Startup error: map: cannot find required map name

[jmc]

Okay, strangely enough now I just pressed the power button for a long time so the device actually shut down… and it turned on normally. So if anyone has this problem just try this.

Was your battery low? Sometimes I got that message or similar on the X98 Air 3G when the battery was low.

That’s not the case, it was connected to the charger then.

I read the board a bit and I have to say that my Chuwi also has a problem with randomly turing off – it happens sometimes in sleep mode. And this is when the problem occured – I switched to sleep mode, the device turned off for whatever reason and I got the “cannot find required map name” error when i turned it on the next day. Also, it was after I inserted a microSD card for the first time, but it might be just a coincidence.

Anyway, it works perfectly fine for now.

Hi jmc!

I have the same problem. I was contacting with the seller of the tablet (for me geekbuying.com) and they said that it’s needed to reflash the BIOS. It’s look like that it’s doesn’t find the eMMC. Sometimes the Windows Boot Manager shows up in BIOS sometimes not. I’m now trying to download the files. If it’s help, i will post the instructions.

If you have something new  then please post 😀

PS.:Sorry for my English…

Hi!

I downloaded the new V300 bios (607) and now it’s working fine! I never seen again the ugly EFI Shell!! 😀 Try it if you haven’t got yet other solution! 🙂

@hahn are you able to post a step by step guide to updating bios please. I have same issue where it randomly boots to efi shell prompt.

Hi!

Use at your own risk. I’m not responsible for any damage this method may do to your tablet.

So the guide:

Charge full the tablet! Then you can leave it on the charger if you want! Dont turn it off when its flash the bios! Read the other topics about bios flashing!

First you need to decide if the serial number higher than 42151103000 than its okay<strong>. </strong>If its smaller then you need other files.

There is an other forum topic Chuwi H10 32to64bit upgrade v200 hardware. There is the first post is Przemo`s post about the files. Head over to the Google drive link and download the P02-C106_B101UAN_607_RealTek_wifi_20151224.zip file.

When you unzip it you will see some files and an other zip file. <strong>So now you will flash the bios!!! </strong>You have 2 options: unzip the P02-C106_B101UAN_607_RealTek_wifi_20151224.zip file and put it on a USB flash drive. When the tablet start booting you can press F7 to get the boot menu or go to the bios and set the boot order to boot from your flash drive. Then it will boot from it and it will flash the bios <strong>or</strong> if you can get the tablet to Windows then unzip the zip file inside the P02-C106_B101UAN_607_RealTek_wifi_20151224.zip file and run the flashing program. <strong>WARNING!!! I repeat that it will flash your bios! Dont turn it off when its flashing! 

After that may you need to set back the boot order to boot from Windows Boot Manager. Now, if everything is good, it will boot to windows.

If you screwd something then you may will have a new cutting board or may you can repair it. For more info read the ChuwiH10 32to64bit upgrade v200 hardware topic.

I hope that everybody can understand it.

Greetings from Hungary!
