Firmware error

The essence of the PMT problem

Each smartphone or tablet uses a partition table (memory layout), with which normal operation of the operating system is carried out.

When flashing the device, special software is used that uses its own phone markup data. If this data (usually in the Scatter file) differs from the actual phone markup (PMT), then the error PMT described for me changes for the ROM it must be downloaded, and the user, trying to reflash his device, gets the problem described above.

Another reason for the occurrence of such a dysfunction is the corrupted partition table of the phone itself.

Problem identification

I’ll make a reservation right away that you will perform all the actions I offer at your own peril and risk, since undertaking the firmware of your device without having special technical knowledge is a great chance to turn your phone into a lifeless “brick”.

First, check the status of the phone and whether your software matches this unit with IMEI. If the software you use does not match the version of your phone, then look on the network for the exact version of the firmware that you need.

If the phone does not start at all, or after turning on it hangs on the logo, and trying to reflash it using the SP Flash Tool, you get the described error PMT changed for the ROM it must be downloaded. then, probably, the phone has significant problems with the partition table ( it is damaged).

It also happens that the versions of some files included in the firmware used do not correspond to the declared ones, and this can also cause the dysfunction described by me.

Fix the problem

How to fix PMT error changed for the ROM it must be downloaded

Method 1 In addition to the above search in the software network, corresponding to the version of your phone, you can select the “Firmware upgrade“Instead of”Download Only»During firmware. The firmware will download the special bootloader, but at the same time, if it differs from the telephone bootloader, the device may “die”. In most cases, this method allows you to fix the specified problem, and the phone will work without problems.

Method 2 Another option for solving the PMT changed for the ROM problem is to select the firmware, and then format the phone using the Flash Tool SP (select the Auto Format Flash option), then download the firmware (download flash) without selecting a bootloader. After completing the firmware process, you will need to fix IMEI.

Method 3 Turn off your phone and run the utility for flashing JV Flash Tool firmware. Select the “Format” submenu and click on the “Start” button. Connect the turned-off smartphone to the computer and wait until the formatting process is complete. After receiving the “Format OK” label, turn off the device. Now go to the “Download” subsection, select the scatter file and click on “Download”. Reconnect the device, and the firmware process itself will begin.

How the error correction occurs according to method 3, you can see the:

Method 4 Open JV Flash Tool, select the scatter file. Click on the “Format” submenu, select the “formal all except bootloader” option. Then format the device and try flashing it again. In some cases, this option has proven effective.

Conclusion

In most cases, the cause of the described error “PMT changed for the ROM it must be downloaded” is a mismatch between the actual markup of the phone and the markup used in the scatter file. The methods I have listed are designed to correct the problem, be careful, and if you are not a professional in this field, then entrust this matter to a specialist.
