"Zhuan" [About] explains in detail the problem of cracking mobile phones

\Mobile Phone Cracking
Alias: Mobile XX (major forums have already blocked the word “cracking” and only display “××”)
Refers to using third-party software to “unlock” the permissions of phones with systems like Symbian S60 to gain more usage rights.

Pronunciation
Entry: Mobile Phone Cracking
Pinyin: shǒu jī pò jiě

Explanation:
For example, the Symbian S60v3 system is like a castle with 20 secret rooms (i.e., 20 permissions), each room's door is “locked”!
In the Symbian phone castle, for a program to perform its functions, it usually needs to enter multiple secret rooms to work, which means opening each room's door. But there are guards at each door. You either carry a pass (certificate), or remove the guard (disable), or directly take out the guard (cracking), so no one will block you anymore…

The so-called visa: is issuing a certificate to the program, which is like putting the keys for the doors it needs into a “key ring” for the program. For example, if a software needs to enter 17 secret rooms, it must carry a key ring with 17 keys, meaning it applies for a certificate with 17 permissions. Similarly, software with high permissions needing to enter 19-20 secret rooms, if it has keys for only 17 doors, there will be 2-3 doors it cannot enter, and the corresponding functions cannot be performed. At this point, you need the XX guard!

The so-called ××: is disabling the permission verification, meaning smash all the locks on the doors, open all secret rooms, and keep them always open, so you can freely go in and out!

Reminder: Mobile phone cracking is not protected by law, and cracking some programs is illegal! Be cautious!

Effects of Cracking:
An S60 phone after cracking gains AllFiles capability (see the “20 certificate permission capabilities” in the “Mobile Certificates” entry), allowing free access to any directory to read/write/delete/modify;
Can obtain higher usage permissions (including boot startup);
Can install unsigned software without a certificate and use third-party input methods in more programs;
Can freely install the most classic and luxurious N-Gage games;\You can DIY your own system, such as changing the startup ringtone, changing the startup screen, achieving silent photography, handling system junk, and much more. If you want to learn, you can search for related materials and study on your own……\Risks of cracking\However, many phone enthusiasts still have doubts about cracking their phones. Although there have been no reports of problems occurring after cracking, such risks indeed exist!\After a phone is cracked, although it gains more usage permissions, it loses protection over system files. Legitimate software can freely access them, and likewise, viruses and malicious software can also enter freely!\In fact, safety and danger depend on people; even if the 'doors' are all open, if you do not install problematic software, the 'castle' remains safe; similarly, even if the 'doors' are all closed, if you give the 'keychain' to problematic software, the 'castle' is still in danger.\The journey of cracking\Since Nokia acquired the third edition of S60, many enthusiasts have started their own cracking journeys.\Firstly, the S60 third edition system is a system with great software development potential. Current WinMobile smart systems and S40 non-smart systems are far behind in this regard. The WM system (WinMobile smart system), although inheriting Windows from PC and compressing and expanding upon it, can support numerous EXE format applications. Although it is a trend for future phones, due to market share and commercialization trends, it cannot yet replace S60's position.\However, the development potential of S60 at this time stood out and became a pillar of the market, occupying a significant share among university students and working professionals.\But people were not satisfied with the existing functions of S60. Therefore, Nokia began developing N-Gage games specifically for Nokia phones, SIS format software, and classic SISX software. As for non-Nokia phone users, they could only play most SIS and SISX games through a cumbersome signing process.\Later, with higher demands for phone permissions, smart software developers and enthusiasts came up with various ways to crack phones. Looking back at the development of phone cracking, it has truly 'been through many hardships'!\Stage one: cracking on the computer. At that time, how many enthusiasts even knew the term 'phone cracking'? And who had actually done it?Just looking at the dense tutorials, you may have already hesitated! At this time, cracking phones was the domain of tech enthusiasts! This was the budding stage of phone cracking. Stage Two: Phone-end cracking. Tutorials like 'Pure Phone-end Signature System Cracking Tutorial' began appearing in various forums. Many users gradually learned some knowledge about phone cracking. Gritting their teeth and following the tutorials, installserver and HelloCarbide became well-known. At that time, successfully cracking a phone was absolutely exciting and a matter of pride! This was the development stage of phone cracking. Stage Three: One-click cracking. At this time, the cracking software 'QuickHackKit' became famous for one-click cracking, which could be called a breakthrough! Many 'novice-level' users tried it and suddenly found cracking phones so easy. Phone cracking began to spread widely and was accepted by everyone, marking the start of the 'fast food era' of phone cracking! But, the good times did not last. The Symbian official seemed to have sensed people's enthusiasm for cracking phones and began deliberately preventing it through system upgrades. At this point, many new models and systems could only 'look on helplessly,' and even QuickHackKit was powerless... Could it be that 'phone cracking' really had to end at its peak???!!! Indeed, 'the higher the path, the higher the devil' — everything depends on human effort! With the joint efforts of many cracking experts, HelloOX was created! Once again, it shook the S60 V3 phone world!!! It instantly cracked the FP2 new firmware, 5800, and others, becoming an all-around cracking software for all models and all systems! It can be called a revolutionary product, and from then on, 'phone cracking' continued to develop... Cracking Methods Currently, there are many methods for phone cracking. Generally, software like 'SecMan' is used for permission cracking, or flashing software like Phoenix Flasher is used to flash DIY cracked firmware for flat flashing or upgrade flashing. Below is an introduction to cracking a phone using HelloOX software! (Other methods can refer to forum posts published for cracking related models.) HelloOX 1.03 Introduction: Requirements: Installation using a 17-permission certificate signature. 1. Integrated MAPDrive function, no need to install MAPDrives separately; 2. The virtual drive will automatically unmount without rebooting; 3. On some FP2 devices, ROMPatcher does not work, so FP2 devices no longer force installation or application of patches.4. Because the automatic application of open4all causes N-Gage games to not run, this patch will no longer be applied automatically (manual application is required); 5. For PRE FP1 and FP1 devices, the root certificate is not installed (there is an installserver unsigned patch). If needed, please install it yourself (E:\HelloOX\***rD.sisx); 6. Optional installation of Modo (a file manager with TCB permissions); HelloOX 1.03 cracking method! Step 1: Download and sign-install HelloOX 1.03.Unsigned.sis, and choose the phone storage as the installation location (i.e., C drive)! Then wait for the installation to complete! Step 2: Enter your phone, and you will find an additional program "HelloOX" on your phone. Run it, then the program will start automatically, just wait... Step 3: During this process, a window will pop up asking if you want to install the Modo manager, which is a file manager with TCB permissions developed by leftup. It's very good, but the installation is in English! You may choose not to install it, or find a Chinese version and then install it! Then wait for the program to run automatically until it completes! Step 4: After installation is complete, you will find a new program "ROMPatcher" on your phone. Step 5: Then delete the "HelloOX" program. At this point, the phone is cracked! Main menu explanations: Patch -> Apply: Patch -> Apply, same as the above disabling of permission checking. After applying, non-high-permission file managers can edit system files. But when running NG games, please choose to disable it! Patch -> Add to auto: Patch -> Add to auto-start. This function allows the above-mentioned cracking patches to be applied automatically at startup!
