Hi all,
I tried searching around and googling and I have a pretty good idea of what kernals and ROMs are. I'm coming from a Droid X (locked bootloader) and just upgraded to a GN. I unlocked the bootloader, but as for everything else, this is all new to me. I'm looking for a solid guide(s)/sticky on ROMs/Kernals/Radios.
Questions seeking to be answered:
1) What are "radios?"
2) How is it that kernals from other phones can be used on completely different phones?
3) How do I save a nandroid on the GN? (I've only unlocked my bootloader)
4) Does the stock SBF from google contain everything I need to restore to stock (kernal, rom, radio, etc.)?
I want to make sure I cover all my bases before diving into all of this. Thanks!
1) What are "radios?"
Radio firmware, or Radio's are the software that drive the cellular radio's (connects to cell service, data/voice/etc)
2) How is it that kernals from other phones can be used on completely different phones?
They can't. Without modification. Certain drivers and components need to be changed/added/removed for it to work. It's much easier to recompile the AOSP kernel from source (for the GN) and modify it from there as kernel developers have been doing.
3) How do I save a nandroid on the GN? (I've only unlocked my bootloader)
Install Clockwork Mod Recovery, boot into it, and click backup.

4) Does the stock SBF from google contain everything I need to restore to stock (kernal, rom, radio, etc.)?
Not familiar with the term SBF, however yes. All files to return to stock are hosted by Google, and guides on how to do exactly that are present in the forums.

Hey guys,
I recently got a Galaxy Nexus, and wanted to play around with it. It's still on the 4.0.1 stock ROM (yakjuux build). Haven't made any tweaks to it beyond the basics (removed vibration, disabled data since I don't have a data plan, etc).
Basically, what are the benefits of flashing the 4.0.2 factory image (from Google, can't link it yet)? And how would I go about it? My guess is, I'll need to place the files on the phone, then flash it using flash-all.sh. Or would it be better to just pick a custom ROM and go with that instead of flashing the yakju build?
The benefits of straight yakju are that you should get updates first (faster than yakju** people anyways).
Custom ROMs offer more than stock but bring their own issues/tweaking. Go read every one of the 1000000 threads on "stock vs. custom ROM" (think there's one going on in Q&A right now, actually).
If you want to switch from yakjuux to yakju, follow this guide: http://forum.xda-developers.com/showpost.php?p=21113773&postcount=195
I personally used this one to flash my Canadian model to yakju and it works great. It uses your PC (or Mac) + fastboot to flash the items in order. Be sure to follow all of the steps and flash all of the items. In order to receive OTAs (if that's important to you) you need them to all be flashed. Changing one (like recovery or radio) will stop OTAs.
If you need more info, the guide is pulled from this thread: http://forum.xda-developers.com/showthread.php?t=1464881
Sweet, thanks. That worked great.
I did notice a weird thing after rooting where my phone remained awake constantly even with the screen turned off. Not sure if it fixed itself though. I'll check again to see if the problem persists.
edit: It seems to be fixed now. Awesome.
Hello everyone. I'm a recent android convert from iOS, and loving it.
I've rooted and gotten CWM onto my Telus GS3 and made a back-up of the stock samsung rom
I would like to try out some of the other roms and have been pouring over the threads. Unfortunately, i'm still confused about a few things and hoping someone can clarify or point me in the right direction:
Flashing a new rom seems easy enough. I'd like to try out CM10/aristodemos JB. What i'm confused about is the following:
1. according to this thread, i might run into issues w/ build.prop
http://forum.xda-developers.com/showthread.php?t=1915875
what is it? and do i need to be following what they say in that thread w/ all of the AT&T roms i try to flash?
2. do i need to be re-flashing my telus modem from the Modem List after i flash these roms?
I guess i just haven't found the one thread that summarizes for us Telus users, what we need to do Differently when flashing say the CM10 or any other of the AOSP roms?
Thanks! any help would be appreciated!
Hi! I've a Telus S III myself and ran into absolutely no problems rooting and reflashing it (with CM10) - no build.prop tinkering and no modem reflashing (third party ROM images normally don't include modems, and those that do will note this).
I rooted through flashing - with Odin - the rooted Telus image available over in the sticky in the dev forum, which also includes instructions for flashing a CWM (make sure it is new enough to avoid the error 7 described in the other thread).
Basically, there's nothing really Telus-specific unless you choose the pre-rooted image route for rooting, and that only applies to the root process.
Good luck, and enjoy your customising...
ahhh perfect, that's good to hear!
thanks!
Firstly, I am not new to flashing or searching on XDA! I have installed custom roms/recoveries on at least 10 different android devices and have been a member here for some time. I'd like to think that I have helped more people out than I've asked for help....
but my new (to me) Note 2 has me stumped!!!
I have recently traded in my much loved Note 1 (running a rock solid AOKP KIT KAT rom) for a SGHi1317m (I believe originally from Rogers). It was unlocked and I am able to get full LTE service from my carrier (Bell Mobility) after setting the APN.
I originally upgraded in order to get greater functionality out of my Gear 1 smartwatch (better battery life with BT 4.0, among other benefits)
24 hours in and I am dieing to get back to some form of KitKat! The question is How?
I have searched this forum and have come away with the impression that because of the different variations on this phone, Knox, differing bootloaders with differing recoveries, there are many ways to brick this phone!!
I have already found out that one cannot easily update the recovery via the simple solutions offered on the playstore for CWM or TWRP. I am familiar with ODIN and have multiple versions of it running on different laptops in my house ready to try. The question is which package will give me a recovery that will allow me to flash roms and persist through a reboot?
According to my phone info, I am on bootloader i317MVLUCMK5 ( a version I have not seen in any of the tutorials) My KNOX counter reads 0x0 but when I try to search for updates ( I am presently on stock android 4.3 rogers), it says that I will not receive any as my phone has been modified (i suspect it can tell that the phone is unlocked as I am using a Bell sim in a Rogers phone).
As I have no warranty, and don't really care if my Knox counter is tripped, I am hoping someone can help me get started in flashing this phone.
i think if you look in the cwm thread you'll find instructions. mostly everything i see is a soft brick meaning it just doesnt boot into rom. i suggest cwm as it seems more maintained than twrp, and twrp gave me issues.
download a stock modem because the international roms will overwrite your modem and you'll get no signal bars and need to reflash after a upgrade. check out the n7100 form, sub forum n7105 and look for roms there. this forum is really dead. i'm running international rom nc3 with my at&t mk6 modem. mj5 bootloader because its 4.3 but unlocked from downgrading.
i too didn't care about knox or warranty, but most of the good stock roms have it stripped. i can't find anything as good as 4.3 tw stock roms and the custom roms i've tried seem to have fc's and whatnot.
i also used devil kernel and got tons of fc's so i'm using the stock kernel for now. might try agni. but back on topic your best bet is to try and find cwm odin package for philz touch. really once you get past all the noobs here you find it works just like any other samsung. you can flash a recovery via odin, cf auto root, and you're done.
Hello,
I just bought my first Galaxy device (had a CDMA LG for a while, and I have a Nexus Tablet), and I am looking at how to get this new phone set up right. I bought my i747 retail, so I was unable to unlock it. However, now I'm struggling with finding the right method for upgrading, rooting, etc. I know nothing about knox or any of these Samsung intricacies. Could someone please give me a little guidance on how to go about getting to the OS and status that I'm looking for? This is what I've done so far:
Came unrooted with 4.1.2 stock rom
Unlocked using legit unlock code
Tried OTA updates, but none were available (must be because of unlock)
Rooted w/ ODIN using 4.1.1 file based of MrRobinson method. (http://forum.xda-developers.com/showthread.php?t=1739426)
Now I keep getting popups like process. ... .acore,media, etc. stopped.
I'm looking to ideally get a custom recovery (either CWM or TWRP, whichever is better) and either kitkat Touchwiz or possibly kitkat nexus stock (I read somewhere that it was possible). Also, i just bought it, and have the code still, so I don't mind deleting everything if needed. Regardless, I'd like the ability to get it back to pure stock with no flash counter (I have a manufacturer's warranty I want to use if need be).
Could someone please just give me a little guidance? I'm pretty capable with rooting, etc., so you'd only need to lead me to other threads, etc. that will take me where I want to go. Thank you very much.
Before flashing or doing anything else, confirm the bootloader on your phone. Download and install the Samsung Phone Info app from the playstore and post your bootloader.

Well, the bad news is I already flashed using MrRobinson's instructions, and now my phone is barely workable, as things like process.android.media and Touchwiz keep crashing. I was able to install the info app though, and my bootloader is listed as I747UCDLK3. Thanks again though, and let me know what else you need from me.
I recommend starting over by flashing the stock AT&T 4.1.1 firmware from sammobile. Once flashed, boot the phone and make sure your phone is sim unlocked. If it isn't sim unlocked, unlock it using the free method or your unlock code.
http://www.sammobile.com/firmwares/database/SGH-I747/
After sim unlocking, run OTA updates until you have the latest stock AT&T ROM on your phone. Upgrading the phone's bootloader and modem is the easiest way to do it for someone that is new to the phone and custom ROMs.

Thank you, but wouldn't OTA updates install Knox, which would basically void my warranty if I tried to flash anything after that? And, I've checked for OTA updates twice, once on 4.1.2 and on 4.1.1, and both times it said my software was up to date.
I spoke with StoneyJSG about my situation, and he suggested that I go to stock 4.1, root w/ saferoot, then flash a kitkat custom rom without Knox through TWRP. That way, I could use triangle away and flash stock unrooted if I needed to send it in.
Although, I'm not sure if I should do that, as I thought I read that you need to update the radio and bootloader first before you can install a custom kitkat rom from jelly bean, but I'm still not entirely sure how that works.
The most recent release of many custom ROMs will not work but you may not have a signal without an updated modem and you should not be running updated modems on an older bootloader. Doing this could brick your phone.
With a rooted system, OTA updates will not work.
Thank you again for helping walk me through the minutia around this phone.
I think I have a much better understanding of everything now. I read the following article on Knox (http://omegadroid.co/wanted-knox-void-warranty-0x1/) and with an understanding of that, I get now that there is no way to load any custom rom on 4.3 or higher without losing my warranty.
So, basically my options are to stay at 4.1 and flash whatever, using triangle away to erase my tracks. Or, I could update to 4.3, but only be able to use saferoot/towelroot, otherwise I'd trip the warranty void. But, if all I did use was towelroot (no custom recovery or rom), then I could just unroot the phone using the full unroot option in SuperSU and send it on in for service if needed, right?
Also, I did unroot my phone and did a factory reset, so it's back at 4.1.1 and unrooted. Yet, I still do not see any software updates available from Samsung. I even plugged it into Kies, and nothing (http://i.imgur.com/E0xPGpf.png). Does anyone know why this could be? Does it have something to do with my not having a carrier for the phone yet? I'm sorry for all the questions, but I do appreciate your help.

What is your cell service? If not AT&T, you will never get OTA.
Whether you get OTA can vary from carrier to carrier and phone to phone in my opinion.
I have a Rogers HTC One X that gets OTA updates from HTC even though I am on the Bell network.
I have a Bell S3 that is running on the Rogers network and it receives OTA updates from Bell even though it has a Rogers sim card in the phone.
I have a Telus Moto G running on the Bell network and it received the Telus KK OTA update while connected to the Bell network.

Well, I have an AT&T model which I unlocked and will be putting on Cricket at the end of the week (when my plan month is set to end). Right now there's no SIM in it, and I've been doing everything over wifi. I looked up whether the carrier had something to do with the OTAs, and I was told that Samsung sent the updates out, not AT&T, so I figured that the carrier info was irrelevant. I now wonder what my options are.
Can I manually flash 4.3 stock without tripping the knox warranty void?
Does Towelroot/Xposed framework trip the Knox void flag?
If I can update to 4.3/4.4 and root without tripping the knox flag, I might just manually update and just run towelroot and xposed to modify my OS the best I can until my warranty runs out.
If I can't root it at all once I'm on 4.3+, then I'll just sit on 4.1.1 for a few months until I can't stand it anymore and just void the warranty anyway.
Thanks again everyone. This whole knox/binary counter thing is not something I dealt with on my CDMA LG or Nexus, so I was totally in the dark about how it all worked. This is also my first GSM phone, so all those intricacies are new to me too. Once I know about manually flashing stock and running towelroot/xposed, I think I'll be in good shape.
Flashing the stock 4.3 ROM should not trip the counter as long as you do not need to install a custom recovery to flash it.
Apparently, the latest KK stock ROM cannot be rooted using Towelroot.
If you want a custom ROM, use one that will work with a 4.1.1 bootloader and modem. Once on 4.3 or higher, it's a little harder to recover from a soft brick.

Excellent. If I did flash stock, i would just use ODIN, then factory reset to wipe the caches. And that's good to know about the KK rom, as I would probably update straight to 4.4 if at all (I've read a lot of bad things about 4.3 on the S3), but not if it means I cannot root safely and cleanly.
I'll check out the custom roms for 4.1.1. I know that flashing the rom and/or a custom recovery will trip the binary counter, but I can just use triangle away to clean that up. Do you know if there is a list of custom 4.1.1/4.1.2 roms somewhere, or do I need to scour the older threads here?
Thank you very much audit13 (thanks to StoneyJSG and pre4speed as well). You have been immensely helpful and really brought me up to speed on everything surrounding S3 customization. Needless to say it's way more complicated than what I've dealt with from LG and Google/Asus. (I mean, i could root my nexus with a single click using Wugfresh's toolkit)
4.1.1 is the only complete stock ROM that AT&T released for flashing via Odin.
4.3 ROMS and higher were prepared by XDA members for flashing in either a custom recovery or Odin.

Oh, so what other way can you flash a stock rom, if not through ODIN or a custom recovery? Regardless, it seems as though I really should not dive into 4.3+ until I'm ready to concede that my warranty is over. There are just too many potential pitfalls and headaches.
On the lighter side, I've found a few 4.1.2 based custom roms that have some promise. I'm going to post them here in case anyone has opinions on them, or if someone else in my situation sees this thread and wants to go custom 4.1 too:

I was also torn when I got my s3 that was running 4.1.2. I downgraded to 4.1.1, sim unlocked the phone, used it on stock 4.1.2 for about a week to make sure everything was working, hardware wise, upgraded to stock 4.4.2, installed a custom recovery and a custom ROM. I wasn't too concerned about the warranty since I got the phone as a free upgrade and had no intention of using the s3 as my daily phone. I kept it as a backup until my niece needed and phone and then it went to her. It's been over a year and there are still no problems with the phone.
