Nexus 5 stuck at boot...

paulie420 · 16 Oct 2022, 21:35

I purchased a used Nexus 5 hammerhead and installed Ubuntu Touch using UBPorts...
System worked, and I played around for a few weeks.

Phone battery went dead and when I charge and power on, it hangs on the Nexus 5 powered by ubuntu (Supported by ubports) screen.

If I hold vol down and power, I can get into the UBPorts bootloader;
FASTBOOT MODE
PRODUCT NAME - hammerhead
VARIANT - hammerhead D820(H) 32GB
HW VERSION - rev_11
BOOTLOADER VERSION - HHZ20h
BASEBAND VERSION - M8974A-2.0.50.2.30
CARRIER INFO - None
SERIAL NUMBER - xxxxxxxxxxxxxxxx
SIGNING - production
SECURE BOOT - enabled
LOCK STATE - unlocked

fastboot sees the device in fastboot mode;
xxxxxxxxx0233716 fastboot

I can use the vol keys and boot into recovery mode.
adb sees the device;
List of devices attached
xxxxxxxxx0233716 recovery

Here are some outputs from adb shell that might be helpful;

I can boot up a twrp recovery image;
fastboot boot twrp.img

I tried to burn that recovery image;

 paulie420  archframework  ~/adb  fastboot flash recovery twrp-3.7.0_9-0-hammerhead.img 
Sending 'recovery' (14416 KB)                      OKAY [  0.880s]

Finished. Total time: 2.175s

But UBPorts overwrites it (I think) before it can boot.

At any rate, I just want to get Ubuntu Touch back in full - thats all this device was ever for... is my eMMC fried? Or... any suggestions at all? Thanks.

Hi @paulie420

The easiest route would be to use the ubports-installer again.
You can leave the "wipe data" option unchecked.
If it doesn't work, you can try to revert to android and then run the installer another time but your data will be lost...

MrT10001 · 17 Oct 2022, 10:56

@paulie420 Follow as @AppLee said. If it fails on the reinstall, try with a new battery
If that fails, the eMMC chip (storage) may have failed which basically bricks the device, unless you can get another motherboard.

paulie420 · 17 Oct 2022, 23:41

@mrt10001 Thanks for the two replies; I've tried UBPorts installer several times. When ya'll say try to revert to Android, do you mean with the packages with the naming scheme "hammerhead-krt16m-factory-fb4041cc.zip"? Inside, the files it comes with are installed with a "flash-all.sh" script? Cause if so; yea, thats what I thought... but when I attempt even the first "fastboot flash bootloader bootloader-hammerhead-HHZ11d.img", it fails;

Sending 'bootloader' (2506 KB)                     OKAY [  0.310s]
Writing 'bootloader'                               FAILED (remote: 'flash write failure')
fastboot: error: Command failed

I've even tried the subsequent commands in "flash-all.sh", which do the following;

$ fastboot flash radio radio-hammerhead-M8974A-1.0.25.0.17.img 
Sending 'radio' (42033 KB)                         OKAY [  1.820s]

Device version-bootloader is 'HHZ20h'.
Update requires 'HHZ11d'.

fastboot: error: requirements not met!

So... I think I've tried most of the things that might get me somewhere... as stated, the three things that 'change' anything that I can get done are;

$ fastboot boot twrp.img
Sending 'boot.img' (14416 KB)                      OKAY [  0.638s]
Booting                                            OKAY [  0.116s]
Finished. Total time: 0.763s

This one is neat; it actually boots the Nexus 5 into the Teamwin Recovery Project 3.7.0_9-0... in recovery mode. However, I dunnno where I can pivot from here. I thought that I'd install twrp, but when I burn that with;

$ flashboot flash recovery twrp.img
Sending 'recovery' (14416 KB)                      OKAY [  0.740s]
Writing 'recovery'                                 OKAY [  1.099s]
Finished. Total time: 2.034s

OK, that sounds promising... but when I "fastboot reboot bootloader", it goes back to the UBPorts fastboot menu. LOL! twrp website said that you might have to hold vol up + power, to boot into recovery so that the old bootloader doesn't auto-write over twrp, but I haven't been able to get that process to... work. I thought if I got UBPorts OUT, maybe UBPorts installer might then work.... UGH.

LAST, if I boot into recovery mode I can use adb to;

adb push twrp.img /sdcard/
twrp-3.7.0_9-0-hammerhead.img: 1 file ...d. 9.6 MB/s (14761984 bytes in 1.466s)

But I dunno what that really does for me - can I install the above twrp.img from within the UBPorts recovery, or the fastboot menu???

Thanks for the attemps, anyone - I think I've done a lot on my own and... just dunno.

paulie420 · 17 Oct 2022, 23:47

@paulie420 Last thing... when I try to do like... in recovery mode all those options, like Install Update from Internal Storage. When I do that, I see;

E:failed to mount /cache (Invalid argument)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
(AND SEVERAL OTHER E:Failed/Can't lines...

??? bad internal storage?? Cause where my boot fails is where Ubuntu Touch should boot - and if its gone.............

Keneda · 18 Oct 2022, 13:17

@paulie420
Did you try :

@mrt10001 said in Nexus 5 stuck at boot...:

@paulie420 If it fails on the reinstall, try with a new battery

paulie420 · 19 Oct 2022, 01:17

@keneda Nah, I don't have a 2nd battery, nor really the desire to even unplug the old one to swap out if I did. I'll prolly just buy another device for Ubuntu Touch - I was just giving it a good go at trying to save/fix this one - but I'm fairly sure the eMMC is dead... if I write data to /cache, /userdata, etc its gone with a reboot...

I thank ya'll; but I think the day I devoted to messing with this one is the last.

Keneda · 19 Oct 2022, 07:44

@paulie420
Dead batteries can cause serious hardware issues, so emmc may not be the problem.
Changing battery saved my mx4, thanks to @MrT10001 .
