Cydia is a world-famous alternative app store for iDevices that distributes third-party apps to iOS devices. Many iDevice users know about Cydia and Jailbreak, but some don’t know of them. Therefore, we came here with few frequently asked questions with answers about Cydia Jailbreak.

1. What is Cydia?

Cydia is an alternative app store that allows you to install third-party apps and tweaks on iPhones, iPads, and iPod touches. If you are an iDevice user for a considerable time, you may have already noticed that the Apple app store doesn’t offer you third-party apps to install on your device. Therefore, you have to use an alternative app store on your device to get third-party apps and tweaks on the device. And that alternative app store is indeed the Cydia app store because it provides the best-featured third-party apps, extensions, tweaks, add-ons, games, and themes for iDevices.

2. What is Jailbreak?

Jailbreak is the process of accessing iOS system files beyond the manufacturer restrictions. A jailbroken device allows its user to do whatever he/ she wants to modify the device. That is something you don’t get by default to your device. In fact, the jailbreak is the process of installing Cydia on iDevices. When you run a jailbreak tool on an iPhone, iPad or iPod touch, you get the Cydia installer with it by default.

3. Can I install Cydia without Jailbreaking?

No, you can’t install Cydia on iPhones, iPads, and iPod touches without jailbreaking the device. Jailbreak is the way of installing Cydia so that it is essential to jailbreak an iDevice to install the Cydia app. If you don’t have a publicly released jailbreak application, at least you must use a semi-jailbreak tool on the device to install Cydia.

4. Is it safe to use Cydia on iDevices?

You need to jailbreak your device to install Cydia, which means you need root access to your iOS device. And that means you have to break into the security measures that Apple has imposed. It may leave holes to enter points for malware or viruses, but there are only a few that have been recorded all these years. However, many iUsers choose to jailbreak and install Cydia anyway, considering the beneficial outcomes they get. In fact, we can’t tell you whether to download Cydia or not to. Because it is up to you to decide whether you are going to download Cydia or not. If you focus on the positive side of Cydia, which is about the beneficial facts you get by jailbreaking and installing Cydia, install Cydia on your device. If you focus on the negative side of Cydia by thinking of its risks, threats, and disadvantages, don’t install Cydia on your device.

5. What are the benefits I get from Jailbreaking?

When you jailbreak your iDevice, you get access to the Cydia third-party app store. And it contains amazingly featured tweaks and modifications that can enhance the performance of iDevices. These apps and tweaks are not authorized by Apple Inc. because the jailbreak breaks through the security to install Cydia. However, you can use these amazingly featured tweaks, themes, apps, modifications, ringtones, etc. and add new features to your device. Adding these third-party apps and tweaks on iDevices leads the path to add extra functionality to your device. And eventually, you will get a well-customized device with feature-rich apps and tweaks. Furthermore, jailbroken devices can remove unwanted stock apps from the devices once and for all. This is something special that you don’t get to your iDevices by default.

6. Is Cydia Free?

Cydia is a complete freeware application that doesn’t require any payment to install it on iDevices. In addition, most of the apps tweaks in the Cydia app store are free, but some of them require a small payment to be installed and used on iDevices.

7. Is Jailbreaking illegal?

No, the jailbreak is not illegal. The Library of Congress ruled it as a legal exemption to the DMCA, or Digital Millennium Copyright Act in 2012. And that makes it legal to jailbreak iDevices.

8. Is Cydia Safe to Use in 2025?

Yes — Cydia is 100% safe, especially when downloaded through trusted sources like www.cydiafree.com. Our platform offers a clean, jailbreak-free installation method that ensures your device stays secure while unlocking powerful customization options. You can safely explore iOS 26-compatible tweaks, themes, IPA sideloads, and exclusive tools — all without voiding your warranty. Join millions who trust CydiaFree to enhance their iPhone experience with confidence and freedom.

Ivoclar Programat P90 is a classic, robust dental furnace first introduced in 1987 . Known as the first Programat to feature a membrane-sealed keypad

, it remains a staple in many labs for its reliability and simple 7-segment display interface. Key Technical Specifications : 90 programmable slots for various firing cycles. Dimensions : 415 x 433 x 295 mm. : approximately 16.5 kg. : 220 V (50/60 Hz). : Includes a vacuum pump and compressing function. Common Error Codes & Troubleshooting

If your P90 is showing an error, it often relates to temperature deviations:

: The T-value (high temperature) is lower than the actual temperature currently in the firing chamber. The Ivoclar Programat P90 , originally released in

: The vacuum switch-off value exceeds the pre-set high temperature (T).

: The B-value (stand-by temperature) entered is invalid (outside the 100°C–700°C range).

: Temperature is too high (exceeds T-value by more than 12°C).

: Indicates a "control unit malfunction," which may require resetting the furnace or replacing the internal battery. Quick Programming Guide To set a program on the membrane keypad: Select Program and enter the desired program number. Set Temperature to enter the high temperature. Adjust Times for holding time (default is 1 minute) and for closing time (default is 30 seconds). Vacuum Settings

to toggle and set vacuum switch-on/off points. Ensure the red light indicator appears as expected for confirmation.

: Once the buzzer sounds, place your ceramic on the mount and press to begin the cycle. For official maintenance, Ivoclar recommends regular Silver Test

It seems you are looking for a specific service or repair part for the Ivoclar Programat P90 furnace, likely a "fixed" component (e.g., a fixed heating element, fixed thermocouple, fixed firing tray, or a fixed software part). The phrase “manual fixed piece” is ambiguous, so here are the most likely interpretations and where to find help:

Part 4: Common "Fixed" Repairs for the P90

Searching "ivoclar programat p90 manual fixed" often leads to hardware fixes, not just software. Here are the top DIY fixes that lab managers perform manually:

Safety & preparation

• Wear PPE: eye protection, heat-resistant gloves as needed.
• Ventilation: ensure adequate room ventilation.
• Inspect furnace: clean firing chamber and ensure thermocouples and tray are intact.
• Tray/loading: place restorations centered on firing tray; avoid contact between pieces. Use recommended firing supports (sagger or firing pins) per material.

Cons

• Limited Automation: The manual and fixed program nature might limit flexibility for some users who require more programmable options.
• Space Requirements: While compact, it still requires dedicated space in a laboratory setting.

Step 3: Executing a "Fixed Manual" Firing Cycle

Once in standard (non-service) mode, here is how to bypass corrupted auto-programs entirely:

1. Press the 'P' button repeatedly until you see "User" or "Manual" (depending on firmware version).
2. Press Arrow Up to select.
3. Input your parameters manually:
   • Start Temp: 20°C
   • Heating Rate: 55°C/min (standard for e.max)
   • Final Temp: 840°C (for crystallization) or 1530°C (for zirconia)
   • Hold Time: 7 to 10 minutes
   • Vacuum: On (or Off for glaze/baking)
4. Press Start.

Note: If the vacuum fails in manual mode, the furnace continues heating—unlike auto mode which aborts. This is dangerous for dental ceramics. Use this only if you have manually fixed the vacuum pump relay.

Part 6: When "Manual Fixed" Fails (Contact Ivoclar)

If you have performed the Service Mode reset, cleaned the vacuum valve, and reinstalled the firmware but the furnace still refuses to run a full sinter cycle, you likely have a hardware failure of the main control board (PCB).

Part numbers to search for:

• Main PCB for Programat P90 (2005-2012): 615288
• Main PCB for Programat P90 (2013+): 649577
• Heating element 230V: 553125
