Well, give 240 points about the baseband issue of the Apple iPhone 4. Please answer carefully.

Dude, to be honest, I can't solve all your problems, I'm not here to mix up, I want to solve them, I'll tell you some of what I know, I hope it helps you.

1.The baseband can be retained, and I have seen a lot of your baseband when I read the post, so it should be no problem to upgrade the baseband. In fact, as long as you don't upgrade to and, it's OK.

2.I don't understand this, but the firmware version upstairs said is too high to be soft decoded, which should be wrong. If the baseband is too low, it seems that it will affect the signal, so the landlord should ask again.

3.Emma, to be honest, the landlord's question is too difficult and overwhelming. The soft solution is not supported, so if you want to upgrade, the landlord still has to use the card.

If you really want to solve the soft solution, please refer to the Weifeng Network Essence Post [Weip Technology Group] There are locked phones, imperfect official unlocks, and SAM virtual sim activation unlocking principles and operations.

It is a base belt of pure bricks, so you must keep the base belt when upgrading. If it's upgraded.,Then the landlord will go to the TB official to solve it.。。。

5.I don't understand this at all.

6.I don't understand ...

The questions are a bit professional, there are really a lot of things I don't understand, and there are a lot of things that are difficult to check.

In addition, I recommend the new heicard of the landlord, which is very practical and consumes very much electricity. The signal is stable.

Tired... I went to rest. Hope it helps.

1> will be kept.

2> firmware version is too high, it seems that it cannot be unlocked.

3> Chaoxue can only untie the baseband (iphone4) at present

4> It is not possible to soft unlock it at this time.

5> The method of brushing the ipad baseband is for iphone3g and iphone3gs, iphone4 can't be brushed, but the current ipad baseband (can be downgraded to the new version of red snow.

6> don't know.

If you have a locking machine, the baseband is, this is the baseband, unlocking is already amazing, it is recommended to keep it.

I just want to say that your question is somewhat professional, top of you. Sit back and wait for the answer from the master.

Your questions are more professional, wait for the experts to tell you the answers. Top you.

Apple iphone 14BasebandThe model number isQualcomm Snapdragonx65。The Snapdragon X65 baseband is the world's first modem family sensitive device to support 10Gbps 5G speeds and the first to comply with the 3GPP Release 16 specification.

Snapdragon x65 performance:

Designed for global 5G deployments, the Snapdragon X65 integrates a 2G-to-5G multi-mode modem and RF system, supports dynamic spectrum sharing, and supports both 5G NSA and SA networking modes, and supports global 5G and 5G multi-SIM cards.

Not only does the Snapdragon X65 bring the industry's broadest feature set to top-of-the-line smartphones, but it also delivers superior 5G performance across a wide range of segments in all major regions, opening up new possibilities for 5G expansion in areas such as mobile broadband, computing, XR, industrial IoT, 5G enterprise private networks, and fixed wireless access.

It is the baseband of iPhone4, which can be unlocked by card, and the latest is ios5, which cannot be unlocked by card for the time being.

It is a 3gs baseband that can be softened.

What is Baseband? What is NOR? What is SecZone? What is NCK?

The baseband is the communication system of the iPhone, which is a program used to control the communication of the mobile phone, control ** communication, wifi wireless communication, and Bluetooth communication. The iPhone has related communication hardware, which needs to be driven by the baseband communication system, and with the normal working baseband, it can make **, send and receive text messages, and use the 3G function. Except, of course, wifi.

The baseband version can be found in the version number used by the modem in Settings - > About This Mac on iPhone. iOS and baseband are relatively independent and work together. After the baseband is upgraded, many soft decodes will fail, and the locked version of the iPhone will not work.

And most seriously, the baseband is almost impossible to degrade. Therefore, for mobile phones with a locked version, the baseband upgrade must be cautious, and it must wait for the crack before upgrading. Of course, the unlocked version should also be cautious about the baseband upgrade.

NOR is a type of flash memory chip. Distinguish it from Flash NandBut it's all memory chips. The iPhone's BaseBand uses this medium to store the baseband.

SecZone is an internal authentication module for Baseband. It belongs to this communication system. This authentication module is so powerful that unless it's a code generated after encryption with Apple's specific private key, everything else will be blocked.

This makes the baseband very difficult to crack. And you can't brute-force it.

NCK is an unlock counter. Inside there is a count value. Reach a certain value.

It will permanently change the iPhone to AT&T or other country contract carriers (Note: This depends on the country you purchased from). With these concepts in mind, we can talk about the perfect jailbreak.

It is recommended to see Encyclopedia.

To put it simply: the baseband is used to manage the iPhone's ** and network access.

iPhone baseband refers to the communication module, which is a program used to control iPhone communication, control ** communication, WiFi wireless communication, and Bluetooth communication. Upgrade the system version, maybe the baseband was upgraded together.

Check out the iPhone baseband version:

Go to your iPhone's Settings > General > About This Mac to check your iPhone's modem firmware (i.e. baseband version).

Baseband, which is the modem firmware. Modulation: Converts various digital baseband signals into digital modulated signals (modulated or frequency band) suitable for channel transmission; Demodulation:

At the receiving end, the received digital band signal is restored to a digital baseband signal. In layman's terms, take playing ** as an example: people are the source of signals, people speak is to send a signal, modulation is to turn the signal of this word into a signal that can be transmitted through the channel, and transmit it to the other party's mobile phone, and the other party's mobile phone receives this signal for demodulation, which is to turn this transmitted signal into the original words we said, so that the other party can hear what I said.

It can be seen that the baseband of the mobile phone is in charge of this part of our communication, and our mobile phone wants to play **, and it must rely on the work of the baseband to receive the signal. I don't know if you understand,

Yes, if it is not necessary, try not to change it, and after changing it, you can't use any lift.
