What is the XperiFirm Tool?

Well, several brands are selling smartphones across the globe. All have their own set of features and are always in a race to leave behind the other brand. One of the most important after-sales services that Android OEMs can provide to their users is the regular and timely rollout of the updates. We always come across news of a smartphone getting a new update. These updates are pretty essential to keep the devices up and running with the latest trends and safety measures to keep the data of the users safe and also provide them with the latest Android experience. However, there are certain times when the update is rolled out for a region, it reaches a certain set of people, but the other set of people are devoid of it. It is a fact that OEMs roll out official updates in a staggered manner meaning that not all the devices will get the updates at the same time.

But, there are numerous tools available for each OEM that help you to pick up the update package file for manual degradation which means that you do not have to wait for the official OTA to arrive. Such a tool for Sony Xperia smartphones is the XperiFirm tool. You can make use of the XperiFirm Tool to download the latest stock firmware for any Sony Xperia phone and upgrade your device right away even if the OTA is not yet available for your region. There are two panels in the layout of this tool, one that depicts the smartphone names and the other that depicts the updates. You can check if a new update is available for your region and then click on it to download the latest firmware for your Xperia phone pretty easily and safely.

XperiFirm v5.8.1 – Latest

Changelog:

v5.8.1 [November 4, 2025]:
- NEW: Added build for Windows ARM64.
- TWEAK: Some improvements on the server-side database format for future extensibility.
- FIX: Visual glitches fixed via custom components and some mouse events corrected.
- MINOR: The format of Downloads.xml has been further optimized.
* Due to this change, XperiFirm 5.8.0 can no longer read the database and is not supported.

v5.8.0 [November 3, 2025]:
- FIX: Sony's customization search API is dead. We're back to manual lists. Will scan myself and use the help of the community. Big thanks to the few who helped fill in the missing CDAs and SPCs.
- FIX: Major code refactor and some UI changes.
- MINOR: The format of the Downloads.xml has been redesigned for ease of use. However, if you break its format, XperiFirm will remove and recreate it.
- MINOR: Since Flashtool seems to be abandoned for many years already, the "fwinfo.xml" file will no longer be created in the unpacked firmware's folder.
* Due to this API change on Sony's side, XperiFirm 5.7.1 is no longer able to fetch customizations from Sony and is not supported.

v5.7.1 [June 9, 2025]:
- FIX: Sony's host name for firmware updates has been changed.
* Due to this host name change, XperiFirm 5.7.0 may no longer be able to connect to Sony's API.

v5.7.0 [January 25, 2024]:
- FIX: Replaced old ZipArchive library to fix unpacking firmware over 4 GiB in size.

v5.6.5 [December 21, 2021]:
- FIX: Fixed connection error when trying to request a customizations list from Sony's server due to API change.
- MINOR: Model tags (like "dual" and "Wi-Fi") will no longer be included in the full device name, as it's no longer used in official device naming.
- MINOR: The "Wi-Fi" tag is now colored dark-red ("dual" tag is still colored blue). Implementation has been added for additional tags that may appear in the future, with different colors, without having to update the application.
NOTES:
* Due to this API change on Sony's side, XperiFirm 5.6.2 is no longer able to fetch firmware from Sony and is not supported.

v5.6.2 [September 29, 2021]:
- FIX: Fixed inability to download new firmware (i.e. 61.0.A.14.3 for Xperia 1 III) due to missing MD5 checksum information for the firmware files.
NOTES:
* Since the MD5 checksum is missing for these new firmware, integrity verification for them is impossible. However, if any of the files happens to be corrupted, unpacking will most likely fail. This should not be a problem if you're downloading firmware using XperiFirm directly (not manually).

v5.6.1 [April 5, 2021]:
- Sony's server has discontinued support for obsolete security protocols (SSL, TLS 1.0/1.1) and requires TLS 1.2+ support. However, .NET Framework 4.0 only supports SSL and TLS 1.0, thus XperiFirm is now targeting .NET Framework 4.6, which means Windows XP and Vista (incl. SP1) can no longer be supported, and a minimum of Windows Vista SP2 is now required, and .NET Framework 4.6 (or newer) must be installed.

v5.4.0 [June 25, 2019]:
- FIX: Fixed unpacking while using Mono for Linux.

v5.3.8 [January 11, 2019]:
- FIX: Fixed "firmware is not available" error for certain firmware that are now hosted on a new Sony server.

v5.3.7 [July 28, 2018]:
- FIX: Workaround for broken version naming for certain Xperia XZ2 firmware.

v5.3.6 [March 2, 2018]:
- FIX: Fixed a reported cosmetic bug.

v5.3.5 [March 1, 2018]:
- FIX: Unpacking is matching that of Flashtool: the "partition.zip" is being extracted and a "partition_delivery.xml" is being properly created.

v5.3.1-v5.3.3 [March 1, 2018]:
- FIX: Bug and regression fixing for 5.3.0.

v5.3.0 [March 1, 2018]:
- NEW: Supports downloading official OTA packages (*.pkg). This can be enabled/disabled through "Settings". Those are single-file packages, thus Resuming is not supported, but you can still download them manually if you have to.
- FIX: A bunch of internal tweaks.
- MINOR: Larger device images.
- MINOR: Instructions for Manual downloading slightly changed: Folders should be named "FILE_<fileid>" instead of just "<fileid>".

v5.2.0 [October 21, 2017]:
- NEW: Manual mode is back, completely reworked for Sony's new API. Just click "Manual" and follow the instructions. No file renaming is required.

v5.1.0 [October 16, 2017]:
- NEW: CDF lists are now loaded directly from Sony servers. Manual updating is no longer needed, except for adding new devices, which is a rare case anyway.
- MINOR: Fixed support for Windows XP, but may be unstable as it uses a normal HTTP connection rather than a secure one.
- MINOR: Settings: "Unpack firmware automatically" checkbox - due to the demand.

v5.0.0 [May 16, 2016]:
- NEW: Download management, including a download queue that's saved on your computer and loaded on launch.
- NEW: Resuming feature, including checksum verification and automatic re-download of incomplete/corrupted chunks. Just click "Start" and the download will attempt to resume (for large firmware, the resuming might take a while).
- MINOR: Better error handling and prevention.
- MINOR: Settings: "Play a sound when a download completes"
- NOTE: "Manual" button and "Unpack automatically" are both obsolete, thus were removed in this version. Firmware will always be unpacked.
