Flashing VZN MZ600 with HTJ85B(USA_Wifi_3.2) - Xoom General

I flashed my MZ600, with HTJ85B(USA_Wifi_3.2) using images/steps from post bellow and tablet works fine!
http://forum.xda-developers.com/showthread.php?t=1080963
Obviously there is no sign of "3G CDMA network" but for me, that was useless already, since I am in europe (UMTS).
I have asked this question many times, without a proper answer: why can't we switch basebands ?(since there is no proof of different hardware between US and EU xooms)?
why are there not any radio.img from US/EU versions so we can play/hack ?
Other moto tablets/phones even have apps for changing basebands from android!
If someone "experienced" creates a baseband backup, I am brave enough to do attempt the flash
Furthermore, I have some app-development experience, hence if needed I could develop an app for easy baseband switch.

How easy is it to install a custom ROM on the p1000?

I have an LG Optimus One and custom ROMs can't get any easier. It's just root with z4root, install Clockwork recovery with ROM Manager and flash away. I'm not yet familiar with the other aspects of rooting and installing. So I ask how easy is it on this device? I might pick one up soon since it seems to be getting cheaper and cheaper...
It's really simple. Same app to root, then use the Odin program to flash while in download mode. Instructions here.
I'm still a beginner when it comes to Modding and this was a cakewalk.
Sent from my GT-P1000 using XDA
Ok sounds good. But what does GSM and CDMA mean? How would you know what kind of Tab you got (I'm assuming these are hardware related since the roms have only one or the other)? And what does the modem have to do with anything?
I didn't have these terms involved with my O1 so I'm not sure yet what they do... At least I know to avoid the Wifi only p1010 since it isnt as developed for (really important to me).
gsm/cdma is about cellular networks, if you have a simcard slot then your a gsm, cdma is without one, the service company can provide you service without one, its mostly a USA thing, sprint, verizon etc, not sure about Europe,
look at the back of your tab and tell us your model no. i have a p1000t, but this tread states you have a p1000 so i assume you have a gsm one.
sorry if its not too informative.
Practice makes Perfect
All custom ROM providers these days seem to suggest you follow the Overcome Guide. This guide was the one I followed to start with and it is very clear. Go to the teamovercome.net website and look at the guide.
I can do this now from memory, and have used the same method to flash ICS, Hyperdroid, and Overcome.
It's a great guide - flash and enjoy!

[Q] i9505 - Difference between GSM and LTE modem?

I've seen people saying they have a baseband for GSM and another for LTE. Where can I see this? All I see in "About phone" is "Baseband". It doesnt say specific for GSM or LTE.
And How can I get different basebands for each radio? In baseband collection thread all of them are just 1 zip file, so it updates both, right?

anyone?
I see .zip packages that are supposed to upgrade GSM modem to one specific version and LTE to other version at the same time. Where can I check that?

Thank you!
I was thinking that as well, but in Omega ROM's thread there is a zip file that flashes a modem for GSM and another for LTE
**If you are having the old bootloader XXUB flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUBMH1.tar file with odin by selecting phone.
**If you are having the new bootloader XXUD flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUEMJ5.tar file with odin by selecting phone.
That's why I'm asking.
Any idea?
You shouldn't need to touch/flash another LTE modem unless you have problems, the one already on the device should work just fine. I don't know specifically what might be in Omega rom to require those instructions as I've never used it, but I'm running XXUEMJ5 GSM modem with the 'old' bootloader on Foxhound 3.1, and everything is working as it it should. I've never touched the LTE modem/the one that was on the device when I bought it is still on it & LTE works fine in areas where my carrier has LTE coverage.
If you're about to flash Omega rom, I'd say follow the instructions (or ask in the thread), if you're not, I (your mileage might vary though, obviously) wouldn't touch the LTE modem at all unless you have problems with LTE connectivity, WiFi or sound.
Edit - Going back through some posts/threads I have bookmarked from months ago, people who messed around with non-HLOS.bin files seemed to have a funny habit of borking their WiFi & other stuff. As I said above, I wouldn't be flashing one separately unless you had a good reason to (I.E something like the Omega thing where it's a specific instruction as part of flashing the rom), or flashing a rom/something else borks your WiFi/LTE/sound or whatever as I said above, the one already on your phone should do the job.

thank you vey much, but....
too late hahaha I've read your post right after flashing that zip. Everything seems fine but can't test LTE yet because my plan doesnt support it. I'll try to upgrade to LTE this week and I'll search for a method to revert LTE baseband if I need it in the future.
Thanks again sir.

Canadian i337m compatible marshmallow roms?

Ok I'm just a little confused.
Canadian i337m compatible marshmallow roms?
Are they jflteatt jfltexx i9505 or something else or all of the above.
(I'm running wamanlite 4.4.2 9505 rom now on my jfltecan I don't think there are any good links for it left, and when I flash a new one there will be no going back)
I know there are others confused out there as well..
If you are using marshmallow and you have flashed the rom to your Canadian s4 and all is working great.
Please post a link to that rom here
If you needed some other kernel or file to flash in to make it work
Please post that info with links also.
Thanks for any info you can provide.
(And bite me Samsung att and others for locking so many U.S. carrier boot loaders which has reduced development)
The s4 should work with the 9505, jflteatt, and jfltexx ROMs; however, editing the updater script may be required to get the ROM to install.
Hahaha - you will likely get yelled at to use the search bar and to read the stickies with these sorts of questions, but I was a noob once too, so here's an olive branch. (that being said, please do use these in the future!)
Your i337m will be cross-compatible with ALL GS4 devices (at least to my knowledge). I've had one now for a little over 4 months and have explored most of the options available to the Canadian variant. I have run everything from 4.2.2 to 5.1.1 on my device successfully, but you will have the most luck where the developer indicates that the build is for jflte devices in general, not one in particular.
Furthermore, the GS4 or ANY device sporting a Qualcomm chipset can use a modified modem file to access WCDMA/HSPA bands (ie. WIND, or T-Mobile).
Again, the search bar is your friend here! Also try Google, or Duckduckgo (google will tailor your results, sometimes in a way which will actually hinder your search).
If all else fails, send me a PM and I will assist you wherever possible.
Best of luck!

Just wondering what modem to use. Do I use the latest modem for I337M or can I use modem for I9505. I live in Canada and have always used the modems for the I337M model. The latest modem is PA1, I think for the I9505.
Hey tvsite,
Modems for this phone in Canada puzzled me for quite some time, however, this is what I did to make things work.
--> Downgraded from 5.1.1 CM 12.1 Optimized via odin using "I337MVLUAMDJ_I337MOYAAMDJ_VMC.zip" (http://www.sammobile.com/firmwares/download/14412/I337MVLUAMDJ_I337MOYAAMDJ_VMC/)to net me 4.2.2 (note: your wifi or calling WILL NOT WORK).
You may have even better luck using the SaskTel firmware at this point, although I have not tried it yet. (http://www.sammobile.com/firmwares/download/14418/I337MVLUAMDJ_I337MOYAAMDJ_BWA/)
--> Do the AWS mod, unlocking etc.
--> Upgraded to 4.4.1 using "I337MVLUFNC1_880525_REV06_user_low_ship_MULTI.tar"
https://mega.co.nz/#!h8pTnCZS!t2-PiSb5W9ZyNp7fct7WD_Pg_dnc-eZqtMvpsuKv_9Q
--> I forget what modem I was on at this point, however, after letting OTA do its thing, I wound up at 5.0.1, OH1 modem, and AWS still enabled.
Good luck!

I flashed the OK1 modem which is posted, here, which is for the I337M model. I believe this is country code Mexico. This modem is working fine. Have you tried flashing a I9505 modem using Odin. I tried and it said "failed", so I may have answered my own question---that you cannot flash modems over different model numbers even though its the same phone, ie. S4

After Nougat update with Polish PLAY operator no International roaming

Hi guys,
I (we) desperately need help. Myself and a number of other Moto X Style are crying out loud for help on getting our roaming issue fixed. Long story short:
I have a Motorola X Style (all original, no mods), after the upgrade to Nougat International roaming stopped working (it was working on 6.0). Or better, international roaming does not work with a SIM from a Polish operator named PLAY. Funny enough the same SIM in another phone roams internationally fine and a SIM from another operator in the Moto X roams fine too. It seems to be a sick combination of Moto X Android 7.0 and PLAY. I (we) have tried everything, theres a thread on the official Motorola forum if you dare to read ( I cannot post the link because I'm new, but a search for "Moto X Roaming not working Polish Play" will give you a link). And when I say everything I really mean it... Starting from Clear the Cache to Factory Reset, and the obvious/trivial things too like "enable data while roaming" etc... According to the PLAY provider all is OK on their side and Motorola is ignoring the issue... Its 8 months that their "engineers" are allegedly looking into it, and that it will be "hopefully resolved in future updates" .... yeahhh believe it... Solution from Motorola: "send the phone in for a downgrade to 6.0". Many of us, me included, are locked into a # of years contract with PLAY so it is not that easy to dump the operator and go with someone else. That's why someone with a real deep knowledge on how this stuff work is needed. The last thing to add is that PLAY operator is one of the few that uses national roaming too to fill in the gaps on their national coverage, needless to say that national roaming works fine.
Any help will be really appreciated ... best regards Fulvio.
There's not much we can do about it. Editing the stock modem is nearly impossible.
Best you can do right now is flash Nougat Custom ROMs that are based on Marshmallow modem (Official LineageOS), In this way you'll get the Nougat features on Marshmallow base.
or.. try flashing other variants nougat modem RETUS, RETLA (this is not recommended and has a high risk)

RetLA & RetUS will not work in Europe, RetAsia has the same baseband.
I think @fulvy70 has locked bootloader so he can't flash anythng.

Yes of course he has to unlock first and if the device is out of warranty, I don't see any harm in doing it.
Me to.
Someone here uses MM when he's on travels and Nougat at home.
Because...
Delta app doesn't work good on Nougat.
Hi,
Thank you for your answers... I understand that you are all pinpointing the issue in the Modem/Radio Firmware, not the Android OS itself ... this is already a step forward... I understand the risks connected with flashing a different Modem/Radio FW but anyhow is something to know ... I believe it is also something to consider if eventually any custom ROM will be compatible with the new modems/radios ... at that point even changing the ROM to custom will not solve the issue I believe...
Regards Fulvio.
Flashing custom rom doesn't change the modem/radio/baseband.
I don't know where is problem - only Play(Poland) doesn't support LTE roaming.
You can flash any custom for N modem and check it. @fulvy70

AT&T Wifi Calling on ROOTED T-Mobile S5

Hi,
I recently bought a T-Mobile S5 (SM-G900T). It's unlocked and I rooted and de-bloated the stock marshmallow ROM. The phone works wonderfully and it was nice getting a brand new phone that meets all my criteria (runs Google Maps fine, removable battery, SD Card, rootable) for under $150.
I use AT&T for my service. I'm wondering if anyone can tell me how to get AT&T Wifi calling working on this phone. The phone is rooted so I'm sure it's definitely possible with enough work but I'd like to know if anyone has already done this.
Thank you.
PS: please don't ask why I didn't get an SM-G900A. I didn't and what's done is done. Return/exchange period is over
If your on ATT prepaid as I am, same phone, they do not support it, only post paid can use that service. Was just at ATT store changing a battery and asked while there.

Thanks but I don't see any mention of AT&T Wifi calling on any of those T-Mobile ROMs. Maybe I missed something? In either case, I'd prefer not to switch ROMs but I could use it to see what was done to make AT&T Wifi calling work.
I'm not actually interested in phone calls with wifi calling. I want to receive text messages at work where I have no signal.

When you say you'd prefer not to switch ROMs, is it because you prefer running the stock / official ROM? Or is it because you don't want to go through the process?
The US Snapdragon variants of the S5 have the same hardware, they're just tuned differently via the EFS/modem settings and run different firmware images based on carrier. You can run a different carrier firmware on your device just fine. I recently completed a switch over on a SM-G900P (Sprint variant) to the SM-G900T (T-Mobile) software. All T-Mobile specific features, including Wi-Fi Calling, are functional as if it was a T-Mobile variant.
What I'm proposing is, if you like the stock software, you can have it, with AT&T features instead of T-Mobile. It'll function exactly as if it were an AT&T variant, purchased as such, rather than as a T-Mobile variant.
The process I used should be applicable to any Snapdragon variant, however. As I had to figure out much of this process for myself, there's no guides or information out there presently. But if you'd like, I could help you through the process.

Now, there's an interesting suggestion! Are you saying I can get the SM-G900A firmware from sammobile (or some other source) and just ODIN flash that to my SM-G900T? If so, that would give me AT&T wifi-calling. I was under the impression that there were hardware differences and that you couldn't flash firmware from one variant to another or you'd end up with a brick. I guess that's not true?
I don't particularly *like* the stock firmware but I just want something that will work well with the least amount of tweaking. I'll de-bloat myself it but top speed is not as much of a priority as battery life and all phone functions (camera, bluetooth) working as it did from the factory. So, (debloated) stock is good enough for me.
Thanks!

Well, any stock firmware is as close to factory functionality as possible. When switching carrier firmware, you gain the features of the target firmware, without any bugs or other problems.
You do have to take care in doing it correctly. It's not meant to be done on an S5, and there's no documented method out there, such as Prince Comsy's Odin for the S7, for example. Also in regards to that, the flash is not done via Odin. There's some parts which require it, however, there's no way to flash a full other carrier firmware via Odin on an S5, as far as I know. The device bootloader rejects the firmware due to a software check failure.
That aside, if done correctly, it functions identically to the desired firmware variant in my testing.
There are only two things you need to concern yourself with. The first is whether your device presently has the proper frequencies activated in its EFS configuration. If not, you won't receive coverage where the bands used aren't active on your phone. If this is a problem, it is possible to manually activate additional frequencies via QPST and QXDM. You may also desire to do this anyways, for increased roaming compatibility and coverage. This is another thing you have to be careful while doing, however.
The second thing to consider, is whether you care about OTA updates. Or more precisely, that you won't be able to use them. This is arguably of little consequence, as its unlikely anymore updates will be released for the S5. But if there is an update, you'll have to apply it manually by the same process used to convert your firmware variant. If you were to accept an OTA, it could brick your phone. This is due to the fact that we don't flash the boodloader from other variants, for safety reasons. An OTA update would likely apply (or attempt to apply) the bootloader from the converted firmware. The outcome of this is unknown. It's possible that it works without issue, but if it doesn't, it has the potential to hard brick the device. For this reason, I haven't tested it, as other firmwares can be loaded by a mismatched bootloader without issue. Due to that, I recommend disabling all OTA checks / settings for additional safety. As a note, updates via Kies, Smart Switch, Odin, or any other utility are also a no-go. Updates must be applied manually if you want them.
If neither of those two things is a problem for you, then you might be happy with converting your firmware to another variant. It does work quite well when done correctly.
If you're interested in doing this, I could guide you through the process. It would be more convenient via instant messaging, so we could directly communicate in real time for the parts that will be specific to your device.
If you would like to, send me a PM to coordinate IM details. I use Telegram and Wire, and if neither is suitable for you, and you're okay exchanging phone numbers, I also use Signal if you'd prefer. I also use some other services as well, though I less prefer them. If none if the above are suitable, perhaps we can find one we have in common.

I could be wrong here but, based upon what I had read (my take on it), I don't believe that @Arbiter was recommending that you install the stock firmware rather an option that Arbiter had suggested to see if the WiFi Calling option is made available (based upon that members experience).

To clarify, I'm suggesting that if you want all carrier specific features (including Wi-Fi Calling), it can be done by cross-flashing the target carrier's firmware.
If the target firmware is correctly installed, and the corresponding CSC is properly installed in both the support files and configured in EFS (a simple three letter change to a file on the EFS partition), then all features for that carrier will be available.
This is the only way I know to achieve full functionality with another carrier's features. There doesn't appear to be any available research or success in simply transplanting the necessary programs and libraries to handle carrier features on a non-carrier ROM for the S5.

I apologize for my misunderstanding but, I will have to "Respectfully Disagree" with you.
Though Custom Firmwares may be lacking some/many of the carrier specific apps and those features these apps utilize but, there's ways to obtain them either directly or indirectly via installing, flashing and/or porting them to a device.
Just to clarify... I'm not stating that this applies to all carrier specific apps and/or features but, I've seen this done for many of them on a Verizon S5 device with a custom firmware installed.
Maybe we just have to end this respectfully with "Agreeing to Disagree"... :thumbup:

I DO NOT provide support via PM unless asked/requested by myself. PLEASE keep it in the threads where everyone can share.

Since you've seen this done, would you point us towards the correct direction in order to get at&t wifi calling on a G900T-based stock (or non-stock) OS? I have been trying different techniques and have only succeeded in causing bootloops :\
I don't want to use a bootloader locked G900A OS.
