HOW TO WORK WITH A1-BASED PHONES



basics:

- in signed mode firmware with specific CID can only be applied to phone with same CID
- in unsigned mode or in signed mode with enabled alternative security bypass you can ignore firmware CID.
- patch unlock is temporary, after reflash phone will be locked again
- full unlock is permanent

FLASHING OF DB2000,DB2010 PHONES

common for all CID:
1. go to semc tab, select proper model
2. add to firmware area correct MAIN, FS IMAGE parts of firmware. order not important.
3. select in misc. field needed CUSTPACK (.zip archive with customization files)
4. if you do not have CUSTPACK, you MUST check on settings "customize phone after flash"
5. please read notes below
6. set other settings according your needs.
7. back to semc tab, press flash.

CID 17,24,41,42,54

unsigned mode
3. skip
4. skip
5. on settings, uncheck signed mode, alternative security bypass, preloader security bypass,customize phone after flash.

for BROWN CID 41,42,73 you must disassemble phone and do testpoint operation.
testpoint is simple GND wire attached to specific points on phone board.
(upload testpoint pictures)
in that case, step 5 will be:

5. on settings, check only "use tespoint (gnd method)"

you can use special 'dual" usb+serial cable in order to significantly increase flashing speed for such phones.
you can not use script for such phones.

CID 16,29,36,37,49
signed mode
5. check signed mode

unsigned mode
5. on settings, uncheck "signed mode", "alternative security bypass"

you can only use USB as interface for phones with CID 49, some CID 36 phones can be upgraded to CID 49 via writing of corresponding EROM.
restoration files required for phones with CID 49

CID 50,51,52,53

signed mode
5. check signed mode

standalone altbypass mode
5. check "signed mode", "use alternative security bypass"

restoration files required
bypass package required
please read FAQ post about alternative security bypass

that is preferred mode if you want to do some additional operations during flashing process.

please note, that if you put in misc. edit any file, which is NOT custpack archive, it will be treated as script command file.

UNLOCKING OF DB2000,DB2010 PHONES

CID 17

1. select com/ufs as interface
2. go to lg tab
3. select correct model
4. on settings tab, uncheck all settings.
5. back on lg tab
6. press unlock button

please note, than recent firmwares can't be unlocked with such method,use cid 41,42 path or downgrade firmware.

CID 24

1. select com/ufs as interface
2. go to sharp tab
3. select correct model
4. on settings tab, uncheck all settings.
5. back on sharp tab
6. press unlock button

in some cases you must flash special patched firmware from support area before unlock.

CID 41,42

1. select com/ufs as interface
2. go to lg tab
3. select correct model
4. on settings tab, uncheck all settings.
5. back on lg tab
6. press unlock button

if phone BROWN CID 41,42 then you must disassemble phone and do very easy testpoint.
testpoint is simple GND wire , attached to needed point on phone board.

step 4 should be like that:

4. on settings tab, check "use testpoint (gnd method):

(upload testpoint pictures)


CID 16,29,36,37

1. select com/ufs as interface
2. go to semc tab
3. select correct model
4. on settings tab, uncheck all settings.
5. back on semc tab
6. press unlock button

that CID is obsolete and upgrade to CID 49 via writing corresponing EROM recommended.
you can not use USB as interface for such phones with CID.

recovery operation supported for such phones, damaged EROM can be restored without problems.
no any special files required for such phones.


CID 49

standalone method

1. select com/ufs/usb as interface
2. go to semc tab
3. select correct model
4. on settings tab, uncheck all settings.
5. back on semc tab
6. press unlock button

you can not use USB as interface, if SCRC damaged ( IMEI mismatch in IDENTIFY output )
restoration files required for that method.
that files could be downloaded from support area or created automatically :
place main part of unsupported firmware in firmware area,press identify and attach phone with unsupported firmware.

CSCA method

1. select com/ufs/usb as interface
2. go to semc tab
3. select correct model
4. on settings tab, check "signed mode"
5. back on semc tab
6. press unlock button

that is not recommended method for unlocking such phones, slow and useless.
you can not repair damaged SCRC via that method.


recovery operation not supported for such phones, reset operation should be used in order to repair damaged EROM.
you can repair damaged GDFS, damaged SCRC standalone for such phones.


CID 50,51,52,53

standalone patch unlock method via alternative security bypass

1. select com/ufs/usb as interface
2. go to semc tab
3. select correct model
4. on settings tab, check "signed mode","alternative security bypass"
5. back on semc tab
6. press unlock button

you can not use that method , if SCRC damaged ( IMEI mismatch in IDENTIFY output )
restoration files required for that method.
bypass packages required for that method.
please read FAQ post about alternative security bypass.

standalone RESET-based method

1. select com/ufs/usb as interface
2. go to emptyboard tab
3. select correct model
4. on settings tab, check "signed mode"
5. back on emptyboard tab
6. press RECOVERY button
7. on settings tab, UNcheck "signed mode"
8. add to firmware area corresponding EROM from EROMS\ folder, EROM CID should be >= OTP CID
9. press flash

that is recommended method to use with that phones
you can fix SCRC using that method

CSCA method

1. select com/ufs/usb as interface
2. go to semc tab
3. select correct model
4. on settings tab, check "signed mode"
5. back on semc tab
6. press unlock button

please note,that phones with cid51,52,53 require credits and internet access in order to unlock using CSCA method.
that is obsolete method, should not be used,because it long and credit-consuming

recovery operation not supported for such phones,
reset operation should be used in order to repair damaged EROM,damaged GDFS, damaged SCRC.

CID 54

1. select com/ufs as interface
2. go to lg tab
3. select correct model
4. on settings tab, uncheck all settings.
5. back on lg tab.
6. add to firmware area special patched firmware from support area.
7. press flash

if any trouble happens, you must reflash phone with original not patched firmware.

disassemble phone.

1. select com/ufs as interface
2. go to sharp tab
3. select correct model
