So I already had a rooted (and I'm pretty sure unlocked bootlader) version of the stock Asus and wanted to put CM13 nightly on there. Everything was going smooth until I got to the stage where I have to load into TWRP and I got the error screen with the little dead alien and the red symbol.
Now I can't enter normal boot, but entering recovery mode seems to work. I tried the option to side load a package from ADB on that screen but nothing worked (.zip files extracted, but I got an error on the phone).
As you can tell, I'm really new to this so any help would be greatly appreciated. I tried looking around, but it seems the more common issue is people not being able to enter recovery mode or something similar.
Thanks
Looks like your doing it wrong. Being rooted does not necessarily mean that your bootloader is unlocked.
By the looks of it your in recovery mode with the dead robot with the "error" message. That is normal. To reboot back into system you either have to press (I don't remember) power button and volume up or down button. Then you should see some options with reboot to system. Or if that does not work you can hold the power button till it turns off.
Then you get back into Android, download the official bootloader unlock tool from ASUS and install it on your device. NOTE: If you updated to MM then this will not work and this will void your warranty.
Run the tool and press unlock and it should reboot into fastboot where it should begin the unlocking process. I believe it should automatically reboot and you should see that the Asus logo is now black instead of white. If not, repeat the process.
You can now proceed to flash twrp recovery. Boot into fastboot/bootloader mode either with "adb reboot bootloader" or hold a specific set of buttons while off to go directly into fastboot.
On the computer, connect your device and type in "fastboot flash recovery (path to twrp IMG without brackets)"
When done you should be able to reboot into twrp recovery where you can flash the cm13 zip.
Hope this helped.
Unlock bootloader
Download and unzip this archive or this archive (if you model is BTV-W09)
In command prompt:
Code:
adb reboot-bootloader
fastboot flash recovery twrp.img
fastboot reboot
Update 21/12 fot US version change twrp.img
This twrp works correctly
Rename it's to twrp.img and replace in unzipped folder
Or use this code
Code:
adb reboot-bootloader
fastboot flash recovery twrp-m3-us-greatslon.img
fastboot reboot
All new version (And for EMUI5 too) this a lot of partitions for backup/restore and images can be download here

I used the SRK Tool to get root.

Hi @Flavio,
With the unlock-code I could unlock the bootloader.
On every start of the tablet I get now a warning that my device is untrusted, after some seconds it booted up into the normal "Desktop" view.
After I've activated again the USB-Debugging option I send it via "adb reboot bootloader" into the fastboot-mode and now the FRP-status shows "unlocked".
So, I've flashed the downloaded "twrp.img" to the recovery partition and reboot the tablet.
There is no difference to see, I get the untrust-note and then it is booting into the desktop view.
BUT how can I get into the twrp-mode? Normally when I boot up with "Volume-up"+"Power" but here it started into the Huawei EMUI Recovery console, not the TWRP surface. So I've flashed the twrp.img again but no change. And when I boot directly into the recovery "adb reboot recovery" I get the untrust-hint and the note that the system is booting now, but nothing is happen. Whit a cold-reset it shows the same screen. First when I go into the Huawei Recovery mode and press only "Reboot" it is booting up again as normal as before into the desktop mode.
My 2nd question is: you say you have used the SRK Tool to root your device. But under the link I can find a toot for the Huawei Mate 8 ? You mean I can download and use this tool for the Huawei Mediapad M3 too? ...after I could install TWRP?
Thanks for you help.
Greets,
Scrab

The tool for huawei devices version 2.0 works fine (pont 4 (root), use another huawei device for routing)

Thanks ein777er for this hint.
But before I can root my device I have to install TWRP. Here is currently my stop-point due to that fastboot tells that the twrp.img was installed without issues but when I boot into the recovery the tablet stops the boot on the "untrust"-screen and first when I go into the eRecovery-mode and reboot the tablet I will be back on the working surface.
For the root process the SRK tool want as well to boot into twrp first and I end up in the same stop-screen.
Maybe this is caused from the installed version of EMUI?
I made no updates/upgrades and have only unpack it from the box. So I have EMUI 4.1 as system.
Beside this is there any known fix yet to "hide" the untrust screen during the boot?

try this :
https://play.google.com/store/apps/details?id=gt.recovery.reboot
or
recoverymode : press vol+ and power

i use it also out of the box

I need to turn off the tablet and then turn it on with Volume Up and Power on and hold it till TWRP starts.
//EDIT
OK last time I installed the Button combination changed. Try Vol+ and Vol- and Power. Had whole day headache till I recognized this

If your M3 USB plug (charger or computer) you can't go TWRP, only EMUI recovery.
please use Vol+ and Power when not connected USB for custom recovery
So I have my bootloader unlocked via the official huawei website method, and now I'm trying to flash twrp. I followed the instructions and attempted to flash twrp. See the attached screenshot of my command window. It seems like it finished successfully (only took 0.7 seconds) but I saw nothing happen on the tablet itself. Just the same white screen with the android logo that says FASTBOOT&RESCUE MODE. No script or anything changed. So far I've been unable to boot into TWRP.
I have tried holding down the VOL UP + POWER combination and it takes me to the black "Your device has been unlocked and can't be trusted." screen with the text "Your device is booting now..." at the bottom and the tablet will just stay frozen there. Then if I hold the power button for a few seconds it will take me to a similar black screen but with three options. If I do option (1) which is to hold the VOL UP button for 3 seconds it will take me to the EMUI recovery not TWRP.
Hopefully someone can help out here.
I'm stuck on the same step as you. Greatslons version of twrp doesn't seem to work on the US versions. Just freezes upon boot. Anyone have any idea why that would be?
Fyi, my working twrp flash to my non-US M3 was also very fast. So fast that I thought it didn't really do anything. But it worked.
Did you guys do the OEM unlock step? I wonder if there is some kind of region locking between the hardware and the bootloader.
I did the OEM unlock step. I also tried flashing it to recovery and recovery2, both of which didn't work. Sucks cause we can't root without twrp, yet we have our bootloaders unlocked.

Exact same issue here I got the unlock code and unlocked the bootloader, no issues there. Next I flashed twrp and got the exact same result as you. There doesn't seem to be any way to get in to twrp at all... I even tried "adb reboot recovery" but it just goes in to the "Your device has been unlocked.. " screen and then says "Your device is booting now...", then gets hung on that screen. How do we get past this? Thanks in advance for any help.
I bought this device thinking I could root it
I'm in the USA and I bought the device from Amazon: https://www.amazon.com/gp/product/B01LB08BH6/
I installed this rom: (https://forum.xda-developers.com/g4/development/h815-nougat-stock-t3659860) the correct way through TWRP and having an unlocked bootloader and then the rom worked well, but then i thought i still had the TWRP as a recovery so i tried to enter the recovery mode by pressing power button+lower volume button. afterwards i clicked twice yes. so the phone rebooted and the rom didn't work anymore. So tried to find a solution by searching XDA forums and the internet. Since my previous version was MM i found LGUP which could restore the phone to its previous ROM. however i am now having issues with LG UP. i tried several methods:
the 1st one was: from https://forum.xda-developers.com/g4/...mm-lp-t3249803 with the H81520D_00_0115.kdz file and the DLL files which came with the software itself. This always led me to 25% after which LG UP would crash and give a "error code = 0x2000 invalid command response at system". then i tried a different DLL from: https://forum.xda-developers.com/g4/...-file-t3586220 #6 which led me to have the error at 11%.
the 2nd one was: from https://forum.xda-developers.com/g4/...-h815-t3673777 #6-#11 so tried this method with these DLL files and by reinstalling LG UP and the driver, also by using the H81520p_00_0314.kdz file. but now i have the issue that LGUP gets stuck at 4% "USB connection established" and will automatically close the program and windows will show me that "LGUP has stopped working".
the 3rd one was: using LG bridge and hoping it will reset the phone. but nothing it just says that the phone has no software issues and that i have the latest software which is H81529a.
Lastly i tried to get flash twrp-3.1.1-1-g4.img through fastboot and was able to flash the recovery by using "fastboot flash recovery twrp-3.1.1-1-g4.img", however i was not able to get into the recovery because when i typed "fastboot boot twrp-3.1.1-1-g4.img" i would get an error (can be seen in the picture). so i tried to enter the recovery manually by pressing power button+lower volume button, and releasing the power button for 1 second and the pressing the powerbutton again, afterwards i clicked twice yes in the white screen, but this got me to download mode and not into TWRP (can be seen here: https://www.youtube.com/watch?v=xai6_8T8BgI)
I am now stuck and don't know what to do, and was hoping you guys could help me? I am using a PC with WIN 10 and i can boot into Fastboot mode and Download mode

Suggest you post your issue re: TWRP to steadfasterX's thread: [RECOVERY][h815/h811][OFFICIAL][MM][LL] TWRP 3 touch recovery [2017-06-21]
https://forum.xda-developers.com/g4/development/recovery-twrp-3-touch-recovery-t3442424
after reading through the OP thoroughly and seeing if any of the member's posts match your issue.
steadfasterX has proven very helpful to numerous members with issues.
LG refurb updated the ROM to 20x, and (supposedly) replaced MB & RF.
Now I can't get into bootloader, with either ADB or power/vol down combo. Bootloops instead and takes 15 mins to become a working phone again.
I've factory reset 2x today.
Perhaps factory reset and don't restore from Google?
Perhaps 20x is corrupt?
I have no idea what to do next other than deal with the apparent idiots at LG Texas. This is the 2nd "refurb" in a month and 3rd since I've had the G4.
HTC M7 is saving my sanity as backup.
finally got out of bootloop. OEM unlock was the issue in Developer options.
But now having problem getting it to boot into twrp.
fastboot flash recovery twrp.img - went ok, as per past experience.
but - fastboot boot twrp.img - is a no go.
I get this back - cannot load 'twrp.img': No such file or directory.
Can't power down with power button held for 10secs.
Only fastboot reboot works.
What happens if you try to boot into recovery with the key combo (power and vol down until lg logo appears, then release power briefly whilst still holding vol down and then press power again whilst still holding vol down - should bring you to "factory reset page" but once factory reset is confirmed should go to TWRP)
nope, goes to factory reset. tried that twice.
Ok so even after you have flashed twrp, when you enter that factory reset page and click yes twice, it actually factory resets it (that screen is there for everyone but it normally goes to twrp afterwards). Did you boot into your phones OS inbetween flashing twrp and booting to it? LG software replaces twrp with stock recovery if you don't patch the os.
The way to permanently install twrp is:
1) reboot to bootloader and perform "fastboot flash recovery twrp.img"
2) fastboot reboot
3) AS SOON AS IT REBOOTS (<-- that is important) - use key combo and click yes twice - do NOT let it boot back into the main android system inbetween, or you will need to start again
k, I'll give that a go tonite after work. Don't recall the issue with the earlier OS, 20v (before "refurb"), but I'll do oit.
What model of phone is it?
In terms of flashing twrp, that has always been the process (I have a G4 on v20g firmware and it took me a while to work out why twrp kept being wiped)
it's a G40 w/20x. Never had this issue before 20x.
still actually having an issue on reboot. Takes about 7 mins now as it optimizes 1 unknown app.
used this method from fastboot:
fastboot boot twrp.img and pointed (d&d) to twrp on my drive.
then installed twrp from memory as described on twrp page/Fastboot Installation Method.
Ding Ding Ding!
thanks.
Hi everyone,
I'm following this guide
https://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003
but unlikely I can't installing the TWRP. My phone is unlocked, I flashed the twrp but I cannot restart it in twrp mode. I don't understand why. I'm blocked at point 2 - vi. Actually, if I write "fastboot boot lgg4-twrp.img" and hit enter, I receive an error. If I write "fastboot flash recovery twrp.img", it's everything ok. but I'm blocked here. I saw someone say "keep pressed volume up and power button for about 30 sec" but nothing happens. What should I do?
