Italy to Australia

Hi, i have a note 3 sm-n9005, I bought this in Italy and I use it with a sim Italian, if I go on a trip to Australia, what should I do? I mean, the frequencies are the same?
how can I see if my device has the "region lock"?
I would not go there and have the smartphone locked.

The N9005 has all bands necessary. It will work.
If you are on CyanogenMod the region lock should be disabled.
Just in case, you can check the thread [APP][2013.11.04] RegionLock Away v1.3 [ROOT].

any "note 3" has the region lock?

sm-n9005 is a note 3 international model, it should be unlocked.
If you want to check for the "region lock", install Phone INFO ★Samsung★ app or Shortcut Master app, open the Menu --> 'Secret Codes Explorer', scroll down to the secret code 7465625 (SIMLOCK) and tap to launch this code. (Note: root is required)

Yes and no. The N9005 does, depending on the region of purchase. UAE seems to be clear, but EU is 100% Region Locked. Most Custom ROMS get rid of it, and if you're rooted, try the above mentioned Region Lock away.

If it's bought in the EU, it has the region lock for the EU. Regardless of the fact that the N9005 is the international version. On stock, anyway.
SIMlock is NOT THE SAME AS REGION LOCK.

SIMLOCK is just a name for easy-to-remember the secret code 7465625
In fact it includes 4 types of lock: Network, Network Subset, SP and CP lock.

If the phone has region lock, you can see it right on the box, even before opening it. Please see the attached images.

Just because they're under the same menu doesnt mean they're the same thing.
Simlock locks the device to a specific provider. It is also illegal in the EU since 2011.
Region lock locks the device to a region, but you can use any provider in that region.
One has nothing to do with the other.

I assumed that the region lock is one of the above 4 types of lock: Network lock, Network Subset lock, SP lock and CP lock.
Isn't it?

Those are different kinds of SIM locks. The Network Lock is the main SIMlock, the network subset lock specifies the specific network it's on. This enables when one provider uses the network of another. The SP and CP one nobody is really clear on. (Not even the lads at Samsung and T-Mobile.)
They all lock the device to a specific provider by blacklisting all the others in a file.
The Region Lock is a list of whitelisted providers by provider ID. Its principle is the same, on that you're entirely right.
Sadly, unlocking the SIMlock doesn't unlock the region. (If it did we could charge them with breaking EU law and get rid of the whole thing.)
More info is to be found in Chainfire's thread on the subject. http://forum.xda-developers.com/showthread.php?t=2470551
And now I really wish swiftkey would stop autocorrecting to Sherlock every time I type SIMlock. . It's getting a bit silly. That's what you get for lending your phone to a colleague for 5 minutes. :silly: -.-

By the way, SP lock is Service Provider lock. Don't know about CP lock.

Haha, I get that a lot .
Well, a Service Provider is the same as a Provider, so it's probably all for the different types of SIMlocks different providers use. (like the US method is difderent from the Asian ones.)
Basically each phone has a series text file that goes [providercode] = 0 for locked, and = 1 for enabled. (It's not as crudely written as that, but I was never very good at coding My robot was supposed to run an obstacle course, but instead tried to eat the professor's foot for an hour.)
There's the file that lists all blocked providers (big list), which is the SIMlock (stop it Swiftkey).
And there's another file somewhere else that lists which providers are unlocked. That's the Region Lock.
There's another one of these lists that determines which providers have LTE enabled. But unlike the regionlock, that one varies per CSC. (As does the SIMlock.)
Most important fact is that Chainfire found a way to get rid of it (All one has to do is Root it).

That's the one. Ironically, people haven't been able to find it on the LTE version of the NotePro 12.2". Any idea why that could be? Because I'm out of ideas on that and I've not rooted it so I can't check.

[GUIDE] UNLOCK ADITIONAL BANDS FOR QUALCOMM DEVICES <OnePlus One EDITION>

STOP!
By following this guide, you acknowledge that you and you alone are responsible for the proper-functioning state of your device.
I am not responsible for any harm that may come to your device.
Click to expand...
Click to collapse
In an attempt to make this guide short and comprehensive and also to prevent the completely uninitiated from doing something stupid, I'm going to skip babysteps like <power on your coputer> or <browse to x folder and doubleclick on y>
I start this assuming anyone following it has a basic understanding of what they're doing, what ADB is and also of the risks that come with messing with their device.
Introduction:
This guide will show you how to alter the default baseband frequencies of your qualcomm-based device, augmenting them so that (theoretically) it should work more like a global phone.
Those with an international version of the OPO can still follow this guide, if only to check your unlocked bands against those of your fellow chinese OPO owners. I'm of the opinion that even the international version lacks a few GSM/WCDMA bands, so no harm in trying to unlock some aditional ones.
This guide will, however, NOT UNLOCK ADITIONAL LTE BANDS. At least not for now. It will be updated if and when someone discovers a way to tamper with the LTE bands.
The Guide:
1. Download this archive containing all the necessary files and extract it wherever you please.
2. Enable Android Debugging on your phone and connect it to your computer, making sure MTP and PTP are not enabled in Storage > USB computer connection
3. Open up ADB and type the following:
Code:
adb shell
Code:
su
Code:
setprop sys.usb.config diag,adb
4. Launch Device Manager and look for the Other Devices expandable menu.
5. Right click on the first device listed under that menu (the first of the two A0001 devices listed there) and choose Update Driver Software, Browse my computer for driver software, Let me pick from a list of device drivers on my computer, Show All Drivers, Have Disk and Browse
6. Browse to where you extracted OPO SPECIFIC QUALCOMM BAND UNLOCKER and locate the OPO Diagnostics Driver folder; Inside you will find 32bit and 64bit versions, pick the one relevant to you and inside you will find an .inf file that you will Open. Accept any warning messages that might pop up and let the installation of the driver complete.
7. Once everything is done installing, under Modems in Device Manager you will find HTC USB Modem. Rightclick and select Properties; In the Modem tab in the top left corner you will see Port: COM<number>. Remember that COM<number> or write it down or simply leave the window open for future reference.
8. Open the OPO SPECIFIC QUALCOMM BAND UNLOCKER folder, locate and install QPST 2.7.411 inside QPST > QPST v2.7 Build 4.11
9. Open QPST Configuration, go to the Ports tab, Add New Port (right bottom corner); In the Port field type in the COM<number> you wrote down/remembered from step 7 and in Port Label type OPO and finally click OK (left bottom corner). If you've followed all the steps correctly until here, you should be able to see this in the Active Phones tab:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
10. Locate and launch RF_NV_Manager.exe in the bin folder of the QPST installation directory (normally C:\Program Files (x86)\Qualcomm\QPST\bin)
11. Once you have RF_NV_Manager.exe open, click on Setting > Comport and select COM<number> from the dropdown menu and click OK; Go to File (top right corner) and select Read from Phone and let it finish.
12. Scroll down and click on line 1877 (NV_RF_BC_CONFIG_I); Copy the number displayed on the right-hand side field (the one next to < unsigned 8 bytes > Band Class(s) Supported >)
13. Locate and open mzTool_1.2.1a.exe inside OPO SPECIFIC QUALCOMM BAND UNLOCKER; select Decimal under Input Radix (top left side); Paste the number you copied in step 12 into the Decimal field under RF BC Config. You should now see your currently available bands in the Bit Information field underneath. It should look similar to this:
14. Go to Band Performance (NV Value) tab and check all the GSM and WCDMA bands; Copy the number in the Decimal field under RF BC Config (2,307,813,334,319,039,360); Copy it into a text editor and remove the ","
15. Go back to RF NV Manager and paste the clean number (2307813334319039360) into the number field next to < unsigned 8 bytes > Band Class(s) > --- if you paste the number with commas or brackets instead of just the number, you're an idiot.
16. Press WRITE NV then go to File and select Write Changed NV Items To Phone; Wait 23 seconds (because I like arbitrary waiting times), disable Android Debugging on your phone, unplug it and reboot your device; Once it comes back on, it might take a few seconds for it to acquire signal so don't panic.

NEW LTE UNLOCKING GUIDE
Courtesy of @Albirew
Conclusion:
The only real way to know if the whole thing got applied is to do steps 1 through 13 again (obviously skipping installations) or if you are in an area where you previously had bad or no reception.
I've tested this on my 64GB Chinese OPO running stock rooted CM11S. Everything seems to work properly radio-wise, no worse than before. I'll have to travel a bit around to see if i get better or worse reception.
I'll edit this thread with any relevant information if any becomes available in the future or if anyone feels something is missing.
Thanks:
Thanks to @BlackSoulxxx for his original work with the Qualcomm baseband software and for the modified OPO Drivers
Thanks to @olokos for his original tutorial
Thanks to @Glatzi for bringing the original thread to my attention
Thanks to @fards for finding the diagnostics command that made all this possible
Thanks to @Albirew for writing an extensive LTE tutorial

Thank you for your help I was stucked because MTP in debugging mode was checked, and also I because I did not get the right command (setprop sys.usb.config diag,adb instead of setprop persist.usb.eng 1 in the terminal.
Cheers
PS : Love your comment "if you paste the number with commas or brackets instead of just the number, you're an idiot." ^^

Great!!! well done @devilsshadow Thanks a lot.. :angel::angel::good::good:
And @-Nx- Thanks once again for linking me to this awesome thread!!!!

As Galaxy S5 can use the European LTE 800mhz band, could we check the bits from S5 and try to use them in our OPO to enable 800mhz LTE band?

So for now you don't know how to unlock some LTE bands for the OPO?

The S5 is an Exynos powered device, cant really do much for our Qualcomm based handsets. Besides, as far as I know, no OPO version has the 800MHz band availabe. Check out the band chart below with the available OPO bands:

Not as of right now, no. I'd need confirmation from someone with a chinese OPO in the US to test if flashing the latest CM11 does anything to unlock the additional LTE bands that the Chinese OPO lacks. Otherwise, like I said in the OP, this tutorial is only for unlocking aditional GSM/WCDMA bands.
I'm sure someone smarter than me will find a way to get to the LTE bands as well. Just give it time.

OK thx! I really appreciate your work! Btw the EU GS5 has the Snapdragon 801

Got manically busy week ahead, so not sure I can get to my pc to look at the lte.
If you can do some screen shots of the codes in nv manager (like the 1187) there might be something that shows up.

I'm not 100% sure but I think think so. Flashing a new rom also flashes whatever radios come with the rom so that might overwrite everything. Need someone to test this.

As this is still a work in progress, any further studies into the matter (from different devices owners as well) will only help us further our goal of unlocking full LTE.

Could you list what base band available after the hack? That will be very helpful if you could post a screen capture for the step 13 after the modification.
I am particular interested on 1700MHz (AWS or WCDMA-4) at 3G. Thanks a lot

European version has the Snapdragon 801. In Korea they announced a LTE-A version which has the 805 processor. They also said that they will not sell the LTE-A version outside if the Korea.
Since we have the same SoC as the Galaxy S5 European version and S5 can do the 800mhz LTE, technically OPO should be able to use that band alao.
Because radio chip is inside of the Snapdragon 801 SoC, I don't believe that there is any hardware limitations.

About FDD-LTE and WCDMA restriction in China.
It may not be related to Baseband.
What I found is that Color OS could modify modemst1 or modemst2 partition to unlock the restriction in China. It has nothing to do with NON-HLOS.bin.
But here's another possibility that we could modify NON-HLOS.bin directly to get FDD-LTE and WCDMA in China supported. But it is not what color os crack does.

Guys, QC has different modem for different kinds of chip. Yes the radio chip is inside SoC, but it need MDM9xxx modem chip

Just exclude the baseband when flashing with flashtool and you'll have your bands. OTA update is a different story.

Yes. So it seems the phone does support volte but has to be enabled.. Much like the us996 model.

The biggest problem is how lg has implemented volte at least on the dual SIM model of the Indian version. If u place sim1 which has volte and sim2 has 3g then change data to sim2 it will not only disable LTE data of sim1 but also knock off volte making sim1 completely unusable. Can any of you try this and confirm? I had a s7 before and it would let volte be active and only disable LTE data of sim1.

Hi, just a side question for you.
Does your H990DS with TWN software support 3G Video Calls? Eg. Dial phone number and video call, not using third party apps like Skype, Facebook messenger or WhatsApp.

Thanks for your reply. Appreciated.

So is there an option to flash the singapore version and enable volte ?

Hi sir
So how to flash Singapore firmware kdz even if i have Taiwan version in H990ds
Please let us know

My phone switches to 3g when making a call too, bloody annoying.
There are a lot of versions out there, does anyone know which is best and can firmwares be changed? https://lg-firmwares.com/lg-h990ds-firmwares/
My current SW version is V10c-TWN-XX build NRD90M which I'd guess is Taiwan (no VoLTE) if I flashed the singapore firmware (H990ds10d_00_OPEN_SG_DS_OP_1227.kdz) would I get VoLTE?

This thread seems really dead now for some reaason.
Well here goes, have LGup installed and am downloading singapore firmware H990ds10e_00_OPEN_SG_DS_OP_0314.kdz. Will let you know what happens.

H990DS new regional rom success and now have VoLTE
I installed LGup and flashed it with the phillipines rom. My phone still says V10e-TWN-XX in the SW info but I have VoLTE support now, weird or what.
Anyone else wishing to give this a go will need to install Lg Bridge from the LG website which comes with the required USB drivers, then install LGup (LGUP_Store_Frame_Ver_1_14_3.msi) found here https://www.mylgphones.com/download-lg-up-software. You will also need a DLL (LGUP_Common.dll) for the H990DS https://drive.google.com/open?id=0B0-_MIhGeuKhNWFpcUNfc2FKeG8, copy this to C:\Program Files (x86)\LG Electronics\LGUP\model\common\ after installing LGup. if the folder does not exist, create it. replace the existing file with the one in the link. the one that comes with LGup will not work.
The regional versions of the firmware for the H990DS can be found here https://lg-firmwares.com/lg-h990ds-firmwares/
I chose to upgrade in LGup, it retained all of my settings and I lost no data.
I'll test it out tomorrow and see what the VoLTE calls are like.

thanks for sharing btw SEA rom has VoLTE support as well, in case you needed it in future. I installed it earlier today and everything seems to work fine.

What SW version was your H990DS shipped with? if you have changed it, does it show up in sw info?

I installed LGup and flashed it with the phillipines rom. My phone still says V10e-TWN-XX in the SW info but I have VoLTE support now, weird or what.
Anyone else wishing to give this a go will need to install Lg Bridge from the LG website which comes with the required USB drivers, then install LGup (LGUP_Store_Frame_Ver_1_14_3.msi) found here https://www.mylgphones.com/download-lg-up-software. You will also need a DLL (LGUP_Common.dll) for the H990DS https://drive.google.com/open?id=0B0-_MIhGeuKhNWFpcUNfc2FKeG8, copy this to C:\Program Files (x86)\LG Electronics\LGUP\model\common\ after installing LGup. if the folder does not exist, create it. replace the existing file with the one in the link. the one that comes with LGup will not work.
The regional versions of the firmware for the H990DS can be found here https://lg-firmwares.com/lg-h990ds-firmwares/
I chose to upgrade in LGup, it retained all of my settings and I lost no data.
I'll test it out tomorrow and see what the VoLTE calls are like.

I was on the TWN rom originally.
I flashed the SEA rom and now have the VoLTE icon but I cannot turn it on. I have spoken to my mobile carrier and they have told me VoLTE is enabled on my service so the phone seems to be the problem.
I just rebooted my phone and the VoLTE icon is gone haha...

NUF26K is for Verizon and contains a different baseband with fixes specific to Verizon. N4F26O is for all others- including Bangladesh... besides OP has already flashed a different radio.

Your thread is very confusing. Are you saying your phone is from NA (H1511) carrier locked (SIM locked to carrier). Please verify and confirm your phone is NOT carrier locked. Secondly, where exactly are you trying to use the phone and have you tried a local SIM from that location.

This was a reply on nexus help forum

Dear v12xke,
Your qouted thread was actually a reply from my same post on nexus help forum. If possible pls visit this post on nexus help forum: https://groups.google.com/a/[email protected].
I post some screenshot there.
I don't think my phone is carrier locked. I am from Bangladesh and i tried various sim from various carrier from Bangladesh. Those Sim worked fine when i purchase my Nexus 6P from local store. This issue happened when I enrolled to Android N (beta program).
Sorry for my English. Thanks

Have you fixed the problem?? i am from Bangladesh also.

I am also facing the same issue. My phone was bought from google play store and delivered in Texas. It was unlocked and no carrier dependent. I used the t mobile while I was in Houston and when I came back to Bangladesh I have been using the local SIM without any problem until last week. I have tried almost everything (flashing the stock image, flashing a custom rom: purenexus, restoring efs backup and now trying to flash latest radio image). I don't think any of them going to solve the issue if the phone is locked for the country.

What were you doing when this happened to your phone last week? There is no "country" lock. Your US phone was sold "carrier unlocked" and is supported in Bangladesh via GMS 900 and 1800, and UTMS B1/B8. All of which are supported by the H1511 (NA) variant. That is why it was working before. If you were lucky enough to have a TWRP backup of your own EFS partitions, restoring those should have worked BUT there was a time when the EFS backups from TWRP were not working because of an error in the script which was corrected in later versions. There is a thread and sticky dedicated to this issue. If not, format them completely and reboot the phone. Have you tried a SIM from another carrier there, preferably one that uses a different frequency as your carrier? Grameenphone appears to support the most frequencies of all the carriers in your area. What happens when you put your TMo SIM in?

1. I was enrolled in android beta and installed Nougat 7.1.2 . I practically did nothing that could hamper the phone functioning. Yes it was working fine in Bangladesh, and in other country as well.
2. I was not lucky enough to have a TWRP backup of the EFS but I got a back up EFS and restore following instruction. It didn't help. I am using TWRP angler 3.1.0. angler. I also flashed the radio to latest one (3.82) and with no success. You can have a look at the phone information and the drop down menu (Screenshots).
3. I have flashed the stock Nougat 7.0 and reboot the phone several times. It didn't work. Can you explain a bit about "formatting and rebooting". Need to know whether I did the right thing.
4. I have tried another SIM from another carrier but still it didn't work. These sims are working fine in my Nexus 5 which I also bought from Houston.
5. Haven't tried the Grameenphone sim but I don't think it is a SIM issue. and I don't have the TMo sim with me now. It is now being used by my mother who is currently in Houston.

>>3. What I meant was to manually format the EFS partitions using fastboot and note any errors:
fastboot format modemst1
fastboot format modemst2
>>6. The thread on TWRP/EFS botched backup/restore does not really apply to your case. It forensically details how the dev mistakenly coded the EFS backup script, why it broke many phones, and how it was fixed. Your problem is more likely one or both of the EFS partitions is corrupted. Your best bet is probably finding someone else with a fully working N6P, make a backup of their EFS partitions and then restore that backup to your phone. A pretty tall order.

I did that couple of hours ago already. Downloaded the working EFS partition from a reliable source and flashed through fastboot. Didn't solve the problem. I will check again with the command you have mentioned to see which partition is corrupted. What do you suggest me to do if there is an error in any of the partition?

bro, same problem.Here, does tinkering with EFS will work?? Has anyone really solved this issue? I am finding a pattern here, in Marsmallow, there was no problem. But as soon as we switched to Android Nougat, this "no service" issue arised. But, who knew updating a OS will brick a phone!!!! I wish i could go back in time and continued with Marshmallow. I have spent 47k on this phone. Now, i wish nobody buys phone of google or huwaei . DON'T BUY NEXUS 6P

from where did you download "working Efs partition"? can u provide me the link. I am helpless here

Google will not admit this but there were major security flaws in factory images before jan,2017.
They patched it in Jan. But effected users like us(who got effected on 2016) got proper fu***.
Hence, the only solution is:
find a nexus 6p user who has everything working....make a backup of their EFS using TWRF (ROOT their phone)...and apply that efs to your phone. Both the phone must have same build version. Both phones must be unlocked to use TWRP to make backup amd restore EFS. N.B. EFS are responsible for detecting celluar modem in your device. Maybe it got corrupted.
if anyone is gracious enough to upload their stable NEXUS 6p Efs backup with build number mentioned, it would be really helpful to us, the affected users.

Firstly this only solution didn't work for me. I restored the efs partition collected from a reliable source (link provided in the conversation between me and Mr. Dhananjay) matching the build number but it rebooted with the restored EFS but the problem is still there. I have also flashed latest radio image (3.81) and it didn't work as well. If you have time you can read the conversation I am having with Mr. Dhananjay who is well aware of the issue and supplied me the fresh EFS. You can try the same solution which he offered, who knows it might work for you. If it fixes your device let me know. Best of Luck.

[Guide] Cricket - Get Marshmallow! (6.0.1) - HTC 626s

Unfortunately, Cricket has apparently decided that our phone isn't worth an update. However, with a little knowledge, you can get it up and working in no time.
Thanks to @nightbreed813 for the original debloated MM ROM. Thanks also to @noaone for his tips. Without them, I'd still be on Lollipop.

}
Prerequisites:
You MUST have a custom recovery (preferably TWRP) installed. No ifs, ands or buts. If you don't currently meet this requirement, see this guide: https://forum.xda-developers.com/desire-626/help/complete-detailed-step-step-root-t3217505
Easy method:
Download the modified zip from this post
Copy it to your device's internal storage
BACKUP YOUR CURRENT DATA. This should work, but you don't want to be caught off-guard. DO IT!
Remove the SIM card. Keep it removed until you have completed the setup process. Replacing it before then will screw Android up, and you'll have to reflash.
Wipe System, Data, DALVIK & Cache
Flash the file you downloaded from this post.
Reboot your phone and wait for it to start the setup process.
Bypassed hands-free activation. Tap 'Done' in Self Service and accept that there wasn't a network to register to.
You can reinsert your SD Card at this point. Cricket will now set the network up for you.
.
You should be done now. Enjoy Marshmallow.
Manual method (Long):
Download a zip from nightbreed813's post.
Open the zip (preferably with Windows File Explorer), and, without extracting, navigate to \META-INF\com\google\android\
Open updater-script with a text editor, preferably Notepad++
Change the first 2 lines to
HTML:
#ASSERT
unmount("/system");
, replacing what's there.
Save, and let Windows recompile the zip
This zip should now flash on your phone. Follow the Easy Method instructions (excluding step 1) to install.

Hi, thank you for providing the instuctions. I flashed the rom to my 626. Unfortunately I'm not able to connect to LTE on GSM band. I guess this is because it is a Sprint Rom that's designed for CDMA network technology ?

I see no reason why it shouldn't; Cricket is on AT&T's network. Still, make a TWRP backup just in case it doesn't work out, for whatever reason.

No, as long as you have a 626s on Cricket, it should work. (Besides, I think Cricket is running on CDMA anyhow, though I might be mistaken.)

It's actually a 625 from Cricket that I'm using but it's considered to be the same as the 626. Cricket is using ATT's GSM network. I really hope I can enable LTE connectivity.

Well, that's probably what your problem is. After following the instruction outlined in the post (on my HTC Desire 626s), I've not encountered this. If everything else is the same beyond that, it's the only option.
PLEASE check that you've followed the instructions perfectly, especially steps 4 &8.
If you're 100% sure that you have, it may just be that the 625 on Cricket is somehow incompatible here.
At any rate, I can only help with what I have, and I have a 626s. If the exact same methods that work with my 626s aren't working on your 625, I can't do too much. Sorry...
If I can help anyway otherwise, let me know.

I used a Cricket 625 with the 626 ROM. Worked fine with the AT&T (StraightTalk) SIM.
A word of caution: this phone has very little room for much of anything. The stock ROM completely fills up the phone after all of the updates download (under Lollipop). This ROM gives you a bit of extra room, but not much.
I'm very happy with my no-ad Moto G5+ from Amazon. At $219, it's an incredible value. The bootloader is unlockable, and it's fairly "current" with nougat on the phone. Oreo is already in the pipe, and you can always switch to more custom ROMs after the Oreo updates quit coming.
With all of security issues plaguing phone users, old phones that can't keep reasonably current need to gracefully fade away.

Exactly the reason why I would like to run Android 6 on this phone so I can use adoptive storage
I also have trouble opening the APN settings after flashing this rom. Most of the times the phone shows me this "Select your carrier" screen. When I select my carrier (Telfort), internet works but after a reboot I have to choose my APN again. Anyone knows how to get rid of these preset apn settings ? (I tried these instructions for editing the build.prop to get full access to the APN settings. All suggestions are welcome, thank in advance !

I think I used a ROM called "AdvancedStock626_V5.zip". It's a bare-bones ROM, and I was able to manually set the APN.
You have unlocked your phone, right?

Yes, the phone 's bootloader is unlocked. I assume you mean this rom:

Whoops! I was wrong on which I flashed. My apologies....
I couldn't get the Advanced stock to "recover" with TWRP. Instead, I installed the debloated Sprint_Stock_MMDB from this thread:
https://forum.xda-developers.com/de...-flashable-stock-htc-626s-debloated-t3293602/
I had LTE, or at least I thought I did. Everything seemed to work with my StraightTalk (AT&T) SIM.

Maybe this Sprint Rom doesn't support European LTE frequencie, I bought this 625 phone from Cricket last year when I was in the States. I see that I'm 3.5G now which is fine by me. One thing that concerns me is that the data roaming icon is greyed out. I'm flying to another EU country next week, does this mean I don't have internet abroad? I modified ro.com.android.dataroaming=false in build.prop into true, still can't select data roaming. Anyone know how to fix this ? Appreciate all the help!
