Data drops after Nougat - Nexus 6P Q&A, Help & Troubleshooting

After flashing new bootloader and radios and a Nougat rom I have been experiencing data drops.. Only a reboot will fix..
Tied a few roms with the same issue.
I have tried re flashing radio and still same results.
Any advice would be appreciated.

I've been having the same problem. My data will drop, but then reconnect. It happens quite often, which is super annoying. Not sure of any fix besides trying a different radio. I can't find any radio zips to flash without the bootloader.

Attached a log cat if anyone wants to take a looksy
Had to zip up logcat due to size limit

[Q] Did I f up after radio update...

Looking for some advise and guidance.
Flashed ROM Virtuous Fusion MT4G v1.0.2
Everything was working fine. With some of the great responses I've seen from the leaked radio 26.09.04.26, decided to test and take it for a spin.
No problems during the radio update. I'm now struggling to get any sort of data. It shows full bars of 3G and H (H majority of the time). However, just about anything that requires syncing or a data connection is failing.
Rolled back to radio 26.03.02.26 and have the same issue as the .26 radio. Also tried radio 26.08.04.30 with the same results. Tried fixing permission and still nothing. Wondering if I'm missing something or if I'm f-ed?
Have you tried another fresh flash or factory reset? Other than that don't know what else to tell you. I haven't messed with the radio due to reading some have encountered your same issue.

MIUI signal dropping

Hey guys,
before you guys roast me Ive asked the guys on the MIUI forums this question before but have been unable to get a sufficient answer other than "flash the newest radios" which I've done before.
My problem is when I'm at home(and only at home) I get an inconsistent signal. My phone will have an OK signal one moment, and then a minute later have no signal at all. This only happens in the apartment complex which I live in. Everywhere else my phone functions as it did before.
The problem apparently happens when I flash a new version of MIUI outside of my home. It happened this summer and never resolved for months, even after I switched to a sense ROM and flashed new radios. After a while the problem went away by itself and I switched back to MIUI no problems, and have been back on MIUI for a couple of months now.
Last week I flashed a new version of the ROM outside of home again and the signal problems returned. When my signal first went bad I contacted Sprint and they told me of a "single cell outage" however the other people with Sprint phones in my building get service. So I'm inclined to believe I've done something to my phone that causes this signal drop.
Can anyone please help me???
Well you did all the trouble shooting yourself if everything fails the only problem is possible is the phone itself. If you have insurance just take down to Sprint store have them check it out. Also try turning on roaming see if that helps. Best of luck.

Instead of upgrading your radios, have you tried downgrading?
It could be a coincidence that your problems happen when flashing away from home. It could also be that some file is made on first boot of the rom that somehow affects your connectivity. It doesn't seem likely, but I don't really know what else it could be. Try Reflashing the rom over itself without wiping data... of course do this while at home. If you're not wiping system in between flashes then try doing a full wipe - boot, system, data, cache, dalvik, SD-ext, .android_secure - and flashing MIUI while at home. I know that the problem persisted after flashing a Sense rom and updating radios, but it's worth a shot. If that doesn't work, try downgrading your radio and/or PRI/NV.

Thanks for the input guys. I don't have time to do a full wipe right now since I have finals in a few days, but as soon as they are done I'll do a full wipe and maybe convert back to a SENSE rom and update the radios etc. Then I'll flash MIUI again.

You only need a sense rom to update the prl; you can update the radio, PRI, and NV through a flashable zip in recovery.
So I never wiped my phone/updated my PRI etc. but miraculously I have regained signal at home. I received my bill from Sprint and a few hours later I regained service. Cheers to Sprint, the shadiest phone company not named Boost Mobile!

[Q] Problems with audio after flashing MGG

Hi!
I flashed a rom with MGG and got the same FC problems as everyone else. Flashed the stock MGG rom and cleared everything, factory reset etc. After that I didn't get any audio at all. Not ever during the samsung bootup animation.
I flashed another rom through cwm, same thing and no wifi. The wifi fix doesn't seems to work either.
Tried CM 10.2, there I'm getting wifi but instead no data trafic. Baseband says "unknown" even through I flash different modems. The wifi and data problems I can get around, its just that I can't flash older roms through odin until they unlock the new bootloader.
The audio problems in the other hand. Saw some guy having sound problems in the modem thread as well. Not to many have posted about this problem. Seems to be a pretty rare problem.
What could cause this, how to get around this?
Had to go to work with a non working phone so can't get any logs for you at the moment.
I'm concerned, please enlighten me!
Finally, flashed the latest CM 10.2. Got wifi and reception working!
Still no sound. What log would you like to see to find out what's wrong?

Issues with service on latest radio

So I have flashed multiple roms and I keep getting the same error. I will randomly lose my service after a boot and then a few minutes later the phone will say no sim and reboot itself. This has happened on two different roms (one AOSP based, one CM based.) Both time the roms were clean flashed perfectly. I have been forced to revert back to an earlier radio (from 3.61 to 2.15) just to keep my service. Has anyone else had this issue and is there any fix for it?
when did it start? because we have been on the 3.61 radio for about 2-3 updates already..
(cant remember exact date, would have to check my factory images to determine )

The latest Radio doesn't assure a benefit for everyone, and might not be suitable for your region. In my case it has boosted my reception, but that might not be the case for you. So, just roll back to a previous radio that offers better compatibility.

Bootloop and radio issues

Hey there,
Ever since flashing a new rom I've been experiencing a few issues. First, my phone refuses to boot to system, I've had to go through the bootloader to get it started every time.
Second it would appear that my radio is off as the phone won't connect to the network and thinks its in aeroplane mode. I haven't been able to get it working yet.
The Rom I flashed was the nougat update. , I've tried several others since as well as restoring through twrp. No dice, but I'm currently on lineage 15,1
I've yet to find a solution to either of these issues in a week of searching so I'm looking for any sort of guidance.
Thanks in advance

You should return to a pure stock configuration (including recovery) and start over, preferably using RDS Lite. It won't be easy as there are no giudes written explicitly for the G4P. You will have to derive the procedure by reviewing other threads.
A less comprehensive approach is detailed in the following thread but it may not solve your radio issue.

As for not booting to system that's likely due to a procedural error when twrp was first flashed. Check the TWRP threads for corrective action.
