Thanks. Will try this too. My experience with QPST is very sad. These images and flashers are somewhat crypted for each device.
I'll report soon. I'm still on the sdcard flash path.

I saw your post here will you please upload those .mbn .hex .bin and all small OEM boot files .

I have original mbn files that come in the fastboot/recovery flashing, update.zip which you might be having or you'll get them from internet here:
http://xdafirmware.com/micromax-a87
Rest all files I'll upload one by one in this post or next. . Those are for MSM7627A, but are device specific as far as I experienced.
The Qpst thing pushed me to this sdcard booting method which I hope works.
Try these files and tell me if they work.

Thanks Yogesh,
is their any progress with sdcard booting, ? Do u succeeded with raw dump ? I assume That is the only way to force the device to boot from sdcard. I am wondering, which file is used at first sector for chainloading rest of boot files, not boot.img probably. Will u examine somehow !

Frankly speaking , no. There is this problem of finding the right partition and the second is that we don't get output from all partitions shown in the moounts. There are many threads which are giving me some hope. Let's see. But I'll come back with whatever success I get.

Hmm...Actually, I am involved with 3 devices with same situation. Samsung gt7562 in CDMA technology mode, A87 and YUREKA in QDLOAD 9008 mode, I asked saurabh k for his old MMX A87.. Once I shall receive that i'll continue for making raw dump of mtd partitions.

Yes gt7562 is gsm, but in CDMA technology mode (I think this is similar to qdload mode with blown Qfuse) not going to download mode, displays only splash screen of Samsung title and model no. Odin recognizes it but whenever tried to flash it stuck at "setup connection".

If you want any files from GT- 7562 just tell me. i'll be returning the cell in a few days time.

Achieved a little success finally !!!

Woops ! It is li'll complicated now....But don't worry, it is not impossible. I'll do something for single Raw Dump.
For now Please upload all partition separately in a zip/rar/tar
i.e
mtdblock0 as boot.img
mtdblok1 as system.img
mtdblock2 as splash.img
mtdblock3 as cache.img
mtdblock4 as persist.img
mtdblock5 as recovery.img
mtdblock6 as misc.img
mtdblock7 as userdata.img
mtdblock8 as msm_nand.img

Code:

dd if=/dev/block/mtdblock0 of=/sdcard/boot.img

And so on....
Thanks for keeping patient.

I finally got the partition dumps. But I tried various methods for it
1. adb shell
su
#dd if=/dev/block/mtdblock0 of=/sdcard/boot.img
#dd if=/dev/block/mtdblock1 of=/sdcard/system.img
and so on.... but it returned the 0+0 read error I/O error. for all partitions.

#chmod 0777 didn't help.
I got my volume buttons repaired and tried dumps from recovery it also gave read errors ....
Then I tried
2. Dump_image.
# dump_image <partition> /(path to save).img , which gave a huge hope as it dumped some partitions, but refused "msm_nand" partition, I tried it from adb shell as well as recovery.
I got success with the following:

3. # cat > /dev/mtd/mtdblock0 /sdcard/boot.img
# cat > /dev/mtd/mtdblock1 /sdcard/system.img ................etc. all partitions

In all 9 partitions,
Boot, System,Splash,Recovery, Misc, Persist, Cache, Userdata, Msm_nand.

Some more methods were there but I don't recollect them as they too failed. I did these procedures with many devices. The methods are not wrong but work with that particular device.
The dd method save one of my friends rockchip device RK2928 Eurostar which I accidently bricked when I deleted some system apks.
If you need those dumps I'll do it.

No news from you for long. Any success with Gt7562 ? And any idea regarding our A87 after these dumps ? Hope you saw my post.
