My BlackBerry 8700 can t connect to the computer

Install a new desktop manager.

Haven't encountered this situation, try it with a different version of desktop manager.

Try a different desktop manager, recommended.

You can contact me directly if you need to.

I check my email every night and get it to you that night.

There are many reasons for this, think about it slowly, first change the desktop manager version, then change the data cable, then change the computer, and then change the phone.

See if you select Large Capacity in the memory settings, and if it's Large Capacity, just turn it off. If that doesn't work, you might as well go to the next desktop management to take a look. I don't know if it's a compatibility issue.

The 8700 is a super good machine, but sometimes there will be SOS for some cards, what should I do??

I bought 8700C for more than half a month.,Basically tossed the bb all over again.,ROM has been brushed to.,The last one is still 114.,Now I basically have a general understanding of Blackberry.,8700 is very real.,But there's a problem that always bothers me.,That's about 8700Sometimes there is a signal that suddenly doesn't.,Show SIM card error,SOS with red signal bar。 After reading a large number of posts, coupled with my own practice, I once again verified that the solution to SOS should at least be alleviated.

1. The signal SOS appears, and the BB returns to normal again, which has little to do with the hardware of the BB itself. I used to sos three or four times a day, but now it's okay to troubleshoot hardware issues.

2. It doesn't matter much if it's a SIM card, it's basically useless to change a SIM card, and it's a waste of money. I haven't had SOS in the last year with my dynamic zone sim v3.,I'm still SOS on 64K BB around the world.。

3、It has nothing to do with ROM.,I've brought it since I bought it)Brush to.,Basically, every ROM is used.,This situation still exists.,In the end, it's still wipe.,Brush into 114 use.。 Of course, there are also individual ones that seem to be . .37 or which ROM signal is not good will appear SOS, change to other versions can be alleviated.

4. According to the forum post, I tried these two points and this method is the most effective now:

a. Change the TLS in the TLS security option to a handheld device.

b. Change the time source in the date and time to off.

5. This is the most feasible way in theory, first of all, before it is changed, BB will often send traffic outward, mini monitor can monitor, the amount of data is not very large, 1 2kb at a time. At this time, BB will switch the signal, because it can be clearly seen that the dynamic zone brand prompt is out, as if it has just been turned on and searched for the Internet. At this point, your BB has completed a network switch.

At this time, if external factors interfere, such as signal strength, placement position, battery level, etc., it may cause BB to fail to switch the signal to 460. At this time, the damn SOS appeared, and the signal could not be found.

6. The two points mentioned in Article 4 are in line with the theoretical explanation, do not let BB automatically switch networks, what kinds of services will cause BB to switch networks, I haven't fully figured it out, but at least one is to want the server to verify the time, and this is not Chinamobile. Changing TLS to handheld devices also prevents BB from automatically seeking services. That's the legendary BB stealing traffic.

In addition, note that select the network in the options, turn on the data service, and then select the network selection mode first, and when you select your signal, you will choose the mobile one with the mobile one, and the one with the Unicom one will select the Unicom one, and then fix the network selection mode on the manual.

The phone is slow to respond.

1. For smart phones, the more they are used, the slower they are, the reason; Install too much software or the software is installed on the disk, (processing method: install the software on the memory card, you can solve the problem if you have installed it, and other smart phones can also try).

Second, there are many junk files in the system, or cookes need to be cleaned up (smartphones can be cleaned up with the security assistant of **, or security guards, and non-smart phones often clean up the cache) to dismantle and infiltrate.

Third, there are too many programs on the mobile phone (Guan Oak Yupei closes unnecessary programs) Fourth, the hardware problem of the mobile phone, (the smart phone has been used for a long time, the machine is aging, and the quality of the copycat machine itself is Liang Wei).
