USB OTG

Hi genius

I managed to create a proper USB OTG by myself following a guide found on google.

It works smooth and perfect with a nokia E7, so I am sure it has no problems.

Well, here h ttp:/ /youtu.be/ HNxTunh4QvI (please remove spaces in the link) I explain what happens when you plug an OTG cable into the tinji.

"Something" happens, but not what is expected. Looks like the kernel does not support OTG even if it should, according to the theory

stating this device is android 4.0.3

Can anyone here elaborate the kernel so that it supports OTG?

Calling

Hi, i have problem with all of firmwares. Many times it is not possible call with this phone.I must turn to airplane mode and turn it off, after that it is all right.But without any reason after some time i can not call. In this time is my phone inaccessible. Have you any the same problem ? Or have anybody solution?
[General Questions and Answers] superkekko:
I have the same unsolved problem. Most of the times phone calls begin with normal audio qualiti, after a couple of minutes on the other side

they tell me that as soon as I speak a loud noise is heard, as if I am close to some kind of radio device... This problem doesn't exist if you use earphones, so I tried going into engineer menù (dial *#*#1478963#*#* to enter this menu) and setting the same values for headset on normal mode,

but I had no luck.

If anybody has any idea, please share it. This is very annoying :p
[General Questions and Answers] enkoff:
Yes,this problem with noise during call i have too. So main functionality of this phone - calling, is broken. This phone is unusable for it.Please help, i like him :crying:
[General Questions and Answers] superkekko:
I just tried an hack, but failed. Let me explain anyways.

I removed back cover, opened up the device removing the 7 screws on the back and lifted the plastic part that contains antennas and holds battery/sim/sdcard.

I saw then how wifi and gps antennas connect to their eternal extensions, and on the bottom side noticed three pins that I realized - turning

on the device while still open - to be the connectors to the gsm/wcdma antennas.

With some adhesive aluminium tape I managed to cut some thin stripes in order for them to connect separate ways each one from the other,

connected them each one to one antenna's pins so that I had a bigger antenna that could be hidden under the battery once closed.

Result: no signal at all.

Removed everything and put it back together as it was.

The static noise issue during phone calls on this device really fustrates me. It's an overall good device, hope we can fix this somehow.
[General Questions and Answers] mrfrustrated:
no service no signal issue

It has been a few months since I have touched this Tinji phone. I have previous post about having no signal and no reception. The phone recognizes my SIM and I have taken my phone apart and my GSM antenna is properly installed and not loose. Has anyone come up with any solutions? :eek:

Thanks a bunch!
[General Questions and Answers] idoasis:
Thanks!
[General Questions and Answers] superkekko:
Well guys

There's something new I found out regarding both no signal and noises during calls issues.

On the russian website I noticed that the image of the open tinji had something different from mine: infact, there are two connectors for gsm/umts

there, while on my mobile they're split into three.

Taking a closer look to the flat that should be my antenna, the two channels connect.

So what I did was to connect to the two pins (the first on the left and the one right in the middle of the three) to some adhesive aluminium tape...

And it worked: I got a strong signal, and was able to connect to the internet via gprs with no problems, even if my operator network coverage

here in my house s**ks.

This is a good new of course, but doesn't solve the noise problem.

I mumbled and put everything back together then, put my tinji on the table, and called myself on another mobile I have, putting this second mobile next to

the tinji. Replied myself and waited until the static noise began. I noticed then, while my hand was getting closer to the tinji, that the noise

was changing... and you know what? I turned the tinji backside, touch screen facing the bottom, antenna up... and well...

I realized that if you put a finger on the antenna flat THE NOISES COMPLETELY DISAPPEAR.

To prove that you just need to remove back cover (the one that just covers battery/sim/sdcard), no need to unscrew anything.

What we have to do to solve the problem? I think we have to find a way to ground the umts antenna.

I scratched the antenna flat a little bit so that a little copper comes out, and put one side of a cable on that point so that I can find a good

grounding point on the mobile... by now I found some good points only if you use the tinji on a table and don't touch it... for some reason

when I try to use the tinji holding it in my hand it doesn't connect to the internet.

I am also trying to find a good solution to isolate the microfone.

Stay tuned.

[General Questions and Answers] TuoNonno:
I need testers for the noise bug of this phone...

I've made a mod on mine (see attached pics) and till now the noise is vanished. But I've only tried with 5 calls that is not so much to test with.

So please, try it on your mobile, it is not destructive.

You need to disassembly the phone by releasing the 7 screws on the back, then tape the contacts I've rounded in red.

1) On the plastic frame you removed from the phone there are the antennas. The bottom is the gsm/wcdma antenna. Tape the pin as the photo.

2) Mic: after you remove the plastic with antennas you will have a piece of pbc where the mic is soldered in, gently slide that piece out of the metallic frame (help yourself by removing the 3 screws and disengage the antenna cable) and place a piece of tape like the photo.
[General Questions and Answers] superkekko:
Very good. I did something similar, but way much more invasive: I insulated with tape the microphone (not as you did but almost) AND eliminated stock antenna on the bottom (the one right on top of the mic), connected to the three pins some IDE cable cuts, let them pass under that piece of plastic containing the speaker, applying a little hole on the battery frame and let the cable out while putting everything back together.

Also, I removed an antenna flat from an old nokia 6630, cleaned it up and fixed the other side of the IDE cable to the copper of nokia's antenna with insulating tape. Now whenever I shift batteries I have this pretty ridiculous vintage-looking antenna, but it stays good on the back of the battery in between with the cover... and the signal strenght is much better than before. My theory is that 1) the antenna must be as far as possible from the mic; 2) Nokia copper quality is way much better than the one you may find in a cheap chinese smartphone.

Sorry but at the moment I can not post images of the mod I did, but I promise I will post them asap.

Regarding lost signal/no service, or the mobile stating you have service while you don't really do, I guess we all here have the same bug as many 4.0.4 android devices. There is plenty of galaxy nexus and note out there with ics 4.0.4. that lose 2/3g signal as soon as the device goes in stand-by mode (or deep sleep).

There is no cure for that yet: if you rooted your tinji and set setcpu max to 1000mhz and minimum to 750mhz, I am sure you found out that screen flickering has gone. I read here and there (also on google code) that this trick should work for the same problem on previously mentioned devices, but not for my tinji.

Oh, one more thing: I am using Tinji_i9300_deodexed_by_knski_2.zip rom at the moment. It has the feature to reboot in recovery mode,

that's pretty useful.

Has anybody here tested the rom too? Do you think something better is out there? Please advice in the case.

Opening my device to fight with the antenna I found a stiker reporting H640_77F0v01.01b05 inside, by the camera flash.

I read that knski_2 rom is based on H640_77F0v01.01b03

...anyone here has a backup of original H640_77F0v01.01b05 rom? if yes I am sorry but didn't manage to find it here in the thread.

Does it implement a custom recovery? Could you add to the shutdown menu a "reboot to recovery" selection

Rooted, reflashed, much improved i9300 but lost GPRS ((& GPS is still pants))

I have rooted my i9300 & reflashed with N2k1 stock rom H640_77v01.01b06.

All is fine with the exception of lost GPRS functionality. I don't know the exact cause of this as I have been messing about with every aspect of my phone.

I have googled "lost GPRS" and trawled xda and really I don't know where to start to interrogate my settings and/or check connections (I've had the back off the thing several times for GPS antenna messing about, mic interference improvements etc).

Any help & advice on what I can check to get my GPRS up-and-running would be greatly appreciated.

[General Questions and Answers] mitchw1971:
Getting the back off

Once u have removed all the screws u still have to disengage the several plastic clip features from the phone back cover and the painted surround bezel. Use a small flat screwdriver and carefully push in the back cover next to each clip to disengage. If u do this along one side of the phone plus the clips at the top & bottom u can gently ease the cover upwards and off. Also be sure both ur SIMs and sd card are out of the phone- this would also stop the cover disengaging.

Bad luck

Hi guys

I had bad luck while opening the device last time.

One of the two wifi antenna pins on motherboard came off, the one on the bottom.

I still have the small little piece.

I see no copper contact on the motherboard and have no idea about how to put the piece back in its place.

Do you have any suggestion?

Scratched a bit on the side, managed to see where the contact was and soldered.
[General Questions and Answers] mitchw1971:
Hi- I made the same mistake- only that I broke off the top one of the two GPS connectors on the board. I fixed it and, although I cant believe my bodged attempt worked, it did. So forgive me for my crude methods but here it is:

U will need:

1. The broken off spring pin or another pin stolen form another phone

2. Some aluminium kitchen foil

3. Some sticky tape

4. A sharp craft-knife

5. A toothpick

6. A lot of patience

7. Any children and partners u may have well out of the way

i) Start by taking the knife and carefully scraping the area next to the broken off pin- u should be able to reveal the tiniest bit of copper on the board that connected the pin. ii) get a bit of kitchen foil and make a small 1mm x 2mm pad by folding it over one or two times- use the knife here to help u. iii) Place the foil pad over the bit of copper on the board and ensure it touches no adjacent metal parts- use the tip of the knife for positioning. iv) Get the broken pin and sit it on top of the foil in the same position that it originally held. v) get a small bit of sticky tape and place it carefully over the foil (not on top of the pin obviously) and try to secure the foil to the board so as to stabilise the whole thing vi) another small bit of tape to hold the pin to the board (I was able to do this without covering the top part of the pin so as not to disrupt the connection thro to the antenna). vii) Break off the tip of a toothpick (about 6mm length) and place it on top of the tape thats holding the foil to the board- lay it length-ways- this will allow the back cover (when screwed in place) to push down on the whole toothpick-tape-foil-copper stack making sure u have a good contact. iix) reassemble ur phone and test it using "GPS Test" (app store).

I understand this sounds like madness- but it worked for me- I would take a photo but I dare not open up my back cover any more (Its working and I'm leaving it well alone). After doing this successfully I'm considering neurosurgery as a career move!

So desperate

Yesterday I rooted my cell phone with the Root_with_Restore_by_Bin4ry_v17.zip version, and then I downloaded the Root Uninstaller app to uninstall those freaking Chinese applications. Everything seemed fine.

I got home and I ended up uninstalling the Samsung App (also in Chinese), turned the phone off to try an SD card on it and that’s when the nightmare began.

When I turned it back on…

1.	The display began to flicker and I could do nothing. Finally, I could reboot it and…

2.	The SIM card, even though it detects the Vodafone network, does not let me make calls. When I try, the following message comes up: ‘The contacts application has been stopped’.

3.	Every time I try to download an app from Play Store, there it goes again: the display goes mad flicking again.

Well, I am quite desperate for help and I haven’t found any threads from people with a similar problem.

Any help would be appreciated. Thanks!

Hi

Search in this thread the necessary instructions to flash tinji rom with SP tools.

First you need the drivers on your pc, and I guess you already have them if you rooted your tinji.

Then figure out the rom to flash into your device with SP Flash tools.

The rom I am using is the facrory's last one (b06), changed recovery.img, boot img and system img with the ones got from other roms.

I suggest for you to begin knsky_2 rom.

Search the thread to understand what I am talking about.

Network - Put sim card in GSM slot

Hi guys

Me and my friend (he also owns a tinji i9300) agree that if you only use one sim card, and put it in the GSM slot, you can get the phone to work with no network problems.

No more problems with calls then, neither internet connection.

Suggestion: download from market "Set DNS" and set mobile connection DNS to OpenDNS.

Looks like SIM slot 2 has priority over antenna IF two sim cards are in.

Let me know if you try this.
