How to debug my Boot.img ? - Xperia Z3 Q&A, Help & Troubleshooting

Hi,
I try to made my own boot.img for the z3 but it's bootloop. I can't access to recovery or adb.
My boot create log on the phone but how access to read them ?
I try to flash a boot.img that work properly but i can't access to my logs. (they are delete probably)
Any idea for debugging ?
Thanks for all
Thomas

Copied from stackexchange (google is your friend):
There's a couple of ways to do this:
cat /proc/last_kmsg > /sdcard/last_kernel_message_log.txt
dmesg > /sdcard/kernel_boot_log.txt
plug in the usb cable with the smart-phone switched off. Then issue the command adb logcat from your Windows cmd or Linux terminal, it will hang waiting for the device to come on-line, now power up the smart-phone. The logcat should start scrolling off then.

hi, thanks for your answer. Like i told you in my previous message i can't access to adb. I'm stuck at the sony logo and there is no adb logcat at this moment.

You still should be able to either read out dmesg or last_kmsg.
Those are kernel related logs and should help you find the cause of your bootloop.

ok, but how ? I only got fastboot available

You could try to boot a recovery.img using fastboot and then getting the logs, but
I seriously don't know if the logs get deleted if you boot with another recovery.

Yeah if you are in fastboot mode you can type "fastboot boot recovery.img" with "recovery.img" being a working recovery.img file in the directory/folder of your fastboot/adb command line on your PC.

Can you get into fastboot? You might want to try reflashing your boot and system partitions. I believe it was BeagleBoy that grabbed them off of a stock Xoom Wi-Fi. You're already unlocked I imagine. Should let you flash those right back in and start fresh.
This guy got out of a semi-brick by doing something similar.

If you can get into fastboot, you should be fine. Don't panic just yet.
Try reflashing the stock boot.img and system.img files through fastboot. I did it a few days ago http://forum.xda-developers.com/showpost.php?p=12832155&postcount=33
You can find boot.img and system.img for stock wifi xoom on the OP of that thread.
Failing that try the semi bricked solution.
I hope you solve your problem.

Power off the device.
Then hold Volume Down and hold Power on at the same time.
it shows "Starting Fastboot protocol support" and stopped there. what this mean? =(
that means you should be able to get it running again.
follow the first message in this thread:
http://forum.xda-developers.com/showthread.php?t=1010568
probably from the stuck at 'dual core technology' bit...
but I think this is what you should follow:
adb reboot bootloader
fastboot flash boot boot.img
fastboot reboot
adb remount
adb push bcm4329.ko /system/lib/modules/bcm4329.ko
adb push tun.ko /system/lib/modules/tun.ko
adb push scsi_wait_scan.ko /system/lib/modules/scsi_wait_scan.ko
adb push cifs.ko /system/lib/modules/cifs.ko
adb push vold.fstab /system/etc/vold.fstab
adb reboot
you might also want to pick up the stock wifi images:
http://forum.xda-developers.com/showthread.php?t=1017398
and flash them using:
fastboot flash system system.img
fastboot flash recovery recovery.img
(you've already flashed boot.img above).

If you're lucky, your computer will connect and typing in "fastboot devices" will show an entry for your Xoom. You do not need to start with ADB if you're already in fastboot mode.
From there, flash the boot.img for the proper Xoom version you have. You may also want to flash the system.img as well.
From there, simply try to reboot using "fastboot reboot". Make sure your Xoom starts up. If it does, you're pretty much good to go. I'd root from there manually.

That's not necessarily true. My PC can no longer detect my Xoom in any way whether or not it says "Starting Fastboot protocol support" or "Starting RSD mode 2". I can't get it to say anything else.
I used to be able to get into fastboot. That's how I bricked my Xoom... By trying to oem lock it with what I was hoping to be clean boot, system and recovery image files for the wifi.
Now, I can't even get back in to oem unlock or flash. RSD lite doesn't pick it up in RSD mode 2, but does pick up my old RAZR phone.

What sort of computer do you have? Can you copy and paste what you see when you type "fastboot devices"?
Copy and paste from your command prompt (or Linux terminal) and let's see what you've got.
ok. will report once tried. thx very much =)
Okay. If you can get into fastboot (check by "fastboot devices"), all you should need to do are these two commands if you're connected:
Code:
fastboot flash boot boot.img
fastboot flash boot system.img
fastboot reboot
That should get you close to stock first.

[Q] Bricked! How to fix/get fastboot or bootloader with ADB

Hi mates,
My TF300t(unlocked) is bricked:crying: Im only able to go into TWRP(2.6.3) but i can't go into the bootloader(for using fastboot and co)
BTW, there is no Rom installed, so if i start the tablet (no matter if i press Power+Vol Down or not) i allays end in TWRP.
My TWRP is also "buggy". It has some problems, like: Unable to mount... / Unable to set emmc bootloader message.... / unable to find partition size for xyz.... So i cant use TWRP to flash/install something and factory resets didnt work.
There are a lot of good guides how to UNBrick the tf300t, but they all need fastboot. Does someone knows how i could Fix fastboot with ADB? ADB is working fine. Maybe i can use ADB to fix TWRP or even better Fastboot.
Sry for my bad english, please help my

Yes, I do! Hopefully you have "Minimal ADB and Fastboot" installed on your PC.
First of all, check whether you are able to reach fastboot protocol by pressing Power and Volume down together. Fastboot protocol should appear. That means now you have ADB access via USB and you will find further help here: https://forum.xda-developers.com/sho....php?t=2179759.

I Have a similar problem and the link above goes to a 404 page.
In my case, My Tablet boots directly to the TWRP splash screen, and freezes. I can get status and serial number via ADB, but that's all.
If I try to reboot (via ABD) I get no response.
The device appears on Windows10 devices list, but Fastboot can't see it (I get that "<waiting for device>" message). I guess that my TWRP is damaged somehow, only part of the ADB protocol is getting up.
That happened when I tried to clean up the cache and ended up messing it all up.
The Status on ADB says that the tablet is on recovery mode.
Is there a way of flashing TWRP with ADB only? Or it is bricked forever?
Thanks for any help

[Q] Nexus 5 power button doesn't work anymore

Hi everybody,
So, there is my problem, I bought the nexus 5 in November. I rooted it.
And the last wednesday, while using my phone, the power button decided to not respond anymore.
The phone still worked but two days ago the batery became empty and now I can just go in the "bootloader menu" and the "download mode".
Google accepted to replace my phone, but I really want to save my files. And like you certainly know we can't save our files with the phone Off.
But my phone is detected in this two modes.
I installed the nexus driver but I still can't open my files.
I pretty sure there is a way to save my files, I searching and trying but nothing work, I would open my phone if I can activate the power button manually but I don't know how.
If you have any solution, I'll take it.
Per-haps the ADB can help me ? But I don't know how to use it.
Thanks a lot for reading.
Have a good day !
Ps : I'm new here please be gentle if I don't understand directly
And sorry for my poor english.

You can use a fastboot command to boot into recovery: fastboot boot path/to/TWRP.img if you have TWRP Recovery.
Then you will be able use to use adb commands to backup your data.

Nope because you only BOOT and not FLASH TWRP.img. Actually I say TWRP because I have this recovery but I think you can use this command with the stock recovery. You just have to use recovery.img file from the factory images instead of TWRP.img.

Did you rename the downloaded file to "TWRP.img"? The file name must be the same into your command prompt.
Copy TWRP.img into your platform-tools folder then open a command prompt from this folder and enter: fastboot boot TWRP.img
The path is the directory of your file you want to use. If you open the command prompt from the folder you have TWRP.img (platform-tools) then you don't need to mention the path.
I think the bootloader needs to be unlocked first for "fastboot boot twrp.img" to work? Isn't it? If unlocking wasn't necessary, everyone would've just booted recoveries to root their phones. (so that the sdcard doesn't get erased).
I sincerely doubt that the OP has an unlocked bootloader.

What exactly did you wipe, and how did you screw up? To find out more about your situation, boot to your recovery (which version, btw?) and run these commands:
Code:
adb shell dmesg > dmesg.txt
adb shell cat /proc/partitions > partitions.txt

Im afraid I wiped everything.I think my mistake was wiping in stock recovery instead of TWRP..thus it only boots to TWRP now.
I tried those commands but my machine was hanging like it was waiting for the device so I am going to uninstall and reinstall the windows drivers and ADB/Fastboot and do the commands again ,Ive been at work since this morning so ive got some honey dos then I can start trying it again.
Thanks so much!
When I run the commands as shell I get the ` # <[6n in front of all entries ( I assume thats bc Im booted to recovery not fastboot) and the end result is always "not found" ie: shell not found , adb not found ect....
When I type adb shell sometimes it just hangs, the dmesg command actually writes a file but its an empty file and the terminal just hangs
Im pretty sure if I cant figure out a way to delete this TWRP Im never going to be able to properly use ADB/Fastboot ths never reinstall an OS and decent Recovery..

No - can you get the tablet into fastboot mode?
Either by holding Power and Volume down when booting up or, in recovery, issue
Code:
adb reboot-bootloader
What do you get with the command
Code:
adb devices
when in recovery, and if you can get into fastboot mode:
Code:
fastboot devices
Also, you still haven't told us which recovery version you are running.
We had to use _that's bootit.ko to get it out of recovery into fastboot...
Then it was a flash of the stock Asus blob ...
Got him up and running . :good:
@DarkDarwin can you add SOLVED to the thread title ...
Thx Josh

I went out and got a bigger SD card (64) to try and implement the DATA2SD script.I think I was successful as I now have new folders there named Android and Data that I didn't have before...However,I wonder if I was supposed to wipe anything before I re-flashed the ROM after inserting the formatted , partitioned SD...
I have to admit the I/O issue is extremely aggravating..I cant believe Asus marred an otherwise excellent device like that.
I was sent from this topic: http://forum.xda-developers.com/showthread.php?t=2179759&page=23
To this topic, I also have a similar problem.
Read my comment from last topic:
Ok, when I boot up in android, I can use adb command reboot bootloader to boot in the bootloader.
When i then try fastboot erase system, it's still hangs with waiting for device..
The bootloader is not stuck, i can again boot up android..
it's impossible to open terminal, because the touch is going crazy..
Hmm, i'm trying something else.
I still had 10x tf300 for repair. there are multiple cracked with 5184n version.
I installed the cracked display assembly on this one, then i just can normally use the keyboard.
Will try again in terminal
edit: what command to use in terminal?
Dont forget, i flashed the recovery, but didnt install supersu zip yet..
The strange thing is, when im in the bootloader, i can use fastboot flash recovery command, and write the right recovery.
It's also succesfull (sending recovery OK, writing recovery OK)
But, the transformer hangs in the bootloader after finished (freeze)
When trying to reboot, it's automaticaly going again booting up twrp (enter password)
So it didnt write the recovery, by example if i write twrp 2.7, it still gives me 2.6.3.0 (installed first time)
extra information:
If i'm booted up, and then adb reboot bootloader, then try fastboot commands, they don't work. it keeps saying waiting for devices.., the fastboot commands like flash works for 1 second then the tablet freezes.

So, fastboot commands are not working, how to get the bootloader normal again and that it reads fastboot commands?
Look in Device Manager on your PC and check that the Asus ADB interface drivers are there
Wow what a difference DATA2SD and ROM2SD make!

Hey there, I may have a solution, I am very busy right now working on a step by step for a few diff unbricking methods...
Yes this sounds like a windows driver issue.... Let me see if I can find some info on this topic ..
Thx Josh

Like I already told, I have flashed dozen of transformers. Adb commands are working (like adb reboot boot loader) it works when booted in android and when in twrp (password). Fastboot commands give waiting for device, but fastboor flash recovery works but the transformer then freezes..
After this problem I already have flashed 3transformers correctly.

Why would it be a windows driver issue? Other transformers I can flash succesfully adb and fastboot fully working

Sounds like you know more about this then any of us.
Not all Transformer tablets use the same drivers.
Window is very picky about what driver it will use for what device ...
