: what is procedure for unlock db2012/db2020 by flash patch ? what problems i can meet and how to resolve them ?

a:

terms:

- you can only unlock by flash patch db2012 (k320,w200,etc) and db2020 phones with FLASH CID 49,50,51
- flash CID can be discovered with IDENTIFY button
- you CAN NOT repair phones with damaged/foreign GDFS (red blink when startup)
- you CAN NOT use altbypass on PNX5230 phones (z310 at present) and NEW SECURITY PDA phones (maybe i will do it, maybe will not)
- you will need ONE CREDIT per ONE PHONE.

howto:

1. open setool2, select correct model.
2. go to settings tab.
3. enter your server, user, password
4. mark "use server for csca flash/unlock", "enable alternative security bypass", "unlock after flash"
5. go back to semc tab. PRESS SAVE.
6. i recommend to use dcu60 cable with any db2020 model - it is FAST and STABLE.
7. now, did you download new rest files ? no? then do it.
8. press identify, look for current firmware version and try to find it in new rest files.
9. found ? nice. press unlock now - you will see smth like

if you get

Code:

bypassing DB2020 security...
smth wrong with GDFS format,error is:30
prepare failedthat means you HAVE NOT SELECTED BOTH "USE SERVER" and "USE ALT BYPASS".
re-check settings, not forget to save profile after you selected settings.

if you get

Code:
Firmware lock check determined.
llbug: can't get all data, got:0 expected:1926
processing error when readingwhile using com/ufs cable that mean problem with your cable/drivers.
install latest drivers, play with latency.
but better use dcu60 cable with any db2020 phone.

once again IF YOU GET

Code:
FOUND: R1ED001_CXC1250556_VODAFONE_MW
Restore from:R1ED001_CXC1250556_VODAFONE_MW
can't open file "C:\setool\rest\R1ED001_CXC1250556_VODAFONE_MW "

very rare, with some bad cables (thats happens only with some improperly made ufs/com cables),
phone fails to detect interface and you will get following:

Elapsed:8 secs.solution:

first, get normal 4in1/ufs cable (with both ports soldered and good pinout)

next,
select interface com/ufs
semc tab, select proper model.
settings, check ONLY "use server",
add to flash files ONLY main firmware image, situable for selected model
press flash
check if phone turning on. it should.

redo unlock procedure, read topic for start first.
(remember - dcu60 is fastest and safest way to work with db2020 ph
