Custom Roms - Galaxy S II Q&A, Help & Troubleshooting

Hey Guys,
Just got my new Galaxy S2 Yay, Can I jump straight into installing custom roms with Odin or do I need to do something first?
Regards,
Fenlig

Normaly custom ROMS come in .zip formats and if I'm not wrong you have to flash them via CWM recovery. For this you have to first root your phone:

Then flash a kernel that installs CWM recovery, I use CF root.

Then you put the ROM in internal sd card, reboot in CWM recovery and flash the custom ROM.

[Q] Confused about ClockWorkMod

Hi everyone. I'm running Galaxy Ace, stock ROM Android 2.3.4
Never flashed a custom ROM before, so be gentle.
Phone already rooted (I have the superuser icon)
From reading threads here at xda, I have download these 3:
1. ClockWorkModAce.zip
2. recovery-clockwork-5.0.2.6-galaxyace-fix.zip
3. GT-I9100_ClockworkMod-Recovery_4.0.0.2.tar
I'm guessing number 3 is not for galaxy ace, right? So that leaves 1 and 2.
QUESTIONS:
1. Are 1 and 2 essentially the same thing? Which do you suggest I use?
2. These two files are on my laptop. Should I simply copy either one of them to my phone's sd card, turn off phone, boot into recovery by pressing home and power button simultaneously, select "Apply update from sd card", then select either ClockWorkModAce.zip or recovery-clockwork-5.0.2.6-galaxyace-fix.zip?
3. After installing either of the two files, and rebooting, would "nandroid" be on my phone then?
4. I believe nandroid backs up EVERYTHING into sd card (recovery image, right?). Can I then copy it to my thumb drive or laptop so I can erase it from the sd card?
5. If I want to get back to my stock ROM, is it done by booting into the custom recovery (like the clockworkmod) and selecting an option there?
6. After going back to stock ROM, how would I go back to stock recovery too?
7. For clarification, when you guys are saying cwm or clockworkmod, do you mean ROM Manager? Because a lot of guys are warning me against it! I just found out clockworkmod is the name of the developer, not the app.
8. From the ROM Manager page at market.android.com ,
Samsung users: You must flash a Clockwork compatible kernel first (see XDA forums)
Is this really necessary?? So much prerequisites! =P
9. Should I install ICS Beta Full on my Galaxy Ace Android 2.3.4???
10. Already rooted, so how much time will it take from installing cwm to installing the custom ROM? I want to know so I won't panic
11. If I install cwm, does the recovery automatically becomes the custom recovery?
12. What does a full wipe mean and do I do it with the stock recovery or with the custom recovery?
Please be as detailed as possible, and use small words.
Appreciate it guys!
Thanks a lot!
first zip is for cwm4 official one
second is cwm5.. i personally prefer cwm4 as had no problems with it
cwm5 failed to take backup when i tried to several times
and i have flashed all roms that claims to do it with cwm5 with cwm4 with no problems at all
you can copy backup images to laptop but DO NOT modify names of any folder as it will result in mismatch of md5 so copy directly folder as it is without modification
ROM MANAGER IS ***** DO NOT INSTALL ON SGA or else you loose your device damn
you can flash it on stock kernel as well
if you want to go back to stock rom from restoring backup then your backup must be taken after converting filesystem to ext4 or else it will fail..
so before backing up flash cf-root and convert fs to ext4 to save time of flashing stock from odin and then restoring backups
thats your option to install cm9 on phone as its not stable and needs many changes at this time.. if you are ok with bugs then you can
1. yes u should delete it. judging by the name its for sgs2, would brick ur phone instantly if flashing that one.
2. i dont really sure about cwm 5.0.2.6 (ur second file) either it can be flash from stock recovery or not but the cwm 4.0.0.6 (ur 1st file) definitely can. and i think its "install zip from sdcard" in stock recovery to flash it.
3. yes.
4. yes, its located in /sdcard/clockworkmod/backup.
5. yes.
6. by flashing stock rom via odin.
7. nope. here if we said cwm or clockworkmod, its referring to the recovery itself (clockworkmod recovery). rom manager is different thing, a tool used to flash cwm or rom. and yes, u should avoid it as countless sga already bricked because of it. and yes, clockworkmod is nickname of the guy who created it and named it as clockworkmod recovery, and here we just called it cwm.
8. again, avoid using rom manager
and u probably wanna read this

1.First one is official CWM recovery..Its v4..Second one is unofficial CWM recovery..Its v5..I didnt have any problem with them both..But,you should not rename the backups you take with cwm5,it will give you a md5 mismatch error when you do that..
2.Yes..Just copy the file to the sd card
3.Nandroid is a feature of CWM...So,yes.When you flash cwm,you get Nandroid backup
4.Yes...It backsup everything on your phone.But as amit said,Dont rename them
5.By stock,if what you mean is,an untouched Firmware,like the one you got from the factory..Yes..But if you are going to flash any roms,it may convert the system partition to ext4,which will result in a bootloop if you try to restore the stock you have now.So,a better option will be to flash with Odin
6.If you go back to stock,you would still have cwm as your recovery..If you want your stock recovery back,you will have to do a flash with Odin(But,trust me,You will never feel to go back to a complete stock rom and the stock recovery after you start playing around with the other cm7 roms
7.CWM is a recovery..ROM Manager is an application..ClockWorkMod recovery is not a developer..Koushik Dutta is the developer of both CWM recovery and Rom Manager..If you have any thought about using ROM manager,then i suggest that you clean that thought because ROM manager does NOT support Galaxy Ace and if you use ROM manager to flash a rom,you are going to BRICK your device
8.Nothing like that,from what i know.I never flashed any kernel Right after i rooted my ace,i flashed cwm recovery..I didnt do anything else
9.Its your choice..The Myth Ics is an awesome rom
phew....

about number 5 and using odin in general
Hi. Thanks a lot guys for your effort in helping out a newbie.
I'm a bit confused about using odin. Is odin like the "safer" way to flash ROMs?
I know I can flash a ROM via booting into recovery, then "install update from sd card", and selecting the ROM. Does Odin do the same thing? When exactly should Odin be used? Only when I want to go back to my original stock firmware AND the original/stock recovery?
Thanks!
As far I know, ODIN is only for flashing stock ROM's.
And well, even if it can be used to flash custom rom's,please do not use it. ODIN can brick your phone. Flashing via recovery is the most safest way
further clarification
Hey guys, thanks a lot. Please clear these up for me:
1. If I am now on stock ROM (never flashed a custom ROM before), then I flash a custom ROM like TheMyth ICS Beta 2 Full, and wish to go back to my stock ROM (which was backed up with clockworkmod recovery), do I simply boot into cwm recovery and restore the stock ROM or do I use Odin?
2. If I am now on stock ROM (never flashed a custom ROM before), then I flash a custom ROM like TheMyth ICS Beta 2 Full, and wish to try another custom ROM like cyanogenMod, should I just flash cyanogenMod with cwm recovery? Meaning, from TheMyth ICS Beta 2 Full straight to CyanogenMod via cwm recovery? Or do I have to go back to stock ROM, as well as stock recovery, by using Odin, and then flash cyangogenMod via stock recovery?
3. If I am now on stock ROM and wish to upgrade to an official android version thru samfirmware.com, do I simply flash it with the stock recovery or do I have to use Odin?
Thanks a lot guys!
1- yes
2- yes, straight away. no need to go to stock rom
3- odin

Help with rooting and installing custom rom

Hey everyone,
i've got an i9300 device with 4.1.1 (XXDLIH) on it
I wanted to installed a custom rom on it (Omega ROM v38)
First i flashed CWM via Odin like in the instructions, after that i downloaded the rom put it in the sd card and booted the phone into CWM, i did the wipe and factory reset and choosed the rom zip for installing
After about 10 minutes the phone rebooted, but it is still on stock rom, so i thought what could the problem be and remembered that i need to root the phone first.
Now i have the problem that i can't (don't know), i don't know which way i should use for rooting so that i can afterwards install the Omega Custom rom ....
Note that i have now the CWM 5.5 recovery and don't know how to get back to stock recovery ...
Please if someone could tell me exactly what should i do, how exactly to root it and install the rom :/
Thanks everyone in advance
If you think that it would be better to install another custom rom then feel free to tell me

[Q] Is it possible to flash new roms via temp cwm

I have rooted my s2 I9100g. nothing more. I have temp_cwm.zip. Can i flash roms OR flashing blazing_safe kernel is necessary.
Yea you can flash kernel and rom with temporary cwm. But I advice you to flash kernel with permanent recovery and then flash rom.

Confused about rooting, recovery and custom roms

Could someone provide me with an easy guide to rooting, installing recovery and installing a custom rom on my S2? I1900 version.
I'm wanting to put a KK rom on it but I'm confused about which recovery to use and the best method for rooting.

I read your post on another thread you said you have flashed siyah kernel, so you are already rooted. You just need to use a "kitkat compatible" recovery such as CWM 6.0.4.5+ or TWRP 2.7+ to flash kitkat roms
Just a quick google search for "kitkat compatible recovery" gave me this one. Just download the CWM .zip, flash it from siyah recovery, then reboot to recovery(not system), then do your wipes/backups and flash the rom and gapps you want and reboot to system. Done
will give this a go!
