What "old boot" means and how we confirm it
The original Thinkdiag comes in two internal versions: old boot and new boot. DiagZone only works on old boot units, and the serial number doesn't tell you which one you have.
So before you pay, we confirm it with you on WhatsApp. If your unit turns out to be new boot, we'll tell you before you pay; in that case the original Thinkdiag T-Code is the option that fits.
What it covers
- 12 V cars, EVs and hybrids.
- Heavy-duty trucks and buses. On 24 V systems the connector needs a 24-to-12 V converter.
- Special service functions. What the app does on each vehicle depends on its make, model and year.
- A 1-year license for US$129 or a 2-year license for US$179.
- The connector is not included: the license is digital and we don't ship anything physical.
A note on the T-Code
An adapter that was already used with DiagZone stops accepting the T-Code for the maker's own app. Decide first which of the two apps you'll use on this device.
Phone or tablet requirements
- Android 7 to 13. On Android 14 or later it only works if the phone or tablet accepts 32-bit apps: if that's your case, message us the model before paying.
- Doesn't work on iPhone, iPad or computers.
- 2 GB of RAM or more.
- Free space: about 16 GB for cars, 8 GB for heavy-duty trucks and 7 GB for EVs.
- Bluetooth and an internet connection.
- A compatible OBD2 connector.
What you get and how long it takes
Once the device is confirmed and the payment clears, we activate in 1 minute to 8 hours. You get your license details by WhatsApp and email, plus a purchase receipt. To complete activation you plug your connector into a vehicle and tell us on WhatsApp.
