I had a crash yesterday when my phone screen just blanked out while it was on charge and was getting very hot. After unplugging it, i rebooted the phone and after the initial logo, no screen was coming on. I could feel the haptic feedback but nothing on the screen. I again rebooted nothing, luckily i got into recovery by power+3D+vol down and restored old image.
But since that time i've tried the following methods:
1. Installed new image
2. Factory reset stock phone and camera still hangs.
3. Software UPdate via LG software update tool and clean fresh install.
4. Emergency phone restore as the boot got corrupt one time.
5. Restored using previously working image(s). tried 2 separate dates and roms.
Nothing works for the camera and doesn't take picture even by pressing 3D button.
EDIT: Update. Managed to finally get the camera working after lot of clean installs of CFW. Only prob is when i click storage and press SD Card option it hangs. Tried many times and even on another ROM but it just hangs when switching storage to SD CARD.
Is there a hardware issue or a software one?
Any idea or tips that could help me restore my camera?
Hi,
As the title says:
Have a Nexus 5 running the latest lollipop build that has been working properly for a while (Phone is a Google refurb from November 2014, replacing my original N5 that had battery issues; Warranty expired Feb 2015)
4 days ago, it randomly rebooted and then got stuck on the "Optimizing apps" page on initial bootup - would never go past a certain app number
First tried wiping cache - which didn't complete even after 48 hours
Next tried full wipe from recovery, which worked but then shutdowns still happened
Reflashed all stock images (Phone is stock, not rooted) last night - problem still exists with random shutdown - but I can always get past initial setup; shutdown problems happen a little while later during use
Wiping cache from recovery now gives a "Could not mount /cache/" error in recovery
My hypothesis - that there's sector(s) on the eMMC that's borked. It's a 32GB phone - is there a way I can flag off a certain sector as "bad" and put the cache partition somewhere else? Also open to other suggestions, including replacing the eMMC chip if needed (I can find someone set up for BGA work).
I considered doing a file check from Philz / TWRP, but since the issue persists after a full reflash/reformat I assume that it's not a software bug.
Thanks in advance for the help, let me know if there's any other information I can provide that might be useful.
Anyone?
Hey, my phone has been playing up and generally malfunctioning lately. It seems to work fine for a day or so before freezing, and either rebooting itself or forcing me to manually reboot it using power + volume down. This seems to send it into a bootloop where it generally freezes during the Samsung animation with the pulsing squares. This sequence continues with me manually rebooting, also trying to boot to safe mode and to recovery and after various attempts, i successfully got into recovery without it freezing on the blue android.
I then decided to factory reset as a last option, having looked around on forums for solutions. However, I now do not know what to do as it seems to have frozen during the factory reset. I dont have screenshots but the script reads as follows :
dm-verity verification failed. . .
-- Wiping data. . .
Formatting /data. . .
Formatting /cache. . .
It has been on that for the past 30 minutes and so i have assumed it has frozen. I'm afraid to force another reboot in case it is accessing memory, any suggestions on what to do?
It is up to date on fully stock software, has never been rooted and i have never attempted to do so. Also only around a month old.
Any help would be appreciated, thanks
I did not try to perform a factory reset yet, but my S6 shows the same instability issues.
Random self reboots with getting stuck at the boot animation.
I furthermore cannot enter the stock recovery mode (get stuck at full cyan screen with android logo), only can access the ODIN mode atm.
Booting that device atm is a hit and miss.
(everything stock, never touched that device in the XDA way! )
Update: I had to repair my S6 as instability increased even more.
Samsung licensed repair shop exchanged the mainboard of my S6.
All is fine again (except wireless charging, but I guess they broke it while repairing)
Hi, I bought a used Nexus 5 and it has been causing quite some problem when booting. I flashed Cyanogenmod in it and it works fine for a few days. After that it keeps having the same problems in the following order:
- It would restart on its own, sometimes some random app will fail functioning (it's never the same app).
- Turns off on itself without restarting. Can still be turned on normally.
- From there it gets worse and start bootlooping. On CM it loops around the part where it initialises the apps. On stock its the colourful stuff that happens right after the Google logo.
- Finally it just gets stuck in boot. On CM it's stuck where it initialises apps while for stock it turns off right after the Google logo appears.
I have tried the following:
- The persist partition fix described at https://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576
- Cleaning the power button and made sure it wasn't stuck.
- Re-flashing CM, did a checksum to make sure the files are okay
- Went back to stock, did a checksum too.
It's a used phone so I have no idea what it went through in the past. Anything I can do to fix it?
Try running the phone with a stock ROM without root. If the problem still happens, it's probably a hardware problem.
It didn't have root but I flashed a factory image (plus another round of factory reset too) and even locked the bootloader + reset the tamper flag this time. It's working fine now but the problems normally start a few hours/days later so I can't be sure at the moment.
If it does fail again which hardware is the one with the problem? The warranty's long gone so will it be easy to buy a new part and replace it myself?
The cheapest solution may be to buy a used Nexus 5 with a smashed screen and working internal components to swap out components.
I've got a Vodafone UK version SM-G920F that has recently started to freeze, crash and reboot constantly.
I managed to back up my data and perform a factory reset from the Setting page, but it crashed 10+ times during the install process (would freeze at various different stages, either rebooting on its own, or requiring a Vol Down+Power reset)
I'm now on a fresh install, but it's still rebooting constantly. I managed to use it like normal for an hour today, but right now it's just rebooted 3 times and won't even get past the Samsung loading screen without several Vol Down+Power resets.
What other options do I have? And is anyone aware of a known hardware issue that could cause this?
I was considering flashing a different ROM, but I'm scared it would reboot during the process and corrupt something...

Maybe a battery issue?
a friend just gave me his very same model phone with the very same issues.. if I find out anything I'll tell you here, or if you solve it first please write down what you did.
Thanks Vibbuz.
I've been trying to download a stock firmware to flash via Odin, but download speeds from Updato are really bad.
So I managed to flash a firmware after installing Odin on a Windows laptop (painful trying to get it to work on my Mac)
Firmware installed OK, but after boot I was getting a constant "com.sec.epdg" pop-up box that wouldn't let me use the phone at all. Not sure if that's due to the tsar3000 firmware?
Wiped the cache and did a factory reset after booting into recovery, and now it's stuck in a boot-loop again (95% of the time it hangs at the Samsung logo animation)
Just tried using SamFirm v0.3.6 to find the correct file. Downloaded a 4gb file, but several attempts to extract only gives BL, CP, CSC files but no AP (throws up an Unknown Error during process).
So still stumped!
Yet another update. Left Updato running overnight and downloaded a firmware.
Flashed it with Odin, claims to have succeeded but phone then reboots and hangs at "Erasing" stage (Android logo is spinning, then stops)
I'm starting to think it's pretty broken...
I've been having this exact same issue since June. If your phone happens to boot try activating power saving mode (to reduce cpu speed) as soon as possible.
It seems that doing that diminished the frequency in which my phone rebooted. If it also helps you it might be a faulty battery that can't provide enough voltage. (I'm not 100% sure on this part though, just thought of it because of the apple batteries drama)
Please post your results! Looks like a lot of people are affected by this and it would be great if we could find the cause of the problem.
I just read your thread actually! Sounds very similar to mine.
I've got nowhere. I don't think it's hard-bricked as I can still access Odin mode on the phone, and sometimes boots to Recovery, but it freezes and various different points and is currently unusable (either freezes at Samsung logo, "Erasing" part after installing firmware, or once it started to run though new device setup then froze).
Went ahead and bought an S8, but still want to fix the S6!

Hi I have same Problem I send the my s6 for repairmen that Saied me this problem related to mobile Hard drive.
I didn't believe it and try some official rom and a rom from Philippine GLB solve my problem for 3 M/o but now developed as same problem whitout any successful rom installation.
I think this problem from incompatibility google play store version to my rom. please flash a custom rom without google apps and immediately after installation turned off data and Wi-Fi internet after 2 day whit sim card whit out any change in setting can use it.
Hello,
anyone found some kind of solution? Happened to me also - freezing, restarts and then my S6 stopped working.. Sometimes I can boot to recovery menu, sometimes it boots up to android (and then freezes again), but the chances are almost non existing. Service man told me the same thing as @ghasemzm - eMMC failure. Yes, it is completely possible, but i don't wanna believe it, because they only tried to reflash the rom. I've made some "google research" and found that there were some issues in power IC on S6/S6E. Could this be related to it?

Will test the theory and let the group know.
So i have installed philipines latest update 6.0.1 i think with PIT file provided on Sammobile.
I have tested it for a day with normal ussage like i set up every other phone and it still continued restarting.
Figured out let me test with no google account signed in and the phone is working perfectly. For a full day.
So i dont know what the problem is but i will try again with google account tomorrow for a day see what happens.
After that will install 7.0.1 uk update with PIT file for it and test with that.
I have the same problem and I am quite sure that it is the mobile hard drive.
I tried to use F2FS but didn't find a working rom for that.
Samsung refused repair because of root.... Never Samsung again!
same issues here - any solutions found? My best guess is hardware fault...
