Hi I have a Samsung Galaxy S2. Android v4.0.4 LQ7
I am a noob so sorry if my question is stupid.
I have rooted using method 1 in that thread and it worked great.
http://forum.xda-developers.com/showthread.php?t=1746794
Then I downloaded the app ROM Manager and downloaded CM9 RC2 since it appeared to be a stable.
I used ROM manager to download the file cm-9.0.0-RC2-galaxys2.zip
Once downloaded I saved that file in the external SD Card and used ROM Manager to reboot in recovery mode and install the ROM.
The installation progress fine and complete. I then reboot my phone.
When rebooting the phone displays the Samsung galaxy S2 screen and then switched to Cyanogen (mod) 9 screen. From there nothing happens. The phone won't boot. I tried to removed the battery which is the only way to turn the phone off and reboot in recovery and reinstall the file but the same thing happens.
Please help!
You've probably installed wrong zip for your device/variation.
Specifically which GS2 have you got?
Did you wipe date/factory reset?
Try wiping before and after flashing?
Get the CM9 nightly and flash that instead or try flashing Siyah kernel over the one that is on your device now. I personally use Goo Manager from market as you can download/update/notifications and browse compatible roms via that.

I have a GT i9100 Galaxy S2.
what would happen If I did a factory reset/data?
All I did was installing from external SD card nothing else.
Thanks

If you do a wipe/reset it will clean all your installed apps/app data and restore settings to clean install.
Its advisable to do this whenever you are flashing a different rom. Its easy to backup and then restore all your apps automatically and silently (without intervention) in a few clicks after installing new rom with titanium backup (pro).
Reboot into recovery
Wipe data/factory reset
Install CM9 Nightly from internal or external card.
Install latest CM9 gapps
Reboot system.

Gapps is basically Google apps it gives you the play store and sometimes face unlock. Did you wipe cache and dalvik cache before updating to CM9? That's one of the main reasons why ROMs don't boot up. Also first time boots do take a while about 10-15mins...

Hey yeah it did help thanks. I have now a working phone again. I am getting used to CM9 it is such a smooth OS. By the way on ICS 4.0.4 i was able to get the battery percent number displayed on the top near the battery icon. I can't find that on CM9? it used to be in the settings/display on ICS
Thanks guys

Thanks. for that. Do you guys know of a shortcut button to turn the mobile data on or off, like the power button does on ICS?
Also I would like to raise an issue with the ROM Manager App. I cannot do a backup of my current ROM. Every time I try to do so the App freezes. It did the same when I first rooted my phone and I was on the Stock ROM I was unable to do a backup then.
Is this something that happen often with Rom manager?
Thanks

Don't use ROM Manager, due to its incompatibility with most kernels and the S2.
Here's what to do about the short cut for mobile data:
Options –> System –> Notification Drawer –> Widget Buttons –> Toggle Mobile Data
It'll be there at the top when you pull down the drawer, if it's not immediately visible just slide the icons to the side and you'll see it.

You always do backups in recovery mode, Rom Manager (if compatible kernel) simply automates teh process of rebooting into recovery and starting backup.
Depending on your rom/version you can do this via power menu anyway (reboot into recovery).
STOP USING ROM MANAGER!
It can & most likely will fuc& your fone up. If u want to learn I suggest u read all of chainfires posts, then check out the SGSII Bible in the GS2 section. Then get urself the correct tar file for the Cf root kernel specific to ur country or region. That will get u outta the ****e if this ever happens again. Read up on all things root etc. u could do with learning what Odin is too!

Thanks for that. I think I know what Odin is. Thank you so much for that post. You have opened a whole new world! I have opened the SG2 bible I wish I have done that before. I am about to do a back up now. but I have not been able to do a back up of my original stock ROM since I was trying to do it with ROM Manager and it would freeze all the time. I think it is the worse that I could have done I have changed my ROM and didn't not do a back up before. i guess I will never be able to revert back to my stock ROM. Thanks again for you precious advises they have been very helpful!
Naa m8, u can always go back to a stock, u just need to tell me your country & the modem & ROM version, mine was stock Uk 4.0.3 & once you have that you can flash it with Odin then flash the Cf root kernel. you would then be on a totally stock ICS ROM but with root & CWM recovery so you can then flash anything you like. If you give me the country & which ROM (ICS or GB) you would like I can give you the necessary files for Odin.
Do not, I repeat DO NOT flash a stock ROM & stock unrooted kernel as if u do a full wipe it will hardbrick ur fone!

There's an even easier way....
Go here...
http://forum.xda-developers.com/showthread.php?t=1608071
then simply download the stock unbranded firmware for your country. it doesn't have to be your specific country but it helps as it has the csc etc that you need. Once you have downloaded it simply flash it with Odin & you will be running stock ICS 4.0.3 but with root so you can then flash CM9, but seriously I would highly recommended Omega v15. It's close to stock but sooooo much more. Im in all day if u need help
Sent from My Omega powered beast, using Xparent ICS
Hey thanks for that. I was thinking of doing a back up of my stock ROM in case I wanted to revert back to it one day. I will have a look at that thread and let you know of my phone details too. I really appreciate your help. As far as using Odin goes I am not very familiar with it so I'll need to read a Guide on how to use it.

In that case you will need to flash an appropriate modem file for your device or possibly check APN details.
You can get modem via dev section (use search) and APN settings from your carrier or google.

So this is weird... In four days, the ROM or phone has froze on me about half a dozen times now. The first time when I was setting it up by as I had just done a flash of the ROM. While setting it up, the phone decided to suddenly slow down all of a sudden to a crawl, up to the point where everything started to get washed out and freeze on me. Force restart by holding Volume Up + Power was the only solution to fix it. Just now, my sister had it connected to her computer and was transferring music over into the internal SD when suddenly, the same thing happened. Again, only solution was to force restart. Anyone have this happen to them before? Everything is completely stock except that we're on Dorimanx 5.3 kernel. Then the other times, it would either slow down and freeze in the CWM Recovery Menu, or when she is texting, playing games, etc. There aren't that many apps installed at all. Reflash of kernel doesn't solve the problem.

try doing a wipe data/factory reset as that is normally a fix to these kind of problems. Also clear cache and dalvik and that should fix the problem!

Do not use the .pit file unless you understand 100%sure about what you are doing. That's probably the easiest way to bork your device.
Edit: try flashing a different kernel. Try dark knight or fluxi. I think it would solve your issues

I would get an official rom, and flash it with odin, (no repartition is required) then install your fav. custom rom

I can't wipe data/factory reset in CWM for some reason when I first tried to install the custom ROM. Never tried again... I wonder if it's because my I9100 is brickable.
I have cleared cache and dalvik cache but no luck. It even slowed down and froze in CWM Recovery.

I know what I'm doing. Flashed with PIT many times before on my Captivate. Haven't tried PIT on her I9100 though. I haven't broken my phone with PIT yet, even though there's quite a few PITs out there lol.
I've read of others running the same combo as me, but they're fine so I wonder what else could cause this...

Running the latest Dorimanx 5.5 kernel and still getting the same problem. In fact, I noticed that if you set it to Performance under Kernel Tweaks in Recovery, the problem is more apparent. Setting it to default causes the issue too.
Hi
I searched and only found similar cases with other phones and no solution.
I was on stock 4.0.3 with CWM, rooted and siyah kernel and tried to upgrade to CM9
with Rom manager
i dled cm9 with gapps and let ROM Manager do the backup, wipe and reboot to recovery
but then i just saw the first GT 9100i boot screen with the triangle and after that
the screen stayed black.
i noticed in a darker area that the screen blinked everey few seconds, so i guess its trying to reboot all the time. some kind of bootloop?
i cant access the cwm, nor boot normaly.
just the download mode is working
so i tried to flash a stock FW from intratechs thread via odin
but... FAIL
help would be much appreciated right know :crying:
thank you
Mmm I've had issues with rom manager before but never this severe. All I can suggest is what I would do which is to fash stock firmware from samfirmware via PDA section in odin. If this doesn't work I think there is a sticky thread which is dedicated to situations like this. It requires flashing a firmware via odin again but all partitions are used so it will wipe your device. All the best.

If you want a fresh start just format system whilst performing your wipes. Only do this with a safe kernel as anything based on stock 4.0.4 will brick your phone. When I ever change ROMs I just run wipes and format system then flash my chosen rom. That is the correct site and you can flash any rom for your phone regardless of region. EFS back up is a separate tool which you download on to your pc which then backs up the EFS folder. There are other apps that do this too. I use them all, can never have too many copies of it.

So if I just do all the wipes, it should be all good? There is a lot of files that I don't want if they don't belong to my rom, should I delete some or what should I do? The basic thing I am trying to do is only have files from apps that I have and ones that the rom needs.

I understand what you're after factory reset, wipe dalvik and format system will give you a clean installation in terms of rom. If it's a complete wipe you can wipe the sd card from setting /backup and reset. But this will wipe music photos too. Once rooted you can always browse the directories and manually delete any unwanted files/folders. Please check your kernel first.

How to stock > custom rom > 100% same stock?
Hello,
did not want to start new thread with same name, but my question a little different.
So I bought S2 and I would like to play with some custom ROM of course. Not my first Android phone, but new phone new unknown things.
I read many post, but it is still not clear if I can make my stock rom and kernel backup, then root it, have some fun and if I need just restore stock rom and kernel and every thing would be as it was new?
I understand how to root and this CF-Root in Stock Recovery method looks like can do this. But will it be that way?
For example, with this method I have my stock kernel backup, also make stock rom backup, install some custom ROMs/kernels and later just install stock rom and restore stock kernel using this method and I am back to starting point?
Hi, to return your phone to stock all you need to do is:
Make note of your current ROM and download the same from samfirmware
Download Odin
Perform full wipes and format system in recovery mode
Then into download mode where you flash the stock ROM in the PDA section of doing.
Included will be a stock kernel and root would have been lost.
To reset binary counter look at the app triangle away by chain fire.
All the best.

To restore a back up:
Boot into recovery mode
In recovery mode enter back up and restored menu
Then select restore from external memory / sd card
Phone will restore to the time the back up was made.
Some kernels have different CWM menu layouts but the above should get you to the Nandroid backup you made.
All the best

So yeah, my phone is like 2 years old and it started randomly shutting down. Before i go and buy a new battery, i thought i should put it back to complete stock (it is currentyl running siyah with some other mods and tweaks). Only way i remember to do this is by flashing a stock firmware through odin, i decided to do so but to my surprise nothing changed, i still had ALL my apps, SuperSu, extweaks and some other root/siyah-related stuff. how can i completely restore my phone back to complete stock ?

I think they were restored after u set up your google acount. If u had them backed on your acount automatcly install them after a google acount is inserted
Enter stock recovery and wipe data. Just make sure its safe for your rom to do so.
And at promp do not restore apps

Cmiiw.....but aren't those update zips there to update an out of date totally unmodded stock firmware.....OP says he's running Siyah.....
Not sure if it'd work in his case

I think they're meant to fool stock recovery into flashing a ROM (Because it thinks it's an update, you just have to rename it).
Check TiBu, you got an option to back your stuff into an "update.zip"
MO also allows you to flash one of those.

Hi guys, I've owned this tab (p4wifi) for a few years now and for sure loads of junk has been building up in it. I've used dozens of ROMs in the past and it seems to be slowing down. Now the slowness isn't the issue, I just want to revert it back to full, pure stock as in Unrooted stock ROM from sammobile with no user data whatsoever. Exactly like the first day I got the tab, no pics videos or anything that I took.
I live in Malaysia so I'll be using this: http://www.sammobile.com/firmwares/3/?download=5982
So now the problem is how to exactly go about doing this? I'm currently running CM10.2 with CWM installed and I want all my user apps, photos and videos gone too, like everything. I understand that i have to boot in Download Mode and use ODIN to flash that ROM image, but hat are the steps before or after that I have to take to remove all my user data? Would really appreciate it if I could have a step by step procedure.
Thanks alot guys

well before flashing the KERNEL image....
it is not quite necessary to totally wipe the phone..
bt to ensure a clean install it can be done...
while.... since u want to return to pure stock.... it is better to first restore your first cwm backup which u made just after rooting.....
coz flashing a kernel wont remove the custom scripts bt only disable it.....
so wat i say is... first restore ur just-after-root cwm bakup.... after that flash your kernel which u will download from sammobile. com.
and then u will have a pure stock unrooted phone like in the beginning

OK I will try. I'm running CM10.2 a custom ROM so can I use the factory reset option in system settings? Because CWM wipe data doesn't wipe a lot of things :/

yes you can use the factory reset and it will wipe everything.... from cache to dalvik cache to data..
the system folder and some other folders will only be intact as they contain the rom related files....

Do this:
1. Wipe data/factory reset in cwm
2. Wipe system
3. Wipe cache
4. Wipe dalvik
5. Wipe internal memory or sdcard or /data/media (I forgot what its called in cwm)
Then boot into download mode and Odin flash the stock ROM.
FYI, the other guy was wrong, sammobile offers ROMs and not kernels. And, HEY, I'M FROM MALAYSIA TOO!

Thanks both of you Woohoo fellow Malaysian on this legacy tab. Sweet thanks for the detailed procedure, I'm guessing step 5 is the one that wipes all photos and videos? Because normally 1-4 just wipes user apps. Will try it after having my stuff backed up How is the UI smoothness for you on this tab? Just wondering if I'm the only one who feels that mine is very sluggish.
actually, Toldo's stock rooted ICS rom and Omni Kitkat rom are both smooth.

Yup that's the one that wipes everything. Sometimes the tab feels sluggish, depending on what i use it for, like heavy multitasking and such, but overall its pretty smooth. BTW, I'm running SlimSaber 4.3 on my tab. I feel that 4.3 gives the best performance for our tab and 4.1(pershoot's cm10) is the most stable.

If you're going to revert to pure stock, just flash official firmware via ODIN. Boot into stock recovery and factory reset. It will also wipe the contents for internal sdcard.
.......
just use odin

Yeah hahaha.
How about kernel wise? Which is the best kernel out there for this tab? Would prefer a ekrnel that allows "powersave" and "performance" mode in trickster mod :3

On stock ROM? I'd recommend A1 kernel or Yoda kernel. Yoda kernel is quite outdated and doesn't contain the l2_hsic wakelock fix if you have the 3g version, but its pretty good. A1 on the other hand, is a fan favourite. Both have performance governors and if I'm not mistaken also powersave governor, but honestly I've never tried trickster mod so I can't tell you that.

Thank you sir, great help so far heh. I ended up flashing the rooted deodexed stock ROM i found in the forum but after flashing I chose to disable stock recovery flash, does that change anything? My first boot wasn't successful so I went to reflash the ROM again in CWM and it got stuck in "Opening update package". I restarted the tab and it booted up normally. Is the stock ROM interfering with the custom recovery? :3

Did you do the usual wipe before flashing? And also what version of cwm are you using? Try using this version of TWRP by kasper_h.

To answer your question, I don't think it changes anything, but saying no to stock recovery flash seems to be the right way to go. And no, stock ROM does not interfere with the custom recovery.

It's alright everything's working now Now another problem popped out I wiped my internal memory which means all my photos and everything non system related, and it did, my tab was practically empty buttt the tab doesn't register it as that ._. The storage part in settings shows that I have used up like 12GB of space even though I have wiped everything clean, I did an SD card folder analysis with ES file explorer and although it showed the same 12GB used, the folders shown do not add up to that, could it be the indexes are not updated? Because I don't see anything that could be eating up all that space

If the sdcard is empty, that means something is hogging your space somewhere in /data. What version of Android were you on before and now?
