Q: i have emptyboard phone. how to convert it to normal ?

A:

warning ! steps are important.

for db2000/db2010:

1. go to empty board tab
2. select needed model, on settings tab: uncheck all settings.
3. select needed cid
- select cid53 for all NEW SECURITY db2012 phones (w200/k320/latest W810/etc)
- select cid49 for all "modern" phones,
- select cid36 for "old" phones (k700,k500,s700,k300),
- select cid29 for ancient z1010
3. press recovery
5. if board is totally empty (new flash chip), select needed gdfs_in_ssw_format
6. select respective EROM (if phone need EROM) from EROMs folder
7. fill IMEI number, check WRITE OTP (it can be done only once, be careful)

 DOUBLE CHECK THAT "OTP CID" (WHICH YOU SELECTED) LOWER OR EQUAL TO EROM CID 

8. press flash

phone now normal retail and can be serviced as any other phone.


for db2020.

1. go to empty tab
2. select any db2020 model, on settings tab: uncheck all settings
3. select cid49 (that is REQUIRED)
4. press recovery
5. if board is totally empty (new flash chip), select needed gdfs_in_ssw_format
6. select respective EROM
7. fill IMEI number, check WRITE OTP (it can be done only once, be careful)

 DOUBLE CHECK THAT "OTP CID" (WHICH YOU SELECTED) LOWER OR EQUAL TO EROM CID 

8. press flash

phone now normal retail and can be serviced as any other phone.


a little example of emptyboard filling for db2020 :

count db2020gdfs_in_ssw_format_CID49_BROWN.ssw.cry as empty "template" of GDFS.
that template should be written on empty flash chip during emptyboard filling process.

then you can write gdfs in .binary format on semc tab, check phone and if all ok - close OTP.

so, lets assume we have 
1. k810 with empty flash chip
2. db2020gdfs_in_ssw_format_CID49_BROWN.ssw.cry
3. k810gdfs.bin

1. go to empty tab
2. select cid49, press recovery
3. add to fw tab DB2020EROM_CNV_RED52_BROWN_CID49_DB2020.ssw (example),
   db2020gdfs_in_ssw_form at_CID49_BROWN.ssw.cry, press flash
4. go to semc tab, flash any situable main firmware
5. on semc tab, write k810gdfs.bin using "write gdfs" and misc. edit.
6. back to empty board
7. select cid49, press recovery
8. add to fw tab DB2020EROM_CNV_RED52_BROWN_CID49_DB2020.ssw ,press flash
9. go to semc tab, flash complete firmware (main+fsimage+custpack) 
OR just flash fsimage,situable to main,written on step4 +custpack
10. now check - phone should be able to turn on normally
11. finally, write IMEI and write OTP, for that 
12. go to empty board,select cid49, press recovery
13. add to fw tab k610_erom_cnv_brown2red.cry,fill IMEI, 
     check "write OTP", press flash.

important!
use only EROMS from setool2 dist\eroms folder - they are resistant for EROM UPGRADE feature (means yours phone will stay not damaged after emma/etc)

Q: after i made csca unlock on k320 phone (or other) i have 5-locks in service menu and phone not accepting any card.
what to do ? i lost x logs !!!

A:
Welcome to SEMC "security addon".
in such case you must

1. select in "misc. edit" file
%setool%\backup\%imei%_%datetime%.fixup (created from version 076)
2. execute "write script".

if you restored .seczone file by accident ( unwise ) - you MUST repeat CSCA unlock (lose another 4 creds) and go to step 1.

important addon

that bug is fixed in R4GC012 firmware series (for k320,w810 phones)
so, if you lost somehow (?) your original .fixup, just flash phone with R4GC012 firmware and redo CSCA unlock.

alternatively, you can just unlock phone using reset procedure.
