I have an A71 that is about a year and a half old. Last week it got stuck in a boot loop. The only screen that I could access was the download screen. So I downloaded Odin and flashed all the appropriate firmware onto the phone and it rebooted back into the boot loop. Am I out of luck? I have 200 bucks still owed on the phone, and dont really want to buy a new one, out of principle, if nothing else. Any thoughts on getting it back up and running?
I had the same problem just now.
So what I did to get to work was:
1. Hold the Volume Up + Power Button until it goes into the Android Recovery Menu
2. Select Wipe Cache Partition
3. Select Wipe Data/Factory Reset
4. Reboot System

hi all
i am trying to do a factory reset to my nexus S but i faced some problems, the phone cant be reset to factory settings. my phone is on 2.3.4 and is rooted
i had tried the following steps
1) going to Settings>Privacy>Reset phone
after i confirm to wipe everything, the phone rebooted and it will stuck at the "Google" logo (in words) with the fastboot unlock logo at the bottom. i took off the battery to shutdown the phone (anything i press at this moment does not get any response from the phone) and start it up again. once it is started (it get pass the google word logo if i do it this way) all my application and even my themes are still there
2) shutting down the phone. press volume up + power button. choose recovery
same thing happen as above. it cant get pass the google word logo and once i restart the phone by plugging out the batt, it went back to previous state without wiping anything
i search online guide and also youtube video and all of them shows that the recovery will bring you to a android with a exclamation mark (in the triangle) but i cant get to the screen. i had left my phone there for 30 minutes but it is still stuck at the google logo.
Please help

Make sure to update it eventually because you could run into issues when flashing stuff if your recovery isn't up to date.
No problem!
Hi Guys, I'm in a bit of a panic with my Nexus.
Looked in my pocked yesterday and the phone was randomly in a boot loop, just getting up to the google logo, then rebooting.. this was weird as the phone was working throughout the day. The day before I had installed Faux v5 (and I have cataclysms rom)..
Followed the instructions from [TUTORIAL] How to flash a factory image | Return to stock | Unroot your Nexus 5
to rever to stock image.
I run the flash-all.bat (using method 1 from Post1), which seems to complete successfully (writes to the device and it reboots a few times), but after this the phone gets stuck at the Google logo,
I cant get to the final two steps (which is wipe data/factory data reset), because in the step before where I select recovery, it just boots back to the google logo - no recovery. It will stay there all day, unless I hold power & volume down, then I can get back to the bootloader.
Since this failed (I have flashed the flash-all batch twice using different usb ports... but no joy.
If I run the fastboot device info, - it correctly shows my bootloader is unlocked...
I have tried to relock it, but hit the same problem, (if I run the fastboot boot c:\twrp.img etc) - it just wont boot into a recovery..
I am at a loss.. any help would be greatly appreciated...
I have also tried flashing a custom recovery (twrp & cwm), and I have the same problem with both.. they flash, but then I can get to the bootloader, but cant launch a recovery.. just gets stuck in a bootloop...
THANKS!
reboot bootloader (power + vol down)
go into recovery (the red triangle)
open up the recovery menu (power + vol up)
wipe cache
The problem I am having is I cant get into recovery.
I get into fastboot mode, I then hit volume up twice (to change from start > to recovery >).
I then hit power. But instead of a red! I get the Google Logo.. and I am back where I started.
Volume up & power does nothing, all I can do is Vol down & power, then I am back at the bootloader.. no recovery..
Hello! I unlocked bootloader succesfully, flashed philz recovery and everything was ok until i flashed latest CM snapshot (previously was on stock vanilla). Now im stuck at google logo and cant do anything! Anyone got any idea whats going on?
P.S. It seems i cant get into recovery, tried holding the power button, but phone just tries rebooting. Same for holding Volumeup+down+power...
Flash stock image in fastboot and start again

I'm guessing you didn't wipe everything before flashing CM??
1. Switch off your phone completely.
2. Hold down Power+Vol. Down till you enter the bootloader.
3. Go to recovery and wipe everything(system, data, cache, dalvic)
4. Flash the the rom.zip and gapps.zip and reboot!
Let me preface from saying I've had this phone and flashed countless ROMs on it.
Also the power button died on it (fast reboot etc problem) and since I had already ordered my Nexus 5 I just decided to rip the button off and use it for the few weeks until I got my new phone.
Now that its been a while I decided to see what I could do with it and wanted to boot. It wouldn't boot and was stuck at the loading screen for a good hour. So I went okay I'll just decide to use Odin and bring it back to stock. Followed the guide here to the T and 3 separate times all that happens is the phone is stuck at the S boot screen. Tried both stock roms posted.
Now since I don't have a power button I can't get into recovery (which I'm assuming is wiped but I have the Odin recovery ready to flash but whats the point?)
I tried adb/fastboot and the phone isn't recognized.
Any suggestions? Currently stuck at the boot logo for 1hr 25min. I'm aware of wiping the cache but I don't know how to do that without recovery.
Edit: So I opened the sucker again, got some foil and shorted the power button contacts and actually got to the stock recovery and did a wipe of the data and cache. Now booting fingers crossed. If this doesn't work at least I know I can get into recovery and install TWRP and a custom rom and see if that boots. However if this is a go then I'm good (only want it t run Perktv)
Edit2: So I couldn't get anything to install with TWRP (tried 3 different roms) so I went to the other recovery (Philz?)
Was able to install SlimKat (was using SlimBean when I was using the phone) and was finally able to install it... now its in a boot loop.
So I guess back to fully wiping (again) but I remember with these phones you had to do the wipe 2x which I didn't do. God I'm so spoiled with the Nexus.
Off to do that and see if that helps.
Edit3: Worked!! Woohoo
Hi there, having just the old casual phone crisis. I was running cyanogenmod 12.1 for awhile and decided to finally upgrade to a nougat 7.1 build.
I tried using this one https://forum.xda-developers.com/google-nexus-5/development/rom-dark-rom-t3492150 using adb sideload as I had tried a earlier one and the gapps messed up so I wasn't able to put twrp back on the phone. The rom said it had installed successfully but I wasn't able to sideload gapps, I kept getting an error status 255. I went ahead and just tried to load the rom without gapps and see if I could install it slowly through APKs. I managed to get past the initial android load and the services started up, and it got in an endless crash loop because the phone service wouldn't start. So I went to try and flash another rom and was going to delete the cache. When I went to delete the cache the phone hung for about an hour so I tried to just reset it into recovery mode again.
Now when I hold the power button and volume down key to into fastboot mode I can. I have access to the initial screen with the four options, but when I try to start recovery mode or start the phone my screen goes black, and it'll flash the dead android symbol with the error saying unable to mount cache, it only flashes it for like half a second then goes black and repeats every 10-15 seconds.
I tried holding power down, doing volume up, and letting go to do a hard factory reset but it does nothing. I also can't seem to access the adb sideloading anymore, I'm very scared that it's hard bricked, is there anything I can do at all to fix this.
Flash a new version of the recovery via fastboot. Then do a full wipe. After that install the ROM only! Reboot recovery (not system but recovery) then reflash the ROM (no wipe) and add everything else. Hope this helps you out.
The phone may not boot the ROM without wiping data if installing a 7.1 ROM over a 5.1.1 ROM.
