[I9100G] flashing cynagonmod9 and kernel questions - General Questions and Answers

Hello, i´m a noob and im a little bit afraid of flashing, because i have bricked before my phone.
I my device is: SG2 I900G
CynagonMod 9(some nightly build in August)
Kernel: ICS LP7 - 5.5.0.4
Android: 4.0.4
1.) if i like to change from a installed nightly cynagonmod9 build to a rc or stabel version of cynagon9, what is to do for keeping my
datas and app configuration ?.
there are options in the Rom Pre-Installation
- delete Data and cache
- wipe dalvik cache.
what is needed to flash this downloaded rom?
what are the different between RC and stable builds?
2.) Other question:
What Is needed to flash from cynagon 9 to 10 ?
4.) if i like to change my kernel: ICS LP7 - 5.5.0.4
which one would you suggest me?

Hi there
I'm also a new member here but have done several flashes of my different phones.
1) Although I've never used it I would say that Titanium Backup will do what you want in preserving your data and configurations.
You should choose both of these options since you're completely changing ROM.
You'll need ClockworkMod.
RC stands for Release Candidates and is the stage before a Stable version.
2)With that ROM on your phone you should already have the tool for flashing a new ROM, ClockworkMod, installed in your phone.
4) Personally I'm running Siyah's Kernel and to me it made my SGS2 I9100 run smoother then ever.
You'll find it here: http://forum.xda-developers.com/showthread.php?t=1555259
You can find a perfect guide for your phone and flashing right here: http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S_II:_Full_Update_Guide

Good luck and happy flashing

thank you for your advices

You can always leave your data if you wish especially if you are moving from a nightly to an rc. Just wipe cache and dalvik cache and fix permissions. That should be fine. Then if you wish to backup all data you should use Titanium Backup. However you should keep in mind that if you move from CM9 to CM10, you won't be able to restore the applications back! But you can restore the data. First you install the application from the market and then use titanium backup to restore the data of the application.
Remember that you can only restore user applications/data not system ones. So if you have contacts stored on the phone you'll lose them. Even calendar events which are stored locally. You need to snyc the contacts, calendar with google. And with regards to sms there is an aplication that can backup your sms for you unless you are not using go sms or handcent which have a built in feature.
With regards to kernels, CM9 and CM10 kernels are best for battery life (that's what most people say) but they do not have a lot of options available. In my case I cannot suggest you any kernels because I have International SGS2.

[Q] Kernel questions

Hi,
I had a few questions about kernels...hope someone can help me in answering these...
I am thinking of trying out the Netarchy kernel on my Nexus S, but i was just wondering is there anywhere I can download the stock kernel (so that if anything does go wrong i dont have to do a full nandroid restore?)
Also, when installing a new kernel does that wipe data (of course I will make a backup etc before installing it, but should all my settings and apps etc remain intact normally?)
what impact does an OTA update have if i am running a non stock kernel? so say i am using Netarchy's kernel, and google releases a new OTA update...will i still be able to install the update? If i do, will it revert to stock kernel?
Thanks in advance,

I'm not aware of anywhere that the stock kernel is available for download so doing a NANDroid backup is really your best option. If you have anything that deviates from stock (kernel, rom, theme, even just deleted stock apps) it will prevent you from being able to successfully update from an OTA.
You can find a lot of information about all the available kernels here just scroll down to the third post and you'll find the info.
Finally, just as a note of personal opinion, getting OTA updates is a little overrated. If you run a custom ROM, the OTAs will be included in those ROMs eventually so you won't have to worry about restoring a stock ROM just to get the updates.

Thanks for the quick answer. I had read that post before (it was actually how i came to discover kernels ). The reason why I was asking about the OTA is because I actually use the stock ROM but was just thinking about trying out the Netarchy kernel just to see what its all about. Hence if there is an OTA update, and i am running a different kernel to the stock, is the only way for me to incorporate the update by flashing the new stock rom and then reinstall the netarchy kernel?
Also, if i install it, do you know if it wipes data/apps?
Thanks

I apologize as I forgot to mention that part of your question, I'm sick with the flu and a little out of it on some cold medications lol. You only lose data and apps when flashing if you wipe the /data partition in mounts and storage and this is not required nor is it recommended when flashing a kernel. Sorry for answering out of order, but I thought I should clear that up first. As to the other question, you have it correct; you would need to flash the new update ROM and then flashing a new kernel.
I should also note that whenever you install a new ROM, you will need to reflash a custom kernel. This is because the vast majority of ROMs released include a kernel and when you flash them it will overwrite whatever kernel you currently have.
Finally, if you have any other questions you can always feel free to post them on that thread. I'm the one who wrote it and I check it often to try and answer questions as best and as quickly as I can. Happy flashing!
Are you using a custom ROM? Flashing CM7 has the stock kernel. There are probably other ones out there that includes stock kernel with them such as OTA.

[Q] New to rooting; after flashing a custom ROM, what happens if I want to upgrade?

Thanks to everyone on this board - last night I rooted my device, unlocked the bootloader, installed CWM, backed up my stock ROM, and installed CleanROM 3 Lite (which is excellent btw!). My first time doing this, so it was very helpful having all the FAQs and instructions.
On to my question: now that I am running a custom ROM, what happens if there is a newer ROM released? Do I simply re-flash that specific ROM, the same way I installed CleanROM 3 Lite?
If so, it sounds like I lose all my apps/settings... is there some way to keep that across ROMs?
Thanks!

yes. And unless the developer says not to, you can USUALLY skip wiping /data when upgrading to the newer version of that developer's ROM.
As for keeping apps, get Titanium Backup. worth paying for.
If you are going to upgrade to the next cleanrom release, you should be fine...just flash the next release and your apps and info should be fine.
Should you choose to switch to another rom, it is typically recommended that you wipe the phone first, in which case you will lose your apps and info, so make sure everything is backed up.
The problem with keeping apps and settings across different roms is that there can be "compatibility" problems.
That makes a lot of sense, thank you guys. I thought that flashing a ROM automatically wiped everything - but I realize now that's not the case.
I will check out Titanium Backup as well.

Actually, sometimes it does. Recently some Devs are adding Aroma Installer to their ROMS. It only works on touch recoveries (I believe). I am using TWRP and it works great. It backs up your info, lets you choose different options you want for your rom (modifications, different choice of apps, look and feel, sense or senseless, etc), flashes the rom, then restores your info automatically.

I m confunsed now:(

So After some roms instaled on my lg there I chose GTR V6 (V7.8 DONT SEMS to work stuck at logo)
My question is about roms and kernels, so after I instaled GTR v6 on my phone I need/can to instal a kernel ? so If I can or need how I do Ive read a lot of threads but I dndt found a good answer so after I instaled a custom room How do I instal a kernel Is the same as rom? revocery then
wipe data/resetfactory and wipe chache and instal like a rom? Plz tell me how to do the right thing
I just want a good phone for a little gaming and like a normal phone
no.. just flash without wiping.

Step 1 - Boot to recovery
Step 2 - Back up (just incase)
Step 3 - Flash kernel of choice
(optional)Step 4 - Wipe 'cache' and 'Dalvik Cache'
Step 5 - Reboot
Step 6 - PROFIT!!!!
The cache, and dalvik wipe are optional to me. I always do it, and have better luck that way. Doesn't harm, just makes that next boot longer as it rebuilds those caches. I had an issue ONCE where I had to wipe cache, and just do it every time I flash a kernel now

Quick noob question: what is a new kernel good for ?
I already have AOKP 4.0.4 on my P500, but saw different talks about different kernels.
So, what is the kernel and what it does.
Wil flashing a new kernel affect other stuff (installed apps, settings...) ?

There are different kernels that people have worked on that are better for certain purposes. Consider the ROM a airplane, and the kernel the pilot. Different pilots are better at certain things, but all are certified to fly the plane
Things that our kernel devs have added are touch screen driver fixes (LGs were ****), undervolting and CPU frequencies additions for performance, VPN stuffs, ect ect. When you install a new kernel,it won't make you lose any data or settings. Everything will be just as it is for you.
Basically adding features and improving performance beyond what LG provides. Looks like Williams awesome looking AOKP is running the same kernel Hehap does on the version of ICS I am running and it is pretty good. I am testing DJnoxDs ICS kernal with touch screen fixes and vysnc off here http://forum.xda-developers.com/showthread.php?t=1587209 and it is pretty fantastic so far.
But if you wanted to try out different kernels with the ROM you areon, you can flash it over in recovery. If you do a backup in recovery before hand then you can easily go back to the kernel he provides.
Just make sure if you are having any issues with his ROM after that, to keep the fact you changed kernels in mind. Check the threads for the kernel you are trying if issues come up after flashing, or at least mention in William's thread that you are using a different kernel if issues are coming up so bug reporting happens correctly.
Got it, thank you very much for the infos.

Lifecycle of ROM's posted here - Alpha, Beta, offcial?

Hello,
I have a general noob question on the custom [ROM] threads.
Do custom ROM's posted go though an alpha, beta, official release stages? I see some [ROM] threads marked with an alpha or beta... while some others are not.
thanks!
U r right, alpha means something major is broken, beta its the "refinig" stage, and final its the complete rom

Is this process that is true for all ROMs that are posted? I see a few ROMs that don't say alpha or beta. Does it mean they are release grade?

There is no such thing as release grade. Everything should be considered at least developmental in some form or fashion.
The terms of alpha and beta do not mean what most people think they do in here.
Even the ones marked alpha and beta can still be daily drivers, just take a look at the first post of each ROM you are thinking about and see if the bugs will "bug" you like for instance any of the CM based ROMs here have issues with camera and video and few other small bugs.
Any ROM based off of "stock" will have less/no bugs and therefore not marked as beta or alpha, since they are not compiled.
It all depends on your personal needs as to what you are comfortable with and if you can deal with certain things not working right out of the box, or that you might have to make a work around for.
I call mine "alpha" or "beta" depending on bugs and/or how much more work I expect to put into it... and my mood at the time
Jim explained it well... it's all subjective to the dev and the end-user..
Best to just make a good backup, know how to restore it, and slap a new ROM on your phone to try it out for yourself.
That being said, be on the lookout for a gamma version of Numa ... (j/k - it's been a long time since I was back on ICS)

Regarding making a good back up, Should I just follow the CWM thread? I found this link in the newbie thread. However, there was little explanation on it's use.
http://forum.xda-developers.com/showpost.php?p=19355021&postcount=1
- Does using the CWM recovery to create a back up have any per-requisites? Can I use it on my stock AT&T Atrix2 that is still on GB?
- If I understand correct, this is used to dump an entire image of the phone (firmware, OS, apps, files etc...) to an SD card? And one can later restore back from.
- I am planing flashing the NUMA Rom. If I take a back up using CWM, I assume I can restore everything to they way it was (i.e. back to GB) without risks?
thanks

First, you need to get ICS on your phone if you want to flash Numa. You must be on 4.0.4 firmware to flash any of the ICS and/or JB based ROMs. The choice is yours on how to get there... please search thoroughly, as it has been covered an insane amount of times.
But, to try and answer your questions:
-Yes, the pre-requisites are that you need to be rooted, and have a custom recovery installed on your phone.. and an sdcard. You can do it on your rooted GB phone, but you cannot restore a GB backup while you are on ICS (for the only way to have the option to return to GB from ICS, you need to look here and here - but some will say there's no reason to go back to GB.. maybe nostalgia )
-A backup will backup your current system, data, and sometimes cache - and it will usually make a new folder, named by date, with a few .tar files inside of a "clockworkmod" folder on your sdcard. And yes, those are what you restore (when restoring, you choose the backup by date/folder name).
-No, you can not restore a GB backup from Numa (see above comments.. again) - also see here for a note on compatibly between different custom recovery options (might be easiest/safest to use BMM, I think you can flash all ROMs with that now..)
So if I understand all that correctly, here is my summary of steps to install Numa. Appreciate if you can correct my steps in-line if I am wrong. [Current state of my phone: Atrix2 on stock GB (AT&T). Only thing I have done is uninstalled/removed unwanted apps.]
Steps:
1. First get on ICS leak-1 following Jim thread. [OR OTA to the official/final ICS. But if I do this, I lose the option to return to GB? or will I loose that ability regardless since Numa itself is based on final ICS OTA?]
2. Install CWM A2 bootstrap recover from here.
http://forum.xda-developers.com/showpost.php?p=19355021&postcount=1
(No point taking a backup now I suppose since going back to GB isn't an option after Numa.)
3. Then follow the install instructions under the Numa Rom thread.
4. Once I have Numa up & running, I suppose I am limited to putting only those ICS/JB based roms that don't require me to be on leak-1?
On a side note, I hate how they have removed the "contacts" tab, "Only show contacts with phone number" option etc... from the Dialer app in ICS and replaced it with the People thingy . I like GB dialer. Also, In ICS they seem to have removed the data saver option that was available in GB.
Thx

If you uninstalled any stock apps, the installation of the update will probably fail, and you will either need to fix your system by replacing everything (very carefully).. or just FXZ back to stock GB<--post is a bit out-dated. [Yes, if you ota to final ICS, you can not return to GB ever. It doesn't matter what the ROM you flash is based on, they basically only change your /system partition (and data) - the problem is the new bootloader in final ICS.
Make a full backup of your stock ICS if you want to go back to it (see below - probably best to use BMM to backup)
2. Install CWM A2 bootstrap recover from here.
http://forum.xda-developers.com/showpost.php?p=19355021&postcount=1
(No point taking a backup now I suppose since going back to GB isn't an option after Numa.)
You could use that, or BootMenu Manager (I heard that it works to flash roms now - it used to not - and I personally have not tested it recently.. so, not sure - and we also have Safestrap, but not sure of the status on that - still a wip, I think). Either way, you will loose it once you flash Numa... you will need to reinstall it to flash a different rom or make a backup (I recommend using BMM to make a backup since it's compatible with the CM10-based recovery, and since it is easy to uninstall)
3. Then follow the install instructions under the Numa Rom thread.
Yup.. maybe a bit outdated also, but wipe data/factory reset, dalvik-cache maybe, then install zip..
4. Once I have Numa up & running, I suppose I am limited to putting only those ICS/JB based roms that don't require me to be on leak-1?
You can put any ICS/JB rom available for our phone, if you wish - or restore the backup you made of stock ICS before installing Numa
On a side note, I hate how they have removed the "contacts" tab, "Only show contacts with phone number" option etc... from the Dialer app in ICS and replaced it with the People thingy . I like GB dialer. Also, In ICS they seem to have removed the data saver option that was available in GB.
There are other ways to get from dialer to contacts in ICS (underneath the favorites tab, scroll down.. or is that only jb?)
Thx
No prob. Good luck.

[Q] How to reflash a new rom?

Hi!
I flashed pac-rom but it keeps my phone awake 24hrs even when i am sleeping therefore 70% battery consumption when i am sleeping and everyday i have been posting in that thread for help or update but dev has left,and this was a stable version with never ending problems for me.So i want to remove this and see if the other rom also behaves like this or not.
I want to remove this rom and gapps as well but i am a newbie and never did this before.I will be really grateful if someone guide me step by step in this.
Please reply soon coz i am not able to live a normal life as battery is creating problems for me.Thanks a lot in advance

As i said i am newbie things are not clear to me and what i asked in the question is not mentioned clearly and exactly.And since 7 days i am stuck in this esp last three days coz either the rom is a problem or need to be reflashed.And how to remove gapps etc that is not clear dear.Anyone who has a helping nature would write few lines or steps if he wants to help.My head is screwed up with this rom,nothing is working properly and all the time i am busy with my phone.Can't even open my eyes now as i have been continously looking at small screen.
Do not know if i have to reset the phone again or what,how to remove gapps as i do not have google store,gmail and maps in that. I always try to help a newbie coz i know he will not understand things clearly and can screw up,and in my case an experience person can tell if it is some thing else i should do along with that i.e if he would be concerned.
You are the king man so you would not know these small petty things.
Anyway thanks for whatever best you could do.
@kitu34: The procedure for flashing a new ROM is always the same:
1. Download the ROM, put it on your SD card (I recommend creating a folder in your SD card for your ROMs, kernels, etc., so that they're all in one place, but that's just a suggestion, not a requirement. Optional: Download the recommended GAPPS package for the ROM (if the ROM comes with built-in GAPPS, no need to download this).
2. Boot into recovery. You should be able to reboot into recovery simply by pressing power button > reboot > recovery. If not, then shutdown the phone and press & hold power+volume down+home.
3. In recovery, perform a factory reset (wipe data & cache), wipe dalvik-cache, and wipe system.
4. In recovery, flash the zip of the ROM you want to install (the procedure for this depends on your custom recovery; just browse around the menus for the option to flash a zip). If the ROM has a separate GAPPS package, you can also flash it here. Note: Always flash the GAPPS after you flash the ROM, not before.
5. Reboot system.
Flashing a custom kernel uses the same procedure, except you only wipe cache & dalvik-cache in step 3.

Update the ROM? Do you mean flashing a newer version of the same ROM? Some ROMs can be updated by simply wiping cache, dalvik, & system (no need to wipe data), then flashing the new version. Personally, I advise doing a clean install every time when installing a new ROM, even if it's just an update. That means a full wipe: data, cache, dalvik-cache, & system. A clean install helps you avoid potential errors.

If you want good battery life, then I suggest staying away from Jelly Bean ROMs for now -- the battery drain is huge. If you want to try a stable JB ROM, then the latest Jenkins build is good, as long as you don't mind battery drain and a couple of relatively major bugs (those being bluetooth A2DP not working and wifi hotspot reboot).
If you want a relatively more stable, but still high-end, ROM, then stick with ICS. Hephappy's CM9 is good (check the thread in the General LG-P500 forum), or if you want a tweaked & modded ICS, then get neko95's ICySNAP.
That said, the king of battery life still is Gingerbread. I'm personally using the latest unofficial CM7.2 build by FitAmp; it's stable and with good battery life, better than ICS or JB.

ok then for now i will try jenkin's coz that was the first rom i downloaded on my pc but did not flash.actually i have serious battery and other issues that is why i am just getting rid of this now and then read about the roms you mentioned.after fashing i will tell you how it goes and if that also has a battery issue then the next...so kind of you to help as there are very few people here who really want to help.(the other day grgtm from cebu really helped me when my phone went in fastboot,cebu guys are damn good hehe)thanks a lot
4. In recovery, flash the zip of the ROM you want to install (the procedure for this depends on your custom recovery; just browse around the menus for the option to flash a zip). If the ROM has a separate GAPPS package, you can also flash it here. Note: Always flash the GAPPS after you flash the ROM, not before.
I am doing with jenkins as i already have but it does not have gapps as i am not flashing the very last update which has gapps with it.\So is it ok to use rashed's cm10's mini gapps?

Yes, Rashed's mini gapps is for all cm10.x roms, including the Jenkins builds.
Edit: By the way, grgtm is from Romania, not Cebu (Philippines). You probably got him mixed up with someone else.

The home button not working is a result of a GAPPS error when the system partition is too full. You'll need to trim the ROM prior to flashing (search the cm10 thread; it's too complicated for me to explain here) or download the version of cm10.1 with built-in GAPPS. The fact of the matter is, our phones has a very small system partition, hence why we have to go to all this trouble when using JB.

Thanks,but first i am trying to reflash coz in the first time i wiped even cache partition and now i will try without that coz i did not yet get an answer to how to trim
You're seriously going to need to learn how to help yourself, @kitu34. Instead of asking for step-by-step instructions all the time, try looking for them yourself; simply using the "search this thread" function and running a search for "trim" in Rashed's thread would give you what you need. In fact, here's the link to the program used to trim ROMs: http://forum.xda-developers.com/showpost.php?p=33349661 -- that link was in the first post of Rashed's thread, labeled (and in very big letters) CLICK ME. The instructions for using the program is also in the thread, and the program's interface is so simple that simply browsing around should tell you what to do.

That link to the website is closed,i mean the website is closed.Bye
I tried Jenkins with rashed's mini gapps and worked perfectly(except battery drain), instead using an tool for rom editing, use an app like root uninstaller to get read of unnecessary apps to free some space on internal memory or use an d2ext script(but it got some strange behavior from my phone, you need a really fast sd card, an class 10 for that, and a reliable brand, mine is class 4, so in the final, sd card will worth half price of the phone)

Thanks,i have both titanium and es explorer,can i do with that by simply uninstalling system app? Actually someone told me not to this way and instead trim the rom.Even i am confused what is the difference.Either it creates problems or the amount of space we get by uninstalling with titanium is less compared to trimming the rom.
I will later what i did later.
