i flashed my phone using the hasa rom for GB and the rage kernel
now my phone wont enter fastboot or flashmode,
i've tried all methods: from flashtool (fastboot via ADB) and the reboot option in the phone itself
please note that the phone is in fine working conditon...but it just wont enter flash or fastboot mode
used the search option, found nothing
And you tried:
Turning off device, battery in, holding volume up (fastboot mode) and connecting while pressing volume up to pc (led should turn blue)?
Turning off device, battery in, holding volume down (flashmode) and connecting while pressing volume down to pc (led should turn green)?
Drivers are installed? Go to the flashtool installation folder -> drivers and install drivers again...
Hi
I am on a Neo, running Super Jelly Bean 7. Today I do something stupid then I want to change the kernel but I now UNABLE TO CONNECT THE PHONE IN FASTBOOT or FLASHMODE
I did try followings"
1) Phone off, press & hold Menu while connecting cable. Led flash blue once, then led off and Sony (text logo) appear
2) Phone off, press & hold Back while connecting cable. Led flash green once, then led off and Sony (text logo) appear
3) Phone off, then power on the phone. Few first seconds when booting, led is purple, then led off and the phone boot normally. When I connect it to my PC, flashtool recognizes it properly (says its a Neo phone). I tried to use flashtool to reboot the phone into fastboot via ABD. The phone reboot but not enter fastboot (screen shows like 1st case)
I also try to switch off phone for few mins, clear system/cache/data... restore the phone from my backup, or even make clean install new custom ROM (from zip file)... but all not work!
In my PC, I reinstall adb/fastboot/flashmode drivers... but seem nothing work
My system:
Xperia Neo - Unlock BL (via Sony site) - Rooted - Super Jelly Bean 7.0 - Shardul Seth PAC 4.1/CM4.1 Kernel from this thread http://forum.xda-developers.com/showthread.php?t=2043906
PC: Windows XP with full drivers for Xperia 2011 installed
Pls help me to identify the problem so that I can flash my phone a again
PS: I did flash ROMs (stock and custom, GB, ICS and JB) many times. And of course, I entered fastboot/flashmode many times.
This is hardware issue... same problem with me tried everything setool2, 4se nothing worked. .. Now your device can be flashed with testpoint if you manufacturing date is below 12w10... Only stock firmware

Hi Kana
Just to inform you that I have solved the issue but not really sure what is the root cause: Following is steps I make
- New (another) PC
- Another USB cable - Important to make sure good connection between PC and the phone
- Install updated driver from Sony site
- When connecting device to PC, DO NOT use automatic driver install. I manually chose the updated drivers
After that I now can reboot the phone into flashmode/fastboot again
Hope you will overcome your case
Hi there,
yesterday I tried to root my new Tablet Z (16GB, LTE, Model: SGP321, Firmware: 10.4.B.0.569) and it doesn't start since then.
I used an ubuntu live CD for all these tasks because fastboot doesn't work on my win 8.1 and my debian wheezy didn't have the libc-dev needed in its repositories (didn't want to mess with packets that weren't yet integrated into my OS).
What I did:
unlock the bootloader according to http://unlockbootloader.sonymobile.com/instructions
I followed the instructions here: http://forum.xda-developers.com/xperia-z/general/how-to-root-10-4-b-0-569-t2590781
a few annotations to this:
the firmware rar didn't include a "Recover.zip", so I used the boot.img directly inside the firmware rar
although sony and this CM tutorial use the "-i" parameter of fastboot, I didn't use it because it wasn't used by the tutorial
after I did the "fastboot reboot" step, the device wasn't listed anymore when typing "fastboot devices", which, I think, is okay since the device should restart then.
I think it didn't really restart, because the LED on the side glew red.
I tried to turn on the tablet but it didn't do anything (the LED kept glowing red).
I tried holding vol up and power for a few seconds (until the LED blinked first once and then three times) but the tablet wouldn't do anything except for the LED glowing red. at somepoint, the LED would turn off (I think that happened when I hold vol up and power for more than 10 sec).
I was able to let it glow red again by pressing vol up and power again and release the vol up button before the power button.
I also tried to use the PC companion on my windows machine to repair the tablet but the tablet wasn't even recognized (either using the fastboot-procedure by holding vol up while connecting the tablet nor normal plugging in...)
any ideas what I could do next?
Same Problem!
Hey wullxz!
I have the same problem. Red LED most of the time, and I cannot make ANY USB connection to the PC. The tablet won't show up in the device manager. So obviously cant use flashtool, nor PC companion. Ive tried all this volume up and down button stuff, but simply cannot get it to show up on the computer.. Tried a different USB cable as well.. Same issue. The USB port is definitely not broken. Its brand new..
Have you found any solution ? Or anyone else? Mine just got back from Sony Repair.. they wont fix it cuz they detected that Ive tampered with the original software.... meaning Warranty Lost!
Great!
hi,
i also sent mine to sony for a repair. i wrote that i did a firmware update and the tablet wouldn't boot afterwards.
i didn't try the bootloader-unlock again afterwards.
Help Needed!
Tablet Z with unlocked bootloader and rooted 10.1.C.0.370
My issues occured after a downgrade to 4.1.2.
I CAN:
1) Start my tablet, everything normal...
2) Charge my tablet
3) Go into safe mode
4) Go into fastboot mode (solid BLUE LED)
5) Use the memory card and use root apps (maybe this could help restore?)
I CAN NOT:
1) Get my PC to recognize that a USB device is connected. Neither in Mass Storage mode, Media mode, nor fastboot mode.
- Tried with several cables and computers (this is not a driver issue, since it won't show up at all in device manager)
- Flashtool obvious;y says, no device connected
2) Get in to flashmode: device blinks red for about half a second, then green for half a second, and then LED is off. Nothing recognized via USB on PC
3) Get into recovery mode
4) Update over WIFI (fails because unlocled bootloader I suppose)
Any help would be greatly appreciated!
i think you should open a new thread for your problem because it seems like it's not really similar to my issue.
you should get more/better replies in an own thread.

let it charge to 100%, check for flashmode drivers installed and then try attaching it to pc only when flashtool asks you to do it.

Hey thanks for your reply... It wont go into flashmode... Theres something fundamentally wrong.. I cant figure out what... I leave it plugged in for 48 hours..but it doesnt really get full.. the most Ill get the orange LED.. like 50%... now its on since about 12 hours.. no LED on at all... strange..
But yea.. no flashmode... Nothing showing up when connecting the USB cable... nothing in device manager..and therefore flashtool sees nothing!
SOLVED
Problem solved! I can't believe it. Two bad(?) USB cables. Bought a new one, charges fine, flashmode fine. Flashed stock ROM.
However the Camera still doesn't work. Maybe the problem of the cable inside which may have come loose!
xperia z2 not booting when only on battery and directly goes into fastboot when connected to pc via usb . also i can flash stock ftf files via xperia companion.
if i connect it to a chrger it shows sony logo and then charging screen. when i connect it to a pc without pressing any buttons it shows red led and then blue led ie fastboot mode . pc can detect it in fastboot mode. also i can flash ftf file so i thinkflash mode is also working. But when I remove cable and try to power it on nothing happpens. Also if its connect to charger or pc and i hold power button it vibrates 3 times and restart again. tried flashtools by androxyde also tried xperia companion. nothing works. plz help.
Mine did something similar to this, I got mine brand new in 2014. I ended up replacing the battery and thankfully it worked. I'm guessing that might solve your issues too, try putting in a brand new battery.
So basically I suddenly got this system ui error which caused my phone to go into a bootloop eventually when starting up you could only see sony logo and it would stay on.
I tried to use xperia companion to do a software recovery but my phone would not be recognized. (the led does turn green when you press volume button down)
I tried using flashtool and installed drivers without driver signature but again when flashing it doens't recognize my device.
When the phone is in fastboot mode the device is recognized by flashtool. I tried it with 3 different pcs and 3 different USB cables and nothing.
I have never done anything to my phone so the bootloader is still locked.
I was wonder if I can still recover my phone but than via fastboot mode.
phone specs:
Xperia z2 d6503
os: marshmallow
kernel: 23.5.A.1.291
Thanks in advance for any help
