Hi. I have I have a Daxian G20.It has android 4.0.How do I root it? And how to instal cyanogenmod in it? What is the version for my device?
[General Questions and Answers] hobbista:
Hello everyone :)

I have same problem.

Under Settings -> About phone I have:

When boot with holding vol.up, vol.down and power buttons show me Factory mode with this options:

When i go to "Version" show me:

Now I'm looking for the next steps :)

Thanks in advance
[General Questions and Answers] OpenMinded:
If you boot in engineering mode, which is by holding volume down, you can see it is running Android 2.3.6 .

Ssearch XDA for Daxian G20 and see the root agony.

If you can root this, please let me know.

The problem with it is that it is not flashable, because it seems to shut down the com port.

There are some forums discussing there are points to solder, I did not find them after peeling my sticker under the battery.

Please let me know if you pull it off to root it :)
[General Questions and Answers] hobbista:
Unfortunrtly, I can't root this phone (yet :D ). I'm newbie in Android world, so I'm still learning.

I made scatter file, but phone cant connect when is turned off.

Actually, it connect with PC, and appears in device manager (under Ports) for 3-4 seconds, and then disconnect :(

Tried with Win 7 (64) and Win XP (32), but nothing... completely same thing.

There are no points to solder (under the sticker), but i found some contacts. There's a place for 3 pins, but one on the right side is empty hole (red circle on the picture).

h.ttp://postimage.org/image/lhmrbji47/ (delte dot between h and ttp)

I hope that first one, who root this phone, will let us know :)
[General Questions and Answers] OpenMinded:
There are two options that I know of that might work:

1. You are able to somehow create a properly signed update.zip with a patched recovery or boot img with root files

2. You find the connection points on the phone that need to be connected to boot in proper flash mode.

I tried all other stuff I could find to no avail.

china-phone.ru forums have some posts about those points. not for our phone, but for similar ones.

I hope you will pull it off. please post if you do :).
[General Questions and Answers] OpenMinded:
Ok, I managed to find the two points that need to be connected for the Daxian G20.

You need to open up the phone, it is under the small round battery. The two at the upper left.

I was then able to flash recovery.

tough luck and a bit of stupidity : i have no backup.

Took a chance by flashing the recovery and boor.img of another phone.

It is not a brick yet, but I need the original firmware.

Can anyone who was able to make this mod too please dump it?

I might be able to fix a modded recovery then and if someone knows how, sign it properly.

cheers

---------- Post added at 07:36 PM ---------- Previous post was at 07:20 PM ----------

I managed to get flash access, but was so stupid to try another recovery and boot.img.

So don't do that!

You can get dump and flash access by opening up the phone, and connect the two left of 6 points under de small round battery in the top.

there is tx1 or something and ground.

Then use SP tool 3.224 or something and your pc will find another com port, which will allow flashing.

But: dump the recovery and all other partitions firtst!

If you get this far. please dump boot.img and recovery.img .

Then I can get my phone running and I will try patching the recovery.img.

Or if you succeed, please post patched recovery and boot.img :)

thanks
[General Questions and Answers] hobbista:
Unfortunately, these days I do not have much time, but, you do a great job :good:

Just to confirm: I have to connect this two points (red arrows on the picture)?

h.ttp://postimage.org/image/5rdxqulvf/

And, my scatter.txt is:

Edit: I did not read carefully - now I'm confused: Which "two left of 6 points" ?
[General Questions and Answers] OpenMinded:
Hi,

Awesome that you have this phone too :).

I am pretty surprised, you do not seem to have the points.

Do you have the Daxian G20(+) ?

The point you circled are much smaller.

They are 6 grouped like : : : that.

They are a few millimeters and they are right under the round battery that is still visible on your picture just next to what you marked.

Can you try and peel off that battery and look under it?

Be carefull for the wires, but it is very doable by putting a screw driver just around the sides gently, or better some small plastic thing to avoid short circuit.

Please let me know if they are there :).

good luck!

update: scatter file looks similar as mine. same address for recovery.

Man I hope you succeed and are able to make a dump :).

I found only 1 russian guy that has it rooted, but he has not responded to my request.
[General Questions and Answers] hobbista:
My phone is just Daxian G20 (without +)

I found it, as you said, under the small round battery (I used wooden toothpicks) :)

h.ttp://postimage.org/image/9wxif67b5/

My soldering iron is 60W so I must found another way to make connection :(

And, I did not see Tx1

Till now, I was followed tutorial (h.ttp://w.ww.mediafire.com/view/?8mxvy0ey5yfdu59), which i found here (on this forum),

untill scater.txt. If I make this work, i should make read back for bootimg and recovery.img, and send this files to you?

I mean, until this step is safe for now?

As I said, I am newbie in Android world :)
[General Questions and Answers] OpenMinded:
Great! It is the two left most of the six pins that need to be connected.

You could either use a pencil, or some silver paper, just be carefull with other connections :).

I soldered two wires on it, because you need to disconnected the points to be able to boot the phone.

Maybe it is not tx1 but something similar :).

The other point is ground, so it has quite a large copper plate probably.

I just held the soldering iron quite a bit longer and used some flux and I was able to get it soldered.

Not sure about how many watt that thing was, but maybe more then yours; you can just give it a try.

Or maybe pencil is the easiest :).

You would really make me very happy if you can read back those files indeed :).

I'll just flash them and see if my phone boots :).

All steps are pretty safe, just make sure you do not write to any of the partitions untill you have a proper backup.

Once those points are connected it should be easy, I do believe you still need the battery attached, mine loses connection other wise.

I am the perfect test case for the recovery.img and boot.img.

Once those work and my phone boots I will make a full backup as well (if I read how :) ).

Then we can try to start rooting :)!

I attached a picture with the points marked to connect.

I am eagerly awaiting those dumps :).
[General Questions and Answers] OpenMinded:
small addition : writing is being done by the download button : so do not be misled :).

It will actually flash the phone.

You need the readback option.

This two points (pins) are GND and something like TXD1

h.ttp://postimage.org/image/prp6yf8f1/

h.ttp://postimage.org/image/8pf19306j/

When I was connected this two pins and attach USB cable, Win7 was install new driver - Android USB ethernet/RNDIS.

h.ttp://postimage.org/image/w4ftp0vaz/

Same is with or without battery. Read back did not start :(

Without this two pins connected, apears MediaTek PreLoader just for few seconds :(

h.ttp://postimage.org/image/wjg2knecd/
[General Questions and Answers] OpenMinded:
Good! almost there :).

When the pins are connected, you should also see a com port.

Perhaps you need to reinstall the drivers?

There are drivers for different modes, you need them all.

For me I needed the battery to be connected to get the port to stick.

So procedure: connect usb cable to phone, not pc - press read mode on sp tools - connect battery - connect usb cable to pc .

I also use Windows XP, because it gives you a lot less headache, especially in terms of com ports.

Make sure you enabled all rights and removed all restrictions.

Be careful with virusscanners, the usually demolish the flash tools and exploit tools.

If you need any help, just post :).
[General Questions and Answers] hobbista:
This is strange - when i connect pins, i can't see COM port :(

And driver install itself without battery (Android USB ethernet/RNDIS).

When I put the battery, nothing changes - COM port does not appear !?

Tomorrow i will solder wires on this pins, and try again with XP.

You've already helped a lot, and I hope that we will make both phones rooted :good:
[General Questions and Answers] OpenMinded:
mmm, that is strange. Perhaps you need to deinstall that driver? by heart, you need MTK 6575 serial port driver, and two more.

Without battery, for my phone I keeps seeing a com port coming and disappearing in XP.

When I connect the battery, the com port (com10) keeps being visible.

Without connecting the points, I only see another com port, com 7.

Do you first connect the battery and then the usb cable?

Not sure if it matters, but that's what I do.

You also helped a lot, also other people who will read this when they bought this hard-to-root phone :).

Ok, good luck, I will keep an eye on my email for updates :)
[General Questions and Answers] OpenMinded:
I attached the drivers for your convenience.

I would deinstall the NDIS one if you see it.

then install those files, also the mtk one.

I am able to boot in to recovery now, but booting the phone or booting engineering mode does not work.

Can you post your full scatter file and perhaps dump the full rom you are running?

Would be awesome! Don't forget to remove your personal stuff.

I am fiddling now and looking for Android Kitchen tools to try and mod the recovery :).

Thanks a bunch!
[General Questions and Answers] OpenMinded:
i made a cwm that boots.

it's attached.

I cannot mount my SD card and stuff, so not sure if i need another cwm base.

You can try it if you want.

Just make sure you only flash recovery!

Then you can always go back to the original.

When this works, you can flash a root.zip and you should have root.

My wire is loose now, so I am off soldering ...

[update] : please wait, seems like an issue in the recovery.

I just reflashed original which does read sd.

I am off working and hoping you can dump that rom :)

[update2]

Ok! The recovery attached now should be able to flash unsigned stuff :).

You need up/down and power to operate.

Pretty cool :).

Now I can root my phone, it just does not boot :(.

There might be an issue with that boot.img.

It would be great to se the full dump, hopefully my phone will boot again...

I followed the instructions of the yuweng (h.ttp://www.mediafire.com/view/?8mxvy0ey5yfdu59) and made a new recovery.img - but i didn't try yet :)
[General Questions and Answers] OpenMinded:
Hi, I do not know exactly how to fully dump it, but if you do it in the same way for all other partitions it should be alright.

My current guess is, is that something is wrong with the boot.img, because recovery works fine and the should have a similar or exact same kernel.

Thanks for the files, awaiting the dump :)!!
[General Questions and Answers] hobbista:
I will make boot.img again :) Maybe the name should be bootimg.img, because the name of the file is bootimg?

And, all other files should make like .img files?
[General Questions and Answers] OpenMinded:
Hi,

it's called boot.img. Filename should not matter, some bits and bytes are flashed.

Did you try my recovery? should work :).

I'd be very happy happy if you can dump the others parts in the same way, yes.

Funny thing is using your scatter file flashing does not work for me, only with the one I used from the candy phone I found.

Well, let's hope it will work again :).

thanks a lot!
[General Questions and Answers] hobbista:
OK, just asking ;)

I didn't try your recovery.img because it will be disaster to make both phones unusable.

First I want to try to fix your phone :)

Unfortunately, I can't start now to create .img files, but I think that those files be ready in approximately 2 hours.
[General Questions and Answers] OpenMinded:
Awesome! I'll wait :).

Flashing recovery should be safe and you can go back to the previous one.

You would not need to flash any other partition.

I was just stupid to flash boot :(.

Can you redump boot.img (instead perhaps reuse the existing)?

Agreed it is safer to have mine working again :).

Thanks again!
[General Questions and Answers] hobbista:
Take a look at this picture (now I can post images directly :) )

Check again addresses and lengths. This warning message appear for last file only (spare.img)

Dump will be here soon :)

PS. Please do not constantly give thanks because we're here to help each other :good:

EDIT: I changed size of "spare" file from 00A3FFFF to 00A40000 - this is the oly way to make spare.img

Wish you luck!
[General Questions and Answers] OpenMinded:
Well let's hope that that is not important :).

I actually hope boot.img is the issue and that flashing that fixes it.

On the other hand you rom may be different i just might need the belonging partitions, but then I would expect a longer boot process.

I'd like to thank people when they are helpfull and you just really are.

Keep up the good work :).

I can't wait to get it working !

[General Questions and Answers] OpenMinded:
darn Darn DARN!

I was about to post succes: just flashed bootimg.img and it was working again!

Then booted to recovery i have made, flashed some zip I thought contained root and it hung.

Thought I messed up boot, so reflashed, still hang (like I had all the time).

then when flashing I got an error that the bootloader is not found.

I tried your dumped dsp_bl.img but it does not want to load it!

I can load the one from the Candy phone, flashed it, black screen.

Can you try and redump just dsp_bl.img?

I am pretty sure my flash memory is about to be f**cked and then I have a brick.

Then I can send you mine for spare parts :(.

Wish I had kept it running (but that was without root :( ).

---------- Post added at 11:30 PM ---------- Previous post was at 11:15 PM ----------

[update]

So i can still flash the dsp_bl. it just seems your dump is larger then the one i used instead.

i just get a load error. will try if a rename helps :).

[update2]

a rename is no solutions.

I hope you will be able to get a proper one.

Apologies for the inconvenience !

---------- Post added at 11:48 PM ---------- Previous post was at 11:30 PM ----------

another add: there is an option that says ECC check in the SP tool.

Can you please use that?

should check for errors.

in the mean time I tried cutting text from the boatloader file to no avail.

I keep getting the error.

Maybe we need some way to find out how to dump it properly.

Sigh...

i'm off to bed soon. need some sleep :(
[General Questions and Answers] hobbista:
:(

I was impatient (stupid) and I try to put recovery.img in my phone.Unfortunately it went wrong

And then i try to readback .img for you, but...

Phone still works, but without sound :D

EDIT: I boot in engineering mode (vol.up+vol.down+pwr) and clear flash. Now the phone is working again :) Tomorrow i will make dsp_bl.img with ECC check :)
[General Questions and Answers] OpenMinded:
hi,

that sucks!

Just take 1 advice: do not flash too many times :).

You can try the recovery I posted, it worked for me.

Just not sure about the flashing, because I read you need to use the proper CWM for the job.

It is also possible that it messed up my phone.

Only try it when you have a complete dump and you are willing to sacrifice the device!

Double check when flashing that the wires are properly connected, perhaps reboot the crappy windows.

I was able to create a flashable boot loader, I looked at the candy one and cut the same size of your dump and then it went ok.

But all I have is a black screen now!

I was trying to flash preload, but I do not see how.

It's pretty weird, with a bootloader selected flashing still happens, but no more booting for me I am afraid.

I am unable to get the preloader working to flash, and I am affraid if I flash that improperly, I cannot flash any more.

I will probably just try it because I have no other option :).

---------- Post added at 12:50 AM ---------- Previous post was at 12:13 AM ----------

Well, you would not believe it, but it is back to being undead like before.

I was able to use preloader from the candy, my modded bootloader en de uboot and boot imgs you posted.

Now I have working flashing, recovery and battery load screen :).

Then I flashed every part seperately, I found out my suspicions were true: flashing sc_ro.img fails at 98% , android.img at 99%.

I tried a format to no avail: the flash is just dead there.

So unless there is a way to tell the phone tot not use that part of flash, it is a nice CWM flash device that does not boot normally.

I think there should be a way, but I do not know for sure where the mappings are being done, I think it is in the preloader.

So the approach would be:

- open preloader in hex editor

- look for know adresses from partitions

- determine exact broken part of NAND

- mod preloader to work around bad NAND parts

- mod img files to fit modded preload partitions

- think about other place that may use the bad parts

Man, if I pull that off some how, I'll put the phone for sale for the highest bidder, starting from 1 euro with the nice story included :).
