Sounds like your system is corrupt, and there is an update.zip left over from an OTA upgrade. When the stock recovery boots, it always installs update.zip then shuts down. Unfortunately the OTAs don't get deleted after installation, so if you ever get a problem, you can't enter recovery.
Here's what you need to do:
1. Download http://www.doc.ic.ac.uk/~grm08/ideapad/cwm-5.0.2.7-rev3-ideapad-a1.zip
2. Rename this file to update.zip, and copy it onto a micro SD card.
3. Boot up into recovery again. You'll see it do the same thing where it installs the update.zip and then shuts down, but this time it will install Clockworkmod Recovery.
4. Boot into recovery again. The Clockworkmod recovery won't automatically do an install then shutdown, you'll be given a menu instead.
5. First, try using the volume keys to scroll down to "wipe data/factory reset", and press the power key to select it. Try booting up normally again - this may have fixed your problem.
6. If this hasn't fixed the problem, get the 2643 zip file for your region from http://download.lenovo.com/slates/a1/OTA/ - copy this file on to your SD card, boot up into recovery, choose "install zip from SD card", then "choose zip from SD card" then choose the zip file that you just downloaded from Lenovo. It will install a fresh copy of the system, which should hopefully work after you reboot into the normal system.
If this doesn't fix it, or you get stuck, please post back with a description of what you tried and what happened.

In this situation you wouldn't expect the recovery to "work" in the normal way. After you've installed the Clockworkmod update.zip you'll have a working recovery again.

You didn't mention here but I saw in another thread that you attempted to use the leaked ICS installer which has messed up your A1.
If that is what you did, then you can look at these instructions for producing a bootable SD card that will allow you to boot into clockworkmod recovery and flash an OTA to get everything back to stock.

bootable SD card= linux required???
Can you help me?
I don't have linux - i install linux via virtual box

Yeah, you're going to have to install linux in a virtualbox. VFAT is built on top of the FAT filesystem.

If you read those instructions I gave, you'll see that there's a script called omap3-mkcard.sh that partitions and formats the SD card for you.

OK, thanks

I got a question, will I be able to move my apps from internal storage to SD card after doing the installation?
I'm currently using your SlimDroid v5.1 and it seems that I can't move any app to SD Card.
Everytime I move an app, it says 'Couldn't move app'.
Did I miss anything?
Please help.
Thanks!

One more question, I hope you don't mind. Where can I get CM? Is it an app that I can download from market or it is zip file that I need to flash?
I'm sorry for the noob question, I just started installing custom ROM for my A1.

Do you have a recovery there? Maybe try making a backup and flashing a root binary from a different device (galaxy for instance). I heard it sometimes works and if not you have a backup.
BTW - How is this device? Seems solid?

CWM RECOVERY and ROOT!

It says:
Not ALL images are correctly loaded, which may cause boot up issue!
Do you still want to go on downloading anyway?
Any ideas what to do from here?

Thanks for the offer. I've sent the phone back

CWM Recovery & Root
I have successfully flashed a CWM recovery and root script on this phone. Everything works. Here's how its done:
Here is the "About" under settings on the phone that i have done this on:
First Download This:
http://www.mediafire.com/?eq9b28ua89wh8d1
This RAR Archive contains everything needed.
MAKE SURE YOUR PHONE IS ON JELLYBEAN. [4.1]
1: Installing CWM Recovery
Extract the downloaded zip and run the flash tool. (Flash_tool.exe)
In the flash tool, click where it says "scatter-loading", and browse for "MT6577_Android_scatter_emmc.txt" [It is in the: \CWM_recovery_4.1\recovery folder that was included in the downloaded archive]
Now, before flashing, MAKE SURE "RECOVERY" is the only thing ticked in the list of things to flash.
(Mine had two things ticked by default, just make sure the only thing that is ticked is the recovery.)
When the scatter file is loaded and only recovery is ticked, make sure your phone is off and the battery is out. Also make sure it is unplugged from the computer.
Now in the flash tool, click the download button at the top.
*Note: If you get: "Not ALL images are correctly loaded, which may cause boot up issue!
Do you still want to go on downloading anyway?", Just click "Yes"
Plug in your phone with the battery out and wait for it to finish flashing. If the flash tool doesnt detect the phone, it means the drivers probably aren't installed. install the drivers [included in download (MT6575_USB_VCOM_drivers)] and wait for it to finish flashing
When it flashes, you will get a popup window with a circle, showing that it has completed. you can now unplug your phone.
CWM recovery is now installed on the phone. Time to root!
2: Rooting VIA CWM Recovery
Copy the "CWM-SuperSU-v0.93_tirannozaurus.zip" to your phone's SD card.
Boot the phone into recovery. [hold volume+ and power while the phone is off]
Choose "Install zip from sd card" [using volume and power buttons] and navigate to "CWM-SuperSU-v0.93_tirannozaurus.zip"
Flash it, and then reboot the phone. You should now have root:
If you follow all of this properly in order, this should work! i am not responsible for anyone bricking their phone. Doing this is all on you.
*NOTE*
If your play store is not working [If it says there is no connection], Goto your phone's settings and set your date and time. This fixed it for me.
Also, credit to the original authors of the files. I have simply taken the required files and archived them for your convenience.

I think that you need to flash miui rom, and after install the recovery ask to you if you want to flash the Mirecovery
@thebrainkafka I try to enable the TDB, but the recovery don't ask to me if i want to split the data!! In this way I have one data for two ROM and the system app like clock, browser give me an FC on the first ROM

Not working on my mi 4
It fails to install on my mi4. i have renamed it update.zip on the root of the mi 4. if i select it via the updater app it says update failed error and the same on the stock recovery.

If you're having issues with the new R11 then I suggest you flash R8. It's been working fine for me.

You can use an app as flashify or rashr,
Before you have to extract the recovery.img from the zip file and put it in your sdcard.

How to Install Custom ROM on any Android Device
CONGRATULATIONS! YOU HAVE SUCCESSFULLY INSTALLED CYANOGENMOD ON YOUR TABLET!​huge thanks to DavidRGX for making this custom ROM

First of all, big thanks, it worked without any bugs.
However, it's honestly going slower for me than the stock rom, system it's taking up to 750mb of ram which is way worse than in stock rom even with a bunch of moderately heavy apps like youtube, and a faster even if marginally rom it's exactly the point here, do you know what might be causing it?
https://forum.xda-developers.com/t/...iple-swap-space-in-cache-data-system.2145133/
Would that work with this tablet and rom?, i have a working backup so i'm not trying to be a toxic dude who's blaming you for my own irresponsability.
By the way, i had apps moved into external sd in stock rom, they don't show up in apps manager right now as it was expected, but could that be causing some kind of conflict?
cheers mate!

Ok, for anyone having issues with the ram, scroll down this thread https://forum.xda-developers.com/t/cyanogenmod-12-1-lenovo-tab-3-710f-unofficial.3771079/
There`s a patch for the ram memory leak with instructions, it works

I am unable to boot in TWRP after flashing it through SP tool. It bootloops and start in stock rom after that it shows stock recover
