If you have ANY DOUBTS wait for Laser or moderators to help you



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!

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:000000AANow 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)

- Check "Format GDFS" in "Settings" and write it to the damaged phone by selecting it in the MISC-field and pressing "Write GDFS".
If the phone in question is OTP/FLASH CID52, DO NOT CHECK "Format GDFS"

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.
I'll ask the_laser to produce some DB2020 GDFS files in case you don't have a working phone to read from.

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:
;00 MS_GSM900
;01 MS_EGSM900
;02 MS_DCS1800
;03 MS_PCS1900
;04 MS_GSM900_DCS1800
;05 MS_EGSM900_DCS1800
;06 MS_GSM900_PCS1900
;07 MS_EGSM900_PCS1900
;08 MS_DCS1800_PCS1900
;09 MS_GSM900_DCS1800_PCS1900
;0a MS_EGSM900_DCS1800_PCS1900
;0b MS_GSM850
;0c MS_GSM850_PCS1900
;0d MS_EGSM900_GSM850
;0e MS_DCS1800_GSM850
;0f MS_EGSM900_DCS1800_GSM850
;10 MS_EGSM900_GSM850_PCS1900
;11 MS_DCS1800_GSM850_PCS1900
;12 MS_EGSM900_DCS1800_GSM850_PCS1900

or any problam plzz tell i will solve

[Mohsin-*]

or this is 100% solution
First put readsecunits.txt in misc buffer then press write script.

Now you got a file generated that is called YOUR_IMEI.bin
These are the only security units that goes to this phone.
Call this file SECUNITSBACKUP.txt to avoid mistaking.

Now put K790_GDFS.BIN into misc and press "write gdfs"

If your phone is CID49 or CID51 tick FORMAT GDFS WHEN WRITING
If CID52 don't FORMAT GDFS WHEN WRITING

This is to rewrite calibration from another working one.

Once the GDFS is written put Main + Fs + tick COMPLETE PHONE AFTER FLASH
+ Put Your SECUNITSBACKUP.TXT in MISC buffer !

Once phone is finished you are done

[Mohsin-*]

this is gdfs or reasecunit

[hyber_99]

only make the procedure that post @mohsin-* but should be with COM/UFS

that`s the solution to K790 Flashed with a K800 firmware
