CDMA Workshop is a professional universal service software, developed to work with CDMA 450/800/1900/EVDO(1xEVDO), etc phones, fixed terminals, data cards/modems based on any Qualcomm chipsets. It is the necessary tool for easy and fast programming or re-programming CDMA items to any network, making clone phones, unlocking, reading and changing ESN and MEID, security codes, such as: user lock, SPC, MSL, FSC, OTKSL, Minlock, etc, authentication security codes, such as: A-key, Ssd_a, Ssd_b, and many other things. CDMA Workshop combines all major functions and operations which are necessary for full-functional work with CDMA phones and it is a «must have» software for every serious technician, cellular/repair shops and dealers.

"Nam Programming" tab  -  screen shot

In order to program phones to a necessary network you must write network settings such as Mcc, Mnc, Sid-Nid pairs, Primary/Secondary channels, etc. You can write these parameters here, as well as read existing network settings from any phone and create your own collection of network settings for each network you necessary.

Note that some networks with enabled roaming function are required to be programmed with valid IMSI also. Otherwise, incoming calls will fail. You can write valid "True IMSI" to phone in this tab also.

"Evdo" tab  -  screen shot

There you can read and write PPP / EVDO settings and authentication parametres (user names, passwords).

"Terminal" tab  -  screen shot

This is a low-level terminal for advanced users, which allow you to send internal commands and receive answer from a handset in Hex or Ascii format. It useful in different investigation and custom situations, for example it allow you to repair damaged SPC (0x00, 0x00... 0x00 for example) when a handset does not accept any SPC.

It has a counter of total amount of bytes in commands, automatic CRC calculation and commands history, in order to facilitate usage.

"Memory / Eeprom" tab  -  screen shot

  • Read/Write/Scan - it is the Peek/Poke based functions. At first, you can scan memory by using the "Scan Memory" function, in order to get a memory map and find readable addresses. After that, you can use these found readable addresses in Read/Write functions and in "Universal RAM" methods ("ESN", "SPC", "Cave" sections, see below).

Note that some models may restart when you try to get access to unreadable areas.

  • "NV Items" section  -  You can backup / restore any amount of NV items here. Doing so you can backup / restore all phone settings: user settings, network settings, security settings, RF calibrations, etc. CDMA Workshop has ability to make FULL backup of NV items for models (many modern and old models) which restart at trying of access to some NV items.

  • "Flash" section  -  These functions use bootloaders for different MSM chipsets in order to Read/Write flash-memory directly. By using these functions you can create your own collection of full-flashes and use them to upgrade firmware, as well as to repair phones with "software" problems (corrupted EFS, etc).

Supported chipsets: MSM 3000-5500, 5100, 6000, 6025/6050, 5105/5500/6000 (ZTE / Axesstel)

"Security" tab  -  screen shot

  • "ESN" section  -  You can change ESN (Electronic Serial Number) here. This function is useful for repair damaged ESN or write new one in order to make clone phones. Note that some brands and models will allow you to write new ESN by using "default" method after entering internal security password (16 digits, see below) only (ex. Samsung, Audiovox, Hyundai, Sky, Pantech models, etc).

  - "Universal RAM" method will search all ESN addresses in RAM memory and save them to a file, after that it will use these addresses to write new ESN directly. This method is very useful to use for brands and models for which ESN cannot be changed by the other methods, for example: some Epsilon, Compal, Aiko, ZTE, Axesstel, Novatel data cards, PPC6800/Mogul, PPC6900/Vogue/Touch and many other brands and models.

  - "Universal EFS" method will work on the majority modern models based on non-locked EFS2 (Embedded File System), such as: latest Samsung Sprint/Verizon models,  Treo 700, 755, etc, Audiovox/UtStarcom models (6600, 6700, 120sp, 7025sp, etc), Kyocera new models, new LG models, Samsung SCH-V, S-series, Motorola MS-series (MS400, MS500, etc), ZTE phones/data cards and many other brands and models.

  - "Kyocera method" - This method is developed to work with Kyocera models based on MSM chipsets up to MSM5100 (ex. 2035, 2135, 3035, 3245, 5135, 7135, s14, 1135/1155, 2235/2255, 2325/2345, SE44/SE47, Blade/Phantom, etc). For newer Kyocera models you can use "Universal EFS" method.

  - "LG method" - You can write new ESN on most LG models by using this method.

  - "Sanyo method" - You can write new ESN on Sanyo models up to Sanyo 8300 by using this method.

  - "ZTE / Axesstel method" - You can write new ESN on models based on MSM5105, 5500, 6000 chipset (ex. C100, 150, 160, 170, 180, 190, 200, 201, 202, 204, 220, 230, 231, 401, 631, 632, 705, etc, etc. Nokia 1255). You can use this method to write new ESN on many Axesstel models also (ex. P800, L800, L1900, etc).

  - "VK Mobile" - You can write new ESN on most VK_Mobile models by using this method (ex. VK-100c, 200c, 220c, 300c, 600c, 650c, x100, 700c, etc).

  - "Samsung EsnDev" - This method is used for Samsung models for Korean, Asia and Oceania, Israeli, etc markets, such as: SCH-X, E-series, some V-series and some A-series (ex. a562).

Some brands and models use encrypted ESN inside and/or hide real ESN and do not allow to read real ESN by standard methods (ex. all Samsung SCH-V, S, B-series). You can use "Real ESN" option to read real ESN for such models. This method is Universal and can be used on any CDMA models.

You can see ESN prefix (ESN owner or phone manufacturer) in pop-up hint by moving mouse cursor to the ESN field here also. This feature is very useful to see - is the current ESN original or it already has once been changed.

P.S. The other available methods of changing ESN, please check in Demo version.

  • "MEID" section  -  You can enable/disable and change MEID (Mobile Equipment IDentifier) here. Newer models may use MEID as a additional authentication parameter (with ESN). When MEID is enabled and used in phone, then ESN is called pESN (pseudo ESN) in this case and pESN must be matching current MEID.

CDMA Workshop will check pESN and MEID matching at first reading of phone and show a notification message automatically if pESN and MEID is not matching each other.

CDMA Workshop will automatically re-calculate and write valid pESN at changing MEID with using available methods.

Some brands and models use encrypted MEID inside and/or hide real MEID and do not allow to read real MEID by standard methods. You can use "Real MEID" option to read real MEID for such models. This method is Universal and can be used on any CDMA models (MEID based).

  - "Universal EFS" method will work on the majority modern models based on non-locked EFS2, such as: Samsung, Kyocera models, etc.

  - "LG method" - You can write new MEID/pESN on all LG models (MEID based) by using this method.

  • "SPC" section  -  You can read/write and send SPC (Service Provider Code) unlock code to a phone here. Note that some brands and models will allow you to read current SPC by using "default" method after entering internal security password (16 digits, see below) only (ex. Samsung, Audiovox, Hyundai, Sky, Pantech models, etc).

All CDMA phones are locked by using of SPC. You must unlock phone by using "SPC - Send" button, before writing: network settings (NAM), PRL, NV Items, etc. CDMA Workshop will show a notification message automatically, if phone require SPC to be entered before such operations. When phone is unlocked you can change SPC to any value.

  - "Universal RAM" method can search and extract all 6-digit security codes (SPC, MSL, FSC, Minlock, etc) directly from RAM memory. Security codes always located somewhere in RAM memory. This method is very powerful and used for models for which security codes cannot be read by the other methods: models which have no any EFS support, old models or models which use locked EFS. (ex. all new Sanyo models, Treo Centro, BlackBerry models, Sierra AirCards, etc)

  - "Universal EFS" method will work on the majority modern and old models based on any versions of EFS and read all 6-digit and 4-digit (user lock) security codes.

  - "Direct Eeprom" - This method is quite similar "Universal RAM" method, but designed to work with eeprom. Sometimes security codes are located in eeprom (ex. old models, old Samsung models, all LG models, etc).

  - "LG method" - You can read SPC on most LG models by using this method.

  - "SonyEricsson" - You can read SPC on all SonyEricsson models by using this method.

  - "Motorola method" - You can use this method to read SPC, MSL and user lock for many Motorola models with "syn_feature" file in EFS (ex. C290, V710, E815, V3C and many other models).

  - "Kyocera Minlock (SPC3)" - This is a universal automatic method, used to read Minlock unlock code (also known as SPC3 and Master code) on Kyocera models based on EFS1 (kx1, kx4x4 / ke4x4, se44, se47, etc). For newer Kyocera models you can use "Universal RAM" and "Universal EFS" methods to read SPC3.

P.S. The other available methods of reading SPC, please check in Demo version.

  • "Password (16 digits)" section  -  Some brands and models are protected by internal security password (16 digits). You must send a valid password by using "Send" button for such models, in order to unlock writing ESN and reading SPC by using "Default" methods, as well as reading/writing memory.

For example Kyocera, Sanyo, LG, etc do not use this kind of protection in their models. Samsung Sprint models use the same password for all models, it called "Samsung - (default)" in the list of passwords, same password is used in most other Samsung models from other countries and regions (Latin America, Asia and Oceania, etc). You can add very easily your own passwords to the general list of passwords also.

But even if you dont know password or it does not present in the list, you can read SPC, Cave settings (A-key, etc) and change ESN by using "Universal EFS" methods.

  • "User Lock" section  -  You can read/write 4-digit user lock here, as well as enable and disable it.

"Cave" tab  -  screen shot

  • "Cave" section  -  The A-key is used in many CDMA networks in authentication process (besides a basic authentication parameters - ESN (MEID) and phone number) in order to avoid cloning. Security of the A-key is critical in such CDMA systems. To make clone phones A-key, Ssd_a (Ssd_b) must be also programmed in such networks. You can read original Cave (Cellular Authentication and Voice Encryption) settings and write new ones in this tab.

  - "Universal EFS" method will read Cave settings on the majority modern and old models based on any versions of EFS.

  - "Universal RAM" method can search and extract Cave settings directly from RAM memory. Cave settings always located somewhere in RAM memory. This method is used for models for which Cave settings cannot be read by the other methods: models which have no any EFS support, old models or models which use locked EFS.

  - "LG method" - You can read Cave settings on most LG models by using this method.

  - "SonyEricsson" - You can read Cave settings on all SonyEricsson models by using this method.

  • "A-Key Calculator" section  -  You can generate a valid A-Key with 6-digit checksum here. This is sometimes required for testing the phone's A-Key entry function as well as for the phone's activation. It used to be possible to obtain a valid A-Key with cheksum only from the cellular operator itself, now everyone can easily generate the secret checksum value, enter those numbers into the phone just using the phone's keypad. When you want to program the new A-Key into the phone over the keypad you must enter 26 digits (20 digits A-Key in DEC + 6-digit checksum).

"Other" tab  -  screen shot

• "PRL" section - You can read and write PRL files (Preferred Roaming List) here.

  - "Read" - You can read PRL by using "Read" button from any existing phone and create your own collection of PRL files for each network you necessary.

  - "Write" - Use available methods to write PRL: Universal method for most CDMA phones, LG and Sanyo methods (non-standard) specially for LG and Sanyo models.

You can clear available timers, change R-Uim settings and make rebuild Eeprom/EFS on this tab also. Rebuild Eeprom is designed for Samsung models only, but this method is works for many other brands also, such as Withus, Epsilon, Compal, etc. Sanyo method will Reset/Rebuild EFS for new models started from Sanyo 8300, it will also open locked EFS and reset all security codes to default values. Rebuild EFS is necessary in order to change ESN on new Sanyo models also.

"Monitor" tab  -  screen shot

The "real-time network monitor" function is allow you to observe online/offline phone activity and status. This function is very useful to finding and solving problems with non-correct phone programming when phone cannot make calls or cannot find network.
