Hello XDA Users,
I currently need some serious help, as I seem to have made a mistake with flashing a radio to my device.
I have a Verizon branded HTC M8, currently unlocked and using it with T-Mobile.
Today, I flashed a AT&T radio since I read that it helps with data dropping because it utilizes more bands.
Once I flashed the new radio, my phone will not detect my sim card.
I can't even select a network operator, nor enter any APN settings.
I did not make a NAndroid Backup of my device, so I can't resort to a back up.
I tried flashing several other radios, but not my luck none have worked.
My current device setup is as follows..
Device - Verizon HTC One M8 / Unlocked (T-Mobile)
Rom - ViperOneM8 6.1.0
Kernel - ElementalX
CID - 11111111 / S-OFF
Can someone please explain to me what went wrong, or how I can get my Sim card to reactivate.
I've tried two different sim cards, and a few online tricks none have which worked. (Tape / Trimming SIM)
This can be closed, I have solved my problem.
Updating to the latest firmware can be a lifesaver

Hi, I'm a noob, forgive me. I bought my Desire HD from Singapore, which came unlocked. Then, I downgraded it, and rooted it. Everything went fine. Then one day, after flashing a rom and flashing the recommended radio (forgot which rom), my phone suddenly lost signal, and I have been unable to get it back since. It says "Limited Service Emergency Calls Only" It detects the SIM card, but when I try to connect to my home network, it says that my SIM does not allow a connection to that network. So, I flashed back to stock, both Froyo and Gingerbread, assuming that it replaces the radio with the default radio. (Is that so?) However, that does not work. Now I fear that I might have flashed the wrong stock rom, which might be the problem. Does anyone know what is the stock rom for the Desire HD shipped to Singapore unlocked (software number, etc) and how can I get it? Also, how can I check the rom's information (software number, whether it is for asia, or is it WWE... etc) THANKS A LOT
PS. I tried getting a replacement SIM. it does not work. it is a 128k sim card. (Does that help?)

Also, other SIMs work on my Desire HD. My SIM doesnt, but works on other phones.
Dear All
first of all, sorry for my bad language.
my problem started when i purchased an used Inc2 from swappa, i am expert in flashing ROMs for HTC phones.
when i got the phone, i s-off, installed recovery and installed custom ROM supports GSM, as i am living outside USA, and everything was good (GSM and data)
one day, suddenly the phone was not able to get a H data, only E, so i decided to factory reset to solve the problem, i return to stock ROM using RUU, then when i turn it on for the first time i discovered that its still connected to verizon Network and gave me a roaming signal, i know nothing about verizon network or how to disconnect my phone from their service.
don't tell me to contact the original owner, because i purchased this phone more than one year ago and i totally forgot from whom i toke it.
THE MAIN PROBLEM NOW, every time i insert my local SIM, the phone switch from roaming mode (CMDA) to global mode (GSM), which is OK, but when i receive or make a call, it restarts automatically !!!!
i had tried all the ROM, RUU, radios in the development section, with no hope, so, i think the problem is occur from the conflict between CMDA signal an GSM signal!!!???!! or something else, so i guess the first thing i have to do is disconnect the verizon service, BUT HOW?? somebody please help me
any thoughts folks?
Can you post your phone's settings, mainly the ones under "About Phone" including kernel, mobile network type, service state & software information, etc.?
With a local Sim card, it is possible that you device would boot up & switch to Global Mode (by default) with preference for CDMA, but you should be able to manually change it & semi-lock it to GSM only? What happens when you tried that?
There is a # of GSM only Rom that you can flash, assuming you've rooted it again & maintained S-Off with a custom recovery re-installed - and, that it was properly Sim unlocked.
Im on GSM with chilly's beanstalk 1.30 (4.2.2) and I have no problems, check if a wipe with antivenomSDW, helps.

I recently flashed the latest version of the Candy5 ROM. Everything is working well, except it thinks I have no SIM card. I was thinking this might be a radio/baseband issue, and could be solved by flashing a new one. Am I correct? If so, how can I do this? When I try to find the radio firmware, I can only find it for the GSM HTC One. Thank you. I am S-OFF by the way.
make sure cellular network settings is set to RUIM/SIM and not NV
I have a Verizon HTC One M8 which must work on an international GSM/LTE network.
I bought it on ebay and it was working before I tampered with it. It was giving notifications about non-Verizon sim, so I tried to fix that by flashing a custom ROM.
However, now there is no signal at all)).
Please give me a hint or a piece of lazy advice.
Settings > Mobile data > Preferred Network
If what above is said ,does not work,(you select gsm network and it revert back to CDMA immediately then it maybe a firmware/ROM problem,that sometimes happens with me,try flashing lollipop firmware again,and a lollipop/mm ROM that never failed you in the past.in my case vanir aosp often give me those problems, flashing turbo ROM solves it.)
Agree with the above that no signal after flashing a ROM on the Verizon version, is often due to outdated firmware.
Also, make sure the ROM supports the Verizon version, as many don't (and can also cause issues).
The Verizon version is SIM-unlocked from the factory, so I would think the notifications of the non_VZN SIM could just be dismissed? Or did they actually prevent the function of the phone (with the non_VZN SIM)?
Nah ,I think he meant everything was working before he tempered with it,so you were right,he could have dismissed it.but curiosity can be trouble maker and solver both.hehe
Hi all. I have purchased a second hand 10 locked to Telstra and have tried everything humanly possible to get it to accept a Vodafone sim. It is currently running the 1.95.841.3 firmware (Telstra stock) and is driving me bat **** crazy.
I have even given in and paid Telstra $25 to unlock it. The only drama is when inserting the Vodafone sim upon rebooting it doesn't offer up the option to enter the sim unlock code.
I have sporadic connectivity with no data connection, and trouble registering on the Vodafone network.
I have unlocked the bootloader, it's s-off and I have successfully changed it to wwe and unlocked us variants, tried the latest viper and eventually resolved to flashing back to stock rom.
Every thing I have tried still has the same issue. Mobile data is disconnected because service is unavailable.
Do I have to flash a different radio, firmware or just give in and switch to Telstra?
Any help would be greatly appreciated
