[Need Help] Locked Bootloader Cubot X11 - Android Q&A, Help & Troubleshooting

Hello!
I have a problem.
I have few phones i experiment with for making custom recoveries and custom roms and this Cubot X11 which i planned for doing a custom TWRP and custom rom for, i used the combination to get into the bootloader to select Recovery, Fastboot or Normal, but all it does is showing the Logo of Cubot aand then it goes to a blackscreen and then back to the Logo and starting the phone normally.
I tried to root it quickly with kingroot and went with ADB into Fastboot and then tried fastboot oem unlock, but when i confirm it with Volume + Button, all it does gives me an error and the console on the PC says "Unlock failed - Err:0x7000".
I heard that it is apparently a bug with Mediatek Devices, the Cubot X11 has MT6592 Chipset and i found a russian forum where there is a fixed boot.img but it got removed few years ago so i cant try that, i cant find anything for it and pages like needrom literally only has the Cubot X11 firmware so i thought i will try to work it out somehow.
Can the problem with the unlock failed be because of the bug?
I hope theres a way to fix it
Thanks in Advance!

[SOLVED] unlocking SGP312 makes it loop boot process, no kernel working

Hi all
Let me expose my problem :
I got an unlocking key from sony ; when I use it with
Code:
fastboot oem unlock 0xDEVICESKEY
, the boot process loops : I can see the sony logo, then the Xperia logo, then a few colorwaves, which in turn stalls for a second or two, and then the device reboots.
I tried to flash the device with kernels adapted to SGP312. Flashing succeeds if I unlocked just before (if I want to re-flash I have to re-unlock), but the device then doesn't boot at all.
I could never access recovery, but I read this thread saying that's normal with stock kernel. Though I couldn't access it having flashed any other kernel.
Thus I'm locked into android.
Can anyone help ? I discussed this with Mamenyaka, he suggested I posted my issue here. I tried to find a similar case in the forums but couldn't figure anything close to this.
I finally found a solution to my problem : I unlocked the device using flashtool-0.9.11's gui procedure, instead of flashtool's fastboot. It succeeded and I can successfully flash anything I want on the device.

[Q] XOLO Q500 Bricked. Qualcomm Snapdragon MSM8225Q device.

Hello guys, there is no specific forum for this device, that is why have started this new thread.
My xolo q500 is bricked. It stucks at the logo and doesn't go further. I was trying to install CWM recovery. But niether CWM nor TWRP not available for my device so i tried to flash CWM of some other device from the rom manager. It was of xolo q700. After flashing my device got shut down but stcuked at the boot logo when restarting.
All i wanted to do is to flash a custom rom. I rooted. I tried to flash it via the default recovery but it was not succesfull i dont know why. I googled and came up to know that i need to install custom recovery like CWM or TWRP to successfully flash custom roms. So when i flashed cwm of xolo q700, this happened....... It was all because of that other device's CWM..... and that recovery.img file was placed in the internal memory. So overall, i flashed it from the internal memory.............
Now my phone niether boots up normally nor boots in the recovery menu. It stucks at the xolo logo. I googled but i found unbricking methods for mediatek devices via sp flash tools but my device has Qualcomm Snapdragon chipset , so that didn't worked. Please help me how can i unbrick my device? Is there any method to unbrick qualcomm based devices?
I had that thought of not installing stuff of another device. But i niether found any custom rom nor recovery for this device. So i decided to just use another device's stuff. Yeah i know that totally crazy idea... but.....whatever when i plug it into PC it does not detect anything but when i plug it in pc after removing battery, its LED starts blinking. When this happened first time... Something like 'Qualcomm msm' was installed but nothing thereafter......

Huawei Y6, how to remove FRP?

Hi guys, i got the Huawei Y6 SCL-L01 phone and i wanted to install a custom rom, so i tried to install TWRP first, but since there wasn't a Y6 version (there isn't a Y6 version for anything pf ) i used the P8 version and it installed but when it rebooted the phone was stuck at a screen that say FASTBOOT & RESCUE MODE. The phone seems to be unlocked according to that screen but the FRP is loocked.
Things i've tried so far
Installed ADB latest version, extracted Recovery Cust System and Boot images from an official stock ROM.
Tried all available drivers from Google TP_Link and Intel for my phone.
The screen i am stuck does not work with ADB commands, the device is not recognized.
Fastboot commands work and it sees the device correctly, the problem is every time i try to flash the images from the stock rom i get FAILED message due to FRP Lock.
Format userdata and cache doesn't work either.
Vol + / - and Power button combinations also have no effect, it only shows that screen regardless of what i press.
I've searched the web and the XDA forums extensively since this happened and tried every possible solution i could find even if it was meant for another device.. no luck.
And here's my question, how can i possibly remove the FRP lock by only using fastboot?
Please somebody help, i am like half a day away from decorating the wall with this piece of ****
PS: I am not able to upload screenshots, sorry about that.

I'm stuck with this problem too. The exact problem. Have you found a way to fix it?
I have exactly the same problem with my Huawei Tablet.
If I boot with the original ROM and look in the "/log" - directory with adb shell, there is a cust.log. The contents say, that the specific ROM is not original or factory.
I think even the bootloader is unlocked, there is a kind of signature checking.
EDIT: @Asdforcer: Have you tried to boot the original boot.rom with "fastboot boot" - command?

MIssing Boot loader

Hello all,
I recently picked up a ulefone armor 2s and was attempting to root it and ended up bricking my device... i followed a guide for flashing the 2 variant not the 2s. I found a stock rom and ended up flashing it and got the device back to working status. I do want to root my device with twrp but i am unable to flash it because there is no bootloader on the device at the moment.
Powering up the device i get a message that says device is in a red state i am not sure what that means. I have found a copy of trwp that is corresponds to my chipset and kernel and want to flash it. Attempting to enter download mode or recovery just gets me to a black screen.
I have tried to flash the device using adb, adb doesn't detect my device. I have all the proper drivers, usb debugging is enabled and is oem unlocking.
Cpu-z says that i have an unknown bootloader and when i try to access it nothing happens
Is there a way to put a bootloader on it?
Thanks
-Malice
