Any chance to flash a custom rom to my newly purchased Le Pro3 X720 with EUI 5.9026s?

Hi all,
Recently, I go through this forum and found there are many custom roms ready for this Le Pro3 phone. After consider the hardware specification and cost, finally I procured Le Pro3 (x720) phone.
However, when I received this phone, I found the latest EUI already installed (EUI 5.9.026s). When I go through the instructions provided by XDA forum, I found there almost no way to unlock the bootloader of this phone if this came with EUI 5.9.026s.
Can someone tell me if there is a way to unlock this bootloader if this phone is came with EUI 5.9.026s? If not, can I still can refresh my phone with some custom roms (like Omni rom on lineage OS?)
Thanks

I have no trouble with my x720, first time flashed customs on 20s, but few days ago returned from stock 26s to custom. Can't you unlock your phone?

No luck on unlock.
I believe you already installed TWRP before upgrade to 26s, so you can falsh back to previous version.

Have you official ROM and followed the unlock guide?

I follow the unlock Guide but no luck. I go through few discussion in XDA forum, seems some major changes in OS permission settings on 26s rom

Maybe flash 23s, wipe then try?

I cannot try it, but maybe it's possible to fool the update system. By modifying the update script of a 23s OTA file you can bypass the check for rom and modem version, then the system will execute a "downgrade" from 26s to 23s. This theorically, I can't try if it really works but the right path can be this! Cheers!

I did downgrades from 20s to 18s and from 23s to 20s... Seems buggy, but after wipes worked perfectly.

@marik1
How did you do the downgrade? Is the way you downgraded possible with a locked bootloader? Thank you.
(I am considering buying a Le Pro 3, but I will probably wait until I know that unlocking the bootloader is possible with the new EUI installed.)

For me it's simply flashing file with ROM called "update.zip" and placed into main folder trough LeEco's recovery. Like making update, but with different file.

I tested qfil by following the thread here to flash the previous rom but no luck, when I use qfil, I am quite sure the phone is connected ( I can see the com port), the process started(rom are unzipping), but when the system try to write on the disk, the process failed. I wonder if there are any permission/encryption settings applied on the partition of 26s rom, and not sure if I can downgrade due to partition permission.
BTW, where can I download 23s rom? and how to modify the script to prevent version check? thanks

Where to download this file? and the file should place on main folder but not root folder, right?

Just flash it, without changing version checking. You can take it from LeEco website;
https://bbs.le.com/zt/eui/le_pro3.html
You can also have trouble with connect, so you have to remove :110 from link and you gain;

Can someone confirm that unlock works for new devices which are shipped with the new software version? @andylcm please let us know if you get it working. thanks

the problems have been fixed.
Actually, I follow the unlock guide here, the problems was on this bootloader unlock guide but not on the phone itself.

@andylcm
Could you please explain what you did differently from the guide?
Is this the guide you are referring to? https://forum.xda-developers.com/le-pro3/how-to/leeco-le-pro-3-root-t3476560

I know that device info command shold be device-info

Installing another EUI version to X722 and advantages of unlocked BL in this phone?

Hey guys,
I bought a X722 version of Le Pro 3 a few days ago on Banggood. I know about the disadvantages of this particular version, but I'm fine with staying on EUI (I used Small EUI by Aurel on my old Le Max 2 and I was happy with it.) But I'm wondering about the ROMs.
The phone will come with international version of EUI (I think it's modded 20s,) as it does from the other abroad shops. Here's my question. I know that this version doesn't have OTA updates. Is it worth it to put in the official ROM and then update to the last one (26s) with the locked bootloader? Because some people say that it's worth it, some say it isn't - but I didn't find any changelogs or anything that would prove me that anyone of those two groups is right.
Also various sources tell that X722 has an unlocked bootloader with the default international version of ROM. That's fine, but what are the advantages of it, talking strictly about X722? It looks like there isn't any TWRP and root available for this phone (and if it is, can someone post a link please?) so what is the advantage then? Or do I just have bad info and those are available?
Thanks

Manual from X720/X727 is applicable to X722. You can install TWRP and SuperSU

Thank you, that's awesome to know! So many topics and articles about X722 say that you can't put those on it, so I was kind of already accepting the fact that I'll just end with everything stock. So that kind of answers even my second question - there's no point in going to the version with locked BL, even though it's newer. Thanks again.

Hi,
I also had an x722. I got EUI 5.8.0.20S with the Shopping ROM from GeekBuying. Installing TWRP worked but after I tried to flash the newest official ROM the phone bricked and there was no hope because the bootloader is locked. Now I shipped it back to GeekBuying.

Thank you for the info, that's really good to know - so no ROM flashing for me, absolutely not worth the risk.

1. There is no TWRP for X722
2. There are people installing TWRP for X720
3. Almost all X722 brick happens when upgrading to 26S by TWRP
4. I would not use TWRP of X720
5. If you want to update to 26S (bootloader is blocked) updates from phone, NOT FROM TWRP OF X720.
Greetings.

Thanks a lot for the info! So the problem is in the not fully compatible TWRP, not in the ROM itself. I don't want to update to 26S anymore, but I guess TWRP from X720 is good enough for root and flashing other stuff than whole ROMs, so that's it.

i need links download all stock rom

Lg G5 H850 sucessfully changed region and firmware on stock non rooted

Hello. Great news from me ?
I sucessfully changed my ISR firmware to EU firmware. And guess what, no cust error on boot. Yeahh
Its like this:
Just download latest 20p firmware and flash it via lgup 1.14 and uppercut. First set lgup to refurbish and click start. Phone will go to download mode and start flashing. It will give known error *kdz not supporting refurbish* and stop on 4%. Do not exit from download mode on phone. Reopen uppercut and flash 20p firmware in upgrade mode and wait.
After flashing make factory reset phone and voila U have 20p firmware without cust error message
I used this firmware
H85020p_00_EEO_GB_OP_0916.kdz
Happy flashing ?

Now i have no problems with BT and my secure level is 9.2017

i recommand to update your whole cust folder with all other folders in it at first before updating to 20p!!
You should restore cust folder from 20c ( or your old version!) after backup!
And of curse edit your cust_path_mapping.cfg to your country code ( for me it was ffffffff,11 )
you will find your code entering *#546368#*850#
without this steps, i had many problems with system stability and BT!!!

No way. How to backup cust folder or edit it when our isr g5 is not rootable. We cant unlock bootloader. I'm using 20p firmware after flash from 20c and apsolutely no problems at all. Cust folder is market depending for provider apps, network settings or similar. Firmware is same for all g5 h850 and hardware also.
Cheers

@jaskooo
if you think, it is working alright, ok.....
the main thing is, that you are fully satisfied now!

Baseband / RadioModem for Z2 (plus) for twrp

Hi mates,
as I got a lot of requests for providing basebands for Z2 (plus) as well I will try adding them here.
-------------------------------
ATTENTION!
If you use encryption then dont flash any baseband as if may corrupt your encryption.
Check your current baseband version first!
Your baseband is 1.70? Great! You are on ZUI China? Happy flashing!
Your baseband is 1.76? Dont flash, you will softbrick your phone. Flash ZUI China version first.
Reason: There is a China version (baseband 1.70) and an Indian version (baseband 1.76). The provided basebands here are China versions only. Cannot be flashed on top of Indian version.
If you have ZUI Indian version installed install ZUI China first.
All flashings are on your own risk. I'm not responsible for any damage.
I don't have a Z2 (plus) so take care.
So to make it clear once and forever:
1.70 is China baseband
1.76 is India baseband
The higher version number does not say anything about it is actual newer.
ZUK decided not to change the baseband version anymore from 1.70 on. So if you want the latest baseband you have to take it out of last released ZUI.
It cannot be seen under phone info. You will always see the same number there no matter which version is installed.
Read the things above. Understand it. Don't ask me anymore to that, I'm tired of explaining always the same.
Use latest twrp official version to flash. Download it at www.twrp.me.
No wipes needed after flashing.
ZUK never changed baseband numbers but changed content anyway. Dont ask for changelog, there is none released by ZUK.

---------------------------
Notes
Offline Charging: If you run a CustomRom based on Android 8.1 that pretends to have offline charging you NEED a baseband of Oreo (ZUI 3.5.xxx) to make it work.
-------------------------------
TroubleShooting:
Problem: After reboot your phone requires your usual pin on lock screen. But even when typing correct pin it will switch back to lock screen.
Solution: Reboot to twrp.
In twrp start file explorer (find it under advanced)
In folder data/system delete all files beginning with "locksetting". Usually one to three files.
Reboot. After reboot no pin is necessary, you need to re-setup again.
Problem: I get no LTE / 4G signal anymore. HELP!
Solution: Thanks to @vickdu31 and @juyer there is the following mini guide:
- VoLTE users: Backup EFS partition with twrp.
- Download 3.5 latest baseband from this post
- flash it with twrp.
- Extract .zip of baseband
- Reboot to fastboot
fastboot -i 0x2b4c flash modem NON-HLOS.bin (this file is from .zip baseband)
fastboot -i 0x2b4c erase modemst1
fastboot -i 0x2b4c erase modemst2
fastboot -i 0x2b4c reboot
LTE working instantly.

Again: 1.70 or even the whole baseband number is not relevant. ZUK changed a lot without changing the baseband version number sadly.
If you dont habe problems you dont need to flash. If you experience radiomodem related problems flashing this may help you
By the way: if you run a custom rom based on 8.1 you need a ZUI 3.5 baseband to activate offline charging

I know there are different other sources. But they are quite fragmented. This thread here shall be an easy source to just download and flash a new radio modem / baseband version.
It would be good to get a flashable 3.5.261 version as well. I needed to start somewhere
For Z2 Pro I released all RadioModems already since long and maintaining the thread always to add newest version.
for Z2 (Plus) I need help to get all versions
to screenshot: He may have installed the 1.76 version before already and then flashed ZUI by twrp. Flashing ZUI with twrp will not change the baseband. Only flashing ZUI with Qfil will overwrite baseband.

Sorry for asking this stupid question but... What is offline charging?
