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!"

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,
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?

I sold my phone... Some dude needed speakers, display and touch digitizer, so I this phone was of some good use for him
Hey Guys, so i never usually post because i can usually solve my own problems, but i think this time i've out done myself.
So last night when installing CM12.1 using TWRP my xperia Z2 everything was looking rosy. Then when I tried to turn the phone on to boot the first time it gave me just a single little vibe but would not turn on.
I've tried ALL combinations of button resets - Nothing
I've tried to re-flash a stock image using flashboot - Nothing - it won't recognise flash or download mode when i plug it into my computer while holding down volume down
I've tried holding the volume up button while plugging it into my computer to try FASTBOOT mode - Nothing - the blue LED on the top comes on, but neither OSX or WIN7 recognises anything has been plugged into the computer and it doesn't register on ./fastboot devices
So have I actually properly ****ed my device? Or am i missing something?
Any help would be so massively appreciated. Like i said, i usually never ask.
Did you try another cable? Blue LED is good, so fastboot mode should work.
When it would be bricked, there would be no blue LED...
Did you look into device manager on WIN7? Any device like "S1boot" or "Sony ADB Interface" there?
Sony logo showing up, when turning the phone on?
Try "fastboot reboot or "fastboot reboot bootloader" even though "fastboot devices" doesn't show up as anything (weird). It should boot back to bootloader and register your device. This happened to me once.
I think it's "fastboot reboot-bootloader" and i think it won't work...
Try
Try holding the power button and volume up button in until it vibrates. Then you should be able to hold power button and volume button to get to download mode. This works on mine when all else fails, lol.
Hi all,
I have just recently rooted my 306SH, the rooting process was fine. The problem started when I flashed an incompatible twrp image. Now I can't boot into anything it seems, no recovery, no fastboot and the power button will show only the logo screen. If connected to a power source the red led light will stay on even if unplugged. The device can be completely shut down and the red light off if I hold the down+volume and power down for few seconds.
I can connect it to my computer via usb by holding up+volume and power (green led light) . I installed google usb driver onto the android device and it stays connected for about 30 seconds to 1 minute. I tried using command prompt and SDK by typing "adb reboot recovery" but get an error message "error: device '(null)' not found.
Things I have installed on my computer:
(ADB, fast boot and drivers) https://forum.xda-developers.com/showthread.php?p=48915118#post48915118
SDK Platform-tools
306SH:
Google USB driver
Is there anything I can do from my computer? I was thinking maybe I can flash in an image to replace it. And also my sim card pops out and can't be set back in, is this due to the incorrect flashing?
Any help or input is greatly appreciated, I've been working on this for a while and is getting no where.
Hello guys ,please forgive my ignorance, a few days ago ı downloaded an application to my asus k011 and honestly the internal memory was almost full (someting 3,80gb) it got so slow and turned off by itself, now freezes on ASUS Logo never starts, no access to recovery mode, (Pressing home+volume up doesn't get me there either) when ı connect it to a pc, pc recognizes it as android device but not as K011 , ı have tried adb commands(recognizes the device as abcdefg1234567890 on command prompt) it did not work also, ı have heard that it is possible to recover it's recovery mode via xfstk downloader but ı couldn't find it's firmware image file. Sorry for writing too much
Had similar problem look on my post asus fonpad 7 hard bricked .
But first try this:
make sure your device is off if not press long power button. Now press together Vol + and Power button at the same time , it will vibrate but don't release keys , once ASUS logo appear release both keys and fast press just Vol - button several times until you see USB logo and Droid Boot screen and plug back usb cable .
I tried to enter download mode through recovery mode since I couldn't find the proper key combination for the M31 online. But now it's stuck in a black screen with nothing but the words 'entering fastboot' on top. I can't restart it.
I've enabled developer options and OEM unlock but that's all I did.
Press the power button for a long time (A minute at most)
Thank you!

yo it isnt working pls help me out
Just documenting my (M315FXXU2ATJ9) solution (found through trial and error) in case this happens to somebody.
This is what worked for me:
1. Connect your phone to your PC via USB
2. Hold down VOL_UP + VOL_DN + POWER for 10 seconds
Your M31 will turn off and the charging logo will appear.
You can now simply disconnect the USB cable and turn it on normally.
Hope this helps.
Hello,
I had updated my M315F to official OneUI4.1, but I am having battery issues and the phone is bit laggy, so I decided to revert to OneUI3.1 using Odin tool, however on entering the recovery mode and getting into "Reboot to bootloader", device stucks at "Entering fastboot....", and its unresponsive as download mode doesn't start. The first time I did without unlocking the OEM, but even after unlocking the OEM and entering the bootloader, it says "Entering fastboot...., so again restarting phone and repeating the same process. Download mode doesn't start.
Is there anyway to reboot to download mode?
Thanks in advance
Help is much appreciated
Regards
