Havoc2.0 treble rom doesn't boot for me.

---------- Post added at 05:34 PM ---------- Previous post was at 05:21 PM ----------

I was stuck in recovery bootloop. I went back to stock via flashtool then tried again. I discovered that "fastboot erase system" doesn't work so that's likely the problem. Go into twrp and format data (you will lose all your data so move any important files to PC or something).

So format data > fastboot flash system nameofrom.IMG > reboot.

I decided to just flash resurrection remix treble ROM and stay on that for not. Pixel experience works but I was having WiFi disconnect and not sure if its just my router acting up.

Curious how you got you twrp to work , we cant get twrp to wrok on current build
[Device Reviews and Information] Imperial.mack:
Twrp is on the first page.

Flash with sp flashtool or get the IMG file and use

My battery is only charging to around 80% anymore. I don't know what happened.

Does anyone know how to fix it?
[Device Reviews and Information] Opmovers:
I think he's referring to the fact that the third stock release for chuwi and gearlabs 3 has an encrypted data partition, as such no one's able to create a backup with TWRP because of this.
[Device Reviews and Information] amg314:
Try this advise from page #3 of our forum:

Bug - Battery only charges to 98% with supplied charger and cable. (Solved) Turn off Intelligent power saving standby and Battery saver. Unplug and Run the tablet down to 0% using something intensive, turn on again, Run the tablet down to 0% using something intensive then charge to 100% with tablet switched off.
[Device Reviews and Information] Imperial.mack:
Ok I can't make a twrp backup of data partition (other partitions, yes) currently. I formatted data for start fresh but it seems like it encrypts itself once I boot into twrp.
[Device Reviews and Information] amg314:
Remembering your desire to get a working TWRP, I found the following post on XDA:

How to remove data encryption in TWRP by dwapking

*----------------------------------------------------------------------------------------------*

The mehod involves the loss of all /data.

Backup your data thru Settings --> System --> Backup or thru Titanium Backup before making strong steps.

I have NOT tested this method!
[Device Reviews and Information] Opmovers:
Revisiting encryption issue.

This is interesting and I have not tried it yet but I will Tinker with that a little bit. Although it wouldnt be a solution for someone who currently has their phone set up and spent a lot of time doing that.

I actually just discovered something that looks promising. Although it would require a rooted ROM and maybe a purchase from the Play Store. I think it was Alberto who introduced me to this app. https://elementalx.org/exkm-user-settings/

For those of you familiar with Elemental X. In the user settings tool, it seems that there's almost an endless amount of modifications possible. I'm hoping that someone might help with finding a quick and easy method to decrypt the data partition with the user settings tool in the ElementalX app. I'll be searching as well.

Be careful though it looks as though this tool could really mess up your device if you're not careful.

Cheers!

So looses certification does it?!

That is really the main reason I was going to update! Now that I am back from traveling the summer away I will start reading up on this and maybe update my Chuwi before my 3 month trip next spring. Maybe I am the only one still running original stock ROM 8.0 but everything on my tab still seems to work o.k.. (Except things like wired ethernet via OTG etc....) I am using ATT mvno Consumer Cellular as a carrier in sim 1 for vd&t, and a google fi T-Mobile data only sim in sim 2. Both slots get 4g when traveling but at home ATT must have something a miss in my local cell node as it is always 3g. FYI my Moto g6 works great on Fi also and uses Sprint cdma at home but running around USA in RV or Amtrak routes across the west I end up using all of the Fi available carriers cdma/gsm pretty well! Looking forward to using this tablet across the Austral Asia and Indian ocean areas.

Hi,

Originally, I had a problem installing GearLabs ROM.

I unlocked the bootloader and installed GearLabs ROM in fastboot with the two commands (boot and system), and the result was bootloop. However, after restoring original ROM with SP and then installing GearLabs using SP again resulted in success.

So, thank you for your effort, so far I'm happy with my new tablet. :D

[Device Reviews and Information] uncleabubear:
Good question. You can be the guinea pig!
[Device Reviews and Information] strawsy:
Yeah I've done all that. I had to get more advanced and bypassed the battery entirely and can power it on but it will not boot, just chuwi logo and then turns off.
[Device Reviews and Information] fasty:
Update: For me, after a while using 20181010, I get return of "Sleep of death" seen by many owners: Tablet requires hard reset (very long button press) to awaken from sleep.

I've tried a factory reset, problem gone away, but suspect may return in a few days like before.
[Device Reviews and Information] amg314:
As far as I understand you, you disconnected stock battery and charged it separately off the tablet.

Then you soldered fully charged battery back without any positive result.

I am afraid it means that you have hardware problem((

Did you tried to do factory reset?

Has anyone tried to install dolby or xposed with magisk?

[Device Reviews and Information] kirk8:
I tried the previous steps in flashing treble ROM but I get stuck at fastboot mode, what do you have to day guys?
[Device Reviews and Information] strawsy:
That's correct. I was able to charge the battery separately and reconnect. I also tried another battery but same result. There's something causing the tablet to not get passed the initial chuwi logo. I can get to thr screen for recovery, fastboot and normal but same result for each of those as well. It seems the usb isn't being recognized but the port is not loose. My next step is to solder a direct connection on the board. Either way this will be my first and last chuwi product. Lasted a whole 3 months.
[Device Reviews and Information] amg314:
The fact that Android starts to load indicates, IMO, a crash in the OS.

Since you have access to stock recovery, you can try reset to factory settings.

It will wipe all your personal data((, but may be it could fix the problem.

PS Tell me if the charge controller is working (is it possible to charge battery after you reconnect it to tablet?)
[Device Reviews and Information] strawsy:
Well that's the thing. Android doesn't start to load. It's just the first chuwi screen,not the second. And I don't have access to recovery. It allows me to select recovery but it doesn't actually boot recovery.
[Device Reviews and Information] uncleabubear:
Can you flash stock with SP flash?
[Device Reviews and Information] strawsy:
The tablet isn't recognizing usb at all. I have tried many different cords, ports, 2 different pcs. Either the port is somehow damaged or the usb controller on motherboard is somehow not working. My next step is to hard wire micro usb to motherboard and see if that works.
[Device Reviews and Information] uncleabubear:
I would send it back for a refund if I was you.
[Device Reviews and Information] strawsy:
Too late. It was rooted so they wouldnt give refund. Since usb wasn't recognized I couldn't unroot. I also already opened it up to troubleshoot further. I will keepessing with it in hopes of.l getting it working but I definitely won't purchase chuwi anymore. Never had this issue with any other device.
[Device Reviews and Information] amg314:
Try to examine the PCB carefully with a magnifying glass. Maybe you will find a defect, such as poor soldering, short circuit, etc.

Good luck!

UPDATE:

-couldnt install treble( ILersonaly wont go through many trial and errors)

------Font manager ------

-detected malicious program on newly flashed rom

I my tablet (newly flashed august ROM), detected a malicious program called font manager, going a few days back : i was severely stressed because stock apps would crash all the time(wost experience was I had to use speech to text because keyboard wont work) so I decided to flash the Rom again and again only to find the problem is there , after (unexpected)detecting this, it solved the problem

Any insights?
[Device Reviews and Information] uncleabubear:
Look at downloads, in original post
[Device Reviews and Information] amg314:
I have NO Font manager app in my August ROM.

Thus, this app most likely was installed by you. And you can uninstall it in a common way)))

I found two versions of this tablet on the gearbest. X20 and x23 which one to choose? Probably twrp only works with the x20 version? I care about twrp and magisk
[Device Reviews and Information] amg314:
Please Google the matter: helio x20 vs x23

https://versus.com/en/mediatek-helio-x20-vs-mediatek-helio-x23

One can see, that x20 and x23 are pretty similar, but, IMO, x23 is better.

Magisk is not CPU dependent)). TWRP will work on x23 in the same way as on x20.

i'm trying to upgrade to gearlabs rom and i cant... i do all with bootloader but when i end all process OK and do a bootloader boot, all time reset with TWRP and i can't start the system.

What i do:

1. Press Volupe + UP for start in fastmode

2. Select Bootloader

3. Connect tablet and "fastboot oem unlock" confirmed with volume up

4. Flash all (boot.img and system.img)

5. Lock bootloader again

6. bootloader restart

AND only can start with TWRP, any suggestion or solution?

Ah, I see that in the first post puts that it's possible to flash this ROM with Flash Tool, but when I download the ZIP it contains only system and boot. How can I reset factory and then install it with flash tools?
[Device Reviews and Information] Imperial.mack:
Just search online because it's too much to maybe reply. Example: [youtube]b8rL-eSz5GM[/youtube]

Once you have stock, follow instructions on first page.

Thanks but this tutorial only shows how to flash a stock rom, i need to flash custom rom with flash tool or prevent stuck when i do it with bootloader.

Steps I took to migrate from Stock Rom/ Stock Recovery release-keys 20181010 to Gearlabs V3 20180907 (release-keys 20180809).

1. If not already Enable Google backup. Settings>System>Backup>Back up to Google Drive and also Back up now.

2. Enable developer options. Enable OEM unlocking. Enable USB debugging.

3. ADB reboot bootloader.

4. Fastboot OEM unlock.

5. Fastboot flash boot boot.img

6. Fastboot flash system system.img

7. Fastboot reboot.

8. Restore from cloud.

9. (Optional) ADB reboot bootloader, fastboot OEM lock, fastboot reboot.

( I had a weird situation where after flashing Gearlabs I had no working keyboard, so had to skip all prompts, enable japanese keyboard, add us keyboard, make us keyboard default, factory reset, restore from cloud, add uk keyboard, remove us keyboard.)

Help me, please !!! Hi.

Next week i received from Bangood the Chuwi hi9 air.

Since first start after the tablet configuration , mounted the sdcard and one Sim card, many and many issues appeared

1)The tablet suddenly turns off and restarts while normal use.

2)Many appllications when started suddenly crushes.

3)It's impossible to install several apps both from google store and from unknown sources because the installation fails.

So using the combination keys i went in the recovery mode to make a factory reset but nothing changed. All the issues appeared again!!!!!

I don't know if those issues originate from the tablet's hardware or from a bad firmware or from

a bad firmware's flash from the factory but the result is that MY NEW TABLET is completely unusable.

I'm really very disappointed and angry.

I hope someone could help me to solve all those problems.
[Device Reviews and Information] uncleabubear:

IMO, there are no big differences. So you fight with windmills((

P.S. You can easily examine GearLab without installing this system. Just copy system.img from GearLabs_ROM_v3.zip to HDD and click on system.img in Total Commander. You will see a complete list of installed programs and much more.

For example, one can see list of priv applications on the right side of screenshot))))

I have several question about this tablet before I buy it.

1) Will this work with CoPilot which a GPS Navigational app with voice commands.

https://play.google.com/store/apps/details?id=com.alk.copilot.namarket.premium.rv

2) Are there any problems using wifi and bluetooth at the same time? There is a competitors model that has issues with this.

3) Has anyone compared this to the Huawei MediaPad 5? I know the Hi9Air is cheaper, but Huawei's price has dropped some on Amazon.

4) After reading through all 97 pages I understand this tablet will not do Netflix in HD. Will it do any streaming in HD?
[Device Reviews and Information] Fredoslaw:
It has Widevine L3 certificate, so you can stream anything if L3 is enough for this service. For example Netflix and Amazon Prime is SD, but YouTube is 2,5K. I don't use any other streaming services, you have to check yourself what Widevine certificate they demand for high resolution.

Comparing to Huawei MediaPad 5 i can say that screens are similar, Huawei has smoother working interface.
[Device Reviews and Information] NikosD:
Using NewPipe, an open-source alternative of YouTube, you can even play YouTube clips at 4K30fps without problems.

Probably you could do the same with Vanced YouTube, but NewPipe is easier to install and doesn't require to root your device.

Now I'll request more refund to gearbest, because is not possible that release these lousy rom, so next time gb thinks two times before sell chuwi products, this product causes by developers and management, the real value is not more than 110 use. Now who will recive money, will stop to recive It, next time I don't buy more chinese low branded products, now I wait 5 or six year to buy high price products, so chuwi and others brands will close soon and all people (and say all........forums etc....) take money, stop to recive It!.
[Device Reviews and Information] Alberto96:
My Hi9 Air screen is also self-cooking on each side (fading on dark backgrounds), I am not so satisfied with this product quality to be honest. The 4G antenna is almost dead too, all reasons why I am not so active for this device, i guess it is going to die really soon -.-
[Device Reviews and Information] Axellx:
I thank you for the effort put into improving this ROM. The bigger issue of this tab is the software, 09/05 was pretty good they increase screen saturation and improved gaming performance, in 10/10 they returned to old issues decrease saturation and gaming performance, or are stupid or they do it on purpose in my opinion is the second option
[Device Reviews and Information] reubenray:
Is this due to the custom roms? I plan on keeping mine stock if I get one. With these recent reviews I may have to get the Huawei MediaPad M5 instead even though it cost $80 more. I also plan on only using wifi.
[Device Reviews and Information] Alberto96:
Of course not, both issues have been reported also from other users that were running the Stock ROM, way before i have released the GearLabs ROM.
[Device Reviews and Information] Alberto96:
Let's say that techain, responsible for the software, is the classical company that doesn't know how to handle properly this MT6797 platform, part of this is also Mediatek's fault since the BSP provided to OEMs is already bugged.
