I want to flash my htc evo shift to a different network is it possible?

You can't flash a CDMA phone(HTC EVO 4G LTE on Sprint(CDMA network) to a GSM network(Straight talk which is on T-Mobile's network(GSM network) the hardware is not interchangeable. A GSM SIM card is not the same as a 4G LTE SIM card(UUID) they store different data. GSM SIM hold your carrier account information that authorizes you to use the network while a UUID only hold data that is relevant to you accessing the 4G LTE part of the network the remainder of your carrier data is stored on the phone hardware.

You can not flash a phone to a service provider unless they accept foreign ESN's. Virgin Mobile does not allow foreign ESN's The only provider i'm aware of that allows foreign ESN's is CricKet.

Through the Google Play Store is the only way I know of. If it isn't working go into settings > Apps > play store, clear out cache and force stop the play store. Then try updating flash again.

Have you attempted taking the battery out and while the battery is out holding down the power button for a few seconds? If this doesn't work,
First test your charger to ensure proper charging. Clean charging ports. Remove battery and clean brass contacts with alcohol and q-tip

Hi,
Either you have to flash the mobile or get a unlock code you have to take it to the service center, because to flash and get unlock code (both) the mobile has to be connected to the computer with a cable.

hope this helps,thanks!
