well, if i uncheck "continue on errors" the second link gives me an error(not the big core pack, but the first smaller one).
if i check "continue on errors" i update in the order you described and at the end get this:
SQL: SELECT required_9244_02_mangos_spell_chain FROM db_version LIMIT 1
query ERROR: Unknown column 'required_9244_02_mangos_spell_chain' in 'field list'
Table `db_version` have field `required_8993_01_mangos_spell_proc_event` but expected `required_9244_02_mangos_spell_chain`! Not all sql updates applied?
Wouldn't be so frustrating, but the big pack takes about 10 minutes to apply (on my 4th run now)
EDIT: for those having problems with a fresh start and using UDB DB files:
1. UDB 11.6 full
2. 385 corepatch
3. 385 updatepack
4. 386 corepatch
5. 386 updatepack
6. check your db version in mangos.db_version, it will say required_8993_01_mangos_spell_proc_event
7. Go to mangos source folder/sql/updates, find 8993_01_mangos_spell_proc_event.sql
8. Manually install the NEXT sql file with a HIGHER number, in this case 8995_01_mangos_spell_proc_event.sql
9. Keep going installing all sql files with MANGOS in their name until you reach the end of the list
This is time consuming, but will get you up and running
