I hope this hasn't been covered here before. I've searched all over xda and Google for a solution but no one seems to address my specific situation.
I used to have a Samsung Epic. I traded my friend for an evo. I swapped our SD cards since epic comes with 16gb. When I got the phone she hadn't made any modifications. Completely stock. My accelerometer and notification light worked fine at the start. Since then I've rooted and installed many custom roms. Before I traded her the epic I was trying to create more space on my SD card and wiped the whole thing. Bad idea. The Rom I was using kept force closing closing all my apps. I flashed a backup I had stored on ny computer and it was no problem.
I'm not sure when my accel and LED stopped working with my evo..these aren't features I use or pay attention to on a daily basis. I only really care about the accel and have been trying to fix it for quite a while now.
I've read in different threads to A) Unroot, wipe everything, and use an RUU to go completely back to stock. B) download and push the accel file over the old one under data/misc in the root of your SD and C) download the sensor debug app to see if it gets a reading. Ive tried them all. I'm back at stock, unrooted. I downloaded the file but when I wiped the SD card it deleted all of my root folders. When I used the RUU it created some of the original folders but not all of them and not the ones specified to replace the files. I tried to create them myself but it made no difference. When I opened the sensor debug app it did not get a reading..or...at least I don't think so, but I don't know exactly what is supposed to come up.
Everything I've read so far tells me this is a hardware issue...but if it was working when I first got it how could it be an issue with the hardware? I had to have erased some necessary file or source that's causing this problem. Right?
Does anyone have any thoughts or ideas? I guess since I'm not rooted anymore I could go to Sprint and have them replace it but I don't really feel right about doing that and honestly id rather just learn what I did wrong and how to fix it. I feel like there's got to be a way to format my SD card to the evo stock settings.
My only thoughts would be to either copy the contents of the original owners SD card, unless theepic has already gotten rid of her original evo files, or copy the contents of someone else's SD card who's evo still has these things working. Would that work?
Thanks in advance for reading this novel and for any input you might have. I've been lurking about in these forums for a few months now and there are some brilliant devs and posters around here.
Oh. One more thing. As I mentioned earlier, the accellorometer is what Im really worried about fixing. The notification light is of little importance but I feel confident that these two issues go hand in hand.
Thanks again for anything you may be able to contribute. This is a long long post for something noooot really that important or common.
Ok guys, been a long battle. I spent a combined four and a half hours on the phone with sprint yesterday morning. We did soft resets, hard resets. We checked ESN and other numbers I didn't know existed. We checked towers as well.
And after all this, I still have issues making calls. When I go to make a call at home, it automatically disconnects even though I have full bars and my data is working. I also cannot receive calls, as everyone texts me saying that it is going straight to voice mail. I only really go three places.(work, home, gf's place) The problem occurs at both my place and work. However, it doesn't seem to happen when I am on the road, and it only happens sometimes at my gf's.
I took the phone to Sprint with a ticket number given to me by a second tier manager? The sprint store rebooted my phone a few times, tried to make a few calls. Of course it works. So their rule is, if they cannot replicate the problem, they cannot help.
So I guess I am asking what you guys would do. The only two option I see are:
1. Buy a used EVO and finish out my contract(14months) hoping nothing goes wrong with it.
2. Take the early penalty, close my account and go to Verizon like the rest of my friends whose GPS's and calling "just work".
I would hate to leave sprint cause they have the best unlimited deal out there. But this is the second "top of the line" phone I have bought with them that has been a disaster. And both of them seemed to work flawlessly for the first couple months I had them.
By the way, I am on stock EC05, and I have been ever since it EC05 came out. I am not rooted or anything. It was working fine till about Friday.
Do you have TEP?
Wow, try taking out the sd card and use the phone to make a call. SD cards can make the phone do some funky things. If that works; then put it back in, connect the phone to your computer, copy all the contents to your computer; format the sd card and copy the contents back to the sd card.
change to sprint only network (settings - wireless networks - mobile networks - system select .. choose sprint only)
uninstall app 3rd party applications; perhaps something running is the culprit
If still no joy; I would root it and try a custom ROM. Maybe a file got corrupted at some point and that is causing the disconnections.
I really like the one I am on, its worked beautifully.
I'd be happy to help you through the root process if it gets to that point.
Good luck
It doesn't matter whether I have it or not, they rebooted the phone, brought up the dialer, made one call(he might have made two, one of the other people was talking to me) and sent me on my way. If they can't replicate the problem, then their policy is to not do anything. I even asked them if I could make a video of it first hand when I get home, and they basically said that won't change anything cause they have to be able to replicate the problem first hand.

I will try SD card when I get home. I don't have any third party apps, as the technician on the phone hard reset my phone like 3 times. I tried every custom rom, and I even tried to go back to DI18. All of them had the same problem, so I am guessing it is hardware related. Again, data is working correctly, just seems to be something with the calling hardware.

If you have TEP - don't even bother with taking to the store any longer. Just complain enough over the phone and you should be able to get someone to send you a new one.

Unfortunately I cannot really wait for them to send me a phone. I need to get something today, as this phone is also my work phone. Customers do not like going straight to my voicemail :/
After a tech on the phone with Sprint screwed my phone up even worse, had me stuck in an activation loop. He told me to bring it to a Sprint store. Well this was at night so I Odin'd to stock DI18 and let it do the OTA and that cleared up the loop. It may work for you and save you grief.

I've heard of similar things. I helped someone troubleshoot the problem and came up with it had to be the tower. They called again to customer service and of course they said that nothing is wrong with the tower. I think that they called again to make a report to check out the tower near their house. They did that a few times. I don't know how long it took to fix the situation. I do notice lately that, even though signal strength was okay before, it's better now.
If you have another sprint phone, if you activate it, does it do the same thing? This might be one of those instances that if you complain enough, maybe they might give you one of those devices they have (I forgot what it's called) that you hook up to your home internet and it acts like a mini tower at home. I've heard of stories that after enough complaining enough, they'll just give you one. If the phone still does it then it's the phone that's flaky.
When you talk to someone, make it clear you use this phone for work and if people can't reach you, you will lose clients. If you start losing clients because of this then you will be forced to go to another carrier. If they say you'll have to pay etf then tell them you won't because it isn't your fault that you can't make or receive calls at work and home.
This phone or their equipment or service isn't working properly and you're losing customers because of this.
Here's another idea. Find someone else that has sprint. Have them go by your work and home and see if they can send or receive calls. If they can then its your phone, if they can't then it's the towers.

Man, I'd be flippin out if it were me. That has got to SUCK!!
Hi,
I was an idiot and accidentally flashed the LS970_ZERO_EFS.zip without knowing what I was doing. I eventually used DFS to be able to set my IMEI and MEID, which helped get my phone to a state where hands-free activation, prl upgrades, etc. work fine now. All non-cell activity also works fine, but anything that uses cell towers fails. PRL Upgrades and Hands-Free activation work fine. When someone calls me, my phone doesn't ring but I eventually do get a 'missed call' indicator.
I read the 'Backup/Restore/Repair Your EFS Partition' thread, which is how I figured out to how to use DFS to set my IMEI and MEID, but I'm unable to do the 'For 1X/3G working - use DFS' portion of it because I don't have my AAA Shared Secret password and my HA Shared Secret password.
Finally, to make matters even worse, I'm not on Sprint; I'm on an MVNO of Sprint called RingPlus.
What should I do to be able to get cell access working again? Any help at all would be appreciated. Thanks in advance to anyone that can help out! :good:

Thanks! I will try moving my account to a dummy phone, and moving it back afterward. Hopefully that will force the 'initial handshake' that they mention in that article. I'll post my results after I try it out (probably sometime this weekend).
THIS!
OMG this is almost exactly where I am at. I too am on RingPlus, but my journey to a screwed EFS was different, I used Framaroot to root my phone so I could have Titanium backup and other root functions. It was great for a couple of weeks, then one morning I my network connectivity just turned off, that was a little over a week ago. I tried tech support, but eventually figured out that it wasn't my service provider, especially when I looked into my "phone identity" settings and saw everything except my ICCID and PRL were zeroed out.
I was thinking about flashing the clean EFS, but I can't really find out how to do that, I see instructions for it in the EFS restore thread, but all it says is "flash it" and I'm having a hard time figuring out how to do that.
Also, I can't get my phone to root anymore, I tried Framaroot again, and this thread "Universal Root" http://forum.xda-developers.com/showthread.php?p=38886073#post38886073 It says it worked, but Titanium Backup says it still doesn't have root.
And to top it off, my play store says no connection (tried wiping cache and different versions, date settings, can't get it).
Right now, I'm working with an almost useless phone.

If you unlocked your phone with FreeGee, it made a backup of your EFS. Put those files in the flash efs zip and you should be set

Thanks, but I used the Framaroot APK and that was it. I kinda jumped in before I really read/understood what I was doing. I had no idea that information could be wiped.
I have been trying to understand how the whole system is setup and at which points modifications can/should be made.
I don't think I've ever unlocked the bootloader, which is what I thought FreeGee was for, I just used Framaroot to root it and thought I was good. Then 0000000000.
I have been trying to figure out if I really need to flash the ZERO EFS, or if I can just jump to using DFS to modify the ESN etc. It seems like my EFS is already zeroed. (I'd ask in the proper thread, but I'm working my way up to 10 posts...).
Thanks for the reply, there are really so many resources here it is incredible, I just need to remember to not do stupid crap (too late!).

Framaroot was set up as a temporary root. It says that in our root guide. Some use it all the time with no issues. I played it safe with the Universal Root.
The EFS was discovered by autoprime I think, and steps were taken to fix that. Follow his guide's to hopefully fix it.
I wouldn't Zero out anything that is left. They may help you or Sprint fix it.
You're not stupid. LG just has different things to worry about compared to HTC, Samsung etc.
Good luck with everything.

Temp use of a Sprint ESN/MEID for service swap?
Does anyone out there have a Sprint ESN/MEID they wouldn't mind "loaning" me for a couple of hours so I can attempt to "swap" service out and back to my device.
The CSR I'm dealing with says that doing a swap is better than cancel/reactivate because apparently with a cancel/reactivate they actually close the account and any (prepaid) funds in there get eaten (kind of bull**** that they can't do it from some admin position that would stop that from happening, but whatever).
Thanks.

Decided to abandon this line, bought an LG Tribute for $40 and swapped to that. Super small internal memory, but other than that, not a bad phone really.
SOLVED! - see post #7
This SM-N910V is rooted and had 3g but apparently I lost that when mucking around with things trying to get 4g. I've got other phones like a Galaxy S5 and Galaxy Note 5 both Verizon models that get 4g or 3g fine in this same location.
First odd thing I noticed on the Note 4 was a setting that popped up seemingly by itself while in 'More Networks' and 'Mobile Networks' that showed VZWInternet with a circle by that which was not yet checked so I tapped that and it turned green in the circle. I have never been able to see that option again. I don't think this caused the problem though. I've looked at apns-conf.xml in the /system/etc folder and can't see a problem there. I also tried replacing that with another one that is supposed to fix LTE mode. No luck so I put back the original. I wiped cache and reflashed a backup with TWRP which had been working on 3G but that didn't help - no 3g even. I did not wipe Dalvik/ART cache. I had been messing around in the 'Service Mode' menu with a bunch of different settings in an attempt to get 4g working but I'm fairly certain I got everything set back the way it was before I started. I noticed that one setting I had left different in the Service menu did not change back after flashing a restore with TWRP (full restore - all boxes checked). The one setting I left changed was the under the 'AS' protocol menu where I changed the Release version control to "LTE 3GPP REL 9" from LTE 3GPP REL 10". I know enough to be dangerous
Open to any suggestions - am wondering at the moment if I should have wiped the Dalvik/ART cache before the whole TWRP restore? At this point I'd be happy just to get 3g working again.
I also tried Dr. Ketan's LTE Enable. That didn't fix anything. Although I see MNC and MCC numbers in the apns-conf.xml file when I look at the SIM with a SIM info App I just see blanks in those spots on the SIM. Not sure if that's relevant - just giving as much info as I can here.
Did another restore with TWRP after wiping Dalvik/ART cache but that didn't fix it either. Strong cell signal but no 3G or 4G.
More info - I put the SIM card in another phone and it sees 3G at least.
It seems the "lost 3g or 4g" problem is very common and it seems I've looked through dozens of message threads here but I'm not finding any solutions. I'm looking at flashing the 'ltefix.zip' from this thread but it seemed to be for a custom ROM and I've just got the stock - more or less - 5.1.1.
Hmmm.... Been at this all day reading here, searching, trying everything but still no Mobile Data. Is this as elusive as rooting a Verizon Note 5? LOL - it was working at least on 3G. I'll take hints or even wild guesses at this point.
Okay - it finally flashed on me to do a restore of my EFS. Oddly I had done a full restore with TWRP which include EFS but that didn't fix the problem. That TWRP backup was done the same day I did an EFS backup using Dr. Ketan's IMEI tool for the Note 4. When I used the IMEI tool to restore the EFS backup I then had the 3G come back on. This is a 4G SIM so I still don't know why I'm not getting 4G but at least I got 3G back. I did have a hiccup using this IMEI tool which initially caused the phone to repeatedly shutdown after a minute or so and could not be restarted without pulling the battery. I believe it had to do with the 'Restore' button needing to be held down a certain amount of time instead of just a tap. I probably held, released too soon then held longer which I suspect caused a partial or damaged EFS restore. Be careful in how you use this tool or you may end up in that situation. I had to work very fast after a bootup to get it properly restored. After that it was stable again and had 3G.
Now if only I could figure out what it takes to get 4G.
..
I wasn't getting 4G for the longest time, checked the PRL in settings on my GFs phone and noticed my PRL ver was like 50 thousand something while hers was 15518. Got a new Sim card and all my issues went away, PSA do not use *228 programming...EVER.

Update/more info - I've continued to try and figure this out to no avail, although I got fed up with stock unrooted 5.1 and am now running modestrom v9 with a CQI2 base. And all of that install went fine, except for 4g of course.
I think this is worth mentioning as it might have something to do with the situation:
Way back in the beginning, I had gone through the entire unlock/root process, and everything actually worked fine the first time. This was right about the time the unlock became available, I bought the phone based specifically on that being possible, and got a brand new one at that time. Well, it was awesome for about 2 weeks, fully functional 4g and everything.
I had a very particular goal - I wanted this phone totally unlocked, but I was also very interested in the advanced/wifi calling that was supposedly coming out at that time - I was planning to move to a place with no vzw service and would be reliant on wifi for calls at home. Verizon wasn't clear about the fact that the wifi calling feature wasn't coming until MM, and this was before MM was released, so I was running a completely functional, 5.1.1 rom. I believe it was jasmine. So, under the impression that "advanced calling" would have given me wifi calling, I tried to enable it.
I cant recall if it was immediately, or a few hours after, but this is when the phone lost 4g for the first time. I immediately tried to deactivate the advanced calling feature on my line, but it didn't help. And nothing I could do would bring back 4g. I tried everything possible, and ultimately gave up and threw the phone in a drawer and went back to my note 3.
Fast forward several months, and my note 3 began to have issues with call audio, forcing me to use the 3g-only note 4 in order to actually handle day to day business. Again, I went through the processes of trying to fix 4g, with no success. Now by this time, MM had been released, I believe PD1 was the current firmware. I figured at this point it was time to just odin back to 5.1.1 and start everything over.
So I odin flashed the phone, and it booted into 5.1.1......with no 4g. Again I went through all the things I found here, no improvement. Finally, one day when the phone was bugging me about an OTA, I figured "what can it hurt at this point, its nearly useless without 4g anyhow."
And low and behold, the OTA update from verizon booted up and immediately jumped to 4g.
Now I felt I had a chance, a method that I'd finally proven could fix the problem. I left the phone in that state for a couple weeks, just to prove that it was holding. No problems during this time.
But I got sick of no root, and so I figured it was time to try and go through the steps again. And again, I lost the 4g connection. No big deal, just odin back to 5.1.1 and let it OTA like last time......
Except this time it didn't work. So I odin flashed back to 5.1 again, and let it try to OTA, again. I let the phone continually try to OTA all the way up to current, and flashed back to 5.1 at least 3 times to repeat the process in hopes it might fix something. No change at all. At this point I actually began to try and see if possibly Kies could help me here - maybe there was something related to the phones EFS? Which I don't understand very well btw - it was only through reading this thread that I began to research EFS and its significance. I also attempted to use some of the checkboxes in odin - the ones to erase all NAND and to clear EFS and rebuild it. Neither option made any difference. So I figured next logical step was to start playing around in service mode, which would require unlocking/rooting again......
And thats how I landed here. About an hour ago I got sick of the stock 5.1.1 and went through the whole root/unlock process and I'm currently running modestrom on CQI2 or whatever was just most recently posted. Every other part of the phone seems normal, but still no 4g. I can actually see the radio making an attempt to connect in the service mode - but I don't understand service mode menus well enough to interpret where the actual problem is. Upon boot the phone tries about 3 or 4 times to get an lte signal, during this time there is simply bars of signal, NO data indicator of any kind. Eventually, it gets frustrated and gives up, connecting to 3g and staying there. I realize now that when 3g drops, which is roughly every 10 minutes or so, its actually the phone attempting to establish LTE again. But still, I cannot make any sense of this.
Apologies for the giant post - I'm trying to put anything that could possibly be relevant info into one place here.
So........ anyone got any suggestions?

PM sent. Just to share a little of that here I think the first thing I would do is tell VZ you suspect your SIM card is bad and have them put in another one. Tell them it fell out when changing a battery, the dog ate it and by the time it came out you suspect it wasn't quite right anymore - LOL. I do think SIM's flake out sometimes and I know a bad one can prevent 4G from working. If you ever had an EFS backup from anything try restoring ONLY the EFS (if you use TWRP). No guarantees that will fix it but my best guesses at this point. Good luck.

I got a used stock note 4 to try and compare and see what I could be missing here....
Tried new sim card at least twice, unfortunately no dice, and the same card pops right into the spare note 4 and it wakes up on 4g just fine.......
EFS is something I probably should have been quick enough to dig in deeper on before this, as I don't have any backup of it....... however, I'm not seeing any other symptoms, I can see my imei fine, and every other function works. Is it possible that corrupted EFS can cause the loss of just one type of connection like that?
For giggles I tried a friends att sim, and no lte on that either.
Playing with the app LTE discovery, I can tell that the phone sees 4 different LTE towers just fine, showing db numbers exactly in line with the stock note 4 sitting right next to it, theres just something there under the surface thats stopping them from hooking up...... it stops trying after a couple minutes, rejects them all and connects to 3g.
I'm convinced its some kind of software thing, but I can't tell exactly where the failure is happening.....
I also odin flashed it back to stock bpa1, and still no dice. Is there a means to make an EFS backup without root? I want to see what happens if I try unlocking the other note 4 as well, but this time I want to have the backups......

I've been running on Emotion 7.1.1 for months with NO issues (well, some minor stuff, you know....)
Suddenly, two weeks ago I got a notice from Google that I had to sign in on my phone. Verrrryyy odd. At first I suspected some hack attempt, but my Account checked out fine. Having changed my password recently, I had to wait until I got home to login.
After I logged in, all ~appeared~ to be OK. Then I opened my Calendar. B L A N K. All ten years of appointments gone. I freaked out. I have two calendars, one for personal stuff, birthdays and the like, and another with my business appointments, INCLUDING FINANCIAL STATUS of the account. Gone.
Went online on my PC, signed into Gmail and switched to my calendar. Empty. Looked in Trash. Nothing. Vanished. Nada. Niet. There's a long story here about recovery efforts, troubleshooting, Googling, etc, suffice to say that TWO separate, redundant, backups had quietly failed, without the notifications they were supposed to send. I did manage to get from the first week in April back 10 years, but lost the whole summer. Thank YOU-KNOW-WHO that I'm good friends with all my clients.
Fast forward to last week. Suddenly I get 3G only from my Verizon account. Like you, I spent days on the boards, downloading ROMS, wiping, re-wiping, trying everything short of smoke signals to get it back. No joy. I did NOT go back to stock, I must thank you greatly, as that was my next road. Now i see it's a dead end. I will NOT give up my Nougat root just to get 4G.
Perhaps this is a bit conspiracy theory sounding, but I've become convinced that Verizon is playing some game, perhaps to force us to upgrade to a new phone. I learned long ago that corporations have no soul, and will do anything they like to increase profits. They exist for two reasons; to make money for their officers and to make money for their stockholders. Any other semblance of a "Product" or "Service" exist ONLY and SOLELY for that reason. Anyone who is a Yahoo or AOL member knows the level of intrusive ads and attempts to trick people into putting spyware in their machines under the guise of "protection" or "cleanup" programs has jumped to a new level of absurdity since Verizon sucked them up. "Oath" indeed. It's what is coming out of existing customer's mouths! M O N E Y H U N G R Y.
When I chatted at length with a Verizon Tech, she made it clear that she knew the answer was to upgrade to the latest stock (I never admitted to rooting, but she knew, we spoke "between the lines" a lot). She sent me a SIM card, but it., of course, didn't fix the problem, in fact it would not even initialize properly! I had to go back to the original SIM.
Now that we've found a way (after YEARS of trying) around their stupid block on rooting, they change the game. What person who is so into their phone as to root it, will put up with 3G? This is something Verizon is playing at, Sprint too from what I gather.
My only consolation is that I've got so many WiFi's nearly everywhere I go, and when I'm not near one, my Wife's Note 4 (not rooted, on latest update) works fine. I'm glad I decided not to root hers too.
Frankly, this really ticks me off. I have better things to do than spend days copying files, flashing and reloading data. Verizon knows that, and let me tell you, it won't be THEM who sees my money when I finally do upgrade.
Thanks again for saving me from the Stock route, you saved me hours of grief.
Peace out!

I have run into 4g issues with this as well and almost came to conclusion is a modem issue. I want to say but can not confirm that modems that are flashed are relative to bootloader on the device. Just something I've been pondering on as I had a unlocked bootloader device and flashed for wife to use with no root and recently unlocked again.

The phone recognizes the SIM card but there is no signal (no service). Tried several things, including flashing a custom ROM. I'm considering buying a new motherboard and changing it myself, but first want to know if anyone knows more about this issue or has an idea/suggestion.
Edit: As an added bonus, something that only now I realized. Now when I charge it, it gets EXTREMELY hot. Like I-can't-even-use-it hot. I used to use the phone while charging all the time, but now I can't even hold it. Seems like the problem is when it tries go past 80% charge. It gets super slow, keeps trying and gets hot. Now I don't know if it's a software problem caused by the various flashings or if it's something that would remain even after swapping the motherboard.
Edit 2: I did a full discharge of the phone and recharged it while turned off. It seems to have normalized the battery problem
Edit 3: RIP. I tried to remove the screen before deciding about buying a new board. In the process, I ended up tearing the digitizer flat cable apart. Now I don't think it's worth it buying both a new screen and a motherboard.
The full story and things I've tried
My phone was working all nice and dandy until it stopped having signal/service. Wifi works normally, but anything related to the SIM card doesn't, like phone calls or mobile data.
A list of things I've tried somewhat in order (both of time and of complexity):
* My SIM in another phone: it works normally, so the problem is not the SIM itself
* Another SIM in my phone: it doesn't work, so the problem is definitely the phone
* Using the second SIM slot
* Changing "Preferred Network Type" between the available ones (4G, 3G, 2G, including Enhanced 4G LTE Mode on and off): this one and the next two items don't really make sense to me, since these options seem to be only related to mobile data (4G/3G internet) connection, not to phone calls which is also not working, but I tried them anyway
* Manually selecting the network: Errors with "Selected network unavailable" and, after trying to register for a while, toasts another error saying "Can't connect to the network, try again later"
* Manually selecting the APN: Tried both selecting between the two options available and manually adding an APN by googling the correct info for my carrier
* Simply booting into fastboot and restarting bootloader: a video on YouTube claimed that it was a temporary solution and that I'd need to do it every time it lost signal. But it didn't even work the first time
* Disabling CQATest and then restarting bootloader (and also clearing its data/cache and removing its permissions): a lot of videos on YouTube claimed this was a solution, including for other Motorola phones. Apparently CQATest prevents the phone from working properly in some scenarios. But I think only when you de-google your phone? Not sure. All I know is that it didn't work either
* Using the phone connected to the wall charger: I think this was another YouTube suggestion, and it actually worked for a few minutes. But I guess it was just a coincidence, as it never worked again
Now for some more... "forceful" attempts:
* Factory Reset: Not sure where I saw this suggestion, but it was pretty much the next logical step. Gathered courage, backed up all my data, etc, aaand... nothing again
* Flashing another ROM: Guess it was here at XDA that I read that it was a problem with Motorola's stock ROM. That, paired with my belief that it could still be related to CQATest being installed, I again gathered more courage to flash a custom ROM. I chose LineageOS and found out that it was no longer supported, but decided to install the last official release. I also read that the problem was the Pie modem firmware, so it all seemed to be going fine since the last official release is Oreo 8.1. I flashed it and BAM it worked! ... for a few minutes and never again. I messed around with LineageOS, tried some of the previous things again, but nothing.
Then, I tried to restore my TWRP backup but it didn't work. So I searched a bit more and downloaded the Stock Pie ROM, flashed it, and closed the bootloader. And then I realized the restore probably didn't work since my backup was made using Pie and my phone was on Oreo. Maybe some files/partitions were missing? Also, when I was creating my TWRP backups, I tried creating a full system image backup but it kept erroring. Only later I realized the problem was that the USB Drive was FAT32 and the full system image was bigger than 4GB. Oh, well, now I know.
So now that I'm with my phone pretty much back on square one, I take it to an authorized repair shop. The clerk said that it was a common problem, and that sometimes it could be solved "by software" and that they'd try that. The other option was to change the whole motherboard, which they didn't do because it was "not worth it" and "almost the full price of a new phone". After two days, my suspicions were confirmed: they didn't fix it with their "by software" attempt. At least I didn't have to pay anything.
When I got the phone back, I put the SIM in again and it showed the icon as if there was signal. But when I tried to call someone, the signal disappeared again. I tried searching a bit more, went through all pages of Q&A here at XDA forums and there were like 3 posts regarding loss of signal. All without any response. On YouTube, I found some videos offering a suspicious .bat file. Upon inspection, it merely erased the modemst1 and modemst2 partitions and then wiped user data and cache. I tried it, nothing to lose. Also didn't work.
Now I'm contemplating a few options:
By watching some disassembly videos, I saw that, when opened, the phone has some parts that act like antennas. I thought that maybe those were not properly connected to the board? Maybe they got dislodged during a fall? Seems unlikely tho, since they are screwed in. I searched for a new motherboard to buy and it's a reasonable price. But I'm afraid it'll have the same problem (or develop it in a short time) since I can't find anywhere what the true cause of the problem is.
Another option is to just give up, buy a new phone and use this one as if it was a "small tablet" lol
So, do you guys have any other suggestions or ideas as to what might be the problem? Maybe a tip like "solder a wire to this spot to create a make-do antenna"? I don't really know where else to search.
If not, thanks anyway for those who read it all
