Samsung 9300 font door is true or false

Now the i9300 has no problems at all, the 9300 so-called.

The font door only has a very small number of users, and it can be restored, which you can know on the major 9300 forums to see how many 9300 people have happened. In addition, the main reason for those users is that there was a problem of 9300 for a short period of time, which only existed in a small batch of products, and it was a product in the middle and bottom of last year. Now if someone says a font door, it must be a refurbished machine.

And now it's a commercial society, and it's a big deal, and the incident of Apple's fuselage being bent is actually happening to a very small number of users, and the same is true for Samsung, and the things of a very small number of users have been amplified n many times, including ** hype and propaganda from people who don't like Samsung. What can be guaranteed is that now the i9300 no longer has this question.

Questioned. It was a small batch of events from a long time ago, and it happened to a very small number of users in that batch.

My friend's 9300, sleep up and turn bricked. Yesterday, another friend's 9100 was also bricked, water, and it was taken for maintenance and said that it was a font problem, and it was repaired to 600+. I didn't use Samsung, and suddenly it felt like the problem was quite big.

1.Use emmmc software to detect whether your chip has bugs, in fact, the greater use is to look at the writing time of the font to identify whether it is a new machine.

4.It is recommended that you use a dock charger to charge, and if you rush straight, it is best to use the original cable and charging connector. The cut-off voltage of the battery of S3 is, and the cut-off voltage of the general seat charge is, there will be a situation of insufficient charge, in fact, this is better, it can indeed be full, but the price of keeping the battery high energy is to shorten the service life.

There is no such problem after September 12, and you can start with the configuration of the 9305 higher than the 9300.

How to repair a damaged font:

Non-physical damage (there are two ways to repair the font):

The first is JTAG repair, which belongs to the category of software maintenance, which is generally aimed at the situation that the wrong ROM is flashed and the computer does not boot. Specific steps:

a.You need to use the memory card to make a crash repair card, put the repair card into the mobile phone, plug in the coal digging artifact, install the battery and wait to enter the coal digging mode;

c.Fix EFS in flash mode, then repair the signal, and finally modify the serial number in the boot state, so that the repair work is complete.

What should I do with Samsung i9300 burnt font library?

Answer: Generally speaking, there will be no problems according to the official flashing procedure, but just like bank deposits, there are risks. In addition to the software risk, sometimes because of the problem of mobile phone hardware, there is a failure to flash, so the flashing should carefully check the connection of the data cable, in order to avoid the risk caused by sudden power failure, it is best to use a notebook to flash the machine, in addition, be sure to take a look at the online flashing tutorial, and then brush it thoroughly to minimize the risk of flashing.

If it is true that the font is damaged, then it can only be sent to the after-sales department.

If it is sent to after-sales maintenance, then we need to replace the font. The original is about 750, and the replacement is about 700. And after changing the font, there is no guarantee that there will be no more burning.

The landlord's day is mourning, and if you change the font, you will change the motherboard, and you can't afford to hurt it.

The so-called font door refers to the damage of this flash memory.

Because today's mass memory is an eMMC structure, a controller is integrated into the package, which provides a standard interface and manages the flash memory. So whether it's a damaged controller or a damaged flash memory itself, it will cause the phone to fail to boot.

The cause of damage can be hardware, it can be software, the hardware is man-made damage, and at present, it is mainly the defects of the software that cause the damage of a large font.

As far as the current technology is concerned, the problem of font damage caused by software can only minimize the probability, and it is impossible to completely eliminate it, and the key lies in the maintenance after the problem.

If the mobile phone is repaired if it is man-made, it is normal to charge for no warranty. However, the problem of font damage may be caused by natural damage caused by system defects in normal use, and this damage should not be paid by consumers.

If you want to improve in the future, you can use the method of using the computer motherboard, double backup, the computer is also a headache in the early days of the bad BIOS, and later GIGABYTE launched a dual BIOS, prepare a spare one, the broken one will not rot and affect the normal use, and there is time to replace the damaged BIOS.

The mobile phone can also be dual-flashed, one out of the font door, the phone is started from the other, and the data backup is not lost. However, this will increase the cost of silver potatoes by a few hundred yuan to thousands of yuan. Whether consumers are willing to pay for double insurance is a question.
