Today, we will deal with the Kernel Panic upload mode error that arises when you reboot your Android phone or perform a factory reset. This issue is also common in Samsung devices after a kernel error.
A “Kernel Panic Upload Mode” error on a Samsung phone typically indicates a critical issue at the kernel level of the operating system. Here are some potential reasons for encountering this error:
I encountered this error when I tried hard to reset my Galaxy Note 4 from the recovery menu. First, I wasn’t sure what it meant. It primarily arises when the Firmware is not working correctly. There is some problem with the Firmware, or it has malfunctioned. My phone was rebooting at random intervals after I saw this error. It was troublesome for me. After each reboot, the screen will display this error.
Note: This guide works for every Samsung Galaxy Phone running on an Android operating system.
I tried several things to fix this issue. I will list them all in this post. Maybe they will help you to select the kernel panic upload mode error. Several reasons can be causing this problem. It can either be the Firmware or some app.
- One solution is to uninstall “Advanced Task Manager.” The task manager sometimes malfunctions and starts ending wrong processes, which causes the kernel to crash. Uninstall any task killer or system cleaner app that frees up your phone memory. Instead, use the Android default task manager.
Clear Cache Partition from the Recovery Menu of your Android phone:
If the above solution doesn’t help. Then go to the recovery menu and clear the cache of your phone by following the steps below:
- First of all, turn off your Android phone.
- Once it’s completely turned off, enter into the recovery menu by pressing the Volume Up + Home + Power button simultaneously. Keep holding the buttons until you see the Android figure in the background.
- Now, in the recovery menu. Locate Wipe Cache Partition. Use the volume buttons to navigate to it.
- Now Press the power button to select it.
- After wiping the cache partition.
- Select Reboot system now.
Cache allocated to apps can cause trouble at times. Clearing it enhances your phone’s performance and fixes the unorthodox behaviour of the phone.
Soft reset if your phone is stuck at kernel panic upload mode error:
If your phone is stuck and is unresponsive. The solution to that is a soft reset. The soft reset does not delete any data on your phone. So do not worry.
- In Samsung smartphones, you can soft reset by pressing and holding the Power and Volume Down buttons.
- In the new Galaxy S and Note series models, in order to soft reset your phone. First, connect the phone with a Type C USB cable. Then press and hold the Power and Volume down buttons.
- Now, your phone will restart, and it will start working fine.
If clearing the cache and soft reset didn’t fix the problem, you might have to factory reset your phone. First, follow the steps above to go to the Recovery menu and select Factory Reset/Hard Reset. This will delete all the data on your phone. Make sure you make a backup of your phone using this guide before performing a factory reset.
Flash Stock Firmware on your Samsung Galaxy Phone to fix the Kernel Panic Upload mode error:
Suppose you are getting this error on your Samsung Galaxy phone. Then, use the guide below to install fresh Firmware on your phone if the software is causing the problem. Installing new software/firmware will eliminate kernel panic upload mode errors once and for all.
In this guide, I will demonstrate step by step how you can fix Kernel panic upload mode by flashing stock firmware on your Android phone.
Prerequisites:
- Download
- Download Firmware for your Samsung Galaxy phone from SamMobile. And extract it on your PC.
- Go to the link above
- Enter your phone model.
- Search for the Firmware.
- Select the Firmware that matches your country and brand (e.g., T-Mobile, Verizon, etc.).
- If your phone is unbranded, you can select any unbranded firmware.
- Download Samsung Drivers for Windows. (The link to download the file is under the main heading.) These drivers must be installed on your PC and are essential for your PC to recognize your device.
- You will need a computer for this solution.
Selecting the correct firmware is very important. If your phone is carrier unlocked and has no carrier branding, then you can download the firmware of any country that is not branded. To check the brand, see if the logo of some carrier (like Verizon or T-Mobile) appears when you reboot your phone. If your phone is not branded, you can flash the ROM of any country that is not carrier-specific. Make sure you don’t flash unbranded ROM on a branded phone. However, it is recommended that you find the same firmware as the one that was installed on your phone before it got bricked. Suppose you found exactly the same firmware as the one installed on your phone. Your data won’t be deleted.
Follow the steps to install the Firmware on the Samsung Galaxy Phone:
- First, download ODIN on your PC.
- Next, install Samsung USB drivers for Windows on your PC or laptop.
- Now, turn off your phone.
- Get it into Download mode.
- Press the Volume Down, Power button, and Home Buttons simultaneously. Keep on holding till you see a warning.
- Press the Volume Up button to continue.
- Now open ODIN on your Windows PC.
- Connect your phone to your PC using a USB data cable. ID:COM will turn blue. This indicates that your phone is connected and recognized by your PC. If your phone is not recognized, make sure you have installed proper Samsung drivers on your computer.
- Click on AP or, in some ODIN versions, PDA.
- Select the stock firmware with (.MD5 file extension)that you downloaded from Sammobile.
- Ensure Only Auto Reboot and F. Reset Time are checked in the options, as in the screenshot below.
That’s it. Click on Start and wait for 10 minutes. Now, ODIN will flash Stock firmware on your Galaxy phone. Your phone will reboot on its own after the flashing.
Note: If the firmware you downloaded extracts more than one file, then follow the three additional steps below:
- Put the BL file in the BL tab.
- Next, select the CP tab and select the CP file.
- Finally, select the CSC tab and select the HOME_CSC file.
If the flashing is unsuccessful, try again using some other version of ODIN and ensure you are using your Samsung smartphone’s original data cable.
Reasons for Kernel Panic Error on Samsung Smartphones:
- Android phones can experience glitches or corruption in their operating system. This can happen due to various reasons, such as incomplete updates, incompatible apps, or malware.
- Sometimes, hardware components in an Android can malfunction, leading to kernel panics. This could be due to issues with the CPU, RAM, storage, or other critical components.
- If your Galaxy phone has been rooted or modified (flashed custom ROMs, kernels, etc.), it can sometimes lead to instability in the system, causing kernel panics.
- Certain apps may not be compatible with the phone’s hardware or software version, causing conflicts resulting in kernel panic. Additionally, if an app has bugs or is poorly coded, it could lead to system instability.
