[Q] Bricked Sony Xperia S - Help a noob out!

Hi all,
The wi-fi connectivity on my Sony Xperia S died a few days ago and it's been irritating me so I decided to root and upgrade to JB to see if that would sort it. Unlocked the bootloader, no problem. Rooted the phone, no problem. But then CWM couldn't identify my device and wouldn't install Recovery. I decided installed Flashtool and flashed a stock kernel, and now it seems like I have bricked the phone.
When I boot I get the Sony splash, and the Fastboot (blue) LED which then goes out leaving just the Sony splash. Pressing the volume keys does nothing during Fastboot. I can do a hard reset and get the three vibrations, but the boot loop is just the same when I power on again. In this state Flashtool says the following:
1/039/2013 14:39:48 - INFO - Device connected in flash mode
11/040/2013 14:40:32 - INFO - Device disconnected
11/040/2013 14:40:37 - ERROR - Drivers need to be installed for connected device.
11/040/2013 14:40:37 - ERROR - You can find them in the drivers folder of Flashtool.
Naturally trying to install the drivers does nothing.
Anyone got any suggestions? I really don't want to have to fork out for a new phone!
Cheers.

Make sure you have closed PCC & SUS.
Then try to flash again.

As cities516 has said, first make sure that all those Sony services and update programs are completely shut (be sure to check the status bar near the time and date too). When you power on your phone, the blue led blinks for some time and then fades away. This blue led does not indicate that you are in fastboot mode. So here is what you must do:-
1) Press and hold the volume up + power button until you get 3 vibrations.
2) DO NOT START THE PHONE.
3) Prepare flashtool to flash the stock ics ftf file
4) When it prompts you to connect your phone, hold the volume down key and connect the USB cable.
5) A green led should light up and the flashing process should begin.
6) Once the flashing is complete, disconnect the phone and turn it on normally.

That's great stuff, thanks. All working now! Although I do feel like a moron, I hadn't realised that the PCC was open in the system tray!

[Q] Stuck on sony logo

Hi,
My phone is stuck at sony logo, after install a custom rom (RomAur). I have locked BL, and I put my phone into fastboot mode and im tryng to fix it with flashtool (pc recognize the phone). Can I flash a rom in fastboot? it doesn´t work into flashmode. Any help? (As you can see im new in this topics...)

Did you try download stock ftf - run flashtool - choose the ftf, when ask for the phone ... push the off button for 5s (behind the phone next to sd slot), then put the phone in flash mode (vol. down) - connect your usb, phone should flash.

Every ZL/Z is meant to work in Flash Mode, just reset the phone by holding the OFF button on the back panel where the SD-card and SIM card are placed. Disconnect your phone from the computer, hold the OFF button until it vibrates THREE times (hold it for 3 seconds it vibrates twice (hard restart), hold for 5 it vibrates thrice(forced flashmode)) soon after plug in the phone into your computer (along with the proper drivers installed from Flashtool in (or wherever you installed it) C:/FlashTools/Drivers (these drivers are SOE-blah, ADB, and fast boot mainly located at the bottom.) Once you've accomplished this, head on over to the Android Development section download a FTF file and restore. If you wish to keep all your data try reinstalling RomAur with proper installation instructions, due to my lack of experience with that rom I cannot give you the best advice other than if you have CWM installed it's an option to constantly flash other roms/zips to possibly fix your scenario. Good luck!

I'll give you more details now, about my problem.
1.- My phone was OK (rooted and with CWM) running Hackit custom rom.
2.- I install RomAur, then on reboot the phone got stuck on sony logo (it means, sony logo, and then reboot, sony logo and then reboot, infinite loop). Pressing OFF button (back next to the SD) it restarts the phone but the infinite loop continues.
3.- I installed flashtool (drivers, etc)
4.- I run the phone and then pressing VOL DOWN and plugin the usb cable at the same time it puts on yellow light (i dont know what mode it is). Infinite loops stops, phone is off and battery charging icon is displayed.
5.- On yellow light then i disconnect the phone and then pressing VOL DOWN and reconnecting flashtool recognize it ("28/024/2013 20:24:13 - INFO - Device connected in flash mode"). No light on the phone. If i do the same but with VOL UP it runs fastboot (blue light).
6.-On flashmode, I press the flash device button (black beam icon), it ask for mode, i choose flashmode. Then i select the ftf. and flashtool displays
28/043/2013 20:43:29 - INFO - Preparing files for flashing
28/044/2013 20:44:07 - INFO - Device disconnected
And the infinite loop returns...
If i pressthe powe off button nothing happens, it vibrates only one time, every restart on the loop
HELP! and thanks for your answers

From your comments, get to your step 5. Meaning get your phone off. Run flashtool choose stock ftf when it asked for the phone. Holding Vol.Down plug in usb - this should reset your phone and get you going.

Story:
Just received Sony Smartwatch 3 and decided to oem unlock for future so once root available I would not need to reset device.
Enabled adb
manually specified correct drivers in device manager
rebooted to bootloader using adb reboot bootloader
entered fastboot oem unlock twice and watch rebooted
but got stuck on boot for whatever reason.
I tried all the methods to get into fastboot (Swiping diagonal as on LG watch, and together with power button as on samsung ) to no avail.
The only other mode I was able to get into - s1 flash device w/o drivers.
Found Sony Emma software to work with unlocked Xperia, and after its installation it said that bootloader is locked and I need to either update from sony site or unlock bootloader first!
Installed Sony PC Companion software, but software update while listing smartwatch 3 said that there is no firmware for it.
After googling random forums on bootlooping sony xperias found that to reset device you need to click "repair my phone/tablet" in Phone/Tablet Software Update section

Guide to unbrick bootlooping SWR50 that is able to get into s1 bootloader/flash mode:
1. Power off device by holding power key until it reboots and then switches off with few vibrations
2. Connect to computer and check device manager - you should see unknown device
3. Install Sony PC Companion from this website http://www.sonymobile.com/us/tools/pc-companion/
Check if driver appeared in the Device Manager, e.g. unknown device will disappear and something like SEFLash will appear under usb controllers
If driver is still not found - try to install Emma (http://developer.sonymobile.com/services/flash-tool/) and get this driver to work
4. Go into PC Companion and click on "Support Zone", it will be downloaded
5. Then click on "Accessories software update" and try to update Smartwatch 3 (We might get new versions in the future, so it will be easiest to do so)
UPDATE: Now you can reflash from Accessories page, it will ask if you want to refrlash. Keeping steps bellow for information purposes.
6. If #5 not working:
Click on "Phone/Tablet Software Update" (yes, silly), click on "repair my phone/tablet", click Continue and Agree to all licenses, etc....
7. Once presented by the list of phones - Select anything I guess, but I selected Xperia Z2, it should start downloading and then updating.
8. Once done it will say build number watch was flashed, in my case it was KNX01V
9. Disconnect watch and boot it.
P.S. I guess they show phone selection just to provide instructions how to get into download mode and then flash based on the versions from bootloader.
P.P.S I'm glad I tried this last resort thing after being ready to deal with verizon support and waiting for new watch...

I've found that formatting cache and userdata partition like it says in the link below makes the device boot as expected:
source.android.com -> /source/building-devices.html#unlocking-the-bootloader
(sorry for faulty link, new user)

Good to know, I decided to wait a bit as I was eager to play with new toy.
Will unlock tomorrow if it is still locked after Sony reset.
And looks like I would have to write my own apps to test GPS and sensors performance.

And the good news is fastboot state unlocked after stock reflash.

Can you please elaborate on which driver you used to get access to the Smartwatch 3 via ADB? I am trying to use the latest google USB driver, but the device is showing up as offline listed under "adb devices". Just tried the latest ADB v1.0.32 and it seems the watch shows up as "unauthorized". Did you see an ADB notification on the watch that you had to accept, because I am not seeing anything like that.
NVM, it started working after I restarted adb server like 25 times...

Device offline usually is not about driver. But I hit on device and manually picked google-adb composite device

OK, bricked watch today with corrupted /system and boot process hanged with non responsive power button. Had to wait for discharge and it was pita to get into flashmode with enough juice, because after black screen charging it boots instead of going into kernel charging.
Anyway it is up and running and has ROOT now!
Will upload files and create guide as soon as I will be with good internet.

See my sig!

Well, there are different levels of bootloaders
At least Sony s1 flash, fastboot, kernel...
To flash with PC companion you need to boot into s1 by powering off and then hold power and connect to USB once sony logo shown (you should see black screen with backlight on). Make sure you sit on PC companion update screen and that watch had enough juice.
With charging there are different levels of charging:
1. Battery dead
2. Boot loader charging (about 4 min from USB port) with black screen
3. Kernel charging either offline (if you powered off before) or boot and operational charging.
When #2 charges it will boot kernel and if kernel or system is broken it might hang and discharge.
But you can force into s1 flash mode before it boots into kernel. Or if you lucky you could power on and power off before it boots and hang.
In my case I had not enough juice to flash it and watch didn't react to button in kernel mode, so I had to wait for discharge, then plugged into USB and start timer, figured it boots after ~3min 55sec. So I opened PC companion update screen, waited 3:53 and disconnected watch, then hold power button and connect to PC after 5 sec and was able to flash.
To power off - just hold power button until it reboots and continue holding until it vibrates 3 times.
Good luck

This method is windows only. Is there no cross-platform way to do it?

I did the stupid thing.. and ended up with a softbricked phone.
Sony PC Companion did the trick for me!
I tried doing it through VMWare on my macbook, but didn't seem to work at all.
On windows it was plug'n'Pray

Sony companion will not let me restore my SW50. Detects it and tells me that the software is updated. If I try from the menu to repair phone, it makes me accept all agreements and finally tells me the same thing no updates.
Is in bootloop and do not start after open bootloader

My sw3 is in bootloop.I uesd your guide but still can't repair my watch. I tried many time to use pc companion but always got the same wrong message,wrong code(100) which couldn't connect to the Internet.

@swidon @KONG8691

Thanks for your help

Yes!, follow these instructions and you can enter in fastboot or recovery and flash a new firmware:
Detach any USB cable connected to the watch
Turn it off holding the power button and keep holding the button until the watch vibrates three times and then switches it off
Press the power button and keep holding. A blue screen that prompts to insert an USB cable will display
Double tap the power button
A black menu will display, with on-screen instructions
Move to Fastboot or Recovery Mode pressing the power button, once a time
Select Fastboot (or Recovery) by double pressing the power button
Good luck bro.

Z1C Overheating - unable to boot / charge

Hi guys,
I have been "gifted" by broken Xperia Z1C and I'm trying to fix it.
The issue is that when I try to power on, it's trying to boot, but it will turn off during blue animation, not sure if it's boot logo. However, when I try to charge the phone, it will show
"Your device turned off due to overheating. Charging will continue after the device has cooled down." and as you supposed, it will never happened.
I have tried:
- hard reset by volup + power button
- reset with red button near sim card
- xperia companion repair - result: successfully repaired, but nothing happend to device
- flashing older firmware D5503_14.5.A.0.270_Generic BAL.ftf using Flashtool - successfully but nothing happened
- some magic commands with fastboot.exe, nothing happened
Then I have tried to change battery from another Z1C, device is not responding on power on button (just 3 times red led blinks after charger connected) . Then I have put back the original battery to broken device, same overheating issue.
Now I think it's hardware issue, or do you have any ideas? Why another battery don't works?
Thanks

[UPDATED] Recover from Hard Brick and QFIL guide through bootloader.

This guide is to recover the Zuk Z2 (plus) from hard brick state
So you might be stuck here -
Phone is not turning on
Phone Reboot and screen go black with notification light on and you are unable to switch it off.
How To-
1. How to switch it off
- First this is happening because you have locked you're bootloader
- You have black screen and led on so just hold power button then Zuk logo will be flash after that you will get black screen again and the phone is preparing to reboot but before that the led will get turn off immediately release power button.
(It's crucial timing but when rebooting your device vibrates so it's the time when phone is about to start vibrate while LED is off just leave power button)
- You have it Your phone is switched off
(Tip- Let it reboot once after that don't leave the power button and after that led will get off you have to remove finger from power button this is tricky )
2. Going to Bootloader
-First connect the USB to laptop
-After you have switched off your phone press volume up and down together and with holding buttons connect the phone to USB and you will see the fastboot mode.
3. Unlock your phone
-Remember the unlock bootloader file in your email re download it and unlock your bootloader again
- Don't reboot right away as you don't have any OS installed Even if it boot it might give problem.
- after unlocking phone you will see phone rebooted press power button reboot press volume the volume button and go to reboot option
4. For Userdata
- I suggest you to flash recovery instead of using old installed one.
- go to fastboot and flash the TWRP.
- Boot into TWRP and you will see your data on internal storage is present so just sideload ROM or if you have in internal storage just flash
( Note- in case you are using TWRP 3.4 newer roms with factory based ROM will flashed without problem in case you are trying to flash old Oreo non-treble ROMs you need to wipe like you do for normal ROM installation and reboot to recovery then flash Oreo Non-treble ROM otherwise they will not boot even after flashing)
Or
- QFIL ZUI 4.0.199ST as this QPST
- When selecting the XML file select retain userdata one so it won't erase your userdata partitions
5. In case you want to flash ZUI
- Load files in QFIL
- To reboot phone into EDL from Fastboot mode type following command
Code:
fastboot -i0x2b4c oem reboot-edl
- It will get detected in QFIL just hit Download.
In case you run into Sahara failed error follow my guide to fix sahara error

Hey I have a hardbricked zuk but the only signs of life is a white led and at times a vibration when I connect it to pc there is a a port written as Qualcomm HS-USB Diagnostics 900E (COM4) . I've seen quite a lot of threads of booting it to edl and deep flashing is not a choice I'm willing to take . I'd appreciate it if you are able to help me

thanks
Thanks a lot buddy.
Bricked today by flashing a baseband.
Revived as per your guide.
Actually i'm never tensed about flashing roms, Kernels, fonts, apps, mods anything and bricking our device.
There are so many good guys to save our a$$...................
Thanks buddies....... :good::good::good::good:
