HI everyone,
I updated "successfully" from Kitkat to 5.0.2 on my rooted (stock ROM) Nexus 7 second gen.
Unfortunately, when I tried to upgrade to 5.1 everything seem to be normal until the device rebooted and it went through the "update process". 3/4 the way through, the green droid went on his back and the "ERROR" message appeared.
I wiped the cache partition but that doesn't help. I tried to download the update in safe mode, but no success. I also find it odd that each time I reboot my device, I get a message from Android that it is "updating my apps".
If I didn't have any apps and a lot of data on my Nexus, I would wipe the device clean but I'd rather avoid this, if at all possible.
Is there a way to upgrade to 5.1 or reinstall 5.0.2 without losing everything?
Thanks

No problem. As you rooted it before then presumably it is unlocked and equipped with custom recovery, so all you have to do is:
boot TWRP
connect PC
transfer data and APKs to PC
flash OS
If you don't have TWRP installed, then boot it like this fastboot boot twrp-3.0.2-0-flo.img

Hi,
Thanks for the reply. I rooted with Kingroot. I don't believe I have a custom recovery. The bootloader is locked as shown when I boot into recovery mode.
I want to avoid transferring my data and APK files to my PC.
Should I assume there is no way of reinstalling the OS without wiping out the device?Also, there is no link in the above quote: fastboot boot twrp-3.0.2-0-flo.img
Since I got no other replies, I went and restored to factory image. I do have another question. I hope I get a better response there: http://forum.xda-developers.com/nex...a/nexus-7-2013-wifi-root-marshmallow-t3515072
Thanks for the reply.
Can we compare using fastboot flashing TWRP vs Nexus Root Tool Kit: http://www.wugfresh.com/nrt/? I ended up using this utility instead because it was pretty much one click and it didn't require command lines and for whatever reason, I found instructions using fastboot a bit confusing. Which method is better or has more advantages? I left my bootloader unlocked.
Incidentally, I think there was something wrong with my Nexus image. As a result, I did use Google's instructions on how to flash etc. the OEM image. Instructions weren't ideal but I managed to figure things out: https://developers.google.com/android/images
The instructions are here which I assume would be similar if I wanted to fastboot TWRP?
To flash a system image:
Download the appropriate system image for your device below, then unzip it to a safe directory.
Connect your device to your computer over USB.
Start the device in fastboot mode with one of the following methods:
Using the adb tool: With the device powered on, execute:
adb reboot bootloader
Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device. For example, to put a Nexus 5 ("hammerhead") into fastboot mode, press and hold Volume Up + Volume Down + Power as the device begins booting up.
If necessary, unlock the device's bootloader by running:
fastboot flashing unlock
or, for older devices, run:
fastboot oem unlock
The target device will show you a confirmation screen. (This erases all data on the target device.)
Open a terminal and navigate to the unzipped system image directory.
Execute the flash-all script. This script installs the necessary bootloader, baseband firmware(s), and operating system.
Once the script finishes, your device reboots. You should now lock the bootloader for security:
Start the device in fastboot mode again, as described above.
Execute:
fastboot flashing lock
or, for older devices, run:
fastboot oem lock
Locking bootloader will wipe the data on some devices. After locking the bootloader, if you want to flash the device again, you must run fastboot oem unlock again, which will wipe the data.

Also, I could've sworn that when I rooted KitKat on my Nexus, my data wasn't wiped out. I don't recall doing anything to the bootloader. I can't recall which method I used, but I know for certain I didn't use the Nexus Root Toolkit. I should've recorded my steps when I rooted.
i rooted my nexus 7 using towel root on kitkat .. i unrooted using supersu... and ota untill marhsmallow with out a problem never use kingroot as its so un stable.

I have rooted my device using towel root which doesn't unlock the boot loader. I then used the twrp manager to install custom recovery. I am wondering how to restore everything back to factory as all the tutorials I have seen so far require an unlocked boot loader. Any help will be appreciated, thank you.

If I download a stock image from google and flash it from my nexus 7 using twrp will everything be restored to factory settings?
If the boot loader is locked does that mean I can just do a normal factory reset on the device and it will remove the recovery and root?

you have to install stock ROM by adb mode using fastboot command
you can't flash stock ROM via custom recovery.

Would you mind finding a link for me ? I have never encountered this before as I have always unlocked the bootloader to root but this time I used towel root which was different as explained above.
Doesn't the boot loader have to be unlocked to flash a ROM via adb?

nope,
Step 1: Download the ADB/Fastboot files and the
USB drivers for Windows based PC first. The the
latest factory image for your Nexus device can be
downloaded directly from Google’s website .
ADB/Fastboot – Mac , Windows
USB drivers for Windows
Extract the contents of the ADB/Fastboot ZIP file
inside a new folder called ‘google’ on your desktop.
Extract and transfer the contents of the factory
image inside this folder as well. The list of files will
include a ZIP file containing the codename of your
Android device, two files with “flash-all” names, and
a bootloader image file. All the extracted contents of
the factory image should be inside the same folder
as the ADB and Fastboot file, otherwise you will get
a file not found error.
Make sure to install the ADB drivers as well if you
are running a Windows based PC.
Step 2: Now, reboot your Nexus device in bootloader
mode. This is usually done by switching off the
device, and pressing the Volume down + Volume Up
+ Power button simultaneously. If that does not
work, try the Volume down + Power button
combination.
After the device has booted into bootloader mode,
connect it to your PC.
Step 3: Open a new Terminal or Command Prompt
window, and navigate to the ‘google’ folder that you
created in Step 1. Before we start flashing the
factory image, we need to make sure that your
Nexus device is being detected by the PC.
fastboot devices
If you are using a Mac, then you need to prefix a “./”
before every Fastboot command. So, the above
command will look something like this on a Mac -:
./fastboot devices
The above command should confirm if your device is
indeed being detected by your PC or not. If it is,
then proceed to the steps below. If not, repeat the
steps above again. Make sure that you have properly
installed the drivers and are inside the correct
folder.
If you are running Windows, copy-paste the following
command in the command prompt window -:
flash-all.bat
On a Mac, copy-paste the following command -:
./flash-all.sh
The script will then automatically flash the full
factory image on your Nexus device. Once the
factory image has been flashed, your device will
automatically reboot. Keep in mind that the first boot
might take some time so please be patient.
If the flash-all.sh script gives you a fastboot not
found error on your Mac, open up the file in Text Edit
and add a “./” before every fastboot command.
The flash-all script included in the factory image
might not work for all. It has always been pretty
unreliable and has only worked once for me in the
last 2 years. If you are in the same boat as me, you
will have to flash each partition manually on your
device. This is slightly cumbersome though.
The command to manually flash a partition via
fastboot is “fastboot flash partition filename.img”. In
the factory image that you extracted in Step 1, you
will notice there is another ZIP file. Extract the
contents of that ZIP file inside the ‘google’ folder.
Now, its time to manually flash the partitions to your
Nexus device. We will first begin with the bootloader.
fastboot flash bootloader filename.img
Then, we will flash all other partitions. They don’t
necessarily need to be in the same order as I have
listed them below. The names of the image files in
the factory image will clearly indicate the partition
they are intended for as well.
fastboot flash boot filename.img
fastboot flash radio filename.img
fastboot flash recovery filename.img
fastboot flash userdata filename.img
fastboot flash system filename.img
Thank you very much I will try this today.
I couldn't flash all and when I flashed the bootloader it came up with failed bootloader is locked?
Enter this command to unlock the bootloader:
fastboot oem unlock
After unlocking, you can run flash-all.bat (or run manual fastboot commands to flash).
Hello guys, a friend of mine has a galaxy nexus with some problems.
When I turn on the phone, it starts booting normally, but a few seconds after getting into "desktop" it starts popping up errors saying that the process as stopped.
I've already tried a few things, but without success. I'm running out of ideas and here I'm asking for your help.
Things I've tried:
-Boot into recovery mode and wipe all data.
The phone says that the operation completed successfully, but after rebooting the phone remains the same. All apps, wallpaper, lock screen, etc. It seems that nothing was changed by this process.
-Flash a original google ROM
Following the tutorials, the first step is to unlock the bootloader with fastboot oem unlock. The phone shows a confirmation asking if I want to unlock it, I say yes, and it shows "status: unlocked". But after rebooting the phone it is locked again!!!
I tried to flash the room without rebooting the phone after unlocking it,
Code:
fastboot flash bootloader bootloader-maguro-primela03.img
fastboot reboot-bootloader
sleep 5
fastboot flash radio radio-maguro-i9250xxla02.img
fastboot reboot-bootloader
sleep 5
fastboot -w update image-takju-imm76i.zip
The first command to flash the bootloader also says that completes successfully, but when I'm flashing the radio it will complain saying that the phone has the wrong bootloader version installed.
-Flashing via Odin
It fails when is flashing system.img to the phone
-Flash custom recovery - fastboot flash recovery recovery.img
The process completes "successfully" but when I boot into recovery mode, there is the original one and not the one I just flashed.
-emmc brickbug - partition scanner
I found this thread http://forum.xda-developers.com/showthread.php?t=1823918 and tried to run the partition scanner. As I can't have the phone on enough time to use adb shell, I tried to use this scanner via adb sideload but the phones returns an error when running it. (probably because it doesn't have busybox installed, not sure)
After trying all of steps above, the phone is still the same... nothing changed. Once, I managed to connect it to the pc as an usb storage device, and was able to copy some photos from the phone and deleted them. But after rebooting they were all there again. It seems that all write changes are not persistent.
I'm out of ideas now... Do you have any idea of what is the problem? Or any suggestion for me to try?
Thanks in advance
I believe that there is a script in the android SDK tools called flashall.bat which will reflash the kernel, bootloader, recovery, ROM ect. I'm not sure how to use it, but you could potentially try that
Hi, thanks for you suggestion, but unfortunately it didn't work.
I had a look at the flashall.bat script and it runs the same commands I run manually.
I think that the phone might have some hardware problem... Normally I would buy a new phone, but I'm trying to fix it because it is important for my friend and for me because it is challenging.
I guess that the next thing I will try, will be trying to run emmc_find_brick script by @hg42 via sideload
Try formatting /system and reinstall android. Power your device into bootloader mode. Make sure your device is unlocked. Also, make sure you have the factory image downloaded. After your device is plugged in into your computer, use this fastboot command: fastboot erase system. This will delete everything from /system. Also format /data and /cache: fastboot erase data and fastboot erase cache. After that, try installing the factory image again.
Hello all,
I have Zenfone 2 on which I intended to use a custom ROM.
So the first thing was to unlock the bootloader.
On previous occasion, on my Nexus, I had used the - fastboot oem unlock - command and it had worked. So with that in mind, I booted into the bootloader and tried the command, but it failed - saying oem command unrecognized.
Then I searched online and apparently, to unlock the bootloader, Asus has launched an app! But to be able to install the app, I need to get a normal boot happening, which is not happening now.
In between all this, I tried the commands - fastboot flash recovery <recovery.img>, fastboot flash boot <boot.img> too. But none of these were successful, and each of them returned a 'Permission denied' message, probably coz the bootloader was locked.
Now the situation is that -
- Bootloader is locked.
- Phone is stuck in bootloader
- There is no recovery installed. In fact, from the bootloader, when I try to boot into 'Recovery Mode', it goes there for a second and returns back to the bootloader. Doesn't show the normal android image with a 'X' on top.
- There is no root access.
Now I think the first step is to get root access, and for this I want to try the method with installing CWM recovery and SuperSu.
But for this, I need to be able to push the SuperSu.zip to the phone, which I am not able to.
Can somebody please help!
r the drivers for fastboot & adb update to date?
Android version?
If the phone is stuck in bootloader, you can use Asus Flash Tool to flash .raw files and unbrick the phone.
Raw files: https://yadi.sk/d/FijRoAVJtvRiG
AFT: https://yadi.sk/d/NQCiY--IsQjBr (I use AsusFlashToolInstaller1.0.0.14.exe).

Hello, I have sent my phone to warranty and after that I received a phone with NO RPMB and after many frustrations I found (with help of many users and forums) how to workaround this..
To start:
Download boot image from here
Download twrp from the official website
Change the name to boot.img and twrp.img and put it in the platform-tools folder
Open the terminal there
Download your favourite rom
Enter fastboot mode on your phone
!!!!After this you will loose all of your data!!!!
Paste this to the terminal
fastboot oem unlock
(select yes on your phone)
fastboot flash boot boot.img
fastboot flash recovery twrp.img
fastboot format userdata
fastboot format cache
Reboot to recovery (if it doesn't enter at the first time enter download mode again and restart to recovery)
After that you have twrp and can flash every rom.. yay!!!
Wipe everything.
Copy the rom zip to your phone using MTP
Install your fancy new rom
If you want to install magisk:
Install the magisk manager.
On the app select install and select patch image file. (it will create a new boot image already patched)
After that install the new image (patched_boot.img) using twrp
Do a clean instalation of your ROM (recomended) or a Factory Reset first
Reboot to twrp
Select install
Click in install image
Select patched_boot.img
Select install to boot partition
Reboot.
Install magisk manager and do the sugested setup.
You now have magisk working
Thanks to all the users that helped me!!
I had real trouble getting twrp to work the last time I tried this a few months ago. Followed the steps here and am now on pixel experience with magisk. Thanks!
Hello, im in the same situation of NO RPMB. This procedure will permanently lets have bootloader unlocked?
About Magisk, i can install it in usual way once im in the recovery? (I mean download latest stable version for Bullhead and flash via TWRP).
Thanks.

Click to expand...
Click to collapse
My bootloader is still unlocked after following this guide
For Magisk:
-Install your custom ROM and boot it up (without root)
-Then extract the boot.img from the ROM zip file and save it on your phone storage.
-Install the Magisk manager apk
-In Magisk manager, select install Magisk> choose the patch boot image option and -Select the boot.img you previously saved.
Once it's done, reboot into twrp and flash the patched boot.img. When you reboot Magisk will be working.
I've had no issues with my bootloader, even after an ota update for pixel experience.
Thank you, i will try it.
Another question. I never tried dowload mode before, as i read in other post i should Plug USB cable into pc, Hold volume up and power at the same time and plug phone into usb that's already connected to pc, right?
When in download mode i can fire up fastboot commands like im in bootloader mode?
So then after do last command fastboot format cache i can reboot to recovery from terminal using adb reboot recovery or i can / should do it from device?
About twrp it's ok to use the latest 3.2.3.0 official version or the 3.2.1 4core version from here as someone suggested from Reddit? https://forum.xda-developers.com/nexus-5x/development/recovery-twrp-3-2-1-4-core-t3796656

Power off your phone then press and hold volume - and power to enter bootloader, then connect to your pc and follow the steps in the OP
So i have to enter in bootloader mode? At point 6 of OP there is written to enter in the download mode, this makes me confusing.
Can anyone explain me latest 2 commands why they are needed?
fastboot format userdata
fastboot format cache

This thread is fairly comprehensive;
https://forum.xda-developers.com/nexus-5x/general/moto-nexus-5x-sticky-roll-t3207487
Holding volume - and power takes you to fastboot mode (download mode essentially), theres also an option to reboot into recovery (selectable using the volume keys.)
Formatting user data and cache is necessary prior to installing a new rom (especially if moving from stock). You lose all data (back up first!) But a clean flash is the best place to start.

Thanks for the explanation but for installing a new ROM usually you can do factory reset directly in TWRP, plus doing all the wipes, this should be enough.
About fastboot mode and download mode, they are completely different, fastboot mode: vol down + power, download mode for LG: Plug USB cable into pc, Hold volume up and power at the same time and plug phone into usb.
My question is what i can do in download mode? As OP says after entering download mode open terminal and use fastboot commands.

You need to use vol- and power to go into fastboot mode then connect to the pc. As for userdata and cache, if you don't clean them when coming from stock you will have issues (your data will be encrypted if you're on stock?). As I said this guide worked for me. The op was talking about fastboot mode in the 6th option (also there is much more information in the thread I linked above)
sorry for the confusing i wanted to say fastboot mode..
i knew the thread that you are saying but most people doesn't want to search so I made a little thread only with the needed parts..
I use it myself so I have a place to remember all the steps when I need to change the rom to a new one or when I make experiments and brick my phone XD
If anyone know anything else that should be in here just say, I really want to improve the post

your device will always be locked this is a workaround to get twrp, new roms and magisk while it stays locked..
with twrp usable it won't matter if you are locked or not

Thanks for the answer. You mean that now I have twrp, I can flash custom Roms with my bootloader locked without any issue?
Envoyé de mon ONEPLUS A3003 en utilisant Tapatalk
Yes if you have TWRP you can install custom ROMs, custom Kernel's, magisk, super su, etc..
the locked bootloader only prevents you from using fastboot commands like the one needed for installing custom recovery
Now that you have TWRP you can use it for everything
Hello everyone, I also have a nexus 5x with motherboard that has been replaced under warranty and unfortunately I can't keep the bootloader unlocked.
I tried the procedure you have indicated, but at this point there is the problem, because after inserting the boot.img and twrp.img inside the phone, then when I go to do the unlocking procedure with 'fastboot oem unlock (select yes on your phone) 'in practice the memory is deleted on the phone, so I lose the previously uploaded files, and therefore I can no longer continue with the flash procedure of boot.img and twrp.img because they are no longer present in memory.
I hope I made myself understood, maybe I am wrong, or is there a way to solve this problem?

fastboot is for the files on your PC not your phone
you need to put the files inside of platform-tools and then open cmd inside it and use the fastboot commands
fastboot will take the files of your PC
Hello, thank you for your information, since I haven't done modding on phones for a long time, I didn't remember exactly the procedure with fastboot and therefore I didn't understand where I had to put the files, but in the end I did it.
Thank you

Why is a custom boot image needed? I don't want to root.
Hello,
I hope this is the right section for this post.
I've been using a Note 8 Pro with zero issues until one week ago when I accidentally dropped the phone in the water.
After a few seconds submerged the display turned off and I felt an intense heat coming from the zone of the battery.
Having no chance to recover the phone (tried with Isopropyl Alcohol too) I decided to open it and manually dry/clean each component, having seen the situation inside gave me the phone is dead but I still want to recover some pictures/data from it.
Before opening the open Minitool was not detecting any device on my Windows Laptop, after cleaning each component Minitool is instead detecting the phone via USB, but I still can't extract any data because the "Usb debugging" option is not tuned on (and no the device is not rooted).
Is there any option to extract data from the phone? There's a way to turn on USB Debugging via ADB on a non-rooted phone?
Thanks,
Andrea.
how about trying your luck with a service ? most of the time they do have access to special programs, which have a better functionality than adb.
Thanks for the hint, but I am not happy with the idea of someone playing with my data
1. Try reboot phone to recovery
2. Connect it to your computer (download Platform-tools)
3. In the folder with Platform-tools open cmd
4. In cmd - adb shell
5. cd storage/emulated/0
6. ls
7. Now, using the commands, drag files from your phone to your PC
Thanks for your hint.
No luck so far, I think because the phone is not in recovery mode.
I can hear the phone starting up several times (hear the jingle) so I think it's in a reboot loop and I don't know how to boot it into recovery mode wo a working display (tried with power/volume up combination with no luck).
From the windows taskbar I can see that the phone is recognized for a few seconds before it restarts.
EDIT: trying to switch the phone on with the combination "power/volume down" brings to a kind of stable state and I can now see the phone in the windows taskbar recognized as a generic "android device". Still no luck when trying to access the phone as there's no device in windows and no device obtained through "adb devices" command.
EDIT1: I think that the phone is in "FASTBOOT" mode. If I type "fastboot devices" I can see it detected but still can't access it.
Any idea? Should I give up?
If it's popping up and down you need something to keep track.
You can try my UsbLog.exe (in the sig), it just sits there and shows what devices appear (if they have a driver) and disappear.
Try these to see if anything is working:
Code:
C:\>fastboot devices
C:\>fastboot getvar all
C:\>fastboot oem device-info
Yes it's popping up and down when it's booted in recovery mode whilst is stably connected when in fastboot mode but in this case I can't access the internal memory of the device.
I didn't get the purpose of logging the devices connecting to the USB as I can see the device connected for a while and correctly recognized as Redmi Note 8 pro but as it keeps popping out windows have no time to show it's folder.
As for the code you wrote: i will try asap but already tried with "fastboot devices" and I get the phone correctly listed but still can't access its memory as told.

After rebooting the phone in fastboot mode I can see it recognized as a generic android device from windows (still can't access the storage folder of the device).
fastboot devices----> I get the device listed with a series of numbers/letters
fastboot getvar all---> I get a list of information on token/token version/partition type and size/baseband/bootloader etc.
fastboot oem device-info----> FAILED (remote: unknown command)
So I think it's clear that the device is in Fastboot mode and instead is in a boot loop when started in revocery mode.
Is there a way to extract data from fastboot mode?
Thanks,
Andrea.
If you put a custom recovery on it in the first place you can try reflashing recovery from fastboot.
Fastboot doesn't allow you to read anything.
oem device-info is obviously an oem command that might not be on any device.
You've got a Mediatek processor. That has some low level equivalent to Qualcomm EDL, but I have no experience with that.
If you can get there you can download the user data partition, but it's probably encrypted. Also no experience with that.
The easiest is if you can get the system to mount/decrypt the partition.
You've tried the normal system too?
Is this A/B? Have you tried changing slots?
How much time does it stay up in recovery? Do you have ADB? Maybe try:
Code:
# stop recovery
Does that prevent it from looping?
So I should try to flash a custom recovery like TWRP for example?
What you mean with "normal system too"?
Changing slots you mean changing usb port?
It stays in recovery less than one second so I can't give any command via ADB.
EDIT: cant' flash any custom recovery because the bootloader is locked.
If I Try to unlock the bootloader via MiUnlock I get a warning saying that all data will be erased.
Any idea on how to unlock the bootloader wo wiping all the data?

My bootloader is unlocked!
Thank you very much.
Now I am going to try to flash a custom recovery mode via fastboot in order to access the internal memory of the phone.
EDIT: I've just flashed twrp-3.6.2_9-0-begonia.img but still can't boot into recovery mode.
Any hint on how to extract data from the system now?
You really want to boot the normal system because that's the best way to get decrypted data.
I realized that you don't have ADB enabled there.
You should look at B. Kerler's https://github.com/bkerler/mtkclient/
If you can pull the boot image off your device then I might be able to fix it so that you have ADB.
You'd have to flash it back in fastboot or mtkclient.
You can also pull a copy of userdata off the device with mtkclient.
As far as booting into recovery, there's a way.
Here's how, if you don't have A/B (that is you flashed TWRP into recovery and not recovery_a or recovery_b)
then you can fastboot flash a special file into the misc partition and it wil boot into recovery next reboot.
To return things to normal you have to flash the empty file to the misc partition.
Code:
C:\>fastboot flash misc misc-rec.img
C:\>fastboot reboot
Only do this if you don't have partitions that end in _a or _b
I really don't know if I have partitions A and B as you mentioned and I think there's no way to check actually.
I confirm I don't have "USB Debugging" active on the phone.
So if I understand correctly I should do the following:
- Flash misc-reg.img via Fastboot
- Boot into recovery just rebooting the system after flashing the above file;
- use MTKclient to dump userdata or boot image to enable ADB on (I will need help with mtkclient I suppose).
Is it correct?
EDIT: flashed TWRP first and misc-rec then rebooted via Fastboot/Reboot but nothing happens.

TWRP cant boot because you used wrong one. Search again in that unlock bootloader channel and use suitable one.

Hmmm, I am almost sure that the TWRP I've flashed was listed under Redmi Note 8 pro page. Can you please indicate more precisely where should I sera
EDIT: I think I've downloaded and flashed the correct TWRP file.
@Renate can you please detail your method so I can try to extract data from the phone?

1/Yeah it's official. You "flashed correct TWRP." Downgrade to Miui Android 9 (_9 in it's name) to boot into that TWRP and lose your data.
2/In unlock bootloader video above, search other video in his channel playlist and find TWRP video suitable for your Miui version.

Can't find the right video, can you kindly send me a link (I am on the latest Miui version and I am in Europe)?
In all the videos I've seen on his page he is using the device to install TWRP etc.
I think I just need the correct TWRP version for my MIUI release and then I'll flash TWRP and misc-reg.img. Is it right?
