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.
I tried to restore nokia dload bootloader with NSS Beta but this program says my phone dosn't have qualcomm loader...
Looking for phone...Done.
Device: RM-803-NOKIA Lumia 710
Battery status: 91%
Changing phone mode...Done.
Looking for NAND disk...Not found.
Are you sure you have development Qcom loader ?

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.
Cheers
I was recently given an LG Optimus L9 P769BK and decided to try and unlock the bootloader and root it. Most of the guides (such as: http://forum.xda-developers.com/showthread.php?t=2584997) suggest flashing to V10G_00 first before flashing to the EU V20B_00. I was able to flash to V10G (from V20H that was already on the phone using "LG Flash Tool 2014") but now, no matter what tool I use, I am unable to get ANY ROM to flash to the phone.
Methods/Tools used and the results:
1)http://forum.xda-developers.com/showthread.php?t=2085344
1a)Result: The software that is launched in Step 10 crashes before doing any updating
2)http://forum.xda-developers.com/optimus-l9/general/p765-unbrick-using-lg-flash-tool-2014-t2950433
2a) Using CDMA + Diag or Emergency: Goes to 10% of SW Update then fails with an error saying to remove the battery and try again. Doing this does not resolve the problem
2b) Using 3GQCT + Diag or Emergency: Can not connect to phone. Reseating the connection and power cycling the phone does not resolve this.
3) http://forum.xda-developers.com/showthread.php?t=2748384
3a)Using the LGP769_20121004_LGFLASHv1350.dll and a bin from V20B_00 it freezes around 570 seconds with a write error. The phone no longer boots outside of SW Update Mode.
The phone will now only boot into SW Update mode.
System:
OS: Windows 8.1 64bit
Drivers: LGUnitedMobileDriver_S52MAN314AP22_ML_WHQL_Ver_3.14.1
Any thoughts on what to do next?
UPDATE: The LG Flash Tool mentioned in 3) no longer sees the phone. After following the steps mentioned in the guide again
UPDATE2: Reinstalled the drivers. Method 1) still crashes, 2) same results, 3) still not "seeing" the phone when connected.
UPDATE3: (using Win 7 machine). Method 2) gives an odd "Can not connect to server error" when tried. Method 3) gives a write error on "Failed to Write OMAP" (ill get the exact line in a minute)
UPDATE4: Ignoring the error (aka NOT clicking the box) from Method 2) allowed the phone to flash with no problem
Only the very first v10a had an unlockable bootloader. And the first couple of v20ies or all of them. I unlocked and rooted with v20c, later versions could have locked Bls.
My phone actually has an encrypted bootloader so no ROM will work
I have no soldering skills so I ordered a 910k cable and will do the unlock with it.
Hi guys !
I'm currently trying to unbrick my F600L in bootloop since I tried to downgrade from 20q update.
I founded out later that the V10 has anti rollback feature but it was too late.
Now i'm looking for a kdz or anything flashable to restore my system...
By the way I always get a " invalid command response" error with LGUP while flashing "system" do someone know how to fix it ?
I tried to reset it with LG Bridge but il always fails because the detected software version is the 20q which is the latest... Is there a way to force the restore or update with LG Bridge ?
I tried recovery error fix too but it doesn't find any error...
software update (korean version) stuck at 21%
I have the same problem here. I tried to get back to LL Firmware F600L20n while my phone was on Firmware F600L20q. I used LGUP but it always got stuck at 21% percent on PC and 13 % on LG V10 F600L. And it also showed error codes 0x2000 invallid command. Please help.

to get to bootloader we need to downgrade our phones to Nougat and I've been searching and cannot find a file to flash using lgup to downgrade.
