Hey all,

just posting a fix for support tools getting stuck at 49% and failing. as iv seen a lot of it but no answers

anyway i found this to be the only thing i could get to work on my D802T
I followed the KDZ method in this guide (thanks hyelton)

i got the correct KDZ for my phone from here: http://lg-phone-firmware.com/index.php?id_mod=36

Not sure if it has to be done but others said it helped but that is to Disable OR uninstall the LGE Modem from Device manager and set your phone to Port41

1: Put your phone in download mode by holding the Vol + and pluging in
2: Now in the select type Drop down box choose "CDMA"
3: set phone mode to "EMERGANCY_CS"
4: Select your KDZ file
5: Select "CSE Web Upgrade Test"
6: Click "Upgrade Start"

Now you should see it pass 49% this time, atleast i did

I have helped members with this method. Once this has flashed you will be taken into engineer mode, took me a few minutes how to work out to get out of engineer mode, maybe useful to add to topic.

I bricked my phone trying to flash cloudyG2 3.3 and I've been trying for more than 16 hours to unbrick using stock rom. I can tell you I'm not new to flashing yet I've searched all over the net and none of the proposed solutions worked.
However, after almost giving up on my beautiful monster, LG G2, I came across your post. I tried it and got instant results! The entire operation took me less than 5mins and
my phone was back online!
Thank you for highlighting the switch from Diag to emergency_cs.
I don't know how else to thank you.

THANK YOU!!!!!
