Possible solutions (fixing bugs and dead tablet)

[Bùi Anh Tuấn]

Hi Philipp, thanks a lot for your help!
I have revived my hi8 pro 🙂
But unfortunately i cannot find a way to update the bios, the battery still has calibration problems, can you give me an advice, thank you!

Mine arrived yesterday, didn’t even boot to windows, got the loading screen twice, then only the LED was working, now it’s completely dead.. I’ve charged it for over 12h, still no signs of life. Do you guys have any other ideas before sending it back to gearbest? I’d try opening it up and reconnecting the battery but I’m afraid they won’t accept it back then :(.

Also about that BIOS thing, I found an update here, try it out and let us know if it works?

 

EDIT:

Also I’ve noticed an odd thing. I left it with the charger disconnected for the night but in the morning it was (and still is) warm near the camera..

You gave me hope… but nothing, I’ve sent mine back to Gearbest today. Will probably flag them on PayPal too just to make sure I see some money.

I am a dead Chuwi hi8 Pro tablet owner… I buyed it from Gearbest and it works fine when i take it from package.

Recharging wont help, tablet is dead. No lights when connecting to charger. Charger works fine.

Sending back to gearbest cost to me 35 euros, and there is possibility to lost package in travel…

I’m in the same boat, to send mine back is around 40 euros to Aliexpress, my screen is messed up and the tablet if the battery is under 50% sometimes doesn’t power on.

I have posted mine, cost about 25 euro, possibly not worth it but it’s the principle. Now I’m wondering what to buy instead? A working Hi8 pro is probably a great tablet to own, I just wish I had one!

Hi, I have the same issue, my tablet is not booting/starting sometimes. I also even don’t know if the battery is fully charged. Do anyone have some solution?

Hey all. Well, I ran into some issues when going into the bios and enabling all the options. I modified some of the graphics, cpu, power and a few other options, trying to up the performance. I changed the graphics to all to 512mb dedicated and I did a bunch of other setting like turning off the throttling and changing the ram to 1866mhz. Well after modifying enough stuff, my chuwi didn’t want to boot anymore. No more bios splash screen, no more nothing, except a kind of “lit” blackscreen. I did the hit the power button 3 times and then hold it and I hit a combination of the 2 buttons every way possible. I got it to boot up after about 30 minutes of messing around with it. I did flash the nvram with the amibios windows tool and rebooted, nada, still didn’t get any bios splash screen or windows. Tried the buttons for another 30 minutes, nothing. Then I grabbed my micro-hdmi to hdmi adapter and thought “why not, it probably won’t do anything, but I’ll try it”. I plugged it in, hit the power, my lcd lit up when I did, still no bios splash screen, but wham!, it booted right into windows. The tablet screen was not showing anything, but the external lcd was. Yippe! Now what do I do? Tried flashing the whole bios with the amibios tool, no go, crashes in windows. I had to change the bios back to defaults. I went to start-settings-updates-recovery, reboot to recovery, then I selected boot into uefi firmware settings, it rebooted, showed me the uefi bios first page for like 2 seconds and the external screen went black. WTF. I held down the power, then tapped it for about 2 seconds. After 15 to 20 seconds, I was back into windows on the external monitor. I said screw it, and I just rebooted from the logon screen, I kept hitting the del key and viola! I was in the bios on the external monitor with no hiccups. I hit optimized defaults and reset, saved, rebooted. Then I had the pleasure of seeing the bios screen on both the tablet and the external monitor, and the windows booting screen on both, then windows itself on both screens.

Moral of this story, it might not be dead, try it with a micro hdmi to hdmi adapter, who knows, maybe the bios got borked and maybe it will work again attached to an external monitor.

Also, it took forever for the tablet to fully charge, like the first 5 times. Now mine is running great. It takes a while to charge now, but not nearly as long, its like half as long now, unless I’m using the usb hub I have that also charges. I know its fully charged when the orange light is not blinking anymore when its plugged in. The orange light stays solid when its fully charged. Also, (just a side note) I have to hold the power button down for about 2 seconds for it to turn on.

BTW, the day I got mine, I took it out of the package, hit the power button (for 2 seconds or so) and it turned on, went into windows for about 30 seconds, just enough time for me to click on the battery and it said 32 percent, and then it spontaneously shut off. I hit the power again and nothing. I plugged it in and nothing, no orange light, nothing. I tried a “known good” adapter, and the orange light started blinking and the screen lit up and said 0% battery critically low (I guess that means “no boot into windows”). Because it wouldn’t boot into windows with the battery critically low. I had to wait until it was at like 7% before it would boot into windows. Then I fully charged it, fully discharged it, and did that a few times, just to make sure the stupid battery was calibrated properly. All seems well now, except for a few messups on my part. The new bios released by chuwi, is, in fact 64 bit and will allow you to install windows x64 as well as dual boot android 5.0. Its tricky to get the bios to flash as the current uefi bios is 32 bit, you can research some intel bioses, some have gone from 32bit to 64bit. I’m not going to tell anyone the steps it took, because there is a high probability of bricking the device. Unless you backup the device and have the ability to either jtag or eeprom or pic flash or any other means of using an external flashing device, I wouldn’t bother trying to flash the 64 bit bios over the 32 bit. You may notice that the 64 bit bios is exactly twice the size (giving you an indication that it is so, because it is 64 bit and 64 bit is twice 32 bit), and you may notice if you extract it, put it on the tablet, boot into the efi shell (when on a usb flash drive, from within the bios), then hit “esc” to exit the script (that will fail every time) and try to run “fpt64.efi bios.bin”, after, of course, you mount the usb drive from with the efi shell by typing “fs3:” (or if you have the usb partition or its physically after an sd card or something, using “fs4:), you may notice the efi shell complaining that, it is unable to run 64 bit commands from within an ia32 bit environment. It may dawn on you, suddenly, that flashing this 64 bit bios from within a 32 bit shell, without a proper 32 to 64 bit translation script, will be impossible, or could, possibly be done externally. There are other ways this can be done, through dos, for instance (if you can get it, or freedos to load), but definitely not through 32 bit windows. The actual flashing (if done through software means) is done through the bios, and you have to get through or rather disable, its “secure bios” protection, via a modification of the flashing script. There is a high probability of borking the tablet in any case, as this bios is basically alpha. There will be another non-alpha bios released within the next month or so, after the (now for sale) dual boot version of the hi8 pro has been out for a while and the “engineers” have had a chance to address the problems and issues that will definitely arise from its very recent release (3/25). I think they like to use their consumers as beta testers for most of their devices, judging by all the issues that have come up on all the forums I’ve visited. They seem to release a relatively stable bios for their products about 9 months to a year after it has been sold to the public, that has the majority of the issues resolved and the majority of complaints about it taken care of.
