Hello MobileRead Community,

I’m reaching out for assistance with my BOOX Go Color 7 (Gen II). I’ve been attempting to interact with the device in EDL (Emergency Download) mode but have encountered several obstacles.

Device Details:
• Model: BOOX Go Color 7 (Gen II)
• Processor: Octa-core (specific chipset not publicly disclosed)
• Operating System: Android 13
• Storage: 64GB 

What I’ve Attempted:
1. Entering EDL Mode:
• Used adb reboot edl to reboot the device into EDL mode.
• Device appears as “Qualcomm HS-USB QDLoader 9008” in Device Manager.
2. Using Renate’s EDL Utility:
• Ran edl.exe /u /r /pboot_a boota.img /t but received the error: Found EDL 9008, configuring... bad XML

• Attempted to load various firehose loaders, including palma2.bin, with the command: edl.exe /lpalma2.bin

• Received the following output:
Found EDL 9008, handshaking... nope, resetting... version 2
HWID: 0013f0e100000000 (x3), JTAG: 0013f0e1, OEM: 0000, Model: 0000
Hash: d40eee56f3194665-574109a39267724a-e7944134cd53cb76-7e293d3c40497955-bc8a4519ff992b03-1fadc6355015ac87 (x3)
Sending palma2.bin 100% ok, starting... ok, waiting for Firehose... ok

• Subsequent attempts to read partitions resulted in:
Found EDL 9008, configuring... ok
Requesting info on LUN 0... no ack/nak

Challenges:
• Unable to find a compatible firehose loader for the device.
• Uncertain if the device requires a signed loader or specific authentication.
• Limited information available on the device’s chipset and EDL compatibility.

Request:
If anyone has experience with the BOOX Go Color 7 (Gen II) or similar devices, I would greatly appreciate guidance on:
• Identifying the correct firehose loader for this device.
• Understanding if the device requires a signed loader or additional authentication.
• Any alternative methods to interact with the device in EDL mode.

Thank you in advance for your assistance!
