I used Unlock Root. Simple, fast, free. http://www.unlockroot.com/
[Miscellaneous Android Development] tinybeetle:
Dogpuke1, look for A1_Rooter.zip and CWM or Clockworkmod Recovery. Your answer for obtaining root lies in using those two tools. There is plenty out there on the internet on how to do this.

Basically: get a1_rooter.zip, put on microSD. Get CWM ver 6 and put on micoSD as update.zip. Boot the tablet from the microSD into CWM, apply the a1_rooter.zip file, reboot. You're rooted.
[Miscellaneous Android Development] dogpuke1:
Wasn't sure that would work on ICS update same method I used on stock ROM before ICS
[Miscellaneous Android Development] tinybeetle:
It works for ICS. I used CWM version 6. I don't know if a lower version will work.
[Miscellaneous Android Development] buddn07:
Worked ok for me.
[Miscellaneous Android Development] dogpuke1:
That Worked!

Could Not find CWM 6.0 for Ideapad A1 ....Ran CWM 5.028 it worked just fine, Root went in smooth! Thanks, for the input! Wasn't sure about ROOT after OTA update..... Tablet runs like silk now!

I faced so serious battery drainage issue with the official ICS 4.0.4 ROM that I had to go back to CM7 2.3.7 last night. I kept loosing almost 30-40% even if the device was in the airplane mode, with all radio disabled...

Even though I loved the new interface, I would never go back before Graham and the rest of the people working on CM9 provide even a beta version (which will anyway be much better than the official one!).
[Miscellaneous Android Development] jpisini:
Try Gingermodspeed battery is really good.

[Miscellaneous Android Development] Captain Hilts:
Is anyone having problems with wifi staying on during the sleep state with ICS on the A1? I have gone into advanced setting and have checked it off to keep wifi on at all times, but it still seems to disconnect after a while when the screen is off. I have tried one of those Wifi Keep Alive apps in order to fix it but it hasn't worked.
[Miscellaneous Android Development] Captain Hilts:
Regpon Wifi Keep Alive from the Play Store seems to be helping so far with this problem. I also read on another forum that the OTA update (that kills the soft key backlights) seems to fix it as well.
[Miscellaneous Android Development] punk_zappa:
I've had the ICS port for about 3 months now. Battery drain is a constant issue, just lost 30% overnight with wifi to only stay on during charge. Power shutoff (on its own) is a constant struggle, too. Sometimes I will put the tablet to sleep and would not turn on the next morning or after a few hours. I did factory reset and reinstalled ICS a few times but the issues are persistent.

SO I decided to try gmark's instruction using the img files but I tried to wipe using davlik too. Upon reboot there was no more access to CWM in the SD and also, no more stock recovery. The box with the arrow and android shows up for about 5 secs and tablet will just shutoff.

Once on ICS it would still read the SD card. So I am not really sure what is going on. If someone can please help me get back the stock recovery so I can just return to Gingerbread. Thanks.
[Miscellaneous Android Development] jpisini:
Do you have 16gb or 2gb tablet?

For WiFi use WiFi keep alive. Under advanced options checking option Two works for me. Drains battery though as it prevents deep sleep. I use airplane mode when not online.
[Miscellaneous Android Development] punk_zappa:
I got the 16gb version. I don't mind the drain as much as the reboots.
[Miscellaneous Android Development] jpisini:
OK check out my post here http://xdaforums.com/showpost.php?p=27181317&postcount=1127 you are going to need the stock mbr zip. Then go to http://www.doc.ic.ac.uk/~grm08/ideapad/cyanogenmod/ grab the stock-a1-ramdisk-2643.zip then go to http://download.lenovo.com/slates/a1/OTA/ and grab A107W0_A234_001_015_2643_US.zip or if you are elsewhere in the world the ROW.

Now make sure you have CWM 5.0.27 from http://www.doc.ic.ac.uk/~grm08/ideapad/ boot into this and flash in the following order

stock mbr reboot into CWM (needed to repartition)

ramdisk

US zip

This is how I go back to stock and from there you can install CM7, GingermodSpeed, or Miui.

This works for me, it doesn't hurt to have a bootable sdcard if you have a spare check out those instructions it has saved my behind on a few occaisions.

But, I found this, http://xdaforums.com/showpost.php?p=26961316&postcount=54. I wll try it in the morning.
[Miscellaneous Android Development] jpisini:
If you are having trouble getting in to recovery that will help. Gmarkell also posted how to build one at the Lenovo forums I have used both and they work.
[Miscellaneous Android Development] punk_zappa:
It's a no go. Tried booting with bootable iso, hard keys lit up but no image. Anything else to try? I might have deleted the recovery when I did the wipe.

EDIT: OK, got it working and back to stock now (I just had to keep pressing the volume - ). Recovery is also working. Thanks.
[Miscellaneous Android Development] jpisini:
Are you sure you created the sdcard right? While not impossible the A1 is very hard to brick.
[Miscellaneous Android Development] punk_zappa:
I'm back to stock but internal storage is only 2 gb, I have the 16 gb version. More reading I suppose.

question about text and icon size ?

is there a way to change the text and icon size that i have missed in the posts ? ..

everything is so small, which is fine when it comes to the icons and everything else . . but typing is quite the (female dog) .. with my fat fingers ..
[Miscellaneous Android Development] jpisini:
I grab a DPI changer from the store and set it to 200 that is great for my eyes. 160 I'd the cm7 default. You can try others but make backups first as it could prevent booting.

You can also use spare parts to change font size but not icons.
[Miscellaneous Android Development] DroidZombie:
My A1 is still on CM7 and my phone is on CM10 so I'm not sure if this is correct, but there should be an option to change text size under system settings/system.

I'm running ICS 4.0.4 stock on my daugther's Lenovo Ideatab A1 (16gb) and I'm having trouble with Youtube App. HD videos and ads won't play....they just time out and I get the following error message "There was a problem while playing. Touch to retry". Any thoughts? Is there another Youtube APK that I can install? I've tried uninstall and re-installing, clearing cache and data and no luck.
[Miscellaneous Android Development] geoponer:
Just rotate the tablet in landscape mode and disable HD from the top left corner icon. This solved the issue for me. It seems that HD videos are not supported by the tablet or this version of the ROM.
[Miscellaneous Android Development] drozda:
It depends. Looks like someone has access to sources from Lenovo cause wifi driver and GPS setings are same as on stock 2.3.4 ....

Well Lenovo is second tablet supplier in China so they should be carefull when releasing new versions .... imagine 10 milion angry customers when something went wrong with new update :)
[Miscellaneous Android Development] Tint Ag Khaing:

[Miscellaneous Android Development] drozda:
Looks like you have corrupted recovery image in tablet now.

Now you have to prepare boot SD card and add recovery image or CWM with update.zip and boot into recovery (CWM) from SD card.

Then just flash proper update.zip

All information are here on xda in proper threads.
[Miscellaneous Android Development] Brancaleone:
That's what I told. Only solution is to boot cwm from sd.
[Miscellaneous Android Development] isime13:
Actually, I still think the most easy way to test this ROM is: Replace CWM with stock recovery, then apply the first ICS update.zip and finally the second ICS update.zip. There is no need to use CWM at all to test this ROM.
[Miscellaneous Android Development] unplugged138:
1、Make bootable sdcard without linux , download the tools leaked by lenovo : http://115.com/file/clykyncr

in the download page ,choose the "普通下载",unzip it with password:bbs.lenovomobile.com, run the "burnin1.exe" program,choose CL1_1.09B_for_5 in "img file path" , click the "Burnin" button ,then the program will fdisk and formate the sdcard,get a fat partition named "boot".

2、 download http://www.doc.ic.ac.uk/~grm08/ide...ideapad-a1.zip , unzip it 、 copy the recovery.ub file to the boot partition and rename the file to "recovery.img".

3、insert the sdcard to lepad A1 ,and try to boot A1 to CWM.

- can i root it?

[Miscellaneous Android Development] Tint Ag Khaing:
Pls help me !!

Wooooo... Now i think i've a problem here... :(

So... My lepad A1 is now running on the very first leaked unstable ICS build and last weeks, i flashed back stock recovery downloaded from CWM download page and flashed back to use the another Update.zip available in ICS download page.

SO....THE MAIN PROBLEM is this stock recovery isn't updating the Update.zip that i put into external 8Gb SD card.

So I want to flash back CWM and put CWM ( update.zip ) in external SD card again and this also isn't working. So I don't have a working CWM in my A1 yet!

I think this is because i put update.zip in exterrnal SD card and i tried to connect with USB to computer but the computer isn't getting to know the internal SD card. So what should i do brothers ? How can i flash back to stock ROM. :confused:
[Miscellaneous Android Development] drozda:
Create bootable SD card - put either CWM recovery image or stock one and you can flash anything you want.

Download http://www.mediafire.com/?m76r7t0vrbvj213

and http://www.mediafire.com/?on3orn8zyb8y0hn

Unzip first file and then use the second file to create the bootable SDcard using a card reader to add the image to the SD card.

Once you have added the image insert SD card into the tablet and power on holding volume down button this will put you into recovery.

Now install zip from SD card install cwm-5.0.2.8-ideapad-a1.zip

Now you will be able to boot into recovery without sdcard, so you can format sd card and add the rom of your choice. GOOD LUCK!

Impossible , this device can't be bricked totally. Read the whole thread again , create bootable sd card on linux (you can use any current live distro on CD) and copy recover image into.

Then just boot with update.zip inside.

Seems like there is a new leaked version of ICS for our A1.

Link to german forum:

http://www.android-hilfe.de/lenovo-ideapad-a1-forum/250004-p-ics-1-2-kommt.html

I didn't try it and can't say anything about it but wanted to inform you :)

UPDATE: I couldn't resist and just installed it. You have to install it from an external SD using the stock recovery. The sound is a bit messed up (constant whisteling and it sounds horrible at too high volume) but apart from that it seems quite usable.

There seems to be a problem using the external SD but there is a zip that fixes this issue in the german forum:

Not coming out of sleep.

I've updated this. It's not coming out of standby. I have to hold the pwr button down for ages and ages to get it to pwr up again.

Also, tried putting cwm .25 back on it again so I could re-root it, but it does not seem to have installed becuase it is still the stock recovery.

I also have to press what seems like VOL + & PWR, instead of VOL - & pWR to get any kind of recovery on screen.

bootable CWM

You will have to use one bootable sd Card to get out of that trouble.

Because the most of people don't have a Linux Distribution installed, I made one iso File to help you start CWM from SD-Card without having a Linux.

Follow those Instructions to do that:

1. Download Win32DiskImager.

2. Download mine A1_BootSD.iso

3. Plug one micro SD-Card (it would be formated later on!)

4. Start Win32DiskImager.exe

5. Image File: A1_BootSD.iso , Device: your SD-Card and use "Write" to start

6. Put your SD-Card in A1

7. Start A1 with Power and Volume(-)

Also, forgot to ask. Where can I get the US factory recovery image? Do I install it with CWM? Thanks for answering!
[Miscellaneous Android Development] xbdesign:
You can take this stock recovery and flash it with CWM.
[Miscellaneous Android Development] thebreezer:
Perfect,*booted in CWM with your method, but now, when I take out the sdcard to put the recovery image you proposed, I can't boot back in to CWM with power-, I get back to that android with the box!:mad:
[Miscellaneous Android Development] kryszan:
When you put the stock recovery, the CWM is removed. Now you have to install CWM via stock one...

There can be one recovery installed at the time.
[Miscellaneous Android Development] thebreezer:
Don't understand.
[Miscellaneous Android Development] xbdesign:
No no, just copy the recovery I sugested to the external boot sd card that you made.

So that way you can flash it without puling a sd card out ;-)
[Miscellaneous Android Development] thebreezer:
Right, stupid me! But just did that, but upon reboot all I get is the Lenovo logo in a loop.
[Miscellaneous Android Development] xbdesign:

- CM

- ICS one more time
[Miscellaneous Android Development] thebreezer:
I want to go back to stock ROM.

By the way, thanks for your patience :)
[Miscellaneous Android Development] xbdesign:
now i understand.:-)

so you just have to copy a stock Rom to your Boot sd and flash it from there.

AT the beginning you asked me where to find us stock recovery., so i gave you a link for that,

but you actually need stock Rom.

---------- Post added at 12:18 AM ---------- Previous post was at 12:06 AM ----------

here is the latest us stock rom

After flashing it wipe data/ factory reset from cwm!
[Miscellaneous Android Development] thebreezer:

[Miscellaneous Android Development] thebreezer:
Ok so I made a boot sdcard with the .img you gave me before, no problem. But when I want to put the stock rom on it, there isn't enough place, since win32diskimager formatted my 8GB sdcard to 62.9 mb!
[Miscellaneous Android Development] xbdesign:
O.k so you would just have to put a CWM install zip on your boot sd and flash it.

Then remove a boot sd and start a flashed CWM.

From there you can flash your stock rom if you put it on normal sd card.
[Miscellaneous Android Development] thebreezer:
Excellent, I will try this morning. Fingers crossed.
