GUIDE
now unlock bootloader.
and go for step 4(which flash twrp recovery)
now flash the recovery which is provided by me using code.
and now go can go into recovery
****************************************************************************************************
i suggest you this guide this method do for me

Disable update CM recovery option in developer options... Then flash custom recovery.... it will work.

once flashing twrp recovery, you will need to use
Code:
fastboot -i 0x1ebf reboot
command.

remove battery after install recovery before restarting phone
then insert battery and start in custom recovery

install Custom Recovery
1) enable developer options
2)enable advance reboot and usb debugging
3)disable Update CM recovery option
4)reboot to bootloader and flash recovery
" fastboot -i 0x1ebf flash recovery recovery_twrpyulolli.img "
5) directly disconnect phone (phone displaying FASTBOOT MODE)
6) remove battery and start phone in recovery mode using volume UP+DOWN and power key
7) And YOUR are IN TWRP RECOVERY ......
THIS method work for me perfectly .....i m also having same problem of flashing custom recovery and again showing CM RECOVERY
:laugh::laugh:
Thank You...!

Which is best for yureka cwm or twrp recovery

maybe you should put that SMT AoL on a break... the YT2 one is almost forgotten.

@workdowg now that we have a permanent recovery does this mean we can start building cm and kernels? I am almost setup with my machine (just configuring Ubuntu). From what I have read on lenovo website is they messed something up with the charging and battery life in the last update

Since the bootloader is unlocked you may do what you wish. Permanent TWRP will make the job easier. Have at it!
As far as the current ROM from Lenovo.... It is really stable for me. I froze the usual suspects and I get about 3-4 days with 8-9hrs SOT. I don't game on this tablet and keep the brightness down to about 1/3.

it works in the 'live' mode? from dnx (PwrOn with both Vol pressed, screen shows 'fastboot starting...' message):
fastboot flash osloader bootx64.efi
fastboot boot twrp-1050f-b.img
you should also try to boot in the recovery right AFTER you flash it and if it goes twrp means that recovery from boot is still active on your build (and will write the recovery partition with a fresh image that he builds from the boot partition on each normal android start)
what is the OTA you're on?

while i don't know 100% whether it is working or not on your model and since those who download the files don't give their feedback...
try rebooting in recovery, when in normal android, send a adb reboot recovery or boot in fastboot mode and chose the RECOVERY as target with Volkeys and activate with Power button
check also that you flashed the correct img file (you did unzipped the file before flashing no? ) fastboot flash recovery twrp....img

I tried all the ways including 'adb reboot recovery and also tried to enter recovery through droidboot but each time it simply rebooted without going into recovery.... I also tried the temp recovery, by these commands "fastboot flash osloader bootx64.efi" & "fastboot boot twrp-830f-b.img" in this case also it simply rebooted in to android os.
P. S. I am able to enter twrp recovery through social design recovery.

any 830 owner can confirm if it is working or not on his device?

1. when you are entering the above two commands are you in DNX mode? ('fastboot starting' on screen)
2. when you upgraded to Lollipop did you used the OTA update process or you just flashed a stock Lollipop rom?
3. boot to your normal Android OS and open Contacts and in the search contacts box enter ####0000# it will open a VersionInfo window, tell me what it says under BIOS version line
by these commands "fastboot flash osloader bootx64.efi" & "fastboot boot twrp-830f-b.img" in this case also it simply rebooted in to android os.

4. right after you entered the commands it rebooted (ie you heard the tab buzzing as if you power on from off state) or just continued and booted t Android?

Help ! Boot Loop with no recovery installed

Dear Xda members, I need help with my OnePlus 2... Just got it few days ago. Great phone ! and as an android user, generally the first thing I'd do with my phone was to root it...
basically here's what I've done...
1. unlocked bootloader
2. flash TWRP
3. clean flash OOS 3.0 Beta from TWRP
4. flash CM 13 by Grarak from TWRP
5. flash Gapps Arm64-6.0-micro from TWRP
6. flash SU from TWRP
things were going fine, everything works normally, until I go into bootloader mode.
Suddenly my device goes into a boot loop...
I realised maybe there were something wrong with my recovery (TWRP).
so I tried to flash it again, but it says that my device were locked, therfore I can't flash img file from my PC...
I tried to type unlock Oem, but when I check oem device info, it says device tampered : true, unlock device : false.
I searched for a while and find a temporary solution, by typing "fastboot continue" from command prompt in PC,
I was able to skip the boot loop straight to the boot-animation and was able to enter Cyanogen.
but if I turn off and on my phone, again it enters boot loop...
so basically here's my phone condition...
1. stuck at boot loop
2. no recovery
3. locked bootloader
4. Cyanogen & Su working fine
Please anyone, help... and Thx...

I've used this guide to good success twice now, good luck let's hope you're up and running in no time.

Z17S (NX595J) Unlock Bootloader & TWRP

Hi, I'm new to this phone. Just got it 1 week ago. I tried to find any related information on the bootloader unlock and custom recovery, but it is very limited. I think maybe this phone is not well known. I would appreciate if someone can provide me the way to unlock bootloader, flash TWRP and roots. I can't live without magisk and viper4android. Thanks.

Here ya go,
1. Download and install minimal fastboot adb
2.Download TWRP rename it Recovery and move it to minimal fastboot adb folder
3. Unlock bootloader, in fastboot enter the following code : fastboot oem nubia_unlock NUBIA_NX595J
4. then also in fastboot: fastboot flash recovery recovery.img
5. you may need to format data in TWRP to get it to boot up !
Enjoy your new life !

thanks

Hi, I've tried numerous timed and it always won't pick up the command of unlocking bootloader. It always stay in the fastboot menu. I've toggled the 'OEM Unlock' function in the developer setting, as well as the USB debugging. Any idea why the device won't pick up that command?

Is it changing to unlock after you enter the command?
If so flash twrp then boot into recovery ...

Nope. It doesn't respond to the command in the fastboot. It just shows the fastboot menu. My adb is written 'waiting for device.... '.

Drivers , uninstall all other drivers and try please

I'm having the problem. Unlock is not sticking to unlock. The unlock works and the flash works but as soon as you try and reboot into recovery it hangs at a blank screen no twrp. Console says waiting for device and stuck. next time I go into bootloader it says locked. The count is 3 for unlock count is there a limit? 7-6-18 Nubia Z17 NX591J WIn 10.

I don't understand? Appears not locked? It is locked. Now I remember when I flashed my Star N997 the developer said that there is a unlock bit that has to be turned on in the process of unlocking. I think this may be the case here since it unlocks until a reboot. I am deep concerned that after a unlock count of 3 the phone will not boot anymore. Do you know anything about these things? Another thought is does the USB C need different drivers and should it be plugged into a USB 3.0 outlet?

TWRP will flash only when it's unlocked so even if it's saying it's locked go by what you can do with TWRP

I did it several times and never had a problem

i was looking for camera.apk file from Nubia Z17S phone from Stock ROM, can anyone upload it here..it should be located in system / app or app-pvt folder, you can copy using Root Explorer tool.
pls. let me know...

I'm having problems unlocking the bootloader. Has anyone got the proper TWRP for this phone? I can't find it. The one I have says FAILED (remote: Requested download size is more than max allowed). Thanks

hello links no longer works. Someone could give me back the TWRP and minimalb fastboot adb

For anyone's information, TWRP will not boot in recovery while the phone is being charged. Unplug first. You will just get a black screen.

i am also experiencing the same issue.. where can i find the drivers for this phone nx595j? or how do i uninstall the drivers for it?

Moto g4 plus recovery boot loop...

Hi guys. Few days ago I unlocked the bootloader of my Moto G4 plus, install twrp recovery and root the phone. Then I made the mistake of trying to install an update from OTA and since that day it is impossible to start the phone normally. It always starts in recovery mode, then I must go to restart to start in fastboot mode and next, select start to be able to use it. I reinstall the latest version of the recovery twrp and the ROM of LineageOS but nothing changes. Can someone tell me if there is any console command I can execute in the phone to start normally?
Thanks for your time...
