Questions & Answers
Q. Why is my phone unrepairable if i can get to fastboot?
A. By not being able to access fastboot means the preloader partition is damaged and SP Flash Tool will not work.​Q. Why is my phones not bootable.
A. It could be caused by many factors but mainly caused by failure in updating firmware due to no battery or incorrect flashing of ROM.​Q. Why is it so hard to recover meizu phones
A. Meizu phone uses the new mt67xx which is not supported by MTK droid tool causing problems for users to obtain the scatter file, and also the locked bootloader leading the users not being able to recover the devices the traditionally using fastboot.​Q. I have a m3 note can i use this method?
A. Yes if anyone gets there hands on the mt6755 scatter file for meizu. But if not No​Q. HELP ME IT'S NOT WORKING!!!
A. Calm down, follow the steps again, if not comment below.​Q. How do i brick my device

Any display? or just black?
What rom did you install? If official you might be able to get a replacement through warranty.
Try SP Flash Tools, instruction in the first post. Chances are low but test if it detects after pressing download.

i used DA_PL.BIN and got the same error, maybe bootloader is locked thats why this error?
The error shows when your device started before the software can flash anything. SP flash tools works with locked bootloader, maybe your preloader is 100% dead

Hi,
SPFlashtools fails to connect dead bricked Meizu M3S
Connecting to USB system recognizes as

But other ports including Preloader are not
Do I have any hope to recover phone?
After following these steps, one by one, no matter if all went OK, my phone (m3s) won’t boot and it seems it is completely dead now. It can’t turn on. Power button looks unresponsive. What should I do? Is there any help?
many thanks for this guide @bluecub1st . The problem I have with my M3s is that it boots perfectly fine and works well, i just cannot enter recovery by using Volume + and power, and flashing a new firmware from inside Flyme OS just reboots the phone. I can enter fastboot though no problem, but i tried to do the SP Flash tool method listed and I just get this error message:
ERROR : S_TIMEOUT (0x412)
Any ideas how to fix this and get my recovery back? Really need some help so i can flash flyme 6...

Dead boot Android!

Hello!
I accidentally flashed wrong boot image on my phone via twrp and then I tap on reboot/system after that phone didn't boot.
No response.
Not turning on even I reinsert the battery!
No going to fastboot or Recovery mode!
SP flash tool didn't able to flash rom.
It always shows error.
I think I need to re-programme emmc chip?
Boot information stored in emmc right?
Is it ok/right?
Or is there another method to revive it?
(please help about this issue)!
Phone:- Infinix Smart 3 plus.
OS:- pie/9.0
CPU:- MTK 6761/Helio A22.

Just reflash the Stock boot.img via fastboot if available.
Or Flash the whole stock ROM via TECHNO FLASH TOOL it is the only Flash tool compatible with TRANSSION DEVICE. Sp doesn't work... And make sure you have installed proper drivers

*Preloader USB VCOM

Bricked Ulefone Armor 8 Pro

Hi everyone, I tried to flash a patched Magisk boot image on my Ulefone Armor 8 Pro via fastboot but the device is now stuck in bootloop. I have already read some threads about trying to flash the stock firmware using the proprietary SP Flash Tool, but the phone doesn't remain in download mode for more than a few seconds. I can't even boot in recovery/fastboot mode again to try to flash the stock boot image since the phone just keeps rebooting. If someone could give me a hint it would be really appreciated.

You need write the model of device.
Currently I know of 3 models: 4GB RAM(Armor 8); 6&8GB RAM(Armor 8 Pro).
So with the correct stock ROM you can flash the device.
To use SPFT you need to specify which OS you have: Linux; Win7_8_10; other
This is to know if you actually installed the USB MTK drivers correctly and if further action is needed.
Also, write if you have the device with the bootloader locked or unlocked.
I have the 6GB RAM and have downloaded a time ago the GQ3090RH3_KSX70H_Ulefone_20210902_V01(Non-EU).zip file aka stock ROM. That's aka Non_EEA model. In the Ulefone site have SP_MDT_exe_v3.2048.02.00(Client).zip aka flash tool.
You used that tool?
Thanks for the reply. I have the model with 6GB of RAM as well and I am currently trying to recover my phone by using Windows 11 in a virtual machine. The bootloader is unlocked and I tried to flash the EU version of the stock ROM (GQ3090RH3_KSX70H_Ulefone_EEA_20210902_V01(EU).zip) by using SP_MDT_exe_v3.2048.02.00(Client).zip (after installing the required drivers), but as I have already specified I can't boot in download mode for more than a few seconds. My computer recognises the device as "MediaTek MT65xx Preloader" but the phone immediately reboots and I am not able to flash the stock ROM.

Win11 is not good to use SP tool.
Maybe using Win10?!
"MediaTek MT65xx Preloader" is normal but need installing drivers correctly. You can try this: Driver_Auto_Installer_EXE_v5.1632.00.zip - 8.8MB
Reboot VM and try with the device turned off!
For using SPFT or SP_MDT your device not need in the bootloader mode. Device turned off - conect USB - look about USB PORT COM - Scan - Start All
If you not know how to do so Read Upgrade software guide for factory assembly line.pdf
Here file and more about: Upgrade tools and USB driver - Armor 8 Pro
___________________________
UP: Maybe SP need more than you know.
I used the SPFT and worked good to me with Win10.
May be SPFT can help more than SP: SP_Flash_Tool_v5.2124_Win
For using SPFT your device not need in the bootloader mode. Device turned off - open sxcatter file - look for Download Only option (NOT use FORMAT+....!!!!) - now with the device turned off conect USB - press DOWNLOAD (Ctrl + D).
Well, you saved my phone. Thanks for the help, I really appreciate that. I installed Windows 10 and the drivers you linked me and via SP Flash Tool I managed to flash the stock ROM after connecting the device with a USB cable. Thanks again.
How do I get this phone into download mode? Cannot seem to get it to flash
I've followed your tips but I cannot get the phone recognized by the flash tool.
I've collected full details here: https://android.stackexchange.com/questions/248035/bootloop-in-ulefone-armor-8-pro
Can SPFT be used with Linux?

Question A12 SM-125F/DSN only shown as mediatek usb unbrick

Hello! I have the phone from the title and I need a scatter firmware for this model to flash it with the SP Tool program, to unbrick it. I can't flash it with Odin, because download mode or recovery does not work. I have working MT Bypass tool and drivers installed correctly and phone is detected as mediatek usb but I need the correct firmware. Can somebody share a link to a firmware like this or a complete backup scatter firmware from a working phone, for this model?

mr-mobiles-city.blogspot.com
i found this website somewhere in the internet
That archive is password protected and the password "gsmVNtool" is not working...
I have this yt video link
But just curious what did you do to the device before hardbrick(eg.Install TWRP,flash firmware?
How did you brick it?
It's my father's phone. I suspect an update has started and the battery has been discharged. The phone restarted continuously and does not charge the battery. Showed only the charging sign but without the charging percentage. I tried to flash it with odin and nothing changed. Then I used SP Flash Tool with a firmware found on internet an choosed to format all. But here was my mistake, because that firmware was for A125U1. Now, I followed your post and I converted the last firmware but when I try to flash the files with sp tool, i get errors , something with image too large, invalid header, etc... I'm at work now, but I think that you know what I'm reffering to... Thanks for the help.
Is there a way to unlock the bootloader without the phone working with ODIN? I'm trying to write the latest firmware version, (A125FXXS2BVA3_A125FOXM2BVA3_ROM), with SP Flash Tool, because I can't downgrade back to Android 10, and I get the errors: "STATUS_SEC_IMGHDR_TYPE_MISMATCH; Verified boot is enabled. Please download signed image or disable verified boot."
If I try to write a firmware version with Android 10, SP Flash Tool returns the error: "STATUS_SEC_VIOLATE_ANTI_ROLLBACK".
