Hey folks. I'm not entirely new to ROM flashing. I've been flashing numerous ROMs on my Diamond, TouchPro2, and Desire. The actual steps and tools are different but the basic principle remain the same. It's just wipe and flash.
But on the SGS2, the process is getting on my nerves. If I simply do a wipe and flash, I ALWAYS get boot loops. I always have to go through the following steps:
1. Wipe and flash stock ROM via ODIN
2. Flash CF-Root via ODIN
3. Boot the device to the setup wizard.
4. Flash "abc" ROM via CWM or ODIN
Is this actually what all you SGS2 ROM flashing veterans do? Or am I doing something wrong?
Also if I'm on a custom ROM, I can't even do a hard reset without encountering boot loops. I'd have to go through those 4 steps again. It's driving me insane...
Don't wipe through recovery. Format through settings.

This doesn't seem to work either. I was just on Lightning ROM and I did a hard reset by going to "Settings > Privacy". That resulted in boot loops...
As of this moment, I just can't seem to figure out how to flash ROMs or hard reset without being at my PC. Does everybody else always rely on their PC for their ROM flashing needs?
Hmm...something seems wrong here. Here is what I do and normally don't have any issues.
1. Reboot into recovery.
2. Wipe data/factory reset.
3. Wipe dalvik cache.
4. Format system.
5. Install the downloaded rom from sdcard OR go to download mode and flash thru odin depending on zip file or odin file.

For a clean phone i format phone through windows . In recovery format system data and sd card .
Should be no problems left on phone .
Install stock rom via Odin followed by cwm and root copy custom rom to sd card and flash .

I know how to get out of bootloops. The question is, how do I flash ROMs without the PC (ie, without having to flash back to stock rom via Odin)?

The instructions for the rom may require you to have a stock rom or not depends upon what the rom builder decides .Some require custom through Odin other via CWM.Most are CWM flashes and do not mention stock rom at all .

Before or After the rom's zip installation (flashing) do you wipe data/chace factory reset + wipe cache + advanced and wipe dalvik cache?
mostly because of corrupted download

Hi
I have a SGSII (i9100) which I have successfully rooted (all "permission" files work ok through Superuser). However, I don't seem to be able to install Clockworkmod or, if successful, then I can't boot normally.
When I try to install CWM via Odin3, it installs ok, but the phone then hangs on the triangle screen. I can boot into the CWM screen where it tells me that it cannot mount to system nor to the cache. Any attempt to reboot normally fails (i.e. it hangs on the triangle screen). Thanks to a kind member helping me, I have been able to recover each time by using the I9100XXKI3.ZIP package.
I have also downloaded Rom Manager and tried to flash CWM from there. That says that it has been successfull, but when I then boot to the recovery, it tells me that "E:failed to verify whole-file signature and e:signature verification failed". Consequently, no CWM, just the usual recovery screen.
Am I missing something? Can someone help, please? At the moment I have root, but can't install any custom roms.
Thanks, masterpointer
Try to flash kernel with cwm. That should do it
Sent from my sgs2 running cm9 using xda app
First thing rom manager is not compatible will the sgs2, second thing it's confusing when you say you restore a .zip as this is done via cwm? In order to get recovery via odin you need to be using an appropriate rooting kernel. When you did manage to get into cwm did you wipe cache and delvik etc?

Download cf root kernel and flash with odin, and you`ll have cwm recovery. Don`t use rom manager with sgs2, never.

I did use an appropriate kernel. I wiped neither the cache nor the delvic cache before flashing, and after flashing I can't as the message says: "e:failure to mount \system" and several massages "e:falure to mount \cache\..."

I take your point regarding Rom Manager. but that aside, I have flashed CWM via Odin3 onto a rooted kernel and it does install, but phone hangs (freezes) on the triangle screen. I have tried several versions of CWM an several rooted kernels. They all install and they all freeze!

Boot in recovery, mount and storage, format system, data,cache. Pull battery out, after 2 min put it back, boot in download mode, start odin, flash stock rom, reboot, reboot again in download mode, then root with cf root kernel. Should solve you problem

I don't have "mount & storage" in recovery. Only Reboot System, Apply update from SD card, wipe data/factory reset and wipe cache partition.

You need to install a cwm rooted kernel .
Root + CWM .

yes, but therein lies the problem:
After I use cf-root (with KI4 kernel), the phone hangs (despite Odin3 showing everything ok)! And when i then boot into recovery, it says "e:failure to mount \system" and several massages "e:falure to mount \cache\..." and attempts to "mount" the listed items, all fail.

Thanks for your help, but as I said previously, I was unable to do any of your suggestions because as soon as I installed CWM, I was unable to mount the system and the cache.
However, since then I did some further research and came across a forum where several others had the same problem and one of them tried to use "Speedmod-kernel-s2-k2-21-Odin.tar" and, lo and behold, that worked for me as well!!!
I'd really appreciate some help guys, I've searched everywhere but can't seem to find answers.
I had Cyanogen Mod 9 rooted on my phone, however, I decided to install Omega instead, I installed it but I can't get on it! Everytime I install zip and reboot, it goes back to CWM Recovery!
The procedure was:
-deleted all files in internal SD
-Reboot into CWM Recovery
-Wipe data,cache,dalvik
-install zip from sd card
and now im stuck
Please help, and apologies if any noob mistakes were made

You'll lose all your data but do a factory reset and wipe your system in addition to what you've already done and re flash the rom. FYI always have a nandroid backup around before flashing. It's time consuming but saves you a lot of grief in the long run

Factory reset(wipe) is an option in cwm(3rd from above) wipe and reflash the rom and let it boot,this can take 10min
1st check md5 .. it will show u wether its bad download or nt ... and then do this
go into cwm and to wipe data\factory reset wipe cache wipe dalvik and insll rom ..
omega 10 is up so better try omega 10 as its new rom :

Factory reset is on the main Cwm screen. You can wipe system through the 'mounts and storage' option

How would put it into my internal SD if I can't transfer the file because I can only boot into Recovery or Download mode? Do I just Odin it straight in via the PDA option?
If you connect your phone with the PC while in recovery you should be able to use adb commands
Put the rom file into the adb folder than try
Code:
adb devices
now you should see any cryptic combination of letters and numbers in the next row
(if you see a empty row... that wouldn't be nice^^)
then do:
Code:
adb push yourromfile.zip /sdcard/yourromfile.zip
than try flashing again the new file
dont forget to do a full wipe, cache wipe, dalvik wipe, the common procedure^^
PS:
If you don't know about adb, it is installed with the android sdk, but you can download it seperately
place the ADB folder somewhere on you system hd, maybe directly to C:\
the open cmd and type
cd C:\ADB\
now you're able to use the above commands
You can put it on an external sd and flash it from there...

Thank you, all of you... I will try this tomorrow and tell you guys how it goes!
Thank you so much EVERYONE, It all worked out, seems like the original file was corrupted, now running omega 10 smoothly!!!!!!!
If I do a full wipe including the system partition I am given to understand that I have bricked the device if I reboot. Obviously there will be no operating system to boot into, but will I be able to get into download mode or CWM?
Thanks.
Full wipe is followed by flash firmware via Odin or via recovery if the file is on Ext SD card .

YES!!! if you reboot after full wipe you can still go into download/recovery mode!
But, you don't need to reboot after a full wipe, just install the new rom after the wipe and then reboot.
Was that clear?

Not clear at all as above only applies to a flashable zip custom rom via CWM recovery not to a stock rom that requires booting to download mode and flashing via Odin .

Yes, that is why I'm asking. CWM not an issue as I would already be in it after the wipe. To get into download mode requires a reboot.

hi there i have had my device rooted for awhile now and all of the sudden it just started to get stuck in a bootloop, just displaying the "samsung galaxy s III GT-I9300T" screen then goes black and repeats
i have a sgs3 GT-I9300T (from telstra, australia if it matters)
i rooted with "CF-Auto-Root" which worked fine and was working fine for atleast a month
i dont have a backup (yes im a noob/idiot for not creating a backup but didnt think there was any reason to)
i have tried flashing the latest firmware from sammobile using odin (with only auto reboot and F. reset time checked)
i can still access recovery (factory or custom from flashing in odin)
i've already tried a few suggestions from some posts on here but alot of them arent for the international/I9300T version so wasnt game enough to try them out in fear of fully bricking it
if anyone can help out with what i should try that would be great
i would even settle for resetting flash counter and system status back to 0/offical so that i can try and return it
current state is:
Custom binary download: Yes (3 counts)
Current binary: Samsung Official
System status: Custom
Did you try factory reset from recovery before/after reflashing stock?

yes and even installed CWM recovery to clear the "dalvik cache"
Here is thought
Pull out sdcard, better format in FAT32, copy few ROM into it by using card reader or other usable phone which has sdcard slot.
Flash any of newest recovery such as TWRP personally suggested, Backup current ROM in case of further needed and then
Factory reset, format /system partition, wipe cache / Dalvik cache, and then flash new ROM too see if it works.
Remember format system partition!

download this file http://checkrom.com/threads/resurrection-odin-checkrom-evohd™-v4.896/
get into odin and flash this file into your phone through the download mode ... if everything works it should boot into cwm recovery .. then wipe data\factory reset , wipe cache , wipe dalvik cache and reboot ... wait 15 mins and it should work!! Good Luck!
woot this worked!
i tried re downloading the file first like qtwrk suggested and reflashing it in odin which still returned the same result but i then downloaded this one and did it and it worked
i got into the os downloaded triangle away and reset the counter then flashed the telstra one again so that it was right back to factory default firmware which is what i wanted, will proberly root it again but will def make sure i get a full backup right away incase of any issues later on.
thank you all for your help
hye me again just thought id write an update on my situation
it appears that the phone had stuffed up again this time tho couldnt get into recovery mode but could still get into download mode
i didnt bother doing the same thing again instead i just took it back to telstra and they replaced it, and they replaced it with the 305 model so worked out alright in the end
