me or lasyk take no responsibility for any thing u try to do from this link TAKE A GDFS BACK UP FROM UR PHONE !!!!!!!THIS IS NOT FOR A NEWBE CHANGE UR GDFS WILL KILL UR PHONE IF U DONT KNOW WHAT U ARE DOING
Case:
Let's say you have a DB2020 phone with some GDFS issue, say you wrote K800 firmware to a K790 and now you have "no network".
Solution:You'll have to rewrite the original GDFS. Sadly, most users never back it up before proceeding with whatever operation they intended to do in the first place. This is done through the "Read GDFS" button in SETool, btw . it will produce a .bin-file named with the phones IMEI and can be found in your SETool basedir. Take good care of it.
Now, lets say you didn't back up the phones GDFS and did something to screw it up. Then you have a problem, because rewriting it with another phones GDFS will screw the security units and the phone will be bricked. Generally a bad thing, right ?.
Luckily, there is a way to solve this and the procedure is as follows:
Use only COM/UFS interfaces (but i used it with out my setool3 box just used se tool lite just make sure u dont turn ur phone on at all till it is finished )
1 (Optional): Back up the corrupt GDFS (yes, even though it's corrupted, so you have a full backup just in case). Again: "Read GDFS". Move it to a safe place on your HD, this is to avoid accidentally deleting it and for avoiding confusion with all the other txt-files that will appear later on.
2: Create a scriptfile (a normal txt-file will do) with the following contents:
Code:
---------------------------------------------------------------------------------------
gdfsread:00020e5a
gdfsread:00020e48
gdfsread:00010851
gdfsread:00000006
gdfsread:0000000E
gdfsread:00000013
gdfsread:0000001C
gdfsread:00000018
gdfsread:000000AA
---------------------------------------------------------------------------------------
Now save it. Name it "readsecunits.txt" or whatever. Select the file in SETool's MISC-field and press "Write SCRIPT".
All the read units will be stored in a single file named by the phone's IMEI.
rename it as "secunitsbackup.txt" to avoid confusion
3: Apply the GDFS from a working DB2020 phone.
- Read it out from the source phone (it will be stored in the SETool basedir named by the source phone's IMEI)
Do NOT turn the phone on afterwards.
4: Now, you'll have to write back the original units. Apply the "secunitsbackup.txt" you created by selecting it in the MISC-field and pressing "Write SCRIPT".
Voila, it should have done the trick.
u may have to hold the 2 and 5 button to get setool lite to recognise ur phone not the c button
Another method (Without the need for GDFS backup/etc...)
Create and execute the following script:
gdfswrite:000000ACXX
Set XX to whatever corresponds to your phones bandlock:
Code:
---------------------------------------------------------------------------------------
