[Q] Noob question (please dont flame) - Galaxy S II Q&A, Help & Troubleshooting

Right ive been researching for the last 3 hours. And i think im ready to root and install custom rom on my phone when it arrives. But i would like some clarifaction on the steps:
Install cf-root using odin- this should give me root and CWM?
use usb jig to get rid of yellow triangle and reset counter if needed?
Download zip rom and flash through CWM?
Is that about it or have i missed something? seems too easy.
Cheers

- Yes.
- Yes.
- Can't say.
- You need usb jig to reset the ROM counter.
- To remove the Yellow Triangle you need to flash back a Stock kernel via Odin and then flash the zImage of rooted kernel via CWM. No need to use Jig for that.

yes the jig get rids of the yellow triangle and resets the counter.

i don't mind having the yellow triangle because I'll be flashing rom updates almost every month.

Installed custom rom 24 times yet not satisfactory results (((((((((((
I don't know if its even funny or unusual but yes i downloaded like every single rom i could and installed it on my galaxy s2 but most of them got installed and phone got stuck on start samsung logo.Now i got it working.Here are the details what i got on my phone information.I want to know if it is any good or i should try more downloading.lol
Phone : samsung galaxy s2 GT-19100
ANDROID VERSION : 2.3.3
kernel version : [email protected] 2
build number gingerbread.XWKE1

Did you wipe the phone before flashing?
Some ROMs require that you wipe the phone's userdata (data) partition before flashing, or it will be stuck at the Samsung logo repeatedly.
Did you wipe the phone after flashing?
Some ROMs does not allow you to wipe the phone's userdata (data) partition after you flash it, or it will be stuck at the Samsung logo boot loop.

Make sure to backup your efs folder in case you loose your imie. A very important step.

How do I go about doing this? And how do I restore if I do

Ok from what I can gather there seems o be two ways of flashing roms with the SGS2. Using Odin and cwm. What are the difference between them? Advantages,disadvantages? Sorry for the questions I just like to know my stuff before I take a plunge into something

The rom builder decides the method of flashing you just follow the given instructions .
Essentially no difference .

How do I go about doing this? And how do I restore if I do

Clockwork Recovery, does not require a computer to update, change rom. You download the ROM which is in ZIP format. You can use your phone to download it. Then you boot into Clockwork Recovery and install it. You can also use ROM Manager or CWM App to install it as well.
ODIN requires a computer to install rom. ROM is in TAR format and you must boot your phone into Download mode, plug the phone to the computer, then flash the ROM using your computer via ODIN.
When using ODIN to flash a custom kernel, it increases the custom binary counter. A yellow exclamation triangle during the Samsung boot logo will appear if it is not there before.
When using Clockwork Recovery to flash a custom kernel, it does not increase custom binary counter. Since it does not increase the binary counter, there is no yellow exclamation triangle.

Hi Ricey.
Why don't you give the stock rom a chance.Get rid of some of the apps you don't want & replace others with better one's from the market. Have a play with the phone for a couple of weeks & get used to it before you root it.Who knows you might like the stock rom after all.

This aint my first android phone, its just my first samsung. I know from previous experience after 2 days i will be itching to flash ROM's, if for no other reason than because i can. Cheers for advice anyway.
right so to amend my original plan, i need to:
Install cf-root using odin- this should give me root and CWM?
Backup ESF folder using nitrality (does this allow the folder to keep permissions)?
use usb jig to get rid of yellow triangle and reset counter if needed?
Download zip rom and flash through CWM or ODIN depending on rom

The yellow triangle after booting??

Hi
I want to root my phone now but very un sure on how to get the yellow triangle not to appear after rooting??
Theres instructions through chainfire but i can't get my head around it in all respects??
the root process seems ok to do but I wouldnt want this triangle everytime I reboot. .
Thanks
Why do you want to get rid of the yellow triangle, does it hurt you somehow?
The yellow triangle indicates that the running kernel is not signed by Samsung. Obviously to get rid of this you have to flash a Samsung-signed Kernel.
While root usually will still work, obviously other features that are depended on the modded kernel won´t work.
If you're really struggling with chainfire's instructions, there's an excellent total baby-steps guide for noobs here.
But you can learn to live with the triagle - how often do you watch a reboot screen anyway?
Its pretty simple,
After rooting,
1- Flash back the Stock kernel via Odin.
2- Flash the Zimage from your SD card via CWM, which you need to copy to your SD card before step 1 from your rooted kernel.
Regards.

You don't need to do point 1 do you? Can't you just flash the kernel from CWM app?
Also replacing the stock kernel will still not reset the count will it?
If you want to get yourself a usb jig, this will reset the binary counter and remove the triangle. Search the forums for usb jig, plenty info there
Yeah so only the jig will reset the counter.
I assume that the download mode would still show custom unless you reflash the stock kernel as above through cwm app on a cfroot phone?
Sent from my GT-I9100 using XDA App
One thing I'm a little hazy on...
Okay say I have stock phone with KF3 kernel. I root using CF-Root (KF3) kernel and everything is great apart from the yellow box. If I re flash the using the cwm app with the stock kernel again this will remove the yellow box, overwrite the cf-root with the samsung stock kernel (thus removing cwm) but still leave the phone in a rooted state?
In this instance would I be able to install a custom rom using the stock kernel that I now have OR do I need to re-flash (using Odin) the previous CF-Root kernel to get cwm back?
I haven't done this process as yet as I'm waiting for a jig to arrive to do it that way but I'm trying to understand why you'd want to put the stock kernel back (as is shown in numerous guides)?
Also if I use the jig and it removes the yellow box and resets the counter, does it factory reset the kernel or will I still have cwm on there? If the later, will the download mode show a custom rom/kernel or samsung rom/kernel?

JIG it and if you dont know how to jig it ebay e.g.Samsung s jig adapter or build it very simple if your int electronic soildering and the yellow triangle can void your warrenty in short there is a counter which will show samsung how many times youv flashed your fone with an unofficial kernel. hope this info helps.

One important before rooting

I need to ask one more thing,So lets say i flash a custom rom like MIUI on Clockworkmod Recovery,will the kernel be flashed as well?
That means the triangle wont appear right?
then why use mobile odin and ktool?
Thx in advance.. Tried searching for ans,still can't find ...
Please help here

No, all roms are designed to be flashed by CWM.
Some roms come in tar files which require odin.
It depends on how the developer packaged it.

Then how do I remove the triangle permanently?
Sent from my GT-I9100 using Tapatalk
You can remove the triangle the easy way or the not so easy way.
1. Buy a jig off ebay, turn your phone off plug it in and your done.
2. Follow the instructions found on the cf root thread, don't just reflash a secure kernel because you will lose root. This process a little more involved but not too complicated.
ps if you have a rom with the new boot loader the jig won't work, that being said most devs include the old bootloader so it shouldn't be a problem. There is no way to permanently remove the triangle, if you flash unofficial kernels etc through odin the triangle will return so just use cwm to do your flashing and you'll avoid the triangle.

Newbie questions before rooting

I still have a few questions before rooting my phone for the first time.
1) if i root 2.3.6 using the right kernel, Can i still install an ics custom rom like resurrection?
2) if i root stock 4.0.3 Poland version or argentinian version, final result of installing a new custom Rom is gonna be the same because it completely replace the first one?
3) what's the difference between nandroid backup and cwm way to backup custom rom? Do i need to keep my backup inside the phone in order to unbrick it tomorrow, or may i just store it on my notebook and delete it from the phone?
Thanks a lot!!

1) Rooting is just to give you access to CWM.. ergo the ability to install custom ROMS so you can install ROMS after rooting
2) When you flash a new ROM (which is rooted) then you dont have to bother about what did you did before that..
3) If i'm not mistaken CWM only allows u to do a nandroid backup.. And if u want to restore to the backup ( in ur case unbrick :silly U need to have that in ur sd card :good:
Happy rooting.. Happy flashing..
1) Follow whatever instructions the rom you're wanting to use has to the letter.
2) If you install a custom rom, then yes, obviously it will replace any stock rom you flash it over the top of.
3) A CWM backup is a Nandroid backup. It's the same thing. You can store your backups wherever you want. I have my 4 most recent Nandroids on my phone, and I have every backup I've ever done on my phone stored on my PC (and another copy on an external drive I use for backups). So I guess the question you're asking is, can I take a Nandroid backup from ages ago stored on my PC, put it on my phone & restore it. Am I right ? If that's what you're asking, the answer is yes.
Thanks. Actually i was asking in case my phone bricks after installing a new rom. I guess i won't be able to come it back to life if i don t have the backup in the phone.
And one more thing. What is efs backup. Do I also need to do it?
Thanks
Sent from my GT-I9100 using Tapatalk 2
Yes. The 2nd thing you should do after your root your phone (first thing is do a Nandroid backup) is to get kTool from Google Play & backup your EFS. Before you install another rom or kernel do both of those.
Keep a copy on your external sdcard & keep another copy on your PC. Just in case you ever need it. We get quite a few people on here every week with IMEI/EFS details gone & most don't have EFS backups.
thanks!
I forgot to ask, is there any real risk at using triangle away app? So far, is it working on any kernel? thanks

I've actually used that app a few times well (about 5) and haven't had any issues but once you get CWM installed and you flash kernels through it you won't get the yellow triangle.

There will always be a risk when using anything that manupulates root access, but triangle away is quite safe, as for what kernel if works on, most kernel threads will say if it is compatiable or not, but only with ICS kernels, not GB kernels.
"...once you get CWM installed and you flash kernels through it you won't get the yellow triangle."
What do you mean by that? I actually don´t need to use the app, because triangle will dissapear anyway after flashing a Kernel?

You will still have the triangle after flashing a new rom or kernel, the best way to get rid of it is triagle away, this app will also reset your flash counter.
Once you get a working CWM, let's say you're using Cyanogenmod 9 and you want to flash over the stock kernel.
You'd put the kernel file on the memory of the device (sdcard) and boot in CWM recover and flash from there and you won't get the triangle.
The triangle won't go away now if you unless you use a USB jig or the triangle away app. So get rid of the triangle now and when you want to try a new kernel flash it through CWM and the triangle won't appear. Flash a kernel through download mode and you'll get the triangle.

Fixing permissions is automatic I believe in CWM recovery. It's an option in the recovery menu. Remember to wipe data and cache (dalvik too) when flashing a next rom or else you won't be able to boot.

Thanks for the info mate
By the way, you should really just buy a USB Jig off eBay for a few quid, it resets the custom binary counter (on old bootloaders) and can also force your phone into download mode after a bad flash. Handy to have around. Also, now that you have rooted your phone, download EFS Pro (found here on XDA) and back up your EFS folder before any flashing. Lose this folder and your in serious trouble!

Hi! When rooting or flashing a custom rom or kernel, do I lose internal sd card content?
Where is the EFS folder I need to backup?
Thanks!

Rooting Galaxy S2 GT-i9100?

Guys, is there any chance of rooting the phone without flash with odin or from the mobile odin?
Serve unlock root for ICS 4.0.3?
From already thank you very much.
PS: Sorry for my English is not very good
Look at the PhilZ-CWM6 custom kernel. It can be flashed in stock recovery and includes SuperSU, root, ClockworkMod Recovery and Busybox.
It is pure stock based, and doesn't have MMC brickbug.
Thanks for responding! But there would be some way that only makes you root, without installing a modified kernel and without CWM? is that I want nothing more root access

You're wrong pal, using the first method will only root your phone, no cwm nor custom kernel. its a single file u flash through stock recovery that gives you root and busybox, nothing else.
Thanks friend! Now I see it, I do not set it up yet because there is no custom rom, just want root : D

Try flashing a custom kernel through Odin on your PC. Plenty of guides on here and Google. That way you can flash cm through recovery. Keep an eye out for the kernel bug related to 4.0.4. Again lots of documentation on that too.

There is ALWAYS a risk when doing anything to your device. The level of risk is down to what you are doing and what state the battery is in etc.
As long at the rooted kernel you are flashing is compatible with the current firmware then all SHOULD be fine.

Stuck in bootloop
Hi,
So, this is what happened
I have a galaxy SII gt-i9100, About 5 months ago I rooted it and installed the galaxy nexus update to android 4.0.4. and everything was ok except it wasn't showing me the option to transfer via blue tooth (but that didn't bother me much). These were the things I used
1. GT-I9100_ClockworkMod-Recovery_4.0.1.4
2. Odin3 v1.83
3. GT-I9100_XWKI8_insecure
4. GT-I9100_XWKI8_original
Now, yesterday I a friend had galaxy S II i9100P and he updated the firmware using kies and it had working blue tooth. I thought ok let's change it to that and my blue tooth might work also. I was at work and I (in a hurry) tried rooting it with only Odin. No backup, No Clockwork :laugh: nothing. ( and "Now it's stuck at the startup screen. I can go to download mode and recovery mode but it has samusg recovery not clockwork. I don't know what to do and in need of help. I'd really appreciate a quick response. (hoping to get atleast the mass data back )
These were the only 2 things used.

ok, the galaxy nexus update? you mean Jelly Bean or Supernexus / chamaleon?
I think that you've installed a stock ROM over a custom ROM and that's why you are stucked at the logo.
read a little bit about flashing because you are up for it.
Learn about SD card data when flashing and follow a tutorial to flash stock ICS 4.0.3 via odin thru Download mode.
Also make sure to flash a safe kernel so you wont get the brick bug (see warning post sticked in the general section).
I don't know what to put here...any ideas?

i already have a nandroid backup before i was using omega ,a efs backup, and already backed up my apps using touchwiz
This is my first question on xda so i hope i gave you all the information you need
