trick to flash rom of a device in recovery bootloop

[AC Question]

I have a sprd device which ran android 2.3.5. It was rooted months back and I had removed some bloatware that time. It was running fine.
I rooted it again today to allow Titanium backup(TB) to run "su" properly.
From one post I read that deleting live wallpaper will not harm system, and I tried that. TB told me that it will modify the recovery image and reboot the system twice to remove the app. I allowed it to do so.

Now the system is in a boot loop, with upto an icon(may be specific to TB) after the manufacturer logo.

I have tried the (Vol-)+Power key combination which does not work. I too have installed adb afterwards to issue the command
#adb reboot recovery . But this command does not find the device listed. The adb devices also does not find any.

I can flash the rom, or firmware or anything else provided I am properly guided.

How you flash a ROM depends on the make and model of the device. Tell us that and someone can point you to reflash instructions for that device.
