This EEPROM Chip Programmer Can Fix iTunes Error (-1), 3, 6, 16, 47, 48, 1669

When restoring your iPhone on iTunes and if you’re getting Error (-1), (3), (6), (16), (47), (48), (1669), this chip programmer is able to fix it.


I hate doing a full restore of any iDevice because it can be unpredictable and you may get one of the following errors which are usually related to hardware issues or specifically the chip(s) on the mainboard (logic board) of the iPhone or iPad:

  • iTunes Error (-1)
  • iTunes Error 3
  • iTunes Error 6
  • iTunes Error 16i
  • iTunes Error 47
  • iTunes Error 48
  • iTunes Error 1669

What Do These iTunes Errors Mean?

All of these errors are related to the the EEPROM chip. EEPROM is short for for electrically erasable programmable read-only memory.


The contents of the chip are made up of data whereby  they can be erased and reprogrammed using a pulsed voltage.

If for any reason the data is not stored or written properly, it will cause error especially during the process of restore on iTunes.

Another possible reason if the device was accidentally immersed in liquid or water which causes short circuit thus may cause similar errors.

Some people reported that other hardware issue like broken antenna will also contribute to these errors.

How to Fix these iTunes Errors?

As a general rule, some of these errors can be fixed simply by doing a series of steps on your iPhone (or iPad) and iTunes.

Before you begin, do make sure your data has been backed-up and you have a spare phone to use just in case.

  1. Launch iTunes and connect your iPhone
  2. Put your iPhone into DFU mode – press Power and Home Button for 10 seconds, and then release Power Button but keep holding the Home button for 5 seconds.
  3. The screen will stay dark but you will see a message on iTunes that your device is in recovery mode.
  4. Click Restore.
  5. The process to restore will take a while so wait until it completes.

If the restore goes smoothly as planned, that means your device doesn’t have any hardware issue.

How to Fix these iTunes Errors by using a Chip Programmer?

A company in China developed a device that allows qualified technicians to fix these iTunes errors.

They claimed that it will support all models of iPhones from iPhone 4S up until iPhone 6S Plus.

As the logic board of an iPhone is highly delicate and sensitive, removing any chip will cause permanent and irreversible damage.

Therefore this device allows you to fix iTunes error without having to remove any single chip from the logic board.

Technicians only need to connect the logic board to the device, but we didn’t get to see in details on how it’s done.

The chip programmer is also able to erase, read, re-write, check and diagnose EEPROM chips and of course to fix iTunes Error (-1), 3, 6, 16, 47, 48, 1669.

For an advanced repair centre, this is probably a tool technicians need as there are not many repair centres which are specialised in fixing errors like these.

Normally the logic board is replaced right away.

This device sounds very promising and will definitely save a lot of broken iPhones out there.

We hope we can get to try this soon and post the results here.

Do You Know the 4 Types of Carrier Unlock for Sprint iPhones?

There are 4 different types of carrier or IMEI unlocking available for Sprint. Do you know what they are?

All of us want to have options in life. If we get an iPhone locked to a certain carrier, we want to get it unlocked so that we can switch carrier or to be able to use it overseas.

Sprint iPhones and like other iPhones from other US carriers such as AT&T or T-Mobile, are locked when purchased. Verizon devices on the other hand are usually already unlocked for other network.

This article basically explains the 4 types of unlocking services available for Sprint if you’re thinking about getting yours unlocked.

Here are the 4 types of unlocking available for Sprint iPhones:

1. Unlocking for Sprint iPhones with Clean Status

This is the simplest and cheapest available option to unlock your Sprint iPhone. Clean status means the iPhone has clean record or in other words clean ESN. It also means the iPhone has good standing on the Sprint database and not blacklisted.

If you run a check on a clean Sprint iPhone on the Sprint database, it will return the following result:

IMEI: 35328907xxxx103


Model Number: IP6SP16GBRS1

Manufacturer: APPLE, INC



If you notice the Blacklist Status shows that it’s clean.

The speed to unlock is also fast by carrier because of its clean status. The unlock for clean Sprint iPhone is available here.

2. Unlocking for Sprint iPhones with Active Line

Active Line means the device is active on another customer’s account. This is not very common but it’s still possible to unlock it without any issue.

The check on Sprint database will show the following:

IMEI: 3533360738xxxxx


Model Number: IP6SPBT16GY1

Manufacturer: APPLE, INC



The unlocking option for Sprint Active Line iPhone is the same as clean status.

3. Unlocking for Sprint iPhones with Unpaid Bills

This is probably the most common status for Sprint iPhones. Sprint customers didn’t pay the bills after signing up for Sprint’s mobile plans.

IMEI: 3533120740xxxxx


Model Number: IPH6S128GSV1

Manufacturer: APPLE, INC



Unpaid bills Sprint iPhones can be unlocked relatively easy except the price is slightly higher compared to clean status. The only thing to note is the SPCS status as shown above. If the status is YES, you can use this service to unlock it. If NO, then you will need to see (4) below.

4. Unlocking for Sprint iPhones that’s Fraud, Reported Lost or Stolen 

Thousands of devices are lost or stolen each year in the United States. This status is also quite common. It shows the following result on Sprint database:

IMEI: 3591270776xxxxx


Manufacturer: APPLE, INC



There are also fraud status which usually means people are using some other people’s information or credit card etc. to purchase the phone. If marked lost or stolen, the iPhone is normally marked as blacklisted on all US network or carriers.

It can still be unlocked but only for use outside of USA. This is the premium service you need to unlock it. Any unlock for Sprint that’s lost, stolen or blacklisted is called premium service.

Those are the 4 types of unlocking services available for Sprint iPhones. Besides unlocking, you can also consider to unbar your Sprint iPhone.

Before buying any Sprint iPhone that you plan to unlock, it’s highly recommended that you check the status first by providing the IMEI. The IMEI can be found under Settings, General, About.

How to Clean Bad ESN/IMEI for Lost or Stolen Sprint iPhone

If you mistakenly bought a used Sprint iPhone that’s blacklisted due to lost or stolen, there is a way to fix it remotely.


One of the risks of buying a used iPhone is that it may have been reported lost or stolen. Especially if you didn’t check the status prior to making the purchase.

The device will be blocked by its network or blacklisted on all network in the country.

Here are some of other reasons why they get blocked:

  • Unpaid bills
  • Insurance claims
  • Fraud

On Sprint’s database, once a device has been blocked, it will show the status like the following:


SPCS is short for Sprint Personal Communications Service.

What else can you do with a device that’s blocked or blacklisted on the network? Well, here are some possible options:

  • Unlock the device
  • Sell the device

If you choose to unlock the device, as long as it’s not blocked on other network, you can use it on Verizon, AT&T or T-Mobile (USA network).

However, if it’s blocked on all network, you can still unlock it but you may not be able to use it in USA.That’s still not the end though, because there are options for you to fix the ESN/IMEI of Sprint remotely.

Fixing the ESN/IMEI remotely would mean “cleaning” it on the network. Once it has been cleaned, other carriers will update their databases as well which makes it possible for you to use on all network for as long as the device is unlocked as mentioned earlier.

If it has unpaid bills status, it can be cleared as well.

If you wish to consider cleaning it, please refer to this service here [Clean/Clear Sprint iPhone, iPad or Android with Bad ESN (MEID)].

Can You Fix the ESN/IMEI of Sprint iPhone with Unpaid Bills?

If you accidentally bought a used Sprint iPhone with unpaid bills, can you change the status from unpaid bills to clean?

The best thing about buying a used device is getting a good price of it. However, it has a lot of drawbacks because potentially the device may be blocked by its network or blacklisted on all network.

Here are some of the reasons why they get blocked:

  • Unpaid bills
  • Lost
  • Stolen
  • Reported missing
  • Insurance claims

On Sprint’s database, once a device has been blocked, it will show the status like the following:


SPCS is short for Sprint Personal Communications Service.

What else can you do with a device that’s blocked or blacklisted on the network? Well, here are some possible options:

  • Unlock the device
  • Sell the device
If you choose to unlock the device, as long as it’s not blocked on other network, you can use it on Verizon, AT&T or T-Mobile (USA network). However, if it’s blocked on all network, you can still unlock it but you may not be able to use it in USA.

That’s still not the end though, because there are options for you to fix the ESN/IMEI of Sprint remotely.

Fixing the ESN/IMEI remotely would mean “cleaning” it on the network. Once it has been cleaned, other carriers will update their databases as well which makes it possible for you to use on all network for as long as the device is unlocked as mentioned earlier.

13 Things You Can Do with a Blacklisted or Stolen iPhone

Bought a really cheap iPhone recently but later found out that it’s stolen or blacklisted? Don’t worry, one of these 13 tips may be able to help you.

The first thing you found out when you got your iPhone is that it’s not getting any signal from your carrier, or that probably happened a few days after your purchase.

You’re pretty sure that there’s no hardware issue but after spending hours online looking for a solution or explanation, you finally found out that it’s been blacklisted by your network provider.

A few years back, I wrote a blog post about ‘What Ever Happens to IMEI Blacklisted iPhones or Other Popular Smartphones?

This will help you understand more on why your iPhone got blacklisted in the first place.

It may feel that it’s the end of the world. Don’t worry because someone out there had gone through what you’re feeling right now.

Let’s get things straight and check out these helpful tips. Do note that some of the advice below are only valid if the iPhone is not stuck on the iCloud activation screen.

1. Ask for a refund from your seller

This may be a long shot, but if you bought it used on eBay, you can ask for a refund from the seller by following the refund procedures set by eBay. You will have to arrange to have it shipped back to the seller, once he or she confirms that the iPhone is in order, eBay will release the funds back to your account.

The case may be different if you got your blacklisted iPhone over on Craigslist or on the street.

It may be difficult to get your money back because these types of sellers probably won’t entertain your calls at all. They may use a temporary email address and will no longer respond to your email.

2. Use it as a glorified iPod or games console

Since you can’t make calls with your iPhone, just use it as an iPod or install as many games as you can to keep you entertained for hours.

You can also download movies and TV series on it which you can watch while on the subway or hanging out in the park.

3. Get the ESN or IMEI Cleaned

There’s a bit of a good news if you have a blacklisted iPhone that’s locked to Verizon, Sprint, T-Mobile (UK), Orange (UK) and EE (UK).

It’s possible to remove them from blacklist (fix for blacklisted iPhone).

Unfortunately, many other network are still not supported.

The services we provided are highly reliable and have helped many people to use their iPhone again. You might also want to know that these services are not limited for iPhone only, any device such as iPad or Android smartphone can only also be removed from network blacklist.

Click on the link below to learn more:

If the device – iPhone, iPad WiFi, Apple Watch (iWatch), iPod has iCloud lock on it, you can also remove it by one of the method below:

4. Swap the Logic Board

Since IMEI blacklist is usually localized to a country’s particular service provider, that means your iPhone’s IMEI is not blacklisted in other countries.

For instance, if you have a factory unlocked AT&T iPhone that’s blacklisted in the USA, if you travel to Australia it will work perfectly on any network there.

There isn’t a way to change the IMEI of an iPhone except by physically replacing the baseband and CPU chips; and this is only possible on iPhone 4 and earlier models.

Attempting to change the chips on the latest models of iPhones will only cause damage to your iPhone. This is the reason why swapping the logic board is quite a practical solution.

5. Get it officially unlocked and sell it

There’s still a market for your blacklisted iPhone.

If you live in the USA, you know that there are millions of foreigners coming to your country especially students. When they finish their studies, mostly would return to their home countries.

This is where your iPhone becomes valuable. If you have an AT&T iPhone that’s already officially unlocked but blacklisted, you can sell it off to them.

They always want to find good deals while they’re there and even though it’s blacklisted in the USA, it can still be used in other countries.

A lot of people get good deals when buying AT&T or T-Mobile iPhone 6 or iPhone 6 Plus online, but they ended up buying blacklisted iPhones.

However, AT&TT-Mobile or Sprint iPhone 6/6+ and later models that are blacklisted can still be unlocked. Please be sure to tell them the whole truth about the history of the phone to avoid any complication later.

Remember that honesty is the best policy. So do explain to your potential buyer that the iPhone is blacklisted in your current location but will work fine in his or her country. Don’t forget to checkout other network that we can officially unlock.

6. Sell it as spare parts

If all fails, your last resort would be taking it apart and cannibalize it for parts.

The screen, logic board, back casing, dock connector can all be sold separately. It may help someone with a broken iPhone and one of the parts may help revive his or her iPhone again.

It’s not the most ideal but you might doing other people a big favor while getting back some of your hard earned cash.

Consider yourself lucky if you bumped into this post while trying to find a used iPhone. The blog post I wrote about 5 Tips on Buying Used iPhone Online on eBay or Craigslist to Avoid Scam will help you prevent all these from happening.

7. Donate it to Charity

Some charities recycle old electronics and may offer cash.

Consider Googling for it and do something nice for someone out there.

8. Sell it on eBay internationally

eBay is a huge global marketplace and someone out there will want to buy your iPhone despite the condition it’s in now.

Please do mention in the eBay ad of the real situation to avoid the buyer from creating a dispute which may cost you even more.

9. Start your own iPhone repair business

Wait, what?

Yup! This is how most mobile phone stores started. They take it apart, learn how to put them together and offer the services to people.

10. Contact the Owner, Carrier or Authority

Some stolen or missing iPhone will have the original owner’s number shown on the activation screen. It may be worthwhile to contact the owner and have it returned. You never know how thankful he or she might be.

Calling a carrier is also possible to track down the original owner. They may need the 15-digit IMEI of the device.

Reporting to authority may help too.

11. Get the iCloud Email

If the phone is stuck on activation, it will hint the email address on the screen. Although it’s not always possible to guess the correct email, you can use this service to get the full email address.

Once you get the full email address, then refer to point #10.

12. Make a YouTube video of smashing it to pieces

Shooting a YouTube video of smashing the phone can make someone really famous.

Checkout on YouTube to get some inspiration.

13. Keep It

If none of the above fancies you, just keep the phone as a remembrance.

Somehow it can be an expensive lesson. Perhaps one day you may want to revisit one of the solutions above and may even work for you!

I hope this article is useful for you. Do you have anything else to add? Otherwise, please do help share this with your friends!
