The original N90 upgrade, how about the original N90

After upgrading, the operation is stable, and its original usage is not much different. The interface has become brighter, and when you get used to its practicality, you don't feel fresh. But there are a few things to note:

First,The original 234 version of the five main interfaces appeared together and there is no function,It's to pick up with your fingers,The function of the five interfaces gathered together,It's fun and easy to use,Now it's gone,It's a pity!

Second, a lot of software has not followed up, and the support is not good. For example, QQHD, the latest version can hardly be used, only the version can be used; Feixin, you can't use it, you can only use it;

Third, the software can only be installed in the main memory, not on the SD card, nor on the extended SD card; This is the stupidest bug;

Fourth, the management of the expansion card is not in place, and many things are placed on the extended SD card, which cannot be used;

Fifth, after I used it for a while, it was too slow, so I brushed back to the version, but I couldn't brush it back.

The above is for your reference only.

The difference between Android and Android is really not ordinary, and you will know it when you use it.

The firmware of the original road is generally great, not to mention that the N90 is the flagship of the original road, and it is impossible to be unstable.

However, I don't know what the landlord's technology is, and there will still be risks in upgrading the firmware.

I don't recommend using the system, although it looks good, but N90 many functions are not reflected in it, and I can't even read the USB flash drive.

Mine is this tablet I bought it for almost a month or two The machine is very good There are a lot of software supported Parameters I think you must have seen it The cost performance is very good The quality is also good Although the thing is very good, but the tablet has been upgraded recently Soon There may be a better one to come out But this machine is still worth buying It is recommended to buy If you don't have to worry about it, you can buy it in the store.

Overall, it's nice to be able to buy things without hesitation.

The landlord can consider the U9GT2 of the Kubi Rubik's Cube Better configuration than the original N90 (U9GT2 front 200W directly seconds N90's 30W) The same** Since it was launched in October last year, the sales volume is far ahead of other domestic tablets, and now 8GB is only 999 16GB is only 1199

Very good The screen display is very clear, the Android system is also very stable, and there are now two versions of the 8G version 999 and the 16G version of the 1200

I advise you not to buy it, I am deeply affected by it. On March 3, I bought the original road N90 in the **** Xin Bingmiao store, and it was shipped on March 13, it is said to be a pre-sale test, but in fact, it is not at all, but in order not to occupy the warehouse, they only bought a batch of goods on 7 days, and there was no testing at all.

Today on the 26th, it has only been 13 days since I arrived, and I can't charge it anymore, I hit it with a multimeter, and the charger is normal, indicating that there is a problem with the host. And the customer service in the store is quite poor, and I can't wait for an answer for half an hour, which is simply a non-answer, which makes people speechless. I found out on the Internet that there is an original after-sales service store in Wuhan, and I called ** consultation, and people said:

There is no national warranty at all in the original road, (not bought in a local store will not be repaired at all, you can repair it, two words --- give money).

Online shopping has no right to speak, who do you blame for taking the freight during the warranty period, in order to buy it cheaply and complain here, there are not so many problems with the machines in the physical store.

The Android system consumes power and data.

Press and hold the power button first to see if you can force the boot to enter the system. If you can't enter the system, you can use a card swipe, and the premise of the card swiping is that the ROM that matches the phone model is transferred to the mobile phone SD card.

Card swiping steps: 1, first of all, transfer the ROM that matches your mobile phone model to the mobile phone SD card, and then start to enter the REC flashing machine (the method to enter the REC is to first completely shut down and then press the power button and volume down together to enter, each manufacturer and each mobile phone model is different, so the method of entering REC will be different).

4. Wait for the flashing to be completed, select the first item to restart and the flashing will be completed.

It's impossible not to react, right? Is the driver installed on the computer? If you don't have an drive, you will go to install one.

The first 2% of the electricity can be used for 30 minutes, and then it will fall faster and faster, and you can play games for 7 hours (with the external playback turned off).

Dear Yuandao users, hello!

Please check the Device Manager to see if any new hardware has been found, and if the driver is installed properly. If new hardware is found and the driver is already installed, it is normal. Please try restarting your computer.

Reconnect the tablet. If you still have the same problem, please use the development tools in the link to flash your device. If you still have questions, please call after-sales**.
