to install new rom - do I need root ? or I can through Samsung recovery ? - Galaxy S II Q&A, Help & Troubleshooting

meaning - can I just inter recovery (without odin) > and just flash a new rom + rtl ?
or the root is the thing that letting me do that from the first place ?
THX

You dont need root to flash anything.
Use odin.
(do some reading before attempting though & dont rush your first flash - be sure on everything!)
Good luck.

If you want to flash a custom ROM via recovery, you'll need to have CWM recovery. The Samsung stock recovery won't work. You won't get CWM recovery without root, so yes, you do need root if you want to flash custom ROM via recovery, or you can just use Odin to flash any stock or Odin compatible custom ROM. For Odin, you do not need root.

Custom Recovery

Hi, I have a Galaxy S2 with stock ROM 4.0.3 and stock Recovery. I wanted to know if there is a way of flashing Custom Rom without rooting the phone or ADB. Would this method work? http://forum.xda-developers.com/showthread.php?t=1501719 I would just proceed till the step "Choose CWM.zip and wait until CWM recovery appear." Would this work? i need custom recovery so i can flash a custom ROM.
Thanks again
No you cant flash a Custom ROM from stock recovery, you need a custom recovery and root access on your phone for flashing custom roms
the method you linked is only for rooting, the recovery appearing is only a temporory one from which you can only install SU-Busybox-Installer.zip.

I didn't test it myself, but I think that it will work.
If the custom ROM is provided as Odin-flashable tar file, you don't need a CWM recovery to flash it. Just put the ROm tar file into PDA section of Odin and flash it to your phone.
Only if the custom ROM is available as CWM-flashable zip file, you need to flash a kernel containing CWM recovery first.
I prefer to flash CF-Root kernel from Chainfire with Odin. It contains CWM Manager app and CWM recovery of cause.
When you are in doubt, stick to the flashing instructions of the ROM developer - usually in the corresponding ROM thread.
P.S.:
As soon as you have CWM recovery, create a nandroid/system backup.
So you will be able to go back to your current system, if something goes wrong with the new ROM.
Good luck !
Oh cool, lemme try it

All you need to do is download cwm recovery from here http://clockworkmod.com/rommanager in your SD card and flash the Dowloaded zip from stock recovery .
Once you flash, your stock recovery will be converted to cwm recovery
After that flash any custom rom of your choice. Simple and short

No you can flash any ROM you want, just like any other cwm.
I have used it multiple times, but the Queston is can you do it the first time, before you choose that busy box installer.
Edit: yes you can flash any rom just fine

Flashed new dx9 after full wipe.
From recovery choose the cwm zip
From that touch cwm flashed aosp rom.
So it works just fine.

[Q][9100G] Cwm recovery

I installed cwm recovery(.zip) and I know that it is a temporary recovery which after reboot it reverts back to stock recovery. My question is I am ready to flash roms or I have to get a permanent recovery?

If you have CWM recovery then you are ready to start flashing new roms.
Please keep in mind that your phone must be rooted - This should already be done seeing as you have CWM recovery.
You already have CWM permenantly on your device since you rooted ur device with CF kernel and as long as you have superuser and cwm file on your device that means u are rooted
You can now start flashing any rom you want
You can delete ur CWM from ur device by flashing stock ics kernel throught odin

Cf root will give u root and CWM recovery, so u're be able to install custom rom
1. Download any version of CWM from here
2. Get desired rom (kernel too if you want)
3. Place everything in Externel SDcard
4. Boot into stock recovery (Power+Home+Vol up)
5. Use stock recovery to flash CWM
6. Backup Current stock rom
7. Wipe the usual
8. Flash Custom rom (Or just kernel)
9. Reboot
10. ?? Profit ??
Now you got Custom rom or Kernel + Full stock rom backup (can always get stock rom from sammobile if you lose it)

Thank u for the response. But im a bit scared flash or wipe in temp touch recovery. Because a friend of mine got his s2 super bricked while trying to flash on stock 4.04 kernel. does this emcc bug affect 4.03 stock kernels as well? So can i just flash the latest Siyah Kernel using ODIN ??
Any time you root/flash a Rom theres a chance to brick your phone. What -Grift- said is the easiest and best way to flash a custom Rom in my opinion. Just make a Nandroid backup, delete data and cache, install the zip file from your SD card. I've flashed 4 Roms so far with this phone, all successfully. Currently I'm running Cyanogenmod 7 on my DINC 2. Good luck on whatever method you choose.

Go into download mode, connect your phone to your computer and use Odin to flash a custom kernel to your phone. That done, you have root and you're safe from the emmc superbug. (EDIT: although 4.0.3 doesnt have the bug, if thats what is bothering you) You can then flash a custom rom or whatever else you please. Use the TAR version of siyah v4.1.5 from www.gokhanmoral.com
Instructions on how to use Odin are available all over this site and on the web in general. Search and you'll get it.
If you don't wanna use Odin, your only other option is flashing temporary CWM. Search for rachmat3's method or use the one mentioned above. All three are equally safe provided you read up on the procedure adequately.
99.9% of the phones getting bricked is coz people jump headlong into the procedure without first bothering to educate themselves on how to go about it. They get what they deserve.

If noobs on xda have taught me one thing, its that smartphones just aren't for everyone.
Or just wipe only when you have flash the rom (custom recoveries are safe e.g siyah dorimanx)
Edit: AFAIK 4.0.3 are safe the bug is with leaked 4.0.4?

Yes, aslong as you have cwm you can then flash zip of your choice. The zip will also flash new kernel which has perm cwm.
Depending on which rom you flash, afterwards I would then go back into recovery (cwm) and flash Siyah kernel.

[Q][SOLVED] Custom Recovery HELP ?

I'm on 9300XXUFME7 – Android 4.2.2 Jelly Bean
I haven't installed any custom recovery yet.
But i want to install philz advanced cwm or ClockworkMod Recovery
I heard that philz advanced cwm is the best
I have a few questions so plz help me
1. Which Recovery is the Best ?
2. Does installing a custom Recovery void Warranty ?
3. How do i uninstall a custom Recovery and revert back to stock Recovery ?
4. Does flashing Rom's uninstall custom recovery ? (Like flashing un-root our device )
5. Does Rooting is mandatory to install a custom Recovery ?
6. Does Custom Recovery is mandatory to install Custom Rom's ?
laura almeida said:
I
1. Which Recovery is the Best ?
=> not allowed to ask , but select one that includes a SDS fix e.g. Philz
2. Does installing a custom Recovery void Warranty ?
=> I would guess so
3. How do i uninstall a custom Recovery and revert back to stock Recovery ?
=> flash a stock ROM, or try to find a flashable stock recovery zip
4. Does flashing Rom's uninstall custom recovery ? (Like flashing un-root our device )
=> only if flashing a stock ROM that includes the stock recovery, custom roms usually don't include one.
5. Does Rooting is mandatory to install a custom Recovery ?
=> not sure about that as you also can flash roms without root via Odn
6. Does Custom Recovery is mandatory to install Custom Rom's ?
=> not 100% sure, whereas see (5). custom recoveries nevertheless will give you more options to e.g. backup

see answers above.
Just to add to the above regarding 5 and 6.
5) You do not need root to flash a recovery. Just Odin. You can flash a recovery then flash a custom ROM directly without having to root your stock android rom.
5) Most custom ROMs are .zips for recovery. Its rare you find an Odin flashable custom ROM. Sometimes the early versions of Leaked samsung ROMs are Odin flashable and rooted but that doesn't really count.
Can anyone provide me a link to Flashable Stock recovery zip ??
So, If i flash my phone with I9300XXUFME7 – Android 4.2.2 Jelly Bean Do i get my stock recovery back ?
I would recommend flashing via odin. You can get stock recovery from any stock rom or cf autoroot.

As rootSU said every stock ROM has it. If you got mobile Odin you can select the zip and just eject the recovery partition I suppose. This will enable you to just flash the recovery without Rom.
