Unable to Flash Dipcore Recovery

Hello,

My tv is Super3 x55 EUI version 5.8.048S

USB drive formatted to FAT32 and changed to mbr... still no go

I have tried installing Dipcore recovery letv_recovery_v0.0.3.zip 10.19 MB.

but I am getting error message saying that "No upgrade package in usb"

I have downloaded similar files with the same name and different sizes.

1. 628 MB

2. 917 MB

Please let me know which size version to use to install the recovery only.

Thank you
[Android Software Development] koolanil81:
I had also faced the similar issue, i was seeing a green bar and it disappeared. I was unable to enter recovery screen.

Then i tried resetting the TV and it worked this time.

I could install the zip file and Google play store was there.

But what i felt was,

1. The EUI version which i had was updated one and that was way better than factory reset version.

2. The play store is very old and cant find all the apps e.x. i could not find NETFLIX. I had to install APPTOIDE TV to install NETFLIX.

3. The UI after play store has become slow, laggy.

4. Try to take backup of current version of ROM (i dont know how to do it, if u could share that with me)

5. I want to go back to earlier version (without play store) but i cant :mad:

Hope this helps.

Update.zips fail but only .bin files work.]

I am able to install Dipcore custom recovery but cannot install any zip firmwares.

Tried, Indian, Chinese, and US .zip roms all of them fail in the middle of the installation.

This is the 2nd tv X3 55inch, the other tv is working fine with customer recovery & custom rom.

I deleted the cache partition, Did it mess up things!!!

Please advise

did you try remove additional apps you may have installed which would be consuming storage space?

If not installed any then you can get a list of all apps taking space to identify that should help take decision.

Hi, i made a mistake for my umax85 that used reset remote combination after install a new rom, it won't boot and just blue light on. It won't take recovery combination on remote, please help !!! Thanks !!!

[Android Software Development] dingdongyo:
x3-55 pro user here

I'm finding that i have to reflash with the recovery every time i flash with anything else in order to get recovery working again. is that normal?

the custom rom didn't work well at all on my TV. it constantly displayed a "running low on space" error even though disk and memory both had plenty remaining. none of the apps i tried to intall worked.

i can't figure out how to flash with the Chinese update. I've seen that there's a way to enable HDR using the Chinese rom, but every time i try to flash it, it doesn't work. the TV will show a chinese loading screen for about a minute, then shut off. i've already tried the method of flashing, flashing recovery again (because recovery stops working everytime i flash something else), doing a factory reset, and flashing with the Chinese zip again. still doesn't work.

more generally, i can't get any .zip to flash correctly. the only ones i can get to work are recovery files labeled LeTVUpgrade928.bin. yes, i understand the different button sequences and i'm using the SETTINGS VOL▲ VOL▼ CH▲ CH▼ POWER sequence to enter recovery to run the .zip files, and it doesn't work.

has anyone got it working? can you enable HDR in it? can you share your comprehensive step-by-step?
[Android Software Development] dingdongyo:
i think what i really need is the Chinese version of the rom as a LeTVUpgrade928.bin file. All i can find from the archive of the website are .zips. If anyone here has the Chinese .bin and would be so kind to share, i would appreciate it. thanks!
[Android Software Development] Waqasmgl:
hello friend .. i have copied it inusb and done all procedure but it is giving an eroor of. “ no upgrade package found in usb”

please help !!!
[Android Software Development] dingdongyo:
Is this thread dead? I tried emailing dipcore directly, but I'm not confident he will want to engage. I'm just so frustrated I can't make this work when it seems like so many others are flashing .zip files super easily. Like there's something stupid I'm missing.

This is a picture of the on screen text after attempting to flash a .zip rom. The TV doesn't work after this. I can turn it on but it just shows a Chinese loading screen for a minute and shuts back off. I have to flash a LeTVUpgrade928.bin file after this to regain any functionality (including boot to recovery). Are there any clues in here?
[Android Software Development] dingdongyo:
you need to extract the LeTVUpgrade928.bin file from letv_recovery_v0.0.3.zip. then place the .bin file on the root of a USB drive. insert into the tv with the physical switch off. then hold OK and switch the tv on. wait and you should see a green bar as the custom recovery is flashed. turn the tv on using the remote by using the SETTINGS VOL▲ VOL▼ CH▲ CH▼ POWER button sequence (hold each for about 2 seconds). the custom recovery should then boot.

i also have both size files you mention from two different sources, and i was able to flash either successfully. i'm not sure what the difference is, honestly, since i'm only trying to flash EUI 6.0 in order to activate HDR. but in any case, both of those files worked for me.
[Android Software Development] dingdongyo:
maybe try with a different USB stick? make sure it's formatted FAT32? there isn't much detail here to determine what went wrong.

try turning the physical switch off, holding the OK button on the side of the tv, and flipping the switch on again. see if that does anything different.
[Android Software Development] yuhu93:
Thank you for answering my questions so thoroughly.

And holy cow! A rom with those features would make life so much better compared to the current stock version. I would love to contribute/test if need.

Is there any way to include the option of keeping CN/IN content though? Or is that pretty much tied in with the stock interface?

I have a x3-55 Pro and have tried multiple times to flash the bin file but every time the progress bar shows up, it errors out. It says that it failed to install the update and that it will restart the device (but it never does).

Any ideas?

I am on 5.0.052S_1216
[Android Software Development] dipcore:
I have x3-55pro US, but it works on x3-50, x3-55, x3-55pro, x3-65. (Tested and confirmed working on US, IN, CN versions)

Basically there are three different key sequences:

1. To flash .bin: SETTINGS, VOL+, VOL-, CH-, CH+, POWER

2. To enter recovery or flash .zip: SETTINGS, VOL+, VOL-, CH+, CH-, POWER

3. To do a factory reset: SETTINGS, VOL+, CH+, CH-, VOL-, POWER

It seems like you are using #2 instead of #1. They are very similar so make sure you are using #1
[Android Software Development] egzthunder1:
You are absolutely correct. I think I am using #2 as opposed to #1. Thank you for pointing that out! I will try that again and report back. BTW, you mentioned that you were working on a newer version of your ROM, right? Looking forward to it!

Thanks again for your help on this! I've been waiting to get root on this thing for a long time... Gapps, here I come!
[Android Software Development] egzthunder1:
Thank you for the tip about the proper flashing of the bin file. It worked and now I am on your recovery. Having said that, I just tried to flash the SuperSU zip via recovery but it fails to flash it. I believe it was error 255. I will try again and double check the number.
[Android Software Development] dipcore:
Just to confirm, did you flash zip file from https://xdaforums.com/android/software/zip-letv-super-tv-x3-55-x3-55pro-x3-65-t3592193 ?
[Android Software Development] egzthunder1:
Yes, that is the one I flashed.
[Android Software Development] dipcore:
show me your logs from /cache/recovery folder pls
[Android Software Development] dipcore:
Could you try to flash two testing files:

1. View attachment update_test_install_app.zip and reboot to android. You should have a test app letv_led_on.apk installed

2. Then flash View attachment update_test_uninstall_app.zip The test app should be removed.
[Android Software Development] egzthunder1:
I will try to grab the logs shortly. I did try to install the zip and it errors out as well. However, this error complained about the drive being in FAT (fat32 actually).

How to revert back to everything stock on letv super3 x55?

Installed custom firmware

Its too Laggy

and too much advertisements

and rom is showing 4GB only(inbuilt is 8GB it should show 8GB)

want to revert back to stock Indian rom

Help!!!!!!
[Android Software Development] dipcore:
I'm not sure what firmware did you install. In my custom ROM, there are no ads at all. I removed it all. That was my task #1.

Only system partition is packed to my firmware, nothing else. So it does nothing with other partitions (no re-partitioning, no formatting, just nothing). If you had 8Gb before flashing it then you should have it after. For instance my TV model has 16Gb, and it is showing 16Gb.

You also need to make sure you did factory reset after installing the rom.

If you want to flash back stock Indian firmware just download it from the IN website and flash as any other ZIP file. You can use my custom recovery to flash it, if you wish.

i spent many more hours trying to install the chinese eui 6.0 rom on my tv and still got pretty much nowhere. but i have a couple different requests that may help me? (i have no idea at this point....)

- first, i found this chinese blog post from another developer that has a link to a zip file containing some different upgrade .bins, and i'm hopeful that one of them would work. unfortunately the download link is from cloud.189.cn, and i cannot figure out how to download the file without a login. i can't figure out how to create a login either, or contact the guy. any ideas?

- i found that i can flash the US stock rom .zip successfully using the custom recovery. from that stock rom, i can go to "system update" and choose one of the chinese upgrade rom files. it looks like it recognizes the file and can actually finish the upgrade process. but after the upgrade, the tv shows the same behavior as before: it will show a chinese loading screen for about a minute, then turn back off.

- i found this other blog post with a link to a cloud folder full of roms and packages, but his chinese rom file also didn't work for me.

- i noticed that between May 2019 and June 2019, the download links for the 6.0.057s and 5.8.052s versions of the firmware were taken down from the official website. the download links still work if the web.archive.org prefix is removed.

- i tried installing the engineering .apk on the US version of the rom and it works, but i can't enable HDR in it. there's a place to update HDCP, but i don't have a key or update file.

can anyone offer any help here?

[Android Software Development] ravinag:
@dipcore

LETV x3 55 seeing blank screen with images coming in backgroud as shadow ghost images. I have tried the LetvUpgrade928.bin, but still showing blank screen.

Steps used

1) copy LetvUpgrade928.bin into USB formated with FAT32

2) Insert to White USB port of TV to boot

3) Used Settings, Vol +, Vol-, CH-, CH+ and press start button

4) The Letv Logo light blinks continuously and shows language and other menu's in shadow/ghost behind screen very light, Even the boot music does not come.

Please tell me what to do to fix it.

Sorry, to me it really does sound like something has gone bad with your TV's hardware. Especially if you've restored the ROM.

Sorry if this is slightly off-topic, but this is seems to be one of the last few places on the web that has any X3-55 discussion. Anyone able to successfully change their inputs using Amazon FireStick 4K (or Max)? I'm running 59S, FWIW. TIA!
[Android Software Development] desihu:
As in you want to boot directly into HDMI port connected to fire stick?

That setting was under Settings > Home I believe... Been ages since I tinkered with this though.
[Android Software Development] ch0rtle:
Thanks desihu. No, not boot and default to a certain HMDI. Actually change the HDMI input being displayed on the TV using the Firestick remote. This would entail choosing the right TV setting in Firestick Settings. I am able to turn the TV on/off from the remote,and actually it does power the TV on using CEC. But i cannot change HDMI inputs from the Fire TV. The Max now provides an input button, but I don't actually have that device. There were evidently voice settings to change TV inputs, but I don't see them. I imagine it's a very, very narrow usecase. Tx. :)

What do you mean you cannot download the folder, as in you cannot see anything inside the folder? It has some firmware files and gapp files etc.
[Android Software Development] alber786:
Great work.

Can you provide access to these files? Your Google Drive isn't letting me download.

Also, is it possible to unroot and recover the system to the state as it was before installing recovery?

Is the STOCK ROM actually a modified ROM or the factory ROM?

Need your help
[Android Software Development] desihu:
@unknown31415 has already replied confirm that the access to the shared Google drive folder is open to all. However do ensure you use your Google account to access them. I can reconfirm that the file are accessible.

As for the second query, you would need to find the stock rom for your particular model to attain your goal. I don't think the stock rom is among the shared files.
