"Cloned" A50 blinking backlight problem - GSM-Forum

AssenBG · 12-20-2002, 01:44

As You know, there is possibility to modify hardware of A50 to becoma "cloned" C45. In some variants of PCB, power management ASIC is Dialog, in other it's ST. In these PCBs (with ST) there is blinking backlight problem.
We are proud to say that we have solution for this problem.

That's a clever boy !
we are amazing!
really hero...

yes you can modify.......

Calculate CRC

Best regards

Dear friends, I would like to say that this is not a software problem at all. Calculating CRCs not help. This is just a hardware problem
Merry Christmas!

so ,will you tell us what(where) is the problem?

debeliamark · 12-24-2002, 06:47

The problem is in ST power IC (also in eeprom i BA20 flash IC - you must rewrite all flash - boot eeprom and firmware - but it's not easy with Unisiemens) - friend from BG - just send your f.... ed phones to AssenBG

For the decision blinking backlight problem establish the resistor 33kOm as is shown :-)

To vladwork1974:

Hello,
and what we must to do after installing resistors?

vladwork1974 · 01-05-2003, 07:39

If you already have made "C45" from A50 at you will be blinking backlight problem. So the resistor ( 33kOm :-)) removes this problem. Only occurs new problem....:-))) Current of consumption of the telephone to increase twice
Contact to me ICQ 41247951 or mail

vladwork1974 · 01-05-2003, 08:09

Probably who has found solution blinking backlight problem without damage of a current of consumption?
Is probably necessary association of parts firmware A50&C45?
:-))
