How to Boot Into Sony Xperia U Fastboot Mode

XPERIA U FASTBOOT MODE

• Using Hardware buttons
• Using ADB (Android Debug Bridge)
• Using QuickBoot App

What is Fastboot?

Fastboot allows you to re-flash partitions on your Android device. It works through PC command line and connects over a USB connection with your device. Not every Android device manufacturer allows Fastboot access to end-users, but thankfully Sony does allow it.

On Sony Xperia devices you can unlock the bootloader using Fastboot and then flash/modify system or recovery images or completely wipe device’s data easily using the command line on your PC.

Also, if you ever come across the term ‘Bootloader mode’ than know that it’s the other name of Fastboot mode. Both these modes are one and the same thing.

There are multiple methods to boot your Xperia U in Fastboot mode. The most handy (and hardware coded) method is about pressing a particular hardware button while connecting the device to PC . Others are software based, let’s have a look at them below.

1) Boot into Xperia U Fastboot Mode Using HARDWARE BUTTONS

This method is a fail-proof method that’ll always work for you, unless you’ve broken one of hardware keys. In such a case you’d be left with only the other two methods discussed on this page.

• Switch off your Xperia U first
• Press and hold the Volume Up button
• Connect to your PC using a USB Cable while holding down the Volume Up button on your Xperia U
  └ Before plugging in the USB cable on your Xperia U make sure that the other end of USB cable is already connected to the PC.
• Your Xperia U should be in Flash Mode now and the device’s LED light should turn into Blue

2) Boot into Xperia U Fastboot Mode Using ADB

ADB stands for Android Debug Bridge, a tool used to send terminal commands to a Android device via a PC command line. ADB requires a bit of setup, but it gets the job done with much lesser effort than hardware buttons, so pretty useful in cases when you’ve to boot into Fastboot Mode frequently. Also, if (for some reason) your hardware buttons aren’t working than this is a very good alternative to boot into Fastboot Mode.

First off, DOWNLOAD ADB FILES →

And make sure you’ve proper drivers installed for your device.

• Extract the file (ADB files for Fastboot Mode.zip) you downloaded from the link above to a separate folder on your computer
• Prepare your phone
  • Enable developer options: Go to your phone’s Settings » select About phone » Scroll to the bottom and tap on “Build number” seven times to enable developer options
  • Enable USB Debugging: Open phone’s Settings » select Developer options » Tick the “USB debugging” checkbox (under Debugging section)
• Connect your phone to PC with a USB cable and if/when a pop-up screen shows up on Phone asking you to ‘Allow USB debugging?‘ for the computer, make sure you tick the checkbox and tap OK
  
• Open the folder where you extracted the files and double-click/run the ‘Boot into Fastboot Mode.bat‘ file to reboot your device into Fastboot Mode
  └ If the script shows any error than that means either your device is not connected or you don’t have proper driver for your device installed on your PC.

For your information, the ‘Boot into Fastboot Mode.bat‘ script file that we used above to boot your device into Fastboot Mode only uses one line of command:

adb reboot bootloader

If you already have ADB setup on your computer and you know how to use it, then you may just use the command given above to boot into Fastboot Mode.

3) Boot into Xperia U Fastboot Mode Using Quick Boot (Reboot) APP

Yes! There’s an app for rebooting your phone into Fastboot Mode, and it’s the most easier of the methods we discussed above. But it won’t work unless you’ve root access on your Xperia U, and since not everyone roots their device, we’ve put this as the last method here.

ROOT ACCESS REQUIRED

• Install the Quick Boot (Reboot) app from Play Store on your Xperia U  |  Play store link →
• Open the app and grant Root Access
• Select ‘Bootloader‘ from the list of options and it’ll boot your device into Fastboot Mode

That’s all.

On the bottom-left of the back cover, there is a strap hole in there. This strap hole also has another function for opening the back cover case. This strap hole is the first start as a opening key of the cover. Here the tips for you to open the cover.

Just align the cover casing with the body (make sure the camera hold is aligned with the 5 Megapixel rear camera) then press the cover down until it's attached and locked. You might hear a "clack" or "creek" sound when you do this. Do it, side to side. Mak sure there is no remind gap between the cover and the body of the phone. Done.

Eject Card holder, Insert SIM Card on Sony Xperia Go ST27i / ST27a

After you removed the back cover case, now you can insert your SIM card. The Sony Xperia go uses standard SIM card type, but you can't directly insert the SIM card to its card slot. It's because the card need  to be placed first on its SIM card holder (card tray). Therefore to be able to insert the SIM card, you had to eject the card holder from its slot. With your fingernail (forefinger) pull out the SIM card holder from its slot. The card holder slot provide on the left side of the phone (from front panel view, see the image to make sure where the location of this card holder slot).

Place the SIM card to its holder and make sure that the gold-colored contact is facing up. Make sure that the cut-edge also align properly with the card holder, then you can insert the card holder (with the SIM card had already in) to the card holder slot. Done.

Insert Memory Card on Sony Xperia Go ST27i / ST27a

To insert the microSD memory card, you need to open the back cover casing (just like on SIM card), but at this time, even though you had removed / opened the cover, there is an additional protection on the external memory card slot. It has a special cover. This microSD card slot cover is applied to attain the IP67 certificate on dust and water proof. With the Xperia go rear panel facing up, you can find the location of this microSD slot with its cover on the top-right side of the phone (picture). There is a small gap on the cover of the slot, use this gap to pull out the cover using your finger nail. Insert your fingernail (forefinger) between the gab and pull it out. Then you are ready to insert your memory card (up to 32GB capacity).

With gold-contacts facing up, and it align properly (there is a picture carved tutorial above the microSD slot that you can follow), push the microSD card into its slot until it locked. Use your fingernail (or the side of SIM card or similar thing -- nail cutter for example) to press the card until it reach the end of the slot and locked. Then the final step should be place the cover back to its position until it's fully latched. Done.

Doing Hard Reset aka Factory Reset on Sony Xperia go ST27i / ST27a and Charge the battery.

If you owned this 3.5 inches phone for the first time and you wanna turn the phone on (by pressing the power button until it vibrates) for the first time after you had been assembled all the part (SIM, microSD memory, and else), you need to charge for at least 30 minutes the battery of this Xperia go. FYI, the battery is unremovable and replaceable type. This must be one of the reason to acquire the IP67 certificate. That is why there is no tutorial on removing and assembling the battery for this device. It uses Li-ion type with 1305 mAh capacity.

Turn Sony Xperia go On, Do Reboot on ST27i / ST27a

To charge the phone all you need to do is connecting the microUSB port with your phone. The USB port for charge had a cover that you need to open first. Use your finger nail to open it. On the other end of USB plug the USB port into Power Adapter then finally plug the Adapter into Power Electricity Source in your Home. Done. Otherwise, you can directly connect the USB cable into Personal Computer. Though, we not recommend this charging option if it purposely for the first time of battery charging. It may take a little longer than via Power Adapter.

To do Factory Reset aka Hard Reset all you had to do just Go to Settings > Tab Privacy > Tap Factory data reset > Reset phone > Erase everything. But, in case you just wanna reboot / restart the phone, you can follow this key hardware combination: Press and Hold the Volume button and Power button at the same time, then release it whenever the phone vibrate. This action sometime also called as Soft Reset.

In case you phone stop responding or touchscreen is frozen, you can turn off the phone by Holding and pressing the Power button for about 11 seconds, then wait until the phone vibrates 3 (three) times, and release the key. That would shut down the phone automatically: forced shutdown. If the freezing problem frequently occurred, you can do Factory Reset, but make sure all you data got saved first (back up needed).

How to Manually Repair Windows 7 Boot Loader Problems

If you’re having boot problems on your Windows PC, it’s often helpful to repair the MBR (Master Boot Record) to restore the Windows 7 boot loader—and you can do it easily from the Windows installation disc.

This is generally most useful if you’ve broken something and there’s a boot loader error, or if you have made the mistake of installing an older version of Windows on the same PC that already has Windows 7 which wipes out the boot loader.

Note: If your PC starts booting into Windows but fails, you should probably try using Safe Mode instead.

Boot From the Windows Install Disc

The first thing you’ll need to do is boot off the install disc, and then click through until you see the “Repair your computer” link in the lower left-hand corner.

You’ll need to choose the correct installation of Windows and then click the Next button.

And then you’ll get to the System Recovery Options screen, where you can get to the Command Prompt.

Repairing the Master Boot Record

If you want to restore the master boot record, you can simply type in the following command:

bootrec /fixmbr

You can also write a new boot sector onto the system partition with this command (which is often more useful):

bootrec /fixboot

And of course, if you just use bootrec /? you’ll be able to see all the options.

This is the same way that we fixed the “BOOTMGR is missing” error when trying to boot up Windows 7 or Vista.

Replacing the Windows XP Bootloader with Windows 7

If you’ve managed to install XP on the same PC that you already had Windows 7 on, you’ll noticed that you can’t boot into Windows 7 anymore. You can use this command to fix that and restore the Windows 7 bootloader:

bootsect /nt60 all

Depending on the partition that you’ve installed, you might need to substitute the drive letter instead of “all”.

Note: if you want to restore Windows XP back to the menu, you can open up a command prompt in Windows 7 and run this command:

bcdedit /create {ntldr} -d “Windows XP”

Using the Automated Startup Repair

Of course, all this command-line stuff is probably not necessary in most cases. You can usually just use the Startup Repair option from the Recovery menu…

It’ll check for problems and probably fix them. If not, then you can always use the command prompt.

Have you ever needed to restore your boot loader to get Windows working again?
