Download

Verify the checksum before flashing. The Updater app on the device finds new builds on its own; this page is for a manual install.

Root

Not included in the ROM zip. If you want root, the recommended kernel is Theettam 2.8, GKI 6.1.176, built for peridot. Flash one flavor in recovery after the ROM. Back up boot and vendor_boot first, and do not flash a boot image by itself.

Start with KernelSU-Next + SUSFS. The DroidSpaces flavors are experimental. Release notes

Build information

Device

Features

• Privacy — PrivacyKit spoofs about 57 framework identifiers per app without root: Android ID, Build.*, IMEI, IMSI, MEID, SIM operator, advertising and Firebase IDs, MediaDRM, MAC addresses, device name, and location and GNSS coherence. Six rule types, 17 device templates, Play Integrity fixes and a TrickyStore implementation inside the framework. Hardware keystore attestation is not defeated.
• Ad and tracker blocking — in the system resolver, enabled by default, no root and no VPN slot.
• Launcher and apps — force-stop from the app long-press menu, a native app freezer, a recorder, and a dialer with unlimited call history and per-call notes.
• BestROM Agent — chat, launcher, phone, files, mini apps.
• Battery and performance — MGLRU, zstd zram, HWUI and dexopt tuning, deep-sleep statistics since boot, and per-app refresh rate.
• Release configuration — ro.debuggable=0, ro.secure=1, no serial console, and restricted networking disabled.

BestROM Agent

Your model. Settings > Custom Tweaks > Advanced > Agent mode.

• Chat — type a task, the phone does it
• Launcher — focus and water on the home line
• Phone — call insights
• Files — clean suggestions
• Mini apps — counter, checklist, daily log, timer

---

Changelog

• Keyboard — LeanType no longer crashes when the suggestion strip is not created yet.
• DNS blocking — the boot seeder now decodes the baked baseline, so the filter actually arms.
• Games — Edge enters Game Mode on its own while a game is in front, and disarms the global input filter until you leave it.
• Theme — one chrome across Settings, Quick Settings and the launcher: 22dp cards, Space Grotesk, Doto on the clock, pill tiles.
• Agent mode menu entry — fixed the Agent mode rows being added to a Custom Tweaks screen that nothing displays, so there was no way into the feature from Settings. They are now on the Advanced tab.
• Agent mode — type a task, the phone does it. You bring the model.
• WebView — replaced the AOSP Chromium prebuilt with Cromite 148.0.7778.168, built from a fork that disables the self-check that crashed host apps. No variations, metrics or component-updater endpoints. It receives no certificate-revocation updates between releases and trails the prebuilt by four Chrome majors.
• Keyboard — replaced the AOSP keyboard with LeanType 4.2.0, defaulting to full height and width, with its own spell checker. Signed with the ROM key, so it updates by OTA only.
• DNS blocking — ad, tracker and malware blocking in the system resolver, enabled by default. No root, no VPN slot. An optional deep mode covers apps that bypass the resolver.
• Edge gestures — edge swipes, key remapping, pie menu, side panels and clipboard history, as a separate app. Inactive until a gesture is assigned.
• Theme — monochrome, true black by default, with dot-matrix type on the lock screen and no window blur. Settings redrawn as individual rows.
• Camera — switched back to MiuiCamera. Fixed captures not appearing in the gallery.
• Files — preloaded MiXplorer as a removable user app.
• Branding — removed the remaining VoltageOS marks from the Updater, status bar and About phone.

Installation

Dirty flashing over an earlier BestROM build is supported. Coming from another ROM, wipe data first.

adb reboot recovery
# Recovery -> Apply update -> Apply from ADB
adb sideload BestROM-3.0-peridot-20260912-0407-OFFICIAL.zip

The zip installs to the inactive slot and activates it. The first boot takes several minutes while apps are compiled.

---

Partition images

Extracted from the release zip and checked against the hashes it carries, so these are the same bytes that build flashes. peridot has a recovery partition on each slot, so recovery.img is a real image rather than part of boot. The system, vendor and product partitions are not here; they come from the zip.

SHA256SUMS.txt · flash with fastboot flash boot boot.img and so on.

A laptop will not finish this. Use ServerHive, then follow the six steps. Python 3.11 or newer is required.

1. 1. Open ServerHiveStart an environment at serverhive.in. Do the rest there.
2. 2. Install uvPaste the first command below. It sets up the tool the connector needs.
3. 3. Download the sourcePaste the next two commands. Wait. This is the long step.
4. 4. Add the connectorOpen that folder in Cursor and click Add connector. Cursor asks before it installs.
5. 5. Ask it to buildSay: build BestROM for peridot. The zip lands in out/target/product/peridot/.
6. 6. FlashSideload the zip from recovery. Do not flash a boot image by itself.

curl -LsSf https://astral.sh/uv/install.sh | sh
