What ROM should I use? (Can I have GSM or not?) - Xoom Q&A, Help & Troubleshooting

I have the Xoom MZ605. So it's an Everest. Right? However...
I've seen descriptions such as:
MZ601 = Xoom 3G + Wifi Europe model and it's called "Everest"
MZ600 = Xoom 3G + Wifi Verizon US model called "Stingray"
etc.
And I've seen people say that Wingray and Stingray will work on the MZ605, except I will have no 3G.
Well, question #1:
My unit does have a SIM card slot. I was even required to insert one before I could use the unit for the first time. After that, it was not required anymore. But the official firmware (upgraded OTA once to 4.0.4 by Motorola) never had any phone application, neither can I use the SIM card to have wireless internet. So I've been using WiFi only for years. Can I have mobile phone and internet connectivity with a CM firmware? Does this unit even have a GSM radio?
question #2:
There are too many CM firmwares and I am confused. Which ones would suit me? I've read somewhere that 4.4.4 is too slow and unstable, same as CM 11, and that CM 10 is recommended instead. But that page is 2 years old and things may have changed. Which ones do not cause any problem? I really need all the hardware features except HDMI.
TIA

No one is here now. I've been looking for a light weight firmware to use but these tablets are to old now

[Q] question about sd card slot and 3g (not 4g)

hello all
about sd card slot, as i see in forum, it's not usable yet. why? that is a lack of hardware and will be usable after 4g upgrade? or it's just a software issue and can be used with hacking android?
and another question, the 4g will be available after hardware upgrade. how about 3g? is hardware needed for 3g , 2g (gprs) installed on device? i mean is it possible to use 3g with hacking software or it's lack of hardware
thanks in advance

4G is a pure hardware issue. Hardware changes need to be made, that is why the 4G upgrade, when it happens, will require the Xoom's to be brought into service centers. Nothing you do to the software can add 4G.
As for 3G, it is also a hardware question. If you bought a 3G Xoom, you have the proper hardware for 3G...if you bought a WiFi Xoom, you do not. No hacking possible or required.
If you want 3G and bought a WiFi Xoom there is a very easy fix however. Put the WiFi version on Ebay or give it to someone, and go buy a 3G model.
Quick and easy, all fixes should be like that.

Then I would suggest checking with your carrier.
Im from iran. Here we have not 3g carrier yet. Both operators here are 2g network. The carrier i use, the network is EDGE, cannot i use mysim card for gprs internet? Just like gprs in htc.
And also in setting, mobile network, i see an activation. What is that? I didnt activated yet. Is it activation for verizon carrier just in us?
For using other carrier device should be unlocked like God dang iphone or ... ?
stock browser
Also another question. I installed a few browsers but the best browser is the stock. The only problem with it is typing, for example just now, i'm wroting this o xoom but writting speed on stock browser is very very slow
What is the problem? Is there any solution? Or any better browser?
also i forgot to say that my rom is stock rom and not rooted yet

Typing lag is a known issue on the Xoom. Are you running 3.0.1 or 3.1? Most people say it improves with 3.1. YOu can also try rooting and installing one of the custom kernels with overclocking, either Tiamat or Launchpad. The Tiamat kernel cleared it up for me, even with moderate overclocking (1200 on mine, usually).
Lots of guides here to help you upgrade, root or install either kernel.

I can't say for sure, as I have a WiFI only model. Likely the Activation option is relevant for Verizon only, but put the SIM card in and choose the option, see what happens. I would assume that if your SIM card is legit, then it should work on the Xoom, but this is unknown territory for me.
Anyone using a 3G Xoom with gprs?
i use my sim card with my htc hd2 (android), i'm using gprs a lot on it
and how about sd card slot, the reason it doesnt work is lack of hardware or can be done with software hacking?

The lack of an SD card is a software issue. Use the Tiamat or Launchpad custom kernels to enable it.

[Q] (help) motorola xoom 3g verizon ..updated to ics wifi only os

Hi guys I need help or info about this Ive always wanted Motorola Xoom wifi only but I received Verizon one with 3g not upgraded to lte . I rooted it and installed ics for the wifi only system from Google or android website its stock ..
And works actually very well no 3g ..nothing about service I don't mind since I'm not with Verizon and not planning to go with them I just need wifi but my question is ...is it right I mean everything works good only the battery It seems like honeycomb stock verizon build battery stays longer is it because of wifi only ice version ..or something I'm not sure if somebody can help me with info
Hmmm ... me too. I have a Xoom tablet arriving this week, and it was listed as "MZ600 Xoom, LTE ready, Verizon". Which rom version should I install? I do not plan to activate it with Verizon, as I already have a dinc running CM7 nightly build 258, and waiting for ics. I would just like to run ics on the Xoom. If I don't activate the Xoom, which rom should I use, or CAN I use??
If both of you are not planning to activate with Verizon, using a Wifi only ICS ROM won't be a bad idea. I too have installed this to a friend of mine and he hasn't experienced any issues. You will not be missing out of any features because the only main difference is the 3g / LTE radio.
So anyone has seen the stock ICS for the xoom 3G version?
AFAIK wifi only is the only model to get an official update. Running the wingray build on cdma or lte is just fine.

It's complicated!

Hi fellow Xoom owners.
I'm having this issue with my 3G Xoom that I can't just get past.
As soon as FedEx handed me my internet-ordered tablet, I started looking into rooting methods and all.
Strangely, even though I live in Saudi Arabia, I received it with the US firmware, kernel or whatever it's actually called (MZ600 - XOOM WITH WI-FI + VERIZON 3G Build HRI66) which I didn't know at the time it was Verizon's but was wondering why 3G didn't work.
Anyway, I followed a rooting tutorial without paying attention to the build which got my Xoom stuck into the Moto logo thing.
Following tutorials into how to restore it, I downloaded the right build for Saudi Arabia (MZ601 - XOOM WITH WI-FI + UMTS Build H.6.1-38-9 for Retail Other International) which worked like a charm and with 3G!
Since, at that point I was already out of warranty, I flashed a Tiamat ROM and worked great but without 3G (bummer!).
Going through ROM trials, I'm now on Team EOS Verizon 4G ICS ROM but, as you've already guessed, no 3G for me (duh!).
I noticed that Team EOS are also working on a MZ601 ROM which should have worked to my favor of regaining 3G back but is somwhy isn't.
Bottom line of the story, I want to regain my 3G back while staying on an ICS ROM, preferably Team EOS's .
It's way better than the Honeycomb it came with and I'm not ready to lose all my game save files again!
Please help me.
The Link you provided in you post (Team EOS Verizon 4G ICS ROM)- That Build is not for your Device, as you device is not MZ602 with 4G LTE. Seeing that you received a US MZ600 Xoom that is actually CDMA and not GSM, it is suprising that the MZ601 UMTS worked for you. But since you say that it worked:
Try this one Team EOS ICS, EU 3G Xoom (umts_everest / MZ601)

As Always, If This Was Helpful - Hit The Thanks Button!
I've already tried that ROM and for some reason it did't work.
Though on earlier versions, it used to give me a certain error which goes something like "phone.android.'something' stopped working" but now it doesn't.
As for the build I received it with, I haven'y the slightest idea how that happened!
I even took a picture of of my tablet before rooting in case anything went wrong... here.
Check this thread, you can try out Umts Everest - Euro & also Stingray 3G, as you are having CDMA xoom

Seems promising but gives me the "502 Bad Gateway" BS.
I'll try a bit later or will look for other sources.
EDIT: BTW, since I'm already on ICS, I don't need to factory reset, right?
yea there seems to be an issue with the download links.
its better to do a clean install, you can always backup your apps & data.
Since you brought it, how can I make a backup of my data?
By data I mean game saves 'cuz that's what I can't afford to lose {: s
I wanted to install CM9 on my Galaxy SII but stopped at the same data backup problem.
And, isn't there any tool to use on my PC to backup apps & data and manage my device ROMs... etc?
Titanium backup is one of the best apps to backup data and apps in my experience. You can find it on the play store. Also im not sure if you can buy the pro key for it but it makes reinstalling everything a breeze. Can you still connect to wifi?

@fredrick
RedXXII already gave the answer which i was gonna say. titanium backup is the best, you can backup & restore app + data easily. you just need a rooted device to use titanium backup.
So guys, let me get this straight:
You're saying that an MZ600 Xoom will work on a 900/1800 3g network just by flashing it with a european rom? I thought this was impossible
thread starter himself said that he flashed a 3G rom, which worked for him
I downloaded the right build for Saudi Arabia (MZ601 - XOOM WITH WI-FI + UMTS Build H.6.1-38-9 for Retail Other International) which worked like a charm and with 3G!

that's y its suggested to him to flash euro 3G rom
I have absolutely no idea how this happened.
I bought it from an Arabic online store for use in my country but received with a different ROM.
After restoring my tablet from the Moto logo error, I restored it to the official international firmware and it started working AND with Arabic support!
Maybe seller ordered the wrong software on the right hardware???

Agreed. The electronics involved in GSM and CDMA is definitely different. I think that is why his data never worked in the first place
OK.
I finally found working links for the codename android ROM v1.6.0 and tried the stingray 3G and the umts and none worked.
Any idea on what could be done at this point?
I re-checked the data bearers of both International and European firmwares and they are exactly the same.
Couldn't there be something like a missing driver or so that would make my Xoom recognize the carrier?
Or alternatively, isn't there a way to unlock it to any carrier supporting the same data bearers?
This is puzzling me for some time now. I have an MZ600 (Verizon 3G without the 4g upgrade) but I live in Europe. I know that MZ600 has Qualcomm MDM6600 which supports both cdma and umts. So I thought that using it in Europe would be as easy as switching Team Eos rom from "stingray_cdma / MZ600" to "umts_everest/MZ601" . I had the idea that this would change the baseband and I will manage to register on a 3g (european) network. Sadly, this isn't true and I'm still puzzled whether this is even possible or I haven't found the right way yet.
So to sum things up:
Is Qualcomm MDM6600 capable for both cdma & umts?
Is so, does anyone know someone that managed to get the MZ600 to register on a umts 3g network ?(you may see the signal of 3g but you cannot register)
If anyone can shed some light regarding this issue, it would be nice .
Check product specs for your original country and current place of use.
I believe they have totally different data bearers.
But, who am I to say?
I'm the one with a paradox over here!
so mr. Fredrick Sylar
what version of the xoom do you use...? the MZ600? or the MZ601?
well anyone ......?
have a look at this guys....

Xoom 3g vs Wifi which more worth?

Yes I have noticed the similar threads and I came across them but I want to get the specific answers from XOOM experts;
-I want to purchase a tablet for my GF and a lil usage from my end as well(gaming?).:laugh:
-Right now in the UAE I can have the 3G version for $249 (with the protective folio for free) and the Wifi only @ $221 (Uk version cause it says it has the UK plug? standards here are all UK based I believe)
-I know the basics now(you can tell from my sig) about android, de-brand, use different firmwares for different region models of the same device (eg.Galaxy Nexus takju vs yakju).
1. Which is really better to get, the 3G variant(yes can tether thru any android phone but is only having 4.0.4) or wifi(which I have read has the the Jelly Bean 4.1.1?
1.5 How is that team EOS or CM10 as a daily driver for the xoom? can it be used for both wifi and 3g version?
2. How does this stand to the nexus 7 as of now? I know the device is 1 1/2yr old now Hint; my GF does not like squinting LOL, maybe she'll be using a tab for facebook epecially poker, e-mails, pictures, and videos (1080p is supported?)
Hope the experts could chime in to this dilemma I am having..
PS..not considering iPAD, no way!
BUMP
for an answer from the experts
Get the 3g, you can load any rom on the xoom be it wifi or 3g rom, all 3g xoom is quad band 850/900/1800/1900,My understanding is all internal parts are the same, only radio software, be it umts, cdma, gsm.. my xoom is a cdma 3g, when motorola have any new ota updates for wifi only i load my 604 wifi backup and test, when verizon decide to send their ota i load my 602 backup..

Custom ROMs -> Bad or no LTE connection (SK Telecom, Korea)

Hi All,
Just recently bought an N5, and really loving it. On stock ROM, I have no problem with LTE connectivity, wifi etc... but whenever I install a custom ROM, I lose that connectivity. I 'force' the LTE APN from settings, and I've also tried creating a new APN with the correct settings for my region, however I never get the LTE connection. The icon at the top just stays at the "H" or "H+", which if my memory serves me correct refers to HSDPA or something like that (aka 3g). I use an unlimited data plan, so this really sucks.
Anyone know a workaround where I can use custom ROMS and use them here in Korea? (SKT carrier)
Thanks,
J
p.s. any suggestions would be welcome, as I'm aware that this sort of problems exist for a lot of N5 owners after searching the web. However I could not find any fixes.
Problem solved, seems like certain ROMs are incompatible? Maybe something to do with the radio frequency / kernel etc...
Not sure why, but installing Xenon HD ROM has solved all my problems !
You can use the /etc/apns-conf.xml from any SK device, like a Korean s4 or the one from the stock n5 rom. Just replace the one in which ever rom you're using.
