I bought Chuwi Hi8 about a month back and consistently it crashes after some usage. Happens both in Android and Windows. Updating Windows didn't help. I don't see "System update" option in Android mode. Factory reset doesn't help either.
Do you guys experience the same or is it stable for you? I'm trying to check if I got a lemon or others see this issue as well.
Can someone guide me how to set it up to get a cash dump and how to install GDB in it for dump analysis? Currently I have no clue why tablet crashes every now and then.
Bad experience
I have bought chuwi hi8 via DealExtreme at a very hugh price 109€ and it is the worst tablet i ever tried. The machive overheats all the time. If you restore windows you lose the O.S. swaping app. Youtube on android is limited to 720p. The ambedded video on android crashes 40% of the time. And the Multi user options on android does not exist.
If you brighten the screen on windows via energy saving, windows crashes all the time and becomes unusable, The audio works via WDM compatibility.
See why i write this post on my videos:

And finally the RMA is very difficult.

Thanks for sharing! Yep, it crashes every freaking time. Windows throws blue screen, and Android just hangs. Such an unstable product. Does this company have anything like QA control?

Hey there!
Mmm... Quite weird what you said... :S
Mine is perfectly working since I bought it, both android and w8.1, and since this very morning it's been upgraded to w10...
For the upgrade, I just needed to put a microSD for the w8.1 backup abd after 3-4h of download+backup+install is working just great.
Have to try the windows utility to reset the tablet? Or just tried the factory reset on android?
Thanks for reply! Yes, I've tried Android reset which brought back Android in Chinese mode, so had to follow a video on youtube to get it back to English. But tablet still consistently crashes after some use like in 5 to 10 mins of usual browsing. Probably I got a lemon?

Hi,
I've similar issue but with play store only. Permanent crash. Many Android reset without success.
No issue on windows... instead windows himself ^^
Could be a bug in Android build or your device overheating?
I have the tablet for 3 weeks now and im using it daily. I don't have anything to say bad about it, only the fact that it kinda gets warm to the touch if I use it a long period of time, nothing abnormal.
No real issues so far
Raheem, I bought two recently and I do not have issue with either. I notice when play a game, it does get warm and after an hour or so, the thermal limiter comes on. Battery life is only about 3 hours of on screen time.
Android 5.0 reset.

Howdy guys,
after a little help please. I am using energy cookie rom since may with little problems.
However, recently the phone started switching itself off. I noticed it whilst streaming with 'myplayer'. Then it did it when i received a text message. Now it is doing it all the time. I have started playing a game called land, air, sea, warfare (great game btw) And the problem is worse not only does it just switch the phone off but it somehow manages to make the phone do a hard reset???????
When the phone switches back on it says it is the first time the phone has been on and goes through asking me which carrier i am using?
Also sometimes it wont switch back on and i have to false a hard reset to get it to work. I have done about a dozen hard resets since yesterday.
Any ideas please? Btw i did perform a task 29 and a hard reset after i installed this rom.

My two pennies on this:
1. Perform a task29 again.
2. Install a stock ROM.
3. Install HSPL3.
4. Perform Task29 again.
5. Install the ROM again.
Should remove all the problems and get you a good clean ROM without probs.

Howdy, thanks for taking the time to respond. So you think the issue is probably software related rather than hardware? I only ask cause that 'game' is 40 mb and i was wondering if maybe it is too resource hungry for my phone and maybe i have an issue? Ram, cpu etc?
Either way i will try and change the rom first.

I am using energy cookie rom too. I used to have the same problem like you, and i did some easy things to solve. It's ok so far and i hope to help you.
- Flash new stable radio after flash rom (someone say should flash radio in advance, but not for me). V2.10.50.28_2 is good to me.
- Turn off auto lock. It makes some disadvantages to you, but helps your device from death - sleep.

I doubt it is that game resource problem. Most probably some software conflict only. HD2 can handle 40mb game files easily.

Guess your game has got some serious conflict with the ROM and is corrupting some reg settings or some ROM settings. Probably you are better off not installing that game again. Moreover, write to the developer of the game about this issue.
With regard to the phone, just follow the same advice I gave in the first post. Time consuming I know, but your device will get back to normal. Fingers crossed.

looks like something is going on? I performed about 5 hard resets and finally got the phone to boot up. But it is hanging for everything now. I turned on bluetooth, i tried to access sense and both caused the phone to hang. So i will try your advice again, tomorrow. Thanks,
well that game definitely conflicts with the phone.
i flashed a stock rom from the sd card as advised and finally got the phone working aok. within 10 minutes of installing and playing that game the phone is back to her old ways of soft/hard resetting.
is there a way to check that it is not a hardware issue?
thanks again for all your help.
Hey!
One week ago, I bought my Archos G9 and since then my device crashes around 7-8 times a day. I have the newest firmware with root enabled on my device and disabled everything I could imagine (window animations, gps, etc.).
I have know idea why it crashes. There is no special pattern. One moment it crashes during browsing, the other while playing doodle jump, etc. Maybe it's because of the 512MB RAM? I already put a swap file on my device, but it didn't help at all...
hope you can help!
Ram has nothing to do with crashes. Try rooted firmware without custom busybox, download in Modified Init thread (custom busybox seems to be responsible for quite some problems)
tapatalked from Desire
thanks for reply!
My device is already running on this custom rom: http://forum.xda-developers.com/showthread.php?t=1480906
EDIT: Seems like there is something wrong with the CPU... while performing the SetCPUs stresstest, my device crashed. Is it a general Archos G9 problem, or a specific problem with my device? I also noticed, that the back gets relativly hot... This happens only while i charge it.

When i first bought mine it also crashed every now and then and what i did was a full reset from the settings . Since then no more crashes on apps , so give it a try
If u dont need it, make sure bluetooth and gps are off, that always seemed to help me

I've had mine for 10 days now. I haven't rooted it yet - it's running the stock 3.2.80 firmware.
For the first 4 or 5 days, it seemed fairly stable - odd reboots, but nothing too bad.
Now, it won't stay running for more than 2 or 3 minutes from reboot before it freezes and I have to long-press the power button to shut it down. Sometimes it just reboots on it's own. But after each reboot, it stays running for less time than the last. If I let it lie down for a few hours, it will return to running for 2 or 3 minutes before freezing or rebooting again.
Mine also seems to get pretty warm on the back.
I've tried getting an RMA number from the Archos website, but that page doesn't work (shows a MySQL error!). Had to resort to emailing their support team a couple of days ago, but still waiting for any response.
I wish I had bought it from Play.com instead of direct from Archos - at least I could have returned it easier. All in all, I'm not very impressed so far.
BTW, I did do a full, factory reset, but it's made no difference.
Nothing worked, i already deactivated GPS and bluetooth and did a factory reset too.
I think I'll wait for the ICS update and hope, that archos will fix the problem... I don't think it's a hardware issue...
Try 3.2.79 version, IMO it works overall better than 3.2.80 but I can't test 3g stick. Wifi however behaved better on .79.
Note- you can't downgrade official firmware (AFAIK)
I believe there is a way of downgrading official firmware - I may give 3.2.79 a go.

Hi guys,
Last night while i was out at the pub i managed to win a Tokio Tablet from one of those games machines.
I booted it up this morning and found it was running android 2.3.3.
I managed to root it with gingerbreak, superuser works etc...
I was wondering if anyone has every used on of these and if it's possible to flash a different rom to it?
The default rom is so clunky and slow, kinda makes the tablet useless.
Any info would be much appreciated
I think i have managed to find a recovery menu or something similar but when you boot it up while holding the home button it boots onto a screen saying "unexpected updater mode"
also, bump

Tokio freezed on start up please help!
My 10 year old lad won one of these tabs and used it for a few hours. His cousin downloaded a starwars screensaver and all seemed ok. However, we put it on this morning and it gets to the "android" screen at start up and freezes. We cannot get any further. I have tried resetting it through the little hole, I have tried attaching to my pc to see if i can get into it, nothing.
My lad is upset as you would imagine.
Any help appreciated.
Thank you.

I search a lot spent hours but didn't find official or unofficial ROM for this Tablet. every question is unanswered like how to Flash, Root, CWM
Tokio 2 vanilla marshmallow 5"
Won one at the arcade, disappointed it wasn't 'L', as was looking to root it. But 'M', although with Google Play, doesn't have all the rest of the Mountain View GAPPs, just about Vanilla Android, and boy does it fly. Battery good so far, easily beats similarly spec Alcatel Popstar.
Soft buttons transposed at bottom, but not a biggy. Cleaner on longpress home button. Seems to be better color with big apps like Chrome, Opera etc., but just using bog standard nakedbrowser.com/android for now. There is a 7.5" Tokio iv in the arcade now...may well get it for summer.
Pity there's next to nothing about them in English on the net.
Earlier this week I brought you news that the Android 4.4.2 KitKat update had finally started rolling out for Dell’s Android budget slates, the Dell Venue 7 and Venue 8.
A few days later, a lot of users have updated to the new build and at the same time the first bug reports have started pouring in.
Some owners don’t report anything being wrong at all, but others have several complaints. Like user Stych, who started the topic on the official Dell Community Forums (2) in the first place.
He reports random screen freezes, SD card not registering, apps not working, lower tolerance to the internal heat build, jerkiness when scrolling on the web and Facebook.
Other Venue tablet owners report not being able to mount the microSD card since the update. Particular to the Venue 8 is the fact that the battery will not charge past 60%, even if no issues were detected before the update.
However, out of all the complaints the most alarming problem seems to be that some tablets end up being bricked after the Android 4.4 KitKat update.
“Prior to update, my Venue never had a problem. Since the update, it has crashed multiple times, lost data, freezes, shuts down, goes into screen loops and shuts down just after displaying an error message com.android.systemui. Seriously, what went wrong,” says user conan1130.
Some users have tried performing a factory reset and reloaded everything, but the problems keep persisting. Dell representatives have yet to say something on the matter, but before they do, you might want to put off updating your Dell Venue 7 or 8 to Android 4.4.2 KitKat.
I updated a few hours ago. I guess only time will tell.
I had to send my Venue 8 back to Dell. My Venue was constantly freezing while playing games or just reading USA Today. Hopefully they can fix it as I really like the tablet.
I got my Venue back from Dell. The repair list states that the motherboard and screen has been replaced. So far, after playing with the Venue for about 2 hours, the screen hasn't frozen up. Hopefully, this is fixed and I shouldn't have any more issues.

Dell has been failure when it comes to software of any kind and that is the reason they flopped miserably in PHONE space, What I fail to understand about these giants that they dont seem to have read concept of CORE COMPETENCIES, Dell's core competence is HARDWARE and they should outsource software integration to a worthwhile partner. Build a pretty good hardware set partner with CYANOGENMOD to build ROM for them. Kitkat 4.4.2 has been horrible even for NEXUS users and that is why 4.4.3 and then 4.4.4 were released in quick succession by GOOGLE but companies like HTC, LG, SAMSUNG, SONY etc. did a very thorough testing and removed the BUGS as they are known to CUSTOMISE ANDROID heavily. Dell doesn't customise ANDROID too much hence they missed out correcting the bugs inherent in 4.4.2 and most surprisingly they dont seem to be bothered to release 4.4.4 quickly which has stabilised in its raw form pretty well. Michael Dell is master of past.

I personally did not experience a problem with battery drain. My tab updated out of the box and doing what I normally do such as controlling what apps update when and making sure none of them are waking it from sleep unnecessarily mine hardly drains at ALL when screen and wifi is off. I wake up with pretty much all the battery I went to sleep with. Dunno if it has to do with certain apps or the fact that it updated on a factory fresh out of box device or what but all has been well here.

Hi,
This is my first post so I do not know if it is in the right section.
I have an Android Phone (ZTE KIS V788 – Full spec: gsmarena.com /zte_kis_v788-4586.php)
It runs Android Gingerbread 2.3.6
It keeps turning off and restarts, it is basically not usable anymore.
What can I do to fix it?
And is there any way to update its software manually? (It has 256MB RAM, and 800MHz CPU)
Thanks!

Your issue is the device. No matter what you do to it, it will still act up. The issue is that the device doesn't even have enough ram to run the os properly. 256 mb of ram is just not gonna cut it.

I bet over the last month you have used it right? Meaning new apps, filling up database files in info? Phones like that are ok at best if left completely stock and maybe an app or two but they all sooner or later suffer the same thing. Mainly as they dont use an Official release version of android. Best advise I can give you is to keep it as clean stock as possible, Use cloud storage for pics and what not so you wont have them eating up space on the device.
You can get out of the soft bricked phase by try rebooting in fastboot menu. If that doesn't work you can try flashing the phones original files which will reset everything on your phone. Though, I recommend getting a new phone because, your still running gingerbread. That is an extremely old os as most newer devices are running lollipop and kitkat. If you don't plan on spending a lot of money on a phone, there are plenty of cheap phones out there. If you do manage to get out the bootloop than I wouldn't run any newer apps on it, as it will crash the phone.

I have always kept it stock, only installed Facebook and whatsapp.
This is a very weird issue, as the phone behaves normal when charging and does not randomly turn off.
I downloaded an app that checks the battery health, and it says that the battery is good.
I also noticed that when the phone turns off and I switch it back on then the battery is completely drained – for example I have it at 100% charge and after the random restart it shows only 9%.

To flash the phones original files, you will need to look up a video either on YouTube or find another website with informative directions. Basically, you will need fastboot files and roms/ img files to revert your phone. You will need a computer and usb cable for this. Go to YouTube and search how to fix a bootloop or how to fix a bricked/soft bricked phone. Best of luck.

Sounds like your battery is one of two things. 1. Its going bad. (Many reasons why the app is tell you its fine, Thats 2) 2. The battery is a fake and there is software that was changed to hide this. A common practice in some places in the world. The reason it is only now failing "could" be that it is starting to die but the software is still set to show you its good.
The fact that it works fine when it is plugged in would support those theories.
You could try reflashing the files as suggested, but do yourself a favor and DO NOT use some youtube video. At least not before reading up. The issue with youtube videos is that if something goes wrong then you are stuck even worse with no idea what to do. Then you will find yourself right back here.
