overclocked kernel is here

[yerzu]

you sir
get the award for "most clueless person talking out there bum"
first: its called a COLD JOINT
second: if cold joint was the problem you would have worse issues then apps randomly exiting
no display,random full reboots,hard-locks,display corruption
you how ever would not see a app crashing as the sole effect
any of the apps for these devices simply do not work regardless of the state of the hardware

third: anyone that attempts to bend there device thinking it will have some kind of effect will most likely have a dead device

Forth: the main issue that causes stability problems is the power supply and or the USB cable you are using attempting to flex the device is just gonna make it worse

Finally: if there is a problem with the BGA on these chips putting pressure on it isn't gonna do shit you would need to heat it to at least 350F with a heat gun to reflow the solder or a trip though the oven at 370F for 5 or 10m

~I do bga repair for a living and these problems in my experience are not related to a cold solder joint or bad BGA job

Sorry, english isn't my main language. I make bga repairs too and stability problem is a first sign cold solder joint man. Most of all I repair graphic cards and like here first of all - game quits when unit loads or wee can see "artifacts". In my case was a one pixel size blue dotts on the screen (I saw this only if I been close to tv) and antutu quits when I start test. I heated up rockchip and now all gone man! And my PSU is good quality 4A 5V.

You are a BGA expert and Your advise is using oven... OMG...

[humpty_dumpty_empty]

OUR STICKS HAVE BAD SOLDERING MATERIALS, IF YOUR DEVICE MOMENTARILY EXITS FROM APPS (f.e. mxplayer antutu) PROBABLY YOU HAVE BAD ROCKCHIP SOLDERING AND YOU CAN TRY WARM IT UP - HOTAIR WITH GOOD SMD FLUX!

haha lol...that was blowing!! be it cold solder or bad solder, my wifi and OTG are no more working now..not sure what the issue is .. I for now have rooted with company rooted rom as other kernels are still not working on my device.. .. I did solder the broken wifi wire back to the antenna and checked if its live...yes the wifi solder looks ok but no wifi connectivity.

Tried modifying the wifi config files but in vain.. ..request your help on how to have wifi and OTG working.. I did go through suggestios/solutions from other posts but none of them have worked.. Any tips for a noob like me please.. thank you.

oven is the better alternative to letting someone that doesn't have a clue lose with a heatgun or for people that don't wanna spend >3k for a IR Reflow bench
the best you can do without a BGA rework station OR a good heatgun is the kitchen oven set at 350-375F for 5 to 15M depending on the application
ACTUALLY removing the chip and re-balling it requires A either a HOT-AIR or Inferred BGA station with the proper templates to reball and flow the solder

PS:
your post amounts to a random guess based on 1/4 of a Clue and full of more holes then a block of swiss cheese, wasn't even close to the mark and probably based on something you read on Google, and whats worse you recommended it to other users as if it was indisputable fact

PSS: giant red font is annoying especially considering that you are Dead-Wrong

back on topic: ill have a proper guide to doing a cooling mod by Weds

No no oven isn't alternative this is horrible solution like a nightmare!

Probably You are much more experienced with BGA - I'm not a repair specialist but FYI on google You can find only oven solution

You are a bull? Red font may warn people who oc sticks, because this is result of that. And I wrote that to anybody who wanna repair it with hotair - do it at Your own risk. Somebody do it yourself, other may go to You with this problem regards!

Re: overclocked kernel is here

To close this issue, apps randomly closing has absolutely nothing to do with soldered connections. As has been suggested, the system wouldn't come to full boot unless the onboard hardware was functional and connected properly. Just as a faulty battery isn't to blame for car power door locks going haywire, Antutu closing probably has far more to do with wrinkles in the hardware / software layer in some sticks, rather than factory defects. Antutu isnt designed with ALL hacked android OS tests in mind. Any benchmark app pushes the corresponding device to its limits and records top end thresholds. They are coded with a set of very specific instructions to fully and safely mesh with a device and test its limits. Inconsistencies detected between hardware & software layers and the benchmark app will end in device shutdown to stop serious errors or damage from occurring.

patch tool 1.7 "load firmware fail"

howdy peeps!

first post and im a noob....

iv got the mk802IV yesterday and noticed the usual issues,so read through rikomagic forum and eventually ended up here, so after a ton of threads i read i think i have this right...! i am attempting to run the neomode's custom rom and sam123's overclocked kernel this should give me the optimum available for now. i gotten as far as to load the MK802_IV_NEOTVCR_V1_20130620.zip to the device and have patch tool 1.7 open with a green icon on the devices connected, but when i try put the 1080p kernel in the FW path it throws up an error message "load firmware failed"

i do apologies for jumping in here as i can see there is some serious modding beging worked out, i didn't just bang up this post with out reading through the thread first. i did see a similar issue on the bottom page 6 but there was no solution posted and the poster seemed to have resolved in their next post...!

cheers in advance for the support and looking forward to enjoying the new roms and kernel's.....

[neomode]

Hello,

First let me know what Version of MK802IV you got.
For this check your Serial Number on the Back of your Device.

- 201307 means New Wifi Version

Lower than that it is the old Version.

Neomode

[smith4130]

cheers neomode

20130500802.

old version, but wifi seems to be fine.

[neomode]

OK so you have the old Version. Download my CROM for the Old Version and Replace my Kernel with the Kernel from Sam321 and then Flash it.
This should Work for you.

Neomode

[smith4130]

ok downloaded the zip from www.freak-tab.de/neomode/MK802_IV_NEOTVCR_V1_20130620 unpacked it and removed the kernel file from the image folder and replaced it with the 1.7ghz ram 800 kernel, then i run the ROM flash tool v3.17 that was in the pack, the first box is green and "founder Rkandroid loader rock usb" flashing, but prompts "kenelfile not existed" when run.

edited: i started over again, unpacked just your rom and kept your kernel and it flashed with out any issues...

[neomode]

The Name for the Kernel must be "kernel.img" if not you get your Failure.
Please check it.

Neomode

thank Sir and a donation is on its way......

trust webcam on s400 ?

I buyed a cozyswan s400 with 4.2.2. How can i install my trust webcam usb ? Is there a firmware for this ?Thanks

[neomode]

You cannot use every Webcam in Android. The Webcam must Support the UVC Standart.
This is not supported by all Webcam´s.
The best Supported Webcams, are from Logitech.
