[Q] Question about Diag mode - Sprint HTC One (M7)

After many tries I finally managed to get my MSL and enter in the diag mode with the code ##DIAG#.
One thing that I saw is that if I S-OFF the device it can't enter the diag mode. It shows me the menu where I select ON or OFF and if I select ON it just shows me a message saying "Please wait . . . . " and that's all.
Is the diag mode only for S-ON ?

Cant unlock the bootloader

I have 20a firmware and that should be unlockable. Ive tried different solutions but none of them works.
Ive tried with script but it says permission denied.
Ive tried with the all in one tool but when it reboots it shows an error message at the top of the screen "ERROR : boot image signature".
Its just my fault or i just cant unlock my phone with anything?
If i try from terminal the adb reboot oem-unlock line reboots my phone but it also gives unlock permission denied error message.
So I cant unlock this... any ideas?

I did it by doing this you can give it a try!! to unlock bootloader ( so you can flash roms with kernels) go to this thread, http://forum.xda-developers.com/show....php?t=2224020
and download the BL_unlock_new .rar file when its download copy it to your desktop on pc and then extract it to desktop on pc . now make sure your phone is not connected to your computer go to phone settings,then go to development options, and then select usb debugging on. once debugging is on now connect your phone to pc wait for it to connect you can keep your phone on charging mode. now open the BL_unlocking_new extracted folder on desktop on pc and double click on the BL_unlock file a box should open up on your desktop asking you to tap a key to continue so press a key now your phone should reboot and some white writing will appear on screen .on your desktop the bottom line should say please... now tap a key on computer it should say press any key to continue < waiting for device> now disconnect phone from computer look on phone screen it should say now ready! now hold power button for 10 secs and let phone reboot. to test if bootloader is unlocked on phone go to dail pad and dail this 3845#*880# you should get the hidden menu on your screen scroll down to bootloader unlock check and select then select bootloader unlock check and hopefully it should say unlock...
I had the same problem as you. Tried everything, but the only one that works is this one:
http://forum.xda-developers.com/showthread.php?t=2245415 it's also the simplest way.
Goodluck!
Sent from my LG-P880 using xda app-developers app
Thanks guys i figured out how to unlock on my own... but really, thanks for the help

Can you boot into the bootloader?

go to settings > about > software information > more : hit Build number 7 times till you get message (you are now developer)
go back to the settings screen, scroll down, you will found new option called (Developer options)
hit it, new message will appear , hit (OK)
now in the (upper right ) hit the (off) icon to change to (on)
find (USB debugging) and mark it
now adb will detect your phone
about the UNLOCK_CODE.bin, re-send your phone "token code" to the HTCDev.com to receive the UNLOCK_CODE.bin again and try again

The OEM Unlock option does not appear on my phone. Mobile is in "normal" mode, I have more than 7 days of uptime, the option simply does not appear. I've tried all the tricks I've seen on the internet. SM-A305GT. Would anyone have any solution?

V40 on startup: "Your device has failed a routine safety check and will not boot."

I was following this guide to try to flash a US firmware on my bootloader-unlocked Sprint V40: https://forum.xda-developers.com/lg-v40/how-to/guide-make-lg-v40-compatible-lgup-t3953120
After issuing the command "fastboot.exe set_active a" then powering off and trying to enter download mode, I get "Your device has failed a routine safety check and will not boot."
It briefly goes into download mode after that (for just a few seconds). Then I get a green screen with black text that says "LGE Crash Handler : FIQ : NOC Error!" and has a whole lot of other diagnostic info.
my one says all slots are unbootable

You have to restore your software again and re-root
Hold Volume+ and plug the phone to your PC to get it into download mode. Use LGUP to reflash the firmware.

dm-verity corruption Oppo Reno 3

So after unlocking my Reno 3 bootloader with Unofficial way (with mtkclient ) i have this message when phone is booting "dm-verity corruption
Your device is unlocked and can't be trusted to continue press the power button "
And the phone is working fine and bootloader status in " developer option ==> oem unlock " is UNLOCKED
the problem here is I can't access fastboot mode or recovery mode but i can enter EDL or BROM mode.
So the question is there is anyway to access fastboot?
Ps : i tried adb command
" Adb reboot bootloader & adb reboot fastboot "
But the phone reboots to normal
2- When i press volume - & power the phone keeps vibrating like he is rebooting again and again
NOTE that i remove my hand off the power button after the first vibration.
Same problem
