a very strange hard brick

Hi!
First of all i got AOKP + Franco kernel for 2w without any problem and I didn't change any option since last week.
This morning i rebooted it, it switched off and it didn't start again.
I cannot switch one my nexus again since then. I have always a black screen, also if I try to enter in download mode or in the recovery.
I tried to connect to my computer and smt times my laptop see a omap4400 (i'm not sure about the name) but after few second it disappears.
Tomorrow I'm going to the service center... But I have a big doubt:
What the hell happened this morning?
Thanks

Remove the battery for 5 minutes and try again.
If that doesn't work,
Follow this guide:
1. Download the zip file from http://forum.gsmhosting.com/vbb/f634...eeeee-1465412/, created by Legija
2. Extract zip to whatever location you're comfortable with (I used Android directory)
3. Open up Device Manager (Hold down Windows Key, press R, the type in devmgmt.msc and press OK)
4. Go to actions menu, select Add Legacy Hardware
5. Choose install manually, then have disk. Browse to where you extracted the zip, select the 'inf' file in usb_drv_windows
6. Choose OMAP, you'll get a popup if on Win 7, continue anyway (driver not signed)
7. Once completed with driver, pull battery out of phone, then plug it into USB
8. Double click omap4460_tuna_hs_pro.bat to start the process
9. Once completed, unplug from USB, put battery back in, and power-up!
10. Extra step - depending on what's been done, it may 'brick' again - suggest to do a restore or a wipe reinstall afterwards to be certain (mine bricked again next reboot)

I'm having the exact same problem. I saw my phone at maybe 10% battery in the AM, said screw it and let it die, woke up this morning and plugged the phone in and nothing. No LED light, black screen, completely unresponsive. I've tried every trick in the book, and the only one that seemed to work marginally even was using a different battery, which got my phone to boot to the encryption screen, but then shut off again. It did that twice, and now both batteries are useless.
I used Legija's program to try and bring some life back to my gnex, even though it's not the international version, just in hopes of getting some of my data back (I have already started the replacement process with Verizon since the phone was insured), but I got no luck there either.
It's extremely disappointing and annoying to me that this phone survived all sorts of ROM installations (I was also using AOKP on 4.1 if someone wants to start making connections), reformatting, tweaking, almost every setting on that phone was modified by me.
Not only that but almost any software or hardware problem I did run into I could solve in maybe an hour, but I let my charge run out and the phone just up and bricks itself? Now, that's just bull****... I would be very curious as to an explanation as to WHY on earth this would happen. Very confusing.
Not to hijack the thread, but my interest here is not restoring the phone to working condition but just seeing if I can pull my data off of it. I wouldn't even be posting here had I been able to have an SD card with my gnex, which I figured was unnecessary at the time I bought it since I knew the space on their was enough for me already, and the added branding of "Nexus" brand which had me under the impression it was maybe stable enough by itself. Not a mistake I'll make again..
Is it at all possible to get the data off of my phone at this point? At least partially? I believe encryption makes it impossible but I'm rather stubborn. Any help would be greatly appreciated..

So just to be clear... You've been able to get it to boot all the way up to the encryption screen, right? If so you should be able to get into fastboot (Holding down BOTH volume rockers and the power key.) From there you could relock/unlock the bootloader to do a full factory wipe which might solve your boot issue.
As far as the data loss from the wipe, you could then try this: http://forum.xda-developers.com/showthread.php?t=1994705

I was able to get it to the encryption screen with my old battery that had a little bit of charge left in it twice, but it shut itself down on me both times. So now both batteries are useless.. I took it to the Verizon store hoping they would maybe try one of their batteries, but they just called customer service and told me they're just going to replace it at this point.
I have a feeling the charging mechanism is somehow damaged, because when I did get it to the encryption screen I had it plugged into a wall outlet and it wasn't charging at all. So, I can't turn the phone on whatsoever anymore.. if I could turn it on I could solve this problem... but it simply refuses to boot. The closest I came to interfacing with it was the OMAP Flash script, which did work, but didn't fix the problem.
So maybe if I could get the phone working enough to use ADB with it I could get my data back, but not even that seems possible..

If the phone isn't charging then there's something wrong with the USB port. One way to test that would be to use a battery charger. Also, try a different cable. I've had issues with a few different cables that for whatever reason started to not fit properly in the phone.
If you're USB port has gone bad then you'll need to either A) Always use an external battery charger. B) Get a replacement. C) Fix it yourself (Good guide here: http://www.ifixit.com/Guide/Repairi...+LTE)+Micro+USB+Charge+Port+&+Main+Mic/9641/1 )

Boot Looped

Hello,
Today, while I was using my phone, it restarted itself and has been stuck at a boot loop almost entirely since then. It has successfully booted up 2-3 times but will usually restart itself within 30-45 seconds of booting and then will be stuck in a boot loop again. When it has started up its usually after it has been bootlooping for a while. I have an H811 , I'm rooted and using xTreme Rom v2.0. I have had occasional random reboots here and there before but the phone always booted right up again without any issues. I haven't done anything with root/recovery since early September.
I've tried doing a factory hard reset without any luck. My phone booted up after I tried the hard reset and it was like the reset didn't happen. I can't boot into TWRP. I can boot into download mode and I tried to reset using kdz. It got to 100% but the the phone restarts and is back in the boot loop (then the lg flash tool gets an error and force quits). I've tried removing my sd and sim cards, I've tried swapping to a different battery, I've tried leaving the battyer out and letting the phone cool down. Nothing is working. I have noticed that when the phone is going to boot up correctly the full LG animation plays. When the phone is going to boot loop I only get a static LG Powered by android image.
Since I tried and failed to reset to stock using kdz, the phone no longer boots up past the LG screen. I've redownloaded the kdz file and tried to reset again with the same results. When I have it in download mode Windows recognizes the phone but it says there's an issue with the MTP driver. I've reinstalled the drivers and I still get that the MTP function isn't working correctly.
Any suggestions?

Hey man u r just having my problem. There is a thread already for this http://forum.xda-developers.com/showthread.php?t=3233160

I am having the same issue. I have T-Mobile G4 that is NOT rooted. I bought it on release day. I too would get random reboots, particularly after the recent security update. I also noticed that the operating temperature was really high, a lot lately. I thought it was a rogue app (clean master). Anyway, I updated a few apps and installed a few watch faces. Suddenly, my phone was drained prematurely. Plugged it into a quick charge charger when all the fun begins. Early on it would boot to the home screen but would reboot a minute or two later. Then it stopped booting to home. On two occasions that I caught, it was starting up like a firmware update just installed with the "Android is starting 1 of 143 apps" type of line. After seeing that and still not getting to home, I figured I might as well factory reset it. Well I was amazed to discover that a factory reset yields the same boot loop. All I get is the LG logo.
Defeated. I go to my local TMo retailer where I bought the phone only to find out that I have to wait for delivery of a replacement. I'm in Jump btw. I did notice that when the phone will boot to home screen for whatever length of time, the LED would work. The LED does not work during a boot loop. My research on this issue uncovered an alarming trend on the Internet. No solution other than replacement. No cause has been identified either. Without proof, these are my top suspicions: Quick charge, 128G SD, apps moved to SD. My hunch is quick charge. All of my chargers are Qualcomm certified quick chargers. and I use them 95% of the time. I would hate to add LG to my list of boycotted Android vendors under Samsung.

Thanks. I'll try reposting this there. I did use CSE flash. Oddly enough it booted up once this morning for about a minute then got stuck and rebooted. Now its back in the boot loop.

Sounds like the boot loop issue is a decent sized one- quite a few others, from different variants, having all having a similar issue. For me I was walking with my phone checking facebook when it restarted and got stuck. I definitely notice the LED issue too. I'm not on jump but will likely go into T-Mobile today and see what they tell me.

Exactly what happened to me. now after CSE flash of KDZ, it won't start at all. just boot looping. also after hard reset.

Freezing at initial android set up?

I just got my brand new OP3, opened it and turned it on to start setting it up, it freezes inside the android set up and then restarts itself after a few seconds of being frozen.
Any solutions? I really don't want to return it, I find it a bit stupid it doesn't even work out of the box

Might be a dud. They happen. RMA it.

I don't own this phone, but this happened to me with a Nexus, I turned it off, was able to get into recovery mode with button combinations, then I factory reset, cleared cache, and rebooted, it was fine.
I hope you can give it a try

Tried doing the Factory reset thing, no luck. Talked to OP support and the guy told me to submit a ticket with my issues, and that a "level 2 technician" would help me.
So I got home and plugged it into my PC, turns out the phone doesn't freeze when plugged in via USB. But on the included charger, and without being plugged into anything, it freezes and reboots itself in a continuous loop.

Keep us informed I'd like to hear what the problem/solution is

Hello, i have the same issue, did u find the solution ?

I also had my Oneplus 3 in a bootloop and freezing while showing either the 1+ square or the rotating red dots.
After I tried to get it repaired by talking with support and had been using my old phone for a few days and reflashing the ROM and recovery many times. I got it working again (ish) now it only freezes ones a day.
Support is a pain, I'm waiting for a level 2 techician for almost a week now.
So I any of you know a solution or have a confirmation that it is a hardware failure, I think we all would like to hear about it.

HELP!! S20 Ultra stuck in boot loop during REGULAR USE, Wont go in Recovery Mode!!

Hello all,
I need some serious help here. I was using my Samsung Galaxy S20 Ultra when DURING USAGE, the phone decided to reboot. It is rare but it happens. But the problem escalated when it refused to reboot again. It has constantly been in a boot loop ever since. It did fully RESTART TWICE in the middle but before I could unlock the phone it slipped back into its boot loop coma.
Everything on the phone is stock, updated to the latest versions for all I know. No combination of power and volume buttons help. What it only does it switch it from boot loops to a static boot screen.
ANY HELP OR EXPLAINATION WILL BE APPRECIATED !!
Sincerely,
SRV

These phones should never spontaneously reboot. That indicates a potentially severe problem; always take any sign of system instability seriously. Often it's the only warning you get before a boot loop.
You need to get into safe mode or the boot menu to do a factory reset. Make sure you're using the proper sequence and timing matters. Try holding the power button down for at least 30 seconds.
Poorly written apps can do this. It may be the firmware was corrupted (possibly a single event upset) or a hardware failure. Play with it...

@blackhawk
I have tried:
power button hold for long
power button + volume up
power button + volume down
all three
The current situation is:
It is stuck on boot screen for 5~10 random minutes then starts cycling again. What do you figure could be the reason for it to have fully restarted (then gone back bootlooping) when the situation was fresh ?
Do you think i should let it drain out ? (How long would it take lol)
Perhaps try unplugging the battery/ removing SD card WHILE its still booting ?

Don't know, not normal behavior. Maybe someone else has seen this before.
Try pulling the SD card* and sim card.
Try hooking up to the PC. Let it drain out ie hard reboot. Anything to break the cycle.
*it's backed up, right?

My S20U had the exact same issue last year. I had to send it in for repair and they replaced the motherboard.

I let it drain to zero, it calmly powers off and saves a tiny amount of battery just to display the 0% battery image when I try to turn it on. The the moment I plug it back in, bootloop.
Though I'm sure you mean let it drain dead zero, I've left it to do that.

The last really good flagship Samsung made was the N10+ snap. Everything that followed has had hardware issues, mostly the displays. The only way you know there are issues though is when people post about them on forums. Who knows what the actual number is? Only Samsung and those wimps won't owe up to it.
It may still be a firmware issue and not hardware.
If it is hardware it may be an issue with a ribbon cable or other module, and not the mobo. A Samsung Experience center at Best buy may be able to help and reflash it. Don't give up quit yet.
Yes drain it until it won't try to boot and the battery auto shuts down. You probably saw a "robound" effect where the battery recovered enough to have enough power to boot.
If it needs a mobo consider the repair price vs the price of a new (still available) or used N975U1/N975U. In my opinion this is a better Note in spite of some of the missing features. Just a rock solid work horse that's form factor is superb, well balanced with perhaps the best display in terms of color/gamma accuracy and calibration. I have two of them... no regrets. They are a joy to use.
The 3 yo one has over 8k hours on it and it looks, feels and runs like new, zero display degradation.
Only repair has been a battery replacement. A new one will be loaded with Android 10 which I prefer over 11/12. Pie though is still my favorite and the oldest one is still running on Pie.
I'm not pleased with Samsung's flagships since the N10+... Samsung just keeps dropping balls and lives on hype rather than solid performance.
Sammy, you suck elephant balls bad now.

My wife and I also experienced a similar issue with our S20 Ultra 5G. Except ours was an update that literally just killed the device. We tried every combination of buttons to get into recovery or bootloader mode with no success. Ultimately we had to send the device to a Samsung service center to have the LCD, battery and motherboard switched out.

Thanks for your inputs...
I let the battery drain condiderably, then with that low battery, I just pressed power button. Voila, recovery screen.
I have wiped the cache partition and am waiting for it to reboot (which the command line the screen says)
Does it say "rebooting..." for a long time or am I screwed further ?

Go for safe mode at the most. Normal mode will likely loop you again.
If you don't need to recover data> factory reset most rikky tik. Clearing the cache for this won't do squat.
The user data partition is corrupted at the least. If a factory reset clears the boot loop, be careful what you reload... or you'll be doing this again.
This is assuming the loop was caused by a 3rd party app or malware. A definite possibility.
Remember if you encrypted the SD card a factory reset will wipe that key and your access.

I am dead sure it is Malware.
I got it up and running and looping a few times now. The battery draining probably cleared some flags that prevented a normal reboot.
Phone has survived a minute in safe mode. Let's see

Negative. Keep the playing field level. An update now could brick it.
Factory reset if you can. No known rootkits can worm out of the user data partition on Android 9 or higher. A factory reset will purge it if that's the cause. Kill the intruder.
Delete your Samsung and especially Google accounts in settings first if possible. Reset your Google account password after you factory reset, write it down. If it was malware try to figure out when, where and how it breached the device. Any odd behavior that signaled the event.

If not try to get into boot menu again. Factory reset. Otherwise it will need to be reflashed.

As long as you flash the correct stock rom. Make sure it's the right one!!!
Not sure about the best method. Make sure you find out what is the best shot as you could hard brick the phone if you goof this up.
Throw it to Samsung if in doubt.
I've been fortunate and never had to do this. One reason I leave the Android firmware alone, avoiding even upgrades and updates. Android firmware flashing is the most complicated I've seen. A PC bios or a Canon Pro shooter, router are a snap to do by comparison.

It downloaded everything, rebooted and started installing the update. Reached 30% then slipped to bootlooping vigorously. To get to the boot menu I would have to discharge the phone again. Because of the installation process, do you think draining the battery could brick the phone ? I could leave it to discharge if this is not a risk and 30% will be rolled back.
Do advise.

You should never interrupt when it's flashing. Yeah it could definitely at least soft brick it.

Display randomly stopped working and I’m screwed.

Hello there fellow M51 users. I’ve been using the M51 ever since it launched. all was good, until last month, the display just stopped working. Took it to Samsung service centre, and they said it was the display. Kinda frustrating how it just stopped working despite having no physical damages. Anyways, I set out to find an aftermarket display as replacement, as the original one from samsung costs wayy more than the phone’s current resale value. After installing the 3rd party display, the phone turned on (in safe mode?) and then turned off a few seconds after I got into the home screen. This kept on happening as i tried restarting. I also noticed the phone get unusually hot. Now a dialogue box saying “Serious software issue detected” pops up while booting with a “Check for updates” prompt. I believe it is updated to the latest version. Is there any way over this? The technician suggests we do a factory reset, but I have 5 years worth of valuable data in there. Can I at least be able to retrieve the data? Should i try using an original display, would that solve this? Technicians locally are unbothered and lazy to help, so I hope someone can help me from here. Thanks a lot in advance.

Welcome to XDA.
If it will boot into safe mode you can get the data.
If you get into safe mode don't power it down, grab the data. Go into safe mode, if it crashes in safe mode you got big problems...
In the future redundantly backup all critical data otherwise sooner or latter you will likely lose it.
If you have expandable storage always use it as a data drive; all critical goes here, don't encrypt it, and then backup the SD card data on a regular basis. Many time if the OS or phone crashes/burns the SD card and its data are still intact.

I have a 3rd party display in my M51, it is LCD, you can take it the guy who fixed it and he'll have a solution. My phone works fine except sometime when i use a "amoled specific feature" the display goes blank and i need to hard reboot.
