Flashing A780 to .76AP

[Ajeevlal]

Hey all,

I am abt to upgrade my phone to .76 AP and i am new to flashing and need some help from you guys.... From this posts i have learnt many of the people tried to flash the phone and ended in damaging the phone. My current FW is

R52_G_0D.50.AEP
BP:R52_G_0D.39.B1P
BPFlex: GCOA780000SA061
DSP:62252500
Technology Quad-Band GSM

I have searched this forum and learnt that to upgrade to .76 AP i have to follow the below upgrade process

1st - R52_G_0D.50.AHP_0D.42.B1P (latest BP)
2nd - R52_G_0D.61.A1R (transition)
3rd - R52_G_0D.74.A2R (to be safe)
4th - R52_G_0D.76.A2 (latest AP)

So downloaded the below files

1st - R52_G_0D.50.AHP_0D.42.B1P_T673AS_L001_S018_P003_GSOA780T673AS064_1ff.shx
2nd - R52_G_0D.61.A1R_Transition
3rd - R52_G_0D.74.A2R_0D.C0.B1P_SE6820AD3F1_L003_S008_P004_GCOA780000E1025_full
4th - R52G0D.76.A1R0D.C0.B1PSE6820AD3F1L001S010P004GCOA780000E1027full

Please let me know whether these versions are the correct one and am i following the correct process?. Also i will appreciate if any one of you can me give link for flashing process. Thanks in advance..................

I already have done so, thats why i am 100% confident

I did that and now the phone is dead and still fail to flash....and now can't even turn it into bootloader mode or turn it on....even try a fully charged battery, still nothing....and the file I downloaded is from this site...so now i don't know what the hell.....any help on this???....gonna try to flash it back to 50, if it still won't turn on then I guess I'm just gonna have to take it to the service center and let them do it....but still appreciate any help/comment on the situation.....

atlast i tried to flash my phone.... to start with i tried the .61 transition but it failed so i tired back to my old R52_G_0D.50.AEP_0D.39.B1P but it failed during flashing now i cannot even power on my phone.... any one please help

i fully charged my phone before flashing and the batterly is a new one (so the problem should not be with battery)

Now i was able to power up the phone using boot mode and now i tried to install .61 transistion.

This is what the upgrade step documentation states
