Flashing bootloader without a computer(rooted)

I've downloaded redbend_ua and the clockwork recovery image. They're both currently on my sdcard's root. I'm trying to copy redbend_ua, but there's no 'cp' command???
I've been a Linux SysAdmin for over 5 years, so I'm comfortable on the command line. Where's cp? Is there an easy way to install bash 3?

I can't link the post with tapatalk, but detailed instructions are in a post labeled "Clockwork recovery no computer method"
By default the cp command isn't included in android... it is included in busybox. There is an app on the market, and the one click roots install it by default. Without busybox the cat command is used as so: cat > .

Wow... I'm embarrassed I didn't try that. I'm usually against piping cats but sfobv that's what is needed.

Adb:command not found ubuntu

I got a new nexus 7 to day and I'm trying to install cwm and when I try to Adb terminal gives Adb command not found. Help please?

Did you install the Android SDK on your PC first? There are other sources of ADB, too. ADB is not built in on Ubuntu. Or, are you doing this on your N7?

I have all that installed. I have the Adb file and the fast boot file and I cd'd to them and when I try to use the "Adb reboot bootloader" command I get Adb command not recognized.

Are you actually using a capital A as in Adb? That would not work.

No that's just how my phone is correcting it.

Just remembered something... adb is a 32-bit app. You need to install a 32-bit library on a 64-bit machine to get it to run. Can't remember the name off the top of my head...will try to find it.

sudo apt-get install ia32-libs ... see if that works for you...it will take a while to install.

Okay, I'll try that when I can. Thanks. Is there a way for me to mount my n7 on here as mtp?

Have had no luck with MTP on Ubuntu myself. To get files to my N7 without adb, I either use a USB stick with an OTG cable or the AirDroid app.

I'd try some kind of cloud storage but I don't have Internet access which makes things that much harder.

I feel for you as I am in the same boat much of the time. Makes life hard.

Try "./adb ...." etc
Otherwise you will need to "chmod +x adb", then try the above.
Good luck!

./adb worked! Thank you.

[Q] Dropped phone, touch screen not working. Extract photos and/or wipe device?

I dropped my N4 today. The screen cracked, and most of the touchscreen is not responsive (the screen image appears fine). My device is protected with a numeric PIN.
1. Any ideas on how to recover data (specifically photos) from the device. The device connects to my PC via USB, but I can't view the drive contents without entering the PIN, and I can't enter the PIN because the touchscreen doesn't work.
2. Second, I'd like to wipe the device, again without using the touchscreen. I'm assuming I can do this with the Nexus Root Kit and/or ADB/Fastboot commands.
Any advice, particularly on (1) above, would be greatly appreciated!

Hmm..

Well, i cant say I have tried to do this with a locked phone, but you should be able to do everything from your computer. and through adb, and fastboot.
For example to get ADB installed on your computer follow this quick guide: http://www.addictivetips.com/mobile/...ll-it-android/
and once that is done then open up "Command Prompt" if you are using Linux it would be the "terminal"
then navigate to the folder that has the files in it. To navigate you want to use simple commands like cd.. and cd Name_of_folder. "cd.." means go back to the previous directory. And for "Cd Name_of_folder" Means you want to go to the folder "Name_of_folder , for example you are in c drive, and you are trying to go to a folder called "Cats" you would type "cd Cats" and then it would take you there. command prompt is uppercase sensitive btw.
So once you are in the folder that has adb, type "adb pull /sdcard/dcim" and that should pull your entire folder.
EDIT: also you need to be in recovery to do the adb pull correctly, to get there you can hold down the power button long enough for it to restart, and when it does hold both volume button at once.
Good luck.:good:
If it didnt work, let me know.

Great tips, thanks!
Unfortunately, while Windows is recognizing my device, ADB is not recognizing it. This may be because the device is locked, may be because the phone is set to MTP file transfer (for some reason, adb only recognizes my device when it's in PTP mode), or something else altogether.

Same deal, adb won't recognize device from recovery, either, even though Win7 Device Manager shows Android Phone | Google Nexus 4 BootLoader Interface as one of my devices.

Well then you will need to install the adb drivers, I'll give you a link in a minute

Hello?

I already have these drivers installed. Still, adb won't recognize the device when the device is booted up, and won't recognize the device when in recovery mode.

So, when your phone is in recovery, and plugged in, in device manager does it show a "?" Or something near the icon of the phone?

Device manager shows it as attached when in recovery mode.

Hmm, I think you might be in bootloader? What does it look like on your screen?

You're right! I booted into recovery, and now adb recognizes my device! I pulled all SD card contents to my PC, which includes the photos I was trying to save.
Thanks so much for the help, and sorry for being dense; your first post should have been enough to get me through this.

Root & Install TWRP H830 (20A) (Nougat) LG G5. Hard Recowvery Method

Hi guys, I didnt have much luck with the Easy Recowvery method on my G5 (20A)
Sooo, i thought i'd share with you, (what i like to call) Hard Recowvery method.
This is the most effective way i've rooted & installed TWRP my H830 on 7.0 (Nougat)
First lets download the neccessary recowvery files located here (Put them all in a folder): https://build.nethunter.com/android-tools/dirtycow/arm64/
Make sure you have the latest twrp for your phone: https://twrp.me/devices/lgg5h830.html
Latest Verity zip: https://build.nethunter.com/android-tools/no-verity-opt-encrypt/
Latest SuperSU: https://download.chainfire.eu/1021/SuperSU/SR3-SuperSU-v2.79-SR3-20170114223742.zip
---
Shift+Open Command window in Recowvery folder
Note: Use app_process32 on 32-bit targets.
once in cmd window from your recowvery folder follow these steps:
---
adb push dirtycow /data/local/tmp
adb push recowvery-applypatch /data/local/tmp
adb push recowvery-app_process64 /data/local/tmp
adb push recowvery-run-as /data/local/tmp
adb shell
$ cd /data/local/tmp
$ chmod 0777 *
$ ./dirtycow /system/bin/applypatch recowvery-applypatch
"<wait for completion>"
$ ./dirtycow /system/bin/app_process64 recowvery-app_process64
"<wait for completion, your phone will look like it's crashing>"
$ exit
adb logcat -s recowvery
"<wait for it to tell you it was successful>"
"[CTRL+C]"
adb shell reboot recovery
"<wait for phone to boot up again, your recovery will be reflashed to stock>"
adb shell
$ getenforce
"<it should say Permissive, adjust source and build for your device!>"
$ cd /data/local/tmp
$ ./dirtycow /system/bin/run-as recowvery-run-as
$ run-as exec ./recowvery-applypatch boot
"<wait for it to flash your boot image this time>"
$ run-as su
(You need to rename the twrp img to "twrp.img" and put in the root of your internal storage, OR you can use this adb push command. The next two steps wont be neccessary if already done so.)
adb push twrp-3.0.2-x-xxxx.img /sdcard/twrp.img
adb shell
run-as exec dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/recovery
"<wait for it to complete>"
$ reboot recovery
---
You should be in TWRP now,
flash supersu and the verity 4.1 zips. [Format Data] will remove internal storage encryption. so back up everything you need to with nandroid. lg backup, or titanium. (So i saw that they have updated verity zips but i just used 4.1)
I prefer lg backup, its easiest.
After you format data reflash supersu and verity zips for the hell of it. (you dont have to i dont think but i just did anyway)
Now just reboot, & enjoy
This isnt a method i created, i got it from this thread. and made the steps i felt were neccessary.

Just use the Automagically thread a few below this one. You have to be on 20A for it to work. I used that method and it worked on the first try. Now I'm on 20C and I'm rooted as well. This way is way too complicated.

First you need to run the script and follow the instructions to the letter. If you read into the thread you'll see that you need to turn off verification before you run it. I forget what option it is but ill check and post it for you. Worked smooth for me first try.

Stuck
I seem to be stuck at adb logcat -s recowvery
"<wait for it to tell you it was successful>"
"[CTRL+C]"
It's been a while. It hasn't moved from there and it won't let me input anything else. I got stuck after beginning of main and beginning of system.

Will this work starting from MM or only once on Nougat? My phone hasn't downloaded the update yet and it won't let me force it. Trying it on MM doesn't seem to complete.

Well this is interesting. The script the people above are talking about never worked for me. So I came here and got my hands dirty and did it the manual way. Everything worked great until I formatted data and reflashed verity and su zips. After booting, all I can get the phone to do is boot to twrp. I've successfully flashed the 20A kdz back to stock with unlocked bootloader. Just wondering what I did wrong?
Once I get into TWRP the steps used were:
1 - Flash SuperSU
2- Flash verity zip
3- Format Data
4- Flash SuperSU again (for good measure)
5- Flash verity zip again (for good measure)
All these instructions make sense but at the top of the OP it says to NOT swipe to allow system modifications. I thought after formatting data and flashing the verity zip that we can swipe to allow. If we can't modify the system partition, how do we access it for busybox, etc..
Sorry for the odd questions - just looking for clarity!
UPDATE: Sorry, I resolved my own problem. Just don't ever swipe to modify system in TWRP and you're good. Not sure why this was the case.

I figured out the issue. There are a bunch of threads floating around here that seem to think that the dirtycow exploit will work on 20A and 20C. That is definitely not the case. 20C it is patched so you have to KDZ back to 20A and then exploit. Then you can TWRP flash 20C if you want to go back to 20C.
I'm was on 20C though and dirtycow definitely doesn't work.
