So here it comes. After some weeks of thorough investigation and digging around on Chinese forums (nobel prize for google translate !!! ) I managed to find solution for people having issues with their Chinese regional version of google-deprived chinese ROM,
I found it couple of days ago on one of the Chinese android forums where one of the users managed to somehow pre-root software and add google support into android.
this seems to be STOCK ROM with added play store, google maps and root. flashing rom DOES NOT INCREASE FLASH COUNTER so seems its built on an official chinese rom.
I AM NOT DEVELOPER OF THIS ROM I JUST MANAGED TO FIND IT ON ONE OF CHINESE FORUMS !!!!
i post it here as solution for people who bought their phones in China or HongKong and suffer from Chinese government's google blockade.
Rom appears to be the same as the stock ZCUAMF4 with google support and few chinese apps added which usually you wont find in Chinese regional systems (translators and dictionaries)
How to flash ?
0)Make sure your phone is i9200 (chinese version, not sure how the rom would react to other regions, in case of mine it works perfect )
1) connect in download mode
2) flash whole tar file through odin (dont worry its not signer with md5. I flashed it and the rom works flawlessly )
If somebody has any questions regarding problems after flashing feel free hittin on me by pm or here.

i have the same problem with i9200 znuami2 (just slightly newer version of the Chinese ROM i think, no google apps, lots of Chinese crapware).
does anyone a working solution for this.
the download links in this thread are dead.
I am planning to buy one of these tablets to tinker with. After some searching, I found the following rom alternatives:
http://www.arctablet.com/blog/forum...-firmware-version-1-04-test-version-20130723/
http://www.slatedroid.com/topic/91121-tempestu39gt-roms-v0001/
http://www.slatedroid.com/topic/89434-custom-firmware-from-4pda-based-on-stock-104/
Do you know of any other worthwhile rom to try out, or are these three all that's available?
Anyone?

thanks for sharing, gonna try the TempestU39GT
There's also 1.05 multiwindow rom that some say is better than stock 1.04, download is here :
rom
Do not buy the Cube U39GT-3G version of this tablet, I ordered one from http://www.cube-tablet.com and it came with a wrong IMEI number. I cannot use any SIM data card because of this with this tablet.
I bought the Wifi version, so I am not in danger. Thanks for the warning though, it certainly speaks of extremely crappy QA.
racht: anytime, and thank you for the link to 1.5.
It seems like another rom might be on the works:
http://www.freaktab.com/showthread.php?8204-Are-there-any-worthwhile-roms-for-the-Cube-U39GT
Apparently it will be based on stock 1.04 instead of 1.05, but if it comes to completion it might be worth it to try it out.

ROM has been uploaded yesterday but the dev doesn't own a U39GT. So anyone willing to test can do it now
I can't believe that slipped by me. Thanks for the heads-up. :good:
http://www.arctablet.com/blog/forum...2-custom-root-firmware-version-1-06-20131123/
This looks promising as well with 1.06 Cube firmware update and AOSP launcher.
New original Cube firmware 1.06 is downloadabl from official cube site.
http://www.51cube.com/ch/DownShow.asp?ID=205
I can recommend Google for translating the chinese, you can download the ROM from baidu which could take a few hours.
Awesome, thanks for the heads-up.
They require registration to access the downloads? Dammit, I refuse to create an account just to go and download something. Do you have an account there, locutus2000? If so, would you be willing to mirror it somewhere?
I was able to fix the IMEI issue, so it is safe to buy, again. The support from the vendor was not helpful, the wrong IMEI number is not only wrong for me but for all of the sold models. They all have 111111111111111 as IMEI number, no big deal with the MTK Droid Tools I was able to load a new IMEI, that was generated from an internet site. It works with the SIM cards now.
Important to know: the Cube 9 Talk with the 3G SIM card uses MediaTek MTK8389T CPU whereas the Cube 9 without the SIM card 3G feature uses a RockChip RK3188 CPU. The ROMs are not interchangeable.
So whatever issues you may have, it may be a completely different story for the person that owns the other chipset. Strange enough that Cube built two similar products with completely different hardware.
The Cube U39GT 3G ROM Version 1.03 for the 3G version can be found here:
http://www.51cube.com/ch/DownShow.asp?ID=206
If you have donwloaded and unpacked the firmware, you may end up with chinese folder names. Flash tool did not accept the scatter file when I tried to select it using these folder names.
To resolve this: Simply create a new folder name and copy/paste the ROM of the Cube to the new folder, the update should then work with the Flashtool. I have used Version 3.1328.0.183. The update takes a while so be patient. Worked with mine.
rooting cube u39gt
Hi Guys

Thank you for important info, I have 3G version too. And how did you succeed root, can you give me any advice?
Starting this thread to answer a very simple question.
I find some answers scattered through responses in a lot of other threads, but all the information is too spread out to be useful, so I'm trying to get all that info in a single thread.
Most of us will get their P780 through a Chinese website. Most of them will have an English interface probably, but are still the Chinese models.
The main difference is explained elsewhere, so not going into that. Just wondering, I'm living in Europe, but temporarily in Australia.
I have an Australian SIM1, and my European SIM2. Works just fine. Full reception on SIM2 all the time, SIM1 is kind of unstable, going from full reception to almost nothing and back when on 3G. But apart from that, fast data transfer.
In most countries, 3G on 900Mhz is not that popular anyways.
So, is there any reason to flash an ROW rom to a Chinese phone ?
- 3G 900Mhz band not available on Chinese models : does the ROW change that ? Or can you change it by flashing a different modem image or can't you enable 3G 900Mhz at all on them?
- custom ROM support : but so far I haven't seen a ROM interesting enough to do this. Most of us will want the latest android version, which is only VIBE 1.5 on Chinese ones anyways at this moment. SLX and Life look ok, but I don't see much difference with the VIBE roms (UI wise).
- English interface : you can switch the Chinese models to English without too many issues (some text still in Chinese, but not too annoying)
Do Chinese and ROW models have the same hardware, or are there differences ?
On Russian forums, people try to flash ROW to open up the 3G 900Mhz band, but so far, I couldn't find conclusive information that this actually works.
Taking it even further, is there any reason to go for a ROW(usually more expensive) model instead of a Chinese model ?
And perhaps the most important question of all : can you actually flash a ROW ROM on a Chinese model ?
Most answers I find elsewhere say it should work. But my phone gets stuck and won't even start when I do so. Perhaps I'm doing something wrong, perhaps because it's just not possible.
Update : In recent other posts, users successfully flashed a ROW on a Chinese model, so I'm assuming that is possible.
I invite you all to provide some answers or feedback, because when I was looking into buying this phone, that was my most important question

I have ROW Phone bough and i commandet P780 Chinese version witch is more cheap then my row bought in my country. Half a price. I will not pay shipment because someone i know will bring it from there. I barrely wait to compare and i will tell you all about it.
So some follow up on my testing:
Remember : I'm working on a P780 4Gb Chinese with production date 15/03/14
This means I have to use a different preloader file than the ones included in all roms (at this moment). I that is not done, the phone will not boot (see my other thread http://forum.xda-developers.com/lenovo-p780/help/p780-bricked-flashing-wrong-rom-doesnt-t2749683).
I succesfully installed following ROMS :
- P780_S135_130917_rooted_twrp_gapps : standard Chinese rom, works well, some chinese, but does the job
- VIBEUI_V1.5_1419_5_DEV_P780_rooted_twrp_gapps : KitKat rom, worked very nice but had a huge problem with battery drain. Location services would hang an eat up to 15%/hour. Tried many things, and in the end, I got it more or less stable, but no location services (Google Now, Maps, weather,...). Too many problems with battery performance, so uninstalled
- P780_ROW_S124_140403_rooted_twrp_gapps + SLXROM_v24a-Lenovo_P780 : this combo gave me the purest Android system so far. Good old Android menus and behavior, good battery life, good everything. However, I had a major problem : every reboot, I would get a problem with SIM1 or SIM2 that did not come up. No problem, I could flash a modem like V52 Modem_S920 and the problem would be gone when the phone started up again...only to return on a next reboot. I liked the rom a lot, but that was just not workable.
- P780_ROW_S124_140403_rooted_twrp_gapps : The ROW stock rom, and I must say, I'm liking it. Works well, good battery, and in all honesty I kind of like the Lenovo shell. Nice launcher, nice behavior. I installed XPosed and GravityBox to update some things I didn't like without problems. Oh and the biggest surprise of all : in my SIM1, I see that WCDMA-GSM-900, aka 3G 900Mhz, is enabled, but I'm in a 2100Mhz only area, so I don't know if this is just there but not actually working... Furthermore, I liked the Power and security app from the VIBE 1.5 ROM, so I opened the img file, and extracted the apks, and installed them on this ROM, and it actually works nice without issues.
So for now, the last rom (ROW), gives me a non-Chinese, nice rom that has the 900MHz band enabled (will try to test soon).

Thanks alot for sharing this information with us. Now: can you tell us what are the 2 app original names in system.img?
Found them in the priv-app folder,not app folder (somewhere in system.img,forgot where exactly ?): LenovoPower.apk and LenovoSafeCenter.apk
Lots of other interesting stuff in that folder I must say ?
The power app in vibe 1.5 shows me more accurate timings and has a useful interface to see processes that consume power,especially the keep awake,aka wakelocks, and I like the privacy settings on the security app.but this one seems to crash sometimes because of conflict with the security app of current rom,but still...

Hummm...
Please do backup via spflash tool, i found somewhere on xda, spflash tool can pull a backup file from your rom what you using now. So if something happens you wouldn't worry. You have exactly right rom that always running on your phone.
Do research, 1st of all try flash all file and if ended with bootloop, you can try flash again and avoid to flash BL, preloader, sometimes nvram file.
If you have the right backup file, mediatek is nearly unbrickable, even imei can be write permanently without open your mainboard.

Great tutorial on the, well mainly SPFT, thanks!
Problem I had with CWM (and apparently you have to have the right version for Chinese or ROW), is that although it did boot into recovery, I'd get random errors about /system or /data or whatever else could not mount. It would give errors when trying to take a backup, and it just didn't feel reliable.
TWRP on the other hand, works great, no issues (although it says that it needs to fix root permission whenever I exit it, but no problems).
After my experience with a wrong flash, I do believe the MT devices are almost unbrickable, as long as you have the right combination of files to flash onto it.
After trying like 7 ROMS, I decided to stick with the ROW stock on my Chinese model. Great battery, stable, the storage division is a bit small, I'm running out of internal storage although I have plenty left in built-in storage, but my apps don't want to install there, neither can I move them.
Most important indeed is : BACKUP first
Update on my current P780_ROW_S124_140403_rooted_twrp_gapps ROM :
Although it shows 900Mhz band active, the 3G connection was pretty unstable. It works well for 1 second, then goes to nothing, then back to working well.
So I decided to flash the V52 Modem_S920.
Downside : no 900Mhz (but is it still used in a lot of countries ?)
Upside : 3G connection a lot better and stable. Browsing the internet is fast.
Where I would see a download speed of 25Kb/s to 500b/s to 200b/s it now stays well above 10Kb/s, with speeds well above that most of the time(up to 250Kb/s)
Current test done in Jakarta (with local SIM). Will test again in other countries.
Hi everyone,
I get www getdroidtips dot com often in search results when researching if a phone can be rooted or if a certain ROM works on it. Is it a legit site? They have tutorials that sometimes link to firmwares on a google drive (e.g. stock firmware), so I wonder if it is really legit.
Thanks

My POV: Extracting a ROM from a phone you own is perfectly legal - at least in US, but downloading stock ROMs from the WEB unless offered on OEM's or Carrirer's site is a crime.

I believe even in the US it is legal, at least this is my understanding : "The American implementation is the*Digital Millennium Copyright Act*(DMCA), which includes a process for establishing exemptions for non-copyright-infringing purposes such as rooting". In the EU it is also legal (you are allowed to replace software). Many vendors ship unlocked bootloaders for this reason. Rooting is not the same as jailbreaking on IOS; jailbreaking exploits bugs and rooting just gives you root access via an unlocked/replaceable bootloader.
But my question was more if it is a reputable source or not.

I have been a part of GetDroidTips for more than two years now. We at GetDroidTips usually have all the solutions to any troubleshooting issues and updates on bugs, latest Android updates and more from legit sources. Irrespective if it legal or not to download any ROM, we make sure what information you get is legit. Downloading stuff is always at user's discretion depending upon if rooting or installing a software is banned or barred in one's country and it is truly subjective.
