ROMManager and ClockworkMod Recovery is created by Koush which also CyanogenMod team.Thanks goes to him and CyanogenMod Teams.
This recovery enable us to backup our ROM and restore it if something went wrong with your ROM.
For example if you're trying somebody custom rom and suddenly it won't boot or you get semi-bricked..you could boot into recovery and perform restore within the recovery..given that you've already backup before.
example booting into recovery for MI700:
Press and hold both volume key then press power button
(VOL -) + (VOL +) then press (POWER)
In this guide I will show how to install a non-official ClockworkMod recovery which I have created, within ROMManager.
This guide are meant for CSL Spice MI700 and its variants, such as Commtiva Link N700, Camangi FM600, OlivePad VT-100, Cherry Mobile Superion, Viewpad 7, etc..but may be used as references for any others device.
Rooted devices only, use SuperOneClick v1.5 or Visionanary.apk from Paul..or etc
1.Open Market application and search for ROMManager and install it.
2.Once installed, run the app and tap on "Flash ClockworkMod Recovery"
3.There will be a list of devices shown in the pop-up, in our case choose "Spice MI700, Commtiva Link N700 and more"
4.There will be an error after you choose Spice MI700, as the official recovery is not available, just scroll down and choose "Flash Alternate Recovery"
5.A pop-up will appear "Flash Alternate Recovery" select "OK", Superuser may request for your permission, choose "Allow" then you will see download progress on top..wait until its finished downloading..and flashed the recovery..select "OK".
7.Then choose "Backup Current ROM" from the list..you could rename or use the default date naming..it will reboot your device into recovery mode and perform backup and will reboot back once it has finished performing backup and save it in your sdcard directory.
8.In Recovery Mode..Press and hold the volume button will move it a single line and if the line it goes is what you want to select just press the power button to enter, if you release the volume button it will go to another line, this is because both volume up and down registering double input upon pressing it.
