[Q] HTC EVO gets no mobile Signal but can do 4G - EVO 4G General

Hello, I've been trying to get my Evo to work but it seems to just have given up on getting signal. Before I start, I'll say that I dropped my phone in water, and did the rice trick. It worked flawlessly for a whole day, but starting last night, it just stopped getting signal at all. I am rooted, I was on Fresh 4.2.0 and I used ROM manager to flash. I even tried flashing the latest radio (EVO_Radio_2.15.00.11.19_WiMAX_27167_R01_PRI_1.77_003_NV_1.90.003.zip) and still have no luck.
Everything on the phone seems to be working fine except the mobile network and the GPS can't get my location anymore either. I just don't understand why it would randomly cut out and say there's no mobile network. This morning, I did a recovery to my restore point on fresh 4.2.0 and it worked for like 5 minutes and stopped. I just tried restoring to CM 6 and it still isn't working. I really don't think its hardware since everything else seems to be working on it. Do you guys have any ideas on how I can fix this? I'd really appreciate any help that could be thrown my way.
Thanks in advance

is it battery or ROM?

Morning everyone,
During last weekend I went to Birmingham and was using TomTom on my Hima (6.5 swampy ROM). While going towards Birmingham the phone was fine however once I got to Birmingham, it suddenly restarted. I thought maybe it crashed so I waited for the ROM to come back up.
Once it came back, it was running very slow. I switched on TomTom again and yet again it restarted. I again waited for it to come back on but this time when it came back on, it restarted again. It restarted around 5-8 times.
I was very frustrated since all my contacts were on the phone and not on the SIM nor I knew the direction to get to my friend house. I plugged the phone into the Ciggerete lighter (to charge it), and it worked fine for a while. Once I came back home I uninstalled few programs off it so that it can have some free memory. Yet it restarted again.
I then hard reset the phone yet it still getting stuck and getting rebooted at random times. I then downgraded it to 1.72 Old Original ROM with 1.7 Radio. At the time it worked fine so I updated it back to 6.5 with 1.9 Radio and so far it is working ok-ish.
My question is, is it the ROM or the Battery which is causing this issue? I mean it has been running stable until I tried to use TomTom for directions. I have tried 2 other 6.5 ROMs, yet after importing my contacts the Hima was running very slow. So I went back to Swampy ROM.
Sorry for a long post and I'd say some points it sounds random but that is due to very early time here .
Has anyone else experienced the same issue with their hima?
Regards
Jay

3G stops switching back after wifi?

This is a strange one. I have been using Fresh Evo 3.2.0.0 rom for almost a month and it works great. I wanted to try another rom so I tried the VirusRom... it was good but I liked Fresh better. So reflashed my Nandroid image and all was well.
But then I started seeing a lot of failed connections to the market and noticed that my 3G was not connecting. I live in Chicago so I am fully covered by 3G in this area, and even 4G in many spots. Usually when I leave a wifi area, the phone switches back to 3G almost instantly. But ever since nandroiding back to the Fresh Evo 3.2.0.0 rom, it only works after a reboot. As soon as I hit a wifi zone and then lose it, 3G doesn't switch back on.
4G and Wifi both work, but if I disable both wifi and 4g.. 3g doesn't come back without a reboot.
I've even switched off the Mobile network using the widget and the power button menu.. no luck. Only a reboot brings it back.
So then I even did the trick to get my PRI up to 1.40 and that worked fine. But no change in the behavior of 3G. When I reboot and 3G is working, it works great as usual. Just not sure why the switching no longer works. I even tried switching back to the rooted sprint stock rom.. same deal.
Anyone else having any issues?

yes, I have noticed this at times. Just happened to me. Failed connection when switching off 4g to 3g. Using fresh 3.2. But I noticed this as well on other roms. I had to reboot each time to get 3g working again. I also reset my data connection last night but it obviously didnt work.
I've been having issues with my 3G for the past two days. Similar story, I did and Nand restore and that is when it started.
I am getting an error code 67 everytime I switch from Wifi, 4G or even when I reboot to try and fix this. Usually if I let it sit it will come back, but the error message popping up is quite annoying.
Wish I had something more helpful to say, but I can just add that I'm having the same problems switching from wifi to 3g. Even after 3g turns on it will sometimes turn off again randomly and I will have no connection. I'm also running fresh. In addition my 3g signals are quite week. kinda a mess...
Weird. My phone did this today for the first time. The thing is, I've been on Fresh 3.2 for a month now, and I flashed the latest Baked Snack rom yesterday to test it out. It never did it while I was on Fresh, but today after turning off WiFi, it wouldn't connect to 3G for anything. No text or data transfer at all. After I rebooted it, it started working again, but my phone never did this while I was on Fresh.
I am having the same problem and I am using Fresh 3.2 as well. I did go to a different rom but then went back to Fresh's rom and that is when it starting happening to me. It will only pick up 3g now and then and even when it does my speed is super slow. Hoping someone comes up with a fix as I made my own post but no one seems to feel the need to reply to it.
Theories...
Same here. I'm on Baked Snack 1.7x
I know Fresh and Hero both use some of the same components. I flashed to Cyano and have had no problems with the 3G radio. It's very snappy switching on and off after wifi connects and disconnects.
I do know there have been one or two issues with the radio with people who are on the 3.28.651.x roms. (for instance, if you enable 4G then disable, sometimes it randomly turns off and on without you knowing until you restart)
So my guess is maybe the 3.28.651.x series is glitchy. You guys want to try going back to 3.26.651.6 and do some testing?
happened to me on stock. Had to reboot the phone to fix it.
This seems to be working for me today with no problems so far. I am wondering if a tower was down with Sprint putting up the 4g around my city. Will keep posted if it happens again but seems to be running like normal now.
This has to be network issues maybe the latest PRL.
Mine has did the same last couple days also on power on , it takes longer for 3G icon to kick in.
Signal flux has been occurring more then norm fast download - Upload speeds taking hit some parts of the day.

I am on 3.26.651.6 build and this was happening. I am no longer having any problems with this. I do feel this might have been a problem Sprint's servers were having. Seems like everyone started having the problem right around the same time.
It must be... Going to an older PRL didn't help, and there are a bunch of forum topics being created about this on other forums as well. Guess it's time to play the waiting game.
My issue is so bad right now even if I restart my phone, it doesn't even get data connection right away. 10 minutes waiting now and error code 67's keep popping up.
This just happened to me today. It took me awhile to connect the error statement to the fact the 3g didn't turn on after I turned off wifi. But I was able to press the 'data connection' button on the switchpro widget to turn 3g back on.

That is how I got it working a little bit last evening but as I said in my last statement it is finally working and has been all day. Not sure what the deal actually was as I did not change anything since 2 evenings ago. I am thinking that Sprint is doing something which is messing everyone up at one point or another.

[Q] Serious Signal (3G/LTE) problem (keeps loosing signal)

some background info.
I ran stock room for 3 weeks, then one morning the signal kept dying on me. it would turn on for 2 minutes then loose signal again. and they it got so bad that i couldn't even make a phone call.
so i did following:
* Reinstall room (using the settings option, and factory reset)
(still same problem)
* change new simcard
(same problem)
* then finally i sent it into service.
It came back working with stock room of course)
work done when it was in service (just a hard reset with computer, tested OK)
it now worked fine for a week, then i rooted, and flashed a G-flex room.
still works fine for 5 days.
THEN today the same damn thing happens again.
the signal drops in and out every 5 seconds, the phone gets insanely hot, and the battery drains insanely fast.
what i'v tried so far.
*Whipe dalvik cache and fix permissions.
*flash new modems. (two modems)
still same problem.
I really REALLY don't want to send it back in for another 4 weeks at the service.
Do you guys have this problem? i tried looking on google for people with same issue but nothing that relates to my model number: D_802.
can you guys helps me out?
I have the ls980 variant and get horrible reception after root. Replaced the phone and all was perfect until I rooted. Went back to stock but issue persists. Going to try and reload SW again and see what happens.

Serious signal problem

Hello, I would really appreciate your help on this problem I'm having.
My nexus 6p was working fine on marshmallow, one day I installed an ota update and lost signal, my phone showed no service, after that I spent a lot of time on researching untill​ one day I tried to restore an efs backup from someone else's phone and it was fixed, I got my signal back, the only problem is that the signal drops constantly which makes it unusable, sometimes I am on a call and it loses signal then comes back, I have tried everything from flashing stock, different radios, locking the bootloader, flashing chroma rom, changing radio bands...
I am getting frustrated, please help.
hey, tell me about that restore efs using someone elses phone. Where did you got it, can you help me? Im without service going crazyyy

Dead WiFi

My 6P's WiFi suddenly died on me. I've had this phone since 2016 and I've taken really good care of it. Things were working perfectly last Sunday when I was in some other city, but as soon as I returned home WiFi was dead. At first I thought it was a router problem so I reset it to no avail, since my phone wasn't finding any connections even though everyone else's could, then I tried turning it off but the problem persisted. Later I tried a factory reset, but that didn't work either.
Whilst my phone is rooted, I'm on stock ROM and I've pretty much used root solely for V4A/ARISE. I also haven't installed any apps that may overheat it, or that could cause some damage.
I've never dropped my phone and it's fairly well protected.
So, what the hell is going on? Do any of you guys have any idea?
