    K790 isn't compatibile with K800's firmware, cuz he doesn't have a videocall camera, so there is another structure inside the phone, like mohdumer said, only thing that you can do is to customize...

    WARNING: Do Not Use Any Other GDFS For Your Phone Since GDFS Is Unique To Your IMEI. Just Reflash Your Phone, Customize It And THEN Rewrite Your Origanal Backed Up GDFS.

    first write back your oringal gdfs back-up from your phone, then get some k790firmware or k818i firmware and re-flash the phone,
    the k790 uses different bands to the k800i thats why you can't get a signal, there is no point flashing a k790 to a k800i, or k800i to k790,

    You Find A Lot That A K790 Can Be Converted To K818 But Please DONT TRY Cause It Will Damage Your GDFS And Again You Wont Get Signals. The Most You Can Do Is Customize Your K790.

    Copy pasted from SETool forum...

    Just follow this procedure carefully...
    -----------------------------------
    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: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)

    - Check "Format GDFS" in "Settings" and write it to the damaged phone by selecting it in the MISC-field and pressing "Write GDFS".
    if you have CID52 phone, 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 of quick recovery (without all mess with gdfs backup/write/etc)

    create and execute following script
    gdfswrite:000000ACXX

    set XX to valid for your phone:

    ;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

    You Sure Flash correct customize pack because network problem relate to customize pack.
    2)if gdfs is damage use setool2(box) and write new gdfs phone(because your phone is cid49)

    ok so if i flash my phone with valid firmware (ie same model) is there any way somthing like this problem could happen to me? or is this only posible with incorrect model of firmware

    oh ya, aswell if it were to happen, could u re-flash your phone with the sony ericson flash tool, that gives you back branded firmware, and have it work?
