Any help?

Hello Lucas,

Yes you must unsold it before doing anything or your BIOS will be totally fried.

Check on youtube how you will do or visit a technical repair person and he could do it.

Good capacity yes but with no quick charge peformance, Thanks Bill and good night!

[Fouad]

how many normal charging hours while it’s poweroff and how many if charging while it’s on?

I had the tablet dead after a week of purchase and i saw it’s slow charging but not remember exactly how many hours it need to charge during poweroff and during operation?

Do you have dualboot version and is the original charger 2.5A or 3A you received?

[Fouad]

i would thanks you so much Bill for help and support, really appreciated! Now Tablet back to life!!! 😀

I soldering the +ve back but without Flux so it was hard to do. searched for the flux but didn’t find it around. bad soldering done but OK as it works for now.

I was measureing the voltage and it was around 2V and i monitoried it till reach 3.75 and power it on and wow it works! 😀 i found it’s 15% only, i used latest firmware that should have the shutdowns issue solved and it can go to 0% not 21% as in previous firmware.

I would thank you again! 🙂
update: in 3 hours it charges to additional 35% while to be total of 50% it’s poweredoff during charging and i only booted three times to see progress, means it could take 9 hours to full charge while it’s poweredoff! is this normal for first charge after firmware burning or it could be another issue in power circuit?

[Fouad]

I will need to good soldering the +ve as i have no flux then will try keep it in charge and see.
Thanks Bill for your Support.  Hope it will works at end..

in continue with driver grapped from online microsoft updating, i was able to erase, blank, write ,verify as per screenshot. but at end tablet not powering on, power led not blink with charger!
My issue is same one as yours, usb was inserted powered off tablet ,power it on, nothing appear in screen but usb was blinking after a minute i forced power off the tablet, power it again so nothing and power led blinked for seconds and then dead!!

so it’s not a corrupt BIOS here or what :(? and by the way picture ordination is show the wrong one in attached screenshot and i didn’t get your point on the related message.

i did that in windows 10 even i tried on a second windows 10 tablet and same thing, the driver shown unknown device in device manager.

for picture ordination, how could change image ordination?? the three options chosen as per pdf image but it shows the wrong ordination you mentioned, how could choose the right one?

and actually i don’t know why device manager show it as unknown device on both windows 10 machine!
and on win7 machine it shows as USB-EPP/I2C… CH341A and was able to update the unknown driver in this win7 device manager manually. but it can’t detect the chip here.

[Fouad]

I’m trying to reinstall the win7 driver on win7 and it says install failed. and the driver that was installed is the one detected by windows itself!, uninstalled it and reboot , try to install the win7 driver and same issue.
In window 10 the driver says it’s preinstalled successfully but programmer not connected..

Update: in win10 i let windows online update search for driver and it got it with same name in win7 in device manager! and now it’s connected but same thing, it can’t detect the chip! i really have no idea what’s going on..

is the windows online driver is okay? or must install the one we downloaded from here? which at end it is fake install in windows 10 as it shows unknown device in device manager? and initially driver failed in win7 but it’s got the driver from windows online update also!

[Fouad]

Yes choose it right.
all are well connected. not sure what issue is. i think i may cancel the writing now and start from scratch!

[Fouad]

So it’s fake writing now, is it safe to stop it?

yes i’m using v1.29 posted here. so what could be wrong here?

Hello Bill, thanks for your help, i installed the driver on win 10 however the program not showing it connected. i notice a bit different in the test clip and component. You could see the picture. And please advise if you have an idea or something wrong.. actually how could i ensure the tools i got are working properly and not faulty!. or it’s a driver issue?

I downloaded the old driver on win10 machine and copied the folder to win7.
Now programmer is connected, however when try to detect the ship it say detect fail. tried to reattach the clip and same!
i ignored that and click on empty and the percentage in bottom left running, after that tried blank but it said data is not null!
i opened the firmware .bin and doing write now and it’s 12% so fat and it’s very slow!! hope it will work …..

Hello,

Could you share the Driver to install in .zip package, I’m trying to download the .rar file shared by Chris but everytime it got blocked and removed via the antivirus and not able to disable it as it’s not allowed by corporate policy.

Another question please, could you clarify on how to attach the converter to the programmer, what do you mean of insert pin 1 closest to ZIF latch as i see in picture it’s already far from the latch?

I will receive the tools today. so may i got your answer especially for the driver package in zip format to install it on win 7. as i read it will not work on win 10 that’s why i’m using my corporate laptop win7.
