    How do I know wich ramdisk version I have?

    I’m thinking about installing CM7 but I’m affraid of bricking it.


    • David Artiss says:

      This isn’t something I can advise on – you’ll need to follow the support links at the bottom of the article.

      However, I’d personally suggest you don’t worry. Follow the instructions and everything will be backed up in the case of a problem but the chances of failure is slim. If you do then need to do any kind of restoration then contact Graham and he’ll help you out.

    I get an assertion fault when I try to install the most actual version of cm7 (07.05.12). It fails checking for “A1_07″. Can somebody recommand me an version working?

    Hi Artiss

    I’ve rooted A1 to CM7 0401 before. Now if I want to update to recent builds like 0510, do I have to go through “Step 3 – Installing the modified bootloader” ?

    Or I just have to follow the below steps you introduced, thus no need to fuss over additional modified bootloader procedure? Thanks!
    “CyanogenMod doesn’t update itself automatically. If you want to update……”

  9. wolfesystems says:

    The link is still down to download the CM7 Rom, is there an alternative, or is the project dead?

      I experienced the same problem myself. However, I don’t have my A1 with me to give specific instructions.

      However, whilst in the CWM menu there should be an option along the lines of “Toggle script asserts”. Go into that first and you should now be able to install the update.

      I noticed in a recent changelog for CM7 that they’d changed the model number in it – I think CWM is thinking that the installation software is for the wrong model.


  13. xyz says:

    The cm7 rom that after 2012.8.15 must use cwm
    see here

  14. Karl Morant (from Canada) says:

    Hey, does anybody know where to find the changelog the the CM 7 Ideapad A1 builds? I see new builds about once a week, but I don’t know what has changed, or even if it is worth while installing.


  15. lee says:

    I dig your handy walk through here!

    I have an ideapad but the model number is “a1_07″ or “a1-07″ in various places in the documentation. Is this the same tablet? d’ya think this should work for for me?

    Have you also upgraded to cyanomodgen 9?

  18. chekote says:


    it looks like the link for the google update is broken.

  19. Vic says:

    Hi David, I’ve been trying desperately to install Clockworkmod on my A1 but to no avail. I renamed it just like you pointed out and put the zip on the internal sd card. When I get to the stock recovery screen it flashes quickly like if it’s going to go into Clockwork but it doesn’t. Any thoughts? Thanks in advance, Cheers!

      As I state in the article I can’t provide support – I’ve just provided the instructions. Please see the bottom of the article for details on how to get support – in particular the forum.

    Hi David

    Trying to install this but both ClockworkMod and CyanogenMod7 links return:
    The file you requested was not found.

    Your advise please.

    Many thanks in advance

    Thank you for your detailed guide; it saved me a lot of time when I had to flash my Lanovo A1 after several months/years, after my son managed to lock it by using repeatedly a wrong pattern in the lock screen!

    Even though some links are broken (after all these years), I managed to find the files and based on your clearly described steps I now have a fully working Lenovo A1 again!
