[Android Q&A, Help & Troubleshooting] mc_seem:
As we learned the hard way, they are two display panels for Voyo (samsung vs. huawei). One is incompatible : you'd get flicker and GPU issues.

I don't know that's the display panel type on your Teclast. If you have your original stock rom + scatter file and know of a way to enter SP Flash

mode, even if you mess it up, it seems like it's usually recoverable via SP Flash. There are couple partitions (nvdata, for example), you'd need

to backup.. just in case..

But fundamentally these two tablets are based off the same MediaTek board alps k109 .. although more recent tablets with 7.0 have a platform

name "joya_sz" instead of k109.. I don't know if it matters. What could be different between various flavors is camera sensor type & display panel

type, plus modem.. the 7.0 dump posted here is from a 4G device.

If I had both tablets, I could've probably cooked a universal rom that works on both panels.

Thanks, i don't know what is my panel. How can i do? My tablet is 4g version. Is there a guide to install voyo rom?

Hi, explain me in detail how to back up?

I have the factory running Android 6 (5.1) fake Voyo q101.

Thx

Oh my god!!! Thank you! Now I have android 7.0 and also my tablet get more speed on video frame! For now is perfect! Thankssss!
[Android Q&A, Help & Troubleshooting] rauliordache:
Next week I will also update my (fake) Android 6.0 (which is 5.1/API 22) to Android 7.0 from mc_seem. I have Samsung display type.

BTW, any problems with IMEI ? When using the same IMEI (with mc_seem), the tab will detect at the first Internet connection, and it will block your Phone cap ?

[MENTION=1528995]mc_seem[/MENTION], I also recommend a stock recovery back-up (and afterthat maybe flashing the custom recovery TWRP). BECAUSE, if something happens when flashing the new Android 7.0 (and the booting into any OS will fail), you wont be able to use SP Flash Tool. (instead, you will be able to boot into the TWRP recovery, flashing then the ,,old,, OS).

I will try to have multiple backups (using multiple tools). But, TWRP I think is the first option (before the instructions told by mc_seem - Thanks !!! ):laugh:
[Android Q&A, Help & Troubleshooting] mc_seem:
Yeah, I might be wrong, but the boot-up sequence is preloader -- little kernel (lk.bin , that contains all the fastboot functionality as well as ability to switch to SP Flash mode) -- then either boot or recovery, depending on in-ram flag for the previous reset reason. On my tablet I usually get the SP Flash mode on every time before anything shows up on screen. But indeed, if you have fully functional TWRP backup AND preloader + lk.bin (fastboot), it's possible to boot TWRP using fastboot boot TWRP-recovery.img then recover all partitions from there.. either / or, either via SP Flash OR via TWRP... worst case I had when I soft-bricked mine while experimenting with rooting my 1st Voyo tablet - I had to get the SP Flash tool and stock "fake 7" firmware from Voyo, and get it back that way because silly me did not back up the partitions for the 1st time. Full backup via TWRP recovery would work too. Flashify is another method. 6.0 is easily rootable with KingRoot, for example, (which I always prefer overwriting by SuperSU immediately after.. no hard feelings, but I do not like the AdWare that comes with KingRoot).. then Flashify... I read some anecdotal evidence of folks saying that somehow they do not get SP Flash mode by default after Power-On, but somehow it always works on mine, even when I soft-bricked mine badly - SP Flash Tools helped to recover.. it is relatively hard to hard-brick this thing, but very easy to lose your nvram for good..

Sorry, I'm being lazy to check the IMEI business, but since we kinda have full root or at least ability to mod the system partition (I previously posted up there below a boot image that turns dm-verity off), as well as customize boot.img - it should be relatively easy to soft-patch the IMEI. as well as serial number.. I'll look into that later.

This anecdotal evidence is due to people "thinking" that they have installed the MTK-bootloader mode drivers properly :D :silly:

[Android Q&A, Help & Troubleshooting] chan200606:
Hi mc_seem, I have just flashed your rom dump, then Jemmini's TWRP and SuperSU, and now I have rooted 7.0 on my Q101. However I notice that the SIMs are no longer working. First check indicates the IMEI's have both gone blank, and the normal methods to re-create them (Engineering mode then write to CDS-Radio info) do not work as the required fields (CDS info-Radio info) cannot be found.

I note that when I last flashed the "7.0 Samsung" rom on myvoyo.com to recover my soft bricked tablet, I also lost the IMEIs. I was however able to rewrite the IMEIs through Engineering Mode - Connectivity - CDS info - Radio info. This time however this does not work as the CDS info tab no longer exists.

Comparing the files in your rom dump with the roms on myvoyo.com, I see that yours include more files (28 files cf 15). The extra files include nvram.bin and nvdata.img which are not in the myvoyo roms. I am wondering maybe some of these extra files are corrupted somehow and by flashing them I have lost my original ones too? Can I ask you (and any others running 7.0) to re-dump the files so I can try again?
[Android Q&A, Help & Troubleshooting] mc_seem:
Assuming the SP Flash tool works as it should, it should not reflash these partitions... These should be unchecked by default.. otherwise - make sure that you manually uncheck these. These partitions contain factory data that is specific to your device. I'll take a look at where IMEI is stored and how to patch this properly.. Even if you lost your nvram, this should be recoverable. Just need to find where. The data is stored. I have two tablets, one good, and one that I bricked and wiped and downgraded to 6.0, then upgraded back to 7.0.. I'll try to do the nvram dump from the good one and find where the IMEI is stored.
[Android Q&A, Help & Troubleshooting] chan200606:
Thanks in advance. My tablet is basically in the same situation as your older one - it arrived only yesterday as 7.0, got soft bricked when I played with the wrong twrp, revived by flashing to 6.0 from myvoyo, and finally upgraded back to your 7.0 when I found this thread this morning. So if you can get IMEI in your old tablet to work, the same should then work for me. :)

I got my voyo with android 7.0 yesterday.

Can somebody tell me, what is the recommended way to do a full backup on first step and after that root the tablet?

I read all of this thread, but i still don´t know, which manual is for 6.0 and which one for 7.0 and how to backup all as first step.

If i first install twrp, then i can backup, but i want to backup the system in the step before twrp, so i get a factory fresh image as backup.

Maybe mc_seec could make a short description for new tablet owners including links to the needed files, then we could link this post to new users for make life easier.
[Android Q&A, Help & Troubleshooting] Bib_x:
I want to do the 4pda way with the files from jemini and the sp flash tool.

I have installed all on my windows 7 pc, drivers are installed.

But now i don´t know how i have to start? I have watched some videos on youtube and read some manulals, but it isn´t fully clear to me, how i have to set up sp flash tool. I loaded scatter file from jemini. And what is next step?

Do i have to make a backup of the whole tablet before this step or can i only do this with working twrp after i flashed twrp and supersu?

In the files from jemini@4pda are recovery.img and a folder called boot_recovery. Do i need boot_recovery-folder (with stock files inside) also or is this only for going back if something isn´t working with the new boot-image (backup for insurance?)?

So is this the right way:

1. Install sp flash tools and drivers like told in many turorials

2. open sp flash tool and load scatter file from jemini

3. set from "download only" to "firmware upgrade" <----- is this right?

---> where to set r/w like told in the manual?

---> where can i enter the path to the twrp recovery from jemini?

---> aftr flashing was successful, do i have to restart the tablet? How can i get into twrp on first run? Which buttons do i have to press?

---> after i´m in twrp, do i have to flash supersu and i´m finished? reboot and tablet is rooted?

There is another very important observation. After you make a backup, the program will create a scatter file MT6735.It will be necessary to replace this piece of text with this one:

More detailed instructions how to flash TWRP via SPFT:

1) Create a folder and copy there the corresponding scatter and recovery.

2) Starts SPFT and open scatter (from the folder that you created (Download only)).

3) Disconnect the tablet from the PC and clamp the buttons - ON + Vol(+) =>recovery(Select button - Vol(-)).

Do not forget about the VCOM driver.

Ok, i ordered a tempered glass from ali express.

I hope the feeling of the screen will get better with this. I now have the plastic screen cover on my voyo, which was already there when i got it. But the sliding is not very smooth.

Have you removed the original plastic screen protector? Will the feeling get better without this? I don´t want to remove it, because the screen is no gorilla glas and so i will get scratches very easy. I will wait until my tempered glass arrives and then i will test without the plastic screen protector.

xposed for Android 7.0 is working with the voyo? I rooted mine today and installed titanium backup to freeze all unnecessary bulk software.

Nice to hear another user gaining twrp and root successfully. Would you mind to give me a copy of the folder \vendor\priv-app\CDS_INFO? Through some careless act on my part, I have lost IMEI and can't rewrite these back as I'm missing the CDsInfo tab in engineering mode. I'm hoping that reinstalling the apk in that folder maybe I can get back there CDsinfo tab.

---------- Post added at 02:13 AM ---------- Previous post was at 01:53 AM ----------

My feeling is that fastboot is easier and more flexible. Once you have the minimal adb/fastboot setup and the tablet in fastboot mode and connected to a PC, just type in the PC "fastboot flash recovery <recovery file name>" to flash the recovery.

And if you want to be safer, you can instead type "fastboot boot <recovery file name>" to reboot the tablet with the new recovery, *without* permanently flashing the new recovery. Hence you can test to see if the new recovery actually works on your device first, and even backing up the whole tablet including the original recovery while with the temporary twrp running. Or you could install SuperSU under this temporary TWRP, hence getting root without overwriting the stock recovery.

The spft way, which is the official way, does not allow running TWRP in a temporary way. By the way to use spft you don't need to clamp special buttons. Just set the program up with a truck against the partitions you want to write (e.g. just the recovery), click the download button, power off the tablet (hold the power button until it asks if you want to power off and say yes), then connect the tablet to the USB port. The PC will "wake" the tablet to the right state and flash it.

If you are a lazy ass (like me), then the choice is in favor of SPFT. Well, I don `t know, always flash through SPFT there were no problems. To flash through Fastboot, you need to perform many actions. At MTK I'm too lazy.

[Android Q&A, Help & Troubleshooting] vertycall:
Use the pinpoint hole near the volume buttons to bring device in recovery mode. Windoze should then recognize it properly in order to run MTK tools to flash your desired firmware. At least that was the solution in my case. Hope it helps you too.

Nope .... but:

1. I've a TWRP full system back-up after flashing the VOYO_..._TWRP3.1.1 recovery image (after a back-up of the stock ,,chinesse" recovery). This is the good point.

2. I also want to run MTK Tool + SPFT in order to do another back-up (just in case), and also flashing the 7.0 firmware from mc_seem (scatter based). Unfortunately, MTK Tool + Windows 10 != love ...

[MENTION=6328140]vertycall[/MENTION], you are right! MTK Tool recognises the device just when it's in recovery mode. Strange...

By the way, I cannot create the scatter file ... and something is strange with this MTK Tool "outlook"....

To sum up, in MTK Tools:

- when it's in the chinesse recovery: no device detected

- when it's in the system (normal boot): no device detected

- when it's in TWRP recovery: device detected, but limited access (cannot create scatter file, no IMEI info, etc.)

By the way, I have read that I need a SDCARD inside the device before running MTKDroid? Is this true?

After updating the ADB inside the MTKDroid, I can run MTKDroid but with this error: --- TotalBytesPerChunk Not Found. Set default Page/Spare (last image)

There is a problem with the firmware. On 4pda forum, 3 of 4 users of Voyo API24/7.0 have this problem. Linear discharge from 100-50%, and then a gap from 50%-15%-0% in 2 minutes.

Use a Voltage monitor for monitoring the battery. 4-4.1V means ,,near" 100% and 3.4V means "around" 5%.

I got my Q101 2 days ago. Most things working -- regular cam (not one facing user -- have not tried it), micro SD, OnTheGo cable, charger (Euro + plug as well as local cheapy), wifi, various apps.

However, today tried to see what Canadian cell companies had a SIM for it. None seem to be recognized. I suspect that there is a firmware issue. Had a local techie have a look and he doesn't see anything obviously wrong with slot. Moreover, the SD is working, which indicates at least a part of that module is functional.

Am reluctant to arrange to send it back. Probably a never-never proposition, especially if I'm right about firmware. However, opinions welcome as to what I might try.

I am confused about the battery of Q101. Once they claimed 5000 (official) or 6500mAh (gearbest), others found it is just 4000.

My best advice is to do some research on YouTube before making up your mind. The P10 is available for 99$ via TechTablet's review https://www.youtube.com/watch?v=Wo1TPwo0ECQ

I bought the Onda V10 4G (mtk6753/2gb ram/Android 7), but in hindsight I should have bought the P10. The build quality is way better, but the Onda V10 4G is still a nice tablet and has TWRP available. Not sure P10 will get TWRP due to the Rockchip SoC, but I could be wrong of course.

I would advise against Rockchip. By far worst support for the developers.
[Android Q&A, Help & Troubleshooting] BiggestRetardEver:
I've had the Q101 for a few months now, and it's a decent tablet for the price. I have the same battery issues (rapid loss once it hit 70%), but since it's used as a mounted bedside media tablet only and continuously plugged in, it's a non-issue for me. The screen is pretty decent, with warm colours (my preference) and performance is fine given my lowered expectations. Even though it states a 64 GB SD card limit, my Samsung EVO 128 works fine.

In addition to the battery issue, the bluetooth performance is quite bad. While range is okay, recognition and lock-on are poor. I have my headphones plugged in to the jack, so also not a big deal.

For what I'm getting out of it, it's a fair value.

I also have the Teclast T98 Octacore as a backup, and can conform that they're not identical clones, even though they share the Bluetooth issue. The Teclast also drops the WiFi connection often. Screens about the same, slightly different android settings, similar but not identical sim/SD card slots (also works fine with 128 SD card).

I will eventually move to the Teclast Master T10 as my bedside unit as the prices drop, but all good for now.

Samsung Tab S 8.4 LTE: Still my daily driver. Best screen ever.
