[HELP] Nexus 5 stuck on bootloop + bootloader locked + can't access recovery - Nexus 5 Q&A, Help & Troubleshooting

Hi,
I have come here seeking help for repairing my Nexus 5 which is stuck in bootloop. The phone wasn't rooted with possibly no custom recovery and it's bootloader is locked. And I am not sure which firmware was on it. And I also don't know what was done to it for it to become "bricked" as it was given to me in that state.
I can access the Bootloader Mode (a.k.a. Fastboot) but when I try to enter the Recovery Menu it gives me an Android logo with the red triangle with "No Command." written underneath it. And since the bootloader is locked, I am unable to flash a Stock ROM on the phone.
I have somehow managed to "temporarily" unlock the bootloader by entering the following command.
Code:
fastboot oem unlock
But, as mentioned, it is temporary as whenever the phone is rebooted it automatically gets locked again.
So I tried entering that command then I immediately entered the following commands to flash the stock 6.0.1 recovery.img
Code:
fastboot erase flash
fastboot flash recovery recovery.img
But in vain, as it still gives me the "No Command." Android logo when I run the Recovery Mode. I have also tried the same procedure with the TWRP recovery.img but with the same results.
I have also tried launching the flash-all.bat from the stock 6.0.1 right after running the bootloader unlock command mentionned previously. But it fails as i guess the flash-all.bat is programmed to reboot the bootloader before flashing. Thus re-locking the bootloader right before attempting to flash it.
I have come here seeking for help as I believe XDA is the most active Android community online.
If my post is somehow against any forum rules here, please be indulgent as this is my first time posting on XDA.
Thanks in advance.

At first, fastboot erase flash is not a working fastboot command. It is used to erase a partition: boot, cache, data...
Is your bootloader relocked after typing this?
fastboot oem unlock
fastboot reboot-bootloader
In the stock Android, press Volume up when you see "No Command".

Sounds like the EMMC is dying. http://forum.xda-developers.com/goo...-unbrick-nexus-5-stucked-qualcomm-hs-t3043301 you can try using the tool here, test the EMMC and RAM, it'll pretty much confirm it.

Yes the bootloader gets re-locked. And pressing Volume Up doesn't work either.

I've tried the tool and I can't get it to work properly as it gives me an error saying "partition.txt does not exist. Please extract the file from the total binary image."
UPDATE: I just got it to work. The SDRAM test passed but EMMC test failed. So that means it's hard-bricked right? And is changing the motherboard the only way to fix it?

I have a phone that does exactly the same thing. Swapped out only the motherboard and everything is fine again.

I suspect a hard-brick, so I am strongly considering it. Would you know if motherboards are carrier specific? Meaning if I get a motherboard from another carrier's Nexus, would it end up changing the carrier of my phone?

Any motherboard from any carrier will work as long as the model numbers match. In Canada, every N5 carried by all carriers is the d820.

[Q] Nexus 5 Soft-Bricked ! Please Help :( (Locked Bootloader, Stock Recovery)

Hello Guys,
I'm now in deep deep trouble as my Nexus 5 has got soft bricked and now stuck in a bootloop. Yesterday evening i unrooted my device, flashed everything to stock and locked the bootloader back because i was getting a really awful battery life upon rooting. Hence thought of reverting to stock. So flashed the stock image of 4.4.2 and setup my phone just like it came from a factory. Only thing i did this time was disable some Google Apps i.e Play News, Games & Magazines, Movies etc. Till midnight it was working too good with only a marginal battery drain on idle i.e 1% in 2 hrs or so.
Today morning when i woke up, i just entered the PIN code and unlocked the homescreen and then it just got stuck. I restarted my device and since then, its just stuck in a bootloop and whenever the phone tries to restart the OS, its gives numerous errors all related to Play sErvices and something like android.process.acore and Media.
I tried to factory reset by going through the stock recovery but even in that it gives the errors " Failed to mount /cache" and "Failed to mount /cache/recovery" with invalid arguments in the brackets.
Now i can't even flash stock as the Bootloader is in Locked State. I'm able to flash unlock Bootloader but when it asks to restart "fastboot reboot", it again gets stuck on the Google Play services error resulting again in locked state. That leaves me with a LOCKED BOOTLOADER, STOCK RECOVERY & NO USB DEBUGGING ENABLED.
What can i do now to get my device working people ? Feel like :crying: since its happened. Moreover, i can't RMA it as I'm now in a different country from where the phone wasn't purchased.

The tool specifically asks for Unlocked Bootloader and like i've already mentioned, its in a lock state. To unlock that, i need to have USB debugging enabled which i can't enable as i'm not able to even see the lockscreen, just stuck in a bootloop. :crying: I'm able to launch the Fastboot Mode and also partially unlock the bootloader but as soon as i type the command "fastboot reboot", the device again goes into bootloop starting the cycle again
Any more suggestions guys or should i assume my Nexus to be a paperweight ?

Go to the stock recovery and format cache.. Do it a couple of times till the /cache errors go away and then go to the bootloader and flash the stock factory images again. After flashing the stock images, don't boot it up, head over to the stock recovery and perform a factory reset and then reboot!

You can use command in fastboot "fastboot oem unlock" to unlock then reboot in fastboot again, and try this instruction (since you unlocked you should be able to do this).

(BTW you dont have to reboot after bl unlock.
fastboot oem unlock
then flash stock images iwhtout reboot)
What? USB Debugging doesn't have to be enabled. Bootloader unlocking is done from fastboot via 'fastboot oem unlock'.

Bitdomo tried you awesome tool which gave me a slight hope that could revive my Nexus but sadly it didn't :crying: Memory size is matched 32G but userdata erase fails and at last the Download FAIL error is there I just don't know what is preventing the Cache and User Data to erase. Same is the case in Stock Recovery as well.
Can you please get me a solution on this. Would be highly obliged :good:

Successfully unlocked bootloader finally and installed TWRP. Booted in TWRP and performed Data Wipe and it failed. Again unable to mount /cache /persist /data etc commands showed. Then it tried formatting using make_ext4fs function but it failed. Swiped for a factory reset and it failed.
Used your ADB command afterwards and it displayed first daemon started successfully on port 5037 and then error in cmd : device not found.
What next ?
EDIT : Just noticed on the TWRP screen that my internal storage space is being shown as Zero (0) MB Now does this means my flash storage has died ? If that's the case and i need to RMA it, how to relock the bootloader , reset tamper flag and load stock recovery so that google doesn't cause any warranty issues. Please help me in that case as well.
EDIT 2 : Using fastboot, tried flash stock cache.img and userdata.img, it failed. When i flash system.img it went through perfectly. Also, got to know that the steps which you mentioned earlier, TWRP was booted temporarily and bootloader was unlocked temporarily. So does this means i don't need to relock or flash back something ? And, if i've unlocked and relocked the bootloader numerous times, how do i reset tamper flag ?

You could try one more thing. Format the /presist partition, For some reason it magically fixed other's devices, like for this guy and for an other in that same thread, but if you format it you will lose your wifi and bluetooth mac address, and some kind of DRM stuff. I made a tutorial how to fix wifi and bluetoot mac address problem after the formating, but I cant tell anything about the drm kind of files, because I still didnt get answers form the guys in that thread. That could mean they are experiencing no problems. Here is the zip which formats persist partition.

I tried all sort of things before finally giving up. Ultimately sent the device for RMA. Thanks for your inputs as well
@bitdomo, i have realised it was a case of dead memory chip only. I managed to relock the bootloader and reset the tamper flag (oem device info showed Tamper as "false") but now my only cause of concern is the LG Flash Tool. When i flashed the KOT9H firmware, it changed the original device version as mine came with 4.4 OOTB instead of 4.4.2. Can Google refuse the RMA citing this now ? Rest all, the kernel, recovery, bootloader, tamper flag is all stock. I coudn't even change that back to the original device version as i couldn't transfer any zip to the internal storage as it was dead.

Google can't get your actual device factory version, because it is only visible with lg flashtool, and that tool is an internal lg software. Google has nothing to with that tool.
By the way this lgfalsh tool makes your phone offical, because this is the offical tool used in LG service centres!!!!
Can you imagine a guy at google who takes your phone flashes a custom recovery, reads back the misc partition and search for the factory device version in the hex code. Then he checks your phone serial number and sees 310K then denies your rma request because your device factory version cant be that because in oktober 2013 there were no 4.4.2? I think no.
But if it bothers you then, you can flash krt16m, or if your nexus 5 had to do big update ~150 mb ota update then flash kfs78n if your device is D821 or flash kqs81m if your device is D820. Converted roms work too without problems I have tested them.

I have already sent the defective one for RMA so there's no question of flashing any files now. Google sends the new replacement device and and lieu of that they block temporarily the device's price for a period of 14-21 days in which the service centre ppl check for the issues what got the device in. And i think LG only is handling that as it made the device ? So my question still remains now can the LG guys intimate Google that the phone was flashed. ? But on the positive, the flash tool was of LG and it can't be turned unofficial What say ? I don't wish to pay again for a new device. If the service centre guys gives a thumbs up that phone indeed died as a result of hardware failure like emmc chip, then the card block is removed.
BTW, i am not aware whether Google itself handles the service or asks LG to do the same! Any inputs ?

[Q] Can't boot, recovery keeps dissapearing

I have searched and tried different things but I'm getting nowhere. I have been running Purity rom on this for a while but when I woke up this morning, I found my screen black and only being able to boot to the bootloader and and google screen (which quickly goes away and goes black again). When I tried to go to recovery at first I believe it was just shutting off. Now it goes to a light black screen.
The first thing I did was flashed the factory image .bat file and everything seemed to go ok but when trying to go to recovery after it went to the light black screen. I turned it off and it booted to the Google screen then off again. Then it booted to the google screen and it froze that way. I can always get it back to the bootloader screen and got it to recovery once by flashing TWRP again using ADB.
TWRP opened once and I tried to do a factory reset but it couldn't find anything and couldn't mount to anything. I got it back to the bootloader again but the recovery has disappeared again. I tried to flash the factory image again but it definitely failed this time.
Please help.

Lock your bootloader then reboot to fastboot. If the lock state remains locked try LG flashtool. Link in my signature. If the lock state reverts back to unlocked, then you have to rma your device. If that is the case can you check the variant text in fastboot for me? There should be D820 or D821 and after there should be a letter E or H in (). I want to know that letter in the (). Thanks.
Dont forget to report me your progress

Hey I'm using "fastboot flash recovery recovery.img" and that's what I've used in the past. I've had a fully functioning rom with fully functioning recovery for a while until yesterday.

Ok thanks I'll try this and check the text in fastboot after work today. Thanks for the responses guys.
After reading some more last night I'm afraid it's an emmc problem but I like to be proven wrong sometimes.
Maybe also try this?

I actually have that thread open on my computer. It was my next attempt of repair before starting the thread late last night. Thanks for the suggestion I will certainly try it.
Update: I tried pushing Philz recovery to the phone which seemed to work fine until I selected go to recovery mode. It just went back to that barely light black screen. I'll try again when I get home. Going to try Bitdomo's advice about locking bootloader first.

Bitdomo I'm trying the Flashtool but it's staying at 0% on the firmware update and nothing is popping up on computer or in Device Manager. Had no connection issues prior to the brick or with adb/fastboot. My Ports aren't evening showing at all in DM even if I select show hidden devices.

I honestly wanted to do that but it seemed too easy. I was trying to lock it like I did before when i had to send original back to T-Mobile. Sorry and thanks.

Lock your bootloader then reboot to fastboot. If the lock state remains locked try LG flashtool. Link in my signature. If the lock state reverts back to unlocked, then you have to rma your device. If that is the case can you check the variant text in fastboot for me? There should be D820 or D821 and after there should be a letter E or H in (). I want to know that letter in the (). Thanks.
Dont forget to report me your progress

Ok so it stayed locked so that's a start. I'm back in download mode again but it's staying at 0% and nothing on computer.
I tried to re-download the factory images and flash again using adb. It failed again. Here's a picture of what happened:
Unzip the zip and use manual flash commands. Clikc the link in my signature and read my "adb and fastboot. What is it?" thread of you're unsure of the commands.

You have "remote: flash write failure" error. It means your emmc (internal storage) is broken and you cannot modify the data on it. You have to rma your device.
Just for matter of research can you enter to fastboot and post the variable line here?
Mine is: hammerhead D821(H) 16GB

Sorry I meant to tell you yesterday... D820H 16GB. Should I still be able to toggle the tamper tag so they will take it back with no problems? Or am I screwed?

You should be able to if you managed to lock the bootloader. The name of the zip does not came into my mind which you have to flash, but you have to do it with the adb sideload command because you cant copy anything to your phone, or use adb push command to push it to the "/" folder because it is mounted to the ram which you can write not like your storage . If you bought your phone from google it does not matter you have tamper flag set to 1.

Ok thanks. I haven't quite figured out the adb sideload function yet. I tried doing it through TWRP but it just sits there and does nothing after selecting. Maybe I'm trying the wrong thing. I got my phone from T-Mobile so I'll need to solve this. Thanks for the help.
This phone is being a real a-hole. I'm trying to boot to stock recovery but it just sits on a screen with a really big android with wiggling antennae. I pressed up+power many times but it stayed that way. So I tried booting to TWRP again and it did but went immediately to an "OpenRecoveryScript," had a little bar at the bottom for a while with some other stuff on the screen, then turned off.
I tried stock recovery again and it went to the little dead android this time but still nothing when I press up+power.

Trying to flash TRWP Moto Z recovery - not working

Hey everyone, longtime lurker here finally going to try to get involved more since I just got a new Moto Z and I don't have much of a background with motorola hardware/software. I'm trying to flash recoveries through fastboot and I can't seem to get it working. I'm probably going to wait a while before I try again since there is not much support for the moto z yet. I am running MPL24.246-45 v6.0.1 XT1650-03, I have unlocked the bootloader through the instructions on the motorola website.
On the bootloader screen I can confirm it is now unlocked, but everytime I flash the TRWP recovery through fastboot I get the error message: "<bootloader> img not working or corrupt". I am trying to flash the most recent twrp recoveries for moto Z (twrp-3.0.2-0-griffin.img) but wasn't able to successfully flash it.
Coming from a samsung background, I might be skipping a step or doing something wrong. I am running the bell canadian firmware. Since I messed up my partitions on my last phone I want to be careful with this one, I mostly want to figure out why I am getting this error while trying to flash the recovery when
my bootloader is unlocked and when I check "adb devices" my moto is being read.
Thanks!!

didn't try it yet, but did you try renaming it to recovery.img (if on windows be sure extenstions are shown so it is not actually recovery.img.img) and run (didn't see which command you are using:
Code:
fastboot flash recovery recovery.img
but search around forums about encryption thing and similar

I've tried both with the original twrp name and extension as well as with renaming it to recovery.img, didn't seem to make a difference. If I am connection to the device itself does that mean that adb/sideload is installed properly? I mean I was able to unlocked the bootloader so I would assume so.

i really don't know then.. if you successfully unlocked bootloader then fastboot should be ok. you can check in device manager. it should be bootloader iterface not adb interface there (you got me confused with mentioning adb so I am just writing to be sure).
also check if your device is shown when typing
Code:
fastboot devices
or try redownloading twrp.
otherwise I am out of ideas, sorry.

Sorry for my confusion with adb/sideload - from what I understand I need both to be able to connect to my device (correct me if im wrong). In the bootloader menu I see "flashing_unlocked" which I believe confirms my bootloader being unlocked, but then at the top of the text right under the dead android guy I see "AP Fastboot Flash Mode (Secure)" could that be an issue?
I can retry downloading the recovery from the TWRP site, but I know I'm downloading the official one already, just can't put my finger on why I'm getting that error message if others are doing it successfully.
thanks for helping :good:

You're at the bootloader, it says Flashing Unlock so yes your bootloader is unlocked and you should be able to flash TWRP no problem.
Did you recently install this .45 firmware? Are you sure that TWRP wasnt actually flashed? I see lots of errors like this from the bootloader and its usually just rubbish.
The twrp does not show the actual memory value of my cell phone and does not let me paste ROM backup, from insufficient memory? how to support it?
I updated my phone to .45 when I bought the phone I believe 1-2 weeks ago, it's definitely NOT flashed as the flashing process runs for 0.2 seconds and fails. I can even boot in the stock recovery afterwards confirming that nothing flashed. I wish I knew what I was doing wrong? possibility of drivers not installed properly?
Before I try and flash recovery I check USB debugging, OEM is unlocked, don't verify ADB files and accept Unknown sources. Is there anything I'm missing?

I've been doing fastboot flash twrpname.img after opening cmd terminal with SHIFT-MOUSE2 in the designated folder. I have not tried that command specifically what's the difference between doing fastboot flash/boot as far as flashing a recovery.img
edit: I've read on different articles that people sometimes try and flash from the recovery menu? I understood it has to be while your are on the bootloader screen, could it be something to do with that? Or is it still a possibility the drivers may not be installed properly.

With fastboot boot you send recovery to your phone and ask it to boot on it without really flashing it...
It's useful e.g. to take a full stock backup including original recovery, to test a recovery prior to flash it or to use TWRP to root BUT remain on stock recovery...
Not on all phones it works, but on Moto Z should....
P.S.: you have to be on fastboot screen not on recovery when flashing...

by fastboot screen you mean the bootloader menu right?
I've been accessing cmd from designated folder with .img file in it
- adb fastboot recovery
- fastboot flash recovery.img..
and I get the "img not working or corrupt" after it tries to flash it (lasts 0.2 seconds) and nothing is done.

Right, bootloader screen. Enter on it by key-comb... not by command...
Even the real flash take same time... Sending seems to work, is something on verify that doesn't "like" it...
Try to download again recovery and/or check its MD5...
if reading correctly (and what I told you yesterday) command is
fastboot flash recovery recovery.img
and not
fastboot flash recovery.img

try following this instructions: http://forum.xda-developers.com/showpost.php?p=69065373&postcount=14
and download eu rom from here: https://mirrors.lolinet.com/firmware/moto/griffin/official/RETEU/
i don't know from which ROM you are coming, don't know if downgrading works, but this was onl RETEU ROM i could find.
I have the exact same phone and I've upgraded to Nougat but I got my TWRP working. You need an unlocked bootloader and after upgrading to nougat, the option "unlock OEM" need to be enabled again.
I've used this TWRP : https://dl.twrp.me/griffin/twrp-3.0.2-0-griffin.img.html
Also I tried to only boot on it at first with the command fastboot boot twrp.img then I saw it was working, I flashed it with fastboot flash recovery twrp.img but got the error : (bootloader) image not signed or corrupt . But I booted the recovery from the bootloader and TWRP was working even with this error.

Google Pixel Flasher Using QPST

Hello
I have a Google pixel 128 GB device but recently it got bricked after an ota update. Unfortunately my phone is not rooted or unlocked. So I could not do anything under fastboot, also adb is crashed.
So the phone is bricked. But it can be rectified using QPST is edl mode I suppose. But as of now there is no such development for qpst for Google pixel.
But there are many users they face the same issue recently.
Is there any chance of development for it?
you said bootloader ! you mean the phone can boot into bootloader mode ! after that you said edl mode ? i dont understand. please explain. i may help !
*The Phone Goes into Fastboot with no problems.
*In Fastboot Mode if i try to go to Recovery, The Phone Reboots and does not go to the Recovery But it Keeps on Rebooting.
So the Recovery Partition of the Phone might be Corrupted.
So im looking for ways to Flash the Recovery partition with QPST or any other methods.
Fastboot Doesn't Help Because the Bootloader is locked.

I do believe I've tried this to no avail on a Verizon g-2pw4100-022-b (the "b" probably stands for "brickable").
I'm stuck in the same situation:
Power+vol down - bootloader
Bootloader to recovery - boot loop
Bootloader to barcodes - barcodes show
Edit: power on only leads to constant screen flashing unless you hold volume down for bootloader, at which point you can vol up once and power down.
Can't flash a recovery, can't flash an OTA since that requires adb sideload, which is part of recovery, and can't flash a factory image with the bootloader locked, which is only unlocked under development tools.
One thing to note is that in the bootloader screen, both "b/l" and the one below it (radio?) both say "n/a", which leads me to believe the December update from Verizon could be the cause.
Suggestions as to how to proceed are greatly appreciated.

I have a Reddit thread how to activate qpst .
You can also "adb reboot edl" if your PC can recognize your phone at least.
If not, power button and volume up(or down, I don't remember) for at least forty seconds sometimes brings it up
But then you'd need firmware to flash with qpst and I'm not sure how to go about doing that

TF303CL boot fail

Hi!
Unfortunately there is no topic for Asus Tf303CL, but since it is the member of the TF3xx family I hope this post can stay here.
The problem is, that I'm stuck at the Asus boot (static white) logo and can't go further in booting.
I've tried ADB, but there's no response on the "adb devices" command.
I've also tried fastboot, but only two commands are woriking:
"fastboot devices" comes back with an alphanumeric number and
"fastboot continue" turns off the tablet.
The other fastboot commands are returning with the message "fastboot failed <remote failure>"
So finally I've found some hints that maybe with xFSTK I would able to fix fastboot, then with the Asus Flast Tool I supposed to be able to flash the stock raw rom (which I've already done before).
But unfortunately xFSTK is ether not working (no communication) or I'm using it wrong. As far as I know TF303CL has Intel SoC with Baytrail platform, so I used the Baytrail B0 tab in xFSTK and I've loaded the *ifwi*.bin file which I found in the stock raw rom.
Is this the right way to fix fastboot or I have to do something else? Or the tablet may has hardware defect?

I think it was a good idea to open this thread. To my mind your device is really very close related to TF300T and TF700T. The OS is Android 4.4. So it might be worth to attempt to flash a CR like "KatKiss - Nougatella"
But before you may start is to clarify following:
1. Is the bootloader on your device unlocked?
2. Is there already any custom recovery like TWRP on your device?
3. Can you boot into fastboot protocol by holding Power on and Volume down together?
If you cannot get access neither through ADB or Fastboot, your device is bricked for good. Sorry!
1. Is the bootloader on your device unlocked?
I have no idea. It bought it brand new, but I already had to debrick it once with Asus Flash Tool about a year ago. So raw firmware was flashed. I don't know whether flashing a raw rom with AFT requires unlocked bootloader or not.
2. Is there already any custom recovery like TWRP on your device?
As far as I know it has stock recovery.
3. Can you boot into fastboot protocol by holding Power on and Volume down together?
I think Power on & Vol down is the key combination for recovery mode. Power on & Vol up is the combination for fastboot. I can't access to recovery, but fastboot may partially work.
If you cannot get access neither through ADB or Fastboot, your device is bricked for good. Sorry!
Whit adb
Code:
adb devices
command has no response. With fastboot I have a response on the
Code:
fastboot devices
command, it returns some kind of an id. Beside this
Code:
fastboot continue
makes the device to turn off. Other fastboot commands (as I wrote) are returning with the "fastboot failed <remote failure>" response.
These are what I have tried so far:
reboot, reboot bootloader, update, flash (several images), erase cache, erase data

People usually unlock their bootloader to root their device or install Custom ROM on it. I think your bootloader is still locked. On the other side in the left above corner of the dark screen should appear the hint "the device is unlocked" during the boot process.
For the TF300xx family there is an Asus unlock tool V8 available. I don't know if it is useable for your device. Please call Asus support and ask them about that. On the other hand there is a tutorial here: https://qitapso.com/how-to-unlock-asus-transformer-pad-tf303cl-bootloader/
Should I try to unlock the bootloader?
