I've got insurance for my cell phone through my credit card. If it breaks, they'll send me $250 to buy a new one. And my RAZR Maxx is definitely messed up.
The problem is, the problems are intermittent. And for me to make a successful claim, I have to get a technician to look at the phone and write a letter saying it's broken. I had to go through this process a couple of years ago with a Motorola Atrix that was clearly, obviously broken. And the technicians are always like, "what? what do you mean? what good is a letter like that going to do?" No matter how many times I try to explain to them. It's like they think I'm trying to trap them.
Anyway, is there anything short of throwing the phone off the top of my house that I can do to my phone that makes it easy to show to a technician and have him verify there are issues with it? I'd like not to destroy the phone in case my claim is denied. There are other criteria other than just proving phone is broken. And if the claim is denied, I may need to use the phone for a few more months till I can afford to buy a new one.
The phone is rooted. So I can install whatever software that needs the phone to be rooted. And I have asked in the past, rooting the phone does not cancel my insurance. The case is basically the cell phone insurance department doesn't seem very technologically savvy and don't have a lot of clauses you see when cell phone company's are describing cell phone warranties. Then they have other clauses that you would never see in a cell phone warranty.
If you want to know what's wrong with my phone, like occasionally, nothing it can do will it lock onto the GPS satellites, and I'm stuck somewhere trying to navigate my way to some place.. Occasionally it'll pop up on my screen saying "HDMI cable detected" and orient my screen sideways like if the phone were in a dock. It does this even though there's clearly no HDMI cable connected and I have turned HDMI detection off in the settings. Plus, the phone is just god awful slow a lot of times. Trying to use Chrome on the phone, a lot of times it'll hang and eventually I'll get the message "Chrome is not reponding", then I have options like do you want to wait for it, or go ahead and kill it.

Have you tried returning the phone to bone stock with a stock recovery image and rsd lite? Be fore warned, you will lose root but, you can get it back. Afterwards it will be like a new phone(faster, a lot less buggy and force closes) unless it is truly a hardware issue. I have a motorola xoom that started having serious issues, I went through the whole process, and it was like a completely new tablet when was done, battery life I hadn't seen in over a year, very responsive, it was like I had just unboxed it from the store.
Truthfully the technicians probably DO think you are trying to trap them when you are talking about intermittent problems. Intermittent problems are hard to diagnose with anything unless you can tell them a specific action or pattern of actions that leads up to the problem. I am sure they get a lot of people all the time with "it doesn't work right" claims to try to get money for a new phone.
IMHO it would be worth the shot to see if it legitimately has a goofy problem, or can be easily fixed at home.

Yeah, thanks Draxin. I've tried restoring to a factory image. And it seems to work okay for a couple of days before small things start back up. A couple of months later, the phone is as flaky as it ever was. It could just be software, that is possible. But it's not like I can go in and fix the software myself or anything. And I think hanging around the internet, looking for tweaks and fixes any more than I already have is really an unreasonable request by the insurance company.
What you say about an easily repeatable pattern, that's what I was hoping to figure out by posting here.
But getting no responses, I think I'm just gonna start my claim and when it gets to the point of proving it's broken, I'm just gonna microwave the phone. Googling all over the Internet that's the only advice people seem to offer.
Basically as it is now, I'm gonna have to pay for a new phone and hope this clumsy phone insurance through my credit card company makes good on my claim. I know I meet the criteria because I've read the policy. It's just the hoops they put you through to prove you meet the criteria that I'm worried about.

With a full wipe and stock motorola firmware? Or just a factory reset?
Either way wish you the best of luck
Yeah try using rsd to fully restore. I fixed a lot of my problems that way .

Very true. It is funny/sad. Spend some time on a site like this and it seems like everybody knows these things. Talk to your friend or the typical consumer of smartphones and it is foreign to them. They feed into the advertising that the newest and greatest will solve all their problems, not realizing they are falling into the same viscous circle. They will actually disbelieve you, cause... well come on, the phone is two years old! "The guy at my carriers store is surprised my phone still works. Sure he got the job two months ago, won't be there five from now and has no idea what a OTG cable is, or a independently powered usb hub but, still he works there.. so he must know what he is talking about! I am sure it has nothing to do with commission of sales!" (that was facetious, by the way)
I am curious how many people have thought that their smartphone was dying or to old because a factory reset didn't work(not talking about you lavender, I don't know what you have done to fix your device( guess I am semi-hijacking your thread)).
Motorola(or any device manufacturer for that matter) isn't going to tell the typical user that a firmware reflash is required to get a couple more years out of their device when they can sell a user (that won't waste the time to Google)another device. Certainly won't advertise it right next to their latest and greatest device. Really how many people outside of the power users or gamers REQUIRE a quad core processor with 1500-1800 mhz, or 2-3 gb of RAM. When typically, it will end up the same way in a years time, depending on how much they use it.
Porn doesn't require those specs!!!

Okay, so it's a bit of a long story but there's a woman I work with who had her virtually-new Samsung Galaxy S3 stolen by her recently-split husband last year. We all knew it was him, but we had virtually no evidence, other than it's disappearance. Anyway, so this woman recently was in his now-separated husband's flat & was rooting around. She found a Samsung Galaxy S3, smartly took a picture of the IMEI & left it. She knew it was hers, but wanted to be 100% sure. She went home, checked the box, & of course they did match. The next day, she went back to his house & manipulated the situation so that she could find enough time on her own to go take the phone back without him knowing. So she brings it into work with her the next day. The problem is, the phone now has a password lock on it. She then spent the night trying to guess the password, but to no success.
So, me being the tech guy that I am, she asked me to try to get into it. I said, the easiest way would be for me to wipe it & factory reset it, but that she would lose all of her information. She doesn't want me to do that. She wants to get pictures & stuff of her / their kids off the phone, as well as look into who her ex-husband had been talking to / see who knew about him stealing the phone. So, I said it should be possible. However, I'm not a hugely great phone guy. I'm good with computers, but not so much phones.
So, we spent the day trying various exploits found on Google or YouTube but to no success. There was one method where we had a little success where we turned the phone on > Emergency Call > Emergency Contact > Press Home > Press Power > Unlocked home screen in then meant to appear. It never did. Although we could get it to quickly flash whatever was on the home screen (which was a picture of her / their kids, which she'd set to the phone before it was taken).
So without any of those methods working, I'm tasked with now getting into the phone at home. I have no idea whether USB debugging is enabled, I would assume not. We are unable to reset the password via Google Recovery or anything because we're never offered the option. As I say, she doesn't want me to wipe the phone. But there has to be a way to get into it otherwise, either through brute force, or one of those other password cracking methods possibly?
There was a technique I found on Google at work, something about connecting the phone to your computer via USB then trying to do some stuff from command line or through a Linux distro, which I need to re-find & try.
But alas, does anyone here have any methods or know any ways that I could get around this password lock?
I have to say though, I'm glad it's not that simple (atleast it appears so, anyway) to get around one of these passwords. Makes me feel a little safer for my own Galaxy S3! haha
Hey
You said u tried the Google account method right?
If that's not working try to flash philz recovery and from that you can access the contents of the internal SD card..
U can also TRY to use the custom back up option offered by his recovery and then custom restore the data..
I can't assure you that it will work but you can try it..
Best of Luck

We did not try a Google account method, I don't think? Think we tried to log in to the ex-husband's Google account on my iPad for some reason (can't remember why now tbh) but we could not guess his password. He's apparently changed it since they split.
Won't flashing the phone wipe everything that's on it?
Hey
Not if your just flashing a recovery..
Just youtube for some videos on this...
I had see one some time back..

If he lets her into the house so easily then:
1- HE didn't steal the phone because he felt no need to hide it
2- The "woman" is invading the guy's privacy and checking personal info without consent
3- Seeing who he talked to is a typical behaviour pattern of someone who is invading someone's privacy for ill intentions
4- the "woman" can always request for the guy to share the kid's photos and other stuff. No need to snoop around
To the OP:
If you do help this person break into the phone and turns out it wasn't hers, then you are aiding in a possibly criminal activity.
If he did steal, then all the best to you. Otherwise; Beware of the LAW.

Like I said, if it was indeed stolen, then I wish the OP luck.
I'm just curious why the person never approached the police with proof of ownership instead of trying to bypass the security.

I can't remember the reason she believed the phone was stolen, to be honest. The reason she had access to his house, was because they have kids together. She had gone to go drop the kids off, or pick them up. For some bizarre reason, I don't know why, he left her in the house alone after he went to take them to school (telling her to lock the door when she leaves). She took that opportunity to look around the house for the phone, as he'd never previously admitted to taking it but she was sure he did.
She found the phone, took a picture of the IMEI, went home to match to the IMEI on her box & it saw that they were the same. She's shown me the picture as well. confirming that it was indeed her phone, she then went back to her ex's flat the next day (because he was going to come along to their daughter's birthday). Just as they were about to leave, she says she needs the toilet. So, she runs back upstairs & grabs the phone without him knowing.
I think the reason why she never went to the police about it is because he was trying to get citizenship to remain here in the country, & she didn't want something like this to jeopardize whether she's in a relationship with him or not; they do still have kids together. Sending him back to Kenya over a phone wouldn't do anyone any good.

Hi. I have a Kindle HDX 7" and its been great, I love it. It's running stock ROM and I've not tried to modify it in anyway. The guarantee expired last November. I've been taking it to college daily and last week it developed a problem. The touchscreen started playing up, sometimes it was frozen and didn't register any touches, other times it went haywire with lots of ghost touches. Maybe it wasn't ghost touches, maybe it was all the touches from before catching up if you see what I mean. Anyway, it was not good, very frustrating and not much use for anything.
I didn't particularly want to reset it since I had a lot of apps and documents but I didn't think I had much choice so I reset it via the settings but it didn't cure it, the problem persisted. So I contacted Amazon and asked if they could still fix it out of warranty. They said they don't fix Kindles, they just replace them, and the operator tried to sell me a new one.
So I took it to a local shop and the guy seemed to know all about it immediately. He said it was a virus and that he could replace the firmware for £10. I had my doubts. I'd heard that the bootloader was locked and that viruses on Linux variants were rare anyway. But I thought if there was a chance of success it was worth £10.
Its too early to say for sure but I think whatever he did may have sorted the problem. The thing is, I'm full of doubts now. Can anyone answer some questions for me? Is there such a thing as a hard reset? Is it different from resetting from Settings? Was I right about the bootloader being locked? And does this mean that it was highly unlikely that he replaced the firmware? Is it possible that it was a virus?
The last question is especially important to me because if it was a virus, then its highly likely that I got it at college .. so what's to stop it getting the same virus again? I certainly can't afford £10 every week to get my Kindle working again. I feel like such a dope, I should know the answers to these questions and if I'd been a little more patient perhaps I might have learnt something but I was emotionally devastated at the thought of losing my Kindle through ineptitude. Its still possible that it was a hardware fault, maybe an intermittent fault with the digitizer from being knocked about in my rucksack with my books and things. I don't know.
Any advice would be great.
T.I.A.
I'm currently working at a sandwich joint in Garden Grove, near my house, and there was this Samsung A51 phone that has been there for over 8 months now, apparently someone left it in the bathroom awhile back and never came back to claim it, so the manager challenged everyone to unlock it, whoever unlocks it, keeps it, simple ja? Well, it was a 3 x 3 dot lock, and there are over 200,000 answers to crack it, so he gave it to me because everyone gave up on attempting to unlock it. Upon bringing it home, I erased the entire data, in case I might unlock it and accidently stumble upon the previous owner's data. I then went around on Youtube on how to unlock it (since the original owner's Sprint SIM card is still on there, and his/her pin), and I got nothing. So now, I'm left with a clean phone with the previous owner's lock on it, and I'm trying to unlock it so I can clean off their data so I can claim it (Since I could use a new phone anyway), note, I've already did a hard reset on it, so there is no trace of the original owner's data on it except their pin and gmail on it. Is there anyway I can unlock it, and 100 percent clean it so I can claim it? Thanks

I'm not going to help you unlock that. Maybe someone else will? I'm not trying to give you a hard time, but here's my 2¢ about this.
Personally I wouldn't keep the phone, and I definitely wouldn't try activating it. If the original owner reported it stolen, then police will be knocking on your door within a few hours of trying to activate it. The honest thing to do, and what someone should've done 8 months ago, is turn the phone over to a Sprint store. They would've been able to contact the owner and get it back to them. The owner probably didn't come looking for it because they didn't remember that they left it there, or it was stolen from them. I also think it's really sh*tty to wipe someone else's device. Very important information or irreplaceable data could've been on it. Not everyone backs up their data on a regular basis. Again, I'm really not trying to give you a hard time. I understand why you did it, and I've been guilty of doing the same in my younger years. I just want you to know, there's much better ways to handle this kind of thing in the future.

Eaiser said than done. I'm gonna return it though, knowing the fact the police wouldn't knock on my door, considering the manager left it on for awhile and everyone attempting to unlock it already, now then, how do I explain to them I wiped out one of their phone's hard drive clean? I tell them I found it like that or sumthin?

Okay, one more thing before I actually give it to them, awhile back, I put on my gmail as an attempt to link it with the phone, and once I realized nothing can be done, I did a hard reset, any way my gmail is still linked to the phone, or its still clean without any traces of my info on it?

You should be fine.
I have an old AT&T Asus 9020A tablet. I got them new years ago thru my phone plan with AT&T. It wasn’t used much and is like new still.
Anyway, I take care of my mother and she likes games and painting by numbers on her iPad but she broke it and screwed up her charging port. I want to fix this tablet up for her.
I bet it wasn’t used 2 months and was just forgotten….I looked it up and completed a factory reset on it and wiped it clean. So I was trying to set it up and get her to painting again! It’s bout to kill her not having it..lol
I was setting it up and it wants the old email associated that was used to set it up. There is no way to remember that or even get it. I asked my daughter, she don’t remember. Anyway, are there any way I can use (reset) this tablet not knowing the old email that was associated with it? Where I can fix her up for her or am I just wasting my time? Any help would be greatly appreciated. Thanks in advance!
So it is FRP locked?

It’s not locked. It reset ever And started the initial setup as if it was new. It just wants the old gmail for some reason before it will accept the new one. It lets me start in the setting up her account on it but is asking for the old email for verification….. I don’t have it and there is no way to remember it unfortunately. I know they are there to keep folks from stealing them and that’s great. But 10 years later…LOL Is this possible?
what you describe (verify device with google account) is called FRP lock (factory reset protection). this is same on most/all official android devices to render device useless on theft.
however, the unofficial by-pass methods vary for each device model/android version. search on YouTube.
