Iphone 4S error -1 solution stuck with problem new ios

On March 29, 2015, Posted by , In iPhone, With Comments Off on Iphone 4S error -1 solution stuck with problem new ios

Hi!


I have here Iphone 4S Along with strange problem. The story goes like this:
I have bought Iphone 4S Along with -1 error , phone is like new never water damaged. Last owner say that this phone worked good and he wanted to put latest IOS 6.1.3 and have error -1. I try all things here mentioned on forum like few batteries, cables, dock cables, few computers, rehot BB… and always error -1.It just go fine until goes to updating iphone firmware (BB) and error -1.
For now just forget on this phone for a while.

I also have one motherboard from Iphone 4S Along with updating problem. But on this one I can not even start to flash. In iTunes is preparing iphone and after that error 1603 or 1611. kindly dont tell me that this is problem Along with my computer, host file or something similar ( I repair Iphones almost every day) because I already try that. But there is something strange on display when I start to flash, the picture of screen is in attachment. It just freeze there.
I decide to use this motherboard like donor for repairing other iPhones so it is not important to repir it. It is only important to know what kind of error it have.

Now we are going back to first phone. I started to measure/repairing it but didnt find any problem. As I have donor motherboard i try to change U18_RF (some people say here that this can make error -1 ( I didnt measeure first VREG_MSME)) and not to believe now this phone that have error -1 dont want to even start updating and errors 1603 or 1611. I put his originaly U18_RF back (also try Along with connected pin 2 and 4) but same thing error 1603 or 1611 (first time when I connect it will be 1611 and after 1603). Offcourse same screen like donor motherboard…

I put logs from 1603 and 1611 if someone can tell me where to look for a problem kindly do.

Thanks in advance

Best regards

    How did you check U1001_RF friend? Do you have BATT_VCC_FET?
    How much heat did you use when replacing U18_RF?

    I think your original problem could have been solved Along with a reball of the baseband PMU.

    I think errors 1611, 1603 are serious problems especially when getting stuck on that screen means NAND may be faulty, can not be read. Try reball NAND but not sure sensitive A5 still will be good after

    Salam
    I find this solution but I did not test for this problem

    Hmmm, I believe these errors are related to the ram stack of the A5? So if this chip has a bad solder ball, or the powerlines (hence the PMU) are bad, one would see a 1603/1606/1611/ect. error.
    Checking the buck-outs from the PMU will reveal if the PMU wants reball, or if the A5 top-stack wants reball.
    Anyways I dont think this has anything Along with the NAND flash chip to do.

    check this component near camera flash bos.. maybe can to be helped you last time i solve problem like that first i try to change u1001_rf but still same then i check mother board then i see some component fualty near that location.. thanks

    atatssssss

    @jegerjon
    I checked BATT_VCC_FET when this phone have error -1 and it was OK
    I use normal temperature like I do every day.
    I will check those four voltages later and inform.

    @all
    this phone looks like new I even didnt remove any emi shield exept one on BB when i was reflowing BB trying to repair -1.
    And after reflowing of BB it flashed until BB update then -1
    Problem Along with freezing screen and errors 1603 and 1611 came after puting U18_RF from donor board which also have errors 1611 and 1603????
    Strange???

    Im checking board Along with microscope but everything looks fine.

    can i ask something that phone is from your *******r? did you ask about what happen before bringing to you? maybe that could to be helped you to diagnose the problem.. before what is the issue camera working fine ? or the flash of the camera working fine also. or something. . did you try to restore Along with out LCD?.

  11. ExpertBuddy says:

    Yes i have try to restore only bare motherboard Along with battery and dock flat cable.
    I purchase that phone Along with -1 error and trying to repair it. Now have 1611 and 1603.
    It gives me -1 until i changed U18_RF, after that 1611 and 1603.

    This is what I would do: first reball PMIC, check if you are back to error -1. If you are, then check the voltage lines BATT_VCC_FET, VREG_MSME and BB_HSIC_RDY. Also check resistance to ground from the VBAT_GSM line.
    If all the above things are good, then you must reball BB PMU and BB flash (start Along with the BB PMU), and I give you 95% chance that your phone is back on track 🙂

    i got the same problem …, it happened while updating to IOS 6.1.3 …….,

    try to fix it in redsn0w , but same… rehot/reball the PMU and colcoum processor .. but same ///
