T-Mobile Data dropps every 5 minutes - One (M8) Q&A, Help & Troubleshooting

Hello!
I have an unlocked HTC M8 and I'm using it with T-Mobile. During almost a year I never had any issues with it but since January I having a recurrent issue: I can only have data for a few minutes. To solve it, I need to continuously disconnect and connect data.
During this time, I tried some "solutions" I found online:
_Install different ROM
_Add new APN
_Go to #*#*INFO*#*# and change to US band
The phone is still S-ON so I didn't change the radio (actually there is something that bothers me: the phone should be from T-Mobile but the model number is M8_UL_CA that, accordingly with the internet, it's from ATT...)
I noticed this after I returned from vacations in Portugal where I used a local SIM card...
Does anyone suffer(ed) from the same problem? I'm getting so frustrated...
Thanks

Hello, no one had experienced this before?

I'm on t-mobile with no issues.

To start with I would do the 'adb reboot bootloader' then do the 'fastboot getvar all' and post it (removing the imei and serialno). Mine is below as a reference. Also a little history - my is an actual t-mobile branded phone, I was rooted with lollipop and unrooted and had t-mobile upgrade my phone to MM. Once done I dev-unlocked and then did a backup and have installed custom ROMS. Currently I am using ACIP by coachcrey and I don't have any issues.

I bought the phone on Swappa from a seller that said it was bought from HTC directly. After I start having the issue, I rooted and installed a couple of different ROMs until I decided to go back to stock
Thanks for any help you might give me

The product ID m8_ul_ca can be AT&T or Developer's Edition.
The main version indicated with digits "1540" agrees with Developer's Edition. So it may be true it was purchased from HTC directly.
We have seen a lot of AT&t variants "converted" to be unbranded (Euro, Dev Ed, etc.). But since the ATT version has the ATT logo on the back of the phone, they would have to have replaced the back plate to remove all the branding. The model number on the back of the phone (fine print near the bottom) may also give a clue to its origins (although if it was replaced, it may not even agree with the product name in getvar - which is the most reliable info).

How exactly did you return to stock? Your own nandroid, stock nandroid from XDA thread, or RUU? If not your own nandroid, what version number?
Although, the fact your data issues coincided with using a foreign SIM; I'm inclined to believe that was the cause, rather than anything to do with custom ROMs, restoring stock ROMs, or the fact its the Dev Edition.

Sorry, I can't remember how... I followed a guide and I think I downloaded HTC official ROM.
As for the foreign SIM, how could that affect the phone? maybe it damaged the SIM tray? How can I solve it?

Thinking about buying used M8, bricked

Hey guys!
I'm thinking of buying an used One M8 (AT&T). I'm from Croatia, where we also use GSM so I can try sim-unlock it.
However, the guy says that phone won't boot up ("only boots up one picture").
It only boots up into Fastboot. With: radio, openDSP saying something like invalid_ver_info. Not sure what that is.
Is it a soft brick or a hard brick? I'm thinking it can be changed just by installing stock rom.
What else should I check out before buying it?
(it's very cheap, and I'm not budget-friendly)

Htc one m8 needing to go back to stock rom

Hello, i recently bought an M8 from eBay and it came with Version 4.4.4 but wouldnt update to anything else (your phone is up to date) so i unlocked the boot loader and using Sunshine S-Off i did the S-Off thing as it was set to On ...then i downloaded and installed the Revolution HD custom ROM which all went ahead smoothly but all i want really is the latest Stock ROM for my phone and wipe the Rev HD and instal the original ROM and firmware but i really dont know where to look for the Firmware & ROM ...i know how to flash them but have no idea what to look for when searching for them.. could anyone help please?
I will try to give as much info as possible (i'm quite sure the CID was 1111111 or something like that before the HD flash)

I hope that's enough info..when i spoke to HTC they said, going by the IMEI that the phone had a US carrier or desighed for US and was on T-Mobile? The phone works fine in the UK so i don't understand that unless the seller on eBay has altered it?
Thanks a lot for your time and help
I have downloaded RUU_M8_UL_M60_SENSE70_MR_BrightstarUS_WWE_6.12.1540.4 and firmware-6.12.1540.4 ...are these right anyone? i'm really not sure..i have been reading about this all day and it still baffles me

Desperate: HTC Reboot Hell, even recovery

First of all thanks for anyone who can help me.
I'm quite desperate after spending countless hours on XDA trying to get my phone to work.
I received the phone (international HTC one M8) in a somewhat broken state and I am trying to fix it.
Originally the phone had a 4.4 rom on it which caused the phone to reboot constantly, I couldn't get the rom to update either so I decided to flash it to Marshmallow.
Set S-off, I flashed TWRP and installed the latest Skydragon rom. Wifi wasn't working though so I flashed ruu firmware 6.12.401.4b. The rom worked, Wifi worked, but only downside, it only booted while being charged with a cable, and the sudden reboots started occurring again. So I think the battery might be shotty too. Anyway, I got a device tree warning too, so I reflashed a different Ruu, reboots started occurring even when trying to get to recovery. So I went back to the 6x ruu, tried to flash Skydragon again and then I spiraled into real trouble. Each time I tried to flash a rom, the phone reboots while installing. I even tried the MeID changer to make sure it fits with the firmware.
Long story short, the reboots got worse, I can't get into recovery without rebooting. If I run recovery over fastboot, I get into the recovery, but it reboots when I try to flash anything. I also tried Phil's revovery but same problem.
I can get into fastboot, hboot and bootloader just fine though.
Any help is greatly appreciated.
Need more info to proceed. Please do a fastboot getvar all, and post the results (delete IMEI and serial number before posting).
Sure Thing! Thanks!

It is indeed an M8_UL which is the GSM/Int version.
However version-mics shows: XF SHIP S-OFF
M8_UL_XF is something I have heard of before on a forum (few pages back, there's a thread with a similar case).
Anyway, an ordinary M8_UL will show 'PVT SHIP S-OFF'.
XF is either a 'different' variant or some type of engineer/prototype device.
What do you think @redpoint73?

Here is the getvar all from my M8.
Notice the version-misc.
Thanks @murtaza02, I finally got the damn thing to work because of your comment I realized my CID was bogus and wasn't corresponding with the MID, so I fixed that using fastboot, flashed the EU 6x FUU and the corresponding RUU (https://www.androidfilehost.com/?fid=24369303960687057). And behold, It booted into Marshmellow!!
Now though, the phone still keeps shutting down (not even rebooting) and won't start android without being plugged in. Could this be software related at all? Getvar says the battery is good and when it craps out, (most often when trying to enable WIFI) it shows the battery charging just fine. I still see the device tree warning on boot btw.

As I said, yours is XF and a normal M8 is PVT.
Your device will accept a MM firmware, however there may be a SLIGHT difference in partition/partition sizes hence the device tree error and irregular behavior.
Your CID was not bogus, it was just SuperCID which is used to bypass the CID check during an RUU/FUU flash.
I'm still trying to figure out why (and how) yours is different.

I don't know much about the XF variant, either. But I recall @ckpv5 pointing out the difference to an XF user a week or 2 ago. So maybe @ckpv5 can jump in and give some advice here?
@redpoint73, Thanks but I fear @ckpv5 might not have any more info to go on. I found his post where he referred to the XF variant. He said it's quite possible a US variant, definitely has different partitioning than the PVT version, but didn't know more. I've also seen posts of people suggesting it's a Canadian version.
I bought it on Aliexpress if that is any lead. But in all honestly, I'm really starting to worry I have an expensive paperweight.
One more potential clue, the Alie page suggests the phone only has WCDMA, no LTE, could that be a lead? Ow and one more clue, the model number on the back of the phone is: OP6B100x

BRAND NEW HTC One M8 Issues

Hey All,
I've bought a new HTC One M8 from Dubai and traveled to Egypt and had the following issues:
When i tried to make a phone call, i can not hear anything (the other side hear me) when i go on speaker mode i hear the other side but they can not hear me.
I tried to use the headset to make calls (tried several ones but they were not working), however the auxiliary jack is working in my car.
The phone overheats.
I thought it was a software issue so i tried to update the software but it keeps telling me that my software is up to date (i guess 4.4.2 or something like that). I googled and tried to update manually through RUU but could not find any one that is compatible with y device until i came across one that update the system but turned to be AT&T update (RUU_M8_UL_M60_SENSE70_ATT_MR_Cingular_US_6.20.502.5_combined).
I need to know if this is really a hardware or software issue, the device is brand new and can not imagine that it had all those faulty issues, also returning the device to Dubai and activating warranty would not be easy for me.
Here is mobile information and hopefully someone can help me.

AT&T version will only receive updates when located in the US and connected to the AT&T network.
This is something you should have researched before buying.
Although, as the phone has been modified/hacked to be s-off and SuperCID, you can also convert to Developer's Editions, or even change model ID (MID) and convert to another M8 version.

That RUU should work.
If you RUU successfully, and still have the issues, you are probably looking at a hardware issue.

Need Some Assistance With HTC ONE M8

Hey guys,
Was wondering if I can get some guidance on what to do. My HTC One M8 is originally an AT&T device, I am currently in the UK but my Vodafone sim does not connect to any network. I've been trying to get it to work and I think the problem may lie with the firmware? All I would like to do is get connected on the Vodafone UK network with 4G/H+ speeds. Will it be possible?

I see that your version-main is wiped, so maybe the problem is from rom, you can download your stock ruu from here: http://www.htc.com/us/support/rom-downloads.html
Note: All of your data will be deleted, so backup first.

The blank version-main/OS is caused by TWRP 2.7.x. It was a bug in that version that caused it. To get it back, flashing the RUU will work. Also, updating TWRP then (re)flashing firmware will have it show again

Is the device supposed to be SIM unlocked? If not, AT&T version is SIM locked by default, and another (any other but AT&T) carrier's SIM will not work.
