[Q]Getting LTE back.

Alright, so I've tried everything, everything I can, to get the LTE back working on the HTC one. And i mean everything, I've updated the Firmware to the current firmware, flashed, and reflashed the ARHD Rom that I use, clean, and dirty installs, over and over again, and i just can't seem to get it to recognize that we are in LTE, it insists on using H.
I've gone into the dialer code, and checked it displays HSPAP, and when i switched it to LTE Only, it refused to find a signal at all. I don't know what i need to do, the oddest thing was, i hadn't made any changes! It was working on LTE before i gave it to my girlfriend, when i did, I did the 4.2 fix, to clear up the internal memory by wiping it, then ADP pushing ARHD to the phone. Low and behold week or two later i notice that it's saying H, when i know we are in LTE coverage, because well its where we live, and it had been before, and because my phone right next to it, has 5 bars of LTE glory.
Any tips, suggestions, anything, would be GREATLY appreciated, cause I'm stumped. I've never played with radios, aside from updating the firmware with whatever those come with, and as i said, it was working fine before doing the memory fix to clear it for my girlfriend to take over. Please please, someone have a suggestion, i want her phone to run the LTE it should when she's not one wifi.

Reflash official ruu back?

check the APN.

Can't find the official RUU, and the APN settings seem to be fine, alongside what everything says it should be.

S-OFF ?
What's your CID?
The loss of LTE is certainly interesting, It shouldn't be firmware or rom dependent. Can't be a frequency issue since this phone was working on the carrier's network prior. Have you tried putting your sim card in the phone ? Her sim card in your phone? There is always the chance of carrier error.

I'll have to look when I get home, I have it set to super cid right now. As for the sims, I had briefly, but not for an extended test, it displayed the same h for my Sim.

If it's super CID then that also likely means your S-OFF.
You can flash any RUU, but might want to start with one from your carrier if available.
lots of stock roms/ruu here:

So I just clicked the more info tab on your profile. I saw vancouver and thought Canada but your profile shows USA and ATT. you're using the apn "phone" ?
For ATT here's what you want:

What's the difference between flashing RUU and flashing firmware? Plus I've seen very small mention of my CID being responsible possibly, that going back to S-on improves speed. I don't personally believe it cause I had s-off with my Sim working fine.

S-On improve speed? That's completely illogical.
The CID has nothing to do with network connectivity; it's just there for identifying which RUU or OTA should be applied to your phone. Essentially version control for the various carrier models.
An RUU will wipe all data from the phone and rewrite all the firmware, recovery, and system. You can absolutely try extracting the firmware.zip from the RUU I linked and flashing that by itself in RUU mode via fastboot.
FWIW, I'm using an ATT branded One that's S-OFF and super CID on ATT Gophone. I've never had an issue with LTE connectivity. I also have three friends/relatives with s-off/super CID ATT branded One's using Net 10 [ATT] and they also have never had any LTE issues. All the devices I speak of are running full GPE conversions but I don't believe that to be relevant.

Alright, I just did a firmware update last night, to the current 3.62 whatever, official HTC one firmware, but I'll give it a try. Can I restore data from a nandroid backup, without it returning my firmware, or do I just need to long reinstall everything?

Nandroid doesn't backup firmware. It grabs /system /data /cache, boot and recovery.
you can RUU and then test LTE, when you get LTE working flash your favorite recovery and then restore your nandroid. LTE should continue working.

Thanks, I just tested hers with my Sim, went into *#*#4635#*#* and forced LTE and it worked! So now I'm trying to do the same with her Sim and if the problem continues we will be making a stop at ATT today.

[Q] super cid,flashing other carrier roms

can someone plz clear few things up for me..i know this,if i have super cid and i do..i can upgrade my firmware with non harmon version or the h.k version..but when it comes to flashing roms from the att or the tmobile or international threads im bit confused...as long as i have cid set tpo super cid can i jus proceed flashing the rom like i normally would in the sprint section ??or do i need to change the cid to att cid number before flashing there roms?or do i jus leave thecid set to super cid?i have yet to try another carrier's rom cause im still uncertain on exactly how to do so..i dont understand why we need roms ported over to the sprint section if all we need to do is change cid to super cid and flash away..surely im missing something ...i have super cid now and the htc m8 sprint h.k phone sprint phone....can i just go to any carriers development threads and choosewhat ever rom i want?..man i hope so cause that opens the door to soo much..i relize this is a newbie question and if not posted in the correct secrtion on xda id prolly be banned for good..lol..but i am in correct section so plz be easy on me

Well you could flash other roms but unless their files have been set up for sprints network you won't be able to do much there are still other differences as well between each rom for each carrier

Same question, except I don't need my phone to work on Sprint. I'm using my device Internationally. Could there be any issues?

Well you'd also have to make sure the partitions are set up correctly as well as you could end up with boot loops or worse ie: android revolution 22.1 will boot directly into bootloader unless you use a correct sprint kernel that allows for it to boot. If anything try using bad boyz rom and apply their sim unlock method. (provided your using a sprint phone internationally)

[Q] Error while searching for networks

Hello XDA,
Before I came to this subforum I was under the impression I had a regular HTC One, I got the same error message and then figured out I had a Sprint HTC One.
Now I had the issue where I had no service at all, my Sim card seemed to be detected but I ofcourse had the wrong firmware on it likely causing the issue.
So I got new firmware and a cm 12 (also tried stock rom) rom, but comming up to the same error message. The Sim card is detected and I am asked to fill in the pin for it which I was not when I had the wrong rom/firmware. I am not sure what is going wrong and I hope you guys can help me.
I am in The Netherlands and I am using radio Baseband - 1.01.20.0515
Thanks
Edit:
Tried:
RUU's:
I tried flashing this ruu, no success.
I flashed 3.04.651.2 RUU and 5.05.651.2 RUU after that to be sure to have a radio (according to this thread) but with no success. I also tried flashing the radio Baseband - 1.01.20.0515 again after it dit not work.
Radio's:
Baseband - 1.01.20.0515

bump

I wish I could help. My only suggestion is to try to run the Sprint RUU to reset the phone back to stock with the latest firmware to see if that helps. Unless I'm mistaken, the issue is that Europe uses GSM and Sprint is a CDMA carrier. So, you may not even have the right radios in the phone. The only saving grace is that it is a worldphone that uses LTE bands so you might be able to access those. But, you may have to unlock the SIM card first. At this point, I'm pretty much just throwing out ideas I've seen on the site since I've never been in the situation myself.

The hardware is capable of doing it. Before I started flashing it worked fine. I've tried going back to the stock rom but with no success.

sounds like you flashed a gsm rom on a cdma phone, and now the partitions are messed up, only way out of that that I know of is running the RUU for the sprint phone.

I've tried that no success

Sprint HTC ONE M8 - HK Edition - Suddenly No Sim Card

Dear All,
I am on Sprint HTC One M8 (831C), was install with 5.02 - RUU H/K exe, S-OFF, using the GSM Carrier Vodafone- India.
Four days back was roaming out from my state, while in flight I kept it in air plane mode, the phone felt down and the problem emerged.
NO sim Card, also the phone's camera has is not working. I unlocked the the bootloader, installed twrp and swiped the Bad boyz Sprint ONE M8 Lollipop HK v3.2, assuming that I may resolve the issue but no Luck.
I have tried the sieempi.eu tick, also from settings but it says that your phone will switch to CDMA mode.
Request experts, to suggest the workable solution please...
Regards
Karan

Make full twrp/cwm backup. Clean flash any custom 4.4 kitkat rom, and do simunlock using this method. Restore full backup. If it still doesn't work then you probably broke the simcard/reader when you dropped it.

Dial *#*#4636#*#*
and select GSM/UMTS

here the solution

htc One m8 Sprint invalid sim error

i am using a htc One m8 that i recently updated to android 6.0 marshmallow and everything seems to be working fine till i woke up this morning and realised the phone was off. turned it on and realised the phone said invalid sim.
in upadting the phone I used the RUU and initially the phone said invalid sim , then i went through the process by writing the OEM CID to 11111111 and the network started working. Tried that this time and its not working , any suggestions?
The phone runs with 6.20.651.3 marshmallow.
Thinking of running the RUU and going through the process again but dont wanna lose my stuff.
Update: i set the CID to 11111111 through fastboot but i boot the phone and went to dailer and dailed *#*#4636#*#*, went into phone info but the CID there was bb89557. any ideas why it different.

Hi
Had the same issue. Running the RUU wont help even. As of now, am trying downgrading to 4.20.651.1 and then updating the radio thru terminal emulator. Will update if it works.

Well an Update:
i managed to downgrade the phone to 5.0.1 firmware (lollipop) and found a thread on Sim Unlock and used it to make the network work. Finally the networks working fine and i get mobile data connection but its GSM, dont think that can be changed so am keeping it like that.

I just switched to Project Fi (I love my Pixel XL) and wanted to use my HTC One M8 as a data only device. The only issue is I am having problems getting the GSM Sim to work. would you mind posting what method you were able to get it working?
Thanks

I faced the a similar problem when i tried to convert mine to GPe, the phone never booted so i decided to put sense back, but my sim was not detected after that,i was looking around for a few hours i finally fixed the problem, i made a flasheable zip mixed with firmware 3.28.401.9 with the Sprint Radio and bingo its working aagain, i flashed it with RUU method, and my phone is S-OFF
