[Q] Brand New Galaxy Nexus not loading/Logo boot-loop

Hey guys,, just got my new Galaxy Nexus, brand new one
Charged it to full as it said in the manual and turned in on, it got into the first 'setup' window and decided to crash, ever since it's boot-looping on the Google logo like in this video and won't do anything else.
I tried factory reset from recovery, I tried to remove battery and try again, I tried with and without SIM, same thing...
now my question is - did i get a faulty phone and i should replace it or it's something I can fix myself? Thank you

As long as there's no icon of a lock under the google logo in the first screen you see while booting, it's a production problem.
all options given to you by people around here about how to unlock it and try to fix it yourself are redicioulus in your case. When you have the phone for less than 7 or 14 days (depending on the country you life in, best way to check is by going over the shop receipt it should be mentioned all the way down. If you bought it online you got a mail) you can walk to the store and demand a new one. If they tell you that they send it to the factory point them on the law and the promises on their receipt... you have the right to give them the package back and pick a new one from the shelf with the same price.
But remember to take everything you bought (cables, earplugs, guide, the cardboard inside the box and the box itself) with you! If you don't they will tell you that you did not bring anything and have no right to pick a new one.
Just get a fresh one it's the best way for you since this problem emerged within the first few hours (and literally on it's first boot). It's most likely a production error. Waiting for a fix at the factory will cost you weeks... and many people report scratches on their screen and broken covers since the phones are not always treated nicely during their travel and fix.
Please post future news on your case here... it's a great help for people with the same problem.

Same problem but after months
Hi there,
I just had the exact same problem, with a difference : my phone had been working just fine for months. Now, impossible to get it to boot. It cycles the "Google" screen, and that's it. I found that when I hold the volume button down as I start the phone it shows "odin mode", but I do not know what it is for and it does not seem to download anything.
Any ideas?

When it happens right after you purchased the phone, it's better to bring it back to where you bought it from.
On the other hand, try this. Hope this helps.

What do i do now that HTC has screwed me over?

Just to give you a brief rundown of everything that's happened..
I'm 17 and saved up for a few months to buy a HTC One X. Needless to say, it's probably the most expensive phone i've ever owned, since all my other phones were hand-me-downs and old phones from eBay.
This morning i wake up and go to work as usual. Just to find my phone's display won't switch on. As you can imagine, I'm tirelessly panicking and try the 3 button combo.. to no avail.
Using Fastboot to reboot didn't work either.
This phone turned into a brick overnight, and i have no idea what happened??
Just before i left for work, i did check my phone and it was working alright.. Then five minutes later, it won't display anything.
The thing is, I can't take it back to HTC either because this is my 5th replacement phone!
First one had black glue smudged on the LCD it's self,
Second one had the screen not glued down and wasn't aligned,
Third one didn't even have any glue applied and the case wasn't even attached properly,
Forth one had this problem where the screen's LCD would dilate if i touched it - even lightly,
and this one is my 5th, the antenna wasn't properly connected and now the screen doesn't work.
I've had terrible luck, and i don't know what i can do?
If you can give me any information to get me out of this, it would be much appreciated.
Although i still can receive text's and calls fine, it's just the display..

Since you’re unlocked and running a non-stock kernel and ROM, maybe some of the dev-ish folks can help you resuscitate it if it’s indeed a s/w problem.
If it’s a h/w problem, what to do depends on where you bought the phone and how old it is. If it’s within the remorse/DOA period maybe you can exchange it. It’ll be hard for whoever you bought it from to see you’ve unlocked it if nothing’s showing on the display.
If it’s outside of the exchange period you’ll have to send it in for repair. If you can’t bring it back to life to flash it back to stock you’ll have to throw yourself on the mercy of HTC Asia in getting it fixed unlocked. HTC's different repair centers seem to all have different policies related to warranty coverage for h/w faults on unlocked phones. If it is a dead display maybe you’ll get lucky.
You might want to put a note in with it telling your “I’m 17” story and how devastated you are something you’ve worked so hard for has failed. Repair techs are people too. Good luck.

I shook the device out of frustration.. and it started working for a few seconds.
What's going on here? Is it a faulty display/connection? Is there a way to possibly just send it to a nearby phone shop and get it fixed?
Sorry about all the questions, I'm shocked, happy, and devastated all at the same time.

Are HTC refusing then? That seems a bit off/ illegal... Surely under the faulty goods act (I assume the law isn't THAT different in Australia to UK) they have to take it back as it CAN'T be a year old and they can't prove the issue was caused by your mistreatment. It doesn't matter how many phones you've had... Also, where did you buy the phone from? I think you should be able to return it through the shop as THEY sold you the phone, not HTC... They are still under an obligation as they sold you the thing.
Plus, the 'I'm a 17 year old and saved up for ages thing' might work too! I'd try not to get too technical with the law if you go down this route though!
Best of luck sorting this out. It's within your rights to get a replacement (you bought the phone new, I assume?) so I'm sure this will eventually work out. Don't give up! You just need to speak/ write to the right person...

What rom were you on?
I remember my One X not charging at all while it was turned off completely although it showed Orange charging led.
It could be that you ran out of battery and phone not turning on. Due to no charging effect.

@Op,
Reading your story there's one thing that's crossing my mind.
Could it be possible the battery run dry during the night?
It sounds stupid but those things you forget easy when you're in a hurry or stressed.
I don't read anything in your post you tried to charge.

Yes. But not in every region (yet). Do a search. It's been disucssed. Also, it appears Samsung's going down the same path.

Aware of the discussion... Using the xda app and didn't pick up that the phone's been 'HTCdev'd (my fault for not reading properly - sorry, folks!). Still not sure HTC/ Samsung can legally 'sign your rights away' though. Still, not a discussion for here...
Hope you got the phone sorted anyway.

Under Download Mode it says "Mode: Developer" if it's still a Developer Edition. The guy I got mine from had the same thing happen. The first time he sent it in they sent it back with retail firmware in it. He got back in touch with them, sent it back and the second time they got it right. But before it came back he switched to T-Mobile. He sold me his Verizon Note 4 Dev Ed. It's working like it's supposed to now.
They can do it right but you'll probably have to hassle them to get it done. Good luck. :fingers-crossed:

TO ALL OWNERS OF THE SAMSUNG NOTE 4 DEVELOPER EDITION (VERIZON)!
IF YOU HAVE DORKED UP YOUR PHONE - i.e. if you flashed the OTA with greater than version BOAF (or any version which took your developer phone and cooked it into a retail item), please read...
I just sent in my phone to Samsung, as I was one of "those" who accidentally whacked my Note 4 back to retail stone age!!
My phone is on it's way back, they overnighted the device.
Not only did they reflash my phone back to developer (gosh, would just love that ability to do that, yes!!), but my screen had burn-in and asked if they could replace the screen - I'd pay for it. They charge $237.01 to do it, BUT (BIG BUTT) the deemed it a manufacturer defect, and replaced it for no charge - NICE!
But, there are a few things to note: that's if you want to preserve the Note 4 for a while.
1. If you are stuck in retail mode, Samsung will fix it, at no charge. it takes a little less than two weeks to get it back to you.
a. Call 888 987-4375, follow the prompts, when you get to your first representative, ask them to pass you through to a service / support supervisor. Then, state you have a developer edition in which got put into retail mode (say it took an update) and you'd like it to be flashed back to developer - PLEASE NOTE: They will push it back to KitKat (ANJ5) "what the phone came with". They should not give you a hassle, they'd be glad to do it as a free service.
b. If there is another legit issue (like screen burn-in; in my case) they will diagnose it, and screen burn is typically covered, even out of warranty - pending any determination of additional abuse, but they will generally cover it. Additionally, any other defect that they may find, they will replace as...
c. Historically, my experience with Samsung is, even if the device, monitor, tv, computer etc is not functioning properly, even out of warranty they will repair it, again, pending any signs of abuse. this has been my experience - i.e. in 2003 I had a Samsung monitor which had a intermittent bug in it - even 2 years after the initial complaint and out of limited warranty, they had a new monitor in my hands next day, couldn't have been nicer too me, and I did not have to ask, they offered.
So, having said that - Though I think Samsung is completely dog-gone batty for doing up the Note 5 / S6 the way they did (sooooooo applesque) - they do stand behind their products.

Can someone take a picture of the download screen that shows its a developer edition. I'm having a hell if a time communications with plano repair. They are either playing dumb or they are dumb. Got phone back broken first time second time broken but locked. Now they are sending me emails saying phone checks out fine what is the problem. I need to show them what an unlocked boitliader looks like I think it im going to get a retail phone back again.

It's not too clear but maybe it'll be Ok.
Update: Did you follow the directions posted by @anticloud one post above my last post? Who is plano repair? The only people who have a prayer at knowing how to deal with a Dev Ed phone is Samsung Corporate Headquarters. And even there only a small handful of people who actually set up the Dev Ed phones are going to know what to do.

Severe brightness issue (screen largely unusable)

Hi all, I have a problem with my stock T-Mobile US S9. A few months ago this weird thing happened where if I turned on my screen immediately after it turned itself off, only the top few lines would be visible. The whole screen would take input, but you could only see a little below the status bar, maybe. If I waited a bit and then turned the screen on, it would work normally, with the whole screen visible and looking fine.
It's gotten progressively worse to the point where this happens most of the time I turn the screen on. However, I've found two workarounds:
1) My Always On Display is set to turn on when I tap the phone. If I do that, the AOD works as normal, and if I then turn on the phone screen the phone screen works fine. This only works when Always on display is set to turn on on tap. It does not work if AOD is set to always be on.
2) If, when my screen is glitching out I hold the screen up to a reeaally bright light (like inches from a lightbulb), the rest of the screen turns on. It's weirdly green tinted and kind of stuttery.
Turning off automatic brightness does not fix this issue. If tried booting in safe mode and even factory resetting the phone. Issue still persists, including on screens like when the phone enters recovery mode.
The fact that I can get the screen working normally using workaround #1 makes me think this is a software issue, but the fact that it happens on the recovery screen makes me think it's pretty low-level. Any ideas? Anyone else had a similar issue?

I gave Samsung tech support a call and the level 1 tech I spoke with seemed to think that it was a software issue and that I should bring it in to be looked at by a technician. I'm in Maine at the moment and there's no Samsung or UBreakIFix stores within two hours, so she suggested taking it to Best Buy to look at. Not amazingly helpful or surprising.
If it's a software issue though... I mean this is my fourth Android phone and I've rooted and flashed ROMs on all the previous phones anyway. I don't want to lose Samsung Pay, so I'd rather not unlock the bootloader, but is there a way to flash the stock operating system or something? The exact model number is SM-G960U

It's a firmware or hardware issue not software as a reload* would have fixed it.
The firmware has been corrupted (needs reflashed) or there's been a hardware failure.
Best to send it in for repair or take it the a Samsung Experience Center as they can reflash the stock rom and have advanced diagnostic tools.
*make sure all system apks are running on factory load and have not been updated after the reload.
Updates, destroyers of worlds...

If that’s really necessary I’ll do it. But the closest place is out of state and when I called them said it would take 4 hours just to do a diagnostic. That plus the round trip... if there’s a way I can save some time, I’d like to.
For example, if one possibility is a stock firmware reflash, that’s something I’ve never done before on a Samsung device, but not very different from things I feel comfortable doing. I've flashed roms and rooted many android devices in the past. From a preliminary search , it looks like there's even a leaked tool online to do so from Samsung called Odin and that I just need to find the latest SM-G960U image with the right "csc" code for my carrier (I think TMB for T Mobile US). What would be even better is if one of those diagnostic tools you mentioned leaked the same way that Odin did.
Any recommendations on either diagnostic software or firmware reflashing? Or would you strongly advise leaving that kind of thing alone? I would like to still use things like Samsung Pay at the end of all this.

If it's under warranty let Samsung deal with it. A good tech with experience is invaluable.
Rather then waste time the extra ride might end up being the easiest solution. You could also next or 2nd day it to the center and back, make sure it's insured and packaged well.

That makes complete sense for something under warranty, but unfortunately my phone isn't. The S9 is about three years old now, and the Samsung rep was quick to tell me that the device was no longer covered. It looks like a mail-in repair service would cost about $175, which I'm theoretically willing to pay, but not if I can just handle on my own for free.

In that case you have nothing to lose by reflashing it. Hopefully that gets it.
Otherwise it be hardware... probably a good chance this actually the cause.
The good news is the 9's are available for a couple hundred in good condition if need be.
I was considering getting the 9 as a second phone (have the 10+) as the 10+'s haven't come down much in price.
Samsung current lineup sucks.

Huh. Well, before reflashing, I tried something I found other people suggesting for a related problem: https://eu.community.samsung.com/t5...t-bars-black-screen-issue/td-p/1745470/page/7
It's an app called OLED Saver. It's not perfect, the screen still has an odd green tint to it unless I use one of the tricks I was describing above. But I no longer have the issue where most of the screen isn't visible.
I might try reflashing anyway, will post results if I do.

Yeah, no joy. Reflashed by downloading the latest firmware using Frija for SM-G960U with TMB as the CSC, and flashed using Odin v3.13.3. If anything the problem is slightly worse now, but OLED Saver still mostly seems to fix it. I guess it's just a hardware issue with a weird software workaround...

Same type of brightness problem here as you describe, on my new S9 (G960U) - - Model starqltesq - CSS XAA
The product is under guarantee, but as it is imported from Hongkong to France, I don't have accesss to the Samsung local representatives and have probably to send it back to Hongkong ...
I will keep you updated if I learn something about the problem and the solution ....

Wiping the cache partition stopped this happening for me for around 24 hours but it came back this morning. On the Note9 forums someone posted that setting animations to .5 in dev options fixes this. I will try it.

Disable animations instead. It wastes resources. Personally I like seeing a fast, snappy OS do it's thing with no middle man needed. Lol, you end up waiting for the animations rather than the OS.

I've heard of people flashing custom roms and that resolved the issue permenetly, but can't find anyone willing to give some real feedback. I posted a topic asking this question, but haven't gotten any replies..

Not very helpful, but a work around could be to use Screen Filter

Hey could you explain what exactly did you uninstall and how?
After uninstalling it wireless charing stopped working or what did you mean by cant charge the phone?
Did it fully resolve the green screen issue?

Some people noticed that problem after upgrade Android 9 to 10.
At this moment we have some facts:
1) OLED saver temporary solves problem
2) disconnect NFC module solves problem, some people on xda and on the yt confirm that
3) heating back cover using heat gun can help - I Discovered that some weeks ago
Interesting comment from the yt:
Sour Words
Sorry to say this, but green screen issue is a hardware fault not something an update can fix. One of the updates from Samsung is causing the CPU to over heat and in return permanently damaging the oled screen. Not only that but also compromising the battery as well. The only fix is the replacement of both the oled screen and battery. This repair is entirely the fault of Samsung due to a faulty update that over works the CPU capacity. Therefore my advice is for you to return your device back to Samsung and lodge an assessment request. They charge a small fee for the assessment, but the entire repair should be compensated by Samsung. Be firm and keep the pressure via emailing them to insist on Samsung covering the repair costs. My Note 9 is almost 3 years old when green screen issue happened. They fixed the entire thing free of charge. But I kept firm and didn't let them bully me into charging me for the repairs, which was their fault in the first place. I must admit, my phone despite its age, is in perfect condition. Not a scratch on it. Which I know contributed winning my argument for the repairs. So if you have psychical damage, I doubt you will have a chance. Good luck to all who will give this successful method a go.

Question Pixel 6 refurbish check

I'd like to know is there any possibility to check if pixel 6 phone is repaired/refurbished?! I've bought p6 pro today but can't make fingerprint to work (FOTO in attachment). I saw that other people have same problems when phone turns off by self (battery goes to 0% and buy) but after hard restart everything works again...not in my case. Seller told me that his wife used telephone for just few days and decided to stay on iPhone, but I'm start to thinking that I'm scammed; under display on small plastics antenna line I see just a little scratch so I'd like to ask is there a chances that screen is replaced. All other looks like 100% new phone.

Sounds like it may have been opened. During factory assembly it's very unlikely for this to happen.
It may actually be a mark from a plastic pick used to disassemble it and not a scratch.
The display is replaced as are internal components from the front I believe.

Since the OP states that he bought the phone used, it's more likely that the person previously in charge of keeping the phone, damaged it/scratched it. Plastic is ridiculously easy to scratch, even a grain of sand in your pocket can be enough.

If the phone was properly cleaned and re-packaged and not damaged, there is no way for you to find out if you received a refurbished phone (phone that was sent back by the original customer without damage, return window or something). At least not from a "software" perspective. You as a perceptive human can always try to see if there is dust residue, fingerprint signs or anything "physical" like that on the phone/inside the package, but there is not much more than can help you to decide that (except asking Google, you could hit them up with the phone IMEI and tell them that you bought it used and want to know if it ever got officially repaired/replaced, but I have no idea if Google would even bother giving you a decent answer).
Concerning repair (phone being opened by a repair technician to fix stuff inside) - other than physical markers (prying a phone open can cause damage to the chassie), there is not much that you can find out about that. There is no way to get the specific part IDs with software and even if that was possible, it wouldn't help your cause since Google would only use genuine original parts to repair a phone.
Concerning the "plastic under display" part, I do not follow here. What plastic under display? The display is not transparent, you can't see the phones interior through it. Can you make a photo of your observation?

Most likely the battery died resulting in the FP Sensor getting disabled. A Factory reset and/or full flash to latest image should always be done when buying a phone (especially when it's used). This will fix your issue also (using the flash.android.com tool) along with the calibration tool at the bottom of this page: pixelrepair.withgoogle.com/carrier_selection -- 99% a factory reset/wipe, flashing to the lastest build and using the fingerprint calibration tool will fix your issue. If not, you can get a replacement by telling google you did all of these things and they'll send you a phone (usually an advanced RMA if you show you've done everything previously mentioned).
The "Flash Tool" will update your Pixel to the latest Android version, along with an option to "Wipe" the device (make sure to hit the edit pencil and pick "Wipe Device" & "flash all partitions" ; if its a VZW model, updating in Android System in settings and factory reset in Recovery will be good enough, along with the calibration tool): flash.android.com/back-to-public
If it was refurbished by Google, you can put your IMEI# in the official Pixel Repair link below, and it will tell you some information (for example if its Unlocked, "Pristine or Refurbished" etc - it's a pretty great way to find out some info about a pixel (didn't know about it until recently). If the screen was replaced by UbreakiFixit for example, it probably won't show up as refurbished. it has to go through Google to probably be changed in the system, but I am just speculating.
Code:

@Proday Can you return it? That would be the way I'd go initially. You got sold a phone that is defective hopefully it was through either ebay or Swappa with some guarantees.

At first, thank you all for helping.
@Alekos Last night i did install last (Dec) update with adb fastboot; found it here on xda (because google pull it back from servers) but as i sad, problem is still here/same. From some reason repairmypixel with google doesnt work; I put telephone in right mode, google chrome finds it, but when I start procedure it goes and goes and ~5min later Telefon restarts by self and Im getting disconnect error/try again msg. Ill try this link now to see what happens with imei, thanks one more time.
@bobby janow I've got a bill brom google store, but im going back in my country in a few day and don't have enough time to "play" with warranty procedures
Btw I've made a Foto of "under display scratch" the best I could; for me it is out of mind that someone opened display on anthena line but who knows

There are two separate things being talked about. @Alekos said to go to https://store.google.com/repair and you might find out if it was refurbished or not (not necessarily). Should look similar the the following once you enter your IMEI in the site:

And then there is Official Google Pixel Update and Software Repair, which I suspect is what you're talking about didn't work for you, but please confirm. I know over the last two months, some others have occasionally checked Official Google Pixel Update and Software Repair and found that they hadn't updated it for the Pixel 6/Pro yet, so maybe that's still the case.

I've understand what he sad. Imei checked, results below...
And attach with pixelrepair that doesnt work (pop up blocker turned off)...
And I can try with Official Google Pixel Update and Software Repair, but I'm certain that it is the same as factory image installed with adb command, that I did (although I've put dec update not nov).

Thanks, are you using the OEM USB-C cable? At least half a dozen users in this section didn't have success getting their Pixel 6 Pro working using the factory image zip, but Official Google Pixel Update and Software Repair got their phone restored to stock and fixed their issue. It really seems to have been a lifesaver for some.

Yeah, I'm a little bit experienced
I'm going through this Official Google Pixel Update and Software Repair, see results soon. And I'm thinking that I know where is problem with pixelrepair.withpixel...didn't kill adb command; this flash tool tould me that i have to do first becouse adb is already in use...can be sam problem.

Ah! Hopefully, you'll have the solution soon.

So, I did all as @Alekos sad in another thread:
edit-- sorry, didn't realize you already posted separately. I commented to your post anyhow.
Did you figure this out yet? I would try wiping the phone, installing the latest build from the flash tool website (specifically this link: flash.android.com/back-to-public), on that page, edit the options for "Wipe" and "Flash all partitions". After it's done, run the Calibration tool (bottom of this page: pixelrepair.withgoogle.com/carrier_selection ) - this should work, if not my guess is there's a bigger issue.
Still same problem with fingerprint...now I'm certain that's the hardware problem; or screen is replaced or FP sensor is dead
Anyway, I want to thank you all 9ne more time, I've learned something new yesterday and today!!

That message is so familiar to me and i'm frightening of it
For the last month I've been in possession of 3 (three!) p6p. The 1st one was received from my carrier and it burned out while updating to December software being only 2 weeks old, no sign of life, dead while charging etc.
Google shipped another one stating it is Pristine which means Like New condition. It came in a refurbished white box, much smaller than the original one and there was a tiny dent - almost like yours but located on top of the screen. What is the most important - I was getting that message "Enrollment was not complete..." Flashing at flash.android.com did not solve anything but was successful. Google support representative advised to get into safe mode, try to configure fingerprint again and it didn't work as well. Calibration tool was not offered as an option at all.
Now it's on the way back to google. The 3rd one I'm owning now is a new phone with no issues so far.
So my advice is to return your faulty phone to the seller if you are still able to. Getting a replacement from Google is tricky as you may get another pristine p6p with the same or other issues. Or you are lucky and you will get a good one but it's a lottery anyway. So it's up to you.
Good luck!

@asdor I was with seller right now, he brings me my money back...end of (sad) story There are still good people!
