About reading eeprom of R200 by cable.

[Bogi]

Hi to all.I found these pins:<br />keyboard up,left to right<br />7 - power of eeprom +3V - probably for processor<br />8 - GND<br />12 - SDA <br />13 - SCL<br />You can`t read eeprom of R200 with usual soft for eeprom reading,because eeprom is adressed with pins 1 and 2 conected to +5V.

try to read it WITHOUT battery!<br />And for Vcc use V under<br />2.4V (if you use over - you will power on MCU and will cannot read eeprom).

That's all.

Try it and tell me what happens <img src="smile.gif" border="0">

Hi all!<br />Smooter is RIGHT!<br />EEPROM can be read with modified Ponyprog or with Elnec eeprom programmer. Standard serial (COM) Ponyprog can not read this because COM port can not work at 2,4V logical levels.<br />Modified Ponyprog can read and write at 2.0V and work correctly.<br />Elnec works perfect. For Elnec users: use VCC form pin 8 of EEPROM's socket.<br />Best regards<br />Assen

must the voltage for pony 2,4 volt<br />or for the eeprom

[frigor1]

Where can i find that Elnec and does it works<br />100%.What is a pinout 100% corect.

Does anyone has a solution to read the EEPROM without opening the phone? Don't tell me to buy a JIG box.

VIO why don't u read all posts before yours?????<br />......................

Someone post the I2C modified cable to read the R200's EEPROM with a connector.<br />We already know the pinouts and Vcc. All you have to know to finally read the phone's EEPROM is the right schematics.

Hi Guys ,

i m not having a pony prog , how do i assemble one of these progr.cable to read a samsung r200 & which soft to read it with , where can i download it <br />thanks<br />pete [email protected] <img src="confused.gif" border="0"> <img src="confused.gif" border="0"> <img src="confused.gif" border="0">

Hi to all!<br />Last few days we made some experiments with Samsung R2x0 and I2C cable for it. Here are the results:

PONYPROG RESULTS

With Ponyprog it is very difficult to read eeprom from these phones. In fact, programmer can read and write at very low voltages, but only eeprom, not in phone. When trying to read in phone Err 13 occures, i.e. error initialising device, or device missing.

MODIFIED PONYPROG<br />This is modified ponyprog by us. It uses two MAX232 intarface ICs and 74HC14 logic for bufering eeproms. Sometimes this programmer reads correct, but in most cases same result Err 13.<br />After analysing results and some tests with scope, we find, that it is very important moment of applying VCC to eeprom. This can not be done with Ponyprog and modified Ponyprog

ELNEC and compatible PROGRAMMERS<br />All tests are OK. No problems with reading even some errors found at verify pass. EEPROM is always correct read. There are some problems for writing back, but who cares at this time.

We prepare some pieces of Elnec compatible programmer for selling. For more info soon in advertising forum.

Best regards<br />Assen

Hi.<br />This solution work fine with ponyprog (not modified). Use only SCL SDA GND (ponyprog) and external 3v. conectend directly on Samsung port, and read eeprom with <a href="http://www.ic-prog.com/icprog104A.zip" target="_blank">IC-PROG</a>. PonyProg programm don`t read by this metod.

Thanks ALL for help.

yep Demon_ok it works reading the eeprom<br />I got the codes for net and simlock but phone does not accept it <img src="confused.gif" border="0"> <br />I tried #0111*12345678#<br />and #0149*12345678# (12345678=example)<br />phone diplays "not personalised"<br />can you tell me how to insert these codes and do i do this with or without simcard

Thanks

Hi Tanja1<br />1. Check mail.<br />2. Insert this code without sim card.<br />3. Try read eeprom (from phone) again.

P.S. <br />For me programm work fine. I sucesfully unlocked 3 phones locked on SIM card and Network.

hi demon_ok thanks for quick reply<br />I used this prog already when unlocking by eeprom<br />but now i read eeprom by cable and cannot write file back via cable there for I used prog from pajo and put codes in manualy but phone doesnot accept these codes <img src="confused.gif" border="0">

did you try by cable?

reading is stabile now <img src="biggrin.gif" border="0"> <img src="biggrin.gif" border="0">

now the rest <img src="confused.gif" border="0">
