Hi . . .

Looking at the threads of your links (this) I read that in addition to Taipower, you have to use a hex editor. Can you please explain?

I would have understood well, even before starting the procedure :)

EDIT

Last night I upgraded to Win10. There are further complications?

Hi everyone, I have upgraded my Tablet from windows 8.1 to 10 ( via windows update) , everything is fine except the touchscreen which goes crazy and register extra touch when you touch the screen. Does anyone know how to fix this?
[Teclast X98 Air 3G] chrissss91:
If you saved your "hidden key" with TAIPOWER utility, just rewrite your "hidden key" with TAIPOWER utility.

If you just wrote it on paper, use the following file : http://xdaforums.com/showpost.php?p=62057872&postcount=10694 and use notepad++ or an HEX Editor (to be sure not to break file structure) to replace my XXXXX-XXXXX-XXXXX-XXXXX-XXXXX by your own key.

Bus Pirate 4 + Flashrom patch to unbrick Teclast X98 tablet

Hi Guys.

I'm right here to write you I made a sure method to unbrick your Teclast tablet after a bios upgrade crashing, with a Bus Pirate 4.0.

I read lots of methods right here and on different blogs which sponsor the CH431a based programmer and the direct connection on mainboard, how if it was an absolutly sure method without risks for your tablets, but this thinking is discouraged from the same chinese producer of the programmer, so... Do you have any idea what this is all about?!

Trusted in me, it's only a part truth, so don't think in people likes tecknight (for example) that speak freely about this method without tell you any possible damages you can get.

Even if you read about successfully unbrick online, this doesn't means that the method CH431a is without risks, if it taken lightly.

After days of calculations, measurements and non stop test; I achieved a method HW and SW that lets you much more serenity and less possibility to destroy your tablet.

I'm preparing an article about it asap. If it's in your interest, stay tuned on creativityslashdesign.tk.
[Teclast X98 Air 3G] siezed:
Just saying, i dont think anyone said it was a surefire way, ive read multiple posts on here about how its a risk and not designed for this tablet, tecknight is just most likely to help people trying to do it. its more if you have a bricked tablet it was basically useless and there wasnt much risk in losing something thats useless if its your only option.
[Teclast X98 Air 3G] kRel:
I realized that if you use Taipower, * to save the key is sufficient to use Taipower also to rewrite it.

Instead, if it is written with a pen or using Belarc, you you must use a hex editor, starting from key

[Teclast X98 Air 3G] cosmok82:
tecknight was an example.

It's most likely to help people after developing a method tested and not just after having read something distractedly from somewhere else. That's how I feel!

I don't suppose it's the better method, but a good method to unbrick in safeness based on my personal experience, with my personal hardware.

It's too much simple to say "I read online that... " and then to suggest a 3.3V programmer without the right know how and ignoring what writes the manufacturer. It's dangerous! So it's an error in general.

I have unbrick my tablet with successful and I want to share my experience with all you, without follow the today trend.

An informed user is a safe user.

P.S.

Take a look http://goo.gl/ws0unr . Do you notice something close to 3.3V programmer in picture :D ?

hi guys,

i've tried to flash mirek's latest lollipop version to my air 3g (c5j6)..something went wrong...it erased system,cache...but couldnt start installer... i later tried factory restore, but it didnt work...and i havent created any back up... cant log in to android now...windows ok....is there a way to install/get my android back??
[Teclast X98 Air 3G] jsager33:
I didn't do any editing other than to make them flashable. 2.02 was already flashable. My camera works with 2.02 on my HG9M so I assume it's made for camera OV2860 and not GC2235. I'd be curious to know if anyone with a GC2235 has camera working with 2.02.

[Teclast X98 Air 3G] andreasph:
I've followed this thread and came to the conclusion that flashing Bios 2.02 seems to be a dangerous operation. There are too many cases where the tablet is bricked afterwards. It's not an easy decision to take this step...

What are the main reasons for the flash error? How often does it occur? Is there anything I can do to prevent the flash error?
[Teclast X98 Air 3G] siezed:
Well I think we have a language barrier here, I simply meant people were willing to try the programmer knowing the risks because they had a broken tablet anyway, tecknight and anyone using the flash tool were well aware it was 3.3v and a risk, I'm just saying it seemed like tecknight and others were endorsing because they were most likely to help people who had already decided to take the risk. They were pretty clear it was a risk, as with anything you do that would void a warranty.

Anyways moot point besides clearing the helpful peoples names on this site, its good you have found a safer way, but I'd also be careful suggesting its foolproof because its pretty clear a lot could go wrong =)

[Teclast X98 Air 3G] billbmsn:
If you are concerned about the 3.3V output, here is a programmer that supports 1.8V.

http://www.amazon.com/Signstek-EZP2...e=UTF8&qid=1440365153&sr=1-1&keywords=EZP2010

No extra hardware required other than the same adapter and clip cable used with the CH341A. Is there another problem with this that Bus Pirate addresses?
[Teclast X98 Air 3G] siezed:
You're right its definitely dangerous, the brick afterwards is sometimes totally random so there's no way to ensure no brick, I think the only known bricks are from flashing a non flash able bios. Everything else is educated speculation, making sure you hard power off after the flash is completely done is one theory but people have ended up with bricks even doing this. People also suggest using android to flash because less people have reported a brick from flashing via android, but that could simply be because most use windows. Other than those just follow standard common sense, make sure the tablets secure and won't move or be bumped, same with the cord, make sure to use the stock cord, don't run anything on your host PC while you're flashing; reboot before the flash just to make sure there's no windows updates or random programs running. Also if you get a hang leave it alone, it could recover after a long time, like hours, I've never seen this happen with flashing this bios but its happened installing firmware before, and if I had tried to reset I'd probably ended up with a brick. I think most people here have flashed 2.02 bios, its one of the most useful and popular things you can do so that needs to be considered when looking at hiow many bricks, I'd say its still a pretty small percentage.

[Teclast X98 Air 3G] cosmok82:
You are right! Absolutely I didn't define my method "foolproof", but if you ask to me a percentual, I say a 75% of possibilities to unbrick your tablet with no damages. All it was cabled, for this particular case.

The wrong case are divided as follows...

There's a 15% depending on user know how (in electronics and programming), 6% from material quality (I have had some problem with it) and the last 4% from pure bad fate.

Hi [MENTION=2198172]mirek190[/MENTION] , we know that if the tablet switch between 3G (UMTS in general) and 2G (edge) we have freeze on display (due to Antenna or Edge frequences?). So, is it possible to disable 2G?

In Settings->More->Mobile Networks->Preferred network Type:

- 3G

- 2G

Is it possible to add "3G Only" on your next rom?

- How to force 3G only mode on any Android device
[Teclast X98 Air 3G] siezed:
Oh that is the android way, its just using adb and android to flash instead of flashing straight from windows on the tablet, but now that you mention it maybe that's why people don't report they used android because they assumed android meant actually flashing from within android, either way tecknights tutorial is the hypothetically safer of the two methods =)

As for the bios key, I just used a utility to get the key and took a picture with my phone, takes 3 secs and ultimately serves the same purpose, if you wanted to re-inject the key you can but its only there in case you have to re install windows from scratch for some reason, i n which case its the same as physically having the key.

Which has 48mb/s read and 13mb/s write.

Will the tablet support faster cards than this?

Because there is a Samsung Evo Plus that has 80mb/s read and 20mb/s write.

Which do you recommend?

I heard that the tablet supports 128gb also, but only in Windows?

Is it possible to partition an 128gb card and use it in both Android and Windows?

[Teclast X98 Air 3G] joq3:
Okey, but did you buy this for your phone, or the Teclast X98 Air?

Because from what I have found it uses USB 2.0 and the micro SD slot is limited to a read/write speed. But I don't know if it can do 80mb/s read and 20mb/s write as the Evo Plus has got?

We have the same C5J6, I don't know..When my tablet switch from 3G to 2G and want to came back to 3G (search for better signal) the display freeze)..

So this is the procedure:

1) Install Truedialer if you don't have the stock dialer

2) From dialer write: *#*#4636#*#*

3) Enter in Info Tablet

4) Serach for "Set preferred network"

5) Set it as "WCDMA Only"

What file system do you use?

ext4 for android and exfat for windows?

I have heard that NTFS is the only one that is working on both Windows and Android at the same time?

But that NTFS is much slower?

So what do you recommend?
[Teclast X98 Air 3G] mirek190:
Android handle NTFS and fat - I have 128 GB card in fat [emoji4] but card is not super fast .
[Teclast X98 Air 3G] joq3:
I didn't think 128gb was even supported by Android?

I have read somewhere that NTFS is slower than exFAT and ext4.

And FAT32 is useless as you can't store files over 4gb.

Do you notice that NTFS is slower?
[Teclast X98 Air 3G] mirek190:
That's true for fat 32 is limit 4 GB...

But not doing unnecessary writes like ntfs.

Ntfs - hmm that's format in my opinion is not good for sdcard.

NTFS wasn't designeted for flash memory - makes many writes ...that can damage limited write flash memory.

I had memory card ( 128 GB ) in ntfs ( I never used ntfs ealier on sdcard ) in tablet and after 4 month suddenly stop writing data - I could only read data.

I've never had such problem before .

Lucky I replaced it on warranty.

As it might break the micro SD-cards?

Hi all,

I have a question - out of interest mostly, it is not such a big deal - on the orientation of the screen (android). Some apps allow all 4 orientations, some less. Portrait is then usually ok, with camera high, but landscape is (in my case, c8j7) with camera and volume controls at low side, which is a bit strange. Is this the case with all models? Is there a way to change the default orientation in a system file (rather than using an app)?
[Teclast X98 Air 3G] mirek190:
In spite of limit of 4 GB per file I'm using fat.

Maybe I'll be able to add exfat to rom next time.
[Teclast X98 Air 3G] joq3:
That would have been amazing! I have many 720 and 1080p movies over 4gb, so I can't use FAT32.

But exFAT would be awesome, to share the same card on both systems!

EDIT: Maybe you can implement this: https://github.com/CyanogenMod/android_external_exfat
[Teclast X98 Air 3G] cattolicboy:
Yep, I agree with mirek, fat32 is more fast and reliable for sd card: I understand the matter about big video files (I'm a movie's freak as well) and I solved using or re-encoding to have smaller files than 4gb.

[Teclast X98 Air 3G] MadNBG:
I think, most errors happen, because people shut down the tablet regulary instead of hard-power-off after flashing. (While flashing, you run Android with debbuging on. When flashing is finished, you should press the off button untill the tablet goes of.)

As I red (and I have been reading a lot here) - and my impression is - the flash.bat is safe. You must hard shutdown after. That's the trick!

This is my impression, anyone else?

[Teclast X98 Air 3G] billbmsn:
The problem is that you, I and many others need the BIOS to include GC2235 camera support rather than OV2680. We happen to have submodels of the 3G or Air II that have the GC2235 front camera, and all the recent BIOS that have been posted are designed for the OV2680 instead. Some older BIOS versions I have flashed, like 1.03, 1.04 and 1.05, support the GC2235, so you get a working front camera in Windows, but you lose the OS switching support. Editing BIOS is way, way beyond my pay grade.
