Hi guys, I am using sony xperia U (st251, Android 2.3.7, kernel version 2.6.35.7 [email protected]#1). my phone is not detectible by any computer (used different laptop and PCs) . I tried with win 7, win 8 and win 8.1 with different cables. Phone is not staying in fastboot and flashmode green light appears for a second or two and it goes for charging. I used flashtool installed and phone driver (which is available in the driver folder of the flashtool) fastboot, and flash mode drivers are installed properly..but no luck yet. I tried removing the battery and connect the phone and then insert the battery. i used volume down and power button for flash mode and volume up and power button for recovery nothing is working, even hard reset is not possible with keys.
When phone completely drained out of battery, charging is only possible with usb cable not through AV....plz help me

Recently, I bought a xiaomi redmi note 3 with the 650 version. I switch to Miui 8 China Fastboot Room from a Global Fastboot Rom, also for unlocking the bootloader. But after I have finished my flashing, it turns out that the Note 3 can't turn on, Stucking on the MI logo for 2 times then turns off again. I tried connecting it to the PC, but the led blinks red. I tried to flash the Miui again but it doesn't show the device. My PC recognized the port as Qualcomm HS-USB Diagnostics 900E, but I can't take it to EDL mode. I tried entering it from the Fastboot mode but still didn't work. Any Help?
*P.S: It also blinks red when I entered the Fastboot Mode
Just checking, but did you use the fastboot edl v2 to enter EDL?

when i fail to unlock bootloader in official method then i tried miui8 flashboot Rom from mi flash tool with modified emmc_appsboot.mbn file from one of the developer i bricked my Redmi note 3 Qlcmm650
solution:- 1) remove back cover & disconnect the battery around 1 minute reconnect it (recomended one if this not possible for you then try 2nd method)
Or
2)full discharge the battery Then charge it more then 35% (it will also work as diconnecting the battery)
connect the computer &and press volume + & - button together
connect the PC & vol buttons press both are at the same time then you enter the correct EDL mode (same red light but this time correct EDL mode you can flash the rom use official Fastboot rom Dont modify the contents)
if i helped you hit thanks
I was in same situation today: Mobile doesnt do anything else then red-blinking, no edl or fastboot. Pc only saw "Qualcomm HS-USB Diagnostics 900E".
Found the solutions mentioned by Chinmayhegde, but i didnt get the cover off the device and dont want to damage new mobile.
then i found the method "Deep Flash".
its small manipulation of usb-cable: put a small wire on second terminal, put in pc and then pull the wire.
i succeded after second try. then pc sees "Qualcomm HS-USB QDLoader 9008" again and miflash is able to flash the device.
see this tutorial for creating the modded usb cable: http://en.miui.com/thread-310325-1-1.html
Hope it works
if your phone still able to enter fastboot, you can try to use fastboot to edl v2 to enter download mode
if it still not help, most safe & easy mode is using deep flash cable as above post
I have same problem.
Even I try booting fastboot mod but it keeps restarting.
Even fastboot logo comes by just pressing volume down button. So I think power button is stuck. That's make phone restart all the time.
How to overcome this problem?
Thanks

Try To Remove Your Battery than Use MiFlash Tool To Flash Your Mobile Bro.
Hello guys,
Recently i was browsing facebook when my Sony Xperia T3 turned off suddenly.
It wont turn on anymore. I have already tried the little button beside the sim slot and VOL+ and Power button.
When i disconnect the battery it is the same problem. I have connected it to the Computer and it says qhsusb_bulk. I have installed the driver for it now it says SEMC Flash Device or SOMC Flash Device. Flashtool and PC Companion cant recognize the Phone too.
I have also tried the Testpoint but it did nothing.
So I hope for your help.
Thanks before
PS: Sim and SD Card are outside too and the phone does not seem to be charging or anything

dear all...
i have a very strange situation here, after my kenzo updating to MIUI 9, when i enter fastboot mode and plug in to my USB, it was not detected anymore on device manager, and when i turn off the phone, and i plug in charger, LED will blinking red on the top of the phone,.
if the phone is turn on, charging is working, USB is detected by computer...
is this somekind of new protection from Xiaomi? or i have problem in my hardware? i was planning to downgrade again to MIUI 8 using EDL mode but when i plug the EDL special cable it was just blinking RED.
any opinion or anyone having kenzo device can try to detect fastboot and charging on power off condition? and share feedback?
thanks a bunch
I had the same problem and i opened the back case and unplugged the battery pin and plugged again.
i did it already re plug the battery now phone only hang on logo, can access fastboot but not detected in my computer, try using Deep Flash cable, only blinking red, try charging only blinking red
bump, anyone?....
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
