How to Fix Start-Up Failed Unbricked Motorola

On this page, I have shared a guide that will show you how to fix Motorola Start Up failed issue and hard bricked problem without using the Lenovo Motorola Smart Assistant Tool. Unlocking Bootloader is a Little bit headache, some brands like Xiaomi, Nokia, and Huawei have made it quite difficult to try the unlocking bootloader, while others such as OnePlus and Google have made it somewhat easy with open hands. As far as Motorola, well it seems to have maintained a balance between custom and stock development and make bootloader unlocking easy.

Although it may not be among the first companies to release kernel source codes, there is still a wealth of mods, tweaks, and rooting guides available for a variety of Android devices from the company. From its popular G series to the Android One devices it maintains, this company is active in the custom development scene. However, it is important to note that these customizations can come with risks. If not done properly or if an incorrect binary file is used, it can lead to issues.

Whether it’s a soft brick, a boot loop, or a hard brick, these are not terms that tech enthusiasts want to hear. However, these situations may arise. When they do, one approach is to try using the OEM’s LMSA Tool. However, it is important to note that this tool may not always be reliable. The Lenovo Motorola Smart Assistant (LMSA) tool may display a “Device not supported” error. It’s always better to be safe than sorry.

While it is understandable for newly released devices not to be supported, it can be frustrating for devices that were released several years ago to still not be supported. When a device becomes bricked and the company’s official Rescue Tool fails to recognize it, it can be quite frustrating. This guide will help you unbrick any Motorola device and fix the “Start-Up Failed” issue without using the Lenovo Motorola Smart Assistant. Keep reading for detailed instructions.

How to Fix Start Up Failed

Follow the Step by Step guide to Fix the start failed issue on any Motorola device without using the moto Assistant tool.

Note: I recommend taking a backup of your personal data, flashing may erase all user data on your phone.

STEP 1: Download Stock Firmware File

First, you have to download the stock firmware for your Motorola device. You can download it from google or from the ever-popular Lolinet Mirror site. they have the largest collection of firmware, Download the correct firmware based on your device’s codename. For example, if you are looking for Motorola One Action, then head over to the Troika folder. So how to find the Motorola device code? Well, you might need to Google it.

STEP 2: Install ADB and Fastboot Tool

Next up, install the Android SDK Platform Tools on your PC. This is the official ADB Drivers provided by Google, so you should use this only (and not any other third-party ADB tools).

STEP 3: Extract Stock Firmware File

You now have to extract the firmware inside the platform tools folder. This is the same folder that you choose while installing the Android SDK Platform Tools. As far as extraction is concerned, you could use the Windows default app, WinRAR, WinZip, or any one of your choice.

Once that is done, head over to this folder’s (platform-tool) address bar, type in CMD, and hit Enter. This will launch the Command Prompt window. keep this window open and go to the next step to unbrick any Motorola device

STEP 4: Connect your Motorola Device to your PC

Next up, connect your device to the PC via a USB cable. If you are able to access your device, then enable USB Debugging from Developer Options. If your device is soft-bricked or in a boot loop, then it might already be stuck in the Fastboot Mode screen. In some instances, your Motorola device might be stuck in the Start-Up Failed error.

If that is the case, then use the hardware key combinations to bring up the Fastboot Mode (in some devices you might then have to press the Power key to confirm it). When your device is connected to the PC via a USB cable and booted to Fastboot, proceed to the final step.

STEP 5: Manually Flash Motorola Stock Firmware via Fastboot Commands

Motorola devices have near about the same partition files, with only a few ups and downs in the system sparsechunk files. With that said, we have listed the fast boot commands for various Motorola devices.

Do keep in mind that I will be updating this list with more Motorola devices. In the meantime, if your device is not on this list, then please refer to the below section to unbrick any Motorola device and fix the Start Up Failed issue without using the Lenovo Motorola Smart Assistant.

Fix Motorola Start Up Failed using Fastboot Commands

So here is how you should carry on with the steps. First off, make sure that the above prerequisites have been taken care of. Just to recap, your device should be connected to a PC via a USB cable and booted to Fastboot Mode. Likewise, you should have extracted the stock firmware inside the platform tools folder. Along the same lines, the CMD window should be opened inside that platform-tools folder itself.

Once all these are taken care of, you just need to match the stock firmware files with the below command and copy-paste each of these commands into the CMD window one by one. For example in some devices, there would be no vendor.img_sparsechunk files, so you may skip the fastboot flash system_b system_b.img_sparsechunk.0/1/2 commands. Likewise, some older Moto devices only have 8-9 system.img_sparsechunk files. So you may leave the fastboot flash system.img_sparsechunk.9/10 commands.
