Steps performed.

Installation of Linux

2-      RedBoot> load -r -b 0x01600000 zImage
3-      RedBoot> fis unlock linux
4-      RedBoot> fis erase -f 0x50060000 -l 0x00100000
5-      RedBoot> fis create -f 0x50060000 -l 0x00100000 -e 0x001600000 -r  0x001600000 -s  0x00100000  Linux
6-      Power Recycle the modem.

Root FS recovery:

1-      Download RootFs.bin for infinity Modem (3000 series)
2-      load RootFS.bin -v -b 0x00020000 -r -m tftp -h  192.168.0.2
3-      fis create RootFS -b 0x00020000 -l 0x00E80000 -f 0x50160000 -e 0x01600000 -r 0x50160000

after performing these steps modem still stuck on  Redboot but now we are able to execute linux  by following commands

1-      RedBoot> fis load linux
2-      RedBoot> exec -c "root=/dev/mtdblock2 console=ttyS1,9600 single"

After that Modem is in /# mode

Then i tried to recover the modem by installing  the following packages (linux_2.4_bsp-11.0.3.1.pkg & remote_3XXX-11.0.3.1.pkg ) and download a good known option file through winSCP. But again i stuck on Red boot every time when modem was rebooted or power recycled.

Kindly advise for resolving this problem.
