I just bought a US Sprint Version M8 and It is driving me Crazy.
I still am not able to unlock it. HELP HELP
My device is htvdev boot loader unlocked.
Rooted as well
I first tried the Universal sim unlock method via where you flash in the config.dat file via simlock option, everything failed except it said successfully applied imei code.
I popped in a foreign gsm sim card, still it was locked. Nothing happened
I than proceeded with the SuperCid 11111111 trick, I was able to change the code successfully.
But when I tried in ma foreign sim card. Nothing worked.
I after doing the above two steps I than tried the HTCOMADM_SPCS.apk mod trick on my currently installed stock rom.
I renamed the original HTCOMADM_SPCS.apk and HTCOMADM_SPCS.odex to something else
And pasted modified HTCOMADM_SPCS.apk and changed permission to rw-r-r.
I ran sim unlocker helper program, granted it SU rights reached the page with the start button but when I press the start button no pop up window appears. Nothing happens at all.
I than decided to flash my Stock Rom to BSC_Stock_Rooted_M8_RLS_21 Rom
I tried the same trick and switched the original HTCOMADM_SPCS.apk with the modified file.
I open sim unlocker helper, grand su access and it takes me to start button but when I press start nothing happens still.
Now with the new Rom when I pop in the sim card I get Invalid Card. Please contact customer care.
Note: I also changed the network to gsm only directly via the menu and also by using the #*#*4636*#*# code
Attached is a screen shot :
Can someone tell me what am I doing wrong?

hello i have the same problem but i dont understand the steps, can you tell me where did you get the steps? thanx

To get unlocked helper start key works you should rename all HTCOMADM files in the app folder plus all HTC OMADM PLUGINS ,
SO they are 4 files to rename not only 2 . And renaming should be changing name and extension . If you renamed only those 2 files mention in the op thread the start bottun won't work ,
Being on stock Rom is recommended plus installing the firmware mention on the above thread. It's 100% works on Sprint
I am using viperone Rom and it works excellent
Amigo, podrías decir me cómo hayar esos archivos. Yo los he buscado con el root xplorer y nada. Lo otro. Mi m8 es de sprint y le instale la custom rom de sprint pero la versión de harman kardom.. Estará bien o tengo que poner la original?
Lo tengo con S-off, super cid 11111111, bootloader y la versión de Android 4.4.2.
. Por favor te pido me ayudes pues me tiene desesperado el tema.

Default Bootloader and undo simlock process

Guys, if all requirements (s-off, non-sprint, external sd) are met, does it matter if the bootloader is locked or unlocked for this?
Is there a proper way to undo the "simlock" in case something goes wrong during the flashing, or the phone will not connect to the networkt anymore?

I have an HTC One M8 with a 3 Austria branding.
gsm, sim unlock, unlock
