a question regarding security bypass

[mansi]

hi all....
i am a new user of dream box, today i got my first w850 with damaged gdfs area, after few hours i made the testpoint correctly.
my question is:
after making security bypass can i flash this phone with gdfs at any time?
i mean lets assume that i repaired this phone, and after a while the customer came back to me with same phone [lets say same problem] can i just use security bypass again or should i use testpoint again?
another question, if after testpointing the phone i flashed firmware+fs, does that effect the first step i made?
i mean do i need to use testpoint again after flashing?
in short words what does security bypass do exactly?? how does it handle security area?

TP stage 2 writes a custom EROM with some functions pre-patched/added.
This EROM only can be overwritten if you restore fullflash or make TP Stage 2 again.
If you flash MAIN+RAW_FS+CUSTOM, EROM area will not be touched.
If you write other GDFS, EROM area will not be touched, but, after write a new GDFS, you should to flash main and fs + customize phone again(or infos about CDA, MAIN version, etc will be mismatched from GDFS and phone flash).
Security Bypass recalc security keys, remove unlock area from GDFS, repair IMEI, etc...
