From Indian 19S Stock ROM to Oreo Pixel Experience and TWRP 3.2.1-0

Hi.

I'll suggest to all that installed Oreo (Pixel Experience) and have an encrypted partition, to pay attention on my report: maybe all will have a problem to use TWRP (3.2.1-0) again after Oreo Pixel Experience if have an encrypted partition (19S encrypt the partition by default). TWRP don't get acess to the partition. "Format SD Card don't give a decryted partition". And if try that, OREO fails to boot, shows a message to restore device defaults, but it calls TWRP, and... the loop begins. Maybe all OREO ROMs have this problem with TWRP 3.2.1-0 when installed on an encrypted partition.

To remove the encryption and prevent that problem with Oreo/TWRP ("wipe data partition before first boot" -- please read below):

https://xdaforums.com/showpost.php?p=72838673&postcount=4

("Stock Indian 19S have full encryption data" - https://xdaforums.com/showpost.php?p=69227805&postcount=2)

Or maybe, try Revolution 23S ROM. Install that (many system languages and latest oficial MODEM files), and after installed, do a simple device restore on EUI, and the encrypted partition is gone.

Best regards.

The TWRP decryption problem is a known issue and work is actively underway on it.

In the course of testing, I ran into every encryption mistake possible and we were still working prior to the first official TWRP.

During those times, I used FlashFire and it worked great.

This rom is going to test for the "le_x2_na" (North America X2) software before allowing installation.

I can not say whether FlashFire will honor that requirement or not.

You can edit and remove the clause from the updater-script but do NOT zip it back together using WinZip. Please search XDA for details on a good zip method for your operating system if you want to proceed.

If you don't know how to edit the updater-script you might not want to experiment with a full rom. Learn how using something simple first so that you don't end up with a brick.

Without TWRP decryption and TWRP to save you, if you mess up a FlashFire installation you are going to be in a small world of hurt.

Proceed with extreme caution ok.

I tried a couple more time and how it worked not really sure but was able upgrade to the x829 20s rom. i have the original x829 device that i flashed twrp on it and was using india 19s for as it seemed to work the best for me. When Upgaded using the phone local update in internal storage then it rebooted and twrp finished it up patching stuf etc. It deleted twrp on my device in the end process but very happy with this new rom. The fingerprint is alot better and phone is snappier. Its funny it reminds me now of my pro 3 us version in the way it looks and runs. Thank you:good:
[LeEco Le Max 2 Guides, News, & Discussion] MikeViller:
Hi retrov or Earlymon just like to know I have the India 19s to do you mean I can take this firmware rename it to update.zip put in the phone storage and do a regular system update and it will work? thanks

can you get the phone to remain a x821 because of google stuff if it change the phone to x829 I will lose all installed app and the phone will be recognized as a new phone by google.

I update with the system update by renaming the zip file to update.zip over India 19s and everything work ok so far everything work better, need to test because on 19s I was starting to have freezing problem. EarlyMon possibly you should start a new discussion to shown other users that has 19s taht they can update to a better version.
[LeEco Le Max 2 Guides, News, & Discussion] retrov:
I was able to use the use the local update in the phone. I put the update package in the root of the internal storage and just named it update. The phone system started update and after it rebooted twrp finished patching it and it kept all my original app and system settings fingerprint etc. It took me multiple tries because twrp would not decrypt data but it finally did and not sure exactly how. My twrp also disappeared after that so when I hold volume up and power together now its the factory restore screen. Phone has been working great very happy with it.

I downloaded the flash files from this thread and I use FlashOne.

FlashOne extracts the content and then I get the error: Flash file not found. Please make sure QFIL flash file is correct.

I downloaded two of the files to try but I always get the same message. The thread in the beginning says that the images are interchangeable.

So, my first question is how to avoid data encryption form the start??!!...

And 2nd... Can I flash magisk right after flashing this rom..?. Or will it create boot loop??!!..

Will twrp be still present.. or will it be replaced by stock recovery??!!

Heyyo, data encryption is forced. Nothing you can do it about tbh.

Yes flashing Magisk after is fine.

It will flash EUI Recovery. You can always reboot to bootloader and reflash TWRP. I'd recommend the latest test version as it has data decryption fixed for Indian 19s ROM.

[LeEco Le Max 2 Guides, News, & Discussion] ThE_MarD:
Heyyo, best to use a custom build of EUI ROM for 26s and higher to prevent issues like this... Especially true if you wish to avoid the ads in 28s and 30s.

http://www.myphone.gr/forum/showthread.php?t=436023

Imo it is the best form of EUI ROM. I'm an android purist so I do like my Android as close to AOSP as possible and CBG EUI ROM is definitely the closest thing to that without going into custom ROMs and everything works just fine for the Marshmallow ROMs.
[LeEco Le Max 2 Guides, News, & Discussion] coolman7:
Thank you for reply. I started to think my problem might be WiFi hardware. Because I can't download 30 MB file from WiFi. This should not be happened at stock ROM. I just bought Le Max 2 from banggood and it came with a custom ROM (I guess it might be Indian 19S or some other version). I flashed TWRP and installed 26S stock ROM. And I can't download big files. Transfer was interrupted sometimes in every few minutes, sometime in evey 20 seconds. If this happens to everyone uses 26S stock ROM, no one can use 26S stock ROM.

I will try several more ROMs and if I can't solve this problem, I will return X820 to banggood.

[LeEco Le Max 2 Guides, News, & Discussion] AgustinH:
how do I install it? through TWRP? I have rooted device. Will it work on X829? It's risky to lost any frecquency?
[LeEco Le Max 2 Guides, News, & Discussion] Bygepp:
I have X820.

First installed official 26s (link in OP), then updated via OTA to 28s, and then to 6.0.30s, via OTA as well...

I don't think you lose any frequency, because it is official.

I suggest to do the following, to obtain full compatibility with OTA.

Backup all of your data, then enter TWRP:

- Formata data, it is important, because it's not a simple Wipe Data, it will reformat the Data partition eliminating any traces of old data;

- Wipe System, Cache, and Dalvik;

- Flash 26s, you can use an OTG pen-drive, or MTP using a PC;

- After this, boot your 26s, do the initial setup, but do not update to 28s;

- Restart to TWRP, and when asked, swype to allow modifications to system partition (I know it doesn't make any sense, but leaving the system partition in read only, will result in failing to install OTA updates);

- Now, reboot to system, and do the updates.

If you are having any issue, like "Error 7", when installing, I can provide to you some workaround to get it working.
[LeEco Le Max 2 Guides, News, & Discussion] AgustinH:
I like a clean install? Where is the format data? I have the last TWRP install (I root my device not a month ago). I can't put the file of installation on the internal storage and then install through TWRP?
[LeEco Le Max 2 Guides, News, & Discussion] Bygepp:
If you formata data, then all data on the internal storage will be deleted, so you have to copy the file through an OTG pen-drive, or via MTP, inside the TWRP itself, because you can't boot the system anymore after wiping everything.

This is very important, DON'T BOOT the system after wiping system, because it will result in brick...

Format data is in TWRP-->Wipe, before advanced wipe.
[LeEco Le Max 2 Guides, News, & Discussion] AgustinH:
mmmm ok, I don't have an OTG with usb c plug. How can I do it with MTP?
[LeEco Le Max 2 Guides, News, & Discussion] Bygepp:
Plug your phone to a PC with the cable, and it should appear as "X2", then just copy to internal memory the file, and flash it.

If not appearing, go to TWRP-->Mount, and make sure that MTP is enabled (lower right corner).
[LeEco Le Max 2 Guides, News, & Discussion] AgustinH:
the first I can do it, but how do I flash it? With adb?
[LeEco Le Max 2 Guides, News, & Discussion] Bygepp:
Just copy the file to internal memory, and then flash it via TWRP.

When connecting the phone with the cable to the PC, it should appear as a memory storage, copy the file into it, then it will be on the phone, just install it as a normal flash with TWRP.
[LeEco Le Max 2 Guides, News, & Discussion] AgustinH:
Thanks [MENTION=8209318]Bygepp[/MENTION], but again I'm confused. If I format data everything I'll put on the phone will be gone, or that thing I have to do it after format all data
[LeEco Le Max 2 Guides, News, & Discussion] Bygepp:
Yes, after.

First format data, then wipe system, cache, and dalvik.

Then go with MTP, copy file to internal memory, and flash.

Then the other steps.

[LeEco Le Max 2 Guides, News, & Discussion] Bygepp:
[MENTION=6607081]kanagawaben[/MENTION], maybe figured out what happened.

You did clean install, or dirty?

Because it seems that the problem is a missing app, GoogleContactsSyncAdapter, but if you dirty flashed, maybe the file was still present from previous installations.

In any case, I think the problem is solvable with restoring that app...

Bricked X2

Hi guys

Yesterday I managed through Qfil to recover my X2 that I bricked by having made a bad installation of a MiUI rom.

I turned on the phone and voila, it worked, but... with the screen divided into two parts, from the center to the right and from the left to the center and, only with 9.71 GB of internal storage.

The storage problem I have already solved through TWRP format and is now 115.55GB.

I was recommended to install this Rom: LE_X2_X820-CN-FN-FEXCNFN5801507014S-5.8.015S.zip, which I already have on my PC, my question is this: can I transfer it to the internal storage of the phone and install this rom via TWRP by deleting the Dalvik cache, Cache, System and Data, how we proceed with the new Roms for X2?

The TWRP recovery I have installed is 3.2.2-1 Ported, does it do the job well or do I have to install another one? ?
