Hi Guys,
As usual other guys, I screwed up my Canvas HD 116 (hw version 1 and sw version 16) by loading JB 4.2 and got TP firmware upgrade error. And then I started work on getting touch panel (FT5206) firmware working.
Well did adb on factory mode and tried running Tpupgrade using OTG keyboard, and got Firmware bin file error. So I looked up /system/bin/factory bin carefully and found out that it searches touch panel firmware in "/mnt/sdcard/tp_firmware".
Here is list of bin files it looks under "tp_firmware"
tinno-fts-update-byd.bin
tinno-fts-update-truly.bin
tinno-fts-update-nanbo.bin
tinno-fts-update-baoming.bin
tinno-fts-update-jiemian.bin
tinno-fts-update-yeji.bin
Now I really don't know which Tinno platform 116 has, byd or truly or yeji.....
I got two firmware bin under "/etc/firmware/ft5206" -
tinno-fts-update-jiemian.bin
tinno-fts-update-yeji.bin
So I copied these bin to "/mnt/sdcard/tp_firmware", given 0777 permission (please use 'su') and tried TP upgrade again, but still same error.
So conclusion is -
1. Either I need to find out other missing bin
2. Or I need to fix permission issue if any
well, I am trying hard, if anyone has any clue, info please let me know.
let's work together and get rid of this stupid touch panel firmware upgrade issue.
mmx service center simply replacing all v16 motherboards by v20 motherboards and loading JB 4.2 on it. But I want mu v16 motherboard fully working with touch, so sure, I will try hard to get it
Thanks,
Shrikrishna B
Dude whts this v16 and v20 motherboard? How can we find it?

Just remove battery and below that you will find hw and sw version.
hw version 1 and sw version 12
or
hw version 1 and sw version 16
or
hw version 1 and sw version 20
Now, what I found and predicting is that version 12 and 16 doesn't work with JB 4.2, as touch issue is there as what I found. need to make it confirm from others too.
Micromax has Tinno Mobile platform, and version 12, 16 and 20 corresponds to software versions of this Tinno Platform (TP).
Now in my case, I have version 16 A116, and stucked with TP issue. I am trying to re-program TP firmware bin from factory mode, but no luck yet. There is permission issue for /mnt/sdcard/tp_firmware, need to make it -rw-r--r--
I think ver 12 ,16 ,20 doesnt have much to do with tp upgrade as all these versions were of jellybean 4.1.2 tp upgrade happens when you upgrade to 4.2.1 jellybean that also happens only once .
If you can go to recovery mode you will find an option called tp upgrade select that option by pressing the list soft key at the lower left corner
Thank me if i helped you

In factory mode, sure there is option for TP upgrade, but here are the issues for that -
1. As touch panel is not working, we cant select the option as it requires pressing left soft key. (and hence poor software design)
2. We can launch TP upgrade using OTG keyboard, it starts, but throws error for FW bin file. Ultimately I found that it looks for binary in /mnt/sdcard/tp_firmware folder, but it dont have access rights, and I can't provide it as there is permission provided to do that.

So you're saying to flash 4.1.2 firmware based on v20 first and then flash 4.2 firmware? I checked the development section and that's what I think I should do..
Did it.
First upgraded to v20 firmware, got tp update there. Then flashed 4.2 firmware. Success!
It didn't do tp update during this second flash.
No problems with the update. Touchscreen working, IMEI intact etc etc.. Thanks a lot!
Is there any manual process to update this touch panel after updating to 4.2.1
Like flashing a zip or some else manual process in which we don't to format the user data!!

Well, it depends upon at what place last firmware upgrade failed.
If last time, the TP upgrade failed before erasing out original firmware, then on rebooting phone TP upgrade will again try to upgrade the firmware. The TP upgrade module on boot-up verifies firmware versions in touch panel chip-set with existing one, and upgrades it.
Now in other case, if last time TP upgrade failed after erasing out origional firmware and before burning new firmware, then you screwed up the touch panel. As on next reboot, as there is no firmware in touch panel chip-set, TP upgrade simply fails as it is unable to get touch panel vendor and firmware version.
I am struggling and debugging to get it working, just downloaded source code for micromax a116, so will try to build driver and to get it resolved.

Actually I would like you to know that this thing TP upgrade didn't took place when i updated my phone from 4.1.2 to 4.2.1
and as well the upgrade didn't failed.
It completed in first time.
The only thing I find is some sort of dots on the screen on colored lines of system.
and the screen is a bit laggy compared to 4.1.2
Very poorly written driver for touch-panel FT5316 on Canvas HD A116. Working on making changes in this driver to upgrade touch panel firmware automatically when TP upgrade fails. This will happen at booting time only, so will solve issue for touch panel not working after TP upgrade failed.
Testing the driver on my A116, will release soon so that other can use it.

hey same happened here with a friends device , did u completed writing driver with source code and to rectify the touch panel thinggie to wort flawless , or what to do now? Flash with v20 4.1.2 and the upgrade to TP once more and then update to 4.2.1
TP Upgrade failed.
Was upgrading from 4.1.2 to 4.2.1 but got this TP upgrade thing. I pressed the 'Ok' button one time and it made the touch to stop working. After a reboot the phone just gets stuck on new setup screen. I have given the phone to Micromax service center but since 2 weeks they have been giving me stories about the Touch being damaged on the phone. I was wondering if that IS POSSIBLE?? for the touch screen itself to be damaged just by the touch of a wrong button??
I hope someone does find a solution for this as I have lost hope in Micromax aftersales services.
TP Upgrade failed
If TP update is messed up there is no fix for it yet !! I have spent 3 days and 3 nights trying to get it fixed but my work was in vain. People facing this problem has to contact Micromax service center. I will be visiting them tomo. Once I get the phone fixed may be i can try to find out a solution. Good Luck guys !!:good:

Hi everyone,
I believe there might be a solution for TP upgrade failure. If anybody has a back up of their canvas HD touch calibration taken through Maui Meta I guess it can be restored back in the phone which has failed TP upgrade. Or if some one has a perfectly working canvas HD a back up of touch calibration can be taken and the back up can be restored back in the phone which has failed TP upgrade. No guarantee if its gonna work as its not tested. Good luck guys. :good: :fingers-crossed:

I faced this issue on my friends phone but after several restarts mainly 3 or 4 by removing battery and putting it back did the job. As on 1st boot TP Upgrade fails then taken out battery wait a min and put it back in and start the phone don't touch anything till 10min. to half and hour. hope you get it back working.

I had been to the service center in Bangalore Jaynagar, I dont think the service center guys are trained !!! They wanted me to change the whole Touch Panel which would cost me around 2.5K i tried explaining them it is due to the TP software but I dont think they understood. I am left with no options now.

I currently run my HTC on 3 uk and dowloaded my firmware so that I can upgrade it!!
However when I completed the downgrade my Orientation is no longer working when I turn the phone. tried to re-calibrate it etc but to no avail. Has anybody got any answers on this to help me out please?
Firmware is 1.5
Build number is 2.73.405.5
Regards Ray
Sorry I meant to ask is Firmware 1.5 the latest officially from HTC?
It may be a bug in that version, to be honest if you're going to flash a new rom you probably won't have to worry about this. Worst case you flash back to the original rom which came on your phone and send it back if it's still not working.
I would carry on putting a custom rom on your phone. It will probably fix it.
did you try to wipe the rotate settings ? It's in recent recovery roms under wipe menu ...
Yes, I did wipe it when I added the 1st ROM onto my new phone. I wiped it again this morning to try to recover it. Is there anywy I can restore it?
Just to let you know the orientation is now working again after downloading NeOroM 1.2 and its update. The version is excellent and works perfect like my daughters HTC Desire 2.1 officail firmware. I think its the best youre going to get near to it until HTC releasse the official version.
Thanks again for all your help guyz !!
Hy guys
I'm new to Android and 2 months ago i bought a new phone (S G S II) with Android 2.3.6.
I decided it's time to upgrade and i did it with odin, folowing youtube video guide i instaled Android 4.0.3 with i think a new Kernel as well 3.0.15-I9100xxlph-cl118559.
Now with this update i have a problem with my location, everything that uses this facility it doesn't work (location,gps,facebook check in) and so on.Don't get me wrong at first with 2.3.6 they all worked after the upgrade they simply stoped.
What would realy help me is a sugestion of a kernel,ROM and a version of Android 4 (.0.1/2/3/4) that would fully work and indications on how to install them.
I thank you guys in advance and keep up the good work :good:

Download the latest stock firmware using CheckFus entering data for your phone and location. Flash this firmware with ODIN as you already did. Using CheckFus should make sure you get the correct firmware.
This will not lock my phone on the specific carrier (orange) right?
Lock to a carrier? No, not by just flashing a stock firmware.
And after i download the firmware that checkfus says is the last one how to i operate with odin?
Can you please tell me the steps i have to go trough? because last time i saw a video and i did exactly like there so i don't know on my onw.

There are many threads here that tell you how to use Odin, one of which is by Intratech. These threads will help you flashing the firmware you downloaded with CheckFus. Just read them carefully and follow the instructions. Videos are nice but in the end a written text is much better, belief me, it is worth the time of reading
Well i did as you said and it worked,finaly i can enjoy my phone fully and i discovered i have NFC
Thanks for everything
Hi all,
I have Micromax canvas HD A116, rooted and have used several Custom ROM in it.
Yesterday Evening I installed another custom rom (third in one week) Samflare V 6.3 (No offence, I like Samflare very much and planed to use the same after repair if it is not the cause of issue).
Everything worked fine as it meant to be when i got to bed.
But today morning (first time I saw the mobile) the Touch and Capacitive buttons didn't responded, so i searched some threats and the answer I got was it was a hardware failiure. The same was confirmed by Micromax service center .
My Question is
Is it possible for a Custom Rom to damage Digitizer? (after installation everything worked fine)
or is it a coincidence?
The reason I asked this question is I cant live without Custom ROM
Please help me with an answer...
Thanks in advance

As far as digitizer of A116 is concerned it may get partially stop working if you have installed Custom Rom on 4.1.2 (not 4.2.1) directly. It is recommended that you get your phone upgraded to 4.2.1 from company. This is important because 4.2.1 upgrades your TOUCHPANEL while upgrading which is called TPUpgrade. If you have bought phone long time before with 4.1.2 then TPUpgrade process is very important.
Some experienced users can upgrade from 4.1.2 to 4.2.1 and perform TPUpgrade process which is required to be done carefully. After upgrade of rom, this TPUpgrade process runs automatically for one time and while it is in progress, user should not touch the screen of mobile until next message appears. Otherwise TPUpgrade fails and phone is bricked.
Coming back to Custom Rom discussion.
Generally custom rom can not damage your hardware because its just a software and at least it cannot damage touchscreen physically. But sometimes touch may stop working if there is any problem in rom or the rom file is corrupted or any other unknown reason.
The solutions is you flash any other custom rom or especially flash latest Stock Rom. Either recovery method (flash from recovery) or SPTools method (flash from pc). Mostly SPTools method solves any such wierd issues.
Hope this helps. Good luck.

Thanks for ur kind reply. Really ur answer means to me a lot.
Now I can safely assure that Custom ROM can make Digitizer not respond due to software error, but cannot damage the same (must work with other Custom ROM or Stock ROM)
For ur kind information, I Had 4.2.1 (updated from service center) before rooting (CWM recovery).
After the problem I flashed TWRP recovery with SP Tool and even in recovery mode the touch didn't responded.
After that I flashed Stock ROM using SP Tool and still same result.
So Surely it must be a hardware failure.
Once again thanks for ur timely reply, if there is anything else I missed out please inform me.

You clearly confirmed that you had 4.2.1 updated from service center.
Then you confirm that you even tried other custom roms and flashed stock rom with sptools method.
Then "Yes" It seems pure hardware failure. Its waste of time thinking why it happened and did you drop phone or not or any other reason.
If phone is still in warranty. Flash Stock 4.2.1 with sptools and give at service center. I dont see any other way out.

Do you have delays occurred in the case of mobile network LTE model it?
I tried two versions of the ROM. G850YDOU2BOG1 and G850YDOU2BOG4 . Both versions have the status of network delay occurred!
G850YDOU2BOG4 This version is slightly delayed sense improvement, but compared to the next version 4.4.4 or smooth enough!:crying:
When the device is in WIFI environment, network status is very smooth. So I had to give an official version of the ROM
Did you solve this?

Here is the link: https://drive.google.com/folderview?id=0B2ORIgaV4iacOVpDTDcxYW4taDQ&usp=sharing
Use only JellyBean! If you still have JellyBean!
You need TWRP or CWM Custom Recovery to do this!
Good Luck!
