Izasao za iPhone 3G/3GS 6.15.00 Baseband Downgrade

[stolex]

1. Preuzmite trenutni iOS koji je instaliran na vasem iUredjaju, to mozete odavde

2. Preuzmite Redsn0w 0.9.14b1

3. Raspakujte i pokrenite Redsn0w 0.9.14b1, ukoliko zatrazi, dozvolite mu Administratorske privilegije

4. Izaberite Extras/Select IPSW i potrazite i izaberite preuzeti iOS fajl iz prvog koraka, pa Open, pa OK

5. Kada vas pita, recite da li imate stariju ili noviju verziju iPhone-a 3GS (da li imate new ili old bootrom)

6. Izaberite Back pa Jailbreak, Redsn0w će sada da radi

7. Stiklirajte Downgrade from iPad baseband, ako imate Cydia-ju vec instaliranu, odstiklirajte je, pa Next

8. Ubacite telefon u DFU mod u sledećem koraku

9. Redsn0w ce ponovo da obavi svoj posao i da vas obavesti kada proces bude gotov

Ostatak procesa se desava na iPhone-u i posle nekog teksta i ikonice ananasa ispisace se tekst Flashing Baseband koji traje dugo (3 - 8 minuta) tako da nemojte da panicite


Kada se proces zavrsi, iPhone ce se reboot-ovati i imaćete baseband 05.13.04 na kome radi GPS i koji moze da se otkljuca softverski, ukoliko nije SIM free.

Na ovom site-u imate i detaljno upustvo sve sa slikama How To Downgrade iPhone3GS 6.15 Baseband Using Redsn0w.

P. S. Nekad trebate par puta da pokusate da biste uspeli. Inace upustvo je preuzeto sa drugog foruma...

Pokusaj, nista ne gubis. Dosta njih je povratilo svoj telefon na normalan BB i to bez problema...


Dodao bih jos ovo ako nekima ne uspe prema onom upustvu. To sam isto tamo izvukao sa tog foruma.


OK, so redsn0w was released yesterday that will downgrade iPad baseband 6.15.00 to 5.13.04 but it didn’t work for some. Here’s the fix which you can try.

I tried to downgrade it while the iPhone 3GS was running on iOS 5.1.1. When the process was completed, the phone booted up but it was still showing iPad baseband 6.15.00. I found a simple solution which hopefully would work for you as well.
Firstly, use this iPad baseband downgrade guide I posted yesterday. Once done, if you still have baseband 6.15.00, try the following:
1. Build custom iOS 4.1 either with redsn0w or sn0wbreeze. You can also download custom iOS 4.1 for 3GS or you can use any custom iOS 4.x for iPhone 3G since it doesn’t require SHSH signing.
2. Put iPhone into pawn DFU either with iREB or redsn0w.
3. Launch iTunes and press Shift+Restore (Windows) or Option+Restore (Mac). Since Apple is still signing iOS 4.1 for iPhone 3GS, make sure your hosts file doesn’t point to Cydia server (though it’s OK if you have SHHS for iOS 4.1 saved there).
4. Wait until the restore is complete.
5. When your iPhone reboots, you should see your baseband is now downgraded to 5.13.04.
6. You can then build a new custom iOS 5.1.1 with sn0wbreeze or redsn0w to preserve the baseband, restore it and then unlock with ultrasn0w 1.2.7.
Pretty strange but this would work for sure.[/QUOTE]
