Simple questions about flashing ROMS and whatnot for the S7 - Samsung Galaxy S7 Questions and Answers

So i got a Galaxy s7 from rogers here in canada. My model is SM-G930W8. I'm wondering how/what are the effects of flashing ROM on this device? Rogers is super slow with their updates, im still on their April update, and it's in fact the only update they ever put out. So if i flash a stock rom onto this phone, will i get the updates directly from samsung? How does this all work? Also if yall are too lazy to answer can you link me to like a good Q&A thread that would answer my question?

Well, I'm no expert in that area since in my country there aren't any carrier locked s7 devices. But I'm guessing that flashing a different stock rom might not be a good idea because you might lose some features or in the worst case scenario, your phone might not boot up at all. So, if I were you I would root my phone, search for a custom rom that's as close to the stock one and which can be flashed on Canadian models.

If you flash a rom from the dev section you won't get any updates since the phone will be rooted, you'll have to rely on newer roms from the dev section. You'll also lose volte/wifi calling from rogers.
Now if you flash a stock telus rom and have a rogers sim i doubt you'll get updates either but who knows, only rogers is holding up the update, every other carrier already pushed out the july update.

Tmobile Radio for official ICS update

I have tried a bunch of radio\modems that worked in GB and cant my phone to recognize one of them on the official ICS. I have also tried several of the ICS modems including blaze, telus, and several others, and can't them to work either. My sim isant found and under baseband version it says "unknown." Does anyone know of a tmobile modem I can get to work on my skyrocket with official ICS? Thanks for any help.
Even your question doesn't make sense ... What is your phone ? what rom are you using ? are you on t mobile SIM or what ? how did you update to ICS ?
Don't just throw 20 words and want an answer ....

If your going to be rude then don't reply to my thread. This isant hard to figure out from what I posted. I am on the skyrocket sgh-i727, hence why im posting in the skyrocket forum. It says in the title, I am on the stock ICS 4.0.4 rom. And I as far as I know there is only one offical 4.0.4 upgrade. And it would only make sense that I have a tmobile sim, hense why I am asking if anyone knows of a working tmobile modem for the official stock ICS rom upgrade. I have had a million phones, been part of a million different parts of XDA, and by far the people in the skyrocket section are the rudest. And before you say it, yes Ive searched, and searched, and searched again, but seeing as how it was just released yesterday, there is not alot of information out about it yet. After some thought, maybe it was possible you thought I was on rogers or something? Do people try to use tmobile modems on rogers versions?I dont know, but thats not important right now. But you could of been nicer about it. People with questions get treated like second class citizens around here. I updated by flashing using ODIN.

Restoring stock recovery?

Hi,
I have the Japanese S2 LTE, for which there appear to be no custom ROMs. So I'll have to (urgh, this is not why I bought an Android phone) use the carrier's ROM. BUT when I try to do an OTA update, it boots into CWM. I assume this is because the OTA update is setup to work with the stock recovery. So does anyone know where I can get the stock recovery from? I assume I'll need to use Odin?
edit: more info:
Model: SC-03D
Android version: 2.3.6
Baseband: SC03SOMLB9
Kernel: 2.6.35.11-SC03DOMLB9-CL980106
[email protected] #2
Build number: gingerbread.OMLB9
Also, I'm pretty sure the recovery will be the same as the Skyrocket. Almost everything about the phones is the same, save for the buttons and LTE chip.
TIA
Not sure of your model number, but a quick Google search came up with this...

Thanks for the reply. Sorry, SC-03D. It's the Japanese LTE model on Docomo. The LTE radio is different, and it only has one hard button with two touch buttons (like the original Galaxy S).
That thread is titled just Galaxy S 2 - will that work on an LTE?

For any future reference - I found a complete stock Docomo ROM on SamMobile and flashed it in Odin. My phone is now being treated (by Kies/OTA update) as a fully up to date, unmodified phone. Not that that really helps, Docomo still haven't released ICS. In October 2012. Still on Gingerbread. Yep.

Update to Jelly Bean if Rooted?

Hi all, I have the Verizon GS3 (SCH-I535). When I first got it, I flashed it using this guide - I apparently installed a rom by invisiblek that stripped out a lot of the applications. Well, since I'm a first time smartphone user, I asked in that thread that since my G3 was now rooted if I should accept OTA updates in the future, to which one person told me no. Last night I got a notification that my phone wanted to update to Jelly Bean, so now I'm not sure what to do. I don't accept the update because it will brick my phone, right? And if that's the case, where do I download a rooted version of Jelly Bean for it? (I searched this forum but couldn't really find anything other than people's custom versions, like Slimbean). I'm really confused with all the different rom versions available for the different carriers and models, though I suspect I can only use one for Verizon. Side question too - "rooted" is a modified version of an official OS release, right? It's not a method of installing an OS, it's an actual modified version, right? And if I want Jelly Bean, I have to continue using these modified versions, right?

Jellybean has not been officially released in any capacity to the Verizon GSIII. The update you see is roughly 30mb at the most, it's an incremental update at best from when you purchased the phone. No, it will not brick your phone. If you have a custom recovery then the update will fail. If you do not have a custom recovery then the update will unroot and unlock the bootloader and install successfully. We're months away from a Verizon update to Jellybean.

Download custom roms from the development section. Only flash roms for the Verizon GSIII aka d2vzw. These custom roms are people's different versions of the software available for our phone either officially or in jellybean's case unofficially.

"Rooted" just means the user (you) have the ability to make changes to the system or root of the device that are not possible for stock non-rooted users. Just rooting your device means you gained administrator access to the system but nothing is changed until you install roms or other mods.
There is a truly great post in the development section by DroidStyle that details EVERYTHING you need to ask as a beginner. Here:

Ah, I see, I thought it was JB since there were reports of people in some countries getting the JB update today. Coincidental timing!
Anyways, I went through with the update but it failed.

Ah I see, so if I were to download something that's JB, it's just someone's "fan" version of it? And the JB version that leaked to the international phones today won't work on our Verizon ones?

My pleasure, no worries! I have to much respect for any dev who undertakes developing or porting roms to call it a fan version. It's best to refer to it as "customized" which is what they are: custom versions of what may or may not be available.
Nah, unless there is a leak for the Verizon Jellybean update consider any news you hear/see about GSIII updates as completely useless unless Verizon is mentioned. The international version has completely different hardware inside the phone so any roms meant for that device will not work in the USA GSIII. You also can't actively flash another carrier's roms for this phone, it's not suggested and has the potential to render your device unresponsive.

Yes the hardware is the same so go ahead and brick your phone. You fail to comprehend the fact the ROM has to be ported for us cellular for it to actually work.

Sorry I didn't get what u mean
I want flash a Verizon ROM onto the US Cellular Galaxy S3 , Is it will working coz it same hardware
The fact it is the same hardware doesn't change the fact that you have to alter the software/ROM to work on another carrier. That is where porting comes in and lucky for you there are some ROMs here that are multiple carrier ROMs .
I am going to try this rom Galaxy S3 Verizon (I535VRBLK3) for my phone
You are still not getting it. It will not work it is meant for those with Verizon as their cell phone carrier. Plus it is stock version not a ported custom ROM meaning it isn't altered and made to work on another carrier. Let me put it in caps "DON't FLASH IT AS IT WILL BRICK YOUR PHONE" I hope you got that. See you are on US Cellular and must flash ROMs for that carrier so you can't flash the ROM you want to flash but that same ROM I can flash because I HAVE VERIZON so i won't f**k up my phone.

In all 3 of my posts I stated that it won't work and why it won't work and yet you are still asking the same question. Either you are trolling the site or you are really are lacking intelligence as I stated that it won't work and it doesn't help that your posts make you sound like English is your second language. If you are using it outside the US then a different ROM won't help you but unlocking the SIM card can.

Yeah, you posted 4 different times in 4 different ways he shouldn't flash the VZW ROM, and he still wasn't getting it. So I spelled it out as plain and simple as possible. I figured like you did he is either trolling or English is a second language, or not even a second language. I also figured with as many times as you responded, you might actually bypass the bottle of scotch and go straight to hitting yourself over the head with a hammer
Sorry to make u angry
I just looking for way to use my phone
Because I can use Verizon for GSM in my country but US Cellular I can't
I was thinking like that because both of them has same hardware
Sorry again
My pet peeve is having to repeat myself which makes me angry despite being a mellow person. I just got through blowing the heads of zombies in Dead Island so I am back to being mellow. You will have to SIM unlock your phone if you're going overseas and insert a Verizon SIM card onto your phone.
Im gonna try to tackle this in a certain way:
There is a thing in mobile phones called firmware. It is like a combo of hardware and software. One thing it allows is software updates to how the hardware works. You know how you can update your bios on your desktop computer? This is a firmware update.
The firmware on US Cellular and Verizon versions of our phone are different. When you flash a verizon rom to your phone, it writes information to the firmware in a way that verizon phones are designed to work with. The US cellular firmware is different, so flashing a verizon rom on your phone will corrupt the firmware and make your phone dead.
Basically, even though the hardware is the same, the part that updates the code within the hardware is different, and verizon roms are not compatible with us cellular roms for this reason.
You can only flash roms designed specifically for US cellular phones. Some roms on the forum have the tag D2USC. These roms will work with your phone.

I will also add that ROMs that are multi-carrier compatible are compatible with US Cellular just make sure you choose your current carrier.
Thanks sfetaz for elucidation
So is there any ROM Supports GSM & CDMA as ROM Verizon , Can I use it with US Cellular
Just go into the development section and download Axis. Make sure that you root your phone, unlock your bootloader, make a nandroid of your current image, back up your IMEI, and choose US Cellular in the options screen for carrier. You will then have flashed a custom ROM to your phone.
READ everything about all of the steps and UNDERSTAND what you are doing before you start or you will brick your phone!

Okay, just happened across this line of interesting conversation. But, I do have a question. Is there any way to change a phones firmware to allow it to expect another carriers ROM or is that simply a pipe dream?

Darkhlmt I'm not sure what you're looking for, but I know people with the Canadian variants can edit their build prop to accept d2att ROMs, but they share model numbers (Canadians add an m at the end)
APAs, there are a few ROMs compatible between vzw and USC and I mean few. You're better off hitting the forums at teamuscellular.com for your device, rather than risking bricking your phone

[Q] Noob Question re: what rom to flash

Hi All,
Newbie here, I have a samsung s4 that has been rooted and CMW installed and I'd like to flash it back to stock. The phone was originally locked to virgin mobile Canada but I paid to get it unlocked. Do I need a ROM specific to virgin mobile to flash back to stock or will any one do as long as it's for the S4? for example I've seen ones that are for at&t, rogers, bell, etc... does it make any difference?
Reason I want to flash back to rom is to be able to get the OTA updates again and be able to upgrade to lolipop when it comes out. In fact, is there a way to re-activate OTA with out having to reflash?
thanks in advance, keep up the excellent work!

I think you are talking about unrooting.To do this you have to go to SuperSu and settings(whatever it is called).There is an option called "permanent unroot" this should takeaway your root access

Hi Kobro,
Does it matter what type of ROM I use? My phone is an s4 originally locked to Virgin Mobile Canada, does this mean I need to find specifically a Virgin Mobile Canada ROM for my s4 or will any stock ROM do as long as it's for s4? (I haven't been able to find a Virgin Mobile Canada stock ROM anywhere for the s4)
Thanks in advance!

any s4 stock rom should do the trick
however, you should try sammobile.com to seeif they have the carrier specific firmware.
After flashin with odin i suggest to use kies to control the latest version.
Thanks everyone for your helpful replies. I might wait till Lolipop is officially released for s4 before I flash back to stock. S4 Lolipop here I come!
