Tablet boots to red triangle
I can get past this by holding volume up + power, but have to do it every time.
Not rooted
did the factory reset
Have adb and fastboot, adb sees the serial number
Bought a fastboot cable, but does the exact same thing, from Atomic Market

I got a tablet device (Omega OT107) I've rooted it using
Code:
ro.kernel.qemu
method.
Next I'm triying to flash Custom Recovery and my problems started here.
What I've tried:
1.
Code:
flash_image recovery
- no success process of flashing never ends
2. Install bootmenu to /data/bootmenu
3. Installed 2 different 2Init's
None of this worked or even had an impact on how device works (it always boots in android correctly).
I've tried to boot it to fastboot mode to flash recovery from there but there is a problem that I have.
Volume(up or down) + Power buttons starts device to Android not to bootloader (I've read you need to remove and reinsert battery to make it work, but device has a build in batery and needs to be taken apart to remove it so I did not tryed it)
Code:
adb reboot bootloader
- boots to what I think is a bootloader (screen is black(no light is comming out of it)) when connected to Windows PC it is seen as Android Bootloader Interface (Android-SDK driver).
Code:
fastboot devices
does not discover any devices, clicking volume or power button does nothing.
Code:
adb reboot recovery
- boots devices it what seems to be useless recovery mode. At start there is a standing android dude with fireball on his chest, and imidietly changes to a lying position with his chest oppened and an exclamation mark comming out of it (I've red it is ok and I need to press Volume(down/up) + Power buttons to open recovery menu but it does not happen).
My question is:
Is it normal to some devices bootloader to look like mine? How to make it discoverable to fastboot?
I had this issue and I fixed with "press all the buttons!" and suddenly I sow recovery menu...to factory reset. if it doesn't work repeat with rebooting with pin
Does someone knows a way how to hard reset this thing?? ^^
about firmware
Any idea where find the firmware for this tablet?
Mine is now freeze on recovery logo
hard reset OT107
1.Turn off our tablet.

3.Wait until the Android image.
4.Then VOL + button and the POWER and appears to us to Recovery Mode
5.Navigation is Vol-i + and confirmed by pressing POWER.
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)
Basically after using adb reboot bootloader my tablet rebooted and got stuck on the logo. I have tried to
access the recovery mode by turning it on, while holding the up and down volume buttons, but nothing happens.
Moreoever, whenever I connect it to my computer, windows recognise it as USB Developer.
Any ideas on what to do?
Ok, it seems that if you leave it to fully discharge its battery, the bootloader command gets reset and its loads just fine.
Gonna mark this as solved
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.
I tried to enter recovery to unlock the bootloader but all i get is a blank screen with the LED shining blue.
I tried it through adb ( adb reboot bootloader) and the button combination (vol. up + plug in cable).
Also tried adb reboot recovery, but it only reboots back into the system and vol. down + plugging in cable results in the same blank screen but with a green LED.
Please help!
No recent Sony device ships with a recovery.
In order to unlock your device follow the instructions in https://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Next time before opening a new thread read the forum. Chances are your questions are already asked by others. Good luck unlocking, flashing and freeing your phone.
