If I'm rooted and I install rom manager and it Installs clockwork recovery do I need to install it the way in this thread to flash a custom rom or am I good.

hmmm, im confused a little. on the stock touchwiz rom i was seeing the LTE icon, and under CM9 im not seeing it at all.. thats why im pretty sure that rogers has me on an LTE plan (or that its activated) does CM9 display an LTE icon? so far, all I see is '3G' or 'H' with speeds of about 5Mbit

could this be a modem issue?

EDIT: i noticed that when i add the APN in the OP, the phone doesnt use it. if the default is available, it uses that : rogers-core-appl1.apn... probably why i cant get LTE on this network... :/

Cm is set for att icons, so lte would be 4g, Rogers uses 4g for 3g connectivity and lte for lte.

Set up the apn in the op, select it, and delete all other apns. You should then be on lte if you are using Rogers.

thank you very much for the clarification david, very much appreciated. i had deleted all other default apns and put the APN in the OP on its own, but couldnt select it. everytime i would, it would just go deslected automatically. but ive done it now, and ive got a 4g icon with some better speeds. im gonna test this out and see how it goes

thanks again man, really helpful. im not getting a minimum of 12Mbits where i am, more like 6-7, but im on the 30th floor of a downtown building that never gets good reception.

Yea the lstrst cwm doesn't support external sd you have two options you can flash the cwm version 5.8.4.5 or twrp which is fully touch and much simpler recovery to use, you can find it under development forum here
Edit-actually the newest cwm does i didn't realize it because u use twrp :eek:

hey guys, i got my s3 yesterday, followed this guide (thanks a lot by the way) and flashed CM9 nightly (2012-08-16) and one think i notice is that 3G / LTE seems considerably slower than on stock rom... i created a new APN with the settings listed in the OP and it seems the same. anyone seeing the same drop? stock ran speedtest.net at around 5-6 Mbit and now with CM9 im getting 1-2 Mbit... what do you guys think?

thanks :)

Yeah sounds like you don't have an LTE plan. You should be getting 20MB+ down. If you do not see a 4G symbol beside the signal bars, you're not hitting LTE. Also make sure you go into the mobile network settings and switch it to "LTE / WCDMA/ GSM", the GSM only mode will NOT get you 4G.

Will flashing a rom through recovery trip the flash counter after all the steps in this guide? Thanks

I have a question. How do I get the stock recovery back on gs3? I have a rogers one if its helpful. I was thinking I can just flash the pre rooted ROM to get the recovery then just delete the superuser apk then I'm unrooted. Is this correct? Thank you

You can flash a normal back to stock image. This will delete and remove all data and put it back to complete stock.

    People worked hard to get this where it is now but I had to search through a BUNCH of different posts to find the proper recovery images, files, etc. Thought I would put everything here so it takes a shorter amount of time to get it done:

    *NOTE: UPDATED, THIS IS FOR ALL 747 MODELS, JUST GET THE RIGHT ROOTED ROM FOR YOUR CARRIER BELOW*

    To Root The Galaxy S3 (Rogers SGH-I747M Model & Others) - And Use a Custom Rom If You Wish


    1. Download Odin 3.07+ and the Samsung S3 Drivers here:

    http://xdaforums.com/showthread.php?t=1722686


    2. Download the LATEST clockwork Recovery Image Here:

    http://www.clockworkmod.com/rommanager

    D2ATT Galaxy S3


    3. Download the stock ROM: http://xdaforums.com/showthread.php?t=1739426

    Extract it with WinRar/7Zip.


    Now for the easy part... seriously lol. How to ROOT:


    1. Make sure phone is charged.

    2. Install the Samsung USB Drivers with the phone disconnected.

    3. With the phone booted to Android. Plug in the phone. Once the drivers install, disconnect the phone.

    4. Power off the phone.

    5. Put the phone in Download mode: (Hold volume down + home button, then press and hold power until download mode comes up. Then press the volume up key to continue).

    6. Connect the phone to the computer again.

    7. Wait for more drivers to install if need be.

    8. Open "Odin3_v3.07+".

    9. Only things that should be checked in Odin are: Auto Reboot and F. Reset Time.

    10. Press the PDA button. Load the extracted Pre-Rooted Rogers Rom (or pre-rooted rom for your carrier). Flashing this ROM should not delete any data on the phone.

    11. Once the ROM is loaded (it may take a minute or two), hit the Start button in Odin. DO NOT DISCONNECT THE PHONE.

    12. Once the phone reboots you are DONE! The phone is now rooted with the stock software. You will have superuser etc. Do NOT update superuser within superuser itself. It breaks it/does not update properly in my experience.

    Note: If you are coming back from another ROM to Stock, please make sure you wipe and format all partitions on your phone, then go through the above steps. Failing to do so will make your phone hang at the Samsung boot screen. If you are experiencing this, just boot into the stock recovery and wipe, then reboot.



    To Flash ClockworkMod Recovery:


    Have the recovery image on the internal memory...name as "recovery.img"


    Download Android Terminal Emulator from the Play Store, have the recovery image on the internal memory, run:

    Once in the terminal type: su (press enter)
    Then type: dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18 (press enter)



    Once the recovery is flashed, you can load Cyanogenmod 10+ from here:


    http://download.cyanogenmod.org/?device=d2att&type=nightly


    Newest Rogers/Bell/Telus modem/radio image (ATT is located here as well):

    Yeah should work, but I have no way to test it.

    Download the rooted image for bell here (telus listed as well for those on telus): http://xdaforums.com/showthread.php?t=1739426

    ***Not sure if the ClockworkMod recovery for ATT will work on bell (although I dont see why i wont and you can always flash back to stock if need be) but give it a go and let us know haha***

    If it doesnt work, the above link has the recovery for Bell.

    AT&T, Rogers, Bell, Telus and Sasktel are all on the i747 version of the GS3. The differences (that I am aware of) between AT&T and the Canadian carriers are the modem (software that connects the phone to networks such as cellular/wifi/bluetooth) and carrier bloatware or restrictions. As mentioned above by Ka24e, make sure you use your carrier's rooted image if following this guide to root. Other than that, if something works on Rogers, I cannot see a reason why it wouldn't work for the Canadian carriers mentioned above.

    The only thing I strongly recommend AGAINST flashing is an AT&T modem....this could brick your phone!

    What's the difference between the CWM recovery you posted (5.8.4.5) and this one? http://www.epiccm.org/2012/06/cwm-recovery-on-all-sgs3-lte-variants.html :confused:
    Click to expand...
    Click to collapse

    Team Epic's cwm recovery is actually for Sprint, but should work well on all devices (I used that one before switching to twrp recovery here).

    The one posted in the OP is the AT&T cwm recovery, which many developers insist be used as a condition for support on their roms. If you are going with CWM, I would suggest the ATT version above for that reason.
