[Sprint HTC One (M8)] mswlogo:
My "3G of death" was definitely not the network. New phone is 100% better and I still had the old one I could compare side by side.

I could not even activate the broken one in a 3G only area. Another symptom (which is why I keep thinking it was firmware or configuration)

is the broken phone would, within an hour or so, Grey out all the "Roaming Guard" options. 4 days later on the replacement phone they have not

been greyed out. I think this is an early symptom. Because those were locked out on the broken phone before "3G of Death" set in.

It behaved like it thought it was roaming on something it shouldn't or that I wasn't allowed to roam. Which made it almost look like an account issue.

I even tried reactivatng the broken phone after I got the new phone working and it immediately had issues again. It could only be activated over WIFI.

Phone calls in 3G only areas would consistently drop after like 30 seconds.

Another thing it may have been doing is THINKING there was a cheaper or faster network available, then attempting to use it and fail and then fall back.

It was constantly "Connecting..." to something.

It was often showing only 1x (which is accurately displayed on BadBoys ROM).

Even with 1x showing up as soon as you went to use Data it would drop Data completely.

It was really messed up.

that phone sounds like this one i have everything would go leaving a white x and no signal bars ..then some roaming...no calls go thru nor received yet they say its the network and they are working on an update for it...its not the phone..hmmmm...when u took it to the store how did they determined it was messed up??..cuz the assholes at my store said there was no way to test...myphone wont connect to 4g and im in a 4g area...also at the store the m8 in the store is on 4g mines is right next to it..no 4g...same model "april 1st" and has lte
[Sprint HTC One (M8)] mswlogo:
I must say the service guy at the Sprint Store was quite reasonable (2nd Store).

Luckily the technician and a co-worker of his, owned the same phone and he could tell something wasn't right.

We were in a 4G area so the phone WOULD work at the store (which I thought was gonna be a huge issue for me),

but it was not running as good as the ones on Display.

So it was his idea to go outside with stronger 4G. Put his phone and mine into Airplane Mode.

Then we flipped both On. His immediately locked on to 4G.

Mine took forever like it was hunting and I if I recall wouldn't even go onto 4G. I forget exactly now.

But it was clear mine was not behaving normally. It was 10x worse if I was in 3G only area.

Doing the Airplane thing (his suggestion) amplified it was behaving incorrectly.

Goto a Sprint Store and Compare to other phones. It's the best way to get "Network Issues" out of the equation.

If I let the phone sit idle and brought up Advanced Signal Status. It would look nearly identical next to a working phone.

Once I'd go to actually use DATA things went bonkers even with Advanced Signal Status (Free for Google Play). You'd see it switch to 1xRTT.

I wonder if there is "Load Balancing" going on. Kind of like Gas Rationing based on Even and Odd License Plate.

And phones with an EVEN "ID" go on this channel or tower and those with ODD "ID" go on this other channel or tower.

It could be load balanced across 16 channels and 1 out of 16 there is a bug. Or 1 out of 32 etc.

Because it seems like a bunch of us got hit around the same time frame. But it didn't effect everyone.

Seems odd for hardware to fail that consistently between a segment of users.
[Sprint HTC One (M8)] DruoGaby:
well the people at my store sucks!!!..my phone has seemed to regain lte but nothing is loading...lets see how long this update takes
[Sprint HTC One (M8)] graycorgi:
I flashed my phone to the Harmon Kardon ROM and started noticing the issue where my phone did not want to get rid of 3G. Turning off the Sprint Connection Optimizer seemed to bring the performance back to the way it was before I flashed the ROM.
[Sprint HTC One (M8)] DruoGaby:
so after goin over some trouble shooting over the phone...the local assholes at the sprint store could have done that..now i have to drive back there for a new phone!..this one is not connecting to lte after all..dunno what went wrong
[Sprint HTC One (M8)] dandan2980:
Just had these issues after one day of owning the phone was good for a day I rooted soff flashed the HK Rom and that's when it went south this morning was good then all of a sudden I couldn't even make a phone call kept on roaming lte would not connect and on 3g the data wouldn't even work . I did everything I could think of but it wouldn't stop acting up so I took it to Sprint right after work they tried blaming the towers there is a tower right behind the store had to argue with them and convince them it was the phone finally they switched and instantly lte was on again. I wonder if it has something to do with rims we flash cause I'm rooted ,soff ,stock Rom and I'm staying put cause this afternoon was awful I swear it took 10 tries to even make a call
[Sprint HTC One (M8)] DruoGaby:
same thing man tmr im goin in! to get a next one man...i went today and they hit me that same tower **** im not s offed...but im definitely goin in tmr..i already showed my boy who works there!
[Sprint HTC One (M8)] dandan2980:
I took the phone in rooted and soff I didn't tell them that they just messed with the update crap and finally gave in total BS I was pissed off but still kept myself calm
[Sprint HTC One (M8)] DruoGaby:
imma be like u..no rooting...just run it!!..lolol
[Sprint HTC One (M8)] dandan2980:
I rooted and soff again I just didn't flash any roms. Xposed and viper 4 android is all I installed and a couple team blackout apps this phone is fast and battery friendly stock
[Sprint HTC One (M8)] DruoGaby:
im stock and it happened to me..so i dont think it matters...lol im not even s offed
[Sprint HTC One (M8)] FlowingAway:
I'm s off and running stock rooted hk .13 version and the .13 firmware. Mine has settled down and is working ok now, just waiting on the 800Mhz to be fully implemented. My recommendation is to flash a full firmware a few times, flash a corresponding rom, and do the ##72786# trick a few times and let the phone activate, update profile and prl itself when it restarts.
[Sprint HTC One (M8)] FlowingAway:
But it's also possible to just have a bad device too. My first one was dropping everything no matter what, no root or S off at all, just straight up stock and totally jacked up lol
[Sprint HTC One (M8)] DruoGaby:
but mines dont wanna connect to lte at alllll..i dont even have data on 3g an error comes up

worked great up until last night
[Sprint HTC One (M8)] FlowingAway:
When I took my first one into the store the tech support guy fiddled with it for 2 hours. Reset everything, blah blah, and when he compared it right next to their fully working display model he finally had to admit it was indeed messed up. Hopefully that will happen for you tomorrow. It seems like that's the only way for them to truly admit it and get you a new one.
[Sprint HTC One (M8)] dandan2980:
I was getting the error message also something like cannot establish data connection Lte_error code mm65335 something like that but it was pissing me off
[Sprint HTC One (M8)] DruoGaby:
yeaa same message here man..i cant wait till morning to get this out od the way
[Sprint HTC One (M8)] metalfan78:
I get that message at least 10 times a day.
[Sprint HTC One (M8)] drewtorrespr:
My friend I have Harmon Kardon edition and I actively looked out for the issues that other M8 owners where experiencing. and lo and behold the issue began cycling itself on my phone but no so horribly...I have a dirty feeling its a combination of things. First off the most pain in the ass aspect on my phone to me is Sprint Connections Optimizer. Turn that crap off if you wanna keep it from automatically jacking up connections. Next thing is to go into "Settings" then uncheck everything towards the bottom. Go to "Roaming Guards" and uncheck every freakin thing there.....see if that helps from everything going wonky...or at least helps to maintain an LTE signal for most.....It's the only thing thats helped maintain the phone from going haywire...dont worry about roaming cuz u can't do **** on it anyway. On Network Mode play with LTE/CDMA or Auto and see how it goes.

Next issue is on regular power saving mode the phone is shutting off the connection on its own. Basically for battery savings....I'm only guessing that a combination of all the checked boxes, connections optimizer, and the phones own software to want to shut off data when the screen is off is causing a major clusterF.......could i be wrong, maybe...but give it a shot my friends. If I'm right then sprint and HTC need to address the software that was loaded on the phone as it is. I still notice the hang up and the cycling it goes thru to maintain an LTE signal....I Just wish that CircuitSwitchFallBack was eliminated and Qualcomm separated the 3G and 4G radios. A lil more development into making more efficient LTE radios would have gone a long way.......CUZ I HATE CSFB
[Sprint HTC One (M8)] mswlogo:
I agree with the settings you mention and they do aggravate the issues. But they are not the root of most peoples problems with this phone.

CSFB is a good part of it. Plus flat out broken phones (either by a corrupted update/config that a normal user cannot clear or simply a faulty radio or antenna).

So does the Verizon Flavor also have to do CSFB? I don't think so. CSFB isn't a QUALCOMM limitation/fault it's a choice Sprint Made to implement Spark.

I think most would be thrilled with stable 10Mbs LTE, no Spark and Simultaneous Voice and Data. That the M7 generation had.

The M8 is better at pulling in LTE in general though, I assume because of new bands available that are either closer or penetrate better. Not because of "Spark".

Sprint did this so they can claim the "Best of something". Rather than try to make their network reasonable for most of their customer base.
[Sprint HTC One (M8)] DruoGaby:
well im finally back home after alll day with a perfectly working phone....was so crazy..the one they swapped me with wasnt working either..so they had to get me a next one!...lolol..im good now..gonna update and such
[Sprint HTC One (M8)] parmend:
How do we know if csfb is fully complete
[Sprint HTC One (M8)] aackmann:
Sorry, I'm jumping in kinda late here, but I've had this same weird radio/antenna issue with the M8. It's really making me mad now too. I just got my 3rd M8 on Monday afternoon, everything was perfect for the rest of Monday, Tuesday, then Wednesday on my way home from work my phone started again with the signal loss, inability to make calls, texts would come through every so often, but not regularly, and no data whatsoever. Every so often data will connect (never LTE) and then will cut out again. My girlfriend also has an M8. Hers was acting up a little yesterday with the same symptoms, but hers is fine today while mine is still not working. I live about 18 miles from where I work and it happened in both locations and on my way to work today so I find it hard to believe it's a network issue. I just can't believe I may be going for my 4th device in like a month! I'll be stopping at the Sprint store in an hour when I get off work. Ugh.
[Sprint HTC One (M8)] metalfan78:
I have experienced the same issue. Sprint could care less. I always get the 'the towers in you are are being worked on' bs. So apparently every tower where ever I go is being worked on. Yea right. Trying to get a replacement device is frustrating.
[Sprint HTC One (M8)] aackmann:
So far it really hasn't been difficult for me to get the replacements, it's just a pain in the butt. I have to drop it off at a local repair store for a few hours so they can see that it's jacked up, then I have to re-activate my M7 for a few days while I wait for the replacement M8 to be shipped to the store. I'm waiting now, so probably Monday or Tuesday my 4th M8 will arrive at the Sprint store for me to go pick up
[Sprint HTC One (M8)] metalfan78:
4th? I would be demanding a different device after 3.
[Sprint HTC One (M8)] Jerz201:
That's unfortunate. The phone is pretty spectacular overall. Some of the network hiccups I've encountered I chalk up to Sprint's network, not the m8. I've had some instances of LTE switching to 3G, back and forth. The next day I'll be in the same area and LTE would remain solid.
[Sprint HTC One (M8)] scott_0:
seems more of a Sprint service issue than an M8 hardware/software issue, my S4 while not a tri-band phone was having some issues staying connected to 4g at times, its just more pronounced with the M8, Ill give it to my 14th day before I decide if Im returning it
[Sprint HTC One (M8)] mjs2011:
If it gets really bad definitely take it in. My 2nd device is night and day compared to my 1st device.
[Sprint HTC One (M8)] scott_0:
yeah seems pretty good now, I was having some data issues, then did the ##72786# and all has been really good the last few days. I love love love this device and hope it works out

[Sprint HTC One (M8)] mjs2011:
nice! Yeah I tried that as well and it didn't work. That's when I figured I must have had a lemon.

Agreed. This phone is fantastic! My first HTC abd I'm very pleased.
[Sprint HTC One (M8)] mswlogo:
Just for the record I have not seen nearly this level of discussion

Of network issues on the S5 (same chips, probably same firmware, same towers).

I've been reading every post on both forums for past few weeks.

I'll be putting my M8 on ebay soon unless the S5 has a melt down.

Just don't trust it.

If you google network issues on M8 vs S5 you'll get night and day difference in discussion.

Not saying S5 is perfect. But for every S5 "network issues" there are 10 M8's.

Unless M8 is selling 10x more.

Hard to say if it's a bad batch too.

Could be just an option that's turned on in M8 that some towers don't handle well.
[Sprint HTC One (M8)] mjs2011:
Even going through what I went through having to get a replacement m8, it's still rather go through that than be stuck with Touchwiz. I'd even consider going the iPhone route over the s5.
[Sprint HTC One (M8)] dandan2980:
Development for the GS5 on Sprint doesn't even exist lol I wouldnt do it if I was you you will regret it. And I also would choose an iPhone over the GS5
[Sprint HTC One (M8)] scott_0:
I'm the same way, even if this phone doesn't work out for me and I return it, I refuse to buy another Samsung device, l haven't sold my S4 yet so I'd go back to that regretfully

[Sprint HTC One (M8)] mswlogo:
I don't see the big deal about Touchwiz. You click an Icon and it Launches. You flick a page and get more Icons. You drag Icons around. You add Widgets.

What is most annoying (and I'm not sure if I would call it TouchWiz). Is the Settings stuff. The Quick Menus are not as Nice as HTC. Nor is all of Settings.

They added this layer of Icons above it with rather generic names and it's hard to find the setting you want. Certainly annoying but not a deal breaker.

And if you like Blink Feed nothing comes quite close to that.

You can run Sense 6 with Blink Feed on any KitKat device. However dynamic Icons (like Unread Email Count Bubble) does not update.

It runs absolutely perfect other than this issue and installs very cleanly. If they can fix that issue I'll probably run it.

You can also run other launchers as well.

It has no effect on Settings and Quick Settings which isn't technically "Sense 6" but is part of the HTC way of doing stuff and closer to AOSP.

Email looks and feels very much like HTC. As well as contacts. But the Phone UI is goofy. Prefer HTC on the Phone.

I think some people label "TouchWiz" as all customizations the Samsung does and "Sense 6" everything HTC does.

That argument I can understand. And I prefer HTC overall package.

But the launcher itself is such a small piece of the whole package. And technically Touchwiz is just the launcher.
[Sprint HTC One (M8)] metalfan78:
I have never had a problem with TouchWiz other than samsung's choice of colors, and sounds. The ui sounds are easy to change though.
[Nexus 5 Q&A, Help & Troubleshooting] georgemv:
Has anyone found a way to tell the radio to allow 3g or better connections?

My carrier has crappy voice quality over 2G and during the N4 days I used to set 3G only.

Now with the Nexus 5 I don't want to loose LTE connectivity, so I'm looking for a way to tell the modem to use UMTS or LTE connections only.
[Nexus 5 Q&A, Help & Troubleshooting] emmanuel_baez:
I don't believe there is any mod for this as of yet. You'd have to lock to wcdma (hspa+) or leave it as is with edge/wcdma/lte. The only other thing i could think of is some sort of apn configuration to achieve your desired result. You would have to speak with technical support of your carrier to see.

Hope this helps :)

Hi al, I don't what I done but my s2i9100 is stuck at Cwm recovery. How can I get it to boot up etc? I tried wiping cache, factory reset etc and still can't get it to boot past CWM recovery. If I download your neatrom i9100XWMS3 v6.2.zip an put in on a sd card and into my s2 and then install from sd card on CWM recovery will it boot up then? Thanks

[Galaxy S 4 Active Q&A, Help & Troubleshooting] solokiller11:
Hi i just read about the i9295 and the i537 and they are the same device accept the different in the frameware version (the i9295 - 4.2.2, i537 - 4.4.2).

so i have the question can i install the i537 4.4.2 stock rom on the i9295?

and if not i'll be happy if you can explain why (just so i can understand).

thanx ahead! :laugh:
[Galaxy S 4 Active Q&A, Help & Troubleshooting] Devo7v:
While the i9295 and the i537 have the same hardware, they have different software. More specifically, the i9295 has an unlocked bootloader while the i537 has a locked bootloader. What this means is that the i9295 is able to flash/install a custom recovery, custom kernel, and custom ROM while on the i537, in order to flash anything it must be signed by Samsung. Only official firmware is signed by Samsung, so there is no way to flash a custom recovery or custom kernel. There is a way to flash custom ROMs, but that's not important here.

To answer you question, theoretically you could flash the i537 firmware on your i9295, but you will most likely end up with a bricked phone because bootloaders are only compatible with their intended models. So the i537 bootloader will only work with the i537 and will brick the i9295.

If you still really want the i537 4.4.2 firmware on your phone, I'd be more than happy to trade my i537 for your i9295. This is a great phone and works great in every respect, I only wish it had an unlocked bootloader like the i9295. If I could do it all over again I would have bought the i9295 instead.

EDIT: I think [MENTION=5150212]mythi[/MENTION] is working on a stock 4.4 ROM for the i9295, you might want to ask him about it.
[Galaxy S 4 Active Q&A, Help & Troubleshooting] solokiller11:
Hi thank you very much for your answer it helped me a lot.

and about the locked bootloader, are you sure that it can't be revert?

and one more thing i bought this phone like two weeks ago so what is the best custom rom for now? (i saw only the carbon rom 4.4.2)

and one more question, if the i537 4.4.2 is signed by samsung but with locked bootloader and the i9295 4.2.2 is also signed by samsung and with unlocked bootloader so cant i just flash back the i9295 framewere over the i537 framewere?
[Galaxy S 4 Active Q&A, Help & Troubleshooting] Devo7v:
Once you have a locked bootloader, the only way to get another bootloader on the phone is to flash one that has been signed by Samsung. Samsung uses a different signature on unlocked bootloaders, so there is no way to revert.

I don't think you really looked? I just opened the Development forum and found the following on the first page:

[S4-I9295● KK 4.4.2][05.05 M1][SOKP》》SONIC OPEN KANG PROJECT][AIO][Weekly Builds]

[Rom] Updated [Unofficial] Carbon Rom 4.4.2 based on CM11.0 [24.04.14]

In the Original Development forum there is [ROM][Unofficial/Experimental][Android 4.4] CyanogenMod 11.0 for SGS4A (int'l). It's under constant development and I hear good things about it, but again, I have an i537 so I can't try any of these.
[Galaxy S 4 Active Q&A, Help & Troubleshooting] solokiller11:
If Samsung doesnt sign unlocked bootloaders so how the i9295 have one?

and thank you for the custom roms	;)
[Galaxy S 4 Active Q&A, Help & Troubleshooting] Devo7v:
The just flash it to the phone. To simplify the way the bootloader works, it is the first thing that loads when you power on the phone, it then tells the phone what other pieces of software to load (aboot, sbl, kernel, etc.).

With an unlocked bootloader, it does just that, it loads the next piece of software during the booting of the phone. With a locked bootloader, the bootloader checks the signature of the next piece of software to load, if the signature matches the signature that the bootloader expects then the next piece of software loads. If the signature doesn't match, then booting stops.

When you flash something to the phone using Odin (currently the way you flash bootloaders), with an unlocked bootloader Odin will flash it, for better or worse. But with a locked bootloader, the bootloader checks the signature of the file you are trying to flash and if they match then it can be flashed, if it doesn't match then the flash aborts without any changes being made.

So, how can Samsung put an unlocked bootloader on the phone without it being signed? When you start with empty hardware you can essentially put any software you want on the phone, there is nothing there preventing it, but once you put a locked bootloader on the phone if will then check every single piece of software you try to flash to the phone.

TL;DR Think of the hardware as an empty room. You can put anything you want in the room to start with, but if the first thing you put in the room is a door with a lock, then the only things you can put in the room from then on are things that have a key to that lock.
[Galaxy S 4 Active Q&A, Help & Troubleshooting] solokiller11:
Hi man Thank you very very much for the explanation about the bootloaders and i think i gonna install the carbon rom :)
[Galaxy S 4 Active Q&A, Help & Troubleshooting] mythi:
NONONONONONONO ... never ever i say never ever repeat what u said in here ... flashing a other devices bootloader will destroy your phone and you will need something called jig to fix it ... this happens because every device that sammy realeses has a private key for certain partitions on the mmc like the bootloader the rbm etc ... flashing other devices partitions even if the share the same hardware (yes) even if they are from the same family will kill your phone and you will end with a paper that need 200$ service . i request you to edit your comment since alot of the people here are noobs or have little knowelge .
