Does format and download in spflashtool work? Or return error

they sent me a new scatter file and it works for download even for unsigned images never tried format but i dont see why it should work

does anyone have experience adding twrp to devices. the twrp boot image i have doesnt boot. though it was able to flash gapps.

also on this device adb deoesnt start until after the end of the boot proccess so i can never diagnose what the problem is when i make modifications. is there a way to change this

i was able to flash us bands though i havent tried my sim card but it should work as it flashed and booted

If you are able to (I can’t) try format and download and let me know (write down device identifiers first. Would be invaluable to have a signed ROM

you want a signed stock rom ?? for this new device

I’m asking if that one is signed, yeah

Can’t write any which way in the guide until we know

So that’s why I want you to try format+download

the one sent to me by the factory one is signed. when i flashed it using just download (flashed the preloader) it locked the bootloader (there was no orange state warning and in dev setting it showed locked and i had to relock with mtkclient)

Interesting. Can anyone confirm this is all we need to know?

Or do we need to verify format+download

Simple. Avb flags were set to 0

dont know what that is - but your saying the bootloader was unlocked

i had claude read both apps decompiled smalli and it says they are not spyware

● MDMConfig

One-line summary: A simple on/off switch for the modem monitor service.

What it does:

  • Provides a UI with a toggle switch and button
  • Starts or stops the native md_monitor service
  • That’s it - nothing else

Think of it as: The power button for the modem diagnostic system.


MDMLSample

One-line summary: A diagnostic tool that captures and decodes raw data from the modem/baseband chip.

What it does:

  1. Connects to the modem via MediaTek’s HIDL interface
  2. Subscribes to “traps” (events/messages from the modem)
  3. Receives raw binary data from the baseband processor
  4. Decodes it into human-readable format
  5. Saves the output to a local text file in the app’s cache folder

Types of data it captures:

Trap Type What it is
OTA Over-the-air network messages
EM Engineering mode diagnostic data
ICD_RECORD Protocol log records
ICD_EVENT Protocol events
PSTIME Timing data from protocol stack

Think of it as: A packet sniffer/logger for the modem, used by engineers to debug cellular connectivity issues.


In Simple Terms

App Purpose
MDMConfig Turns modem monitoring on/off
MDMLSample The actual monitoring tool that captures modem data

Both are developer/engineering tools that shipped on your phone but serve no purpose for regular users.

Neither manifest contains:

  • android.permission.INTERNET
  • android.permission.ACCESS_NETWORK_STATE
  • android.permission.ACCESS_WIFI_STATE
  • Any network-related permissions

should i trust this

So I too have purchased the new version of the Qin I was able to unlock the bootloader with not an issue and I was also able to flash all of the ROMs without a problem using SP flash only problem is is that yes the hardware must be different because the display does not come up correctly. I did not make a backup so I don’t have anything to refresh it if anybody has a complete backup would be helpful right now it boots up to what looks like horizontal colors on the screen kind of like a boot loop only without detecting the correct graphics drivers looks like. Any help would be appreciated I believe it’s just need to repackage the kernel for this device since I’m not a programmer I can definitely use a working firmware even just to get it back to normal state.

had the same issue and same rainbow colors try flashing this

this is the non googled rom for newer devices ath the very beggining of this post i posted a full backup of the gooled rom for new devices

Thank you I’ll give it a shot
