Subsequent tries have "partition does not exist" error (same when using "system" or "system_a", or when using Derpfest image). It was the same yesterday - started with "Too many links", followed by "No such file or directory", and then all the following tries reported "partition does not exist".

(If I try flashing boot or vbmeta from stock, they go through just fine.)

These 2 days I used a little more the tablet and I notice a big issues. Screen touched alone near the down area and it's very annoying! Still I don't understand why happen this. I am with the latest official firmware. Maybe the original screen film make it happen with my sweaty fingers? Really I don't know.
[Upgrading, Modifying and Unlocking] jtrakx:
Hmm. I've never encountered those errors before. Are you sure your GSI image files are not corrupt? Normally the size of *.img exceeds 3GB. Otherwise, the image file you're using is still compressed and not yet ready for flashing.

I recommend that you flash again the stock firmware and repeat the whole process of unlocking bootloader.
[Upgrading, Modifying and Unlocking] jtrakx:
I am not a big fan of screen protectors. It can reduce screen clarity and touch sensitivity. That's the first thing I got rid of after unboxing the tab.
[Upgrading, Modifying and Unlocking] Neuromancer:
Successful this time. My bad... I had no idea that .xz extension was a compressed file (your comment on the file size was the key). 😬 Everything went smooth afterwards. Thanks again for all the help! 👏

So, I'm currently on lineage-20.0-20230815-UNOFFICIAL-arm64_bgN from https://sourceforge.net/projects/andyyan-gsi/files/lineage-20-td/

You mentioned you prefer DerpFest. Is this the correct source?

Any idea what's the point of Color menu in Settings/ Display? It's almost the same as in stock: a photo, and a single "radio button" underneath.
[Upgrading, Modifying and Unlocking] Neuromancer:
Same here (but then again, I'm careful, so I don't really need that). And then I also get rid of all the stickers the Chinese tablets and phones are so fond of.

Would you, please, tell us about the screen in the Alldocube iPlay 50 Mini?

I've been spoiled by my Alfawise Tab tablet with it's iPad screen and now that I have to replace it (broken screen, swollen battery) I can't really find any small tablet with a good screen, in the European market at least...

So, I'm keen on hearing about the Alldocube iPlay 50 Mini screen. Is it good?

Are the colors accurate?

Are the colors vibrant?

Does it have eye hurting IPS glow that stretches your eyes if you look as close as you would use your phone...?

How does it compare with the screen in your phone (which is probably very good)?

How is the contrast ratio? Deep blacks?

Can you watch a movie, in pitch dark, with top and bottom black bars without being distracting? The bigger the contrast ratio / deeper blacks the less gray are the top and bottom black bars in a dark environment

It it a clean screen, 'normal' screen or it has weird patterns? I've seen screens which had a weird prism-like effect put in tablets... hopefully it is not the case

Please allow me yet a question of a different topic: can you install google play services having the original ROM?

Thank you in advance!

[Upgrading, Modifying and Unlocking] jtrakx:
Great. Nice to hear you've done it.

I already tried several GSIs. Derpfest is one of the best so far. My personal issue with LOS is the CTS profile and limited customizability compared to Derpfest.

The link to Derpfest was posted in #77 by cobraxracing.
[Upgrading, Modifying and Unlocking] jtrakx:
No worries. We help each other here on the XDA forum.
[Upgrading, Modifying and Unlocking] Neuromancer:
I find the Mini's screen quite good, I'd say it's comparable to iPad, definitely the best among all the "less known" tablets I've been through. I can't answer about all the details you're looking for, maybe I can check some in the next days when I have more time, and get back to you.

In my opinion it's much better than the iPlay 50 Pro screen (which has a blueish tint, something I was hoping to fix with a custom ROM, but I have yet to find the tweaks). The Mini has warmer colors - I even installed iOS themed icons, and along with the new design, it kind of feels a bit like an iPad Mini.
[Upgrading, Modifying and Unlocking] Neuromancer:
I was actually hoping for more customizability in Lineage, but it doesn't seem that different from a random clean stock ROM with Simple Mobile Tools installed and bloatware uninstalled/disabled. It's been quite a few years since I was last doing this, and there was also more privacy-related tweaks back then.

So I guess I'll have to try several as well.

Does anyone know if it will be possible to unlock the bootloader for the NEW (as of this week) Alldocube iPlay 50 Mini PRO with the MediaTek G99 CPU? The iPlay 50 Mini has a Unisoc T606 - is there a way to unlock this?
[Upgrading, Modifying and Unlocking] antouaa:
I discovered after I bought iplay50pro another cheap Chinese tablet with the same CPU, RAM, ROM. The N-one Npad X. It's a little more expensive but have huge battery, 4 speakers and android 13. What do you believe is it worth or you still don't trust this brand?

Thank you for the great JOB and the assistance!!!!
[Upgrading, Modifying and Unlocking] HisokaRyodan:
Nobody knows until we have it in hand but I assume yes considering it’s the same as the Iplay50 Pro. However you do have to flash a patched boot and as of now AllDoCube hasn’t added the pro mini to the site. I should get mine sep5-12 I’ll report back as soon as I get it. At least on the boot loader front if the firmware hasn’t been posted
[Upgrading, Modifying and Unlocking] oaklandz:
Great, I'll probably upgrade to the mini pro from the mini. And, is it correct: there is no way yet to root the unisoc T606 mini? Or is there?
[Upgrading, Modifying and Unlocking] HisokaRyodan:
As far as I know no. It appears they have some other sort of lock in place. People have mentioned there being private keys that are needed but there hasn’t been a response from alldocube.

However they did state “unlock it just as you would any other t606 device” which leads me to believe they didn’t intentionally do anything to stop the unlock, it just kind of happened l.
[Upgrading, Modifying and Unlocking] jkd:
IHi, is there a procedure for iplay 50 (not Pro) ?
[Upgrading, Modifying and Unlocking] HisokaRyodan:
I have received the iplay50 Mini Pro! Everything looks great except there is def a weird thing with the vibration motor, it makes all kinds of noise it shouldnt. I turn that off so hopefully that doesnt effect anytthing else.

I was able to successfully unlock the bootloader on the iplay50 mini pro. Same procedure as the 50 Pro:

1. Turn on developermode

2. toggle OEM Unlock

3. adb reboot fastboot

4. fastboot flashing unlock

5. HIT VOLUME DOWN

*it says to hit volume up to unlock but volume up didn't do anything for me, i had to hit volume down (which says Auto.... does not unlock bootloader. but it did infact unlock it. I get a successful unlock message and it reboots in orange state and wiped as it should)

Now all i need is the boot.img from the stock firmware which doesn't appear to be posted at this moment. Once I get that I will install Derpfest and report back
[Upgrading, Modifying and Unlocking] HisokaRyodan:
Maybe I spoke too soon. I did try just flashing derpfest which should work even without a patched magisk, but nkw I am in a boot loop. Well more so it’s just on the alldocube logo. With no stock firmware I can’t recover so I’ll have to wait I guess
[Upgrading, Modifying and Unlocking] king-totti85:
oh this is such bad news for those who are welling to mod the tablet like me.

I will receive my device by end of the next week, kindly let me know if I can help with any thing like doing back up or dumping system partition.

may be you can go to recovery if accessible and try wiping data again, also try to flash other rom that is close to pure android.. eg pixel based roms

last option could be contacting alldocube or seller for the stock rom
[Upgrading, Modifying and Unlocking] Neuromancer:
Any idea what's the deal with iPlay 50 Pro Max? It's shown on Alldocube's website, but not available anywhere (their own "buy" link doesn't work).
[Upgrading, Modifying and Unlocking] rprr22:
I also bought an iPlay 50. Curious about this.
[Upgrading, Modifying and Unlocking] Kurosoul:
I had the same trouble with until I had a patched Boot.img that got me out of the bootloop.

Try using Kernelsu from here to help you boot properly since you don't have access to the firmware yet.

android12-5.10.136 img or android13-5.10.168 img should do it, I think.

Hope that helps you 👍
[Upgrading, Modifying and Unlocking] Kurosoul:
Check maybe you have an ad blocker stopping from loading the link?

I got this link from alldocube website when I click buy.

https://a.aliexpress.com/_mrsJgDG

Good size for me and dual speakers, that was only thing holding me from the iPlay 50 mini Pro being mono/one speaker only but the screen is definitely better than the Pro Max.
[Upgrading, Modifying and Unlocking] Kurosoul:
If anyone is interested, it's real easy to modify and make your own custom boot logo for this tablet or any that use the logo.bin file.

Trying to attach a screenshot but it's too big.
[Upgrading, Modifying and Unlocking] HisokaRyodan:
So you were able to boot to a GSI using the Mini Pro? What were the steps? Was it something like this:

1. Unlock bootloader in developer settings

2. Unlock via fastboot

3. Boot into fastboot and flash KernalSU: "fastboot boot android13-5.10.168.img"??

At that point it should be rooted? then

4. Flash GSI

does that sound about right? out of curiosity after using kernelSU can you use magisk modules?
[Upgrading, Modifying and Unlocking] Kurosoul:
Step 3. Fastboot reboot fastboot (to enter fastbootD menu) make sure it's fastbootd, not fastboot to unlock.

Then fastboot flash boot boot.img (android13-5.10.168.img) I always rename to make the name shorter, run into less problems and it works better.

Step 4. Flash whenever GSI you want to use.

Step 5. Reboot into recovery to wipe data/factory reset.

Step 6. Reboot and wait.

Hope you will find success 🤞
[Upgrading, Modifying and Unlocking] Neuromancer:
Yep, that was the link, I was able to open it at work, because at home I use heavy blacklisting. ;)

I can only speak for Mini regular and Pro regular, but yes, the sound on Mini is horrible (1 screechy speaker), however its screen is definitely better. Here's the side by side quick comparison - on the left is iPlay 50 Mini, on the right is iPlay 50 Pro. The Mini has a "calmer" tone, almost like an iPad or an iPhone, whereas the big one has a cold blueish hue (like most of the "el cheapo" tablets I've tried in the past), and no option to change it (night light or adjusting RGB don't really cut it).

Also, the brightness level can be set quite low (for use at an average room lighting) on Mini, but it has to be over 50% on iPlay 50 Pro to be able to see anything normally.

And still I have no clue as to what the point of "Colors" menu on iPlay 50 Pro is (in stock or Andy Yan's GSI), because there's just a set of photos there and one radio button without anything.
[Upgrading, Modifying and Unlocking] HisokaRyodan:
Has anyone got Viper4Android to work on the iPlay 50 Pro? I tried both Derpfest and PixelExperience and both get stuck on "Installing Magisk Module".

I have the same PixelExperience on my Samsung Tab 7a Lite, and it works so I don't think its rom related.
[Upgrading, Modifying and Unlocking] HisokaRyodan:
For anyone wondering, i tried installed KernalSU on the iPlay50 Pro and it didn't work. Just boot loops, wanted to try it out. I compiled my own boot.img using the instructions and made sure it was the correct kernal version, and still didn't work. I also tried using the premade flashers but that didn't work either. just my two cents for those who want to try it
[Upgrading, Modifying and Unlocking] HisokaRyodan:
Is it possible for you to dump your boot.img since you have root on GSI? I actually ordered a second one as I have no clue when Alldocube will upload the firmware and I don't want to mess it up since i really need a working tablet!
[Upgrading, Modifying and Unlocking] king-totti85:
I tried to flash many gsi roms in iplay 50 mini pro using DSU sideloader app instead of direct flashing.. all of them ends in bootloop.. tried YAAP, elexir, Superior OS 12L & 13.. no luck at all.. will keep trying others and report back if any of them works
[Upgrading, Modifying and Unlocking] HisokaRyodan:
did you flash kernelsu like kurosoul said? he was able to root it using kernelsu
[Upgrading, Modifying and Unlocking] king-totti85:
No.. will try to delay that for now.. l lost my beloved Lenovo legion y700 after root trial that went into the wrong way.. so I am trying to play safely.. at least for now
[Upgrading, Modifying and Unlocking] HisokaRyodan:
that sounds awful. can you sideload kernelsu using DSU-Sideloader? If it creates its own space and doesn't touch anything in play, shouldnt you be able to just flash the kernelsu.img and see if it boots? I have never used it just thinking aloud
[Upgrading, Modifying and Unlocking] king-totti85:
I am not expert also in DSU sideloader, but as far as I know it flashes the system partition only. however if you have a gsi with superuser privilege you should be able to dump boot partition in order to patch it using magisk(or kernelsu?)
[Upgrading, Modifying and Unlocking] king-totti85:
BTW still trying gsi roms.. Lineage also no luck.. I remembered that I didn't run the fastboot command for critical unlock, I know that it's required for flashing system images but don't believe that it is required for DSU sideloader, anyway will run the command and see
[Upgrading, Modifying and Unlocking] king-totti85:
all GSIs I tried are not working, even android 14, I think I need to disable verity to be able to boot gsi, if anyone knows how to disable verity and verification without having the original vbmeta kindly help
[Upgrading, Modifying and Unlocking] Neuromancer:
Today I moved on from Andy Yan GSI to Derpfest (DerpFest-13-Tango-2023.08.23). Indeed tons of customizations. Two or three menus in the Settings keep crashing (i.e. they don't open anything, just crash Settings app), but nothing critical.

What bugs me (but is solvable in the same way as with stock OSes) is that it's way too much Google-oriented for my taste...

BTW, is Android Auto not part of this release, or is it just my device?
[Upgrading, Modifying and Unlocking] Kurosoul:
So I'm trying to get my tablet back from my niece (was not paying attention) but I will post the boot imgs I currently have on the PC.

I'm also trying to get the stock firmware from the seller but it's a struggle.
[Upgrading, Modifying and Unlocking] king-totti85:
hi @Kurosoul

kindly can you upload the patched vbmeta.img for iplay 50 mini pro?

Also were you able to boot any Gsi rom in iplay 50 mini pro, either via direct flashing or DSU sideloader?
[Upgrading, Modifying and Unlocking] Kurosoul:
I never patched the vbmeta only the boot.

Right now so far Derpfest and Cherish OS, haven't tried any more since I'm still trying to get my tablet back from my niece.

I flash everything by fastboot so far for GSI, haven't tried anything else yet.
[Upgrading, Modifying and Unlocking] HisokaRyodan:
This is awesome thank you so much!

Which version of firmware is this boot from? I assume this is the boot.img that has the kernelsu on it, can you get a screenshot or picture of the kernelsu app so I can make sure the new mini pro I get has the same firmware as you?

Also, do you know what version of the firmware you were on? I don't know if flashing a different boot.img with kernelsu on it will cause a boot loop.

Anyway thank you!
[Upgrading, Modifying and Unlocking] Isaac™:
for those who have devices based on MediaTek and do not have official firmware from the manufacturer, you can try using the mtk client gui 2.0, all (I think) mediatek have a mode called "BROM" which is equivalent to an EDL, using the mtk gui 2.0 client You can do partition backups, I don't have an iplay50minipro so you need to find a way to get into "BROM" yourself

1st step: open the mtk client gui 2.0 (it will be in detection mode)

2nd step: hold the + - button and with the USB cable connected to the PC, quickly insert it into the tablet

Here are some combinations:

hold the + - button and lastly (hold the power button and quickly insert the usb)

just hold the button - and quickly connect the USB

or

Hold + and quickly connect USB
[Upgrading, Modifying and Unlocking] jtrakx:
If the Color menu is empty, you can adjust color temperature at the LiveDisplay menu. Just lower the blue color to 85-90%. It works for most GSIs. I already tried it.

There are some few GSIs that contains color adjustment in Colors menu. Unfortunately, in my favorite GSIs, the Color menu is empty.

IDK, but for me, the Iplay 50 Pro display seems to be descent enough. The color is not as "blue" and not as dull as the Samsung Tab A8 2022 display. My only gripe is the poor brightness level.
[Upgrading, Modifying and Unlocking] jtrakx:
Yes, I tried Viper4Android in Derpfest and PixelExperience Plus. The module works perfectly in KernelSU. So you're correct in saying that the problem is not GSI ROM-related.
[Upgrading, Modifying and Unlocking] jtrakx:
The KernelSU (latest version 0.67) works perfectly with Iplay50 Pro. The reason for boot loops is flashing the wrong version and kernel compression type. The Alldocube Iplay 50 Pro uses the GZ compression.

I've attached the files you need ready to use. Just flash the img file in boot partition and install the apk.
[Upgrading, Modifying and Unlocking] jtrakx:
For those Iplay 50 Pro owners interested in replacing the stock boot logo, here are the simple steps:

1. Download the Logo Builder ver 1.6 from this site:

https://xdaforums.com/t/changing-boot-logo-logo-bin-program.1953726/

(A big thanks to Ankadnikov)

2. Copy the stock Logo.bin from the extracted Iplay 50 Pro stock firmware and place it in the Logo Builder folder (for convenience).

3. Run the Logo Builder, create a new project, and load the stock Logo.bin.

The contents of stock logo.bin will be extracted in your selected project folder.

4. Using your favorite photo editor, edit these two files:

img1.png

img39.png

Keep in mind that these image files need to be at 2000x1200 resolution.

Note: You may edit the img1.png only and replace the img39.png with the one from img1.png

5. Press the "make" button in Logo Builder. The logo builder will create 2 files (a ZIP and a BIN) in your project folder. You only need the BIN file.

6. Flash the new logo.bin in bootloader mode aka fastboot mode (I tried it first in fasbootD, and it does not work):

fastboot erase logo

fastboot flash logo new_logo.bin (new_logo.bin = the filename of new logo.bin)

fastboot reboot

7. Enjoy your new logo.

I was trying this yesterday with iplay 50 mini pro before seeing your post, unfortunately it was giving error message "handshake failed", already tried volume buttons and power with volume buttons no luck, will try other combinations you mentioned but I am also suspecting that I have driver problem regarding mtk port deriver
[Upgrading, Modifying and Unlocking] jtrakx:
Unfortunately, the Derfest GSI builts are mainly stuffed with Google apps. So if you are not a big google fan, you may try other GSIs in BVN or BVS variants. If BVN or BVS is not available, you may try the BGN slim variant.

If you are planning to use the Android Auto feature, you may need to download it separately from the Play Store since not all GSI builds incorporate this app.

By the way, a new version of Derpfest GSI was already posted yesterday. You may want to try it.

If you intend to use third-party launchers (like Nova) you may want a GSI that can totally disable the Google transient taskbar. This taskbar was made for the stock launcher and only a few GSIs have the option to disable this. If I remember them all correctly these are:

Derpfest -- best implementation of taskbar deactivation

SparkOS -- buggy implementation due to conflict with navbar options but there's a workaround.

crDroid -- same with sparkOS.

Evolution X? -- same with sparkOS

I am currently using crDroid. I like it better than Derpfest. And I think I will stay with it for a while until the release of Android 14.
[Upgrading, Modifying and Unlocking] HisokaRyodan:
Thanks for this! I actually just used magisk to flash kernelsu and then removed magisk but this is great information.

How do you find out what compression type the boot.img is in?
[Upgrading, Modifying and Unlocking] king-totti85:
if you got your mini pro back kindly back up the boot partition and upload it here.. I think it would be much safer solution than trial and error method
