Hello,
i have a bad problem. My 5T freezed during usage and when i boot it does not boot, it reboots immediately showing "Press any key to shutdown" on top left.
The same thing happens by booting volume down+power or volume up+power.
I cannot boot it in fastboot, adb devices and fastboot devices commands do not recognize it.
I've read on the net that for this problem i could have connect the phone to an old usb 2.0 port, but it does not work.
Can anyone please help me?

Background: I flashed my tablet with a wrong ROM.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
This what happens to my tablet when I boot it up:
Without USB and DC connected:
Booting normally: Tap power, logo appears and disappears, 1-2 seconds later the tablet shuts off
Booting to recovery mode: hold power + vol down, logo appears, logo disappears and shuts off.
With USB connected:
Booting normally: Same as above
Booting to recovery mode: hold power+VolUp, logo appears and disappears, Android system recovery utility v1.3.38 is up.
Note* I can use volume controllers to scroll the list however I cannot click on any of them. Tapping power doesn't work nor any other button on the tablet.
With USB and DC connected:
Booting normally: It boots into the ROM, but I cannot click anything. There's no response from touch nor any other button (only power that will turn on screen after it dims)
Booting to recovery mode: Same as above
Booting into download/flash mode: I hold Reset+VolUp+Power and it will show black screen. In the PC, it says 'unrecognized or malfunctioned USB'.

I have Windows 7 64bit with Android SDK installed. I have the official USB drivers and FlashMode drivers, neither of them gets accepted when I try to install the driver.
I also got Ubuntu and here are the logs I was able to come up with:
Booted into the ****ty ROM and then I plug in USB: http://pastebin.com/vnc2q5nU
I plug in USB+DC and boot into flash mode: http://pastebin.com/qa2URP9c
Hi,
I'm new here.
I have an issue. My Android phone is bricked. It is an MT6515 phone; model i9270+ (Chinese dual SIM phone).
I had trouble rooting it, so I was half way there following steps in THIS thread.
To see more specs. about this phone check HERE (chrome tells me that this site has malware, but I ignored it...)
On to the issue...
I accidentally flashed my phone with the wrong boot image from fast boot ("fastboot flash boot boot.img"). I had a clockwork mod backup copy of my own boot.img, so I just wanted to reflash it. Fastboot said that the flash failed.
I tried again, and then in the middle of the process my command prompt stalled. Phone was in flashing process for about an hour, so I hit Ctrl+C to stop it... I wanted to do a recovery from the phone itself using clockwork recovery...
When I wanted to boot my phone there was no screen light. The phone just vibrates twice and that's all.
PC won't recognize it, so I can't go back to fastboot mode. Key combination (vol up + power) won't bring fastboot mode...
This phone seems completely bricked...
Is there anything I can do to "revive" it?
I googled my issue, but I couldn't find anything useful. All simple solutions like getting the battery out for an hour, holding some weird key combinations, plugging it in USB on a different port, and such didn't get me any results...
Can anyone help me, please?
Thanks in advance!
More info...
Ok, I've just tested few more things:
When just holding a power button - phone vibrates once, and second time about 4 seconds after
When the battery is out and the phone is on USB - it does nothing
When the battery is in and I plug the USB (without pressing power) - it vibrates once, and second time about 1 second after
When holding Vol Up + Power (on this phone this is entering to fastboot) - does nothing
When holding Vol Up and plugging USB - PC recognized it as "SCI USB2Serial (COM10)" device, and the driver installation failed.
Before I typed this whole post PC recognized my phone as "unknown device", and the driver installation also failed.
Commant "adb devices" or "fastboot devices" does not recognize the phone while being plugged on USB.
When I plug it on electrical charger it vibrates twice just like pressing the power button.
Programs like "MTK Droid Root & Tools" do not recognize it...
Can anyone help me?
How to input in a new software? I have Boot.img, System.img and Recovery.img ...
@Admin -> you can close/delete this thread
I sold my phone... Some dude needed speakers, display and touch digitizer, so I this phone was of some good use for him
I accidently wipe system and stuck on boot! :crying:
How do I access to recovery? I want to restore the system. Is there anyone knows how to boot into recovery by using something else?
Hold down power for 10 + seconds until phone is fully off, then try the hardware button press again
( volume down button whilst powering on.)
Usually the hardware buttons will override and stop it trying to boot
If not will adb recognise it if you plug it into PC?
plug it in and in cmd type 'adb devices'
if recognises try 'adb reboot recovery' in the cmd prompt
Hello XDA Community,
Sorry I didn't know where to post this...
Two weeks ago I purchased a Lenovo S8-50LC Tablet. It was working fine until last night, I was watching movies on Youtube and chatting with some friends. Then I went to bed and there was still around 50% charge in the battery.
When I woke up, I tired to wake up the device but it didn't respond. I thought it was stuck or something, so I tired to hold the power button for 20 seconds to do a hard reset but still didn't work. After that I plugged it in to a power source with the compatible charger that came with it and the screen light up with no data on it. I tried to power it on then and it showed the Lenovo logo and in a very tiny font underneath the logo it said "Boot Fail, Efi hard drive".
Then it would take me to a screen which says:
"EFI Shell version 2.31 [1.0]
Current running mode 1.1.2
map: Cannot find required map name.
Press ESC in 5 seconds to skip startup.nsh, any other key to continue.
Shell>_"

and that's it!
I don't understand why this screen appears. I mean the tablet was working properly over the night and it had no issues whatsoever, but now it doesn't boot!
Then I tried to power it off and press Volume UP + Volume DOWN + Power Button, it showed a black screen with only one line: "FastBoot Starting...Can't get eMMC Info, revert to default value!"
http://imageshack.com/a/img661/1158/bRg9jj.jpg
That's all what I got...
PS:
1- The tablet does all that only when it's plugged to a power source, but when it's not plugged, it doesn't show anything.
2- When I plug it into the pc via USB, the pc doesn't recognize it.
3- I tried to boot into fastboot mode or recovery mode but it doesn't work either.
Please help me fix my tablet and I hope it's going to be soon. Thank you all in advance!
UPDATE:
1- I left it on the charger for maybe 2 hours and now it's turning on without being plugged in to a power source.
2- When I press Volume UP + Volume DOWN + Power Button, it shows the previous mentioned phrase, but now when I connect it to the pc via USB, windows recognizes it as Lenovo Composite ADB Interface under Android Phone

3- Tried to perform some fastboot commands like flash, format and erase, it always fails with the error:
Failed (remote: unknown command)
UPDATE2:
1- When executing ADB commands like adb devices it says "no devices found"
anyone?
Hello. A friend of mine has the same problem. He dropped the device and the screen cracked. After a reboot the tablet is on the same situation. I plugged a keyboard via otg , it stops the countdown in the EFI SHELL, but i can not type anything. I think is an eMMC related problem.
I guess the eMMC is totally fried or something. But, I mean, I didn't leave it on the charger all night or anything, why would it do such a thing!
any solutions or suggestions??

Thank you for your reply but it doesn't work .. as I mentioned earlier I don't have a "download mode" because any key combination I try to use just sends me to the shell window .. anymore suggestions would be appreciated!
-unplug usb cable
-turn off
-hold (volum+) and (volume -) towice
-press power button
It should go to fastboot quickly (a black screen with a little text)
Hi guys!
Is there any way to put Bay Trail based device into recovery/fastboot using USB keyboard?
My device (Chuwi V99i) has just 2 physical buttons: power and vol- (pinhole under the camera).
Current observations:
If I'll start device while vol- is pressed, then it was entering non-functioning fastboot mode i.e. device was seen by fastboot utility but any command failing instantly.
If I'll start device while vol+ on usb keyboard is pressed, then it was booting safe mode.
If I'll issue "adb reboot bootloader" then device was entering fully functioning droidboot.
If I'll issue "adb reboot recovery" then device was entering non-functioning recovery ("No Command" screen without any reaction to vol- or power button).
I was also able to reboot from droidboot/recovery using ctrl+alt+del on usb-keyboard.
If you can help me, I would really appreciate that!
P.S. I'm advised to post on this forum by XDA Assist.
