Die you try formatting everything including internal sdcard?

Do you have an international SIII without a simlock? Or was your SIII shipped with a simlock in the first place?
If you have a verzion SIII try this:

Ive done a clean rom install through philz cwm - im assuming this is the same as a clean install?
Im based in the uk so doubt I have a verizon model.
Thanks

You say any that presumes you have tried them all .
In recovery format sdcard system data cache boot to download mode flash stock rom or boot to recovery and flash your custom rom .
Really you should start by reading the faqs and guides first .

Hi,
Sorry for being so brief.
I have formatted sd card through mounts and storage and cache
Done a clean ROM wipe also.
Still no custom rom appears to boot - all stock roms flash fine through Odin. Restores of stock ROM are also working fine..

Then you are doing something wrong .
Start with a stock cwm rom .

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] Carbon Rom, can't get rid of it!

Hi
I'm new to rooting /Rom's. I've tried to flash different Rom's, but now I've got stuck with a broken Carbon Rom. I've re-flashed, wipe data tried known working Rom's, but it keeps re-starting Carbon Rom!
I have tried to seek the problem, and how to delete this Rom, but I can't find anything about that.....
I've got Samsung Galaxy S3 I9300
Plz help ^o^ :crying:
Make sure you have a new Rom on sd card, then format system and data in recovery, then flash Rom or use Odin to flash stock firmware

[Q] Installed Custom ROM, boots into stock ROM

Probably a dumb question on here but I couldn`t find it in searches..
I recently rooted my galaxy S3 and installed S4 revolution custom ROM. However after the installation it boots into what looks like a stock ROM.
The S4 ROM is supposed to be Android 4.2.2 but the ROM that is booted is 4.1.2. I installed it by copying it to the external card and putting the phone into recovery mode, I wiped cache and did a factory reset before I installed.
Can someone explain why it doesn`t boot into the new ROM and what I need to do?
Then you have not installed custom rom.
Go back to the rom and read and understand the instructions .
Multiple reasons why it failed user error the norm bad file wrong format less likely .
Use failed to install CWM recover is another .
Basics read first.

[Q] My i9305 think it's a i9300 after formatting

Greetings fellow Earthicans!
I've been roaming these forums for several years now and have been able to fulfill all my custom rom needs by searching, trial and error. I've bricked all my phones at least once but have always managed to make the phone work better than when i first stardet modding it. This time i managed to do something i've never been able to do before and i'm therefor writing my first post here.
Yesterday i did a full wipe/format of everything available in CWM because the internal phone memory was close to full. In the process i managed to erase all my backups, which i thought was fine since i loaded my external sd with most of the custom roms and gapps available on this amazing forum.
However, when i tried to flash either one of the .zip files i get the same message "this package is for "m3", m3xxm i9305, gt - i9305 device; this is a "m0"." Even though i've had both avatar and miui ROM installed a few hour earlier. I was stuck on the boot screen, as so many other times with this and other devices.
So i searched around this forum and google and found out that m0 is the i9300 and my initial thought was "nice, perhaps i can install the custom roms of the i9300 by copying them to my ext sd and install through CWM" Which of course did not work and i realized i had to go back to stock through the download screen
So i downloaded my firmware (4.1.2 and 4.3) from sammobile.com to do a stock reset through odin 3.07. Both firmwares works fine and all of the phones functions work as intended, as far as i know.
I'm currently running 4.3 I9305XXUEMKC_I9305TLAEML1_I9305XXUEMK1_HOME.tar.md5 without any problem, but would love to be able to run custom ROMs again, but have no clue how to proceed.
I would be eternally thankful if someone know the solution to this problem i've encountered through my irresponsible actions.

This is not i9305 q&a .
in recovery format system sdcard data and cache then boot to download mode and flash the correct stock rom for your phone via Odin .

Thank you for your reply.
I've checked which of the stock rom to use and have done as you described, i can run the stock rom and currently am.
iIve rooted the phone and installed CWM through odin. When booting into CWM, and clearing as described in all guides, i still get the same error message given in my post above.
are you sure you do have the right recovery and that this is up to date?

[Q] Help: Bootloop after upgrading CWM

Hi all,
For backup purpose :angel:, I tried to upgrade to the latest Recovery_CWM_6.0.4.7_I9100.zip using Install Zip from an older CWM of my Samsung Galaxy S2.
And I'm in big trouble because after installing the clockworkmod recovery the phone won't boot anymore. It's stuck on "Galaxy SII - GT-I9100 - SAMSUNG" splash screen :crying:
The CWM works and gives this log:
I:Can't partition non mmcblk device: /devices/platform/dw_mmc//mmc_host/mmc0/mmc0
I can mount partition and accessed it from my pc.
I wiped cache and dalvic cache without more luck.
There is no vibration on boot either.
As my data aren't backup yet, I don't want to wip them out with some ROM. Did I miss something?
Any hint about what I should do to have the phone boot again would be greatly appreciated! :highfive:
Cheers
@GalaxyS2u did you flashed the right cwm/kernel for your rom since they are included in one boot.img? If you cannot flash an new rom anymore in the recovery or reflash the kernel /recovery then you need to flash an kernel/recovery in odin. Try an odin philz kernel if there is one else flash siyahkernel with odin.
And that partition thing is that even an valid partition ?
Backup your data first in recovery then try my things i suggested. I still think that the reason why it doesnt boot is because you flashed the wrong recovery/kernel.
Are you on stock btw? I suggest to try to flash philz kernel if you are on stock.
@wulsic
Thanks a lot for your hint :good:. That saves my precious! :victory:
I can manage to come back to my old CWM recovery with a flash of siyah with odin.
The new CWM works only with a new ROM and not with my old stock. With this experience, I am even able to upgrade to the KitKat version.
Viva this model and this community!
@GalaxyS2u glad to hear you figured it out I also had that problem when i flashed S2 first i soon found out that kernel/recovery were in one happy flashing?
