Can't flash any Rom - "assert failed: oppo.very_trustzone ERROR 7" - OnePlus X Q&A, Help & Troubleshooting

I'm currently on CM 13.0-20160809-NIGHTLY-onyx and I've tried to flash three different Roms on my phone (Two different versions of cm14 and OOS3) with TWRP. But every time I get the error message attached in the screenshot.
Now, I've seen a few people online having similar problems, but it was mostly for cm12 and the suggested fixes are not really helpful for my situation.
I've somehow lost my stock backup so I'm kinda lost right here.

In general Error 7 usually means you're using the wrong version of TWRP. I'm still using Blu_Sparks version for the new bootloader.

You need to upgrade your bootloader and TWRP.you are using very old CM and now everything is changed so upgrade your boot loader and recovery.

I already use TWRP 3.0.2-0 which is the newest version according to TWRP Manager.
How do I upgrade my bootloader?
Edit: So I found this way to do it :Link
The thing is: it says the bootloader must be unlocked, but if I type "fastboot devices" I get nothing back. "adb devices works. I'm pretty sure that my bootloader is unlocked since I have a custom rom and my device is rooted but I'm not sure if I have activated the CM recovery option in the developer settings ever since.
I really don't wanna brick my phone so I'm not sure if I should blindly follow the steps in the link above.

"fastboot devices" doesn't work unless you are in the bootloader

question about rooting

Ok so this may have been posted before but I've been searching and can't find anything.
So I got my note 2 when they released and I did the first "root" method available which I think was odin. Not really root with a custom recovery however I don't think. See the following screenshot to see what I'm currently running. Its been fine until now so I never re flashed anything or install twrp or anything.

Lately its been running slow so I want to fully root and install something along the lines of the latest Clean Rom. I had cleanrom on my Rezound and I love his roms.
Only reason I'm making this thread is because I'm not sure where to start because I don't think I'm stock yet I'm not "really" rooted.
Dont want to mess up my device.
Thanks!!

Sounds like you are rooted, but your bootloader is still locked. In order to flash ROMs on Verizon you will need to unlock the bootloader (unless you did that via Odin the first time around). From those screenshots you won't be able to tell if you have unlocked the bootloader...as far as I know the only want to check is to boot into recovery. If you see TWRP or CWM you are set...if you get the stock recovery you need to follow Adam Outler's original unlock method as you are on baseband VRALJB. To access recovery power off the device and then press volume up + power button + home button simultaneously. Whatever boots up will tell you what you need to know.
stary by reading the stickies.
Yea I believe I'm still on the stock recovery.

"This is a development device not intended for production use"

Hello,
After unrooted and re-locked (bootloader) my Nexus 9.
When i boot it, i got this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
"This is a development device not intended for production use"
After that, I have flashed the stock rom 6.0.1,so I'm 100% stock now, but I still get this message when the device boot
Is it a bug, or my seller sold me a tablet supposed to be not sold?
Do you think I can ask for a replacement? Because I would like to sell it and buy a other tablet... But with this weird message at the boot, I can't expect a lot from it...
Thanks
Strange. I am interested and want to know more.
The warning only recently appeared?

Just after re-locked my device. So i have unlocked it again to flash the last 6.0.1 stock rom, locked the bootloader, and the red message is still here. But I have seen that, if I unclock the bootloader, the message disappears, and if I lock it, the message appear... Strange.
One other thing, (with bootloader locked), I have an ota update, 7,7mb, but when I update, it fail each time
So if I send it to HTC, I think they will change it with a new one, because even with a factory reset, flash stock rom, I don't know what more they can do.
And I have light bleed on the screen, so i really hope they will give me a new one!
That's strange. I don't know whether that red message appears even if you lock the bootloader with everything being stock, but you may try this method: http://forum.xda-developers.com/nexus-6/general/guide-safely-lock-bootloader-android-5-1-t3067302
Edit: If OTA update fails, your device may not be completely stock. Try troubleshooting by consulting the recovery log, or use the "flash-all.bat" to flash stock ROM again.

Ok thanks for your help
I have send an email to HTC to ask for a replacement. I have seen that some people who got the same issue, (even without root or unlock bootloader) got a replacement :fingers-crossed: . And I have ugly light bleed on the screen, so I really hope I will got a replacement too
If the OTA fails then you aren't full stock..
DITTO to downloading the google stock image and flashing using the included flash-all.bat.

Fastboot tethered recovery error on T4 (Nokia N1)

Hey,
I recently got a cheap, slightly used chinese version Nokia N1. But because without the Google Services its pretty much useless to me, I want to root it and install a custom ROM.
I followed 2 tutorials:
https://forum.xda-developers.com/nokia-n1/help/nokia-n1-root-t3125771
and
https://forum.xda-developers.com/nokia-n1/general/play-store-howto-t3118965
But I always get stuck on the part with the Recovery Launcher.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
To give some background, here are the steps I did:
Because fastboot and the launcher won't see my device if its in MTP or PTP, I disabled both. That seems to work fine.
I "unlocked" oem in the developer settings and also allowed USB debugging.
I started the Recovery Launcher with admin privileges and used option T4.
It boots into recovery mode, but I just get errors all over the place bacause the device is still locked. So i just typed "fastboot oem unlock". Then T4 again.
Thats where this error occurs. From what I read, this should put me into a CWM recovery session. But it doesn't. It just stays in the fastboot mode window.
I'm pretty new to this android modding thing, so don't expect to much knowledge from me.
with much thanks
~David

The thing is, there are no other solutions out there I really know about. I searched google up and down and got no real result.
I think my problem is that my android version isn't 5.0.x, like almost every english tutorial suggests. It is 5.1.1.
oh God... my fault sorry

I think you haven't installed correct fastboot drivers.
This "bug" is known at some MTK-devices. There are some solutions for a few devices, by using patched boot.img, but none for this. Did you find a solution yet?

Have you restored the full stock firmware? If not then do that first using: https://pixelrepair.withgoogle.com/carrier_selection

I don't recommend using the Pixel Repair Tool unless absolutely necessary.
If you are trying to return your device to absolute stock, I recommend using the Android Flash Tool. You can choose which factory build to flash, whether to wipe the device, and whether to relock the bootloader.

It is likely that you rooted your phone at one point, or perhaps flashed an alternative operating system which does not support verified boot.
Traditionally but not in all cases, re-locking your bootloader requires you to be unequivocally 100% stock. If you plan on being on stock and you are not (which I am assuming), you can either follow the # Flashing Instructions steps on the Nexus/Pixel Factory Images page. If you find that a bit tedious, there is always the flash-all.sh/flash-all.bat which will do this all for you.
After this, your device will be set straight back to factory, and you can follow the steps to re-lock your bootloader.

This is why I like to recommend the Android Flash Tool - simply from a perspective of ease of use, and the fact it's practically impossible to get wrong; additionally, the user can elect to lock the bootloader during the process when choosing the flash options. This removes the need to do anything else manually; the tool takes care of the entire process.
It's also very useful for updates.
