Seems that any version of svctag I tried (1.22, 3.3, 3.4) does NOT work with this model I have replacement board that is blank (tags etc) Thanks sebus
i did it wth asset.com PASS:31/12 (AFAIK this only works i even tried flashing with inbuilt SLIC table) after doing PASS:31/12 i ended up with 2 SLIC table (one, the inbuilt and the other i added using Phonenix mod tool)
that don't surprise me you should have flashed with original dell bios then used asset.com them Pheonixtool.
I was desperately trying to unlock the SLIC, so initially i tried flashing with bios update with SLIC table, but it doesnt showed up in SLIC toolkit. then only I tried asset.com. for asset.com specifically PASS:31/12 only worked, i tried like PASS:1234 etc but none of them worked, only PASS:31/12
