F.J.V uploaded the stock recovery here: https://xdaforums.com/le-pro3/leeco...ment--and-mods/stock-recovery-lex722-t3686356

You can use CrisBalGreece's tool to flash the stock recovery: https://xdaforums.com/le-pro3/leeco.../twrp-recovery-multi-tool-zl0-lex722-t3702703

Unfortunately there's no safe stock ROM for this device. Usually going back to the stock ROM brings the stock recovery back, but most x722s out there have custom vendor ROMs. Plus, if you flash the stock ROMs for this device through TWRP, you'll lock the bootloader down completely. And the only way to flash the stock ROMs is through the stock recovery... you get the picture.

I wouldn't bother with the stock recovery at all after installing TWRP. Because TWRP is way better and going back to the stock recovery might end up being a pain. I can't think of a single scenario why you'd want to return to stock on this phone since no one cares for having a stock LeEco phone (seriously, it'd be stuck on Marshmallow, a nearly three-year-old OS). If you don't care for eUI there's no point in backing up the stock bootloader. Even if you're reselling the phone, trust me, no one wants or cares for stock LeEco software. It sucks.

Just make a Nandroid backup of your vendor ROM if you ever want to go back for stability reasons. Most custom ROMs for this device are buggy and don't have as good a battery life as the vendor eUI ROMs, sadly. That's why I'm still on my debloated vendor ROM from Banggood. My game (FGO) runs surprisingly well and battery life is never an issue. I'm able to play for hours straight without much of a battery life hit.

Well, maybe buggy, but what isn't. I got one ROM for X722 that is good (for me).

Is it possible for me to install this official rom by twrp?
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] ScroopyNoopers:
Boy, it's a good thing I came across this post! I wouldn't wanna tank this new beautiful phone, a steal at the current price btw.

I want to upgrade this phone to lineageOS so I've been doing my due diligence to not totally mess it up lol

The phone is from vendor banggood and is running EUI 5.8.020S, firmware 'WIXCNFN5802001232S release-keys'.

From the thread I gather that this vendor ROM should be able to flash TWRP recovery just fine, but when I connect phone to pc and run "fastboot devices", it returns nothing. "fastboot oem-devices" return nothing.

"adb devices" command returns the connected device fine.

Only when I run "adb reboot-bootloader" can I run the above fastboot checks, which then returns that my bootloader is unlocked.

Also, there is an "unlock pin" required to unlock the bootloader in the settings > developer options.

My worry is that I will flash TWRP recovery and that something will go wrong with recovery, making it impossible for me to fix via PC fastboot recovery flashing (since the phone has to be booted into recovery to be able to access fastboot via PC in the first place, for some reason)

Is there a way to backup the current recovery? Has anyone else played around with this particular build?

Any help from the android gods would be much appreciated (^_^)

Edit: OK. I went balls to the Wall and booted into that TWRP recovery. So far so good.

But now my screen locks and I can't use TWRP even though I can see the interface, the screen locks. I have disabled screen lock in OS and still it's locked.

*Edit of the edit. To solve the TWRP 3.2.1 screen lock issue, you need to cycle into recovery twice. DONT boot into OS first. Go into recovery, TWRP will screen lock, power off, then volume - and power button it again. Should be OK. Eh, ya live ya learn.

*Note to self. Bootloader and recovery are NOT interchangeable concepts lol. Bootloader is more akin to a PC's bios and custom recoveries are more like PC recovery partitions.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] regepower:
You must not install TWRP, just boot from an File via Fastboot. Put the twrp image in the folder where fastboot is located an enter fastboot -boot [IMAGE.FILE]. Your phone must be in fastboot mode.

Twrp will start and you are able to make an backup from the existing recovery. I install my custom roms without installing twrp with this way.

[LeEco Le Pro3 Elite (Model x722) Guides, Developme] ScroopyNoopers:
Hi Rene.

Thanks for the reply. I already replaced the stock recovery. This is fine because I do not plan to go back to any official or vendor ROM anyway.

Also, if I want a stock ROM or recovery, I have already seen links to those on these threads. LineageOS 15.1/14.1 is glorious though, I won't be returning lol Can't decide which one to use as final.

Side note. From these threads, I have been able to revive an old ZTE Nubia Z5s I thought I bricked out back in 2015 on my first ill-faited flashing attempts. This nubia z5s is now FLYING on lineageOS 14.1, it's night and day difference from the old stock ZTE ROM. I wouldn't even have gotten a new phone it is that good lol

Thanks to all of you fine gentlemen and ladies who support these threads. Your inputs and vast reservoirs of information here have made tweaking this phone fun, informative and far less daunting lol

I'm so comfortable now, I'm even attempt to breathe new new life into another old, sh*tty phone. A huawei P7. Although this phone seems much more locked down.

Thanks again everyone.

Hello,

I follow the procedure and I stick just after the firmware downgrade to 01D (previous banggood 20s but TWRP with lock touch screen)

I want to install the 20s firmware with no TWRP lock. No success.

In fastmode, I install the 20s unlocked but when I look inside the phone properties the version is still 01D.

I don't want to install the lineageOS with this version of the firmware because in the first line it 's mentionned : 20s mandatory.

thanks in advance

Chaouche95

edit : I succeed because I used the X722-5.8.020S by Batyan.zip. not with the version indicated at the beginning of this topic.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] ScroopyNoopers:
lol read the posts dude.

1) TWRP lock issue is already solved. just reboot into recovery again after it locks up the first time

2) You cannot flash stock firmware with TWRP. You will need to go back to stock recovery to do that -- run 'adb reboot bootloader' then 'fastboot flash recovery Original_Recovery.img' THEN flash the 20s firmware.

The real question is though.. why in the seven hellz would you want to go back to stock vendor firmware? ¯\_(ツ)_/¯

LineageOS is the balls. Leave 01D, just boot into TWRP and install lineageOS. you will like it.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] sk8223:
You can flash vendor 20s or 26s ROMs through TWRP. You most likely got a vendor ROM on your phone that contains multiple languages and no Chinese apps. That's a vendor ROM. In any case, everyone should read the sticky. Phones from Gearbest, Banggood, Geekbuying, etc. will have vendor ROMs. Phones from Aliexpress may or may not have vendor ROMs.

I've listed the one stock 20s firmware you shouldn't flash there. That's the Chinese one you'd get if you bought your phone from a China-only vendor. Like LeEco itself.

As for 01D, I'm not sure if you can flash that through TWRP or not. If it contains the LeEco recovery, then you can't. Always make a Nandroid backup of your eUI software before flashing anything if you want to go back to stock for whatever reason (commonsense.jpg). The 01D firmware is buggy and is only meant for people on stock 26s... but it won't harm your phone if you downgrade to it if you're on 20s. Performance just isn't as good as vendor ROMs, IMO.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] DLP357:
How much screen on time do you get with the 20s ROM? Mine is only 4h deleting a lot of system services and without GPS activated...
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] sk8223:
This isn't a good ROM for performance. It's meant for development only. So expect bad battery life and the like. You're supposed to use this ROM as a stepping stone for flashing other ROMs. If you want a stable eUI ROM, you should have made a Nandroid backup of the eUI ROM that came with your device.

The eUI ROM that your device came with was most likely a vendor/shop ROM with multiple languages and Google apps. Which x722s with stock OEM eUI don't have because the phone was only released in China.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] DLP357:
Thanks for your reply. Did anyone make a backup to share with others? Or maybe suggest another eui ROM?
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] sk8223:
No, not yet, but you can message some active members on the forum and maybe they'll send you one. I'm planning on making one and uploading it here if and when I root my phone. I'm not sure yet as I plan on selling my phone and don't want to deal with complaints, lol. I bought a Redmi Note 4 and am waiting for it to get to me.

CrisbalGreece has an eUI ROM here you can flash. It's a lot more stable than this one.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] DLP357:

[LeEco Le Pro3 Elite (Model x722) Guides, Developme] sk8223:
Why bother with eUI though? Flash any other ROM. Like LOS 15.1 by codeworkx. What's keeping you on eUI?
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] DLP357:
Well, I always used aosp/stock ROMs on my phones but I got a little bit bored of the same UI so I wanted to change.

Hi everyone,

I was having trouble installing the 20s version.

But when it started writing data, the command window would exit abruptly and the phone automatically rebooted to a fresh '001 Dev' rom.

I panicked a little (a lot). But Google is our friend

Two fixes appeared.

As an eager amateur i did not diagnosed the fault and did them at the same time.

I put the adb files on the same folder as the .bat file AND changed the cable.

It solved it for me and now im ready to explore the roms available for this phone.

It seems no one had this problem, but i hope it helps someone sometime in the future.

You should've read through every thread here thoroughly before attempting anything. I have no idea why you choose Kingroot of all things to root the device... did you not see the stickies I posted here and in the General forum?

The reason the ROM's performance is janky is because it's a 01D (Developer) ROM. It's a stock development ROM. If you want good performance, switch to a custom eUI ROM. What you actually should've done was read through the root/bootloader unlock thread in this forum, unlocked your bootloader, made a backup of your vendor ROM (if you ever want to return to an eUI ROM with good performance) and moved on.

That requirement has since been debunked. As long as you're on a vendor ROM, no matter the eUI version, it's safe for you to unlock the bootloader straight away. Again, I wish you read my sticky. I guess I should've given it a better title, but the stock 26s bricking situation was somewhat dire at the time.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] tylerciggy:
Well, I haven't tried to root/flash a phone since several years ago and back then, kings apps were safe to use. Now I see everything is different and more risky.

I didn't flash the developer rom, just tried to apply the update patch. Although I haven't had the time to touch the phone today and I don't know if it's only "janky" on the playstore. To be more accurate, it needs some time to begin downloading an app (like half minute).

I still maybe have to reflash the phone, because it is kinda rooted without root (I can still see and edit build.prop in ES File Explorer, but there is no magisk installed).

I tried to read several threads but the information is so scattered, this thread had more answers to my questions than the other ones.

Being bold, the only real issue I had was when I installed the magisk module that soft bricked my phone, the root thread was fairly good enough to make it done. Now I don't care much about stereo sound (not yet), but more on having a working Gcam App.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] sk8223:
In any case, reset your phone, read the sticky and follow the instructions in the rooting and bootloader unlock thread. You can stay on your current 20s vendor ROM or switch to another ROM after that. Just be sure to make a backup of your vendor ROM in TWRP.
[LeEco Le Pro3 Elite (Model x722) Guides, Developme] tylerciggy:
I don't know why I feel that you think I didn't read anything at all.

I did read stickys and I didn't find anything about flashing with King/Kingo apps.

I did follow the instructions of rooting and bootloader, proof is that I could root mine without any issue.

The only mistake I did was not making a backup of my vendor rom.

I would already flashed the bantyas rom, but I'm still not sure if that "update patch" really makes it a vendor rom or is just an improved rom. Although I wouldn't even care if I can restore the stereo sound, but I still haven't got an answer of ANY of the questions I made.

I'm not flashing it yet because I still have the feel that I can restore this rom by just redo the changes that has been made so far.

So guys... i need help. my phone is with a HARD BRICK, my phone does not start, it does not go into bootloader mode, it does not turn on, it only stays on the black screen. I've found a way to fix it, but I need your help. I need someone to flash the stock ROM of LEECO LE PRO3 ELITE (X722) and do the following tutorial, please, it is the last option I have. If all goes well, I'll post the tutorial here on the site to help others with the same problem.

PLEASE, LOAD THE FILE TO THE CLOUD AND POST HERE.

TUTORIAL:

Format your external MicroSD card with “exfat” system file, and the size of this SD card should be morethan 16 GB , which is the size of the whole partition.

Do a full factory reset, meaning wipe your cache, data, and internal storage using either CWM, TWRP, or PhillzTouch.

Insert the SD card to your phone and connect your mobile with ADB, type:

adb shell

su

dd if=/dev/block/mmcblk0 of=/storage/sdcard1/backup.img bs=512 count=30535646

The size of the “backup.img” is around 16 GB, However, if you compressed it, it would be around 2 GB.

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
I don't see how changing the MID would affect the boot partition. But not enough info to completely assess. Do fastboot getvar all, and post the results (delete IMEI and serial number).

And what was the original MID, and what MID did you change it to? And what was the intent in changing the MID?

Post the exact cmd prompt commands, if you can (screenshot is probably the fastest and easiest way).

Assuming there were no other mods you applied at the same time, or any other files flashed?
[One (M8) Q&A, Help & Troubleshooting] Tenor:
I couldn't believe that something like this was possible to happen :D.My intention of changing MID was to set it to the same MID as it was needed for RUU.I've not done any flashing either.Interesting thing is that,after booting again,i got ,,To Start Android,Enter Password" and also,from TWRP,Internal Storage capacity went to 0 MB.I had TWRP Backup of my recent ROM,so i formated Internal Storage,used TWRP Restore and now it's all okay.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Yeah, but what was the actual MID that it was originally? What specific MID did you change it to? And what RUU did you intend to flash?

Again, post the output fastboot getvar all, so we can see more info about the device.

Reason I ask, these things, is that some versions of the M8, it's not safe to change the MID and flash another M8 version's RUU. This should not have caused the problem you describe (that I am aware of) but I'd like to check anyway. Just to be safe, and make sure you aren't trying to do something that will damage your device.

I'd also like to see the specific commands used, as also previously requested. I know you said your commands changed the MID correctly. But I also don't see how else boot and data partitions were corrupted (which appears to be what happened).
