Students who want to change to a new ROM and use GoogleService need to use this wire flash method to crack the Recovery, and then refresh the ROM or install the GoogleService patch. (Because Lenovo has made a signature in the recovery that comes with the machine, it cannot easily refresh the ROM or install patches through the recovery that comes with the machine)

2.

If only If you want to streamline the system, you can directly root it and then install an R.E. manager to streamline it.

This is a detailed explanation of the above two points. It can also be regarded as a tutorial.

Required items: a data cable, A2207, computer, toothpicks or paper clips (for Reset)

Detailed explanation:

1.

Crack Recovery (referred to as cracked RE), shut down the A2207 (referred to as Xiaoben), open the back cover, and put it aside first.

Extract the three attachments in the download to any folder (I put them in a new folder named 1 under the C drive)

Enter first "MT6575 Flash Driver_Automatic Installation" directory, double-click "InstallDriver.exe" and the system will prompt that the MTK65XX driver has been installed successfully. Click the "OK" button and wait a few seconds, and another USB port will be automatically installed.

driver, click the "OK" button.

Enter the "A2107 Upgrade Tool___20120522 (v3.1216.02)" directory and double-click "Flash_tool.exe"

Click the "Scatter-loading" button and select the "SNARL_IT168_A2207_CrackRecovery" directory "MT6577_Android_scatter_emmc.txt" file, do not check "DA DL With Check Sum"

Click the "Download" button. Be careful to plug the powered-off notebook into the computer at this time. Do not connect the notebook to the computer before that. I struggled with this problem for two days. After connecting to the computer, red, blue, green, and purple colors will appear on the progress bar within a few seconds (I forgot the color order. If the progress bar does not respond, use a toothpick to poke it in the Reset hole on the back cover). The last one is yellow. , a success prompt box will appear after completion.

Close the prompt box, close Flash_tool.exe, and unplug the notebook. At this point cracking RE is completed. You can start the notebook and connect it to the computer.

p.s. It is recommended to use Wandoujia. I have used other software such as Tencent Mobile Genie, but there are cases where root cannot be done.

Next, download two ZIP patches (Root and GMS) according to , and copy the two .zip format files to the root directory on the external card or built-in card through Wandoujia. Shut down. Long press the power button, and after two seconds, press the volume - button at the same time to enter the recovery mode. The volume button is to move up, the - button is to move down, and the power button is to confirm. Select "update

.....from extend sdcard"

(I can’t remember the name, it’s the second option anyway) First select the Root zip file, then select GMS zip file. After success, select the first option to restart the notebook. At this time, the machine has been Rooted and some GoogleServices have been installed.

p.s. a).

If the previous cracking of RE is successful, this step will not go wrong. If there is an error, shut down and reset and then enter Recovery mode to apply these two patches. Try it. If it still doesn't work, repeat the step of cracking RE and crack RE again.

b).

You need to grasp the time to enter recovery. Sometimes the volume button will not be able to enter recovery mode if you press it too late. My experience is that the machine will probably not enter recovery mode after long pressing the power button. It is safer to press the volume-key at the same time at the moment before it vibrates

Last download the streamlined ROM, enter the recovery mode, select the new ROM and perform the flash operation.

2. Root the system according to "" or ""

Both of these are fine, and then install R.E. Manager through Wandoujia to streamline the system by yourself. The system can be streamlined according to "". Note that if you delete Lenovo Desktop here, you will not be able to enter the system desktop after booting.

At this point, some operations of Xiaoben can run perfectly. In addition, after the machine is Rooted, you can repartition the machine according to "". I chose 1.5G. No need to worry about capacity issues caused by installation programs. If an error occurs during repartitioning, shut down and reset, and then perform repartitioning.
