T-Mobile subscribers who own the Samsung galaxy tab 4 8.0 are finding a brand new OTA update arriving in the United States. The baseband version is T337TUVU1BNK4 and we’ve already covered the story here. You can read up on everything inside the update there. There post here is for those wanting to upgrade to the same manually. There are many reasons why people want to upgrade manually. The most popular is skipping the waiting queue. OTA’s roll out in periods to all devices so you may be waiting a long time until it reaches your device. if you are habitually unlucky and far down on the waiting sheet it might be because of your name, purchase date and additional details. Therefore, it’s safe to assume nothing changing for you for future installments.

The secondary reason is many people love customizing their devices with root access, installing custom ROMs and custom firmware. If you are one of those you shouldn’t update Samsung firmware OTA with the system internals unlocked. Sometimes it causes bricking. We think Android 5.0 Lollipop isn’t far away. However, we know custom teams such as CyanogenMod are knuckling down and creating ROMs based on KitKat still. We recently created several guides for the latest M12 custom ROM. You’ll still find plenty of reasons to move away from the default factory restrictions while you wait for Lollipops arrival.

Galaxy Tab 4 8.0

Follow our list of essentials before starting the steps. These are for inexperienced Android users. Advanced Android users may skip ahead if you update regularly and know what you are doing.

  • The following is for the T-Mobile variant of the Tab 4 only. Do not try installing the same file on any other device. It’s dangerous and can soft-brick the tablet. Since you haven’t done anything against T-Mobiles wishes, you may still be able to send it away for repairs. They’ll direct you out of trouble at the very least.
  • If any kind of bricking occurs you are on your own because the steps here do not cover it. Search for relevant Forum threads on the DA Developers website.
  • It is the official software update issued by the tablet carrier network and the manufacturer. That means it doesn’t void any warranties. Additionally, those of you with root access before starting the guide will find your warranty working again after finishing. As soon as you open the internal hardware again with root access it’s void. Furthermore, since you unchained the device, you can’t send it away for repairs. they will not look at the device at this stage.
  • Check the USB Debugging box from the Developer Options menu. You’ll find the Developer Options from the Settings menu. You can’t connect the tablet to the computer and upgrade the OS without checking the box.
  • you’ll need the up to date USB Drivers. If you are connecting the tablet to the computer regularly, you should have these already. However, if you did not connect to the computer it’s time to try to access the pictures from the tablet on the computer. if you are opening the pictures that means the drivers are working. Check for third-party links, links from the official Samsung website or down load and install Samsung Kies if you don’t have the drivers. Kies is a great way to install the drivers, but you must remember to disable Kies before using the Odin tool.
  • We are updating today using Odin. The Samsung team make the Odin app, but the application is only made for Windows users. Those of you with Mac or Linux must find a different way for flashing firmware or find a Windows operating system.
  • It doesn’t have to be a Windows PC. for instance, you can use a notebook, laptop or anything with a working USB slot in the side. We are using the USB slot for connecting the two devices together.
  • You must use a computer, notebook or laptop for using the Odin tool .You cannot flash directly from the tablet.
  • turn off any adware, malware or spyware protection on the Android device. many people install virus protection for when they are downloading applications from the Google Play Store. that’s a great idea, but you should disable them until finishing here. the same goes for your Windows security.
  • The tab comes with USB charging as a default feature. Since we are connecting to the computer for most of the guide, it’ll charge the battery. you must have the computer connected to the wall AC power for this to work. Those without USB charging working ought to reserve roughly 505 batter power. We can’t afford the tablet shutting down before the flashing finishes.
  • You should backup the tablet data if it turns off during the flashing, or if it stalls during the installation. You may need a reset in both cases. factory resets will wipe the data,. You must make copies of everything you don’t want to risk losing such as market apps, pictures, songs, videos, text message and settings.
  • There are several apps available on the market to help you backup the tablet. Some of them are free. You can choose from helium, g Cloud backup, SMS backup+ or sign up to Google Drive for a free limited amount of space. Google Drive is great if you are running out of space on the internal memory and you don’t want to buy the external SD card. You can store data in the cloud with Drive too.
