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.

Flash custom ROM
Video with links to files, and other hopefully useful info. FOR A SOLUTION!
I had a really long post with useful info containing an answer maybe not "the answer" Wanted me to instead post a comment.. Below are the instructions on how to do it according to a Youtube Video I found. While I haven't tried this method, It looks sound to me, they've included all the files needed in a link to MEGA. I'll re-share without the password / decryption key if the poster agrees only.. I do highly suggest Phoenix ROM if you're on a kltevze, it come included with eveyrthing you're looking for and I've used it before In fact, I tried it last night but was unable to get into my phone past the boot password screen I think because the system ui kept crashing. while I have used this version, I may try twelve, since I prefer AOSP or LOS based roms, I want as light as possible maybe even removing google and going with MICRO G which I used fairly successfully for over a month, It isn't perfect, sometimes the location addon apps crash, but there are many, and it may just be that the ones I was using crashed, and not the ones you need yourself.. But MICRO G is worth the piece of mind to me coming from an encrypted phone, No I have nothing to hide really but Alphabet/Google already know enough about me through the use of their "FREE and Very Handy I might add, Services Ahem) By the way, Phoenix can be used with either an unlocked bootloader or safestrap if not.. Just get the right one.. I may end up going with a rooted deodexed TW rom, and add xposed to get the features I love from RR and other LOS based ROMS. With further ado, heres the link to the youtube instructional video I found, I really wish it was written out or could simple installed as a flashable zip which shouldn't be hard to make, but it is what it is for now.. And again seems correct to me if you don't want o go with a custom rom like Phoenix for kltevzw.
Well upon testing the Youtube link didn't play so here it is both Title for searching and another link. Install Galaxy S7 Touchwiz on S5! (Marshmallow) /URL]

I used Heimdal to flash to a more recent factory TW before flashing Phoenix which requires at least PB1. I think. Check their OP under user JKRUSE or near the top of the VZE dev thread.
This is Heimdal as found in synaptic from a buntu based distroand should be the same in any Debian based or any other distro for that matter as I've found it in many repos for different distro's, I think a ppa is available with newer builds, but don't hold me to that.
Heimdall <- commandline version.
Heimdall is a tool for flashing firmware (aka ROMs) onto Samsung Galaxy S
devices over a USB connection. It accomplishes this using the same
protocol as Odin, Samsung's internal Windows-only firmware updater.

And of course there's a GUI too.. heimdall-flash (1.4.1-2) unstable; urgency=medium
This package includes a Qt-based frontend for managing Galaxy devices.

If I do either agian soon, I'll report back with results. Again, I know Phoenix worked fine. But I'd imagine a plain TW rooted ROM that you debloat yourself and maybe add Xposed for many features found in Phoenix and in AOSP/LOS based ROM's such as RR/CR-DROID for those who prefer additional tweaking and other enhancements. Again I trouble just last night with the latest V15 of Phoenix on boot and don't know why other than my fully ecnypted device and password on boot feature But either way again if you test before me let me know the result as well. I do need a new battery for mine since it's the one it came with but that's a story for another thread, when I bought my S5 last spring for beans, (with the unlockable BL, I had to have it since my S3 had died. and I couldn't afford a new phone) and I could easily get a day plus when service is good with about 4+ hours SOT. But lately I'm using charging by the end of the day. Haven't decided yet on a stock Sammy battery or a more expesive, Thicker, heavier, but much longer lasting extended battery.
Sorry for such a long winded post. All my posts are this way if you know me. I do apologize and need to be more brief but I'm more of a lurker and searcher for what I need to know and post very seldom especially with this much what I think could be useful to someone.
If it happens to be useful please hit the "Thankss" button, it could help here, and even when looking for a job as I am... Hahahaha.. Getting laid off work blows in my area of the country.
Thanks and Happy New Year to all those who celebrate it during this time of year, if not Happy New Year when it arrives and I wish the best for everyone on the Planet. Stay informed and don't believe everything you read/hear/watch... #NoAgenda #ITM.

Hello!
I'm a bit of a noob when it comes to android development, but since BLUBOO pulled their Android 6.0 update for their 5.1 Picasso 3G phone, I was wondering if a port would be at all possible? I found many guides on the internet but I've bricked a few phones in the past and thought I would ask to see if anyone else has tried/achieved this at all.
I found a ROM that the Picasso 4G uses that is a 6.0 rom - Would this be okay to port or am I going to overwrite the bootloader or whatever I did to my last phone and have another brick to add to my collection, lol?

I know, this thread might be dead for a long time, but since I stumbled upon this thread in order to resurrect my good ol' Picasso, there might be people finding this interesting:
on 4pda, there can be found some custom roms for the Bluboo Picasso 3g. There is also a 6.0-Rom.
https://4pda.ru/forum/index.php?showtopic=711170&st=12120#entry67242059 (I use chrome for website translation)
hello, I bring you a mini tutorial to recover this mobile. In the file is the tutorial in text format, both in English and Spanish.inside the zip is the rom stock with android 6 for this model, it is installed with sp flash tool.
added installation of twrp with android 6.0 (rom bravis), and custom rom 7.1.2 crDroid.
This custom rom is amazing and has many customization options and the system is rooted by default.

"I would like to add that the work is not mine, all the credits and thanks to the guys at the 4pda Russian forum. I'm just sharing it because this was picking up dust in the cloud".
Any chance somebody can share sources for this phone? I am trying to build a fresh ROM for the phone.
bernavaldiesel1, thanks a million man, I've been looking for the working twrp for ages
