Has anyone managed to test this successfully with 1.55?

Tested and confirmed to work by real professionals.


How to install JLR SDD 155 software?

The main steps:

  1. JLR PanasonicScript-Setup does not need to be installed otherwise.  When the installation is complete, the computer is in reboot.
    2.Install SDD_155.00_FULL.exe
    at the end of the installation of the computer in a reboot.
    3. Install all available software updates in numerical order , for example, “SDD 155.01.exe”.
    4. Copy the patch to the desktop and launch the patch, wait for the window with confirmation of the successful completion of the procedure .
    That’s all. Run the program and begin to use.


Is the SDD crack work with cloned Mongoose cables?

Yep, tested by pros at obdii365.com!

Have tested with:

JLR mangoose sdd/pro (SP205SP205-BSP116), mangoose 3-in-1 cable(SP216-B)

Dealer diagnostic for Land Rover Jaguar Works with VCM Rotunda/VCM2, with both original & clone.

Da-Dongle J2534 VCI (replaced VCM I)
JLR VCI (Jaguar Land Rover approved SAE j2534 Pass-Thru interface)

J2534 EUCLEIA wiScan T6 

I likes that a lot of people used “cracked” SDD with cheap Mongoose cable copies, because first or last some modules and units will be corrupted and JLR dealers can’t do nothing and only try to sell new modules  and no a huge numbers of people in the world who know and have skills how repair it


So can engineering mode be accessed via SDD?

For SDD engineering mode, you’d better use JLR SDD2

Look here: SDD engineer mode setup instruction http://blog.obdii365.com/2016/09/05/set-up-jlr-sdd2-to-engineering-mode/ 

Just says error when i run the file? I have SSD 155 installed ?

Are you running the 32 bit version of windows?  The crack is a bit rudimentary, it doesn’t attempt to locate the correct path for SDD, it assumes its in the default location of c:\Program Files, which isn’t the case on a 64 bit edition of windows.

Fyi, Windows 7 32 bit is the best option, tested!


It says error when i run the file in the 64 bit windows, is there any way to edit it or get a 64 bit one

You might be able to fool the patch by creating a symbolic link. From an administrator’s command prompt try the following:

mklink /D c:\Progra~1\JLR c:\Progra~2\JLR


This will link the location of the software from the 64-bit Windows installation path to the 32-bit Windows installation path.  So that the patch should be able to see the SDD software in what it expects is the correct location.

It may or may not work, as there could be other folders on the filesystem which the patch is looking for.


I just wanted to ask is it possible to use the j2534 cable with land rover diagnostics? I have that cable which I used on my toyota and works fine, I just wanted to know if anyone has tried it with Rover Software or If its possible

I connected VAS5054A according to the J2534 standard and worked with the JLR SDD program. I think that with other devices J2534 there will be no problems.

Patched SDD can’t working with a L405 2016. Also I have create a brick with my D4. I tried update my IPC and got brick. Some guy has helped me. He has activated SDD155 but his SDD has a different interface. I have restored my car with his SDD and with a same my MongoosePro adapter. But I lost some money for restoring. This patch very bad.


How did your friend activate SDD 155?

Just a suggestion, but it may be your interface. Mongoose is no longer supported from version 154 onwards, officially you need the JLR-00001 VCI. Which interface was your friend using?

I’ve not had this patch working correctly in 155, but it seems to work fine in 154 with modern JLRs.


MongoosePro working fine with SDD 155. But I’m using BOSCH VCM2.
I have solution for activation and SDD from 148 to latest 155.03 without patches. Only authentication certificate.
SDD from 151 version has a little different interface. See attached photo.


when you first install SDD and enter the dealer details doesn’t it give a 24 hour grace period before needing to go online to activate? – even without any crack?
If so, would it be feasible to do an install of the latest / a later version, then do the first run and make the mods in the first 24 hours of installing – without the need to butcher the software with some cracks? (But using the engineering code generator if needed)


From the ‘other’ forum:

“SoftwareDownload.htm is in C:\Program Files\JLR\IDS\Runtime\ just double click it enter the last six characters of the VIN and press the tick, you’ll be presented by an engine selection screen before selecting the engine size/type click on the icon that looks like two people and select ‘engineering’ this allows full control over the CCF file and is the equivalent to asking Jaguar for the unlock code from the main SDD session screen. Be careful as this does allow anything to be changed updated, as this is the program that gets called by the the main SDD session when you select recommendations and car configuration update etc.”

I have not yet tried this as none of my JLR vehicles have required it. But having done lots and lots of BMW retrofitting/coding/programming and played with SSD a ton to update countless modules – this feels like an optimum solution for those that require CCF editing abilities and do not otherwise have the ability.

PS: SDD 138 is the version I’m using to run reliably with the available cracks. (The latest is SDD 155 – some pros also confirmed to work) Like the other person said, using knock-off Mongoose cables is asking for trouble. If you are in the EU market get a genuine, it’s cheaper than the average module replacement.


If you are in the US market you can only use Mongoose to update PCM and TCM – you can diagnose all you want. I strongly recommend people buy a clone VCM – its far more stable and useful than any clone Mongoose, plus it works natively with SDD. Mongoose cable, genuine or otherwise require software (usually included with SDD) to function and I have found from years of experience that the more you have running between your vehicle and the diagnostic program, the higher the chances of disaster are.
