OK..when I try programming my v5.11 phone with an v4.59 eeprom all the locks are activated.., and unable to open, have i right? anyone who tested write another version?

To KoK..I use a smarcard programmer with an DIL sockel , in witch I can program 16x84 and 24C16, 24C04...for pic http://www.adteknik.se/picture/16.jpg

It's the same chips who is placed in the free-pay-tv-smartcards, and the software i use is http://www.adteknik.se/software/mpgm5.zip and it works fine

has anyone successfuly changed IMEI on a 5110?.., must I be kinda super-duper-hacker to do this kind of thing? =)

Someone know how to use this hex file?
It contains in "eeprom pack.zip" and the name is "5110_511.hex".., there is about 10 different versions in this pack only for the 5110 model
Is about 2KB..., a normal eeprom-hex for the 5110 is about 6BK

Isn't there any program that can calculate a working CRC?
Alex thanx for helping me, can u describe a little more exactly.. from your last entry..?, I didn't understand witch telephone and so.., and what did u mean about good programmer? what difference is it between a good and a bad?

To Bph&co,

Yes you are right about CRC, but mind you
that I was trying to make things very simple.

Anyway, the reason why all locks are closed
because the Checksums or the CRC in the
EEPROM does not match the Checksum and CRC
in the Cobba, MCU, etc. The phone is not
actually locked, but totally disabled and
no unlocker can unlock it. It is useless to
copy other phone's eeprom even with same
version. Changing the imei on the other
EEPROM to match the original EEPROM will
still not solve your problem. The EEPROM
is heavily secured and a single byte that
is not correct will automaticaly disable
the phone, especially if this byte is part
of the IMEI or the lock infos.

You can however remove the locks via EEPROM
modification with correct checksums alone
and not CRC because the lock info is only stored in the EEPROM (I dont know if this is
true for newer versions). But even if your
phone is unlocked, it will still not connect
to any network because of mismatching CRC in
different chips. So it is still useless...

EEPROM rebuilding can be done, however you
still need a TDF-4 Box to flash the phone
again to calcutlate for the right CRCs and
checksums.

Using another phone as a experiment unit will
still not solve your calculation problems
since every phone uses a different "key byte"
to calculte for the proper hex information.
Same software version may mean same algorithm
but still the "key byte" is different so
still useless

Practically, it is very hard to restore IMEI.
When I had this problem, I destroyed the
24C16 by heating the IC. Then I assembled
the 5110 again. Turn it on and saw "Contact
Serivce". While the phone was still on, I
dropped it inside a glass filled with water.
Now phone is totally destroyed! The next
morning I went to nokia service center to
have it fixed ;p They tried to dry the PCB
and realized that EEPROM was burned. They
think that the water caused the EEPROM to
be short circuited and thus burning. Heheheh,
they replaced the PCB and fixed the phone
that I destroyed for me

Do not try to ask the service center to fix
your phone normally. They will know that you
tried to play with the EEPROM and thus they
will not fix it even if you pay them

Best Regards,
Linuz

Hi everybody,
I never tryed to offend anybody, I just
tryed to be useful. If somebody feels bad
about me , I'm sorry.
To X-Shadow - you can get new soldering
iron - maybe Weller, and you'll never over
heat the chips. For me good programmer is
Ice Technology's WinLV 48. It can read every
thing( 29F800 - FlashChip aswell). But is
not cheap. I think if you see the prices for
the software ,that some fellas whant, you
you'll get the feeling that you get your
programmer for free. Just for example -
that guy from NokiaSolutions whant £800 for
IMEI changin' program.
I prefer to see on my bench Logic Analizer from Hewlet Packard then a sh*t program.
Luuk I never told you told to put different
eeprom content. I've told you to try to unlock another phone with the same program
and see which fields are changed after that.
I told you to make a back up of the serial
just in case if this hapend again.
When you know which part of the .hex is
changed you can make some atempts to fix
them. It's better to try with something that
you know then entire 16k file!
Luuk if you think is to difficult just give
it to the Nokia Service.

Thanks

Alex

A friend of mine has just completed the schematics and built a mini-programmer for eeproms, at a total cost of under £5 (5 uk pounds). He has also put the software + diagrams + photos on his site (for free)for promming the eeprom.
http://www.tigger.uk.com

He is a real cool, and very intelligent dude, go see for yourself and build your own prommer (100% working) instead of paying sh*t loads of money to companies.

Good Luck.

If u like his progger, say so.

Thankx

ok.. when i can see network (when my reciever works), but i can't get in to, no access to an operator.., is my IMEI denied?

heh..my cellphone still reboots.., but some of u guys told me to reset it in wintesla..it works.., but next time i reboot the phone it will be the same.., someone have the same problem?

time 4 bed now.. =) seeya

PS. what must i do for gettin access to the other "secret web-boards" ?

And one more question.., has anyone heard of an MOD-CHIP for Playstation 2? what type and so on.. (12C508) ?
