Dangers Of Messing With Your Phone

Hello, everyone, I'd like to share my experience, get any help if someone can, and warn some future people.
So a few months ago i rooted and ROM swapped my HTC one. It was great, I loved it, it was fast and simple.
I tried to change the ROM on it the other day and everything went down hill form there. Basically I ended up having no service and everything else seeming to work fine. So after spending an entire day trying to fix it with BD619, i had to call my carrier today. Now i have the sprint phones, and the sprint service, but i have Credo as a carrier. God knows why. They essentially gave me nothing saying my phone must be bricked and they can't help me.
One thing they did try however was to have me put in a ##xxxxx# number, and there i saw and could edit my MDN and MSID, instead of showing my my phone number and the MSID number they both had "No" written. So he had me edit it and put it in, but when i click "commit changes" it said "commit failed" so if anyone knows anything about that or could help me there, it'd greatly appreciated.
Lesson is, even if you think you know what you are doing, and are careful, weird stuff can happen, and if you have an Odd carrier version of an already less support model of phone (the sprint version), then be EXTRA careful.

Have you tried simply running the latest RUU and reverting it back to stock?

Yes, twice

This is not an uncommon problem but it happens with certain HTC ones and not others. I have helped a few other people with this issue. Most likely, your current ROM is set to RUIN/SIM in Settings-> More-> Mobile Network -> Subscription settings. It needs to be set to NV. If you can't get to this setting, you need to flash a ROM that has the setting available. CM 10 based ROMs all seem to have it. If your phone does not automatically reactivate, you can flash to a stock ROM and use the handsfree activation function and that should get you back up.

Okay so i just flashed a CM 11 build. and Holy S*** I have ******* service! I cant make calls, it says it's not authorized. And i don't see the option you were talking about, in mobile network, i see , Data Enables, Data Roaming, Preferred Network type, System select, (then grayed out) Access Point Names and Network operators, (then not grayed out) carrier settings. When i click carrier settings it says "Unfortunately, the process com.android.phone has stopped. and it takes me back a screen.

Try flashing a CM10 ROM. I've always seen the option there. The kitkat ROMs I have used do not have the option except for the Nocs GE.

The only way something like this happens is one of two things.....
1. Ur a noob
2. Your a dev and your testing ril on your rom
The only way to fix this which is a cleared meid of some sort......flashing cm10.1 is the only way and aquiring service by switching to nv....once there everything is fixed just flash/restore back to your rom.

i'd kinda like to argue a point here as this just happened to me. i am certainly not new to flashing, starting back with the mogul and having almost every sprint smart phone since then unlocked (windows) or rooted (webos and android).
Using TWRP and previously running ecliptic 4.3 i wiped caches, system and data then installed the 4.4.2 from team d3rp and voila... no service no meid no nothing.... yes i have the latest radio on my phone.
i guess my point in this is that there's a number 3 that you didn't mention.
3. sh!t happens and it's not n00b related.
for anyone else that has this issue... flashing CM 10.1 worked for me. i didn't even have to set up anything, it just picked up signal. so i rebooted, wiped and nandroided back to 4.3 and all is well.

Did you flash a rom that was meant for another carrier?

I didn't... it was SuperOneK. i'm certainly not blaming the rom though. especially not when others are flashing it fine. the ONLY thing i can think of possibly happening is a bad download. I was in a rush and didn't check the md5.

I had a similar problem when flashing miui. Nothing worked. Even went back to a sense backup and nothing worked.
Commit failed as well.
Here's what I did to make it work again.
Flashed cm10. Change the network settings for CDMA. (Boom it SAID I had service..but didn't).
Rebooted a few times (probably not necessary).
Flashed a sense 4.3 ROM that was close to stock.
Update msl and all that. Commit.
For me..changed LTE/CDMA to just CDMA (no 4g in wv).
Boom it worked again. Hope this helps!

Unlocked Sprint HTC One on AT&T

I see this question asked a few times within other treads but wasn't ever really answered clearly in my situation. I have successfully network unlocked my Sprint HTC One. When I put the sim in I get no errors and dialing 4636 brings me to the menu where I can change to wcmda preferred..gsm only... etc.. The phone reads the phone number off the sim and lists it on this page as well. Heres my issue I have verified that phone will cover the same bands where I am so that should not be an issue. I can not get a signal with this phone with 2 different sims. I made sure I did all the obvious things with the settings, the APN's, flashed different radios, and tried different options is the 4636 menu. Ive used different roms as well...When I go to select or search for my network both options are grayed out.... I can connect to Verizon and I can connect to sprint towers but no Dice on ATT. I am currently on version 4.1.2 and have tried all available radios. Has anyone had success in the new York New Jersrey PA area with using this phone on ATT. If so what is the setup you are using.

The Sprint HTC one has blocked the carrier id's for domestic use aka att. You can however if your s-off you can flash the initial release radio the first radio when the Sprint HTC was released and it will allow you to connect to domestic carriers.
I'm in Ohio so not too far from you and I can pick up T-Mobile and att using the initial release radio, it is the only radio I could get to pick up signal.
Here is the first radio released http://d-h.st/HHD

Im currently s-off and flashed that radios. When I select network connection the two options are still grayed out. Could the rom choice make any difference ?

Same here....help please

I am having the same issue with my Sprint HTC One. I've tried everything mentioned above and no one has answered. Are you guys still having this issue? And if not what did you do to fix it. I have a Sprint HTC One with S-Off, Unlocked Bootloader, the Radio that is listed here and the latest ViperOne 5.7.0 ROM. Thanks!
EDIT: My phone is unlocked and I have been using T-Mobile for the past month just fine, and want to try AT&T.

I have figured out a way to make AT&T work with the phone. When you place a Sprint or Verizon sim into the phone, it will immediately unlock the network search options that are normally greyed out. I click automatic select and immediately remove the sim and replace it with my AT&T one. Even though the phone complains that the sim was removed, I can click ok, then quickly push the automatic select again before it greys out. I then wait a minute or so until it fails to find a network. I then quickly click the network search option. The notable thing at this point is the only network that shows up is MARITIME. if I click on that, it registers me to AT&T. I have tested the phone and it works great. But it seems to bump me off the network at some point. I dont know if its poor reception or the ROM itself doing it. And if I restart the phone, I lose it as well. So I have to repeat the steps again to get back on AT&T. But the thing to know here is that the phone will work with domestic carriers with no problem. Its a matter of locking to AT&T and staying there. Surely one of the brilliant brains on these forums can figure out how to keep it working. I basically stumbled onto this by playing around with it.

Good job finding that. When it kicks you off of AT&T's network it did that to me when I had T-Mobile as well, so it's not just AT&T. Glad you were able to get AT&T to work on your phone tho, kudos.

Problem Registering with Network after flashing GPE ROM

Hi There,
I have been scratching my head for weeks now with no luck after searching hundreds of times for a solution and I hope I can find it here today. I purchased an Sprint HTC One M8 from Best Buy together with an unlock code. I received the phone in Africa and I was excited to try it out. However, when I put in my local carrier Sim Card I could not receive an unlock code request. I tried many fixes but I did not get anywhere.
After days of trying one fix after another, I decided to unlock the bootloader successfully, install a custom recovery (TWRP), I was also able to achieve S-OFF using sunshine's tool and write CID to 1111111. After that I tried different kinds of unlock methods like using config.dat and using the Sim Unlock Helper tool. But no luck.
I went ahead and flashed my device with the Sprint M8 GPE 5.0.1 ROM. I was successful and I noticed under settings - cellular networks I am able to see all network operators in my region. However, when I try registering with my carrier I get a "Sim Card can not connect to this network" message. I do not know why.
When I dial *#*#4636#*#* and access phone information, I selected GSM only in preferred network type. Under select network band there are only 4 options: Automatic, USA Band, Band mode 6 and Band mode 7. I selected Automatic.
I have literally tried everything I can think of as I am kind of new to this. I really hope someone can point me into the right direction in unlocking my device once and for all. I love the phone and I do not wish to sell it off. Please let me know if there is any more information that I can share. Thanks for your time!!

Hello,
Are you still having this problem?? Cause if you do I am really curious if you found a fix for it? I am experiencing the same problems. A friend of mine gave me this One M8 which has no owner anymore so i decided to fix it. I replaced the screen due to water damage and did bootloader and root succesful. I can also see my network providers but as soon as I try to register it also says "Sim card cannot connect to this network". Who has the ultimate fixxx???
Greetings,
Rob

H/K M8 Radio/network type/MEID problems

Hey guys!
I have the one M8 Sprint H/K edition with S-OFF which seems to be unlocked by now (I tried unlocking methods found here) because it accepts other carriers SIM (international) cards and shows up Sim menu, but I can't get it switch to WCDMA mode and it says "Radio Off". But that's one thing. The other weird thing is that when I recieved the phone (bought on eBay) in "about the phone" -> "account" it had the following info: [email protected] which belongs to Verizon instead of Sprint! I thought it is unlocked and contacted Sprint International, they checked IMEI and serial number and said it's not blacklisted but not unlocked!
So then I reset account settings (in "activate this phone" menu) and now it shows "imei number@hcm.sprintpcs.com".
But I also had the other problem even before the reset. In "about the phone" I could see IMEI # but MEID had and still has 00000000 (eight zeroes), even though fastboot getvar all command shows the correct MEID!
In *#*#4636#*#* menu IMEI is shown as 00000000 (eight zeroes), RADIO OFF and can't switch network type, even though the phone shows correct phone number if you hit "update" at the bottom of this very menu.
Have you had anything like that with your phones guys?
Maybe there's a way to force the phone to switch to WCDMA mode?
Now it's running lollipop, but nothing changed since 4.4.4
Hope we will find the solution together

Looks like the phone had lot of work around by previous user. If you can confirm that gsm working and you can call using gsm simcard I can help you with wcdma activation. By the way, HTC never released a Harman kardon edition for Verizon, and it must be Sprint (color black with champagne gold accent). Also, need not worry about MEID as anyone can easily change if the phone is s-off. Hope the phone didn't have a bad esn

Thanks for reply!
The phone is pure HK edition. Before sending it to me friend of mine (in the US) confirmed that phone works and activates on Sprint network. I even contacted Sprint to ask them if the phone is unlocked, and they said they had no request to unlock this particular phone and it is not blacklisted (clean ESN).
In about a week I recieved the phone in my country, checked bootloader and it was "Locked" (not "re-locked") and "S-on" running 4.4.4. Then I unlocked bootloader with HTCDev instructions and followed "unlocking" instructions found here. The phone picks up foreign SIM card because "Sim toolkit" app pops up as soon as I insert SIM card. But GSM option is still greyed out and I'm unable to select different network types. If I try switching to UMTS/GSM from settings - mobile data menu it simply says "no SIM in the phone, swithcing back to CDMA mode" and if from *#*#4636#*#* menu it doesn't let me select other network type. Also the radio is still off fore some reason... If needed I can take a brief video showing all settings I have.
I was surprised to see Verison account on Sprint phone, but telling you as is.
P.s. friend of mine owns unlocked H/K M8 and I compare his settings to mine, he has radio ON and GSM is not greyed out and he can switch network types back and forth.
Thanks for help!

That means the phone is not SIM unlocked. Check the different threads on how SIM unlock under Sprint forum. Once it is SIM unlocked you will receive the gsm signal and you should be able to make calls. If your friend had contacted Sprint (if he was the owner of the phone) for SIM unlock they could have done it in a minute (they do for international travel). Well, anyways there are different methods to SIM unlock and make WCDMA work on your phone. Before that if you want to try changing the network type, use this app - https://play.google.com/store/apps/details?id=de.mangelow.network works very well.
Also, I am not sure for gsm if you even need MEID. If you want to restore the original MEID, try this link - http://androidforums.com/threads/guide-how-to-restore-service-if-youve-lost-your-meid.352598/
Good Luck!

Hey!
FINALLY!!! I got the phone unlocked!
I decided to write original MEID/ESN to the phone with CDMA Tools app and right after reboot the phone said "switching to international mode" and hooked up to my carrier's network. I suspect I got it unlocked a long time ago, but couldn't complete the unlock due to zeroed out MEID/ESN.
I'm sharing this info with all people here who got stuck with the "unlock" - before throwing your phone away check if it displays MEID normally. If not, then check original MEID/IMEI/Serial number in bootloader - barcode and write it down. Then write it to the phone with CDMA tools.
If someone needs an advice, just ask.

Hey man, thanks for posting your solution! i'm glad i don't have to throw my phone away after all...
I would really appreciate if you could explain more of how to use the CDMA tools to write the original MEID/ESN to the phone. I'm from Mexico so if it's posible that you can use a low level english or provide a link to a guide or tutorial, it would be extra awesome ! Thanks again

I'm having a tough timw getting the meid in place, looks it just keeps reverting to old. Are you using DFS or CDMA ?

M8 root wont allow for carrier switch

I bought my M8 from a guy a year ago and it wouldn't receive any data(only worked on wifi), so i took it to Sprint and the guy said it was because the phone was rooted (i see a prompt for #SuperSU and the guy i got it from was recently returning home from asia somewhere where he used the phone) he couldn't touch it. found another sprint who took it overnight and wahlah, it was fixed, but he didnt tell me what he did to fix it because the phone is still rooted, or atleast still has the prompts telling me the SU bianary needs to be upgraded
i broke the phones charging port a while back, and switch to iphone and now am switching back to m8 now that i fixed it but im on tmobile now, and cant take it back to sprint to have the guy refix it.
i put the working tmobile SiM into the port and the phone still says Sprint as my service provider but also has the error message 'invalid sim card 4G services are unavailable' but wont let me click on the error. i took it to tmobile and they couldn't do anything with it because the 'access point names' field is greyed out and wont let you click on it
Does anyone know what sprint may have done to get around that or what is causing the SIM not to be recognized. The guy i got it from originally had it on TMobile, til i switched it back to sprint, so it is an unlocked phone, it just has something deeper going on w the point names i guess?

Post ur getvar all.. s-off or s-on. If phone is still rooted then try the SHORTCUT MASTER and search for apn settings and edit it ... the apn settings are greyd out as the phone is locked to sprint (showing invalid sim) post hboot screenshot .
