[Q] How can I upgrade my generic tablet (brand Lenco)? - Android Q&A, Help & Troubleshooting

Dear Xda-team
First of all, let me congratulate you for the excellent job you do.
It’s a wonder to the eyes to see the degree of professionalism behind the visible side of this site.
I hope you can help me with my issue, having in mind my experience that I don’t have any experience yet installing new android firmwares.
I have a Lenco Tab-720 with the following carateristics:
• Android 4.1
• 8gb internal memory
• 512 MB Ram and 1.2GHZ cpu
and when I connect it to my computer, it says Alcatel Android ADB Interface, somewhere inside the driver details.
The tablet itself is nice in size and the screen is good, but it’s awfully slow, even if I have only facebook, a game or two, some Banking apps and outlook app.
My issue is that I can't find no tutorials or how to that explain to me how can I simply change my sluggish android 4.1 to something more fast.
One good thing about this tablet, is that comes with the following option
“Save and Reboot” ----System Upgrade ----Recovery mode – Reboot into the system in Recovery Mode.Can clear the data or system upgrade.
From what I understood when reading other threads, is that that will allow me to skip a custom recovery mod, correct?
Therefore, could you please explain me which are the necessary steps in order to make this tablet run smoother, while improving the overall software experience?
I honestly don't know if the tablet will handle Android 5.0 , but maybe with kitkat it will be tasty enough.
Thank you so much for your time.:good:
Best regards

Dear members
I contacted Lenco support team and they send me a firmware file:
A13_86VS_M758CHD_1303086.20130329
But , when I open PhoenixSuit 1.08, it says:
Firmware version = v1.2_13011 A13_86VSH_M758CHD.20130329
Android version = 4.1.1
The A13 that I see above has anything to do with other A13 tablets?
If yes, how can I root and upgrade my tablet?
Thanks

[Q] Unable to install adb drivers on Toshiba Folio 100, Code 10 error?

Hi all,
I'm having real issues trying to root my Toshiba Folio 100 which I got today. Basically, I'm at the part where I install the adb drivers. While I'm usually pretty good with Android, I thought maybe it's where I've done something wrong. So, I literally uninstalled everything and started from scratch with the Android SDK. I followed this guide to the letter here:
addictivetips.com / mobile / what-is-adb-and-how-to-install-it-android/
Then carried on with this guide here:
addictivetips.com / mobile / enable-adb-usb-drivers-for-nvidia-tegra-based-android-tablets/
I carried on and on (although I changed 0955 to 8086 in the inf file as that is my device ID) and when I go to select the drivers, I push along even though it gives me the warnings and when I get to the end, it comes up with this error:
"This device cannot start (Code 10)".
Googling this error comes up with a bunch of related queries that don't relate to me, and the MS website is absolutely useless for resolving this (it tells me to update the drivers).
So, I'm at a loss. I've tried everything I can think of and to no avail. So, I'm praying you guys can help me out so I can root this tablet. If I can't, I may as well sell it back on or return it, as this device doesn't mean that much to me without the Marketplace or Custom ROM capabilities.
Thanks in advance!
EDIT: My apologies, I should list my specs just in case it's relevant (I know the OS version will be, at least)
Core i7 2600K
GeForce GTX 560 Ti
8GB DDR3 RAM
Windows 8 Developer Preview
Flashing recovery for the ones who updated to the latest build 18 febuary
I have the Folio 100 from august 2011. I have installed the CM7.1 ROM following step by step this guide:

I don't know if it will be usefull for you.

[Q] How to install newer os on this tablet

Hi everyone
I have the following tablet made by Mach Speed Technologies:
Trio Stealth G2 7" display
1GB RAM
CPU: Dual Cortex-A9 Dual 1.5GHz Multi-Core (its a dual core with a total of 1.5GHz)
its not rooted yet, I don't know how. If it needs to be rooted for this can someone quick explain that?
It came with Android 4.0 and has never updated through the settings, and the factories website does not even mention this tablet. The guy at Radioshack said I could install the update myself so here I am trying to figure out how.
If possible my original plan was to just instal the newest Android release. But today I just found out about ROM's.
So how do I install the newest Android release or if that's not possible a very secure custom ROM?
On one website it just said to put the rom image on a sd card (or in my case a microsd card) and put it in the tablet, then the tablet would use it as an update after asking you with a pop up. Is that true?
I have a bit of experience with Linux and coding but none with Android
with that update through sd card is true but most of times you need to have specific app or recovery as it may be treated as a rom and in that case you need to be rooted and have recovery. if you have experience u good with android as it is based on unix core
Well, I guess the first step is to be rooted then? How do I go about doing that?
I have the "Root with Restore by Bin4ry" downloaded on my computer and the usb driver installed from the google sdk manager.
But my computer does not see my tablet at all.
I have the same tab I have got adb to somewhat pick it up an it has aml flashtool and safe mode this shows u how to get into all those all but for safe mode copy this an past after youtube.com

[Q] Need help with Cube U25GT RK3168

I have been away from Android for a good many years now, over in iOS land.
Recently I picked up a Cube U25GT Dual Core with the Rockchip RK3168 A9 processor.
Out of the box the developer menu is available, but I would like to do a full root on the device so I can use this as a development platform where I can run strace or something if necessary.
The problem is there is so much information out there and much of it is device specific that being pretty much new all over again I have no idea where to start. I read through some topics here but none that I read were to the point and I quickly found myself in a tangle of threads.
The stock firmware is available but I was unable to mount the image to extract anything. I am guessing it's not a standard disk img file.
Could you try this and let me know if it works? Im gettin my tablet in a day or two

Some Hacking in Yoga Book

Hi folks.
I'm an Android firmware developer (you can see my posts here in xda) that got a yoga book yesterday. For me it works at it should (by now) but my hacker soul speak to me and said: "at least take a look to see what you can get from this device". I don't have many time, so I can't spend time doing roms or fixing things by myself, but I can share with you some info I get and help you with my knowledge if someone is interested in "play" with this device.
First of all, I'm not responsable of anything that you can break following these steps. Almost all of them are tested and with some common sense you will not break anything, and if you break anything I will try to help you to fix it (if you are polite), but this is a work in progress and hacking and the possibility of brick the device is always there.
I only have the Android version without LTE, so I only tested in my Book.
So, here we go:
1) Secret codes:
I get this codes decompiling EngineeringCode.apk with apktool. Be carefull with them:
####0000# - Display version info
####7599# - Display hardware info
####8375# - Display baseband info
####1111# - Factory test
####2222# - Display SN
####7777# - Factory Reset???
####5993# - Display internal frameWork version
####7642# - Cut the power off to reload the PMIC - This command shutdowns the device. Just press the power button to reboot.
####5236# - Display LCD name
####2834# - ES close test
####8899# - open the ums mode default for debug
####3333# - offline log
####3334# - offline modem log
####9527# - Mediaplayer setting
####78646# - RunIn test
####6020# - switch country code
####59930# - Display current country code
####8746# - Enter engineering mode
####4227# - Enter engineer test
####357# - DLP_TEST
To use these codes, open the contacts app, press the search button and enter the code in the search bar.
2) OTA Images
You can get OTA images directly from lenovo servers. Just open your browser and paste this url:
http://fus.lenovomm.com/firmware/3....WW06_BP_ROW&action=querynewfirmware&locale=en
Change device model if needed (LenovoYB1-X90F or LenovoYB1-X90L)
Change curfirmwarever to a valid OLD firmware, this way you will get the next one in age.
Change locale if needed.
With this url you will get a download url at the end of the result page. In this case: http://tabdl.ota.lenovomm.com/dls/v...S000426_1705080316_WW06_BP_ROW_WC80C2A0F2.zip
These images are not full ota images, they are diff versions. This means that we can't use them to mod the image, or recover a bricked device, but this is a first step
3) Custom images
We don't have real sources to build a custom image (the lenovo's open source files are useless), but this doesn't mean that we couldn't modify stock images to take out useless apks or get better performance.
We can get this using an Android Kitchen and a full update image for the device.
As Android kitchen you can use SuperR kitchen (https://forum.xda-developers.com/ap...chen-superr-s-kitchen-v1-1-50-v2-1-6-t3597434)
As full image, I only tested the one here (https://easy-firmware.com/index.php?a=browse&b=category&id=19521) because I can't download any newer one.
I tested uncompressing it, deodexing the apks and doing a new image. But I don't test it in the device because I need to install twrp to flash the new image and I don't have time to test. But this should work, I did it many times so if someone is interested I can give steps to do it and support for testing.
If someone can get the latest full images, send then to me and maybe I can get some time to do some tests.
PD: Probably we could use this as a base to get LineageOS 14.1 working: https://github.com/latte-dev/android_device_xiaomi_latte/tree/cm-14.1
So, if you are interested in some hacking with the Yoga Book, contact me and we could team to get the most of this device.
First of all thank you for your post, it´s really useful
if you could somehow manage to boot windows on this machine it´s by far the greatest war we have right now.
Il promise you a lunch or dinner on Lisbon whenevere you want!

Sorry, my knowledge of Windows is only user level . Install it in personal computer to play games .
But I really don't know why people wants to run Windows there, it will go slowly than Android and its less touch oriented... but I suppose that this is a chat for another thread

Have you tried running it through Crossover? It may be in its infancy but i have got a few apps running OK with it.
I have the full "YB1-X90F_USR_S000196_1611040312_WW06_BP_ROW" I can upload somewhere if anyone can suggest a good site to do so without signing up? The file is about 2.5gb
It will be great if we could get the latest version, because maybe these older versions have older files that we have updated in our tablets.
Mixing files could give unknown problems
The current TWRP is based on the new Yoga Tab 3
I am starting to think they do not do full roms for this in the same way they do for a lot of their other devices.
We know the otas are available from tabdl.ota.lenovomm.com/dls/v6/ and are named according to the 2 builds that it bridges. As easy-firmware had the december full rom under the file name B1-X90F_USR_S000196_1611040312_WW06_BP_ROW-flashfiles.zip I had hoped that I could work out the file path to pull it down.
There were some interesting ideas here, https://forum.xda-developers.com/android/help/how-download-stock-roms-lenovos-ota-t3109507 but it seems there is a difference between phonedl.ota and tabdl.ota
Queries to full roms that work for phones, don't seem to work for the yoga book.
Anyone with more web knowledge able to pick this up? I am not sure the files are there but I feel they should be.
Good luck
Update: the downloads seem to be hosted via CloudFront. An Amazon service, but I can not find out a way of listing the available files. The latest full rom would be
http://tabdl.ota.lenovomm.com/dls/v6/YB1-X90F_USR_S000426_1705080316_WW06_BP_ROW_WC80C2A0F2.zip
But the Last 8 chars are random and we do not know what they are.
So we have two hopes. First work out the right query to the link from fus.lenovomm.com or two find a way of listing files available in tabdl.ota.lenovomm.com/dls/v6
Not sure I have got much further but ill keep trying when I can.
Hey, I should mention that I have some files that you may find helpful; I got them from the easy firmware website. They're all the .img files for each partition in Android (ie. boot.img, cache.img, config.img, factory.img, recovery.img, system.img) as well as: biosupdate.fv, bootloader, firmware.bin and gpt.bin. However, these of course aren't in the normal "flashable .zip ROM" format. So unless you know how to take apart these .img files they aren't very useful. If you need any more help or have any other questions about how far we've come on our own, feel free to ask. danjac also has great knowledge of our efforts.
Yes, I know how to use them, unpack, modify, etc. But what I want is the latest version, no a old version (I hav these files too). If you have them I can do some changes, debloat, etc.
Anyway, I see little interest in custom roms in this forum ( probably because it's not a device with a lot of users or the users are not the techy kind), so I prefer to help others with info than do a custom rom that only 2 or 3 people will use. Doing custom roms is a time hungry task and probably it doesnt worth the effort. Anyway this device is not full of bloatware like samsung ones, so it useable as it is.
As I said in my first post if anyone is interested I can give some hints and support to modify the full image (but only the latest one).
It's so sad that there are only a few interested owners of this tab - it's such a nice device but i fear the day lenovo decides to end their support for it. There will be no custom roms to switch to and keep the device alive - it will be a soon to be bit of old tech garbage BTW. I still use my Asus Transformer Prime because of the nice community
@NiffStipples I fully agree. This device is so powerful and its a suprise that it is invisible to the "market". In my humple opinion the normal ROMs aren't that bad besides missing updates but I would love to see all the power served through a custom rom. unfortunately programming is not my business

Interesting - is Crossover good (and does it require factory reset)?
Hi, It works well with some things and not others. Often the why and where are not obvious. It is basically "wine" the layer that allows some windows apps to run on a linux install. Tweeked to work with android. Just an install to put crossover on. Then another install (Within crossover), to put you app on crossover. If it doesn't work out of the box, there windows libraries you can switch out and dependencies you can install. (Eg: directx , .net) Even if your not technical. I would say get on the beta program and give it a try.
Hi! what do you mean by "lenovo's open source files are useless"? do you refer to this packet on lenovo's suppport site? download.lenovo.com/consumer/open_source_code/lenovo_yb1_x90f_l_osc_201608.zip
I've entered the Android YogaBook's BIOS and noticed that VT-X is enabled by default! With Limbo x86 we could get a fully working virtualized Windows or Linux, if it wasn't for... KVM. It seems like it's not enabled in Lenovo's default kernel. Could we get to recompile the kernel with this option on? i'm not a big android/ROM expert but i surfed the open_source_code folder from Lenovo and it seemed, to me, that we could rebuild the Kernel at least.
This could really change things!

Newbie wanting to re-image a Touchpad

Hi All,
Firstly, I am pretty much a 'newbie' here....so apologies if my questions are inane!
I have an original HP Touchpad - with HP webOS 3.0.5 (4GB RAM/ 16GB Storage) that has been sitting around since not long after getting it when I used to work for HP. I have been contemplating re-imaging it as an Android OS for a number of years, but scared off by my perceived complexity of the task.
But the time has come where I need to either try it - or toss it out. So, my question is........is there a process, that is reasonably easy to follow, for a non-Android guy to achieve this re-imaging of the device to whatever latest version of Android it will support?
Again, apologies if my question is too simplistic. If it's not reasonably intuitive for a layman to follow, let me know and I'll recycle the device. I AM however, always UP for a challenge, so happy to try whatever is required.
Thanks for taking the time to read my plea! And I would sincerely appreciate any responses to my quest.

HP Touchpad from WebOS to Android

The task is simple, easy and fast.
Basic process:
Novacom driver needs to be install on PC that allows communicating to the Tablet and load the required file:
Automatic_Wipe_All_and_Create_Android_with_Swap
Tablet needs to be place into WebOS recovery mode.
Once the Automatic_Wipe file is loaded into the Tablet it does everything.
When done the Tablet reboots into Recovery and any Android ROM can be flash ( install ).
That is all to it, the following are options and details but the process is the same for all.
How to activate WebOS recovery mode: Battery must be charge and be able to boot into WebOS.
1. Tablet must be off and disconnected from the USB cable.
2. Hold the Tablet with the Power Button facing at the Left Top from the user.
3. Press and hold at the same time, Power, Volume Key (Right) and the Home Button ( Right side by the USB connection).
4. A white USB Symbol will show, then connect the Tablet to PC

1) How long does it take to root?
2) is it still a worthy tablet and responsive? Or am i better off getting a new samsung tablet for $100? (by definition of worthy and responsive - i am still ok using an old 2007 dual core laptop with an ssd since it can handle most mundane tasks/browsing etc. but without the SSD, its paperweight to me)

Rooting is just flashing a zip file within TWRP (the recovery which is the "central place" to flash everything outside the OS). For getting root you need to flash a zip like "SR5-SuperSU-v2.82-SR5-20171001224502.zip". That's normally all.
Don't expect too much out of it. The limiting factor is more the 1GB RAM, less the dual CPU core. But I would push you to give it a try. And of course, all depends on your usage of the TP. But following the different guides of HP_TOUCHPAD for getting the MAX out of the TP, one should be able to use it for several "daily things" like watching YouTube, checking eMails, as a SmartHome Monitor, Weather station and other things, which do not need the massive power and memory of actual devices.
