[Q] Recovery via Custom recovery when install rom fail? - Galaxy S III Q&A, Help & Troubleshooting

Hi everyone, i'm gonna install a new rom for my s3, so i want to ask you sth before install it
First, if install stock rom via Odin fail, may i boot into custom recovery to recovery my android OS?
Second, if install cr via Odin fail, may i use my phone normally?
Last, if install rom fail, may i boot into custom recovery to recovery my android OS?
Sorry for asking to much, just because i have once installed stock rom via Odin fail and i too scared after that.

All things are flashed with Odin, including custom recovery so if you can't get that to work then nothing will happen.
Follow the guide in general forum sticky thread on how to flash with Odin, understand what you are doing before you start.

[Q] Question about rooting this phone

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.

What should do next after failing installing ROM's and having boot loops problems

Im tired of installing many ROM's and 2 different Recovery, some "cant open .zip" and having boot problems, and in other recovery, it can install roms, but other aslo cant open .zip, and also having boot problems,
Im really tired of reflashing stock ICS Fw then root, install Recovery again, after failing installing ROMs.. its too long to reflash, root, install recovery,, its waste my time and having headache after failing installing ROMs for almost a week
Is there any fast solution or what would you do after you fail installing ROMs and cant boot? even do you can enter recovery? what proper should do next? would you also reflash again stock ICS then root and install recovery?
or any other fast way solution..
Please help
Root and install recovery onto your device. Enter recovery and make a nandroid back up of your device. Flash your new rom and reboot the device. If you boot loop or the rom doesn't work or even if you just don't like it, enter recovery (may have to remove the battery to restart a boot cycle) and use your nandroid back up to restore your device.
Before flashing the new rom, you should make sure that the kernel is compatible with the one that is already on your device. If it isn't compatible, you will also want to flash the new kernel using fastboot/flashtool, and not recovery. Also make sure you have a back up of your rom's current kernel so you can flash the original kernel, if you decide to go backwards.

Thanks I think that what im looking for.. the Nandriod backup..
gota way to find that now and how to install
Thanks a lot!
Hmmm...the most easiest way it to unlock your bootloader first...then flash custom kernel...this can help you skip rooting and installing recovery again and again if something goes wrong cause all custom kernel is pre-rooted and got recovery by default....
next you need to find which custom roms you want to flash...some custom roms have their own kernel or flash any custom kernel that is compatible with the roms....
remember, custom kernel is important cause if you flash the wrong kernel, you might get bootloop after flashing the roms....

[Q] Want to update Ginger2.3.4 to JB4.3 [facing issues]

Respect members,
I recently decided to upgrade by Samsung Galaxy S2 GT-I9100 from default 2.3.4 to "PACMAN Custom Rom" which looked amazing to me. I haven't USB cable so after a bit search, i found "Framaroot" and rooted by mobile. I have downloaded the "PACMAN Rom" but the only problem i have is that i am unable to flash "CWM recovery" without USB. Is there any solution? And if Once i flash "CWM recovery". Should i install "Dorimanx Kernel" as suggested by "bluefa1con" ? Dorimanx Kernel in its thread clearly states that you shouldn't flash the kernel if you are using GingerBread. Then how should i update? Should i just let the PACMAN Rom use the Stock Kernel.
Please don't mind if it seems kiddish because i am completely new to this.
Your Help is Appreciated.
You can flash cwm recovery without usb, you just need to find to correct package and flash it via stock recovery, i think you will need JB bootloader too tho. But, i don't recommend first time flashing without a USB cable, if something goes wrong you can't use odin to go back, so just borrow one or buy one, they aren't expensive, and you can flash JB stock via odin and then flash a custom rom, that would be better imo.
Either use the appropriate CF kernel to root and install CWM, or upgrade to JB/ICS using Odin and flash Siyah/Philz kernel. Then, once u have CWM recovery, flash your desired custom 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!

[ROOT] Can someone help me, please?

Hello everyone. First of all I need to emphasize that I'm currently in an english couse so if you find some mistakes in my writing, you'll know why.
The reason I'm here today asking for your help is that I recently bought a second hand SGS3 and the volume up doesn't work and I want to enjoy my phone the way it has to be enjoyed, so i've been searching how can I reboot the phone into recovery mode via cmd, and I did it, but now I need to know how can i root my phone with the stock recovery, because I can't find nothing that use that stock recovery, all is with odin or a different recovery, I've seen that philz recovery it's installed via stock R or something like that, but I don't know which version to install. I have an S3 I9300 with 4.3
You can use a USB jig to force the phone into download mode and then flash cfautoroot with Odin.
You need download mode to root. Once in download mode you need to flash chainfire autoroot (i9300 version) via odin on a pc, then you can flash an official clockwork recoverymod recovery to your phone via odin. Reboot the phone and your done.
Beamed in by telepathy.
Another way to do this is to flash another OS like CyanogenMod via Odin.
But at first you'll have to convert the CyanogenMod installer zip to a file that can be flashed via Odin. CyanogenMod allows you to reboot to recovery directly from the OS using the reboot menu that's built in.
