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
VFAT (extended fat)=FAT???

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 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.

Root is not needed. Just follow the installation's steps, this rom is the easiest to install!

You were right, no need for root, installation was a breeze. Thanks for sharing this rom, it's very fast!:good: Another question: can you recommend me a good music player app?

This tool is not meant to be used on Android devices with dm-verify or Android Verify Boot (AVB) enabled
Every Android device has a stock recovery installed. That default recovery typically at least offers you the 4 options
reboot system now
apply update from sd card
wipe data factory reset
wipe cache partition
thus you can place any valid update.zip in device's SD-card slot and update your Android from external SD-card.
Because being in recovery mode Android isn’t loaded, the Android system files are not placed in memory, which means they can be accessed, edited and replaced.
That fact allows Android users to enable ADB on their devices what natively support ADB, if they haven't done it yet, for whatever reason.
Download the signed ADB.Enabler.OTA.ZIP from here . IMPORTANT: Rename it to UPDATE.ZIP before you make use of it.
If you get error "Signature verification failed" means that OEM/Carrier blocked to flash a 3rd-party OTA. You would need to have a Custom Recovery like CWM/TWRP already installed and use that to flash the ADB.Enabler.OTA.

link not working

I am looking for zip that can enable usb-debugging and disable RSA keys without touching /data (encrypted/not mountable):
- boot.img
- system.img A-only SAR system-as-root device
I tried modifying build.prop and default.prop manually but it seems adbd is not running at all

got inspired by @ehteshamxa and created some flashable zip which does NOT modify system files. instead own files added
Code:
/system/etc/init/99userinit.rc
/system/xbin/99userinit_daemon
/sdcard/userinit.sh
/sdcard/rsa_copy
Instructions:
- install userinit-rsa_copy-flashable.zip
- install Magisk.zip
- copy adbkey.pub to SD Card
USE AT OWN RISK

is root required?

No root required. Magisk is recommended for easy avb/dm-verity disable, but of course one can also place the files manually by unpack/repack (simg2img/sdat2img) flash tool method.

optional:
- copy sqlite3 binary to SD Card
(get it from here credits: @DiamondJohn)
- copy Magisk-v23.0.apk to SD Card
(credits: topjohnwu you all know of course)
have added example code in userinit.sh that can authorize su permissions for adb shell. useful on broken screen in case one can't get scrcpy to work on boot-loop
(credits: @mirfatif for magisk.db injection)
rsa_copy works also from emulated storage if one edit the path in first line:
Code:
sdcard=/sdcard
on locked screen external MicroSD Card is only available location as MTP might not work. in that case place files from PC card reader and insert back
remember the whole purpose of that backdoor is inaccessible userdata partition, otherwise one could just add rsa_copy or 99userinit_daemon to /data/adb/service.d systemless-ly instead (or most straightforward inject /data/misc/adb/adb_keys directly).
once got su shell one can backup partitions, for example:
Code:
adb shell su -c "cat /dev/block/dm-0 2> /dev/null" > userdata.img

How To Root Samsung A01 (a015f/DS)
Hello, I want to ask how to root samsung galaxy a01 (a015f) , i want to instal f.lux for better blue light filter, Thanks!
forum.xda-developers.com
Thank you very much

1. Unlock your bootloader enter in download mode Vol+ + Vol- + USB conected to pc (Keep in mind that by doing this you will lose your files, it is advisable to make a backup of your photos, music, etc.)
2. Once you start your cell phone install magisk manager, Choosing the boot.img file of your rom into the app (Tip: Only!!! If your model is SM-A015M Android 11 I leave you my own modified boot.img to flash:
File on MEGA
mega.nz
Otherwise, you can download the firmware (3.79 gb) and extract the boot.img from the firmware of your model SM-A015 M / F ... Android 10, Android 11... etc. And No need for pc
https://samfrew.com/model/SM-A015M/
3. The image will begin to flash
4. When it restarts you will have Root on the cell phone!
------------------------------------------------------------------------------------------------------------------------------------------------
Extra: If you need the custom recovery I give you the link with my TWRP which is installed through the Odin program on a PC (this step does not delete your files)
File on MEGA
mega.nz
Keep in mind that to install TWRP you must deactivate the DM-VERITY & FORCEENCRYPT DISABLER I leave it in a link:
Zackptg5 - Android
zackptg5.com
This is a module that can be installed via magisk, which is necessary to decrypt the system ... so once TWRP is installed, it is advisable to uninstall it via Magisk to avoid R / W errors

Easy way to get Root & TWRP 2 in 1
A015F only!
Requirements: unlocked bootloader, android 11.
In Odin unmark autoreboot option.
Flash the "gorecovery.tar" file in AP field.
Boot to recovery and choose "Reboot system".
Allow Magisk to autoupdate.
If first boot after flashing will be into system - flash the file again.
The method keeps all your files and settings. Possible to use on already adjusted system.
