This is the critical moment. You need to interrupt the boot process to access the U-Boot environment. As soon as the logs start, rapidly press a key combination (usually Enter, Space, or a specific key indicated in the log like 's' or 'a').
If successful, you will be dropped into a command prompt, usually starting with hisilicon # or zte #.
The first boot takes longer than usual (up to 5 minutes) as the cache rebuilds. Zte Zxv10 B760hs2 Custom Firmware
Troubleshooting:
Creating custom firmware for the B760HS2 is not a point-and-click affair. It generally requires one of three hardware-level access methods: This is the critical moment
Of these, UART is the most reliable but requires soldering skills. USB Burning Tool is more user-friendly but requires a compatible Windows PC and the correct license file (often leaked online).
The "B760HS2" label encompasses multiple internal hardware revisions. A firmware that works on a board labeled "V1.0" may brick a board labeled "V2.1" due to differences in: Of these, UART is the most reliable but
Once the file is loaded into memory (RAM), you must write it to the internal NAND flash storage. The command varies based on the partition layout, but it generally looks like:
nand write 0x44000000 0x00000000 [filesize]
Note: The memory addresses and commands above are generalized examples. You must refer to a specific guide for your exact board revision, as writing to the wrong address corrupts the bootloader permanently.
If the write succeeds, you type boot or reset the device.
If your box is completely dead (no LED, no USB detection):
