I'm running on Android 4.4.4 on my 3G 2012 Nexus 7 (KTU48P nakasig/TWRP tilapia), but having tried to do a stock revert on my system with NexusRootToolkit and the process locking into a permanent bootloop well beyond a good 45 minutes before I gave up and did a hard reset, I'm finding that the /cache partition is... gone. (The last time I flashed 4.4.4, it took the lesser part of 10 minutes.) I decided to drop NRT like a bad habit and try to fix the problem manually, but it seems like the tablet is bricked pretty badly. In Android System Recovery, I receive a scrawl that states: The Android system recovery <3e> menu also only gives me the options to "reboot system now", "apply update from ADB", "wipe data/factory reset", or "wipe cache partition". The device will not boot into the standard Volume Down+Power bootloader (the one that gives you the "Start"/"Recovery"/"Factory reset" etc. options in the hollow arrows) -- it simply boots straight to the system recovery menu with those four options. Trying to wipe the cache doesn't do anything. If I use the "apply update from ADB" option, the device opens up the debug bridge and my PC can successfully see it... but only in sideload mode, so I can't run fastboot. I can also call an adb sideload operation from my PC -- my top priority being of course to try to load TWRP. However, when I do so, adb successfully ships over the file to the OS, but I'm then given the scrawl: followed by the same scrawl block already shown at the top of this post, duplicated twice, and finally followed by: Since adb sideload is successfully transmitting the image to the device, rather than timing out, is this really indicative of a bad eMMC, or is there something else at play here? Is there some sort of other way to connect to the tablet and restore the cache partition without having access to the standard bootloader or the stock or TWRP recovery? I really, really can't afford a brand new tablet... and I'm already on the third mainboard I've swapped into this same case (and still the original battery goin' strong!) and 'twas a bitch and a half finding another 3G-enabled one as it was. =)

I have a Galaxy Note 10.1 and someone used it without my knowledge. I was only getting the logo screen so I tried to do safe mode and I couldn't get to it. So I tried vol up + power and get this: What did this person
do to my tablet? How can I fix this?

I suggest trying the "Hard Reset" again and see if it will work. I am including the instructions on how below. Should that not work, you may need to get the device looked at by a tech. The person may have rooted the tablet, tried to change the Android version, or another installation that they should not have done. NOTE: Doing this will clear 'all' the data on your tablet, so it
is suggested you not choose this option unless you have to, or aren't worried about losing anything on the device. Be sure you back up any data you want to keep, to a computer or cloud account, before doing the reset. To "Hard Reset" the tablet... 1. Make sure that the tablet is actually powered off. 2. Remove your SD card, if there is one in the device. 3. Press the "Power" and the "Volume Up" buttons, together, until you see the start-up logo on the screen. 4. Once you can see the logo, release the buttons and allow the device to enter the "System Recovery Mode". 5. Next use "Volume Down" button to get to the "wipe data/factory reset" option. 6. When in recovery mode the "Volume Up" and "Volume Down" buttons are how to can navigate and highlight what option you need. 7. Once you have selected the "wipe data/factory reset", press the "Power" button to select that option. 8. On the following screen, repeatedly press the "Volume Down" button until the "Yes - delete all user data" option is what is selected. 9. Then press the "Power" button to hard reset the tablet. 10. If you took your SD card out in step 2, when the device is up and running again, reinsert the SD card. Apr 6, 2016 25,142 261 113,340 14,334
