Iphone 4s Bad ESN Unlock: Learn How to Sell Your Blacklisted Phone



I'm buying a unlocked iPhone 4s from craigslist tomorrow. I just need to know how I can verify if it is unlocked. I have an old AT&T sim card I used to use for my iPhone 4. Not sure if that would work.


If it is a phone that was purchased locked to a carrier and then officially unlocked the only way to tell is to do a factory restore in iTunes and see if it displays the "This iPhone is unlocked" message afterwards.




Iphone 4s Bad Esn Unlock




I have an iPhone 4s from Pioneer Wireless that I need to have unlocked because it has a bad ESN on Pioneer Wireless. Is there a way I could unlock it and if so how? I believe that Pioneer Wireless won't unlock their phones, so is there some other way I could get it unlocked?


Thanks for the help. I called Pioneer Wireless and gave them the IMEI and the MEID and they said that the iPhone was not eligible for an unlock. So as of now I guess the iPhone is rendered useless as a phone. Since it has a bad ESN the only way I could have used it was to change networks, so now I guess I'll just either use it like an iPod, sell it, or wait for some other way to unlock it in the future.


Your iPhone might be locked to your carrier. Unlocking your iPhone means that you can use it with different carriers. To contact your carrier and unlock your iPhone, use these steps. You can find out if your iPhone is locked by going to Settings > General > About. If "No SIM restrictions" appears next to Carrier Lock, your iPhone is unlocked.


On what part of the iPhone 5 is the Apple ID information stored? I want to know what chip or part to remove in order to would remove all info about Apple ID (to get past the iCloud Lock). Would changing the Logic board (from an iPhone without the lock) remove the problem? Is there any other way to unlock such an iPhone? Thank you!


If your phone is locked you either have a stolen phone or someone who has access to your account has locked your phone. At this point you'll need to go to the Apple Store with iron clad proof you are the owner of the phone for them to unlock it. Otherwise you should return the phone to the rightful owner.


I asked because I wa thinking to buy one of those very cheap iPhone 5's from ebay that are locked from iCloud. My idea was to buy one that's locked and another unlocked logic board. Put it in and have working iPhone 5 for very little money. + I clould get one that's from verizon and has bad ESN(even cheaper) and use it here in Europe on GSM. Do you think changing logic board would fix problem?


You should re-read what I said - I stated it was likely a stolen phone not that all locked phones are stolen as I also stated someone who had access to the account could lock your phone and I suppose if you fail to pay Apple for your iCloud account you will loose access to it as well. But that doesn't lock your phone only the server account and the access to the data on the server. Your friend has either twisted things around or has another problem. Your friend will need to visit Apple with phone in hand with proof he or she is the owner of the phone for them to unlock it. As for the eBay phones you can't prove you owned them so they are of little value as a phone. If they were stolen (most likely) you would have bought nothing but trouble.


I agree, 50$ for a not locked, functioning iphone 5 logic board is suspicious as !@#$. In China the trend is around 2000 CNY which is more than 300$. Even with that price, nobody guarantees the board is not taken from replaced phones or registered with icloud. Anything cheaper than that probably gets you into trouble


Yes very possible in fact did it today. If its your first time working on an iphone, here is a little hint I wish someone told me 3 years ago. GET A PAIR OF 3X READING GLASSES from the dollar store. It will save you so much grief.


Get an unlocked iPhone and then get another locked iPhone, solder the unlocked chips off locked one and re-solder them on the unlocked one, now get other chips off unlocked iPhone and solder them on locked iPhone, WAIT.


Magic solution, pick up unlocked iPhone in left hand and now concentrate as this is very difficult part, pick up locked iPhone in right hand, put contents of left hand in right hand and contents of right hand in left hand now in left hand you have locked iPhone and in right hand you have unlocked iPhone.


One locked imperfect condition one that's inlocked got ran overthe original plan was to swap screens but once you get th open and screens removed you see a lot of differences even the battery's are different voltage and what not. The one is locked because it was lost. Can you swap parts over and what are needed to be swapped. Also I just want to add to the really dumb peranoid comments above. Apple does not have iPhone police nor will they ever. .Really this find phone function is pretty useless other than you can temporarily disable the phone. So I want to keep the parts that the screen plugs into on locked phone but everything to the home button I want gone and retro fit the unlocked phones parts that are different slightly but different non the less into the locked one thus making it nice shiny new and functional. Don't say I can't because I'm gonna just looking for some advice. I'm not techy I'm just a tile setter so if I'm doing this I know someone else has had to have done it. Thanks in advance now go!


I have iphone 5s clean without icloud.. but first its on red screen then i flashed it then it stucked on itunes logo and itunes error 4013.. and i also know the solution is that remove nand and reprogram it.. but my question is that if i replace the nand flash only from other unlock phone that will work or not??


Okay, so I have an iPhone 4s locked to Verizon/CDMA on ios 5.1.1. I am trying to unlock it to GSM, but everything I have tried to achieve unlocked status has failed (Jailbreak unlock using SAM, factory unlock). Is there any way I could perform a hardware mod and remove the CDMA processor and replace it with a GSM processor? Or, are the two so different that it would most likely not fit or recognize it? Any assistance in this would be appreciated.


I appreciate your speedy response but have a couple questions/clarifying facts to add. First of all I've browsed many different forums and it seems that there is no definitive, clear answer. Most people are saying that even with an unlock, I still would not be able to use this on either AT&T or T-Mobile, it would only gain service outside the US. That is also my concern with the Gevey sim, although I have just brushed the surface of research into Gevey I feel it would just unlock it for outside US service. I am also not a verizon customer and am most likely not on good terms with them as I bought this phone off craigslist and I believe it was stolen/lost as it has a bad esn on it.


The GSM side of the device is locked by the service provider to block it from using domestic GSM networks (such as AT&T or T-Mobile). Locked, at the firmware level and can't be unlocked. Almost all of Sprint's and Verizon phones are locked in this manner to prevent you from using them on other networks.


In my experience I have not seen anyone successful with either Verizon or Sprint get the GSM part of their device unlocked and working properly on AT&T or T-mobile. It couldn't hurt to contact Verizon and see if they have ability to unlock an iPhone 4S and the GSM side of the device, however it won't work. : / (Sorry.)


Keep in mind that the Verizon iPhone 5, 5C, 5S, 6 and 6+ are unlocked from the factory and will work without any additional unlocking steps. The Sprint 5, 5C, 5S, 6 and 6+ are all locked and need to be unlocked or flashed.


I have an iPhone 5 purchased from Sprint about September of 2014. Now, because of over charges and no solution to the problem I stopped Sprint service and changed to Consumer Cellular, but they have an incompatible service and Sprint indicates that they can't unlock their own phone, but gave me a MSL code that they indicate Consumer Cellular can use. But, Consumer Cellular indicates that due to the operating incompatibility between CDMA (Sprint) and GSM (Consumer Cellular), I best go to Apple Store and see if they can alter "something in my iPhone" to make it GSM compatible. I don't know what "flashed" means. But, I suppose it means hook my iPhone 5 to a "wire" and have it reprogrammed in some way. Can anyone tell me if an iPhone 5 bought in the autumn of 2014 can be "flashed" to GSM. Sprint indicates they cannot unlock it!!! even if they sold me the phone.


You can replace the baseband processor but it is extremely difficult and does not make economical sense. The only way to genuinely unlock an iPhone 4s is to go through the official carrier unlock process.


As we have seen above it is not that hard to unlock your device so go ahead and unlock your iPhone and enjoy the benefits of an unlocked device be sure to check first of the device is unlocked or not. You can easily do that by inserting a SIM card from a different carrier. If it works, the device is unlocked. Let us know if you experience any problems with the method above.
