So you've bricked your phone. You flashed a ROM, installed a mod, tweaked a system file, or did something else---and now your phone won't boot.

Don't panic! It's almost certainly fixable. Here's how to lớn unbrick an game android phone.


What do the Terms 'Bricking' or a 'Bricked Phone' Mean?

'Bricking' your phone essentially means that your once useful device is now only as useful as a brick. A 'bricked phone' is usually unresponsive, won't nguồn on, and doesn't function normally.

The steps for how to unbrick a phone depend on how it's bricked in the first place. There are two categories of bricked phones:

The soft brick. The phone freezes on the game android boot screen, gets stuck in a boot loop, or just goes straight to lớn recovery. So long as something happens when you press the nguồn button, it's soft bricked. The good news is these are pretty easy khổng lồ fix. The hard brick. You push the nguồn button, và nothing happens. Hard bricks can be caused by issues like attempting to lớn flash an incompatible ROM or kernel, và there's normally no software solution for them. Hard bricks are terrible news, but fortunately, they're quite rare.

Most likely, you're soft bricked, và you'll see something like the image above. While the differences in how various devices work make it hard to come up with a catch-all solution khổng lồ unbrick Android, there are four common tricks you can try to lớn get yourself back on track:


Wipe the data, then re-flash a custom ROM Disable Xposed mods through recovery Restore a Nandroid backup Flash a factory image

Before you get started, make sure your phone & computer are phối up and ready with the proper tools.

What You Need lớn Unbrick an android Phone

Chances are, you already have most of the tools you need to unbrick your phone. They're the same tools you used to root your device & flash ROMs, so you should already be familiar with how they work. Even so, double-check before you begin.

Most important is a custom recovery. You likely installed this when you rooted your phone, but it can sometimes get overwritten by the stock recovery or wiped entirely. If you vì need lớn reinstall it, we recommend going with TWRP. It's a fully-featured custom recovery that's too easy to lớn use & has builds for most popular devices.


Next, you might need Fastboot and ADB. These are commonly used for rooting and flashing system mods, and you can get both from the android Developers website. Kiểm tra our primer on how lớn use Fastboot và ADB if you aren't familiar with them.

And finally, some manufacturers use special software to flash factory images. Hopefully, you can avoid doing this, but if you need to, you can use Odin for Samsung, the LG Flash Tool for LG devices, or the ZTE Unbrick Tool if you've got a ZTE device. Just make sure that they tư vấn your specific mã sản phẩm of device.

Most of these tools will let you fix a bricked app android phone using a PC. However, you can often vì the job directly on the phone itself.


1. Wipe Data và Re-Flash a Custom ROM

Try this method if: You flashed a ROM, & now apk won't boot.

One of the most likely causes of soft bricking your phone is when you have problems when flashing a new custom ROM. The culprit here is often that you didn't wipe your data first.

This is referred khổng lồ as a "dirty flash," and occurs when you choose to lớn forego the inconvenience of having khổng lồ restore your apps & data by flashing a new ROM on top of your old one. As a general rule, you can get away with it if you're flashing a newer version of your existing ROM, but you must always wipe your data whenever you flash a different ROM.

Fortunately, it's easy to lớn fix---as long as you've backed up your phone properly. If you haven't, well, you've learned an important lesson the hard way. Follow these steps:


Boot into your custom recovery. Navigate khổng lồ the Wipe option and choose Advanced Wipe. kiểm tra the box marked Data (you can wipe the system, ART cache, và cache again, too), then hit Confirm. Re-flash your custom ROM.

Wiping your data effectively performs a factory reset, but it shouldn't clear your internal storage or SD thẻ (although, again, you should back it up just to be safe). When you restart your phone, you'll see the Android cài đặt screen. After entering your Google trương mục information, your apps should begin reinstalling automatically.

If you need to, you can restore your data from your Nandroid backup. See the Restore a Nandroid Backup section below.


2. Disable Xposed Modules in Recovery

Try this method if: You get boot loops after installing a new Xposed module.

The Xposed Framework isn't as common as it once was, but it's still a simple way to mod your phone, và also one of the most dangerous.

The best Xposed modules are so easy khổng lồ install---many of them are available in the Play Store---that they lull you into a false sense of security. It's unlikely anyone makes a Nandroid backup before installing a new Xposed module, even though they can brick your phone.


Use ADB Push to Install the Xposed Uninstaller

The best way to khuyễn mãi giảm giá with these problems is with the Xposed Uninstaller, if it's available for your version of Android. This is a small flashable ZIP that you can install through the recovery to remove Xposed from your device.

If you don't already have it on your phone, you can put it on an SD card, or you might be able to copy it over using the ADB push method:


*

Connect your phone lớn your computer via USB & boot into recovery. Launch the command prompt (Windows) or Terminal (Mac) và use the cd command khổng lồ change the directory khổng lồ where you have adb installed. Type adb push . On Mac và Linux, precede the command with ./ (such as ./adb). When the tệp tin finishes copying, flash it through the recovery.

How to Disable Xposed Modules in Recovery

If you can't use ADB push & the Xposed Uninstaller, try either of these solutions.

This method lets you disable Xposed through recovery:

Boot into recovery, then navigate lớn Advanced > Terminal command. Create a file called /data/data/de.robv.android.xposed.installer/conf/disabled Reboot your phone.

This method prevents Xposed modules from starting:

Boot into recovery và select File Manager. Navigate khổng lồ the folder /data/data/de.robv.android.xposed.installer/conf/ then delete the file modules.list Reboot your phone.

None of these solutions will undo any changes the modules have made to lớn your system. If these changes caused your phone to brick, you will have lớn restore your Nandroid backup.


3. Restore a Nandroid Backup

Try this method if: You need to remove other system mods, replace a tweaked system file, or if the methods above didn't work.

The Nandroid backup is the safety net for apk mods và tweaks. It's a complete snapshot of your phone---not just your data và apps, but of the operating system itself. So long as you can access your custom recovery & have a Nandroid backup, you will be able to lớn get your soft bricked device up & running. To bởi so:

Boot into recovery và navigate lớn Restore. Select your backup from the list, confirm, và wait while it's restored. Reboot your phone.

Nandroid backups are a bit of a pain to make. They take a while & cannot be done in the background. But they're worth it: they're the simplest way to unbrick your phone.


Recover Data From a Nandroid Backup

A Nandroid backup can also save the day if you had to wipe your data & didn't back it up in an easily restorable form. It's possible lớn extract specific parts of a Nandroid, so you can restore your apps and data without needing to restore the operating system as well.

Here are the instructions for this:

Tap the menu button and navigate lớn Special Backup/Restore > Extract from Nandroid Backup. Select your backup from the list. Choose whether lớn restore apps, data, or both, and select them (or hit Select All). Tap the green tick icon to start the restore process.

4. Flash a Factory Image

Try this method if: None of the other options work.

If your attempts at unbricking app android have failed so far, the nuclear option is to re-flash a factory image. This restores the phone to lớn its original state và will wipe your internal storage as well as everything else. It'll also unroot your phone.


Because it wipes everything, you might be better off trying to flash a stock ROM first. OnePlus actually offers flashable ROMs for recovery rather than factory images, và you'll find similar for virtually every device at xda-developers.com. In many cases, you'll be able to flash a pre-rooted stock ROM for added convenience.


Where flashing a factory image differs from flashing a ROM is that it happens over a connection to lớn your desktop computer rather than through recovery. Some devices use the Fastboot tool from the android SDK, but others use custom software. Samsung uses the Odin tool, for instance.

Because of the different methods used, the instructions for flashing a factory image differ for each device. And not all manufacturers make their firmware publicly available, so you have to find them from unofficial sources.

Here's where khổng lồ find factory images for some popular android brands:


What About Hard Bricks?

Hard bricked phones are notoriously more difficult to lớn fix, but thankfully they're also much rarer.


How khổng lồ Unbrick a Hard Bricked app android Phone

First, make sure the phone really is bricked---plug it in & leave it charging for a while.

You may also want to try plugging it into your computer, you can be pretty sure that your phone is hard bricked if it is not detected by your PC.

If it is definitely hard bricked, then you may be out of luck. A few phones can be revived with a USB Jig, a tiny device that plugs into the USB port & puts the phone into download Mode lớn reinstall the stock firmware.


You can find USB Jigs for hard bricked phones for cheap on eBay, but only for a very small number of old devices. Even then, there's no guarantee that they'll work.

Beyond that, you may need khổng lồ send your phone in for repair (though rooting it might have voided your warranty) or seek out a local phone repair person. But you most likely will end up needing to lớn buy a new device.
