1. What phone model? What version of firmware 5.0.2 or 6.0.1?

Yes, same this with me. 6.0. I tried reset, but reset is not working. So I unlocked device , installed twrp, but twrp sometimes starts and only for few seconds. Mostly phone is either stuck in logo, or just shuts down after boot vibration. No luck in recovery. My phone crashed suddenly and got into this situation.

http://www.htcdev.com/bootloader
You have to register.
For Windows: Install HTC drivers, HTC Sync Manager(optional), fastboot, adb.
For linux: Install android-tools
Put phone into Hboot -> Fastboot.
Connect to PC and from cmd/terminal you have to execute commands as told by HTC site.
> fastboot oem get_identifier_token
This will give you a string , copy paste from '<<Identifier Token start>>' to '<<Token End>>' , only this column, no prefix.
Paste this into website. There will be text box while following steps.
You will get a file in email attachment. It will be something like this 'Unlock_code.bin'
And also the link to further steps will be provided.
> fastboot flash unlocktoken Unlock_code.bin
You will get option on phone screen. 'Yes' 'No'. Use volume button and select Yes.
and its done.
It hardly takes a minute

Yes it happens sometimes.
Make sure the recovery step was complete. For win: The .exe cmd should exit on clicking enter or automatic, till then don't remove the phone.
Try some combinations:
- turn phone OFF from Hboot then start recovery
- if screen shows 'entering recovery' let it be , wait for reboot or shutdown
- try alternative options of 'reset' and 'recovery' both will get you to twrp
- remove sdcard then try
- check charging
- don't try if overheating, let the phone be in normal temperature.
I had similar problem, but trying combos started twrp.
The mistake I did was to wipe everything. Don't do that, try to wipe cache, the first default option provided by twrp and start phone. (no sdcard/sim)
I was able to install Tomal's Discovery ROM but after some time phone again rebooted and stuck in loop.
For any restore/flash use internal memory. SDcard failed to work for me ( i tried many different sdcards).

TWRP (greatslon mod)

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

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.

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 :

or
recoverymode : press vol+ and power

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/

ROOT Elephone S7 4gb on Windows 10x64 at last!

For those that, like me, could not get driver recognition on the latest Win 10 x64 no matter what you tried. And ,yes, using every tutorial I could find on this and two "other Forums". Odin failed to see my device (still can't) Cydia impactor allows rebooting into fastboot and D/L but doesn't connect in either alt. mode. Yes, drivers all removed and replaced in varying states (usbdeview, etc.).
But ADB/Fastboot works!
Make sure you have your adb/fastboot drivers installed universally (Check this Fabulous Forum)
Download device-specific TWRP - I used this one for the 4gb version - https://www.dropbox.com/s/b7u3k1mgpppxlyx/recovery.img?dl=0
L.Shift-R. click in the folder you downloaded to (Open Command Window Here) - "adb devices" (to make sure device registers) then - "adb reboot bootloader" gets you into fastboot. - "fastoot boot {your-recovery-name}.img"
I got a fully functional TOUCH CAPABLE TWRP. Which I proceeded to load this - https://www.dropbox.com/s/j1owqv7mjkdpo75/UPDATE-SuperSU-v2.46.zip?dl=0 - and, VOILA! ROOT!!

I had similar issues with my laptop and drivers. Used a friend laptop in the end to "see" the phone and install twrp.

When I try to boot the recovery.img with fastboot it says that my OEM is locked. I check OEM unlock in developer options, then I do: adb reboot bootloader, then fastboot oem unlock. A warning appears saying to press VOLUME UP button to continue, voiding the warranty or VOLUME DOWN to go back. I try to press VOLUME UP and nothing happens... how did you do it?

Hi there, I have the same issue. No success

I found a way, instead of volume up, use the home button this worked for me.. however after I unlocked the OEM and flashed TWRP the phone didn't want to boot anymore. It was stuck on Elephone logo with warning: "Orange State: The phone has been unlocked and can't be trusted. Your device will boot in 5s", however it didn't boot and stayed like that for almost an hour. Had to flash back the stock firmware to boot. Tried 1 more time the procedure to root but again the same. Maybe I do something wrong?

stock fw flash back
Hi, please can you help me with how you flashed back the stock firmware?
I get an error message with twrp : invalid zip file format.
Thank you in advance!

I read somewhere the is a zip inside the update.zip & is that one that is flash able with twrp.
Have a look

During the main time I managed to flash the 0218 stock rom.
I still got the orange message but the phone finally boot. Then I just called the twrp recovery img via atb. I did nothing only touch the reboot in the twrp screen and since then "Orange status...." again.
May be the twrp recovery img is not the right one...

Bad command "fastoot boot {your-recovery-name}.img"
after OEM alow (informacion phone/compilacion number touch fast 9 times/access/alow oem)
fastboot oem unlock
"fastboot boot {your-recovery-name}.img" for me is fastboot boot recovery.img and all OK
bat still not working (phone not thrust unlocked bootloader cleaning data in 5..4..3..2..1.. and rebot)

How to wipe android partitons while NO access to Fastboot? PLZ help

Hi,
I have a unique problem. I cant go into fastboot. Yes, fastboot on my OPT is not a opltion.
I cant instal TWRP. I can't wipe the OS to flash a new one.
My question is this:
Is there a way to wipe the partitions on a android phone via windows or something?
This problem is created by me. Somehow I flash OOS over CM (??)
So when my phone boots (bootloader is unlocked) I will see 2 boot sequences wich prevents me from accesing the fastboot menu.
The solution I see is this: Enter TWRP --> Wipe all but USB-OTG ...
Anyway, I hope there is a android Einstein here because I'm at a loss..
Feel free to ask any questions and pls help me!

If you are getting two boot screens, please confirm if this is what you see in your first boot screen:
some text which goes like "Your device cannot be trusted etc etc. fastboot oem lock something something"
If yes, press the volume buttons at this screen, which will take you to an "Options menu"
This will have options to power off, restart, recovery, fastboot, back to previous page.
use volume down buttons to move selection to fastboot and press power button to select fastboot.
This will take you to bootloader.
Alternatively:
Is the device getting identified by your computer when connected?
If yes, and if you have adb tools installed, try this command, after connecting to computer and selecting usb configuration as transfer files
adb devices
The result of this should show your device
then type:
adb reboot bootloader
This should take you to your bootloader screen.

Thank you for your replay.
I have done all of this and i do understand how this works.
I have adb drivers installed, my computer does reconizes my phone and everything works even the reboot to bootloader via CMD. (adb devices, it shows, etc)
When my phone then tries to access the bootloader, it will show those messeges " this devices cant be trusted etc etc." afther 5 seconds again I see the the android logo (with a few lines of static on the bottom) (( that clearly is not right )) but it will show me again the same message " this devices cant be trusted etc etc" ... then it will just show me the battery icon and power precentage (this if I choose to boot to bootloader) or else it starts normally..
Clearly the flashing of CM failed. And with a sideload to install OxygenOS I can use it.. But it does prevents me from accessing the fastboot mode..
So Is there an alternative way to install TWRP without using the fastboot mode? Or is there an other way i can try to wipe the partitions inc. the os?
From there I know what to do.

So if you cannot boot to bootloader by pressing power and volume down at startup, you can try to enter recovery by pressing power and volume up. Then if it says no command hold the power button and press volume up one time. Now you should enter recovery. then from here you can try to enter bootloader.
Then flash your image via Miflash

the point it is, how can i flash via MiFlash, even they request the bootloader unlocked, when I begin the flash, they show the error, that nothing can do because the bootloader are locked, the program can't do nothing, i open device, initializing the phone on EDL mode, but, when flash system is done, from edl mode, they stuck on boot loop.

I can enter the fastboot mode, I can enter the recovery mode, but the device does not respond to anything and gets bootloop

Ok, you said you can enter edl mode even the bootloader is locked right?
How did you do this? You said you opened device, did you short the two test points. I have a similar Problem.

Seems like there are other Posts with different problems at the beginning which are now facing the same problem as we do, after some flashing:

please help as fast as possible.

EASY FIX for this problem!...go again into fastboot mode....POWER button + Volume DOWN - in the command prompt on the PC type: fastboot oem unlock
system erases all the data and starts again had the same problem! i installed magisk to enable camera2pi, so today i got the mi mix 3 and i thought hmm lets lock the bootloader mi a2 lite and erase all the data so i can pass it further to my mum and she´ll get fresh updates! unfortunately, when i did fastboot oem lock, it said "system .blablabla..destroyed" ! Now everything workds fine again!

You can also flash stock rom with Miflash tool and choose the option at the right bottom to "clean all and lock" after flashing you've got stock rom and relocked bootloader
