In your 9900 VREG_S3_1P8 volt is drain more current in any section. For that goto this post.

the last chance. No any more step or way.
I hope your phone will be "get well soon".

Sorry for bad english.

Hello Bro. Munir, I want to thank you specially for you contribution to my experience in not only 9900 power issues but in blackberry mobiles in general...
One final question i will want to ask to clear my imagination is, When you say "FULLSTOP"(dead end), Can't the POP Chip ( Cpu and Combo Chip) be replaced, I mean Remove epoxy glue and chips from other board to boards with faulty Cpu or Combo?.
Will an Infra Station do a perfect refurbishing job in removing the epoxy glued Pop Chip in 9900?...

It's possible with infra station.
But before proceed you have good information of CPU and POP flash chip’s temperature.
How much it’s bear. If you over temper than it’s becomes useless.
Now guess how much temperature you need to remove hard epoxy glued of Pop flash than epoxy glued of CPU, CPU heat up twice here it’s dangerous for CPU.
In CPU there are some sensitive I/O (in/out) gates. There are major chances to get fail those line or gates.
When you use an Infra Station the melting point temperature of solder spread all over area where it’s attached include both CPU and POP flash IC. Blackberry use hard PCB material, so its need more temperature to released solder.
If you have new fresh CPU and POP flash IC than you can do it.

according to my post http://forum.gsmhosting.com/vbb/f733...3/#post9966413 all voltages are most important.
If it's zero than first check shorting of those point.If ok than change MAIN POWER U-1201 ic.
VSYS is internal vbat 3.6v if not getting than change JET POWER U1303.
