I'm from Venezuela, I have an HTC M7 bought one used internationally released version, here in Venezuela there are three operators, movilnet, digitel and movistar, the phone uses 3g in the 3 operators. A few days ago I start to unlock the bootloader and change the recovery installing ClockworkMod, up here all right, install as I say forums and tutorials, restarting the phone all the same, but when looking for networks I listed 3 operators. Movistar 2G and 3G, 2G and 3G movilnet, DIGITEL 2G and 3G does not appear the digitel ..... got lost, Will unlocking bootloader made ​​me lose 3g? and no apn settings or the network just stopped recognizing the cel 3g digitel which is 900 mhz .... I appreciate your help and solution

NOTE: I commented that I install original RUU of m7 u_l and the phone stay as factory, but the 3g on the 900 mhz it is not taking that could have happened to the equipment, if the grab 3g 3 operators?

Fist dial *#*#4636#*#* to open the test menu of your phone. Select ''phone info'' tab and make sure preferred networkd type is set to ''GMS/WCDMA/LTE auto''. Then check if your apn match your operator information. You can delete and create a new apn if needed.

Hi everyone, i'm the OP of the post.
So why are you using 2 different accounts on xda?

14. Create only ONE User Account

You are allowed ONE User Account at XDA-Developers. If you create additional accounts, Moderators will disable them and your original account may also be disabled or infracted.

If you are really the OP of this thread, this mean you were using 2 different accounts at the same time for at least 3 months

Yes, I know, but that account is an account of a friend who did me the favor of posting the problem when I could not. The account is not mine, the case of the problem, yes.

ok I understand

so you said you lost 3g after unlocking the bootloader and flashing a custom rom? Have you tried to restore the phone back to stock?

can you post the output of "fastboot getvar all" minus your IMEI and SERIALNO please

After unlocking the bootloader only, after that I realized I had lost the 900 Mhz band, then I changed the ROM to see if it solved, and nothing, I changed Radios, and nothing, I used several Ruu's, and nothing. I'm stuck on this.

I tried to lock the bootloader again, and it said "Relocked", that not solve my problem, so that i'm looking to set this on "Locked", to see if a miracle occurs.

unlocking the bootloader will not disable radio bands are you sure you were getting 3g from that carrier before you have unlocked the bootloader? Are you sure your carrier frequencies are compatible with the M7?

see above post (edited) waiting for you getvar

900/1800 Mhz should be supported, I dont know why but your issue is not related to an unlocked bootloader I'm 100% sure.

What is your apn?

My Apn are ok, is the same as it was before the problem.

So if the issue is not the bootloader, What caused the problem? Any hardware failure?

There any method you can recommend me to take?

If you don't want to share what is your apn, I can't help you more.

Maybe, I don't think so.

Go to your carrier and check with them that your device is set correctly to work on their network. You should also try different radio versions.

good luck
