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

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
I have this problem
Hello
I have your problem have you solve this?
Thanks
Hi guys. I have a problem! My letv x800 CN boots to TWRP but doesn't start the system (EUI logo loading all the time) I don't know how to transfer ROM into the phone in order to flash it. I installed all the drivers and PC recognize it. PLEASE HELP!!!
Hello all,
Just a heads up that I have little to no knowledge of modding/rooting phones whatsoever.
My phone decided to reboot by itself earlier today and was stuck in a boot loop for around 30 minutes before I managed to get into recovery mode. At this point it is still boot looping. Afterwards it just stop the boot loop and now stuck on recovery mode. Powering it off from recovery mode or by holding power button for 10s will only results in the phone rebooting itself into recovery mode again. I can get into Fastboot mode, however. Wiping cache and rebooting does not seem to do the trick as it would only go back to recovery screen after the OnePlus logo again.
Please advise on this matter
install drivers. connect to fastboot. Type "fastboot continue", this should turn on your phone but it's a temporary fix. Once it's on copy your data & perform a factory reset. - found it on oneplus forums (haven't tested by me)

Thanks for your reply, where exactly do i type "fastboot continue" ?
> First you need to install ADB & Fastboot to your Computer (Use This guide)
> Then Install Oneplus 2 Drivers (Use This Guide)
> Connect phone via Fastboot mode (Turn off the phone. Hold Volume Up + Power to enter fastboot mode. Connect phone to pc)
On the first guide (ADB & Fastboot) you'll find how to open a Command Window to issue fastboot commands. That's where you need to type "fastboot continue"

i have literally the same problem and i can't get out of this!
sony didn't make the update for xperia c4 to start automatically, so i flashed marshmallow 6.0 in this device.
And now, i can't get in recovery mode, i used a tons of guides, i try to do it with codes on sdk, on sony's flashtool(emma), on adb, it's totally useless i think there isn't a way to get the recovery mode on xperia c4 with marshmallow 6.0.
Sony, wtf?
no one?
Any helps?.. it is really impossible to root this phone?

Search for stock recovery or TWRP recovery .img file on web. ( Remember, Google is your friend! ) Rename it to recovery.img and put it into the adb folder. Then, open a command prompt there ( as admin ) then type: cd <directory to adb folder> e.g. cd C:\adb then boot into fastboot mode or bootloader and then type: fastboot flash recovery recovery.img . Now it should flash a new recovery to your recovery partition.
P.s. You need to unlock your bootloader! But you need to backup your files cuz this is going to delete them!!! Go to setings> slide down> click on about your phone> click 7 times on build till you see a message like: "You are a developer!"> then click back button> go to "Developer settings"> and find an option called: "Oem Unlock." toggle it> Then go to fastboot mode or bootloader mode and in fastboot type: "fastboot oem unlock" or "fastboot oem go-unlock" then click "Yes" when prompting. BUT you can also boot in edl mode and flash it without unlocking bootloader. To do this, try power combinations, or go on google and search for them. It may also happen that you don't have an EDL mode, so you'll have to unlock the bootloader. So: What you have to do.
1. If you have a locked bootloader, unlock it.
2. Get a recovery image ( img. ).
3. Flash it!
Well that's it! Hope you understand me! Happy flashing!

Hi There.
Maybe a newbie problèm but in order to unlock bootloader and Root my device, can't install the twrp.img file on cmd i can reboot on fastboot mode but fastboot boot twrp-......IMG still getting me no such a file...
I've checked and reinstalled drivers by autorised unsigned drivers,when i look on my Android adb device all seems good..
Any ideas?
Fastboot boot twrp.img enter see your phone load in to twrp mode .. then restart using twrp . After boot . Agin go fastboot mode and type fastboot flash recovery twrp .img (u can drag this file also if u want or manualy typing as u wish) . Enter and wait few sec. Its finish. Then type fastboot reboot (remembar before hiting entar tap volume down switch then hit entar). Now u feel viberet and see twrp logo . Then go wipe advanced wipe tik the ASDF swipe to conform. And then restart ur phone.... congarts u have succesfully install twrp ... enjoy .
THX it s more clear i ll try and let u know
First of all download the app TWRP from play store . Then download the latest version of twrp from there .
Then you have to unlock your bootloader by using the app unlock device tool . After unlocking the bootloader go to developer option and enable USB debugging . After that connect your laptop or PC to your mobile . An option will come on your screen to allow debugging to the device . Allow it permanently . Then open adb (I hope you have installed it otherwise download and install it Just google it download adb ) After installing open C drive and then go to adb . Then open command prompt there by pressing cntrl shift and right click . there will be an option to open command prompt there . After opening just type adb devices there in the command prompt it will show your device serial no. Then move the twrp file from your mobile to PC and to adb folder . Then rename it to recovery .
Then switch off your mobile and open fastboot mode by pressing power button and volume up button . then go to the command prompt you have opened before . type there fastboot devices . it will show your device serial no. Then type Fastboot flash recovery recovery. Img then wait for some time after the processing gets over in there . then switch off the mobile by removing battery and switch on to recovery mode by pressing power button and volume down button . Congrats twrp has been installed successfully in your device . You will see twrp window. If this works then thumbs up
I decided to update my old oneplus 2 to lineageos 15.1 with, but when I tried to flash the file with TWRP, it shows an error. Since the TWRP version I was using was old, I decided to update it first. Keep in mind at this point i had completely wiped my device. So, I downloaded the "twrp-3.2.1-0-kenzo.img" file, as per a youtube video where the dude managed to flash the update successfully, and gave it a go. It showed up as successful. Then i shut the whole device off, and tried to boot back in to recovery to flash the ROM again, but the thing won't boot. It's stuck on this boot screen (with the oneplus logo and 'powered by android' at the bottom), and refuses to go further. I'm stuck in a situation with the phone having no OS, no recovery and the thing won't show up when I connect it to the pc either. Well, the pc makes the 'device connected' notification sound when I plug it in, but nothing shows up on the file explorer or the device manager.
That's my dilemma, please i need help!
Thanks in advance.

You downloaded the KENZO (this is not oneplus2! ) TWRP and flashed it on another phone (oneplus2), just normal that it doesn't work and your phone is messed up.
If you can enter fastboot (vol up and power button to boot) you can rescue your phone:
-enter fastboot (vol up + power, while phone is completely off, u can also hold it until you can see "fastboot" written on the screen)
-connect device to a computer with fastboot installed
-type "fastboot oem unlock" into a terminal/cmd window if there is no error, you are good to go, otherwise your bootloader relocked, use this thread to recover
-if your bootloader is still unlocked, download the ONEPLUS2 TWRP IMG, ALWAYS make sure to only flash the roms, kernels, recoveries or zips for YOUR phone otherwise you can really DESTROY your phone!
-now type into terminal/cmd: "fastboot flash recovery *drag the oneplus2 twrp image into terminal/cmd window* and hit enter
-use vol down + power to reboot phone into recovery and wipe all partitions
-Install a ONEPLUS2 ROM of your choice
If something is not clear, use google, because this is most likely basic stuff you have to know when flashing your phone
I can in fact go to fastboot mode by holding the power+volume up keys. When I the phone to my pc it does show a fastboot device (9597b869 fastboot). What do i do from here?

i tried to follow the guide. but the bootloader, as per you description is relocked. the download link for the driver you provided shows up as empty/no longer available. that's where i'm getting stuck.
P.S, i can enter fastboot mode on the phone via power+volume up.
thanks for the help so far, i can't seem to find much help other than from you so far

so i managed to get into qualcomm mode, updated the drivers, and ran "MSM8994DownloadTool.exe" in administrator mode. it went as it's outlined in your guide. however, at the end of that process, the phone got stuck in a bootloop (the oneplus logo flashes for a moment and restarts). and can't get into qualcomm mode now, since when i connect the usb to the pc while the phone off, it lights the display (to show that it's charging, i think). any way back from this?
(i can still get into fastboot mode)

Do you still have TWRP? If yes go to TWRP and shut down the phone there, afterwards you should be able to enter qualcomm mode again.
otherwise you have to try (i think 10s power button will shut the device completely down). You should be able to enter qualcomm mode if the device is fully shut off (your scenario sounds as if the device is not fully shut off when u connect it to the pc).
Just to go sure: You are absolutely sure to have a oneplus2, are you?
