Problem Lumia 710- Can't flash with recovery or refurbish.

I had on the phone 1600.3013.8107.11502. Then I update to 1600.3015.8107.12070. I did it by the refurbish option in the NCS. One month later i wanted to flash on 1600.3030.8773.12120
When i plug phone, the computer detected it other than ever. I saw Qualcomm CDMA Technologies MSM and removable disk with question about formatting. I clicked cancel but NCS does not detect the phone. My computer couldn't install driver for Qualcomm CDMA Technologies MSM. I tried it on others computers but on all its the same, i can't flash this ****. I was looing for solution on others forums but no one can help with this.
Thx for answers.
You have the Qualcomm bootloader. NCS does not recognize this bootloader. I f you want NCS to recognize your device, you will need the NOKIA DLOAD bootloader. However, the Qualcomm is the unlocked one, so depending on your preferences, you can leave it on the Qualcomm. With the unlocked bootloader (which you have) you will only need an other flashing method. Those can be found on the forums here.

If you have this error, please check if the phone restarts in this step or just
stays in Normal mode (windows screen). There are some software versions that
will not respond to the OSBL change command. So just try to flash different
version (via .nb file) and try again.
The other option is the manual restore(hex edit), but its really risky if you don't know
what are you doing.
The problem seems to be caused by version mismatch between the OS and the
baseband firmware. Here the solution and more info.
I also has a problem like: "Are you sure you have development Qcom loader"
when trying to flash rainbow mod FW by lucifer to my lumia 710 using NSS pro v0.48. Does anyone has a same problem with me? all steps that told in http://forum.xda-developers.com/showthread.php?t=1620629 i already been followed. but still i can't flash the FW mod, FYI I already succeed in installing FW with qualcom bootloader before using NSS pro.

sim-unlocking Lumia 710

Hi all, I think it would be possible to sim-unlock a Lumia rewriting all the partition ( 9 in all ) with the same from an unlocked Lumia ( possibly never unlocked .... ). With the dd linux command could be simple. What do you think ?
is there anyone that could post the whole 9 partitions from a Lumia 710 ?

Hi Leoman, see this thread HERE.
Cheerz,
Done but with problems. I overwrited eight partitions except the fifth, that contains the telephone data as serial number and other stuffs ( but I didn't find in it the IMEI ). Befor turning on the phone I restored the firmware ( unlocked ) trying to totally restore all the partions that could retain data not coming from my firmware. The telephone boots fine and it no more calls for the unlock code but is says "no service". Apparently I stucked the radio software. Having the qualcomm bootloader I tried to restore the NOKIA DLOAD as described in this post
http://forum.xda-developers.com/showthread.php?t=1702815
to restore the original firmware but, surprise, NCS can't no more flashing the firmware. It says that there is a problem with OSBL. I tried with other firmware without no success. I tried with windows recovery phone tools but it says that cannot restore the telephone .... I read that at least another had the same problem restoring the nokia dload with the above procedure ...

You can use NSS 0.47 (or 0.48) to easily restore the Nokia Dload. Check here http://forum.xda-developers.com/showthread.php?t=1620629

[Q] Lumia 800 + Qualcomm + NCS

Hi guys,
I've been trying to update my Lumia 800 (RM-801, detects as RM-819, Qualcomm bootloader) using Nokia Care Suite. I've tried just about everything that I can think of and still I cannot get this useless bit of software to go past the "lost connection" screen. Just to ensure clarity, I am on Qualcomm's bootloader (NOT DLOAD) and have tried on both Win8 x64 and Win7 x86 with no luck anywhere. I don't care if I have to lose the QC bootloader to do this, I'm done with custom ROMs anyway. Can someone shed any light on why NCS stubbornly refuses to work on my phone?
Thanks.
You need to use QPST instead of NCS for Qualcomm-bootloader phones.
