Make the TestPoint Of SX1

乞丐BB仔

一直在寻求make the Testpoint of SX1的方法，than Freia V15  can read Flull Flash from SX1 and save to a bin file.
为此，我向德国的一些高手学习了一下。
[em04]How to make the testpoint ? Solder a resistance beside the IC PMB 7850 E ? how much ohm of the resistance ?

[em05]first of all, you don't have to place resistor, you have to REMOVE it as shown on many pictures (with arrow pointing to what resistor has to be removed).
second, not all phones have that resistor therefore not capable of utilising this trick. most of officially sold in the shops phones are different PCB design. for them you have to unsolder CPU, remove T9 ball and solder CPU back. it is very difficult and time consuming process, you need to have proper tools, such as hot air gun, tweesers, balls (for resoldering BGA processor). Why do you NEED to read/write fullflash?
[em04]Thank you.
My mainboard have not the resistor that you said.
Is the cpu that you said Infineon PMB 7850 E or omap(TM) 310?
what and where is the T9 ball ? I have all proper tools that you said .
I want to Read/write the purity fullflash of chinese edition not the other language edition.

I don't make the testpoint,in Fraia V15, The output information:

FREIA - Engine build 15, Frontend build 11
Thanks goes out for the following:
Maxim, Rolis, Sergey, PapaJoe, Lead,
TheWizard, Jozso (for hardware and cable
support and of course beta testing),
Nico, Pinker, Tom, Crew
and all the others who supports ...
COMM_LoadBoots : selected phone family is 16
TTY_OpenCOMPort : opening Prodigy
COMM_IsBootRunning : bootcode does not seem to be running
COMM_LoadBoots : Waiting to power on the phone ...
COMM_LoadBoots : phone is powered on
COMM_SendBoot : boot file is not accepted
[em05]With English at me it is weak, so excuse, if not it is competent!
Now Siemens lets out(releases) 3 kinds of payments sx1, On a payment of the first kind it was necessary to remove the resistor, on a payment of the second kind to remove the processor to remove tin balls and to solder the processor, on payments of the third kind it is necessary to cut something, on the processor too it is necessary To solder. And then to solder in on a place. All this is told by masters and for reliability I do not warrant(I vouch)! All this work very complex(difficult). Its(her) performance needs station, cliches, experience and " direct hands ". Now the most important: FullFlash sx1 completely not such as at usual cellular telephones and we a little that we can change in phone changing the data fullflash unless to disconnect and include illumination клавишь (I yet have not found entri point), moreover a pair of functions. As I understand now the main thing "to count" disk Z that it was possible to change even рингтоны, *.mbm and many other things not to stitch anew phone, and application of patches. Certainly, backup fullflash will not prevent, it is possible to unblock easily always phone not resorting to mastercod. Once again I am sorry for clumsy language, but I think an idea to understand it is possible. Successes.

1.有上图的电阻的，要把电阻焊掉。（但有些板是出厂的时候就没有的，放在市场上的SX1底板有几款的，我的就没有那个电阻的。）
2.要把CPU （是310那块，7850那块是电源IC来的）焊出来，把T9那个锡点弄掉再回焊到板里。
3.用Freia V15即可对SX1进行读写字库，解锁，做MAP等等。
