### Grouping

24
25

In some situations, a phone farm such as BBK Electronics (now split into Vivo and Oppo) may have multiple phone brands under its belt. If the unlocking process or technology stack is similar, the companies can be grouped together: Oppo and Realme (BBK, using the same OS), Vivo and IQOO (BBK, but using a different OS).

Companies that do not allow unlocking must go to "⛔ Avoid at all costs!". Sometimes, while it's possible to unlock, the process can be so complicated that a company will be recommended to avoid. (See: Realme, Xiaomi)

### Brief History

If the company allowed unlocking in the past, or had different unlocking methods, it may be useful to devote a paragraph to a historical review.

The main focus of this list is bootloader unlocking, but other related topics may also be mentioned. It's best to mention them in one sentence and link to a source, rather than explaining them at length.

Related topics include, but are not limited to: rooting, custom operating systems, ADB.

### Images

44
44
+
It's fine to use images in brand pages, but they should have descriptive alt text and be small. The smaller size can be achieved by converting your images to lossy `.webp`.

45

46

Also, avoid using the markdown `![]()` syntax as it does not have a way to set `width` and `height` of the image.

       ### Huawei/Honor

     

       26
       26
       -
       In the past, Huawei allowed you to unlock with a special code you get by submitting some information to emui.com (IMEI, serial, model, and product ID), but in 2018 "corporate values have changed" and the site went down. <br/>

     

       27
       27
       -
       Worse, on Android 10+, the unlock command has been **completely removed** from fastboot.

       36
       36
       -
       In the flaming pile of HMD's "great" decisions to improve Nokia, one stands out more than others: They decided to follow the fresh "lock the bootloader" trend.<br/>

       The most annoying thing about them is that you *can* unlock your bootloader, but only if you can get into fastboot. And guess what? They locked fastboot with an RSA key!

       As per Realme, they decided that segregating people by ~~race~~ their phone's region is cool. If you didn't buy your phone in China or India, chances are you won't be unlocking anything anytime soon.

       In April-May 2023 you could unlock any Realme phone using this script [rmx3474-rooting](https://github.com/turistu/rmx3474-rooting), but on May 26th Realme posted this joke of an announcement on their forum [c.realme.com](https://c.realme.com/in/post-details/1671137365285982208). (They've deleted the original announcement)

     

       66
       66
       -
       Since then, they have forced their servers to only return "new struct" keys, which have model data attached, making the script useless.

       In theory, if available, you could use full-OTA packages to change your phone's firmware region and use the deep testing app directly, but I can't verify that this works (please, correct me if I'm wrong).

       As for China and India... Seeing how easily Realme dropped the ball on their global users, I personally would be worried about their future plans. For now, you'll have to find and follow device-specific instructions at [c.realme.com](https://c.realme.com/in/). The process is pretty much the same for most phones, but newer models may require a HeyTap account.

       While this (currently) only affects users in China, Xiaomi's new policy makes unlocking very annoying.

       And here's a list of things you have to do to get that:

     

       78
       78

       - You must be a citizen of China.

     

       79

       - You have to submit at least 1 HyperOS suggestion per month. (????)

       Additional BS applies:

     

       84
       84
       -
       - The permission to unlock is temporary and is granted for 1-year only.

     

       85
       85
       -
       - You can only unlock 3 devices per-year.

     

       86
       86
       -
       - You will not receive OTA updates.

     

       87
       87

       - your warranty will be void.

       For example, unlocking will permanently trip Knox. As a result, *any* Knox-based features will be broken *even if you re-lock*. This includes, but not limited to: Samsung Pay, Pass, Flow, Health, Secure Folder, Secure Wi-Fi, Smart View. Can you be denied warranty? Probably...

     

       107

       In the past, LG had a developer portal which could be used to unlock phones on their website, however it only supported international models of their phones, but in December 2021, LG announced the developer portal would be shutting down due to LG ending production of all phones. On some models (such as the Stylo 3 Plus and G6), the bootloader can be unlocked via `fastboot oem unlock` **only if** [the phone is a T-Mobile model.](https://xdaforums.com/t/unlock-bootloader-tmo.3578099/)

       In the past, HTC allowed you to unlock your bootloader on their [developer website](https://www.htcdev.com/bootloader), but in June 2018 for whatever reason, HTC announced that any new phones would not have unlockable bootloaders, however their developer website would remain up for older devices.

       HTC had a system known as "S-ON/S-OFF", with S-ON enabled, [the only partitions that can be flashed are system and recovery](https://www.htcdev.com/bootloader/about_unlock_process), all other partitions are read only. While HTC claims you can write boot with S-ON, it's complicated. For whatever reason, HTC made it so you can't flash boot.img from recovery, if you want to flash boot.img, you have to flash it in fastboot, meaning if you want to flash a ROM, you have to install it in recovery, then reboot to fastboot and flash boot.img, then you can boot. There have been systems to work around this, such as TWRP's [HTC Dumlock](https://xdaforums.com/t/htc-dumlock-flash-boot-from-recovery-without-fastboot-updated-2012-02-28-v2.1509743/). There are ways to achieve S-OFF, but it's different for each device. Search for your specific device on [XDA](https://xdaforums.com). Do note that due to the age of most of these tools, they may require legacy operating systems such as **Ubuntu 14.04 or Windows 7**.

       They've never had unlockable bootloaders, and although there are a number of unofficial methods. Some Snapdragon devices have a [FRP exploit you can use in EDL to unlock](https://github.com/sukanka/MEIZU16S_unlock_tutorial/wiki/FRP-Method), If your device is unsupported by the FRP exploit and isn't supported by mtkclient, there are [paid services](https://github.com/sukanka/MEIZU16S_unlock_tutorial/wiki/Unlock-Bootloader) which you can use at your own risk.

       Asus originally allowed you to unlock your bootloader via their website, however in November 2023, the website went down "for maintanence", Asus claimed it would come back, but it never did. Someone eventually found a way to unlock the bootloader on the Zenfone 9, and Asus responded, not by finally bringing the site back, but by [patching the method and introducing anti-rollback](https://www.reddit.com/r/zenfone/comments/19f4ny3/asus_now_actively_sabotaging_attempts_to_unlock/). Following Asus's false claims of a bootloader unlock eventually coming back, a UK customer sued Asus for a refund of their phone, [and Asus lost.](https://www.androidpolice.com/asus-removed-bootloader-unlock-from-phones/) Asus is still claiming the unlock site will come back eventuallly, but considering how long it's been closed, the anti-rollback, and them losing a lawsuit over their unlockable bootloader claims, it's safe to say it'll probably never come back.

       Asus originally allowed you to unlock your bootloader via their website, however in November 2023, the website went down "for maintanence", Asus claimed it would come back, but it never did. Someone eventually found a way to unlock the bootloader on the Zenfone 9, and Asus responded, not by finally bringing the site back, but by [patching the method and introducing anti-rollback](https://www.reddit.com/r/zenfone/comments/19f4ny3/asus_now_actively_sabotaging_attempts_to_unlock/). Following Asus's false claims of a bootloader unlock eventually coming back, a UK customer sued Asus for a refund of their phone, [and Asus lost.](https://www.androidpolice.com/asus-removed-bootloader-unlock-from-phones/) Asus is still claiming the unlock site will come back eventuallly, but considering how long it's been closed, the anti-rollback, and them losing a lawsuit over their unlockable bootloader claims, it's safe to say it'll probably never come back.

       All Fairphones after 2 require you to request a code from [this](https://www.fairphone.com/en/bootloader-unlocking-code-for-fairphone) website to enable OEM unlock.

       In the past, HTC allowed you to unlock your bootloader on their [developer website](https://www.htcdev.com/bootloader), but in June 2018 for whatever reason, HTC announced that any new phones would not have unlockable bootloaders, however their developer website would remain up for older devices.

       HTC had a system known as "S-ON/S-OFF", with S-ON enabled, [the only partitions that can be flashed are system and recovery](https://www.htcdev.com/bootloader/about_unlock_process), all other partitions are read only. While HTC claims you can write boot with S-ON, it's complicated. For whatever reason, HTC made it so you can't flash boot.img from recovery, if you want to flash boot.img, you have to flash it in fastboot, meaning if you want to flash a ROM, you have to install it in recovery, then reboot to fastboot and flash boot.img, then you can boot. There have been systems to work around this, such as TWRP's [HTC Dumlock](https://xdaforums.com/t/htc-dumlock-flash-boot-from-recovery-without-fastboot-updated-2012-02-28-v2.1509743/). There are ways to achieve S-OFF, but it's different for each device. Search for your specific device on [XDA](https://xdaforums.com). Do note that due to the age of most of these tools, they may require legacy operating systems such as **Ubuntu 14.04 or Windows 7**.

Some Snapdragon devices have a [FRP exploit you can use in EDL to unlock](https://github.com/sukanka/MEIZU16S_unlock_tutorial/wiki/FRP-Method), If your device is unsupported by the FRP exploit and isn't supported by mtkclient, there are [paid services](https://github.com/sukanka/MEIZU16S_unlock_tutorial/wiki/Unlock-Bootloader) which you can use at your own risk.

       The most annoying thing about them is that you *can* unlock your bootloader, but only if you can get into fastboot. And guess what? They locked fastboot with an RSA key!

       As per Realme, they decided that segregating people by ~~race~~ their phone's region is cool. If you didn't buy your phone in China or India, chances are you won't be unlocking anything anytime soon.

       In April-May 2023 you could unlock any Realme phone using this script [rmx3474-rooting](https://github.com/turistu/rmx3474-rooting), but on May 26th Realme posted this joke of an announcement on their forum [c.realme.com](https://c.realme.com/in/post-details/1671137365285982208). (They've deleted the original announcement)

     

       11
       11
       +
       Since then, they have forced their servers to only return "new struct" keys, which have model data attached, making the script useless.

       In theory, if available, you could use full-OTA packages to change your phone's firmware region and use the deep testing app directly, but I can't verify that this works (please, correct me if I'm wrong).

       As for China and India... Seeing how easily Realme dropped the ball on their global users, I personally would be worried about their future plans. For now, you'll have to find and follow device-specific instructions at [c.realme.com](https://c.realme.com/in/). The process is pretty much the same for most phones, but newer models may require a HeyTap account.

       For example, unlocking will permanently trip Knox. As a result, *any* Knox-based features will be broken *even if you re-lock*. This includes, but not limited to: Samsung Pay, Pass, Flow, Health, Secure Folder, Secure Wi-Fi, Smart View. Can you be denied warranty? Probably...

       Umidigi phones are generally unlockable, however due to them being a budget-focused manufacturer, they use Unisoc SoCs, and [Unisoc requires a bunch of extra steps to unlock for whatever reason](https://www.hovatek.com/forum/thread-32287.html), and therefore I wouldn't consider them completely safe. MediaTek Umidigi devies can just use flashing unlock/oem unlock in fastboot.
