[Q] Can't use su, can't turn on root. All I want is a full wipe.

Hello.
The screen of my toro is completely destroyed. It's shattered and the ribbon cable is torn, so no touch input and no image. The rest of the hardware is in tact and working perfectly fine. I want to sell this for parts, but want to wipe all of my personal data before doing so.
I'm running CM10. Using su in ABD, as expected, says "Permission denied" because root is not enabled in developer settings. I cannot enable this using the touch screen because it does not work at all. I figure I can plug in an OTG keyboard and count my key presses, or similarly boot into recovery and count my clicks of the volume rocker.
But once I'm here I'm not entirely sure what to do honestly. Is there a CWM installable package that resets everything to factory settings? I emptied the sdcard directory from ADB but I'm afraid personal information exists elsewhere on the device as well.
Any help here would be appreciated.
Thanks!

you could fastboot the images as you do not need the touchscreen to do so.

Thank you for your help. I've never used fastboot before.
I ran:
Code:
adb reboot bootloader
and waited for several minutes. Then:
Code:
fastboot devices
and no devices are detected. ADB detects my phone when I boot normally.

I'm in Ubuntu, I didn't understand how fastboot worked and downloaded a precompiled binary without realizing I already had it in my platform-tools folder... pretty stupid.
I used fastboot to erase each partition individually with:

[Q] please help

i'm having bootloop after installing 17/02/2013 CM10.1 rom on my gsm gnex. the issues are:
1. i don't have any previous working cm10 rom saved in phone's sdcard.
2. can't get adb working, maybe because i never enabled usb debugging mode before.
fyi, i have never flashed any other roms, just CM roms. please assist..

Go into recovery and transfer a new Rom download to your phone if you have a computer. There is an option to transfer files inside recovery.

that requires adb (adb_sideload- correct me if i'm wrong).. my adb is not working.. can't boot to android.. can't find a way to enable usb debugging mode.. so no adb..

Do you have a custom recovery or experience with fastboot? Boot a recovery image via "fastboot boot recoveryname*.img", and adb is enabled.

Attached is clockworkmod touch recovery for gsm galaxy nexus, maguro. Phone in bootloader mode, open a terminal, cd to directory of fastboot and where you move this file to, type fastboot devices to verify device is connected, then "fastboot boot CWMT6023.img", without the quotes of course. This will temporarily allow you to use clockworkmod recovery, and thus adb, without having it on your device once you have selected "reboot now".
And if that didn't help, try consulting http://forum.xda-developers.com/showthread.php?t=1626895, since i'm thinking you haven't used fastboot in a terminal, but only know it's 'mode', and may need help with drivers.
You also might want to consider just straight out flashing cwm recovery, since YOU NEED TO MAKE BACKUPS!

sorry, i got cwm. but what does fastboot have to do with cwm? i can't use cwm to restore because files can't be sent from computer to it.
as of fastboot in terminal, it seems the phone not connected to computer. is there anything has to do with my drivers? "fastboot device" command shows <waiting for device>

I gave you that link to set up drivers more than anything else. If you already have cwm, boot to it and now you can adb push a rom.zip to your sdcard and install it, wipe caches and perhaps a factory reset [if you're changing to a different rom], OR, you can first try and wipe cache and advanced, dalvik cache to see if that fixes the bootloop.

1. Why didn't you make a backup?
2. Why didn't you make sure you know how to get out of this situation before flashing new ROMs?
3. Search as there are LOTS of tutorials on how to use adb to side load a new ROM via CWM

If you think that then you have no idea on how adb works...
That is ONLY applicable when Android is running. As it's not, it's irrelevant...

ADB should work in your custom recovery regardless of USB debugging being enabled or disabled.
I can't tell you how many times I have rebooted into recovery, wiped, then realized I forgot to put a file on my sdcard that I wanted to flash. I then use adb to push the file(s) from within the recovery.
Edit: I really need to refresh prior to responding.

so i can't get adb working because of the driver? thats why i got "waiting for device" when pushing file to phone?
edit: i've installed all the required drivers, it's not my 1st time doing it. MAYBE, this computer never connected to my gnex before, as i've formatted it a few days ago. So the gnex driver was not properly installed.. Is it possible?

If that version of cm 10 is for 4.2.2., then i think you may have an issue accessing adb without first getting the rsa verification, even in recovery (but im not sure). Looks like your only other option would be to fastboot flash stock images. And of course it sounds like driver issues, especially if your fastboot is not even working. Again, that link I posted will get you back up and running. http://forum.xda-developers.com/showthread.php?t=1626895

Nexus 7 - 2nd gen: update failed to Lollipop 5.1

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.

Note 4 Verizon (SM-N910V) stock boot loop

I need some help. It seems like I am in a circular conundrum and have tried almost everything. A quick summary of how far I've gone (and searched): gone as far as successfully performing a stock reflash, but the boot loop is still there. I realize this could be a hard failure, but even so, shouldn't there be a log stored somewhere to tell me what failed?
An abbreviated list of things I've tried (many times w/ varying parameters where possible):
- wipe cache
- factory data reset
- reflash stock using ODIN
- flash TWRP (failed: Complete(Write) operation failed)
Here's what I CAN do: boot into download mode, connect with ODIN, boot into recovery mode.
Here's where I get into some circular issues. The next thing to try was unlocking, rooting and installing a custom ROM.
Any of those things seems to require being able to boot or have USB debugging enabled. So to summarize my last known configuration:
(1) USB debugging apparently disabled
(2) Samsung reactivation lock enabled
(3) Encryption probably enabled
So how do I get a custom ROM installed with all these not in my favor?
Unlock bootloader: root and/or adb push access required.
--> I can't adb push because USB debugging disabled.
--> I probably can't adb push to that location/chmod because I don't have root
--> I can't root because it seems all the root methods require a booting device to start with
I CAN/should be able to adb sideload (I have been able to get the device to show up with adb via going into stock recovery then apply update with adb, but not sure what to sideload)
Thanks in advance for any help you can provide!

You'll definitely have to get your device booted in order to root / unlock your bootloader. You need su permission during the adb part of the unlock process which is where the temp root from kingroot comes in to play. I would recommend trying to download and install the full official firmware of BPA1 and flash it in Odin. You won't be able to flash TWRP or anything else until you get your bootloader unlocked and that will require you to be on the BPA1 firmware. So that's where I would start.

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?

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.
