我的机子是b860av1.1,浙江电信,本来运行得好好的,后来想刷机,又不懂,就在网上(tvapk——net/thread-2325775-1-1.html)下了一个浙江电信的固件,然后把系统文件里面的ota.zip手动替换了,然后使用终端模拟器运行了recovery,然后把系统刷了,之后系统启动时就一直重启,就变砖了。
今天刚到了一根usb转ttl线,想把里面的ota换回来,但是只能进uboot界面,然后我就按照教程znds——com/tv-618487-1-1.html,一步步做,做了SD启动卡,最后一步不行呢,就是进不了rec。但是又看不懂大神所说的分区刷入救砖。过程如下:
第一步,刷入boot
m8m2_n200_v1#sdc_update bootloader u-boot-aml-ucl.bin
sdio_detect return 1
[mmc_init] SDIO Port B:0, if_type=7, initialized OK!

mmc switch part boot1 success
mmc switch part user success
msg:Burn complete
BURN u-boot-aml-ucl.bin to part bootloader OK!
=====>Burn part bootloader in fmt normal OK<======
第二步,刷入rec
m8m2_n200_v1#sdc_update recovery uImage_recovery
Device: SDIO Port B
Manufacturer ID: 0
OEM: 0

msg:Burn complete
BURN uImage_recovery to part recovery OK!
=====>Burn part recovery in fmt normal OK<======
重启后无法进入rec,试了很多次都无法进入
第三步刷入ota时
m8m2_n200_v1#run recovery --update_package=/sdcard/ota.zip
enter recovery
Device: SDIO Port B
Manufacturer ID: 0
OEM: 0
Name: Tran Speed: 20000000
Rd Block Len: 512
SD version 2.0
High Capacity: Yes
Capacity: 7948206080
Boot Part Size: 0
Bus Width: 4-bit
reading recovery.img
** Unable to read "recovery.img" from mmc 0:1 **
Err imgread(L330):Fmt unsupported!genFmt 0x0 != 0x3
no recovery in flash
## Error: "--update_package=/sdcard/ota.zip" not defined
求大神献救砖之策!!!!
