Lenovo A3000-H firmware/stock rom to unbrick your tablet

Hi,


Found a new firmware and it is for Lenovo A3000-h. The firmware version is 4.2.2 or also known as Jellybean.

I already tested this firmware and it is fully working.




Some pictures below are just an example of my previous post. Replace scatter file with the correct firmware that you downloaded.



You can fix the following issue in your phone:
1. Bootloop
2. Damaged System UI
3. TP Upgrade only
4. Dead phone but it is detected in computer
5. Remove Gmail Account / Password / Pattern Lock (Alternative Way)
6. Privacy Protection Password Lock up


"DOWNLOAD THESE FILES"
Firmware Here -->Lenovo A3000-H Part 1
Firmware Here -->Lenovo A3000-H Part 2
Firmware Here -->Lenovo A3000-H Part 3
Firmware Here -->Lenovo A3000-H Part 4
VCOM Driver -->VCOM Manual
Alternative Driver --> AutoInstaller
SPFlashTool --> LatestVersion 


"Use WinRar or 7zip to extract the firmware"
"Extract the files to your desired folder"
"If you encounter error in flashtool, use different version of it."


"I suggest to use 32bit Windows OS for compatibility of the driver"

"You can also use 64bit version, just disable driver signing or driver signature before installing the driver."



Installing Driver with AutoInstaller

First try the Alternative Driver, which is the AutoInstaller. Just open the install.exe then it will automatically install the driver. To fully check if the driver is correctly installed in your computer. 

Follow these steps:
  1. Turn off your phone (always powered off is a must)
  2. Press and hold volume up or down, or you can simple press the two button.
  3. Insert your USB cable without releasing the VOLUME button(s).
  4. In your computer, it must detect your phone and it will install the MTK Preloader or Mediatek USB VCOM driver.
  5. Repeat 1 to 4 if it does not detect your phone.
  6. If MTK Preloader/Mediatek USB VCOM Driver is installed you are good to go in flashing your phone ^_^

Installing Manually using VCOM Driver



When installing it manually your phone must be turned off, then connect it to your computer/laptop while pressing VOLUME UP or VOLUME DOWN. This will detect and look for the driver.


 1. This is the first time that you will connect your phone and it will search for the correct driver.

2. Check include this location ... ... and click on browse. Look for USB VCOM Driver and Click on 2K_XP_COM folder if you are using Windows XP or Win7 for Windows 7 and then press OK when you are done picking the right folder for the driver.


3. If the driver is successfully installed MediaTek DA USB VCOM will appear in the New Hardware Wizard.

"Your Phone must be turned off when you are ready to connect and flash your phone"


Flashing
1. Launch FlashTool (flash_tool.exe)
2. In Flashtool, Click on Scatter-Loading, and load your scatter file. (see example below)

 3. After you load the file, Include fac.imgUNCHECK PRELOADER and DSP only (Never flash preloader and DSP if available in firmware) If you can't proceed flashing without these two files then proceed at your own risk, press Press Download to Flash your Phone.


4. After you press Download Follow these steps
  • Turn off your phone (always powered off is a must)
  • Press and HOLD volume UP or Down or you can simply press it simultaneously
  • Insert your USB cable without releasing the VOLUME button(s).
  • Keep on repeating until Flashtool detected your phone.
5. If successfully detected just wait until the progress bar reaches 100%. If your phone did not automatically turn on after flashing, remove battery and USB cable. And put back your battery then turn on your device.




"Hard reset your phone after flashing"


Some workarounds:
If you encounter PMT_Changed error here is what you do:
In Latest version of Flashtool

  1. PMT_CHANGED error occur when firmware is not compatible with your phone. Sometimes your phone has a different board version. You should check it too, if your firmware is compatible with your phone. 
  2. Try Firmware upgrade
  3. Try different version of flashtool
  4. Try to set Format All + Download
  5. Or try Manual Format first then Download.


If you encounter Privacy Protection Password:


  1. Open flash_tool.exe
  2. Load the scatter file
  3. Goto Format Tab
  4. Click on Format except bootloader
  5. Press Play/Start Icon
  6. Then remove battery
  7. Insert the battery again
  8. Insert the USB cable (you should hear a beep on your computer, and it should proceed in formatting.)
  9. After done formatting proceed in Flashing.
  10. Goto Download tab (I assume that you loaded the scatter file already)
  11. Uncheck PRELOADER (this is very important)
  12. Press Download
  13. Then remove battery
  14. Insert Battery again
  15. Insert the USB cable (you should hear a beep on your computer, and it should proceed in flashing or downloading the firmware in your phone.)
  16. Power ON the phone after flashing.
  17. Restore your IMEI.

For Invalid IMEI (Does not work in MT6571 SoC):


  1. Root your phone via vRoot/iRoot/Kingoroot or your preferred method in rooting you device. Your phone must be rooted first.
  2. Download MTKDroidsTool version 2.4.8 and version 2.5.3
  3. Enable your USB debugging in Developer Option (you also need this in rooting your phone via PC)
  4. Okay in your PC -- Open MTKDroidstool version 2.4.8 (Mtkdroidstool.exe) first. Make sure that you connected your phone already.
  5. Still in Mtkdroidstool -- Click ROOT
  6. In your phone -- A pop up dialogue will appear, just grant or allow it.
  7. In your PC -- If root shell is granted/allowed, Click in IMEI/NVRAM tab. If it is grayed out this is the time when you open the MTKDroidsTool version 2.5.3.
  8. Enter your original IMEI
  9. Click Replace
  10. Reboot your phone



FOR DAMAGED BASEBAND or UNKNOWN BASEBAND (Your phone must be rooted first)



1. Make sure you have MTKDROIDSTOOL version 2.4.8 or version 2.5.3 (you can search it in google)

2.  In MTKDroidstool (I assume you launch the tool) -- Click in Root. 
3. In your device -- After you press Root, you need to authorize it. A pop up message will appear. Click Allow/Authorize depends on your root application.
4. In MTKDroidsTool -- Click in IMEI/NVRAM, then click in RESTORE.
5. Then look for the folder where you extracted the NVRAM files.
6. Check if the Baseband is fixed. And if the IMEI is fully restored.
7. If Baseband is still Unknown and IMEI is invalid. Then you need to hard reset first your phone.
8. After hard reset your baseband should be fixed already. (base on my experience)
9. If your baseband is fixed sometimes the IMEI is still invalid. So you need to restore the IMEI.
10.  To restore IMEI follow Step 1-4, but you should not restore. You should fill the IMEI then click REPLACE. Then reboot your phone.  VOILA! I hope the phone is fully working :)

I hope this tutorial help you. Please drop a comment if something is not clear to you.

  2. ma'am, sa tingin ko po na boot loop a3000-h ko and itong blog mo solution sa problem ko. May ilang tanong lang po ako kasi first time ko to gagawin and natatakot lang ako na baka ma brick ko phone ko.

    1. sa paginstall ng driver using auto installer, need ba na naka plug in un phone sa pc before installation ng auto installeror need ko lang muna i-install un autoinstller sa pc?

    2. Sabi sa blog mo na kelangan i hard reset un phone "after" flashing. Di ba dapat before flashing un?

    So far un lang and di pa naman ako umaabot sa paggamit ng flash tool. Please po, kailangan ko po ng assistance mo. Thanks in advance and God bless po...

  4. Respected,

    I downloaded all files. But when I tried to open Part 1, 2, 3 files, Winrar reported that it is corrupt (especially system.img file). I also noticed that this file is split across files 1, 2 and 3. How to rejoin all 3 files into one and avoid WinRar error? Thanks.
