Hi,
First, thanks for the great tutorial.
I tried rewritting IMEIs on my UMI eMax but as you mention ...

Sorry but you cannot do that. The easiest and most risk-free method is to format the whole flash chip (except the boot loader) with SP Flash Tool, then flash the stock ROM and after that, use the SN Writer Tool.

Thans for the answer.
I really need to. Because UMI registered the eMax as a non 4g compatible phone in the international imei database, i am not able to fully use my phone in my country. The phone operators restricting it based on its imei.
Apparently UMI doesn't care about incorrectly registering its phones in the imei database, as the problem has been brought up multiple times but without any outcome.

So by using the format tab in SP flash tools then flashing the phone with the download tab and then using sn writer i should be able to write a new imei, correct ?
Will this reset the protection on nvram ? and do i need to backup some files like nvram or wifi_custom ?

I've heard about such issues only from users of the French Free network. Everybody else can connect to 4G networks (if the compatible LTE bands are available) without any issues.
Formatting your phone will erase the nvram partition, so it won't be existed anymore but the SN Write Tool can recreate it.
I highly recommend you to backup your nvram partition before formatting your phone.

I'm having a problem with the UMI MAX phone. I tried several times to insert a ROM STOCK. The SP Flash Tool works fine, the process completes successfully, but when the android settings begin to appear, system errors start to appear and the device restarts several times until it hangs on the UMI startup screen. Can I recover my device?
Thanks if you can help me.

Try to power on your phone without SIM card and SD card installed in it. If that doesn't change anything, try to flash your phone using another computer and another USB cable. If you still face the same issue, as a very rare occasion, your phone might have a defective flash chip inside. That cannot be repaired, the only way is to replace your phone.

You can find your IMEI numbers on the packing box of your phone.
