I have an a501, would an a500 ROM benefit me? (battery wise) - Acer Iconia A500

I got a great deal on an a501 and would NOT be using 3g.
Since most ROMs are for a500s, and wouldnt have any 3g capability, would using one of those extend my battery life since there would be no polling for any 3g signal and it would be entirely disabled?
Again, I have no interest in using 3G so the fact that the a500 Roms dont have 3g capability does not bother me at all.
Thanks!

I am pretty sure that if you install a ROM meant for the A500, that 3G will be disabled, but you also have to disable the cell standby (even A500 users have to do this) to disable it, all you have to do is to add ro.carrier=wifi-only on to /system/build.prop. you must have a custom kernel installed found here. also, I am not sure if you need a custom ROM but if you are installing a custom kernel, you might as well go the extra mile and install a ROM as well. (P.S. the custom kernel i linked you to also lets you overclock to 1.64Ghz)
I have used one on my Iconia and have never gone back. there are many ROMs and I can not tell you which one is best for you, however, i can tell you that I like this one. Another popular one is this one. try them out, but of course make use of the backup feature in CWM just in case happy flashing!

You shouldn't need to edit the build.prop if you flash an A500 rom as the build.prop would already be for wifi only.
You will definately loose 3G functionality a the A500 roms don't support it.
Unless you are using 3G all the time this shouldn't affect battery life too much.... Depends on other factors, do you have apps that are regularly accessing 3G behind the scenes...
If you have a wifi tab then the best idea is to turn wifi off to improve battery, you could try turning 3G off on your A501 and see if that helps... If, like me you have wifi on, pretty much always, then it probably won't do much...

Thanks for the replies

ROTO,MODACO,ETC....which one you prefer?
Trying to find stabil firmware for my brand new australian tab, can not make my mind yet...
Still looking stabil one and I don't want to upgrade my firmware every weeks for the new firmware add on.
Any advise??
Response for what it's worth
I'm not sure if I'm the one to advise you, but I have just flashed my Optus unlocked tab with Roto JMI v1. Being a noob, I must say that the instructions given worked a treat and the flash went perfectly.
Although it is early days, iot seems pretty good to me with an improvement in wifi which was fairly random previously, but I still have some testing to do on the GPS. Others on the developers forum seem to have no problem though.

For me I like the Modaco Roms and Kernal. His roms are great on my other android stuff as well.

Wifi seems to be solved for me with JMIv1.0. No dropouts. For the GPS you might try the FasterFix from this topic. That works great for me.
I prefer the Roto-roms above those of Modaco. The Roto's are most a kind of 'out of the box' roms, and can be used without doing some really tweaking like the Modaco's. But just try them both and compare the difference, feels and looks.
I have tried both and they are great compared to stock rom. Below is my conclusion(solely on my experince of flashing roms for 1 month now.
Roto
- easy to flash
- good speed
- clean wipe with minimal add ons so we are free to add what we want
Modoco
- flash can be difficult and need to poke around and do some mistakes first
- blazing speed, getting constant 1800+ in quadrant
- got everything working good in my asian gsm tab
- auto connect/disconnect between wifi and data which is good
- love the reboot option on power button

Thanks for the advice.
I have tried the GPS fix, but no luck, and I think the Wifi issue is much more to do with my router than Roto's great work. I think I'll try JMEv4 as I jumped straight to JMI.
I appreciate your help.

Well, I didn't go back to JME, I tried JMI v2 which has just been released by Rotohammer.
The short answer. for me, is that everything went smooth again, and is working well except for the GPS which just refuses to work.

Hi, can you tell howto do the EXT4 kernel step of Modoco ROM? I failed to flash the kernel all the way.
My current ROM is Roto JMI. Should I flash other ROM first?
Thanks.
MCR for me. I live the kitchen utility Paul provides. Plus, its a very stable rom.

When i did the ext4 conversion i had to be on jme to flash the modaco kernel. It would not work for me on jmi. Hope that helps

What happens if you flash a non 4g rom onto a 4g xoom?

I have a 4g xoom that I bought used and use only on wifi. Does flashing a rom that doesn't support 4g simply disable 3/4g? Or will it not work at all? Are xoom roms even worth flashing or is a kernel a big enough speed increase?

Flashing the Odachi kernel will give you overclocking and lots of added functions while preserving your 3G/4G. It's good to keep it even if you don't plan to use it.

Would I not be able to flash back to stock to get it back?
I actually moved back to an OS that deliberately does NOT have 3G/4G. I don't have the service and just use WiFi but even in Zirplane mode, after the upgrade, my battery life went from days to hours.

[Q] Why root?

Hey guys,
I just got an Iconia for Christmas and love it to death. Seems like the perfect tablet for me.
I see a lot of stuff on this forum about rooting however and I'm curious what the practical benafits to rooting are. I origionally had planned to route the iconia because I heard it didn't support netflix but the netflix app seems to work fine on my device so I'm happy there.
There were a lot of things that made me want to route my phone (Samsung Epic) such as the desire to tether other devices to it and get rid of all the Samsung, pre-istalled BS and Touch Wiz which made the phone run slowly. Those considerations don't exist here as Honey Comb seems to be plenty fast and there doesn't appear to be many BS additions from Acer.
So, with all that in mind, what exactly does one gain practically by rooting the Iconia?
I rooted my a500 so I could connect to ad-hoc networks and use ntfs drives.

It is a very personal question in the sense that there is no one, single reason why people root. I for example rooted because I needed ad-hoc wifi, otherwise I could have well survived without rooting. Once I did root my tablet I did of course install CWM so I can take a full backup of the whole thing -- better safe than sorry, as they say -- and tried a few different ROMs too, though I then went back to stock as it was the least buggy.
Just ask yourself: is there anything I need root for?
I think I root for a few different reasons.
ClockworkMod for nandroid backup and other things.
Titanium backup for app/data backup and easy bloat remove/restore.
AdFree
overclocking and other performance adjustments
Cifs/Samba support - I have 3 androids with share links on my PC desktop for drag-n-drop file copying without wires.
Root explorer of course.
Drive mount seems to need it.
Oh and theming - I like to theme and make small code changes.
Essentially, if you need to ask that question, you don't need to root your device....
You'll know when you need to...

What does that have to do with the fact that I found all the custom ROMs I tried buggy?
Thanks for the advice everyone.
I was all set to root because I heard that Netflix wasn't functioning on the Iconia and rooting was easy.
Now I find that Netflix works fine and apparently I shouldn't have let my tablet update when I first turned it on.
Guess I'll leave my Iconia alone for now.

One word really - titanium - there is just no better way to make a full backup.
But having said that - with all the rumors of ICS withing maybe weeks - rooting may not be such a good idea right now ... most OTA updates do tend to have issues with rooted devices.

why root
i root for:
cwm recovery image
optimized roms
titanium backup (altho my stuff is mostly cloud so this is just a bonus)
while i understand why people say only root if you have to, if you've made your way here i'd suggest you do it anyways if only for the clockworkmod recovery while more or less makes your system unbrickable. when you start looking at custom icon packs, gps, wifi and lag fixes, optimized filesystems etc. it gets a lot more appealing.
thanks to those that tirelessly work out the kinks in the process for us.
Havent seen a reason yet to root my A500 as it does everything I want, possibly if I got a wildhair and wanted to install a custom rom. On the other hand I bought a Kindle Fire and I rooted it and had a custom rom installed withing a week, primarily to make it more like my Acer.

Unbrickable? I keep seeing threads of peopleeho havd just bricked their systems while trying to foot. It's the main reason why imhesitant to root.
I just got mine and always thought I would root it, but I don't see the point yet.
I rooted my Evo so that I can remove bloat, increase battery life, and most important wirelessly tether with my tablet.
The battery life on my tablet seems amazing, honeycomb seems fast and the bloat doesn't bother me as much.

Honeybar!!!
i rooted and installed thors rom, its awesome.
No real reason either, I just know from past experience every device is made more enjoyable with the right rom.
Plus with ics coming soon ill have to be able to backup my data to survive the upgrade.
I find out About Rooting (or unlocking) before I buy any device
#1 Freezing Apps (like Deleting, only safer -Titanium Backup)
#2 OverClocking to 1.5 Ghz and still being stable (up to 1.64)
#3 Under clock (216,245 mhz) (saving battery life)
#4 fun to be "ABLE" to tweak out something.
#5 Example : -a new trick to get better Wi-Fi or 3G Signal, or better GPS (you'll need ROOT to edit system data)
KNOWING that you can always get back to stock in under 5-7 min (if you have to bring in device)
Leaves you a better question.

Well bricking your tablet is normal when you try to foot it.
Sorry just made my laugh.
Maybe you should use auto correction.
Or maybe I should keep trying to foot it and see how many attempts I need to brick it.
I just got this tablet for Xmas, well the Packard bell one but from my understanding there the same. I still need to root mine. I've heard that you can connect a ps3 control if your rooted. Is this the only requirement?

3g or Wifi... Dont know...

Hey! I need some help
I want to buy a Xoom, but i dont know which to buy...
There are two versions in Germany:
- mz601 - Wifi + 3g for 405€
- mz604 - Wifi Only for 366€
You can see, the price difference is pretty small... I dont necessery need 3g, but maybe its a nice to have?!
Whats my problem now you think: I will definetly root the device and im going to spend a lot of time in development thread
I just saw, that there are not all roms compatible with the 3g model and more devs focus first on the Wifi only device...
Is it possible to flash wifi only roms also on wifi + 3g xoom and just disclaim for the 3g feature?
Then I would buy the mz 601.
If you tell me, that there are often problems with roms for the 3g model, i'd grab the 3g model.
I hope, you can understand what i mean and im looking forward to your responses!!
Greets from Germany
Yes, you can usually use wifi-only roms on a 3G device, just impacts 3G connectivity...usually wifi is no affected. Now US 3G sometimes has more trouble with custom roms as they have different gsm as opposed to US cdmi.
I'm assuming you can't tether to your phone. If not, I'd get one with 3g if you can afford the data plan
Can I use every Wlan Rom on an 3g Model (MZ601), but disclaim the 3g?!
Thanks for the replys...
@okantomi: What means "usually" in that case? Always or sometimes? What are the exceptions.
So that means, i could use the ICS Nightlys by Team EOS but without 3g integration?
Is that true for every Wlan- rom? I just want to be sure, that IF I flash a Wlan-Only-ROM on an 3g-device, it only effects the 3g to be missing.
I love flashing and being "up to date" softwarewise... I hope you can understand my concerns.
I just want to have 3g, if i want to use it in half year... Because a mobile or transportable device like this, is pretty cool with 3g. when you are on the way...
EDIT: I could tether... but i have a 3g limit of 500 mb... and basicly i am not allowed by contract to tether...
I could for a small amount, i only have to deal with the consequences

Yes that is correct. We will have a European 3G version at some stage as well.
Thx for reply, team eos...
So, there is no chance to brick the device, when i flash the nightly on an EU-3g-device, right?!
Nice to hear, that you will support 3g later

So, yes, since I have a wifi-only Xoom I have no direct experience with the 3G Xoom to draw on, but from what I have seen, unless the developer says otherwise, it is usually only 3G connectivity that is missing.

[Q] Does rom/kernel affect data speeds?

I installed liquidsmooth 4.0 some days earlier, i feel like i'm not getting data speeds as i used to get in stock ROM and kernel. Has the new ROM/kernel has affected it Or its just me.
If i tether connection from other phone using the same SIM i get higher data speeds about 1.5 times higher.

It might be an issue of the ROM not actually having a data connection when it says it does (data may be "broken" in the ROM, and only able to achieve a 3G connection while reporting 4G, and a 2G connection while reporting 3G, etc.).
This question should have been posted in the ROM development thread, and not in the Networking section. If it had been, the ROM developer, or other users, could either answer your question or post their experiences.

The data isn't broken but i don't get satisfactory data speeds. I mostly rely on 2g as my plan is 2g
definitely. Most custom kernels support different tcp/ip settings that you can mess around with. It can be time consuming, but so is almost anything on this site thats actually worth using. I tried this out last night, http://forum.xda-developers.com/and...mod-projct-mod-boost-nitro-x-edition-t2809443 I guess its a full package of tweaks that are pretty easy to use. I ended up uninstalling tho, and using the tweaks from my old ROM and putting them into the new one Im trying out. It did seem to work alright tho, but I didnt really give it enough time to really just say how much. good luck.
