Hi, i also had this problem...
At first you must unlock the boot loader than you can install cwm from ROM manager. (I did it so)
Try to search Google for another boot loader unlock. Then it must work Good luck

solved
I opened the bat with notepad and saw the location must be in C not on desktop..
http://www.lg-phones.org/how-to-unlock-bootloader-on-lg-optimus-l7.html try this
Sent from my LG-P700 using xda premium
the solution is to have the .img file in c:\, not on desktop
You must have adb.exe and the .IMG in one directory then it must work

Hey, I got the same error in my old L7, but I had the stock rom and it appeared after my phone ran out of battery; when I tried to charge the battery via plugging to alternate current i got that error...
Is there a way to revive my phone without losing all the data in it?

Probably bricked galaxy y s5360

My galaxy y is bricked. There are alot of threads but i couldnt find one that really suits me. All the fixes require entering recovery or download mode. But my phone wont enter either.
I was using Hyperion 8. It stopped working after sometime. At first i could access recovery mode but couldnt clear dalvik cache. Now i cant access it altogether. Any chance of revival? I bought another phone. I am just trying to learn to fix a bricked phone, and maybe put it to some good use other than.....well a brick......

You can easily install stock rom of GT-S5360 via ODIN.
Hope it works.
How do i do that if i cant access download mode? I tried vol down+power+home but instead of download mode, the samsung logo comes up and then the phone does nothing
You cannot access download mode because your device has this combo disabled,
a download mode JIG (samsung has lot of JIGs and testpacks) cans make the phone access this special mode.
Even if the combo is disabled.

This sounds promising. I will definitely try it out. Thanks in advance.

It is still locked or you don't the false, false, false? After oem info it said failed and then try flashing twrp makes no sense
Reflash stock fastboot rom with miflash or use a deep flash cable. And then unlock it correctly
If nothing works you have to open your device and use testpoint method.
really nothing works.
miFlash gives me an error in red.
I already tried with the flash cable qualcomm but the phone when it vibrates it displays the MI logo and is off.
I tried recovery twrp.img but still the same error message
Method MiFlash:
Rom FASTBOOT for Redmi 4 prime: markw_global_images_V8.5.4.0.MBEMIED_20170925.0000.00_6.0_global

Fastboot method won't work as your bootloader is locked. Try with deep flash cable or test point method.
Trying to flash twrp also not gonna work.

I tried the deep flash cable:
click on the + and - button of the volume
plug in the phone and click on the button of the deep flash cable until the phone vibrates ... except that ... when it vibrates it displays the MI logo and ends ... but it is visible on the manager peripheral
Don't use "wipe_all_except_storage".
Use wipe_all only.

You can explain to me please
Nobody can help me?

so i destroyed my 6t for good.

so i took some break from android for couple of years and it seems somethings have changed since then, i had oneplusone so rooting wasn't new to me, but i got my oneplus 6t rooted it straightaway i had some issues with TWRP not sticking after i flash and had some issues were i couldn't find the directory to install roms but all that was fixed, had some other isues with using my banking app but that was sorted a swell so i was having fun.
a mouth or so ago i was wanting to get rom and my TWRP wasn't there it kept rebooting into fastboot menu, so i tried to flash TWRP again and it wasn't working so i messed up with boot img with all sorts of command lines related to flashing boot img, now my phone is dead for good i don't see how it can be fixed when the boot is corrupted i cant even boot into fastboot.
when i tired to boot into fastboot it wont work it stuck in that unlocked bootloader screen i have tried every combination available and it reboots into that. please help if you can.
please if i didn't explain my self properly ask away i just forgot what i did it been a while.

Try MSM tool
As mentioned, neither Fastboot or recovery need to work for the MSMTool to work.
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool.
Note the screen wont do anything, the phone will just be recognized by the MSMTool.

Yeah, OnePlus is one of the only phones that is truly un-brickable. Even Google pixels do not have working MSM tool.

Super Ultra Brick

I tried Unbricking my Oneplus 8 pro using MsmDownloadTool. 4 seconds after Msm run I stopped it, and I got this...

This is caused by download interruption. Recommend you use download tool try again.
You need to confirm if there is failure message on download tool or not when you see this error.
Also please check if you disconnect USB or click stop button when the download is not finished yet.
You can press any key exit this message.

It shows up whenever I try to reboot or go to recovery mode. Nothing works now and USB cannot be recognized except for Fastboot but it didn't help me with booting or flashing anything.
Any Idea?

Did you try to flash a fastboot rom?

Yes I did. It starts flashing well until it requests rebooting into fastboot. Once the phone reboot it goes back to that error message.
