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.

While I was playing with my TF700 the other day I accidentally put it upside down resulting in pressing (& holding) the power bottom & volume down .. the device restarted into "Safe Mode"
I tried to get rid of it, but apparently I did something stupid which resulting in boot logo loop (the device is stuck at the second ASUS screen and refuses to boot)
* Note my device is Unlocked & I'm running the latest CleanRom version and I am kinda' experienced user :silly:
Anyway I googled this and I tried the following steps with NO success:
- Cold boot
- Wiping caches
- I also tried to re-flash a rom
which left me only with formatting & wiping data, BUT I tried this thing and it actually worked!
From TWRP I restored my last back up (which was a bit old) But whatever, It actually worked! and I have no problems whatsoever, everything seems to run as before, I also tried to reboot the device and it's still working!
I felt I should share this info with you, it might help someone :highfive:
- A few days ago my phone freezes while I am using it, and its stuck on the google screen. at this point, it's on 5.0.1 unrooted, unlocked bootloader.
- I try going into recovery and wiping cache and doing factory reset. I keep getting errors but eventually the wipes work. Still doesn't boot though. So I do this a few times. I got it to boot twice but both times it froze within 5 mins and back to the same thing.
- I fastboot 5.0.1 factory image, goes through. but still no dice - stuck on google boot screen.
- I research and find out about the infamous power button problem. it doesn't seem like thats the issue with mine because the buttons seem to work fine. whatever, i take it to a local repair shop (phone is out of warranty) and the next day they inform me that there is no physical issue and that their software reset worked. they used the LG factory firmware way of resetting the device.
- Got the device back, used it for a while. It was fine for the time being but it was on 4.4.3 and I got the 4.4.4 update. I go and unlock bootloader, flash 5.0.1 factory image and push TWRP+root.
- Doesn't boot again, stuck on google logo
- I tried a whole bunch of stuff and nothing worked. I ended up with flashing 4.4.3 factory image in fastboot and relocking the bootloader so I could take it back to the shop the next day. At this point the phone wasn't even turning on.
- The next day (today), I tried turning it on, nothing. I put it in the charger for a while, then turned it on.... and it booted! used it for a while, it's fine.
- Did 4.4.4 system update, it's fine.
- Unlocked bootloader, it's fine.
- Tried to flash 5.0.1 factory image and again same issue - stuck on google screen.
- Been dicking around the last few hours trying to fix it ended with flashing 4.4.3 again but same issue, I then put the phone into download mode and connect to the computer but I got a green screen something about DemiGod Watchdog HW reset. I did the reset.
- Phone booted up again! Did the 4.4.4 system update and then it started freezing and rebooting withing few seconds of use. Now it's back to being stuck on google screen.
- I am obvious gonna bring it back to the shop now but any idea as to what is happening here?

1.I presume the "DemiGod Watchdog HW reset" green screen came up after you gave the phone for HW servicing? If so then they could have knocked around the parts a bit to cause a hardware issue(not sure what causes it)
2.Check the MD5 of the 5.0.1 factory image.
3.Instead of factory image use the OTA zip file and flash in stock recovery.
So I used the LG tool myself to flash the firmware (4.4.3 is the only one available) and it worked fine. Updated to 4.4.4. Fine.
I then adb sideload the 4.4.4 - 5.0.1, and stuck on google logo again .................im pulling my hair out this is so weird.

1) yes this was after.
2)i tried adb sideload.. ill try that good idea.
can't flash ota.zip in recovery. only adb and that didn't work.
think i'm just gonna hang on to 4.4.4 then for now. tried everything.
Just an update. I was running 4.4.4 just fine but the phone froze and went back to the Google screen again.

Might as well rma
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!
My Nexus 5 device seems to have many issues, some that I have resolved, some that appeared next. Here is some history.
- The first issue that I had was that some sensors were not detected, and the others were not working. Sensor testing applications found some of them (but they didn't work), and others like the accelerometer didn't even show up in the list.
- For a couple of months now, once in a while (at each ~2 weeks), I find my Nexus 5 powered off, and bricked (the boot process stops at the Google logo)
- Each time, flashing the original images worked (simply using flash-all.sh)
- After one of these flashes, I had no wifi. Flashing the original image did not work. Rooting/installing TWRP recovery, erasing cache, etc. did not work. I finally got it to work by installing a custom ROM, and never understood why it worked.
- Device bricked again, flashed the original image back. Wifi still works, but no SIM card detected. Absolutely no sensors are detected. The device reboots after a couple of minutes. This is where I am now.
What I tested so far :
- Rooting the device, running e2fsck on the partitions, some of them showed errors. None of them show bad sectors.
- Moving the content of /persist (to try to fix the SIM card problem)
- Flashing custom ROM, stock ROM, old ROM, different radio, etc.
- Removing/inserting the SIM card
I really am out of ideas, does anybody have ideas that I could test? I'm starting to think that I have an hardware issue but I still hope to repair the device... The issues started to appear right after the guarantee was expired.
EDIT: I found many threads about power button issues, however right now if I boot to Android the device reboots after few minutes, but when the phone is in TWRP recovery it stays open and never reboot. I therefore think that the reboot problem is not related with the power button.
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...
