Factory Reset for Huawei S7 Tablet

If you are like me, living in South Africa and you do appreciate a good tablet when you can have one you would have bought the latest Huawei S7 tablet now selling fast in South Africa. MTN has one for R99 (top up or regular) with a free 75Mb data for 6months. CellC has one also with data for 24months. The Vodacom option is even more expensive. But All I care about is the tablet. So I went for the MTN one. The problem is Huawei S7 does not support 3rd party launchers. I have always liked using Android mate, because it doubles as a folder explorer, installer and application manager. So if you are really like me and made the mistake of installing a thirdparty launcher and later you shutdown your tablet and went to sleep; you will be surprised when you wake up to find that your brand new tablet is no longer responding to any kind of touchscreen input when you power up and wants to work. You cannot even shutdown the tablet except you take out the battery. If USB debugging is not enabled before you got here you will find that it is much more difficult to fix your tablet.

But do not disappear there is a solution. And I will take you through it here. (disclaimer: beware this is a factory reset. All data on you tablet will be erased. You can use my included file for the resetting if your tablet is compatible to MTN huawei S7 firmware. For Other firmware please try androidtablets forums for any help. No guarantees are given here express or implied. This worked for me so the probability it will work for you is 1 in as many as there are android huawei tablets in the world). Just try it.

Step 1: Download MTN South Africa Huawei slim 7 tablet firmware here.

Step 2: Create a folder named dload unzip the download from step 1 and copy these two files unlmt.cfg and UPDATA.APP into the folder dload. Copy dload and contents to your Micro SD card. If you have a Micro SD card with an adapter that will do the job. With the adapter the SD card will fit into your laptop or computer card reader. Make sure the sd card is empty and formatted. Drop the dload folder into it. Make sure inside the folder is only two files and not another folder.

Step 3: Remove the battery from your tablet insert the SD card into the tablet at the SD Card slot. Replace the battery.

Step 4: Start the tablet by pushing the power button. And relax and watch. A progress bar should appear and soon begins to fill up. When it is competed an OK will appear under it.

Step 5: Remove the SD card and push the power button again to restart the tablet. (You may now plug the tablet to a power source to start it charging. The next process is intensive and your battery might go flat. As a precaution use the power charger not the usb charger for now)

IDEOS logo appears and blinks about three times. Service provider logo appears and stays for a bit longer. Then the Huawei home launcher home screen appears. At this stage do not touch the tablet yet as more updates of the firmware will be taking place including update of the touchscreen and coulometer firmware. After that your tablet is back and as good as new.

Warning: Do not reinstall a third party launcher yet. Watch this space. I will post a workable solution soon that will allow you to install third party launchers without breaking your warranty. If you have a hitch give me a post. If it works for you recommend it to others by sharing this post on Facebook, twitter or whatever you use or let me know by posting a comment. Goodluck. Taskjo.

  1. thanks for the info. does this firmware also support for vodacom slim s7?

  2. John568, this firmware is for MTN south africa. Of course it will work in other slim 7 whether CellC or Vodacom. But this firmware is customized for MTN and will probably invalidate your warranty if installed on a device supplied by vodacom or CellC.
    \There is a firmware for CellC and Vodacom, if you want it, give me a shout.

  33. Hi, I have an S7 Slim and would like to remove an old e-mail account. It seems as though I would have to resore factory settings in order to accomplish this.
    Is is then necessary to reload firmware after a restoring factory settings?

    ReplyDelete
    Replies
    1. resetting returns your s7 to what is on it at factory level. it will still work very well just the way it was when you bought it first time but you need to re install all your apps and data. so back up first. remove the email you want to from the back so you don't restore it after re set. but factory reset is not the last option for dealing with an email removal just be sure what you want.

  34. OMG THANK YOU SO MUCH JOHANN!!!!! It works in Canada now!!

  35. To get screen working, tablet must be rooted with USB debugging enabled.

    Use included pc software (or similar) to access filesystem of tablet and locate the file /system/etc/bluetooth_power.sh (note the /system dir needs to be remounted read-write)

    Add the following two lines to the end of the file:

    echo 1 > /sys/cap_touchscreen/boot_complete
    echo 1 > /sys/cap_touchscreen/state

    Save, reboot, enjoy :)

  52. Hi Johann, your link to the firmware is not valid anymore (not working)
    I have downloaded the official firmware from the Huawei Website for the Ideos S7 slim. And followed your instructions to install it, but I just get a white bar and all 3 lights (home, menu and back) are flashing fast. Left it now for more that 30 minutes, but it is still the same ??? What is the problem? Model S7-201u (Firmware: HUAWEI_S7-105_FIRMWARE_android2.1_C60B013_General_Channel_05010MCC)
    Please help
    Thanks Cassie - cassie8@gmail.com

    ReplyDelete
  53. Have now installed S7-201u firmware. But after restart getting: Sorry! Activity Home (in process android.processs.acore) is not responding

    Is this Website still active ????

    ReplyDelete
  54. Anyone having the flashing of the LED problem. Chances are you downloaded the incorrect firmware version.

    The bars in the progress bar should be red. The LEDs do flash every 2 seconds.
    Please use this link --> http://consumer.huawei.com/en/support/products/index.htm?pname=S7-201u&pcode=S7-201u.
