An advice, make Full Backup of current ROM/Firmware before doing anything with device you are willing/thinking to try.
I'm using Huawei Ascend y511. so can't do that, but i believe "CN" stands for Chinese and "EN" sure for English. regarding recovery language, for me i get two different modes, recovery and factory setting i believe. Stock recovery for my mobile is in English and the other is Chinese. But, in case you get chinese recovery, i think it can be replaced with "Custom Recovery (English)".
Once Stock/Custom ROM is installed/flashed, you sure can change language option to English or Chinese as mentioned about ROM languages (Not for recovery).
Point is that; once ROM is installed/flashed & you are satisfied with it and you also got backup of current Kitkat ROM and you find recovery is in CN. You can restore ROM to Kitkat or in case you don't care about warranty and can flash/install Custom recovery(English language) without going into CN recovery. then i think it shouldn't be a problem.

this rom work fine with my device

Android 4.4.4 on Acer A500 Working Partially
I was running ICS 4.03 and installed the 4.4.4 from this thread:
http://forum.xda-developers.com/showthread.php?t=2705989
Using Skrilax V9 bootloader and CWM 6.0.4.5.
Omnirom Kitkat loads up fine but cannot restore apps through Titanium Backup and as it reports no Root access.
Also Google Play cannot locate this device but I can log in and see my apps using the stock Browser that was installed.
Made several attempts with Google Android Manager to no avail.
I assume this custom ROM has root access correct? If true, don't understand why Titanium Backup is complaining.
Location is set for Wi-Fi and mobile network to determine location.
So for now cannot restore my apps locally via Titanium Backup until I get to the bottom of the issue.
Your guidance appreciated as well as the work to make this ROM available to such a broad audience.
DISREGARD, I am getting everything working in the light version.

Rom for Acer A500
Hello I am new to the forum and also the modding and not perlo language very well.
I tried to flash the recovery "update-recovery-thor2002ro-rev1.7.3" the "OmniROM-4.4.4-Tegraowners ROM v21" the work went well but sometimes I crash.
Can you tell me what is currently the OmniROM 4.4.4 better and more stable than those in the first page, and if I can flash with the current recovery, (update-recovery-thor2002ro-rev1.7.3), pointing to the steps to do because I lost in the discussion not knowing the language in fact I am using the translator.
thanks

I used the instructions found at the beginning of the 4.4.4 Light version thread as the full version gave me issues. I didn't use the Thor recovery, Skrilax version 9 instead.

Can I install build 8 overtop of build 6?
Can I install build 8 overtop of build 6? What I mean by that is can I install build 8 without wipeing data in CWM because I already have build 6 installed and I have the same ROM so can I?

Loss of Root
Has anyone else lost root with build 8?

flickering screen with Facebook?????
I installed v6 of omni ROM on my Acer a500, and just updated to the newest version. Both ROMs are am some and smooth, but I have just one issue when I have Facebook open for a few minutes, I go to scroll down then the screen starts to flicker and I can't do anything. And to use it again I have to reboot otherwise I just get a black screen. It happens on both versions of the ROM, anyone else have this issue???. Thanks for any replies

Hello , I am trying to flash this rom on my Acer a500 and I get this error :
This package is for "picasso.a500" device this is a "ventana".
E:error
Status (7)
Could anyone help me with this issue?

Lockups
yeah i have been having a few issues along the same lines, i think its more to do with disk 'bandwidth' usage than the cpu. With low data throughput apps running it will run for days without issue, start downloading at 500kB/s (or sometimes as little as 370kB/s) and do some other disk intensive task and pop its gone! this could be biased a bit by my experience of it as i quite often use the A500 to dl things or load it up with stuff before a journey etc.. have also had it get stuck in deep sleep modes but think thats the disk issue as well...
Could it be overfilling it disk buffers or something? not much experience with android hardware but this tablets a bit old now and new roms may be expecting the inbuilt storage to be performing a little faster than the a500's can deal with
Also have tried all the available i/o schedulers and none seem to have and noticeable difference in time between hangs, although without bothering to setup proper test conditions i cant really say much really
oops was meant to be in reply to http://forum.xda-developers.com/showpost.php?p=60787006&postcount=293 meh....

LNX partition not loading?
Hello and sorry if it's an easy question but it's my first time trying to install roms. I've followed http://forum.xda-developers.com/showthread.php?t=2705989 to install OmniRom 4.4.4 on my iconia A500. I installed Skrilax bootloader V9 and then CWM 6.0.4.5 on my device and up to now everything worked well. I then put OmniRom 4.4.4 build 8 and gapp pico on a micro sd card, wiped data using CWM then install the rom (from /storage/sdcard1) then installed the gapp (also from /storage/sdcard1), then wiped cache partition and rebooted. I've been stuck on the Skrylax "booting android image from LNX partition" for half an hour now... Where did I make a mistake?

Using TWRP-2.6.3.0 to install Omni 4.4.4
Hi all,
Just want to know if it does matter to use TWRP-2.6.3.0 (instead of 2.6.3.1) to install Omni 4.4.4...???
Anyway, the installation went through w/out any issue. I'm using my revived Acer-A500 (was bricked for almost 2 yrs).
W/out this XDA-Dev's great resource, I would not be able to revive my bricked Acer-A500 & running Omni 4.4.4 (CM-11) now.
Many thanks to everyone on the board, especially, Skrilax, blackthund3r, civato & all the great XDA-Dev team...!!!
Cheers,
JKS

Convert to ZUI 2.0

Hi,
I saw the chinese threads regarding ZUI 2.0 and it was really confusing to understand what to download, what tool to use.
The existing threads are outdated or contain the rom.
I want the details to specifically install official ZUI 2.0 with download links and the QPST tool process. I am currently running CM 13.1 with TWRP Recovery.
Thank you.

If this is a pre rooted rom, I will just have to wait for the new pre rooted version to be released before flashing right?

Hello There!
Hey Bro,
I have tried this on my ZUK Z1 earlier. (ZUI 2.0.80 ST) Via TWRP it flashed properly works fine but when i'm trying to restore my CM13 Backup it always gave me error. And i have to format the data partition as well and install CM13 all over again always i have tried 2-3 times every time everything gone. Do you have any solution. I want to use ZUI 2.0 but i come back often to CM13 as well.
Thanks in advance!

Yes you are right. OTA didn't work. I have already tried. OTA failed with no network error. Try to download 2.1.049 from Chinese forum and search how to root. Kingroot is not safe for rooting I think. I red some were. But didn't search more about it.

@nil.d
ZUI and CM both are different. So I don't think that restoring data from CM to ZUI or from ZUI to CM will work. I flashed ZUI 2.0 and tried to restore apps with Titanium Backup. But it didn't work.
For me few issues with ZUI. Can't sync Google contacts, and Titanium Backup didn't work. I am using CM13 now.

Bricked huawei g play mini (p8)

Hi guys, I tried installing LineageOS 2 days ago, and I wasn't smart enough to backup before doing so.... twrp can't install LineageOS on my device, and now I got no OS. I tried installing lots and lots of OS, including the original stock rom, but there's always some error that stops me from doing so. When trying to install the official stock ROM, using huawei's recovery, I get a cust error. TWRP also gets an error, when installing any rom, probably because it's an outdated version, but I can't get any other version to work.
Any help or is it dead?
