    Patch Cert

    The first reasonable question is why IMEI repair or Patch CERT functions are needed?
    Why Restore CERT is essential?
    To answer these questions, here is some streamlined background information about how the phones work software-wise.
    Common knowledge that every phone has a serial number (IMEI). Basically, this is a digital data that gets connected to the given phone during manufacturing and it also gets signed by the manufacturer (this is the so-called Certificate). This certificate includes, among others, a certain data of the IMEI and, in case of new models, an ID code of the given phone to prevent the re-use of the certificate in a different phone. Practically, this make it impossible to clone an IMEI number. This certificate cannot be reproduced since solely the manufacturer owns the private key to create it. The certificate is being checked by the modem. The integrity of the modem is controlled by other peripheries at lower levels. Conclusively, the input of the IMEI or other certificates is not enough since the modem will not accept it.
    This system is quite secure up to the point when the IMEI or the certificate is damaged. We do not want to go into details on how an IMEI or certificate can get damaged but the damage is mostly caused by an intervention of a software or flash error.
    What is important here is when the IMEI or the digital signature is damaged, the phone is not working and even Samsung service centers cannot repair the broken phone. Thus, the phone is worthless at that point.

    The most common errors that might suggest such a problem with the phone are the following:

    • The IMEI number consists of only zeros: 000000000000000
    • When dialing *#0011#, the IMEI status is NG and the network data are all wrong.
    • A call cannot be made and the phone’s status is ‘not registered to network’ so practically, the phone cannot be used at all.

    This is the point when our newest innovative solution gets into the focus since it is generally provide solution for such a problem.
    Without going into technical details, the process includes the following steps:
    At the end of the process a Patch CERT is needed in order to switch the checking phase off!

    Repair IMEI:

    1. IMEI repair
    2. Patch cert

    Cert write:

    1. Write cert
    2. Patch cert

    If you get the following error message:
    "There is an active patchcert on your phone. Please remove it.", it means that the steps are not in the right order or the phone is not in factory settings.
    In this case, you need to use the software again and start the process over. You can also try to click on Patch cert again and this would initiate a factory reset.
    We currently support 3000 modem versions but naturally, there might be versions we did not add and this can also cause problem in the above detailed process. We add new versions every day, check the available versions daily but there are still modems that is not supported by our solution. In case you meet such case, please do not hesitate to contact our support. If you need prompt solution, you can try to re-software the phone to an other version with Chimera.
    It is important that you do this phase with the Chimera because we allow the re-software for version that we support so the success is guaranteed.

    Hi there.
    Unfortunately, this operation is not compatible with your phone's security patch level. Also you could try and do the following process. After the patch, turn off the phone, insert it into the phone's SIM card, turn on the phone, and live 60-70 seconds. Then check the IMEI status normally you will see NG, but after this time the IMEI status changes to OK and the phone has a normal network.
