system deleted, TWRP ready - LeEco Le Pro3 Questions & Answers

Hello,
i delete the System and Data on my LeEco Le Pro3.
TWRP is installed.
Can i flash a rom with an usb flash drive in TWRP or fastboot?
greeting gizez

Boot into TWRP and use MTP to transfer ROM file from your PC to Phone. Then flash the ROM.

I have this problem, but I can't see the phone when connected to a PC. adb sideload doesn't work (adb devices doesn't find anything). Do I need to install driver for the phone? I originally used fastboot to unlock the bootloader and flashed TWRP, then installed LineageOS and gapps just fine. I then proceeded to wipe system in TWRP (I was trying to get back to new phone setup so I can transfer stuff from old phone, which I skipped the first time).
Any idea how to get around this? I tried plugging in pen drive through an micro USB OTG and a usb-c to micro usb adapter, but it's not recognized in TWRP, either. Would very much appreciate any help!

You can get your data. First try to connect phone while is in TWRP. Your phone can be detected as file manager. Try this.
If not, check my theme;

Go Advanced -> ADB Sideload, type "adb sideload aicp_zl1_n-12.1-NIGHTLY-20170516.zip" (zip of OS should be downloaded and put into "Minimal ADB and Fastboot" installation folder with name as same as the text of command). It should let you turn on system.

Also "adb push" command can be helpful. Sometimes phone is not current on adb devices list, but you can also try. As i remember, target should be /sdcard/0

Thanks, but unfortunately no luck. Both adb sideload and adb push said error - device '(null)' not found. It seems like the PC is not recognizing the phone. I checked device manager on the PC, it showed LEX727. I right-click and had it install the driver. It says driver successfully installed. Then device manager showed MTP device with a !. I again tried having driver installed, but this time it doesn't find any driver.
I'm at my wit's end... Any more suggestion?

TWRP and/or Minimal ADB isn't trouble here? Tried you both on main menu of TWRP and in ADB Sideload mode? You can also try do it trough bootloader, for this check my link and read all.

Actually, the problem is solved, by using another PC. This one showed LEX727 in windows explorer as soon as i plug in the phonr (in twrp). I was able to drag and drop the zip files to the phone and go on my merry way. Now back in business!

[Q] Nexus 4 can get to TWRP, but no image/not able to communicate with PC

OK. I have spent the last 8 hours reading and trying my darnedest to get my phone up and running.
I wiped everything, and formatted data accidentally.
Now the phone wont mount the USB so I can put a ROM on it. I cannot get drivers to make either the skipsoft toolkit or the WugFresh tool kit to work.
I have read on ADB side loading, but cannot figure out how to get the phone to get recognized in order to connect with it. As it sets right now, I am stuck at the bootloader image, or TWRP recovery. No image on the phone, and I cant seem to get the drivers to allow my PC to see the phone. (Ive used WugFresh drivers, naked drivers)
Any help you guys can give me would be awesome.
Thank you
Mark
Hey there,
Our phones are MTP devices and because of that (I think) we can't mount them as a usb drive. But yea you can use adb sideload to get yourself up and running again.
For the drivers try this: http://forum.xda-developers.com/nexus-4/orig-development/toolkit-skipsoft-android-toolkit-nexus-t1995688
On your Phone:
1. Boot into TWRP,
2. Tap advanced,
3. Tap adb sideload,
4. Swipe to start sideload.
Once it says its waiting or something like that, it's ready to sideload from the PC.
On your PC:
Put the rom you wanna flash in the same folder as adb. So if adb is in C:\adb\ then put the file there.
In CMD type in adb sideload filename.zip (filename.zip is the name of your file you want to flash)
So an example would be:
Code:
c:\adb>adb sideload CARBON-JB-NIGHTLY-20131117-1149-mako.zip
It'll take a bit to transfer the file, but once it finishes you should be able to boot into the rom and use it normally again.
Hope it works for you, regards...
You can use Wugfresh to restore to stock and start over.

download mode

I'm stuck right here as far as download mode goes.
I installed TWRP on a d800 rooted with stock 4.2.2. The TWRP install went ok but it never booted afterward.
I can get into twrp, but can't sideload anything because the computer does not connect to the device, I hear the connection noise the computer makes but nothing in the device manager.
any ideas?
May I suggest you use "adb push rom.zip /sdcard/rom.zip" instead of sideload (the sideload doesn't have to be enabled)

Thanks, I get
error: closed
I was wrong about my computer not seeing my device, it's in the device manager under Android and the adb drivers are installed.
I also renamed the rom to "update" to make it simpler
What's up now ?
Sorted it out or still issues there ?
I also tried the adb shell method.
I also tried this method through TWRP terminal and nada.
If I did something wrong here let me know, hopefully I can get it up and going

ok, let's do it like this
1. copy rom to c:\rom.zip
2. while in adb folder "adb push c:\rom.zip /sdcard/rom.zip"
that should work, you don't need sideload to be enabled.
Please test and report.

I moved the file to the root of my C drive changed the name to "rom.zip"
Copied the command you supplied and got this result
I know my phone is connected because I can reboot it by using the command " adb reboot"
I used this;
adb push C:\Android\sdk\platform-tools\rom.zip
And it is now ready to install through TWRP!
Hold your breath.......
Edit;
Failed but at least it's in the twrp list
"unable to open zip"
I think I got it, I was able to access the firmware update screen.
Sorry fir these incomplete responses, I don't want you to keep looking for a resolve while I do this.
If your still here?
I'll be back!
Success!
After nothing would work except for loading the rom through adb I decided to wipe the whole thing.
I reloaded the rom and when selected for install it opened instead of preparing for install so I thought I would reboot and when I did I was prompted by su that my device may have lost root and gave me the option to reinstall it, I chose yes and when rebooting it hung (normal) at the LG logo, however this time the charge light was flashing! I attempted to access "download" and was successful in loading the stock rom.
In the end it looks like TWRP was the culprit, it used to be my favorite but not for this device
All is well, thanks for your help...

Windows 10 laptop can't detect softbricked Nexus 4, TWRP, no OS

I've checked other threads but other similar threads were able to get the phone detected in Device Manager so...
I went to factory reset my old Nexus 4 after using it whilst my LG G4 was being repaired. Instead of wiping the data, I accidentally wiped the entire phone, OS included. I wasn't paying attention to what i was doing due to working at the same time and as a result the phone now only boots into TWRP and fastboot mode, but nothing else.
I tried to connect it to my windows 10 laptop so I could flash a new ROM but my laptop can't find the nexus 4 at all. Not when in recovery or when in fastboot.
Opening device manager shows that it is not there at all. There is no ACER usb device driver, nothing that resembles the nexus 4 at all. I've attached an image showing what device manager shows when the nexus 4 is connected and in recovery mode.
As you can see, there are no drivers I can uninstall. I have installed the google USB drivers from Android SDK manager. Still doesn't show. ADB doesn't work either.
I have tried multiple USB cables and every USB port. The phone charges when using an AC adaptor and charges when connected to the laptop. I can't try a different computer because I do not have access to one. Frankly I'm at a loss as to what to do.
When my nexus 4 was previously unable to connect I was able to see the device and just had to uninstall/reinstall/update drivers to get it working. This time, I can't seem to do anything. My LG G4 connects fine and without issue.
Anyone able to help?
The only way to really tell if it is a software or hardware issue would be to try another computer with Win7.
You may be able to flash a custom ROM with a OTG drive as well.
I had the same problem. When using adb and fastboot I get errors about like "error: device '(null)' not found".
Youtube video with id t0pV2pSw2N0 (sorry I am not yet allowed to post external urls) was helpfull and now I can see Android Composite ADB Interface again in the device manager. I still can not use commands adb and fastboot with exception of adb sideload. Unfortunately I have not yet succeeded to flash an image succesfully with sideload.
first try 2 remove any current drivers that are installed.
then u should experiment with different drivers.
the SkipSoft ToolKit have a huge selection, try each one of them (one of them should work).
begin with the ULTIMATE drivers and Adb/Fastboot Installer and if it don't work use the toolkit drivers.

For me it turned out that MTP was enabled by default. After each restart MTP was enabled again. Now I have disabled MTP and my device is found by normal adb command.
Steps:
1) Start your device in twrp recovery mode
2) In main menu go to mount and tap "Disable MTP"
3) In main menu go to advanced -> adb sideload. Wipe caches and slide to start sideload
4) On your pc go to the command shell
5) Start "adb sideload <image_name.zip>" (replace image_name.zip with a valid image). It does not matter whether this fails or succeeds. Only thing important is that adb connects to your device.
6) Start "adb shell getprop persist.sys.usb.config". As result you will see the actual setting of the USB configuration your device when starting up. In my case it responded with "mtp,adb".
7) Start "adb shell setprop persist.sys.usb.config adb" to enable only "adb" configuration
8) Repeat step 6 to check result
9) Restart your device in recovery mode
10) Start "adb devices" to check if your device is now listed.

I tried removing all USB drivers and then using the toolkit and tried installing each driver. None of them allowed my PC to detect the nexus 4. As you can see in the attachment, nothing in device manager remotely resembling my nexus 4. This is after uninstalling and reinstalling and also updateing the LG G4 drivers (it makes no difference).

Unfortunately I don't have access to any other PC for this purpose. I can't connect download software or connect USB devices to the PCs at work due to security. I tried an OTG drive but TWRP wouldn't let me mount it, apparently OTG is not enabled by default for the nexus 4.
I've tried all 3 USB ports, several different cables but no luck. I guess that's it for this nexus 4 then?
If the phone is not booted into its ROM, ADB commands won't work. You need to use "fastboot devices" with the phone in bootloader mode.
You android device will reboot in several different boot modes (fastboot, recovery, normal). For each of these boot modes a separate device drive might be installed on your Windows. So check the device drive after each change of boot mode. If needed uninstall and reinstall the correct device driver.

[Help] I bricked my Axon. Need help.

So i've gone through every thread here without success. I have a unlocked bootloader but no OS nor custom recovery and i cant get into fastboot mode to install twrp. When i use ADB it wont find my device unless i go into Stock recovery -> update through ADB and even then it only recognized my device as sideload. What can i do? When i tried to use the MiFlash tool i cant seem to get the correct qualcomm drivers installed. what can i do?
Edit: I solved my issue by downloader the stock B08 system on my S5 and then i placed it in the external sd. Then i put the SD back into the Axon and installed the system. After i had installed the system and booted into the OS i could enter adb with my device being recognized and after that i flashed twrp by using ADB.
I have a new problem though and that is that i can't install the 3.1.0.0. twrp. it only boots into black screen when i enter recovery. I can use the 3.0.4.0. version though.
You can't enter fastboot mode on your phone. Correct?
I also assume that you installed a ROM from recovery and that's what caused the brick, right?
What happens when you try to enter recovery?

Go into My Computer, manage, devices and try to uninstall all drivers that are possibly related to your device.
Unplug your phone and let the drivers reinstall by itself.
Go into ADB and see if ADB Devices works.
If possible go into ADB reboot edl and try to reflash custom recovery : "axon7tool -w recovery"
When recounting unplug your phone and see if you can reboot, shutdown and enter into TWRP.
ps : i hope you have a backup ?

Correct. It simply reboots.
Yup, i tried installing the B29 stock system on my G model and so i suppose i had the wrong bootstack becasue this is where my problems started.
I get to the stock android recovery.

It still wont recognize my device. Which driver am i supposed to have in the Device manager? Do you think i can use my old S5 to transfer a Stock system to the sd card and then update my phone manually through the stock recovery and then when i have an OS installed maybe i can connect to ADB. I read somewhere that ADB commands only works in recovery and in the OS.
I have a twrp backup of my system on my SD card so no worries there.

You should see your phone as QUSB_BULK. Installed the ZADIG drivers ? That may cure the problem.
After that, imo, it is important you can reboot edl and flash TWRP recovery again AND when it recounts, you pull usb.
Normally you will have replaced recovery , reboot ok and you can enter TWRP and fastboot also.
ps : sometimes it is also advisable to go to ADB RECOVERY directly and do the processes.
ps2 : when TWRP backup, you can always put it on SD via other phone and in TWRP restore. Normaly you're good to go then...
Try the Marshall London Bootloader Interface driver maybe?

Installing the driver and using it for the phone (device manager -> change driver manually (or something of the sort)) worked for me, but it could differ. Let me know. You don't have to uninstall other drivers just use that specific one for your phone by switching the driver manually via device manager.

Can't copy files to /sdcard/

Hello everyone,
I recently decided too install the LineageOS.
Everything went fine, but I forgot Gapps and didnt want too use my phone without them so I decided too install the ROM again but this time with the apps.
I followed the linageos guide but accidently wiped everything before I could
Code:
adb push filename.zip /sdcard/
(dunno if thats the problem)
Im using TWRP 3.1.1-1. I can get into Recovery Mode. While in fastboot modus my pc detects my phone as an OnePlus, in Recovery modus its just android.
Code:
fastboot devices
shows my serial number. OEM is unlocked.
while in recovery mode
Code:
adb push filename.zip /sdcard/
gets me
Code:
No such file or directory
Code:
adb push C:\User\...filename.zip /sdcard/
gets me
Code:
failed to copy.. remote couldnt create file
while in fastboot mode I get
Code:
no devices/emulator found
Copying by dragging the file into internal storage doesnt work neighter.
I dont know what I did different besides the wipe before the copying. Maybe the wipe deactivates USB Debugging?
Maybe someone sees where my problem is.
Thanks

I guess you don't have an OTG Drive.
you could always go 100% stock again and then flash LineageOS
http://downloads.oneplus.net/oneplus-5/oneplus_5_oxygenos_4.5.13/
well first thanks for your reply. I flashed the original recovery and tried 2 sideload now. Seems to be driver problems. So I have to try every solution with Win10 and OP5 drivers I guess?
Make sure the Android drivers on your computer are up to date and also that you don't have any old drivers from a previous phone. I accidentally wiped everything on my OP5 once but when I connected it to my Windows 10 computer the OP5 was still recognized as a storage device--but I used TWRP not the stock recovery and also used the file explorer in TWRP. With the stock recovery you should still be able to side load flash the stock ROM from your computer. If you can't it's likely a driver issue.
I had once a similar issue, although not exactly this, just something with drivers.
A long process to fix was to install Linux as a virtual machine in Windows and that worked well. I could do all I needed, the phone was quickly recognized.
Virtualbox or VMware both are free/have a free version and I used Ubuntu.
Give it a try if all else fails.
