Unbricking with QFIL gives "Sahara Fail" error. help!

[spirit_room]

I solved the same issue by using miflash tool instead of QPST which is a bit fragile in my opinion. You can google miflash to download it and it is pretty straightforward to use. Click "fresh" to find the COM port, then click "Browse..." to locate the folder which contains your unzip/unrar image files, then click "Flash". It usually only takes very short time. Enjoy!

BTW, I feel miflash works not only for Xiaomi phones, but all other Anndroid phones, because my phone is not a Xiaomi one. I used this one Xiaomi_Flash_20160401.zip from the offical site. I think the latest one should also work, but you need to try it out.

so i have a LG K20 (mp260) from MetroPCS, and like a fool, i flashed a rom that wasnt compatible...
its now hard bricked. my computer can only recognize it now as "Qualcomm HS-USB QDLoader 9008 (COM3)" in the "Ports" section of the device manager. the device itself cant turn on for nothing, there are no lights, no vibrations. but my computer can read it...

i have minimal knowledge on this stuff and ive been at this for almost a week now and how found nothing but the QFIL program that looked promising. ive installed all the appropriate drivers and give it the appropriate files (i hope):
Programmer: prog_emmc_firehose_8936.mbn
XML: rawprogram0.xml with the patch: patch0.xml
the files were manually extracted from my own phones stock .KDZ
i have seen others use rawprogram files such as "rawprogram_unsparse_without_qcn", and "rawprogram_unsparse". i dont know how to obtain these files and if they would help my problem.
(note: im using QFIL 2.0.1.7 and ive tried numerous previous versions:crying

im getting tired of seeing this log lol. but as you can see the problem (from i can see) is that its getting stuck at the "Sahara" bit. i cant seem to fix this to save my life. and ive littrally tried everything!
yes including putting the firmware files into the "bin" folder of the program and stuff like that...
fastbooting wont work either as the screen is always black and the computer never sees it as a device, but a port.

i turned to creating this post as a last resort, for if i cant find an answer here, im afraid ill just have to use the phone for parts or something:crying:. please! if anyone has suggestion or a solution that i haven't tried yet it would be truly appreciated!

Those with this issue must follow Teddy Lo post. Added to his;

1. Make sure firmware file names and types are the same in rawprogram0.xml partition path.
2. There are some programs that help Android tools to function well like java, python, Android sdk, netframe work etc must be installed.
3. When installing Qualcomm drivers choose Ethernet.
4. Device must be in edl mode like my case
5. Can also try this version of Qualcomm drivers and Qualcomm flash tool. https://mega.nz/#!6VYQnCxQ!5r76u_zxUJhNgX9UKj8iKKXbXNtnVID6029zAaVLoXk

I had been using it for sometime now without issues.

This error occurred because your bootloader is locked , YOU MUST ENTER 9008 MODE WITH TEST POINT WAY to bypass this lock. entering eld mode with buttons and fastboot is only for phones with unlocked bootloader.

Thanks, this comment saved me, my existing bootloader is already unlocked, so what i did was re-locked it and unlocked it again before download on qfil, the only issue I encounter is the when I login to flyme, it says, you have not logged out as another, and I cannot put my flyme account on the phone. Tried to update and wipe, factory reset/erase and everything but with no luck. BTW, Myphone is Meizu 16th, Thanks.

Was in a same dilemma. As it turns out, the whole process is perfectly fine, the only thing that's missing is connecting the phone to the PC (via USB cable) with only battery kept disconnected. The error "sahara fail" seems to be coming from battery kept connected throughout the flashing process.
