it looks like cloud credentials are gone (0xff0000). did you make backup before flashing anything with programmer or after?

There is only firmware backed up after the brick T.T
Are you solved your problem? Maybe I can help you.
@cstrassburg Please help I am Having Same Problem
Really the same problem? You wrote the spi chip with a programmer and nothing is working now? Do you have a dump from the flash? A dump before the update? How do you program the chip? Which software, which hardware? Some of the software has problems with some chips. If you get a warning at reading the chip, maybe you read garbage. The best is to read the firmware twice and do a diff.
If the bootloader is working you don't need to program the whole chip. You can update single partitions over a serial connection to the console. Do you have a usb UART adapter?
If you brick the camera with a tf_recovery.img or tf_update.img your BOOT, CONFIG and FACTORY partitions are untouched, because in tf_recovery.img are only KERNEL,ROOTFS and DATA partitions. If you camera is booting and you see messages on the console maybe you can read and flash the chip over the os.
Hi @buttermocca , can you provide MJSXJ02CM ch341a full backup firmware for me? My MJSXJ02CM was bricked...
here you are... 4.0.9 for MJSXJ02CM - tested
I have repaired it 1 month ago, no matter what, I have to thank you~ 😋
what software did you use to make a backup?
If this is question for me - "AS Programmer 2.0.0 something". When I needed to program the chip I had to use "Unsecure->Erase->Write->Verify" and then I had to set Secure bits again. Without Securing chip, camera "died" again on second restart after proper setup.
The reason the backup (and all older) firmware does not work is due to change in firmware formart from version 4.09 onwards. You will only be able to update with firmware newer than 4.09. There is no way to downgrade the firmware, apparantly.

Can anyone check what the problem is?
