D802 no signal on any custom ROMs - G2 Q&A, Help & Troubleshooting

As the title says, I can't get any signal whatsoever on miui or aosp ROMs whatsoever. The only custom ROM I actually do get signal on is cloudy but I'm a bit of a flashaholic.
I've tried to flash the baseband for KK D802 hoping that would fix it but it didn't. Any ideas?

CyanogenMod has never been too accurate when reporting signal strength. Even though you'll have 4 bars on stock KK, you'll only have 1-2 bars on CyanogenMod or other AOSP based ROMs when in reality your signal is much stronger. Unless you mean you literally have no signal at all than don't worry about it.

No signal whatsoever. Tried to find networks manually in settings but it doesn't even search.

maybe you have damaged the file efs?

Do you have the correct APN settings for your carrier? If they are incorrect you will not get 4G, but I've never heard of not getting any signal due to incorrect APN settings.

Exactly, I'm not too worried about the 4g I'm just not getting anything on those roms.

Better signal unrooted

I bought my ns4g about a week and a half ago coming from a tbolt on Verizon. I got it at 8pm and had it rooted by 9. I immediately installed cm7 and have been using every nightly. My signal was horrible. I had nothing at work and barely one at home. It also would barely hold a wifi signal even when laying the phone right next to my router. I've updated my profile and manually put prl 60679 on the phone and nothing improved. The only time I could get 3g was using the Verizon hybrid prl ( I don't have 4g here). I called sprint and updated the msi? And the lady said I was in great coverage at work and good at home. The signal was so bad in 4 ours of the phone sitting in my pocket doing nothing I lost 50% battery everyday. So this morning I unrooted to take the phone back to sprint for an exchange. I've been using it stock for about an hour and now wifi is good even outside my house and I get 2-3 bars most of the time. Is there any reason why this would be? I have owned about 90% of Verizon's android phones so I'm not new to this, I've just never seen this kind of difference between stock and rooted. I think I will wait and see if it stays like this or gets worse now and switch to the 3d if it is still bad. I switched to the nexus s because I love plain android, butit was so bad before I couldn't even make phone calls or send text unless I got lucky and it would connect.

the only thing i know on the subject is i left my phone unrooted for a couple of days. never noticed a difference after rooting. seems to be many conflicting reports on signal issues when it comes to the nexus. i have generally lower signal (3g 4g wifi) than my evo. really hope its software related so i can get a fix.
Rooting doesn't affect the phone's radio.
Maybe the ROM was bad?
ive been watching my signal strength for a day and its usually around -86. my evo was always -90 or more
It could be the rom I just don't get it. I've never had a problem with cm7. I'm going to root and fund it stock rooted and see then maybe go with something else

damn i like soju 2.6 too. oh well stocks not bad either. i see theres 4 kernels to chose from and 2 are experimental
ok so i flashed my "out_of_the_box" back up and updated prl and profile and my status numbers are the same. i did notice tho that with soju 2.6 i was on evdo rev 0, and now back to stock im on rev A
now wtf? after i flashed a netarchy kernal (stable bfs 2.3.4) im on rev 0 again. what going on here?
Here's what I'm gauging my claim on. I live in a basement apartment so I get awful service anyway. But, on CM7 I can't make a call without it dropping, and mms is out of the question. On stock, I can almost always get through a call and mms sends no problem. I have an airave and its the same story on that. CM7 the mms just sits there with the icon spinning forever. Stock it sends almost instantly. I keep a backup of both and just switch between depending on what I'm doing.

My favorite quote "Engineers are educated beyond their intelligence." Ironically, I am in school for engineering
Now I have a problem. I rooted again and right now I am stock rooted. My signal is back to being bad again. So I can either remain stock or switch back to Verizon or go with 3vo. I came to sprint just for this phone so I can root and play. I don't know what to do. I have 18 days left until my 30 is up...
Sent from my Nexus S 4G using Tapatalk
I rooted a couple days ago, haven't noticed much of a difference in signal strength practically... BUT my time without signal went from 1% to about 8% . Obviously battery life suffered somewhat.
Currently I'm on EvDO rev. A.
Will continue to post updates.
So I have switched to the hybrid 00001 prl for now and I get decent signal, eve get some at work. I figure if I'm going to switch tithe 3vo in a week I won't go over the 300mb roam limit. Its a shame too I like this phone, I just want something j can play with.

Phone drops signal every few secs, 3g remains...

Hi guys,
My nexus 4 drops my signal every 10-15 seconds, the signal coverage 80 percent of the time remains showing full signal/3G etc but data drops constantly.
I have tried stock and custom rooms with little effect, my network provider blames the phone. I haven't had a chance to test it on another network but before I do was hoping to see if others may have experienced the same!
Below are some screenshots from a signal monitor.

What was your old ROM? I may try it as I am clutching at straws here. Radio, music, youtube... anything that requires data streaming just buffers every 10 seconds for 1-5 seconds. It is frustrating to say the least!
Stock Kernel didn't let my phone boot, Franco Kernel seemed to make it worse! I don't get what the issue is

Im using Paranoid Android with an older radio for LTE but the newest update seems to be when my signal went funny somewhat. I am on the .33 radio with matrix kernel right now but my phone signal seems to be lower than it was in many areas after the July 22nd update. Could be coincidental.

[Q] Maximum Signal Bar is 4

Hi,
I would like to ask if it is normal to have a maximum of 4 signal bars in S4? I'm already using the optimized modem in my country but still receiving 4 signal bars max in return.
I don't think it is a coverage problem though since I already tried my SIM on my old S2 and it is showing 5 signal bars without any problem.
As of now, the maximum Signal Strength I can get is -77dBm 18a asu (2G).
Any help on this? Should I consider on deviating my 'optimized' country modem and flash a different one?
Thanks!

4 bars is the maximum SHOWN on the Galaxy S4 -77dBm is high!!! I currently have three bars at -98dBm! Basically the Scale is 0 to 4 bars.
I would leave the modem as it is especially as it is supposedly optimized for your country. Don't fix something that isn't broken!
I hope this helps,
4 bars is maximum? Why is that?

how did you optimize the modem ? i seem to having a lot of issues with "Not Registered on Network" and I must restart phone in order to make calls etc . Stock 4.3 android
No I mean I'm already using the optimized modem for my country.
My only worry is I'm still getting 4 bars signal max instead of 5.

I don't know what your on about, almost every phone I've ever had has only ever had the display show a maximum of 4 bars, except a small % that had 5 rare I'm pretty sure.
In my radio world S 5 is actually more correct.
If you want more bars go get network signal info from the store.

You are using Wanamlite Rom, right? There's an option in the Wanam Xposed app that controls the number of bars shown. The default in wanamlite is 5 (up to 6), but the signal isn't adjusted to that number of bars unless you tick the 'Adjust signal levels' option.
Thanks problem solved ..it was due to Wanam ...

4.2 vs 4.3 data speeds

I remember hearing that when people upgraded to 4.3, their data speeds started to slow down. Is there anything showing which radios are faster than others?
Try each individually and check the signal strength and speedtest to find out your self.

Well holy hell, I was using Carbon 4.3.1 with the stock radio and with Franco 193 and only getting around 1mb download speed for some reason.
IN THE SAME LOCATION
I switched to Carbon 1.8 which is 4.2.2, with Franco 165, and a hybrid kernel (with LTE enabler, but switched APN from LTE to GSM) and I was getting 15mb down, for some reason same speed with LTE only and GSM only.
Not sure why that is, I'm in Kansas City, which does have LTE for Tmo, but whatever, I think this proves my point.
Well if you're speed was low on LTE then you just didn't get good LTE signal, that's the problem, you just had to disable LTE. When you flash a rom, it doesn't flash a baseband so you are using the same baseband, just without LTE enabled. Doesn't have anything to do with OS versions (you would think if this was an issue it would have been an uproar over the internet.)

There were a lot of Nexus 4 owners complaining of slower data speeds after the OTA to 4.3, just google "Nexus 4 data speeds 4.3".
Also when I was on 4.3 it was all stock, there isn't an LTE fix for 4.3 I don't think. So yea, I was updated with the newest baseband (radio) and it was just really slow for the past week. In my specific case, the baseband/OS version does have something to do with it.
If I can go from 4.3 at 1mb/sec to 4.2.2 at 15mb/sec in the matter of a few minutes by flashing a few things, then I'd say there was a problem.
I had the opposite experience. Going from 4.2.2 to 4.3, my data speeds went from never topping 1 Mbps to between 3 - 7 Mbps on the stock radio. I also still get the better speeds with any of the hybrid radios I tried on 4.3.

There are hybrid radios or LTE enablers for 4.3? Where? I've only seen the thread for 4.2.
