BOOTLOOP !!

Hi, this is my first post, so please be understanding.

My Lenovo K900 has bootloop, I made wipe and factory reset. I didn't know what to do with it. It hasn't sd card so I can't copy ROM. Please help !

Hi,

Does the system.img wipe my lenovo K900 if I try to root my 0047 International Rom ?

Hi guys, I have flashed 620 ROM (system.img only via fastboot) but now I'm having audio issues. When I want to play music the audio is full of noise and it seems to be going little bit faster. Haven't you came across this problem already? Maybe I should flash also something else from the 620 rar? Or flash the whole rar somehow? (how?). Thank you!
[Lenovo K900] mikey199:
708 seems fine only tried a few but audio matches up. I use mxplayer and x86 mxplayer codecs if that helps. Also contact manager only crashes 2-3 times a day not bad doesn't get in the way phone and contacts work fine other than the couple random crashes a day from contact manager.
[Lenovo K900] amoyan:
620 was OK for me. I used the manufacturing flash tool.
[Lenovo K900] mac231us:
does it make a weird sound when booting up also? I got this twice...both times had diff versions of unrooted and rooted roms (rooted flashed over unrooted)

when I flashed a 6/20 rooted rom for example over a different date version unrooted rom..i found i needed to have the same versions of unrooted and then rooted roms flashed (otherwise i would get all kinds of sound artifacts)..this is when i used the fastboot method (is this what olegfusion refers to in the versions he used..see OP..where he says "..make sure you flashed 47 INB file already..." for flashing the rooted version of the rom he used)
[Lenovo K900] cyber-mythius:
Could you give me link for unrooted . 620 version?

For the manufacturing tool - you load full rar as you download it or you put there only something from the rar?

in this review it says it has Removable Storage (maximum)	32 GB :confused::confused::confused::confused:

r they providing external mcard slot in new models????
[Lenovo K900] cyber-mythius:
Lenovo presented somewhere this machine with dualsim and sd card slot. This is the reason, why there is actually misleading in the specs all over the Internet. To the first wave Lenovo launched version with 16GB and no sd card. You could wait a bit and then buy the better version, but I haven't been able to find it in Shenzhen neither in Wuhan (China).

Hello all,

I'm planning to buy this phone but bit confused about memory card. GSM Arena says it has a memory slot http://www.gsmarena.com/lenovo_k900-5241.php

Is there really ? Or different versions of the phone and if so, could you please point me in the right direction to get one with memory card ?

also found a forum where (and i had this till recently never paid attention accidentally deleted it) apparently (again apparently) a tool to root the k900..know this exists for example for the k860

http://bbs.loorin.com/thread-8090-1-1.html

there is a program that supposedly pushes superuser etc

adb push busybox /system/bin/busybox

adb shell chown 0.0 /system/bin/busybox

I own the Titanium version of Lenovo K900.

Certain areas of the back cover did heat up when I made a 50 minute video call on skype over wifi, the battery too drained quickly but the audio & video on call was flawless considering my broadband speed is just 512kbps.

---------- Post added at 02:00 PM ---------- Previous post was at 01:30 PM ----------

I bought a Lenovo K900 Titanium Color International 16GB Version with Google Play Store Support, but no SD Card Slot.

Few issues that I am facing are:

1) Call drops randomly after about a minute.

2) When I connect the K900 using the supplied USB cable to my laptop, a window pops up on my laptop screen in Chinese language.

3) It has a utility app called the cleaner which shows that memory in use is 62% despite a handful of apps running in process services.

The highest memory usage is by Lenovo Launcher at 190MB, Settings at 101MB & Android Keyboard at 66MB.

6 other processes use just around 80MB but memory usage still shows 1.2GB of 2GB RAM.

Any advice is appreciated,

:good: Cheers

[Lenovo K900] vanhoe:
You might have to use dedicated apps for that, since flash is not supported in android by default. Most popular websites have the HTML5 version of the player so you can use that also.

Or try some solution that can be found in the forum.

Hello everyone. Looking K900 rom with Hungarian language. I tried several rom, but none of them is no Hungarian locations. Thanks for help.
[Lenovo K900] MacGuy2006:
I am not aware of any official ROM with Hungarian. The main European languages in the international ROM are English, French and Spanish, plus a couple of the Slavic ones (Russian and Ukrainian).

Just received my phone today. Currently using stock rom, just want to test everything before rooting. I noticed the phone gets quite hot on the upper part of the phone when downloading stuffs over wifi. Other than that no issue with it yet.:good:
[Lenovo K900] Sw33t_Lov3r:
Thanks. Seems like a good online market. And USD 540 not not a bad price. I might end up ordering as seems like Lenovo is playing "Let's see who cries louder" to pick the next release country and my country (Peru) will get it on 2014. I think I hate them already. I'm quite sure I'll have to go with the Galaxy S4 for my on-contract upgrade on early september u.u There's no better option, it's quite nice though.

A bit of teasing in their FB page:

https://www.facebook.com/photo.php?fbid=10151618664524635

"The Philippines just got it--will your country be next?"

Can't they just publish a list of countries on which the'll release it???????????? -.- Are they brainless?????????????????:cyclops::cyclops:!!

10bit chinese cartoon comparison K900 vs Nexus 7 - MX Player

So I did a comparison for 10bit video decoding. The video is from http://www.nyaa.eu/?page=view&tid=451266 (because Underwater=Daiz), I used H/W+ decoder for Nexus 7 because on H/W decoder the video can barely play it if it's doesn't freeze after a few frames ; on S/W there's desyncing between audio and video.

left:K900 right:Nexus7
[Lenovo K900] Sw33t_Lov3r:
And what is your conclusion after your tests?

I wonder why so little resolution screenshots. Anyway, it'd be interesting to know WHY the Intel Atom cpus can play these

problematic 10 bit videos so perfectly. What is that makes them capable of doing it when the others struggle so bad?

A codec? A sofware? A chain of mice pulling really hard? I'm afraid I'm not an encoder :D

Who can know about it?

I tested such videos (published report in pages back on this thread) with my Razr i and it played them flawless and

effortlessly; the 720p ones, and the 1080p ones with some minor flaws (all in S/W). Interesting...

Any other format of HD video (8 bit) plays with no problems in any midrange device, but the 10 bit ones are their

nightmare :/ I wonder why.

Some go post these doubts to a audio-video forum :D! Please!

- L.

Pd: MX Player developers published an improved build/version for testing and it has a noticeable

improvement in the 10 bit videos playback. Check it out in their Google forum, if you didn't already.
[Lenovo K900] vanhoe:
Conclusion:

x86 SoC phone is the best choice for 10bit video play back, though it seems like ARM is catching up also.

From the forum posts that I've read, it all comes down to HEVC support in the chip itself. The Samsung Galaxy S4 (the Exynos octa version) seems to have this feature implemented, though I haven't seen it in action yet.

http://gizmophiliacs.com/2013/03/samsung-galaxy-s4-to-come-with-hevc-h-265-support/

I have been searching the forum for a solution and cannot find a resolution for this.

Hello!

Which FW is better and more stable:

newest K900_ROW_1_S_2_009_0101_130708 or K900_1_S_2_009_0204_130627_DVT3_CPU?

And any idea what rom is used here:

cose its multilanguage.
[Lenovo K900] MacGuy2006:
The 627 is a Chinese ROM. It does have English-language option, but it contains many Chinese-specific apps and doesn't come with Google apps by default.

The 708 seems like an unofficial release originating from a Russian forum and it does have some issues.

Probably safest is to use the 620 International ROM.
[Lenovo K900] IceGoal:
Agreed. I reversed back to 620. Better than 708 in my opinion.

OK, Friend grabbed my device (he's in China) and i instructed him to update to 0620 ROW through the SDFUSE trick - worked great!

He's now using it for a few days until he gets back here and I'll take it from him.

In general, he is very impressed with it - So much that his other friend decided to buy one himself.

Lenovo REALLY need to market this in more countries.

[Lenovo K900] dabdob:
Isn't there an app on Google Play that would switch the phone interface to virtually any language (has many languages)? I think it is called Locale select. Or is it because the 620 is a rooted ROM, the app won't work?

I recently bought a Sony Xperia E Dual for my mom, and it didn't have Arabic, so I used the app, and it was Arabized flawlessly

I rooted my K900 with the 620 ROM from a baidu link (sorry am not allowed to post a link). I am facing the following issues with the 620 ROM from that link.

1) The superuser application is in chinese. I was able to use root by guesswork. But it keeps on throwing messages in chinese some times about power application about which i am not sure what to do.

2) Phone randomly becomes unresponsive while unlocking it with PIN enabled. I cant enter the pin and i sometimes cant even take the call. The only way out is to long press the power button till the Shutdown/Reboot screen option appears. After that it starts working

3) The number of ringtones seems to be lesser than the stock ROM i had (Indian version).

Is there a complete English version somewhere since the one on earlier pages (pg 40) doesnt seem to be available.

International ROM 727 update available

I had 620 international ROM. I did a system update check under "About phone" option and there was an update available: K900_ROW_1_S_2_009_0131_130727. It's only 19.73MB. I did a direct download and upgrade on my K900. I don't know yet what's new in this 727 ROM, just thought to share this news with you guys. I will report back any findings of the improvement after I use it for a while. Hope it's good. At least it's an official release from Lenovo!

[Lenovo K900] mac231us:
Thanks. The update failed on assert (updater script) so think this works on unrooted rom? Was surprised to see it even showed an ota in the first place. Need to put unrooted then do ota then root...well Bob will figure it out am sure. Thanks Bob in anticipation!
[Lenovo K900] bobr76:
Yeah update might not work on rooted rom. My update went through ok as I cant have root due to corporate email policy.

Things are getting complicated here guys. I can't see where this OTA goes and I have no way to copy/download my updated rom now. This means I won't be able to root it :(.

So for those users on rooted 620 better stay there for now. If you want new rom rooted we need to wait for full rom package to pop up somewhere. Then hopefully I will be able to root it...
