FIX for no signal/sim/constant reboot issue - Galaxy Note5 Q&A, Help & Troubleshooting

I've recently seen several threads from quite a few people who have the issue of having no signal, no recognition of sim card, unknown baseband/imei etc., and rebooting every minute or so after turning on.
Its happened to me 3 times now but the last two were fixed as another user had found out how to fix it so ill share his discovery that I used for this issue successfully. Ive posted the steps on a handful of different threads by users in need but hopefully this will save the extra threads and duplicate comments by myself as its hard for me to not comment with help when i am able to do so.
The exact cause of the issue is not known to my knowledge. It happens after flashing something. Can be supersu, a kernel or even a rom, and when booting after the flash you find you have no signal bars or even a spot for them, if your quick you can see under phone status through the settings menu it shows unknown baseband, unknown imei, everything that looks important unknown and the inevitable reboot, my system uptime was 1 min 05 sec each reboot. I tried flashing a rom which still had the same time of reboot but appeared as a bootloop as it never fully booted the new rom and rebooting preventing it from fully setting up...until....
1. Bottom line im 99% sure is to let your phone completely die. Others just so happened to be a certain way during this such as having the sim card removed and/or being in download mode. I followed the exact steps the user did, remove sim card, let phone die, reinsert sim card, charge a little and reboot. It worked. I had sim card out and was in download mode as one user had his sim out and another was in download mode when they fixed theirs. I do see the importance of being in download mode only because my phone has died before but i was able to boot to download mode a few times before it was truly out of juice. Seems as if letting it die resets whatever it is that is causing the phone not to read the information. Let it completely die, be sure to either be in download mode or boot to it after it dies until you cant anymore. Really doesnt hurt to remove sim as well but id bet that it is overshadowed by completely running battery out which then I am sure the phone wouldnt know if it even had a battery let alone a sim card or that it is a phone to begin with.
2. After the battery is gone completely, reinsert sim if removed, and charge it before booting, but just a little maybe 10%, just in case you have to let it die again if the issue is still there. Download mode takes forever to drain battery, the constant reboot drains pretty well and if you are desperate you can make it vibrate between each reboot by switching vol up/down vibrate-silent, fast enough and it almost vibrates nonstop for each reboot. I let it get down to 3%, then booted to download mode to think about what its done and die. Then I waited a few minutes, plugged in charger, booted up and was good. I had flashed a kernel, then got issue, had fixed it by this method, but su had disappeared so i flashed supersu and got the issue right back, so dont charge alot before knowing your for sure good.
3. I just realized im terrible at making steps or howtos and have lost the plan i had imagined for these steps.
BASIC EASY FIX- LET PHONE DIE, CHARGE PHONE TO 10%+, REBOOT PHONE. ISSUE SHOULD BE FIXED. OVERLY DETAILED STEPS ARE ABOVE TO PREVENT ANY CONFUSION OR QUESTIONS FROM THE TECHNICAL USERS AS WELL AS THE USERS, AT LEAST APPEARING, TO NOT HAVE ANY TECHNICAL EXPERIENCE AT ALL. (which is ok)
Tired of posting over and over across forum on new threads having the same issue. Hopefully it directs you here and if not idc ive done my deed for this topic and as hard as it will be for me to do i am not repeating on any future new threads. Theres been quite a few which is not a terrible thing but just detracts from the forum in general. Also this isnt even my fix, i found it same way you should have but credits go to a s6 thread by whoever that user was in their q&a forum.

Help diagnosing freezes and random reboots

I am hoping someone has dealt with either of the following problems, and come up with a way to effectively diagnose and fix either.
The phone - 1101 build; running AT&T Stock KK4; rooted via kernel swap method (using stock KK4 kernel after swap, i.e., do not have clockwork recovery); some AT&T bloatware frozen with TiBu, otherwise stock with root
Problem #1 - roughly once a day, the phone will freeze when in sleep mode; I have had this happen with both the slide to unlock and Exchange PIN lock screen up; when I hit power to wake the phone, the screen wakes up but is unresponsive and then the screen won't shot off again; live wallpaper is frozen in place, but if the phone was plugged in, the battery icon continues with the animation loop. And if the phone is not plugged in, battery power drops rapidly in this state.
The phone isn't completely dead, because if I connect/disconnect it via USB (set to debug mode) to my laptop, the computer recognizes the phone is connected, but it is dead enough that if I call the phone, it does not recognize the missed call. The only way I can restore the phone is a battery pull. Usually it takes several minutes for the phone to come back after this, acting like it would if I had flushed the dalvik cache or installed an update.zip from recovery.
Problem #2 -also roughly once a day, at random times the screen will wake up momentarily, then clear, and I will hear the AT&T boot up sound, after a short while, the phone will run through the media scanner and any other startup launches, acting as though it had been turned on, but the battery stats show continuous uptime throughout. I have had this happen when using the phone, including when on a phone call (and the call did not drop).
I have seen problem #2 on virtually all of the AT&T GB leaks, and it seems to get more frequent the more apps that are installed. I had not seen problem #1 until recently.
The phone is out of warranty, and owned by my employer. I am not due for a new phone from them until July. I've done more master clear/reflash stock cycles than I care to admit, tried replacing/testing for disk errors the external SD card, etc..., and am afraid of doing that and having the problems come up again.
Any thoughts on how to diagnose either of these problems?
Hmm... I don't really think there is an exact diagnosis for any of these issues. Some phones are just problematic like that. The only thing I can suggest is trying a different ROM or kernel, and that might help your stability.
I have the exact same problems. Hope someone comes up with a fix. The only help I can give you is that when the phone freezes, instead of pulling the battery, you can hold the vol up & power buttons for 10 seconds and the phone will restart. Easier than pulling your phone apart, especially if you have it in a case, like I do.

So, the way I see it, unfortunately these problems could be a function of:
Bad hardware
Misbehaving app
ROM issue
Kernel issue
I tried pretty much every leaked AT&T GB ROM and had random reboots with all of them. Seems to track with the number of apps installed, but can't prove that. I have not tried any custom ROMs or kernels.
Since this is technically not my phone, I am trying to avoid doing anything that can't really be undone if I need to turn the phone back in at some point. And I need something that can be a daily driver for work calls and Exchange email, and rely heavily on tethering when I am on the road.
Anyone with ideas on what to test, or how to capture enough log information to figure out where the problem is, would be a big help. Otherwise, I am stuck riding this out until July when I can get a new phone from my employer.
Nothing you do can't be undone, it's just a simple Odin flash away.
Be sure to back up your efs folder before flashing too much

I've used Odin with the various GB leaks; if I go further afield (heck, performance is dicey already, how many more problems could I have with one of the ICS alphas), is it still a straight shot back to stock KK4, or are there other steps to do first?
And before I go down that road, any suggestions on diagnostics (other than yet again pulling apps off of the Captivate to see if one of them is the culprit...?)

You actually might have less problems on ICS. But it all depends. You can always get back to stock with one, bootloader-free, safe flash. Diagnostics wise, there isn't really much you can do besides removing apps. I would only worry about the ones that are constantly running in the background, as they could possibly be screwing with the phone while in sleep. I think it's unlikely that this sort of testing would actually help though. I still say try something different.

I am having the same issues except in my case I have tried to recreate the conditions and check memory and I am close to maxing it out. Part of my problem is that I come from a Palm background and I have found that Android, or at least the Cappy, is not as responsive (I was really spoiled by Cards on my Pre) I was thinking that my Android noobness is causing me to push the phone too hard and locking it up. FWIW, you might want to check memory issues

[Q] XT925 hard bricked - battery failure during factory reset. Halp

Hi guys.
First post, apologies if it is in the wrong place.
I was given a Motorola XT925 3 days ago, running what I can only assume is the most recent version of android (i tried updating it, and it claimed it was up to date). No SIM card in, no SD card.
All was well, until I noticed an app, "media" sucking 50% of the battery. It was killing me, so I did some extremely brief Googl-ing and arrived at the conclusion that a factory reset would be a sensible thing to do to nip the problem in the bud.
Unfortunately, my battery ran out half way through the reset (derrrrrrpppp), leaving my new phone semi-hard-bricked.
The loading icon will come on sometimes if it's put on to charge after some time off charge, and sometimes the stupid little robot even pops up, with a loading bar underneath him, and a tangled blue web protruding from his abdomen. He freezes a short time later.
The power and volume buttons are unresponsive, and the whole semi-booting pattern is erratic, but things seem to happen if I leave it off/on the charger all day.
I have a suspicion that my phone in it's current state has half the operating system un-installed, and will therefore not boot correctly.
Anyway I was hoping to get some recommendations for the most appropriate next step. I will be taking it to a nearby shop tomorrow, and see-ing if the people who sold it to the person that gave it to me can help...
I have read about "flashing" devices etc, and if the shop-people can't work it out, I'm probably going to give it a try. I am running a mac as well, so many flashing programs will probably be incompatible.
Thanks for the help
tl;dr: Motorola XT925 hard-bricked following complete battery depletion during factory reset. Wat do?

[Q] A very strange rebooting problem.

Regarding: Samsung Galaxy S3 Mini GT-I8190 - SIM unlocked version
Hello eveyone.
I'm having one of the strangest problems I've encountered with a phone before and I just can't seem to track down the problem. Please read this thread with an open mind as from what I can tell this is a unique issue that sounds like normal issues.
The main problem is that the phone keeps rebooting. From the get go this sounds like a normal issue with either the battery or power switch but here is the weird part...
It only happens when the phone is fully charged!
IBackground
I have had the phone since release and I have only ever used the stock rom that came with the phone. I don't really use phones much n general except for using it for calls texts and BBC news. I didn't even have a SD Card in it until after the problem started. Everything was running great, I never had any battery problems at all, and then a couple of weeks ago my phone contract expired with Orange and I decided that I would get a SIM only plan with EE.
While waiting for the SIM card to arrive in the post I charged my phone up one day and noticed that I had to power on the device. The phone seemed to power on fine, I could use all features of the phone, but when I turned the screen off for more then 5 or 6 seconds the phone would restart. There would give no indication that it had turned off or that it had powered off in anyway. It would simply just be blank, I'd press the power switch, and it would vibrate once and begin its start up procedure as if it had been turned off completely.
Here is where it gets weird, the phone will keep cycling on its own like this until the battery drains itself through constant reboots until about 85% juice, at which point it begins to operate functionally.
I heard that some people say they had problems with the power switch. I figured that if it was the power switch it then the problem would be consistant and would continue giving me problems when the battery was below 85%. I think I can rule out the power switch as faulty. Naturally I came to the conclusion it must be software, perhaps an APP installed which was incompatible. I tried all sorts of things, regardless I came to the conclusion it needed to be factory reset. Factory reset didn't do anything, still does it. My next thought was Firmware, it must be the firmware that was corrupt. I went through tutorials and rooted my phone, installed recovery software and ended up installing Cyanogenmod 11 (Which looks really beautiful btw, wish I had done that sooner) and buying an SD Card too do so. Still the problem persists! I read that some people had problems with swelling batteries, I replaced the battery completely just incase. £10 wasted, still does it.
At this point I'm starting to get confused. I started thinking perhaps it was the cable providing too much charge to the device, over charging somehow. Tried a different cable and a different power source. Still the poblem persists. I made sure there was no dirt in any of the connectors incase that was causing something. No joy.
So to summerize:
1. Factory Reset
2. Replaced Battery
3. Changed power leads
4. Cleaned device
5. Flashed to completely new firmware
I've completely run out of ideas on what it could be. Why would the phone operate absolutely fine under 85% power? Its just weird! I'd appreciate any help some one could provide me. I've not seen any one else with this problem on the internet. Please let me know what you guys think.
Thanks
Craig.

Sorry to hear about this man!
I am completely stumped on this one! You've basically done all the basic solutions but to no avail. I had a problem similar to this where my device would reboot randomly, whenever it wanted to and in my case, the solution was to buy a new battery and that actually worked. I've had the battery for almost 2/3 months now and it's still going strong.
Back to your problem, I honestly don't know of a solution. I really wish I could be of help but as I said, you've already tried the basic solutions.
Again, sorry to not be of much help!

I think I have the same problem as you did. After suddenly dropping and rebooting, my battery level jumps back up when the phone starts, and again, and again. The phone is functioning normally only when plugged in. I also presume that it is a battery problem, but the fact that the battery level rises back after dropping, makes me wonder.
EDIT: Problem solved with buying a new battery.
Sorry to jump in, just curious, did you solved this? If you do, hope to hear your solution, might help others in future

[Q] Hard briked S3 mini out of nowhere

I have the feeling I'm going to get repetitive here guys, but I've been reading the troubleshooting threads for over an hour and couldn't find an answer to help me.
Last saturday I was to lazy to move from the couch, so I watched as my S3 Mini ran out of battery. I got the "phone is turning off" screen as usual. Later I went to bed, but as I needed my alarm to go off in the morning I tried turning it on again, and nothing* happened. Plugged it on the wall, nothing*. Replaced the battery, nothing*. Gave it a good half hour plugged, and as you can guess, nothing*.
* when I say nothing, I mean it won't light up, won't vibrate, won't wink for me, won't load any kind of error, it's actually just like if you were trying to turn on a phone without any battery connected, no grasp of life comes from its poor soul.
The only moment I could see some action on the device is when I tried connecting it on the PC a few hours ago, as it installed drivers to Windows. Right after installing the drivers however, it won't show in the file explorer. I've tried to detect it with a few development tools such as ORT and Odin and there was no sucess either. Download or Recover mode will not work as well.
One thing I think worth mentioning, is that ever since I rooted it a couple of years ago, whenever I tried to recharge it while it was off, the standard "green charging battery" would never appear. What would appear on the screen was a freezed loading icon (the one that keeps roling again and again, but frozen). This particular issue never came off, even reseting it or installing new ROMs.
I always used Maclaw's, some of the latest 4.x, because I tought the 5.x was to heavy for the s3 minis.
I've read some about USB JIGs and stuff, but what makes me very curious is what the heck?! The phone was working just fine, the battery runs out and I have a brick? Is this possible? Can anyone tell me any work around?
I apologize for possible grammar mistakes.

try to plug in the phone into charger & leave it there like 20 mins or more. battery loads then.
then try access samsung download mode, if you cant the phone is probably useless (brick for ever) because itslike mthe last standing thing.

Hi there,
Thank you for your interest but I have passed this point already. Tried a brand new battery I had laying down in the drawer (which was fully charged with an universal charger) and there is no answer to any attempt of turning it on. Via recovery, download or normal boot.

Hello there,
I'm sorry to hear I'm not the only one affected by this bug (lets call it a bug). This shows there is a lack of concern from Samsung on dealing with this issues, and thus we see that old programmed obsolescence.
I will try that later on the weekend, and I come back here with an report.
Cheers

Thank you for your interest but I have passed this point already. Tried a brand new battery I had laying down in the drawer (which was fully charged with an universal charger) and there is no answer to any attempt of turning it on. Via recovery, download or normal boot.
Hello there,
I'm sorry to hear I'm not the only one affected by this bug (lets call it a bug). This shows there is a lack of concern from Samsung on dealing with this issues, and thus we see that old programmed obsolescence.
I will try that later on the weekend, and I come back here with an report.
Cheers

this guide useless for you. how u want flash things with odin if u cant enter download mode at all??
im really sorry for you that this phone is dead. just can give you 1 advice, dont buy samsung in future.
I have been repaired my phone successfully!!!
I just needed to change two capacitors on its motherboard, and that's it.
Here the video where I have found the info and how to do that. It's in Spanish but easy to understand for you I think. But if you need some help, send me a PM.
can you take a picture from the location of the 2 capasitors and the types of it
Hi everyone.
I have some news. It took me a while but I followed CrashOverride93's advice on that video. It actually solved one issue, as I now can turn it on, but now I have a second problem, I'm stuck on a boot loop, with acess to Download mode ONLY. No recovery.
Considering where my issue started, and where I am now, I have tried the following:
- Flashed via Odin stock ROM, kernel;
- flashed Wipe;
- flashed PARAM;
- three button combo.
So far I couldn't get it pass the boot loop. Any thoughts?

Recovery without losing data

I have a Moto G6 XT1925-5 (64GB version) which doesn't want to start up. It's all totally stock, been updated to Android Pie.
It gets as far as the boot animation, and does that for about 2 minutes, then it boot loops and starts all over again. When it bootloops it gets stuck at the first Moto logo screen (not the animated one) for about 3 minutes before carrying on to the boot animation...
This happened once or twice before, we left it overnight and eventually it started up normally. But it's now been five days and it still hasn't started.
I'm not very experienced with Android hacking/modding, etc but willing to try anything. I managed to get into recovery mode and at the top it says (I presume this indicates the firmware version):
motorola/ali_retail/ali
9/PPSS29.55-37-7-6/16c5a7
Unfortunately USB debugging is not enabled. Is there anything that we can do to recover the data that was on the phone before we wipe it - or is there another method we can try to get it to start up? I saw there's a command adb logcat which looks like it might be useful to diagnose the problem but that also requires USB debugging.
Thanks in advance for any suggestions
There is no chance for you to recover your data in this mode.

Thanks for getting back to me so quickly.
There are several other modes available from the bootloader BP Tools, QCOM, etc but I can't work out how any of them are supposed to work.
One question - on the recovery menu, there is an option 'Mount /system'.
I pressed it and it says at the bottom /system mounted, but then there don't seem to be any obvious ways to access anything.
Is there a way to use this to access OS/kernel logs which might give a clue as to what is going wrong?
Thanks again
Step by step...
The first level of the system, which is accessible for you, is called bootloader menu (fastboot menu). From here you can boot into recovery, system, bootloader itself and some other options you mentioned in your post.
None of these options would help you to solve your problem. These are developer's options.
This level is more or less a one way data connection. The main advantage of this menu is to flash single partitions of your device. But there is no way to get a data output of any partition.
In recovery menu you find the options to wipe your data and to mount /system. Mounting /system won't help you, too. This partition doesn't store anything of personal data. It's read only and not writable for anyone. To be honest, nobody knows exactly the meaning of it in this context. Also you won't access any logs from here.
Generally you can't access the system logs. These informations are only buffered data which is cleared with every reboot. The error message of e.g. the kernel log produced by your system when having a bootloop, is only accessible while your device is looping/freezing. The next reboot erases the logs. They aren't stored somewhere on your device. Even for developers it's very tricky to view the log in such cases.
But what would you do if you get the reason for looping? You are not able to access any system partition. You need root user permissions for that. But rooting your phone will erase all data.
Apart from all that your data is encrypted and remains encrypted until you unlock your screen by fingerprint, PIN or password. No chance to get any useful data as a "third person" outside. It would take several years to decrypt it without the matching key for it.
Thanks so much for this detailed explanation, I really appreciate that you took the trouble to answer the questions in detail and explain what the various options are for.

No problem!
Maybe you'll find some of your personal data in your Google Drive account...
How the story ended
Thought I'd come back and post in case it's useful for anyone else:-
Due to a religious festival, we left the phone switched off for three days. After the festival ended, we switched it on, and immediately it did the same thing that it had been doing all along (spend a long time on the initial boot screen then a while on the boot animation before boot looping). Bizarrely even though it had been off it did not prompt for the PIN code.
We then held the power button as though to turn it off (but for some reason, throughout the usual power button never actually turn the phone off, it always attempted to restart immediately) and then next time it came on it asked for the PIN and started up normally!
So all in all that was a grand total of 9 days after the problem first happened. Very inconvenient not to be able to use it for 9 days, but it's now working again. We haven't dared to try to restart it since!
Some closing thoughts:
The storage is very full (99%), we wonder if that had something to do with this problem
We have now enabled USB debugging and bootloader unlocking to make recovery easier in future

When I read this last post, I immediately think of a sticky power button, because if you keep holding the power button after the phone has booted it will turn off again, and start up again. And it would also explain the weird behavior you just described of not turning off but rebooting straight away. I'd say: see if you are able to clean de button with a very thin needle or a crafts- or surgical knife around the edges, is might just solve your problem...

Thanks for that suggestion. Interesting, not something I'd thought of.
For now the phone is working perfectly, provided that have to restart it (i.e. we make sure not to shut it down or let the battery run out) but I'll definitely bear this in mind if the issue happens again.
The power button is working normally to turn the screen on or off meanwhile.
Thanks again for your input which is really appreciated.
First time trying to restart after the above
Since posting the above messages the phone has been kept on all the time and not restarted.
Today for the first time we accidentally let the battery run out and the phone shut itself down.
We nervously plugged it in and tried to switch it back on... and it started properly first time, so perhaps the underlying problem was simply that the storage somehow got too full (in the meanwhile we have transferred many photos and other media to the computer and deleted them off the phone to free up space).
Posting this in case it helps someone else experiencing a similar problem.
