[GUIDE] Sprint sim unlock & Flash

[spottarget]

sucks

Mine doesn't pick up bars until I go into the mobile data settings, select "available GSM networks" at the bottom, then search for my network and select it. It should pick up bars after you do that.

we need like a gsm patch or something to fix the whole manual thing about going to network settings and select the network manually.

I'm in Europe (have been for several months) and nothing is working for me... I had called sprint before hand and they pushed a bunch of crap to my phone and failed to unlock it. I do the trick mentioned here and it still says sim lock enabled and pretends there is no sim inserted.

I hope they will cancel my contract for me when I get back. I am really annoyed that I bought this phone to bring here and can't friggen use it.

EDIT: I got it working by first putting it into AIRPLANE MODE.. then after I do the process and reboot, i was able to take it off airplane mode and switch the sprint sim for my movistar SIM

Thanks everyone who helped. Sprint was useless.

I've read that some have had issues with the tray not aligning the card correctly after it shut. Could that be your issue?

use the stock rom for the unlock. wont work on aosp.

Hello Mate.. thats for the awesome work on this..

I just got a sprint one and tried this method to unlock but this same error 3 popped up. I am on stock rom itself and just unlocked bootloader and rooted the phone.
Can u tell me what could be wrong in my case ?

Also is there a way to directly go to that menu thru root explorer ? If yes, whats the path.. I will bypass the TE commands.

Hi, I'm also having the error 3 issue.
My phone: sprint HTC One

trickdroid ROM based on android 4.1.2​

root, unlocked, s-off, h-boot 1.44, teamwin touch recovery​

adb, fastboot, htc drivers (except htc sync) installed​

i've tried running the commands from the phone using terminal emulator and from my computer through adb
when i type "am start com.redbend.vdmc/com.htc.omadm.test.TestMainActivity" (after giving SU access), i get the following error:

[email protected]:/ # am start com.redbend.vdmc/com.htc.omadm.test.TestMainActivity

I think you have to flash a stock sprint ROM ...
Trickdroid used a gsm based ROM ported over to sprint. It may not contain the right stuff to make this work.

There are some users reporting this failing with the same error despite runinng a stock ROM.
Also, would it have to be a RUU recovery to regain full stock or could I just flash the stock ROM?
Other thoughts: is it possible to reach that OMADM menu by putting a code into the dialer? I've looked around online and no codes I've found get you there so I wouldn't know how to find the OMADM one, if there is one.
Last question, if i revert back to stock and do the sim unlock, will it stay unlocked if I flash a custom rom, like S-off and root stays.

Ohhh... ****... Silly me

I can't even read things correctly.. instead of vdmc, I wrote vmdc.. whoever are getting error 3 with stock rom check carefully u are typing it ABSOLUTELY RIGHT and not doing something SILLY like me..

Its wroking guys !!! Thanks a lot :good:

Thanks,

So what's the consensus on this working with US carriers? From what I'm seeing international, overseas users of this method are using it perfectly while users in the US can't get their ATT/TMobile sims to work...

Anyone in the US got this working?

I've heard that it will work with AT&T and T-Mobile

I have T-mobile. I was able to do sim unlock but I have to register T-mobile network manually every time I lost connection to the cell tower (which happens alot in my house) Kind of suck. I would like to install T-mobile Rom on Sprint HTC one but there is a no go for now
