[Q] Nexus 4 & 4.6 beta 1

Hey paranoids, I finally got around to flashing the new beta last night using the Paranoid OTA utility. I didn't include any other zips with the procedure.
This morning I unlocked my phone and it was just a black (backlit) screen. After about a couple minutes of letting it do its thing I went ahead and just forced a reboot. After coming back, everything seemed to be back to normal until one of my emergency contacts got in touch with me and said she had received a strange text from me. Turns out that Cerberus had wrongfully detected an unauthorized sim card. I have had Cerberus for as long as I have had this phone and that's never happened, so it would lead me to believe that it was the fault of the new version of PA. Any ideas?
I am also having trouble with my device constantly locking itself while I'm using it. I don't mean while watching videos, I mean while actively scrolling or typing or otherwise actively interacting with it.

I am not an expert, but could your SIM card be bad?

G4 Bootloop

Hi Guys,
i am really confused and a little bit angry. The Following happened to me today:
My Phone (Unrooted, Locked BL) was behaving weird this morning.
It just randomly crashed and wouldn't boot up.
Eventually i got it to boot once or twice, but still it crashed, shut down and Bootloop.
A Reqular Factory Reset did nothing. now i'm trying to install the Regular KDZ-File for the H815, but things are just not working as expected.
Has anyone else had this problem before?
Is it normal that the LG Flash Tool is on 1% for over 5 Minutes and nothing changes on the Phone screen?
I want to know what has broken my phone so bad, cause this time, I just used it the way it was supposed to be used, no hard drops, no rooting, no changing of software in any means.
First LG Phone and it broke with no warning and no explenation. I'm a little disappointed right now.

The same happened to mine. Are you able to get to download mode by powering off your phone and plugging it into your computer? Im able to flash stock ROMs but nothing helps. The phone reboots by itself at random times and makes it into the operating system a few times but is never usable.

Hey,
yes i can get into download mode.
I am able to flash files, but the phone wont boot up anymore.
I just want to save my data, but i guess i wont be able to do so.
So i have to get to the store and get a new g4
Luckily i made a backup of my two weeks ago, so not much will be lost.
I also send an email to the LG customer Service, will post their reply here too.
I am really disappointed by LG at this point, i usually had motorola phones and they didn't have random errors like this one.
I switched to LG, cause G4 sounded awesome, but this error is making me sad.
I am really thinking that i won't buy another LG Product, which is making me sad too, cause usually most things made by them are great.

//==============First Request by me:======================
Hello dear LG-Service Team,
i just bought the premium product LG-G4.
Since some days, the Phone is beginning to hang and reboot, resulting in a bootloop.
Sometimes the phone boots, than optimizing Android for about 30 minutes (100+ Apps installed). After this happened, i kann use it again, but not fully.
To shortcut eventual questions:
The Phone is in factory State, no Custom Rom installed. The bootloader is locked and the Phone has not been rooted.
The mistake seems to come from your firmware.
I am really disappointed, because i paid a lot of money and no have a product which is barely usable.
I switched to LG because of the G4 and i don't want to regret this decision.
Kind regards
<<Esok>>

Email and response, translated by me, so there might be some mistakes...
I don't like the response, it feels like not being taken seriously.
Well, nevertheless, i will go to the retailer and will see what happens.
I will keep you updated.
What do you think of this response?
Greetz Esok

That response is terrible lol. I called in and they said they do not support my phone because it is an international version. So there was nothing they could do for me.

I have a similiar issue, but mine was due to a OTA update, and I didn't know about the download mode until now.
Thanks.
Any tips when I can get into the download mode? I just wanna recover my personal data (images, and texts)? Flashing STOCK image would preserve the personal data right?

While your phone is off, plug it into your computer while holding volume up. If you are using LG flash tool to flash a .KDZ firmware file, you will come across an option that says Normal flash or CSE Flash. Normal flash will not wipe data, while CSE Flash will. I have flashed stock images and it didn't work. Hopefully it works for you though.

+1 I'm in same boat and exact same issue with my H815. I love the device but this is unacceptable.

I'm having the same problem, it just happened to me all of a sudden and now I can't even get to the boot animation. I've been able to get into recovery 2 or 3 times but usually it just restarts before it even gets there. I recently updated to the newest xposed framework (though I've restarted just fine a few times after I installed it), did anyone else here do the same?
When I get home from work I'm going to keep attempting to fix it, I've flashed my current TOT but it failed after rebooting. I don't know if I'm having the same problem as everyone else but I'll update if I can find a solution.

same issue here on the at&t 810. Starting about 3 days ago I started getting random reboots + bootloops. Sometimes it would boot to the LG logo and stick, sometimes to the AT&T logo and stick, sometimes to the OS and freeze after the lock screen appeared. I can get into the OS and use it for awhile, then it will restart and it all begins again. 2 factory resets so far and no dice. I am rooted on 10e but have a warranty device on the way which undoubtedly will be on a higher firmware and will likely miss out on the potential coming bootloader unlock. At this point I am probably going to sell on craigslist and get a 6p. The phone is great when it works and I love the size, the looks, and the screen, but the lag and these reboots are unacceptable.

Just a short update by me:
I gave it to the retailer, they said it would take about 10 Days.
I hope this stuff won't happen again or this was the last time i am buying a LG Product.
I think i would have been better off by sending it directly to LG but nevertheless, maybe giving it to the retailer will make my warranty stay longer
I will keep you updated, including firmware Version the phone has after sending it in and so on.

All of the sudden my phone today just froze leaving me with a black background and no animations, the phone is very hot if I try to use it on that moment. Even when I reboot the phone stays very very slow and says system it's no responding.
What can I do? Even when a Reboot it some times works normal then suddenly does it again.

Sounds like a heat problem in your case.
What happens if you pull out the battery, wait 10 minutes to let the phone get cold and than reboot?

Well, no luck on my end. I could only even get into recovery one out of every 50 times or so that I tried, and when I managed to I wasn't able to sideload any system software because it wouldn't initialize the driver (my computer recognized the phone just fine, except the ADB portion). Clearing the data did nothing either. Luckily I'm on Sprint and the phone's being recalled anyway, so I just walked in and they swapped it no questions asked. At least after flashing a TOT and clearing the data they shouldn't have an easy way to tell I was rooted or anything.

Thanks for replying, I completely restored phone today and was a success. No more black background.

same random rebooting issue here as well. and I just bought this phone brand new from a 3rd party :/
Update: I seem to have gotten past the problems after updating to 10n. Now running stock debloated 10n rom with no reboot issues (so far)
Update 2: Had 1 - 2 cycle bootloop on 10n

I don't see how you giving your phone to your retailer will extend your warranty. That makes absolutely no sense, since your warranty begins from your date of purchase.
My phone also ended up with the bootloop and having to exchange with a new unit. I'm on the TMO Variant H811.

Actually German Law is a little bit different.
Regular warranty is not what i meant in my post, i meant the "Gewährleistung" its an additional kind of warranty given out by the retailer.
There are some cases in which this "Gewährleistung", which usually lasts for about 2 Years is made longer. Mostly this happens when the retailer would have to send in a product for the third time, they basically give out a new one, which will be treated like a NEW device. So new Warranty, new "Gewährleistung".
I hope this somehow made sense

Today i got my phone back.
They repaired it.
Everything is like it was before, so i am pretty sure they didn't change it.
Firmware Version is 10d.
The Phone is working so far.
Will keep you updated if anything changes.

Random Reboots?

I was just wondering if anyone else has an issue with their Note 4 rebooting randomly with no external input. This started happening with the Android 6.0 update both on the download from here and the AT&T official release, Any Ideas? I've already purchased a new battery due to a separate issue, any idea?

I had the same problem. The phone would freeze and randomly reboot. Sometimes the system crashes and asked me for the typed-in password (not fingerprint). Sometimes when I charge the phone, and unplug the power cable, the charging led stays lit and the battery has to be pulled. I decided to switch the battery with my wife's Note 4 and see if the effects remained. So far I haven't had any problems after switching the battery, so I believe the battery may be the cause of all these issues. I'll keep you updated on the issues.

I'm back. The battery replacement didn't fix the reboots. I think my phone's hardware is permanently damaged. :crying:

can you downgrade to Android 5.0.1 and help me with my problem?
its something completely different to this topic

I've been having the same issue, started about 2 weeks ago. phone would start being sluggish then if I continue tapping on screen, it'll reboot. At least once I saw it go into recovery & reinstall firmware(?). Another time it just sat at the bootloader screen waiting for software download or something till I took out the battery. Most likely it's a software issue related to 6.0 update or updates afterwards. taking out the SD card helped a bit.
but basically got annoyed & upgraded to LG V20 today. Coincidentally, there was another person at the AT&T store with a Note 4 having the same issue.

Mine just rebooted twice on me a while ago, first is emergency calls only now the reboots then what. And yes the slow charging is a problem too. MM got serious issue dam att

use wakelock its an app u get it from play store.it makes ur cpu always running.some how it fixes the problem of random reboots. dl it and set it to partial lock (the 5th option)

Same problem. Just started a few weeks ago. REALLY frustrating having to enter my password every 3-4 minutes. NEVER buying another Samsung, too many damn issues with this phone.

My reboots tend to happen once the phone goes below 60% battery. It's fine above 60%. Once it goes below 50%, the reboots tend to happen with any intense network activity. The phone will often go from 50% to 22%. I forgot what the 30's and 40's look like. I will try the Wakelock app.

Ugh. I posted about this a few weeks ago. It's started happening more frequently and will occasionally go into a boot loop or show 0% battery even though there's a charge.
Has anyone found any solution? I haven't tried wiping / resetting but I'm getting close to trying it.

Here is a cautionary tale for you. My completely stock, unroooted phone started acting the same exact way. On the 4th or 5th battery pull (to fix a frozen screen) it just crapped out. It's totally unresponsive. Deader than a door nail. Tried everything. The download mode, discharging by power button depression/battery removal, etc. Adb shell command does not detect it. Nor Odin. Computer throws up a qhsusb_bulk error when I plug it into pc. I have NO CLUE how to fix it & I am desperately seeking a solution. Please proceed wisely with your oddly acting phones & don't let this happen to you.

Same issue. Just got off the phone with Samsung support, all possibility of having this particular phone with this particular issue sent in for evaluation has been suspended. Translation, they know it is an issue and will not stand by the changes they push to their products (latest OS). I am researching the prospect of legal action since THEY pushed the new OS against my request. Shouldn't that affect the warranty or coverage? Consulting my attorney friends as we speak. Will let you know. I am not sure how WakeLock will help, it is not going to sleep, it is repeatedly power cycling through a kernel process until the battery overheats or it reboots.

Same issue
Since Marshmallow, my 910A will get sluggish or freeze, shut down, sometimes reboot and sometimes just brick (temporarily). Sometimes--more often in recent days, I get a "dll_mmc read fail" message and the target that says do not stop downloading. No matter what I've tried--factory and soft resets, cache clearing, battery pull, replacement, and SD card switch, contacting AT&T and Samsung rep--it doesn't seem to change. This is a daily issue and becoming more frequent. Any suggestions or do I just need a new phone? Thank you.

LG G3 freezing and restarting, staying in boot loop sometimes

Hello,
Since 2 weeks ago my phone has been started acting all weird. It started with my Phone freezing and restarting itself one morning. It showed the LG logo for a few seconds, then went black and the same thing repeated. LED did not start blinking at first but after a few loops the LED came on, the animation played and phone turned on nicely. No more such problems during the rest of the day.
Fast forward 2 days. It got worse. The freezing and restarting happened more often and at one point it was in the LG logo -> black screen -> LG logo loop for a good 10 minutes before it booted. It also drains my battery about 10% every single time.
So I decided to do a Hard Reset when I managed to keep the phone running long enough. The hard reset process itself worked flawlessly, no issues during the reset what so ever. I though the problem was over until a few minutes after the hard reset when I was reinstalling my apps, it froze and restarted again.
I started googling about the issue and found a few matches. Some people suggested replacing the battery and some suggested putting a piece of paper between the battery and the SIM card slot from which I did the latter. That actually worked for a few days until the reboots came back and it got worse by the day when it finally was completely unusable since it kept restarting after booting up (usually it didn't even get to that point). Then I decided to try a new battery because it was the cheapest option available at that moment.
At first all looked good on a new battery but still, just a few minutes after rebooting the phone from a new battery it froze yet again and restarted itself. So 25€ wasted on nothing.
At this point I'm starting to run out of options and really would not like to buy a new phone since my G3 is only two years old (warranty just ended in October 2016).
Any suggestions are more than welcome at this point.
Best regards,
Taavi

Yesterday I tried flashing the stock V30B marshmallow ROM onto the phone using LG flash tool 2014. It lasted without restarts for about an hour and then it all started again.
So in conclusion:
A) It's not the battery.
B) It's not the software.
C) Thus it must be the hardware.
Since my warranty is void already, the repair costs would probably be quite large.
I think the only chance left for me is to suck it up and buy a new phone.
It was fun while it lasted though. RIP.

Funny thing is that after I removed my SIM card, the issues have stopped for ~24 hours. Yesterday I was able to browse reddit and watch videos for almost 2 hours straight with no issue when I had no SIM card in the phone. I will try inserting the SIM card again after I have fully recharged it to see if maybe it has something to do with the SIM card connection.

Put in the SIM card and it didn't even last 24 hours before restarting. Took it out again. Unfortunately it now restarted even without the SIM card so it still must be some hardware failure.

Same issue here. Changed battery, factory reset, rooted and TWRP+CyanogenMod 14.1 flashed and SU granted.
Constant reboots. Sometimes bootlooped until I remove battery

Having the same problem. Tried new battery but it turned out to be a cheap clone that was worse than old battery. Got another from mbuynow which last longer but still restarts but not that often. Tried the paper trick to to avail. Also tried the LG suite to see if it helped but no luck. Running marshmallow 6.0 and have done a full reinstall. Is this likely to be hardware problem?

Cannot tell for sure but seems it is a hardware problem which is really sad since besides the restarts the phone is still in very good shape. I would take it to repairs but as my warranty is already void it would make sense to simply buy a new phone and sell the current one to parts.

I have the same problem... I flashed CRDroid or something with Android 7.0, it booted normally, but then, restart after few minutes... It can boot normally with the usb to computer, but not with charger. It can also boot to twrp, wipe, install and fix the system works, installing other roms works too, and they can boot normally, but it shut down, as soon I remove the cable... I thought it was nougat rom, it change some in system files or drivers like battery options... I'm out of options...

I have 2 phones. This thing seems to puff exactly after 2 years coz they were bought in difrent times and both of them emerge this issue after 2 years for each. boootlops were after few minutes from start. In case of first one new battery was a bingo but i did not investigate second - im going maybe for new phone. Funny thing. Maybe product life time was to planned to good(for producer)?

I was a great phone, longest I have and most customised... Very agile, never had bricked, bootlooped or failed to flash... Thank you for your great support, LG G3.... Rest in Peace... If someone can bring it back to life, I'll be back to that.

I'm counting on someone stumbling on a fix as well. It's still an awesome phone expect for this stupid thing.

I had similar issues but I realized that different SIMs seemed to work with the phone. Went to my carrier and requested a new one. Since then, no issues. Maybe something with the sim card slot?

It happens even when my SIM card is not in the phone. It could easily be the SIM card tray but cannot confirm without taking it to repairs.

Did you try disabling Location?
(I had random reboots when the battery went to 25% and when i disabled Location services,it got fixed)

One of the hard resets I did was from full charge and I didn't enable anything, including location. It still went into the reboot loop.

It might be a hardware problem in some LG G3 phones.
It began rebooting and bootlooping after 2 days,that i had disabled the location services.
Now i'm thinking of getting a new battery but i don't really think it will do any effect..
So i might buy a new phone..

I had the same problem as you,i bought a new battery and everything got fixed.(you need exact the same Model of battery so when you go to a store note the model of the battery)

Temporary Fix
1- Remove the SIM, turn on the phone, put it in Airplane Mode.
2-Insert the SIM turn on the phone.(Don't change Air mode).
3- Turn off auto backup/restore in settings.
4-Go to network setting>Preferred network Type.
5-Turn Off the Airplane Mode and immediately SELECT THE 3G only(Before it catches the signals), in some phones WCDMA only.(Do not Select 4G/LTE/2G).
6-Done
7-Restart the phone.(Now it will not reboot)
Drawbacks:
In 2G signal zone, There will be no signals.
Its a hardware problem,But its a way to trick it.

SMT700 screen flicker & reboot issue - kinda solved

It started about 8 months ago, in retrospect, after an OTA update. I'd be looking at some app when the screen would flicker and shortly after it would either go blank, reboot or simply turn off, it was maddening and I thought the end of my little tablet. I tried a couple of different things, thinking that somehow the bootloader got corrupted I reflashed that, didn't work. I then flashed the previous version of the bootloader, that really didn't work so flashed back. I'd always kept the tablet with the stock Samsung ROM so flashed the latest Lineage ROM (great piece of work) but that didn't help and actually made it worse, when I would reboot it seemed like it would immediately flicker when things were updating, it wouldn't stay on for more than a minute. I read about the potential for cracked battery leads so changed the battery and reflowed the solder around the terminals, that didn't solve the problem either. After that I started to suspect some kind of memory/software issue so in desperation I flashed it back to the beginning of time, the original Samsung ROM and that worked. I have the TAR if anyone needs it just let me know. After you do this your back to Android 5 and you'll notice that it will notify you of OTA updates, I updated BUT I found that past the 4th update the flicker came back, this might just be an issue with my tab but just be aware. I only use this now to read the news or my Kindle books, I did notice that some apps would trigger the flicker like My Radar or Zillow so I uninstalled them.
Hope this helps.
