[Q] [HELP] Bricked Galaxy Nexus (maguro)

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.

Tied everything to root swift, cant get past initial fastboot stage

hi all, sorry if this has beeen posted before but its bugging me as i spent literally 4-5 hours lastnight trying to sort it, i havee rooted 4-5 android phones in the past but im just having no luck with this one
i installed adb / fastboot minimal, enabled what needed to be enabled in developer options on the swift, booted the swift into fastboot mode, then when i run adb on my computer, the first command works 'fastboot oem unlock' but after that its constantly saying 'waiting for devices' whenever i try the next phase of commands ie. fastboot -i 0x2970 oem unlock-go etc it just wont detect the device at all in windows on adb, is there any suggestions anyone could throw out there before i end up sending it back and getting an alternative android phone thats easier to root? the only thing i can think off is its a usb driver issue? but i installed the gloogle usb drivers and it picks up the phone for file transfer etc so im not sure if this is the issue. many thanks!

Hi,
I had the same issue. When that happens, do commands without the -i 0x2970 bit. So for example:
fastboot -i 0x2970 erase recovery
becomes:
fastboot erase recovery
Hope this helps

I tried this but it still says 'waiting for any device' My initial command worked for fastboot oem unlock, but then I just couldnt do the following commands, and as a result whenever i tried to install a custom recovery / rom it gave me the error along the lines of 'unable to verify....'
edit: when i missed out the -i part, then said its already unlocked. however i still am not able to install supersu or the recovery as it still gives me the error 'signature verification failed'

Hi,
OK, what recovery are you trying to install? I would recommend TWRP 3.0.2 by Beroid (in the development section) because it's easy to use and it works. Get the image and put it in your adb folder is. Make sure you are in fastboot. Then run commands
- fastboot erase recovery
- fastboot flash recovery (name of file).img
Disconnect the device from your computer. Then remove the battery. Then replace the battery and press VOLUME DOWN and POWER to rebbot in to recovery mode to verify the installation.
You should now be in the recovery. You can flash custom roms and supersu within this new recovery.
Hope this helps

Bricked Xiaomi Mi 6

Hi,
I bricked my Xiaomi Mi 6.
My phone was bought in china, I unlocked bootloader and flashed global version.
Lately I flashed TWRP and Magisk.
Than I wanted to come back to stock and lock bootloader, so I flashed global ROM, everything was fine, stock recovery came back, so I used command "fastboot oem unlock" (I couldn't use Mi Flash, because it just stops working, when I'm trying to do anything). Than phone kept starting only to fastboot. I could also start phone to recovery, but not to system.
So, using MI Flash Unlock I unlocked bootloader again. And now I still can only enter to fastboot or recovery, not to system. And, my PC doesn't see the phone. I don't see the phone after typing adb devices to Command Prompt, also Mi Assistant doesn't see phone. I wiped everything through recovery, but it didn't help.
Please, help me with unbricking the phone. It doesn't need to be with locked bootloader or so, I just want phone to work...

I don't think it is bricked in fastboot the command should be fastboot devices not adb devices try that command
Hopefully someone here has more knowledge to help you sort it out.

You should format your userdata from fastboot that's why you can't boot into the system.
I suggest you to read this https://xiaomifirmware.com/downloads/download-install-drivers-xiaomi-mi6/ page before anything and then get XiaoMiFlash from that page, install it. It will also install fastboot and adb drivers for you.
Then I suggest you to use this https://forum.xda-developers.com/showthread.php?t=2317790 adb & fastboot tool since it's easy to use.
After getting miflash ready with the drivers and also the tool from the second link,
Reboot to fastboot and type
fastboot devices
After seeing your device type
format userdata
Then find a twrp image if you'd like to install any custom rom and install it from fastboot (you can find how to do it in their respective threads) or download miui from miui site then follow the instructions there go back to stock. But in case of the latter you may not to select lock bootloader option in miflashtool in case you may want to experiment with custom roms in the future.

Unable to flash TWRP

I am trying to flash the LineageOS on my Redmi Note 5 Pro (whyred). Initially, I used Windows 10 for the Xiaomi Unlock Tool. However, the Xiaomi Unlock Tool did not detect my device. So, I used this tool https://www.xiaomitool.com/V2/ to unlock my bootloader and it unlocked instantly. Now, I am using Ubuntu 21.04 (I am more comfortable using the command line here) (with android-tools-adb and android-tools-fastboot packages installed) to try to flash TWRP first.
When I connect my device, adb devices can recognise it. Then I use adb reboot bootloader to enter into fastboot. Now, fastboot devices can recognise it too. The screen of the phone shows the fastboot icon.
But, the problem comes here. I use fastboot flash recovery twrp.img and I get this error
FAILED (Write to device failed (No such device))
Click to expand...
Click to collapse
Now, when I use fastboot devices again. I don't see my device. Another change I see is press any key to shutdown written on the top left corner of the screen of my phone.
USB debugging, USB debugging security, OEM debugging are all enabled. Bootloader is unlocked (as I see in the settings). The phone is updated to latest MIUI version supported officially. And I used the same laptop and method to flash TWRP in a Redmi 3S (land) some time back.
(Posted the same question on android.stackexchange.com also) (https://android.stackexchange.com/questions/238996/redmi-note-5-pro-unable-to-flash-twrp)

Something else I experienced is that after randomly trying to get this right again and again, the command fastboot flash recovery twrp.img did not terminate or fail and got stuck.

So, this was a duplicate. I used the 5th method here and it worked for me. https://forum.xda-developers.com/t/everything-about-anti-roll-back-whyred.3816219/

Recovering data on a DEAD Redmi Note 8 PRO

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?
