[Q] What to do with PB liberty tab to have ICS

[Q] What to do with PB liberty tab to have ICS - Acer Iconia A500

Hi guys,
I've a rooted Liberty Tab with Acer A500 HC 3.2.1 and a full nandroid backup to go back to PB stock ROM.
I would like to update to ICS, but I know that ICS requires a new bootloader, and as far as I understand, it's not possible to revert back to HC bootloader.
Is this right?
The first choice I have is to update my tablet with a modded A500 ICS rom, and I will loose (forever) my PB HC bootloader.
Otherwise I can go back to stock PB rom, accept PB 3.2.1 update and wait for PB ICS OTA (does it exists?)
Any other suggestion?
Is it stable to use ICS with HC bootloader? I didn't understand if it's ok or it's only a workaround but not stable.
Many thanks!

Hi,
you can use, as an example, the Flexreaper Rom with the HC Bootloader without any probs. The Rom has an autodetection for the bootloader and installs the right Kernel accordingly.
I did this from the beginning of the Flexreaper Rom until last R12.5.
Last week I decided to change the Bootloader to the ICS V3 patched. The same way I installed the V3 pathed ICS Bootloader, could be used also to flashe the HC bootloader back. But as mentioned, not really needed.
The Flexreaper Rom is excellent, give it a try.

[Q] bootloader version - how to change / upgrade ?

Hello,
I bought an acer A500 which was under HC 3.2, may be 3.0.
I have rooted it, and tried some ROM.
I used this tuto :
http://forum.xda-developers.com/showthread.php?t=1307539&highlight=root+without+downgrade
after few ROM test, I have choosed, for the moment, the latest flexReaper (1.031...)
I have Acer Recovery, which allow me to reboot easily in recovery mode.
now, after reading several post here, I have few question :
how can I know if my bootloader is HC or ICS ?
how can I know the version number of this bootloader ?
can I change the bootloader to another version , keeping the actual ROM ?
can I install a new bootloader with CWM ?
I have a CWM rev 1.3.4 by thor2002ro. is it good ? there is better than this ?
is the bootloader able to change the performance of the tablet ?
or just the kernel / Rom can do it ?
many thank you for any answer.

If you haven't flash an ICS Bootloader, or a Stock ICS Beta rom, then you have a stock Acer Bootloader.
To change bootloaders, you generally run the bootloader.zip through CWM/RA immediately after installing the rom, according to this post;
http://forum.xda-developers.com/showthread.php?t=1517181
You have an old CWM recovery. You can either goto Tegraowners and upgrade to a newer version, or Flash RA Recovery from here through your current CWM

Your choice.
Kernels generally change the performance, although a well coded rom also plays a factor.

If you have Acer Recovery Installer v2.74 it tells you what bootloader version you're running, as well as the recovery version.

Hello,
just to be sure :
>stock ICS beta rom :
are more for developper, isn't it ? I read in some post that it was for development only.
flexReaper, Tabooney Icylicious are not stock ICS beta ??? isn't it ?
> or Flash RA Recovery from here through your current CWM
I have installed acer rovery installer 2.74 from the market.
with that, I have flash clockWorldMod recovery rev 1.3.4 by Thor2002ro.
under this tool, I can see : bootloader version 3.01
my rom is the latest flexReaper.
what do you think of that ? can I upgrade or do something better ?
thank you for any help.

If you would open a rom.zip you would see that the custom roms got no bootloader .blob and recovery to be installed.
That is so you would be able to flash without problems what you want.
Flexreaper, Icylisiuos , Lightspeed, and taboonay are all custom roms that can be installed with cwm or ra recovery and now the new twr recovery.
What is the best custom ICS rom , well all custom roms on here have there quality and is more up to the user what he or she wants.

ok, so I will look for bootloader more update than mine in this case.
the Rom Flexreaper I use during few days works very well, and now I am looking for the best bootloader and kernel to work with taht rom
anyway, good point, I should have look inside the zip file of a rom !
thanks

You don't need to update the bootloader. It will make no difference in the performance of the kernel or ROM. If you do update the ICS bootloader, you'll need to udpate the kernel to work with it and you will not be able to go back to an HC based ROM.
Just keep your 3.01 bootloader and use custom HC or ICS Roms until Acer releases ICS.

Hi
Well this helped me.
Because of all these terms are confusing in the beginning.
And a lot is all spread around this forum.
For noobs like me some terms like bootloader and wath to watch out for should be stickyd.
Well up to next page of reading hehe
Thx

[Q] Leaked 4.0.3 ICS Back to 3.2.1

I installed the leak after getting pissed about how long it took to get ics and how terrible honeycomb was. The leak has been incredible and made my tab sooth as butter... However I am afraid I won't get the official update which hopefully will be patched to include the ring.
How can I flash back to stock 3.2.1? I have I have looked all over and haven't seen a clear cut solution
Thx

if u r on hc bootloader all things bein equal then try a nand restore - worked for me.
if it doesnt or u on ics bootloader then its an EUU/manual apx downgrade procedure.
i've since flashed flexreaper, acer ring works perfect and so i'm sticking with it till the furore dies down and acer have their rom stable

Go here, http://forum.xda-developers.com/showthread.php?t=1816560 , download the EUU for 3.01. Put you tablet in APX mode (make sure your computer recognizes your tab as an APX device) and reflash. There are lots of posts that will tell you how to flash an EUU. Most important, make sure you have your CPUID. You will definately need it. Once you have reflashed stock 3.01, you can go to the market, update literlly about 4 or 5 times, and you will be back to stock 4.03 ICS, or lower if you choose to stop upgrading sooner.
Much easier to flash a custom ROM, especially since you already have the correct bootloader. Have youvtried re-flexx shellshock?

Thanks a lot for answering me and for the Re-flexx shellshock i don't even know what it is sry I am a newby in those stuff I will try what u said hope it works.

[Q] ICS Upgrade

Hello XDA Users, I have a very basic question regarding my ACER A500 upgrade. So far, I have tried every single avenue to upgrade my tablet to ICS but nothing worked. I am not sure, is this because of current HC ROM with ICS unlocked bootloader, but every time I flash any ICS ROM, I am stuck at booting primary kernel message from (V8 unlocked ICS bootloader) or ACER boot logo. But if I flash HC full ROM (3.1/3.2), everything works just fine. Some may say this is a repeat post, but I didn't get any answers from my earlier question, so decided to rephrase the question in simple manner.
At one point, I had ICS ROM successfully running on tablet with V8 bootloader but one fine day it decided not to boot up at all. And I have to go back to basic using TDV4.
Now I am on HC Rooted ROM with Thor CWM based recovery and V8 bootloader. If you need any further details to get me on ICS, please let me know.
Thanks
