5110 v5.29 "contact service" fixed with repaier by Guar

[mobilemonster]

I tested this sw on 5110 5.29, and it is really 100% working on this version.
99% of problems can be fixed by recalculate checksum. 1% is destroy of system area, and can't be fixed i think :-(
Such problem can appear in following cases :
1.Short circuit of some pins in eeprom, while unlocking. But not pin6-7.
2.Using ground without any resistors and without your own body.
3.I think, static electric from your body, so toutch ground first when unlocking 5.36(3210) or 5.29 (5110).
4....(send if you know some else)

whats the name of the software & where could we get it???

Hello Guys,

I have very funny experience with 6138 v5.01.
I know this is a very old phone, but I hope
this will be a useful information to you all.

EEPROM was damaged 100% To fix it, I did
these steps:

1. Erased whole EEPROM of phone (But I cannot
erase the lower portion which has sort of
pattern if you look at it).

2. Now phone says contact service. I used
old Ola-sp (for old 5110) by Zulea to unlock
it. This is the only program that can trick
a Blank EEPROM! Nokia Tool can do nothing.

3. Phone says contat service still, but
WINLOCK read phone as open but with funny
MSIN fields. So I used Nokia Tool and Winlock
to restore the MSIN to 00101, 00, 00, 0000001
(I dont know if this is called MSIN, but you
guys know what I am talking about right?)

4. Now I have phone unlocked but still
contact service because no IMEI and Security
Bytes. I load IMEI using Wintesla and
Password Calculator.

5. Now phone says insert Sim Card, but all
locks now are locked again!!! it is locked
to FFFFFF, BB etc...

Reason: Security Bytes are not valid unless
I will flash the phone I noticed that
the Security Bytes HEX are just similar to
IMEI bytes and not unique like what you see
on a working EEPROM.

6. I can unlock phone by this method: Short
pin 5 and 6 and press 'SW reset'. Phone
powers up and says 'Contact Service'. Now
I used Nokia Tool to unlock. Even if I just
unlocked Lock 1, all locks were immediately
disabled! Phone is now TEMPORARILY open, but
not working Or, another method is to
change the security bytes into FFFFFFFFFFF...
You will get contact service, but if you read
with WinLock all locks are open.

If I restart the phone, phone locks itself
again!

Does any body know what the Security Bytes is
based on??? Security Bytes is the first 11 or
12 (not sure) bytes in the EEPROM and after
little part after IMEI.

Here is Map of EEPROM (please correct errors)

X = FF (1 byte)

security bytes imei
X X X X X X X X - X X X X X X X X
security bytes???
X X X X X X X X - X X X X X X X X
7sp lock info security code Checksum
X X X X X X X X - X X X X X X X X


I think if some of you guys can find a way
to rebuild Security Bytes, then Manual
EEPROM rebuilding would be possible (I am
not sure about this, maybe there are other
security bytes in the lower part of EEPROM
like the parts that I cannot erase earlier)

Upto now, my 6138 is still dead for over 1
year! I can only use it with an Original
Motorola Test SIM!

I am not sure about other phone types and
versions, so if your phone is not really
damaged, do not try my procedure above.

For shorting pin 5 and 6, I used a prod with
10K connected to GND of cable and my finger
touching the metallic part.

Good luck !!!
