Hi, I'm testing with a BLACKPHONE BP1 phone, this device has an NVIDIA processor, model TEGRA 4i.

The phone I put in APX mode, with the drivers well configured on my pc, then with the program nvflash I send the following command …

nvflash.exe –bct ../common_bct.cfg –bl ../bootloader.bin –go
nvflash.exe -r –read 4 ROM / bootloader.bin
nvflash.exe -r –read 6 ROM / bootlogo.bmp
nvflash.exe -r –read 7 ROM / lowbat.bmp
nvflash.exe -r –read 8 ROM / charging.bmp
nvflash.exe -r –read 9 ROM / lowbatcharge.bmp
nvflash.exe -r –read 11 ROM / tos.img
nvflash.exe -r –read 12 ROM / eks.dat
nvflash.exe -r –read 15 ROM / recovery.img
nvflash.exe -r –read 16 ROM / tegra148-ceres.dtb
nvflash.exe -r –read 17 ROM / boot.img
nvflash.exe -r –read 18 ROM / system.img
nvflash.exe -r –read 19 ROM / cache.img
nvflash.exe -r –read 23 ROM / MDM.img
nvflash.exe -r –read 24 ROM / log.img
nvflash.exe -r –read 26 ROM / userdata.img

and it only comes out …

Nvflash 4.10.1800 started
chip uid from BR is 0x61401001740970812000000017fb86c0

I need help to know what the error is.
A greetings greeting.

It's not that simple. In fact, Tegra based devices were always a problem, even to recover from APX mode.

To actually use APX mode you need a special blob file that's unique for each device. It authorizes the connection and then allows you to use nvflash. Here's how it looked on Nexus 7 2012 with Tegra 3. The main problem is getting that blob file.
