[GUIDE] Recover 2012 and newer XPERIAs from SOFT-brick...[GUIDE]

If you are not sure what your doing or just want to confirm something, PLEASE ASK QUESTIONS FIRST. You always want to do the easiest things first.There many of us that have had success using different methods. And there are many of us who are willing to help.

The Wikipedia definition for {Brick (electronics)}

When used in reference to consumer electronics, a "brick" describes an electronic device such as a smart phone, game console, router, or tablet computer that owing to a serious misconfiguration, corrupted firmware or a hardware problem, can no longer function. The term derives from the vaguely cuboid shape of many electronic devices (and their detachable power supplies) and the suggestion that the device can only function as a large, heavy object.
The term can also be used as a verb. For example, "I bricked my MP3 player when I tried to modify its firmware."[1]
In one common sense of the term, "bricking" suggests that the damage, often a misconfiguration of essential on-board software, is so serious as to have rendered the device permanently unusable.
However, another use of the term "bricked" is understood to describe a situation where a device is unable to function even when the device does have potential to be recovered later to a working state. In this sense, the damage may be reversible; it is only during the period that it's unable to function that the device is deemed "bricked". This is often referred to as a "soft brick" whereas an unrecoverable device is a "hard brick".

DON'T WORRY, BE PATIENT, YOU CAN FIX YOUR PHONE.



This common 'cents' is worth more than [strike]a million dollars[/strike] the price of your phone

For this guide I will define types of RESETS that happen when pressing both the POWER and VOLUME UP buttons.

SOFT RESET = 1 vibration then let go of buttons (hold about 3 seconds); Like hitting REBOOT.
HARD RESET = 3 vibrations then let go (about 10 seconds); Like taking out the battery.*
*USE HARD RESET ONLY IF ALL OTHER TRICKS HAVE FAILED. RECOVERY FROM THIS DEEP LEVEL OF SOFT-BRICK WILL TAKE A LONG TIME

Both can be used at anytime on a working phone. Most bootloops will also allow resets

XPERIA phones have 2 different modes that are used in recovering from SOFT-brick. FLASH mode & FASTBOOT mode.

FLASH mode, is used by FLASHTOOL and can be used on every model of XPERIA phone with a locked or unlocked bootloader. FLASH mode will give a soild GREEN notification led when connected. To connect in FLASH mode:

1. Start with the phone turned off (or in between loops for some tricks)
2. Press and HOLD the volume DOWN button. (don't let go )
3. Now connect to a PC using USB
4. If all went correctly you will get GREEN led, then let go of button

FASTBOOT mode is used by Android Debug Bridge (ADB), and is found on every Android device. FLASHTOOL also uses FASTBOOT mode, however to flash this way you need an UNLOCKED bootloader. NOT EVERY PHONE CAN USE FASTBOOT. To find out if you can use FASTBOOT and how to set it up read {}. FASTBOOT mode will give a soild BLUE notification led when connected. To connect in FASTBOOT mode:

1. Start with the phone turned off (or in between loops for some tricks)
2. Press and HOLD volume UP button. (don't let go )
3. Now connect to a PC using USB
4. If all went correctly you will get BLUE led, then let go of button

To recover your phone you need to have FLASHTOOL ready and waiting at a specific spot.

}

1. DO NOT CONNTECT YOUR PHONE
2. First you need to have FLASHTOOL installed from {HERE}
3. Now run FLASHTOOL.
4. From FLASHTOOL home, select the flash/lightning bolt button
5. Select FLASH MODE
6. Select your stock firmware file
7. WIPE: everything
8. If available EXCLUDE: TA. (this option is not available for all stock.ftf files, if it's there just exclude it)
9. Now click START button
10. After FLASHTOOL prepares files, you should get this screen (or similar depending on version of FLASHTOOL)
11. >>>>>STOP<<<<< FLASHTOOL is now ready for TRICKS

For help with finding your phones STOCK.ftf file click here

You can use the file for your XPERIA model below to recover from SOFT-brick.
To make your models specific .ftf file after you recover, you will find instructions {IN THIS POST}




MAKE SURE YOU USE A STOCK FIRMWARE FOR YOUR MODEL XPERIA. Each phone model has a different file. Using the wrong file will give you the very SOFT-brick your trying to fix. If your not sure then ask for help.

BATTERY CHARGING CYCLES

On a working phone there are different stages of a battery's charging cycle. The stages are listed in order they happen. The cycle goes from a completely dead battery through a phone running on battery and back to a completely dead battery.

1. Dead battery. No response from the power button, no screen and no led.
2. Connect to charger
3. low battery level charging mode. This is when just the RED led is on and no screen. At this stage the battery's charge is to low to turn the phone on, but it is charging.
4. Kernel controlled off-line charging mode. This is when the battery has charged enough from step (3) and boots the kernel to charge the battery. The phone is off, but could be turned on using the power button. A quick press of the power button will show this battery icon. Icon will fill with charge.
   
   The kernel also controls charging when the phone is on.
5. Battery is fully charged.
6. Unplug the phone and turn on.
7. Battery is dead from normal use.
8. Repeat stages starting at (1)

Now, that is for a working phone. But if your reading this you don't care about a working cycle right? WRONG, this gives a baseline of charging check points to help in recovering your phone, so it is fairly important to understand.
A soft-brick charging cycle can restart at different points along the baseline while attempting to boot.


The kernel is the first thing to run at start-up.
If the kernel is broken the phone may.....

• Lock-up before the kernel boot screen with just the back-light on.
• Lock-up at the kernel boot screen.
• get stuck in boot loops.
  The SONY screen is displayed during kernel start-up, for a stock kernel.
  A charging cycle for a phone with a broken kernel can go as far as stage (4) and then lock up or boot loop. Then the battery will have to die for the phone to reset and start over at step (1).

Thus ending a broken kernel cycle from dead battery to dead battery.


The system or ROM/firmware runs after the kernel starts successfully.
If the ROM is broken the phone may.....

• Lock-up after the kernel screen with just the back-light on
• Lock-up at the ROM boot screen
• Get stuck in boot loops.
  The XPERIA screen is displayed during ROM start-up, for a stock ROM.
  A charging cycle for a phone with a broken ROM can go as far as stage (6) and then lock up or boot loop. Then the battery will have to die for the phone to reset and start over at step (1).

Thus ending a broken system cycle from dead battery to dead battery.

AN UNLOCKED BOOTLOADER WILL NEED TO BE RE-LOCKED FOR PC COMPANION TO WORK.

Please read all of the first post above and then all the instructions FIRST, before trying anything. If you are unsure about anything PLEASE ASK QUESTIONS. No one wants you to damage your phone. So make sure you understand what your doing. If your not sure what your doing you could do more damage to the phone And remember with an unlocked bootloader you can do severe damage.

ATTENTION:

If your phone is not working but you see a led or have bootloops DO NOT USE HARD-RESET. This can make your phone lock/freeze up until the battery dies. It took 51 hours for mine to die.
However if you get stuck on a boot screen or get bootloops a SOFT-RESET may work to reboot.

If you have unlocked your bootloader this guide may or may not work for you. If you have trouble recovering then see the "TRICKS that require FASTBOOT-mode" below.

YOU NEED TO RESET YOUR PHONE!

If your phone is soft-brick and does nothing when, -the buttons are pressed, -a charger is plugged in, -or if the screen is still ON then....

• The memory chips need lose power to clear the bad data and reset the phone. Either by the battery going dead or by unplugging the battery.
  
  
• You can to leave the phone on a charger to see when the battery dies. Usually the battery will not charge in a soft-brick state and will die while still plugged in. After the reset you should then get the red led. However if you get a red led immediately when first plugged in and no response but red led for a long time, then you may need to leave the phone unplugged and let the battery die.
  
  
• Only after the chips reset will you get the red led. The RED LED should mean the phone is charging in 'low battery level charge mode'.
  
  
• Once you get the red led, after the reset, do NOT try to turn on the phone. If you try to start the phone now without fixing the problem you will have to start all over.
  

UNPLUGGING THE BATTERY

If you feel like taking your phone apart you can unplug the battery. Most 2012 XPERIA's have a built in battery that is not designed to be easily removed. However next to the battery there should be a ribbon cable with a plug to the mother board. Unplugging this cable for 2-3 minutes should reset your phone without letting the battery die.
CAUTION: this may effect your warranty

The Rubber Band Trick

Here are some links to help describe the rubber band trick.

[SIZE="5"]

Now after the phone has reset and you have the red led.

~ keep charging with wall charger. A charger has a higher current rate and should charge faster than a PC.

~ Make flashtool ready to flash your stock.ftf file. If you are experiencing errors while flashing the entire ROM try to flash just the kernel, check off all in the exclude box except kernel. At this point your battery is very low and doing this will make the flash process much faster than trying to flash the entire ROM.

~ Try to connect phone in flash-mode. If your phone has enough battery you will get green led. If the flash fails on the first try, just put it back on the charger and wait about 10-30 minutes and repeat. It may take a while to charge enough to flash.

~ If you see the red led go out, then try for flash-mode.

~ If you get bootloops, try to flash between loops. As soon as you notice loop, hold volume down and plug the phone into PC with FlashTool ready. Once the loop starts you have very little time to flash, before the loops drain the battery. If you can not flash, the battery will have to die and phone reset. Then start over with red led.

~ After you complete the flash, unplug the phone and see what happens. Sometimes it will boot to Sony screen and then shut off by itself, if so plug in to a charger. You should get the red led then the battery charging screen then. After about 20 minutes of red led.

~ If you get a green led (for flash mode) then press the power button until 1 vibration. The green led should flash 1 time. This will end flashmode and start the phone. If you don't end flashmode the phone will still give a green led whenever plugged in, but it will not charge, until the battery dies and the phone resets again.

~ If you were able to flash the entire stock.ftf file and your phone has gone from red led to the charging screen, then your phone should now be recovered and turn on normally.

~ If you could only flash the kernel then you will get bootloops. Again you can unplug and try a hard-reset to turn off the phone. If hard-reset works plug in charger and wait for red led and then charging screen.

~ If you don't do a hard-reset, the phone boot looping should kill the battery and then plug in charger (this is what I did). Then wait for red led and then charging screen.

~ Now you should have a good kernel and the phone plugged in. You should have the charging screen with the battery icon and led for 'off-line charge mode'. Charge until over 50%. A quick press of the power button will bring up the charging screen.

~ Once over 50% then flash the full stock.ftf with a full wipe.

~ If you got this far but still cannot flash a full stock.ftf file then try to use PC Companion software to REPAIR your phone. Make sure battery is more than 50%.

~ If all fails then post a copy of the FlashTool log in this thread.
