letv x3-50

Hello Dipcore!

Can you help with firmware for Letv x3-50 3D 4k? My problem start after upgrading my tv by firmware from x3-55, and my screen totaly not working. I connect PC to TV via UART (UART-VGA-USB(pl2303)) and Putty and going to mboot. I try to use unknow firmware and get on terminal [MENTION=220060]UnKnOwN[/MENTION] command 'store_secure_info' - try 'help'@. Next my step will find correct firmware or unpack current file and put in new bootloader.

Better late than never.... Please have a look.
[Android Software Development] dipcore:
According to the logs you are trying to flash twrp version of SuperSU-v2.79-201612051815.zip which you probably downloaded from http://www.supersu.com/download

That wont work.

My recovery is slightly modded stock recovery so you have to use edify script version of the update:

https://xdaforums.com/android/software/zip-letv-super-tv-x3-55-x3-55pro-x3-65-t3592193

I just converted the supersu update zip from sh script to edify script, please use it.
[Android Software Development] egzthunder1:
That is extremely strange. I downloaded the one from the post and I placed that file specifically in an empty thumb drive. Maybe I transferred the wrong one (as I had a couple of other versions of SuperSU in the same directory in my phone). I will try again and will let you know.

Hopefully, it is as simple as this... But I do have to point out that I have not been able to flash a single zip file (your test files, SuperSu, or even gapps, which I downloaded through opengapps).

Edit: Well, I just tried again with the file from the post you provided. This time around, I placed the zip in /cache and I tried to flash it from that location as opposed to trying from either a thumb drive or an SD card. Long story short, it spit out Status 7 and failed to install it yet again complaining that there were simlinks missing (this may be due to Kingroot being in my TV now). I also did try again to install gapps (also from cache) to no avail.

I will try to get the logs yet again.

I have a mystery. I've got an older build of dipcore's installed back from before the recoveries were out. Ive got an 8 GB and 16GB USB 2 drive. Ive formatted them with FAT32. When I get to the update screen I get red text saying (something similar to) No update on USB. If I boot the TV with VOL+ pushed in, I get the blue update bar but it will say that the Update failed. Am I doing something wrong? I'm trying to install the 0.03 recovery and then the test rom. Do I have to go back to stock first?

Hi,

I wish to flash your recovery & Custom ROM, (like Mr.Shnamukhaa) did, is there any step by step instruction, along with the custom ROM's link?

Mine is x3-55 (Super3 x55).

Thanks in advance.

Stuck in a boot loop

I tried updating my tv's firmware today (OTA) but it failed. After the update, it gave me an error stating "Desktop" failed to start and I was not able to use the TV. I tried troubleshooting myself but of no help. The customer care in India are closed on Sunday.

The EUI version that I updated is 5.8.057S_0517

After searching on the internet, I landed here to figure out how to custom reset the firmware. I followed all the steps as mentioned but I am caught in a boot loop (the colored logo, that flashes Letv). and dont know what to do.

The recovery worked once but then I was a little greedy and went ahead to root by installing dipcore's custom ROM but since then I have had no luck. My experience is similar to what the user hotblast has mentioned in his posts.

Any information to either reset to factory stock or a fail safe approach to root and install a custom ROM will be appreciated.

Thanks.
[Android Software Development] dipcore:
The recovery is for 3-rd generation letv devices. Make sure yours is x3-65pro, not Super4 x65pro.

PS.

I do not have Super4 device. I was trying to "crowdfund" buying a cheap leeco android bar which uses the same hardware to be able to test builds and create the recovery for Super4. But nobody wanted to donate.
[Android Software Development] dipcore:
- What firmware were you using before the update?

- Make sure you are waiting enough after resetting to factory settings. The first booting can take up to 10 minutes.
[Android Software Development] vinaysharma76:
Finally with some help from whatsapp group and trial errors I can successfully flashed custom rom and recovery on my super x3 65pro 3d version. One interesting fact i noticed is when i switched to this rom over chinise version audio search function in play store and YouTube was working very smoothly. But i faced some issues in hdmi inputs. So i reverted back to stock Indian rom. I agsin tried to flash recovery and this custom rom over Indian rom then everything works very smoothly but voice search. It fails with error "failed to open mic". Any help to fix this error.

[Android Software Development] vijay0567:
looking for the indian version.

---------- Post added at 06:49 PM ---------- Previous post was at 06:44 PM ----------

BTW the issue is that the screen has gone blank with just the letv logo glowing dimmly, on pressing power it glows bright and after few seconds back to dim. any suggestions welcome since leeco has almost stopped operations in india, buyers beware.
[Android Software Development] ranga:
Sorry, I only have US version with me.

Did you try factory resetting the TV?

Put TV OFF ; Press Vol + and Vol - and Channel + and Channel - and Power ON using remote.

If that doesnt work, try entering the recovery mode and wipe data and cache.

Two ways to enter the recovery:

- If you have physical buttons on the TV then just press and hold Vol+ button on the TV.

- If you do not have buttons on the TV you can use remote. Press: SETTINGS, VOL+, VOL-, CH+, CH-, POWER
[Android Software Development] vijay0567:
Yes I have been trying both factory setting and recovery mode, but the screen stays black. The logo lights up on pressing the power button and dims after few seconds. At times the logo continuously lights up from bright to dim and back on which i have to switch off the mains. This is blank screen issue has been raised by other patrons on indian lemall forum.
[Android Software Development] vijay0567:
Can you pls upload the US version, I would like to try it out, and I'll post the outcome accordingly.

[Android Software Development] egzthunder1:
It sounds like a hardware issue rather than a software one. I would try and go for a warranty repair if you still have the option.
[Android Software Development] vijay0567:
After factory resetting, somehow managed to get the TV working. But my situation has not changed at all. The screen is muddled meaning one has to squint ones eyes to read the screen and the sound has yet not returned. Somehow managed to update to the latest firmware OTA but situation has not changed for better. So is it software or hardware.

Hi [MENTION=6810881]dipcore[/MENTION], I am on Custom ROM provided by you.

Can you share any update to your custom ROM to tryout.
[Android Software Development] vijay0567:
No picture, no sound is an hardware issue. Main board seems to be the culprit, hoping the technician can repair the board.

Blank screen after OTA update to eui 5.8_517

Super3 X55 screen has gone blank after upgrading EUI to 5.8_517. Tried to run recovery but it starts and then displays an update failed error. Please help.

QUOTE=dipcore;71091281]

Recovery for LETV Super TV X3-50, X3-55, X3-55Pro, X3-65, X3-65Pro​

The recovery is based on generic aosp recovery. Signature checking is completely disabled, so you can flash any .zip update. The responsibility of what are you flashing is entirely on you.

The main problem was - the recovery cannot get assess to the TV screen. I wrote a lot of code to make fbdev working.

Successfully tested on:

x3-65 (Super3 Max65)

x3-55Pro (Super3 x55Pro)

x3-55 (Super3 x55)

x3-50 (Super3 x50)

How to flash recovery?

- TV is off

- Put LetvUpgrade928.bin from the archive to root folder of a usb drive and insert it to the TV

- Stay in front of the TV and point the remote to the center of the TV and press: SETTINGS, VOL+, VOL-, CH-, CH+, POWER (each button should be hold during 1-2 seconds, so no rush)

- TV will boot up and you'll get a blue progress bar. After flashing the TV turns itself off.

How to enter recovery mode?

Two ways to enter the recovery:

- If you have physical buttons on the TV then just press and hold Vol+ button on the TV.

- If you do not have buttons on the TV you can use remote. Press: SETTINGS, VOL+, VOL-, CH+, CH-, POWER

Is it US version of the TV?

5.8_517 - is it US or CN version of the ROM?

I believe you just need to flash the recovery again. The stock ROMs overwrite recovery partition.

I believe it is the IN or CN version as the TV was purchased in India. You have provided 3 versions of recovery. We only use the latest one right?

I had the same "no upgrade package" message. To fix, I had to go back one screen (from that message), unplug the USB drive, plug it back in, and then try to access the USB drive again and the package showed up.

In some cases the no upgrade package screen appears if the unit is no formatted in fat 32. I have this problems with a usb formatted in ntfs.

Dip i send you a pm. I cannot install the latest update 10alpha. When the tv boots up, appear the letv logo for 20 seconds and shutsdown.
[Android Software Development] ranga:
Same issue here, trying to install 10alpha. TV boots up, logo is on for 20 or so seconds and shutsdown. No error message shown. I tried factory reset, installing the previous version using the LetvUpgrade928.bin but it doesn't recognize the file. Only thing I can do now is access recovery menu and nothing else.
[Android Software Development] dipcore:
Here is a solution:

1. Install 0.0.10alpha

2. Install tvservice update https://drive.google.com/open?id=0BzCElQ6GM7IOX2dJU29wVVhsaGc

3. factory reset

4. reboot

5. first boot can take 10+ minutes
[Android Software Development] ranga:
The issue persists. The only way to get it to boot to TV is to reset it to stock. I even tried factory reset it multiple times. Please let me know if I can capture any logs and send it to you.

How did you "go back one screen"? I put the USB drive in the 2.0 slot. I turn on the tv. I press Settings, Vol Up, Down, Channel Down, Up, Power. The red warning comes on. I've unplugged the drive and placed it back in a couple times. Nothing. I pressed every button on my remote to try to get it to refresh. The drive is FAT32. I've used several drives to do this.

dipcore, is this because I am on your first firmware? If so, how do I flash back to the latest stock?
[Android Software Development] ucf713:
The buttons on the side of the TV still worked for me after I saw that message. If they are not working for you then you might be experiencing a different issue from mine.
[Android Software Development] ranga:
Thanks dipcore!

I am able to finally install it. I downloaded the files again and used a different USB drive. Not sure what the previous issue was, but it worked this time.

The one issue I am facing is that the TV is not scanning any OTA channels. Anyone else facing this issue?
[Android Software Development] dipcore:
The TV application is from CN firmware, they are using different digital TV standards (not ATSC).

I built MStar stock tv application which works with all tv standards. It has a bit strange UI, but it allows to scan channels. It also has channel list to quickly switch channels.

Hi dipcore. When you release the version with android tv support? I have the latest version, everithing works fine

Enviado desde mi Z2 Pro mediante Tapatalk
[Android Software Development] Michaelandhistab:
Hi Dipcore, I tried punching in "settings, vol up, vol down, channel down, channel up and power" but my TV just turns on normally. I've placed bin file into the root folder of my thumb drive in FAT32 format, and when my TV is on, I can see the file in File Manager. I've tried both the usb2.0 and 3.0 ports.

And to make sure it wasn't just my clumsy fingers, I tried the factory reset code "settings, vol up, channel up, channel down, vol down, power" and it worked the first time. So I'm thinking my TV just might not be recognizing the bin files. My TV is running EUI version 5.8.056S_0413, and the hardware version is H5000 if that makes any difference?

Thank you for your time. Cheers.
[Android Software Development] dametzg:
Based on your EUI version, it looks like you have an X4 TV. The recovery and ROMs here are for the older X3 TV's only, and won't work on the newer X4 that you have.
[Android Software Development] Michaelandhistab:
That's strange. It's definitely an x3, and it says so on the device info page. Perhaps if I downgraded my EUI version, I can then install the recovery?
[Android Software Development] dametzg:
Sorry, non-US TV then? I keep forgetting the other X3's are more updated than what we got here in the US. LeEco left us on 5.0.052. Hopefully dipcore can help you figure it out.
[Android Software Development] Michaelandhistab:
Yeah, it's a TV from Hong Kong, so I'm guessing it's the Chinese version.
[Android Software Development] dipcore:
1. Make sure you have X3 model

2. What remote do you have? Older one has numeric keys, in that case you need to press:

3691 POWER

or

3692 POWER

[MENTION=5042294]Michaelandhistab[/MENTION]

X3-40 and X3-43 models have android 4.1 or 4.4 depends on firmware version.

X3-50-55-60 models have android 5.0.1

X4 models have 6.0

So you can run android settings, if you have access to it, or install any apk which shows system info. (ie cpu-z http://www.apkmirror.com/apk/cpuid/cpu-z/cpu-z-1-23-release/cpu-z-1-23-android-apk-download/)
[Android Software Development] Michaelandhistab:
Thanks, Dipcore.

I just tried the 3691 code and it worked. It's funny how both the 3692 code and the "settings, vol up, channel up, channel down, vol down" code both work for factory reset, and only the 3691 code work for flashing.

Thanks for that. Have a great weekend!

It's looking for an update.zip instead of the bin file for some reason. Should I zip the bin file and rename it update.zip?

Hi,

LeTV Super3 X55 owner in India here with a System Version 5.8.057S_0517. Has anybody tried the ROM on this model in India (ideally with the above system update?)

Also given that Leco is in big financial trouble, it would appear that their service centers may be on the way out. Granted that this procedure is risky anyways but at least the recourse of paid repair was possible earlier. Has anybody bricked their TV with this?

Thanks
[Android Software Development] dipcore:
That's x3-40 model.

You do not need to rename .bin file

Ok, I figured that out, there are 3 key sequences on old-style remote:

1. Flash bin file: 3695 POWER

2. Flash zip file (or enter recovery if it's installed): 3691 POWER

3. Factory reset: 3692 POWER

So try to use #1. Let me know if it worked for you.
[Android Software Development] Michaelandhistab:
Thanks for the reply. When I tried the 3695 code, the TV turns on and the screen stays blank (I can tell the backlight is on). I left it for about 15 mins and it didn't do anything.
