I decided to root my i9020a cuz I wanted to try the goodies. So I installed the CM7, but didn't quite like it, so then I decided to install this rom that is a kinda inbetween the stock and the CM7, but all of a sudden it died on me after a reboot I did after several days using the rom without problems.
So, I decided to install the stock rom from here and so I did. Ever since my phone doesn't connect to the 3G network and I checked with my carrier and I didn't go over my limit or anything, so I'm thinking maybe I screwed up the baseband or something.
So I tried this, but that didn't work. Tried directly doing to 2.3.4 and also first to 2.3.3. and then updating, still no 3G.
Currently my baseband reads: NO DGSXXKB3, but I remember that when I got my phone it used to read: I9020AUCKD1
How can I get back to I9020AUCKD1? Any ideas? Am I way off and it's not the baseband? Help? I'm really desperate now after hours of lurking around google and here
For 3G I need HSDPA 850 / 1900. I'm aware the phone supports 2100, but my country doesn't.
Thanks in advance

Dude - you are a life saver!!
I don't know why, but this morning I woke up with no cell reception - no phone calls, no data - on a day my son was sick and I had to call his school - I have no landline! lol. All it would say is "Rogers" in the available networks.
Got it figured out though, wiped the thing, stock 2.3.4 image, then with the settings you had above, bam, worked like a charm. Back on koodo.
Phew! Thanks again
I've completely lost 3G ability on my NS, and I'm not sure what happened.
Here's my order of tweaks:
CM7 nightly (with 3G)
MIUI (with 3G)
ICS rom from SDK (no more 3G!)
ICS from kwiboo (no 3G)
ICS from koush (no 3G)
CM7 stable (no 3G)
I guess sometime during my playtime with the ICS from SDK build, something messed something up and subsequently I cannot get 3G anymore, regardless of ROM.
I'm not sure where even to begin troubleshooting.
- Yes, "use only 2G networks" is unchecked
- My APN should be correct, as they are the ones that loaded automatically from the ROMs. That has always worked before
Anyone have any ideas? I'm desperate for help. I haven't had 3G for what feels like a month!
Here http://forum.xda-developers.com/showthread.php?p=19424857 in this post there is a link to the radios try flashing one of those to see if that fixes things. If not try flashing a stock unrooted rom and start over

You know what? A new radio worked! I don't know why I didn't think of it before. Seems so easy in hindsight.
This brings up another interesting thing. Seems like a lot of the radios that used to give me 3g don't give it to me anymore, including the most popular ones people are using. That's weird...
edit: Actually, no radio issues anymore. My old radio gets 3g again, as well as others. I just needed to rotate the radio versions a few times and reboot a few more times and it fixed itself. Totally weird, but no more problems!
I had the same issue on AT&T 2 nights ago. It turned out that it was an AT&T network issue which was confirmed by tech. support.
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)

http://http://goo-inside.me/roms/teameos/gapps/EOS_GApps_ics_4.0.3_v10.5.zip
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....

About 3 weeks ago after installing the update of liquidsmooth 4.4.4 i randomly started dropping to 3g service in places that i normally had full 4g available. It has slowly gotten worse to where if im not on wifi, than the phone is pretty much useless. i normally have full coverage everywhere. so i originally thought that maybe something had gotten messed up on the update, so i did a clean install of liquidsmooth 4.4, and blackbird kernal and same thing still occurred. also tried carbon rom and slimrom, and no luck. so for the fun of it, i went ahead and reflashed the phone back to stock from backups and rerooted it, updated the modems and reinstalled liquidsmooth w/ blackbird kernal, and same thing. i have went through all the mobile networks settings and tried everything and nothing seems to help, idk if that update screwed something up or if its an issue that others have been experiencing as well, or if im just screwed and my phone phone is dying.... any help is appreciated thanks

I'm currently running OmniToad, and ran CM 11M8 for a short while. On T-Mobile at least, with the custom ROMs it's normal to see H+ only when data is being transferred; it will drop back to 3G otherwise. When I ran the stock ROM on the Relay, it would always say "4G" regardless of whether it was in UMTS (3G) or HSPA+ mode. Apps like SignalCheck or CellMapper will tell you which mode it is really in.
On the other hand, if data transmission is only going through as 3G, it could be a phone issue or a tower issue. Is LTE available in your area, or are they just getting it set up? I know when T-Mobile was upgrading the Chicago area to provide LTE, there were a few glitches here and there.
It was stupid for T-Mobile to brand HSPA+ as "4G" but that's a different rant.

yea LTE has been in this area for quite a while now, i had it with my S4 and it worked perfectly, i never had a problem with the service on the relay either up untill a few weeks ago the internet speed and and data coverage was great, not quite as fast as the LTE on my S4 but it was still more than adequate, i used to use the hotspot and stream netflix on my laptop. now i can usually get a text to send but calls usually fail and if i try and use the internet its impossible. it almost seems like its doing the exact opposite of what it should be doing, as soon as i try and use anything (not while connected to wifi) than it drops coverage to 3g/edge/ or to nothing at all. Im leaning towards the hardware failing side, but i figured i might as well give it a shot and post it and see if maybe i wasnt alone. thank you for your reply.
small note of background on me: first time posting ever in this forum but have been using the tools and roms from it for a long time, so im not a complete noob, but i definitely still have a lot to learn.
I was asked to also post this fix that I came up with in the general forum from the CleanROM thead, as it should help people having the same issue. The issue isn't actually related to that ROM but a broader M8 issue that I was unaware of and thought was specific to the ROM. It's been confirmed with multiple users having the issue that the fix below does indeed fix the random data issues that require a reboot/airplane mode toggle to resolve.
A fix for the 4G --> 3G, WiFi --> 4G, WiFi --> 3G, and 1X/3G --> 4G handoff issues that some people may be having is outlined below...
In a nutshell, we just need to change EVDO Rev A to "Enabled" instead of the 3rd "eHRPD" option in EPST.
Dial ##778 --> Edit Mode --> 000000 --> Modem Settings --> Rev A --> Enable --> Upper Right Corner Menu --> Commit Changes
Might cause a reset data connection with the transition due to a possible new IP or hamper simultaneous voice and data over 3G (which is possible), but it will allow the phone to establish a data connection on its own again and not get stuck on eHRPD 's random buggyness. Should transition back to 4G eventually as well
eHRPD basically for allows switching between LTE and EVDO systems seamlessly (no reset data connection from 4G --> 3G and back, slightly faster speeds, same IP, depends on tower...)
Changing this setting basically tells the modem in your phone to act more like a 3G phone when requesting 3G data access. Bypasses the hybrid-ness and just forces you on the legacy EVDO Rev A. network.
If the phone signal (4G is weak) at the time of the eHRPD transition, it can mess up. This change tells it to not bother with that and when the 4G signal isn't available just revert completely to 3G to register and not wait up for transition info. Makes it more cut and dry, and to be honest it does not really impact things. When the phone detects a 4G solid signal again it will switch back on all its own.
Same issue happened on the HTC Thunderbolt when Verizon was messing with things during initial 4G deployment. Only recent changes are the whole VoLTE ramp up, and that could be the cause of this recent crazyness.
To revert this change:
Dial ##778 --> Edit Mode --> 000000 --> Modem Settings --> Rev A --> eHRPD --> Upper Right Corner Menu --> Commit Changes
Thank you for sharing this! Very good find and positive feedback has been showing in response. Worth a try for everyone having these symptoms.

Isn't Android Revolution HD is in the Generic HTC One M8 section?
Sadly, this only works with VZW based ROMs. Anything with parts taken from other bases, or a GPE ROM it may not work and the code for EPST might be different/EPST might not work and/or the option may not be there.
That code doesn't do anything on the Viper rom

Sounds like you guys need to flash CleanROM...
After making a Nandroid back up of your current system then do the edit and restore Nandroid if you want :angel:
But to answer the OP, yes. GSM ROMS will not have this option unless the Dev adds it in. Otherwise its a CDMA only function (I believe).

It works on my viperone 1.8, are you on the newer versions that you do not have the new verizon firmware for yet ?
This is great, I come from an HTC One S but also switched between that and a Galaxy Nexus so I could tell a difference in the way my signal acted and we have had signal issues with the HTC One S for quite some time now and it all seemed to stem from when we finally obtained s-off, seemed our One S was never the same, may have been placebo but I was worried it was happening all over again with our blessed M8 lol. The One S was not Verizon and may not be the same issue. I just tried this and it already seems better.Thanks very much. They still have not found a fix for the HTC One S

I'm holding 2 M8's next to each other, one with the fix and one without, I am showing smooth 4g and she is showing a confused 3g lol.

If you go back to 1.8 then it will probably work for you, 1.8 was the last verizon that worked correctly for your verizon firmware. I was on the 2.3 but had too many wifi issues so I went back to 1.8, which is less wifi issues now with this fix I seem to not have any wifi issues so far so think its working for me. I"am not going to update viperone until the new verizon firmware is out in a zip to flash in recovery, because the wifi issues are not worth it to update now.
Any more successful difference's people have since doing this?
I was listening to a radio show streaming app today on Wi-Fi and the app kept stopping. every 10 minutes or so after trying this fix. It was the first time I listened to this app with this phone but listen to this app all the time with my other phones and never have this issue. It was consistently dropping Wi-Fi and 4g wasn't picking it up. I am running CleanRom with Harmon Kardon. I tried disabling Harmon Kardon to see if that may have been the issue since I am not accustomed to using it yet and it seemed to work better without it but still dropping signal. The signal icons seemed uneffected. I guess I am going to remove Harmon Kardon see if that makes a difference before I revert back from this fix.
I did this and my phone now reverts back to LTE and doesn't get stuck on 3G like it had been doing since day 1. I was getting tired of cycling into and out of airplane mode. Thanks for this advice/fix!
Is this the bug I experience where I have 4G signal, but am "offline"?
If so, that has been driving me nuts. I am on the stock ROM, S-OFF Rooted. Is this present with the off the shelf version?
Reporting back after 3 separate complete wipe/reflash/restores on my M8. Here is my status as of now:
Tuesday: Tried flashing stock recovery and did factory reset. (didn't fix the handoff issue)
Wednesday: Tried flashing RUU then returning back to CleanRom 1.4 (didn't fix the handoff issue)
Thursday: tried the EHRPD fix listed below. So far today NO handoff issues! I don't want to jump the gun, but this appears to have done the trick. I have gone from 1x to 3G to 4G with no issues so far.

If anyone is using the Verizon M8 with a GSM sim and can't access the USSD code ##778# then go into settings -> mobile data -> preferred network -> LTE/CDMA and try running the code again in the dialer. Dont forget to change the preferred network back to Global after applying the fix by the OP.
This has worked great for me. Thanks for posting. Was incredibly frustrating to have to fight with the phone every morning on my way to work to get it to connect to 4g. I had to toggle airplane mode, switch preferred networks and even reboot or some times do all of the above - lol. Thanks again.
Apparently this is a known issue and per Verizon, they're working with HTC to fix it. But I've also read that the problem could be cause by running xposed modules which seemed to be the case with me. I'm s-off running stock and was fine until I installed xposed.

This fix does not impact Wi-Fi directly, just eHRPD for mobile data transitions. Sounds like the app is the problem. Have the same ROM with Harmon Larson installed - no issues.

Yup. Seems to be impacting certain phones regardless of ROM. I'd give it a shot and see if it helps. If not just change it back.
Big thanks to the OP. I've been dealing with the the eHRPD limbo since I got my phone in April. I live in a low 4g area and was experiencing text and mms problems big time. It was always happening when it was bouncing for 3g and 4g. When I would check the network details it would say eHRPD. I would constantly toggle airplane mode off and on and change network preferences to get it to work. Really annoying. Well I tried this last night and the signal is staying in 4g almost all the time and I have experienced no problems with messaging. I am running Viper 1.8 and had to kind of guess to find the edit button after entering the numbers in the dialer, for some reason the Edit button did not show up but it was there when tapped on it. After that it was easy. Thanks again for the help. I wish Verizon was as good.
