I have this line in assembly: 0000000000019cdc         tbnz       w20, objc_ivar_offset__TtC7ChatGPT8AppState_$defaultActor, loc_19d94

Its value is 04 05 00 37. But in my hex edit software it displays 83.
I want to modify it to achieve this:
You're correct that the `tbnz` instruction at `0x19cdc` currently controls the branching behavior to the error message at `loc_19d94`. By default, it's conditional, checking a specific bit in the `w20` register to determine whether to jump or continue.

If you want to bypass the error message and force successful access, you can modify the instruction to always branch to a successful path. Here's a step-by-step approach to achieve this:

### Solution Outline
- **Objective**: Modify the conditional branch to always skip the error message.

### Step-by-Step Solution

#### 1. Find the `tbnz` Instruction
1. **Open Hopper**
   - Open your binary in Hopper.

2. **Locate the Function `sub_19c28`**
   - Find the function `sub_19c28` in Hopper.
   - Look for the `tbnz` instruction at address `0x19cdc`.

   ```assembly
   0000000000019cdc         tbnz       w20, objc_ivar_offset__TtC7ChatGPT8AppState_$defaultActor, loc_19d94
   ```

3. **Identify the Hexadecimal Representation**
   - Find the hexadecimal representation of the `tbnz` instruction.
   - In ARM64, `tbnz` instructions typically start with `37` or `36`.

   Example:
   ```assembly
   0000000000019cdc: 37 60 00 14  ; tbnz w20, objc_ivar_offset__TtC7ChatGPT8AppState_$defaultActor, loc_19d94
   ```

#### 2. Replace `tbnz` with `b` Instruction
1. **Open the Binary in a Hex Editor**
   - Use a hex editor like `Hex Fiend` or `HxD` to open the binary.

2. **Locate the Offset**
   - Find the offset of the `tbnz` instruction in the binary using the address from Hopper (e.g., `0x19cdc`).

3. **Replace `tbnz` with `b`**
   - Replace the `tbnz` instruction with an unconditional branch (`b`) to skip the error message.
   - In ARM64, the unconditional branch (`b`) uses the opcode `14`.

   Example Replacement:
   ```assembly
   Before:
   0000000000019cdc: 37 60 00 14  ; tbnz w20, objc_ivar_offset__TtC7ChatGPT8AppState_$defaultActor, loc_19d94

   After:
   0000000000019cdc: 14 00 00 14  ; b loc_19db4
   ```

4. **Save the Modified Binary**
   - Save the modified binary with the changes.

#### 3. Test the Modified Binary
1. **Run the Application**
   - Run the modified binary to verify that the access check is bypassed.
   - Ensure that the application functions correctly.

### Summary
- Replace `tbnz` with an unconditional branch (`b`) to always skip the error message.

### Important Notes
1. **Backup the Original Binary**: Always keep a backup of the original binary.
2. **Legal and Ethical Considerations**: Make sure to comply with the app's terms of service and licensing agreements.

### Further Explanation

#### ARM64 Instruction Format
- **`tbnz`** (test bit and branch if not zero) examines a specific bit in a register and branches if that bit is not zero.
- **`b`** (branch) is an unconditional branch that always jumps to the specified address.

#### Example Disassembly

```assembly
0000000000019cdc         tbnz       w20, objc_ivar_offset__TtC7ChatGPT8AppState_$defaultActor, loc_19d94
```

After replacement:

```assembly
0000000000019cdc         b          loc_19db4
```

### How to Calculate the Branch Offset
- The branch instruction (`b`) takes a 26-bit signed immediate value to specify the target address.
- The immediate value represents the offset from the address of the branch instruction.

#### Example Calculation
- **Address of `tbnz`**: `0x19cdc`
- **Target Address (`loc_19db4`)**: `0x19db4`
- **Offset Calculation**: `(0x19db4 - 0x19cdc - 4) / 4 = -10`

Thus, the instruction `b loc_19db4` will be encoded as `14 00 00 14`.

What should I put into the filed now?
