[Q] Flash Mode Reboots while connected

Hi, so I have a stock ICS rom on my lt30a, and im trying to put the Jelly Bean update. This is the first time im using flashtool but I did my research and knew everything I needed to do. One thing keeps preventing me from flashing it to my phone. I put the phone successfully in flash mode, green light, its recognized in flashtool, excellent, then after a short period of time my phone just reboots, shows the sony logo and is charging normally. I think my computer just keeps not recognizing the phone again and again but as far as I know all the drivers are installed.
Any ideas?
Cheers

Ok then looks like usb debugging is turned off goto developer options and turn it on and try flashtool again also make sure to allow mock locations in that same menu
hope this helps

Huh it says in developer options that usb debugging is on. I turned on mock locations and will try again. It could be the problem is with my computer or Windows 8 not flash tool or my phone

Before connecting the phone, you must prepare the ftf file. Drag and drop it into the open window of flashtool and only connect the phone when promoted to

I'm nervous about doing that because one time I did it and I just assumed there was a time out, so I quickly went into flash mode and started to flash the ftf file. It said preparing then a second into actually flashing it disconnected. I thought I had bricked my phone but it booted fine.

Well, thats the way to do it. You must let flashtool prepare the files and only attach the phone when it prompts you to do so.
Tell me what happens when you do it. I cant help you if I dont know if it disconnects whilst actually flashing. Please copy and paste the log from flashtool

Actually one thing I just noticed that my phone is doing which as far as I know has never happened before yesterday is when I hit turn off the phone turns off then reboots normally when it should just stay off. Might this be some contributing culprite. I cant try to flash it right now but i will when i can. Thanks for the help
Edit: Also just noticed that windows drivers is having trouble downloading S1 boot drivers. I dont know if this is relevant

No need to say thanks, just hit someones thanks button if you want to say thanks.
That is a seperate issue from 303 or 195 FW, I beleive it is gone on 223 and 498 FW
But what you can try is to press volume up and power button to hard reset the phone. Do it untill it vibrates once AND THEN KEEP PRESSING UNTILL IT VIBRATES 3 MORE TIMES. Then try connecting in flashmode

I should have asked this but is there actually a time out for the flash mode?

Power and volume up together until you get three vibrations. There is no time out for flash mode

Could the problem be driver related? When im in flash mode my computer starts to look for S1 boot but doesnt have enough time for it to download the necessary driver. If so can i get this driver from somewhere else?

Is it detected with Flashtool?

@lexykon : i think since ur device responds, its not a total hardbrick. Flashing an FTF using flashtool should help

no it says no device connected

You have to push Hard reset button (red button just near the SIM card) until phone vibrates 3 times. Then you push volume down button and then connect PC microUSB cable into the correct connector on your Z1.
Flashtool should see your phone. Then you can flash with flashtool back to your previous (stock ?) ROM.

Strange. Did you connect the usb cable to your phone AND maintain volume down button?
Because USB debugging OFF is only when your phone has started Android. When in Flashmode Android is not started.
So after pushing red hard power off button and phone vibrates 3times (it's important it vibrates 3 times) :
- close and restart Flashtool on your computer,
- choose Flash button (strike icon), choose the FTF of the stock firmware then validate and then check 'Flashmode' then OK, it will work few seconds and bring you a new screen explaining you how to get into flash mode with a phone and cable in a Window,
- take your USB cable in left hand,
- push down volume button with your right hand
- connect your cable in micro USB port AND maintain volume down for a few seconds
I decomposed the steps because it is important not to wait too long when connecting cable onto your device and launching Flashtool (that's why I prefer to launch it before, as described above), because if the phone detects current in its usb port, it starts system. It is important to be ready and having Flashtool launched BEFORE plugging the cable.

That's quite wierd. The fact that phone's LED becomes red is a good sign, i.e. going to flashmode.
IS it Flashtool saying the phone is in USB debugging ? If not, you can then flash after the LED ran red with flashtool.
Flashtool may say it's USB debugging OFF if Android is booted.
If in flashmode, Flashtool should say :
03/043/2015 15:43:18 - INFO - Device connected in flash mode
And then you can flash...

Have you tried fastboot? Volume up while plugging cable.
Perhaps you can flash a boot.img from there and use recovery at least.
This is what happens to my phone when the kernel fails to flash, usually after restoring a nandroid.

Ok you shouldn't have that in your flashtool log.
Without the phone connected to the PC, you should have the following message, especially "Please connect your device into flashmode" :

03/050/2015 16:50:49 - INFO - Please connect your device into flashmode.
From my point of view, it doesn't seem your phone is powered off.
Then to Power Off hard press the red button near sim card, just above the chrome power button until phone vibrates 3 times :

Ok dude. Sorry but I can't help you anymore. Maybe advanced developpers could. My knowledge on flashing Z1 is 2 days old only
FYI, my LED is blinking 1 time red and 1 time green very quickly when I power on my Z1 in flashmode. Nothing on screen, but Flashtool detects my device in Flashmode.
Maybe, as proposed by markuz85, you should try Fastboot mode (volume up instead of volume down)... but I never tried this and I won't be helpful on that.
Good luck and tell us if you have got something.

Z3 Compact stuck on bootloop no recovery

Hi guys,
So I'll tell you the whole story here. I was on Lollipop, fully rooted with working XZDR recovery but phone seemed laggy so I decided to give it a full format with the newer firmware. So I backed up everything. Booted into recovery. Formatted the whole phone, then took out the SD card to load on the zip file from the PC. On inserting it, it wouldn't be detected so I tried to reboot into recovery using the inbuilt option but forgot that recovery too would have been deleted. Since then its just stuck on the Sony logo. It reboots by keeping the Power button and Volume Up pressed, but to no avail. I tried to flash the image using Flashtool but it doesn't recognize the phone when I try to connect it in Fastboot using the Volume Down during Reboot method. Nor do I get a blue LED on the phone. I guess it isn't entering Fast boot.
Please help out since its my daily driver. Help appreciated. Thanks

Oh hey guys managed to restore using Flashtool. Tried booting phone into Flash Mode again and idk how it worked this time. Breathing a sigh of relief.

Could you please explain in detail how did you managed to get out of bootllop....it seems i sucked exactly like you & now clueless....

First of all, try repair it with Pc Companion. If that doesn't work, try with flashtool.
Keep in mind, to enter flash mode, press volume down button and insert usb cable.

tried PC companion & got error 2003 (Unlocked Bootloader & rooted wont work it seems)
Flashtool, will give a try again....
As of now, i am able to go to the fastboot & can open files on my PC when connect phone via USB cable....
Phone not booting up normal/recovery mode....It just stucked with boot loops

Tried flashtool---Ended up with errors as attached pic
As i cant bootup my phone...USB Debugging option cant be ticked
I was running SlimLP (unofficial) while bricked my phone....
Anything on that please....

Not sure what you mean....... all I can say is, Flashtool 0.9.10.2beta4 does not require USB Debugging to be turned on to work and I definitely didnt turn USB Debugging on before starting the root process. Later yes but not before.
Try it or not, thats up to you.....

Try this: press and hold power and volume up button for 10 seconds and see does the phone vibrate.If vibrate flash again via flashtool.,he should works.

Battery was fully charged and I've tried that but phone does not response at all to flashtool. When plug in to PC, in device manager under USB controllers, it sees it as SOMC Flash Drive. I think the phone boot is dead.

Thanks for your help...The phone was flashed successfully with flash tool with flash file E6553_28.0.A.4.8. After flash done, phone was dead, cannot power on anymore. Now when I tried to flash it again, volume down, insert USB the flashtool show as: Device detected with USB debugging off. It doesn't go to flash mode anymore. I took the back cover off, remove battery connector flex cable and connect it back and try flashing many times but flashtool will not detect phone in flash mode..PC can detect phone because it makes connecting sound on PC but detects as what mode I don't know. In device manager, it doesn't show any device in com port but it shows SOMC Flash Device in USB controllers. I tried to press volume up + power but nothing happened. Once again thanks for your help.

somc flash device means dead boot....its no solution yet for it,sorry

Now when I tried to flash it again, volume down, insert USB the flashtool show as: Device detected with USB debugging off. It doesn't go to flash mode anymore. I took the back cover off, remove battery connector flex cable and connect it back and try flashing many times but flashtool will not detect phone in flash mode..PC can detect phone because it makes connecting sound on PC but detects as what mode I don't know. In device manager, it doesn't show any device in com port but it shows SOMC Flash Device in USB controllers. I tried to press volume up + power but nothing happened. Once again thanks for your help.

As I understood, you tried to downgrade. Am I right? I heard that sometimes downgrading causes hard brick. I don't know how to fix it but only option is bringing service.
