Removing the ROM of an HTC demo unit AT&T - AT&T HTC One (M8)

Hello people
So i my problem is that i have recently baught an htc one m8 AT&T device . and i found that the android that it's running on it, is just for the demo units it's 4.4 kitkat , moreover i have also some issue with the hotspot option and the network choosing option, like i don't have the ability to choose which network to use 2G or 3G or 4G it's all the time 4G .and you all know that the M8 has got already the lollipop android version on April but mine still on it's demo android version
i have tried the hard reset but it did not work also the did the updates for AT&T apps also did nothing.
please if any one can help me out with a solution i will be more then thankful. also may you know that i'm not a professional android developer so if i goona need to have some files please provide me with them or their path

Was the phone advertised/described by the seller as a demo unit? If not, its obviously a fraudulent sale; and you should seek a refund or exchange, rather than messing with the phone any longer. This is not a fully functioning phone without significant mods by you, taking time and possibly even money.
Hard reset just wipes user data, and won't do anything to solve this issue.
Network type (2G, 3G, 4G) is locked out on the AT&T version, as is the WiFi hotspot. You may be able to unlock the bootloader and flash a custom ROM to make this a fully functioning unit. But you may also need to s-off the phone ($25 by sunshine).
Depending on your intention/response to the above comments, I'll be happy to help you more.

Thank you bro for your support. my problem is that i cannot go back to dealer because i'm not actually in the US and thing is i have contacted him by my brother who baught it for me from there, he said he didn't know about that problem till now ,he sent me some pictures of the other htc phones that he is selling and they turned out that all of them are just demo units and not for sell.
While i was looking on the internet i found that rooting my phone and installing a custom rom is my solution after all ,exactly as you said.

Not just any ROM. Since the device is on KitKat firmware, you will want a KitKat M8 ROM. Otherwise, you will have severe bugs, such as extreme long boot time (or no boot), or broken WiFi.

[Q] AT&T One X + Tethering with International SIM

Hey guys,
So I have a bit of a tricky question that I can't seem to find an answer for. My wife and I just move to Europe for work for 2 years. We had AT&T in the states, so my wife has an AT&T HTC One X+. We got our phones SIM unlocked before we left, and purchased French SIM cards that run on the Bouygues Telecom network. My phone (Lumia 925) can do wifi tethering no problem... My wife's on the other hand has issues. I keep getting the following error:
" There is a temporary network problem that prevents the enablement of the Mobile Hotspot function. Please retry later."
I have tried the following steps:
1. Rooting the phone.
2. Installing other hotspot apps (Both root and non-root)
3. Installed custom ROMs with hotfixes to remove AT&T data requirements.
I don't know if it's relevant, but when I do a reset on the phone, it doesn't automatically connect to Bouygues network for data. I have to manually add the APN every time. Once I do that, her mobile data works just fine, so I don't THINK that the APN is causing the problem...
Anyways, if anyone has an suggestions on how to fix this issue, I would be indebted to you... I've just never encountered this problem on any of my other Android devices and I have to believe that there is a simple solution to fix the problem that I've just not encountered. Thanks!!
I loved my international HOX, so when got dropped in water i said lets go for the ATT HOX+ that has LTE.
Big mistake! I have OP's same issue, im in spain and my provider is Movistar.
I bought it on e-Bay, configured all the APNs, I used settings from their webpage and also tried telephony.db values from an international rom, stock rom didn't tether.
Rooted stock (4.1.2 i think it was) still nothing.
Elegancia (4.2.2) ROM, still nothing.
Changed some stuff on the telephony.db, still nothing
Swapped the wifirouter.apk with the international wifirouter.apk, still nothing.
Nuked TetherGuard.apk, still nothing.
Installed Moto-X tether Xposed module, still nothing (probably cause it's for android 4.4).
I read that AOSP or Cyanogen ROMs don’t have this issue.
I also read that if you swap telephone.db from international version to USA version the phone goes into a reboot loop, [More Info].
I guess the solution lays in something similar to the Moto-X tether patch, but i don't really have the time to fork the project, and try to get my tethering working.
Hope someone can give us a hand, im sure there are at least 5 more people in this same situation.

[Q] Best way to Use LG G3 Without Service

I think this is the first time I have posted, even though I have been using xda for years. Anyway I bought this LG G3 from Swappa and low and behold it has an unpaid bill tied to it and cannot be activated with Ting and I don't have a Sprint account. I have no need to activate it since I use WiFi for everything. So I decided to keep it since I got a good deal and didn't want to wait to return and buy another for $50 more. Right now I am stock and have not attempted to root the device. I have rooted every other phone I have had, due to the software being really bad or outdated. This is the first phone I have had every had where I actually like the stock ROM that came with it(probably because of Lolipop and LG really taking Googles design sense.
My problem is that even though I keep the device in Airplane mode with WiFi on, the device of course attempts to connect to a network every time I power on.(I have to click emergency call and then home) Also the Sprint Data optimizer is using about 20% of my battery, probably searching for service it will never find.
So my question is, If I do decide to root the device. What would be the best ROM to use for my situation of no service? I prefer Stock Roms unless AOSP has a remote control, which I don't believe it does. Also do I really need to care whether I am on zv8 or zv4 since I do not have a connection to a network?
Also. Is there anyway to possibly get T-Mobile service on the LG G3 Sprint Variant? Even if it is a slow data connection.
Thank you if anyone has any answers to any of my questions.

You can flash this ROM for GSM and check HERE for the remote stuff and other mods and tweaks.

Purchasing LeEco Le Max 2 - AT&T

I am thinking about purchasing the LeEco Le Max 2 to use with AT&T. I've been reading on XDA and it seems like the US variant is the x829 one. I'd love to have the 6GB RAM model but the x829 does not have 6GB RAM.
Is there anyone here using the 6GB RAM model without issues (especially getting LTE to work) on AT&T? or maybe T-Mobile? If yes, which hardware variant do you have? The x820/x821/x82x...etc? and from where did you buy your device? Please share the full link if you have it.
Also is there a guide that shows which bands each variant supports?
Thanks guys, really appreciate any feedback.
Google "le max 2 x829 128gb" you'll find many places to purchase a 6gb/128gb x829 for as low as $245. I have the 4/64 x829 running stock rom on T-mobile with full coverage on lte. To my understanding the only band that's problematic is band 20 which we dont use in the united states. I bought it for my wife who wanted a rose gold model which is not offered in the 829 but I forced the gold 829 variant on her because I wanted direct access to the 829 rom so I can do some deving on it. I'm ordering a rose gold 4/32 for her Thursday for $193. When it arrives I'm going to clone her rom directly to the 820 then take over the 829 and have some fun. As for the 829 we currently have she loves it, loves the screen loves the camera loves the new ui (I hate it but to each their own). Call quality is great, volte works and even wi-fi calling on tmo works. As a comparison my wifes last phone was a Moto X 2015 (xt1575)
@castuis Thank you for the information. Do you mind if I ask from which website/seller you brought the phone? also where are you seeing the 6gb/128gb for $245?
Got mine from tinydeal. Ali express for the 128gb but they bumped it up to $259 about an hour ago, plus you couldn't pay me to order from them, made that mistake a few years back.
I am awaiting a silver 6GB/128GB from coolicool.com.
My first order with them, but they have been conversing with me via email since I changed the shipping address.
I 'should' have it with the next week? I hope it arrives and has a good fingerprint scanner?
@fcreeves I'm thinking about ordering from coolicool as well. Did you order from the Hong Kong warehouse or the Europe warehouse? Can you please let me know the condition of the phone when you receive it and which variant is it? x820 or x821 or x822 or x829?
A friendly word of warning. Success with the phones on T-mobile is not an indicator of how well they will work on AT&T, even though they are both GSM networks. For example, if voLTE is important to you, you are very likely not going to get it on AT&T. It is not automatically provisioned on AT&T, unless they know your phone intimately (and they don't know the Max 2 from a tin can and a string.) The first line of tech support refuses to even enable it on "unlocked" phones. There's also no means for WiFi calling, via an app or otherwise, unless you count the microcell boxes.
I'm tempted to call "BS" on anyone who says they are using these features on AT&T with these phones, based on the time I have spent on the phone with tech support..
Under the right conditions (read: areas), the phones work great on the AT&T network. Fast LTE data, and decent call reliability. But if if you want the bells and whistles, and enhanced reliability, the Max 2 can't deliver what the more mainstream brands can on AT&T. Even when right next to a tower, with the Max 2 showing full bars, I am unable to make calls, while every major branded phone brought into that same area has no problems. So something isn't 100% with these phones.
@RandyT2 I really appreciate the feedback.
@fcreeves, I'll be waiting for a feedback from you on the phone condition & fingerprint scanner.
I do have X829 64GB in the Boston area and I just got the Straight Talk AT&T nano sim yesterday. Popped it in, transferred my #. Had to change my APN in order to get LTE working, but everything seems good now. I don't know about VoltLTE, but everything else seems OK (for the moment).
With Straight Talk you have the option to go either Sprint/AT&T/T-Mobile or Verizon. I was using AT&T on my Nexus 5 so I thought I'd stick with it. Not sure if Verizon would be a better choice, but I didn't want to wait for them to send me another sim to test it.
The main issue for me right now is getting the fingerprint sensor working and rooting/flashing my ROM which seems a daunting task.
@Wagmans thank you for your feedback, not sure why many have issues with the fingerprint scanner and some don't have issues at all with it. It would be good to know if it's a hardware or software thing.

Can you give me some idea as to the ROM and Baseband version of the X829 phones you have? I really need WiFi calling, if I wish to keep this phone (which I do), and the way I understand that the T-mobile Wifi calling works is that the ROM detects that its an option based on the connection with the carrier, and the option just appears on the phone.
I'm ready to ditch AT&T because I have a fairly unique situation which makes the phone virtually useless to me without WiFi calling. But I need to make sure that I'm not switching, just to have the same issues, or to find out that only the X829 version supports it.
Thank you!

I think it's more of a software thing. We'll know once I root/flash it if that's the case. The root/flash process for this phone seems so involved. A little overwhelming- I hope I don't brick it.

It's too easy to flash TWRP, flash a new ROM, root and do all the things you need with it. This phone is practically unbrickable as you have a guide that teaches you how to unbrick it. Still, it's as easy as it gets to play with it.
@Wagmans please keep us updated if you get the fingerprint scanner to work
Yeah keep us posted. I'm interested in this phone. I have a Samsung S5 which I love and still use with no issues, but I'd like to have dual sim and have redpocket 99$ per year plan and Freedompop free data on the other. This set up will end up saving me hundreds of $$ per year.

Or a human thing. I got my wife the x820 in January. Immediately flashed TeamSpain's CM13 understanding the stock firmware had fingerprint scanner issues. All that, and only to learn she rarely gets the phone to accept her print, but when I pick it up it works every time. So there is obviously a human print component in the equasion that determines the FP scanner works, in addition to hardware & firmware.
I pulled the trigger on the TinyDeal 64 x829 today for $202 for myself. Leaving the Moto G4 xt1625 behind as a backup. I'm sorry, 2 GB RAM on my Moto G4 is insufficient. We expect our phones to be computers, and they are, but we'd never expect to run 2GB RAM on a modern day desktop. I'd really like to see a 32GB model with 6GB RAM.

I'll fool around with it. I'm still confused as to exactly which ROM I should flash and still have US Straight Talk/AT&T compatibility? Would the stock Indian ROM work? How about the Chinese? I don't know what the differences are (needs to have English, obviously). It would be nice to flash a stock ROM and be able to get the software updates from LeEco (as opposed to being locked out with my modified 16s now).
Oh, and as far as I can tell, VoLTE/MMS is working for me on AT&T in the Boston area.
So to sum up, everything is good for me on this phone except fingerprint and new/better ROM. I'll see if I can resolve that once I get some answers as to which ROM to flash.

I'd say if you want updates from LeEco, then don't flash. IMO security updates are really what's at stake.
Ideally:
(1) you want a stable rom with all the bells and whistles to make you happy, and
(2) the dev is updating the rom every MONTH with google's security patches.
But we don't live in an ideal world. TeamSpains CM13 rom may be the best google stock-like rom out there, but it appears not to be 'updated' anymore. It's very stable and everything just works. So from a performance standpoint, it's great. But from a security standpoint maybe not. But then again, branded carrier phones sometimes never get security updates

As far as I remember, the Chinese one has no limitations such as SIM1 4G and SIM2 only 3G or less. I'm using the Chinese one for quite some time and I'm happy with it. The Indian ROM has Play store but will add an encryption to your phone. In case you want to flash something again using TWRP, you have to format internal memory. The US version that was leaked 3-4 months ago had a limit of 4G on SIM1 only and 3G on SIM2.
Once you will flash the ROM, don't root it, otherwise you will not receive updates and you have to flash the new official stock again when it comes out. Search "manual gapps" to install Play Store on it.
Any ROM has English on it, even the Chinese, and it's not "translated"
About the AT&T compatibility, I'm not so sure. Maybe somebody from US can help on that matter.

Data Connection Partially Lost on Unlocked Sprint M9 after Official Nougat Update

Hi all, sim unlocked s-off sprint m9 used to work well on android 6 with official rom. But until the phone was upgraded to Android 7. Data connection stopped working for one operator (NOS in Portugal). However Vodafone works well.
Tried different roms and apn settings, same at all. Data connection does not work on NOS operator.
Does anyone have similar issue and of course any advices?
Thank you all.

Why sim unlock a Sprint variant and not an AT&T or T-Mobile which already support GSM?
did you find a solution?
i have exact same issue.
bought one m9 from ebay with sprint (651) firmware on.
lte was working fine in israel (1800 2100).
after nougat im only getting 3g.
it makes sense that i cant use those bands (1 and 3 i think) on a sprint device.. but it did work with marshmallow
Same problem in the USA
I have (nearly) the same problem in the United States with a Sprint CDMA version of the One M9. The main difference is that my data speed is even worse than 3G, around 10-20 Kbps. Occasionally, I get faster speeds, but I haven't been able to figure out if it is location-specific (but always away from home and work) or due to some other characteristic.
The phone came brand new in a retail box from an eBay seller. It worked as expected for 1.7 years. The OTA update which installed Android 7 (aka Nougat) in early 2017 resulted in the very slow data speeds. WiFi is unaffected, but data is so slow that I cannot reliably send or receive MMS; Google Maps says that I do not even have a data connection for traffic info.
EcoMobile (my MVNO provider; I still have a sprint email address, so I know who is actually providing service) could only suggest resetting my phone; did this twice with no change in operation (but several of the programs which automatically re-installed themselves operated differently, including GMail no longer providing auto-complete for addresses).
After literally 2 hours in chat with htc, they told me that my MEID indicates my phone was "made in Taiwan". I took this to mean that: 1) the person I was chatting with had poor English skills (because aren't they all made in Taiwan?), and 2) my phone is gray market (meaning it was not imported into the country via official channels, even though the manual was in the American version of English).
I came to XDA looking for an answer, too. I was mildly surprised to see that this topic was at the top of the list for the One M9.
The best solution for my situation would be the proper ROM for my phone, but I don't know how to figure that out from the MEID. htc USA says they cannot help me with this.
I could even go back to Android 6, but I do rather like the new features in Nougat.
Alternatively, I could root the phone and install a 3rd party ROM, but I still need to know how to choose the proper one for my phone.
I hope this info finds its way to a helpful expert.
Regards,
Jeff

Galaxy S9+ SM-965F/DS T-Mobile WI-FI Calling / VoLTE issue

Hey everybody,
So recently i bought this international unlocked Galaxy S9+ (SM-965F/DS Exynos processor) off Amazon and it's great, everything is fine with the one major exception being that at home my signal is pretty poor and i get extremely delayed text messages coming in and calls taking forever to dial out or failing to connect. Not a problem, i'll turn on Wi-Fi calling, right? Wrong, option isn't available, some detail: I'm in the US on T-Mobile, updated to the latest Pie OS update, i'm very tech-capable and used to do tier 2 tech support for Verizon. Long story short, I've tried everything in the book including FDR and fresh setup as well as clearing system cache etc. and it's looking like the ONLY solution to get Wi-Fi calling (and subsequently VoLTE that i didn't realize wasn't enabled until researching and checking myself) enabled is to flash the ROM with a T-Mobile OS. Unfortunately i'm coming up negative trying to find the firmware for this phone. Plenty of resources out there for the SM-965U(Snapdragon), but none for the SM-965F(Exynos) as of yet as far as i can tell (and before any ignorance jumps in here as i've seen on other threads, NO the SM-965U software will NOT work on this model phone as it runs a different processor, non-Snapdragon Exynos chipset)
So, that all being said, is anyone out there working on a fix for this, is it likely i'll ever get a fix for this, and/or is the fix already available and I've just completely missed it? Any information or help would be greatly appreciated. Thank you for your time and consideration.

I'm currently researching the very same issue... So far i hypothesize , with no knowledge, that if it is rooted, you can then change the csc settings and configure it for TMO, thus enabling WiFi calling. If someone can confirm, that'd be great, otherwise i'm trudging slowly to verify.

Well i looked at this and it looks like a non-stock rom i'm sure wrought with problems that unfortunately is not helpful. My goal here is to have my phone work and continue to get standard updates with original and licensed (more or less) software and have it actually work. I'm not interested in a full OS replacement pre-loaded with a bunch of adblockers and other crap the designer thought would be useful, just want my standard features enabled and nothing else to change if at all possible. Also, if you believe my statement here is in error please explain, your one line really isn't very helpful, and nowhere on their website is there any description as to what tekhd detonator does / is supposed to do / what it will break. I'm certainly not risking bricking my phone when their own website says under all of its S9+ related material that it's for Snapdragon which the variant i have again doesn't use Snapdragon.

This is going to be a hassle trust me. even with the Snapdragon models from different CSCs VoLTE and Wifi Calling do not carry over. An ATT 965U would have to be reflashed with the TMobile CSC and USERDATA files to get access to TMobile features. U are trying to do this with an Exynos model. I think you would have to root and install a custom firmware that has the TMobile USERDATA embedded.
Good luck.
can the U1 be flashed to the verizon u firmware? i thought i read someone tried this, but suspected it didn't work because he had previously used the phone with verizon with the unlocked firmware...

You can flash the G965U onto the G965U1 and vice versa. It's been well documented that this will let us go from one carrier firmware to another as well as let us have the unbranded carrier firmware. The only catch to this is the bootloader version of the firmware your wanting to flash. The firmware one wishes to flash must have a bootloader version equal too (or greater then) what is currently on the phone.
If your trying to ask about flashing the U1 onto an exynos variant then the answer is definitely no. You can't flash firmware from a different model onto a different model.
