SGP311 Only Fastboot Mode - Xperia Tablet Z Q&A, Help & Troubleshooting

Hello
i flashed my tablet Z SPG311.
I made following steps:
-root
-unloock bootloader
-recovery
-installed Rom and Gapps (Lineagos)
Then I wanted to reboot the tablet but it wont turn on i only can go in fasboot mode.
When i am trying to go in to flashmode he red LED goes on and immidently off.
Also the PC says Unknow device. And it worked in the step of rooting.
I am sad about that I hope anyone can help me with this problem maybe a Kernel would fix it....
It would be nice if somebody can help me or can say me if it is dead for ever or I (we) can fix it again..
Thanks guys for reading it.
Best wishes

[Q] WT19i no reaction, no lights after flashing

Hello everyone,
please help me out.
I tried to flash a custom rom on my sony ericsson live with walkman but flashed a wrong file using fastboot. It was just a mistake and it was done after one second since the file size was only 90kb. There was no chance I could have stopped it. And now I have no access to flash mode, or fastboot. Battery is not chanrging anymore. It seems it is bricked :crying:
Is there any tool which can flash the hardware again? May be kinda developer tool... It makes me sad
Please help!!!

i have a similar problem. i have a wt19i manufactured 11w48 with .62 fw. i can't enter flashmode or fastboot. the led blink for like 0,5 seconds and then it boot into charging mode,showing the batttery on the display.i've tried testpoint, flashtool, s1tool(that says "finished", but can't flash anything since i can't enter flashmode nor fastboot) and every other method here, tried to restore/update with pc companion, but it's impossible without entering flashmode. how do i know if i have unlocked bootloader since s1tool seems to unlock but flashmode and fastboot aren't working? i have already rooted and bootloader status "yes". i have successfully unlocked/rooted/flashed in the past x10 mini(x2),xperia mini,xperia neo, xperia ray, xperia play,an lg p350, a galaxy ace..anybody willing to help? can't seem to find anything here on xda, everything i've tried doesn't work no flashmode or fastboot, just 0,5 seconds blinking led.anyone knows if is there a way or how to uninstall drivers so i can do a clean install? i've tried both the android sdk adb, s1 tool drivers and flashtools flashmode/ fastboot drivers..and last, couldit possibly be a hardware isue? phoneis working great and has no problem aside of what's said above..

[Q] C6833 Sony Z Ultra - Can not enter fastboot but flash mode?

Hi Dev's,
verified the bootloader can be unlocked via *#*#7378423#*#*
installed the fastboot, flashmode & sony xperia z ultra drivers from the flashtool 0.9.18.2 installer (flashtool.net)
on windows 8.1 with deactivated driver compatibility check.
Now i've tried all 3 methods to enter into fastboot mode from here
(theandroidsoul.com/sony-xperia-z-ultra-fastboot-mode)
via volume up + usb in, adb & quick boot reboot (even if the device is not rooted at the moment)
, but no success. The device always starts into flashmode, and this is the only state being recognized by the flashtool in windows. All hardware keys are working fine.
Any more ideas how to enter fastboot? I am really stucked at the moment.
Thank you!
what does it do on vol down and usb in?
You are doing this from a powered off state?
Hi,
I really tried every method and button combination. it is just the same as in this thread I found later.
http://forum.xda-developers.com/showthread.php?t=2716418
Seems like the fastboot mode is being hardware locked or something.
I return the device tomorrow, and check a new one (if I get) with android 4.2 stock Rom.

Totally Bricked: S1 Bootloader wrong. No flashmode/no fastboot/no boot only SOMC

Hello guys, today it's a really bad day for me. My M4 is now totally bricked.
Here's why:
I installed CM 12.1 and I will get back to stock, but my phone not enter in flashmode. So I flashed a zip file of stock rom but it not booted. I want to get Flashmode back, and I find a flashable zip that restore flashmode in Sony Xperia M. I flashed it and... bye bye M4. Now the phone only enter in SOMC FLASH DEVICE, Flashtool not flash, but say:
Device connected with USB debugging OFF. For 2011 devices line be sure that you aren't in MTP mode.
Sometimes enter in Unkown device. I have all drivers and I'm using original cable with USB 2.0 port. Now I'm trying to restore with PCC.
I removed the battery connectors for a while, put them back, but nothing changed.
My battery is at 100%.
What should I do?
So flash mode does not work anymore? This may seem inappropriate to say now that your phone is dead but if you have technical experience you could make a guide to opening and repairing the M4 or at least take pictures. But if flash mode or fastboot works try to restore it first
Well... Sorry to hear that :/ but uh..
http://forum.xda-developers.com/yureka/help/question-qualcomm-download-mode-k-t3068040
It uses a MSM8939 board same as ours. It's up to you if you want to attempt it but I'm suggesting not to.. Good luck anyway!
Thank you very much! Firstly I will try to send it to the shop where I buyd (sorry my english) and if they don't change the phone I will try this. Really thank you again!
EDIT: Ok, I am following the tutorial, but my M4 show only qhsusb_bulk with no driver. What I have to do?

probably you flashed custom kernel/rom with bootloader unlock=NO , you can try the S1 tool to restore your bootloader but you must have the original one.

I think wrong kernel makes this problem,
By the way, how s1 bootloader restore.
Any tools?
And how get original bootloader.
Is loader.sin is helpful from ftf?
Thank u.

you must have qhsusb_dload detected if yes then download this zip extract it and run s1tool, you must copy boot.sin and s1boot from your stock rom, the two files inside the zip are not for your C3, but you can try at your own risk.

Hi! I was a developer for the Sony Xperia M4 Aqua. For people that remember the time when still we wasn't able to root our device, probably you remember me.
I had a problem with my e2303:
I wasn't able to get in flash mode. Fastboot, recovery and normal boot worked.
One day, i decided to fix this problem. I re-flashed the bootloader s1 of the m4 aqua, but something happened.
My M4 Aqua right now is just a paperweight.
The phone does not boot in fastboot mode or in flash mode, no recovery mode, no boot and no leds.
Is recognized as SOMC FLASH DEVICE. But FlashTool won't start flashing. It says:
DEVICE CONNECTED WITH USB DEBUGGING OFF. FOR 2011 DEVICES LINE PLEASE MAKE SURE YOU ARE NOT IN MTP MODE.
PLEASE HELP ME! IF I WILL BE ABLE TO GET BACK MY M4 AQUA TO WORK, I HAVE MUCH PROJECTS FOR YOU, LIKE MIUI and others..
PLEASE HELP ME!!!

You will probly have to send it to warranty if you do not want to dissassemble it yourself since you can't really flash bootloader via usb? (I don't know how it is on our phone but on previous you had to dissassemble it to flash bootloader)
I already disassembled it
"I was a developer for the Sony Xperia M4 Aqua"
You don't understand irony do you?

M4 (E2303) stuck at Sony Logo - bootloader is not unlockable - Have NO recovery

Hi - have been searching these forums for days now but cant find a solution.
I am OK at flashing etc but am stuck now. Phone is stuck at Sony logo and won't go any further.
Phone is an Xperia M4 (E2303) and the bootloader is locked - have tried unlocking it but get 'Failed - command not allowed' so i'm guessing it is not unlockable!
I can't get into recovery (nothing happens when i try) and cant get into FlashMode either. I plug usb into phone while holding the volume down key. I CAN get into Fastboot mode which seems to work fine and is recognized ok by PC - drivers all installed ok.
Is there a way of flashing an FTF using Fastboot rather than Flashmode? or even installing any recovery. I have 32 and 64-bit Flashtool installed, i have FTF files and i have EMMA.
Can anyone help please? I would be very grateful - many thanks - ian
With bootloader locker you won't be able to flash anything. I had the same problem.
Desperately, my friend thought it was a good idea to put the phone on the refrigerator for a while.
Surprisingly, in the next day, I turned it on and the cold phone booted normaly and then I was able to set OEM unlock authorization on developer settings and unlocked the bootloader with sony unlock key.
Then I tried to flash a twrp, but I'm stuck back on boot loop again, and fridge didn't help this time.
Power OFF phone, then hold together for at least 30 sec in this order "volume down" + "volume up" + "power button". Then release 3 buttons and try to power on phone with power button. This procedure will revert your phone back to default settings.
I have the Same Issue Is your problem Solved?

Read this tread. It worked for me! Good luck!
Hi there,
Same problem as OP here.
I am trying to revive my wife ex-phone, model 2303 which has been forgotten for two years at least.
Stock rom
No root
Bootloader locked
Stuck at Sony Logo when starting up the phone.
Can boot in FastBoot (blue light) and is detected by PC
Can boot in FlashMode (green light) but PC doesn't detect anything. Nothing appears in Peripherals.
Any advices ?
What can be done in FastBoot mode with a locked bootloader ?

Also Xperia companion will install all needed drivers and could also recover device.
https://www.sony.co.uk/electronics/support/articles/00236877
Thank your for your advices.
But in Flashmode the phone does not even appear in computer peripherals manager.
In FastBoot, Sony Emma does not detect phone neither.

Have you tried using an older version of flashtool ?
Hi, sorry for the late reply.
Which version of flashtool would you recommend ?
Would it change anything as the phone is not detected in device manager anyway ?
