I've a c5j5 and was on your v.2 rom. Camera was not working. I tried the official final rom, and it's working and not screen flickering. Do you corrected this on the v.4?!

Hello everybody.

I have the Teclast Air 3G (C5J6). I have updated it on Winddows 10.

In the hope that is better battery life in Standby. There was no better, 3-4% per hour.

This is too much.

Yesterday I updated the Bios to 2.02. I read that the Update 2.02 solves the Problem. The same result, lost after 5 hours 28%.

What can I do?

Mirek,

Loaded your rom 5 v4.1 (wiped data as recommended) last night worked great with the 2.02 bios, switched between windows 8.1 and android without problems, camera also works great on my hg9m, but this morning window is freezing and cannot get past the first screen once I log in, while android still ok, any ideas please, otherwise love that ROM.

Thanks
[Teclast X98 Air 3G] siezed:
Yea just follow that link and use Intel mfg tools to flash instead of the tool, you'll see what I mean in that vid about copying hardware ids, there's a tutorial on the first page called win-android dual boot procedure by frontier that lists the steps too.
[Teclast X98 Air 3G] iscle:
i don't think that's a problem of the rom..
[Teclast X98 Air 3G] minonano:
Sorry guys, false alarm, got it working again, kept pushing both buttons together power and volume, then I got a chinese screen with on english phrase (CRITICAL PROCESS DIED), then I rebooted , got 3 options, only one in english I think to boot to W8.1 and voila, I am back sorry for the scare.

I am sure problem is with windows, not rom, maybe the last windows update, I guess I can restore to before the updates? But it's working.
[Teclast X98 Air 3G] siezed:
Perhaps, but honestly it was kind of a fluke the question he asked was answered, it was specific to mireks ROM that was just released. Anyways I just think the problem with this thread is the popularity of the tablet combined with the problems of having multiple versions and the fact we have so many issues with it. Also there's the dual boot and buggy android stock ROMs, the real solution is a dedicated thread as tecknight has been pushing for, as the threads already too big to navigate so more posts aren't really doing any harm. I suppose if we started turning on each other it might get more attention though and get XDA to give us an organized forum lol

Did you apply the xposed memory leak fix? If not how did you go about fixing it? As for the clean ROM, it wouldn't be such a bad idea IMO, as maybe the way some people use the device they wouldn't care about the stock issues but would still like a perma rooted non Chinese ROM with no changes to the way the ROM behaves just to prevent any total random chance issues that may pop up, like the camera and freezing and stuff (not saying a stock rom would fix those just examples of issues) if nothing else it's a way for people to feel like they have an OEM rooted no Chinese bloat ROM, definitely keep the 4.1 and tweaked ROMs though as if they're working tweaks and fixes are really appreciated :) also didn't tecknight do this anyways? I just never flashed it cause I really want the volume, probably wouldn't flash the "clean" version of yours cause of that unless I had problems too, but seems to be a lot of interest in it.

[Teclast X98 Air 3G] ILUVMONEY:
Hi mirek,

sorry I was wrong. This was the problem when using the flash tool

Link of the screenshot - http://postimg.org/image/g7bck554v/

I've installed both drivers, and followed all instructions. Am I missing something else?
[Teclast X98 Air 3G] billbmsn:
I don't think the camera issues are caused by any tweaks mirek made. I installed Teclast's official 5.0 ROM for Air II, and it broke the cameras on my HG9M. Went back to mirek's latest KitKat, and cameras work fine. They seem to be broken in Lollipop regardless of source. This varies with your model of X98. However, to confuse things, some HG9M owners report the cameras are working with mirek and stock Lollipop.

You can uninstall the offending apps and see if your other apps work after that, but the camera fix for Lollipop is not apparent. In Windows, the newer BIOS plays a role in the front camera not working, at least for me (worked when I reverted to 1.03 then failed again with 2.02). Not sure what is going in Android, but at this point for me, I have to stay with KitKat if I want cameras.
[Teclast X98 Air 3G] iscle:
i have an HG9M and both cameras work fine with the lastest mirek rom.. they worked fine on kitkat too!
[Teclast X98 Air 3G] minonano:
Mirek,

You are correct problem has nothing to do with your excellent ROM, windows was the problem, sorry for the confusion. Great work, thanks.
[Teclast X98 Air 3G] mirek190:
Sorry I'm answering so late about editing bios from your or others copy.

Like you see on the picture in the hex editor - in the row 4000 you have to just edit 2 bits from FE FE to FF FF .

Such prepared the bios will be works well .

I had copy made from c9j8 and edited that bits and got new working bios .

Hi Mirek,

Great, what is the best way to flash it ? I suppose that i must just replace the bin in the folder "X98-Air-3G-andriod-and-win8-bios" and run the flash.bat ?:confused:
[Teclast X98 Air 3G] mirek190:
Yes. You right .
[Teclast X98 Air 3G] Franckydiam:
So i have to rename the C9J8-new.bin with "X98_Air_3G_Dual.bin" or I get an error because it is not the right file bin :o

[Teclast X98 Air 3G] billbmsn:
Hi Mirek:

I see the same FE FE in the saved 1.08 that bricked my Air II, so the same change to FF FF should make it flashable?

So, any saved BIOS from our x98 only need that 2 bit change at row 4000?

Thank you.
[Teclast X98 Air 3G] mirek190:
Yes if you change that to FF FF then bios is work properly ( flashable ).
[Teclast X98 Air 3G] siezed:
Its possible the feature isn't compatible with KitKat, could try flashing mireks new lollipop, he fixed the freezing and its really quite good ATM, some app crashes are the only issues I'm having but that always happens in android so probably not the ROM.

---------- Post added at 09:50 PM ---------- Previous post was at 09:43 PM ----------

Also people with camera problems it would be helpful if you could include any details, like errors crashes what's exactly happening etc. when you say your camera is not working, seems like an odd issue as its not specific devices there must be some other constant that's affecting it. Could even be a bad install or something and a simple reflash would do it, if anyone has tried that let us know so we can all help and not just mirek :)
[Teclast X98 Air 3G] Franckydiam:
:( I tried with my C9J8, flashed the new bios, flashed V4.1 ... not only the camera still does not work and besides I have a booloop with windows

So back to KK v4.2 and again unfortunately bootloop windows, i'm blocked on starting with the message "Preparing automatic repair"):( (with the previous bios 2.0.2 all worked well, apart from the front camera on windows) :(

Update :

I force shutdown after waiting 10 mn with the message "preparing..." and windows successfully started but the camera still does not work (message: "An error has occurred, make sure that your camera is connected and is not used by another application") in the device manager I have an ISP Camera Device driver but it is unknown (?) and he does not update

Update 2 :

After doing a google search for "isp camera device driver" I found this link http://support.lenovo.com/fr/fr/downloads/ds040016, I installed the driver and there miracle the front camera and rear works great in windows

This bios is not version 1.08. It is version 1.05. Checked it with a hex editor and located the version number. I started comparing it to my 1.08 bios and there were tons of differences which made me wonder if it was the same version, leading me to do the check.

I successfully flashed it on my HG9M. Both cameras are working with the Lollipop 5.0 v4.1 ROM of yours. :good:

I modded my 1.08 bios to make it flashable. I successfully flashed it on my HG9M. Both cameras are working with the Lollipop 5.0 v4.1 ROM of yours. :good:

I've attached my modded 1.08 bios to this post, along with your C9J8 1.05 bios with a proper filename naming in case others go searching for that version.

Thanks for explaining how to mod the bios dumps for flashing. :)

EDIT: Bios 1.08 only supports camera OV2680. It does not support camera GC2235. I think 1.05 is the same but not sure.

Hi.

I have the x98 3G dual boot 64gb C5J6.

I installed mirek's lollipop v4 rom and everything seems to work fine and both cameras.

It resolved the brightness throttling problem and sound is super.

It had freezes at the beginning but after a restart is working just fine.

2 issues I have:

1) I can't install apps like google + (says it's not compatible with your version)

Instagram crashes on startup.

2) I had a motorcycle accident yesterday and I broke the digitizer.

The touch works fine for now but I need to find a replacement and a video on how to disassembly our tablet.

If you can help me I would be grateful!

Thanks more for the fine rom.
[Teclast X98 Air 3G] mirek190:

I updated my c5j6 (on default bios, never changed that) to WIndows 10. Faced initial language problem, everything in system was in Chinese. very difficult situation for me. Then used the video of this link to change system to English. Now everything is in English. Windows 10 experience is great. All drivers installed automatically. I installed nothing separately.. Very happy now.

In Android part I installed Mirek V4.1 Lollipop. Running great. Found few bugs. But those bugs are also present in default lollipop ROM. I enlist the bugs.

1. APN setting gets unselected everytime I reboot. (Present in default lollipop but was not present in default kitkat).

2. The data breaks at random and "H" symbol besides signal bars goes way. Sometimes it also happens that data connectivity exists but "H/H+/3G" symbols are not shown.

3. The most inconvenient bug is USSD code failure. (Is present in default KK & LP roms too). Can anybody suggest any solutions for USSD to work.

Great experience with the android part too. Very satisfied.

Overall very satisfied with the tablet. Happy that I bought it.

Lastly, kudos to all the members here especially [MENTION=228925]Mirek[/MENTION] & [MENTION=2651082]tecknight[/MENTION], barring them the optimisation of the tablet would have been diffficult.

Finally installed the v4.1 lollipop. Everything is smooth so far. I haven't tried the camera yet, but navigating and installing other apps from play store is good. No lags or freezes with the UI. The only time that lags is when I play the video using the mx player. By the way, was I suppose to install the codecs when playing the video from mx player? I usually use the pro version and never had this situation before.

Note to all: if you are planning to use micro sd card, make sure you format it into ntfs so android can detect your card.

You might need to close any adb processes that are running for whatever reason, just use task manager, you can't do anything from the windows on the tablet no cause the android partition isn't even recognized by windows, would be nice if somehow we could do it all on the tablet but just doesn't work as far as I know, the only thing I can reccomend is delete everything and start over making sure you didn't forget any steps, like copying the custom config file or copying the hardware ids or correctly installing all drivers.
