X720, X722 and X727 uses the same ROM?

[vsrocha]

hi guys, i have the X722, i can use ROMs of X727 and X720?

 

[sk8223]

No the x722 has no custom ROMs. You'll soft brick the phone if you try to load any ROMs from other variants onto it, to my knowledge.

Unfortunately, I also soft bricked my Le Eco Pro 3

I tried for 16 hours to resolve the issue and could not. However, after I did the research I now understand what I did wrong. Also, I got rid of the phone. Though I will probably order another one and be much more careful next time.

For anyone else reading this post : don't trust every comment here. Some people will give incorrect or incomplete info, such as advice to wipe the system to get around encryption.

* That's what I did and after successfully unlocking the boot-loader, I find that my system was somehow encrypted.. I did not encrypt my phone so I am not sure how this happened. In my haste, I did not create a recovery, I thought that is what the official Leeco twrp was for?

Options?
I too read about the Qfil tool, at the time I was having trouble downloading the files so I attempted to wing it... and failed.
I see now that I did not spend enough time on this complex option.

Update:
here is the exact instructions for using the Qfil method. ( this link provides step by step, and is tedious, but appears to work.

Sigh! I attempted to post a link and could not, due to being new on this site.
No doubt, I found the best instructions that I have seen yet on the Qfil Process.
Its on the unoffical Leeco Repair site : tora33 #comment-15320 this post is much more extensive than some other posts by Tora33 linked from XDA
Again, I can't post the actual link here! Just search for : unoffical Leeco Repair site : tora33 #comment-15320

Potential other options

     [*] This video seems very promising! Unfortunately, I wasn't able to find this video before now.
     Since I am new here I am not allowed to help you by posting links!
     search YouTube for How to unbrick any bricked letv phone without loosing data ( easiest way ) in Hindi.
     Yes its in Hindi, but you will still understand because he used some English and it seems that he has built a fairly useful tool. Although, its still easy to get the gist of what he is telling us and he apparently built a program to repair a bricked Leeco phones, and he has other videos
     
     [*] Finally Google : LeEco X820 Max 2 Super Unbrick Guide ( gizmochina. website) seems to be another complete solution.
     
     
   
   
   I hope this helps you!

How to unbrick any bricked letv phone without loosing data ( easiest way ) in hindi.

1. He shows us that his phone is stuck on the logo and his recovery won't boot (it should start in 5 seconds).
2. He says to go to the stuck bootloader page, press the power on/off button and volume down button continuously to get into Download(?) mode.
3. Connect your phone to your PC and use your unbrick tool of choice. The tool linked in the video description is for the LeEco Le 2 x526, NOT the x720/x722/Le Pro3 models. So I wouldn't recommend you use it unless someone here can confirm that they used it with their Le Pro3 successfully.
4. Assuming this program works with all LeEco phones (not confirmed yet), continue with the process on your Le Pro3.
5. A cmd prompt will come up after you connect your phone and start the program. The instructions are in English. Choose an option--first install adb/fastboot drivers if you haven't already, then press 3 to Unlock the Bootloader. Check the bootloader's status by pressing 4. If it says "device unlock: true", it's unlocked.
6. Flash TWRP by pressing 5. I don't know which version of TWRP this program flashes, and whether or not it's compatible with the LeEco Pro3.
7. Then press 6 to reboot your phone into TWRP. You can now remove your cable and flash your ROM (most probably stock). Your phone is unbricked.
8. If your phone lost your data, you can connect via OTG storage and transfer ROMs and firmware/zip files to your phone using OTG. Reflash eUI 5.8 because 5.9 will most probably bootloader lock and brick your device again. Remember to select "swipe to allow modification" and "allow disable".

You might want to use the tool mentioned here to unlock the bootloader if the tool used in this Youtube video doesn't work (you'll have to add your phone's files to it though): https://forum.xda-developers.com/showpost.php?p=73988576&postcount=66

Hey, good on you for figuring out what went wrong and sharing it with the rest of us!

Whatever you do, don't order a Chinese phone from like Gearbest, Geekbuying, Aliexpress, LightinTheBox, and all those other wholesale websites. They even shamelessly put their crappy vendor ROMs on Xiaomi phones. They put vendor ROMs on their phones that send data back to god-knows-which servers in China. Well, even OnePlus and LeEco do it natively, but I trust them over some shady wholesaler. If you absolutely want an LeEco, buy it through Amazon U.S. or Amazon India, Flipkart, etc. An official retailer is best.

Otherwise I recommend Motorola phones, even though I hate mine. They're generally cheap, they're stock, and they're a much safer option.

Thanks for the detailed steps, and providing the actual links, it will definitely help people.

Btw, I bought another LeEco Pro 3, from Amazon. At $199 its the best deal available for a device that has a Snapdragon 821processor, among all of its other features.

Right now, I am still using stock. Soon, I will unlock the bootloader, install TWRP, and root the phone.

I have become accustomed to the stock software and would stick with it for a while if it was running Nougat

To be honest, I am still a noob with installing custom ROMS, in case I ever decide to go back to stock, do you have a preferred method of backing up the stock software prior to installing a custom ROM?

I know that I can create a recovery within TWRP and back that up... us that sufficient enough, or is Titanium a better option?

Thanks again.

The Le Pro3 is a great phone... on an official ROM, and if it's the x727 variant. The x720 variant is good too, but much harder to find a native SafetyNet ROM for it. Stock passes SafetyNet integrity checks. It's good that you bought it from Amazon. You'll most likely be getting a native SafetyNet-passing device and a decent warranty. Even on eUI, LeEco phones are viable. Especially if you're used to iOS. What I absolutely despise, though, are shop ROMs, and now I'm stuck with one. :crying:

Backing up stock? The moment you get the phone, set it up as normal but don't add any information if you don't have to to it. Like skip the Google account setup and whatnot (if you can). Unlock the bootloader & put TWRP on it. Make a Nandroid backup of your stock unmodified firmware. Heck, even just backing up your fully-setup ROM is fine. Just make sure you erase data, cache, etc. before flashing it (and remove the other ROM you're using).

Otherwise you'll find stock factory images for your device here on XDA if you need to go back. Download them before getting your phone if you don't want to wait.

I prefer Nandroid backups, but if you want to backup apps one by one, use Titanium Backup. I don't really like doing that anymore because Nandroids are more convenient, but if there's an app you absolutely need to add to all of your ROMs, then back up the app separately.

Thank you for you very good detailed advice. Its truly appreciated.

I was decrying the shop ROM a lot but it's okay. I thought it'd be a lot worse than it is, but at least it lets me play the games I want to play on it without issue (so far...). I'm debloating it soon. Gonna remove all the LeEco apps. I hope kernel sources get released for the x722 but I ain't holding my breath.
