[Q] Help unlocking bootloader on a stubborn device?

Hi folks,
I've browsed a number of other threads looking for an answer, and tried a number of methods but I feel like further attempts without asking for help are going to be shots in the dark. The issue I'm experiencing is really strange to me, as the device will boot all the way into the OS before rebooting itself after a few seconds. This is my friend's tablet, and I assumed it would be fairly straight forward for me, but that was an incorrect assumption. All apologies if there's a clear cut answer to this solution posted somewhere, I spent quite a lot of time between reading threads here and various search results before finally swallowing my pride and posting here.
Anyway, what the device is doing: It reboots within seconds of booting up to the lock screen (which is responsive to input sometimes, but not others). When it is responsive, I can unlock the device, but I'm not able to do much else before it reboots. As far as I can tell, ADB debugging is not turned on, but "adb devices" returns the device SN when in recovery/sideload mode.
I am able to access fastboot without issue, which displays the following:
PRODUCT NAME - grouper
VARIANT - grouper
HW VERSION - ER3
BOOTLOADER VERSION - 4.23
BASEBAND VERSION - N/A
SIGNING - not yet defined
LOCK STATE - LOCKED
Click to expand...
Click to collapse
I can issue a "fastboot oem unlock," which will bring up the unlock confirmation screen. Here, one of two things will happen.
It will either drop back to the fastboot screen with "Unlocking now......" displayed in the upper left corner of the screen and do nothing, or start the bootloop described above. On the PC side, I get "FAILED (remote: ()"
In recovery mode, it says "Android system recovery <3e> KTU84P." and I'm able to push files via adb sideload (though I had to install Koush's universal ADB driver) . I tried applying the signed-nakasi-LRX21P-from-KTU84P zip, which made it all the way to "patching system files," before rebooting, so I thought I was going to be in good shape, but the bootloop returned. I've also tried sideloading nakasi-ktu84p-factory-76acdbe9.tgz, as well as the image-nakasi-ktu84p.zip from inside the .tgz, but I get "E: footer is wrong, E: signature verification failed."
Even trying a data wipe/factory reset from recovery mode doesn't seem to do a thing, despite it claiming to wipe the cache and data partitions.
Anyway, I'm optimistic considering the tablet is booting (or at least kind of before rebooting). I've tried both the Nexus Root Toolkit (on two different win7 machines) and even went so far as trying it all manually via what they're now calling Android Studio and its dependencies. I'm wondering if either a) there's some kind of image that doesn't require the bootloader to be unlocked (as I was hoping would be the case with the above reference signed LRX21P/Lollipop update zip), or b) if I'm missing something in my attempts to get the bootloader unlocked.
Any thoughts or considerations would be greatly appreciated. I'm not sure what to try other than starting from scratch at this point.
Thanks!

How to unlock bootloader if I have no access to Android GUI?

Hi guys,
a week ago my ZUK Z1 started to bootloop without any evident reason.
I found it in this state picking it up from my pocket, so I guessed it was due to some random reboot that occasionally happened to it.
So, stating that:
- I'm with original stock CyanogenOS,
- I never rooted, or even accessed to the recovery menu prior to this event,
- I'm perfectly able now to communicate and send commands to device via adb or in fastboot mode,
problem is that I did NOT enable "USB debugging" and I did NOT OEM unlock when I had the chance to reach Developer options menu through the Android GUI (now I'm blocked by bootloop), resulting in an obvious "no unlocked device" error message each time I try to flash or write system partitions.
The output from "fastboot oem get-info" confirms this status.
I'm operating from a shell with adiministrator's grant in Windows 8.
No luck with "fastboot oem unlock", "fastboot flashing unlock_critical" or "adb root".
I used also "-i 0x2b4c" (vendor code) option in my commands.
Then, my question for you:
is there still a way to unlock bootloader in order to recover with CyanogenOS stock image, in this condition?
I saw there's a "debuggable" image on Cyanogen site, but I've no hint on how to use it and if it could help me.
Maybe ZUK has to provide to me an unlock key: I read on this forum that OnePlus and Huawei have similar option.
Thanks a lot in advance for any hint and suggestion you can give to me.

Sideload the official stock rom with zuk z1 tool. That s how i managed to un-brick my zuk. Download the stock rom , cm-12.1-YOG4PAS3OH-ham-signed.zip from this page https://cyngn.com/support. Use the toolkit provided here : http://forum.xda-developers.com/zuk-...alpha-t3235964 to sideload the rom. Wait until the phone restarts and thats it. You must also install adb and fastboot and have adb driver installed.I used the shenqi adb composite driver, but i guess the universal adb driver can work too. I had the same problem. Stuck in bootloop with USB debugging not enabled and bootloader locked.
Or you can try to fastboot the stock rom with the command provided in this useful tool.

Thanks a lot Extentho for your feedback.
I've already tried your fair suggestion: unfortunately, I'm stuck at the end of sideloading the signed .zip.
In fact, I see on screen logs that it's applying the update "unconditionally" (that sounds good), but nevertheless, when finished it returns "xfer: 1.00x" on PC shell and in recovery menu, on device.
Now, either if I reboot or power down and boot it again, the result is the same: still bootloop-ing.
Of course, at any other attempts leveraging on administrative privilege, it says that "device is locked", including those done through the shell tool.
Some excerpts from my last launched commands:

You must have the phone in sideload mode. There is an option to sideload in recovery menu.
Then use the command to sideload from the toolkit. The stock rom must pe renamed sideload and placed on desktop.
If the phone communicates in any way with pc, there is still hope. When you start the sideload process from pc, the phone should show an animation showing the flashing process. Post some pictures from where you are stuck, so i can make an idea about what is going on

my zuk z1 stuck to bootloop,
and android debugging is disabled.
phone can not detecting in fastboot mode.
please help.

I've tried also with the toolkit, but it's heavy bugged (also in 5.4 version) and, after all, it gets the exact same problem like me (not surprising, it launches my same commands ).
There's no useful image or snapshot I can share, because I see the animated green android logo moving its antennas on my device, while logs below saying that it's verifying package and then it's unconditionally overwriting system partition.
It seems all so normal and plain.
At the end of the process, no "installation complete" message, but simply I get back to recovery menu (where I started from).
In other attempts, I also wiped cache and user data, prior to rebooting, just to test if it was going to change something, but no luck.
The phone reboots, the "Cyanogen" logo starts to glow for 7/8 times and then... bzzzz, short vibration and all over again (i.e. bootloop).
I tried with an older official signed .zip from Cyanogen OS (cm-12.1-YOG4PAS3AJ-ham-signed, instead of newer cm-12.1-YOG4PAS3OH-ham-signed), but even worst, it fails at "verify package" step, aborting procedure.
MD5 signatures triple-checked each time versus source.
I saw some threads where it seems possible to change the bit, on system image, controlling developer option, to manually post-enable unlocking, but it's suitable only for Nexus or OnePlus One. No instructions for ZUK Z1.
Or maybe do I need a "donor" sharing a stock .zip with this option yet enabled?
Bootloop would be still there, but I possibly could enable to "flash", "boot" and "shell" vs the device, giving me much more options to try.
One last doubt anyway. If I press "Volume Down" + "Power" button at boot, I get into a menu like this:
http: // postimg.org/image/s5badiefh/ (remove extra spaces).
Viewing other examples posted on forums, I noted that at least the "Factory reset" is missing.
Could it be an hint for anything useful?

For me, this method worked exactly as described, booting into stock rom correctly.
now, if you mentioned it in the picture, there is another option. so, i ve noticed too this menu. There is an app called QPST wich can help you. Follow this thread: http://forum.xda-developers.com/zuk-z1/help/bricked-zuk-z1-t3277257 .
So when you enter in QFIL, connect the phone to computer and boot with volume down+ power into this menu from your picture. The Qfil app should detect some ports. You must choose the 9008 one, from what i have read.
Anyway, for me this method, didn t work because the pc couldn t detect the right port, only the zuk tookit did it for me.
You read the thread i suggested, and try that method, it may work for you.

Thanks again Extentho.
I saw QPST trick, but it's not catching right port and/or not getting right permission to stop phone from re-booting.
I think that adb/toolkit method should work also for me. I made attempts with other official ROMs: I noticed that for the older ones, the result is a bit different. They get stuck in a "black screen + notify led lighted in blue" state, rather than bootlooping.
Maybe erasing system partitions is needed, but I'm very reluctant to such dangerous way, without expertised advice.
Weirdest thing is that I did anything to get this situation, I just found my device in this mess.
Of course ZUK official support is well silent at my requests.

Try to post some pics about the troubles you encounter. If we receive a solution, this may be helpful for all of us in the future. Now, exactly, what can you acces on phone(recovery, fastboot, )?
Also, check varios threads from other phones with the same problems(one plus one, lg , htc) ,etc. Find a solved situation like yours, and we may adapt that solution to you

Hi guys,
Just to close this topic.
I was finally able to install the ZUI ROM through the QFIL program.
It's a little bit tricky, due to the fact that it is strongly suggested:
- to use a Windows 7 machine started without Signature Enforcement enabled;
- to start QFIL (admin mode) and be prepared with all needed files loaded in its GUI;
- to power off the phone, then, while pressing volume up button, inserting the USB cable, attached (better if) on a 2.0 port to PC;
- to be fast pressing "Download" button on QFIL program.
After that, I unlocked the bootloader and performed a lot of alternative recovery process.
So, I installed on the device:
- ZUI ROM
- Cyanogen OS convert from ZUI ROM
- Cyanogen OS last updated ROM
- CyanogenMod 12.1 last nightly ROM
- CyanogenMod 13.0 last nightly ROM
and the winner is...
...
...
...
... none of the above.
Each time the very same behaviour: bootloop. So, my last conclusion is: hardware failure (I guess wi-fi module).
I give up.
But for anyone searching a safe way to unlock a bootloader without accessing to developer options: the QFIL method works like a charm (once installed properly).
Thanks for support.

Good Point, I know my thread shows up first on Bing whenever I search for my phone and rooting help.

I have another XT and followed all instructions fine but no SuperSU when checking the phone. I tried flashing it twice (the one from the OP in main thread) and nothing. Am I missing a step?
I had installed fine on the first phone. this new one is 100% stock, unlocked bootloader, installed TWRP successfully but no supersu and root checker confirms no root.

Is it B140 or what? If you are missing a step, only you can check that.

If you follow this guide there should be no issue. The rootmygalaxy link should be pretty straightforward at unlocking the bootloader. The guide should be stickied in the OP.

Yes use a different browser. Not working with chrome but working with edge. Go to the same link, it will bring you to EMUI 5.0 page, towards the top click on "download" then on the following page under the search bar click on "unlock bootloader" and it will bring you to the unlocking page. Just confirmed working. Updating the guide and will make a new post for root and twrp

Unlocked the boot loader, now adb/fastboot-15 Second won't work
Hello guys!
I used the 15 Second minimal adb/fastboot package from this site to unlock the boot loader. All seemed to go well, a screen message said success or something like that. It's been over 2 weeks since I had to put the phone down and take care of some other business. Now, after turning the phone off and then back on again when I am ready when I type in "fastboot devices" in the elevated cmd window in the adb directory the only message that comes back is "waiting on the device." Or the equivalent. I have tried what I could find from searching with Google to no avail. I am pretty sure that I am using the same cord, laptop, and everything that worked when I unlocked the boot loader. So, I am at a loss.
My goal originally was to use madvane20's slim downed version of b180 just to get it working again as my almost 2 years old P10 was stolen. I have no money in my budget for a new phone until Feb. 2020. I last talked with him in a series of PM's ending around May of last year, when a reply stated he had to get back to work on the last part of it. I have since seen a post referencing that it was ready in a package that after I had successfully unlocked the boot loader, it would root and install everything. This would have made me a happy guy... but I also noticed a custom ROM is now to be had based on Android 7. In order to get my Bank App's updated version of it's Mobile App to work, I have to install Android v 7 or higher. That's the main app that needs v 7 or better that I use daily. Several times...
But, now when I power up the phone, the first message is, "Your device has been unlocked and cannot be trusted... Press the Power Key now to reboot. Or the device will automatically reboot in 5 seconds." Which it does, the first time walking me through the Set-Up process, now it just boots into Huawei's EMUI 4.1. But, I cannot get adb to find the phone to follow the remainder of the instructions in the guide, "AT&T Huawei Ascend XT H1611 Feb27, 2017 update all things Root and TWRP (guide)"
Nor, can I get into the Recovery mode using the Vol Down/Power Keys.
So, where have I gone wrong or what is my next step? Since the phone can not be found and I can not get into Recovery using the proper keys what do I need to do and how do I do it?
I want to:
Root the phone.
Install the custom ROM I mentioned.
Or, Install an upgrade, if possible, to Android v 7... But,
can not get the phone recognized to get into a Recovery mode (is that right?) to push TWRP to it as well as the other files
it needs and to do whatever the Guides tell me to do.
Specs on the phone:
Model: H1611
Build: H1611C07B180
EMUI v: 4.1
Android v: 6.0.1
Security Patch level: September 1, 2017
Baseband v: 20234
Kernal v: 3.10.49-g03b627c
Sorry for the long post, but I thought it might answer some questions that came to mind before replying back.
Thanks in advance. I'm not here often, but when I am I am always relieved to get out of some jam I have gotten myself into!

mike0921,
What happens if the phone is in normal mode and you type "adb devices" from the PC adb directory command prompt?

I just now found a new(er) USB cable for the phone. I also uninstalled the H1611 under Portable Devices in the Device Manager and rebooted the laptop. Where before, under Events the message was ".... needs further installation..." it now showed a successful install.
At the "adb devices" command, nothing happened, no response. I went and found the directions and explanations for the use of the top 30 commands. It told me to reboot the bootloader. A screen on the phone had me confirm the RSA command. Afterwhich the Fastoot&Recovery Mode screen with the little green Android guy with the message Phone Unlocked, FRP Unlock messages.
I went back to the elevated cmd window and at the adb directory command prompt entered "fastboot devices" and Voila! There were some letters and numbers, five or six spaces and the word "fastboot."
So, am I good to go with the rest of the steps in the guide from here? A question, about him saying to flash the Superuser zip file using TWRP. Is that suppose to already be on my SD card to flash it or can I flash it from my laptop without having to touch the phone or current USB cable? It seems stable but I am a bit gunshy and don't have much faith left in the old equipment I am having to use. A very old, refurbished HP Elitebook 8460P which is running really wonky, a not too new USB cable, the last of five I dug up and have used and finally works but is a bit loose, and Windows 10 1903 etc., which has disappeared all kinds of things I am having to run down) Can I use the "push" command to move the zip file to the SD card? And is that a fastboot function or an adb function? I seem to have read somewhere along the way to this point here that "push" is what I want to do, but powerserge1's Step 7 states to flash it using TWRP. I just want to check. And should questions from here on out be placed in his 184-page thread? I still haven't managed to read the whole thing, it seems to go off in so many other directions that I don't think I need to travel down. But, I will follow your advice.
I want to say a hearty thanks for your help. I was stuck, confused and frustrated at getting no results from Googling and reading for hours and getting nowhere it seemed. And I think I am good to go now.
Thoughts? Suggestions?
Just to be clear, The SuperSU zip file is currently on my laptop in the adb directory. Not on the phone.

Just to be clear, The SuperSU zip file is currently on my laptop in the adb directory. Not on the phone.
Click to expand...
Click to collapse
And after backing up in TRWP, I just checked the SD card's contents for the backup and saw the SuperSU zip file neatly placed on it as well. Just to be clear!??!
Okay, I somehow screwed this up I think. I was a little distracted by a friend dropping by. After telling her to give me a minute, I looked back at the phone after following Step 6:
Step 6: Confirm phone goes to FASTBOOT & RESCUE mode.
a) fastboot devices (to make sure your device is recognized)
b) fastboot boot TWRP.img (boots TWRP.img from Step 3)
c) The phone will boot into TWRP. Always select Keep Read Only from the first screen every time you go into TWRP.
Peek around a bit if you want to, then use TWRP to backup your stock recovery to external micro SD.
d) Reboot bootloader from inside TWRP to flash this custom recovery image (no adb command this time, you are rebooting to the bootloader from TWRP, you will see this option under "reboot" in TWRP).
e) fastboot flash recovery TWRP.img (now flashes TWRP recovery to the phone)
I then went to Step 7:
Step 7: After phone reboots, get into TWRP recovery repeating Step 6, a and b or hold the power button and volume up button from power-off state, then release when you see Huawei logo.
But now, the phone isn't being recognized again. And when I shut it off, hold Volume Up and Power buttons, I get a screen that asks if I want to: Reboot system now; Wipe data/factory reset; Wipe cache partition. Not the Recovery Screen with the options I got used to seeing in little green characters.
I tried the Reboot system now option and I'm back into the Huawei EMUI with everything appearing unchanged. Powered off, did the Vol Up + Power buttons and am back with the screen offering the three options I mentioned above. And the phone not being recognized after the "Devices" command.
Can you clarify my confusion? What am I doing wrong? Or not doing?
Thanks.

I just now found a new(er) USB cable for the phone. I also uninstalled the H1611 under Portable Devices in the Device Manager and rebooted the laptop. Where before, under Events the message was ".... needs further installation..." it now showed a successful install.
At the "adb devices" command, nothing happened, no response. I went and found the directions and explanations for the use of the top 30 commands. It told me to reboot the bootloader. A screen on the phone had me confirm the RSA command. Afterwhich the Fastoot&Recovery Mode screen with the little green Android guy with the message Phone Unlocked, FRP Unlock messages.
I went back to the elevated cmd window and at the adb directory command prompt entered "fastboot devices" and Voila! There were some letters and numbers, five or six spaces and the word "fastboot."
So, am I good to go with the rest of the steps in the guide from here? A question, about him saying to flash the Superuser zip file using TWRP.

Sorry for the delay. What's the latest status with attempts to root the phone?

I know it's the wrong forum, but....please take a look

I really need the help of one or more of this forums intelligent minds. As I'm sure you'll see, I've posted this in the QA forum, but have had no hits so far....thus the reason for posting here.
So, about 6mos ago, my Nexus 10 stopped working and I couldn't get it back working...eventually moved onto a new tablet, which now I hate....
Anyway, I figured I'd head back to my N10 because I loved it. However, one of the reasons I left it was because it was stuck in bootloop and I was pretty sure it was bricked.
The bad news, I have followed MANY, if not ALL, of the suggestions on getting it back, I just cannot get it to boot. The good news, fastboot connects with the tablet. So, some specifics:
The tablet WILL boot into fastboot and I can send commands and the tablet is unlocked (also, I believe someone said they had issues because they had an older version of ADB and Fastboot. I'm pretty sure I downloaded the 'most current' version 1.4.3). So, with that, I was able to do the fastboot erase functions, such as cache, userdata, system, etc... and then also load the bootloader (mantafm01) and also send the stock .zip file (image-mantaray-....) and the tablet appears to load everything fine. Thumbs up, right? However, when it reboots it stops at the 'erasing' android bot and will not pass that. I left the tablet in that state for a few minutes all the way up to 3 days...no success.
I also tried the above using Wugfresh only to have the same thing occur. So, basically, I am stuck at 'erasing' and I don't know what to do. I feel confident that the tablet has the ability to be brought back to life, I just cannot figure out how/why all of the attempts lead to the same issue.
What I can also tell you is that while fastboot 'sees' the tablet, the tablet does not appear as a device in "My Computer" like it normally did when connecting via USB. I am using the original USB cable and have tried on multiple computers, all to no avail. I've downloaded/installed the drivers, as instructed on many links. Also, while I can get to the 'Recovery Mode' by pressing Power, Volume Up, Volume Down, if I choose "Recovery Mode" on the tablet, it reboots and goes to the 'erasing' screen. I have tried flashing TWRP on the tablet using fastboot as well. And, sometimes, not all the time, the TWRP blue/black screen appears but it will not progress past that screen (i.e., it doesn't go into recovery).
So, if you can, please help. I believe I have followed all of the instructions, but I have to be missing something or not following something correctly. I'm stoked that it looks like it's only soft-bricked, I just can't get it un-bricked.
Thanks in advance! I'm at my wits' end

Try fastbooting a recovery like TWRP thati s updated then flash a rom.

disclaimer: I might be no help at all!
You have fastboot -- go learn all the fastboot commands... you need to know the tools and figure a solution!
erase... hmm? why? What about factory reset? I see you are not using LOS 13 but stock image... need root? Basically, I would factory reset/wipe sdcard, then install recovery (TWRP) [okay, so first you would need to use fastboot to install custom recovery)...THEN, push (fastboot an image.zip (LOS or stock) to sdcards, install, and reboot!
Good to have WUG... another tool in the chest (I have never seen it or used it)
Ok, so one clue is that if your computer cannot see it, that says to me RED FLAG... ADB drivers? but you say fastboot works, hmm... I think this is the problem... Koush's universal ADB drivers? official Google drivers? Could these help!
Erasing screen? Hmm...
I would say, for the hell of it, try flashing different ROMs, Recoveries, and Drivers.... you are basically trying to...
Factory Reset/wipe SDcard [system, cache, ... everything], Flash custom recovery (optional), then, some how (fastboot or mycomputer) get an image on to /sdcard, then, install, then, reboot!
Good luck!

Why not try this
I have not had this problem with my Nexus 10 but I did once with my Nexus 7 and it may help you.
Instead of trying to flash TWRP and run it (which is not working for you) why not boot into a temporary copy of TWRP and then work from that? To flash TWRP normally (persuming you had renamed the img file to TWRP which makes it easier) you would enter 'fastboot flash recovery twrp.img'. Instead of doing that type 'fastboot boot twrp.img'. This boots into TRWP and from there you will be able run all the options and from there flash TWRP and other images as normal.
If you are having problems with drivers have you used 'USBDeview' ? Run this as Administrator and delete all references to any phone or tablet USB driver and particularly look for devices with Vendor ID '18d1' or '04e8'. Just select them, right click on them and select 'Uninstall Selected Devices'. When they are all cleared reboot your computer and plug your tablet in and it should install the correct driver.
Another option I used successfully with a Nexus 7 in a boot loop was to connect it while running Linux. I don't have a Linux on a computer so I installed one in 'Oracle VM VirtualBox' I don't know Linux but after Googling for help I installed Peppermint Linux and then ADB for Linux. I downloaded the 'TWP' image into a folder in Linux and any other images I wanted. Connect your tablet to the USB port and then on the top menu in VirtualBox select 'Devices' then 'USB' and tick the option which shows your tablet. I then went into what we call a command prompt in Windows but which they call 'Terminal'. Then type 'ADB devices' and if you see it on the list use ADB instead of fastboot. As I mentioned my Nexus 7 was in a boot loop so I typed 'ADB wait-for-device' and as soon as it looped to a point where ADB could see it then the looping stopped and I could flash the images and recover the tablet.
All the best. I hope you are successful.

As long as you can get into bootloader mode, your good.
NOW
If you can't get into boot loader mode? as far as I know...
You're ****ed.
Unless you want to set up usb boot (might not work on Exynos, idk, this is magic to me) and solder the connectors and flash it like they do in factories. That's next level **** too, and considering an N10 is 100$ on amazon you're better off just grabbing a new one.

Newbie trying (and failing so far) at my first root

Hi all,
First message in this wonderful community.
Anywas, having owned a Galaxy Note 3 for a few years now I thought I'd give it a shot at installing a new ROM to get it in better shape and try to stay with it a bit longer. Nothing really wrong with the phone other than getting a bit sloooow, specially the camera.
Anyways, not being a very geeky person, I soon realized the learning curve is steep.
This is what I've done so far:
1) Identified the model (SM-N9005)
2) Downloaded and unzip the SDK platform tools
3) Downloaded the TWRP custom recovery
4) Unlocked developer tools, allow unknown source (not sure if that is needed) and allowed USB debugging. In this phone I think there is no option for OEM unlocking.
5) Installed latest Samsung USB driver
5) Tried to proceed with unlocking the bootloader. This is where I ran into issues:
- I installed ADB Installer saying YES to everything
- Connected phone to pc with a usb cable
- From the command prompt (in my user) I executed adb reboot bootloader. I initially got an error (something about daemon and a port?....) but was able to move ahead
- The green android logo appeared along with this message "Downloading ...Do not turn off target!!"
At this point, pressing the volume down, power and select at the same time I tried to get out but kept on coming back to the same android menu stuck in "Downloading ...Do not turn off target!!". After the third try, a new warning message came up asking me if I want to proceed or reboot phone (pressing volume down) and I rebooted the phone to "escape" this predicament. I thought I was going to brick the thing!
Anyways, any recommendations on how to proceed? Is there an easier method to root the phone? Or to circumvent the issue I encountered?
As you might have guessed by my message, I can (sometimes) follow instructions but the underlying knowledge of what I am doing is .... well ...missing? :silly:
Hope you guys can help me. Thank you all in advance for your assistance.
