If you read my post again, you will see that I did not use "format all". I used "firmware upgrade" to upgrade from 6.0 to 7.0, and I lost IMEI. However rauliordache appeared to say that he had upgraded several times using "firmware upgrade" without affecting IMEI. I was just curious if there's any misunderstanding hence the request for clarification. Hopefully he will soon.

BTW your post suggests that you have done it too (upgrade roms with different partition structure using "firmware upgrade" without losing IMEI). Is that correct? Your confirmation would just be as good as rauliordache's. If it works for you or rauliordache but not me, maybe it's just something with my configuration.

Yap i'm using SP Flash Tool since 2015, flashed a lot of MTK devices and never lost IMEI because i never used "format all".

Back in 2015 when i started, there was no such information on the net and a lot of ppl suggested to use it. But i had the luck of meeting superdragonpt, a great dev for MTK devices.

He's also member of MAD, a dev team for MTK. You can find the most information about flashing on the Jiayu S3 Thread here on XDA.
[Android Q&A, Help & Troubleshooting] rauliordache:
Can confirm again: flashing several times the 7.0 ROM, then back to 6 (5.1 in fact), then back to 7 ... without any problems with IMEI.

I got some GPS problems ... in some online apps. But I think that this is due to the firmware/hardware, not from flashing ROMs. BTW, have anyone encountered same problem (with GPS)?

I've just used that. Now tablet reboots and then force closes system ui. = unusable tablet.

Have to check out now about how to disabling the module again during boot or disabling xposed to disable the module.

Since the tablet is in use at my parents and I'm only visiting for birthdays and such, I have to think harder how it was done and where I kept the recovery.

Thanks. Yes, I remember you posted that about the app. I'll check it out next time I visit my parents.

But since I told my father to force close apps when they lag too much (with long press back arrow - courtesy to gravity box), I can imagine it will always force close that app too.

HI all, I've just come back to this forum, and found your question haseka, regarding the possibility of obtaining a glass screen protector for your Voyo Q101.

As a matter of fact I have recently obtained a "Tempered Glass screen protector" for my Voyo Q101 from Banggood, but have not fitted it yet.

The one which I bought is also sold as the correct one for another model Voyo tablet also, and is the correct length for the Q101, but is approximately 2mm too narrow, so leaves a narrow strip at the top or bottom of the screen not covered, so take this into consideration if ordering from any source..

I hope this helps in your search

Hi [MENTION=9436463]donhe7[/MENTION],

thanks for your reply.

I don't think that the small impreciseness will be a Problem.

The protector you bought: is it in fact tempered Glas?

Can you tell me its article numbet at banggood?

PS: does anyone have a recommendation for a replacement battery?

It seems that mine has "gone belly up"

A few weeks ago I had an oil coloured spot in the centre of my tablet. Just right there where the battery is located.

I guess it was blown up so that it pushed against the LCD screen which caused the oil like spot.

At that time it battery life was about 10 minutes.

Now the spot is gone (i suppose the battery isn't inflated anymore) but the battery doesn't even last for a 1/2 minute.

Right now I can only use the tablet when it is connected to the charger. So think it is time for a new one.

I think I'll write to Gearbest, where I bought the tablet and wait for their answer before I open the tablet. (cause of warantee).

But I'm not very optimistic that they will be willing to help.

So basically I'm lookink out for replacement batteries in advance

Re: : A new cheap China tablet: "Voyo Q101 4G" a.k.a. "Teclast 98" 2GB/32GB octa w/ L

Hi there haseka, I must apologise for the delay in responding to your latest post, but have been a little pre-occupied of late and only just got back to the forum.

I'm afraid the Item No: 1266795 given in my reference to the screen protector does not bring up any response resembling the " Tempered Glass Screen Protector for VOYO Q101 VOYO I8 Pro Binai G 10 Mini10 Tablet ", but if you copy and paste that description into the "Search Field" on the Banggood webpage it should bring up the sought after item.

I am unable to verify whether the item is, in fact, "Tempered Glass", but it is definitely glass, not plastic, as it cannot stand flexing during transport, and I would suggest that you ask that the item be securely packed when you place your order to avoid disappointment.

Best of luck in your search for a replacement battery for your Voyo, let us know how it all goes

I have been looking at Aliexpress for a "lipo battery 5000mAh 3.8v suit Voyo Q101" and several batteries were listed, a number of them 3.7 volts 6000mAh.

If you have opened your Voyo and can see the battery, then you should be able to see the battery number stamped thereon, and possibly match it with one or more of that voltage and size, from what I have seen on listed lipo batteries, the first two digits of the model number stand for the package thickness, the next two digits are one dimension, (say 90), (mm), and the last three digits appear to stand for the other dimension, (in this case, say 130, or 140), also meaning, I believe, 130 or 140, (mm), or so it would seem, the voltage being assumed to be 3.7volts unless otherwise shown or quoted, the other digits being as I stated, so if you decide to go through Aliexpress, these factors could be helpful in your search

Again, best of luck

Used the tablet with no problems for some time. Than I did a factory reset. After that it just boots TWRP.

Mh, I tried to revert to my last TWRP backup - nothing changed.

Than I tried to flash all partitions that I have saved at the beginning. Now it is even worse.

It just boots into blue Voyo screen.

I i press vol+ while booting I can select to recovery (which ends in a "no command"), fastboot or normal boot - where nothing happen.

I hope I can somehow go back to stock .... Help! But Downloadlink is down at Voyo ?!?

To load the ROM you need to use SP Flash Tools

I own a VOYO Q101 4G and by error i flashed a wrong firmware and now the tablet is bricked. i've tried with many firmwares but anything it's correct. If i try to download the firmware from the voyo site say that not exists. My Voyo has a stick inside with the text "KT109_V30_5M_D3015_2+32_51PIN_20171101", I suppose that is the firmware version.

Please help me. I need the tablet and now is only a brick.

[Android Q&A, Help & Troubleshooting] Pxoeb6mU:
For anyone worried about the tablet not shutting down reliably on low voltage, 3C Toobox Pro ( https://play.google.com/store/apps/details?id=ccc71.at ) [which I consider essential for any rooted device anyway] allows you to define "Watchers" (under Device Manager) that can perform tasks when certain conditions are met.

You can use that to define a "mV <= 3450" watcher with a task of "shutdown". (And a mV <= 3500 showing a notification, to give you early warning).

EDIT: combine the "mV <= ..." condition with plug state = unplugged. This prevents the tablet from shutting down again right away if you turn it on after plugging it in, but the battery voltage is still below the threshold...

This ensures that the tablet gracefully shuts down on low voltage, independently of how correct the battery% is and what android does on it's own.

[MENTION=1509930]kerouac82[/MENTION]:

ouch, I wish I could help.

Had you reported this earlier, I would have refrained from this procedure myself, as this is the very nightmare I was afraid of myself.

But in my case - doing the same - I was successful and could back up all partitions (TWRP started on its own after the installation, no 'ADB' calls needed).

Hopefully someboy with more knowledge will show a path to escape that boot loop. So we all can learn to tame this weird thing.

In the meantme I found out that even the advertised CPU speed is a lie: the governors are set to 1.3GHz max (like on the Onda), and the device will never exceed this limit in runtime (checked 3C Process tools, in 'performance' mode, and live CPU monitors over days).

So here we have a tablet that is sold with an entire list of blatant specification lies:

- CPU speed is just 1.3GHz, not 1.5GHz

- Android is just 5.1, not 6.0

- battery is just 4000mAh, not 5000mAh

Most likely these deficiencies apply to the twin model Teclast Tpad 98 4G as well.

I will now go after Gearbest and report them to the Chinese trade and consumer authorities, as they ARE aware of the facts and do nothing about it. Selling with so many false claims is criminal IMHO. Many owners would probably NOT have chosen this cheap thing if the poor specifications were known upfront. This is consumer fraud by all means.

This tablet should no longer be sold, at least not with false specs.

To protect future customers from being fooled by deceiving Chinese companies and vendors.

Slapping an updated Android on it will only solve one of the many hardware deficiencies, and may indeed make no real sense anymore.
[Android Q&A, Help & Troubleshooting] mw210461:
For owners wondering about the Chinese boot menu (when pressing Vol- & Power during the start): here are the translations, thanks to my Chinese buddy

1. factory mode

2. automatic test

3. manual test

4. single test

5. test report

6. adjustment test item

7. erase eMMC

8. version information

9. reboot mobile phone

I will try to get translations for submenus as well, out of curiosity about test modes and functions.

Line item 7 may be the 'factory reset' so be careful when playing with this Chinese menu!
[Android Q&A, Help & Troubleshooting] Pxoeb6mU:
What happens if you turn on the tablet by pressing (and holding) Vol- + Power?

Flashing the recovery should not have in any way affected your boot or system partition (you flashed the file into *recovery* not kernel, or boot or whatever else flashify lets you choose, right?).

And on my two tablets, flashing into recovery did NOT affect whatever boots when I start the tablet with Vol- + Power, I still get that chinese menu when I use that and have to use adb reboot recovery from that menu to boot into TWRP.

EDIT:

Haven't done this myself because I didn't have a need to so far, but the tool to use together with that zip file you downloaded seems to be:

https://spflashtool.com/

and based on the description I've read, after you've got that setup and running correctly, you are supposed to connect the (powered off!) device via USB and it's supposed to boot into a mode where it will communicate with that tool without further action on your part.

(also, in case you haven't noticed it yet, the tiny hole on the side of the tablet where the power and vol buttons are is a hardware reset switch that you can poke with thin wire, in case holding the power button doesn't work for you to interrupt the bootloop and get the tablet turned off)

EDIT2: again, not done it myself, but that scatter file inside that zip should also allow people to flash TWRP recovery without first having to root and using flashify
[Android Q&A, Help & Troubleshooting] kerouac82:
When i m holding Vol- + Power, nothing happens. Bootloop the mediatek logo every 5-10 seconds. I don t remember, i have installed the Flashify app , chosen the the img File and flashify ask me for reboot, then bootloop begans. Usb on Pc ,with every boot is connected and 5 seconds later disconnected. I will try later again, if there is a way to flash the Firmware from voyo. But if someone has an idea......
[Android Q&A, Help & Troubleshooting] Pxoeb6mU:
What do you mean "nothing happens". If nothing happened then your device would be powered off and remain powered off.

Obviously you first need to power of the tablet (use the reset switch) or are you planing to let it loop till the power runs out?

Once the tablet is powered off, and assuming the battery isn't empty yet, pressing and holding Vol- + Power should at a minimum result in the tablet turning on, which is definitely more than "nothing", and should optimally boot you into that chinese boot menu, from which you can then use adb reboot recovery to get into the TWRP assuming you flashed it correctly.
[Android Q&A, Help & Troubleshooting] kerouac82:
The Screen is off at the moment, because i had used the reset button (the only way to turn it off) as you mentioned . But when I start the Tablet it goes directly into bootloop and the comination with vol- + power didn´t work. The chinese menu did not start.
[Android Q&A, Help & Troubleshooting] Pxoeb6mU:
So the tablet is off. You then first press and hold Vol-, and then press hold Power (while still holding Vol-), and you keep holding them both, then the tablet reboots after a bit (while still holding the buttons) instead of going into that chinese menu?

And assuming that's the case, once you use the reset button again, if you start the tablet by just holding power, it also goes into a loop?

Are you sure in flashify you clicked "Recovery image" and not "Boot image" under Flash?

The above behavior is something I could only imagine if you ended up flashing TWRP as boot image (where it does NOT belong), and in that case your only chance to restore the tablet is using the flashtool and the zip you downloaded to reflash a working boot image.

The boot loop shouldn't affect your ability to do that, as you leave the tablet turned off till the flash tool is setup, and then just turn the tablet on by plugging in the USB cable, which should then result in the tablet booting into a special mode that does not involve the mangled boot image.

Well, in this case GearBest is the vendor and Voyo the manufacturer/supplier. It's not as if GearBest is just a marketplace like ebay that Voyo is selling through. And in this case GearBest is definitely the party responsible for ensuring that the product they sell matches the description under which they advertise it.

---------- Post added at 04:32 PM ---------- Previous post was at 04:28 PM ----------

Sorry, I don't have an original system image, as in my case (KingRoot, Flashify) the system partition was already modified by the time I could make a backup (once TWRP can start).

The fact that you can't directly flash the provided zip without modification to the checksum would indicate that there is something wrong with that zip, maybe contact voyo and point that out?
