Error (-1) Iphone Restore
Nicodemo Aidara
An unknown error occurred (-1) when trying to restore an iphone 7. My problem with my phone was that I had a no service issue, could not receive or send text messages or calls. Only had the phone 6 months and it has no damage. Before I tried to restore it I could get on the internet on my phone and see all the apps and everything on it, but now that I tried to restore it, the phone is frozen on the restore screen. I sent it in to the apple repair store and they sent it back saying they could not repair it, no other explanation. Only that they could not duplicate the issue, whatever that means. Now I am told to send it back in again for another look.
My error message was (-1). I tried 1,2,3,and 4. I also contacted apple support and was on the phone with them twice for over an hour each time, with each representative asking me to do the same steps over and over again. I even tried to restore the iphone on a different computer with the same results. I was told by the apple store that the no service issue was a known defect on the iphone 7 and it would be under warranty but I had to send it in first. The first time I sent it in they sent it back saying that they could not duplicate the problem, probably because as of now the phone is frozen, so of course they can't see the "no service" issue I had with it.
Yes, I did send the phone in for the second time but I haven't heard anything yet from them. I'm afraid i will be out the almost $300 I paid for it (it was pre-owned) cause I didn't buy the insurance. I will update when I find out their answer.
i have an iphone 5s and I was updating it with iTunes and it was half way across and I got error code -1 and now iPhone is stuck in recovery mode and wont get out tried other computers still dint worked cnt even find a solution online for the error code -1plz help (note: iTunes is on latest version ,I downloaded the ipsw directly from iTunes no tird party software used new iPhone , iPhone is currently on ios 10.3.1 and wont upgrade to 10.3.2 stuck)
Pretty sure -1 is a hardware error. Anyways, you're there now. I would put the phone into dfu, and restore the phone. Whatever hasn't been saved, is lost now. You can restore to a backup, either through the cloud, or iTunes
ITunes error -1 is baseband firmware failure to load. It is the eeprom ic failing to communicate with the modem hardware issue 100% either cracked ball on the modem data line or damaged eeprom. You will have to take it to a capable technician with eeprom programming equipment.
do you mean you might have this damaged hardware in your phone, and not know it, if all you have been doing is updating occasionally....but then, if you decide to restore/recover....THAT'S when the issue makes itself known....?
My daugher had an issue while trying to update her 5c at home connected to an iMac via wifi, and decided to fully erase the phone first/restore mode (there was nothing really she cared about on it yet, she'd just gotten it).....and when it got to the firmware part, it got stuck and gave an Error 48 message. I tried a recovery myself, on another computer, a PC, and get Error -1! But both times it just stops there, mid-recover....and so the iPhone is useless, it can't do anything, it has that picture of the lightning cable pointing towards the iTunes logo perpetually onscreen!!
*Please note if you follow this method of fixing an iPhone stuck in recovery mode, all the data and settings on the iPhone will be erased before restoration. Your device will be restored to your last iTunes backup. However there is a way to recover deleted data directly from your iPhone when this happens. This way you will be able to recover data obtained since your last iTunes backup.
Make sure you have the latest version of iTunes. To do this, open iTunes and click Help in the main menu. Then select Check for Updates, iTunes will then tell you if you are using the latest version. You may need to download the latest iTunes version before you continue.
Hold the home button down (on the front of your iPhone) and connect the device to your laptop/PC while iTunes is open. A message should pop up and say that your iPhone is in recovery mode and needs to be restored.
When I connect my iPhone 5 to iTunes, it gets stuck at the iTunes logo. When I try to restore or recover, it goes fine till around 60%. Then it tells me, "iPhone could not be restored unknown error 1." My phone has never been jailbroken. Also, I couldn't get it into DFU mode. Please help.
i just fix the problem error 1 on iphone5c, and it is simple!!gow here and download the latest ios for iphone is very simple it shows everything there just put your device iphone 5c 5s 6 any one..sorry a bout me english guys! after you have download the latest ios on your computer gow to i tunes and push the buton( shift ) and restore..it works fine for me
This does work it must be some solder problem, I heated it up but not as long as 5 minutes just for about a minute with a hairdryer over the SIM card slot , then used a can of air to blast any excess away and plugged it into iTunes started getting a few new errors but that may of been because it was still warm, all worked in the end though thank you and good luck :-)

Thanks Vlad, the heating with a hairdryer on the back lefthand side and sim tray area for approx 5 mins (until casing was nearly too hot to touch) and 2 X restores worked for me too. Didn't need to open and clean it.
hi guy it is good news for those who having problem with their iPhone while restore or update and getting constantly errors like on windows (-1 ) and mac you will get error 3 and while device is connected to your computer the progressive bar will freeze at 60 to 75 percent and the respective message will pop up on windows and Mac. I am very much exhausted trying to get rid of this errors but no luck, even I have applied all method of apple websites as well as try from you tube help but no chance. I am a engineer myself of different trade but I very fond of these latest electronic gadgets.
lets start the work .1 first make sure your device is on and apple logo or ITunes player connected appear on the device screen , take you device and put in plastic bag and please make sure no water enter inside the device through bag, it might damaged your hardware. Than place the device in the freezer for 45 to 60 minutes, Meantime keep your computer ready to connect your device with good USB cable. Removed the iPhone and connect immediately to the computer and massage begin to display extracting software it will progress slowly wait till end .Even you device might get disconnected while in progress don't worry ,let the progressive bar get end and message comes your device is not found .than you unplug it from computer and plug it again than procedure will continue till your phone is restore and new latest firmware is installed ,during the progress your phone will shows progressive bar on screen wait till further message you get successful Good luck
note : the real problem is that the firmware not extracting properly that is why phone can not be restore or update that is why hardware need to be frozen ,it need certain temperature ,because software is not responding to the hardware to get extract and install. It will not install room temperature or atmospheric ambient temperature.
IT WORKED!! I didn't believe it would work, but I had nothing to loose. I put the phone in the freezer for 50 minutes, connected to iTunes, and finally it restored the phone. I tried 10 times before with different cables and computers and it got stuck every time with an error code 50 - unknown error, and could not restore. THANK YOU!
i tried the same thing.. put the phone in the freezer for 40 minutes, removed it and plugged it directly to the computer.. the progress bar on the screen stops at 75% and gives me an error 50 on the computer, same as before. after that nothing happens. What do I do? please help as this is driving me crazy!!
Just had a quote to fix this issue of 535, so bought a new one for 300 from a friend. The issue is apparently a firmware problem/hardware fault. I have been trying to get to the bottom of this for the last month or so and even complained to Apple and have had no real explanation of what the problem is, or if it can be fixed. mine was out of warranty, so no replacement either. I see some other fixes on here and will give them a go, but think this is pretty much terminal.
I have fixed it with a DFU restore before. I usually had that error when the IPSW wasn't being signed anymore by apple. I had to download the latest IPSW from a third party site, one that didn't have my SHSH blobs attached to the IPSW before it would work.
I'd say from reading all this that error 1 is a hardware problem caused by dry solder joints somewhere in the phone. Heating up the phone will basically improve the solder joints. This is risky though as you could also make other joints worse.
Ok guys, error -1 is an error where your baseband can't connect to the cpu. For those who don't know, there is a big brain (cpu) for the majority of the phone and a little brain (baseband cpu) just for the cell network. Typically the problem is caused by a cracked solder joint somewhere due to a drop or jolt. When you heat or cool anything on this earth, it changes in size ever so slightly. Heat expands the object and cooling shrinks it. So either way you go you are shifting the chip ever so slightly and the micro crack touches again and you get a working device. However once it returns to normal temp the crack will reappear. The most obvious spot to crack is under the baseband cpu or the big cpu. This is because the solder contacts are the smallest on the phone here and have very little yield strength to resist a jolt or drop. If Apple didn't use underfill (a water proofing black tar) on the chips you could just throw it in a reflow oven to fix, but they do. The only correct fix therefore is to remove and reball the baseband cpu! This is the hardest thing to do next to reballing the main cpu and only a handful of techs can accomplish it. If you do use the oven, you will prob lose network eventually and the next restore will be a repeat. If the baseband cpu went bad then you have to pull the trinity from a broken phone and put it on yours. If you don't know what that is, then you will never be able to do it anyways ;) If you are a tech and do decide to reball it, clean the tar around the contacts with a needle. The board contacts rip off easy because they are so small.
