Is there any way to update it?

Yes.

Code:
// backup bios
fptw.exe -d pipo-w2-old-bios.bin
// backup windows key
fptw.exe -a 0x580000 -l 0x100 -d msdm.bin
// flash new bios
fptw.exe -f I8080_MIPI_V3.1.5_FT_GC2235_OV5648_LogoPiPO.bin
// restore windows key
fptw.exe -a 0x580000 -l 0x100 -f msdm.bin
I downgraded my BIOS to the original version, which is the one you have, and both cameras work fine. This means that a BIOS update might not fix your issue. Did you try deleting both camera device from Device Manager and have them re-detected? Maybe also do the same with "Intel(R) Imaging Signal Processor 2400".

just register to say thank you, the rom works out well, space saving.
----------
another thing is about downloading from baidu pan,

from my experience, download from baidu pan need no account nor install specified software, you just have to select and download one file at a time (no folder), each file no more than 1G (maybe 2G),works with IDM.

I am Chinese btw.

UPDATE 2:
Can't reinstall GC2235 and Intel hd graphics panel doesn't work.

UPDATE:
After updating bios, the camera that wasn't deleted is now working, and the las two unkown devices have disappeared, now i'm trying to get gc2235 back to work.
Thanks for your help.

I didn't try updating the bios but tried to delete and detected and it didn't work.

Now i see an error saying Device_power_Failure.
Hardawre IDs
OV5648 =INT5648
GC2235 = INT33F8

Also i have two more unkown devices whose HW IDs are INTCF1C and USB VEN_8086.

PiPO W2 front camera problem - looks like a film negative
I have only just tested the front camera - 2 months after getting it - and there is a problem. The foreground looks like a film negative.
I have uninstalled and reinstalled the Intel Imaging Signal Processor 2400 driver, but it makes no difference.

What can I try next?

Yesterday I received my Pipo W2 tablet. It came pre-installed with an activated "Windows 8.1 with Bing". I updated the BIOS to version 3.1.5 (I8080_MIPI_V3.1.5_FT_GC2235_OV5648_LogoPiPO.bin) and used a USB thumbdrive to re-install Windows, using the most recent version available on the Pipo website. After installation, Windows refused to activate (error 0xC004C003). I used "Read & Write Utility" to look for the Windows key in the ACPI/MSDM table but the MSDM table was nowhere to be found. Luckily I had made a backup of the original BIOS before I updated it. I flashed the original BIOS back, rebooted and the MSDM table was there. I tried to activate Windows again and it worked. If it wasn't for that backup I would have not been able to activate Windows again.

Do you have to re-install windows after updating the BIOS?
