[Q] Custom Rom Upgrade / Downgrade - Acer Iconia A500

Hi pp.
I have a question about applying custom roms. I have my A500 with Virtuoso Galaxy which is 3.1 based and i want to know if its safe to switch to a 3.2 based rom.
It's necessary to do something before? Or I can apply the rom via clockwork without doing anything? (I've already did a backup from my stock)
Sorry for my English, I know its horrible xD!

Yes, just wipe in CWM and flash it doesn't matter what you had before.

Great! I did it without issues. But, now, just to know, It's possible and/or safe to downgrade to others roms from 3.2 to 3.1?
Thnx!

Since you are rooted then yes, it is completely possible to downgrade to older ROM.

Yep, You can pretty much move between roms (3.0-3.2) freely now. Just make certain you wipe before flashing new roms to lessen the possibility of hang-ups or issues with new roms. You can also try different kernels too just make sure they are compatible; most devs will post compatibility in the thread. Hope that helps.
Enjoy!

Upgraded 3.2 Rom

Now that i have upgraded to 3.2 with the primee P-9 rom,can i still use the other roms that are 3.1 without having to downgrade or unroot?
Yes. Just make certain to wipe through Clockwork before flashing new roms. You won't have any issues (even going back to 3.0). Hope that helps.
You can install any rom regardless of what you have installed. Its a complete replacement. You can't use two different Roms at the same time. Ie.. you have Asus 3.2 now. If you install taboonay, you'LL then have 3.1

Downgrade 3.2 to 3.0.1 AND root help

i dont want to have my hand held every step of the way so i will try to outline what i believe i need to do and hopefully someone can confirm and correct me.
here goes....
first use this method, apparently method 2 better, to downgrade...
http://forum.xda-developers.com/showthread.php?t=1276227
i then need to follow a process to either root it and leave it as 3.0.1 but rooted or install a custom rom that is rooted? if i need to install custom rom due to that instability mentioned in method 2 i could just put a stock but rooted 3.2 i believe. is there a list of rooted 3.2 roms that i can just install without playing around with kernels or whatever? which is the best currently?
thanks guys and please be gentle
I used the downgrade to 3.0.1, root that, install cwm by thor, then for now flashed Taboonay.
I too am looking for a Rom that fits me right. I'll report back if I find it.
<warning>**** I Void Warranties ****</warning>
cheers mate. idecided to use method 1 and it went without a hiccup. i then rooted.
for now i will leave it with stock 3.0.1 rooted as i am sure ice cream sandwich will be out in a short period and then i will look to put a rooted version of that on when it is known to be stable and someone has a good tutorial on it.
thanks for all the work that goes into the development of this great OS.
one of the reasons i wanted to root is to increase cpu speed.
when i just installed setcpu it wont allow me to go over 1000mhz which i presume is to do with the stock rom.
any suggestions? does this mean i will HAVE to install a custom rom, if so is there a list or any roms that are definitely better than others? if so, i guess there will be different procedures to install depending on the rom,?.
Not necessarily a custom rom, but a custom kernel. Some roms include kernels, some dont. Any you can install kernel wthout rom if you want.
I used method 2 and downgraded to 3.0.1. This version is very unstable as I got a force close message every 5-10 seconds. I immediately rooted using iconia root. (Iconia root and the rom that I was going to flash were already on my sd card prior to going through the process) Kekinash has a rooted stock rom here in the development section if that's what you want. I downloaded it, but I have not flashed it yet because I am happy with Thor's current 13.2 rom. There is a link to Thor's website in the general section. I won't post it here because of xda rules. I can't speak for any other roms in this section because I only ran rooted stock before the 3.2 update.
Lightspeed Rom is pretty snappy
cheers guys, went with honeyvillain.
only probs: first it says to insert a sim card, as i have a a500 it doesnt use a sim card, this is probably why 2 force closes come up straight away for system updater possibly?
second, the market kept saying there was an error. i uninstalled the market and found the latest market apk and all is fine so far running 1400mhz.

How doi I get to ICS?

In December, when I picked up my TF101, I used Razorclaw + CWM to root it. I also found some kind of an update here that I applied that allowed me to overlock the device .. I believe it was a form of kernel patch?
I would like to go to ICS. I need to be rooted after ICS though, we have a VPN client for our SonicWall firewall that requires the OS to be rooted. I would also prefer an ICS port that supports overclocking like my current build .. it's been incredibly useful to clock up in to the 1400s as it makes everything run so much better.
Is it possible to upgrade to the stock ICS, root it easily and patch it to allow for overclocking at this time? If so, could someone direct me to a guide that shows what the easiest way to do this is, since I already have CWM in (although can't remember how to get it to come up on boot .. doh)?
Thanks =)
Wait till Asus fix the problems.
Yea dont install ICS, it would be like pouring water over your PC
It might seem fun at the time, but its really not a good idea
I would say it is a very bad idea. Avoid it. I did it and literally my tablet is unusable now because of
Slow response
Random rebooted
Random no message crash of apps like gmail.
Dead slow,app response
white screen on app loading
It is now embarrassing infront of ipad users.

Ignore the fear mongering posters.
Tons of people are using ICS without issues. But yes, some do experience issues.
Since you have CWM, you can directly flash the pre-rooted stock ICS. http://forum.xda-developers.com/showthread.php?t=1552303 This is the latest 9.2.1.17 version.
If you want to overclock, you can flash custom ICS ROMs that support overclocking. There's only 2 at the moment, Team EOS and Codename Android.
Frequently updated custom ICS roms such as Team EOS and CM9 tend to be very stable and have fixes that stock ICS doesn't have, so flash a custom ROM instead of the stock ROM if you are concerned about possible issues.
As always, do factory reset + clear cache + clear dalvik cache within CWM before flashing the stock ROM or any custom ROM.
To be safe, I would update your CWM to the latest version here http://forum.xda-developers.com/showthread.php?t=1213723 before flashing anything.

Terrible advise.
Why tell someone to update to an OS that has literally flooded XDA and other forums, and ASUS's facebook page with people saying their TF is no longer usable ?
For the sake of waiting for a working update, why suggest doing something that could very well turn their TF into a buggy POS ?
There is nothing in ICS that is worth the risk

There are just as many people, probably much much more, who aren't having problems.
Besides, have you tried any custom ROMs? If not, stfu.
I would no say my TF is unusable under ICS.
It works fine, apart from not so random reboots, as it reboots mainly in the morning when I wake it up form the night...
maybe the Sleeping Beauty requires a kiss from the Prince ...
By the way, it used to be really better under HoneyComb, I wish i could have refused that damned firmware upgrade ...
If I were you I'd rather wait as an other poster said for a really proven Stable version from Asus

If you are using one of the better custom ICS roms and still having such bad issues, the problem is you and your apps since those AOSP roms aren't even based on Asus's ICS.
The OP has root and CWM, and wants to overclock. So how was it a bad advice to recommend a custom ICS rom?
Just because you are having issues, doesn't mean everyone else will.
I've never had any issues at all and I just got done testing like 5 different ROMs. No issues whatsoever. Probably because I do it correctly and do a full wipe including format /system before I flash anything.
I've got issues on Stock and I did a full wipe using voldn+power method and this was before I rooted. I also lost sound randomly on Stock, and the custom kernels I still get reboots but my sound for the main part does work.
So, if the OP needs their tablet to work correctly then wait, if it's not that important to them and they don't need for day to day tasks then take a chance, you might get lucky or you might be causing yourself a headache, up to you.

How is the problem me when I am doing everything the "ASUS way" ?
The problem is ASUS and their code.
If you read the OP's actual post, you will see this line
"Is it possible to upgrade to the stock ICS"
And if you want to go even further into it, your line "Probably because I do it correctly and do a full wipe including format /system before I flash anything"
I don't think you can get a cleaner flash than NVFLASH, which is how I always flash my ROMs

[Q] Another reverting question...

I'm tired of looking for an answer to this seemingly simple question on google and searching on here. I've had at least 5 tabs open for the last hour combing through posts and replies.
Question is this: A500 running thor's v14.2 rom along w/ his custom kernel. To revert back to stock. Do I need to flash back to the stock kernel along w/ the stock rom. If so, where can I get the kernel from?! The closest thing I came across was a post that gave the source link where you had to build the kernel yourself.

did you make a nandroid of your ROM before you flashed the current ROM youre on?
of course not! lol. I was too excited to play around w/ it that I neglected the basics. And honestly, I've been putting off reverting back because I'm quite happy w/ thor's rom.

good luck bro!
I've also decided to head back to a stock ROM in both anticipation of the ICS update and to try and get video working with Skype. My problem is, I'm using a A501, which seems to be the unwanted red headed stepchild of the Iconia family!
I'm on a custom ROM (Moscow something-er-rather?) with CWM. Do I just find a copy of the stock ROM and flash like a custom? I just really want to be able to get OTA updates and hopefully solve my Skype video issues...
Thanks in advance!

I see vache has a couple Full 3.2 Stock 501 roms on his thread here :
http://forum.xda-developers.com/showthread.php?t=1113878
i got a a500 and i assume you extract the update.zip and flash as per a500. Dont wanna put u wrong tho' so maybe ask moscow on his rom thread, he da man when it comes to the 501
Okay - I'm going to try and flash that update.zip and see what happens. My biggest concern is the lack of Skype video - I can only assume it has to do with the ROM flashed, and nothing else, because other people claim they are able to use Skype video.

[Q] Help With JB Energy™ Rom

Just recently flashed a friend's phone with Energy Rom. The rom looks amazing and is very well designed. There are just a few issues that he is having and I have not seen anyone else experience these problems in the tread. (Too few posts to post there)
Her camera is not working and I guess her Hotspot gave her a "timed out" message. . . . If anyone else has experienced this, please let me know if you were able to resolve this and how.
Thanks!

Are you on the 4.1.2 update? If so you will need to flash back down to 4.1.1 kernel because the new kernel is not compatible with the 4.1.1 camera

Energy ROM is based off of the the 4.1.1 build, the latest update has the XT907 at 4.1.2. So if her phone was previously on 4.1.2, then flashing this ROM could cause problems as the previous poster mentioned due to the new kernel. Not sure if the developer will update his ROM any time soon (which I loved by the way, and keep checking his thread for any updates),
also, Energy ROM can only be installed via SS right now, and given that the bootloader has been unlocked, I believe that all ROMs will be flashable via TWRP/CWM going forward - thus making SS obsolete for the XT907.
Here's what I suggest though:
unlock bootloader
install TWRP recovery
try out the DeadRage ROM, which is based on the 4.1.2 build: http://www.droidrzr.com/index.php/topic/17778-romretail-deadrage-v12a-05092013-412-base/
if you really want to stick with Energy ROM with working camera, then you still can:
flash back to stock (4.1.1)
root
install SS
unlock bootloader
install TWRP
install Energy ROM on Slot 1
backup Energy ROM via SS
move Energy ROM to stock slot via SS
backup Energy ROM via TWRP (basically making a nandroid, and this can be installed going forward as a backup)
uninstall SS
Thanks!

Kernel?
Any clue of where I can find just the kernel I need to download and flash?
Sorry for coming across as a newbie, but I am used to other phones that have a bit larger of a community. Thanks again.

no worries - we all were newbies at some point in time.
I have not seen a thread dedicated to the stock 4.1.1 kernel, but I did find this:
http://forum.xda-developers.com/showthread.php?t=2017200
my advice at this point is to backup your apps/data via TiBu (and then copy that backup folder to your mnt/external1 directory).
so that way, after you pick your ROM, you can re-download your apps from the market (I always recommend doing this as opposed to letting TiBu restore them), then you can use TiBu to restore data ONLY from your apps. I do NOT recommend restore system data though when switching ROMs (however, I do restore WiFi settings and bluetooth pairings).
hope this helps.
All worked out great! I appreciate the help. I ended going with Energy 4.1.1 I have that stupid grateful dead image stuck on first power up due to rage. -Annoying!!
