Auto data on/off

I've been using this phone with the rooted 727 ROW ROM and I had this problem before rooting. The cause is the Lenovo Power Manager app or whatever it's called. Even if you shut it down in its settings page, it will mysteriously turn itself back on. And since it manages multiple things like brightness control, WiFi on/off, Data on/off and Vibrate modes, you don't have much control over these settings when the Lenovo Power app is on.

Solution is to disable the app altogether. Go to Titanium Backup and freeze/disable it. I rooted about 3 weeks back and performed this along with freezing other Lenovo bloatware, and I must say the phone has become usable only after that. No more erratic data/power toggles, no more LAG. I can't check "battery usage" anymore though, since Lenovo must have removed the stock android battery usage page to put in their Lenovo Power app. I have a small widget to give me the battery percentage and battery life without the Lenovo bloatware seems to have improved as well. I used to be getting about 6 hours of screen on time and roughly less than 12 hours of standby (8AM to 7-8PM); but now after removing the power app, I get about the same 6-7 hours of screen on time (all data / wifi everything turned on, screen at 50%) but about 20+ hours of standby. Unplugging at 8AM, it still has about 15% of battery left at 2AM the same night.
[Lenovo K900] Rdmkr:
How is the screen quality of this phone? The size and screen resolution are of course excellent, but does it end there?

A test I've seen of it's contrast ratio wasn't good... In a lot of youtube videos it looks like the screen is off-color and lacking in vibrancy.

How is the real life experience?
[Lenovo K900] mac231us:
Have left data roaming on...no unusual data usage though..but is not needed here for auto data on off for mms..though think on on Samsung/ even miui and cm/aokp builds also this was needed to have auto data on off for mms but I could be wrong
[Lenovo K900] QuBeX:
For all people, I heavy recommend the 903 ROM. You can easily install it following prie instructions and put it in English. The battery drain is better than older builds and there's no lag at all. And if you want more you can use morelocale to put the ROM in your desired languaje, I have it and it works well

Another K900 user here! Love the phone, but it has an Achilles Heel. The Lenovo Power Manager absolutely sucks!

I have been having problems with sync/push email, and found that the power manager would eventually stop the sync, causing me to miss out email! :(

I've since disabled it, and all seems to be operating as normal! Anyone else having problems with auto-sync/push email?
[Lenovo K900] trungduc5151:
go to lenovo power setting --> add email to wihitelist
[Lenovo K900] mydroidfren:
Spent whole night setting up 903 rom finally its done with those pesky Chinese words around. The calender is also non Google so added all Google things back. Good that its almost clean without most lenovo apps more space and seems smoother & faster too. Not sure on battery going to test these few days. Antutu bench still rated same 20640 below Xperia Z.
[Lenovo K900] gooberq:
I have been searching but cannot find it, how do I get power manager installed , I don't see it in settings, is this a separate package?, I have the 620 version ROM
[Lenovo K900] mac231us:
antutu gone down since it got updated...used to be 27k when i first got the phone (may have been chinese or the first row rom...does not matter since june or july been consistently at 19-20k no matter which rom)

however actual use fluidity-wise, 0903 best and chiness roms for a long time now having speakerphoen that actually sounds like one
[Lenovo K900] abcdell123:
Guys please help me. How to unroot and restore back to original rom. Mine was 727
[Lenovo K900] trungduc5151:
Antutu version 3 --> 27k

Antutu version 4 --> 19k ~ 21k

if you don't believe, just reverse back your rom :D
[Lenovo K900] Rdmkr:
people sometimes got 27k with the old rom, but certainly not always. and now people still post 22k scores on occasion...

so imo closer to:

v3: 24-27k

v4: 19-22k

Hi the benchmark are useless they are all fake not so proud ;)
[Lenovo K900] Samyk900:
I installed Real Racing 3 on my rooted Lenovo K900 ROW 727. after 2-3 minutes of playing the game it automatically got closed...

Then searching on XDA forum I found this link http://xdaforums.com/showthread.php?t=2424784.

Tried Smanager and the script Helium 2.2.1 as per the instructions but problem still persists...

I believe but do not care about antutu etc just responding that I thought ROM version did not make difference but antutu version does.

Hi QuBex could you tell me how to work more local thank you ;)

Disabled it, and haven't had any issues since.

Don't really notice a difference in power consumption without it, so its staying off.

Guys!!! Guess what!!! A new update is here!

Just updated from LA_0822 to LA_0922 the update is only 3.78Mb, however installing this update looks like it breaks superuser access!!!

[Lenovo K900] mikey199:
Shows up on my rooted 822 row in settings-about phone-system updates. Haven't tried it yet don't want to lose root.

---------- Post added at 01:28 AM ---------- Previous post was at 12:51 AM ----------

Still 4.2.1. Set supersu pro to survival mode and it survived i have root still! Android said upgrading apps when i restarted. After a random restart and a hard crash I figured what do I have to lose updating. Seems about the same so far...
[Lenovo K900] mac231us:
thanks mikey199...until ROW moves to 4.2.2 and they fix speakerphone will stick w 0903 rooted w play...actually do not see a compelling reason to move but was curious as you never know.
[Lenovo K900] mydroidfren:
dam i just updated to 903....@@! any difference you find in 922?
[Lenovo K900] mac231us:
Mydroidfren...0922 is still 4.2 1.. But 0903 is 4.2.2 see above posts... The date does not tell complete story.
[Lenovo K900] garryweil:
Chinese ROMS supposed to have 5GHz ?

I installed 903 mostly to get 5GHz Wi-Fi. But I noticed there is no support. Does anyone have 5GHz on 903.

Thanks
[Lenovo K900] wesleyrpg:
I haven't seen 5Ghz Wifi working on any ROM so far, whether it be Chinese, LA, or RoW. :(

Lenovo Power is a new build.......
[Lenovo K900] wesleyrpg:
How did you keep Superuser access, i bought the elite version thinking it was a setting called "ota rootkeeper" but this is greyed out on my K900?

hmm, wonder if its a different SuperSU program your using......more info please!!!!
[Lenovo K900] redandwhitearmy:
Indian version is what i am waiting to get my hands on. :)
[Lenovo K900] ilsilencio:
I also intend to immediately buy that version of K900. Can you advise the best places to buy this phone in India? Of course, through the internet because I live in Europe :)

Regards!
[Lenovo K900] redandwhitearmy:
Well i am not sure which Indian online shops deliver in Europe ... Ebay international sellers are there but not sure about others...
[Lenovo K900] redandwhitearmy:
Launched in India today . too much expensive at Rs 32999...for same price i can get xperia Z ... disappointed

[Lenovo K900] ilsilencio:
nikhiltanwar can you give me the address of an online store where I can buy and send to Europe this smartphone? If you are in India, maybe you could help me with this?

I would be extremely grateful!

Regards!

Konrad
[Lenovo K900] redandwhitearmy:
In which country u want this phone?

BTW i am warning you, people dont get stuff delivered from India. It will be really expensive (near about price of galaxy s4 which is available for 39000)... getting it from China or Indonesia etc. will be cheaper . and lenovo is making google play available on all versions.
[Lenovo K900] bobr76:
Update from my side:

I got the international ROM to work on my chinese imported K900. It was painful process with lots of trial and error. Main source of info and ROM is here http://www.lenovohome.net/forum-515-1.html

To summarize, now I have fully functional Google package on it and everything seems to work from playstore. No more sideloading needed.

And Encryption works with corporate emails already functional.

There is one drawback here, this rom currently does not have root. I think it's just matter of time some rooting tool will come online. But honestly, I don't need root for now. Rather see everything working (as it should be in first place) and I am happy :) :victory:
[Lenovo K900] mclife:
Thanks for sharing. The device encryption part is interesting to me as its required for some native corporate email clients. I'll wait for root before switching. Pretty much fully functional with root using the ROM in the OP.

---------- Post added at 12:03 PM ---------- Previous post was at 11:43 AM ----------

Also is this international ROM still skinned and with Lenovo launcher?
[Lenovo K900] Cyman:
Could you please share this "painfu process" with us? I don't know how to flash this tar.gz-file. Thx!
[Lenovo K900] bobr76:
Well in true corporate world rooting is not allowed. My previous phone was rooted and had encryption enabled and it worked fine. But if company IT would start sniffing and found out my rooted phone then it would be different talk :)

Anyway I'm waiting for international rom root and will probably unlock it.

Yes, this international ROM is still skinned and with Lenovo launcher. Good thing is it does not have any bloatware like chinese version has. And it performs couple hundred points Antutu less comparing to Chinese ROM which is not visible in daily use...
[Lenovo K900] MacGuy2006:
This is great news!

Bob, do you mind posting step-by-step instructions on how to get the international ROM on a Chinese market device?

Thanks!
[Lenovo K900] bobr76:
I also didnt know what to do with that file. It took me hours to figure it out. Thats why I say painful process :)

So here it goes how to convert chinese K900 into international.

Surce of rom from chinese forum http://www.lenovohome.net/thread-167295-1-1.html. Of course use google translate :).

Get the ROM here http://pan.baidu.com/share/link?shareid=554921&uk=2335146322

Uncompress with password bbs.lenovomobile.com

You need to unpack this tar.gz with winzip or winrar. At the end you get unpacked file in .inb format.

Then you need to transfer this file to phone storage to the folder called /sdfuse (create the folder first if you don't have it)

Make sure battery is above 60%.

Turn off phone.

Hold volume down and power it on (choose droidboot)

When rebooted into droidboot choose the sdupdate.

First boot after flashing takes a bit longer but be patient, it will work.

Enjoy your new phone :).

p.s. during flashing I saw an error it could not delete some .tmp file. But looks like that did not affect final result.
[Lenovo K900] ajftl:
Where is this rom you talking about? I think u can use the flash tool to load it like the one we did here

Link please
[Lenovo K900] bobr76:
I updated my previous message with link to chinese forum - source of rom.

No, you cannot flash this rom with flash tool. You need to follow the process I wrote above.
[Lenovo K900] mclife:
OP, can you stick those instructions in the OP?
[Lenovo K900] blubx:
battery life

Can someone tell bout battery life for this phone, couse i lean to buy this phone so so badly
[Lenovo K900] josealbacete:
This rom is multi language?

Bob?

Thanks for your information!

One question the rom already comes with all languages ​​or only Chinese and English?
[Lenovo K900] bobr76:
Once you are doing initial setup it recommends only chinese, indian, english and some other I dont recognize.

Then in the language settings you have many more available (spanish, french, russian and more others I dont recognize).
[Lenovo K900] ilsilencio:
Please, someone finaly share a video shot by Lenovo K900!

I do not know how this at all possible, but on youtube there is still not even a single movie in FullHD recorded by this smartphone!
[Lenovo K900] josealbacete:
Someone has already been root in the new firmware????
[Lenovo K900] jejemc:
hello QuBex and thank you I will try this re aujourdh'ui because I was not any language is available ;)
[Lenovo K900] rajivmishra13:
I ran the ota update, phone rebooted did it thing but showed a failed message, something related to chrome ( i have chrome OS uinstalled long back once i gained root ). It rebooted back into my existing version 822 ( rooted ) and said ota update failed.

:cowboy:
[Lenovo K900] rajivmishra13:
Thanks.....all is done except Google play store. I did copy all files as said in step9.

What could be missing?
[Lenovo K900] prie07:
hi...

if you didn't do step no 9, some applications can't install from PlayStore cause incompability issues :)
[Lenovo K900] rajivmishra13:
In instructions...it doest say anything about fixing permissions. I have Google play store working now...only gallery and Google drive keep crashing.
[Lenovo K900] tukulll:
I did exact steps from the guide above, sdupdate, change language to english, install included root browser, copy/ paste files included, re-mapping permissions, no error.

everything went well. gallery runs fine here.

fyi : i did this twice, my phone and my friend's phone. everything runs great, battery life now is much better.
[Lenovo K900] dabdob:
You need to change the permissions as well (step 10).
[Lenovo K900] mac231us:
Rajiv see step 10 fix permissions

I think I even changed permissions of the files from the gapps rar before putting them into system/app though this may have been unnecessary..anyway prie07's steps are all correct
[Lenovo K900] mikey199:
Using supersu pro by chainfire. I just went in settings and checked the box marked survival mode. Everything went good.

USB OTG Capabilities

Hi to all,

I would like to ask if your Lenovo k900 device recognize usb flash drives?? I have bought an otg cable, but unfortunately the only thing that was recognized by Lenovo k900 was a usb-mause (and not different usb flash drives 4,8,32 gb )….

Version: K900_1_S_2_009_0145_130508

Can someone help me??

Thanks in advance
[Lenovo K900] rajivmishra13:
Hi...

Step mention the change and I did that but to get everything working..I had to also fix permissions for all files copied at step 9.

Anyway all is done...but still got lot of Chinese here and there...like the system fonts....in contacts with me in English...some Chinese cha rather shows up...then we have Siri like voice app in Chinese...etc. Is there a way to set system to only English!
[Lenovo K900] mikey199:
It would take too much work to get rid of all the chinese. Maybe use the ROW rom. It's for the non chinese of the world.
[Lenovo K900] Trancexplant:
...

Quick question: What's the difference between this and the similar process listed on Page 14 of this thread (Post 133)? Is one method better (aka more reliable/less risky) than the other? (apologies if this has been covered before)

I ask because the flash tool method already bricked my phone once (got stuck in USB mode, requiring a factory repair), so I'm being extra cautious this time around. Thanks in advance for the help and/or info.
[Lenovo K900] wesleyrpg:
anyone noticed the 'extra' power setting in Lenovo Power when the K900 is rooted?? :D
[Lenovo K900] dimedevil:
yup ... i did

right now I want to try using Save Root from Android Root Toolkit and upgrade to 922... but I dont have the guts to do it :D Just afraid my root would be gone after the update
[Lenovo K900] jejemc:
Hi no you will not lose root after update
[Lenovo K900] dimedevil:
yep I know... but reading [MENTION=4603331]mikey199[/MENTION] post said that he still on root with Survival mode on supersu pro after upgrading to 922.... because I don't have pro version, Android Root Toolkit should do the same with Survival mode, can restore root....
[Lenovo K900] zuljiano:
How comes 903 is JB 4.2.2 and 922 is 4.2.1?

I successfully upgraded from 822 to 922 and still have the root ... I'm using Android Root Toolkit to Restore Root (Save Root before updating to 922)...

if you are using Supercharger Script, you have to Unsupercharge your phone before updating.....
[Lenovo K900] BigDogPooh:
Does this ROM contain the lenovo super camera. The reason I ask is that I'm looking for some files associated with the camera. It was ported over to the galaxy s4 but not all functions work and I wanted to see if I can get all functions working. Any help would be appreciated.

how did u update it ? i mean i have rooted 0723 ... and it says latest in update ... how to get 922 ?

Can anyone post a download link to 922 ROW ROM rooted with Google play store, maps, etc. I have 903 now, after I install it according to prio tutorial, but there are still Chinese characters here and there.
[Lenovo K900] dimedevil:
just download the 822 root, set SUPERUSER to allow, use sdupdate, download Android Root Toolkit via play store, save root with it, update to 922 (less than 4MB), restore root with ART...
[Lenovo K900] QuBeX:
It seems that http://www.lenovomobile.com/opensource/ is working again but with no changes in the k900 source.

[Lenovo K900] mac231us:
Thanks tukull..I don't speak Chinese but I respect all languages and cultures...

it is ironic given Lenovo now a Chinese company produced a phone (from the way things look) firstly for China and then for other markets...and yet...

to those don't like Chinese...fine...just don't call it 'junk' and other choice words...

in many ways English is 'junk' too..illogical not phonetic etc...people who try to learn it for the first time find it a very hard one to learn (an amalgam of Scandinavian, French-derived almost 40% etc etc..even words from India)

people just speak it because of history (colonization etc) and circumstances (technology-driven world etc)..it is the way things are..things that get big get bigger..

Germany, Austria, Spain, list goes on..most people you ask on the street do not even speak English (once you get away from the fancy/business areas)

anyway...that is why we need a moderator...and we need folks who do not blast away on ignorant vitriol

There was mention of 4.3 in one of the lenfen boards.. Wonder if that is the beta..like 4.2.2 was beta on August 5 as first an ota update
[Lenovo K900] mikey199:
Not sure about lenovo tools, is that the windows program? Anyways to freeze apps you need to be rooted and have a superuser app installed. You can download and use App Quarantine from google play for free. My preference is using titanium backup but you must use the pro(costs money). Free version doesn't freeze apps. If i helped you please hit the thank you button.
[Lenovo K900] Samyk900:
well, you can also use antTek app Manager. Its completely free but need rooted device

phone runs hooootttt.....than usual. especially when playing intensive 3D games eg. asphalt 7-8.

even when I disable the HELIUM script and reboot, phone still runs hot while reading SMS texts and some chats on Whatsapp.

now the fun part:

try to disable/ uninstall HELIUM script, then install antutu CPU master free. set cpu to 800MHz or 933 MHz with userspace option.

again, play some intensive games, guess what, the phone is not burning anymore, but games still silky smooth ! multitasking still great !
