My flex2 stuck on att screen after data recovery attempt

My flex2 stuck on att screen after data recovery attempt - LG G Flex 2

My battery went out on my gflex 2 so I ordered a new one and switched back to my old phone while waiting for it to come. Some time while my phone was without a battery it started acting weird. I could hook it up to a rapid charger and use it while charging. So I would check my email etc that way then switch back to my old phone. When I got on it one day I realized half my apps were gone and I couldn't update or download anything on it. All my apps showed 0.00b in my settings as well. So, I tried a hard reset. I backed up everything went to my settings and clicked data recovery and when my phone tried to reboot it froze on the att login screen. I did the power button and volume down thing a few times hoping it would work but the same thing happens. I had the new battery in all day and the phone was working (still having it's download issues but functioning).
I have not attempted to root the phone. It has been unlocked by att for a year or more and has always worked fine until a few days ago. How can I fix this? Will my phone still be unlocked if I have to redownload the software?

Phone stuck in Reboot loop

Posted this on reddit but figured might be helpful on here.
Did some testing with the phone with very little apps for the last day. Decided to go to the play store and go to my apps and started DL'ing my apps I mostly use basically everything that's on my G4. Phone froze rebooted OK whatever, rebooted again, again, ok stuck in reboot loop. Called Alcatel was able to do a master reset took maybe 10 mins for it to load back up in Android everything is froze and just reboot loops again.
I can't even power if off well I can but it power's back own and does the loop. Waiting for the battery to die. Now here's a reason why removable battery is great.
Seriously WTF happened.
After talking with Alcatel and Amazon they are sending a replacement with 1 day shipping be here tomorrow. Wonder if I should even bother with it. Was going to mostly use it for my 2nd line for a Hotspot for the Data and just a backup to my G4 and or rotate them.

Now I do recall after it first froze and rebooted it said Android is updating or whatever that screen is. I recall the phone having 2 updates it updated though the day before. Should have the replacement on here later this evening.
I had CPU temp app running so I could see what app were heating up the phone when I used and when I had Google Maps on it the car it did heat up to the low 70's C once in awhile and was sticking mostly around 67-69C did the phone get too hot. Not even sure what the overheating temps are for this.
Probably just a defective phone but was fine running basically not added apps just installed NoChromo, Battery Monitor Widget, CPU Temp, Netflix, Rhapsody, Signal Check Lite, Speed Test, Spotify, I believe that's what I had installed before the issue. Then I just went and download everything else I usually use at once.

More than likely either the 1st or the 2nd update applied to your phone put it in a bootloop but you would have had to click on them to allow them to install. Going into recovery via rebooting till you first see the alcatel screen and then holding down vol up would have allowed you to do a factory reset which in all previous cases of boot loop being mentioned corrected the issue.
If it wasn't the updates then one of the apps downloaded did not work well with the phone but a factory reset should still have fixed that, unless you were installing apps that use superuser in which case you should first have at least booted twrp and backed up system if not all the partitions so you could do a restore. Remember these suggestions for your 2nd phone.
Ideally we need someone to back up system both before the 1st update and the 2nd so we could "downgrade" if necessary. Some have complained the 2nd update caused a bug that makes making google voice calls unavailable.

warranty repair..the easiest anf fastest way at this situation.

I installed both updates before doing anything with the phone. The phone was fine for 24 hours or so. I did the power button and volume reset with Alcatel and it was able to reset it just fine but still was stuck in the reboot loop. Not sure why one of those apps would have cause it to do that but maybe it was defective and one of those apps just finally pushed it ? I was not trying to Root the phone at all, atleast not right now I'm not. Don't you need to flash TWRP for root if so I don't have access to that and not doing that at this time.
I did get the replacement one yesterday as promised. Turned it on downloaded and installed the update. AFAIK it only downloaded and installed 1 update for me this time. Not sure if this is the current build 7SQR-UER0 but that's what I have after the update and it showing it's up to date. The build before it I checked was 7SQ3-UE30 that's what came on the 2nd phone I don't recall what was on the 1st phone.
I just set it up and went to play store and downloaded everything didn't have any issue's so well test some more the next few days. Could of just been bad phone.

If you have not yet rooted and have any model other than 6045i (settings, about phone) you could really help the idol3 users out....details here: http://forum.xda-developers.com/idol-3/general/want-to-able-to-install-ota-updates-t3163745

I believe that is the model I have what ever the USA bought on Amazon.com are.

I have rooted successfully with king root. Tried to change it to Supersu but failed su binary i think because Im on 5.1. Also is it actually boot looping or does it just not load. Because mine will boot up say Alcatel One Touch then be stuck on boost mobile boot screen for a while. I unplug battery and try again and just leave it. It takes a long while but it comes back

why you root it with king root, when there is a procedure to root the device with custom recovery?the device couldnt be running android 5.1 becaouse we all have only 5.0.2. How you manage to unplug the non removable battery?

HTC One M8 reset itself?!

The other day, my phone died midway through a call. When I tried to turn it on, the 0% sign showed up meaning it was completely dead. I had to urgently make a call so 30 mins later, I held the power button again, turned it on, and the phone went to the white HTC screen and then turned off. I finally got home and connected to my phone to my charger after. I let it charge for a bit then turned it on. I knew something was wrong when my phone was hung on the red Verizon boot logo for a while. Minutes later, it went past the Verizon logo and a pop-up appeared that said optimizing app 1 of 44. I thought this was odd because I already got the MM update about 2 weeks ago and since it updated, I never saw that message ever until now.
Once my phone gets past that and finally boots to the homescreen, I realize that a lot of things have gone wrong. First, I got signed out out of all my accounts (Whatsapp, Spotify, Instagram, Facebook, etc). On top of that, my call history was cleared, all my text messages were cleared, and all my contacts that were saved on my phone storage were gone. In addition, I also had to re-update a lot of apps including the HTC ones that you have to upon the MM update. Finally prior to those whole thing happening I had 10.7gb of free space. After this episode, I lost exactly 1 gb of storage and only have 9.7gb free.
I don't understand what could have caused this or why I lost all this data on my phone. Moreover, it doesn't seem like anything was deleted but my phone is just not reading anything that was already there.

mine just did this exact same thing after shutting off from a drained battery. It's like the data partition or whatever got wiped. Right now trying to log back in to everything and set EVERYTHING back up again. This sucks.

i came here for the same thing. mine happened around the same time. only thing i can add here is that my storage is almost maxed out on the phone. makes me wonder if that had something to do with it. but then this happened to two other people around the same time. very weird.

The exact same thing happened AGAIN! I was at the gym listening to music and texting some friends while my battery was at 15%. Went from 15% to 10% in a matter of mere minutes and then from 10% just shut off. Couldn't charge it until I got home so I just kept it in my pocket. Got home about an hour later, put it to charge and then turned it on when battery hit about 10%. Same damn thing, got stuck on the Verizon boot logo and then the dreaded Optimizing Apps message showed up. Once it finished, I was logged out of all accounts, updates to system apps were gone, and widgets/BlinkFeed were gone/reset. And just like last time, suddenly 1GB of storage was gone.
Literally un-freaking-believable. I dreaded that it would happen when my phone shut off and yep, my fears were right. Going to do a factory reset once I backup everything. From there, I am debating whether to replace the battery or replace my phone. While it sucks that it happened to you guys as well, I am somewhat glad its an HTC issue and not just an issue with my personal phone.

Same thing happened to me at 40%

This was recently brought up in the viper rom thread, could be of help.

Your battery needs to be reset. Hold down POWER + VOLUME (can't remember if it was up or down. takes about 10 seconds)and let it keep resetting and keep holding it for 3 minutes. then let go.
It'll fix your battery so that it drains to 0 instead of 13, but it doesn't fix the weird pseudo-reset problem. It's a known issue and many people are struggling with it. My advice is to set EXTREME POWER SAVER to auto-on at 10%, and if you ever see it that low, just turn it off yourself until you get a chance to charge it.

Same thing has been happening to me since the MM upgrade. Before that I had NO issues with my battery so I find it hard to believe that my battery is the problem.
After the third time of this happening I finally decided to to a factory reset. This did not help, phone continues to die anywhere between 15% - 30% and revert some of my settings back to stock.
This is driving me insane as I rely on this phone for personal and work use.
Decided to call HTC support today, I did not expect a solution but wanted to make sure it was reported. Of course they had no idea and claimed to have never heard of this issue.
I am guessing that since the M8 is over two years old we wont be seeing and fix pushed out for this issue. I really like my phone and dont want to upgrade at this time.

Finally somewhere where people are actually having the same issue. I've tried factory resetting the phone, doing a fresh install of the OS (with firmware recovery tool) all with no avail. I note lose all my settings and app configurations every time the phone dies, shuts down or restarts. I hope there's a fix, otherwise it looks like a custom rom is the only way.
Has anyone tried wiping the dalvic cache? I can't get into the recovery on my phone so I can't try it, but heard I it might help.

Had the same issue last week
I was at about 20%, phone shut down. I plugged it in to charge, went to boot it up, and it got stuck on the Verizon bootup screen.
I waited a while and did a hard reset, and it came back on, but was completely wiped. So I had the same problem, which is a real pain, because I use the GOOD app for work, and each time that re-installs I have to get a new PIN. And I have had to re-install the app a few times in the past month for a variety of reasons...

I feel your pain. I use Mobilepass for work and every time my phone resets it deletes my token and I have to request a new one.....
Here is what I did two days ago that seems so far to be working for me. I calibrated the battery. I have tried this in the past but could never get the calibration to work properly. Each time I tried I had the phone plugged into the charger. This time I didnt and the phone went through the battery calibration process like it is supposed to.
Since I have done this my phone will stay on until it gets to 8 or 9% and then shut down but when i charge and turn back on all of my setting are still in place.
To calibrate the battery I held the up volume, down volume and power button (all 3) for a full 2 minutes without the phone being plugged in. During this time the phone will start and get to the HTC splash screen then shut back off, start again to the HTC splash screen then shut off, repeat, repeat, repeat.... after 2 minutes release the buttons and let the phone boot up, plug it in and let it charge to 100%.
I hope this helps,

This happened to me today. I let the battery get a little lower than usual last night, around 13% before shutting it down and plugging it in for the night. Turned it on this morning and it booted up normally. Didn't lose any apps or data, but every time I did something on the phone it gave me those little hints like its a brand new phone. I went to settings and it says it was factory reset at 6:46 a.m. this morning (about the time I turned it on).

Did it reset your ringtone and notification tone settings? Thats what it always has done to me.

I would just like to say that the same thing happens to me as well on my HTC one m8. Battery suddenly dies, now even at 25%, even after a calibration which is just a temporary solution, and when I turn the phone again, SwiftKey settings erased, everything went to stock, messages and contacts are preserved, but the apps start updating itself even though they are not allowed to and I have to manually set a lot of things. It is a total confusion and I literally can't believe HTC allows themselves to not issuing a fix for this disaster.

Was it cold?
Same issue. With mine it seems to be when it gets cold. I was skiing today in 20F but inside my pocket this really shouldn't be an issue. It has turned itself off and refused to restart several times when it has been used to take pictures in cool weather (I live in western OR, it doesn't get COLD, by cool I mean <35F but >20F, usually > 25F). This is the third time it has totally screwed up the phone when it has happened. On another occurrence it reset under normal conditions too. I'm getting pretty sick of it as it is quite a process to get all my VPN tokens reset, get all the apps back etc. Of course it waited until the warranty was out to start acting up.
This time is especially bad, the phone will not restart properly and important processes just constantly flag as stopping so that I can't even get past the initialization screen. It looks like I will have to do a full factory reset. If anyone from HTC is reading...Not acceptable and I won't be buying another phone from you.
Unfortunately I've reached the point where I wouldn't be surprised if it is a programmed planned obsolescence function, but whether or not, this is really annoying behavior.

Sorry to hash up an old thread but I put up with this crap for 5 months before I finally punched and broke the screen out of rage during an important business tech support call when I was at the clients location trying to service their security equipment, it was so embarrassing having to tell them I have to come back especially since it was a remote location.
Mine would wipe contacts, texts etc regularly. I ended up installing Super backup or something and saving my backups on google drive and just restoring everything everytime it happened.
I decided to fix up the phone and replace the battery, broken charging port and smashed screen and unlock bootloader and root but flashing superSU didnt work, got stuck in a bootloop. Anyways through all this I wiped all the caches (including Dalvik cache) flashed the correct stock rom and did the battery calibration and that seemed to have solved the random shutdown and memory leaking issue.....but I guess I wont know for a while.

I have a HTC One 610, and like every once in a while it well automatically reset it self whenever I am in the middle of a text message, on facebook, or even sending an email on phone. Its getting annoying when my cell reset its self.
what needs to be done to it? and should I do.

try a factory reset

I know its old but people are having the same issue still so I'm gonna paste this everywhere i find this problem.
There is a Modified stock rom named "Android_Revolution_HD-One_M8_53.1" and its almost the stock M8 without bloatware and so much more stability improvements. So hear me out and flash it with a custom recovery (i did it with twrp) and it seems to be working fine so far. Give it a go before you trash your -still so good- phone to the open seas.

Well, this issue is still happening. my phone has been doing the same for about a week now. ive made several attempts to reset the battery and had to reinstall back ups every time its happened also. the only difference i think now is that its happening at 90% instead of the usual 15%. ive been following instructions to hold volume up, down, and power (with the phone off) for about 2 minutes and then letting go. i have my extreme power saver set to come on at 15% but Im not even getting that low before it shuts off and resets. i have however noticed that recently that if you plug the phone on charge after it first dies you can avoid the phone resetting.. this may be a fluke but its allowing me to deal with the battery problem now without the loss of my data, contacts, etc.

This is exactly the reason why HTC One M8 is the last HTC phone I will ever purchase. Imagine the hassle of phone factory resetting on its own. Horrible.

Damn phone stuck in bootloop!

Came home from work yesterday and the Pure XL was dead, said it needed to be charged. Never happened before but I figured whatever and plugged it in and went to sleep. Woke up this morning and powered on the phone and the all white BLU splash screen came up and then the phone went off. Came on again and the all white BLU splash screen came up and went off. Ive tried holding down the power button for over a minute. Tried holding the power button and volume keys to boot into recovery from 10 seconds to 2 minutes, nothing stops it! It just keeps rebooting. This has been my apprehension towards purchasing phones with non removable batteries. The boot recycle happens about every 15 seconds and the phone vibrates everytime it boots up for the past 2 hours. Its getting very annoying and there is no way to make it stop. Any help would be greatly appreciated.

Plug it into your computer (you'll notice that there will be a longer black screen in-between the bootloops) and hold down the power button for at least 10 seconds or more, then release it after the next vibration and the white BLU screen shows up. It might take a couple of tries.
If you manage to boot into at least recovery but can't boot into the system, then try clearing your cache/dalvik cache and try rebooting into system again.
If all of the above doesn't work for you, then your boot.img/system has gone bad, and you'll have to flash the stock images with SP Flash Tool (both of which can be found on other posts on this forum).

follow the instructions on the SP flash tool thread... sounds like what happened to me after bad flash... theres a lot of information in that thread that will set you up...

Thanks for the quick replies guys. The PC trick didnt work at all. I just called BLU and asked for a replacement(havent heard back from them ironically). I put the phone in the basement so I wouldnt have to deal with that incessant buzzing every 15 seconds. Eventually the battery died. Since I had it powered off finally, I plugged it in for about 10 minutes to give it enough of a charge to power on but not stay on to buzz for another 2 hours. This time I powered it on using the master reset button combo and was finally able to wipe the cache and restart the phone. Took a good 4 or 5 minutes to boot after that, but everything has been fine since. Really dont know what initially caused the issue, never happened before. Good thing too, cause BLU told me that they would send me a RMA within the hour and I still havent heard from them. Think this will be my last BLU phone. Thanks for the assist.

My phone Is stocked without root or Twrp. And I find my self having a bootloop once a month for an odd reason. This forces me to take bat out and put it back in or just let it loop til battery dies

My phone is basically out of the box and I'm getting boot loop problems when I first boot. This happens like once a month
Sent from my PURE XL using XDA-Developers mobile app

This happened to me for first time yesterday. Bought the phone earlier this year and everything worked fine. I restarted the phone because my sound recorder app froze up twice on open and the infinite boot started until the battery died. Tried the {power}{vol up} thing, didn't work to stop it, so I put it in my car and went back to the conference I was attending. Battery was dead when I got out. Contacted BLU by phone and they started a ticket for me, but I figured I'd see if other people were having this issue and learn what they did because I'd rather not be out of a phone for however long it takes for BLU to replace mine. Stumbled on this page. I never rooted my phone. And BLU only sent one wireless update since I've had the phone. I'm trying to get into the menu by connecting to the computer. Worked the first time, I cleared cache, and tried to backup my files, but I'd taken out the SD card in expectation of sending it to BLU. So, Powered off the phone, put the card back in, and now I haven't been able to get the menu back. Still working on it, if there are any suggestions anyone drops on me before Tuesday when I'll likely ship it (or at least hope to because I'll be yelling at them Monday), I'd appreciate it.

I tried to flash the phone, but the bootloop apparently wouldn't allow that. I had 0.0% progress after 3 hours. I then tried to go back into the menu you get from {Power}{Vol UP}: still no go. So, I started to take the phone apart again to get ready for shipping. The battery was still low so it didn't take long for it to die after I unplugged it from the computer. Out of curiosity, I tried to repeat finding the menu like I did earlier that day (conditions were that the phone had no charge when I connected it to the computer, and my SD card was removed.) No go. But, then I hit {Power}{Vol Up}{Vol Down} just to see what happened, and boom. My phone loaded up. No loop... Figured somehow the files had copied and the status bar was wrong. Turned the phone off, put my SD card back in and turned the phone on. Loop reappears ...I waited for the phone to die again, took out the SD, attempted to turn it on and the loop was there. Connected it to the computer and hit all 3 buttons, and the phone loads up. So, now I'm confused. Is there any way that the problem is some crappy connection to the SD?

ATT LG G3 D850 Recovery Issue

I have had nothing but problems with the two G3s I have had. One had a broken screen (not its fault) so was retired. One the screen started doing this weird backlight problem. So I swapped out the internals from one into the other. to make one good one. Both the same exact ATT LG G3 D850s.
Worked fine for a year. Then today the phone just turns itself off. So I tried to turn it back on, no response. Remove the battery, turn back on. Looks like it is going to boot, gets to the ATT screen, then loops back to boot again and again.
So I said screw it, everything on it gets backed up daily, so lets factory reset it. No go, it starts to do the factory reset then reboots over and over.
So I said fine, and started to follow this guide:

I downloaded the proper TOT and DLL files, but when it goes to do the update, it says Model Information CHECKFAIL
Any thoughts? I do not care if I have to put a custom ROM on or whatever, I just need it to work for a few more months.
Thanks!

Update today.
Not sure if this is a battery problem or hardware problem. I do not think it is a software issue. I suspected a battery issue, which is why I tried swapping them before. I have two genuine original LG G3 batteries. One used for a year and one for two years.
I decided to say screw it and see if maybe sitting overnight with the battery out did anything.
I have two batteries, both were at around 70% originally. I think through testing yesterday one had gotten up to 80%. I had tried swapping them at various times yesterday while troubleshooting. I put one in again. It came up and started optimizing apps like it was doing the reset. I said ok great! But then it crapped out after like 5 or 6 apps. So I put in the other battery, and it made it through the entire process and has been staying on without issue.
The thing is, it would stay on the DOWNLOAD MODE without issue before, so I am not sure it is a battery problem. But I am wondering if there is a problem now with both batteries where if it gets below say 70% it doesn't work.

i have fried my wifes samsung note 4 please help!!!

I recently bought a used galaxy note 4 for my wife, the phone was bought from a tech guy that worked in a Samsung store.
the phone had been loaded with the note 7 firmware, this was a little glitchy and began crashing the phone.
I assured my wife that I was able to flash the stock software back to the phone, I have done this before on other phones and tablets etc.
the software flashed across with no issues and the phone worked fine..... until my wife restarted the phone, it wouldn't boot up until I removed and replaced the battery, assuming that there was a glitch with the firmware I factory reset and wiped the partition again then re flashed the stock firmware, again the phone worked fine and sailed through the initial set up, once it was up and running I tried to reset the phone to test it.........
now the phone wont turn on, it wont charge, it wont boot in recovery or safe mode.... I have had the battery in and out many times and have held the power button with the battery out to discharge power......
the phone is dead! is there any way back from this or do I accept I need to start looking for a new phone for the wife!!!
