Well that's unfortunate progress.... Looks like I'll be trying to figure out which specific US firmware partitions need to be overwritten with their CN counterparts to unlock the bootloader. I spent half an hour last night backing up all the partitions from the 5.0.19s (short of the cache and userdata) update so I'll be able to do some testing somewhat free of the worry of botching everything.

Also, helpful tip to anyone that doesn't speak chinese booting the CN TWRP image for the first time, and having a second android device to work with... Google translate from the second device in live video mode from Chinese to Whatever you speak will do real time language translating on screen for you :) Makes switching languages much easier.

BTW, if I didn't say thank you for taking this leap yet, THANK YOU.

I'm setting up my repositories to start building an english based (and updated) TWRP image, hopefully I'll have something a little more workable tonight, maybe something that understands encryption a little better and doesn't require people to work from an OTG drive or wiping their userdata. This is all made more fun by the fact that macOS doesn't seem to recognize my device. Windows 7 doesn't either (I had to force an existing driver to install). This likely means they're using a very non-standard usb id. Fun times!

btw, I was never able to unlock the bootloader not even temporarily with new firmware
[LeEco Le Pro3 Guides, News, & Discussion] HewettBR:
Question, forgive me for being a little naive or off base but would it be possible to temp boot to twrp on the us rom Do a backup flash the CN file and then restore the us backup? I'm sure something would go wrong but just a though.
[LeEco Le Pro3 Guides, News, & Discussion] phidung3721:
Well you can try. But what do you think you can get out of it? At the end you will end up with US rom with chinese basebands. :confused:
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
You're welcome :good:

It's not looking good for band 12 on GrossoShop Rom. I haven't checked for band 12 on the stock Chinese Rom so I'll do that tomorrow.

I'm also wondering if the folks at GrossoShop can make a NON-HLOS.bin with band 12 activated.

It would be great if you can get an updated + English version of twrp working. I'm looking forward to that :)
[LeEco Le Pro3 Guides, News, & Discussion] HewettBR:
Just to get the us rom with root. Just tossing ideas out there since I come from Nexus phones so this is all new to me.
[LeEco Le Pro3 Guides, News, & Discussion] dr4stic:
Yeah... well, with the 5.0.19s update offering a partial (if only temporary), but official semi-unlock, and having the firmware components from the CN rom to play with, my next step is to see how little I need to replace in order to go from US ROM to unlocked hybrid US rom with chinese bootloader. I've got a friend knowledgeable on the msm8996 bootloader process guiding me through this. The device is a bit of a disaster implementation wise. The stock EUI rom is a bad target for proprietary blobs to use in an open rom like CM or some other CAF based implementation. It's likely my version will be using an open hal for the cameras that won't have any additional post-processing on the sensor output for sharpness cleanup and the like. The audio will likely also be a bit more basic, and there's a slight chance even the fingerprint sensor won't work.

But for now, I just need a kernel that works... and that's most likely gonna be easiest by building twrp. It's the easiest interface that leads to a working bootable image that doesn't require much more than storage access, graphics, and the touchpanel.

To everyone else, I have to believe that the 5.0.19s unlock ability was a mistake, and the accepting of the firmware without double checking all the signing on the OTAs was also a mistake. If you're on that firmware now, I'd advise avoiding updating if you have a desire to eventually run an open ROM. It's getting harder and harder to unlock modern devices unless manufacturers make mistakes. When you have a mistake, you stick to it.
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
I would assume it will be the same on Stock CN as the modem wasn't loaded on the GrossoShop ROM, only system, boot and recovery. Someone on stock US ROM needs to get a dump.

dd if=/dev/block/platform/*/by-name/modem of=/sdcard/NON-HLOS.bin

Or something like that.

I am on . 18s and just got the .19s notification. Should I not update yet if I am not ready to put the Chinese rom on since the temp is only good till reboot? Or can I still update and decide later if I want to switch the rom and root. Thanks in advance
[LeEco Le Pro3 Guides, News, & Discussion] bricky23:
Yes you can update, and still flash the Chinese rom later.
[LeEco Le Pro3 Guides, News, & Discussion] csyann:
Hi hondajohn88 and all others, thanks for your great try. I already updated to .19S, today I downloaded the 720 rom, renamed to update.zip, but failed to flash into 727, it shows corrupted, but still allow me to back and restart. So not working on .19S? comment please, thanks!
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
Hmmm...I believe I installed the x720 Rom after I updated.

Was it this Rom you installed? LE_ZL1_LEX720-CN-FN-WAXCNFN5801811021S-5.8.018S.zip?

Maybe try the download again. Did you use the Update feature in Settings and choose the Update package?
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
The rom on this site is the one that worked for me:

https://devs-lab.com/download-letv-official-stock-rom.html#LeTV_LeEco_Le_3_Pro_Stock_ROM

Give it a try.

The one from the Mega site also gave me the corrupt message.
[LeEco Le Pro3 Guides, News, & Discussion] csyann:
Thanks for ur prompt reply, very much apprecate it. the file I used was LE_ZL1_LEX720-CN-5.8.018S-fullota.zip, the link at #355 you first posted.

in file manager, I clicked the zip file, then selected upgrade.

let me try again! and could u please post another link for LE_ZL1_LEX720-CN-FN-WAXCNFN5801811021S-5.8.018S.zip?

Sorry the first one pointed to the wrong file. I'll edit it so it points to the other one.

Did the file from the link above work?
[LeEco Le Pro3 Guides, News, & Discussion] csyann:
yes, just did it, but why need password ? it shows " to start android, enter your password", I thought it's to set up a new password, but after I entered one, it shows wrong password
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
Is TWRP asking for password, or is the ROM asking for password? If it's the ROM, boot into bootloader and unlock it, then install TWRP, then wipe and reinstall the rom zip.
[LeEco Le Pro3 Guides, News, & Discussion] csyann:
rom asking for password. ok, then I will need to learn how to boot into bootloader and unlock, thanks so much!

I did not see any others have such a problem, does that mean I downloaded a wrong ROM? I'm trying to google how to boot into bootloader, sorry, I'm new to these words, any instrctions will be appreciated.
[LeEco Le Pro3 Guides, News, & Discussion] dr4stic:
US users: Do not flash the chinese rom!!!

I am gonna have a zip for you very soon... and for me, it works.... I think... lemme test some things. But for now unlock is persistent. Let me make sure it'll boot the recovery if I flash twrp permanently.
[LeEco Le Pro3 Guides, News, & Discussion] csyann:
thanks, hope get instrctions to get through. now my phone stopped at the password screen.

[MENTION=4779041]csyann[/MENTION]

Probably you need to remove Data partition from TWRP because in x727 it's crypted and then flash the stock ROM.

Here you find some information on how to install TWRP :

https://giveawaytricks.in/root-install-twrp-recovery-leeco-le-pro-3/
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
Reboot into bootloader by pressing & holding power button & volume down button at the same time until you see a screen that has some gears & text on it.

You will need to open a command prompt window in the folder where your ADB & Fastboot files are, then plug your phone into the pc.

Type fastboot devices then enter in the command prompt window to verify your computer can see the phone. It list your device with its serial number.

If that worked, then type fastboot oem unlock-go

If successful, it should respond by saying the write was successful.

Then copy and paste the TWRP .img file into the same folder where ADB & Fastboot files are and rename it twrp.img

Then type fastboot flash recovery twrp.img

If that is successful, it should respond by saying the write was successful.

Then unplug your phone, press & hold the power button and the volume up button at the same time until you see the twrp recovery screen. Then do a factory wipe and reboot.

It's possible you had a screen lock password set up before you flashed the Chinese Rom, which would cause android to ask for your password. Factory wipe should take care of that.

After wiping, reboot & you should be good to go.
[LeEco Le Pro3 Guides, News, & Discussion] dr4stic:
Do you mean you are running the chinese version of TWRP? If you downloaded the 1.8 GB chinese ROM listed elsewhere in this thread, renamed it to update.zip and then told the updater on your phone to do a system update with the local file... then you updated to the chinese rom and your device is now unlocked, but you no longer have the US features (bands, etc). I can't help you recover from this. You're screwed (for now).

If you downloaded the Chinese TWRP, followed some procedures that involved a fastboot command like "oem unlock-go" and "fastboot boot recovery_twrp.img" ... then you are just booted into the Chinese TWRP. You'll live. Find help and find my thread and follow it.

Sorry for disturbing u again, stupid questions, I tried a couple of drivers for LePro3, but my pc still not able to see the phone, which driver should I use?

for TWRP Image, can I use the chinese one, as dr4stic just mentioned?

thanks!

It might be better for everyone if you start your own thread in the Questions & Answers help subforum. That way you can keep all of the discussion regarding learning to do this in one thread, and if anyone else needs similar help, they'll find all the discussion in one place.
[LeEco Le Pro3 Guides, News, & Discussion] csyann:
Thanks, but I'm worrying about what if the developer tools and USB debugging not enabled in the Chinese ROM? in that case, even if my pc has the right driver, still not abe to see the phone?
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
Check out the surrounding towers. It was nothing but band 4 yesterday.

Thank you again, very much:good::D

Excellent work!!

Plus a shot where it actually connected inside my work building :D
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
I'm running the Chinese ROM and those tools all work fine. In bootloader, my fastboot mode works, when the phone is booted normally, ADB works (but only with USB debugging enabled).

The only part the doesn't work for me on Win10 is MTP mode while I'm in TWRP recovery. However, MTP mode works fine in my Ubuntu Virtual Machine.

So...if you're able to get the phone into bootloader, with the correct drivers installed on you PC you shouldn't have any problems accessing your phone.

Try Universal Naked Drivers and see if those work for you.
[LeEco Le Pro3 Guides, News, & Discussion] seffmono:
once connected to your computer, go straight to device manager and install the drivers from there.

I am running the GrossoShop version of the Chinese Rom. Details of the radio fix will come a bit later.
[LeEco Le Pro3 Guides, News, & Discussion] FunnyLife:
Is it worth keeping this phone?

- Bluetooth goes out constantly. Doesn't pair with my car half the time. I've had to restart the phone to get it working a few times.

- The multitasking is glitchy.

- Notifications sometimes don't come through even with changing the settings (this is a really big deal for me)

- Camera is average at best. A step down from my Moto X Pure.

- Ram usage is bad

- Chromecast(1st gen) is useless

Pros-

Looks like root has come

Roms might be coming

Battery life is good. Not as good anymore with priority notifications.

Snapdragon 821 + 4gb ram

All I wanted is better battery life vs X Pure, which wasn't terrible anyway. I am not sure it's worth the $300.
[LeEco Le Pro3 Guides, News, & Discussion] ExTREmE99:
are you on the latest OTA? my pro 3 and s3 on the 19S have been flawless in terms of bluetooth. i've used it on 3 of my cars with no issues on both phones streaming music and making phone calls. i didn't use bluetooth when it was on 18S, so i can't comment on that, but the newest OTA works fine
[LeEco Le Pro3 Guides, News, & Discussion] 903tex:

Notifications - Can be solved. See a post where you dial a number: #*#*????*#*#... (can't remember the number sorry).

Chromecast - Had the same issue. Did factory reset. On initialisation, no backup from other phone, and the first app you install is google home. Configure your chromecast. Make sure you are on the same network. 5ghz is not the same network!!

I swear some people are here just to spread negativity or troll lol. All reviewers agree that screen is really good and has accurate colors, especially for lcd display.

Issue with earphones while on call

I received my LEPro3 in US last week.

Overall, I am very impressed with phone but have issue with CDLA earphones.

During calls, mic goes on mute once screen goes off. If you press power button to bring up screen, mic starts working again.

Tries both CDLA enabled/disabled, CDLA earphones/non-CDLA with converter.

Anyone else seeing similar issue?
[LeEco Le Pro3 Guides, News, & Discussion] Veidas:
Show me those "most people" who say its bad. Lol. On contrary, most people say its really good! And your point about reviewers being paid is more than ridiculous. Those guys been on the business long enough to have a reputation, they wouldnt want to waste it. And okey, 1 reviewer, 2 reviewers, but you are telling me they are ALL paid by leeco to say screen is good? Please, stop...

So probably all users here on xda who say screen is great are also paid by leeco? So far you have given zero facts, just random nonsense accusations and conspiracy theories that everyone is bribed by leeco. This is actually getting hilarious

---------- Post added at 11:03 PM ---------- Previous post was at 10:58 PM ----------

No, its just those "small" unknown brands, if somebody like leeco did it, it would not only mean their business is over in usa, but also too big of an impact worldwide for sure. Considering they are heavily investing in US, buying land for $2billion and building huge ass headquarters, i would say posibility is around zero percent.
[LeEco Le Pro3 Guides, News, & Discussion] 903tex:
Lol when have I said anything about XDA? But look if your so happy with your Chinese phone that will most likely have no support, locked bootloader, hardly any Roms or any at all, buggy user experience, and problems with the phone before the third month then fine be happy! If I think(and have read others) that the screen isn't on par for what it suppose to be THATS MY AND THOSE OPINIONS! But to calling me a troll is childish and nonsense! But they are just another oneplus, and issues and getting help with CS will be hardly impossible, and forget a warranty replacement!
[LeEco Le Pro3 Guides, News, & Discussion] meangreenie:
+1 for the screen being alright, also 1st gen Chromecast is working fine for me too.

Notifications were a big problem until that *#*# number fix, but we shouldn't have to do that, leeco need to pull their finger out on that one.

Battery life and performance are absolutely fantastic for me.

Leeco have a real winner if they polish the OS, can't recommend it to others though atm with the notification debacle. I wonder if the ceo even knows of the situation with the software problems. Maybe a few emails, to let him know his software engineers are severely hampering his business, should be sent.
[LeEco Le Pro3 Guides, News, & Discussion] Veidas:
Back to my first point now. Its obvious you are here to spread negativity, as you just did in last post, jumping from just bad screen(and not showing other users that you speak of who say its bad) to just trying to trash the phone. Obvious hater or troll. And i have huge expirience in android, had many flagship devices, my most recent one being nexus 6p, and yes, this one is every bit as good, especially considering price. Ofcourse for 300$ it wont be best in every category available, but the overall package is more than impressive
[LeEco Le Pro3 Guides, News, & Discussion] HewettBR:
It's always a risk with Chinese companies. But if you are paying 299 for a flagship like phone the risk is small. Worst case you are out 300 best case you saved 500. In my opinion the phone is great. Battery speakers audio and Bluetooth serve my needs well. Since there is a way to get persistent unlocked bootloader on the us rom I don't see the issue. The screen is above average for an LCD 1080 in my opinion.
[LeEco Le Pro3 Guides, News, & Discussion] 903tex:
I'm done I'm no troll but if you don't like my opinion so be it
[LeEco Le Pro3 Guides, News, & Discussion] Veidas:
Its not about whether i like it or not. You speak of other users who say its bad, i ask you to show me. I can show you a ****load of known reviewers saying its a good screen, you say they are all bribed. I show you all users here having a device and praising screen, you ignore them, and keep talking about you and "other users" saying its bad. You get my point? You talk as if you are right, but you are yet to give 1 valid point or fact. Can you blame me for thinking you're just a hater? Because what i described above is pretty much what hater or troll would do.
[LeEco Le Pro3 Guides, News, & Discussion] 903tex:
Are you mental? When have I said XDA people were paid? I'm taking about those YouTuber reviewers who just like the pixel talked crap about both phones now they're saying the best phones out....
