[Q] Re-rooting

Im looking to re-root my N7 after upgrading to 4.1.2 and losing root. Ive managed to unlock my device but cant seem to do anything else as it gets stuck on "<waiting for device>" and ive tried restart bootloader etc but to no avail. Im using Ubuntu 12.10 and will be using the Terminal to try and re-root it. New to using the terminal so no sure as to what to do completely.
I'm also looking to downgrade the bootloader to the previous version so i can add CWM as a Recovery. Any help would be greatly appreciated.

Why are you using the terminal when there are good tools/one click solutions ??
is debuging on?

I find it amusing that your posts were six minutes apart. I hope that you find this helpful.

Id rather be able to root and unlock without using tools/one click solutions as they are not always the best on Linux and its more in the sport of android doing it yourself.

Maybe your version of fastboot is not exactly compatible with the bootloader, that's also why rooting is so hard. If able, try the windows version that comes with one of the Toolkits. Please, even if you don't want to, give it a try. Might make your life easier.
Edit: Try flashing the bootloader permanently, that's what I did, I just noticed you're trying to temporarily boot it.

[Q] Bricked Nexus 7

so my nexus 7 (original) was getting laggy so i tried reflashing the factory image. It wasn't working, so i downloaded the nexus root toolkit and tried flashing the stock ROM. It erases the boot, cache, system, etc, but it keeps getting stuck on the "sending bootloader" part. It just says:
sending 'bootloader' <2100 KB>...
what should i do? is it my computer? i really don't want a bricked nexus. please help...

Try flashing in boot loader
Type : flash fastboot boot boot.img
in C:\Andriod or path of the adb

no one help you - if you can not get access to fastboot - buy new nexus
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The solution here is at least in part not to use the toolkit so you can see for yourself what is going wrong. Download the appropriate factory image for your device and the Android platform tools, and then you can use fastboot to flash the relevant images over.
The bigger question is what state your device is in. Are you able to kick the machine into fastboot mode still?

I'm not "bullying" anyone, I'm pointing out that your post is based off of nothing but conjecture right now. If OP killed even fastboot then yes, his options are limited, but your post is inviting an even larger waste of time based on inadequate information-- which is exactly how these problems occur.

Solved
Thanks everyone. I got it to work. I should have mentioned that i did use flashboot initially but used the toolkit when it didn't work. In the end, I finally got fastboot to flash the image. Thanks again for replying.

where can I go for help?

Can someone suggest another forum where I can go for help?
The last 5 or 6 times I've posted questions here, I've gotten no answers at all. I really need help. My tablet was bricked because I lost ADB connection while updating the system partition. I know there is a way around this - I have a custom recovery and an unlocked bootloader - but I need help from someone who knows more than I do. No one here is going to help me, I know. Where do I go? Where can I find someone knowledgeable and helpful?

Have you tried booting to recovery from bootloader and regaining an ADB connection? This should be all you need.

I was updating my Nexus 10 tablet - had gotten to the system partition - when I lost the ADB connection. I've since learned that's a problem with newer Macs (I was connected to Windows through Parallels). Here's a link to a thread about that:
https://code.google.com/p/android/i...Stars Reporter Opened&groupby=&sort=&id=65301
Because of the lost connection, the system partition did not flash and my tablet is bricked. There is no operating system so it can't boot into Android, but it can boot into the Bootloader and Recovery mode. All the other partitions are fine.
I have a custom recovery (TWRP) and an unlocked bootloader, but I'm at a loss to figure out how to flash the system.img file. I can't boot to Android so I can't connect through ADB in Fastboot mode to flash the ordinary way. I am connected through ADB when I'm in Recovery mode, but I can't use the flash command in Recovery mode. Nor can I figure out a way to make TWRP flash the partition by running it as a zip file - mainly because I can't figure out what the update.zip file should consist of. There was an OTA update file on my device when I started the manual update (manual updates fail), but I didn't look at it and didn't save it.
I tried pushing the system.img file to the Nexus 10 using the Linux dd command, but that doesn't work with the system partition, which uses a special format. The details are explained here, but I don't fully understand it:
http://www.modaco.com/forums/topic/327661-how-to-backup-the-systemimg-bootimg-and-recoveryimg/
After spending about 8 hours on this last night, I believe the only way I can fix it is to create an update.zip file that uses a Linux script to flash the system partition, but this is way beyond my skill set and I can't find a model for how to do this anywhere. All tutorials I've found for creating zip files for flashing are for installing apps, not flashing a system partition - which is even more complicated than flashing, say, a boot partition. Nor can I find an update.zip file from someone's cache (sure wish I'd saved mine) to use as a model. I'm looking for someone with this kind of high level knowledge who can give me guidance - or someone who can refer me to someone who has this kind of knowledge.

I solved this problem.

Recover photos from nexus 6p bootloop

Ok, so I have nexus 6p that has entered into the dreaded bootloop right before i was able to upload my photos from my recent vacation. I am able to get into fastboot and recovery mode and was wondering if there is a way to get my photos off of it. I have been trying to use NRT pull command but it is giving me ABD Recovery device was not found. (phone is on bootloader) and I have no idea how to fix this. Any help would be greatly appreciated.
Edit:locked bootloader and no USB Debugging

Hello... What happened to your phone? Maybe it's yet time to fix your bootloop. Since you have access to recovery, it's not totally dead...
I guess you have the stock recovery?
Boot into recovery and select: apply update from ADB. From here, see if your device is recognized: ADB devices. Maybe you can try to pull your files from here. I'm not sure it will works, but worth to try!
Good luck...

Try:

Do you have a serial number displayed?
About adb pull, I'm not sure about the syntax, you'll have to find d it yourself.

BLOD is usually indicated when you have no recovery mode. Is your bootloader unlocked? Even if you are locked you can still apply an OTA and maybe fix your phone. Side loading an OTA will not wipe your data but may help recover your phone.

Bricked onn 10.1 with keyboard

So I bought one of those onn tablets from Walmart, went to flash phussons quack gsi for Q and whilst the system flashed fine via fastboot it refuses to actually boot (bootloop on the onn screen) I can't get into recovery either. Fastboot -w fails because it can't create an image for the userdata partition (when I go to manually format userdata it says the partition table doesn't exist.) I'm able to flash to the boot, recovery and system partitions no issue.

Android 10 roms I have tried do not work... I have the onn 8 and on 10 w/o keyboard.
Also I had no issues flashing android 9 roms on the 8 but on the 10 all roms have issues with no sound from the speakers but sound through wired & bluetooth headsets some roms have graphical issues some have bluetooth... but all seem to have sound problems... and some will not boot past boot animation.
Roms I got too boot were phh's 9, beast rom, bootleggers, bliss and liquid remix. Liquid remix runs the best so far... but on the 8 not the 10

I also tried the /e/ os gsi Wich is based on pie that didn't boot either, I'll try liquid remix
went to format system before flashing and heres the output i got
Invalid erase-block-size 0: must be a power of 2 and at least 4096.
Invalid logical-block-size 512: must be a power of 2 and at least 4096.
mke2fs 1.44.5 (15-Dec-2018)
/tmp/TemporaryFile-wirxYd: Unimplemented ext2 library function while setting up superblock
/usr/lib/android-sdk/platform-tools/mke2fs failed with status 1
mke2fs failed: 1
error: Cannot generate image for system
same type of error i was talking about with my userdata partition

What was your method for flashing?

Unlocked the bootloader with fastboot flashing unlock
Fastboot -u flash system /name/and/location/of/gsi
I had erased my system partitions before i flashed the gsi the first time and I think that's where I screwed up
If I could get into the recovery I'd just adb sideload the ota and start again

Be careful you don't lose your battery charge, it doesn't charge in fastboot, so it can be easy to get into a difficult situation with a battery below 30%
I can get you stock system, boot and recovery images for your model later this evening.

Alright, thank you and I've already been attempting to use your back up images of stock off xda to try and restore it is there anything special I need to do or are you going to get like a flashall file made?

I am going to get the system and vendor partitions from the ONA19TB007 uploaded (currently only have boot and recovery)
Once those are up, you should be able to flash them via fastboot.

The speed is by server. Quebec seems to be fast for me most the time. If there is It's there decryption on twrp? I have been happy with stock personally but if you need any more images let me know. Also let me what way you want them. I can flash then use twrp or use dd commands but I would need to know what dd you wanted. I don't have sptools installed right now though. I could probably get it working on my Mac os if needed be though since I have many of the Linux libraries/services. Last option would take the longest since it's actually learning new cli commands. I am kind of a slacker but if someone has a bricked device then... I want to help.

I figured out its my stupid internet connection at home... apparently, while my download speed is great, my upload speed could be outpaced by a burro carrying floppy disks

Not hard bricked by a long shot.
Several of us have recovered from this scenario.
Somewhere around here I posted a link to a xda thread with a similar situation that can happen with some HTC phones. Basically, you build a script to constantly reboot it into fastboot.

everytime i try to boot into fastboot mode it reboots it doesnt go into fastboot mode, is this because the battery life is low and does not want to boot into fastboot mode? Also how would i charge my device it keeps flashing on the low battery icon. any help would be appreciated also a link to your post would help me greatly.
