I’m not having any luck. Tried to reflash, no dice. I do notice a quick jump from 20% to ~50% whilst writing; but the buffer/chip check says it’s fine.

I’ve got a ChuwiHi10 Q64 G42151104788

I have downloaded the 3000-5000 bios.bin which should be fine.

No dice. No LED, no boot. The USB ports will start going on and off (when fan is inserted, it will spin up, spin down, spin up etc).

I’m out of ideas. I will charge it overnight, maybe a miracle happens. I’ll be sure to let you folks know.

[UPDATE]

Charing overnight did not make a difference. I dug up my external LIPO charger and connected it straight to the Hi10’s battery. It reads as fully charged. I will now try to drain the battery completely and recharge it. But I think it won’t make a difference.

Okay, another update on my dead Chuwi.

Today a new 1.8 voltage regulator arrived. I disconnected the battery, hooked up the USB programmer and clip thing and… halleluja, it detected my chip! Hurrah! All this time I was using a faulty voltage regulator.

So. Okay. Erased, blanked, checked, wrote the BIOS and verified it. I’m quite sure I have to correct 64-bit 3000-5000 bios file. So I felt happy when all went OK.

So then I removed the clip, I hooked the battery back up, I tried to power the tablet… nothing.
I then tried to charge the tablet… nothing. No lights, no screen, no nothing.

It WILL do something; there is power to both USB ports (plugged in a xiaomi LED and a xiaomi fan) when the tablet is switched on. But it flashes. The light flashes and the fan spins up spins down spins up spins down.

So appearently something is still wrong. Any ideas?

@Bill
Yes and yes, plus all hardware parts listed in Lupo’s posts – connected them in the exact same way. Red cable is on the little indent where it should be.
I ordered a new clip, which has not arrived yet. If that fails as well, I might consider buying a slightly different programmer. Or I might toss the damn tablet in the bin after all :p

Strange though. I just tried my setup again. I still can’t identify the chip, it will say ‘Detection fails, cannot find the chip’. I can, however, read it, erase it and blank it. I cannot seem to get it to write (some timeout occurs) or verify.

Well, today the last of the suggested components arrived (the clip-to-the-chip thing). I had no luck identifying my Chuwi Hi10 chip with the CH341A programmer software; although it’s drivers were installed without problems and the programmer software would read ‘connected’. I tried two computers (both win10), but no luck. Things would happen when clicking ‘write’ or ‘erase’, but I don’t think it actually did much. It would even start erasing without the clip attached to the chip.

I’m guessing my clip is a dud. One of the pins seems to be too short. I’ve ordered a new one. If that fails as well, I’ll throw this darn tablet in the bin and never, ever, EVER buy one of this brand again. (Although I was infinitely dumb to start messing with the BIOS on an otherwise fine tablet in the first place)

I also managed to mess up my Hi10’s bios settings – tablet wouldn’t turn on anymore after altering some. Unbelieveable there is no jumper or reset button to clear CMOS settings. Thank you Lupo for your detailed description, I have ordered the parts you suggested and will try to fix my tablet when they arrive.

I tried amiduos too.  It works, but lags too much for my taste – both lollipop and jellybean. Also the VM tends to crash when the tablet goes into standby. If you really need Android it sort of works, but in no way fluent enough for me to be acceptable.

It seems there is a new BIOS available for download; but I can’t get past the login for some reason. No idea for what it may or may not bring, or will or won’t support. If anybody is feeling adventurous:

Hi everybody,

I’m also the proud owner of a Chuwi Hi10 (blue USB / 64 bits version / ordered from banggood). I received it about a week ago. So far, I don’t have too many serious complaints. It feels reasonably snappy, there is a big difference in using MS Edge vs firefox though, edge is much more fluid.

– I had some trouble changing the windows display language from English to my native language (Dutch). For some reason the language pack failed to install properly through the regional settings menu. Eventually fixed it by manually downloading some .cab file and using the windows command ‘lpksetup.exe’.
– I have a slight screen flicker every now and then, but I have not been brave enough yet to flash a new bios.
– Wifi is somehwat unstable. Signal strength seems fine, but waking up from sleep the tablet either fails to connect properly (‘no internet’) and sometimes it won’t allow me to toggle the wifi adapter off/on. Maybe it’s a driver issue. Tends to get annoying a bit.
– I can’t seem to pair properly with an el cheapo bluetooth keyboard. That may either be the el cheapo’s keyboards fault or maybe the default microsoft bluetooth stack isn’t optimal. It’s not a big deal really, I’ll order the dock eventually.
– Inbuilt speakers are really really poor. It’s a bit better with the equaliser trick described on the forums, but I’d use it for notifications only. Headphones or a bluetooth speaker are advised when playing back media (my Earson ER151 paired fine over bluetooth, although it lags about half a second when playing back movies – it’s better to use the 3,5 jack).

I wouldn’t mind trying android on this thing, but it seems we may never see that dual boot feature. Support for Chuwi’s seems to be on the lower end of the spectrum, not many forums discussing this particular model in detail.
