Go 7 attempted root and now stuck on boox logo

[jd27]

Hi,

I had purchased a new Go 7, and attempted to root the device using this guide noting that someone on reddit stated that the same guide worked for the Go 7. My device now unfortunately does not boot - it shows the BOOX logo but nothing else happens.

I have bought a EDL cable, and can still access EDL but not adb or fastboot.

Could someone provide any advice on (a) how I can get back a functioning device, and (b) what I should do to be able to root this device?

What I did to get into a not working state:

• Bought a brand new device, did not connect to wifi.
• Turned USB debug mode on
• Downloaded edl utility from here (https://www.temblast.com/edl.htm), and using this loader for Go 7 (https://www.temblast.com/ref/onyxldr.htm). Note for subsequent commands, I didn't use /u as I read that Go 7 does not use UFS.

.\platform-tools\adb.exe reboot edl
.\edl.exe /lgo7-2.bin
.\edl.exe /g
.\edl.exe /r /pboot_a go7_boota_unrooted.img
.\edl.exe /r /pboot_b go7_bootb_unrooted.img
.\edl.exe /z
.\platform-tools\adb.exe install magisk.apk 
(I then used magisk to patch boota_unrooted.img and bootb_unrooted.img)

.\platform-tools\adb.exe pull
.\platform-tools\adb.exe reboot edl
.\edl.exe /w /pboot_a magisk_patched-30600_vn0oa_boota.img
.\edl.exe /w /pboot_b magisk_patched-30600_8rklr_bootb
.\edl.exe /z

At this point the device restarted and is stuck on the BOOX logo. I can access EDL, but not adb devices or fastboot.

What I did to try to recover (Method 1 - did not work):
Using an EDL cable:

C:\Users\Em\Desktop\boox-root> .\edl.exe /lgo7-2.bin
Found EDL 9008, handshaking... version 2
HWID: 0013f0e100000000 (x3), JTAG: 0013f0e1, OEM: 0000, Model: 0000

.\edl.exe /w /pboot_a go7_boota_unrooted.img
.\edl.exe /w /pboot_b go7_bootb_unrooted.img
.\edl.exe /z

Same as above, device is stuck on BOOX logo.

What I did to try to recover (Method 2 - also did not work):

• Downloaded the latest firmware for Go 7: http://en-data.onyx-international.cn/api/firmware/update?where={"buildNumber":0,"buildType":"user"," deviceMAC":"","lang":"en_US","model":"Go7","submod el":"","fingerprint":""}
  
• The JSON response stated this was Version 4.1.1:

  "fingerprint":"Onyx/Go7/Go7:11/2025-11-10_16-08_4.1.1-rel_1110_d8cf44fd7/6191:user/release-keys","buildType":"user","buildNumber":6191,"buildDisplayId":"2025-11-10_16-08_4.1.1-rel_1110_d8cf44fd7","

• Ran decryptBooxUpdateUpx (https://github.com/Hagb/decryptBooxUpdateUpx) to convert update.upx to update.zip. Extracted to get payload.bin
• Ran payload-dumper-go (https://github.com/ssut/payload-dumper-go) to get the following files: abl.img, boot.img , dtbo.img , modem.img, odm.img, product.img , recovery.img, system.img, system_ext.img, vbmeta.img, vbmeta_system.img, vendor.img, xbl.img
  
• Based on what I read for other android devices, I used edl to rewrite as:
  
  1. boot_a / boot_b: boot.img
  2. vbmeta_a / vbmeta_b: vbmeta.img
  3. vbmeta_system_a / vbmeta_system_b: vbmeta_system.img
  4. dtbo_a / dtbo_b: dtbo.img
  5. abl_a / abl_b: abl.img
  6. xbl_a / xbl_b: xbl.img
  7. recovery_a / recovery_b: recovery.img
  8. modem_a / modem_b: modem.img

I'm stuck here because guides tell me to also write 'super.img', but I don't have this file.

Are there any suggestions? I'm grateful for any advice people can offer, and thanks in advance.
