IUNI U3 stock ROMs / updating / scripts / sources - Android Q&A, Help & Troubleshooting

I bought a IUNI U3 recently and found two recoveries for the device. There is only these two builds.
I bought the device to try something new and I wanted to translate the IUNI OS ROM.
Problem is: The CWM recovery is non touch and has a bug which causes backups not to work. The TWRP is version 2.8.3 and me and a friend of mine managed to get rid of an overheating bug by adding
other default governors for the recovery (setting on demand instead of performance). Still I have some trouble with this recovery, but it is the only thing I got.
If I want to flash a ROM with it I get errors.
Code:
msm.boot_update("backup");
msm.boot_update("finalize");
in the updater script gives me a
Code:
line 108 col 26: unknown function "msm.boot_update"
line 109 col 28: unknown function "msm.boot_update"
2 parse errors
using TWRP while CWM flashes the ZIP without a problem.
If I remove
Code:
ui_print("Patching firmware images...");
package_extract_file("firmware-update/tz.mbn", "/dev/block/platform/msm_sdcc.1/by-name/tz");
package_extract_file("firmware-update/sbl1.mbn", "/dev/block/platform/msm_sdcc.1/by-name/sbl1");
package_extract_file("firmware-update/rpm.mbn", "/dev/block/platform/msm_sdcc.1/by-name/rpm");
package_extract_file("firmware-update/emmc_appsboot.mbn", "/dev/block/platform/msm_sdcc.1/by-name/aboot");
msm.boot_update("backup");
msm.boot_update("finalize");
package_extract_file("firmware-update/NON-HLOS.bin", "/dev/block/platform/msm_sdcc.1/by-name/modem");
package_extract_file("firmware-update/splash.bin", "/dev/block/platform/msm_sdcc.1/by-name/splash");
unmount("/system");
from the updater script (deleting the /firmware folder in the zip of course) TWRP flashes the ZIP without a problem like CWM does.
Is there a problem within the TWRP build or is this related to the updater binary?
Or is this command being processed correctly by the stock recovery only?
I am kind of a beginner and I wondered if someone could give me some advice so I do not have to remove the radio update.
Btw: the cooks of the mentioned recoveries are russians and I got no response until now. On 4PDA ru I can not register etc etc.

Regarding IUNI U3
Hello t-ryder,
I am sorry I cannot help you with that. I have IUNI U3 for 6 months now. I am sadly using Chinese CWM :crying: and I think I tried restoring backup once and was ok. I tried TWRP once when I bought it and it failed in installing update package so I returned back to chinese CWM.
I am currently stuck at ROM BetaV2.0 20150105. When I tried to update to Beta 3.0 It got stuck at IUNI logo because of problem with Xposed. The IUNIOS use Xposed in their ROM unofficially like MIUI did and they moved forward to blow the Xposed installation in new ROMs. Some OnePlus one users spotted Xposed working for IUNIOS Beta3 custom rom and I did not know how they did it, or may be it is broken for IUNI U3 only.
Can you tell me which ROM you installed and if Xposed is working? Which GApps you use?
The only source I found for IUNI U3 was the chinses official forums. Can you tell me if you found any other sources?
Thanks

The updater-script is parsed by the update-binary (which communicates with the recovery only for UI updates), so it's hard to imagine why it would work in one recovery but not in the other.

---

Thanks for your reply.
Thought of something like that.
When I get a new build ready I am gonna try an older updater-binary.
I heard that some builds of TWRP have problems with newer updater-binaries for some devcies.

Sounds like or the updater binary has no implementation of the msm.bootupdater function or maybe you need some binary of /bin folder that has this function.
You can decompress the boot image from recovery.img and compare to the CWM boot image if there is any missing binary that has this function.

On 4PDA ru there are some devs working on stuff for the U3. I have never used Xposed on the U3. Last stable build is b3.0.5 - b3.0.6 is so buggy, I wonder why the IUNI dev team even released that crap.
I managed to flash the b3.0.5 using TWRP changing the updater script removing the device check and the radio update.
delete (in updater script for b3.0.6)
Code:
getprop("ro.product.device") == "IUNI" || abort("This package is for \"IUNI\" devices; this is a \"" + getprop("ro.product.device") + "\".");
and
Code:
# ---- radio update tasks ----
ui_print("Patching firmware images...");
package_extract_file("firmware-update/tz.mbn", "/dev/block/platform/msm_sdcc.1/by-name/tz");
package_extract_file("firmware-update/sbl1.mbn", "/dev/block/platform/msm_sdcc.1/by-name/sbl1");
package_extract_file("firmware-update/rpm.mbn", "/dev/block/platform/msm_sdcc.1/by-name/rpm");
package_extract_file("firmware-update/emmc_appsboot.mbn", "/dev/block/platform/msm_sdcc.1/by-name/aboot");
msm.boot_update("backup");
msm.boot_update("finalize");
package_extract_file("firmware-update/NON-HLOS.bin", "/dev/block/platform/msm_sdcc.1/by-name/modem");
package_extract_file("firmware-update/splash.bin", "/dev/block/platform/msm_sdcc.1/by-name/splash");
unmount("/system");
Updating the radio once was enough (since I tried to translate the ROM and flashed the build over and over again to test).
Here is the thread on 4PDA ru - try reading using bing translator and if you want to dl something switch to original site view.
http://4pda.ru/forum/index.php?showtopic=598571
Me and my pal hellsgod edited the TWRP since there was a problem with the governors overheating the chip on performance gov.
Here the edited recovery build (originally compiled by evil goodd @ 4PDA ru)

Thanks T-ryder

Thank You T-ryder. I do not think Xposed will work for all these versions (they all have the same modified app_process) and I need it for many apps. By the way, there is a new version of firmware and it is only available in Chinese forums. its release date is 20150514 and it is recomended from the posts on the IUNI forums. The download link:
http://pan.baidu.com/s/1sj2txz3
pass: hsf2
Also 4PDA.ru looks interesting, I am already registered but I could not login because of the Russian handwriting capatcha
I need to upgrade the baseband of course, but I need Xposed as well so I am stuck. The strange thing that I saw OPO IUNI v3 ROM with Xposed installed and probably working!!

Thanks. Did'nt know about the newer release. I just looove downloading from baidu...
atm I am using a MIUI v6 port by ry09iu modified by me (I call it MIUNI).

---

This is getting more and more OT, sry.
I tried to download the 20150514 ROM maybe like 10 times now. No succes. F*** baidu.
Could you mirror it for me? I want to have a look at the updater binary and the updater script (and maybe try the ROM itself).
btw...
I even got a crowdin repo for the german translation... but translating the whole OS is such a pain in the a**.

---

Just downloaded it

Here What I did, of course with the help of google translate:
1. Create A QQ acount from imqq.com
2. Use your QQ account to login Baidu and choose to transfere the files you want to download to your Baidu Cloud (using the right arrow sign ==>)
Note: In Egypt pan.baidu.com links are not opening even with proxies (give 404 error) with some of ISPs so I had to view these links with a different ISP!
3. Use Baidu Program to download the files (It works from any ISP) the program name is: BaiduYun
BaiduYunGuanjia_5.2.7.exe you can google it. you need to login with the same QQ account and it will show the files on your Baidu cloud and you can choose to download any of them (download sign in chinese is like a capital T with a small slash \ at its leg )
Hope this helps

Have you successfully flashed GAPPS on the latest IUNI beta rom? If so, what package did you use?

---

I'm having problems installing g-apps on iuni os as well. The phone always hang at welcome screen because settings crashes.
I'm currently using MIUI os, but prefer the iuni os.

If you are using IUNI OS v2, you need to remove SetupWizard.apk from /system/priv-app after flashing, or remove it from the GAPPS zip prior to flashing.
I had Gapps working fine on the previous (buggy?) IUNI OS v3, but after upgrading to this one, I can flash the GAPPS package fine but the apps don't appear to be installed. Weird!

Thank you for your reply.
I now have the same problem as you, after flashing GAPPS, none of the apps appear.
Am using MIUI os from the link above right now.
Let me know if you find a solution.

The IUNI V3.0 ROM I shared on Google Drive is the latest production version not beta, it is better than Beta 3.06 because WhatsApp is working and it is the latest basband/firmware.
For the problem of the insufficient disk space, I have a solution:
There is a folder in most of official ROMs that you can remove safely (/system/sdcard), it contains the promotion videos and songs for IUNI U3. They are copoied to emulated storage during rom installation so they are not needed anymore because they are already there.
Delete this folder (need Root Access and file manager like Root Explorer) then there will not be space problem again (it is 250MB). Install The latest GAPPS by TKruzze, use mini/micro/pico no problem. I used pa_gapps-modular-pico-4.4.4-20150308-signed.zip and works perfectly. Here are new download page after TKruzze closed the thread:
