Lightbulb 3310's almost dead but not completely SOS!


hi guys,

i have here 4x3310 with different faults...one was made by me

number 1.

cant switch on but when chagred connected battery bar flashing and not charging if you will try to power it on all LEds just flashing on you while you hold the button but nothing...without charger cant switch it on at all.seems like no water damage.

i tried to flash eeprom just to c what will happen but its starting to erase and coming up with error Low battery - this is with charger plugged in without charger...DEAD

number 2.

cant power it on but NU2000 says "Error wrong type or the phone"(or something)...where i clearly have 3310...cant switch it on or chrage...

number 3.

MY stupid mistake...phone was fine but freezing and rebooting itself afterwoods...i removed L511 thinking it will help...now i cant power it on...will try to solder it back later...but not sure what to do next if it will come back to normal state...

number 4.

had that phone for ages...no signal...everything else fine...

guys need help with these phones...who can help plz help!

and last question...where i can buy parts like PA's,CCONT's etc...coz i have a lot of other phones around like 6210's with no power etc...

equipment im using: HotAirStation850,Mbus/Fbus,thing which washes out those water damaged phones(dont know the name por it) and brains(if any)

cheers

Re: 3310's almost dead but not completely SOS!

no.1.
Looks like MAD problem. Or maybe CCONT? Try to change CCONT first, than replace MAD.

no.2.
Try to full flash it with image form good phone, after thar recalculate FAID.

no.3.
Removing L511 wont kill your phone. You have some other problem with this one.

no.4.
No signal at all, or you have signal for 3-5 secs when turn it on?

1
Reflow CCONT with flux. Don't try to reflow MAD because it is glued to PCB. Removing MAD is very difficult, try to find some broken boards to practice.

2
First be sure that it is 3310 and not 3330.
Don't just write MCU+PPM. Take a good phone and read full flash with Rolis (2MB). Then write whole flash to your no.2. After that recalculate FAID and change IMEI to original one.

3
Strange problem. Try to change 26 MHz crystal

4
PA, 99% or antenna switch. Try to change PA first.

5
Go to sleep. It's late, do steps 1-4 tommorow in the morning

Hi hulala.!

1. Try change CCONT, and reball or change cobba and after try the full flash.

2. I think just the same

3. I think It isn't the L511 fault....

4. Try a full flash and update faid!

Good Luck!

B.R.

about reballing

it is like resoldering.
You remove BGA IC, clean it, clean the board, make new solder balls and resolder it to place.
