@KonstaT
Thank you for the new build. It should be worth a donation for all using it.

A question: I already use your build of 04.12 on my Hi12. Is it possible to do an upgrade to the new build without deleting the data? I assume this would mean to do item 3 (wipe system) but not item 4 (factory reset). Would this work? Thank you.

 

I just installed the new zip plus the Hi12 patch and wiped cache/dalvik. I didn't wipe system or reinstall gapps. No problems so far and Skype login working and win logo home button. Performance seems good too, 58k on Antutu, no lag in Chrome. 

Added 10 euro donation :)

Yes, you can update from previous version without losing any data. Just flash the ROM (+ compatibility patch if necessary) in TWRP. No need to wipe anything or even flash the gapps again.

Done it: In frameworks/av/services/audiopolicy/AudioPolicyManager.cpp delete the elseif block on line 1643-1646.

In cm13 the bug doesn't appear because of https://github.com/CyanogenMod/android_frameworks_av/commit/439e4ed408c21bd65711d279bd5251cef7e83440

The final cm12.1 release came a day early:)

Hah, I really don't mind. Nice work as always! :)

Yeah, that commit came from CAF so probably not a good idea to have it enabled on non-Qualcomm devices.

Here's a patch will fix audio lag in some games. All credits to zltnngy for debugging and fixing this issue.

I cleaned the previous 04.12 ROM with SDMaid and made a Nandroid backup first. Than I flashed the ROM, Hi12 patch and audiolog patch in one go with TWRP and deleted the cash/dalvik. Everything works fine, didn't discover any problem. I thought it might be good to flash the audiolog patch too even if I never had problems with audio before.

Thank you for your efforts. Hope my donation helps you to proceed with your work for Chuwi tablets.@KonstaT

Thank you for great work !

I'm using hibook pro. After flashing this version, brightness slider works well.

Have you change any kernel related SD card? My hibook pro can't recognize SD card anymore. (Samsung, EVO 64 GB)

I tested by EXFAT, FAT32. all format cannot recognize.

I am using Hi10 Plus(z8350) and have flash the 20170128 rom. This Rom does not work well with Bluetooth. It can not pair with my mouse Logicool anywhere2 and my earphone Mpow Magneto. Sometimes it even can not find my earphone. Can you solve this problem?

Hibook Pro uses stock kernel (no kernel source available, couldn't touch it even if I wanted to).

Hardware failure?

Haven't received any reports of bluetooth issues.

There's a known problem with transferring data with bluetooth low energy devices. BLE works with prebuilt blobs from stock firmware but I still rather include open source bluetooth in the ROM.

There's a lot of reports of microsd card issues on the Chuwi forum related to hardware failure of internal card reader. The same thing happened on my Hi12. Mine was intermittent and it looked like it was working in TWRP but then crashed half way through a backup. I removed card and backed up to USB stick instead. I would really like to repartition my internal storage when I know how as I don't use Windows on this device and android only has 10 GB for data and a broken sdcard. 

Bluetooth works fine with my headphones, no problems pairing and audio quality great and very low battery consumption.

I also had troubles with SD card on my Hi12, tried different cards and formats. Actually my card is recognised both in Android and Windows. Finally I use Samsung EVO 64GB. I formatted it in exFAT (Standard) and performed full formatting. Standard means 128kb cluster size. In Windows I changed the driver to an older Windows 8  driver

Here the link were I found the solution for the Windows SD card problem.   https://techtablets.com/forum/topic/reading-sdxc-card/

Until now it works on my Hi12

Hi KonstaT,

 

thanks a lot for your great work. My Chuwi HI12 runs great with your CM 12.1 build. Made a donation yesterday. 

I have two questions.

 

Today I recognized that I have installed this ROM on my chuwi: cm-12.1-20170128-chuwi_vi10plus-Hi12-451609XXX.zip but I'm not owning the latest version, mine is 45160403568 (This version already has stylus support and DUAL OS). So my question is should I stay on this Rom or install this one: cm-12.1-20170128-chuwi_vi10plus-Hi12.zip. What are the differences? 

 

Another thing is that I installed this ROM with TWRP-Version 2.8.7.0.. Is version 3.0.2.0 available for the Hi12? Are there any advantages in updating?

I managed to get my Hi12 re-partitioned for full Android using a gpt.bin somebody made for a similar device from here:
filesystem:https://mega.nz/persistent/mega/bFYiDTja

I reflashed a custom remix folder that had twrp and unlocked boot.img and new gpt.bin using intel phonefashtool. Then in recovery I wiped system and factory reset, then tried to restore my CM12.1 backup of system and data. It seemed to go ok but got stuck on CM animation on first boot into system. I forced powered off then went back into twrp and did another wipe, then did fresh install of CM12.1. After that boot up was normal so I logged into my google account and restored all my apps. Anyway I'm very happy that I now have lots of space on Android data.

IIRC there was difference in sensor hardware so device rotation doesn't work if you've flashed the wrong patch. Both Hi12 patches contain the same files so flashing one over the other will cancel the previous one. You can try as many times as you like (no need to wipe anything).

I've created TWRP 3.0.2-0 image for Hi12 that some reported working - some said it does work. I don't have a Hi12 device myself to test anything with so it's not available anymore. You just need a recovery that's 100% reliable and does what it's supposed to.

There should be no problem restoring a previous nandroid backup after you've repartitioned your device.

I re-partitioned it with gparted, but I had to delete /dev/mmcblk0p10 android_persistent to extend android_data with the unallocated windows space. Everytime I flash a ROM TWRP says unable to find partition size for '/persistent' (see attached screenshot), but it flashes normally and the system is working ... so can anyone tell me what the partition android_persistent and android_esp does? Are they necessary? Is there a way to restore them?

You most definitely shouldn't use gparted (or any other regular filesystem tools) to resize or remove partitions. I've explained partitions in this post. android_persistent partition is used by Google's factory reset protection feature so that won't work. There's shouldn't be any android_esp partition and recovery shouldn't be mounting those two partitions anyway (I guess you do need proper TWRP for Hi12 after all).

You can get your partitions back by flashing firmware with Intel Platform Flash Tool.

I think it was because my backup only had System and Data partitions so there may have been some incompatible Remix data in one of the smaller partitions that only gets overwritten when install is run. I could try to restore data again but don't really need to as my apps restored from Google cloud.

I also have message about ESP partition in TWRP, I don't think it's stopping anything from working but I'm happy to test your TWRP if you get time to do again for Hi12.

Hi there, my battery drains konstantly when the tablet is turned off. At first I thought it to be my error to forget to turn it off. But that was not the case. Has anyone experienced this problem? A guy over at techtablets using Windows experienced that too. He changed something in Enery Options... But on Android ?

Kind regards, Skyfire

If fully powered down (not just screen off) drain should be negligible (should last for months). Remove power plug before shutting down or it will boot to battery monitor OS so won't be completely off if you latter remove charger cable.

[Guest Skyfire]

Thanks I'll try that.

Hi, in windows I disabled energy saving or hybrid mode to be sure that Windows completely shuts down. Before, I had problems that the processor constantly worked and slowed down the performance in Windows. I will also check the Android shutdown with/without power plug.

[Guest Skyfire]

Seems like I found the solution... Without an sd card in the tablet the battery loses less than 1% over night. I'll try again with my sd card inserted...

[Guest PalmTrees]

@KonstaTI know this is the final build. Just wanted to ask if it's possible to change the charging LED - blinking while charging is a minor annoyance. Any quick fix to keep it stable?
