Here’s how you can download the official Vivo Y19T stock ROM (firmware) flash file on your computer. Once you’ve unzipped the package, you can then flash it using the instructions below.
Installing over-the-air software updates that come directly from the manufacturer or carrier network is what most people do when they want to upgrade the software/firmware to a newer Android release. But there are also times when some users don’t have the chance to flash OTAs or when they do try, the updates won’t work.
Rooted Android users—the guys who open up the device so it can install all applications without limitations—experience this kind of thing all the time. For instance, anyone who has rooted the Android operating system and made changes to the system partition shouldn’t be installing over-the-air updates again because it can cause software-related unexpected behavior. This is said to be because OTA updates never make changes to the system partition. Instead, they are usually just differential updates that patch over files and hardly ever fully replace files.
It’s because of this that the developers who create these tools advise just sticking with custom software if you’ve made system partition changes or had a custom recovery installed. A custom recovery in itself won’t have changed the system partition, but people could also experience unexpected behavior related to the software when going back to the stock recovery because Android might have made changes to it while the custom recovery image was installed. Third-party developers don’t get to see the source code of the stock recovery if changes are made during these times which his what can lead to the problems.
If you do have root access, or you are one of the people who have any number of reasons for wanting to skip OTAs, you can always look into flashing the stock ROM manually by using a flashing tool instead. If you definitely don’t want to stick with custom software or the same software that you’re running already, then you should always flash firmware manually to get back to stock rather than install the OTAs.
But firmware files flashed from flashing tools is also an excellent way for fixing common software problems that people may be facing with their devices. In fact, that’s the main reason people generally look into flashing firmware manually. Once upon a time, users would take their devices to repair centers, and the repair center would flash firmware manually to fix these types of problems. Now you can do it yourself from your own home and save yourself the effort.
All you need is to locate the correct firmware file, know what flashing tool works for your manufacturer (or perhaps system chip), and then the steps to flash the stock ROM.
What Is Android Firmware?
Firmware is the operating system and its applications that control how the smartphone or tablet that runs on Android operates. While you may see the words “software update available” on your device’s display, we call it firmware to highlight its close relationship with the device manufacturers hardware.
If you prefer technical jargon, firmware is the specific programming that gets written to a device’s non-volatile memory. The firmware gets added to the device during the manufacturing process and is the middleman in helping software run on the hardware. Firmware can be written as read-only memory (ROM), erasable programmable read-only memory (EPROM), or flash memory.
The Android operating system is more open than much of its competitors in iOS, Windows 10 Mobile, and Tizen. You always get firmware running on your device out of the box, but if you do not like it, you can swap it over with custom firmware or other firmware versions that were made for your device. This flexibility helps with troubleshooting, or if you know you would prefer a different Android version that was made available.
Why Reinstall Stock Firmware?
Did you think you may need to restore the stock firmware on your device? Here are some of the things that you can achieve with stock firmware files:
- Upgrade or downgrade the version of Android on your device
- Fix common mobile device-related problems, such as unbearable bugs in the software
- Remove custom recovery images such as TWRP
- Unroot the Android operating system, regardless of what method/tool you may have used to get root access
- Unbrick your smartphone or tablet
- Reinstall the operating system
- Fix invalid IMEI problems

Back Up Your Data: You should always back up your data before you begin flashing new firmware files to your smartphone or tablet. All of your pictures, music, videos, documents, etc. should be still on your device after you have updated the firmware, but you may need to restore the contacts and applications from a backup.
Wipe Cache and Factory Reset: Some people claim that taking a factory reset isn’t necessary after updates, but at the very least you should wipe the system cache after installing new firmware. This way you can help eliminate any performance issues and battery draining bugs. Taking a factory reset is the best way of avoiding common problems many users face after applying software updates.
There are some common questions people have before installing firmware files. Here are the ones we are regularly asked:
How to Unroot Vivo Y19T When Installing New Firmware
There can often be a variety of ways to unroot a device that runs Android, and they depend on what method you used to get root access. If you installed SuperSU for root access, then you can open the app and find the option to unroot directly from SuperSU’s settings. On the other hand, if you do not have SuperSU, and you do have an Vivo smartphone or tablet, then you can always unroot by installing the stock firmware. Once you have followed the guide above, your device will automatically be unrooted. You can verify that is the case by installing one of the many applications from Google Play that checks for root access. As long as you are using a reliable app, then typically it will not lie about the root status of your mobile device.
How to Restore Stock Recovery on Vivo Y19T When Installing New Firmware
One of the most common reasons for installing the stock firmware is to remove a custom recovery image and revert to the stock recovery. There is nothing you need to do extra to reinstall the stock recovery on your device; when you install the stock firmware, it will automatically install the stock recovery partition on the device once again.
You can download Android firmware for other Android devices if you have another smartphone or tablet from a different manufacturer.
