I got a refurbished Xoom MZ601 WiFi + 3G from Amazon and it arrived today. The device looks brand-new and untouched, even the plastic was still on it and the screen. Great, I thought, until I powered it on and it was in German. I should have been tipped off by the EU power adapter in the box, although there was a US power cord as well.
Anyway, there was no option to change the language to English, fortunately I'm fluent in German and was able to update the OS to 4.0.4 and then the English (US) language option was available.
So here's the thing: the tablet works perfectly, except for one thing: there's a Verizon 4G LTE SIM in the device, but there does not seem to be any evidence of EvDO, even though that's what I thought I had purchased. I've tried using mobile data, but the only two networks the device sees are AT&T and T-Mobile. Removing the SIM card has no effect on the function of the device, but no 3G or 4G, for that matter.
So here are my questions:
- Is it possible that this is a U.S. version that was flashed to a different software, making the CDMA hardware invisible to the OS? I'm thinking this is a possibility, since AT&T and T-Mobile use micro-SIM cards for 4G, not mini-SIM cards, which is what is in there now.
- Is there some sort of diagnostic app that will scan and show me exactly what hardware IS in the device?
- Would some kind of serial number or baseband version information be able to tell me what it is?
- And finally, what are my options? If this isn't a Verizon device, that won't help me, as that's what I thought I was getting. If this can't be resolved by me, I'll have to send it back. I'm reluctant to do this until I'm absolutely sure there aren't any other options because the device is otherwise showroom new!
I'm new to the Android OS, so any help I can get is appreciated!
Well, post the details in the 'about' section of settings.

That will no longer be necessary. I found out that I have the European variant, so no 3G in this country.
I'm sending it back tomorrow and am looking for another one with Verizon 3G.

[I'd like to create a thread to collect information for all variants of the R530. I'll update this first post with additional information people give during discussion. Sorry it is here in the Verizon sub, but this is the closest model]
The SCH-R530 is a special flavor of the Samsung Galaxy S3 with sub-favors: (you should probably puke now)
SCH-R530U is a US Cellular variant
SCH-R530C is a Cricket variant
SCH-R530M is a MetroPCS variant
SCH-R530X is a Generic variant
I suspect these are all the same hardware, but just different ROMs. I would like to confirm this.
I would like to know and post the newest firmware versions for each. (at least the names, if not the ROM files themselves) I'd like to know if ROMs are compatible, if modem firmwares are compatible, if bootloaders are compatible. The small community of owners need to pull together as much as possible.
Model -- Hardware Version / Firmware Versions / Baseband
SCH-R530U --
SCH-R530C --
SCH-R530M --
SCH-R530X -- R530X.01 / JSS15J.R530XWWUBMK4 / R530XWWUBMK4
Please post if you can add to this information!
I'm working on my dad's SCH-R530X (Generic CDMA). It was on a regional CDMA provider that he was not happy with -- he paid $500 to them in January for the phone. Edit: Today, he's on PagePlus, but without data for some reason.
Concerns (that someone may be able to help me with):
Once you go to KK 4.4 you can not go back? Your bootloader is updated and will not boot 4.3?
I'm running 4.3, can I root -> replace recovery -> custom ROM ... without tripping the KNOX warranty void? I've read that saferoot will not trip KNOX?
This phone seems to have an odd Call Audio Quality problem. While listening during a phone call (on the R530), the other party's voice cuts out. Specifically, it cuts out when the other person isn't speaking in their mic close enough or loud enough. It's as if the R530 is filtering out anything under a certain volume level. I've turned off Call Equalizer and Noise Reduction to try to solve this problem. I believe I've read people say a firmware/ROM update from US Cellular fixed this problem.
So you can see, I have some constraints: Still in warranty and don't want to void it by tripping KNOX. Want to try a newer firmware for call audio problem. Don't want to brick phone with incompatible firmware, unless US Cellular will work on this X/Generic phone.
Help would be appreciated.
I do have the USC and Cricket variants but the USC version is soft bricked.
HW: R530C.01
Firmware: JSS15J.R530CVVUCMK3
Baseband: R530CVVUCMK3
Also fyi, this and the USC version requires a sim card.

Thanks... I'll add the info. I think I'll make a spot to record if it has a SIM slot too -- as my 530X does not have a SIM slot and was labeled with a little sticker "3G CDMA"... but the MEID starts with a "9" and LTE visible in DFS.

I have a regional version of the s3 as well, d2xar (sch-r530x) on Inland Cellular, primarily based in the north west US. as far as i can tell, i havent dissasembled my phone to see if there is a lte radio, in the original build.prop for my phone it is disabled on boot so it will not consume power since it is not being used. thus the 3g cdma only sticker. for the us cellular version i do not know if there is a kitkat firmware but if there is there is always the possiblity you will not beable to go back. as for the generic version it is only on 4.3 right now. eitherway the higher the bootloader version is better for customroms due to recoveries and features working better. as for saferoot i dont remember if it trips the warranty bit or not since ive long since written a custom recover to the device which tripped it but i do know itll make the stock rom list itself as custom in the settings after being rooted. also something to keep in mind with a custom rom is, unless you have the apns for your carrier eg, pageplus, usc, ect. you will not have mms capabilities. Im still tearing my build.prop and apn back up apart to see if i can include some of that info into a custom rom to fix mms, or a recovery that will inject it after a rom flash.
Update?

Last I checked there was a bug with the d2lte builds that break the ability to set apns... I made a cm10.2, I think, build that allowed changing the APN. Um if I remember right the physical design of the d2xar has hardware similar to the Verizon s3. I still don't know if there is an lte modem in the phone since there doesnt seem to be a sim card slot, though there maybe an integrated uicc. I haven't played with it much since I switched to using my nexus 5 on T-Mobile.

I got to the service mode settings, which oddly enough it listed GSM and CDMA. Quite weird. To get there was even weirder. Sadly the D2xar doesn't support TWRP Recovery, and the only one that works is CWM by Philz.

Yah I noticed that to when I was digging around for apns for my old carrier. As for twrp I got around that problem by building my own version using cyanogenmod and the d2lte device files. It made cyanogenmod delta updates possible on the d2lte build. Which are really nice. My source is floating around github, though you'd have to do a little digging to find everything. I do have precompiled twrp images on my webserver that I try to keep up to date for my friend who's brother has the same phone. If you go to my site its safe to ignore the certificate warnings, I have it set to force HTTPS and the reason the warning pops up is because I self signed it instead of paying for a company like verisign
Sorry for my superbly late reply. I've done a ton of digging with this phone. Turns out it only supports Evdo. So no LTE sadly. Even worse, using the Test Menu I can't bands to USA bands, only the (800 or 850?) Hz Global band. I can't get a connection. Well. The bars are listed as 2-3 generally, but it says "Roaming Indicator Off". I have the latest and only baseband, too.
(Wow. After two months of fiddling, as of typing this, I turned on cellular service, which is usually in Airplane mode, I got a " 3G" connection for the first time. Only for a second.)
I don't think I'll be able to switch this over to Straight Talk any time soon, though. I'll check your GitHub soon for that TWRP.

Yeah, just of now I've been unable to re-acquire the "3G" that caused me to have a boost of hope. Now even when I attempt calling which it usually would bring me to the Verizon automated system, asking to make a collect call, since around here is primarily Verizon, I can't even get it to call. It now states that no mobile network is available, even when I have 2-3 bars.
You have no "3g" because your keys are wrong. Y'all need some QPST and see the whole logon process and baseband messages. Then you can really troubleshoot your phone.
I have a Verizon Samsung Galaxy S3 on the Straight Talk network. I check for software updates and it tells me the software is up to date however it says my phone is running off of 4.4.2 instead of the Lollipop or the one just under. Does anyone know if Lollipop 5.0 or 5.1 has reached the S3 yet? Or how to manually update my phone software so its not so low?

you will have to root, trip knox and lose your warranty... there is no way to go back. on verizon you may be screwed if you have signed/locked bootloaders. search on XDA about unlocked bootloaders for verizon. also: http://androidforums.com/threads/verizon-verizon-bootloader-unlock.856221/
aaaand... make sure to back up your mmc boot partitions so you can debrick if you mess up.
p.s. prepare to learn a lot of technical things. if that sounds annoying and you don't want to spend a lot of time on it you might be better off buying a used phone.

Do you have any idea if the 530c and the 530x share a similar partition table? If they do then I can pull the one from my 530x

I do not know. I'd love to take the chance, but the risk of totally bricking the R530C is there . . . heck, let me try it.
Hi guys,
I have a white Galaxy S6 Edge 64 GB Sprint model, SM-G925P and lots of trouble. I did not buy it from Sprint, as I'm not from US, instead traded my black 32 GB SM-G925F for this model, which is the international model. Thought that 32 extra gigs would not hurt and that the white one would be less off a fingerprint magnet.
Unfortunately, during the trade, I did not pay attention to a very important aspect: mobile data. I checked voice calls, camera and wi-fi as well, thought that everything should be fine. Mobile data is available only while accesing the settings and does not show while sliding from the top of the phone for the control panel.
As I got home, I discovered afterwards that I cannot make the update from 5.0.2 to 5.1.1 and that I cannot change the language from English to Romanian. The next day, I took the phone to a GSM service and they made the 5.1.1 update and mobile data work. I still can toggle it on/off only in the settings. The big issue is that I can use only 3G mobile data and that upsets me a lot. Of course, the guy that I made the trade with isn´t anymore to reach. Please let me know if I can do anything about 4G. I am really pissed off right now. Thank you very much!
Hi,
I'm also wondering if there's something possible. I already tried QPST and QXDM for enabling more bands but it didn't work. I guess it's something with the modem. Since the 925F uses a different chipset than the 925P it's not possible to use that one, but I found out that the G9250 has the same chipset as the G925P and supports an extreme amount of bands (more than the 925F). But since our bootloader is locked it's not possible to flash the modem. And even then there could be a lot of problems. So we have to enable the bands in the modem.bin. But that's quite hard and I still haven't found out how to do it, but it's our only hope. (G9250 Bands: http://pdadb.net/index.php?m=specs&id=7836&c=samsung_sm-g9250_galaxy_s6_edge_td-lte_samsung_zero)
Thank you for your answer mkalter,
I am by no means a developer and never rooted a phone, but if there is any solution that won´t brick up the device, I'll gladly try it. It is very upsetting to know that I cannot use 4G on it just because a provider doesn´t want so. Had to learn the hard way to triple check a phone when trading it.
I just solved the issue by selling the phone. Mods can close the thread.
I will start off by saying I am not experienced when it comes to custom roms. I currently have an G930P running stock, but want to switch to a custom rom for better privacy. I did some research and was disappointed to find out that I can't do that with the G930P, so I ordered a "renewed" G930F from Amazon. It arrived today, but instead of the model I ordered, it appears that I received a G930W8. I know this is still an Exynos model, but I want to double check to make sure there aren't any issues I need to be aware of before trying anything with this model. I really don't want to brick a $200 phone. I'm leaning towards Havoc OS for my rom if that makes any difference.
Another question I have is whether this phone will work on T Mobile/Mint as my plan is to switch to them from Boost because I found out I can get a lot more for my money that way. I haven't been able to find as much information for this model as I did for the 930F.
Thank you in advance for any help.

So the G930W is customisable and anything you can do with an G930F you can do with G930W. The only thing you need to check BEFORE you do anything is to check network band compatibility. Look at the "Network" specs for both phones side by side and make sure the bands you need for TMobile are listed.
Also there is obviously a scam with these phones always being described as G930F but turning up as something else. It's true exynos models are easier to modify but you still need network compatibility as I've mentioned.

I checked compatibility with Mint/TMobile and it said 100% for 2g and 3g, but only 60% for 4g. Went ahead and popped in the sim card that just came in the mail and followed the instructions for activation, all except for one step which said to turn on mobile data, which I couldn't find in the settings.*This did not get me connected, so I looked around more in the phone's settings and found "Network operators" under the "Mobile networks" page and hit "Search networks." This pulled up 8 different options, all called "Mint." I tried "select automatically" but I got a message saying I would have to manually select the network. So I started going down the list, trying each one. Some of them would not connect, but a few did and would show several bars of signal. But when I would try sending a text or making a call, I would get an error.
I should probably also mention that in addition to frequencycheck.com, I also checked the phone's compatibility via Mint's own website which asked for the phone's IMEI and it showed as compatible, but also said this wasn't a guarantee that it would actually work.

Hi there @ekjf, I was wondering if you tried installing a custom ROM on your G930W8? And did it work?
Thanks!
Hi all,
I have been stay up two days to looking for my solutions and would you guys at least let me know if this is impossible or possible?
1. Bought Global Unlocked AT&T phone from my friend. When he sold it to me, I made sure it is unlocked and move to any carriers.
2. I check IMEI numbers and everything from Verizon (I called them) they confirmed this phone is compatible in their netowrk and will work.
3. I switch my iphone 11 max pro sim card (verison) and put it to Samsung Z flip 3 5g.
4. Everything works find but, I saw AT&T logo when I start the phone. I also some of AT&T setting's everywhere. I did factory format and showing the same thing.
5. I called verzion and they said, because I use 4g sim to 5g phone and asked me to visit their direct retailer to get free 5g sim card and I did.
6. HOWEVER, after change even sim, it shows still AT&T logo and AT&T related menu in the settings and everywhere. Also, I did not even have wifi calling feaatures.
6. After that I have been search and study two days but, still couldnt' figure out what's going on. What I found is I need ask my current carrier to push OTA. (that's the one of other people suggested and I did chat with verizon and they said, they will get back to me after senior engineer to check if they can do it.
7. They also make sure my phone is registered their networks and works fine.
It is really bothering me to see some of AT&T settings still turn on and also shwoing in this phone.
Probably this phone is global unlocked phones provided from AT&T from the beginning.
While i am searching and reading the articles, lots of people told me to gave up because i am even on Verizon, they said I have to depends on AT&T's OTA updates and etc....
it is my fault to bought it from my friend even tho I belived that because it worked, I thoguht that everyhthing would be fine......
What should I have to do? Just stay with it and sell it when z flip 4 is come out? Do I really didn't have any change to correct this issue?
I was fan of iphone and i swiched to android first in my life and everything went wrong. I want to fix and stay on Samsung. Would you guys can at least let me know there's no way or there's way to correct this so that at least I can ignore everthing and stop trying to find answer all day wrong........
Thank you and sorry for long question... you guys are my last hope.
Thank you in advance.
