[Q] Had my GN died?

I was updating some apps in the market, as suddenly the phone reboots without any warnings.
OK, **** happens i thought and let it boot. But now the phone starts the ROMs boot animation for about 4-5 seconds and then reboots over and over again.
I pulled the battery and started into recovery. I made a nandroid and wiped cache and dalvik. Reboot with same behavior.
Recovery again: wiped everything and flashed a new AOKP M3 - result: reboot and loop again
Back to recovery: tried to flash the before made nandroid - MD5 checksum error
Flashed an older nandroid and got boot loops again.
So, i think this piece is for the service now...
What is the best way to reset this GN? Using ToolKit to put back stock recovery and lock the bootloader? Or should i try something else?
Update:
Flashed Stock Google Image via ToolKit 5.4 and after that the phone is booting normal?!?
I reflashed the touch recovery and pushed the AOKP build 27 back to the phone and flashed it.
So far so good - I have to start from the bottom now, because flashing the stock rom wiped the whole phone and EVERYTHING on sdcard is gone
Do you think there is a hardware failure? Perhaps some sort of memory malfunktion or something like that?

Same thing just happened to me, thi is the second time

Firstly when you get bootloops or any other problem do NOT do a nandroid as it backs up EVERYTHING, including the problem.
When you "wiped everything" did you go to mounts and storage and format system, cache and data?
If not then you didn't do a proper full wipe.

This is my own experience, but I want to warn you guys. I had a similar problem with my GNex. The first time it happened, my phone rebooted itself every 5 seconds. I completely restored it using factory image and it ran fine for 3 weeks, then one day, the phone just rebooted itself and got stuck at the boot image. I had to factory reset it again to make it work.
After the second time, I called Samsung and sent it in for repair last week. They are shipping me a replacement unit. It seems the problem was hardware related.

For 3 weeks... exactly 3 weeks, 21 days?
I can tell you that my first boot loop brick was 20 days after I bought the phone. The second was later that day. But the third one was... again, 20 days after the last successful restore. Is there something magical about the 3-week mark???
I am currently taking nightly nandroid backups, so when I had my third boot loop brick my backup was just under a day old. If this is ultimately a hardware problem that can be warrantied, I guess I'll have to try that next time. I would have to make sure I return it with the bootloader locked, stock recovery, but without the wipe because it has to still be boot looping to prove there's an issue!
Anyway, things I will point out:
- It's the complete wipe in bootloader that blanks the internal storage.
- If you have CWM installed, you can back up the internal storage over USB via adb pull /sdcard/ ./sdcard/ (correct me if I got the syntax wrong)
- When the boot loop brick has happened, CWM is not capable of properly reformatting or restoring to the data partition. I have not found a way to repair it without blanking /sdcard (which on the GN is actually in /data/media), so if you don't want to lose those files the only way to keep them is to pipe them out, blank the phone, and then pipe them back in afterwards.
- After a complete wipe in bootloader (either by flashing userdata.img or by relocking/unlocking bootloader), you must boot the phone once into the OS in order to complete the reformatting of /data. If you try booting straight into recovery after a wipe in the bootloader, CWM cannot read or write from that partition.

Can't say for sure whether it's exactly 21 days but it's definitely around 3 weeks. Why don't u give Samsung a call? The phone is not supposed to behave this way. Plenty of people don't have this problem. My wild guess is that the internal flash memory is faulty.

I'll warranty it through my carrier next time as they do exchanges on site. The trouble is, once I've recovered the phone, there's no evidence of the problem anymore. The best way to prove it is to show it fritzing out.

I think this is a known problem. You shouldn't have to prove it to them. They should be aware of it.

It bricked again today so I warrantied it in-store at my carrier. They gave me a brand new one after being unable to find a solution when fiddling with it. As a bonus, all the little hairline scratches on my screen are gone too
The store guy said he's never seen this issue, and it's one of only two warranty locations for my carrier in the Vancouver area. So I can only hope this was a rare hardware problem and not something that pervades every GN they're going to sell.
I can tell this one is from a different batch because it came preloaded with 4.0.2.

Good for you. hopefully my new phone will behave

[Q] Unbootable green and red pixelated screen on boot and CWM6/5 load

So just to state the lead up to the unbootable phone.
Condensed version:
Flashed to Bio360 (ONLY working rom that was running for me thus far)
After a week of use, phone would boot for 5 seconds until screen turned pixelated
reflashed but did nothing
flashed to ICS using download mode again and worked but with limited function as when I first flashed ICS before Bio360
flashed using CWM6 back to Bio360 but still same problem
now will not boot into CWM6 and gets the pixelated screen either way
WILL go into download mode so I tried a few more ROMs to hopefully write over whatever issue there is with the software but nothing
reflashed using ODIN the CWM to 5 and 6 but same problem (will not load to CWM at all now
tried a few more times in the precise order as the first time I ever got the phone working with Bio360 (STILL a messaged up screen)
More detailed account of things:
I originally tried updating to the ICS upgrade a few weeks ago but got stuck on the boot screen and other issues. I finally flashed the CWM6 and updated the rom via that to the Bio360 rom. I finally had a working phone again after countless hours of trying to get it working. I locked my screen after timeout to a pin number but actually found it was a pain in the behind so tried to switch back. However I used the 'settings' feature which was present on the home screen after boot that comes with the Bio360. Then I deleted the icon an could no longer find the one that I was originally using, but found the other newer icon in the applications. So I took the lock feature off. Though it did nothing and the phone still required the pin. I tried changing it etc etc etc and nothing worked.
So, I flashed the Bio360 rom again and tried to start fresh, only to find that most of the settings that I originally were using before the re-flash were still present. This lead me to believe the settings are not completely wiped and flashing through CWM6 does not do a pristine clean update. Then I read that I should have to clear any and all settings by factory reset, clear cache, partition or whatever other clear functions I found within CWM6. So I did that and everything was back in good order again.
That is until I woke up 3 days ago and found my phone 'bricked'. Not literally as I am told it is almost impossible to brick one of these. Upon rebooting the phone I found that it was booting to the Samsung logo and after about 5 seconds, the screen becomes pixelated with red and green colours, sometimes lines all over. The longer I leave it, the more the screen becomes a wash out.
So I tried flashing the rom again using CWM6 hoping this would fix, but the same thing occured. So I tried to use CWM5 hoping that would fix it but still the same. I tried flashing back to gingerbread, then ICS, then Bio360 as I originally did to get the phone working with Bio360 but the only thing that I can do now is boot into download mode. Anything else causes the screen to become pixelated and wil not boot past the messed up screen no matter how long I leave it.
I searched for other threads but only found threads based on a single large pixel or a physically damaged screen. However, the screen is still functional as when I boot to download mode or just before the screen becomes pixelated, everything looks great. Plus there was one time when I flashed to ICS I got into the blank screen with limited functional capacity as when I first flashed ICS and the pixelated screen disappeared. So this leads me to believe this is a software issue.
I believe that there is an issue with files being left behind that are corrupted or something similar but I cannot even boot to CWM in order to clear everything possible.
ANY IDEAS? I have explored every option that my limited understanding of software could.

picture of what it looks like
This is a crappy picture from my old phone of something like what it looks like.
https://plus.google.com/photos/111944628817208100010/albums/5793637254528885841
This is a capture after it was turned off even and I plugged it into my computer, displaying the battery charging animation, though turned pixelated after a few seconds.

My gut says hardware damage, like something inside the Tegra itself is fried, ESPECIALLY since it's happening sometimes while still in the bootloader (charging animation).
Try Kies emergency recovery. If it flashes successfully but still won't boot, or glitches out like this during the flash, you'll have to start the RMA process.

I am unsure if it would be a hardware issue though since the screen is fine during the 'download mode' and did boot into the stock recovery after a flash a while back, then flipped back to not getting past the Samsung logo and pixelating again.
Would I be able to load the download mode portion of the phone if it was a hardware issue?
I ask because my gut says the opposite.

flashing CWM 6 causes my phone to be unbootable and pixelated screen
So, I have tried to update the phone into whatever other ROM that I can possibly get working only to find out that after flashing a ROM that flashes the original recovery program included with Android, voilà! The phone works again and boots into the black screen with pull down menu. Back to square one for me.
Why would CWM6 be causing such a thing?

I'm on CWMR6 since the begining without any issue. Did you flash the touch or the non touch version ? Also whcih odin version are you using, maybe that makes a difference. The 1.82 and 1.85 are tested to be working fine with both cwmr 5 and 6. Also by reading your thread is seems you've never been able to flash through ICS one click, if possible try doing that.

I have been using the cwm5/6 touch and non touch. I have tried flashing them both. I have been using the most suggested version of ODIN 1.85 to flash. I do not think that it would make a difference as to which ODIN version I use, but then again I am quite ignorant on software.
The first thing that I did was tried the flashing using the one click method. I could only get to a black screen with the pull down menu containing the turn wifi on/off etc. I read that the problem may be permissions but I have tried that using the CWM when it worked and I was still stuck at the black screen with pull down menu. Without CWM I have no way of doing anything really since everything is in zip form and without CWM you cant use the zips.

Well then probably a logcat output to a developer would help understand the problem you're facing. Find some knowledgeable developer who can help you read the logcat and find the issue. Or post it here and maybe somebody would give you a clue.

I have the same problem, i bought mine in ebay, (i live outside USA so i cant get money back) my problem start when i try to install a apk, then, i try to restore with wipe in cwm (sometimes works, sometimes no) and eventually, only download mode work. I dont know what i do, but in one of my trys, ICS 4.04 works everything, but i was network lock,i try to downgrade to Gingerbread and the problem come back, i dont know what to do, i feel like i waste te money.
PD: I have the roger version
EDIT: I just flashed ICS from ATT And works, but i w ould like to root and i cant, every time that i flash CWM, the problem come back
EDIT 2: I use the one click to install ICS from att and works, its seem the problem is when i use a custom rom or the CWM, dont know why, its seems that is not hardware because ICS works perfect, but Every custom rom or CWM, cause the problem
Maybe is there a way torecreate all the internal partition, i dont know, or something like that, to make a clean install, I am starting to regret for buying this phone, maybe the problem is because is from rogers (a security rule maybe?)
Sorry for my english

I dont Know, its happen similar to me, but if i use ICS from ATT, everything works right
---------- Post added at 03:05 AM ---------- Previous post was at 02:45 AM ----------
Ok, i learned something, when a flash the Gingerbread version, there is a error while booting (the first time that boot lik recovery) , the error is can't access to /system/csc/ATT/system/
When i use the ICS from ATT, that doesnt happen, maybe that is the problem? i dont know, maybe someone can tell us what are these files

There is a working solution, http://forum.xda-developers.com/showthread.php?t=1953672 thanks to Rawr0w0,its works when you flash in that order, my phone is rooted and full working in ICS, i hope that helps you

problems installing roms - no carrier

So I've had this problem, and I fought with it for one night until I got it working. I'm sharing my experience here in case others have this issue, and I invite people that have encountered this issue to criticize the way I fixed my problems so that we can get the minimum bricked to working procedure and identify issues in loading custom roms.
The problem is that the phone after flashing a custom rom will work, but you get 'no carrier' meaning that the radio on the device isn't connecting to your carrier. In my case, 'Sprint'. I don't know why this happens, but no matter what I did, I couldn't get it to connect.
What I had to do was go back to stock. The MD4 stock didn't work for me, it would display the samsung note 2 branding screen, then the screen would fuzz out like an old tv that lost the vsync signal, and then the red light would blink blink blink. I bricked my pho.ne
The good news is, I didn't completely brick it. What you have to do is ODIN the phone. The problem was, it would never go into odin mode, it would always crash before it got there. What I had to do was take the battery out and power it ONLY via USB. Then it would go into odin, and I was able to flash the LJC firmware. It seems that if you want to replace the radio, you have to flash an entire rom to do it. Those downloads are a gig!
So even after doing this, it wouldn't quite work right. If you still have issues, you may have to ODIN a new BOOT image. Once you do that, then when it boots you'll get the standard sprint logo and animation / sound, but it will still hang. What you have to do then is load a custom recovery (odin), boot into that recovery, and format system twice then cache twice. The recovery that worked best for me was ClockworkMod Recovery v6.0.4.3.
That seemed to reset the radio/carrier and then I could load the original LJC rom & radio. I verified that I could access everything. Then, I did CF Auto-Root, and loaded a new custom rom. All was working afer that!

[Soft-Brick] Stuck at boot screen

Hi guys,
(Samsung S4 Mini GT-i9190)
I could really use some help.
I have been searching all over and perhaps I'm not understanding what is being said so if it sounds familiar and there is a solution then i'm thankful.
So about a week ago, the phone came back from repairs and had the motherboard replaced after the phone was washed by accident. Nonetheless, there hasn't been any hardware defects besides signal loss now and then.
When the phone came back, it had 4.2.2 and it automatically picked up the update to 4.4.2 which I did. The phone worked fine until 2 days ago, where it just stuck at the Samsung galaxy gt-i9190 screen and just freezes there.
I can boot into a custom recovery (Philz) (not stock recovery for some reason) and download mode. I then attempted to install CM 11.0 as I got frustrated. It worked, booted past animated logo and install the apps until i came to the language section where the touchscreen which didn't work (unresponsive). I then reverted back to the stock ROM found at sammobile (i9190xxxCOD2XFA - South Africa), loaded the custom recovery and still no booting past the first screen. The custom recovery touchscreen (Philz) is also non responsive (besides using the volume keys, home button and power for navigation).
I flashed a couple of times, nothing works.
Is there a root cause to these issues? The unresponsive screen, not booting properly?
Some info: KNOX is voided 0x1
Please help!! Thank you in advance

It's not „root“ that cause your problem. You should have to choose right recovery for your model. Flash back to original ROM and look for one of fully supported custom ROM here on the XDA and fallow all steps how to flash it properly. Succes ! Cheers !

Alright, I'll try that. What I did in the meantime was flash, Slimkat 4.4.4 UNOFFICIAL rom for I9190 (http://forum.xda-developers.com/showthread.php?t=2708677).
The rom booted into the andoird system but the touchscreen is still unresponsive.
@Boombastical .. If you can help me by giving me a guide in order to do what you say, then please do help. Even in recovery especially TWRP the touchscreen is unresponsive except for ClockWorkMod and Philz. So i don't know if it is hardware related or I'm doing something wrong.
Its driving me crazy :crying:

Update
So what I did last night:
I loaded the SlimKat rom and based on the stock bootloader and after doing a couple of battery pulls the screen starting functioning properly. However it was just luck or could've been something more technical.
I need help in understanding why that happened.
Then I decided I dont trust my method and reloaded the stock 4.4.2 firmware from sammobile. What then happened, is that it booted past the "Galaxy GT-I9190" screen into the samsung logo and then installed the applications. Come to the choose language screen, the touchscreen became once again unresponsive.
Bear in mind, that when I did a reboot with the stock rom, it didn't want to boot past the screen and just hung there.
So what could my problem be?
Is it the rom that I used? Using Unified Android Tool, I saw my region code is GB which I haven't seen anywhere in the stock roms.
Could the system somehow become corrupted? Emmc, partitions? Could the screen calibration be out of sync?
Must the bootloader always be the stock one? Are there custom bootloaders that one can use?
Please help, thanks

Possible solution:
So I thought it could be screen calibration so this is what I did to make my phone work.
I loaded the CARBON Rom as I somehow lost root privileges with SlimKat. It loaded into the OS as per normal but the touch screen didn't work. So after numerous battery pulls, i read this post http://forum.xda-developers.com/showthread.php?t=2353972&page=1 .
So then I connected the phone to the pc (having had the samsung drivers installed as well as adb) and booted into cmd promt as admin.
This is what I did in cmd prompt:
cd adb
adb shell (make sure there is a "#" as that ensures you that your phone is rooted)
echo 0 > /sys/class/sensors/proximity_sensor/prox_cal (did this several times)
echo 1 > /sys/class/sensors/proximity_sensor/prox_cal (did this several times)
@xcxa23
It then still didn't work (the touch screen) then somewhere on one of the pages in the above post, someone mentioned holding home button. I switched the phone off, I then held the home button (until it booted into the OS) and then powered the phone on. The phone booted into the OS and presto the screen worked again. I did a reboot and the screen is still fine.
Again I'm not sure if its that exact method but what I am sure of, is that I did a clean rom install (an option in Philz touch recovery), wiped the cache, formatted the options (boot, system, cache, preload, data) in mounts and storage and then proceeded to install the rom from the sd card.
I haven't tried with the stock rom as yet so if this helps you, goodluck and if you can help improve on this method or help me understand why this is happening, it would also be appreciated.
Thanks

Confirmed for that is

Hey guys, just a quick update.
I reloaded Cyanogenmod mod CM13. I can confirm that my screen didn't freeze up and booted perfectly. I also then decided to take a chance adn reload the stock rom 4.4.2 and it also worked perfectly and booted directly into the OS.
I'm guessing the screen calibration was out.
So if this happens to you, I would suggest loading a custom rom and doing the screen calibration reset through adb and then test again with another custom rom. Once you comfortable, you can reload a stock rom.
I used Philz Touch for recovery
Thanks to everyone who put posts up .. Time to rest

Not working again!!
Hey,
So in my previous post I said I got it to work. Well I did, up until a few minutes ago when the phone just decided to freeze up again. I restarted the phone and would you know, back to square one!
I've noticed issues that I'm wondering if they could be the problem:
1) The audio didn't work at all. By audio, I mean the mic. When I did voice recording, it just gave static, whatsapp calls, the other person can't hear you as well as regular phone calls.
2) I just rooted the phone in order to change the audio_policy.cnf and delete lines relating to the above audio problem but then the screen, return, and menu button didn't function. The screen could still rotate until I pressed the power button to lock then unlock and then it didn't unlock :crying:
So once again, some help guys please. Is it rom related, hardware (motherboard, chip) or software that just isn't working right? Could it be KNOX?
Thanks

Stuck on google logo boot screen after twrp recovery & then factory reset

Hi guys, bit of a saga here so bear with me...and also it should be mentioned I have little experience/understanding of tech stuff, so that isn't helpful either lol
I've had a Nexus 5x running 7.1.2 for not quite a week; it came with an unlocked bootloader (strangely). Tried to do the usual install twrp & root as I've done with previous phones (all pre-nougat) but all attempts failed. Couldn't boot into stock recovery from the bootloader at all, it would just boot into the system. OK, next thought was that an OTA upgrade to Oreo might work to restore a recovery - but got the BLOD (naturally lol). I found a fix in a modded 4-core Twrp 3.2.1 -0 fbe img + workaround injector zip from osm0sis & XCnathan32 which by some miracle worked.
So far, so good. Ffwd a few days and google play store keeps crashing on opening; I had the feeling that some glitch happened while it was updating, so I tried all the usual fixes like app cache/data wipes and uninstall updates/renistall google play, delete google account etc which failed. Next I tried a cache & data device wipe through twrp - also unsuccessful. Finally, I thought the only thing left to try would be to restore a backup I made on twrp - this led to the current issue of not booting, stuck on the google logo screen. I even thought what the hell! and attempted a factory reset with twrp - same result, where I am now. Google logo screen, however I still have an unlocked bootloader.
Would anyone be able to suggest where I might go from here? I'm pretty sure the version is N2G48C, if that helps.
Any suggestions very much appreciated...wouldn't mind getting to the 1 week mark with a functioning phone lol

Saga #2
Still no idea what's going on. I realised that I'd backed up and recovered the system and vendor .img files, which according to this thread would be a cause of the issue https://forum.xda-developers.com/nexus-6p/help/stuck-google-logo-twrp-backup-restore-t3320840/page3
So I made another backup without those images, did a full wipe and restored it - still does not boot, still only sitting on the google logo. Tried next to open a cmd terminal to see if I could reflash a stock image, but adb could not connect (maybe because the phone would have been on charging and not file transfer mode?)
Last resort as I saw it was to try the NRT, and see if it would flash stock via the bootloop/softbrick option. Process seemed to be OK, judging by the log - but it did not reboot to the system. Now there is a looping bootloop between the google logo and the unlocked bootloader warning.
Following wugfresh's instructions to factory reset from the recovery (the phone won't turn off via the power button so I just booted straight into the bootloader) Looked for the recovery option, selected....and nothing!!
So there isn't a stock recovery??? How does that work?
And what hope is there for this phone now? (I can't think of anything else )
Anyone have an idea? I've never heard of this before tbh!

Well, my problem has been sorted. In the absence of knowing what the hell I should do lol I managed to get a refund for the phone even though it was a refurb to begin with (something to be said for an honest seller who provides a 3 month warranty!) and I picked up a brand new N5x, which was unboxed on Tuesday. Not even 6 hours into setting it up, the phone started to get progressively hotter and then went into bootloop. Got into the bootloader and tried a factory reset - all seemed OK but halfway through the setup process it bootlooped again. Fortunately it was still within the 2 year warranty, and LG didn't argue about authorising a repair for a phone which didn't get even half a day's use on it lol
Authorised Wednesday, walked into the service centre Thursday and a 1 hour wait later had phone in hand with the PCB/motherboard replaced. Has been working fine (and cool!) ever since. Definitely feel lucky to have hopefully dodged a bullet on this one.
Bonus that they upgraded from 6.0 to 7.2.1 while they were at it; apparently LG considers nougat the "latest" stable version for the 5x.
