
Sending 'recovery' (36936 KB) OKAY [ 1.252s]
Writing 'recovery' FAILED (remote: 'unknown command')
fastboot: error: Command failed
Click to expand...
Click to collapse
I downloaded the Skyhawk zip from the PA download link, unzipped it and used the recovery.img file found inside the zip as part of the fastboot command. Is this incorrect ?
Yes, you need the recovery.img file to flash via fastboot. Have you successfully unlocked the boot loader? You cannot replace recovery without unlocking.
You also need to ensure you have the appropriate files for your phone I have a US997 but as you have H872 you would need skyhawk for the H872 in the notes above you are still using US997.
bootloader is unlocked as per:
https://forum.xda-developers.com/tmobile-g6/how-to/unlock-bootloader-tmo-t3578099
fastboot flash is failing and I'm not the only one it seems like based on comments here and reddit...
I gonna try out @runningnak3d guide and see if that works...
This guide is for the US997. The H872 has a much more complicated process to install recovery : https://forum.xda-developers.com/tmobile-g6/how-to/root-h872-to-including-11g-t3775518

my sister is very grateful
Thank you very much.
What build date has this rom? Sec. patches?
Can you please post your local manifest?
Very interesting guide, unfortunately the links don't work...
Is it possible to restore them?
Tanks. Max
I think its first guide how to do it because every other guides were for TB2-X30F but not for TB2-X30L.
I have only found lineage os for x30l, can someone please link lineage (Android 7) for x30f?
The difference between L and F is that L is the sim card variant. Ive read several people getting "insert sim card" when installing L on a F tablet. So I dont want messages like this.
Thanks for this tutorial. It was possible, to upgrade this old Tablet.
Do you know, if there is anything newer version for our Lenovo?

I have followed the instructions and successfully installed LiOS14. Then, however, I have factory reset the tablet via Settings. Now it always boots to TWRP, no matter what I have tried I could not installed back the LiOS14 I only have TWRP right now.
Any help?

The tablet can also run on LineageOS 16 which is Android 9.
As I saw that the guys in the Russian 4PDA-Forum had been able to create a LiOS16, I was able to make some adjustments and compile a ROM with most recent security patches which now runs on my good old TB2-X30L / TAB2 A10-30:

Hallo,
I have installed LiOS14-UNOFFICIAL-TB2-X30L.zip. The installation was without problems.
But I am having problem with WiFi - problem of MAC 02:00:00:00:00:00. I have tried a lots of tips but nothig worked. Two times I was succesfull to set some MAC, but always, after while, it was gone. No able to reproduce to set.
Is it really so difficult to set somehow the MAC addres for the WiFi?
As I understand the setting of the MAC differs between different releases of OS. Does anybody know how it work in this release? It should by known where this relaese expects the MAC setting. Am I right?
1. temporary succes: Setting MAC in system/etc/firmware/wlan/qca_cld/wlan_mac.bin (I think. Its longer time ago and there was more attempts). It lasted for few months. It is not mine device so I don't know how it was handled.
2. temporary succes: I copied system/etc/firmware/wlan dir to system/vendor/firmware/wlan. I did it based on how it is in Samsung Galaxy S4 mini with Lineage 16. It worked. After restart I had to swith off and on the airplane mode to set MAC. After few attempts it was gone. No able to reproduce to set the MAC.
I am not Linux expert

As I saw that the guys in the Russian 4PDA-Forum had been able to create a LiOS16, I was able to make some adjustments and compile a ROM with most recent security patches which now runs on my good old TB2-X30L / TAB2 A10-30:

Thank you very much, install your rom on my TB2-X30F and it goes very well, the only drawback that I present is that the wifi is very slow but the rom is excellent, thank you very much for your work.

Will this work with x30F?
Hi All,
With the recent launch of LineageOS 18.1 I decided to take the plunge and get it installed on my fully stock Videotron/Freedom H915. Since I had to smash together info from a half dozen other threads, I figured I'd gather it all together here for folks with a Canadian phone trying to make this work.
Since I knew absolutely nothing coming into this, I'm going to go a little more detailed on this write-up. If you've been flashing ROMs since the old days of Cyanogenmod you can probably skim half of this.
Disclaimer : I'm not responsible for any bricked phones or other negative outcomes. This is what worked for me, but I'm far from being an expert. If you continue past this point you agree to take your time, do your reading, be responsible for your own device/actions and not hold me or the forum accountable for anything that might go wrong. You've been warned.
IMPORTANT NOTE #1
If you've picked up an H915 on ebay and you are intending to use it on a network other than the one it's SIM locked on, make sure you do the whole SIM unlock process on the stock ROM either before you get started at all, or once you've reverted to the vulnerable stock ROM after Step 1 below.
I actually use Telus as my provider and I wasted a bunch of time trying to figure out why I couldn't get signal because only the stock ROM will prompt you for a SIM Unlock code. Lineage will just sit there dumbly and not allow you to enable data.
Once you've unlocked the SIM it will stay unlocked from that point forward, just make sure to unlock it and verify your SIM is working with LTE on the stock ROM before you get started.
IMPORTANT NOTE #2
Use LGUP's "DUMP" feature to take a backup of ALL partitions on your phone before you start. If you're reading this thinking "I just bought this phone off ebay, there's nothing on it I care about", take the backup anyway. You never know when you might need a copy of the modem partitions or other things from your phone's original build. It came in super handy for me in troubleshooting the process. So go do a backup!
Current Issues:
If signal is too weak to connect to a tower (or non-existent), the OS tends to crash with a modem error. Still trying to figure this one out.
I think I can get this working without first jumping to US996 but haven't had a chance to verify that. If I do I'll update the thread.

Different Boot Modes
For those not familiar with these phones, there are three different "modes" the phone can boot into. Here's a quick reference on how to boot into each one.
Download Mode
This mode is used for pushing KDZ files or individual partition backups using LGUP
Turn Off Phone
Hold the Up-Volume Button
Insert USB-C Cable with other end already plugged into PC
Bootloader (aka Fastboot) Mode
The H915 doesn't come with this mode by default. If you try it, you'll just get battery charging. We'll be temporarily converting the phone to a US996 in order to use the DirtySanta exploit to replace the bootloader partition with a leaked Engineering aboot.
This mode is used with the fastboot tool to load the TWRP utility into the Recovery partition.
Turn Off Phone
Hold the Down-Volume Button
Insert USB-C Cable with other end already plugged into PC
Recovery Mode
The recovery mode on a stock phone is used to perform a factory reset. We will be using the Factory Reset a couple times with the stock ROMs, then replacing the contents of the recovery partition with the TWRP tool that allows us to format partitions, load partition images, and sideload apps and LineageOS itself.
Turn Off Phone
Hold the Down-Volume Button
Press and hold Power-On (rear fingerprint sensor/button). When LG Logo appears, release power button for 1 second then press and hold again
When "Factory Data Reset" appears, release all buttons
Press Volume Down to highlight "Yes" then press power button to select the option
Repeat for the confirmation
Note about flashing KDZ files using LGUP
You can flash KDZ files onto the phone using LGUP from two places - either with the phone in "Download Mode", or with the phone booted into the OS with the USB Options set to "File Transfer" and USB Debugging turned on.
The difference between these two is when it performs the OS compatibility check.
In Download Mode it's the code of the Download Mode partition that does the check. In the OS, it's the OS that does the check before booting to Download Mode and bypassing Download Mode's check.
Why is this important? Because when converting from one phone to another (Say, an H915 to a US996 like we do below), you initially can't flash the KDZ using LGUP's "Upgrade" function. You can only use "Partition DL" to replace the contents of partitions with the contents of the KDZ. This kind of works, but ends up with a phone that will sometimes identify as a H915 (in Download Mode) but sometimes identify as a US996 (in the OS). To clean it up, once you've done the Partition DL method, you can do it again from the OS and use the Upgrade method to get a really clean install.
It works going back the other way as well when you want to return to stock.
If this doesn't make sense, don't worry. You don't need to fully understand it to follow the instructions below, I just found it to be interesting info that didn't seem to appear in other threads.
Process Overview
Revert the phone to an old/vulnerable stock Nougat ROM for Videotron/Freedom Mobile
Enable Dev Options
Dump contents of US996 KDZ partitions over top of existing partitions
Cleanup by re-flashing US996 KDZ partitions over top of existing partitions
Transfer files to the SDCard and install Terminal Emulator
Unlock the Bootloader using the DirtySanta exploit
Boot to old TWRP and install new TWRP
Boot to new TWRP, install LineageOS, Google Apps, and flash modem partition image
Reboot to LineageOS
Actual Process
1 - Revert the phone to an old/vulnerable stock Nougat ROM for Videotron/Freedom Mobile
We need to be on Nougat for this to work, so if you're on Oreo you have to downgrade to Nougat before we begin. I chose a Nougat ROM for the H915 that's vulnerable to the DirtySanta exploit because I know it works and because I'm hoping in the future to be able to skip converting the phone to a US996 if possible.
Boot phone into Download Mode
Launch LGUP with Patch
Select "Upgrade" radio button
Select bin file : H91510e_00_VTR_CA_OP_1205.kdz
Click Start
When finished phone will reboot
1.5 - Do this if Step 1 Failed... Otherwise continue to Step 2
Depending on what's loaded on your phone when you start, it might complain about doing Step 1. This should allow us to bypass the issue and allow Step 1 to work. You can use this step if you've already converted the phone to another model as long as it's not bricked.
Boot phone into download mode
Launch LGIP with Patch
Select "PartitionDL" radio button
Select bin file : H91510e_00_VTR_CA_OP_1205.kdz
Click Start
Click the "Select All" partitions checkbox and click OK. When done it will reboot.
If it hangs or loops on reboot, boot into "Recovery Mode" (which at this point will Factory Reset the OS)
The phone boots into the OS
Quickly go through setup wizard. Skip as many things as possible.
Go Settings - General - About Phone - Software Info - Make sure it identifies as H91510e
Change the USB Option mode to "File Transfer"
Then repeat Step 1, but from inside the OS instead of in Download Mode
2 - Enable Dev Options and File Transfer Mode
We need these enabled after every time we flash the OS so that our LGUP and adb commands will work. You'll get used to doing these steps a bunch.
Quickly go through setup wizard. Skip as many things as possible.
Unplug USB-C cable
Swipe down from the top and change from USB Charging mode to File Transfer mode
Settings - General - About Phone - Software Info
Tap on Build Number many times until it unlocks Developer Mode
Go back 2 menus and enter the new "Developer Options" menus
Make sure "Enable OEM Unlock" is enabled
Enable "USB Debugging" (will be greyed out if USB-C cable is still attached)
Go back to main screen
Plug USB-C cable back in.
A pop-up will appear asking to Allow USB Debugging. Check the "Always Allow" box and tap OK
3 - Dump contents of US996 KDZ partitions over top of existing partition
The Videotron/Freedom KDZ has no Bootloader/Fastboot mode. If you try to enter bootloader mode you'll just end up charging the battery. So we have to cross-flash the US996 KDZ to get a phone with a bootloader which we can then replace with the engineering version using the DirtySanta exploit.
Boot phone into download mode
Launch LGUP with Patch
Select "PartitionDL" radio button
Select bin file : US99610f_00_1205.kdz
Click Start
Click the "Select All" partitions checkbox and click OK
When the phone boots back into the OS, repeat all of Step 2.
Note: If it asks for a password on startup, follow the "Boot to Recovery" steps and since
we don't have anything loaded in the recovery partition it will wipe/erase the phone
and remove the password.
4 - Cleanup by re-flashing US996 KDZ partitions over top of existing partitions
As mentioned in the "Note about flashing KDZ files using LGUP" section above, after you use the PartitionDL method you get a kind of dirty phone image that doesn't always identify as its new model. To clean up, we repeat the process in Upgrade Mode, taking advantage of the fact that at least the OS now identifies as US996 even if Download Mode doesn't. After this, Download Mode will also identify as US996.
Starting booted into the OS with a USB-C cable attached (File Transfer mode, USB Debugging on):
Launch LGUP with Patch
Select "Upgrade" radio button
Select bin file : US99610f_00_1205.kdz
Click Start
When the phone boots back into the OS, repeat all of Step 2.
5 - Transfer files to the SDCard and install Terminal Emulator
We will need some files on the SDCard in the phone in order to install them, either inside the OS (in the case of Terminal Emulator), or later on from TWRP. The Terminal Emulator will be used for the DirtySanta exploit so we need to get that installed now.
Make sure the USB Connection is set to Data Transfer mode and copy the following files to the SDCard:
APK for Terminal Emulator
twrp-3.5.1_9-0-us996.img
h915freedommobilemodem.img
Enable installing apps from unknown sources by:
Settings - General - Fingerprints and Security - Unknown sources (turn it On)
Install Terminal Emulator:
Tools - File Manager
Choose "Allow" when prompted
Click the up-arrow next to "Internal Storage"
Choose SD Card
Scroll down and tap on jackpal.androidterm-1.0.70-71-minAPI4.apk
Install
6 - Unlock the Bootloader using the DirtySanta exploit
The US996 KDZ has a bootloader but it's locked. In order to unlock it we need to use the DirtySanta exploit to give us permissions to replace the Bootloader/Fastboot with a leaked engineering version.
Starting booted into the OS with a USB-C cable attached (File Transfer mode, USB Debugging on):
Settings - General - About Phone - Software Info
Verify that Software Version lists as US99610f
Copy the twrp-3.0.2-1-us996.img file into the folder containing the LG V20 Root Package
Open a command prompt window and change to the folder containing the LG V20 Root Package and run "Step1.bat"
It will push multiple files to the phone and apply some patches/exploits.
This proces will take 5 minutes and put you out at an "elsa:/ $" prompt
At this "elsa:/ $" prompt in your command prompt window type the following:
run-as con
chmod 0777 /storage/emulated/0/*
On the phone, launch Terminal Emulator and run the following:
id
Verify that the string which comes back contains the string "context-u:r:untrusted_app".
If not, run Step1.bat again, else continue forward
Enter the follosing command into Terminal Emulator (be very careful to type it properly):
applypatch /system/bin/atd /storage/emulated/0/dirtysanta
If that command came back with an error, close and re-open Terminal Emulator and try again
The command should begin to patch another file. This will take 5 minutes and will return you to the "elsa:/ $" prompt in Terminal Emulator when it has finished
Open another command prompt to the same folder and run "Step2.bat"
This step will download backup copies of the boot and aboot partitions from the phone then boot the phone into bootloader/fastboot mode.
You'll know it worked if the first line at the top of the phone screen appears in red
In the command prompt window, run Step3.bat
It will flash boot1.img and the TWRP Recovery image multiple times then restart the phone
The phone will hang, no matter how long it's left. Wait 5 minutes (at least until the logo re-loads once) then do the following:
Unplug the USB-C cable
Remove the battery from the phone to turn it off
Replace the battery
Boot into Fastboot mode and run the following commands in your command prompt:
fastboot flash boot bootbackup.img
Remove the USB-C cable and battery to turn off the phone. Then replace the battery and enter Recovery Mode
The phone will show a big red exclamation mark saying "Your device is corrupt". This is normal. It will go away after a few seconds then boot into recovery. This error screen is the result of the engineering "aboot" image that was flashed to give us an unlocked bootloader and will always happen on boot.
7 - Boot to old TWRP and install new TWRP
The old version of TWRP recovery will load. Don't ask me why we can't just go straight to new TWRP above, it didn't work well when I tried it.
If it asks for a password to decrypt data, click Cancel
Swipe to allow modifications
Install - Select Storage - MicroSD Card - OK
Install Image - Scroll down and tap the "twrp-3.5.1_9-0-us996.img"
Select the Recovery partition and swipe to confirm flash
Back to main menu
Reboot - Recovery
8 - Boot to new TWRP, install LineageOS, Google Apps, and flash modem partition image
The new version of TWRP will load:
Check the "Never show this screen during boot again" box
Swipe to allow modifications
Wipe - Format Data - type "yes" to continue
This is likely to fail the first time. Repeat it to properly format the data partition.
Go back to Main Menu - Wipe - Advanced Wipe - Select "Dalvik / ART Cache", "System", and "Cache"
Swipe to wipe
Back to main menu
Advanced - ADB Sideload
Plug in USB-C cable
Swipe to start sideload
In command prompt window on PC type the following:
adb sideload lineage-18.1-20210506-nightly-h910-signed.zip
When complete tap "back" and "ADB Sideload" and swipe again to apply another file:
adb sideload MindTheGapps-11.0.0-arm64-20210412_124247.zip
If you want to root the phone (completely optional, not necessary for this process), now is the time to do it. Tap "back" and "ADB Sideload" and swipe again to apply another file:
adb sideload Magisk-v23.zip
Go back to main menu - Install - Install Image - tap the h915freedommobilemodem.img file
Select the Modem partition and swipe to confirm flash
Remove USB-C cable
9. Reboot to LineageOS
Go back to main menu - Reboot - System - Swipe to reboot

thank you so much. i need it
Great job for writing a complete how-to guide!
Thank You, You saved my old V20 H915
hi have you been able to find a better modem?
btw i'm not able to decrypt under twrp, can you?
Just want to confirm, it's only guide wich works for me. But I have issues with modem:
1. When I tried to change mode of modem, "prefered network type", phone stayed in the loop of the kernel panic "modem crash"
2. It were difficult to revert changes back. Finally, safe mode (in order to get it, you need to press volume up and volume down in the same time, during LinageOS booting process) helped me - when I disabled airplan mode, I had 2-10 seconds until next kernel panic. And in ~10 attempts, I were able to finally switch modem's mode to GSM/WDCMA/LTE
3. I used this phone 3 days, and once the kernel panic (because of modem) happened again
Any ideas what to do with modem? Also, the picture "Your phone is corrupt" is not fan Any ideas how to change it?
I did my best to follow all the instructions but after step 7's reboot I just get blocks full of static. I can tell it's trying to do fresh install setup though from what's peeking through the blocks.

This is normal. Flash a kernel that's patched for dirty santa OR, cover the proximity sensor on boot and keep it covered until boot is complete.
That worked, thanks.
After multiple attempts going back and forth with step 6, I finally did it! I might switch to Lighthouse or Arros but I wouldn't have gotten this far without your guide.
N200 on OOS 12, can't seem to possibly ever enter fastboot mode. Whenever I try I get some screen with the only options as wipe device, reboot, power off and 'fastboot devices' on my computer no longer shows the phone. Also there is no longer an 'advanced reboot' option in OOS12 so I can't go that route either. Please help so I don't have to bin this thing
Looks like you're in recovery mode. Remember that you have to shut down your phone and hold both volume buttons and the power button while it's unplugged to enter fastboot mode. Alternatively, you can use the "adb reboot bootloader" command while your phone's booted up.
Also, you can't install LineageOS from OxygenOS 12 right now. You need to downgrade to the last version of OxygenOS 11 before installing a custom rom.
Hi, thank you for responding! I've dug in further and what's going on is the driver doesn't work in Windows in fastboot mode, only in ADB does the driver work so I am sort of stuck. I downloaded the OOS 11 zip but I can't figure out how to install it now, I don't have a 'System Update' area in settings that will let me apply the local zip. My update screen just says 'you are up to date' and gives no option to apply a local update. Any idea how to get to the local update setting to apply the OOS 11 zip? Thanks again!
EDIT: I've found a couple of applications that restore the 'local update' feature but now it either says verification failed (My Application2 app) or else the local update file is not shown (OPLocalUpdate_For_Android12.apk). I downloaded this file and put it in the root of the internal storage but it's not working:
NordOxygen_14.I.25_OTA_0250_all_2201171943_downgrade_347e133266814951.zip
Is this the right downgrade file? I have an N200 global. Thanks!
Edit 2: I'm now back on OOS 11! Yahoo! I used the guide here:
Downgrade US OEM (DE2117) Android 12 firmware to Android 11 BEFORE installing Lineage!
Lineage installation on N200 REQUIRES that you are running Android 11 or phone will soft loop after installing the Lineage boot.img If you are updated to Android 12 firmware and want to install Lineage, you MUST downgrade first to: DE2117 OEM...

Back to my original issue though, I seem to be having driver issues with fastboot mode. I've tried a few USB ports & cords to no avail, do you have any thoughts on troubleshooting a fastboot problem? The device shows normally when plugged into Windows but when I do 'adb reboot bootloader' and the handset enters fastboot mode then I lose the driver and instead the device shows up under 'Other devices' as 'Android' with a yellow exclamation point. I tried installing OnePlus_USB_Drivers_Setup.exe but that didn't do anything, do you think I should boot Windows with driver signing disabled and try again?
You can usually force the OnePlus fastboot driver to install. I don't remember the exact steps, but I think that you have to right click on "Android" in Other devices, select Update Driver, select "Browse my computer for driver software", select "Let me pick from a list of device drivers on my computer", select the Android related category, and select Android Bootloader Interface. Accept all warnings.
If that doesn't work, you could also try the universal ADB driver, as that's what LineageOS recommends.
You probably don't need to disable driver signing.
Thank you for the replies, I was able to get the driver installed and I installed lineageOS per the offficial doc. Unfortunately I seem to have bricked the phone as it's stuck in fastboot mode and won't boot into recovery anymore
What I did was from here:
Install LineageOS on dre | LineageOS Wiki
wiki.lineageos.org
a) fastboot oem unlock
b) boot into custom lineageos recovery via fastboot - fastboot flash boot lineage-19.1-20221116-recovery-dre.img
c) sideload in copy-partitions-20220613-signed.zip
d) install lineageos
Any idea how to get recovery working again?
EDIT: I think I should specify this is an UNLOCKED N200 not a T-mobile one so I think the MSM tool doesn't apply
EDIT 2: I got it booted into LineageOS but now Wifi won't turn on, oh what a night of drama!!!
EDIT 3: I fixed that now too, I'm all set! Thank you!!!
