[Thinkpad Tablet General] XShunyaX:
Hello,

before I get into detail with my current problem at hand, I want to say that I'm extremely new to flashing/rooting my tablet and in most cases am very dependent on guides and how-tos. That being said, I've search through this forum among others in order to get my problem solved but had no success so far. So your expertise is basically my last resort and hope.

I have a Lenovo Yoga 2 1050L, as stated above, and tried to root it yesterday using this guide. Unfortunately, I messed up when it came to the system's image from the custom ROM because I downloaded the original firmware for the 10'' version L instead of the further below mentioned recovery firmware in step 3 (though that link was dead anyway). Moreover, I also included the recovery.img in the custom flash process and not only the system.img and I think the error occurred while flashing the recovery partition.

Long story short, the flashing process failed and I was left with a non-booting tablet.

The status-quo is I can boot into the bootloader mode (power button + volume down) where it'll say "normal boot", "recovery mode" etc. at the top with the android figure lying on the ground with an open stomach.

With the help of the Fastboot Tethered Recovery Launcher I can use the T3 option to change the device status to "fastboot-online". From what I understood I can then enter recovery mode if pressing volume up (so I can do a data/cache wipe) but it says

"could not open sys/devices/virtual/backlight" and I couldn't figure out what that's supposed to mean or how I can solve it.

I also tried to flash it again with the stock rom downloaded from here with the Intel Phone Flash Tool 4.4.4.

But that always failed at the "fastboot -s <device> oem wipe ESP" operation. It failed to execute that command resulting in a timeout only to try it once again. After that second attempt ended in a timeout too, it went on to the next step "fastboot -s <device> oem start_partitioning" but that also failed, ultimately making the whole flash process fail.

The curious thing (for me, anyway) was that I could flash the boot.img, system.img and recovery.img individually (by going to "Custom Flash" in the Phone Flash Tool and then selecting only one of those images) and all three processes succeeded. However, I only got the success message on the Phone Flash Tool, the tablet itself got stuck during the first reboot during or after the flash process.

In fact, every boot/reboot results in the tablet being stuck at the display of the Lenovo Logo. Nothing happens after that, it just stays there.

This happens whenever I try to boot normally or boot straight into recovery mode (Power + Volume Up). The only way I can boot my tablet and actually do something with it is the bootloader mode (Power + Volume Down) but as stated above, from there I didn't manage to get anywhere else so far.

Another thing I have tried is to enter fastboot mode because I read that I can also recover from there. But whenever trying to enter fastboot mode the tablet's display goes black, then a small text says "Fastboot starting..." and that's it. Nothing happens after that, no additional text or new screen.

What I also noticed is that whenever the tablet reboots itself or if I try to boot/reboot it, the tablet is not in the list of available devices anymore if I enter "adb devices" or "fastboot devices" in my command line (with connected tablet). Only when I redo the process with the Fastboot Tethered Recovery Launcher (option T3), can I access the device with those commands again (at first I could access it with "adb devices", later on only with "fastboot devices" and to be honest, I don't know why that is).

I actually just want to wipe the data of the tablet and install the stock ROM again because I think there's just some corrupt data that keeps my tablet from booting normally. But right now I don't even know how to do that because everything I've tried so far didn't work. Not even starting the tablet with the so-called "hard reset" (Power + Volume Down + Volume Up) worked, I only got a black screen in that case.

Because I tried to solve this problem myself all day yesterday, my tablet is now also down to about 20% of battery and I don't know if I can charge it up without a proper ROM installed (probably not). So that's another factor that's hindering me from trying out other steps.

I know this is a lot of text but I still hope there's someone out there who can help me with my problem. I am at my wit's end and would highly appreciate anyone who has knowlegde about this situation with this tablet helping me.

Best regards and thank you in advance
