[Q] soft-bricked nexus 7 (wifi only) 2012 - Android Q&A, Help & Troubleshooting

Okay, so my nexus got soft-bricked, on its own. I tried the following methods but none worked for me.
-hard resetting (the device got stuck to the erasing screen until its battery ran out)
-tried this guide (from androidcentral by 2defmouze) , no luck because i need an unlocked bootloader for it.
-tried unlocking the bootloader with NRT (nexus root toolkit) . the device shut down after choosing the "yes" option and didnt reboot
- tried flashing stock with NRT, again it requires an unlocked bootloader.
- tried restore stock using NRT, couldnt since no ABD device was found (the drivers are installed correctly) . the reason im pretty sure is because usb debugging is not enabled (obviously i cant enable it)
Now im thinking of enabling "force flash" in NRT but after reading the warning, that the device can get hard bricked, im having second thoughts. the warning said that that option should only be enabled if some requirements arent met (like the "required" bootloader) im not sure what "required" bootloader means. my bootloader is 4.23 and android version is 4.4.2. i downloaded the correct files, yet, im worried if this will cause my nexus 7 to be completely bricked.
should i go for it ? or should i try hard resetting it once again , with the charger plugged in ? any other ways to fix it ? please help. thank you.

[Q] Recovery

Guys, hi.
I'm beat, I admit it, the jig is up and I'm all out. I've done every possible thing to my phone and nothing helps.
I want to flash CWM7, right? I have the stock 2.1 and working root (that I know for sure). I also have Flashtool and Android SDK on my computer.
What I DON'T have, however, is a way to get into recovery and from there flash ROMs. CWM Recovery doesn't exist for my phone (Xperia X10 Mini Pro), so I got this thing (http://forum.xda-developers.com/showthread.php?t=1106146), copied the chargemon and recovery.tar into my system folder, set the permissions to all enabled, turned off my phone, turned it back on and spammed the back key -> nothing. On another try I long-pressed the back-key -> nothing. On another I installed Rom Manager and selected Boot into Recovery. The phone just restarted.
I THINK, but I'm not sure, that to use recovery, I have to have my bootloader unlocked, is that correct? For that I used this guide (http://forum.xda-developers.com/showthread.php?t=1254225) which I must say is extremely confusing - essentially, what I did was that I got msm7227_semc.cmd from here (http://forum.xda-developers.com/showpost.php?p=17384177&postcount=3) and run that -that seemed to work fine and returned no errors, on my pc.
I can't ascertain whether I ACTUALLY have bootloader unlocked, because that (from what I read in the guide) requires Gordon's Gate and S1tool - S1tool alone doesn't work for me (does nothing) and my Flashtool installation doesn't have Gordon's Gate in it.
So, I don't even know anymore. What the heck am I doing wrong, how can I boot into recovery? It used to be so easy when I had the HTC Desire
Thanks, all. It would be really appreciated if you could give me any help, because I spent hours on this and have had no success despite following all the neat guides and stuff
Angelic out
When i was in Stock Android, I had taken xRecovery to flash my first ROM (MiniCm7pro V21)
After the ROM was flashed I had CWM already preinstalled
Hopefully this (http://forum.xda-developers.com/showthread.php?t=950324) may help you

[Q] Rooting Venue 7 3740

Hi all,
I recently got a new Dell Venue 7 3740 (yeah, not my first choice, but it was free for buying a computer). Anyway, started reading up on how to root the thing. I have a couple of apps that require root.
I found this thread: http://forum.xda-developers.com/dell-venue/development/guide-how-to-root-android-4-4-4-dell-t2918427
and also the main Dell page: http://opensource.dell.com/releases/Venue_7_3740_Merrifield/developer-edition/
Following Dell's guide to rooting appears to NOT root it. Installing Root Checker confirms I don't have root. Unbricked it and got it back up from 4.4.2 to 4.4.4. By reading the first guide for the 3840, my question is ...
Is the boot image linked there compatible with my 3740?
(yeah, I know this should be in the developer section ... unfortunately I don't have enough posts ... also, I am familiar with rooting/flashing/etc, my first device that I put CM7 on was the original Galaxy S1 ... and I have CM10 on my S3.)
Tried, failed
Yeah I got this tablet with a PC too and tried rooting. It FUBAR'd on me and I had to wrestle with unbricking it. Which sorry to say is a job and a half, the images on Dell's site are corrupt for this WiFi only version (no partition.tbl file, system image incomplete). Ending up downloading the LTE versions firmware to get the missing files and rewriting the batch as the file names for the fastboot commands were wrong too. And even then the tablet wouldn't boot, so I had to store the OTA on an SD card and use recovery to flash it. Unfortunately that leaves me with 4.4.2 and the dreaded clock and browser issues. And OTA doesn't work, it keeps saying no updates are available. Spoke with a Dell rep who said OTAs were suspended and to try again in a week but I think OTA was broken for me when I tried rooting and boot loader was unlocked (which the PDF on Dell's site warns you about).
So now I have a working tablet that skips hours ahead and has general stability issues.

Hmm ... Interestingly enough, I ran through the unbrick procedure from Dell, and didn't have any issues with it whatsoever. I'm not sure if they updated the TGZ since you updated.
I have read that root is for ADB to start with. Can anyone confirm this? If so, then which package could I get for a superuser binary?

I did this process just a couple days ago so everything I pulled from opensource.dell was current. The unbrick tgz on the site shows up as 128mb for the wifi only A1195 and the A5195 shows as 821mb (odd). When I extracted the tgz it said "unexpected end" or something like that on the system image. Then again when I extracted from that extracted tgz.
Following the root process initially worked and the temp cwm recovery let me flash the supersu update. It booted with su just fine and I tried a couple apps that needed root and they worked. Once I rebooted again the tablet showed up with a USB icon and would go no further. Never having dealt with Intel SoC drivers it took me a while to get them installed properly, and then I eventually understood what "full power off" meant lol.
Do you know how I can relock the bootloader and get OTA working again, assuming I'm already on 4.4.2 from the OTA zip installed via recovery?
Thanks.

You better redo the unbrick procces cause as you are now, you won't be able to update your tablet and 4.4.2 has some issues with the clock and browser. The best way to root is by thetered cwm, I did it and it's working great.

This is quite odd. From the documentation, it appears that the A195 is for the LTE version, and the A150 is Wifi only. Since I have the 3740 Wifi only, I only pulled the A150 version.
The Unbricking process was very straightforward and everything went smoothly, and after it rebooted, it prompted that there was a system update from Dell, and that took me from the 4.4.2 from the TGZ, to 4.4.4

I see it now, I think I was misinterpreting the above statement which means I've been flashing the A195 rom this whole time. Thank you all for your help! :good:
After getting my 3740 back to "Unbricked" mode, and OTA upgraded to 4.4.4, it appears that I'm completely locked out of the rooting process.
I've tried to start over with the Dell info (unlocking bootloader), however, neither of my PC's will detect the tablet when using xFSTK (one PC - Win8.1-64bit, other XP-32bit). The tablet IS detected, however, it appears that the drivers are no longer correct(?).
I normally run Ubuntu, and thats where my Android development setup is on ... I see that xFSTK is available for Linux ... has anyone used it? or would I be better trying to fight Windows?

It is mentioned somewhere that the 3740 and the 3840 use the same firmware. Assuming that, what you can do is download the latest SuperUser zip, copy it to the internal or external storage, then use THIS, or THIS to root through CWM.

I'm curious as to what it is you're trying to do. Why do you insist on having a developer's root (just the use of ADB shell), as opposed to full root flashing SuperSu from custom recovery?

I just want full root.
Most of the info that I've read on here and elsewhere are geared to the 3830/3840. Not as much for the 3740. So, by playing with the device and learning what works/doesn't work, possibly others may find this info useful to them.
I've been having issues seeing the device from XP, Win8.1 and Ubuntu, in the 'off' state of the tablet, when the PC should be seeing the merrifield. Just this morning, after bricking it last night, I discovered that my PC seems to see the device right away if I press Vol+ while plugging in the microUSB. (again, something that may help someone else) I was planning on double checking this info later today, to make sure that it wasn't a fluke.
I do appreciate both of the links that you've posted in this thread, and I will check them out. Of course, both are labelled for the Venue 8, not the Venue 7 that I have. Since I've gained knowledge on the unbrick process I feel more comfortable trying them.
I've installed (or tried to install) SuperSU from the Play store, but it didn't appear to help much, since I didn't have the custom recovery setup at that time. I'll work on that tonight.

A quick word on getting the device recognized in off mode, what worked for me was it needs to be completely powered off and nothing showing on the tablet screen then connect and bring up the device manager. Whatever shows up needs to be "Intel SoC" so change the driver to that if needed. When flashing firmware to unlock the bootloader the device's boot screen will show an "Intel Inside" logo instead of the normal "Dell" logo. I ended up running xFSTK commands in advance (they'll wait) and then running over to hook up the tablet (powered off) via USB as for some reason it'll show up and then I hear "da-Dunk" in Windows (device disconnected) after a short while which interrupts the process (same with fastboot commands). This was the unbrick process in a nutshell for me and I'm leaving it now as is (OTA'd to 4.4.4) until hopefully the supposed update to Lollipop comes around and maybe some progress is made on rooting it.
Hope this helps you!

I have finally settled down and got the tablet rooted. What's really odd, was Win8.1 kept losing the proper driver. I'm not sure exactly why ... but suffice it to say, I got it working. It did appear to be more stable when I hit the Vol+ and plugged in the USB, but then again it may have been a coincidence.
Open source dell
If you follow the link to dell open source, they do have a detailed PDF download for unlocking the boot loader etc. The file was too large for me to upload on XDA. I just found it today while I was researching how to root this tablet. I have not had a chance to try it yet.
http://opensource.dell.com/
That doesnt work for 3740 lte. I;ve done everything that was in PDF. OTA image should be with unlocker bootloader and root but its not. ;/
Its adb root not su big difference
Does anyone have any idea to root dell venue 7 3740 lte
The open source is for venue 7 3740 wifi

Any help appreciated!

Hi everybody - any help with the following problem is appreciated, I've thrown everything I can find at it but I'm just over my head at this point!
My LG G watch worked great, up until one morning when it got stuck in a bootloop - if I had to guess, the battery must have run out at the exact wrong time, during an OTA update. Maybe. Anyway, stuck in a bootloop.
I managed to install TWRP bootloader, and apparently uninstalled everything but the TWRP bootloader, as it now has the 'no OS installed!' dialogue whenever I try to exit.
I had minimal success installing ADP drivers, but never managed to make a PC/watch connection past fastboot OEM unlock. At the moment (a few months after i had that working) my PC doesn't recognise the watch at all.
So I've bought an OTG cable, and the plan is to put a flashable ROM (hey, even the stock one if I can find it) on a USB stick, navigate to it on TWRP via install, and take it from there. Anyone know if that's what I should be trying / where I can find that particular ZIP file?
Also worth noting, I never toggled on ADP debugging when the original OS was working.
Here's the info from the fastboot screen- ANY help is appreciated!

Help needed to bypass Lock Screen

Hi, I am trying to unlock a Galaxy J1 Ace SM-J111F/DS for my colleague. The phone belonged to his younger brother who had passed away in an accident, now that he's gone, we have no information as to now to unlock his phone.
I have tried researching and searching around for methods but to no avail. I was hoping maybe someone here could provide some assistance
A factory reset is out of the question as he needed to access information stored inside the phone
Some device details:
Device is locked by a pattern lock
Unable to unlock via Google account(No one in his family knows his account name/password)
Phone is not Rooted
Phone is FRP Locked
Things I have wanted to try and done so far:
Intended to flash a bypass to unlock the lock screen
Attempted to flash a custom recovery in order to flash the bypass, however FRP is locked and it does not allow a custom recovery to be flashed
Attempted various methods of "security exploits" to unlock, but appears to be patched on current firmware
Tried to search methods of unlocking FRP, however all the methods I've seen so far requires access to developers option, or requires a flash of stock firmware.
Tried accessing device via ADB, however it does not work as USB debugging is not enabled
I'm currently out of options trying to do this by myself, we would really appreciate it if someone could help us out in this

Yes, it is "seen", but I can't do anything else to it
If it is seen, there is a chance you can get data off it.
You can install' minimal ADB and fastboot' and the USB drivers for the phone on your PC. If the phone is not encrypted you should be able to browse the phone storage in an adb shell and to copy files or directories with adb pull.

Ill jump in this one to. im in a similar situation. I have a lg g vista that no conventional method is working to bypass frp. Device is not encrypted. My prob is. I believe if i can downgrade back to stock kk which the phone was released with it didnt hve frp then so bam im in. But lgflash tool wont downgrade. Always errors. Loads of diffrent settings have been made. Also followed guides to a t.
But in ure case to if it is possible to dlmode and odin back to kk or earlier u should the be able to skil the google login totally. I dont know if ure device came with kk from factory or lolipop. Frp was implemented in loli so kk should be good. Maybe
Two comments:
1) I have a Huawei G8 in front of me. I worked all weekend with it with bootloader/fastboot. I wanted to test the lock screen/adb behavior, But to my surprise ADB does not find it w/ and w/o lockscreen. --> There are different possibilities why the phone does not show up (it worked in the past with this phone/notebook, but quit working). Before you flash make sure that your setup is working (best with an identical mobile). It seems that USB connection can behave different in Bootloader/Recover/Android OS mode.
2) I made a dirty flash (w/o erasing flash) of Lollipop over Marschmallow last weekend. The result was that many directories including SDCard0 where not accessible. Also user data was not accessible. And you have always the chance that you mess something up when flashing and you loose the content.
If the data is really important your friend could pay a data rescue company (if you don't loose your face). I'm pretty sure that programs exist that can be loaded into RAM with bootloader (fastboot boot) that provide an interface to the PC (in the easiest case, adb again).

[Guide] [A2017(G)] - Unlock, TWRP, Flash with Toolkit

About
Hi there,
I created this guide not so much as a substitute for the other guides or because this would be the best way to do it.
When I looked into rooting my new Axon 7 (international) I studied all the other guides first, but then did it very differently, mainly
because
- I am on Win 7 32-bit and some of the tools used in the other guides don't work for that
- since the other guides were created the Axon7Toolkit came along - that simplified a lot of steps.
The guide is actually very similar to this one for the 2017U:
https://forum.xda-developers.com/axon-7/how-to/complete-guide-to-unlocking-installing-t3561128
Only now with the toolkit it pretty much works for the 2017G as well without the need for tenfar's TWRP (see comments). In case I left out anything, this guide will be of help, too.
So this guide is for you if
- You want to root or flash a custom rom and don't mind unlocking the bootloader OR
- You are on Win32 and cannot use the axon7tool command line tool OR
- You want to use the Axon 7 Toolkit for the job to keep things simple
Please read all the notes below before attempting anything...
Disclaimer
- This worked well for me - no claims it does for anyone else. For the record: I was on Stock 6.0 MM B08 A2017G, no fingerprint/lock etc and went straight to RR.
- Use at your own risk, if you are unsure what you are doing stay stock - I'm not responsible for bricked devices, dead SD cards, Donald Trump, or you getting fired because the alarm app failed...
Regarding Drivers
- Qualcomm ones for MiFlash (link below)
- QUSB_BULK if going with eg the axon7tool commandline version (edl mode)
- You can use the Toolkit to install (some of) the needed drivers
- ZTE drivers - phone is set up to install them upon connect to the PC. Don't.
- Uninstall incorrect drivers, just installing the correct ones won't necessarily do the trick.
MiFlash
- right click & 'run as admin' (flashing didn't work for me without this)
- Correct driver: Qualcomm HS-USB QDLoader 9008 when in edl (check with device manager open)
Boot modes
- power phone down and boot into
- EDL by holding Volume UP/DOWN & POWER simultaneously
- recovery/TWRP (once installed) by holding Volume UP & POWER simultaneously
- fastboot: Not enabled in A2017G Stock
Windows
- 32-bit: MiFlash needed, commandline axon7tool not working
- The toolkit seems to run on Mac/Linux using a Windows emulator/virtual machine (not tested, Wine helps I guess)
TWRP
- versions: Signed tenfar TWRP 3.0.2 that is used in a lot of other guides is buggy and can do a lot of harm - not needed if you unlock
the bootloader first. You can (and should) use the latest official TWRP version.
- dm-verity: https://twrp.me/devices/zteaxon7.html
- USB OTG: Axon 7 supports this, so does TWRP - no need for SD cards. Simply use a thumbdrive with a OTG cable (with included Adapter if needed), boot into TWRP (thumbdrive needs to be connected beforehand) and click 'Mount' in TWRP, then select USB storage
Bootloader
- Afaik DO NOT lock again with custom rom installed or rooted (brick)
Root/Unlock
- Can create problems with Android Pay, playstore etc - see https://www.xda-developers.com/tag/safetynet/
- Root disabled by default in Lineage, needs flashing Magisk or SU - see other guides
- Some features root provides on Android 6.0 MM won't work in Nougat (so far anyway, eg xposed)

Thanks
bkores (for the tool), dnlilas (help in the forum), DrakenFX, Unjustified Dev, Controllerboy & all the guide/rom creators etc in this forum. (And the poor souls who came first and discovered all the ways not to do it, preventing my fall)
1) Prep
- Note down IMEI(s) from your settings/about phone/status/... just in case
- Unlock developer options (Phone settings > "About Phone" > Click "Build Number" 7 times...)
- Check "Allow OEM unlock" and "USB Debugging" there
- Connect your Axon 7 to your PC with the original USB cable - do not disconnect with MiFlash/Toolkit running.
- Open device manager to check your drivers (will show up differently depending on the boot mode)
- Run Axon7Toolkit
- Select Option 1 - Install/Test Drivers
2) Unlock
- This will RESET your device, did you save your data? (using Toolkit etc)
- Select option 6-unlock on toolkit main screen -
- MiFlash launches and one has to select the folder with the files to flash, following the instructions of the toolkit
- Check Device Manager lists your Axon 7 as Qualcomm HS-USB QDLoader 9008, if not uninstall wrong drivers and install Qualcomm ones
- The unlock files the Axon7Toolkit offers are in a folder 'A2017U_FASTBOOT_UNLOCK_EDL' - works for A2017G
(- Axon7Toolkit preview version offers different folder content to flash - have not checked that)
- One can restart MiFlash (e.g. to 'run as Admin') anytime and try again, but after the flash was succesful, do not disconnect the phone but
- Finish off with the Toolkit 'press a key to continue' (or one will have only fastboot enabled)
- A message will appear on the phone: Confirm that you want to unlock the bootloader (using volume & power buttons to navigate)
- Done. From now on you will get an annoying message on booting the phone about your device being unlocked. Just ignore and wait for a re-boot...
3) TWRP
- Unlock developer options - AGAIN etc as device was reset. And - again - enable debugging...
- In the toolkit (main screen) go to '11 Advanced Options', select <Flash boot/bootloader/modem/recovery<choose recovery partition
- In 'Open' dialog select C:\Axon7Development\Axon7Toolkit\twrp\twrp-3.1.0-ailsa_ii.img (or newer version)
- Flash as 'recovery'
- Reboot, check system boots up fine
4) Flash Custom Rom etc.
- Generally: Follow instructions provided with the custom rom you are going to flash (as they might differ)
- Boot into recovery/TWRP (Volume UP + Power after shutdown)
- No need to swipe to 'Allow system modification' - this can actually brick things...see https://forum.xda-developers.com/axon-7/help/a2017u-stuck-zte-screen-boot-factory-t3584062
- Mount/Select storage (for OTG USB)
- Backup boot, recovery, data(if needed), HLOS, System image or System (image was recommended but that did not work in my case, so I backed up system)
- Wipe/Format
- ***If you like to avoid your data partition to be encrypted, follow that thread: ( format your data partition to ext4 instead of f2fs (wipe -> advanced)????)
- Install Bootloader & then modem (or Nougat won't install if coming from MM) - A2017X_B15_Universal_Bootloader.zip & A2017G_N_Modem.zip
- Rom & Magisk/SuperSU
- GAPPS (version)
- Re-boot: Unlocked message, long first time boot - After RR, my phone show up as 2017U... well, who cares...
Any comments to correct errors in this guide or fill out any blanks are highly appreciated...
I dunno why now one has thanked this yet, it is a well written guide imo and useful for those not yet unlocked.
THANKS SOO MUCH FOR THIS!! The timing could not have been any better. I literally just bought this phone from a guy on craigslist for $270 (Couldn't pass that up coming from an LG G4) less than a hour ago. Quick question. It's a 2017u with build B25. Will the toolkit work with it. I don't see an option for this build
Hi Senny,
thanks a lot - I hope the guide is helpful, as mentioned it worked for me. Hopefully I included at least most of the pitfalls one could encounter...
Hi raphi809,
The toolkit should work fine with the 2017U (it should detect your version).
To be sure, also have a look at the toolkit thread (https://forum.xda-developers.com/axon-7/development/tool-axon7toolkit-t3573108) and the thread linked above (https://forum.xda-developers.com/axon-7/how-to/complete-guide-to-unlocking-installing-t3561128), as it is more specific for the 2017U.
The main thing I am not 100% sure with the 2017U is (as I am on a 2017G and started from Android 6.0 MM), if you have to downgrade from Nougat/certain versions before unlocking etc.
If someone could shed some light on this, that would be great!

Hi Whoooo?, first thank your for your time to write this guide.
I tested your procedure and I remain stuck at the same point than the others guides. After Axon7Tool / 6-Bootloader Unlock, MiFlash.exe doesn't launch because I am not under 64bits system. So, after a successful Xiao MiFlash package, I launch it manually (admin rights): my device (in edl mode) is not seen, whatever the driver used (Qualcomm, QUSB...).
If I understand correctly the right procedure to install LineageOS 14.1 & TWRP, Axon 7 must be unlocked in its bootloader by flashing A2017U_FASTBOOT_UNLOCK_EDL?

Hi Volumetrik,
For me the MiFlash version that came with the Toolkit originally didn't work either (as Win32, too).
Instead I used the installer that came with the beta version of the toolkit (v1.2 - there was an installer in the MiFlash folder).
The installer created two applications (MiPhone and MiFlash or similar) - one of them worked for me if run as admin.
Also make sure the right driver is actually used by windows (by checking what is used in the device manager when the phone is connected in edl mode) - Windows is sometimes funny if more than one driver is installed...
Hope that helps

Hi Whoooo?
Thank you for swift reply. In fact, I decided to work under x64 environment, so I made a fresh install. Then, I combined your guide with the others in this part in the forum.
I must say I thank you so much, for your work. For a N00b, it's difficult to sort the main steps to complete the process... even if I already did this on different devices before.
I'll explain in the LineageOS thread how I completed this conversion from a full stock A2017G B03 (MM). It's slightly similar with yours.
Once again, Thank you. :good:
It's now a few days ago since this guide has been published and I wonder why nobody seems to share any experiences. Has nobody tried to follow these steps so far? I am interested whether it is possible to start from Nougat or is MM recommended?

Hi there,
Obviously I have not tried this myself, so I only can refer to these two posts from the Toolkit thread:
https://forum.xda-developers.com/ax...on7toolkit-t3573108/post71673370#post71673370
https://forum.xda-developers.com/ax...on7toolkit-t3573108/post71861250#post71861250
...stating that 'Bootloader mode is disabled in G variant with Nougat update' and one has to either
- revert to MM or
- flash a different Unlock package with MiFlash (linked in the second post)
(There is also a note in the instructions saying that the toolkit's Bootloader unlock with MiFlashdoes not work on A2017U B25)

Hi Marcus,
I tried to find some time to reply and explain how I used this guide and two others to get my device unlocked, twrp'ed and LineageOS. It's running like a charm.
I started with a A2017G device basis with MM B03. My device was updated to the latest official update available via MyFavor network. I didn't try to update OTA.
I Used Axon7ToolKit v1.1.1 + Update_Install.bat / Qualcomm Drivers / A2017U_Bootloader_EDL. I worked under windows x64, because I experienced too many troubles to get Axon7toolkit working properly under 32bits. The only one differences I experienced and not written in the threads:
- I saw a FTM mode (Factory Test Mode) displayed in a white square centered on the device screen after unlocking bootloader. In my memory, it disappeared after TWRP flash.
- I got a problem with Flashlight, didn't work, associated with a problem to call (sms working). I flashed the modem firmware once again, it solved the problem after reboot.
- At the end, LineageOS installed, LineageOS updater strangely saw the same update version installed on the device. The only difference was the"signed" at the end of the update name I launched the update and installed it succesfully, without issue. No more update after that (until a new one of course)
Hope this will help someones

Hi, when are you planning to release your complete guide? This would really help me.
I am trying unlocking the bootloader on B11
When I try flashing bootloader unlock in MiFlash it says:
Lenght cannot be less than zero.
Parameter name: lenght
Tried restarting MiFlash, installing it again and restarting PC. Does anyone know what am I doing wrong?
EDIT: Managed to unlock using Controllerboy guide that didn't work for me at first (why I used toolkit). But I am still curious why that error in MiFlash happened...
Bootloader is unlocked. Drivers are okay, toolkit recognises the phone connected. But every time I try to flash twrp or root it says 'FAIL'.
Can someone please help?

Hi,
Sorry for the late reply -
just to clarify, are you stuck after point 2 of the guide (as root is the last step of the guide/only mentioned there)?
Personally I did root not via the toolkit but via TWRP when I flashed the custom rom (as described eg in the lineage os thread).
Problems with flashing TWRP I could think of:
- bootloader unlock not successful
- debugging/developer option not enabled
- TWRP not flashed as recovery
At what point does the toolkit report fail (maybe your problem is also worth posting in the toolkit thread)?
Alternatively TWRP could also be flashed with MiFlash (did NOT try myself - but there should be guides around somewhere).

Hi there,
I think (memory blanks setting in) that's the error I got when MiFlash was not running as admin.

Hello. Yes I have posted it there and the questions and answers section to which bkores (the one who made the axon7toolkit) replied and asked me to do a command in which I followed and replied to him with the results and he didn't reply after that. Also, bootloader is unlocked. This is what happens:
Checking ADB/fastboot connectivity...
ADB device connected!
Rebooting to bootloader...
Checking fastboot connectivity...
Fastboot device connected...
Flashing twrp...
And within a second an error message pops up with a red cross 'Flash failed!'
Sorry, I forgot to say that I couldn't follow your guide entirely because I think we are on different versions of the toolkit. I am on the latest version 1.2.0 (stable), so I don't have the option 11 to go to advance settings to install the twrp. I have just the option 6 to install directly(you can see in the thumbnail of axon7toolkit post).
Thank you so much for this guide ! Had the phone back in october and i unlocked it using tenfar tool but since it was stolen in march, i bought a new one last week and this is so much simpler and safer !

Did you try booting to recovery after the failed flash attempt ? I had the same issue with the fail message (toolkit 1.2.0) but twrp was running fine.

HURRAY! ! !
Well no it didn't work until today I tried the option to restore from bricked device to b10. Out took me to miflash and asked me to unlock bootloader? Dunno why, it's already unlocked, anyway , after that was successful I went back to the option page of the toolkit and selected 'install twrp', and this time it flashed! It didn't stop on the 'failed to flash twrp' message but still gave me a 'flash to boot into twrp' then I followed your advise to go to twrp directly from there and it had installed. I'm so happy thanks loads dude. :laugh:
Worked like a charm! Thanks for posting the guide
Edit: Went from locked Nougat to Unlocked Lineage.
Whole process took me about 2 hours, but if you are better at following the steps than me you'll probably be able to do it in 1 hour.
