Tri network 3G miracle HTC One cracking test | Ainongji - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

In order to cater to the domestic market, HTC launched the One version for the three major domestic operators at one go, and the three machines are dual card and dual standby. Among them, the mobile version of HTC One has been cracked by various ROM gods, and now can support Unicom 3G and Telecom 3G. We also test to see whether the three network 3G gods really exist.

Of course, the first thing you need is a Mobile HTC One , which could support TD-SCDMA and GSM dual card dual standby ▼

It is clear from the back cover that slot 1 supports TD-SCDMA and slot 2 supports GSM ▼

First of all, let's understand why HTC One may be cracked. Many mainstream mobile phones using Qualcomm SoC now use the fifth generation Gobi 4G LTE wireless baseband. The networks supported by these chips include LTE Rel9, HSPA+Rel 8, 1x/DO, TD-SCDMA and GSM/EDGE, so they can also support 3G of the three major domestic operators. The more common one is MDM9215 baseband chip ▼

Let's take a look at the default situation first. Since it is a mobile version of One, it has to support TD-SCDMA. Through the Speedtest software test, the downlink is 171.5kB/s, while the uplink is only 15.5kB/s（ The test results will be affected by the network and environment. Here are the results of the indoor test for reference only ）▼

When HTC One uses the TD network, the main problem is that it has poor stability, even often stays in the EDGE network, and the system itself cannot be locked in the 3G network.

Through the machine brushing, we tested Unicom 3G again, and the Unicom card was still inserted into the card slot 1 of One, and was brushed in In the future, it is finally possible to lock the 3G network ▼

The following is the test result: 370.7kB/s for downlink and 136.9kB/s ▼ for uplink

The problem with the use of Unicom 3G is still its poor stability. The time for HSPA network to appear is very short, and the network speed is not as fast as other mobile phones using WCDMA. In addition, if you want to use the TD card again after flushing in the ROM that supports WCDMA, you need to manually search the network after each restart, which is very inconvenient.

Finally, we will add the claim After the scan, we can see many CDMA settings. This is the migration of the network part of the telecom version of One ▼

However, after the telecom card is inserted, there is no network. It seems that there is still some problem with this ROM ▼

In addition to the cracking of HTC One, Samsung I9508 has also announced the WCDMA network cracking, and the TD-SCDMA cracking of I9505 has also begun. It can be seen that the mobile phones using Qualcomm baseband are highly plastic in this respect. In the future, we are likely to see the emergence of smuggled mobile phones that support the TD network, which is very attractive to users. At present, the biggest problem is that ROM cracking is not yet mature, and we will continue to pay attention to the progress of these cracking.
