[Q] Question about Kernal/Radio use and roms together - Samsung Galaxy Nexus

When flashing a rom, are all the kernals and radios that are in the GSM section (that is what my phone is) usable interchangeably with each other? I wanted to make sure about this before I go ahead and do it and then find out the answer is a no and then have a broken phone.

You can pretty much flash anything to anything(roms,kernels,baseband). Different roms with radios and kernels etc... Some will result in good performance, some will result in bad performance. Its always good to try and find a good combo that works best for you. Whatever you do just make a backup of your primary rom in case you dont like what you did and you can easily revert back. Something that may help you better is reading people signatures. I have tried different combos and im still testing as i go along because new updates of everything comes frequent here. Just give some things a try. You will be suprised.
Also have you rooted and unlocked your bootloader etc?

Which ROM?

I have just recived my phone, currenly has WM6 on it. The phone is uinlocked, and CID unlocked, I have been reading for a while but there are just so many different ROMs to choose from that I would like an opinion regarding that ROM i should use.
Also is there a way to back up the current ROM i have just in case?
Finally what Radio ROM should I use? I live in Miami Florida and use Cingular as my provider. Again there are just so many different versions I would like the imput from experienced users to suggest what might suite best.
In the end it all comes down to what rom you find is best. I hear Schaps' roms are good (theres a few...million) and for your first i'd advise a full ROM.
I prefer a lite ROM, where most all programs are taken out so i can put in what i like, but u should play around with a full one to see what apps u like/dislike first.
As for backing up a ROM, u can backup everything IN a ROM with spb backup (just use the trial), but if say you didnt like another ROM and wanted to go back, you would have to reflash the ROM you have the backup for then restore all the settings, files, etc.
For radio, i always see 1.48 and 1.50 commonly referred to as the "best."
In the future tho, try using this to find what you need first There are a number of "best rom"/"best radio" threads floating around.
Good luck and flash safe

A little confused about radios...

Surely by the title you can tell I am a noob. I would like to flash my first cooked rom but I have a question before I get started. I've been doing a LOT a reading to make sure I get this right the first time, however I haven't found anything that specifically helps me concerning radios.
How do I know which one to choose? Do I just automatically use the one specified by the chef, even if it is for a different region? I really don't know how to go about choosing the correct radio, if it is chosen by where I am, or where I go? Or what Rom I choose, or what network I am on? Does any of this even matter or do I just go along with the specified radio????? Do I have to flash a radio for the phone to even work or does the stock one remain? Any help is appreciated guys, thanks.

You'll just have to experiment to get the best result. Flashing ROMs requires a lot of time and testing. Some ROMs will come with a radio suggested and some won't. Just stick with your currentl readio and see how well it works. If you're having problems after a few days, try a different radio.
As far as ROMs go, you just need to know what kind of phone you have: CDMA or GSM. Don't mix them and you'll be fine.

The simple-and-true answer about "which radio" is that there really doesn't seem to be a "best-radio-for-ATT" or "best-for-northern-california" or "best-for-Valky-roms". Have you seen/read the GSM Radio sticky thread in the ROM Development sub-forum?
That being said, you might try 4.49.25.91 and/or 4.49.25.77 -- both very popular.
Just like flashing a custom OS-rom, you need to run the Hard-spl first. If you haven't yet, read "Flashing Your first GSM rhodium rom" on the Touch Pro2, Tilt 2 Windows Mobile ROM Development forum.
If you have a Sprint or Verizon phone then you need to read/flash stuff on the CDMA subforum.
Ok. Just a game of trial and error, I see. I'm working on downloading everything and learning how to do this precisely to not mess up! Thanks for the info!!!

EVO Rom question.

So I don't have an EVO, but I have a friend that does and will pay me to jailbreak it for him, so I was wondering:
Is there a ROM for the EVO that will keep all the stock OS components exactly the same and look and feel exactly the same, but will increase battery life and maybe tweak some speed and internet properties?
Thanks in advance.

Look into Sprint Lover's Rom....it is the same as stock except with some enhancements. All stock stuff is included. Never used it so don't know about speed but can find info in the development thread.
Otherwise, you could just root it and keep it as is afterwards. Would be exactly the same as stock except rooted and then the user could tweak it over time.
Honestly, all Sense based roms can be made to look exactly like stock but with extra enhancements and speed. A lot of developers will even provide a directory of stock apps taken out so they can be re-installed if someone wants to use them.
Yeah, but even I am new to ROMs and wouldn't have a clue where to begin with that level of custimization.
I think your best bet is to root (obviously) then flash a well-known Sense ROM, like Sprint Lover's. A lot of even the Sense ROMs are starting to customize and theme right out of the box, so it's harder to find a well-supported ROM that still looks stock, but I think Sprint Lover's is the one to beat right now.
After that, you may want to look into a kernel upgrade (a kernel comes as a zip that flashes in recovery just like a ROM, just make sure it's a Sense-compatible kernel). Probably Netarchy's 4.1.9.1 or something like that. I really suggest you read up on the debate over SBC kernels before you decide to use one of those, if you were ever thinking along those lines.
After you root, the first thing you should do (and before every flash) is to make a NANDROID BACKUP!!! Either ClockworkMod or Amon-RA will let you do that easily.
What's a Kernel upgrade? If Sprint Lover's really is the same look and feel with some tweaks to speed and battery, will I even need it?

Kernels are what happens behind the scenes in a rom. Calculations, battery compensation, CPU governors etc etc.
stock roms have kernels from HTC, which are actually known here to have pretty good battery life.
In addition to flashing a custom rom, adding a custom kernel may give more of an edge to what your friend needs.
Kernels here will range from great stability, great performance, or great battery life.
A good rule of thumb is that a good rom will only offer two out of the three, those that claim all generally are just assuming.
That being said there is no definite, uniform "best" combination as hardware/conditions will always be different. Flash a combo and see which works best for your buddy. If he spends a lot of time at the office and at home, performance is best. If he's on the road a lot, perhaps battery fixations will be better.
If he doesn't need much but needs to be able to make that call or text in a clinch regardless of conditions, he'll need stability.
The process seems intimidating coming from iPhone modification, but it can be fun and at times addicting to see what combo best suits you.
If you need something stock with upgraded tweaks, I recommend mikfroyo *4.2* or sprint lovers. As for a kernel, you're looking for Ziggy work. Netarchy is arguably one of the best, but you'll have to sift through a lot of version numbers to get one right, some are potentially dangerous to your specific device so I suggest you read up before downloading.

Is that so? So are there Kernels that can be applied to the stock ROM? That'd be the best case-scenario. He doesn't want his phone to look any different, but he'd favor battery life and performance over stability. Any Kernels come to mind, then?

You are going to have to flash a custom ROM before trying kernels anyway.
Start HERE.
It is on a different forum but it is instruction from this forum with pictures.
It includes an installation of sprint lovers, which is faster, and your friend will have more control over the system, such as removing bloatware, or wireless tether. Then he can easily try flashing kernels after that.

Please be aware that this process although the easiest and straightforward, it involves the process of flashing radios...
Under NO circumstances are you to turn off the phone or remove the battery during the img flash or your phone will brick.

That's seriously the easiest way to get Sprint Lover's? Looks incredibly complicated. All I had to do on my Droid X was install z4root, bootstrap recovery. Root my phone, make a backup, and install the rom from zip on SD card. Can't do that with the EVO?
it is not complicated.
<http://htcevorooting.x10.mx/wiki/index.php?title=How_to_root_your_current_EVO_4G_with_Unrevoked3>
Used unrEVOked3 software to root and unlock NAND (s-off). It is one of the cleanest and easiest rooting programs you could imagine.
Before you do this you will need to install HTC sync software from HTC's website, then uninstall ONLY the sync software portion, and leave the driver portion alone. You also need to install a modified hboot driver as well, as outlined in the link above.
After that, to flash a different ROM all you need to do is put it on your SD card and boot to recovery by turning the phone off, and then turning it back on while holding the volume down button. You can easily find the command to flash a new zip file within recovery.
And if you want to make things even easier, download (and I recommend purchasing) Rom Manager from the market, after you root.
Also, here is a ROM that might interest you. Called stock turbo.
<http://forum.xda-developers.com/showthread.php?t=864501>
I must make something clear about that ROM. The second post in that thread says that you should use a different recovery software than what is used with unrEVOked3. Although, I have successfully loaded this rom with clockworkmod in the past.
That ROM looks like exactly what I need. I have a couple questions, though:
What do I need to do before installing that ROM? I know I need to root the EVO. Is that as easy as getting z4root on the SDcard and installing?
Also, the dude recommends using Amon Ra 1.8 to back the phone up. How do I get that? SDcard install or something more complicated?

First timer; please double check my learning.

I've spent some time on another area in this forum, as an owner of an HTC Touch Pro 2, running WinMo and booting into Andriod from there. On that side of the world all I had to figure out was if I wanted a cab installer or a rar'd installation, and how to work up a startup.txt file.
Quite the different ball game over here.
My new phone comes in the mail tomorrow and I've spent the last few days digging through this place, google, wikis, all over trying to absorb some of this info. Here's what I think I know so far, I would appreciate your knowledge and tell me if I'm on the right track.
1. First I will want to root my phone with unrevoked3, then do a nandroid backup, which I believe is like a backup image of my current setup that I can fall back to if I have issues.
2. Next I would do an unrevokedForever which is like a full and permanent root, and sets my phone to S-OFF to allow for potentially disastrous things to happen.
3. Third step is I may or may not want to update the radio, which may make connections, call quality, and download speeds better or may make them worse.
[Q] - Do some roms require a certain version of radio firmware?
4. Radio updated or not, I would choose which rom I want to run. Lots of choices, seems like a few good standouts for a new user to learn the ropes with.
5. With a rom loaded, I may or may not want to update the kernel to something other than what was released with the rom package.
[Q] - From what I read, it looks like people run kernels from different developers, not necessarily from the dev(s) of the full rom, correct?
I hope I'm off to a good start. Any tips you can send my way is much appreciated.
Sounds good to me. You got the steps down.
And yea kernels are usually not by the rom dev. Just make sure your using a sense rom with a sense kernel or aosp rom with aosp kernel.

Correct - PRE-ROOT - you may want to make a complete copy of your SD card on your PC first, and ensure you have ample room on the SD. Further, you should verify your contacts are synched to Google, not saved as phone contacts. Absent that, back them up to the SD before copying SD contents to PC - then they'll be on device and PC.
2. Next I would do an unrevokedForever which is like a full and permanent root, and sets my phone to S-OFF to allow for potentially disastrous things to happen.
Not correct - the current version of UnrEVOked does S-OFF for you - users have no choice in this.
3. Third step is I may or may not want to update the radio, which may make connections, call quality, and download speeds better or may make them worse.
Recommend you wait on this to see how your newly rooted device does with different ROMs, then read all you can find about radios, then consider whether you like what you have, or consider a different radio.
[Q] - Do some roms require a certain version of radio firmware?
Radio requirements, if any, should be stated in the ROM specifications/features listing - required radio upgrades are few/far between
4. Radio updated or not, I would choose which rom I want to run. Lots of choices, seems like a few good standouts for a new user to learn the ropes with.
5. With a rom loaded, I may or may not want to update the kernel to something other than what was released with the rom package.
[Q] - From what I read, it looks like people run kernels from different developers, not necessarily from the dev(s) of the full rom, correct?
Recommend reading up on kernels. Note that there are 2 types of ROMs - Sense and AOSP - only Sense kernels run on Sense ROMs and vice-versa. Kernels are a personal preference depending on whether you want battery life, speed, etc. etc. They vary, so reading up on this will benefit you.
I hope I'm off to a good start. Any tips you can send my way is much appreciated.

Recommend backing up the SD card to the PC every 6 weeks or whatever frequency seems right to you. Why? SD cards fail, and when they do, you have a quasi-recent backup of your card.

[Q] Just trying to understand this

OK....So im not new to XDA or android really....have been in the HTC Hero forum for a little bit, but my new phone will be here tomorrow....
So far things seem just a lil bit different on this side, please correct me if im wrong....
Kernels-cooked into the ROM cant be flashed over with a different kernel?
Root looks pretty easy to achieve, but also easy to loose/unroot?
CWM doesnt play well with this phone, and must be cooked into a ROM instead of being flashed freely?
Modem/Radio...is there a new or old better or worse...are these all just cooked up and are trial an error? It seems that there should be some kind of consensus as to which ones are good,bad,or indifferent...or which ones work better in a different markets?
And the xx14 or pgxx....different codes for ROMs, what is all of that about, a little insight into that would be GREAT!!
Again, I have been reading over the forums for a week or so now and I am just trying to wrap my head around how this new process is going to work...The Hero is a legacy device and everything seems second nature for me. Alot of people in that forum moved on the the Evo3D, but I was ready for a something new and different, so here I am! I just dont want to screw something up on this device.
Thanks in advance for any positive input.
Edit: OOPS....Guess this should have gone in the Q/A...sorry.
For the code names like FC14... is basically identification of the build date of the ROM.
F = year (2012)
C = month (March)
14 = day
Gotcha, thanks!
Recovery is packed with the kernel. You can use any kernel you want as long as you are using gingerbread kernels with gb roms and ics kernels with ics roms. You can flash them with odin or cwm.
There are currently issues with ICS kernels so it is not recommended to use recovery on any ics kernels.
Modems are basically trial and error with regards to which is best for your phone. You are free to use any modem on any build.
The absolute safest route is ODIN for sure. There is a lot of speculation on what exactly is causing bricks. It seems the worst of it is connected with ICS and Clockword Mod Touch Recovery being used together.
Odin is a very nice tool that you can use from your computer to flash rom files, kernels, and modems. There is also Mobile Odin available from the play market for a few dollars. It's a worthwhile investment because you can flash tar files without a computer. But it is a known issue that the modem won't flash, which isn't a huge deal. Just do it from your computer when you get a chance.
Root isn't necessarily easy to lose. The only way to lose it is to personally remove root using a tool, like autoroot, or to do an OTA update from a stock rooted ROM, that would also remove root. Other than that once you're rooted you are good to go.
Be sure to do AS MUCH READING AS POSSIBLE. People are BRICKING their phones. They are breaking them beyond personal repair, and Spring Tech repair, thus needed warranty replacements. READ READ READ READ READ READ. I can't say it enough, nobody can say it enough. Even the developers have bricked their phones.
Yeah, I am reading...lol
Thats what made me post this because some of it doesnt make sense compared to what I am used to...
I am pretty sure im gonna root and stay stock for at least.....a day! Just to get a feel for it, and be able to tell a difference between stock and Mod... But I must confess I am a flash-whore and have been dying for some ICS goodness!!
I came from the EVO 4G; here are some things I've picked up.
1) The recovery and kernel is combined with samsung phones (same partition). So you can't just flash 1 or the other, you install both.
2) Touch CMW on E4GT is unproven. Some fared ok, some say otherwise. To be safe, I'd avoid it for now. Regular CMW and Rogue recovery are pretty much the gold standard here.
3) Any recovery installed by Rom Manager is temporary (again kernel/recovery are combined). Meaning it won't stick past a normal reboot.
4) Until ICS source is released, any actions done specifically in the ICS kernel-based recovery could potentially brick your phone. This is especially true for any ICS aosp roms (CM9, miui v4, aokp, etc). So this means once you flash from gb to ICS, your recovery is suspect. I will say that I don't see many reports of people bricking with these TW ics leaks, as many just seem to use calk's format all script and flash away. To be 100% safe, its best to odin back to a gb kernel-recovery to anything within the recovery.
5) Learn to use Odin; its important to know if you are going to play with ICS right now.
Good luck!
modems, just like radios, are going to be different for each user.
personally i just use the latest modem since sprint sucks no matter which one i use.
root is achieved simply by using odin to flash a rooted rom.
unroot by simply using odin to flash a stock rom.
very easy!
