Sprint LG G4 won't boot after update - Android Q&A, Help & Troubleshooting

Hello, I have a Sprint LG G4 and I recently downloaded an update. After it restarted it got stuck on the Sprint startup screen for about 40-45 minutes so I decided to take the battery out because I could already tell something went wrong.
Keep in mind, I have not rooted or flashed a rom on this phone as it is completely stock.
I went to the Sprint store and after the guy punch stuff in on his computer for about 20 minutes, he told me that the "tech" could fix it by factory resetting the phone. The only issue is, I would like download my data off the phone before I reset it and the people at the Sprint store didn't know how to do that.
I there a way a way I could get the files off of my phone before resetting it?

[Q] Vibrant warranty and replacement?

Hi everyone,
I recently began experiencing network issues on my Vibrant (would not work on 3G, only EDGE) which did not go away with any troubleshooting steps.
Yesterday, it crapped out completely and refused to connect to the network at all. No calls, no data, just a "Not Registered On Network" message. It wasn't the SIM card either.
I did a soft reset, hard reset, factory reset, and ended up flashing the latest Bionix rom (1.9?) with Voodoo and the whole deal. That still didn't work so I called T-mobile and requested they replace it under warranty.
So my questions are:
1) The phone is not only rooted, but flashed with Bionix 1.9 (JAC UV Voodoo). Will that cause problems with the warranty?
2) If yes, would flashing to a stock ROM fix that (disable Voodoo and restore from Odin)?
3) If the warranty is VOID, what will TMO do?
I asked the rep but she wasn't very helpful at all.
Thanks!
You coyld just delete everything on the phone all apk all apps and send it in all there going to so is reinstall there info when you send it back I don't think that they communicate with eachother about stuff like that if they did customer service would know more about flashing roms and actually be able to help more when something gos wrong other than a series of resets
The guy on the couch
I would flash it back to stock via odin... why take the risk they might say something. Its easy takes and takes next to no time to do.

That's what I'm thinking too. I'm going to do that. Does that clear root though?
@willsnews, I'll try that too. I don't want any trace of my stuff on the phone anyway.
replacement phone
ezspassov ... mind sharing the status of your replacement? my tmo samsung vibrant (18 days old) crapped out on the 12th within 24 hours of receiving the JI6 update from tmo. phone will no longer boot. got it to boot a couple of times but all the apps force close even after a user data wipe (guessing it's a hardware problem). tmo was to express ship out a replacement but today the order status was changed to BACKORDERED! did you get your phone or is it also backordered?

Yes, flashing the stock rom through odin will remove any system traces of root. On the other hand, make sure your smart and delete any evidence manually through the file manager on your internal and external sd card. For example: Don't leave a bunch of zip files lying around named "Root", "Bionix rom", etc....Be smart...

That's crazy because I am having the same issue actually. I had to order a new one.
Anyway, the loyalty rep assured me it would be easier for me to just do a warranty exchange (and assured me it would be brand new, which I doubt very much but eh whatever) instead of of sending back this one and doing a whole new order and waiting long times for my account to be credited and all this crap.... anyway I went along with it. Well I called today to get the tracking number cause she told me to and found out it was on backorder. Hoping it isn't on backorder for to long cause I want to get to enjoy my phone fully.
I asked if I could just send this phone back, they could cancel the exchange, and then place a new order (the backorder is only for exchanges they told me) that way I know for sure I am receiving a new phone cause I am still under the 14 day buyers remorse period but after a 20 minute wait, yes 20 minutes, they came back and said they couldn't place the order at all (I was going to pay with my cc).
So I said eh whatever just go ahead with the exchange in hopes that it won't be to long before they come. I know the rep told me they've been on backorder since the 13th, smh.
So..
So what if I had flashed nero beta 2 and the phones rooted and not only can I not enter clockwork recovery anymore but my phone isn't recognized on the USB ports so I can't Odin back to stock. I get the "USB device not recognized" even though I've manually installed all samsung vibrant drivers. How would I go about erasing all the data now? Any help would be great cause I'm not sure what I can do with the phone now.

[Q] Get rid of custom logo when turning on Samsung Galaxy S4

About a month ago I safe rooted my Samsung Galaxy S4. I never ended up doing anything with it, and I never had any issues. Then about a week ago I got an update for Android 4.4.2 and now I can't use Google Play, YouTube, Google Drive, or anything with a Google account. I get the "Can't establish a good connection to server" error. I know it was my device because a friend of mine, who never rooted his device, had the same update and everything was working perfectly for his Samsung Galaxy S4. So I waited a while and tried the connection again. I tried on my internet, his internet, my data plan, and my school's internet, and every time it was the same error. I was starting to get a bit aggravated. I went online and I saw ways to fix it by checking date and time and confirming they were correct, doing a cashe and data clear, and hard resetting my phone. My phone no longer had root due to the update, but when I did a hard reset I still get the Samsung Custom logo with an unlocked lock when I turn it on, also the issue is still not solved. I do not know what to do and I am very upset because I thought this would be quick and I need to use my phone. How do I get rid of the error and how do I actually reset my phone. Remember I cannot download any apps because of the error, and I can't fix the error because I am assuming the update screwed something up on my phone. I was told safe rooting does not void warranty, but I have a feeling I was lied to when I safe rooted. Please help me fix this stupid problem, I do not have the money for a new phone.

[Q] i545 in constant activation mode

Okay gurus, I need some help.
I purchased a Galaxy S4 i545 for verizon used on craigslist. When I bought it, I went with the guy to the Verizon store and watched as he had it removed from his account. The people at verizon told me the phone was clean and there were no issues. Several weeks later, I took this phone to verizon and tried to replace my current phone with this one.
When they boot it without a sim card, there is no issue. As soon as they put a sim card in the phone it automatically goes into some kind of automated activation mode dialing out over and over again. There is no way to break the activation cycle other than pull the battery. The people at verizon are now telling me there's something wrong with the phone.
Thinking maybe he had it rooted or unlocked, I followed the instructions here http://forum.xda-developers.com/showthread.php?t=2578209 to put the phone back to 100% stock (including PIT), but still there is no way around this issue. (See Attached screenshot)
Anybody have any experience with this? Can you help me out?
Ultimately, I was going to switch this over to PagePlus after using on VZW for a month or so.

[Q] galaxy s3 no longer connects to 4g. 3g not staying connected! HELP!

I bought my s3 in March of this year, and everything was working just fine until May. It's an awsome phone and I love it. However, since May, my phone no longer connects to 4g EVER and the 3g comes and goes and never stays connected for more than 10 minutes while in use. I've NEVER even come CLOSE to reaching my plans provided 2.5GB of data, so I know that's not the issue. The phone has never been dropped, or wet, as I am always very delicate with my phones. I have never placed it too close to the TV...
I contacted Boost mobile. They gave me a long list of things to try. I have tried EVERYTHING: making sure the mobile networks is checked, preferred network setting CDMA/LTE, soft reset, clear browser cache, update PRL, profile update, software update, firmware update, ##72786#, and even did a factory reset. Nothing helped. Boost said there was nothing else they could do for me, and that I needed to contact samsung.
Samsung said the only way for them to find the problem is for me to send them my phone, and wait 2 to 4 weeks for them to revise it and send it back. That's not an option as I need my phone monday through friday for my job. (UPDATE: I got so irritated with this problem that I went ahead and bought an LG Volt, since I didn't have the money to buy another galaxy. It's nice but I don't like it as much. I'm still afraid to send the Galaxy into Samsung. They have expressed to me that if they can't find an issue(just my luck), or if they find the issue to be my fault(IE I put the phone too close to a credit card magnet or some dumb crap like that), then they will charge me not only for the parts and labor, but for the return shipping... and we all know that they'll charge me way more than the phone is worth.
I was just wondering if anyone else has had this problem, and if there's anyway to fix it without having to send my phone in to samsung? I have been told, also, that I could try reflashing the phone to it's original firmware and software, but I am afraid of screwing the phone up since I've never done anything like that before.
Thanks!

LG V10 just went into a boot loop

Last year I had the LG G4 phone which went into a boot loop. The phone rebooted while in use and would never come back on. I had it replaced but was given a refurbished phone. About a month later, in late January 2016, I was able to upgrade to the LG V10. I went with LG again even though I had the previous problems as I believed it was not something I'd run into again.
Unfortunately, that is not the case. Less than a year after purchasing my LG V10 it just went into a boot loop. Same exact situation... while using the phone the screen locked up, turned off, and now all I get is the LG startup screen which flashes off and back on every so often. I just chatted with Verizon and they confirmed this is a known issue with the LG V10.
So now in less than a year I am not only without a phone but also lost access to data on it. Thankfully this time I made regular backups of my phone in case this type of problem happened again. I'm sure Verizon will swap this phone with another refurbished device but this will be my last LG phone. My fault for trying to stick with them after the last problem. I won't make that mistake again.
According to Verizon they are familiar with this issue and claimed it was possibly related to a recent system update. My phone updated about a month ago but nothing else changed recently. I'll be back at Verizon in the morning to get them to process a replacement. Now the problem is I have a Google Pixel on order which I was going to trade-in this V10 for. I wonder what trouble this will cause now with that trade-in. The refurbished V10 I most likely will receive should still qualify for the trade-in but I'll have to see what Verizon says in the morning.

I have heard it's related to a hardware issue and not a software issue. However, the software IS seriously out of date.

I've just been through the bootloop/Verizon replacement situation also. They will send a refurb, it is unlikely it's a software issue however.
I was rooted on 5.1.1 v 11b when my V10 looped. So I had literally never updated my phone.
