Have you tried running it through the official Clockworkmod Recovery builder? Or have you taken a look at the guides Porting ClockworkMod Recovery to a New Device and [GUIDE] Compile CWM Recovery?

i have tried porting it. i dont knw if its working or not.because its a MT6577 device and i cannot get it to flash the recovery partiton. even AIO flasher hangs when i try to flash recovery.can u tell me if the below given build is a successfull port.i used the online builder for this.

First you have to figure out which block is the recovery partition this can be found by either typing in terminal emulator or ADB shell "mount" or running a command similar to "cd dev/block/platform/{SoC Name Here for example mmci-omap-hs.0}/by-name" then once in that directory "ls -l" noting the block name of the recovery partition. After you have done that then you can dump the recovery partition to your phone by running the command "dd if={path to recovery partition you obtained earlier from one of the above mentioned commands} of={path to SD Card or output destination}/recovery.img".

The directory should be by-name not by-num. After you are in the correct directory type "ls -l" the recovery partition should be the partition with the "SOS" name listed. If you only have by-num directory you can try running (Make sure to be running the shell as superuser by typing "su" in terminal emulator or ADB shell first) "cat /proc/mtd" and if that doesn't work try (Also with superuser permissions) cat /proc/emmc both of this commands if they return a value the recovery partition will be named "recovery". Let me know if you still have questions .

here is s gscript that lets u dump all the partitions.a ful rom backup.
i have a full dump.only the PRELOADER and DSP_bl is corrupted.
i cant get them to load in sp flash tools
see the attached gscript.for complete backup use the "back_mt6575_a4_v2c" script.
i have attacher the scatter file if some one needs it.my device is still in servicing.so i cant go foreward.
{credits for the "back_mt6575_a4_v2c" script to original developer.i fount it not mine.i dont knw whos it is.}

---

M very noob in all this things and i dnt know how to use above scripts
but from the reply above -1
i got it how to backup recovery img
cat /proc/emmc this command works
learning learning learning will ask question if i stuck
preparing ubuntu pc

---

here is the turorial how to use the gscript.http://forum.xda-developers.com/showthread.php?t=1825722
see the section where it says rombackup.
but instead of using the script mentioned in the tutorial.use the one i have given above.u dont need any commands here.it will backup automatically/.

These are .img files and need to be flashed using Mobile Uncle from Play Store
Once you have downloaded any of the recovery file you need to download the MOBILE UNCLE MTK TOOL on google play store for you to port the recovery update on your phone.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
and then copy the RECOVERY.IMG from the recovery image you have downloaded either the CWMR and TWRP on the root of your sd card or internal storage
now open the MOBILE UNCLE MTK TOOL and click the RECOVERY UPDATE and you will see the RECOVERY.IMG at the top that you have copy on the root of your storage.
NOTE: be sure to check the spelling that it is spelled as “recovery.img” without the quotes or else it will not be detected on the folder
now just click ok then ok again and it will reboot to recovery, after rebooting it will now be on the recovery mode that you have chosen , in this example i used the TWRP v2.3.2.3.
and now you can select backup and check all the things you want to backup and swipe the handle on the bottom part and wait for it to finish
to check if you have backup successfully you can click the restore mode and you will see the backup you have made, and from there you can choose on what backup you want to restore.
ALL THE BEST GUYS!!!!!
