How to Format a Single Partition of Huawei CUN U29:
1. The steps below explain how to format a single partition of a Huawei CUN U29 using SP flash tool.

3. Select the scatter file for your device by clicking choose besides the scatter-loading file’s dropdown bar.
4. In the windows that appear next, navigate to and select the Huawei CUN U29 scatter file.
5. You should now be taken back to the SP flash tool window, Click on the Format tab.
6. Tick the checkbox beside “Manual format flash”
7. Open windows explorer and navigate to the location of the scatter file you selected earlier on then open it using Notepad++
8. Scroll down the contents of the scatter file till you get to the partition you wish to format [in my case, I’m trying to format FRP partition]
9. Input the values of Linear_start addr and partition_size into SP flash tool then Click on Start
Linear_start addr = Begin Address
partition_size = Format Length10. Power off the phone (with the battery in) then connect to the PC via a USB cord. Once successful, you should get a green tick.

- Once SP flash tool has detected your device, avoid disconnecting till the task is complete as this might cause the Huawei CUN U29 to go dead.
- If you accidentally selected “Autoformat – Format all”, your device will go dead and you’ll need to flash full Huawei CUN U29 stock ROM to revive the phone.
- Avoid using a random Huawei CUN U29 scatter file (even though its for your chipset) in Sp flash tool. Just because a scatter file is for your chipset doesn’t mean it contains the same partition info. Formatting with a wrong scatter file could result in more problems than you initially intended to fix.
- SP flash tool was created by MediaTek Inc. so credits to them for the tool.
