Not sure what happened but my tablet doesnt turn on anymore, i had linux installed once, then switched back to windows, everything was fine. I also want to note that I did remove the android partition and left only the windows but everything was working fine but one day i was in the bios and reset everything to default, then rebooted and it stopped turning on.
There is no lights when I plug it in to the charger either
Serial Prefix: PQ64G421610
I need the bios file, also I need to know which external programmer works and that I should buy (from aliexpress)
I also need to know an alternate method to install or reset the bios.
I have a similar problem.
Model: CWI529
S/N: PQ64G42161101925
BIOS chip: W25Q64FW
After quite a while without using my Hi10 Pro, I have not been able to get it to boot again.
I have tried all the methods of pressing the different buttons and none of them worked.
I have noticed that when I connect the power via USB-C, the tablet emits a slight heat in the area where the motherboard and CPU are.
I have found that, without booting, it consumes 800 mAh from the charger.
A few weeks ago I took the tablet apart to check the battery status.
When I measured the battery voltage it indicated below 3V.
I read on a forum that if the tablet had been connected to its keyboard, it has a slight consumption that ends up draining the battery and, indeed, the whole time I was not using it it was connected to its keyboard.
To check if the battery was in good condition, I unsoldered it from the motherboard and connected it to a charger that would allow me to see how many mAh it held and how much it discharged. After doing the test, I got a result of about 6,500 mAh both charged and discharged.
I came to the conclusion that the BIOS had probably been corrupted somehow, so after getting the .bin file for my tablet.
I came to the conclusion that the BIOS had probably been corrupted somehow, so after getting the .bin file for my tablet (thanks @manonegra222 ), I unsoldered the chip, backed up its contents, and then flashed the new version.I have tested the 1.8V module with the CH341A programmer + it reads and writes the BIOS without any problem.
But the tablet still wonât boot.
Iâm waiting for 10 W25Q64FW chips that I bought at AE in case the one installed in the tablet has any defects.
Any help would be appreciated.
But I havenât solved my problem.
I received 2 IC W25Q64FW that I buy in the case the installed in the tablet is wrong.
I backup the info contained in the original bios and flashed in the new one, without exit.
I flashed the bios contained in the âHi10 Pro (P) Z8350 BIOSâ file in the original IC and the new one without exit.
I canât flash the bios if the IC is soldered to motherboard. The programmer is not recognized by the PC.
I connected the tablet directly to a lab power supply. I selected 3.9V (similar to a LiPo) and when I power it, without pressing any buttons, the Hi10Pro consumes 1.5Ah.
If I hold down the power button for a few seconds, the consumption drops to 400 mAh. And if I hold down the power button for a few seconds again, the consumption goes back up to 1.5Ah.
I made this little video.
Hola @otraver, Âżconseguiste resolver el problema?
Creo que me sucede lo mismo, como describo en
Por culpa de Windows parece que se ha brickeado mi Chuwi CWI529 Hi10 Pro.
No he llegado aĂșn a tanto pero me planteo intentar lo que has hecho tu programando el W25Q64FW.
Cualquier orientaciĂłn serĂĄ bienvenida.
Muchas gracias.
Hello @otraver, did you manage to solve the problem?
I think the same thing happens to me, as I describe in
Because of Windows it seems that my Chuwi CWI529 Hi10 Pro has been bricked.
I havenât gotten that far yet, but Iâm considering trying what youâve done by programming the W25Q64FW.
