How to install TWRP into the LG P500H from Koodo?

I have a Koodo LG P500H. I am having a very hard time installing TWRP.
Firstly Play store doesn't work. It has this old thing called "Market" that has some apps, but not all. Market eventually gets updated to Playstore, but I can't even find TWRP manager. There was another app in the Playstore that I tried called ROM Manager. It said it installed TWRP for me. I restarted the phone, and nothing happened.
Restarting and Holding power/volume down/home will show a picture that seems to be some sort of recovery mode. But it only run for 1-2 seconds before the phone restarts itself. Nothing happens.
I tried to use ADB. But after rebooting the device it just restarted without ever going into recovery mode. So the flash command just get stuck at "Waiting for Device." Does this phone even have a recovery mode?
This phone doesn't support Odin.
I am used to using TWRP. Without it I cannot flash the phone into new OS.
And every single time I fail, the whole phone seems to have reformatted. So I have to enter in my wifi password and gmail again. All of that typing on a very small keyboard takes a lot of time. I had spent hours on this phone without getting TWRP working.
Please help.

The problem is when I reboot into fastboot (adb reboot bootloader), the phone will go into "phone off battery charging mode". It never actually goes into the bootloader.

Ok I did the following and it seems fastboot and TWRP works now. Be sure to enable USB Debugging on your P500.
1) Fastboot tutorial (I did everything here. I hit "ok" on the LGMDP 1.5 tool as needed. Do not wait till the countdown timer goes to zero.)
http://forum.xda-developers.com/showpost.php?p=15122833&postcount=100)?
FastBoot Tutorial
1. Please download this (or from here) file and unzip it in to any folder.
2. Start LGMDP 1.5 tool with the phone connected (you need to have USB drivers installed) and click on Select Port
3. A separate window should appear like the one below
Just click connect
4. Another window will take shape (LGE Mobile security) with lots of options (links)
Click on the first upper right Browse and select the folder in with you have unzipped the files. You will get some errors that some image, table or headers are missing. Just click OK and in the end everything that should remain selected is Partition Table, APPSBL Image Header and APPSBL Image.
Now just close the window (click on x)
5. Now you are back on the main window and here you'll have to click on Download
6. You are almost done and from now on everything should go on automatically.
NV Backup
Autorestart in Emergency\Download mode and upgrade the files (you selected on step 4)
NV Restore (the last step) Do not disconnect the USB cable until the restore is done
Wait for the phone to restart in normal mode (your current rom).
That should be everything you need to do to get fastboot enabled.

2) Install PdaNet+ (This was the only thing I did in this tutorial. It fixed the usb driver and the fastboot can then communicate with my PC.)
http://forum.xda-developers.com/showthread.php?t=1350733
http://pdanet.co/a/
(Note: On top of Partition Table, APPSBL Image Header and APPSBL Image in step 4, I also selected the TWRP image file as my RECOVERY image. Not sure if this make a difference. )
(Note 2: I think you can also get the LG drivers here.)
3) Restart, hold down power + home to boot to the fastboot. Or in ADB type adb reboot bootloader.
4) Open ADB (while phone is still in fastboot mode) and type fastboot flash recovery twrp.img (after downloading the TWRP image, renaming it and moving it to my ADB root folder. I am using TWRP 2.8.0.1 here.)
5) Type fastboot reboot
6) After the phone restarts, type adb reboot recovery. TWRP runs for me. Power+Home+Volume Down (3 button combo) also works now. (Previously this would reset the phone.)

Hey Man, im glad it worked. I could use your help.
I bricked my phone and need the restore file, Do you think you could make a backup from TWRP and upload it?
I would be super grateful.
Thank you.
Here is a zip with CM11, twrp 3.0.2.0 and Gapps for CM11.
Its the best rom I found.

Hi. What is your "brick" like? Does your TWRP still run? If yes you can just copy a custom OS into your Microsd card and install it from your Microsd.
You can also use ADB push to move files from your PC to the phone.

Sent from my MT2L03 using XDA-Developers mobile app
If you TWRP doesn't run, you need to install that first. Do steps 3 and 4 in the above post to boot into bootloader and install TWRP.
3) Restart, hold down power + home to boot to the fastboot. Or in ADB type adb reboot bootloader.
4) Open ADB (while phone is still in fastboot mode) and type fastboot flash recovery twrp.img (after downloading the TWRP image, renaming it and moving it to my ADB root folder. I am using TWRP 2.8.0.1 here.)

[Guide] BQ Aquaris M10 (freezerhd) twrp & root

Hi,
as I did not find an English guide for rooting a BQ Aquaris M10 tablet and had some problems when trying to root my tablet, I want to post an guide how to root this tablet.
First of all:
- This guide is just from my experience and is not thoroughly tested. It's on your own if you risk bricking your device.
- If you get stuck in the process, in nearly all cases you can revert to stock with the MTK flash tool (can be found on mibqyyo.com) and the images provided by BQ on their website.
- I could not unlock the bootloader with the 1.X-Images (Lollipop), as the VolumeUp-Button didn't work in fastboot-mode and you need this button to confirm the unlock.
- Booting into recovery from start with VolumeUp and Power-Button. This doesn't work with the 1.X-images, too.
- This guide is not intended for users without experience in unlocking/rooting a device. If you don't know how to use adb, fastboot, recovery and things like that, don't try it!
- You will loose all your data during this process!!
Guide:
Modify boot.img, flash new firmware
SuperSU in systemless mode doesn't work on stock image, as the SuperSU installer can't extract boot.img. You have to repack boot.img.
I tried a SuperSU installer without systemless-mode, but device didn't even boot anymore afterwards.
This guide is derived from a Spanish tutorial on the HTCmania-forum ("Root M10 HD Marshmallow") by yquepongo. Thanks to him!
Get a firmware for your device from the BQ-website (should be Marshmallow, see above) and unzip it to a directory.
Extract the boot-verified.img in the firmware directory with a bootimg-extractor. There are various tools available.
I used bootimg.exe, because this was explained in the mentioned thread and I even used it with wine on Linux and it went well.
Search for cpiolist.txt in your extracted boot-verified.img and delete the first two lines:
mode:mtk
mtk_header_name:ROOTFS
Repack boot-verified.img and put it back in the firmware directory.
Flash the modified firmware with the MTK flash tool according to the tutorial on .mibqyyo.com (Title "Hard Reset for the smartphone range Aquaris and Aquaris E"). In short: Disconnect device, start Tool, load scatter file from firmware directory, choose firmware upgrade, start download, connect the device in power off state, download will start automatically.
This will delete all your data and put the device back to factory rom (hard reset)!!!
If you don't want to flash the complete firmware, you can flash only the boot-verified.img with "Download only" in the flash tool. I didn't try this and don't know if this is working.
Start your device, don't activate any security settings to prevent encryption of data partition.
Unlock bootloader, flash TWRP, install SuperSU
Enable developer settings on device and activate "OEM unlock" in developer settings.
Reboot into fastboot (adb reboot bootloader) and unlock bootloader (fastboot oem-unlock).
This will delete all your data!!! Reboot your system afterwards to make sure everything is still ok.
Do not activate any security settings and make sure your data partition is not encrypted!
The existing TWRP-image can't handle an encrypted data partition, you will end in a boot loop and have to start the whole process again!
Double check, your data partition isn't encrypted. (Settings - Security)
Reboot into fastboot (adb reboot bootloader) and flash the TWRP-image from the TWRP-site (fastboot flash recovery twrpxxx.img)
After reboot TWRP should start.
If you have checked that everything is ok (I would recommend a reboot into normal mode), you can install SuperSU with the standard-installer-zip in TWRP.
If you didn't modify your boot.img, the installer will give a warning that it cannot extract boot.img and you will not find any SuperSU on your system.
If you get stuck in bootloop afterwards you can start anew and try it with another image flashed with MTK flash tool. (Firmware 2.2.0 from December 2016 for freezerhd worked in my case)
Maybe some steps could be shortened, but I haven't tried it.

Sorry, but I can't help you there, as the M8 seems to be too different to the M10: I didn't have to unlock the boot.img, it was easy to unpack.

hi zrfl,

he will implement the bq specials in his tools.

this is the only way to root this device !!
thanks a lot ...

Thanks for this tutorial.
I've followed all the step, I'm able to flash the new recovery from the TWRP website but then I do a
Code:
fastboot reboot-bootloader
but the device reboot normally, just with a warning message during boot saying something like "This device is unlock and can't be trusted, it will boot in 5 seconds".
So I'm unable to access TWRP recovery, I guess when the device reboot it override the recovery partition because if I do a
Code:
adb reboot recovery
I end up in the Android recovery not TWRP.
Any idea ?
Thanks

Sorry, I have done this a long time ago and don't know what could be wrong:
You have the correct message, so unlock was successfull
You try to reboot in fastboot, so you flashed TWRP correctly in fastboot-mode
And I don't have the device at hand to try it myself. But I do have a few suggestions, what you could try:
Don't try to shorten procedure with unlock and flashing of TWRP at once. I'm not sure, but I think I had problems when I tried this. So do a normal reboot after unlock, before booting again into fastboot and flashing TWRP. (Now you have done this already )
I don't remember the proper boot command after flashing of TWRP. But
Code:
fastboot reboot-bootloader
doesn't make sense: You are already in bootloader.
Is there a boot-option in the bootloader where you could choose recovery?
Otherwise better power off and use the key-combination for booting into recovery: VolumeUp+Power.
I think, you have to repeat the procedure, as recovery seems to be overwritten: Boot into fastboot, flash TWRP, reboot into recovery. And avoid normal booting before first boot into TWRP!
Did you use the newest TWRP 3.1.0 from March 8th? I haven't tried this yet, so there could be the problem. You could try the previous one: 3.0.2 from last year.

Thanks, I succeed with the combo key (power + vol up) directly after the reboot process

Perfect it's working great now !

I did exactly what you wrote but SuperSU won't install because it cannot extract the ramdisk...

Hi @zrfl
Thanks for your posting!
I did as you suggested and successfully unlocked bootloader and installed TWRP 3.1.1. Your hint to modify the boot-verified was extremely helpful, as I wouldn't be able to unlock the bootloader otherwise.
However, I did not manage to install super su. And boy, I tried many different versions od regular/system/systemless supersu, each flashed according to the respective how-to.
I ended up either in a bootloop, or get stuck on the Android logo at boot.
Flashing goes well until this step:
"Decompressing ramdisk
--- Failure, aborting"
I checked ramdisk compression of boot with Carliv image Kitchen and it tells me that it already is set to "gz" and not another compression TWRP can't handle.
Please help me on how to flash SuperSu.
Thanks and best
Tom

There is something wrong: TWRP does not need a modified boot.img.
Maybe newer ROM-versions are different.

Solution for geting root on BQ M10 FHD on stock rom 2.6.2: Start with a fresh system and install magisk beta (not stable), reboot and root is granted!
tanks a lot to @scafroglia93!

Are there any Custom ROM's
For this Tablet like CM/LineageOS AOSP etc?
Googling reveals nothing and Considering all the kernel mods like hardcore and Ubuntu touch I find it hard to believe that nobody has built one of the later.

I've been searching for custom ROMs too. Apparently, there are none available at present. However, I'd highly appreciate lineage rom.

Z3 Won't start or enter recovery

Guys,
I need help. I'm struggling for the last 3 days trying to revive my phone with no sucess. :crying::crying::crying:
I managed to put a custom rom sucessfully, but i had to make a restore on recovery mode.
During the restore process some error ocurred, something like "something not mounted", i did'nt have the ROM to flash anymore. For no reason i decied do reboot the phone.
Now i can't enter recovery anymore and the phone is froze on the "Sony Xperia" on the begginig.
Since start i'm having difficulty with the Z3 driver for Windows 10. To enter recovery mode i tryed to adb reboot recover but my adb doesn't work.
It's strange..
if i type fastboot devices it's show.
if i type adb devices it's show's "no emulators/xxx found".
I need help, don't know what to do anymore.
TLDR:
- Frozen at "Sony Xperia"
- Recovery don't enter pressing Volume Down/UP
- adb devices doesnt' work.
- fastboot devices work
Thank you!

You have some choices to restor stock rom:
1) Try Xperia compagnon fron Sony ==> Software repair (not shure about the label in english version)
2) Use flashtool (google for it) and a rom (*.ftf) of your choice.
When you are back to stock, then you can install a custom rom again

Hey,
Sounds like a corrupted system, not too sure what happened with the recovery though.
Try this out:
1. You need the phone driver and the fastboot & ADB driver. You can get the Sony phone drivers from the Xperia PC Companion. You can get fastboot & adb drivers almost anywhere, just google for them or scroll a bit through xda.
2. Unlock your bootloader if you haven't done so already here.
3. boot into fastboot mode by completely powering off the phone then holding "power+volume up" and waiting until a blue LED appears in the top left.
4. Find a custom recovery, rename it to recovery.img, navigate to the folder that contains it in CMD (i.e. cd C:\Users\USERNAME\Downloads\Android) and type "Fastboot flash recovery recovery.img"
5.You should now be able to boot into recovery again. All that's left is find a ROM of your liking, push it to the phone in ADB and install it.
Hope this helps!

The Ultimate guide to flash and root Xperia L (aka, taoshan)

This thread will guide you to flash a custom recovery, Root the device, flash custom ROMs. Firstly, read the entire post and then start your work.
I am a noob. But I have a little experience of rooting and flashing. This device gave me nightmares which are less than as compared to the Xperia Sola which I bricked some years back.
My device has a problem. It does not help install twrp with the traditional ways we know like we can see in the Official TWRP website using "dd" method, the Cyanogenmod link using fastboot commands, the Flashify method, the RecoveryApp method whose apk I never found and the Recovery Installer Utility.
I came to know that either my phone don't have the recovery partition or the phone is overriding all the commands.
Using fastboot commands would give the error like in this post.
Using Flashify would tell me there's no recovery partition found. Rashr would complete the flash process but after booting to recovery, there was no TWRP, just the stock Android recovery.
If you read carefully on the twrp page of XL, there's a line which caught my attention late enough.
It means that TWRP may not work on your device unless you install other custom software as well.
Click to expand...
Click to collapse
Flashing custom kernels with flashtool is easy and they come with recovery pre-installed and lots of amazing stuff, but they won't do any good with the stock ROM. I've tried the Extended stock kernel, the Phantom Kernel and the Thunderzap 4.15.
After surfing the web and forums of other devices, I found that there is a chance I can fix things by updating/repairing software via PC Companion. But something happened and repair also failed.
I can't tell the reason why this happened. And I didn't store the logs. But with trial and error I found some workarounds.
Actual Methods start here
Rooting the device
If you only want to root your device for various reasons, then you will need nothing but a Rootkit. Check out this post about Rooting Xperia L.
But if you are planning to install custom ROMs for your device, then skip this rooting step. It won't be necessary for this condition.
Flashing custom recovery
*Try this method only if above-mentioned method fails*
1. Download TWRP 3.2.1 img. The 3.2.2 and 3.2.3 versions work perfectly but they caused the screen to flicker like hell on my device. Rename the file to 'twrp.img'
2. Download and install adb and fastboot drivers system-wide.
3. Connect your device to PC via USB cable and enabling USB-debugging mode.
4. Open Windows Powershell/Command Prompt in the twrp download directory by pressing Shift and clicking right mouse button.
5. Use fastboot command on stock ROM without root and Unlocked Bootloader. Instead of flashing twrp image to recovery, flash to boot. Use the code:
Code:
adb devices
adb reboot fastboot
Wait for device to boot into fastboot mode. A blue LED will flash when connected.​
Code:
fastboot flash boot twrp.img
fastboot reboot
After reboot, don't boot to system. Boot to recovery by pressing volume up repeatedly when pink LED glows. Stop when device vibrates and LED color changes
Flashing custom ROMs
Once the recovery is installed, everything becomes easy. you can find different custom ROMs on the device page here on XDA.
My favorite one is The resurrection Remix Nougat. It is stable enough to be your daily driver. You can head to that page and follow their instructions. But I will also provide steps here.
When in TWRP after the last step, move the downloaded zip file of the ROM and GApps you want to install to the storage of the device by simply connecting via USB.
After that, in TWRP click on Wipe->Advanced->Tick on System, Cache, Dalvik cache. Then Do swipe to begin wipe.
After wipe, go back to main menu. Tap on install, select from the list the ROM zip. then tap on Add more zips and select the GApps zip and then Swipe to start flashing.
After flashing, reboot to system. The first boot takes time. Don't panic if it won't boot.
Install TWRP to FOTAKernel
After booting to your new ROM, you can install the TWRP to your FOTAKernel.
This can be done as following:
Get the downloaded TWRP img file and push it to the device using command line. Open command prompt in the TWRP directory and type,
Code:
adb root
adb wait-for-device
adb push twrp.img /tmp/twrp.img
Now extract the TWRP image to the FOTA partition code,
Code:
adb shell dd if=/tmp/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel
Now reboot to recovery
Code:
adb reboot recovery
Note that custom ROMs often come with Root access inbuilt. If your ROM happened to be not, and your ROM is based on Lollipop or later version of Android, you can root with Magisk. Just read carefully before proceeding.
Comments are welcome!

Hi.
I'm following this thread and I'm stuck on the fifth step "... flash to boot. Use the code:
adb devices​adb reboot fastboot "​
I think my Sony Xperia L C2105 does not have the fastboot mode.
Here's what I did:
Drivers for Xpleria L are installed.
The bootloader is unlocked (I think!)
1 - installed 15-second ADB
2 - open Windows power shell
3 - Command: adb devices
Response is: "List of devices attached: ZH8001ADB3 device"​
4 - Command: adb reboot fastboot
Response is: long pause, phone booted but in normal mode, and light is red ...!​
5 - Command: fastboot flash boot twrp.img;
Response is: "<waiting for device>";
- phone still running in normal mode and the light is red.
- few minutes later, the phone is charging with green light present.​
I think the phone is rooted.
I used the code provided by the Sony website to unlock the bootloader.
Using the Root Checker Basic app, I get the info: "Congratulations! Root access is properly installed on this device!"
But if I type in the dialer *#*#7378423#*#*, and go to Service info > Configuration > Rooting status is "Boootloader unlock allowed" !!
Is that why it does not work?
I tried switching it off and doing Boot into Xperia L Fastboot Mode Using HARDWARE BUTTONS, but the phone is dark, with no picture, and the led turns blue.
Using the command:
PS C: \ adb> adb devices
List of devices attached
PS C: \ adb>
I've been trying to do that for a few days now and I still have not managed it, even using other advice.
Can someone tell me what to do?
Thank you in advance.

1. When in fastboot mode, you should type in cmd "fastboot devices" to check the device connectivity. If you can't, then connect using hardware keys.
2. Blue light indicates that you are in fastboot mode. If list of attached devices are blank, that means drivers are not installed (properly). Connect your phone again in fastboot mode and check your drivers page, Win+X > M (I am assuming you must be on windows). There must be a tiny yellow triangle on your device's name. Right click on it and uninstall it and remove device. Try again installing drivers from the flashtool's folder. Disable driver signature enforcement if you are having trouble going the straight way.
3. Your bootloader is still locked because if it had unlocked then the message displayed would have been, "Bootloader Unlocked: Yes" or something like that. Try flashing your stock ROM via Flashtool. Wipe cache and data while flashing. After flashing stock Rom, try unlocking bootloader again. I believe you are using Flashtool.
4. If you are rooted, then you must have any SuperSU app installed on your device. And it's all good even if you are rooted.

[UNOFFICIAL][DECRYPTION WORKS] TWRP 3.3.1 for UMIDIGI F1 [20191103]

Introduction
This is an UNOFFICIAL TWRP port for UMIDIGI F1 that works properly with encrypted /data partition in official ROM. I am aware that the UMIDIGI F1 already has TWRP built for it, but none of them seem to have decryption working properly. In fact, every single TWRP, even official ones, for any MT6771 device, seem to have non-functional decryption support. Through some digging I managed to fix decryption at least for UMIDIGI F1, so here is my version of TWRP for the device.
Known Bugs
- Screen may flash on the password-input UI. Anything else is fine though.
This TWRP has been tested with official ROM and my LineageOS 17 port (https://forum.xda-developers.com/android/development/unofficial-lineageos-17-0-umidigi-f1-t3997827) and it works fine.
This is UNTESTED on the F1 Play. ONLY TESTED on regular F1.
Why Bother
Because security matters. Using a cheap device should not mean giving up security, and more importantly, privacy.
Instructions
1. Unlock bootloader
2. Enable ADB debugging in system
3. Execute "adb reboot bootloader" while having your phone connected to PC
4. Execute "fastboot flash recovery <your_downloaded_recovery>.img"
5. Reboot phone while holding Volume Up + Power buttons
Note: The official ROM may overwrite the recovery, so you may need to re-flash the recovery if this behavior isn't prevented either by TWRP or manually.

I appreciate your sharing this. I have added "system_image emmc" to the fstab file, so I can flash and backup the system.img
This works good on my F1,
But I tried to make this decrypt work for my other phone with 6771(Bold N1), but couldn't find all same files added to recovery/root from stock firmware.

Those files are extracted from vendor.img, but it can be different on different devices, e.g. keymaster version might be different. Also you will need to patch them using `patchelf` to make them use `/sbin/linker64` instead of `/system/bin/linker64`

on other releases, no change was needed to boot on both. I would try as is first.
as long as you have working sp flash tool in case of issue.

Cause i test it without changes , it reboot to system
I think because they have different kernels

I am unable to install twrp.
When I run the "fasthboot flash recovery" command, cmd aparace "waiting for de ice" and nothing happens on my phone ...
Am I doing something wrong?

no fastboot response
for some reason (most likely pilot error, lol) the phone doesn't show when I do "fastboot devices" - even though the F1's screen shows "fastboot mode" in very tiny letters on the bottom-left.
probably something stupid I'm doing wrong, will keep trying...

You can operate from adb/fastboot folder and device can stay on fastboot mode but if drivers were not properly installed then no connection with pc.
Try installing:
- https://androidmtk.com/download-15-seconds-adb-installer
- https://androidmtk.com/download-mtk-usb-all-drivers
- https://www.androidweblog.com/download-mediatek-usb-vcom-drivers/
Start the process from device on using adb commands to always allow access to the pc. I mean:
Code:
adb devices
and then if device is detected you will see a screen warning to "always allow...." then tap on yes; this suppress future conflicts, then
Code:
adb reboot bootloader
while on fastboot follow with
Code:
fastboot devices

thanks!
adb was already working (is how I made the thing reboot to bootloader, and yes I did tell it to permanently accept the computer I'm using.
this is on linux, so the drivers shouldn't be a problem... although SMH I never put USB IDs into the udev rules. which is interesting, because regular adb already worked fine without it - I have had phones in the past that some did, some did not, require the computer to know about vendor/hardware ID.
(and I know that the adb USB IDs are usually different than the ID for fastboot, as well.)
like I said, pilot error lol. but thank you again for the reply!

I have done the following:
Enabled Developer Options
Enabled USB Debugging
Enabled OEM Unlocking
Unlocked the bootloader with:
Code:
adb reboot bootloader
fastboot flashing unlock
Rebooted and Enabled USB Debugging again.
Then after downloading your recovery
Code:
adb reboot bootloader
fastboot boot ~/Downloads/recovery.img
But nothing happened.
I rebooted and thought I would try flashing
Code:
adb reboot bootloader
fastboot flash recovery ~/Downloads/recovery.img
It just paused on the boot screen saying "Your device has been unlocked and can't be trusted".
If I reboot then try to go direct to recovery:
Code:
adb reboot recovery
I end up with the broken android screen and "No command"
What am I missing?

While in fastboot the first you should do is see if device is detected by pc with
Code:
fastboot devices
It looks like something is wrong with your path, I ever avoid path copying or moving the file/image to the adb/fastboot directory but anyway if you don´t want to do it you can copy the path from the bar where your recovery file is allocated, for example, if the file is in Downloads directory like it seems actually is, no matter what unit/drive you are in you can set an absolute value to avoid errors, look at this example: C:\Users\your_user\Downloads
If your device is detected then you can flash the recovery as you were trying to do it with
Code:
fastboot flash recovery recovery.img
and then you can reboot directly to it without need to reboot to system previously and this will prevent TWRP from being overwritten, with
Code:
fastboot boot recovery.img

hmm, so when I checked the udev rules, it already had one for MTK/mediatek - and the USB vendor is '08ed' in fastboot as well as in regular adb, so it wasn't a problem with udev/plugdev.
which I guess may mean the lunix generic android drivers for fastboot might be... "lacking" - I'll have to scrounge up a win7 laptop and try the recommended windows drivers.

I don't think it was anything to do with the path as it output the file transfer size.
I think it was a combination of the following:
I wasn't pressing the right combinations of buttons after flashing.
i.e. holding VOL UP and pressing POWER on the screen saying "Your device has been unlocked and can't be trusted".
Rebooting might (?) have been reverting the recovery.
I was originally trying this on the firmware that was shipped 2019012414 but after flashing 2019090418 with SPFlashTool I had more success.
I also able to reboot to recovery directly after flashing with fastboot with the following:
Code:
fastboot oem reboot-recovery
Whichever was the key I can now reboot to recovery from adb too.

Your twrp eliminates fingerprint authentication.
I discovered something interesting, your twrp only works on my device, no other twrp works, but when I install it, I lose my fingerprint, it doesn't work at all.
Simply put, I must choose between the fingerprint or the root.

Try to clean flash last vendor build with spflash tool. First boot need stock recovery.
You don't need custom recovery to achieve root.
Maybe give a try to SNwriter (I never needed it though and can't help here).

Both of those twrp are not sticking. I have flashed with spoken flash tool v5 1944 win and I fastboot cmd with the same results.

Thanks
Gracias for this master ?

good
