Hi,

I was trying to follow https://www.hovatek.com/forum/thread-13347.html tutorial for my "Tecno Spark 7 Pro".
I have done the same with some other mtk devices too in the past.
But now with my Tecno phone, miracle gets stuck at "Connecting to phone, wait".

The phone chipset is "mtk6769". (Check attached "Screenshot_20210605-054547.jpg")
I have tried many things but no luck.

Do you have any idea what can be done regarding this? (Please check my attachments for full details)
Thanks.

Uninstall then reinstall vcom drivers
also check the phone usb port for faults

you won't be able to backup firmware from this device atm
firstly, miracle thunder 2.82 doesn't support the chipset mt6769
da file for kf8 isn't available and neither is a working exploit for mt6769 in mtk bypass @ https://github.com/MTK-bypass/exploits_collection

Thank you very much for providing the information to clarify it.
So that kind of means I can't do anything else than just waiting...
I will keep an eye here, thanks again.

exactly, you can always check the exploits page on github if your chipset type has been added

Got it.
By the way, suppose the exploit was made.
So, what will I do with the payload bin file?
Thanks.

run mtk bypass to confirm that it can successfully disable secure boot on your phone ; refer to https://www.hovatek.com/forum/thread-37957.html
if this is successful then you can attempt to backup using wwr mtk + sp flash tool method @ https://www.hovatek.com/forum/thread-21970.html : you'd need to add the chipset to the tool

Hello again, I was able to bypass secureboot protection via that mtk-bypass-tool.

But in SP-FLASH-TOOL when I would select the primary scatter file created by WWr it would tell me something like "MT67 platform not supported yet, please update sp-flash-tool". So I changed the platform from "MT6769" to "MT6768" since both got same "hw_code" (see: https://github.com/MTK-bypass/exploits_c...-856729479 and https://github.com/MTK-bypass/exploits_c....json5#L76)

But then I have a new issue which says:
""
ERROR: STATUS_PRELOADER_INVALID (0xC0030004)

The preloader file format is invalid!
[HINT]:
Please try another official load.
"""

First I have tried with "0x80000" "partition_size" in both scatter file and ReadBack (which ended up my phone being stuck in the download mode along that error).
Last night the phone revived and I tried again with low-battery power but with "0x40000" as the "partition_size", didn't make any difference.

Any Ideas what should I do now?

Thanks.

you'd need to have a preloader for any kf8 and include it within sp flash tool before attempting readback ; refer to https://www.hovatek.com/forum/thread-439.html
you can download the firmware @ https://www.androidfilehost.com/?fid=149...7586347824 ; you should find preloader within
