Hi I am going to be rooting this phone soon but before I do I want to make sure I fully understand everything I do because I am nosey and this is how I learn. So I ask alot of questions usually NOOB questions.
So As I understand it All I have to do is install a custom kernel which has clockworkmod on it. Now when I do that is CWM installed on the recovery partition of the phone so if all else fails I can still get into CWM to install a backup? I know if you use rom manager it fake flashes and the only way to get into CWM is through rom manager and mif the phone wont boot you are screwd. Also this phone has download mode is that a factory way to flash things? Like when I install a ROM do I flash it in download mode or do I flash it in Clockworkmod or do both work? Also I noticed that there are different versions of this phone I am guessing for different carriers. I have SGHt-989 so are all ropms okay for all the model or are they model specific? It seems that the 9100 is the most popular model. I am sorry for all the questions but as soon as I am comfortable with this device I can start to understand it.
Thanks alot
Charlie

Rom manager only does fake flashes. Only way to get cwm on our phone is via flashing a kernel that supports it.
Download mode can be used for first time rooting (to flash kernels), also for flashing roms via odin.
Once you're rooted, with a cwm supported kernel, you can use the clockwork recovery to flash roms, or even kernels. This way, it deosn't increase your binary counter.
i9100 is more popular because it is the international model and most common.
I had a Optimus One earlier and the way it worked there was flash CWM through ROM manager and no matter what kernel you use CWM would stick.
I wanted to know why in SGSII kernel comes with CWM inside it and does not work
standalone like it works in many other devices.I tried searching for answers but could not.
Thanks.
You can't flash cwm through rom manager because the stock kernel won't allow non-signed zip's, so signature verification has to be disabled in the kernel, i guess the dev's then figure what the hell lets throw cwm into the kernel while we're making a kernel.
Hope you can help me. I rooted my friends phone via odin. When i was about to flash a rom via cwm recovery mode - its opening to a "manual mode", im unable to flash the rom. Hope you can help me with this. Thank You
which rom are you trying to flash via cwm?
did you copy the rom to your internal sd card so that cwm can see it.
Ok guys heres the deal....i recently got a samsung fascinate from my sister cause I couldnt mod my inc any more. ok so....i got the phone rooted. i have su perm. i downloaded rom manager and installed it. now heres my problem. i can preform a backup no problem, but when i go to restore that backup it boots into clockwordmod and begins and then get an error about erasing boot img. or something like that. can tell exactly if i get some help from this. also cant install custom roms like i can with my incredible. i know it can be done cause i see roms and all for this phone. can someone please please help me.
Thats because cwm3 will not perform nandroid restores on stock roms. You need to flash cwm 2.5.1.x red recovery. Its the best recovery imo for any bml(touchwiz) rom. Go over to my guide in general section and you cand find cwm 2.5 in section 2&5. Oh and ditch rom manager...manually install cwm via odin!
If you're coming from an incredible, also keep in mind you don't have to be rooted to flash roms either, you just have to have a custom recovery. There aren't really any modifications like rooting procedures, S-OFF, etc, required for rom flashing, just odin a recovery and flash your selected rom.
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
Hi,
I am unsure about how to flash a ROM on to my phone.
I have already rooted it and installed a insecure kernel using Odin and the Samsung Quick Root tool (found here: http://forum.xda-developers.com/showthread.php?t=1125414). :victory:
I am still running the insecure kernel that I flashed with Odin, and did not install CWM as I do not know what to do.
ROM Manager is installed on the phone but I don't think CWM is actually installed.
Currently, I want to install the F1 Galaxy Nexus ICS ROM. (http://forum.xda-developers.com/showthread.php?t=1601518)
All I want to know is do I need to install CWM, and how to install and flash the ROM to my phone.
The exact model of my phone is i1900-XWLPI.
Thanks.
Hi.
Yes you need cwm.
How to install Rom always be a guide in thread...
Send form Galaxy S2. Using XDA Premium
I was following a guide on it.
Now I am worried
I think it is bricked as it is stuck on the yellow triangle screen.
I don't have a jig and I NEED IT WORKING.:crying:
Ok I managed to get it to go in to d/l mode and flashed kernel back to the one I had earlier.
I think I'll just leave it for today and try another time.
Too much happened today and I don't want to risk a permanent brick.
