[Q] Nexus 5 Bricked! HELP!!! URGENT!

I'm kind of screwed and It's not even my mistake, I guess.
I clean flashed the Mahdi Update 25/04 yesterday earlier I had 03/03. In the morning I experienced 2 -3 random reboots and later only one random reboot after which my phone won't boot (bootloop). When i enter bootloader, it automatically selects "start" and boots into system and then reboots.
Once i got the chance and my phone booted fully. But then when I selected reboot into recovery so that i can restore a NAND. IT reboots, the team win logo shows up and then the cycle repeats.
Basically, i don't have access to recovery, my bootloader isn't stable (i.e. it automatically boots without selecting) so I'm unable to flash a stock img as of now. If and when my Nexus fully boots into system it stays the same for about 1 hr if i have any luck. PLz help.
From India. Unlocked Bootloader and custom Rom "Mahdi".

Have you tried using add to boot into recovery? If not also try to getting a logcat when it reboots, those will give us a little more of a general idea of what is actually happening.

First thing don't panic. You can't brick a nexus. You should be able to get into bootloader (volume down + power button) use Wugs Nexus Root toolkit from XDA forum. reload stock ROM in fastboot mode. I have done this lots of time. It's a draw back to being a tinkerer just can't leave well enough alone.

It sounds like your power bottom might be stuck to be honest.

I managed to somehow get into my bootloader and flashed the following
1. bootloader.img
2. radio.img
3. system.img
4. stock kernel (boot.img)
5. twrp recovery.img
I skipped userdata,img as i need to save my data.
I then went into recovery and did a factory wipe (not including internal storage)
My stock rom booted BUT the setup screen showed up and during the setup process it rebooted again and I couldn't mount my storage to backup.
MY MAIN PRIORITY IS TO COPY THE CONTENTS OF MY SD CARD Before flashing the whole stock image (including userdata)
Now when I type "adb version" in cmd I get Android Debug Bridge Version 1.0.31 but when I type "adb devices" whilst my phone is in fastboot mode, it doesn't list my phone. So i'm unable to "adb pull /mnt/sdcard"
I'm in the same situation with rare access to B/L (based on luck) and Recovery.
Plz tell me what to do when I am able to connect in bootloader mode (fastboot)
IF required I can upload a video showing that what problem I am facing.

To use adb pull you have to enter the recovery. You need universal naked usb driver 0.73 to make adb work in recovery. If you are on windows 8 or 8.1 you have to turn off the driver signiture enforcement befote installing the universal naked usb driver 0.73

I agree. It's a malfunctioning power button due to several reasons (moisture, drops, etc.). I had this on my Nexus S.

[Q] Wiped everything, can't get ADB to see my device anymore

Hi everyone, this is the first time i write here. I've been dealing with this problem for some hours now and it seems i can't get out of it alone.
Today i decided to wipe the N5 and install Lollipop. I downloaded the factory image, wiped everything from TWRP (i know it was unnecessary...), started to flash all the stuff from ADB...but i got some error. I tried again, and got the same error again. So i started to mess around...a guide told me to give adb the following commands:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
I think it was after this that ADB stopped recognizing my phone, and now i can't even get to the recovery. I tried uninstalling and reinstalling sdk and google usb drivers plenty of times, i even tried some alternative solutions like LGUnitedMobileDriver and Universal Naked Driver.
I can see that windows sees the device (which now only works in fastboot mode) from Device Manager, and that ADB is working (if i give the command "adb version" it responds correctly), but there's no way to make adb recognize the Nexus. If i just install the drivers, Device Manager shows it as "Android Bootloader Interface". A guide i found says to manually select "Android ADB Interface" or "Android Composite ADB Interface", and so i have done (i have to untick the "show compatible hardware" box in the installation process to see this options), but no luck.
Does anybody have any idea how to solve this? What may i have missed?

You need fastboot commands to flash images in recovery. ADB will only recognize the device when you have android running
Try "fastboot devices" command without quotes. It should detect your phone and return a serial number. If so, flash the images (see the sticky on how to return to stock and follow the method 2)

Adb and fastboot are two different things. ASB works in android or recovery but is not used for flashing. Fastboot works in bootloader.
I wrote an "adb and fastboot" thread. Use it uninstall your Google drivers and install naked.

Omg, it was that simple! Thank you guys, you were so fast :good:

If you downloaded the factory image, it seems like you just need to flash that with fastboot.
1). Reboot into the boot loader by holding down volume when powering on.
2). Type fastboot devices to make sure your phone is recognized.
3). Untar the image and execute the flash-all.bat script. This will completely factory reset your phone, including stock recovery. Note this will also delete your internal storage files.
If you don't like this approach, you can also flash the recovery partition with fastboot flash recovery recovery.img, where recovery.img is the TWRP image you downloaded. Once you boot into recovery you can restore a nandroid or whatever from there. Good luck.

How to install TWRP into the LG P500H from Koodo?

I have a Koodo LG P500H. I am having a very hard time installing TWRP.
Firstly Play store doesn't work. It has this old thing called "Market" that has some apps, but not all. Market eventually gets updated to Playstore, but I can't even find TWRP manager. There was another app in the Playstore that I tried called ROM Manager. It said it installed TWRP for me. I restarted the phone, and nothing happened.
Restarting and Holding power/volume down/home will show a picture that seems to be some sort of recovery mode. But it only run for 1-2 seconds before the phone restarts itself. Nothing happens.
I tried to use ADB. But after rebooting the device it just restarted without ever going into recovery mode. So the flash command just get stuck at "Waiting for Device." Does this phone even have a recovery mode?
This phone doesn't support Odin.
I am used to using TWRP. Without it I cannot flash the phone into new OS.
And every single time I fail, the whole phone seems to have reformatted. So I have to enter in my wifi password and gmail again. All of that typing on a very small keyboard takes a lot of time. I had spent hours on this phone without getting TWRP working.
Please help.

The problem is when I reboot into fastboot (adb reboot bootloader), the phone will go into "phone off battery charging mode". It never actually goes into the bootloader.

Ok I did the following and it seems fastboot and TWRP works now. Be sure to enable USB Debugging on your P500.
1) Fastboot tutorial (I did everything here. I hit "ok" on the LGMDP 1.5 tool as needed. Do not wait till the countdown timer goes to zero.)
http://forum.xda-developers.com/showpost.php?p=15122833&postcount=100)?
FastBoot Tutorial
1. Please download this (or from here) file and unzip it in to any folder.
2. Start LGMDP 1.5 tool with the phone connected (you need to have USB drivers installed) and click on Select Port
3. A separate window should appear like the one below
Just click connect
4. Another window will take shape (LGE Mobile security) with lots of options (links)
Click on the first upper right Browse and select the folder in with you have unzipped the files. You will get some errors that some image, table or headers are missing. Just click OK and in the end everything that should remain selected is Partition Table, APPSBL Image Header and APPSBL Image.
Now just close the window (click on x)
5. Now you are back on the main window and here you'll have to click on Download
6. You are almost done and from now on everything should go on automatically.
NV Backup
Autorestart in Emergency\Download mode and upgrade the files (you selected on step 4)
NV Restore (the last step) Do not disconnect the USB cable until the restore is done
Wait for the phone to restart in normal mode (your current rom).
That should be everything you need to do to get fastboot enabled.

2) Install PdaNet+ (This was the only thing I did in this tutorial. It fixed the usb driver and the fastboot can then communicate with my PC.)
http://forum.xda-developers.com/showthread.php?t=1350733
http://pdanet.co/a/
(Note: On top of Partition Table, APPSBL Image Header and APPSBL Image in step 4, I also selected the TWRP image file as my RECOVERY image. Not sure if this make a difference. )
(Note 2: I think you can also get the LG drivers here.)
3) Restart, hold down power + home to boot to the fastboot. Or in ADB type adb reboot bootloader.
4) Open ADB (while phone is still in fastboot mode) and type fastboot flash recovery twrp.img (after downloading the TWRP image, renaming it and moving it to my ADB root folder. I am using TWRP 2.8.0.1 here.)
5) Type fastboot reboot
6) After the phone restarts, type adb reboot recovery. TWRP runs for me. Power+Home+Volume Down (3 button combo) also works now. (Previously this would reset the phone.)

Hey Man, im glad it worked. I could use your help.
I bricked my phone and need the restore file, Do you think you could make a backup from TWRP and upload it?
I would be super grateful.
Thank you.
Here is a zip with CM11, twrp 3.0.2.0 and Gapps for CM11.
Its the best rom I found.

Hi. What is your "brick" like? Does your TWRP still run? If yes you can just copy a custom OS into your Microsd card and install it from your Microsd.
You can also use ADB push to move files from your PC to the phone.

Sent from my MT2L03 using XDA-Developers mobile app
If you TWRP doesn't run, you need to install that first. Do steps 3 and 4 in the above post to boot into bootloader and install TWRP.
3) Restart, hold down power + home to boot to the fastboot. Or in ADB type adb reboot bootloader.
4) Open ADB (while phone is still in fastboot mode) and type fastboot flash recovery twrp.img (after downloading the TWRP image, renaming it and moving it to my ADB root folder. I am using TWRP 2.8.0.1 here.)

The Ultimate guide to flash and root Xperia L (aka, taoshan)

This thread will guide you to flash a custom recovery, Root the device, flash custom ROMs. Firstly, read the entire post and then start your work.
I am a noob. But I have a little experience of rooting and flashing. This device gave me nightmares which are less than as compared to the Xperia Sola which I bricked some years back.
My device has a problem. It does not help install twrp with the traditional ways we know like we can see in the Official TWRP website using "dd" method, the Cyanogenmod link using fastboot commands, the Flashify method, the RecoveryApp method whose apk I never found and the Recovery Installer Utility.
I came to know that either my phone don't have the recovery partition or the phone is overriding all the commands.
Using fastboot commands would give the error like in this post.
Using Flashify would tell me there's no recovery partition found. Rashr would complete the flash process but after booting to recovery, there was no TWRP, just the stock Android recovery.
If you read carefully on the twrp page of XL, there's a line which caught my attention late enough.
It means that TWRP may not work on your device unless you install other custom software as well.

Flashing custom kernels with flashtool is easy and they come with recovery pre-installed and lots of amazing stuff, but they won't do any good with the stock ROM. I've tried the Extended stock kernel, the Phantom Kernel and the Thunderzap 4.15.
After surfing the web and forums of other devices, I found that there is a chance I can fix things by updating/repairing software via PC Companion. But something happened and repair also failed.
I can't tell the reason why this happened. And I didn't store the logs. But with trial and error I found some workarounds.
Actual Methods start here
Rooting the device
If you only want to root your device for various reasons, then you will need nothing but a Rootkit. Check out this post about Rooting Xperia L.
But if you are planning to install custom ROMs for your device, then skip this rooting step. It won't be necessary for this condition.
Flashing custom recovery
*Try this method only if above-mentioned method fails*
1. Download TWRP 3.2.1 img. The 3.2.2 and 3.2.3 versions work perfectly but they caused the screen to flicker like hell on my device. Rename the file to 'twrp.img'
2. Download and install adb and fastboot drivers system-wide.
3. Connect your device to PC via USB cable and enabling USB-debugging mode.
4. Open Windows Powershell/Command Prompt in the twrp download directory by pressing Shift and clicking right mouse button.
5. Use fastboot command on stock ROM without root and Unlocked Bootloader. Instead of flashing twrp image to recovery, flash to boot. Use the code:
Code:
adb devices
adb reboot fastboot
Wait for device to boot into fastboot mode. A blue LED will flash when connected.​
Code:
fastboot flash boot twrp.img
fastboot reboot
After reboot, don't boot to system. Boot to recovery by pressing volume up repeatedly when pink LED glows. Stop when device vibrates and LED color changes
Flashing custom ROMs
Once the recovery is installed, everything becomes easy. you can find different custom ROMs on the device page here on XDA.
My favorite one is The resurrection Remix Nougat. It is stable enough to be your daily driver. You can head to that page and follow their instructions. But I will also provide steps here.
When in TWRP after the last step, move the downloaded zip file of the ROM and GApps you want to install to the storage of the device by simply connecting via USB.
After that, in TWRP click on Wipe->Advanced->Tick on System, Cache, Dalvik cache. Then Do swipe to begin wipe.
After wipe, go back to main menu. Tap on install, select from the list the ROM zip. then tap on Add more zips and select the GApps zip and then Swipe to start flashing.
After flashing, reboot to system. The first boot takes time. Don't panic if it won't boot.
Install TWRP to FOTAKernel
After booting to your new ROM, you can install the TWRP to your FOTAKernel.
This can be done as following:
Get the downloaded TWRP img file and push it to the device using command line. Open command prompt in the TWRP directory and type,
Code:
adb root
adb wait-for-device
adb push twrp.img /tmp/twrp.img
Now extract the TWRP image to the FOTA partition code,
Code:
adb shell dd if=/tmp/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel
Now reboot to recovery
Code:
adb reboot recovery
Note that custom ROMs often come with Root access inbuilt. If your ROM happened to be not, and your ROM is based on Lollipop or later version of Android, you can root with Magisk. Just read carefully before proceeding.
Comments are welcome!

Hi.
I'm following this thread and I'm stuck on the fifth step "... flash to boot. Use the code:
adb devices​adb reboot fastboot "​
I think my Sony Xperia L C2105 does not have the fastboot mode.
Here's what I did:
Drivers for Xpleria L are installed.
The bootloader is unlocked (I think!)
1 - installed 15-second ADB
2 - open Windows power shell
3 - Command: adb devices
Response is: "List of devices attached: ZH8001ADB3 device"​
4 - Command: adb reboot fastboot
Response is: long pause, phone booted but in normal mode, and light is red ...!​
5 - Command: fastboot flash boot twrp.img;
Response is: "<waiting for device>";
- phone still running in normal mode and the light is red.
- few minutes later, the phone is charging with green light present.​
I think the phone is rooted.
I used the code provided by the Sony website to unlock the bootloader.
Using the Root Checker Basic app, I get the info: "Congratulations! Root access is properly installed on this device!"
But if I type in the dialer *#*#7378423#*#*, and go to Service info > Configuration > Rooting status is "Boootloader unlock allowed" !!
Is that why it does not work?
I tried switching it off and doing Boot into Xperia L Fastboot Mode Using HARDWARE BUTTONS, but the phone is dark, with no picture, and the led turns blue.
Using the command:
PS C: \ adb> adb devices
List of devices attached
PS C: \ adb>
I've been trying to do that for a few days now and I still have not managed it, even using other advice.
Can someone tell me what to do?
Thank you in advance.

1. When in fastboot mode, you should type in cmd "fastboot devices" to check the device connectivity. If you can't, then connect using hardware keys.
2. Blue light indicates that you are in fastboot mode. If list of attached devices are blank, that means drivers are not installed (properly). Connect your phone again in fastboot mode and check your drivers page, Win+X > M (I am assuming you must be on windows). There must be a tiny yellow triangle on your device's name. Right click on it and uninstall it and remove device. Try again installing drivers from the flashtool's folder. Disable driver signature enforcement if you are having trouble going the straight way.
3. Your bootloader is still locked because if it had unlocked then the message displayed would have been, "Bootloader Unlocked: Yes" or something like that. Try flashing your stock ROM via Flashtool. Wipe cache and data while flashing. After flashing stock Rom, try unlocking bootloader again. I believe you are using Flashtool.
4. If you are rooted, then you must have any SuperSU app installed on your device. And it's all good even if you are rooted.

Tough one! Try this. It will wipe your data partition, though.
If it will let you, power down the tablet for about 10mins. Then boot into TWRP. Go to "Wipe" and swipe for Data/Factory Reset. Reboot.
If the M10 still won't boot, in TWRP re-format Data (by typing 'yes' under Wipe->Format Data), and wipe cache and Dalvik Cache. I think dalvik is under Wipe->Advanced. Factory reset again. Reboot.
As an absolute last resort, you might try fixing permissions in TWRP under "Advanced". But I don't think that's going to do much, because you haven't booted the ROM successfully yet.
Hope one of these works for you. Let us know what worked for you. If nothing works, PM me and we'll try some other things.

I followed the instructions but on the last step of rebooting to system the device restarts, shows the Lenovo logo then it goes to a black / blanks screen. It appears to have shut down. I must hold the power button for several seconds before it wakes up (or restarts?) and does this all over again -- shows the Lenovo logo then black screen.
For the record the device was already rooted with Magisk. I was just trying to do a TWRP backup but found /data mounting errors so tried following steps 6 & 7. At the moment the device refuses to boot up. I am unable to get back into Recovery Mode. The ONLY thing i can do is get into FASTBOOT mode and issue commands from CLI.
The following hardware key combos produce the same results -- tablet turns on to show the Lenovo logo, after a few seconds the screen goes black (the device appears to have turned off):
x Power key
x Power Key + Volume Down
x Power Key + Volume Up
x Power Key + Volume Up + Volume Down
** Release of keys is done once Lenovo logo appears
Any ideas?
UPDATE
I went ahead and performed: fastboot flash boot boot.img << the boot.img was the earlier patched magisk image i used to get the rooted working tablet.
After performing the above the tablet turned on and is now showing the Lenovo logo however it does nothing else --- it remains on the logo forever. I am able to get into TWRP recovery. I went ahead and wiped Dalvik, Cache, and Data. Rebooted to System but still it is stuck on the Lenovo Logo.
The device if fully charged.

You could try recovering the tablet with LMSA. See this post. You'll lose all your existing data and setup on the tablet, though.
Not sure what went wrong for you. Do you have a TB-X605F with Snapdragon 450 SOC? The existing TWRP is only for the SDA450. I'm working on one for the M10s with SDA429.

Not sure what went wrong for you. Do you have a TB-X605F with Snapdragon 450 SOC? The existing TWRP is only for the SDA450. I'm working on one for the M10s with SDA429.

Thanks for the response. Yes mine has the Snapdragon 450. I will investigate the LMSA. Been messing around all day but made no progress -- not even QPST is working out.
