Today I was going to reboot my htc one m8. But something bad happened.Help! stuck with formatting/cache... when trying to reboot. And I have been stuck with this for like an hour...
Then it restarts and the text disappear. Only a picture of small phone with green circle is on my phone. I can press volume+ and power to turn it off or volume- and power to restart it, but the small phone comes back every time. I don't know what to do...
please help me out....T_T
Is the phone stock, or any mods (bootloader unlock, root, etc.)?
Green circle is stock recovery. You can press vol up+vol down and power to get recovery menu options, but not sure anything there will help you.
You can likely RUU to get back up and running. But personal data will be wiped.
Hi there
I have recently been given a broken Sony Xperia Tablet Z. When the power button is pressed a red light flashes 3 times but nothing happens. When the vol+ and power is pressed nothing happens. When the vol- and power is pressed the red light flashes three times again.
Is there anything I can do to fix it?
Many thanks!

Hi there!
I've had on charge for a while now and still nothing. Would I need to be able to get into Download mode to flash with flash tool?
Thanks!
After charging the tablet for several hours, do this.
Press vol up + power button and hold until white led blinks 3 times.
(This will make sure the tablet is properly powered off. If after a long period no 3 blinks of white led, then it might mean that tablet state is already off. Press and hold just the power button and see if white led will blink just once then let go power button. The Sony logo should follow. All this is to see if tablet can shut down or power up properly or not. If it cannot do even the basic, then I have no idea how to proceed. This is why I don't trust my important data's in the internal emulated sdcard. I prefer my data to be in removable microsd. If tablet becomes dead and cannot be switched on, then any data that is stored in the unremovable internal emulated sdcard will be trapped. )
If you are lucky, the white led blinks 3 times it means that the tablet can be properly shut down, then ..
Then, connect a usb wire to the tablet. Do not plug the cable to the pc yet. without pressing power button, plug the cable to the PC WHILE you press and hold vol up button.
If you get a blue led at the side of the tablet, it means your tablet can be put into fastboot mode.
Do this first. I believe that once the tablet can be put into fastboot mode, then the tablet can be restored by flashing a recovery boot loader.
If you cannot get the tablet into fastboot mode, then I do not have enough knowledge about how to proceed. You will need to bring it to a service center for repairs.

Hi there!
Thank you both for your help! I can successfully get the device into fastboot mode.
When trying to enter flashmode the device flashes green then goes back to red.
Is there anyway of fixing the device?
Many thanks!
First thing you need is a recovery boot loader.
This link helped me but I use Ubuntu linux to install recovery boot loader into my Tablet z wifi. (I think it is also possible to do it in windows but you will need to install proper drivers)
Before this step, I also used Flashtool under windows 7 to unlock my bootloader. It is not difficult to use Flashtool and unlock bootloader but you must decide how important it is to you to backup TA before unlocking bootloader. In my case, I didn't feel I need SONY bravia engine, so I didn't backup my TA.
1. Use Flashtool to UNLOCK
2. Use Fastboot to install TWRP recovery loader
3. Download a Custom Rom (CM11/CM12/Omnirom./PAC) and save it to microsd
4. Boot into TWRP Recovery, clean data / cache partitions and flash custom rom from microsd
http://forum.cyanogenmod.org/topic/93490-soft-bricked-my-xperia-installing-cm/
To fix the problem, I downloaded CMB from http://forum.xda-dev...d.php?t=2463423. I unzip'd it, and used fastboot to install the boot.img: "sudo ./fastboot -i 0xfce flash boot pollux-windy/cmb/boot.img". Then I rebooted into TWRP recovery, and wiped/reformatted everything (including /data, which CWM wouldn't mount or wipe). I then sideloaded the CM11 ROM, booted back into TWRP, and installed CM11 from within TWRP. I ended up reflashing the CMB boot.img back on, even after installing CM11, and everything seems to be running great now.
Hi, same problem. Good answer was here : https://fr.ifixit.com/Réponses/Afficher/273255/black+screen+and+red+led+blinking+3+times#
In fact, my Aukey Quick charger did the thing: https://www.amazon.fr/AUKEY-Charge-Chargeur-Secteur-Samsung/dp/B01AHY1XAY
Hi
My Z Ultra stays on android logo. Reset button don't work and power too. I tried reboot from adb (because its connecting normaly) and now stuck on black screen with red led. It's not charging, i left for like 2 hours and its only reboots to baterry symbol and reboot again. Can't get into flashmode and fastboot, red led appears and nothing else. What can i do?
Did u try power button + vol up for 10 sec? Then when he vibrate put charger in and go to bootloader for fastboot kernel or whatever you want
I just tried and it's don't vibrate
I think if I remember correctly red LED and no response is a motherboard/flex cable issue (could be wrong) this happened to me when I flashed the wrong software, I was still under return policy.
But yeah if flashtool isn't picking it up, you're SOL.
Hello there,
first sorry for my bad English, if you cannot understand me please ask
My friend asked me to (factory) reset his M4 Aqua because it won't start anymore (boot loop).
I used the flashtool and flashed the 26.3.A.1.33 (Customized DE for E2303) with standard settings (without flashing the userdata)
It worked without problems and the phone started until it said, "Android is starting...". Some seconds later the phone rebooted and stuck at the Sony logo with a glowing red LED.
After a half an hour I put it off by pressing the power and volume up button until it vibrated three times.
I tried to put it back into flash mode but nothing happened (LED doesn't blink, PC don't recognises the phone - just nothing). Same for the bootloader.
I've read something about holding the volume buttons and the power buttons for 30 seconds to reset the phone, but it doesn't help. (Flash mode and bootloader still haven't worked)
I pressed the off button near to the sd slot for ~15 seconds and after that, I was able to put the phone into the flash mode, but the PC still doesn't recognize the phone.
After removing the USB-cable the phone doesn't exit from the flash mode, so I press the off button again until the green LED went off.
I've noticed that the bootloader works, but the bootloader is locked and I was not able to unlock it.
So by now:
The phone stuck at the Sony logo with a bright shining red LED,
flash mode doesn't work (green LED lights up, but the PC doesn't recognize it),
the bootloader is locked (but works).
Please tell me, if you know how to revive the phone.
thank you in advance
You will have to flash the firmware again with flashtool maybe try and download another ftf file from a different source and try again.
Remember to only connect your phone in fastboot mode when flashtool prompt's you and all should be good.
Please help me
