ROM downloader

Type the phone you actually have — poco x7 pro, redmi note 13, CPH2451, whatever is written on the box — and this page takes you straight to that brand's own firmware download page. Recovery ROM and Fastboot ROM are both spelled out for each brand, because which one you need depends on whether the phone still boots.

Pick a download

Four routes, depending on what you need on the phone:

Stock ROM download

A stock ROM is the firmware your phone shipped with. You want it back when a custom ROM left something broken, when the phone bootloops, or when you are selling the phone and want it clean. Two file types show up for almost every brand, and picking the wrong one is the usual reason a flash fails:

• Recovery ROM (also called an OTA or full OTA zip). A big .zip you install from the phone's own updater or from recovery. It keeps your data if the version is newer, and it is the safer one.
• Fastboot ROM (also called a factory image). A .tgz or a folder with a flash_all script inside. It writes every partition, so it can rescue a phone that no longer boots — and it wipes your data.

Rule of thumb: phone boots → Recovery ROM. Phone does not boot → Fastboot ROM.

Magisk

Magisk is the root method most people end up on, because it keeps root out of the system partition: you patch the phone's own boot or init_boot image, flash that back, and the system stays untouched. That is what lets banking apps and Play Integrity survive.

• Magisk releases on GitHub — download the .apk from the latest release, not from a mirror.
• Magisk documentation — the install steps, straight from the author.

Grab the boot image for your exact build first (it is inside the factory image or the OTA zip above), patch it in the Magisk app, then flash the patched file with the free Rom Flasher tool over USB-OTG — no PC needed.

KernelSU

KernelSU is the other modern root route, and it works differently: root lives inside the kernel itself, so you flash a patched kernel rather than patching a boot image. On phones with a GKI kernel it is the cleanest option, and some custom kernels ship with it already built in.

• KernelSU releases on GitHub
• KernelSU documentation — which kernels are supported and how to install

Whichever of the two you pick, keep a copy of the stock boot or kernel image you replaced. That copy is what gets you out of a bootloop later.

ROM download

For custom ROMs and the recovery that installs them, the project's own page is always the right source — it is the only one that is current on which device codename a build supports.

• LineageOS downloads — builds per codename, plus the recovery
• TWRP devices — the official recovery list
• Evolution X and crDroid on SourceForge
• NikGApps — Google apps packages that match your Android version

Then follow the written guide for your phone on this site — every step, in the same order as the video.

How to find your exact model

Half of all failed flashes come down to a codename mismatch. Two minutes of checking saves that:

• On the phone: Settings → About phone shows the model name and often the model code. Tap the build number a few times for developer options if you need the exact build.
• In fastboot: the codename is printed on the fastboot screen, and fastboot getvar product returns it.
• In recovery: the filename of the zip you are about to flash should contain that exact codename. If it does not, stop.

Frequently asked questions

Why does this page link out instead of hosting the files?

Firmware belongs to the manufacturer, and this site does not have a licence to redistribute it. Hosting someone else's ROM would also mean serving a file that is out of date within weeks. Sending you to the brand's own download page means you always get the current build, from the source that signs it.

Recovery ROM or Fastboot ROM — which one do I want?

If the phone still boots and you just want the stock firmware back, use the Recovery ROM. If the phone will not boot, or you want to be certain every partition is stock, use the Fastboot ROM — it wipes data but it is the one that rescues a brick.

Can my phone's bootloader stay locked?

For a Recovery ROM from the phone's own updater, yes. For a Fastboot ROM or any custom ROM, no — the bootloader has to be unlocked first, and on most brands that erases the phone.

Do I need a computer?

Not for a Recovery ROM, and not for flashing a patched boot image if you use the free Rom Flasher tool over USB-OTG. A Fastboot ROM is easier on a PC, though, because that is what the bundled scripts are written for.

Is my data safe?

A Recovery ROM of a newer version keeps your data. A Fastboot ROM wipes it. Either way, take a backup first — and note that unlocking a bootloader usually erases the phone on its own.

What if my brand is not listed?

Use the search box and check the closest entry, then go straight to that brand's support site and look for a "software", "downloads" or "firmware" section. Every manufacturer has one; it is just named differently each time.
