Could a genius with some time on there hands make TWRP for this device, its driving me insane, everything provided below.
Android 8.1
2GB RAM
Snapdragon 210
MSM8909
GPU Adreno 304
Times like these i wish i could follow a tutorial correctly.
Thanks in advance!
I had to archive the recovery as the IMG was over 8MB.

I know this reply is a little late... but have you tried twrp builder app? Search xda... got a working recovery for an obscure UMX budget phone... I have this tablet but I haven't bothered trying to do anything with it.
i have ported the Lenovo Tab 10 TB-X103F twrp to {TB-X104F}

what am i doing wrong
Interested in recovery for this tablet also. Any luck?

Hello Good People,
Is there a working TWRP for this tablet?
T.I.A.
Hello again,
Is there any working recovery for this tablet.
Its very very difficult to find a custom ROM.
Are people using LineageOS ?
T.I.A.
Joke title aside, I had an idea for getting unencrypted and thereby instantly mounting sdcard as internal storage.
The idea is simply going inti the fstab and simply changing the entry for /data into
Code:
/dev/block/mmcblk1p1
. This requires the sdcard to be freshly formatted I think (probably in either ext4 or f2fs)
Going even further, we could get back the internal storage and make it appear as an external sdcard, so it's not totally wasted. (In theory, maybe I'm overlooking something). For now, it's not in the modified fstab.
Only do this if you don't have anything to lose on the phone and on the sdcard
Here's the modified fstab. Would be interesting to see if someone could test it. Copy and paste the text in the spoiler into a new file called fstab.qcom (make sure to save in Linux line breaks if you're on Windows).
Make sure to make a backup of /system/vendor/etc/fstab.qcom before proceeding via adb pull or some other method.
Reboot to TWRP
Again, make sure you have backed up the file you're about to overwrite
Do adb push fstab.qcom /system/vendor/etc/
Reboot
See what happens
Spoiler
Code:
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK

Emmc memory is much faster than sd-cards and even more importantly it's much more failproof than the regular consumer grade sd-card. But if low on storage for apps, sure

Wel it wasn't intended to be a serious mod. I'm mostly just curious if it works and need a guinea pig as I can't afford wiping my phone right now ?

From this thread: https://forum.xda-developers.com/pr...velopment/aosp-10-0-quack-phh-treble-t3992559, the TrebleCheck app indicates we need an arm64 "a-only" ROM. The Palm Phone is running vendor version 8.1.
Step 1: Download Sugar. This thread: https://forum.xda-developers.com/android/general/release-root-palm-phone-t4021201, has everything you need to know about Sugar. I ran the upgrade once to download the full stock ROM (make a backup as described). Warning, this erases all of your data.
Step 2: Follow this guide: https://forum.xda-developers.com/android/general/guide-porting-twrp-source-t3843473, to build a TWRP for the Palm Phone without source. I used the latest TWRP for the Asus Nexus 7 2013 LTE as my base. From your Palm upgrade backup, the recovery image is the one that starts with 'R', about 36MB. Rename your new TWRP image to match the stock recovery and replace it similar to the rooting guide for replacing the boot image.
Update: snoopy20 has shared his TWRP image here: https://forum.xda-developers.com/showpost.php?p=82654073&postcount=26
Step 3: Extract the system image you downloaded and rename and replace the stock system image. It's the largest file in your Sugar device folder.
Step 4: Re-run the upgrade in Sugar with your replaced images in place.
Step 5: You're probably stuck in a boot loop. Press and hold the power button until you get into recovery, which is now TWRP. First, I formatted data. Then push or otherwise copy this zip to the device: https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389 and install it from TWRP. The stock configuration should be fine, i.e. don't worry about re-naming the zip. Note, do NOT use adb sideload, since that seems to wreck the zip installer's ability to use its own file name to configure itself.
Update: The Universal dm-verity zip may not always work, in particular on AOSP Android 10 images. In this case, you can use another Android device and Magisk Manager to patch the Palm boot image. Push the boot image from your Palm backup (described in Step 1) to the other Android device. It's the mbn file that starts with 'B'. I chose to rename it to boot.img for easier use. Than use Magisk Manager to patch it. Push the modified boot image back to the Palm (in TWRP) and use TWRP to Install->Image it.
Step 6: Reboot! Wipe data and cache for good measure, and you should be set!
All credit goes to the folks from the links above for creating the Treble system image, TWRP guide, and dm-verity script. Thanks to snoopy20 for his TWRP image.
Things that work so far:
* Almost everything
Doesn't work
* Soft key requires an app, such as Key Mapper, to use
* Screen auto brightness is missing
Can you post the TWRP you created?

Is it kosher to publicly post a TWRP created like this (i.e. not from source)?
Additionally, I'm not entirely confident I didn't screw something up, so I'm a little wary to risk everyone's device. Specifically, I do not know what would happen if you get caught in a boot loop and don't have a functioning recovery to boot into in order to restore...
Yeah you just write "Unofficial" or something in the title. Right now I'm happy to brick the Palm, I'm 99% of the way to dropping it but it would be fantastic if I can get a stock Android on it.
By the way do the restrictions, i.e wifi tethering, get applied by the Vendor package?

Hard for me to test since I don't have a supported SIM, but the tethering menu is available in Settings. You'll have to try it and let us know.
If you post the TWRP I'll do so. My biggest concern is if I **** up building it. I sent you a PM.

Just waiting for android file host to approve
I've attempted to repack but found:
1. Two fstab files are fstab.qcom and fstab.grouper, don't know if I should delete them but instructions seem to indicate I should.
2. Stock ramdisk folder doesn't have a fstab.* file to copy over.
I ended up with this twrp.fstab. Note the encryption part from /data is gone? Unsure if this is ok.

Just a big heads up, when trying to connect to the network today (Visible) I noticed that my IMEI was 0000.... I have never successfully connected the Palm phone and while the behavior now is consistent with my issues before, I can't say whether or not flashing the GSI as outlined here erased my IMEI.
Proceed with caution.
I'm not proceeding at all unless you post your twrp or verify the issues I've had creating it.
I read the IMEI is held on another partition, type 'efs'. I can't see Sugar killing it. More likely your fstab options aren't mounting it.

OK I've compared and I can't see anything major. The only thing you do have is a few more mount points which I've not had in mine (listed). Where are they from? I think mounting the sdcard (modem firmware) is a bad idea so I'm going to skip that.
/sbl1 emmc /dev/block/bootdevice/by-name/sbl1
#/sbl2 emmc /dev/block/bootdevice/by-name/sbl2

So, I have twrp installed, and a fast bootloop almost instantly on start. I haven't been able to solve it thus far. I can get into twrp which is something though.

Sounds similar to me. Did you flash the new system as well? If so, this is when you use TWRP to flash the zip to disable dm-verity.
I did, then the dm-verity but with no success. Assuming /system was corrupt or wrong I've deleted it. I'm now trying to work out how to flash the system.img without fastboot (which I don't have).
So far dd is ending up with a corrupt partition and twrp insists on a zip for system flash. Trying to figure out how to convert it.

Actually you said you tried 10 unsuccessfully, so how did you then flash the v8 image?

I'm assuming the 2nd link down in OP (github).
This is exciting!
Anytime I got stuck, from TWRP I used
Code:
adb reboot edl
then I used Sugar to reflash everything all over again.
Phew, I didn't know about that one. I'll try again.
You can't flash an img from TWRP, there's no boot partition to enter fastboot mode.
I'd originally downloaded the nogapps without su and added Magisk.zip after, this caused an instant bootloop. The one with build in gapps+su works. It's possible to disable all gapps and related services except GoogleOne (I installed OpenLauncher into /system/app then removed GoogleOne by force). After this "Google" can be removed and all notifications about Google Services end.
I recommend you take down the twrp and remove the line which mounts the firmware partition as sdcard in case this is what wiped your IMEI. I build my own without this line and IMEI survived.

Heya guys!
So I've been busy making a TWRP recovery image for my unlocked chinese tablet (a Deejoy q728) that I bought from Amazon. It's a reaaaaally generic one with literally no firmware available over the entirety of the webs(yes I followed every tutorial you could think of that explains how to find firmware, believe me *sigh*).
Now I've gotten TWRP 2.3.6 to actually boot. I used the recovery img from another tablet with almost the same hardware(Concord HS or something) as a base and brought the necessary files into a TWRP 2.6.3 for the AllWinner A23 SoC. with Android Image Kitchen. The steps I took are from this post on DroidWin. It boots but I am encountering the following(major) problems.
1. Even though it displays in landscape, the touch screen seems to think it's in portrait.
2. Partitions just can't be found whatsoever. I think this might have to do with the fact that I don't know too much about fstab.
3. Adbd doesn't work.
By the by, I also edited the fstab files so that they contain the specific partition info of my tablet, not the Concord, as the Concord has several partitions that simply don't exist on mine. Code for twrp.fstab and recovery.fstab down below:
Code:
twrp.fstab:

Edit: The main reason I really want this to end up working is because there are a ton of cheap allwinner a50 tablets and most of them(at least mine) are bootloader unlockable. Add Magisk to these babies and voila! Ya got a cheap device that you can theme to your hearts content. Toying around with tech has always been my thing haha.
So if anyone has any tips for me to get a sorta head start on this, I would really appreciate it!

Heya guys!
So I've been busy making a TWRP recovery image for my unlocked chinese tablet (a Deejoy q728) that I bought from Amazon. It's a reaaaaally generic one with literally no firmware available over the entirety of the webs(yes I followed every tutorial you could think of that explains how to find firmware, believe me *sigh*).
Now I've gotten TWRP 2.3.6 to actually boot. I used the recovery img from another tablet with almost the same hardware(Concord HS or something) as a base and brought the necessary files into a TWRP 2.6.3 for the AllWinner A23 SoC. with Android Image Kitchen. The steps I took are from this post on DroidWin. It boots but I am encountering the following(major) problems.
1. Even though it displays in landscape, the touch screen seems to think it's in portrait.
2. Partitions just can't be found whatsoever. I think this might have to do with the fact that I don't know too much about fstab.
3. Adbd doesn't work.
By the by, I also edited the fstab files so that they contain the specific partition info of my tablet, not the Concord, as the Concord has several partitions that simply don't exist on mine. Code for twrp.fstab and recovery.fstab down below:
Code:
twrp.fstab:
/boot emmc /dev/block/by-name/boot
/recovery emmc /dev/block/by-name/recovery
/system ext4 /dev/block/by-name/system
/data ext4 /dev/block/by-name/UDISK flags=encryptable=/dev/block/by-name/metadata
/cache ext4 /dev/block/by-name/cache
/misc emmc /dev/block/by-name/misc
/external_sd vfat /dev/block/mmcblk1p1 flags=removable;storage;display="SDCARD"
/usb-otg auto /dev/block/sda1 flags=removable;storage;display="USB-OTG"
recovery.fstab:
# Android fstab file.
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK
#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>

I realize this port is now months old, but I did want to ask how your TWRP port worked out? I'm presently working on Allwinner-a50 and Allwinner-100 tablet projects.

Welllll I have no idea how I did it, but I got it to boot. Touch screen drivers functioned overall but while being horizontal, the touch screen responded as if in portrait, so I literally ended up measuring where what button would be on the touch screen compared what was actually displayed. I eventually gave up as something tells me that the A50 might have very proprietary storage drivers, because no matter what I do, twrp refuses to see any device attached. Also, though most allwinner socs are well docd, the a50 isn't as much and afaik the allwinner barely acknowledges the a50. Though I am really happy I got to develop some more experience with things like fstab and it was a lot of fun

Outstanding job. That's no small feat when dealing with Allwinner, and especially their more obscure A-series chipset like the a50. So, TWRP will not recognize USB OTG device or other attached devices?

It won't even recognize the internal storage. When maneuver my why with the barely functional touchscreen to the log option, it just shows a long list of "couldn't mount"s. And no matter what I do TWRP has zero access to internal or external storage. Be it otg or microsd. I've tried several way of formatting the fstabs layout. Be it the average template I would find within twrp, or base my fstabs on those in stock recovery. Anyhow, it was taking alot of time in my life and started to get annoying /hj. Though I am glad I developed some experience. But I wanted to make something that would require alot more time, but would be alot more fun to make. It's a series called "Bull[censored] simulator." Though it's not really a simulator. And the real game lies within. Well... The game itself. As in the hexadecimal, the itchio page's assets and so on. Atm I am busy with a part that inserts it's lore into a Pokémon rom hack I will probably call Bull**** Sim: Pokémon Edition(Working title of course lol) so sorry for abandoning this job. Though I AM glad that people still take interest. Maybe I'll get back to it someday if I ain't beaten to the chase
