blackberry 9900 dead any solution

[sineesh]

crystal oscillator power ic all change same condition

[7phone]

if all the voltage appears, but still dead,,,what steps should be done?? Any solutions master???

the last step very very very Dangerous over heat kill your phone,after that "FULLSTOP"(dead end)due to CPU

Change Cpu crystal(Oscillator) X1101.

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

Sorry for bad english.

I love you Munir! I can confirm that replacing the crystal oscillator works!

While it works with 9900's that don't power on but show the red light it doesn't seem to resolve the 9900's with the 3 fast blinking lights. Do you have a solution for this Munir?

pls..indicated type of red blink in 1 & 0 order as per jpg.(Example 1101 or 10111 etc..)

which crystal oscillator you had replaced 1.near power IC or 2.near CPU?

[loomingx]

near power ic. I've fixed 3 devices so far. All devices would flash a solid red for a few seconds, go away and then come back. The devices that I am still unable to think are the flashing red lights (3 or 4 blinks). I have tried replacing the oscillator by the power ic on these devices and same symptoms. Do you suggest replacing the oscillator by the CPU or is it more likely the power ic or smaller ics under the emi heat sheilds to the left that sometimes need to be replaced.

1.In dead phone only you need to refresh or replace crystal oscillator.not for red light when crystal oscillator is ok their after it give red light or goes into booting.
2.In your solid red for a few seconds case insert charger without battery & wait after red light it's show no battery symbol in display than 1. change touchscreen, It's most important at booting time that if mobile can't sense touchscreen than it will reboot again frequently.2.check two line most important I2C_SCL_AUX & I2C_SDA_AUX. It's used in many section for that reffer schematic and replace those thing and put it again If you will not put it again than it's gives new problem like hang or reboot after sometime.

The ones that I was able to fix showed a solid red for a few seconds, went away for 5-10 seconds and then come back in a constant loop. replacing the crystal oscillator solved this issue. The devices that I have and can not fix flash the red light 3 or 4 times quickly. I have already tried replacing the touchscreen, complete screen assembly, reloading the software through BB Desktop Manager, App loader, and other 3rd party programs. If it is not a part, the software, or the crystal oscillator what is the most likely component that needs to be replaced?

I'm sorry but I don't know what you mean by: I2C_SCL_AUX & I2C_SDA_AUX

Dear bro try to understood my post carefully. I had given complete explanation.I can't understand your "red light 3 or 4 times quickly" explanation.I only understand 10111 red light code, so give in that form only.two line most important I2C_SCL_AUX & I2C_SDA_AUX for that you had to go through schematic for this two line you have to work hard on schematic.It's used in many section for that reffer schematic and replace those thing and put it again If you will not put it again than it's gives new problem like hang or reboot after sometime.

What if I can't find another crtystal oscillator, can I make jumper on oscillator?

Or is there any phone that sharez the same crystal............?

[avesunlock]

please any body with the solution for 9900 and 9930 always restart unless i plug charger before i can used the phone, immediately i removed charger phone shut down instant.
any solution to it please.
