forget the superboot.... i mean, if you don't mind to go for cyanogenmod ROM, the steps are very simple:
1) unlock bootloader
2) flash amon_ra (i think you have done that)
3) flash latest radio (i think you have done that too, otherwise, can obtain from cyanogen's thread)
3) flash cyanogenmod 5.0.3.1
4) flash google bits (can obtain from cyanogen's thread)
then you should be good to go.... i never used superboot, but then I am a heavy cyanogen fan, so that's all i needed
pm me if you need more help... i am however in China. here it is 10:16pm now, so i may be gone in an hour or so

by all means, you have to keep the "development mode" (= debugger) enabled at any time when working with customized roms

please tell me at what step are you right now? do you have amon_ra recovery? can you go into recovery?

hi there.
since this thread is in the totally wrong section of the forum (it should be in Nexus General, i am afraid it will be closed by the moderators soon.
so you can send me Private Message - i will try to help

Yes.
Now I have upgrade to ERE36B with amon ra, I have launch superboot and I have superpermission on Nexus but It not work.
I think I have to restore the Nexus to all original setting and rom (radio i think it's not important) and after do all update and rooting.
I think there is a problem that can be solved because I made only upgrade with Amon ra.

i don't understand why you want to stay with superboot... i never needed it.
to get root, just do this:
1) download the cyanogenmod rom (5.0.3.1) from the cyanogenmod thread
2) download the google apps from the same thread
3) put both on your sdcard
4) in amon_ra, flash cyanogenmod rom first
5) reboot
6) reboot into amon_ra recovery
7) in amon_ra, flash google apps
8) reboot
then you should be good to go and should have root
after that you can flash other roms, if you don't want to stay with cyanogen's rom

solved
1. this is related to roms not general.
2. its resolved, so its ok if anyone moves it.
3. superboot is very easy. no command line. just click install.
4. Best of all... PROBLEM SOLVED
For those of you still having trouble, before doing anything to technical, just boot to the recovery image and hit wipe device. then reinstall whatever rom.
worked like a charm for me.

also thanks to you all for quick responses. i got 6 in like ten minutes. here in texas, its like 9am on Sunday lol. I love xda.

are you the OP or is www1 the OP?
it seems like www1 still has the problem or not???
i agree, this is general, not development thread. but i am trying to help the OP.
i am sure superboot is a good tool, i just saw so many confused people at the beginning with it... and i never needed it, so

Sorry, I'm Italian and I can't speak english very well.
Not I try to flash with cyanogen mod to have the root (I hope) and after I reflash with standard rom.
I always do a wipe but the problem are not resolved.
I hope the mod can move this tread if is in the wrong section.
Thanks for the help.
So I think there are a permission problem.
ANyone can suggest how to manually install super boot? By insecure image boot for example.

More information would be nice. Did it just start doing that randomly or were you flashing something? Are you using a ROM or stock? If a ROM, which one?

Then I'm going to assume you haven't installed a ROM on it and are running the Stock OS that came with the device. What method did you use for rooting?

I misread your issue. I thought you said you rooted it and had issues. I have no idea why it would do that if you haven't even done anything to it. Devices just don't not boot unless you did something to mess it up or the device is broken. If anything try just booting into recovery and wipe cache. If that doesn't work try flashing the system.img found in the factory images using fastboot. Or flash all but userdata.img. There are tutorials around the web. But again, if you haven't rooted the device or done anything to the system files, I don't know why it's not booting. Hopefully the internals didn't go out on you.

I have never personally used this method, so I can't tell you what to do with 100% confidence. But if you can boot into the bootloader and then use fastboot to install TWRP recovery, there may be a way to pull files from your device using commands on your computer. You may have to do some research on that. Sorry I can't be more helpful. It's hard to know what's going on with your device when you haven't done anything to cause it.

Here's a link to their website for a download and instructions. But you need to have the android SDK installed. Do you have that at least?
https://twrp.me/devices/samsungnexus10.html
Please don't rush into anything and start flashing stuff. It will just mess up things even more.

@akaii78, I guess forget what I said. I don't know how you can get your data from your tablet now.

Hi,
You can try going to stock recovery and check if you have adb access with it. Then if you have, you can just pull the files using adb pull command. If you manage to connect to adb I can provide further help.

Is there an up to date guide for Rooting A2017G B04?

I am looking unlock and root my European Axon 7 running Android 7.1, and all of the guides seem to be for The US version and for Android marshmallow, do I need to revert my phone to an older version (if so how would I go around doing so?). Is there any up to date guides for rooting my version of the phone?

I used this guide 2 weeks ago to unlock my wife's german axon 7, her phone was on 7.1 stock too, but no issue, you don't have to be on marshmallow. Only advice I can give you is to read the guide 2 times or more and take your time.
Btw after you done everything use the b05 modem, my wife has no call issues with this version. I flashed the dark rom to her phone, works nearly perfect.

Step by Step, I managed to unlock it and flash the bootstack, but I hit an error when trying to flash LOS and so decided to reboot the system and try again, however when rebooting the system I got the error "Your device software can't be checked for corruption, Please lock the bootloader". And I cant seem to access TWRP anymore, just the stock recovery.
Im just wondering if I can just flash stock because I cant use my phone at all atm

Then flash twrp again, if your on stock recovery. You need twrp. Something must replaced twrp with the stock recovery.
After you flashed twrp use the files from the official Los thread
Bootloader and modem.

Unfortunately I cant seem to view the phone as an adb device, unless i select the "Apply update from adb" option in the stock recovery, however this only lets me sideload and i cant reboot it to edl mode or anything like that to install TWRP.

What happens if you are on stock recovery and type adb reboot edl. Another way to get to edl mode can be to shut down the phone and press both volume keys while connecting the USB cable, I read that somewhere here, may need some trys.
Btw,
"Your device software can't be checked for corruption" this is normal if your unlocked.

Good, you did it. Yes, after you flashed the latest official twrp,
flash the bootloader zip and modem zip which are linked at the first page of the Los thread, then your prefered rom with gapps and root if you like.

[HELP] I would like to go into developer options but I can not

Hello to all,
first of all sorry for my English, i'm using google translate, I do not know if you can help me here.
I bought this jewel from Gearbest and arrived yesterday.
I would like to unlock the bootloader and root it following this wonderful guide , but I can not get into developer options, I get the error "the settings application crashed abnormally"
I wanted to do this via the toolkit, but in EDL mode the phone is not recognized, maybe because in developer options I have to select the OEM UNLOCK.
The only good thing is that it recognizes usb debugging mode (at least I think) because I see the debug notification icon.
I can not understand where it came from, I went into bootloader mode but did not release me information.
From the onscreen screen I can only provide these info:
model number zte a2017g
version android 6.0.1
kernel version 3.18.20
build number zte a2017gv1.0.0b11
baseband version th.2.0.c1.9-00050-m8996faaaanazm
The MiFlavor version is 4.0
The smartphone does not receive OTA updates. I downloaded the global version (b05) of Nougat, the update with Android started I did not find it (I renamed the rom file in update.zip and put in the root of the SD CARD). I tried through recovery mode but it does not do anything to me, it's as if the smartphone was locked in everything and for everything.
I'm doing well ? How do I update when I download the rom? Can you please help me? Is there any system to interact with this smartphone and unlock it? I do not want to keep a phone that I can not update and root it.
Thanks in advance to who will help.

UPDATE:
I tried to manually install the downloaded ROM, but in recovery mode it does not flash the new rom ... the phone does not even try it !!!
It's as if the phone was locked in everything and I only have to keep the installed rom.
Some idea ?

Hey I would recommend clearing the data for settings if you can. To do this go to your launcher, find the settings icon and either drag or hold down or do whatever it takes to get to the app info. I haven't used stock in a long time so idk. But then go into storage and clear data. Then go and try again.
I do have one question though. How did you get usb adb debugging enabled if you didn't get into developer options at all?
For the second half of your question you won't be able to flash anything without first unlocking the bootloader and flashing TWRP onto the device. For the devices recovery idk which one you meant, but it needs to be TWRP. Good luck!

You can't flash an official zip through TWRP, it will just fail. No brick.
Edit: didn't read OP lol. If you want to update, you have to flash the stock recovery (there are stock recovery flashable zips on the Download Center) then install the update, then get TWRP again. Or you can install a custom ROM (I recommend one based on stock MiFavor 5.0, I think that the best one is ADM Team V3 (the one that's not based on B13), this way you can simply download, flash in TWRP, and you'll be done

Very poor support? It's going to get Android O, and it's got at least 1 update per month (officially). It's unclear whether that ROM you installed will be updated since it's based on an older version, but the latest (B13) breaks a bunch of stuff like Google Play Games, Maps, the GPS works awfully...

No no ... do not get me wrong.
My reference is to rom, MiFlavor is really bad. I come from 3 Xiaomi smartphones and I can assure you is another world.
The smartphone is really nice and well balanced (apart from the just enough battery) and I would replenish it a thousand times. :fingers-crossed::good:

LG V20 bricked/bootlooping/bootloader re-locked. How to fix?

Hi all -
I have two US996 phones.
Luckily, my primary phone is fine (rooted stock Oreo ROM)
The "backup" phone was previously bootloader-unlocked and also had TWRP and a stock-rooted Oreo ROM on it - but not yet set up; it booted to the welcome/setup routine.
Well, I did a "full" Nandroid backup of my primary phone (TWRP 3.3.1.0) using the beta feature supposedly allowing backup of data as well as the internal storage and wanted to see if it really did fully restore the phone without need for re-entering all of the passwords and other info for all of the apps. So, I tried to restore it to my backup phone.
Well...I screwed up and apparently didn't do an adequate wipe before flashing. Now, the backup phone is bootlooping with a message saying something like "your phone failed a security test and will not boot". I am not able to get into recovery at all.
I am able to get into fastboot mode, and on "fastboot getvar all", I see that the bootloader has been re-locked!! So, of course, trying to unlock it via fastboot doesn't work, since I am not able to get into developer mode to re-enable OEM unlock...any way to re-unlock it and get into TWRP?
Looked at Medusa Flasher, which is supposedly free (1.1.0.1) but when I try to use it I get "card not found" and it won't open, and the file needed to fix this isn't available. It also appears that it's only good for Sony and HTC phones anyway, and some serious hardware dissection is necessary.
Any help would be appreciated!
Thanks in advance.

Hi all -
I have two US996 phones.
Luckily, my primary phone is fine (rooted stock Oreo ROM)
The "backup" phone was previously bootloader-unlocked and also had TWRP and a stock-rooted Oreo ROM on it - but not yet set up; it booted to the welcome/setup routine.
Well, I did a "full" Nandroid backup of my primary phone (TWRP 3.3.1.0) using the beta feature supposedly allowing backup of data as well as the internal storage and wanted to see if it really did fully restore the phone without need for re-entering all of the passwords and other info for all of the apps. So, I tried to restore it to my backup phone.

Thanks, @Landloord.
I can get into download mode. Can I use it to re-flash my stock rooted Oreo ROM (NOT the backup, but the original .zip) or do I have to flash a KDZ and start over?
Thanks!

Flashing a kdz would be your best option right now. It's safer to start from a rock-solid base

Flashed the Stock Oreo KDZ. Thanks! phone boots now....but I can't unlock the bootloader in the usual way (using the unlock.bin file from LG) because somehow the IMEI number got nulled - all zeroes.
Edit:
Got the IMEI fixed with this method: https://forum.xda-developers.com/v20/help/us996-imei-null-0s-how-fix-t3876980 - and now the bootloader magically became unlocked.
Now to flash TWRP and a rooted image and all should be well.
Thanks again, Landloord!

Sorry, have been away from the forum for a while. Still need it?

Sure

Hmmmm....couldn't find the file anywhere on my phone or the computer. I unlocked the bootloader on that phone when I first got it four years ago.
