Pico Neo 3 Pro Eye VR Headset A7H10. ROM & Firmware update problem / ROM和固件更新问题

Question

Hi!

My Pico Neo 3 Pro Eye VR Headset doesn't work after updating. I tried to reboot my headset several times but no luck.

I tried to reset via recovery mode and Wipe Data/Factory Reset. The procedure was successful but the headset doesn't start. So, I guess I should update my firmware via ADB (because my model has no SD card slot).

Please, send me the instruction how to connect my headset to Windows 11 with a computer cable, and the ROM file for updating headset via "Apply update from ADB" with ROM file.

My Android recovery information:
Product name Kona
Variant sm8 uns
Secureboot yes
Device state locked

你好！
请帮我一下。

我的 Pico Neo 3 Pro Eye VR 耳机在更新后无法使用。我尝试重新启动耳机几次，但没有运气。

我尝试通过恢复模式和擦除数据/恢复出厂设置进行重置。程序成功，但耳机未启动。所以，我想我应该通过 ADB 更新我的固件（因为我的模型没有 SD 卡插槽）。

请向我发送如何使用计算机电缆将耳机连接到 Windows 11 的说明，以及通过“从 ADB 应用更新”和 ROM 文件更新耳机的 ROM 文件。

我的 Android 恢复信息：

变体 sm8 uns

设备状态锁定

Dear developer,
Could you please tell us witch way do you upgrade the system? And from which version did your system upgrade, and to which version?
When you say the device doesn't start, do you mean that the device cannot be turned on?
Try holding down the power button for 15 seconds first to see if you can forcibly restart the device fi.

I try to upgrade the system via WiFi from version 4.3.34 to version 4.6.3.
After download complete, the system was rebooted.

After reboot the system was complete, the system entered to the FastBoot Mode.

If I holding down the power for 15 seconds, device enter to the FastBoot Mode (the system show to Pico logotype twice and then enter to the FastBoot Mode).

If I choose any FastBoot mode menu options (reboot or poweroff or any other), headset enter to the FastBoot Mode

Dear developer,
Have you tried to restore factory Settings in FastBoot mode? If not, please try restoring factory Settings in FastBoot mode.

Sure.

I tried these paths and all of them finished with no luck:
1. recovery mode, wipe data / factory reset, enter fastboot, reboot system now - no luck (system entered to Fastboot mode & device state is LOCKED)
2. recovery mode, wipe data / factory reset, reboot bootloader, recovery mode, reboot system, (see fastboot mode), start - no luck (system entered to Fastboot mode & device state is LOCKED)
3. recovery mode, wipe data / factory reset, enter fastboot, reboot to bootloader, start - no luck (system entered to Fastboot mode & device state is LOCKED)
4. recovery mode, wipe data / factory reset. Wait 2hours but nothing changed (I see only recovery menu)

fastootd info:
Android fastboot
Product name - PICOA7H10
Bootloader version - unknown
Baseband version -

Secure boot - yes
HW version - 0

If I click on Mount/system at Recovery menu, I saw an error:

Dear developer,
Sorry for the late reply. Have you tried the reboot now option in the mode?

---

Dear PicoDevSupport,
I tried to restore factory Settings in FastBoot mode. But, headset still at FastBoot mode.

Please describe step-by-step what exactly do you mean ("Fastboot Now option in the mode")

---

Dear developer,
Sorry about that, Is the Reboot Now option in the FastBoot mode .

---

Dear PicoDevSupport,
sure, after I selected Reboot Now option in the FastBoot mode, the headset reboot to FastBoot mode (nothing changed)

Also, please send me file for "Apply update from ADB" & "Apply update from SD card" options. And step-by-step instruction how can I "Apply update from ADB".

---

Dear developer,
Sorry, "Apply update from ADB" & "Apply update from SD card" cannot be used.
We suggest that contact the salesperson from where you bought the device.
Ask the salesperson to take a look at the device and see if he can help restore the system.

Dear PicoDevSupport,
please send me URL where I can download .zip firmware/software file & instruction how to update my headset from Recovery menu?
