custom rom and kernals, should one install them? - ONE Q&A, Help & Troubleshooting

I recently ordered the OPO and I was wondering if there was any point to installing a rom and a kernal.
Are there any important/good/large beneficial features and stuff to installing them?
Is it recommended to install one?
I'm just trying to decide whether or not to install rom/kernal before I get the phone so when I get it, I can work on it right away.

The phone works great out of the box, although it has some bugs.
So you install custom ROMs and/or kernels if you want to get the bugs fixed (e.g. the battery drain), you have a ROM you like for other devices you had (e.g. Paranoid), or you just like the idea of flashing something every couple of weeks, when the ROM is updated...

I have to disagree with your first statement. I've had no bugs or battery drain with stock CM11s except for 30O which is now obsolete. Custom ROMs are for different feature sets and those who like to tinker

Nobody can answer this question for you. There are points to installing custom ROMs and kernels, and each user has their own reasons for doing so. Only you can decide whether CM11S is a good fit for you, if not then try custom ROMs. It all depends on what you want to get out of your phone.

[Q] Planning to root and put a custom rom on a friends phone

Hi there, my friend is coming round soon and I was planning to give it a custom rom
Now, I've done this type of stuff before (on my nexus) I just want to see how you would do it for this samsung phone
Now, what recoveries can you get? I use 4EXT on mine
And, can anybody send me to a stable and up-to-date rom that can be used everyday and has nearly no issues? I need one without all the samsung stuff, just a normal default android one
And, how would I go by rooting the phone?
On mine, I used the zergrush exploit, does it work for this phone??
If you want one with everything working, then use the Froyo roms. CM7 is under development. The major bugs are bluetooth and youtube hq. Leaving that, even thats useable. It's even better than Froyo.
I suggest you to try either Kyorarom or Kyrillos v9.6. Both of them are froyo based, pre-rooted, and have other mods to make it even more faster than a stock one.
Happy flashing!

Thanks, and how do I go about flashing the rom, would I have to root it first?
No need.
This is something to good to read http://forum.xda-developers.com/showthread.php?t=1372414
BTW to root the phone use super one click root (or sth like that )
Ah, I get it now, thanks
Just one more question, does ODIN delete the phones data before installing the rom?
You have to wipe all your data after flashing(or not if from Froyo to Froyo)
I mean from recovery. ODIN don't delete user data
I exactly I don't know the working of odin, but after flashing you are directly taken to the recovery and advised to wipe data and factory reset.

[Q] Clean Rom

Hello everyone,
What exactly does Clean Rom do? How is it different from what comes with the phone stock? Will Clean Rom mess with the updates that are pushed to our phones? Any big differences between layout?
Sorry for all the questions. I'm just not familiar with modifying my phone.
Must read more. Spend as much time as you can reading in the dev section. Clean ROM removes all of the ATT bloat and adds functionality like the FM radio and remapping the 3 dot menu button that takes up screen real-estate to the recent apps softkey. The recent apps can be accessed by holding down the home button, like we're familiar with. It also has performance and battery tweaks (says so in the changelog, haven't been using it long enough to notice). I flashed it the day before yesterday and I'm liking it.

Clean Rom doesn't use profane language, think of it as the Will Smith of Roms...

Did you bother to go to the Development forum, and read the CleanROM threads? They very well describe the features of each version of CleanROM.
You don't ever want to install an OTA update once on a custom ROM. It won't be compatible. Either it won't install, or it will remove root, or it will totally bork the system. The devs typically keep their ROM updated to the newest firmware base, and often long before the OTAs go out. So there is virtually never a benefit to updating via OTA (even if it did work).
Most custom ROMs prevent you from even getting an update pushed in the first place. Kind of a non-issue there.
To the OP, if you want to flash custom, just do it. Spend a few days on Clean, try out Smokin's ROM, too. Just find something you like. Worst that can happen is you RUU back to stock.

Depends on the device, and I believe the carrier (and maybe the custom ROM as you mentioned). I've gotten OTA notification, and even able to download OTA (didn't install it, just to see if it would actually download . . . some have said custom ROMs will prevent that too) on 2 previous HTC devices on custom ROMs. But one was a Canada Bell phone used on AT&T, and the other was the WiFi-only Flyer tablet. So it may be that AT&T somehow directly blocks OTA to rooted phones.

I don't think att can see your on a custom ROM, it has to do with if the developer is able to include that ability or not.
Thank you for the replies!
I'm trying my best to understand how Clean Rom works. Is it the same thing as rooting a phone? Any disadvantages of using Clean Rom?
I'm just curious about how it works because I tried jailbreaking my iPhone and that made it very crash prone. It's a bad example but it's the reason why I never tried using custom software again but I'm interested in giving this a try. I only get about 2 hours screen time and about 12 hours of screen off time for my phone to die.
I did the HTC battery test and my phone went down to 92% so I'm pretty sure it's not the battery that's wrong with the phone.

It appears you need to do more reading to get a better understanding or root, ROMs, etc.
Root is just a change of permissions on your phone. It allows the user and apps access to system files that are normally restricted. Nothing more, nothing less.
Clean ROM (or installation of any custom ROM) is a total replacement of the firmware or operating system of the phone (also called a "ROM"). Clean ROM in particular is mostly based on the latest stock firmware version, but cleaned up to remove bloat, optimizations to make it faster and smoother, and some cool added features. There are 3 different versions of CleanROM. Just read the threads for each version to learn the differences.
I don't really keep up with iPhone stuff. But my understanding is that jailbreaking adds functionality, but makes the system less stable.
Whether a custom ROM on Android makes the phone more or less stable depends on the ROM. Some are ported from other phones, to give new UI look or functions, but can be a bit buggy at first. But any good ROM will be stable once it reaches "maturity" and the bugs are worked out. They can be very stable, and even more stable and smoother than the stock ROM. Which is one of the points of running a custom ROM.
CleanROM in particular is based on stock firmware, just cleaned up. So its very stable. Just as stable as stock, a bit smoother in some places, and with some awesome added features. Any disadvantages? Not really. But you need to unlock the bootloader to install any custom ROM, which voids the warranty. nd flashing anything to the phone has the risk of damage if you don't follow the instructions properly. Thats the only downsides I can think of (for any custom ROM, not just for CleanROM).
Redpoint had an excellent summary.
If you're looking for battery life improvement, there are significant advantages to a custom ROM. Some will allow you to adjust the clock rate for the processors. So you can turn the up a bit (overclock) to get incredible performance, or you can turn them down a bit (underclock) to get better battery life.
If that's your main goal, I personally suggest Sick Sense from Smokingl337. He has incorporated this into his ROM, and the reports I've seen have been positive. I had used his ROM before, and I did like it. The day I flashed CleanROM due to a minor bug, Smokinl337 updated his ROM to fix that bug. Figures! But I'll be going back to Sick Sense pretty soon, I'm sure.
Hopefully you can find something that works for you.

Different kernel or different radio may also help battery life.
But you need to root, SuperCID, and unlock bootloader to do any of these things (including flashing custom ROMs). So head over to Development and start reading:

There is also a clean rom developers edition that takes out most of the HTC sense... there is the cm9 alpha 4 rom that seems very stable...

OP, I was in your shoes last week. New to android/roms etc. I rooted, unlocked the bootloader and flashed Clean Rom. Just follow the instructions in the associated threads and you'll be fine.

[Q] "Flash and forget" ROM

Hi,
After flashing a few ROM/Kernel combinations on my dad's I9023, eventually running into problems every time, we're now tired of having to attend to the phone and just need something stable and self-sustaining, but still better than the stock offering, if possible. Reliability is the main concern, followed by performance, followed by features and easy upgradability to the next Android version (or the custom ROM's equivalent), but battery life is low priority.
Thanks in advance for any suggestion.
knzo strawberry

The closer to stock, the safer.
Strawberry is a good candidate.
Thanks for your replies. So far, Strawberry does look like the best option. Questions:
1. Does it keep up with Android updates?
2. Once it's flashed, will updating it to the latest version require wiping user data every time?
3. Which kernel should I use with it?

1. Your question is strange. Does it get updated? Yes. Keep up with Android updates? As in cross version (GB/ICS/JB)? Probably won't. But that doesn't mean crap, because CM7/9/10 are all different and flashing from one to the other without wiping is just bad omen. So in the end, it doesn't matter if your favorite ROM moves from one version of Android to the other. You want something new? Find a new ROM. There's only very few roms that went from ICS to JB without notable changes and none as far as I'm aware that went from GB to ICS to JB.
If you mean incremental updates (say, Jellybean gets updated) then yes, most ROM cookers update their roms.
2. No
3. Included kernel
I did mean incremental updates, thanks.

Alright. Then yes, most roms available here are update incrementally by their developpers. Usually popularity brings constant updates, too.
You want true "flash and forget" for your dad, Flash factory from Google. If your Dad doesn't care if it is custom or stock, just flash factory and move on. All custom Rom's and kernels come with issues. Google's bugs are solved by Google and send the update via OTA so Dad can do it himself.

Flash RasBeanjelly and trinity or bedalus kernel (check for stable one) and forget all about it as it is incredibly stable!

[Q] Phone application force closes after finishing a call...

Hello, all.
I have a T-Mobile Blaze 4G with rooted stock ROM (Gingerbread), flashed radio version T989UVMC6, manually debloated and dewizzed. I'm running Halo launcher and Busybox Free version 9.6.
Since almost the first day I've had this phone, it would occasionally force close the phone process, usually when hanging up the phone with the Bluetooth radio on and paired with an earpiece. It happened bone stock, rooted, after I changed the modem, whenever. It seemed to happen less often after I changed the modem. The process always starts back up, but the Bluetooth device connection and system sound controls are wonky (unusable) until the phone is rebooted.
The only thing that seems to stop it is running Zepplinrox's V6 Supercharger script. That, however, occasionally freezes the entire system when trying to open certain apps, requiring a reboot. I've run earch after search on this subject, and nobody else seems to have this problem. The only thing I haven't tried is wiping the whole thing and flashing a custom ICS or JB ROM. I tried Dark Knight ver. 8 and hated it pretty much instantly.
I have two questions. Number one; Will flashing a custom ROM fix this situation? I figure that this must be a problem with the crappy stock Samsung ROM. Number two; Which ROM is fully functional and stable? I'd really like to keep this phone dependable. I don't care about the latest and greatest funky cool features that are hit-or-miss at best. I just need dependable, fast and functional.
Since you have been having issues for a while, I would suggest starting fresh. With a few runs of black hole wipe from cwm. Add a run of the gremlin remover for extra cleanliness. Then a flash of the latest ICS rooted stock rom and kernel, for reliability.

I'll definitely go for the rooted version! Does it matter what order in which the ROM and the kernel are flashed? Also, I take it from the name of the download link that I'll have to go through the process of de-bloating this thing again. S'okay, I actually enjoy that part, but I don't want to screw it up since I've not messed with anything newer than GB. Is there a good guide somewhere on the forum for apps that can be dumped safely? I know there was one for GB stock root.
Thanks for the response.

A few more silly questions; Do I need GAPPS or is that just for CM? Aren't the CM 10 ICS nightlies fairly stable and relatively bug-free? I use CM7 on my Nook color and it's...okay... Just a few little annoying things pop up with that.

The stock roms don't require gapps, but like Wolf said the cm10 jb variants do.

Of course. I get a bit confused ever since people started talking about 10.1.
Okay, I went ahead and installed the stock rooted ROM with the stock kernel. Went through the debloating process (mostly, there are some apps that I'm not sure I can do without so they stay for now), and did some customizing. I'm seeing a bit more battery drain. Is this an issue with ICS or do I need to try another kernel or supercharge the phone? I also have this crazy issue with ROM Manager ver. 5.5.3.0. It tells me that there is an updated version of Clockworkmod Recovery, but it freezes when I try to flash from ROM Manager. Also, ROM Manager freezes when I try to reboot into Clockworkmod Recovery. Maybe I need to test a bit more before I mess with it any more.
**EDIT** Well, it looks as if my CWM recovery installation is corrupted. Can I reflash it without messing up my current ROM?

Since you have it setup, except for battery life. I would make a backup, then try a mod one at a time and see if any help. Also check the battery stats to see if anything of is seen. ICS will use more juice than GB, generally.
I would suggest Nos/direct injection, supercharger, or cross breeder. I would use one and see, then restore and try another.

All of the force close and freezing issues have vanished, the phone's battery lasts almost as long as it did on GB, it's WAY more user friendly, and the phone is as fast as it ever was.

How to figure out what is causing heat and battery usage (CPU and Battery usage)

Hello. I have the GS5. For over three months it overheats like hell. Why because I did the firmware update and it all started with this.
TL;DR: I need an app or program that shows detailed percentage of usage and temperatures of apps. It would be great if you can find a real-time monitoring one like on PCs. My phone is rooted so feel free to recommend any app that suit my needs.
It overheats so much that I can barely able to hold the phone because it slips through so easily from my hand (nope my hands are not dirty, I wash them with lots of soaps ).
I bought a case and it is still somewhat hard to hold the phone with one hand but the case surely helped. Can use it with two hands but was able to use with one hand without any problems so why should I accept this right?
The cpu is around 40 Celsius at idle to very low usage. The battery is around 28 Celsius at idle. The room temps is 26 Celsius.
After using my phone for about fifteen mins, the battery is going up to 36-38 Celsius. The cpu is around 50 Celsius. Not playing games at all, just surfing on the web and installing one to two apps from Android Market. Do you think it is normal or excessive? I fell the heat in my hands. It was not been like this before the firmware update.
Although I did all wipes and flash the whole rom from scratch (even ticked Nand Erase All), my problem still persists so I am out of ideas. Maybe I can buy a new battery and a charger but I would like to make sure that the problem is not causing by software. Thank you.

Despite only little information available, I assume the issue is kernel related. Had you e.g. overclocked and over-voltaged? Most likely not as you were on stock.
Your custom ROM certainly came with its own, new kernel. I suggest to monitor the overheating first as you just recently flashed the custom ROM. However, you can also play with the kernel settings (my current one has its own control-apk, or by using e.g. an apk called "Kernel Adiutor") to see what's best serves your requirements. If you're not happy with the custom ROM's kernel, you can flash a custom kernel but check compatibility first. And remember, when you're on a custom kernel every time you flash the custom ROM you'll have to re-flash the kernel.
Here's a real good guide regarding CPU governors, I/O schedulers and more:

So I think I should update kernel on this custom rom with a new one? Because the OP says that flash hispasian kernel after flashing his rom. I haven't do that yet, nor I have experience about it. I believe I have a custom rom with stock kernel right now. I don't think it is related to custom rom. It overheats like I was on stock rom. Could be kernel. Can kernel be updated through the firmware update? It may explain why it starts to overheating after that. No, I haven't overclocked and over-voltaged the cpu. Maybe it came overclocked or over-voltaged with this custom rom but it isn't described.

I suggest to surf your custom ROM's thread and to figure out, which kernels can go with this ROM and which are the experiences of other users with the respective kernel.
Firmware updates (I assume you mean now updates of your ROM) won't solve your problem because with the update comes its own kernel i.e. you need to flash afterwards the kernel you want again.
I always flash my custom kernel through recovery. As recovery, I personally recommend TWRP in its latest version (as you see in my signature block, I'm using TWRP v3.0.2). An in my opinion very good tool, to install (actually flash through your current recovery) TWRP is via an App (apk) called "Flashify".
After you've flash TWRP and rebooted, google how to flash a kernel or search XDA for my postings. I think I already describe somewhere how to do so.

I mentioned firmware updates because I was wondering if stock (Samsung) rom firmware update did break something in stock kernel. Is it possible? I'm %99 positive this happened after the latest firmware update. I mainly flashed this custom rom to get rid of overheating problem but the problem persists.
I just flashed HispAsian kernel, which the creator of this custom ROM recommended, through TWRP and works fine for now. But nothing's changed about overheating.

Look into the kernel settings as mentioned in post #4 (http://forum.xda-developers.com/showpost.php?p=67135599&postcount=4).
Before you change anything I suggest to educate yourself via the thread mentioned in that post, too.

I actually don't care about custom roms. As long as I can find a solution for stock roms I would return to them. Could you please give me your solution for stock roms?

It's always your decision and desire. I think everything said also applies to stock ROM. Check your kernel settings and manipulate to your needs. Some tools were mentioned before.

It is too complicated for me. If you could just point how to downlock the CPU's clock speed then I can try and see if it works to prevent overheating.
Also let's say I decide to return to stock rom. Will current kernel replace with stock one?

I'm not familiar with your phone (wasn't it a Samsung Galaxy S5) or your stock ROM (Lollipop?). I suggest that you address your questions in the GSG5 forum, where the gurus for your phone rest. Sorry for that.
Anyhow, I added two screenshots of the apk "Kernel Adiutor" (first two), and two of AGNi control, which came with my kernel. As you see both of them support manipulation of kernel settings.
IRT your last question: I'm convinced flashing stock ROM is also replacing current kernel. ...but as said: GSG5 forum.
