[Q] Tethering and Video Calls on Samsung Focus Flash

So I live in Mexico and just bought a Focus Flash...
I tried to use it as a hotspot but I couldn't... My carrier supports tethering and it uses the same bands as at&t...
When I try to use the internet sharing options it shows a message saying that I have to call at&t...
Does anyone knows how to make this option work outside of the US?
Also, I have a similar problem when I try to use the samsung's video call app.
It shows a message saying my device isn't supported, is this also because I'm using it with a different carrier?
I hope someone can help, thanks! =)
If I can't find a solution for this, I'll probably start looking for roms from different countries to see if flashing it helps.

I don't know about the video call app. As for the other, however...
First of all, if you're using an AT&T ROM (which it sounds like you are) and you can find a way to flash an "International" ROM to it, I'd suggest you do that. AT&T puts a lot of restrictions on their phones that you, as a non-customer, have no reason to put up with (personally, I don't see any reason for their customers to put up with it either, but that's another issue).
Beyond that, if by some lucky chance your current firmware is compatible with WindowBreak, or at least you have a backup with old enough firmware, then yes, it is possible to strip out all of the limitations on the "Internet Sharing" feature. For one example, search the Dev&Hacking sub-forum for "Interop Unlock + Internet Sharing".
Beyond that... you'll either need to exchange your phone, find some other way around the problem (for example, you should be able to use wired tethering; it's unofficial but available for most if not all Windows phones if you know where to look), or wait until we find new hacks. Any of the following would work: a way to interop-unlock gen2 Samsung phones with current firmware (install WP7 Root Tools and use a provxml processing app), a way to flash a stock ROM to gen2 Samsungs (either replace your current ROM with an international one, or downgrade it to one that is compatible with WindowBreak), or a way to flash custom ROMs (which all come with this feature fully enabled).

Well... it was HAAARD D:
But I finally got to tango with tethering and it seems that I'll be able to get the last firmware update as well =D
So it is all good... I'm still using the at&t rom
I don't have video calls but I don't think I need them that much... If I want to have videochat I'll just use skype =)
Thanks for your answer, man =)

Hi,
I am rather new at android. I recently acquired used Samsung Galaxy S5830. Hardware is in excellent condition, however firmware and software area real mess. The phone seems to have Cynogenmod as a custom ROM installed which I find annoying and there are bunch of apps that I don't dare removing not knowing what they are while basic things are missing including possibility to add Samsung account, email client, gmail client, maps, Samsung apps, navigation etc.... I would like to get the phone either back to its original state or some other custom ROM that would include all (and only) original Samsung applications that originally came with the phone or some other Samsung model, in particular Goggle maps, navigation email and gmail clients..
I have found appropriate USB drivers, installed them, appropriate tar.md5 file, installed Odin 3.7, put the phone in download mode and tried to do it myself. However, Odin creates a port but fails each time, I get no yellow or green where its supposed to be. I am not using the phone yet, so I don't mind wiping it all, no backup is needed.
I understand that before the process USB debugging should be enabled, but I couldn't find the way how. Pointing to Manage Apps> All>Dev. Tools, all I get is App info and an option to force stop it.
I'd appreciate all the help I can get.
Thx

First activate developer options by tapping on build number in the "about device" in settings. When it's activated, you will find the usb debugging tab in developer options.

Thank you, but....
As I have mentioned, the phone is a mess. The thing you are suggesting is simply not availanle. It is there but shaded out. Going to About phone all options I get are Status (Phone number, sigal etc.), Partition info, View changelog, Legal information and following shaded options: Model number (GT-S5830), Android version (4.2.2), Baseband version (S5830XWKT8), Kernel version ([email protected] #1), CPU, Memory (277 MB), CyanogenMod version 10.1.0-RC4-GT-S5830-cooper, Build date and Build number.

[Q] SGH-1497 enable screen mirroring

The wifi only model of this tablet running 4.1.2 has screen mirroring capability. However AT&T in their "infinite wisdom" decided to leave it out. I am looking for hopefully just a quick and dirty hack to enable it. Here are possible solutions in order of what I would like. I will accept any answer that get the feature, but I would like to not have to put some completely different custom ROM on it as it is for my dad and he is used to the interface as is. Thanks all for reading.
1. The stuff is all there and they just disabled it (maybe just edit a file after rooting the device)
2. They left out some files to offer screen mirroring (just copy some files over after rooting device)
3. Putting a custom ROM on (as long as I can get play store and all other normal functions)

I was thinking, does anyone have the stock firmware for the wifi only version of this? I was going to get that and get the firmware for this AT&T one and see what files the wifi version has that the AT&T one is missing. I tried searching online but it is old and all the links I find aren't there. The only model I can find is the 5113 which seems like a foreign version because all of the firmwares are from some other bloody country. I need the US version since the 1497 has the US version. Please help

Advice to flash z3 D6653 to NTT DoCoMo SO-01G

Hi
I bought a z3 D6653. It has Customized_TW rom in it.
As I live in Japan I went to Docomo to upgrade my current contract to use it.
They made a SIM card, which worked for pone calls but not for data. After checking the phone they showed me that the D6653 does not have the Japanese wireless certification (it has US, EU and not surprisingly Taiwan)
So off course they cancelled the new SIM and I'm back with my old phone.
I checked a lot the forums and other websites and it looks like that by just flashing I could solve the issue. As I'm new to Sony Xperia I have few questions:
- I saw many people saying flashing a D6603 rom on a D6653 works just fine. That would solve the wireless certification issue because the D6603 shows the Japanese one. However I think that unless I flash to the Docomo branded rom (SO-01G, not D6603) I won't be able to use my docomo mail address. Has anyone ever tried this ? Is it safe (the only difference i see on the SO-01G compared to the D6603 is the bigger 32Gb memory and the oneseg TV)
- in flashtool, when creating a bundle, should I choose the original device (D6653) or the device for which the rom I'm trying to flash was created for (D6603 or SO-01G)
- finally in general, how risky is it to flash ? I backed up my original rom the Sony PC companion downloaded (and created an FTF with it). Is there any chance that after an unsuccessful flashing in flashtool I can't revert to it (either using flashtool or the PC companion) ?
Sorry for the newbie questions....any help would be greatly appreciated.

There is a reason people warn you excessively about jumping between other carriers and other region roms. Someone has to check them for compatibility. In this case, for damn good reason. The SO-01G uses a different partition table to have space to support the country specific features provided by their Japanese carrier, and add other features like 1SEG support. This partition table corresponds to a 32gb model. Someone FAR more skilled than I could maybe help you take an extracted partition table from a Z3 docomo ROM and help you adapt it to fit a 16gb phone perhaps. But that is not particularly easy.
Now, THAT SAID, if you were to do that somehow, and expand the system partition so it would fit the docomo system partition, you may be able to flash it using Flashtool, being careful to ONLY flash SYSTEM and KERNEL and not PARTITION, and making sure your RECOVERY and BOOTLOADER are not anywhere near the blocks you are overwriting on the memory.
For Japanese phones, using foreign roms is not too hard as long as they exclude partitions. Their default system partition is large enough to fit foreign roms, but NOT vice-versa. You NEED to adjust your partition before flashing Docomo is an option.
edit: actually, if you were willing to extract both from their respective FTF files and make the comparison, you can make the call on how safe this is for you. I know it goes one way, but so far you are the very first person I've heard wanting to go the other way.
Overall though, you should skip the flashing nonsense, keep your western phone, and go to a SIM reseller. Hit up a K's Denki or Yamada Denki, or BIC Camera or Yodobashi Camera. ONE of them will have a sim carrier who sells you 7gb and ￥30 per minute for about $60 a month. Buy that and slam it in. Having a cell phone email address is over-rated.

Thanks for the detailed answer. I've had actually solved the matter differently in the meantime.
Should anyone have the same problem as I did, let me explain just a little more:
- I needed to keep the same phone number and email
- The previous contract was not even 3G so the SIM had to be upgraded (besides switching from micro to nano)
- Docomo was requesting me to have a phone with the logo of the Japanese Radiowave authority (sorry not sure how to say in English), which didn't show on the Taiwanese ROM of the D6653.
In the end what I did is to flash the phone to a generic UK ROM (so it showed as a D6603, if i remmeber correctly). This made Docomo happy because the RF authority logo was here. But then, since it didn't have any of the Docomo Apps on it (or wasn't bought in a Docomo store), I could not use the default Docomo ISP, so the phone was working, but neither the internet nor the email.
After about 2 hours in the Docomo shop, inisisting very heavily on many occasions, it worked. If someone finds himself in the same situation:
- Request the staff to not use the Docomo default ISP, but mopera instead (mopera is usually the ISP for 3G/4G USB dongles and other data cards). It costs about 500 yens/month.
- Add the staff to add an option which allows you to continue to use your existing email address even after leaving the current ISP (about 200 yens/months)
- Make your Docomo mail accessible through IMAP, check it works on a PC, then set it up on the phone. Make sure to push emails to the phone.
So there are some extra costs (500+200), but since you quit the old ISP you save 600, so no big change in the end.
Finally, I did not make any really accurate test of this, but using mopera instead of the default ISP *seems* faster. It would make sense since mopera is more business oriented than consumer oriented, but again I do not have any accurate evidence to back this.

Galaxy s6 (g920x) working on rom g920i help me

Hi guys, how are you? First of all, I am Brazilian and I am typing this the translator, so it may be a little difficult to understand this but I will try to explain my problem as clear as possible.
Come on:
Recently, I bought a Galaxy S6 model G920X Live Demo Unit written not for sale. But the curious thing is that, first, I did not notice that it was indeed a Live Demo Unit, and second: it was working normal network! He was in version 5.1.1 of the Brazilian rom G920I and could not upgrade over the air, because of the divergence between the device type and model of rom. Then I had the (stupid) brilliant idea to update it via Smart Switch to the latest version 6.0.1. The installation was successful, kept my normal files, but the network crashed. The device is with an IMEI (I can not say that it is because Live Demo do not record the device IMEI) and he recognizes my SIMCARD, including my number, but is "Just Call Emergency". I tried many tutorials, videos on Youtube, including various tutorials found right here at XDA, but tutorials that teach you to take the Live Demo version and make the device usable, always making it clear that the chip will not work. I hate myself for doing this sh * t, cause I had a device running normally and all wanted to update it. I have not tried anything about STOCK ROM still up because I'm afraid of making things worse and you can not install a standard version without Live Demo, and was wondering if anyone here has passed or know something about it, because I do not know what to do.
