Question about Samsung SYNC SGH-A707 Cellular Phone

1 Answer

Big problems in Brazil!

Hi,

I bought this phone about a year ago, with the idea of using it to travel with. I'll spare the past episodes, but when I arrived here in Rio de Janeiro, Brazil about 5 days ago, I went directly to a reputable place to buy a local SIM chip, since I'd had my phone unlocked before leaving the States. The carrier is called Vivo, and after they installed the chip, my phone saw the network and listed it (Vivo) on the main screen.

Everything was going well. I was able to make and receive local calls, which is exactly what I wanted to do. The only thing I was having trouble with was the Voice Mail (or Caixa Postal as they call it here). They told me I had to wait a few days and then it would activate. (Sounds strange, but Brazil's a unique place.

Then, all of a sudden this morning, I get a message whenever I try to use the phone that says "Emergency calls only" in English. The carrier Viva is no longer listed on the main screen, and I'm unable to make or receive any calls at all. When people call me, they are sent immediately to Voice Mail, which of course, I can't access.

I'm going to be down here for a month, and I absolutely need to be reachable. Can ANYONE help me with this? I would be forever in their debt. Thanks for any advice,

Nela

Hi i write hear because i have a big problems! I used this guide an...


This will guide you on activating, jailbreaking and unlocking your iDevice & thus will be of 2 parts: Part 1 - Jailbreak with redsn0w; & Part 2 Unlocking with ultrasn0w.

Hardware compatibility:
  1. UNTETHERED JAILBREAK - iOS 4.2.1, 4.1, 4.0.2, 4.0.1 and 4.0
    • iPhone 3G
    • iPhone 3GS old bootrom
    • iPod touch 2G non-MC model kid_ant_5.png
  2. TETHERED JAILBREAK (?) - iOS 4.2.1 ONLY - you can use either greenpois0n or sn0wbreeze for untethered jailbreak, for these iDevices:
    • iPhone 3GS new bootrom
    • iPhone 4
    • iPod touch 2G MC model
    • iPod touch 3G
    • iPod touch 4G
    • iPad kid_ant_5.png
  3. UNLOCK - iOS 3.0 up to 4.2.1
    • iPhone 3G
    • iPhone 3GS old bootromkid_ant_5.png
  4. UNLOCK - iOS 3.0 up to 4.0.2 ONLY
    • iPhone 3GS new bootrom
    • iPhone 4
Not sure if your iPhone 3GS has old or new bootrom? CLICK HERE. Or if your iPod touch is MC or non-MC? CLICK HERE.

Compatible basebands (BB) for ultrasn0w 1.2.2:
  • 06.15.00 - iOS 3.2.2 from iPad (read further for details)
  • 05.13.04 / 01.59.00 - iOS 4.0.2, 4.0.1 & 4.0
  • 05.12.01 - iOS 3.1.3
  • 05.11.07 - iOS 3.1 & 3.1.2
  • 04.26.08 - iOS 3.0
Notice that BB 05.14.02 & 05.15.04 are NOT part of the list. You need to update these BB to 06.15.00 for ultrasn0w unlock to work. Read further for more info.

However, if your BB is 05.13.04 or lower, you can proceed with jailbreaking but make sure you DO NOT INSTALL THE IPAD BASEBAND.

WARNING: Read the following consequences of updating BB to 06.15.00:
  1. There is no way to come back down from 06.15, & there's no hiding the baseband version from Apple. You'll be voiding your warranty in a very obvious way. kid_ant_5.png
  2. If some future baseband comes out with a critical fix, you won't be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn't update to it if you wanted to keep your unlock anyway). kid_ant_5.png
  3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won't ever be able to restore to stock firmware (it will fail). You'll need to only restore to custom IPSWs (then again, if you're unlocker you should already be doing that).
DO NOT PROCEED if you don't agree.

What you need: NOTE: Download iPad's 3.2.2 IPSW ONLY if you'll use PwnageTool. Also, download ONLY the IPSW for your current iOS version. CLICK HERE if you have no idea what version is installed on your iDevice, especially if it's currently disabled.

For jailbreaking other iOS versions like 4.3.2, use other versions of redsn0w. CLICK HERE to see the list of all redsn0w versions.

Procedures:

PART 1 - JAILBREAKING with redsn0w (all iDevices):
  1. Connect your iDevice to the computer, run redsn0w & click Browse kid_ant_5.pngkid_ant_57.jpgkid_ant_5.png
  2. Locate IPSW for your current iOS, select it & click Open kid_ant_5.pngkid_ant_58.jpgkid_ant_5.png
  3. Wait until it say IPSW successfully identified. Click Next kid_ant_5.png
  4. If you plan to unlock your iPhone 3G / 3GS old bootrom, you need to check Install iPad baseband to update BB to 06.15.00 kid_ant_5.pngClick Yes if you're OK with these consequences:kid_ant_5.pngkid_ant_60.jpgkid_ant_5.pngAgain, you only need this option if your BB is either 05.14.02 or 05.15.04. This will result to updating your BB to 06.15.00 which can be unlocked using ultrasn0w. kid_ant_5.pngAlso, if your BB is 05.13.04 or lower, this jailbreak will still work for your iPhone but make sure you DO NOT INSTALL THE IPAD BB! You don't need it! kid_ant_5.pngFor iPod touch users, the BB thing does not apply for you. so you have nothing to worry about.kid_ant_5.png
  5. Choose some more options before you click Next kid_ant_5.pngkid_ant_61.jpgkid_ant_5.png
  6. Turn OFF your iDevice & prepare to put it to DFU mode then click Next kid_ant_5.pngkid_ant_62.jpgkid_ant_5.png
  7. DFU mode: Press & hold the POWER button for 3 seconds kid_ant_5.pngkid_ant_63.jpgkid_ant_5.png
  8. DFU mode: Press & hold HOME button while still holding on the POWER button for 10seckid_ant_5.pngkid_ant_64.jpgkid_ant_5.png
  9. DFU mode: Release the POWER button but keep holding on the HOME button for another 15 seconds or until you see Jailbreaking... on redsn0w kid_ant_5.pngkid_ant_65.jpgkid_ant_5.png
  10. Wait until it tells you that The rest of the process takes place on your iDevice. Click Finish kid_ant_5.pngThat will take around 8 to 9 minutes to complete
Once the jailbreak is done, open your iDevice & you'll find Cydia on the 2nd page of your homescreen.

PART 2 - UNLOCKING with ultrasn0w (iPhone ONLY):kid_ant_5.png
  1. Open Cydiakid_ant_5.pngDon't worry if Cydia's icon is blank/all-white, it will still work. kid_ant_5.pngThe first time you open Cydia, this is what you'll see (image below), then it will close itself and take you back to the homescreenkid_ant_5.pngkid_ant_66.jpgkid_ant_5.png
  2. Open Cydia again. Before you proceed with the unlock, go to Changes first and do a Complete Upgrade kid_ant_5.png
  3. Tap Reboot Device after the upgrade kid_ant_5.png
  4. After reboot, you can then unlock. Open Cydia again (for the third time), and tap the following (in sequence):
    • Manage
    • Sources
    • repo666.ultrasn0w.com
    • ulrasn0w kid_ant_5.png
  5. Tap Install, then tap Confirm kid_ant_5.png
  6. And finally, tap Reboot Device
And you're all done! Your iPhone should catch signal after the reboot.

I have a Quickfire GTX75 sold and configured to AT&T. But I traveled to Brazil and I'll stay here for a few months. I can only send messages and make calls. GPS, Internet, Bluetooth, everything...


Bluetooth should work fine, just pair it with your headset or hands free.

Make sure it's unlocked. GPS and internet require data, so make sure you buy a SIM card with data on it. Many SIM cards only have voice (minutes).

Good luck!
