You are simply the best DerTech. You solved my problem with recovery loop after TWRP flash.
Thanks again!

Hi, I managed to get to step 9 on this but get this error when executing the command "Fastboot flash recovery Stockrecovery.img"
error: cannot load 'Stockrecovery img'
Any ideas? And yes 'Stockrecovery.img' is in the same folder as Fastboot Thanks
EDIT: Ok got it working.... if anyone else has this problem you need to hit the TAB key to auto complete... just type " Fastboot flash recovery Stoc[TAB]" and it will autocomplete like "Fastboot flash recovery Stockrecovery.img.img" hit enter and should work. Thanks DerTech99!

Thank you very much ! It worked perfectly !:good:

Stuck without TWRP
Hi all
So I have been spending a good few hours yesterday on trying to get TWRP installed on my Letv Le 1 Pro x800.
I can get fastboot and adb to work no problem. I can even flash TWRP onto my phone but I can never get the phone to get into twrp afterwards. No matter what key combo I try or how many times I reboot or go to adb again, nothing...
Can anyone help with this. I just did the steps in this tutorial above but again... nada.
Any help appreciated!:crying:

When you have rooted phone, you can try install twrp with flashify from google play store. I have make all steps too and without succes with twrp, same problem as you have. But then i have try it with flashify and it works for me now.

You put the twrp zip in the Fastboot folder and type "Fastboot flash recovery twrp-3.0.2-0-x1.img"

I found this yesterday late. All thanks to Cuoco: Le1Pro_US_CUOCO92_TOOLS_v2

It's amazing. Did everything I tried to do for days in minutes!!!!

Dear Friends How to know which version of LETV X800 you have kindly let me know i have recently bought from Aliexpress for $189.
It has Build Number BGXNAOP5501103071S and EUI Version is 5.5.011s(Stable). The camera of the phone sucks. It doesn't show update option in Setting Kindly let e know how to update so that the camera quality can be improved.
When i asked seller he advised me not to update the mobile.
Thanks for advice.

Hi Guys
after recovering my phone from a hard brick my PC running windows 10 no longer recognises my phone.
When I start the phone up normaly I get a chinese LEEco screen that just hangs. When I start up TWRP the PC does not recognise the phone . The bootloader mode does not get recognised either. My PC does however recognise that something is being connected to it because it keeps beeping everytime I connect or disconnect the phone. It also installed the driver correctly (at least the system said it had) when I changed USB port... Does anyone have a solution to this problem?

Thank You very much it worked perfectly thanks!!!

X800 Fastboot brick

Hi guys I tried to root my LeTV 1 Pro but it didn't worked.
My phone keeps rebooting in fastboot ( I see the penguin 10-15sec and it reboot again and again) or it stays alight with the penguin.
Computer doesn't recognize it.
Thanks.

Try and plug it to your computer then keep power and wol down pressed for like 15 sec: now fastboot should stick and device shouldn't reboot, so you can flash a recovery (TWRP?) and start over with a new ROM.

Thank you for your reply,
It still doesn't work, penguin stays on screen but it's not recognized by computer ( before the brick it was)
I'm not very experienced in rooting btw.
Edit : The recovery.bat in the file X1_X800_TWRP_Recovery2.8.7.0 says "Complete! The device is ready to reboot into Recovery." which I do but it keeps reboot with the pinguin on.

I recieved my phone today and it just wont stay in fastboot mode. I can do anything I want but it just keeps rebooting before I can flash anything. Any suggestions on how I should keep the Phone in Fastboot mode?

You need to install drivers. After that it will not reboot anymore. That worked for me atleast.

What kind of drivers do I need? Please link them to me I have tried a lot of drivers. The thing is that the phone also does not stay in Fastboot mode when not plugged into the PC.

It's my topic for my problem so don't ask questions for you on it please u_u

Zamul don't be mean. He just asked for help as you did...
I have downloaded drivers (I think) from https://twrp.me/devices/letvle1pro.html where I also get twrp 3.0.2.0
Btw if you are using Windows you can open Device Manager and there you will see your device and what drivers it has installed (you can always use update drivers function, maybe that will help too).
Here is a little guide how I managed to get twrp:
Just download it (drivers and intall them) (and download twrp also). Place twrp file to the folder where you have your adb installed.
In phone settings go to developer menu (first you need to unlock it) and you need to switch on usb debugging.
Connect phone to the pc via usb.
Open command prompt in your adb folder and type Adb devices (if you have drivers installed corectly you will se your devices connected under some code).
Then just write Adb reboot booloader and phone will restart to the recovery.
Type into the comand prompt: fastboot flash recovery name***.img (where the name is the file name of twrp you have downloaded- just a tip: rename it so it is easier to remember for example to twrp. Then the command will look like: fastboot flash recovery twrp.img)
If succesful, write fastboot reboot and that is all.
Btw for me it did not work first time. I had to load twrp for second time and when I wrote fastboot reboot then I immediately pressed volume up so It went directly to twrp recovery.
Hope it helps. Cheers

How to downgrade to OS 1.5 on Remix Ultra tablet?

My Remix Ultratablet current running 2.0.305 keep random restart everyday.
So I wish to downgrade to OS 1.5
I ask for help form office Jide support , they told me I need to
Q1) Problem # stuck on step #1 already , When I ask where is the Remix Ultratablet driver when I install adb and fastboot ? Offical jide support told me I don't need a driver? How so ?
I can't get the tablet connect ??
Note: 1, I connect the tablet with USB to PC
Note: 2, I turn the USB debugging option on Tablet already.
Note: 3, I Test it on pc adb folder by trying "fastboot devices" only get "Waiting for Device" error
Q2) I also try other method (Power key + Volume up) on tablet which show
"Continue
Fastboot Protocol
Recovery Kernel
Reboot
Poweroff
Forced Recovery"
But when i press"Fastboot Protocol" , doesn't do anything ?
For your references:
Steps of instruction I receive from Jide offical support so far....
1) have ADB and Fastboot running, I download the Minimal ADB and Fastboot[/URL])
2)Download Remix OS 1.5 ROM[/URL]
3) Unzip the downloaded zip file ( SK1WG.zip ) and go to the folder
4. Connect the Remix to the computer via USB.
Make sure the fastboot binary is in your PATH ) or that you place the recovery image in the same directory as fastboot.
6. Open a terminal on your PC and reboot the device into fastboot mode by typing adb reboot bootloader or by using the hardware key combination for your device while it is powered off.
7. Once the device is in fastboot mode, verify your PC sees the device by typing fastboot devices
-If you don't see your device serial number, and instead see "", fastboot is not configured properly on your machine. See fastboot documentation for more info.
-If you see "no permissions fastboot", make sure your UDEV rules are setup correctly.
8. Clean the existing data by entering the following command: fastboot -w
9. Flash images onto your device by entering the following three commands:
-fastboot flash system system.img
-fastboot flash recovery recovery.img
-fastboot flash boot boot.img
10. Once the flash completes successfully, run the following command to reboot the device into recovery to verify the installation.
-fastboot reboot

did u download the correct fastboot? you need Android 5.0 to get Remix 1.5

That makes no sense what so ever.
Maybe it would be better to ask what platform he is using to flash his device with, as the instructions he has copy and pasted refer to Linux (udev rules)

it makes sense to me cause you have download the correct Android SDK to work on certain Android platforms.
https://developer.android.com/studio/releases/platforms.html
To compile your application against a particular version of Android, you must use the SDK Manager to download and install the SDK Platform for that release.

when you turn it on,it seems you do not have the minimum knowledge required to flash a device... you should stay away from downgrading it or study adb and fastboot videos and tutorials on google and youtube before doing anything.if you do anything wrong and brick your device,the warranty will not work,any bad flash could void your device warranty.

And now what i do with my Axon 7?

Hello everyone. Meanwhile you excuse me for imperfect English but I use translator, my English language is rusted...
I have a A2017G, I have managed to unlock the bootloader, install TWRP and SuperSu on 6.0.1 version But then I have had the nice idea to update to 7.1.1 then have put update. zip file (renamed), in SD card, turn off the terminal, enter into TWRP but it Disappear!!! Only Originale...io recovery make flash and device updated to B09.
I want to install TWRP and SuperSu and put alternative ROMs but I can't do anything! If I open PowerShell window in adb folder and command "ADB reboot bootloader", the device reboot and appear a screen where to " your devices software can't be checked for corruption, please lock the bootloader", ecc ecc, If I squeeze volume on, it will get into recovery, if I don't do anything it reboot normally.
I can not get into fastboot mode, I fail to install TWRP. What is the best way to go back? or reset everything and start again? I have tried to downgrade from Nougat to MM via SD but after about 1 minute of analysis I aborted the installation....
However the phone will work normally even without all these things but I have purchased ZTE for modding and I don't bear to have half fatto...in work the most difficult thing to be unlocking the bootloader and I do this thing...

Your phone works normally
You don't have fastboot
You have stock recovery
If this is the case then most surely you have EDL working...
Install TWRP from EDL mode:
This is taken from Controllerboy's guide
BE SURE THAT WINDOWS SHOWS FILE NAME EXTENSIONS!
A) Flashing TWRP Recovery to your device.
Q: Why do I need TWRP?
A: TWRP is a custom recovery system. It lets your backup your system in case anything goes wrong. It also lets you flash custom ROMs and zip files containing patches like viper4android or A.R.I.S.E. (audio) and root your device via SuperSU.
0) Boot up a windows computer with a 64bits processor. Verify your Axon 7 is charged at least 75%. Temporarily disable your antivirus software to allow axon7tool to work.
1) Backup all the data of your phone's internal memory that you don't want to lose. Copy it to your PC
2) Download the axon7tool from here: http://www.filedropper.com/axon7tool-15-win64
3) Download minimal adb and fastboot from here: https://www.androidfilehost.com/?fid=457095661767103465
4) Unzip the minimal adb and fastboot file, place the folder with the files in it somewhere you can easily find it
5) Place the axon7tool exe in the same folder as adb.exe and rename it to "axon7tool.exe" (it's easier to work with that way)
6) Download the TWRP .img and .bin files from here: https://drive.google.com/open?id=0B4...nlaZU1NRldoRjA
7) Place the TWRP .img file in the same folder as "adb.exe" and "axon7tool.exe", rename it to "recovery.img"
8) Make a copy of the "recovery.img" file and name it "recovery.bin". Leave it in the same folder
9) Go to settings in your phone and go to "About Phone". Tap "Build Number" 7 times to make the Developer Options available
10) Go to "Developers options" and tick "Allow OEM unlock" and "Android Debugging"
11) Connect your Axon 7 to your PC
12) Open a command window by holding shift and right-clicking in a blank space in the folder where the "adb.exe", " axon7tool.exe", "recovery.img" and "recovery.bin" files are located. Click "Open command window here"
13) Type "adb devices" and hit enter. You should see one device with some code listed
14) Type "adb reboot edl" and hit enter. Your device will reboot to EDL mode. It appears to be off, but it is in fact in EDL mode.
15) Go to Device Manager on your pc and verify your Axon 7 is listed as "QUSB_BULK"
16) In command, type "axon7tool -r gpt boot recovery" and hit enter
17) After it is executed, your phone will reboot. Wait until it has fully booted.
18) In command, type "adb reboot edl"
19) Verify you now have 3 backup files in your ADB folder for gpt, recovery and boot. These are backup files in case something goes wrong
20) In command, type "axon7tool -w recovery"
21) Wait until it finishes
22) Your phone should reboot
23) Shut down your phone and boot it to TWRP by holding both the power and volume up button to verify you have TWRP
24) TWRP might ask you for a password. If it does, simply tap cancel. It will ask you if you want to modify system. Swipe to agree
NOTE: if you have problems connecting to your phone as QUSB_BULK, download Zadig and replace your drivers with WinUSB ones. If axon7tool doesn't recignise your device even when connected as QUSB_BULK, try killing adb.exe via task manager before retrying.

Hello and thanks for the guide.
I have tried this system... be gone everything OK up to number 16... when I type "Axon7tool -r gpt boot recovery ", the command window should be written "Failed to connect "... and yet the device is in EDL mode.
Be all right, on Device Manager be seen as "QUSB_BULK ", the cable being original, all steps 1 to 16 be ok...io no longer know what to do.

Easy. Hold all 3 keys (power, vol up and down) until Device Manager refreshes (you'll see it as the list of devices contracting), and close CMD. Open it again and do step 16 again

Hello and thanks for the advice. Unfortunately it does not change anything.. I have done exactly as you say but the result does not change anything...io have connected the device, Open command window, type "adb devices ", is viewed as "Cd07b2e9 device ", I type "adb reboot EDL ", it restarts in EDL, then go to management Devices and is viewed as "QUSB_BULK ", Run command "Axon7tool-r GPT boot recovery " but it says "Failed to connect ", then I'll return to Device Manager, hold volume up & Down & Power, Icon disappears and returns after a few seconds, close window and launch command "Axon7tool-r GPT boot recovery " but still give "failed to connect "...
So, recapping: I have bootloader unlocked, I can get into EDL but PC does not see device although on Device Manager it exists...
I now launch device into the wall... problem solved.

if you really slammed it against the wall, i would love to buy the back housing and speaker grills. hopefully, you were just illustrating frustration (it is a frustrating scenario), and will reach a resolution, but if you actually did smash it, i could use some parts.

Of course I'm kidding... have just purchased this device, have a great hardware but the software does not go well for nothing. I have had a dozen phones, I changed about 60 ROMs, so for me it is not difficult to change the software...ma in this case have problems. Is it possible that I fail to solve this problem? Be a way to reset everything and start from scratch? Okay, the bootloader be unlocked but not be any other way to go back? I have seen many guides but not able to solve the problem. I fail to make flash of TWRP, fail to do downgrade to MM....io hope someone help me... thanks.

are you using a USB 2.0 or 3.0 port? it may not apply to this scenario, but with Motorola and RSD Lite, I always had to use usb 2.0 ports or it wouldnt see my device when flashing.
also, the steps @choose an username listed out are the best way to start from scratch, but obviously you have to be able to have your computer see the phone in the desired mode.
@DrakenFX has several guides in the axon 7 forums that should help once the computer sees the phone as well.

I use USB 3.0 with original cable ... but if you now tell me that maybe this is my problem, then I use USB 2.0. Thank you...

Good morning...
Nothing to do... I put the original cable on USB Port 2.0, have redone procedure from window PowerShell, on command "adb devices " Everything OK, on command "adb reboot EDL " It enters EDL mode, but then all the procedures are failed... if command "Axon7tool-R recovery GPT boot "I always get out of the inscription " Failed to connect ", it remains in EDL and I just have to reboot... I replaced the drivers with Zadig 2.3 but did not change anything... are there any other moors to make flash of TWRP? exist lthough an app that do this? I remember that for LG G3 I'll fix everything with an app...

need help

Hello guys, i m facing very serious issue with my device. My volume up button not working at all and when i take my phone to service centre they said they dont have cheap( i didnt know what they said) and they refuse to repair to my phone. Now problem is i m also custom rom lover and try many roms time to time but if i accidenlty mess with my phone and it get brick than how i can go into recovery mode at that situation ?? Please help me if any one know how to go into recovery mode pc using commands. Thank u

I do not understand clearly. Do you have now a working custom ROM? Or now you are on brick/bootloop?
If you have working system:
If ADB -like minimal ADB and fastboot- (and all windowsdriver) is installed on your PC. And USB debugging enabled. And you have a working TWRP.img on your computer for example to minimal ad and fastboot folder. Then.
Connect your phone to PC with USB
Open a command prompt or run "minimal ADB and fastboot" prompt on your PC.
Type on PC prompt: adb devices (+enter)
If every driver installed correctly, then your PC will display the ID ot your Phone.
If displays then type: adb reboot bootloader (+enter)
The your phone will reboot in fastboot mode.
If you have fastboot mode:
Type on PC prompt: fastboot devices (+enter)
If every driver installed correctly, then your PC will display the ID ot your Phone.
If displays then type: fastboot boot TWRP.img (if your img file is not TWRP.img then rename it before) (+enter)
If everything is all right, your phone will reboot to recovery.

My developer friend said: you need to go a private service, and ask him to full button replace. He think, it will be solve your problem.

Thanks for reply ....by the way i have already installed twrp recovery...and the method u said using command is work when my phone in bootloader mode ? Because i cant go into recovery mode at that situation because my volume up button not work

Yes.
Install to your PC minimal adb and fastboot.
https://www.mediafire.com/file/rz87kfzmljiwne4/minimal_adb_fastboot_v1.4.2.exe/file
As I said, if you have fastboot (bootloader) [little green droid with fastboot word] mode:
Type on PC prompt: fastboot devices (+enter)
If every driver installed correctly, then your PC will display the ID ot your Phone.
If displays then type: fastboot boot TWRP.img (if your img file is not TWRP.img then rename it before) (+enter)
If everything is all right, your phone will reboot to recovery.
