Cannot update PRL or Profile Error codes

So for a while now I have not been able to update my PRL or Profile. It hasn't bothered me because for the most part the phone has worked fine until recently. A friend texted me and said he was going to call me. He text back a few minutes later and ask why I didnt answer. Phone was next to me the whole time and it didnt ring or so any kind of notification that he had tried to call. Took him 3 calls before my phone rang and he got through.
I have applied for a few jobs within the past few weeks and have heard nothing from anyone which I am surprised because I was referred to one company by and friend who put in a good word for me and said that his supervisors were really impressed with my resume. So now I feel like this issue could possibly be costing me job opportunities and I want to get it figured out.
The errors are 6602 and 407. I've tried to do it over 4G and put my phone just in CDMA mode for 3G only and get the 407 code for 3G and the 6602 over 4G.
I am running Stock rooted/odexed MK2 and I just did a clean flash of the rom again clearing data/cache and dalvik seeing if that would help which it didn't. I have reflashed the modem seperately also with no help.
I have seen many threads of others having this issue but no answers on a fix. Has anyone experienced this and actually done something that has resolved the issue?

If you feel it may be costing you a job, why not flash a nand of a stock rom, assuming you have one

I did, I flashed back to MF9 using this http://www.rwilco12.com/Files/Devic...H-L720)/Stock ROMs/MF9/Full Restore/Unrooted/
Which should be a stock factory restore, still would not update profile or prl. From there I updated to NG2 with Samsung Kies and I am still not able to update either.

What kernel do you use?
(I fixed this issue I my phone, but SERIOUSLY, what seemed to fix it MADE NO SENSE, so I'm not going to to relate it again, you can look up my posts if you want, but I wouldn't waste your time. I'm more interested in what kernel you are using... if it isn't KT-SGS4, then it doesn't matter.)
Other than that, have you tried the ##72786# dialer code, which is supposed to reset that stuff (didn't fix it for me personally)? You may have to reactivate your phone though (I did), which isn't that much of an issue...

For kernel version it shows 3.4.0-2162929 which I'm guessing is the stock NG2. I haven't flashed anything else since updating through Kies to NG2.
I've done the 72786 dial code a handful of times and it still didn't help. The only thing that solved was a issue I had after I first updatd to NG2 I had no working 4G. Phone would only connect to 3G and that was when it was in CDMA only mode. Aside from that it hasn't helped with the PRL/Profile update issue I'm having.

Yeah, that does sound like a stock kernel to me. Have you tried updating it through the Sprint Zone app? In Settings, More Networks, Mobile Networks, Network Mode, if it is not set to Automatic, you can try setting it to that and see if it lets you update after reboot, I have heard that can help but did not fix it for me (I have it set to LTE/CDMA). Have you seen this thread: Galaxy S4/Note 3/Mega - Update Profile/PRL/HFA Fix for Sprint/Boost/Virgin Mobile/etc? It is complex (don't IGNORE steps 5, 6, 7 and 8, which most people in the thread seem to...). I have not personally used this method, I was planning to before my issue resolved itself, but I didn't have a donor GS4 either (damn it, I JUST remembered that I DO, I f*ed up the USB port on my first one and completely forgot about that! BLOW MY MIND! But anyways...).

Thanks for the link I'll check it later. My account is actually a SERO account but I did have working updates when I first got the phone. The phone was also new and activated on the account as soon as I got it.

Yeah, I honestly don't really understand what that thread means when it talks about flashing to legacy accounts. I believe I have a SERO account (I don't know, my wife pays the bill... :silly: ) and the updates worked fine until I think messing with the APNs to try to fix my inability to send MMS messages messed things up. I never flashed any legacy accounts or anything.
So... at this point, even though IT MAKES NO SENSE, I will tell you what SEEMED to fix the issue for me. I STRESS, this MAKES NO SENSE TO ME, but after months of being unable to update my PRL/PROFILE, after doing the following, I was suddenly able to update them. It is likely an EXTREME coincidence, but for the hell of it I will now tell you.
Using the Pro version of Solid Explorer, I copied the Carrier folder from the root of my phone to my external SD card. THAT IS IT. YES... THAT IS IT. NOTHING MORE. I did NOT copy it back, I did not change anything. HOW this could possibly have cured the problem would seem to make very little sense, I can only conjecture that Solid Explorer, in the act of copying the folder to my external SD card, somehow 'refreshed' something in the carrier folder in the root of my phone... and I am grasping at straws here. I think you can probably understand WHY I did not want to reveal that this is what SEEMED to cure my issue, because it is so unlikely, and more likely an extreme coincidence and something else happened that I am not aware of, but that is the only thing I know of that I did related between when it was not working to when it was. So now you know at least (and as I have told a few others, there is no point in not trying, other than the crushing disappointment of it almost certainly not working)...
I should add as well however, now that it occurs to me, that I use the KT-SGS4 KitKat 4.4 TouchWiz kernel, and had for a long time suffered from a loss of mobile connection and GPS. requiring a reboot to get them back (within a similar time period to my PRL/PROFILE issues). I seem to have fixed the mobile connection/GPS loss by choosing the 'correct' governor to use with that kernel for my ROM, and it is not IMPOSSIBLE that THIS occurred at the time I was able to update my PRL/PROFILE, but I do not remember exactly, and I'm PRETTY CERTAIN I still had the issue with the mobile connection/GPS loss after updating my PRL/PROFILE, so I think that likely rules out KT-SGS4 as a culprit in this issue. (But then, I was forgetting that we already established that you were on a stock kernel...)

Yeah that copying the carrier folder don't seem like it would do anything but maybe I'll give it a try. Whats the best way to root right now? I just want to make sure it will let me unroot the phone if it dont work and no trip knox incase I have to bring this in.

Do you know what bootloader you are on? You said you were on Sys MK2, then went back to MF9 and now are on NG2. When you went to NG2, unless you took very specific steps to keep the MF9 bootloader, you would be on the NG2 bootloader now, which includes Knox, and you can no longer go back beyond NAE I think. If you don't know what bootloader you have, get DeviceInfo https://play.google.com/store/apps/details?id=com.jphilli85.deviceinfo from the Play Store and under the Software heading, see what it shows for the last 3 digits for Bootloader. This makes a difference on the best root method.

I'm not an EXPERT on this subject, but if you are on NG2 stock unrooted right now, I believe you can use: CF-Auto-Root to root it. Or, here is a stock rooted version of the NG2 ROM:
[ROM][NG2] Stock Rooted NG2 (which mentions that it has Knox removed).
As far as tripping stuff, I'm somewhat unsure about that to be honest. I have always used Triangle Away on my phone, but it has a warning now not to use it with a custom kernel (which I use). My counter is at 3, but I am out of warranty anyway.

I spent a few hours on chat with Sprint. They couldn't figure it out so I'm bringing it in tomorrow. Guessing I'll get a new phone. The people at the Sprint store seem rather limited in their knowledge, at least they were last time I was there.

I guess if there are no signs that it has been rooted, that's probably a good way to go. You apparently had a phone pre-Knox and now I think you will get one with a Knox system, but it doesn't matter in your case since went beyond the point of no return already with the bootloader... I don't know if you have the new Spark model (tri-band), I don't know if the still make the old plain one like I have anymore...

I got the phone I have now about a month after the GS4 came out so its non sparks. I stayed on MK2 for so long because I couldn't find a newer rom that looked to be stable and not have to jump through a bunch of hoops to install it. The Odin screen shows everything being zero and offical software so I should be good. I am going to sign out of all of my accounts before I bring it in being I have a lot of apps bought through the store that only work on rooted phones. I hope I can get a tri band to replace it. My friend has a triband GS4 and it gets much better data speeds than mine.

Yeah, I mentioned elsewhere here before that I actually didn't know of the existence of the "Sparks" version of the G4. I screwed up the USB port on my G4 before upgrade time, so I had to buy another G4 on Amazon. Upgrade time has come up, so I was just looking and saw my phone listed as "Non-Sprint Sparks", which I thought meant that they called it the "Sparks" model because I hadn't bought it from Sprint... took me a while to figure out what that actually meant... :laugh:

Sprint online nor the store could fix it so I got a new one.

No rooting but error 407
As titled, I've not rooted the phone. I'm getting error code 407 on attempts to update PRL and Update profile. Download updates manually does nothing. Note I'm on a Samsung Note 4, Sprint. Had updated to Marshmallow 6.0.1 late March but then above actions persist since then. I'm using Wi-Fi only, Sprint service disconnected as I couldn't pay bill when I lost job during a disabling illness.

I haven't been able to update prl profile or firmware for over 8 months. I am not rooted never have been I have called customer service over and over replaced SIM card did the ## stuff nothing has helped. The phone works although service isn't as good as it could be and says there is a prl update available but I always get connection error 6 on all 3. I also have serious battery draining issues as far as my data I do get a strong 4g lte connection just service is low and sometimes drops when I am close to a sprint tower every other phone gets full bars really on any network especially sprint. I hope someone can help I like my sph-720 other that that and honestly I can't afford to keep up with the Joneses. Hopefully this is enough info please help

Have you done a factory reset via recovery? Or you might want to flash latest full stock

microphone acting up

I recently updated my xt575 with the September security patch. Since then my microphone doesn't work only when making a phone call on speakerphone. Normal phone calls, audio and video recording, and voice commands all work just fine. I have tried booting into safe mode with no success, and then did a full factory reset and held off on downloading anything before trying again, still with no success. Is anyone else having this issue? Does anyone know of a fix or workaround for this before I try contacting Motorola? Thanks.
P.s. I am on stock ROM on Att network. I use Android pay a lot so would like to avoid rooting.

Same problem
Hello. I'm trying to solve my Moto's mic for over a week now.
I was trying many ROMs, but ended up using TruePureXMM ROM along with franken kernel.
It was all working fine, except some overall phone lag and constantly trying out other kernel auditor settings...
...untill about 2 weeks ago. Phone's microUSB port got damaged, and I had to return my phone to repair service.
After I received it back, I wanted to try out some Nougat ROMs, and tried couple of them, but found out that the mic isn't working properly there.
Decided to return back to stock, using this forums tutorials, done it without any single errors or problems in the process, I did many devices roms changes before.
It didn't help at all. The receiver don't hear me at all, the only sound they can hear is when I blow into the mic's direction.
*Note that when I change to speaker mode, the receiver hear me with some breaks in between, but it's the only way to call from now on...
I'm confused now, completely no idea if it is really the OS problem, or if it's just something with the microphone itself.
Looking forward for any tips, thanks for help.

Nexus 6p constantly dropping signals

Hi,
I have seen some posts here with lost cell connectivity. However my issue is slightly different and started to appear few weeks back. I was rooted running stock 7.1.1 OS with Franco kernel. My phone started to loose signal all the time. You can just look at the signal bar and see the signal strength going all the way from 100% to 0% in every few seconds. I have tried different radio versions, new ROMs, restoring my Nandroid backup etc. Nothing seems to work. Changing to 3g shows the same issue and I have no signal on 2g only mode. I am in AT&T.
Also wanted to add that I can make out going calls from my phone. The issue is when its idle. I don't get any incoming calls due to this issue.
Any help will be highly appreciated. Currently using my office iPhone and feels terrible.

I'd run up to AT&T and ask for a new SIM. It's free and you rule out something on their end, and the SIM too when they provision it. Is your phone carrier (SIM) locked to AT&T? If so, I'd see about getting it unlocked so you can test other carriers. If already carrier unlocked have you tried borrowing a friends SIM on another network? If signal continues to drop it could be a hardware issue.

You sound proficient enough with flashing ROMS, radios, restoring Nandroids to know this already.... you are probably just postponing the inevitable: Back up and pull off all your data, format the partitions, and flash the latest full factory image from your PC using flash-all.bat. You will have your answer very quickly- in fact you will know even before you begin to set up your phone. If you are still under warranty this will be step number one with Google or Huawei.

My Nandroid backup was actually a vanilla 7.0 image. I will give this a try with the flash-all.bat and update here

Any update?

sporadically losing data connection - reboot fixes temporarily - any ideas?

This has been happening for a couple months. Seems like a couple times a day I lose my data connection, and the only fix is to reboot. After that it's fine for a while, until it drops again...
Running rooted 6.0.1, radio version 3.61. Anything I can check? Or should I just flash a new image?

I have this issue, flashing different radios did nothing for me. The hardware is just going bad I think

Been having the same issue for a couple months now, going to my carrier for a new SIM and resetting APN did nothing. Thought it was my ROM at first and ended up flashing a few different ones along with kernels, it was never fixed. Data drops and comes back about 10 minutes later, every half hour or so. Seems to not effect calling or messaging, only data. Is this a confirmed hardware issue?

My wife and I both had our 6P's doing this as well. Seems like the device will get in a connection loop or something. the WiFi drops, then my 4g data signal, then both are out, then WiFi turns on, Data turns on, then repeats the process. I usually reboot, or toggle airplane mode off and on to stop it. Its periodic, but it doesn't last long on my end. I'm on T-Mobile BTW

UPDATE - REFER YOU TO THIS LINK. Looks like radio files from Android O Beta DP4 are confirmed to fix the T-Mobile Cell Signal Bug

My radio didn't drop once on the way to work today, hell, it's still going right now. I actually think it's been fixed

is it ok to apply the updated radio without upgrading android (staying on 6.0.1)? i heard there have been some issues with 7.x on the Nexus?

I do not know its comptibility with 6.0.1 - you could just make a backup and give it a try.
conversely I must say - Nougat on good ROMs is stable and gets good battery life. What are you concerns with just joining the party here on Nougat?

-----------------------------------------------
I'm running rooted stock android. Haven't made the move to any custom ROMs yet. I recall when Nougat first landed people were reporting some issues with it on the 6P (battery life? instability?).
That being said I'm open to loading a Nougat ROM if it's gonna be stable. Is there any consensus on top ROM for the 6P (something close to stock android experience)?

Close to stock with aroma installable features, check superxe rom, you can choose between nougat or Android O.

My LG-H918 (T-Mobile variant) updated, and is stuck with "no service/radio off"

Wow, seeing that this is quite the phenomena. It seems everyone has this in some form since that December update
I'll skip the small talk because this issue is widespread enough... here's what HASN'T worked
- *#*#4636#*#* (Trying to use "Phone information" leads me immediately to "this application does not work on this device")
- Taking out SIM and battery for 30min
- Swapping SIM
- Factory Reset
- Praying that anyone at T-Mobile has attained a level higher than "Totally clueless"
- Praying that anyone at LG would provide a working solution
- Dialing ##UPDATE# (Afaik, this only works on Sprint)
- Five hours of googling
As it stands, I'm stuck with a phone that's awesome at doing everything but being a phone. Apparently I can flash a radio file... but I haven't the slightest idea how to do any of that.
Any idea how to fix this?
*UPDATE* looking into the dirtysanta method of flashing the modem.img, it appears that's not even an option for the T-Mobile variant.
Sounds like LG's solution is to have you send it in... I've already seen other users go through that and end up having their phone hostage for a $21 diagnostic or a $378 proposed HARDWARE fix for a SOFTWARE problem _they_ caused.
While I personally have had good experiences with LG in the past, looking into this really kicked the hornet's nest on others who've had this issue. Many coming from the V10 who were told a V20 would save them from this.
Sounds like it's time to sick the social media beast on a company to make them stop being shady.

I have a tmobile v20 and I have not had any issues with service and I have not seen much on the forums. What issue are you having exactly? Were you rooted? Any errors besides no service?

Basically that's it. Phone worked perfectly, did an OTA update, and now it's like my cellular radio just doesn't work at all. Which means I now have a WiFi only media player that can't make calls, SMS, MMS or utilize cellular data.
Goes straight to "no service". I can go under Network settings and it displays that my phone's radio is off. T-Mobile rep confirmed that my SIM didn't shoot craps, and that none of theirs work in this phone either. They actually showed that the phone was even detecting my SIM by showing me that it's picking up my phone number.
Surprised you aren't hearing about this, I'm seeing this reported all over the place. This is just a couple of links. Been going at this all since the OTA hit me at 6PM yesterday.

An XDA user sent his in, and ended up having to either pay a $21 diagnostic fee, or pay $400 for them to shove a bunch of aftermarket parts in his phone (which is insane given that the only thing between the phone features working and not working was an OTA).

Have you tried reflashing a kdz? It is possible that something happened during the update. Make sure you flash a kdz with the same anti rollback number (most likely 1 if it took the recent ota). I believe the patched LGUP can flash just the modem partition.

Yeah. I heard about this. For the other xda user, he had purchased a refurbished device from a third party seller of some sort. Some where along the way the internal parts (motherboard) were replaced with cheap knock offs. LG flagged the phone for having non-LG parts inside. The upgraded firmware didn't play nice with the hardware, since it wasnt built to LG's specifications. Anyways not entirely LG's fault on that. A kdz could help but I doubt it will do anything. For people who have lost radio functions entirely to just a simple ota, most of them have had to get hardware replaced to fix. All around bummer. Hopefully lgup can bring it to life.

I'm having a similar issue and can say that for us with ARB=1 (i.e those with the Security Patch past 01/01/18) aren't going to find salvation this way
It's coincidental this thread popped up, because I'm trying to diagnose a similar nature as well. I've been swapping out parts and testing to see what's going on as part of my phone repair. After swapping between different plastic bumpers (this is the antenna bumpers). I can say this is not a hardware issue for us DIY'ers. I've taken the picture in the Settings > About Phone > Network to show that my antenna signal is just as normal without a SIM inserted. (Picture 1). I believe this is not an IMEI issue because it comes up clean for both ESN and Tmobile's side. If it was a blacklisted phone, then I shouldn't be able to connect to Wifi Calling. However, multiple instances: I've gotten a Notification from Call Services yet still able to call/sms test but only with Wifi Calling enabled; which reinforces the observation that this isn't hardware-related. (Picture 2).
LTE Discovery confirms a working radio, as the EARFCN information populates with connecting cell tower activity that's typical of SIM activity; with the sole exception of my Data/Voice Network Types coming up UNKNOWN (Picture 3). MCC+MNC Information proves our phones are talking to Tmobile, at the least, which further shows this being less of a hardware issue. I've KDZ'd my phone with LGUP as far back as 10P to no success.
If there is a problem relating to OTAs; someone else has to investigate before the ARB = 1(Anti-RollBack) to discover more information. Those of us on 10P aren't allowed to test out previous modems due to our bootloaders; which incidentally is all of us with this No Service problems. Ack!

10p Warnings based on what we know:
WARNING #1 You must flash the 10p modem and bootloader for this to work. If you don't you will soft brick.
WARNING #2 Once you go to 10p modem and bootloader you can't go back to previous versions. If you try you will HARD brick your device.
WARNING #3 10P rom only works with 10p modem and 10p bootloader. Any other combo SOFT bricks.
WARNING #4 TWRP backups of previous versions will not restore correctly once you are on 10p. When you restore a previous version (10k and before) you will soft brick. You can unbrick by just installing the 10p ROM, modem, and bootloader over the top of your restore *****Restores and Backups of 10p roms work just fine.
BOTTOM LINE: Going to 10p is a TOTAL commitment and there probably will never be a way to go back. That said, I'm on 10p and so far it works great.

[FIRMWARE] [H918] [10p] [10k] [10j] [10i] [10d] TWRP Flashable Bootloader and Modem

I'm having problems with a VS995. Bought it new on ebay, received it today 10/27/2018. I did get signal, then upgraded via phone software update, but it failed, and failed, and failed. so i used the verizon software via pc. Successfully upgraded to 7. then NO SIGNAL. so i updated via phone, but the download kept disconnecting. so i downloaded the 8 bin, upgraded via LGUP, success. Still NO SIGNAL. =( . Returning the phone now. buying a used one, might be better.

Was this problem solved? Because I have the same thing, radio off & really slow charge (phone has to be off in order to charge, when on the battery drains faster than it charges). I've flashed 10p with lgup & it's the same thing, right now I'm rooted with TWRP recovery, Magisk & the H91810u rom. I've done factory reset, flashed modem zip file, installed a network app that trys to manually start the radio (radio on) but it fails & stays "radio off". Any suggestions would be greatly appreciated, I'm almost ready to give up on this thing.

If you read you'd know it wasn't, as stated by earlier posters the only fix is to send to LG for repair, you probably got one of those knock off phones

How could that be this phone was bought from T-Mobile, I would doubt that they would pull a stunt like that. And wouldn't it have had the same problem before when I rooted the first time? Or am I missing something here?

Return it to, Tmobile, or send it LG to be repaired, scrap it and buy a new phone.
