Guys,

Any info/pointers for me from any experts out here. As soon as I ran the unlock OEM command, it just got stuck after a message saying waiting for device. after waiting for sometime, i killed the command using ctrl+C. after that my phone stopped recognizing adb and no adb command was working hence I stopped.

Thanks,

Neeraj

it should be more than one zip file and it sould be more than some gigabytes... i dont know it by heart, but i think it were about 15 files and maybe around 4 gigabytes.
[LeEco Le Max 2 Guides, News, & Discussion] AhmadSant:
well done, great effort ,, many thanks

Yes, well done! Very good post.

:good::good:
[LeEco Le Max 2 Guides, News, & Discussion] greenManGaming:
thanks :) thats nice to hear.

just yesterday i tried the 15 second installer and i can confirm now that it works and makes the step 2.-4. obsolete

maybe step 4.6 might still be relevant, dont know yet

Dear friends.

First of all. Thanks for the tutorial. Really helpful.

I am from Brazil and I do not have total fluency in English. So apologize about my grammar.

I have some issues and need some help. I did the steps describe in the tutorial. I installed twrp. But when I try to do the sideload cmd returns a message. `cannot read the file` doesn't matter the name. With or without adm permitions was The same thing.

So I tried the pull way. This time worked.

When finally I have the Indian Running I tried to see again twrp and then. Twrp ask for password to mount decrypt data. Again. I tried to format and nothing change.

It's normal? I could use in this way.

Now I formated and restore x829 rom by otg USB drive

Thanks

Happy Easter.
[LeEco Le Max 2 Guides, News, & Discussion] greenManGaming:
im not sure if thats a problem at all. i remember i had that too, as far as i remember i just reset the system meaning deleteing chache & dalvik + data i think....

but if it works it works :D
[LeEco Le Max 2 Guides, News, & Discussion] ultratt:
I also have the cannot read file error on the sideload step. Then I just install the stock rom from TWRP, not through adb and didn't format the drive. Should I try do it in sideload mode again?
[LeEco Le Max 2 Guides, News, & Discussion] greenManGaming:
there is no need to install it twice the sideload installation is just an alternative
[LeEco Le Max 2 Guides, News, & Discussion] dbotte:

Hi, when I read the instructions I found it very complicated but when I have asked other people they said it is easy, so I think the way the instructions is written make is complicated, too much extra information, and when for example I watched video for how to setup the ADB, it was very easy, therefore, would somebody please summarise for me the instructions, you don't have to give a details but for example you say:

1. setup ADB and Fastboot.

2. ???

3. ???

And when exactly I need to connect the phone? and when to start flashing it.

Thanks,
[LeEco Le Max 2 Guides, News, & Discussion] greenManGaming:
thats a nice idea, but since my goal was to make a guide that covers almost everything if possible it got so detailed... so ill leave it up to you guys to make a short guide or maybe a video ;)

Not that I don't appreciate your great work, but when I read the instrucitons I get to the points that I am lost, for example would you please answer the following questions:

1. If I am using the 15 second ADB installer do I still need to use the Android IDE? If no, then which steps I should ignore?

2. Would you please specify in your steps which to be done in the PC and which in the Phone?

3. Every time you run the command (console), would you please confirm from where you are run it? I mean while you are in the PC desktop or in a specific folder which will give you a path.

4. What do you mean by ( 2.5 when using 15 seconds ADB installer step 2.-4. become obsolete)? Do yo u mean that if I am using the 15 second ADB installer, then I can ignore the steps from 2 to 4? ( I know it might looks like first question).

Thanks for now and I might have more questions later,
[LeEco Le Max 2 Guides, News, & Discussion] greystoke24:
Thanks a lot for this great step-by-step guide, thats what we need nowadays when everybody is out of time.

To bad it didnt work on my win 8.1 , must have something installed that prohibits adb...

When running "adb usb" it says : adb server is out of date . Killing ....

And "adb devices" doesnt list anything...
[LeEco Le Max 2 Guides, News, & Discussion] mishtag:
I can't believe that I couldn't pass the first easy step, I spent one hour to make a 15 second adb installer work, but it didn't, after typing adb devices, it returned no devices listed, so I went to device manager to install the drivers and I found adb with yellow sign, so I tried to update the driver but couldn't find the driver in the list, then I searched for adb driver online and I installed it, but then there was no list to choose the correct driver from, my pc os is win7 and I downloaded adb 1.3 thinking it is the stable one, so I will try 1.4
[LeEco Le Max 2 Guides, News, & Discussion] greystoke24:
more or less same as me, think there is conflict with other similar android device drivers, because I have also samsung and HTC phones.

That appearantly avoids "google drivers" from appearing as they should
[LeEco Le Max 2 Guides, News, & Discussion] greenManGaming:
as i see there are others interested in a "simplyfied" guide, would you mind copying mine and simplifying it in a comment? i will then link it on the very first post or copy it if you would like to :)

1. right either 15sec installer OR IDE. since 15 second installer is way easier i put the other steps you need to do the more complicated way in the HIDE section

2. which step is unclear? just wite the numbers

3. if you use 15 second installer you can run the adb command from everywhere you'll only have to specify your directory of the data you are using (in windows you can use "cd" to change the path in the console)

4. see question 1

i hope everything became a little clearer?
[LeEco Le Max 2 Guides, News, & Discussion] mishtag:
I finally was able to do it, although there is still one question left to be answer, and here is the full story (it might also help other people with driver problem):

1. I found the driver online, download it and then save in a folder.

2. Open device manger and update the phone driver by choosing the driver from the folder that it is saved in.

3. I skipped 2 to 5 steps and went directly to step 5.

4. Followed all your steps successfully until saving a backup file.

5. Finally to flash the stock rom (the Indian) I wasn't sure if I need to enter the sideload mode from the cmd commend or from the twrp in the phone, so first I tried a command but it didn't work, then I tried it from the phone and it was taking too long that made me thinking that I was doing something wrong, so I cancelled it and decide to go with your other advise and copy the rom in my phone and flash it from twrp in the phone, so after the process finished I got a message like no OS installed, I first was scared that I did something wrong ,but when then I checked the phone info I found it is now x821 (was x829) and the SW is 19s (was 16s).

So the big question, does that mean everything went well and I should ignore the message about no OS installed and I have to redo any process?

Thanks,
[LeEco Le Max 2 Guides, News, & Discussion] emmanuelin14:
is that a yes or a no?

im asking because i've seen there is some variations with the phone so i want to make sure there will be no issues
[LeEco Le Max 2 Guides, News, & Discussion] greenManGaming:
if there is no os installed that means you wont be able do boot up andorid, since it is not installed. but with my experience, as long as you can boot into adb or better twrp you can easily install a rom :)

just copy the rom you want to install on your device and install it via twrp (via the twrp button)

as far as i know the versions of the le max 2 are all compatible with all roms, although flahsing a x821 rom on a x829 device might change the shown device number to x821
[LeEco Le Max 2 Guides, News, & Discussion] mishtag:
you asked me before what is not clear from your instructions, and here is an example, you say (just copy the rom you want to install on your device and install it via twrp (via the twrp button)), do you mean from the app in the phone or through the cmd from the pc?

BTW, does that process (updating the ROM with your instructions) rooting the phone?
[LeEco Le Max 2 Guides, News, & Discussion] greenManGaming:
twrp is a ustom recovery you need to install on your le max 2 in order to install custom roms.

to install twrp on your phone you need to do that in fastboot mode via cmd (on your computer)

after you've installed twrp on your phone normally you dont need the computer anymore. (when i say to do something IN twrp it means on the phone (NOT on the computer))

rooting isnt included in this process, BUT many custom roms are rooted already

i hope that helped!
[LeEco Le Max 2 Guides, News, & Discussion] mishtag:
I meant, if I have to run twrp from the PC or from the phone (apk), however, as I stated before, looks like the ROM was installed in the phone but the message about the OS not installed made me worried, so since I have the update feature within the phone (wasn't available in x829), I re-update the phone with the same ROM and it was completed with not issues, so I now have peace of mind and will start to setup my phone, and here is the steps that I used to update the ROM (from the Leeco website):

1. Download the update package to your PC, and rename as “update”.

2. Connect your phone to PC via USB type C

My Computer > Click Le Max 2 > Internal storage

3. Drag and drop the update.zip file to the root directory of the phone.

4. Safely eject device from your PC

5. Start System Update > Settings > Local update > Continue
[LeEco Le Max 2 Guides, News, & Discussion] greenManGaming:
if you followed the steps provided by leeco it looks like you havent used twrp!

but that way too you should have a fully working andorid on your phone now :) in future you can use the update function of eui instead of updateing it manually ;)

so if you followed the steps of leeco everything should be fine and no reason to worry!

hello,,

I have Indian Rom 19s, can I flash Chinese Rom 23s? and for example back to Indian later on ??
[LeEco Le Max 2 Guides, News, & Discussion] greenManGaming:
sure, why not??
[LeEco Le Max 2 Guides, News, & Discussion] mishtag:
Just to clarify that I had x829, and I wasn't able to follow leeco steps at the beginning because the update feature was disable in x829, then thanks to your instruction, I was able to change my phone to x821 and then use the leeco steps, moreover, the update feature is enabled now for future need as you said.:good:
[LeEco Le Max 2 Guides, News, & Discussion] greenManGaming:
i think it isnt leecos fault (also the x829 version should be upgradable) but almost all reseller flash some custom firmware, that sometimes even includes malware and worse, so in any case i suggest flashing the phone after you received it from a chinese shop.
[LeEco Le Max 2 Guides, News, & Discussion] Moon75:
Hi, It was frustrated the computer Windows 10/Windows 7 did not find device under X829 Fastboot mode to install TWRP. Below is solution it might be helpful for anyone who have new Le Max 2 X829.

Le Max 2 X829, Fastboot/Adb driver for install TWRP via fastboot. You need to reboot phone to fastboot mode and update driver for Android device on the computer under device manager by select have disk and point it to unzip driver folder. Then command "fastboot devices" will found the phone and you can flash TWRP img to install recovery.

Link for driver Google drive:

https://drive.google.com/drive/folders/0B0KlgEp0nNIPQ0VPd3FVYi1UMjA?usp=sharing

- Note it's working for Windows 10

- I did not test with Windows 7/8

- I got the driver from other XDA tread
[LeEco Le Max 2 Guides, News, & Discussion] tkaczsnow:
I'd like to thanks to [MENTION=7237607]greenManGaming[/MENTION] for this excelent guide! With its help i was able to make everything i've wanted with my new x829 without any problems. I want to share with everyone with my expirience - mayby someone will find it usefull.

So a little background of my systems:

1. I am running PC with Windows x64 10

2. ADB and Factboot - from sevral months i'm using Minimal ADB and Fastboot for any android device that i have (about 8 diffrent devices)

3. Drivers - PdaNet+ for Android - working flawlessly with any device

So as you see i'm not using adb and drivers from this guide.

My the steps from the begining:

1. Boot new phone without setup acounts etc.

2. Enable Developer options and USB debugging

3. Plug the phone into PC using cable that came with it.

4. Let the drivers to install, so the phone is visible in system

5. Using adb commands boot to fastboot. (my x829 had unlocked bootloader out of box, but better check this - this guide has this procedure discribed)

6. From Fastboot run TWRP without flashing it

7. Backup using TWRP every partition of the phone

8. When backup ends reboot using Factboot commands into system

9. Copy TWRP backup folder into PC drive (you will have factory image if something ever will go wrong)

10. Copy all zips that you want to install into phone memory( i'm using Small Eui based on official chinise 23s firmware)

10. Boot into Fastboot and flash TWRP into phone

11. From TWRP wipe Dalvik/Cache and Data (optional)

12. Install/flash SmallEui V12 by Auriel

13. Install/flash SuperSU and Xposed provided in Auriel's thread

14. Boot into system, setup accounts etc.

15. Install SuperSu from the Play Store ( Auriel's was giving SU privilages without prompt - i'am not okay with that); let it uninstall privious app

16. Boot into TWRP again using any of Quick Reboot programs from the Store

17. Install/flash Path for V12 Small EUI

18. Reboot into system and start using the phone

With this setup i don't have any problems - everything works - notifications, finger print,QC 3.0, xposed, supersu etc.. Battery is great but you must now that Small EUI is designed for max battery time so the performance is capped (about 110K in Antutu). I am not a gamer, so i don't need max performance, more important is stability and normal usage.

Sorry for my english;)

Does anyone have a direct link for the the stock indian eUI 5.8.0.19s rom?

I followed the link to http://forum.le.com/in/eui_list.html, which requires registration to download, but the registration website doesn't work with chrome/iexplorer, and in edge i can't seem to get the verification code... it's horrible.

maybe it's stupid question.... but for safe I must ask

It works on standard ADB drivers, so can I do unlock and flash recovery from linux desktop ? adb and fastboot are available in debian, and adb devices and fastboot devices shows attached lemax2...

Its any risk on that solution ?
[LeEco Le Max 2 Guides, News, & Discussion] greenManGaming:
i used the driver from the 15 seconds installer, so i suppose its the standard one.

without knowing it, i suppose its safe to do so.

I had problem with installing Chinese / Indian stockrom on my X829.

After much reading on XDA and good support from AhmadSant and some other, my nose whas pointed into the good direction...

The most problem was getting a good USB driver, which I finally find!

I started a topic ( https://xdaforums.com/le-max-2/help/plz-help-unskilled-x829-user-to-update-t3609639 ), and there you can maybe find a solution for your problem.

I'd just like to thank the original poster for this thread. There's a lot of knowledge assumed in the instructions of these roms. This is a wonderful phone but the X829, as shipped, is begging for a ROM.

I think that your guide is comprehensive and has everything that is needed for "no stress" flashing custom. (even for noobie) If it's not sticky - it definitly should be. People wander through this forum searching for answers that already are answered (mainly in your thread).

There are bunch of great stock based/custom roms in development for our phone and i think it is awsome! I'm still sticking to SmallEUI - this rom serves me very well (version 14.1 rigt now)

So everybody: backup stock (beter to be safe than sorry) and flash something in your flavor;).

in general you can get help in the tlegram group for this rom. but i think you should first install the firmware if you want tu update it and there is no need to install the stock launcher

Heyyo, sorry for late reply but have you resolved this yet?

I found on my pc it failed to adb sideload ... BUT adb push works fine.

Example

adb push *name of file and .zip* ./sdcard

To fix MTP driver if you want to try that way in TWRP just go to device manager > right click the unknown MTP device > select driver > pick driver from a list > all devices > MTP device > standard MTP driver

Oh I think I forgot to mention but [MENTION=7237607]greenManGaming[/MENTION] this thread is an amazing guide! Worked great for me and I recommend it anytime anyone asks how to flash custom ROMs :)

TWRP showing zero storage space

I have successfully get into TWRP recovery

but I can not back up (Showing the storage 0Mb)

What should I do? any idea?

I have done the step for more then 10 time and change the TWRP into other version as well but doesn't seem work

The developer menu showing my phone is encrypted, is it any correlation?
[LeEco Le Max 2 Guides, News, & Discussion] jman0:
If you're using and Indian rom, those come encrypted, but don't worry. When you boot into TWRP and it asks for the encryption password, just tap cancel. Most of the times, you'll get what you already saw, you won't have access to your storage, and won't be able to backup. But don't worry. Just reboot recovery again (you can do so from the reboot options inside TWRP) and try again. It will eventually work and you'll get full access to your storage. I've seen it work right away on the first attempt, after 3-5 times, and once I had to reboot recovery about 10 times before it worked, but it always works, sooner or later.

You could also remove encryption, but that can only be done after a full wipe, and I don't think you'll want to loose your data. Or you could also flash a rom which is not encrypted, such as the Chinese stock roms or any custom rom.
