Google Nexus 5 :: Bootloop From Root App Permissions
Aug 30, 2015
I'm not really and expert on flashing stuff on Android. I was pretty comfy not rooting my phone for more than a year. TBH, I didn't really need it, because I was not a power user, but I've recently installed a root app called King User (King Root, etc.). It made things easy for the very few apps I could not use without root permission. However, when I received the latest OTA (5.1.1. security update) I had to disable root authorization in order to install it. So I disabled it using the app's built in authorization setting.
The OTA update failed and gave me the error with the opened up android and the red exclamation mark. So I thought that the app messed something up. Disabling in house did nothing. Uninstalling it did nothing. So I decided to replace it with SuperSU using this guide: [URL] .... After SuperSU deleted KingUser and updated itself the phone remained stuck inside a bootloop. So I figured this replacement process messed up permissions.
My bootloader is locked and I have no custom recovery (because like I said, I just needed temporary root access for a couple of apps and wanted to avoid the hassle). When I enter Recovery mode in default fastboot it gives me the "No command" error (probably because of SuperSU permission).
Now I don't even know if the phone is rooted or not. USB debugging was not enabled last time the phone was on and now I think I'm stuck in this point where nothing works without something else. Doing a full recovery now would probably be asking for a lot, but right now, I would be happy if I could just do a factory reset or something...
I've been using Nexus 5 since Nov '13, but this is the first time i'm facing a serious issue in my device.I was browsing through Chrome and my Battery was 73%, all of a sudden my device rebooted and here comes the main issue/problem.My device is suffering a boot loop only displaying the google logo for 3-5 seconds and again it reboots.Occasionally the boot animation starts but no success, again it reboots.
I tried to enter fastboot menu, it enters but it doesn't stay there for not more than 2 seconds. So I can't make any choice over there.I tried all the combinations (VOL UP+ Power, VOL DOWN+Power, pressing all the buttons), but its of no use.My device is out of power now.Even when I plug my device to charger/computer its not showing the battery charging animation instead the reboot loop occurs.I suspect it can be a problem with the power button in the board.
My device details: I'm running Stock Android 4.4.4 with stock kernel.(not modified any system files) TWRP recovery V 184.108.40.206 UNLOCKED ( @present Locked) ROOTED. @present Unrooted)
My Nexus 5 is stuck at the flying dots after Lollipop OTA update. Already try factory reset. Cant connect to my Lap (running Windows 10) because it says in the device manager: Unknown USB Device (Device Descriptor Request Failed), so I cant manually update the driver and cant access it with ADB and Fastboot tool. The device has no USB debugging enabled. In the old computer where I used to connect the device and has the drivers installed says the same thing in device manager as my new laptop.
Nexus on bootloop tried every method ,most of them . Flashing new factory image is also of no good. Cleared cache , factory reset and still on bootloop. On flashing lollipop factory image it gets stuck on boot loop and on flashing KitKat factory image or using any custom ROM like cyanogenmod it gets through boot but is unable to detect sim and apps like play store and camera keep crashing and refuses to open.
A colleague of mine (yes honestly it wasnt me) reported that his Nexus 5 was stuck with as he put it "the wee android man in the middle of the screen" Then, before he give the phone to me to look at he said that he had tried some things with images to get it to work but it didnt work. so truthfully i am not sure what he has done or not done but the phone is stuck as follows:
When you turn the phone on you have the android robot which looks like it is doing an update.
I have gone into bootloader where I have the option to Start, Recovery Mode, Restart Bootloader and Power Off. The lock state in the Fastboot mode shows unlocked.
No matter which option you take (Even Recovery) it just goes back to the android screen that looks like it is trying to update....i cant get to the android with the exclamation mark that would allow me to do a factory reset. At this stage of the game im not worried about any lost data etc.
Well as the title says, I modified framework-res.apk to change navbar dpi (using apktool and copying original META-INF folder and Manifest in my compiled apk). The problem is that when I push the framework to the N5, it wont boot.
adb reboot recovery adb shell mount system adb push framework-res.apk /system/framework/framework-res.apk adb -d shell chmod 644 /system/framework/framework-res.apk adb reboot
And I also tried to take a logcat when in bootloop (idk if it's stupid or not):
Failed to parse /system/framework/framework-res.apk: Failed to collect certificates from /system/framework/framework-res.apk
I used adb to install TWRP onto my Nexus 5. Now it is in a bootloop, and TWRP does not seem to be able to mount anything. When it reboots it looks like it automatically goes to the TWRP where it says it is running OpenRecoveryScript but it is unable to mount anything. I tried a boot start to Recovery and it worked but when i tried a factory reset it says the same thing.
I had a new nexus 5 running on android 6.0 ,I was planning on rooting my phone , had the oem bootloader unlocked - the twrp installed , however after flashing the elementalx and beta supersu , my phone was in a bootloop for 4 hours. I did everything as told in the tutorial video for rooting and now i think that by flashing the nexus 5 stock rom it might be useful in recovering my phone... How to flash stock rom on nexus... when I tried getting into the recovery mode it was still in twrp ...
I was using the Cataclysm Rom for months without any problems. Today I restarted my phone (I do this every other day, when it gets a little bit slow) and it stuck in bootloop.
I tried wiping dalvik/cache, doing a factory reset, reflashing Cataclysm, nothing worked. So I decided to go back to stock (using [URL] ....) and I'm still stuck in a bootloop every time. I can access and use fastboot/stock recovery in the normal way, but it won't boot.. What I could do?
My unlocked Nexus 5 during kingroot rooting process my laptop shut down and now its in a boot loop stuck at logo. I can bring up bootloader and ADB but no back up or recovery on phone hard drive.exactly what do I do?
A friend gave me his nexus 5 because it have a problem, one day the phone was stuck on boot screen (the flying balls of lollipop) and to add difficulty (can't be easy right?) windows doesn't recognize the phone but it recognize my nexus 5 with the same cable on the same usb port....
I get a "Device Descriptor Request Failed"(the usb port on the nexus seems to be ok) but my nexus get none ... Is it a hardware issue ? I heard that there is issues with nexus 5's motherboard...
I can enter the fastboot and recovery but after a wipe, still stuck..... Not rooted and booloader locked....
Last night, I left my phone on charge. It was working normally and the software was functional etc. However, once I woke up, the phone was constantly restarting itself, and wouldn't load past the boot animation. I tried to load up fastboot to enter the TWRP recovery, however, the phone froze on the load screen. I should also add that my custom boot animation was replaced by the CyanogenMod mascot.
I tried to use WugFresh's NRT to flash a factory image of Android 6, however, the command terminal indicated that each process had failed. This did not restore the phone to its original condition.
I should also point out that I have been running a CM 12.1 nightly, which has been very stable and I have been using this nightly, without major problems (bar the infrequent system UI crashes) for a couple of months. It is obviously rooted and I have a Nandroid backup, which I can't access for aforementioned reasons.
So basically my phone just doesnt show up on my computer or any computer since like Android 6, not to big of a deal since i use airdroid to transfer files now and then, but i really would like to root again, so was wondering if its possible to root Android 6.0.1 - Build: MMB29S without a PC?
i can backup all my files if needed, and i have rooted in the past so my bootloader is unlocked
I'm currently running Android 6.0 DP3 on my Nexus 5 and have to perform a clean flash due to battery drain issues. However, this will make me go through the whole backup and re-setup process again - backup images, backup Whatsapp, backup all documents and download, flash the phone, restore everything, log into the different apps, set up Gmail accounts etc. Obviously, I'm not looking forward to that it's basically also the reason which has kept me from trying different ROMs on my phone in the past. I know that there is Titanium Backup just for that job, but it needs root access and I can't root my phone because this will trigger the "phone isn't secure"-alarm of my bank's super cautious TAN app which will stop it from working (just like using Tasker does, which obviously sucks).
SO i was doing a factory restore from nexus rootkit - i must have forgotten and let it use the nexus 6 files -- it did a reboot after some flashing but never booted - it's dead aside from having access to the reserve boot loader, i have access to nothing else. I saw a similar post of someone flashing nexus 4 firmware on accident and he fixed it this way, but i think the command lines must be different since his command lines were using nexus 4 directories
I have a small question regarding a nexus 5. Is there a way to know if my Nexus 5 has ever been rooted? In my office, we are having a connectivity problem with a nexus 5 and after talking with google they request us to send them the phone. They asked if the phone is or has been rooted which, I guess, voids the warranty.We use the phones for developing software and research proejcts, and I know that some of them some times are rooted, some times use not official-roms, etc.
So despite it looks that the broken nexus 5 is a stock one, I'd like to check it and to make sure that it has never been rooted. Is there a way to do so?
Apparently the Nexus 5 is not rooted: play store apps say so, and the bootloader is locked. Still, I cannot be completely sure that the phone has never been unrooted. Is there a way to check that?
I bought a Nexus 5 from amazon and when it came in and I set it up, it was like setting up a brand new phone. However, when the setup process was done and I was brought to the homescreen, it had SuperSU in the app drawer. I was scared because I do not want a rooted phone, so I installed Root Checker and that said that my phone was not rooted. However, if I launch SuperSU in order to uninstall it, it gives me a pop up that says that "There is no SU binary intalled" and stuff, and I cannot access the app further than that. Is there any way to uninstall it? (Also, if I go to the google play store to uninstall, it just says that it'll uninstall all updates from this app).
I've been looking around, but I can't find anything to suggest root is available on the stock kernel. CF-Autoroot doesn't work for 6.0, and so far all I've found is root for custom kernels but I want all stock.
Recently installed cm12 nightly via flashify. Lost root access. How to get it back? Also I entered an email id in the email app. Now I wanna delete it but there is no option. I already deleted in settings but it still stays in email app. How to sync contacts via people on cm12?
I tried to root my phone, but I cant get past flashing the superSU.
I am running the latest version of android and I tried both TWRP and CWM.. I get to flash the custom recovery and boot up, but as soon as I try to flash SuperSU the phone gets stuck into bootloop. (also when I use CWM phone automaticly overwrites the custom recovery to stock, I know how to fix this but I must get the root access first though...)
Currently I reflashed factory Images and I am using my phone completely naked only with vital apps. But I am not willing to back down, I would like to find the fix and Root it till the end.
I have a banking app refusing to run since it thinks thatmy phone (Nexus 5 running 5.1.1) is rooted. Only problem is that it's not. Or at least i think so....
I have understood that the banking app concerned checks if the phone is rooted by checking for SU binary in systembin and systemxbin, and fair enough, by xbin contains the SU file. I was rooted on 4.4 (or 5?) using towelroot. The bootloader has been locked all the time. I never rooted on 5.1 and above since I didnt want to wipe, and as it didnt matter much to me.
My questions are
1) Can I restore the root in some way, given that the SU binary exists without wiping the data? I tried Superuser app but naturally it failded to update the binary.
2) Can I delete the SU binary somehow without root access? At this point i only have read access to the systemxbin directory.
