no, i've never actually seen a phone behave like this before after a bootloader unlock. it literally resets after a reboot. what this can get us though, is root, with a locked bootloader and otherwise completely stock phone since we're never flashing twrp, just booting the image

yes, it does, i've tried everything. the password is supposed to be "default_password" but it does not work on these phones. on my oneplus 3, it matches whatever pattern, pin or password i set for my lockscreen, but that's not the case with the pro3. not sure what to tell ya about the fail message. i got a fail on 18S (came with the phone), but 19S instantly let me do a temporary bootloader unlock. sorry for potato photo, it's from my op3 haha
[LeEco Le Pro3 Guides, News, & Discussion] benjmiester:
That is quite odd. At least obtainable root is with reach though. I wonder if Leeco put in a custom password. It is pretty odd that it won't accept the usual ones. I seem to remember from the Galaxy Tab S forums that there was a way around that. I'll see if I can find it.
[LeEco Le Pro3 Guides, News, & Discussion] ExTREmE99:
the way around it should be to format the data partition that's encrypted and boot back into twrp from fastboot before the OS has a chance to re-encrypt it!
[LeEco Le Pro3 Guides, News, & Discussion] ericerk:
In theory there's an OP3 port of CM13 or something if you're able to format and / or Miui V8 if that helps, no clue if it'll actually work.
[LeEco Le Pro3 Guides, News, & Discussion] benjmiester:
Ah, got ya. All I could find is that most people used other versions of TWRP and it either worked or didn't ask. Maybe Ericerk's suggestion to flash MIUI V8 would be a good move. CM from another phone sounds pretty risky to me, but maybe that too. Man I wish I didn't have to use my phone for work, I'd be happy to try it but I can't. Then again, just doing it without worrying about failure got me into root and roms in the first place... :fingers-crossed:
[LeEco Le Pro3 Guides, News, & Discussion] ericerk:
I'd try it, but I'm really not sure if I'm going to keep this phone anymore.
[LeEco Le Pro3 Guides, News, & Discussion] benjmiester:
I hear that. Guess I might have to just take the plunge and try. I like it as is and want to keep it. Nothing else I really want more ATM within my budget. Miui would be ok too if that's what I'm stuck with afterwards lol. But I don't want to brick it.
[LeEco Le Pro3 Guides, News, & Discussion] ericerk:
Honestly I was going to keep it, but after seeing their support I've lost all hope, today was a better day in those terms, but... we need to have the device to have a proper maintainer and official CM builds.

Oh... and a PERMA-unlock
[LeEco Le Pro3 Guides, News, & Discussion] benjmiester:
I should've asked before, but do you mean just the data partition for apps/user info? If all that means is a potential factory reset, that's not that bad. I just don't want to risk wiping the whole OS/internal storage and not being able to boot anything if twrp fails to flash miui, or whatever else.
[LeEco Le Pro3 Guides, News, & Discussion] Linux23:
Sorry but what is miui?
[LeEco Le Pro3 Guides, News, & Discussion] benjmiester:
It's a rom created by Xiaomi a few years back and that comes stock on their phones. It's pretty similar to our Eui, or rather Eui is similar to it. It's got a cool full theme support system, and always got really good battery standby time and battery life in general. Also something that Eui does well on.
[LeEco Le Pro3 Guides, News, & Discussion] Linux23:
oh ok, thanks man.:)
[LeEco Le Pro3 Guides, News, & Discussion] meuhmeuh51:
Hello everyone.

I do not know if this can help, but on my lemax 2 x822 which was delivered with the Indian rom which it was meant to encrypt, I had indeed to remove the cache, data, data and system to be able to reinstall another rom ( Miui or other rom stock CN) from twrp.

Just reconnect it to mtp and drag the rom into storage.

Ps: I am on mac ox, then on pc I do not know if it is the same procedure mtp.

good luck
[LeEco Le Pro3 Guides, News, & Discussion] voidcomp:
I believe the same behavior was seen with the original ZTE Zmax. They DID end up getting permanent root after a lengthy process I think.
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
I think at this point it would be good just to see if twrp can be installed. Without a factory rom to fall back on, the phone would be useless if any other rom installed didn't work.

I believe the biggest issues with the other rom ports would be kernel & sensor compatibility. I'd hate to see somebody try to flash a MIUI rom, find it doesn't boot & then be stuck until a factory rom or working custom rom is available. It would be nice if twrp worked just for backup purposes, but OTA updates would likely be broken after that.

I suppose it's possible that X720 roms might work but I don't know if the same sensor hardware us used.
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
I'm tempted to try this. I have a OP3 that I can use if this goes bad. I'll think about it for a bit and if I have the guts i'll report back.
[LeEco Le Pro3 Guides, News, & Discussion] suhridkhan:
That's exactly my thought was too. We don't have anything to fall back on, in case anything goes south. LeEco already mentioned that there won't be any warranty if the bootloader is unlocked.

One big issue with MiUI or the Chinese ROM is that you would lose USA specific features like VOLTE and WiFi calling.
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
I just ordered a Xiaomi Redmi Note 3 Peo International version from Gearbesr last night as a backup & it should show up next week.

I wish I knew what the difference was between our phones that do unlock & don't unlock. I think I'll factory reset & try to unlock bootloader after that.
[LeEco Le Pro3 Guides, News, & Discussion] suhridkhan:
I am not sure how much of a support we are expecting from a 320$ phone. They have a bunch of staffs active in the forum. They released an update within 10 days of product release addressing many of the customer complains and the monthly security patch. I don't think it's fair to expect a 700$ flagship support.

Xiaomi Redmi Note 3 Pro International version

This thing sucked for me here in Florida with Tmobile. Slow network speed with occasional call drop. Just sold mine last week.
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
Maybe if we all scream loud enough at Le Eco we can at least get a full factory rom download. At least we could get the NON-HLOS.bin from that to get the modem working if a X720 rom were flashed.

I'm considering trying the Xiaomi flash tool if I can find a bootloader flashable rom for the x720 version and try that in EDL mode. My pc recognizes my Le Eco in that mode.

Maybe there's a way to get the OTA patch file for NON-HLOS.bin from our update to save in non-patch format?

Edit: By the way, using the Xiaomi flash tool with phone in EDL (emergency download) on Xiaomi allows twrp to be installed with locked bootloader) using this method: https://m.reddit.com/r/Xiaomi/comme...lash_twrp_and_subsequently_cm13/?compact=true

Interesting...the one I had worked great on T-Mobile here in So Cal. I just gave it to my brother up in Portland last weekend. There's a TON of developer support for that phone, including Xiaomi themselves. I hope my new one works as good as my other one did.
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
OK. Flashed TWRP it booted ok. Went through the setup, reenabled ADB debugging did an "adb reboot recovery" and I get a black screen. Hold down power button for 15 seconds, say a little prayer, and it boots normally. I would say that flashing this recovery does not work? Anyone want to grab a stock recovery for me?

---------- Post added at 03:47 PM ---------- Previous post was at 03:35 PM ----------

OK, now I've done something that keeps it from booting at all. I tried going into recovery by Power/Volume up and now it's dead. Doesn't react at all. Suggestions?

---------- Post added at 03:52 PM ---------- Previous post was at 03:47 PM ----------

OK.. Holding the power button for about 30 seconds with SUB plugged in enabled it to reboot. I guess I was stuck in the broken recovery. So yeah, don't flash this recovery :)
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
Glad you got it running again. Which twrp file did you use? I briefly browsed through this thread and didn't see reference to it, so I apologize for not being very thorough. is it the same as this twrp? https://www.androidfilehost.com/?fid=529152257862668751

Good luck getting your phone in a week from Gearbest. I have ordered a lot of stuff from there and it takes a minimum of a full month for it to arrive at my house in USA.
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
Yes I flashed the TWRP at https://www.androidfilehost.com/?fid=529152257862668751 . It works ok booting to it in fastboot but doesn't boot when flashed. I'm and idiot and didn't grab a copy of the stock recovery prior to flashing. Could someone grab a copy of the stock recovery for me.
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
I've had really good luck the past couple of phones I got from them. They have incredibly cheap DHL express shipping. I ordered a Xiaomi Mi Max for my neighbor two weeks ago and it arrived 5 days after it shipped. The key is the DHL express shipping :good:

The one in your link boots fine using fastboot. I'll flash it and see what happens.

---------- Post added at 04:35 PM ---------- Previous post was at 04:32 PM ----------

OK, I get the same black screen after flashing this 720 recovery. I wonder if the boot loader is refusing to boot the recovery due to it re-locking itself.
[LeEco Le Pro3 Guides, News, & Discussion] losteagle:
In my Zip there is a stock.img that's the original Stock recovery of an x720 if you want try to restore.
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
That stock recovery does boot after flashing. It's all in Chinese but it boots :)
[LeEco Le Pro3 Guides, News, & Discussion] losteagle:
Interesting ... your phone accept stock recovery of x720 but not TWRP for x720.
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
I wonder if it's due to the bootloader re-locking it's self on reboot. Maybe this 720 bootloader is signed and the TWRP isn't or something like that? Who knows.

---------- Post added at 05:25 PM ---------- Previous post was at 05:12 PM ----------

The OEM unlock setting is happening at boot time. I can do the following:

- boot into fastboot by holding down the power/vol down key.

- run "fastboot oem unlock-go"

- run "fastboot oem device-info" and see "Device unlocked: true"

- boot into fastboot by holding down the power/vol down key.

- run "fastboot oem device-info" and see "Device unlocked: false"

So the persistence of the unlock get's reset by the bootloader. I'm not sure how you change this without messing with the bootloader?

[LeEco Le Pro3 Guides, News, & Discussion] ExTREmE99:
again, i don't recommend actually flashing twrp, just booting into it, and rooting it for now. the stock recovery is chinese on these USA models anyway, but if [MENTION=1119693]zoid_99[/MENTION] says the stock recovery can be flashed safely from the chinese version, then that's good news!
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
It looks like I'm now bricked until I can get a recovery image. I played around and some how it no longer boots and is no longer unlocked.

fastboot oem unlock-go

...

FAILED (remote: oem unlock is not allowed)

finished. total time: 0.001s

It does boot into the Chinese recovery as well but those are my only 2 options. The only english in the recovery is update.zip. Oh well...
[LeEco Le Pro3 Guides, News, & Discussion] ExTREmE99:
ouch. how'd you manage that?! this is why i recommended people to not actually flash, but see if we can get past the decrypt screen in twrp after wiping the encrypted data partition. if thats possible, you can flash root and still have a stock recovery, and locked bootloader. also, if we have root, we should be able to port twrp and download an image to get you unbricked
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
It happened when I tried to flash root. The reboot hung so I rebooted back into recovery and attempted to restore a backup. After that I was hosed.
[LeEco Le Pro3 Guides, News, & Discussion] ExTREmE99:
so you unlocked, booted into twrp, wiped data, booted back into twrp and didn't have the decryption show? i actually think if we can boot into twrp, we should be able to use the terminal within twrp to list and download partitions
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
Correct. No need to decrypt if you wipe data.
[LeEco Le Pro3 Guides, News, & Discussion] shah_vm:

[LeEco Le Pro3 Guides, News, & Discussion] ExTREmE99:
it's already confirmed that it works, but [MENTION=1119693]zoid_99[/MENTION] couldnt get root to work even with a temp unlock. not sure exactly
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
It's probably bricked forever. I don't know of a way to put an update.zip file (if I had one) on the internal sdcard so that the recovery could use it. Since the bootloader is not unlockable I don't think there is anything I can do with fastboot. With the way the bootloader re-locks itself it's kind of dangerous to mess with this phone.
[LeEco Le Pro3 Guides, News, & Discussion] Saikou0taku:
Maybe this guy's update will do it? http://xdaforums.com/le-pro3/how-to/5-8-019s-update-t3497745

[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
It looks like I'll need and update.zip file and a USB C OTG adapter to hook to a USB flash drive. I can't see what the instructions say on my recovery as it's all in Chinese but I guess it says the same thing as in this video:

https://www.youtube.com/watch?v=zQXJUsbVvGQ

"Place update.zip in SD card or the root directory of a usb disk to update"
[LeEco Le Pro3 Guides, News, & Discussion] ExTREmE99:
i can confirm a standard usb otg cable does work with a micro-usb to usb-c adapter and usb drive. sucks dude
[LeEco Le Pro3 Guides, News, & Discussion] Veidas:
If you can boot twrp recovery even temporary, doesnt it allow to mount internal storage as usb storage? I remember doing exactly that when i accidentally wiped my whole data and had no os. Mounted, copied rom from my pc to phone, flashed and thats it
[LeEco Le Pro3 Guides, News, & Discussion] ExTREmE99:
he can't boot into twrp temporarily anymore because the bootloader relocks itself after every reboot
[LeEco Le Pro3 Guides, News, & Discussion] zoid_99:
Yes, it relocked and then the setting to allow developer setting to allow "fastboot oem unlock-go" to work was reset so I can't load anything from fastboot. Hopefully I can eventually get a stock update.zip from somewhere in the not to distant future.

[LeEco Le Pro3 Guides, News, & Discussion] benjmiester:
Probably nothing, but just throwing it out there... I came across a code from the the LG Leon forum trying to unlock and root a cheapie I bought as a backup/music player. You can go to phone and typ: *#*#759#*#* and it takes you to a menu that allows "oem mode" to be disabled. This is most likely just the same thing that oem unlocking in dev options toggles, but you never know.

Also, people have been using the Kingroot apk to root on these, apparently without unlocking the BL. Can this be done on our Le Pro3s?

[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
I just tried the dialer code, turned on OEM Mode, then booted into bootloader, but still got failed result on fastboot oem unlock-go. Evidently OEM Mode is something unrelated?

i'm on MetroPCS and am getting speeds over 100mbps, plus HD and Wifi calling that's crystal clear. This phone rocks, well except for the locked bootloader.
[LeEco Le Pro3 Guides, News, & Discussion] benjmiester:
Must be. Or just does the same thing as the option in developer options. Anybody know if Kingroot works? People are claiming it's worked.on devices that are still BL locked.... Involves just putting an apk on your phone and running it.
[LeEco Le Pro3 Guides, News, & Discussion] suhridkhan:
I have trust issues with Kingroot. It bypasses all that is about security in android.

You give it free access to your system. Who knows what this app does?

Anyone else loving the battery life on this thing? It only drops like 2 percent overnight. My Nexus 6P would have dropped over 10 percent easily.

[LeEco Le Pro3 Guides, News, & Discussion] Veidas:
If your 6p would drop over 10% over night there was some serious problem with your phone. I also have 6p and it drops 3% per 7-8h night. But yeah, this phone has 4000mah battery, smaller resolution and efficient sd821 processor, its one of the main reasons im also very interested.
[LeEco Le Pro3 Guides, News, & Discussion] sau41:
has anyone tried a different camera app for this phone? it has the same sensor as with the lg v20 and op3 but no ois, but still, it has some potential to be "okay". Was wondering if a different camera app such as the google camera would make use of its sensor's potential much better. Ordered mine and was delivered, can't use till next week though because I'm currently overseas (was not aware of multiple flash sales -.-).
[LeEco Le Pro3 Guides, News, & Discussion] HewettBR:
Yeah coming from a regular Nexus 6 here and the battery is not ecen in the same league. I got about 8.5 sot on my last charge which went about 1+ days. I've been abusing the phone.

Can we root the device now?
[LeEco Le Pro3 Guides, News, & Discussion] abel408:
I think we're closer. The latest OTA update allows the bootloader to be unlocked, but it resets the lock after a restart.
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
I bit the bullet and tried to ruin my phone. I flashed the stock Chinese X720 ROM, thinking the modem would be effed up at a minimum.

I was surprised that the phone booted and I still have LTE. Then I tried to unlock the bootloader (which I was not able to do with US ROM), and it worked! I now have TWRP v3 installed with a persistent unlocked bootloader.

The Chinese ROM has English language option as well as USA region. Unfortunately, there is no Google Playstore, so I'll need to either figure out how to set that up or try a couple other ROMs for the x720.

Here is a different link to the correct stock ROM: https://www.androidfilehost.com/?fid=529152257862681546

There is a MIUI ROM link and a Grossoshop ROM link on that forum too, so I might give those a try.

The Grossoshop ROM appears to have Google stuff installed, so that may be a good bet. I'll report back on that later.

If you want to give this a try, download the Chinese ROM and rename it update.zip, place it in the root directory then use the Update app (or in settings) to select that update, then let it do its thing.
[LeEco Le Pro3 Guides, News, & Discussion] HewettBR:
This is quite interesting. It may be a breakthrough to eventually get CM running.
[LeEco Le Pro3 Guides, News, & Discussion] ricleal:
Well done!! :good:
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
Update on my Update:

I installed the GrossoShop ROM, and it does indeed have Google Play Services and stuff, as well as root. :good:

So far the ROM is great. No Google Setup Wizard appeared during initial setup, so I'll check the build prop to see if I can add that. Otherwise, it's manually add app after app after app. Ugh :D

I did install Google Now Launcher and that works good too.

Looks like the factory Chinese ROM might be the best path (at least for now) to getting unlocked bootloader, root & twrp.
[LeEco Le Pro3 Guides, News, & Discussion] voidcomp:
There's been 2 updates since the screenshot you show. Hopefully that doesn't make a difference. Good work!
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:

[LeEco Le Pro3 Guides, News, & Discussion] wpbear:
Take the Chinese ROM, remove all files in the zip except the bootloader. Then make the update.zip run. This should install the Chinese bootloader only which should be fully unlockable. Now you have full USA ROM with unlocked bootloader
[LeEco Le Pro3 Guides, News, & Discussion] hondajohn88:
Unfortunately, the way this ROM is packed, it doesn't lend itself well to that. The .img files would need to be extracted and such :(

[LeEco Le Pro3 Guides, News, & Discussion] goalkeepr:
First, thanks for risking one for the team!

Second, I see you're on T-Mobile. One difference between the Chinese and US versions is that the Chinese version lacks band 12 support. I'm not sure if you're in a B12 area, but if the Chinese ROM supported B12 that would be fantastic!
