Which part? the going immediately to the bootloader? THat is easy, you tried flashing a ROM and never cleared fb_mode... In the bootloader use fastboot and use this command command:
fastboot oem fb_mode_clear
and it should now boot normally without starting the bootloader each time.
For the bootloader unlock image, flash a logo.bin that is designed to cover it... you can't make it go away any other way even if you relock the bootloader
"system : there is no system"? Well, flash something.

How to resolve boot loop problem on android PumpKinx 10.1" tablet

I've android PumpKinx 10.1 tablet with 5.1 Lollipop android os.
I did take backup of its stock recovery image.
Since there is no custom recovery image for this device I tried to flash it with twrp recovery image. But after running below command, device goes into bootloop. I've tried many methods but no success.
fastboot flash:raw boot twrp.img
Any help would be highly appreciated. Thanks in advance.
maybe u have locked bootloader. First turn on oem unlock in developer options, then reboot in bootloader and type
Code:
fastboot oem unlock
Then confirm acion in the tablet whit volume up, then the bootloader now is unlocked.
Note: The tablet get soft reset. Make backup first.
Then try flash the recovery

Do you understand boot loop or not? First of all fastboot is already unlocked otherwise how I will be able to run above command and since my device is in boot loop then how can I go to developer option?

Just send them an email asking for stock firmware with flash tool, along with the purchase bill..
Or if it still has warranty, just go to the service center and say something like you over-charged the phone a complete night & since then it's not working and claim warranty..
Have you tried to wipe the cache partition or even factory reset???

Nexus Stuck on Google Logo

Hello guys, I dont know whats happening with my Nexus 5 right now. Its stuck on Google logo which appears during restarting of the phone.
I have tried everything. I try to go into recovery it dosent work. I tried changing it to CWM from TWRP still it stays TWRP i get errors while flashing .bat files like (error: failure to write). Please help been stuck on this since past 72hours. Any help to resolve this issue is appreciated. Thanks :crying::crying::crying:
If the bootloader is unlocked, relock the bootloader and reboot into fastboot mode. If the bootloader unlocks itself, the internal memory is probably damaged. If the bootloader remains locked, unlock it and flash 4.4 using fastboot commands.

OEM can be locked and unlocked. But the only problem now is i cannot override the previous partitions as there is an error "failed to write" i dont understand why is this happening this is also the reason i cannot get into my recovery as when i enter recovery it gets stuck for some reason.

Let's start with the bootloader.
Boot into fastboot mode, lock the bootloader, reboot into fastboot mode. Does the bootloader stay "locked" or does it go back to say "unlocked"?

I tried the 1st step by overwriting twrp with cwm dint work. Also ADB isnt connected. I tried to but just fastboot works.
I recommend flashing stock 4.4 using fastboot commands.
Stock ROMs are here: https://developers.google.com/android/images

I tried flashing new roms it says failure to write to cache,boot,recovery everything fails!
There is no way to erase partitions as it fails!
I would say the internal memory is damaged and will require a motherboard change.

Bricked Mate 9. Plz help

I deleted my bootloader. Whatever rom I flash it's just went into bootloop and when it boot the second time it boot into Huawei erecovery. My model is mha L29 cc636. I used to run on Android 8.0. Plzzz help
Try typing "fastboot oem relock (your phone's unlock code)" but this method will factory reset your device.

Fastboot won't work since I deleted my bootloader. I couldn't get into fastboot mode.
hmm.....I didn't;t know you could delete the bootloader.
If your phone still goes to eRecovery, then you couldn't have deleted your bootloader. (Fastboot is the stage 2 boot loader, which loads the various other partitions for startup, boot or kernel + ramdisk for normal, recovery or kernel + recovery_ramdisk for recovery, and erecovery or erecovery_kernel + erecovery_ramdisk for eRecovery.)
In any case:
Power off
Hold volume down while plugging into computer.
That should start up fastboot.

If the "orange state" is "Your device is unlocked and cannot be trusted", you will most likely have your bootloader unlocked.

No need to relock. What happens when you presses the button combination of fastboot mode (search Google)?

Take note that as soon as you re-lock the bootloader the bootloader simply gets forced to load phone's Stock ROM.
