For upgrade you don't need Active sync , rather while upgrading active sync is atomatically turned off,For upgrade go into boot loader mode in your phone than connect USB cable,then see on your phone you'll see small usb appearing at the bottom of the bootloader screen,if it's there tha you can flash any rom you like.

but,sure you wud have to establish connectivty between phone and Pc via Active sync if you want to add or install any more applications or software.but it's not required for upgrading or flashing a Rom.

Which version of Active sync you are using and which Windows?,download the latest ver 4.5 and install,as for windows,do all your upgrades using WinXP Sp2. You might require to upgrade Windows Installer version 3.1,update it through Windows update from Microsoft website, good luck
[8125, K-JAM, P4300, MDA Vario Software Upgrading] owlmastser:
:) Thats another problem lol getting the usb on the booter loader screen but when I run the button rom it can find it think i might just buy another sync cable

and hope for the best.

[8125, K-JAM, P4300, MDA Vario Software Upgrading] zabardast_1:
what exactly is the problem you are facing, is it the usb connectivity or you cannot sync through active sync ?,how did you sim/cid unlock your phone ?

well,what I can make out of your post is that you are not able to establish connectivity through Active sync,but your usb cable is fine and you want to upgrade ?does your phone gets charged via usb ?what you mean by 'when I run the button rom it can find it,find what ?

ok,do you see usb while in bootloader mode ?
[8125, K-JAM, P4300, MDA Vario Software Upgrading] owlmastser:
forgot to put in running WinXP SP2 and Win installer 3.1
[8125, K-JAM, P4300, MDA Vario Software Upgrading] owlmastser:
unlocked with loki over a bluetooth connection yes it will charge through usb and the usb shows up in bootloader mode thx for your replies
[8125, K-JAM, P4300, MDA Vario Software Upgrading] zabardast_1:
ok as you say that usb shows up in bootloader mode,than what problem are you facing while flashing to your device ? while coonected to the pc via usb and it shows in the bootloader there shudn't be any problem than to flash ?:confused:

Are you sure you carried out the CID unlocking method correctly and your device is CID unlocked.To check download WST tool and verify the present status of your phone.
[8125, K-JAM, P4300, MDA Vario Software Upgrading] owlmastser:
Hi zabardast_1 thx again for replying when in boot loader mode and run the upgrade rom it look to check pda info and comes back with error 260 unable to connect to pda I have tried the WST tool to verify the unlock and it comes back saying they are i"m thinking it must be the cable as the cable that came with it from ebay is a motorola cable and the other cable i have is a universal.Handy tool that WST

Ok,

ERROR [260] : UPDATE ERROR

This error occurs when there is an “open port error” before upgrading the ROM image.

Solution: You can reset the device and run RUU again. If you still encounter an “OPEN PORT ERROR” again, reset your computer and try again.

Soft reset your phone and try to flash again or reboot your Pc:-

1. Make sure your phone is not Connected to the PC and remove the dummy card or SD/MMC card

2. On your Desktop PC, open Microsoft ActiveSync, then go to File >Connection Settings >Remove the Selection from “Allow USB Connection with this desktop computer”

3.Try to go into boot loader mode on your phone

4. Reconnect your phone to the Desktop PC using the USB Cable (Don’t use the Bluetooth for the Upgrade)

5.After reconnect to pc via usb cable you'll notice small usb appear at the bottom of boot loader screen,if present...

6. Run the Upgrade again and it will work fine without any problems.

While upgrading, the ActiveSync program will not go on, however the upgrade is running.

Have you ever before used these usb cables for upgrading or accessing your phone through Active sync ?,if yes then it'll flash also and if not than it's a usb cable incompatibility problem,get a new compatible cable and try.good luck

I'll also advise you to turn of any Anti virus program and disable the Firewall too as it hinders the flash and don't do anything else with Pc and phone while Flashing .
[8125, K-JAM, P4300, MDA Vario Software Upgrading] owlmastser:
Thx again nope never used the cables with this phone just got it from ebay on monday and haven't been able to connect it since i got it have done all that you have mentioed that's why i think it must be the cable.Get a new one today so will try it out tonight will let you know how Iget on :)

Hey Zabardast_1 no go on wizard still getting error 260 open port error even with new cable have tried now on 3 computers only thing I can think of now is there is something wrong with the usb port on the phone
[Xiaomi Mi 4C] heykal:
Hey guys

According to the company they used 2 different camera sensor in this phone which is completely depending on your luck which one you will buy:confused:. So i am asking you guys if anyone have this phone with samsung sensor . make a little review and upload some samples. and let us know is it same as sony one.because the sony sensor performed very well in low light.

Thanks:D
[Xiaomi Mi 4C] ermacwins:
You sure there are 2 different sensors?
[Xiaomi Mi 4C] ckret:
edit:

[IMG="mi4c"]http://en.miui.com/data/attachment/forum/201509/22/172559br999rdqgmd7lnag.jpg[/IMG]

its a sony cam with samsung sensor
[Xiaomi Mi 4C] ermacwins:
So basically everyone will have the same camera?
[Xiaomi Mi 4C] heykal:
unfortunately i can't insert link or image here because i am new user and xda think i will spam :D but . in the you can google "mi 4c camera sample" the 3rd site is phonearena that publish some samples of the mi4c cam and write a little review this is part of it:

"Mi 4c is equipped with a 13MP primary sensor that is produced either by Sony (IMX258) or Samsung (the S5K3M2)"

in addition there is photo on the mi forum that confirms this. i wish i could insert link and image .
[Xiaomi Mi 4C] ckret:
edit: whatever i dont know
[Xiaomi Mi 4C] Giocarro:
Whatever camera sensor the Mi 4c have my guess is that it will probably perform like Mi 4 and Mi 4i, that are above average, good but not excellent (at the level of Samsung S6 or LG G4 for instance).
[Xiaomi Mi 4C] Stevex26:
Is it possible know which sensor there is on the phone once that you have it?
[Xiaomi Mi 4C] lopusina:
If you have parts at home you could, but i don't think you will have it.
[Xiaomi Mi 4C] ermacwins:
You should be with Aida64 https://play.google.com/store/apps/details?id=com.finalwire.aida64

It has a section about the camera
[Xiaomi Mi 4C] keatbo:
Hey Guys, I would like to know what is the purpose of the small dot beside the camera?

Is it alright to cover the dot with the casing? Thanks in advanced.
[Xiaomi Mi 4C] Flaxe:
The small hole next to the camera is a noise cancelling microphone. I'm not exactly sure what consequences will occur if you cover it with a case... I probably wouldn't cover it, but I guess it's not a very critical component.
[Xiaomi Mi 4C] keatbo:
Thank you for your information. Now I can purchase a case without worrying about the component. :o
[Xiaomi Mi 4C] Stevex26:
Unfortunately, Aida64 doesn't show information about the sensor.. I wonder if there's a way to know it.
[Xiaomi Mi 4C] Flaxe:
I think there might be a way to find it by looking in the "/sys/bus/i2c/drivers/" folder. There are a number of folders here, but one of them is the sensor I think (at least for some other android devices)

In my HTC One X, I got a folder named ov8838, which is my sensor. Maybe someone with a Mi4c can have a look if you find anything similar?
[Xiaomi Mi 4C] hartec12:
dmesg

check dmesg command in terminal after reboot

i did so and found imx in listing
[Xiaomi Mi 4C] Stevex26:
Thanks for replying. I looked in that folder on my current phone just to try (I'm still waiting for my Mi4c) but there are several folders named "ov..." and "imx...". I searched every name on Google but some of those are sensors with a resolution that doesn't match my phone's sensor , so I can't understand which is the right one.
[Xiaomi Mi 4C] Flaxe:
Oh okay, that's strange. I'm not entirely sure if it's a "reliable" method, but it works for my HOX at least and I know it works for some other devices as well.

Would be interesting to see if it works for the Mi4C :)
[Xiaomi Mi 4C] rob rich:
You speak from Moto G? Doesnt it have a Sony Camera? Could be the IMX... folder. And OV... for OmniVision, often used in front facing cams...
[Xiaomi Mi 4C] Stevex26:
Yes I'm using Moto G 4G right now. There's a total of 10 folders called 'ov' or 'imx' so I don't really know which are the right ones. I'll look on my Mi4c once that I have it!
[Xiaomi Mi 4C] rob rich:
Yeah, i'll do the same when i get it (hopefully next week) :)

And hopefully its the Sony one
[Xiaomi Mi 4C] heykal:
Do you see the device section ? The first item is primary camera and it has many information about the sensor.
[Xiaomi Mi 4C] Stevex26:
Yes but it only shows the number of megapixels and other information, not the sensor's name, like 'Sony IMX..'
[Xiaomi Mi 4C] vipercubic:
You can check it just by opening a file located in /sys/android_camera/sensor

Please everybody check and reply!
[Xiaomi Mi 4C] Stevex26:
I can't find the 'android_camera' folder in 'sys'.
[Xiaomi Mi 4C] rob rich:
Maybe it just works on mi4c
[Xiaomi Mi 4C] vipercubic:
I don't have my mi4c yet, but this is the way i've checked most of my android phones. Works in Samsung, Sony and HTC for sure.

Bummer :confused:
[Xiaomi Mi 4C] rob rich:
I use an old Galaxy s advance with JB 4.1 till my Mi4c arrives and i also dont have that folder in /sys
[Xiaomi Mi 4C] vipercubic:
Weird!
[Xiaomi Mi 4C] ermacwins:
I don't have it on my nexus 4
[Xiaomi Mi 4C] wingsfortheirsmiles:
I decided to try to look myself for the sensor type on my Mi 4c using a method I found elsewhere on XDA here

Eventually I found a device name in /sys/bus/i2c/devices/7-0060/name called cm36686

This appears to be a proximity/light sensor manufactured by Capella Microsystems; I couldn't find any references to Sony or Samsung other than on a random github kernel source for the Galaxy S5 Mini - could this phone be using the S5K3M2?

Just to add that I confirmed that my Mi 4c was genuine using the MI Verification app/website check.

Can anyone else confirm my findings? You should be able to determine the sensor you have using the instructions above.
[Xiaomi Mi 4C] bibihub:
Got the same thing by using the terminal

su
dmesg|grep -i sensor

I also tried things like camera but I get errors messages about not being able to read the name..

I didn't find anything about that sensor though
[Xiaomi Mi 4C] bluppfisk:
Does looking for files make sense? Since the OS comes for phones with either sensor, it's likely to have drivers onboard for both devices, or am I wrong? The dmesg seems more sensible, but I'm not getting any useful info out of it.
[Xiaomi Mi 4C] rob rich:
I found it :)

Its in the DMESG.log

IMX258 is the Sony Sensor, ov5670 is the front facing sensor from OmniVision

If you open your DMESG in a Browser (i use adblock Browser) you can do a in-page search for ov5670 (because this sensor should be the same in every Mi4c) and some lines over it there is your rear camera sensor. Dont know how the Samsung sensor is named. Good luck :)
[Xiaomi Mi 4C] bluppfisk:
where is it?
[Xiaomi Mi 4C] rob rich:
Look at my edited post ;)

And though i have the Sony sensor, my pictures in low light are blurry too when there is minimal moving :( i think the shutter speed is too slow
[Xiaomi Mi 4C] bluppfisk:
Yup but can't find the file.

I ran 'dmesg' from the terminal, then used 'find dmesg' to find the log, but it says no such file or directory. How is the dmesg.log generated, and then in what path is it located?

---------- Post added at 09:46 AM ---------- Previous post was at 09:43 AM ----------

Never mind, found it via

dmesg | grep -i imx

It also says imx258 probe succeeded.

I installed CM12.1 on the mi4c and have much better picture quality now, but have to live with a slightly lacking OS - for now.
[Xiaomi Mi 4C] rob rich:
You can do it easily right from your phone. Open dialer app and type *#*#6384#*#* (MIUI) and click on the 3 dots in the upper right corner. Click on Tools and then logs. Choose dmesg. Its saved in the folder debug_log
[Xiaomi Mi 4C] Stevex26:
Just tried and it says 'imx258 probe succeeded'. I wonder if someone has the Samsung sensor..
[Xiaomi Mi 4C] Raon:
Your methods doesnt work with my phone, the dialer method (no Tools option appears) neither the terminal option (i got a 134 pages long log with no mention of imx or ov5670)
[Xiaomi Mi 4C] Rhyn:
You need to pull the dmesg log right after reboot, because it has a fixed buffer and it's rotating the boot messages off from the log after a while.
[Xiaomi Mi 4C] rob rich:
What Rom are you using? Maybe reboot and try again?
[Xiaomi Mi 4C] Raon:
The last MIUI Global rom (22-10)

It's working, imx258 suceed just after reboot, thaks
[Xiaomi Mi 4C] LucaBB:
[MENTION=2493055]Raon[/MENTION] Can you explain how you do it? Because i reboot my phone but doesn't work for me. Miui v 7 5.10.22 dev.

[Xiaomi Mi 4C] rob rich:

[Xiaomi Mi 4C] Raon:
I did the terminal version

Download a terminal app on the play store

allow root for it

reboot

open terminal app and type

su

dmesg | grep -i imx

you should have "imx probe succeded"
[Xiaomi Mi 4C] LucaBB:
I' ve done it yet before. I will try again. Thank you.

Yep, i've done it.

IMX258 probe succeeded. So also my is a Sony sensor.

Inviato dal mio Mi-4c
[Xiaomi Mi 4C] ermacwins:
I hope I don't get a Samsung sensor :/
[Xiaomi Mi 4C] rob rich:
I dont know if its the same Samsung Sensor like in Redmi Note 2, but this thing was really really crap.

But maybe it was a cheaper sensor. I dont think the difference between the two they built in Mi4c is very big. The Sony Sensor is not more than average in low lights/indoors. But maybe its just the Software which is crap.
[Xiaomi Mi 4C] vipercubic:
So my 4C arrived too, i got imx258 (found out in dmesg). But really i wouldn't worry if i had Samsung sensor, it's the same Sensor that Galaxy S5 has so no, it's not crappy at all.

I do agree that low light / indoors sux, and i really believe it's a software issue. Both of the sensors are top notch so they should perform great.

Even I suspect that the stock camera app's settings are at fault with night shots. Blur points to a long (too long) shutter time.

I think that if you manually set a shorter time you'll find decent night quality. I hope Xiaomi will tweak default settings better and set more conservative settings.
[Xiaomi Mi 4C] stillka:
Hi,

I did a tests photo shooting yesterday with Sony and Samsung camera sensors, outdoor and indoor photos looks same (optics is same) but ISO of Sony images was generally lower then Samsung with the same shutter speed (cca 10% difference) so I would say, Sony sensor is slightly better and more sensitive then Samsung.

I can publish some pictures if you want but generally they looks equal....no problem with Samsung sensor at all :)

I found Google Camera searching in Google. For some reason it was not showing in Play store. I can record 4k videos with my Mi4c 2GB/16GB.

Isn't official camera capable of 4k already? It even records 4k@30fps smoothly.
