Wanted to see if anyone else has been experiencing the same thing.
I've got a T-Mobile variant S8+ which I switched over to Verizon, currently rooted via SamPWND and running unlocked firmware for 2 months or so now. Everything has been perfect up until 2-3 days ago when I would look down and the phone would be on a factory reset styled crash screen. It would run a series of tests and say there was a kernal error, most of the time dealing with the modem, which I would then have to restart the phone without issues and carry on.
Is there any way to test or check what the issue is all of a sudden, or a direction I should go to update to a newer firmware while still retaining root. On baseband G955U1UEU1AQG2, kernal 4.4.16 (dated Mar 26), Build NRD90M.G955U1UEU1AQG2. SW Service provider SAOMC_SM-G955U_OYN_VZW_0177, VZW/VZW/TMB.

As some of you may know, my O3D was sent to LG service repairers Evertec to fix a broken power button. I asked them to fix just the power button under warranty - my phone was on froyo (i was on the leaked GB but because of ghost calls and data dropouts i reverted to froyo) and i just got my phone back today with a note saying the power button was fixed and they flashed my phone to "the latest firmware"
Lo and behold I booted to a fresh install of an official Optus GB rom - baseband 20b but perfect reception. no dropouts or ghost calls. i think it may be rom related.... i do have some bloatware but at least i have no reception/data issues
im not sure if this rom is available ota or for download but the service guys seem happy to flash it on repaired phones!
yes,20b is online,but still not rootable
I had 20b installed before but it wasnt the Australian Optus rom... Whatever rom that was, it always gave me grief....now no problems at all. in fact optus even sent me a message with settings in it - i havent activated it as yet as my reception is currently working perfectly fine without it.
Guys, please be aware that LG version numbers ARE NOT CONSISTENT, at least not the way we think of it. European v20b is not the same as India v20b.
In fact, each region has it´s own version branch, so you can perfectly have, for example, Romenia v21a with the same baseband of Croatia v20b.
So, don´t be fooled by equal version numbers: you can only compare version numbers when comparing software for the same region. If you cross regions when comparing, you will get it all wrong.

I installed the same rom as you, 20B Optus, took my external SD out and formatted the phone to factory, for one day the phone worked well then the problems started as before 3G getting stuck can't go to airplane mode I had to restart the phone, after it happened over 4 times I installed froyo. Same thing exactly happened to my friends O3D, Evertec changed the board on my phone when I took the phone for service for the random rebooting problem, now it is very hard to sell the phone if I tell the potential buyers the phone was serviced. So I am stuck with it.
I use it like Thiaz as a media device now and I use My Iphone 4 as my main phone.
what is the use of a phone if it can't be used as a phone?

I noticed you're posting from a 925... Mines a 920.... I never had a random reboot and I've installed the Acura and Thiaz roms - used stock roms, OC'd and the only GB rom working properly is this one....
I'll keep my fingers crossed that it stays this way....
Admittedly I never had any issues on Froyo - If this rom does play up I'll downgrade asap. I won't miss the GB features all that much

You noted correctly, but my one is an Optus 920, I was so desperate so I am using Froyo Baseband and the CM GB for the 925, this was my last resort, the phone works very quick with no lag, and I charge once a day, hdmi does not work, and I can't view photos in 3D, but this phone is good for playing games, that is all I use it for.
I have intalled the update to my optus lg optimus 3d thought lg update tool, i have had 2 missed calls i did not receve that i know of and really bad battery life. i might have to do a factory reset if this does not fix i will not be happy.......back to lg

Good Luck mate, they will tell you that you are the only one in the world that is having this problem, all the staff at the LG service center (evertech) are using GB without any issues what so ever.
you will be told (you are special)
Ok... Here's the weird thing - I know people seem to be having problems using this rom... I am not one of them (so far) I had issues on every other GB rom but this one. Maybe it's related to signal strength, carrier specific settings or something else. I really can't explain my lack of issues. I do set my phone to 3G only - as I don't want it jumping from 2G to 3G but that's it as far as any phone changes.
*I am using the Optus GB rom on Virgin Australia (they piggyback on Optus - slightly different settings but same network).

Please keep us posted, I am on Vodafone and the signal is shocking where I live (inner west) Vodafone will be updating the network next month.
but I do not have any issues with my iphone at all, and when I go to my other house (castle hill) where the signal is perfect -50 db I still get the baseband crashing.
I used the phone for 2 weeks back in November when they released the Europe Open before I stated getting complaints that I am not answering Phone calls and I missed out on couple Jobs worth over a grand!!!
Quick update.... 1 week later and still no issues - strange but true! No missed calls (that I'm aware of and no loss of data... Perfect reception... For virgin mobile customers on Optus GB rom - no issues.
GPS lock perfect - regaining signal after airplane mode perfect, over 400MB in data in a week and no loss of reception, perfect... This is the only rom that works for me on GB without ghost calls, internal reorganizing crap or loss of reception/data
I can't root and have some bloatware but I can live with that...
Will update if things go bad but for now I'm VERY happy!
Thank you so much for getting back to us, I will be trying the 20A Australia again, this time around, I will take the SD card out, will fully format the phone and only install couple important apps that I need, I am doubtful but at this stage I am willing to try anything. will try the 20A for 3 days and will report back.
Edit:
Day one: No Freezing and no missed calls at all.
Hi everyone. Just to start out, I am completely new to the Android world – I’ve tried to read up on these forums and whatnot but I am definitely a noob. I am coming from Apple, and long story short, I’m tired of iPhones and got myself a Galaxy S3 via Swappa in order to keep my unlimited data plan. It was previously rooted, but I requested that it be restored to stock.
I have been unable to get to a Verizon corporate store to get a sim card and activate the phone, so I’ve been using it on wifi around the house. I am having signal issues with the wif – it works everywhere except in my room. The signal shows as weak and keeps dropping every few minutes. My other devices have a strong signal. I have downloaded various wifi analyzer apps from the Play store, and they all show the wifi signal as really weak.
I searched and found numerous threads that this is an issue with some of the phones. I tried messing with settings (factory reset the phone, the router, did the *#0011# and turned wifi power saving off, changed the "keep wifi on during sleep" from always to never, etc) and nothing fixes it.
I would like to know what you guys recommend. Should I go ahead get a sim, activate the phone, update to Jelly Bean and see if that fixes the issue? I am unable to get the update since I do not have service. I tried to update via Kies, but it says current firmware pda:lg1 phone: lg1 csc: lg1 (vzw) not supported.
Or should I tell Verizon about the problem and see if they will go ahead and replace the phone? I’m not sure how that works since I am not the original owner. I’ve read that they honor the warranty based on the purchase date which is tied to the IMEI number, and not the owner’s name. Not sure how true that is… Also on the box, it says Verizon 4G LTE Certified. Not sure if that means my phone is already a certified replacement or if all the boxes say that. I haven’t been able to find that out.
I’ve read the thread about resetting the phone to return to Verizon. The flash counter screen reads Odin mode, product name: SCH-I535, Custom Binary Download: No, Current Binary: Samsung Official, System Status: Official, Qualcomm Secureboot: Enable. The android version is 4.0.4 and the baseband is I535VRLG1. Does it matter what the kernel, build number and hardware version are? I’m not sure what they should be.
I just want to be prepared when I walk into the Verizon store (which is unfortunately over an hour away), so I’m hoping I can get some opinions and maybe save myself multiple trips. I’m not sure if Verizon will work with me or not, but I figured you guys are the experts and can help me out. Thank you!
It looks like the guy who sold you the phone did in fact fully return you to stock. But it is fully stock based on the oldest stock firmware (I535VRLG1). My advice to you would be to activate the phone, and grab the OTA updates all the way up until the current version (I535VRBLK3).
I used to have all kinds of WiFi connectivity issues with this phone, until I replaced my router. Now it works perfectly. There was no real explanation as to why that was, but this phone does seem to have WiFi connectivity issues, especially with older Routers.
Try updating your software first, and see if the problem resolves with the new firmware. I believe Verizon does base the warranty off of the phone activation date, at least they did years ago in the past, but that may have changed.
Thank you, I appreciate the reply. I read that there was an OTA update issued around October to fix some of the wifi issues, but I wasn't sure if I had it. Once I activate the phone with the sim, do you think there will be any issues receiving the updates? I know nothing about rooting and have been trying to read more about it, but I'm concerned I'll end up causing more problems with the phone before I even get to use it.
The router I have is a free one Verizon gives to use with their dsl service - a Westell Model 327w. It is pretty old, although I think the firmware is up to date. The phone works fine when it is closer to the router and everywhere else in my house, except my room which is upstairs and at the other end of the house. I just figured since my other devices work fine, the S3 should too.
Thanks again.
If you are fully stock, with the stock recovery (which it sounds like you probably are), you should have no problem downloading and installing the OTAs. I believe you will have to take a few them before you get up to the current version.
I can confirm that the stock Verizon GSIII has a few upgrades before you get to 4.1.1 (the latest version)
Thanks guys.
I just remembered that I have a newer router that Verizon sent me, but I never bothered with it because the current one was working. I'll try and set that up and see if the signal improves.
I am hoping to get to the Verizon store soon, but unfortunately things keep happening that prevent me from making the trip. Can't wait to get this phone working though. Just the little bit I've played with it makes it difficult for me to go back to my iPhone.
This is how a noob post should read. Nice job, OP -- very informative and you did some homework.
Other noobs take notice -- this is how you do it. Notice how much help he got?

If its any consolation, I had wi-fi issues even with a newer Verizon router all the way up to the latest version of the the modem and rpm file (vblk3). With the last and latest (vblk3) update, those problems disappeared. So as stated, I would update the software to the latest and hopefully you should be good. Just to add, my wife had the same problems (same phone) as well so this validates for me that it was a software issue.
Hey everyone,
I've never really been into the whole flashing deal and I'm also pretty new to the xda-forums so pls don't hurt! :angel:
Anyway, so live in Germany and imported myself an S6 Dual Sim Version via Amazon, so that I could have Internet both there and at home in Ausria at all times. It had a Russian Baseband and CSC but it worked and filthy casual that I am I really didn't mind until now. It's a really weird issue, so sorry that the post turned out pretty long. I haven't found any similar common 6.0.1 Bugs, however I'm not even completely sure if it really is a problem of the updated OS anymore...
So here's the deal.
In Germany I got the prompt to update to Marshmellow 6.0.1 via OTA. Having heard mostly good things about it I downloaded it without really bothering too much about informing myself about any known issues with 6.0.x . After downloading it in Germany my Signal and Mobile Internet worked fine, however I did experience some battery drain in the following days and decided to initialise my phone via Samsung Smart Switch, as I had done with 5.1.1 when I first got the phone because it's cpu never went into sleep mode. Worked out fine then.
Well ever since I did the same thing with my S6 with 6.0.1 the whole dilemma started. Regularly, my phone will show 4G Signal Reception and even full bars, but I am not able to load a webpage or even be called by phone. Wifi works fine, when I have these outages. When I activate flymode and deactivate it again, my reception works again for a couple of minutes, however, the issue will return after 5-10 minutes. Usually even faster when I'm in a moving car or train.
When I switch SIM Cards I can be called on both, but I can't seem to connect to my mobile internet on the Austrian card (can't check on the mobile connection from the german card as roaming is locked by the provider). I went to my austrian network provider and had my sim card replaced, no change. I flashed DBT G920FXXU3DPCA Android 6.0.1 via Samsung Updates hoping that the right baseband would fix it - Nope.
Any of you guys have any other ideas? My last resort is flashing back to 5.1.1 stock. Trying to replace it through Amazon will probably be hard, because the KNOX Counter is tripped. It already was before I flashed 6.0.1, but that doesn't really matter to Amazon I guess. Also the bug is way to specific to replicate anyway, so I'd probably receive the same device back and I don't really know how I could prove via screenshot, etc...
If there's anything I can upload that would help, pls tell. Hoping somebody here might have an idea!
Having similar problems but also with wifi. Any advise appreciated

I have the same problem with cellular reception with my S6 duos G920F. My problem is only with sim slot 2 though. It seems to show full bars but when people call me they are getting me as unreachable.
A few months back I updated my phone (was on stock) ever since then I am having issues with the reception in my phone (signal dropping out, going down to 3G from LTE and so on)
I unlocked the bootloader and installed TWRP, tried multiple ROMs, even tried flashing different firmwares but nothing seemd to help, I also sent my phone to a lab (when I still had warranty), they replaced the antenna but there wasn't any difference, has anyone experienced this issue before and managed to fix it?
I am currently using the latest Cyanogenmod nightly version.
I recently picked my note pro 12.2 back up after some time sitting unused. I finally got around to getting the flickering screen fixed and want to get back into using the tablet more often. The issue I'm having now is updating to a more recent firmware. I'm unable to even check if I have the most recent firmware because I don't have a Verizon data plan or SIM anymore (long time coming) and it doesn't seem to want to update without that connection. Does anyone have a way to go about updating the tablet manually?
Also, is there anyway that I can flash the Wifi firmware on to the tablet so it ignores the fact that I have the data connectivity and acts like a wifi model? I've rooted multiple phones in the past, and as long as I have a good set of instructions I can do quite a bit but I'm still looking for an answer to this question.
Thank you.
you can use samsung smartswitch for PC: http://www.samsung.com/us/support/owners/app/smart-switch
to get the latest firmware.
just note if you need root, the new versions of 5.1.1 are not yet rootable.
unfortunately this device has a locked bootloader so flashing a non Verizon firmware to get wifi only is not possible currently.
I have noticed if you have a sim card installed with no service (I have a Tmobile sim with no service currently) it drains the battery pretty bad as it keeps looking for service, connecting and then disconnecting.
I turned off mobile data in the settings which fixed that for me.
Thanks for the info. I'll take a look at updating it to the latest firmware. I don't need root, was going to do it if we could flash the wifi firmware.
