[Q] Flash rom on Chinese Iconia A500

Hello,
I bought an Iconia A500 in China and I have a few problems (device not recognised on market.android.com and limited chinese version of Android market app).
I think that the solution would be to flash a new rom to get rid of the chinese system.
Which rom do you advice me to flash (just need something easy to do and stable).
Thanks for your help !

Ok, as nobody answers, I list what I've been trying :
After having rooted my A500 and installed Acer Recovery, I tried to install the USA OTA rom from Acer recovery but it did not work (I get the exclamation mark + green bee screen when I reboot).
I installed the morelocale2 app which is supposed to fix some localisation problems (language, etc). It kinds of works, but does not fix my android market issue.
I found some OTA update stock ROM (can't post the link, google : "Acer Iconia A500 Original and OTA Update Stock ROM Package List") but I don't know which one corresponds to my A500 (my build number is : xxx1.135.02xxx).
I don't know what to do now ?
CAN ANYBODY HELP ME ????

the update you downloaded that failed to install: did you decrypt it first? As far as the version number goes, that is irrelevant if you are talking about a full rom. Another alternative its to use a custom rom, such as the excellent lightspeed or taboonay roms, both found in the development section.if this doesn't clear everything up for you, just let me know

DroniX

Hi
im new to android ..
i own a ideos u8150.........and i have rooted it with z4 root
I also have managed to install clock world mod 3.0.2.4 i flashed it through pc (works perfectly)
now i want to change my stock rom ..i' heard ideos HD and droniX are good roms
i'd like to install droniX 0.6 raw ginger ..
but can anyone help me in flashing the rom i need a guide..
also how can i make full backups so i can revert to my stock rom anytime i want..
Does switching to custom roms affect baseband of my mobile ..
because of a picture i saw in a blog that says "baseband version :unknown" in mobile settings .
i have been a apple user and to jailbreak you need to preserve your basebands so is there anything like that in android
i have also read that after flashing dorinX .6 many see a black screen ..how can i prevent that..
i've also installed rom mangaer free version from market but its useless because everytime press any option it tells me to install colckworld mod and when i press install a list of phones comes up but u8150 is not in the list only 7 options.......
Thankyou

You won't get much love here as this is in the wrong forum, but here is a link to my rom:

You dont need to use my rom, it just has flashing instructions in the first post.
*Good luck with ginger, it is still not stable, so maybe stick with 0.5.4.
*Baseband is not changed by flashing roms in CWM, only by official huawei update software, find a copy of yours before flashing if you can.
*CWM has the option to make a NAND backup under backup and restore.
*Dronix is good, Leandroidmod is ok, Ideos HD seems to be deprecated as I had bugs which I reported and have not been fixed so I switched roms. Has not had an update in months.
Here is the wiki page for u8150, have fun:

[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
olivier

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

Help with installing CM9 on A200

Hello,
My GF just got herself an A200, but she experiences it is a bit on the slow side at times, so I wanted to install a custom rom on it.
Been doing that before on a few phones and my Galaxy Tab 10.1, but after digging in this forum and over at the Acer Tablet Forum I am still not sure if it is all that easy on this tablet.
Sooooo, I was wondering if the coming steps are what it takes to install what I had in mind and if that actually works.
The SimpleRoot topic on the Acer Tablet Forum gave me enough info (assuming it works) on how to get root and install CWM.
Now I wanted to flash (after making a Nandroid back up) the latest CM9 Rom with Obsidian's CM9-Onyx-OC-1.5ghz-v1 kernel.
I have no doubt that somewhere, on either this forum, or on the Acer Tablet Forum there is a guide on how to flash these, but after searching for hours, I still am not sure if I know it correct...
Can I just flash the latest CM9 rom, followed by the kernel, in CWM, from an external sd-card, or are there any steps I need to do before/after that?
This is how it seems to be done considering how it went on my galaxy tab, but I am not confident that it is that simple on the A200..
Thanks in advance!

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.
