The ultimate HTC hardware combined with Google’s amazing Nexus experience and so you get the HTC One Google Play Edition. The hardware config stays the very same as offered by the regular sensed HTC One, Quad-core 1.7 GHz Krait 300 CPU, Qualcomm Snapdragon 600 SoC and a full HD 4.7” display making its way to the realm of today’s Android devices.

In this articles we will explain how to repair, change or update firmware in HTC Desire 650 in a few simple steps. The whole process will be performed without any specialist tool by using just a computer and a microSD card.
Let’s start with a few things that we need know before downloading firmware needed for your phone.

  • CID = carrier ID, CID is like a firmware security code. For example: If your phone CID is HTC__034, then you need a firmware with the same CID as your phone.
  • Main-Ver = bootloader, if you have to flash your phone, and your phone main-ver is 2, then you need to flash your mobile with rom which main-ver is 2 or higher, you can't write rom which main-ver is 1 or lower than one on your mobile.
    (this depends on the security level of your phone S-ON or S-OFF when S-OFF you can downgrade firmware if S-ON you can't).
  • Phone Model ID - is the name that your phone got in firmware, you need to know this name to select the correct one.

Downloading Necessary Firmware

  1. Firstly need read info from your HTC phone. Can do this follow tutorial from here:
    How read info from HTC phone by usb cable
  2. Once we have all info, we search firmware by model ID and CID.
    Example:
    (bootloader) product: a56_uhl
    (bootloader) version-main: 1.00.401.4
    (bootloader) cidnum: HTC__034
    (bootloader) security: on
    Bootloader security level
    As you can see, we need a firmware for A56_UHL phone model with a minimum version of v1.00.401.4.
    The phone has S-ON which means we can't downgrade firmware on it and the cid number is HTC__034.
  3. To find the correct firmware, we must know the country to do this search by cid number for that check table on our page HTC country code.
    In this table, you need to find your phone cid number. When we have it. In the first column, we can see which firmware is dedicated to this given cid.
    Here HTC Europe means firmware without any brand for the area of Europe.
  4. Now it’s time to search this firmware in order to download it. First, try our upload section. If you can’t find the firmware for your phone then, try other links that we provided above. To find the correct firmware, we need to find our phone product code. Example for A56_UHL it's very important to find firmware with exactly this model name. Every HTC firmware has the Product name and Country Customisation in this part of file name.
  5. When you find correct firmware, you need to select the correct one for our cid. As I mentioned before, we need to know the operator name get it from our table. For example, we need HTC Europe firmware that means we searching for the firmware that got word Europe in the file name.
  6. After finding the product name and customisation, the last thing is checking if the firmware version that we have on our phone if is the same or higher because we have got S-ON so your phone can't be downgraded. In our example we need firmware v1.00.401.4 or higher.
  7. This is firmware for our phone. Just download it and we can start flashing the phone.
