FlexiSPY is not responsible in any way for any damages that may incur through following this guide and by reading past this notice you agree to the notice given above:.
Not only that but downgrading may actually cause a performance increase due to the S4, which is getting on in years, not being able to fully run the latest Android OS version as well as something such as the Samsung Galaxy S5. Please note also that in certain geographical regions the S4 may not yet be able to run OS 4. Step 1 — Check the Android OS version is 4. You can see our S4 is running Android version 4.
Basically, without getting too technical we will discuss more about the EFS partition later it is always safe to make sure you backup the phone first before you downgrade. The EFS partition is responsible for allowing the phone to have carrier functionality and make calls such as getting the network identified and IMEI number. You can download EFS Professional from here. You must have rooted the Samsung Galaxy first to install BusyBox and you can head on over to Spy Phone Review here for assistance with that.
You can see that All Partitions is selected but only the four partitions related to EFS are selected to be backed up, then Click Backup to start. Step 3 — Download the Android 4. The next thing that is required is to download the Android 4.
Make sure the details are correct for the S4 you are wanting to downgrade and then click the Download button. Once it has been downloaded extract it to your computer as shown in This Picture. Please note that the ROM files can be several gigabytes in size and downloading them may take some time. Step 4 — Flash the 4. To do this you will need a program called Odin which you can download from here. You need to put the Samsung Galaxy S4 in to download mode which you do so by doing the following:.
Once you launch Odin, if all is successful and the S4 is in download mode, it should say Added! You now click the AP button and browse to the firmware file you downloaded and extracted from the previous step.
The firmware file will be checked and then added to Odin so it looks like the screen below. Due to the filesize of the ROM this can take some time. Step 5 — Resolving any issues — unable to boot up. There have been a number of Android 4. Users of the new handset can download and install the updates officially via Samsung's Kies application or through over-the-air OTA updates.
Many users have reported problems with installing official firmware packages using traditional methods. This generally happens when the device runs on a custom ROM or when the user isn't able to find the update in his or her region, usually because the updates are rolled out region by region, in phases, and the user isn't aware of that. If you are a Samsung Galaxy S4 GT-I user and want to have the latest Jelly Bean update installed on your device but cannot get it the official way, a manual installation procedure is explained below.
Users will need to download the respective firmware package, according to the region they belong to, and then flash it on their handset using a tool called Odin. Android-oriented tutorial website Android Jinn has come up with a list of Android 4. You can click on the link provided with each of the firmware updates to download the appropriate zip file.
A tutorial to install the same follows thereafter. Courtesy: Android Jinn. Users should proceed at their own risk.
