Hello!
I am new here. Actually, both, here and in Android world (was on iPhone up to - recently :{))
Sooo, after i manage to break (literally, BREAK) my iPhone, I got a tablet as a present.
It is NTT DOCOMO SC-02D tablet, - basicaly, it is Samsung Galaxy Tab 7.0 plus.
So, I got a tablet FULL of very unusefull stuff from DOCOMO.
However, since i am not in Japan, and I am still able to use my t-com network to make phone-calls through sim card, and also, I can connect to wifi networks here - it (my tablet) is either unlocked, or something (marriage - like) happened with world's biggest providers of mobile phone services :{D.
I am completely new to Android and I am actually totally in the dark here. And, guess what: forums doesn't help much, since I can get instructions and tutorials about anything, but as fragments that I just cannot connect to be sure I am doing things right.
So, here goes my question:
I want to erase all docomo software and system from my tablet and install new and fresh android, that I can fill and use as i please!!
Basically, I want to reinstall my tablet. How to do that??
What I learned so far is all about rooting and unlocking, but I don't think I could find instructions to INSTALL ANDROID FRESH anywhere.
One other thing, - I DID FIND SUPERUSER icon in my apps, so does it means somebody rooted my tablet already?
Main reason for me not already trying anything is because I saw that my baseband version is sc02domkk9 - which means it is something of docomo ... So, since I had a problem with my iPhone, when I updated my baseband and therefore couldn't use wifi for a month or so - I need to be sure it won't happen again - that or bricking my tab ...
Thanx in advance for all Your participation in this thread ...
C'mon, guys, nobody??
Well, can someone please tell me is there any way to UNINSTALL apps that are DOCOMO's? I don't get option to uninstall them regulary ...
Ok, can anyone advice me on what ROM can i install on my device??
NTT DOCOMO Samsung Galaxy Tab 7.0 plus
As You can see, - learning in my walk:{D
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.

I am on a post-paid family plan. Wifi calling is definitely supported. I've used it on other AT&T devices.

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).
Am I correct @Arbiter?

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:

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.
Good morning all,
I'm a returning member from quite a few years back, haven't loaded a ROM or rooted an Android device in years. My question is this, I have a S10+ G975U and working in IT, have some security based concerns with this (and any) device:
Items installed against my will (COVID trackers, etc)
Access given to bloatware that is not able to be uninstalled (AR programs, etc)
Bloatware I don't want or need
Given this, I also understand the necessity of keeping devices up-to-date and check firmware updates on a near daily basis. Is there a root/ROM that will allow me better control, security, ability to control what apps/features are installed and stay up to date in a reasonable manner?
Thanks ahead.
Not on the G975U with a locked bootloader. Root nor a custom ROM is possible.

Crap, well, guess I need a new device in the near future. Guess I'll post up for recommendations. I want something within these specs that gives me the most control over data, privacy and what is and isn't on the phone.
