[Rhamses]

Question:Why to replace the parts?I tried replacing the 6220 HF out with the regular HF out like on 7210/6610 and I saw no difference.I left the old antenna switch and the phone works fine.
But the PM looks like a nice job!
Salut!

At all no need to change RX filter, just antena switch, add first GSM amplifier /and some parts arround his circuit/ and change GSM TX filter ...

P.S. There important is "mixing" of 6200 6220 and 72/6610 PM-s to achieve speaker sound, low RF PA consumption and good network reception ...

[debeliamark]

And also one more - if someone haven't success with BoOzer's pm - try one attached from me

You have really done a great job here. I think more improvement can be done on this experiment.

[abbeydguru]

And also one more - if someone haven't success with BoOzer's pm - try one attached from me

M8, you got to consider the spectrum of the network(1900 or 900\1800, the problem of this experiment is the failure of network after booting.

[abbeydguru]

[haiminhk15_sc]

Hi everybody

It is very easy, don't have anything talk about so much. All band is change to your wish, no problem

All of them, a some model, it's the most important, u must be change logic circuit in order to flash phone is power on :D

Ex: 3595 or 6010, u want convert to 3510i, many phone you must be replace flash IC. After u can possible flash 3510i FW into the phone :D

3595 or 6010 is three type. all of them i even can resolve it .... is OKE. in Vietnam. I already converted it a lot of them in order to use 900Mhz. And behind I solved successfull

1. Don't change anything logic circuit, u need only change two filter RX and TX 900Mhz, Flash IC is AMD flash which same 8310 flash IC ( ID Flash: N643GT7MI )and Flash 3510i FW into the phone, after write PM
2. Flash IC is AMD flash which same 8310 flash IC, but it's different ID Flash ( N643HT7MI ), u must replace Flash IC ( ex: replace Flash which ID flash show N643GT7MI ), after do it same the first case
3. Flash IC is AMD flash which same 3120 flash IC ( Board don't have RAM ), How 're u already must be know ... do it ? :D

All of them I don't lost money, because I can substitute Flash IC between two nokia model ( 3595, 6010 <----> 6610 or 3595, 6010 <----> 3120 )



All nokia model. I can convert band to my wish, If I can resolve logic circuit is good

Do everyone can change band 6620 in order to working on 900Mhz ? :D


Good Luck

[NobrakeS]

Guys, please help me. I am not sure that I got 6200 here. Actually it is 6610 with a weird IMEI startinmg with 010200...... It was absolutely dead. After changing UEM and Flash IC, it was back to life BUT no earphone/speaker/mic at 1800 Mhz.

Should I change those components shown at the pic?

Thank you.
