In this guide, we are going to discuss tried and tested methods to Fix Recovery Signature Verification on Samsung Devices. If you ever rooted Android phone or tablet, or tried to flash a zip file for some firmware, app, mod, or tweak on Samsung Galaxy phone, then you might have come across two kinds of error that are a common occurrence during such processes: first is the Status 7 Installation Aborted error (see the link), and the other one is Signature Verification Failed problem. In this post, we will be covering the working solutions for Recovery Signature Verification Failed error Samsung Galaxy devices.
What Causes Signature Verification Failed Error ?
As far as the “Status 7” error goes, its happens only on extremely rare occasions. However, this is not the case with “Signature Verification Error”, which is much more common and reasons behind it could be plenty. Generally the signature verification failed error on Samsung devices occurs when you attempt to flash a zip file in recovery mode. The user powers off the phone, presses the usual button combination to reboot the device into the recovery mode, selects the zip file option from the menu, and selects the zip file to install and hits the install button. Once done, the recovery shows that file installation progress message, verifying update package and then if you are really unlucky an errors message in red appears saying “Installation aborted. Signature Verification Failed.”
Although there could be any number of reasons that can cause the error to pop-up during the zip file installation or the rooting process. However, to make it simpler for you guys to understand, we have narrowed down the list to the three main reasons as discussed below along with helpful tips on how to address each cause separately.
Solutions To Fix Signature Verification Failed Issue on Samsung Devices
Let’s discuss the solutions to fix the three main causes of the Signature Verification Failed on Samsung smartphones and tablets.
Re-Download the Zip File
Problem with files in zip format is that they can get easily corrupted. When you try to flash a corrupted zip file, it makes it harder for the recovery to fetch the content of the archive to stop the faulty installation process. Often a slow internet connection and erroneous download process can corrupt files in the zip folder.
Update to the Latest Recovery Version
Most common culprit behind this issue is the older or outdated recovery. Many Android users make this mistake that once they update a custom recovery such as TWRP or CWM on their devices they tend to forget about updating it to the latest version as and when new version is released by the developers. Every new updates, like for any software, comes with important bug fixes and new features. So, if you are still using the same old custom recovery, we highly recommend that you update to the latest version ASAP.
Flash the Zip File Compatible with Your Device
Samsung is famous [sic] for releasing large variety of smartphones and tablets, perhaps more than any other smartphone manufacturer. Let’s take Samsung Galaxy S7 and Galaxy S8 for instance, both lineup of phones have several model numbers and variants with different chips and specs for specific geographic regions and countries. That’s why installation files are released by developers based on the particular device model and specs. And this can confuse users who can download the file incompatible with their device. Always make sure that the file you are downloading is meant for your device model and variant before flashing it.
