Upload bloked at 4% - Wrong firmware?

[burgman73]

Hello everyone, can you help me understand what firmware to put on this device? I do not know the brand but I know that it mounts a s905x, 2gbram and 8gb of rom. Initially it was installed on Android 7.1.1, then after a voltage drop (or a peak) it is no longer possible to load Android with USB burning tools as the upload stops at 4%. However it starts without problems from external sd with libreelec. I feared it was a burnt flash problem and I tried to replace it but even with the new flash it always stopped at 4%. I think it mounts a type of flash that is not recognized.

Cheers

Hello, that welding was there even before I tried to replace the flash. In the flash database one of those pins is "NC" while the other and the VCC. So unused but could be used to join two tracks on the PCB. To put the device in writing of the flash, power must be given by holding down the reset button and he will restart to upload the USB cable. I could try to remove that short but I would not want it to stop altogether. Have you ever seen a solution like this?
