How to Upgrade iPhone 3gS & iPhone 4 to Custom 4.3.1 Firmware Preserving your baseband

[Jwwwow]

does this work with a jailbroken iphone 3GS?? because my carrier is tmobile.

[Chazzos]

great video. Does anyone know how I can fix my Iphone 3g? Its stuck on the boot logo for 5 minutes then the "download circle" shows up on the lower part of the apple symbol. Then the phone restarts its self and the process starts over again until the battery dies. My computer will not register the Iphone but it will register other Iphones. I do not get a option in my computer under the hardware>device manager section. Iphone will charge but no charge symbol shows up.

I have an iPhone 3GS with 4.2.1. I followed your instructions to the point of hitting Shit+Restore, browsed the Custom 4.3.1 ipsw file. iTunes begins to extract the software and after that an error window pops up that says: iPhone cannot be restored. unkown error (3194). What can I do now? My phone still is in DFU mode...

alert 3194 help

[irqusa79]

I have Iphone 3gs, and its running on 4.0.2 and baseband 05.13.04. is there any way for me to upgrade to 4.3.3 or any latest versions? thank you!

[filmwerk]

Seems, that the issue of preserving 3rd party applications plus data of these apps, not to forget notes/calendar/addressbook, are never really addressed. Though I appreciate your insight and videos, I do need to ask the questions, if - while enjoying the new iOS on both phones - I would have to re-install all apps of my JB+unlocked iPhone 3G + 3GS and especially how to make sure not to lose all of these apps (currently 124) during the upgrading process. MANY THANKS in advance!

[rafaeybuksh]

dude will i loose all my data?

[eastazn]

thanks broo working great for me

[CODofficer]

@eastazn will all the apps be restored

[kashim12341]

great video just a few questions for clarity

1. i am in the uk and my iphone is unlocked to any network will your video affect this

2. will it still be usable in the uk

[KurdsNL]

[CityofSeoul]

Hi Emac, I have a 3gs on 4.0 and i would like to upgrade it. Will following these steps preserve my baseband? (05.13.04) I don't want the ipad baseband. I noticed you only mentioned 3gs with the ipad baseband. Will this custom firmware update my baseband to the ipad one?

[IVIaiko]

Best fuckin' turtorial in youtube. I was stuck in iphone 3gs 4.0 for over a year. Thank you, kudos

[martincoolkid]

is the jailbreak tethered or untethered

[kittennveyron]

I messed up sorry i meant can i follow this video if i have a 3gs on 4.2.1 with a baseband of 05.13??? Because i followed ur other video

[kittennveyron]

Is it ok to do if u have a iphone 3gs runing in 4.0.1 on 05.16??

[iJbreak]

I followed all the steps and when i go to restore from itunes after its done loading the prepare to restore it says "The iPhone 'iPhone' could not be restored. An unknown error occurred (1600). PLEASE HELP

[emac2299]

@iJbreak Download 'TinyUmbrella' . Save your SHSH through tinyumbrella. You will see the versions for which your SHSH blobs are saved. You can only custom restore to those versions that you see inside TinyUmbrella.

[iJbreak]

@emac2299 i did so and it saved iPhone 3g 4.2.1 (8c148). Now i am using the proper firmwares from your 4.2.1 video i'm just using this as a tutorial on the steps.

[rattleadi]

Boss I've 4.3 iPhone 4 which is subscribed to AT&T network... Is there any ways I can factory unlock or carrier unlock it rather? Pls help

[emac2299]

@rattleadi Factory Unlock will cost you a fortune ($180). But you can still do a Hardware Unlock by using a 'Gevey Sim' available at Applenberry(dot)com. If you are located in UK then buy this sim from 'Rebel'

[wizkidosa]

hey does ultra snow unlock. 3.10.01



[Jtawehsat]

I followed all the step and I got an error 3194. I even did the HOST thing in itunes. I'm still getting error 3194. Doesn't matter which itune version you have. I tried 10.2 and then 9.2 and got the same result. now my phone is stuck in pwnd dfu mode and wont wake. Any help?

[xxZR2xx]

i have an iphone 3gs on 4.0.1 unlocked, with baseband 05.13.04. can i use this to unlock it with your custom firmware

[AVIALV]

WoW!! It worked!! thanks!! At first I didn't want to do it beacause I haven't seen this information of these steps in pages like DevTeam of iClarified and then you don't show the outcome of these steps in your video, but anyways, I followed the same exact steps you described and used your download links and now I am on 4.3.1 FW and kept my 01.59.00 baseband.. Thanks for this video dude!!

[iJbreak]

PLEASE HELP! i went through all the steps and when i get to the itunes part it say that there is a compatibility error.

[404Trucho]

Oh and I'm not an unlocker or anything I jus don't wanna lose my ish

[404Trucho]

@emac2299 if I wanna update my iPhone 4 without losing anything should I update by doing this method? Or does it not matter?

[bryansifsof44]

[hayetg]

Hi i am a previous unlocker and i decided to watch your video and now i cannot use my phone. I followed all the steps but I have no WIFI so I cannot install ultrasnow from Cydia on my phone. Is there an alternate solution currently for firmware 4.3.1???

[trisen101]

ok dude i have a 3gs on 4.3.1 firmware, 05.16.02 baseband that is jailbroken not unlocked... is the dev team working on a unlock for this baseband (05.16.02)? if so when will it be ready? if not what steps will be the best for me to unlock my phone for T-Mobile? i dont want to get stuck on a baseband (06.15.00)! What are my options? Please Help!

[trisen101]

[andysalamsari]

Hey question if i do this meathod to go to 4.3.1 will it fix the gps on it ? cuase i have it jaibroken on 4.2.1 6.15.00 baseband so i was wondering if it would fix that ?

[BuhaloSoldier]

Hey emac!

Will redsn0w unlock 03.10.01 bb on 4.3.1 firmware?

[anirban17aug]

I have 4.2.1 with bb 03.01.10. So do you think that i should upgrade to 4.3.1? What should i do???

[afgrules09]

Okay i did everything you showed me but the cydia app wont open it just closes right away, HELP ME PLEASE :) thank you

[ChallengeLobbyyz]

You can unlock 4.3.1 with ultrasnow now, first install ultrasnow then add the repo djayb6.com and install the ultrasnow unlock fixer. Then you will be unlocked and jailbroken on 4.3.1

[williamta01]

@ChallengeLobbyyz Thanks, works very well.

[thomasandrigo]

@Ronald .. Go into Cydia and download "ztoggle" there you will enable multitasking &wallpapers.

[ronaldguinhawa]

hi thanks..is there multitasking gesture?thanks

[emac2299]

@ronaldguinhawa For full Multitasking gesture on iPad you will have to use newly released Snowbreeze. 

[voteboo]

hey, emac. You're good buddy. Thanks for sharing. I was hesitant with the upgrade from 5.16(base...) runing on 3.1.3, but everything went just fine. One question i do have for you is that you mentioned some issues with the custom firmware 4.3.1 that are currently happening. Can you tell us what are some of those "bugs"??? I just undated my device so I wanna be aware of them before they(bugs) show themselves.

Thanks again man.

[emac2299]

@voteboo If you are an Unlocker then 'Ultrasn0w' on 4.3/4.3.1 will have some issues till DevTeam fixes it. It should be done very shortly.

[voteboo]

@emac2299 Yeah, I just came across these "issues".The phone isn't able to pick and cellular signal at all, I tried all the instructions given by you on the other vid you uploaded today, and nothing so far. The only thing I am able to see on my phone is, hear actually, the voicemail notification sound. I was wondering if you got a video where you show how to downgrade/upgrade an iphone 3gs and up but preserving the baseband?I want to get a custom 4.2 to avoid a baseband undesirable "upgrade".

[BIGGSiPhone]

the custom firmware will work even if im on 03.10.11 r what ever it is

[emac2299]

@BIGGSiPhone Custom firmware works with everything. They always preserve your iPhone's baseband.
