- option to use external SD card as storage for apps and media


Ok!!! Noted!!
Then I am complete with my flashing :)

However , I encountered some lagging issue.
once I boot to my main screen, when I go to Application drawer , I feel laggy when I swipe from page to pages.
and Also my camera is buggy, it lags when wanna capture a picture.

I feel like my whole tab is going not so smooth as expected. :(
Do you encounter the same issue?

I am using A501 btw.

Dear acer a501's users, I read many posts about this build and A501, but now I'm a bit confused. Can someone write a summary of what kind and version of bootloader should I flash to use this last build JB-MR1(4.2) - v13 ?

Now I tryed some bootloader and system builds, with older versions my tablet will boot without problems, but with these lasts build it go in bootloop :-(

My last few attempts have been with bootloader skrilax v8 and v9, with image 4.2-v13 and 4.1-v28. In all cases it goes in bootloop :-(

Where did I go wrong?

Thank you all for the help!

Despite of all the hard work, I managed to flash!!! Haha.. into JB4.2 V13!!! :)
the last thing I wanna do is to flash the kernal.

Is it same as flashing rom? Just put the zip into the sdcard, then Recovery Mode, then install from SD card?

Thank thanks!!!

it's 6.25am now, and I havent sleep for 24 hours d.. hahha


That`s good news :-) Congratulations :clap:
I`m glad to hear you managed to upgrade your boot loader, because it is a little complicated....
If you feel, your tab is slow, try to disable halo. Some users reported, it is not only ugly but it slows the machine down....
Play with the over clock settings, till you find an appropriate MHz for your device.

I'll try to help you :)
Mine was A501 everything stock before flashing, OS was ICS, bootloader ver 0.3.14 (You can check your bootloader by downloading Acer Recovery Installer) from the Google Apps.

1)Root your device. For ICS, it can very easily done with this link (http://forum.xda-developers.com/showthr ... ?t=1546593) by follow the instruction and download the right file
2)Obtain your SBK number of your device. Step 3 in this link. (http://forum.xda-developers.com/showthr ... ?t=1622425). Very important.
3)Next, get an unlocked bootloader. If your bootloader is ver 0.3.13 or 0.3.12 and below, you might wnana try the method in this link (http://forum.xda-developers.com/showthr ... ?t=1622425) else,
4)Follow method in this link (http://forum.xda-developers.com/showthr ... ?t=2400673) please navigate to post #4, about the "babsector.rar" content. Follow the small instruction box there commented by other user.
5)You should now have a rooted and unlocked bootloader.
6)Next download the ROM installed and GAPPS file from this thread, BOOT into recovery (By now you should see a custom recovery) and install the files from sdcard. Install rom first then gapps.
7)Done.

You have now a fully customized A501. Hehehehehehehe...

Credit to all the link provider, Medusa and uwra that helps me through!!!

Enjoy!!

Seems like 99.9 percent of users out there want to disable Holo.

Any knowledgeable people out there think we could rip it out by the roots with Titanium Backup or ROM Toolbox? and if so, any clue to the files we'd need to kill?

I'm DEFinitely one of those people - It's little logo sits there right next to Clear Notification in the tray and about 1 in 4 times my Big Ol' Finger hits that icon and re-starts the service, which Then makes me go digging to turn it off again...

Thanks in advance for ANY info...

OTHERWISE - I love the ROM. Finally made it up to v13...waited a bit for all the bugs to shake out - glad I did- but also Very Glad to be on the latest and Greatest from Thor...thanks again!!! Wonderful ROM!

No, absolutely keep halo, I love it and use it daily. Doesn't slow down my A501 at all.

You see, there are at least two opinions about halo 8-).

Why not keep it the way it is: include it in the ROM and allow people who don't use halo to disable it.

I finally upgraded to 4.2 and I LOVE IT!!! The only problem I have is with the google store. I ended up getting another random copy of gapps because this wont download. Right now the google store will not download anything, it just sits there like its about to download. I want to get ver2 of the gapps as posted in this thread but EVERY link stalls about 96% on everything I try (2 different pcs, 2 tablets, heck, even my phone). I am wondering if anyone has an alternate link to gapps v2? Thanks!

Try force closing the Google Play Store and Google Services and clearing data in each.

Yeah, I already did the play store and google services thing.. I just tried the download one, still wont download, just a blue bar with the little black specs floating along.. I was thinking I got a funky copy of gapps, thats why I wanted to try the v2 posted here.
