Can you tell more? Have efs good? What eui its working on default?
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] F.J.V:
The Rom is a development that only serves as a test. The recovery that installs is the official of leeco.

By fastboot you can install the rom you want, but my advice is to install TWRP, and with this the rom you want, unless you want to put an official rom leeco. In that case the flash by fastboot or with the stock recovery.

Greetings.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] MnMchill:
Guys here you have lot of custom ROMs, don't use stock one because it's old and trash:

https://xdaforums.com/le-pro3/development

Here is the latest TWRP 3.2.3-0 for up to Oreo builds:

https://eu.dl.twrp.me/zl0/

I have tried almost all the ROMs from above link and if someone need any help just ask.

For a beggining I would recommend you Lineage 15.1 build from 05.09.2018 because it's most stable, you can download it from here and just flash it in TWRP 3.2.3-0 with Pico Gapps and Magisk 17.1:

I have the problem of memory.

the phone does not turn off
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] MnMchill:
Probably because it's development ROM. Flash stock ROM and than do factory reset to recover memory and after flash Batyan 01D development ROM so you could unlock bootloader. After that unlock your bootloader and flash TWRP 3.2.3-0, flash 20s firmware and after that flash some custom ROM.

EDIT: As reported later there is no need to flash stock ROM to recover memory, just do factory reset. Because bootloader is unlocked in development ROM there is no need to unlock it, just proceed to flashing TWRP 3.2.3-0, firmware 20s and custom ROM of your choice.

Do we have to install "firmware-20S-X722-le_zl0" before installing Lineage OS? It's only 45mb

Which is the best ROM for battery life right now?

My device has been dead since June.

[LeEco Le Pro3 Elite (Model x722) Guides, Developme] MnMchill:
Yes, you must flash 20s firmware before flashing Lineage 15.1.

Did you flashed TRWP 3.2.3-0? Best battery life have Lineage up to 05.09.2018 ROM. You are getting that Vendor partition error because you are trying to flash new Lineage and it's treble so it's needs to be flashed twice to work and doesn't have good battery life and that will be fixed in next build. That's why I'm telling you to flash Lineage 15.1 20180905 and not latest Lineage 15.1 but you probably don't read so READ what I'm writing please.

---------- Post added at 09:47 PM ---------- Previous post was at 09:42 PM ----------

So you just did factory reset and your memory recovered, you didn't have to flash stock ROM to be able to recover memory, just to clear that?

As for your screen not turning of it's because it's development ROM. Development ROMs are not intended for use, they are for testing so flash some traditional ROM.

we're already 6 with the same problem in like 1 week. And i rarely saw this error. We all have the same simptoms... i was at the service, i have my phone opened, today i will talk with [MENTION=7672955]tsongming[/MENTION] again to try to fix (and also help you guys)

This is fcking interesting, for 6 guy the same thing happend on x722 in like a week, guys let's see form where it started. Did you had as base rom 30S ? Did you all had Blackscreen or AICP ?
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] tsongming:
Okay, I just got home from the doctor, whoever texted me, you didn't mention your name. My phone blocks unknown numbers, so I just saw the text.

This issue is not 30s. My mom has 30s on her phone for a month with zero issues. The temperature stays low, I haven't seen any issues with her phone, she now loves EUI.

My guess is that it's something with Pie and over clocking, permissions, and screen brightness/drivers.

I have noticed that with Pie, that permissions are sometimes/often broken.

For example, Viper works and then a few hours later it doesn't. My paid Google apps, have lost the proof of payment permission symlink multiple times. I reflash Gapps its fine and then goes back to the same issues. Where it's fixed when I uninstall and reinstall the app.

I significantly underclocked my processor, and it still uses the highest frequencies. Etc. But, with AICP there is no heat, so its surely be safe.

With the huge amount of people who have experienced recent hardware issues, I am going to stop using pie until this is sorted out.

Of course, this is all just speculation, so I could be completely wrong.

But something is causing these problems with such a large group of people.

Maybe part of these issues could be a Magisk or Gapps issue?

Another question that I have is:

Is the pie video drivers /brightness setting of 15,000 pushing our devices to its GPU limits?

Yes, I know the LeEco increased their brightness on 30s. But it's on Marshmallow, with a tamer kernel.

Is this too hostile or out of line? Who knows... Not me.

If you currently have these issues.

What were you using?

Be specific. Maybe we should create a separate discussion thread for this.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] F.J.V:
It is true that there may be three similar cases, but it is also true that there can be three hardware failures.

That I know the rom 30S is just a ROM, does not change the firmware, there is no 30S firmware for X722, I do not think this rom has anything to do with it.

But your case is different, nothing works.

Sorry I can not do tests, I need my phone permanently operative, maybe I need to add some more partition to qfil, but usually the qfil works like in any other terminal, and have recovered terminals that have come to brick in different ways, as well that the most probable thing is that in your cases there is a hardware failure.

Usually a brick occurs when making a defective software change, but in your cases the brick has appeared "without software change" therefore it is most likely a hardware failure.

It is not the first time I say it, but anything in this world can suddenly be broken for no apparent reason, and in those cases no software will repair it.

Even a high-end phone can be broken in a short time, but usually it covers the warranty and almost nobody finds out, but it happens.

I think it can be a problem distances, I'm from Spain, if someone can give me the terminal to try with him I would try to modify qfil and try, with mine I can not.

Greetings.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] D1stRU3T0R:
Allright, I understand. It's strange, because: It started happening only in the last weeks and 2. we all have the same simptoms, and one guy only talked at WhatsApp, other guy only disconnected the phone from PC, and me only discharged it. But same end. Interesting tho :( I tried again, I can't install latest qpst on windows 10, qfil with erase all option not responding, and oneflash gave this error:

[LeEco Le Pro3 Elite (Model x722) Guides, Developme] F.J.V:
What tsongming says seems to me very successful. Maybe some roms are forcing some frequencies, and some terminals end up failing, which leads to the issue of hardware failure.

Also in these cases that the qfil works, but nothing is seen, we should rule out that the screen has not been damaged, because if you pass qfil, and it works fastboot, there is no brick, in this case the screen may have broken down , or also, that the graphic part of the processor has been damaged.

[LeEco Le Pro3 Elite (Model x722) Guides, Developme] Cheoooo:
Yes, I used 30s for two weeks apparently good with any heating problems or slow performance.

After I installed Skype and reciving a call it turns down and kept hard bricked, I tried several times Qfil without success.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] D1stRU3T0R:
It is working again! I opened the phone and tried at my home PC, and now it's working.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] F.J.V:
Well, at least this can reaffirm that there is a blockage that only disappears when the battery is disconnected.

Now we have to find out if your problem is hardware.

By the way, its symptoms with qfil are as if it were not an X722.

I do not think you can modify the signature of the terminal, but try the qfil of the X720 to verify.

Is removing the batterie really the solution to the "sahara problem" ?
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] F.J.V:
:eek:

Who has said that?

There is no problem Sahara.

If the terminal is not broken, the PC is correct and the instructions are followed, the flash is done without problems.

If the flash fails, there is a problem with the pc, with the terminal, or something has not been done correctly.

In the case that you comment, there seems to be a problem with the terminal.

When you make this qfil, you relock your bootloader?

[LeEco Le Pro3 Elite (Model x722) Guides, Developme] thewell:
I have blundered my way through this - firstly when installing twrp, video tutorials stated to write ‘twrp.img’ and I couldn’t get it to work, till I finally found one that had only ‘twrp’, which worked.

Then when trying to install firmware 20S via adb I repeatedly had error message about no devices /emulators found. It seems the laptop I use doesn’t have them, even though I ‘think’ I installed them- I certainly went through the process! Anyway, my phone was recognised in platform tools, and I had already copied the files over so I just copied and pasted and it worked.

Although I am a ‘senior member’ , I am effectively a ‘noob’ and I have got through by chance rather than design, but I thought it worth mentioning that it seems that it can be done without the correct drivers. I do wonder if I have committed an error that might come back to bite me doing it like this, I am sure someone will tell me! Otherwise I am hoping this may help any fellow incompetents who may be struggling with this!

I plugged it in the charger there was no problem.But when i put the phone to charge for a second time, after 2-3 minutes it began bootloop and suddenly screen went black with fastboot available, but no adb.

I know that this isn't for this thread, but i didn't know where to ask for some advice. Also should i try installing stock rom with fastboot, and what commands should i use for that.

Saludos. Vi tu nick del foro de htcmania.

Tengo problemas entrando al modo EDL. Mi telefono solo vibra con cualquier combinación de teclas.

Hubo un momento en que pude entrar al EDL (ironicamente justo despues de instalar los drivers del qdloader mi pc detectó un dispositivo nuevo conectado), inclusive a un recovery primitivo y al fastboot, incluso respaldé mis datos. La cosa es que quise intentar revivirlo sin flashear todo el rom (solo flashie el devcfg.img, aunque lo hice con una version del x720 por error) y a partir de ahí no he podido volver a entrar al modo EDL, vuelvo a estar como al principio que solo vibra.

Cabe mencionar que aunque lo desconecté en multiples ocaciones (mientras hacia mis respaldos), nunca se reinició ni nada y cuando hice el flasheo ni siquiera lo desconecté, simplemente ya no quiso volver a entrar en modo EDL. Aún estoy por probar un tercer cable, pero no creo que vaya por ahí el asunto.

De casualidad tienes conocimiento al respecto ?

If your computer does not recognize the terminal, try another computer. If it is not recognized it is a hardware failure, and you cannot use qfil.

Please don't post any other qfil links other than the first one, and don't ask about qfil issues with those links, ask the link authors.

The qfil published by me is the first functional qfil, the rest are modifications or copies of it. The link works since I loaded it, it has never failed and I intend to leave it for a long time, please do not comment that the link fails or is down, because it is not true.

The qfil works perfectly with Windows 10, because I modified the faulty original with Windows 10, all the tests were done in Windows 10, if it doesn't work well, make sure you have administrator permissions and that it is in the root of the hard drive, as detailed in the instructions, or rule out Python issues, you don't need Windows 7 or compatibility or anything.

I have a LeEco Le Pro 3 X722 = zl0 and the screen wont turn on or the OS load.

Tryed with another battery etc does not help, but get EDL Mode started, but no fastboot etc.

I had unlocked bootloader, TWRP and Linegeaos installed with root and probably USB debugging also set before the problem started.

What is the best way to continue when I want to try to save/recover pictures and videon on the flash memory?

Does trying these unbrick methods always destoroy user data or is there possibility to do things in a way that saves the users data?

Exsample someting like tying to unbrick just the boot section or restore TWRP etc and use it to backup the whole flash?

Whan can be done and how?

Thanks in advance for all your help
