So I seem to have a unique problem. I have an old tablet by lenovo ( not sure of the model) which I got from an e-learning platform called robomate. So basically the entire tablet was locked down by surelock and the only apps I could access and see on the screen was a custom 'connect to wifi' app and the e- learning app.It is in perfect working condition. A couple of weeks back I decided to try and wipe the tablet so I could use it as a normal tablet. Since the entire tablet was locked down, I decided to try and wipe the tablet from the boot menu. I managed to get the key combination, opened the menu and got 3 options. I selected recovery mode expecting to see an option to format it. However, I get a screen saying 'command not found'. Any suggestions on how I can wipe it or re-flash android onto it?

Hello,
I own an Android tablet KO PARA1 FULL and experiencing a strange problem. This is a chinese atm7029 quadcore tablet (16gb, 1gb ram, without bluetooth, only wifi, bu supports 3g dongle), running android 4.1.1 nad 3.4.0+ kernel, which came prerooted. After some time I've decided to install backup programs on in to make a full backup of the device for the case something would go wrong, and after some trying I descovered, that there is something like recovery for that purposes which seemed a good solution for me. I decided to install CWM, which I managed to install without problems and made some backups on my device. Everything was fine, I did some factory resets through the time, some restoring processes from my previously backup states of the device, was always able to activate CWM recovery menu through Reboot to recovery or through combination of Volume down a Power button...
Until last saturday. I was normaly surfing the internet, reading mails and afterwords I powered my tablet off (it is draining battery in sleep mode, but its another story..). After a while wanted again to write a mail, so I powered it on. In that momet seemed the screen too dirty for me and I tried to cleen it little bit throug the bootup process. Unfortunately I obvious confused the system with it and after boot it was not responding properly. I did not wait enough and after a while powered it off with power key pressed for a long time, to make a new boot.
But when I powered it on again, it stayed stuck in boot logo and did not boot at all. I've tried a copple of times to boot it again with no cuccess, stayed stuck in boot logo for more then 10 min...
Afterwards I decided to make it boot up with the help of computer. I downloaded adb and drivers and somehow managed to make it boot up. I thing I was too excited to see it boot up again, that during boot up process I desconected my device from computer...
My worries were reliesed and I thought it would be a good idea to make a restore from backup to prevent some strange behaviour, so wanted to boot into recovery, but nothing had happened. After some repeated clicks on Boot into recovery button, as well as app called rebooter with nothing happening, I decided to try it out through button combination. It has not worked as well Next try was to reset to factory settings. But when I go through the menu, I can click on reset to factory settings button, seeing warning that I will lost ma data, then I can push the button to make it happen, but nothing is happening. I see only the screen with the button, can touch it 100 times and the tablet stays on, fully funcional. making no factory reset as it done before.
I did a lot of reading and searching, but have not find answer for my problem. I flashed recovery images from my backups (using flashify, flash gordon, adb shell, terminal emulator), from all previously functional states of the device. I refleshed the CWM recovery downloaded from the internet for my chipset, which previously did the job just perfect, with no success...
I am still not able to reach recovery menu. For me it seems like the bootloader would be locked, but I did not find the answer how to unlock it without to be able to start in some recovery state to use fastboot command to unlock it.
Otherwise, my device is functional, still rooted, i can use it without any other problems. But not be able to do recovery from my backups, even do a factory reset.
How can I restore my access to recovery mode? Is it somehow possible?
Hopfully it is not too much information (tryied to follow the intructions and wrote everything I thought would be important to know about) and you will not be bothered to read all my story and pull me out of my darkness with helpfull suggestion.
Thanks a lot in advance

Hello everyone,
I'm a bit crying right now, i hope you can help :-/
So, i thought about going to cyanogen on my tf201 some months ago. What i remember is that i unlocked it using the asus software then i installed some versions of twrp (i think). After that i stopped because i was kind of lost between many tutorials.
I did not use the tablet since that, i was abroad.
I get it back today and i tried to reset everything, so i went in the settings and click on the reset thing. It did not work, the tablet just blocked on Asus screen and when i manually restarted it, it was like i did nothing (normal boot and no reset).
So i went in the bootloader (power + vol down) and i tried the (4th?) option to wipe everything. The thing said something like "loading image ...." and blocked.
Now the tablet is blocked on the first screen (with asus writen in the middle) and it won't boot, i can not go into the bootloader either, i only have that screen.
I can not even shut it down, keeping power pressed will only restart it.
Is there anything i can do or is the tablet dead ?
Thanks for any help
Ok, here is the deal and I hope someone can help me. I have a cheap DigiLand DL1010Q tablet to play around with. It is stock, but I rooted it with KingRoot. There was a recent OTA wireless update and after it was installed it said that it needed to go into recovery mode to install and reboot. I selected install now and reboot. This is where my problem started and has remained. It loaded into recovery mode and is in an endless boot loop. I've tried rebooting it, recovery with the recovery file and every manual reset possible to no avail. DigiLand support said that I should power down the tablet, and while holding down the Volume Down (-) hit the power button and it will boot into a Chinese recovery mode. I've tried that and it just stays on the DigiLand screen forever. (I left it there for 8 hours.) I can sideload via ADB and the drivers are installed, but it will not let me load anything. It states that the bootloader is closed. I receive the same message via Fastboot. Now here is the interesting thing. Even after selecting the factory reset within the Recovery Mode, everything is still there. I have wiped the cache and partition and user data, but nothing really happens. It is still all there. I see the recovery file, but it will not load. All I see is NO Command.
I do have a sd card that I could flash things on, but it doesn't seem to register the card. It sees the sdcard, but that is the internal drive. How do I get it to look at the sdcard that I put into the slot? Is there a bootloader unlock? Does anyone have the factory image that I can put on my sdcard? HELP!!!!
I am fairly good with computers and have rooted phones and tablets before, but I seem to be hitting my head on a bricked wall - no pun intended. Let me know what programs, files or whatever. At this point I am willing to try anything. I can send it back to China for $50 for them to redo it, but I only paid $69 for it and I'm not going to put more money into this cheap tablet. I would just like to get it to work.
To start off, I suffered, what seems to be a common problem, of the fingerprint unlock on Samsung Galaxy S6 Edge randomly being unable to recognise my fingerprint. Followed by my back-up password not being accepted. Unfortunately, I turned off my data and wifi before the phone locked so the problem doesn't seem to be able to resolve itself unless I Factory Reset the phone.
This i am happy to do as long as I can find some way to retrieve the media files from the phone (just pictures and videos). I read up and watched some videos where some people were able to use ADB through Recovery Mode or Field Test mode, and pull the files from the phone. These people however were using older models of Android phones but I decided to read numerous pages etc and go ahead and try.
I set up everything (I believe) i needed on my Mac Book pro in order to use the Adb Terminal. However when I tried to connect my phone Adb couldn't detect my device. I then decided (after reading somewhere to do so) to press "Apply update using ADB" on the Recovery menu. Again, Adb did not detect my device.
i left this screen up on my phone which resulted in "dm-verity verification failed..." appearing at the bottom of the screen. It then switched back to the Recovery menu and continues to show "dm-verity verification failed..." at the base of the screen. Now when I try and power up the phone normally, the start up screen just repeatedly flashes and it goes no further than that.
Im not completely brain dead when it comes to this stuff but I obviously don't fully understand what I am doing, So Im wondering if there is a genius out there who, even after what I've done, can help me pull the files from my phone before I have to Factory Reset!
Afternoon
I have a Lenovo 7" tablet which is sticking on boot...to describe:
tablet off, charge screen working fine (green battery)
can get into menu to select fastboot mode or recovery
fastboot works, at least screen appears!
recovery shows dead android/no command screen - how to access recovery?
booting up, get inital orange logo then a 'bing' and start of boot but then freezes on the second logo
tablet not visible on PC, even in fastboot mode (have installed drivers)
I'm looking to get this going but am a bit stumped. I tried reinstalling firmware but can't get SPF Tools to work with any available scatter files; I would like to install TWRP (I found a potential image file on XDA) but can't do this until the PC recognises it....and I'm going round in circles now....any suggestions gratefully received. :good:
Update
OK, post was maybe a bit premature - I've kinda fixed my issues.
Managed to get into recovery after watching many videos (most of which were wrong, but hey-ho, got me on the right path!). At dead android screen, press and hold in power + vol up + vol down together (there is a bit of knack, turn it on its side with buttons facing up seems to be easiest) - this fires up the recovery screen (android standard recovery).
I managed to get over my bootloop issue by performing a data wipe/factory reset and cache wipe, then restarted fine.
As this was a secondhand tablet (my usual purchases - good condition bootloops!) - once it booted up I got into the set-up screens only to discover a Google lock issue. I ran the FRP unlock from here: https://androidfilehost.com/?fid=11050483647474832839 using the instructions from here: http://forum.gsmhosting.com/vbb/f958/lenovo-tab-4-7-essential-tb4-7304f-frp-remove-2322527/ (Voltrans second post, not the original one which has a 404 error on the download site). This removed the FRP lock straight off and now I have a functioning tablet.
I'm probably going to try getting custom recovery on so will see how that goes - I'll post back
and...that's all folks....
OK, despite finding a TWRP recovery online https://twrpbuilder.github.io/downloads/twrp/#441 and downloading it, can I get the fastboot unlocked? no.
Apparently Lenovo locked them all up and threw away the key, so nothing more can be done here.
I tried various iterations of fastboot oem unlock and fastboot flashing unlock, and nothing works, just get an error - and yes, I did put developer options on, OEM unlocking ticked and USB debugging active.... :silly:
So, unless someone can point me in a direction on how to unlock it - I've reached the end of the road with this one
