Tolino Vision bricked?

[hk4fun]

hi,
I got a Tolino Visio which is stuck at the Tolino logo. I can boot intro recovery but I cannot wipe and/or recovery the system, is failing with:

E:failed to verify whole-file signature
E:signature verification failed

I was able to connect to serial port and see the u-boot. I've attached the startup log from u-boot.

Any idea what I can do to restore it from SD card or from u-boot? One idea is to use some Kobo Aura tutorials to try to boot the os from external SD card, but no idea if it will work, and which image to restore on the card, and where to get them.




u-boot.txt

I've tired to boot intro fastboot but I am getting unrecognised device under windows. If I put it in download_mode under u-boot, the usb is recognised as Freescale. Any other ideas what to try?

I was able to use fastboot:

1. connect over UART to computer and stop boot sequence by pressing enter until you see:
eBR-1A #
2. type download_mode
this will put the device in download mode and it will be recognised by computer as Freescale i.MX6
3. clone and compile https://github.com/boundarydevices/imx_usb_loader
4. download the correct version of u-boot from tolino website https://opensource.mytolino.com/open...tolino-vision/
5. after compilation of imx_usb_loader run:
sudo ./imx_usb u-boot.bin
open another terminal and prepare to send this command and another terminal with UART connection
6. after you send the new u-boot will boot there so prepare to stop the boot process from UART
7. run command fastboot
now you are in fastboot

from this point I was able to load twrp. So I am close to bring my Vision back to life.

After fastboot download the restore image from here. My tolino vision is restore and is works.

step 2
after download_mode command, uart response with reseting... and nothing
I have a similar problem as you, after the update the file remained on my memory and device is bootlooped

any advice would be great

Moingiorno,

I'm a bit desperate and grateful for any help or ideas.

My Vision 6 suddenly wouldn't turn on, but recovered after I connected it to a Windows 11 laptop. I was then able to install the KOreader without root. For about a week it has hardly responded and I had to wait forever for a book to open.

tolino does not respond. [Exit] [Wait]

So booted into recovery without success, when I then wanted to install the update.zip via OpenMTP, copying failed and in the (factory) recovery always came up

failed to format /cache

I successfully wrote v6-15.3.0-16gb-root-m23016.img to a new microSD, the old one could not even be cloned. Now the Vision no longer responds at all, but is recognized as an unknown device in Windows. Charging no longer works either, just testing the original cable and power supply. I'm afraid it's dead, please help me.

Thank you.

Clean the SD slot and somewhere there is a 64GB image at allesebook.de

Thanks so much, blowing out the slot with compressed air worked. I also found a 64 and a 32 GB image on allesebook, but unfortunately balenaetcher shows the image as to big 31.9 for the SDs (tried 2 already) being 31.7 gigs…

There is no problem with a 32 GB image and a 64 GB card.
