Bootloop after Factory reset - Nexus 5 Q&A, Help & Troubleshooting

Hi guys,
got my nexus 5 yesterday and wanted to flash AOSP. But at some time, something might have broken, because now I get a bootloop after factory reseting via Kwongger Nexus5 Toolkit, ADB sideload via CWM, via zip, ... I tried everything, wiped everything, erased anything via fastboot. When I boot into CWM, there are messages like "E: cant mount cache, invalid argument", so my prediction is, that something bad happened to partition table or likely.
Does anyone have any idea how I can fix this? I searched the whole internet up and down, comparing to other devices like nexus 4 which I use right now.
Every idea is well-appreciated ALOT :good:

Go into recovery and clear the caches and do a data factory reset and see if it boots, if it doesn`t go into fastboot and flash a Google factory image. A good advice = DO NOT USE TOOKITS. Good luck bro

Why haven`t you made a nandroid backup first after you flashed TWRP? Have you cleared the cache after flashing TWRP: fastboot erase cache in adb? If nothing else works reflash the stock recovery and clear cache afterwards or reflash the factory image as a last resort.

I am new to it all.
I found the device using adb, but yeah I dont have a back up of the rom.
I downloaded the stock rom in the rom section but adb gave
archive does not contain android-info.txt
archive does not contain android-product.txt
error: update package has no android-info.txt or product.txt

Yet another boot/brick issue

Have an XT926 Maxx with an unlocked bootloader. I can wipe partitions and flash custom ROMs just fine. I can also fastboot back to stock images. But for some reason, I can't get past the boot animation. For example, on the stock rom, it'll display the 'DROID' image upon boot and play the 'DROID' sound but then suddenly freezes, then reboots (over and over again). I've gone into factory recovery and wiped data/cache and still have the same issue.
I've searched the forums and was not able to find anyone with the same issue.
Any suggestions? Am I screwed? Perfectly good phone otherwise!

If all you're doing is wiping data/cache, there's a possiblity that there might be some bad data in there still. I would also format data, as this will get rid of everything. Wiping data doesn't always get rid of everything. If you are fastbooting stock ROMs, always FDR after you flash, prior to booting into OS. Also, since your BL is unlocked, you need to load up an aftermarket recovery like CWM or TWRP. None of the new ROMs will work on stock recovery.

Thanks for the reply.
Yes, I know about the need for TWRP/CWR when flashing custom ROMs. I reverted back to stock recovery when I fastbooted the factory images. Using stock recovery, I wiped Data and Cache so not sure what you mean. What's FDR?

FDR is Factory Data Reset. It's generally a good idea to boot back into recovery and FDR after fastbooting.

Ah, yes....I've done that numerous times. Still will not boot. Is there a way to erase the partitions and rewrite them? Perhaps they're corrupted or something.

I was, for some reason, able to get it to boot up once today. I was able to get to the 'Power off and Insert SIM' screen. After powering off, though, it would no longer fully boot into the OS. Still bootlooping.
Less than an hour later, i got it to boot up yet again. Not sure how, but it's booted up and now with my SIM installed. I know if I reboot, it'll happen again.
Anyone have a clue what it could be? Anything I can do before shutting it down that could help?

you can re-write the partitions using this tool, for the 926 only

Data Partition Corrupted

I just got my Nexus 5 a while ago and I just unlocked the bootloader and flashed TWRP and as soon as I opened TWRP it basically crashed and rebooted the phone is a boot loop but now when I go to TWRP the log says Unable to mount /data and I can't do anything. Does anyone have the solution? I knew I shouldn't have rooted -_-
Have you flashed a stock cache.img yet? Thats usually the first thing to try.
Sent from my Nexus 5 using Tapatalk
Uhh
Not yet right now I'm currently using Wug's Toolkit and seeing if that helps then i'll try that. Do you have the link by any chance?
OH thank GAWD its working again thanks for your help though
what did you do in the toolkit?
Generally the consensus here is to not use toolkits. There are 2-3 "Johnny Opposite" members, but the masses of senior members see them as a bad thing.
I explain what happend.
You opened bootloader, but you flashed twrp instead of start the phone to let stock recovery finish the formating. You flashed twrp and rebooted to twrp. Twrp found the commands in the memory or on the misc partition to do a factory reset then reboot, but that format command is not compatible with twrp, so that commamd was skipped and then twrp rebooted your, because that was the next command in the line. Now your started booting with an unformated cache and data partition. The easiest way to solve the issue is to do a format data in twrp to format data partition then a factory reset to format cache.
So In the toolkit I basically flashed the stock rom and it basically factory reset EVERYTHING so now its working again thanks for the help! Now to try this over again

Why create a new thread?
Full wipe/factory reset, then flash the entire factory image set.
Look here if you don't know what to do:

I've done it more than 10 times the full wipe and still not working. Same with factory flashes...
Are you getting any errors when flashing stock with fastboot?

Are you trying to flash the lollipop or kitkat factory image?
Anyway, after flashing when you get the bootloop, go to fastboot and flash a custom recovery and then do a factory reset, cache and delvik cache wipe. This should do the trick.

i did all that you tell me. i do a factory reset, cache and dalvik but my N5 doesnt work. Continue in an infinity loop :/
I downloaded the image-hammerhead-lrx21o, radio-hammerhead-m8974a-2.0.50.2.21 and bootloader-hammerhead-hhz12d.
Any idea?
Try flashing a kitkat rom by the "Ncry" tool. Click the Restore menu button and select device and rom.
impossible
always stuck in and infinite bootloop... i think any component (hardware) isnt working well

Flash the whole image (radio, image, bootloader) in fastboot by typing in cmd: flash-all. This will wipe the device but will not cause problems.
i did it too bro, but nothing...
Here im posting a video i recorded for you... (i put a song from youtube to mute the sound of my room)

Looks like a hardware problem. Either Google RMA or LG Repair.
I bought it in Amazon
May i have rma if I bought on Amazon?
LG Chile doesnt has official repair...
So I had to buy another cell, a moto x 2014.. Bye nexus
it looks like hardware is at fault, can you relock the bootloader?, do that if so, i dont know if amazon do rma, contact them and find out,
strange if you get no issues while flashing,
I think so. I will check about invoce and RMA.
Thank all of you

Lollipop doesn't boot. Kitkat can't access internal storage

Hi folks.
I'm facing a really weird problem. My friend's N5 doesn't want to boot with Lollipop, it shows the boot animation, but nothing happens, more than an hour and nothing.
I tried to flash back to kit kat. It indeed booted, but just to say that the camera and gallery has stopped, and gallery couldn't find any storage. When I go to the storage section in the settings, it doesn't show the pictures, music and other sources, just available space, cache and apps.
I tried to flash a custom rom to, but they all give me bootloops.
I never had this problems with my n4, so i don't know what to do anymore.
Any solutions?
Flash lollipop with fastboot. Then boot into the stock recovery and do a factory reset. Everything will be fine.

You flashed the factory image with FASTBOOT and still had this problem? You sure?
Hmm. Try fastboot formatting all the partitions and then flashing the image again. Can't hurt.

Yes, i'm absolutely sure. I'm used to use fastboot to flash my Nexus 4. I downloaded the proper factory image from Google and flashed it using both flash-all.bat and manual input in the cmd.
I tried to erase the partitions, format using TWRP, and install a custom ROM.
With twrp I can see the the internal storage partition, and even mount it to access by computer. But when the device boots, it just can't see the partition.
I put a song in the internal storage with twrp just to test, and when the device booted it didnt recognize the song, but when I got back to recovery, it was still there.
It seens that the problem is in the internal storage, but I don't know how to fix, and what could have caused it.
* Sorry, my english is bad :/

Tried that. I first used fastboot erase, didn't work, and then I use twrp to format to another fs. After that, I flashed the image again. Still nothing.

I have wiped everything lots of times.
It's the first time I have a hard time trying to fix an android phone...
Now I flashed kitkat image again. It booted but with the storage problem. Then I update via notification, and it stuck in lollipop boot animation.
I will let it booting through the night. Or it boots after a couple of hours or the battery dies.

Yeah this seems kinda crazy. Usually when stuff gets messed up like this a factory image clears it up. In your case, I honestly don't know what else to recommend. Sorry I can't be of more help.
Replace internal storage, nothing else you can do
Nothing worked in the end. My friend will send the phone to tech support.
Thank you guys for the help.
:good:
