Teclast X98 Air 3G/Air II Mirek190 V6 Custom Rom Released

Teclast X98 Air 3G/Air II Mirek190 V6 Custom Rom Released

Mirek190 recently released V6 of his X98 Air 3G Rom. This latest build fixes some minor bugs and has some tweaks (see the changelog below) I recommend this Rom to Air 3G/Air II users due to the fact it’s tweaked for performance,  battery savings and its light weight. Not full of bloat and Apex launcher replaces the Teclast’s laggy stock launcher. https://www.youtube.com/watch?v=j0-QymhI9aM Changelog:

– google core apps ( weren’t complete and I also updated them ) – updated xpossed to v75 – fixed audio distortion in ringtones, alarms , notifications – completely a new network configuration for WiFi and hspda – should works faster and quicker ( at least works for me ) – added some improvements for the File system ( like no merges, rq affinity, etc ) – cache for external memory card increased to 4096 KB – other minor things I don’t remember – modded my flash tool to works with droid-boot 4.4 and 5.0

  1. BIOS(c5j6) firmware programmer teclast x98 air 3g ?

  2. Really a lit of unanswered questions here. Guess im gonna choose a other brand

    • That’s because people should post questions in the forum, not in the Mirek custom ROM thread for the X98 3G. Yes, I think you should go for another brand, I’m certainly not the official support for Teclast or this custom ROM.

  3. Hey I just bought this tablet off eBay, it has dual boot android 5 and windows 10 on it, the model number is M5C5,
    the android side has the foreign stuff on it and the windows 10 side is threatening that the license will expire in 10 days.. I have watched your videos on the other models, but would like a written explanation on the procedure to revamp the android 5 with the debloated american version and a permanently activated windows 10 with more room or memory for the windows 10 side

  4. Hi, sorry for my “silly” question but how install this Rom?…

  5. I have Teclast x98 Air III 32 GB with only Android 5.0. Will this ROM work on my tablet? Can somebode also give instructions how to flash to new ROM? Thank you very much for any response.

  6. non riesco ad estrarre file scaricato da google X98 Air 2 Android 5.0 Mirek190 V6.0-ultra-light chiedo aiuto ..grazie

  7. Hi Chris ! Which one of the 4 downlaod links on this page did you use to flash your Teclast X98 Air III ?

  8. Anyone else suddenly got a Play store error logging in? Did work and now stopped. Have cleared caches n re added acct but no joy

  9. Hi Chris, I recently purchased a teclast x98 3g. I Saw you mention in a video that you found a micro USB to usb 2.0 part that could allow storage exchange between drives while simultaneously charging the device. Do you know where I could find this.

  10. I can’t open Instagram, It always crashed even from V5

  11. Does this ROM require a bios update? I have the original bios and os on my teclast air ii HG8N. Is there a concise guide to follow?
