Trying to Identify Kernel, Possible Overclocking Possibilities for DM7022 Radio

[MurzzZ]

Hello all!
There is the good news from Russia. One of DM7033 owners could made CWM Recovery 5.0.2.7 for DM7033.

Now we have two version of recovery.
v1: nand mounts as "sdcard", sdcsrd mounts as " /sdcard/tflash"
when you make backup from recovery - backup files will be placed to nand
v2: nand mounts as "sdcard", sdcard mounts as "/emcc"
you can make backup to nand or to sd

How to install:
1. put cwm5_hawst.img to sdcard (for example /sdcard/tflash/cwm5_hawst.img)
2. run cmd.exe

adb shell
dd if=/sdcard/tflash/cwm5_hawst.img of=/dev/block/mtdblock7
sync
exit

3. exit from cmd
4. turn off device
5. turn it on with pressed "back" button to enter recovery

Hi Murzzz,

Thanks for the links, The Russian forum is very interesting & it appears that you & our other Russian friends have been just as busy exploring & enjoying the DM7022 / DM7033 as us over here. Its good to have you & dyn620 who can comunicate well in both languages sharing the info.

Hi Ellolo,

Welcome to the thread, First thing I would do is check the contacts interface between the pad & the main unit for damage etc, two rows of brass contacts on the front of the main unit at the bottom & matchng circuit board contacts exposed on the rear of the pad. if that dosent work remove the iso connector block on the back of the main unit, this will disconnect perm live & acc live & enable the main unit to reset, give it a min or two then reconnect, boot up & then try the screen.

Good luck & if I think of any thing else I'll post it on this thread, let us know how you get on.

Hi Mark and all

Thanks for your help.
Contacts seem to be OK. I disconnected the iso connector and also reset the car unit with no effect.
I sent a mail to my reseller (libertyforever) which is in contact with the factory (they asked to check if the pad was fully charged and for a short movie showing the problem).

I'll keep you informed.

Another one good news we now has a firmware for main unit with DBV-T. And we know how to change interface of main unit. TV, Radio, etc.

But I hope we all together can find the way to make it working as we need.

Hello all, I have been reading this thread for the last few days while moding and working with my ES777A, and I am having problems with my GPS, when I first installed the head unit about 2 weeks ago the GPS worked great, worked with google maps and iGo, but now I cannot get a gps fix. I installed GPS Status and GPS Test and used both to reset and update the A-GPS with no luck, both apps report 6-10 sat in view but will not lock on any. I am going on a trip in a few days and need this fixed quick. Thanks for your help.

Update:
I did a reset (reboot with power & back button and wiped all data) and it worked for about 5 min then lost fix and will not get new fix. Here is a pic of what GPS Test shows. I am at a loss of what to do to fix this. BTW I do have root access.

Hi Flytyme69,

One thought occours, another forum member (I think it was TDI_VOTEX) had gps problems & it turned out to a fault with the cable broken but inside not visable from the outside if I remember right. Do you have access to another gps pick up unit to try replacing it ?
Another thought is to ask you if you have placed the gps pic up unit outside your car ? as some have put them inside the dasboard, but they are designed to go outside.

Let us know how you get on.

..., another forum member (I think it was TDI_VOTEX) had gps problems & it turned out to a fault with the cable broken but inside not visable from the outside if I remember right...

Yes it was me, but the fault in my cable was completely shorting the cable and I had no signal at all, not even a sat.

This looks more like a software problem.

Edit: One tough I just had, does the S/N ratio fluctuate a bit or does it look like it is frozen? Some Apps like "Simple NMEA Monitor" enable us to see the NMEA sentence coming from the GPS chip. With it you can diagnose where the message get lost.

Hi Flytyme69,

Have you tried disabling any non essential apps from starting up & then reboot, I' was thinking about tdi_votex had posted & was wondering if another app was interfereing with the gps . I'm no android expert but I have had similar issues on windows based kit.

Good luck.

Hi Guys,

Today my replacement screen assembly arrived, or so I thought ! a well packed package but all I received was the lcd screen, no digitizer & no plastic front film ! I had been very clear describing what I needed & they appeared to understand, so I'm hoping that it was just a honest mistake. Its a bit frustrating but these things happen when different languages are involved, I've emailed the supplier & await their reply.
I was wondering how Ellolo & Flytyme69 were getting on with their problems, hopefully they have got nearer a solution.

Hey guys, thanks for the info, I am going to try them out and post back, I have been away on a family medical issue, thanks for ya'll feedback.

 

[Flytyme69]

Well I couldn't get that to work, downloaded Simple NMea app and it doesn't show anything. Other than gps status, IGO and maps no other app installed... could the root be messing it up, how could a do a full restore, cause when i did the reset it still had root and super user installed.
