I have not looked into Lineage OS at all yet, and frankly that is probably well above my capabilities. I can barely spell "dev", much less work like one. But I am bloody minded enough to trial & error my way through building the original kernel in order to add new drivers, and to hopefully increase the performance speed if I can see an easy option along the way.

I'm not 100% sure that I have built a kernel that will work properly on the TB3-850F, much less sure about upgrading the device's whole Android OS to something newer.

After examining the device with "Device Info HW" from the google play store, I know that with the current updates installed on my TB3-850F, Lenovo is using the Linux 3.18.19 kernel, and "gcc version 4.9.x-google 20140827 (prerelease)". So that's why I focused on the Kroah-Hartman 3.18 kernel source code after getting so many frustrating fatal build errors with the other two that Fran89 directed me to use. That's the only other source code that I could find purporting to be for Mediatek devices, and using the Linux 3.18 kernel. It's also why I used a relatively older Android toolchain for the build.

The Kroah-Hartman source code is actually for the Linux 3.18.104 kernel, so I am not sure whether that will screw everything up when the image gets flashed to the device. I think it will be ok, but I'm certainly not 100% sure. Hopefully there are no really major differences between 3.18.19 and 3.18.104. It seemed to take on the specific TB3-850F configurations, anyway.

I have zipped up and attached the two .config files (the first one created by a menuconfig exercise under the error-ridden Lenovo source code using the 3.18.19 kernel, and the second one created from the Kroah-Hartman source code using the 3.18.104 kernel). So you can open them in a text editor and compare.

I also attach the last 1000 lines of build messages generated by the GCC compiler before it built the image. Unfortunately I did not direct all the message output to a text file during the build, because of all the weird "config Y/N" questions that begin the Kroah-Hartman build script. The compiler must output its messages to the screen, so you can answer the config questions, or else there is a fatal error right at the start. That means all the build messages scroll off the top of the terminal screen, except for the last 1000 lines in the buffer, unfortunately.

If [MENTION=7383447]MotoJunkie01[/MENTION] wants to PM his mailing address to me, then I am happy to send him a USB key with the entire built source code, objects and images, if would be useful. As I said, I'm not a git user, so finding a public host for a 2.3 GB file, or even a compressed 700 MB file, does not have an obvious solution to me.
[Android General] limited_imagination:
Damn, I can already see some differences between the two .config files, that may be show stoppers.

Despite the Kroah-Hartman source code supposedly being made for Mediatek devices, there are no 6735m specific configurations in that .config file, as there are in the Lenovo .config file.

Damn, I may now have a buildable source code, that doesn't work with the specific device.

I will await some more experienced person's comment.

Maybe I will try again to merge the two source codes and use the Lenovo .config with the resulting bodge.

Argh.

Argh Argh Argh Argh

May I suggest that with your sheer B-minded determination at least, you may be the one to properly port our device to LineageOS 14.1 for TB3-850M I posted link to, and possibly debug.

This shouldn't be difficult as it will probably boot as is. Critical hardware / partitioning is essentially the same. (Others report running TB3-850F firmware on TB3-850M and seem only to lack SIM support). Probably only need to fool TWRP to install first. PW.

PS [MENTION=7383447]MotoJunkie01[/MENTION] may have started / attempted this already.

I'm not getting this OTA push for TB3-850F yet. (You still say TB3-8503F ???)

Still have TB3 850F S100031 171010 ROW as the latest.

Please could you post the complete xxx ROW designation for your OTA update?

Thanks, PW.
[Android General] MotoJunkie01:
As far as I know, having checked for system updates earlier today, the latest stock Android 6.0 build for the TB3-850F is TB3-850F_S100031_171010_ROW, with a security patch level of September 5, 2017. However, if anyone is receiving notifications for a new OTA, please let me know so I can update the stock ROM threads accordingly.

As of late, with a sporadic and robust work schedule, on top of impending health issues, I regret I have been completely unable to dedicate any time to my threads here on XDA. I wanted to apologize & at least give reason to my chronic absence from here. I'm going to take a couple week hiatus from XDA until traveling for work slows down and I can get myself back up to health. I would humbly ask [MENTION=7550078]pndwal[/MENTION] to keep watch of my TB3-850F threads and, if possible, address any questions and issues in my proxy. Because you have a broad knowledge of Android in general, as well as a keen understanding of this device, your help would be awesome, and truly appreciated. [MENTION=7550078]pndwal[/MENTION] if you are unable or do not wish to have this task, I totally understand, and would ask any capable member, or members, to assist until I can return regularly. I am truly uplifted to see this and my other Tab 3 threads growing with new members, new ideas, and fresh development. Thank you all for patience and understanding...
[Android General] Diomorgan:
will send you screenshoot and complete xxxcode of the OTA as soon as I'm back home (24/48 hours) It's the g&arbest wifi one, i thought there is only one (now thei are starting selling the 4G for $189 that's absurd since I bought mine wifi for $100 or less maybe during black friday since I was damn bored of the new fire (that in Italy is pretty expansive-, almost same price of Lenovo due to the fact that Prime is $20 a year).

I would like to know (and in what kind of format) it download it so maybe I can copy it and zip it and you can apply in some way.I can download, but on reboot to apply I got TWRP, so no update...:(
[Android General] pndwal:
Thanks, will be waiting . . . PW

---------- Post added at 11:39 AM ---------- Previous post was at 11:08 AM ----------

Yes, re OTA update, we'll wait n see . . .

Yes, I check new posts regularly, so no problem with your request. I'll assist as I can. (Can't just ride that Gravy Train can we? - Thanks for vote of confidence) PW.

Gearbest WiFi tablet? Wouldn't be Lenovo P8 (TAB3 8 Plus) TB-8703F?

(They recently pushed TB-8703F_USR_S000034_180109_ROW for this one. Model looks similar to what you typed, as does OTA version, but totally different beast with snapdragon 625 CPU.) PW
[Android General] Diomorgan:
You are totally right and I'm totally dumb, I'm very sorry the update that is asking me is TB-8703F_USR_S000034_180109_ROW, I just known that there are 2 wifi model , one MTK and one Qualcom...don't hate me, but wich one should be faster? At least I bet your MEDIATEK doen't reboot itself...
[Android General] pndwal:
Quite alright. We all suffer a little dyslexia. Pobody's nerfect.

Think your Tab 3 plus should be much faster device, with Snapdragon 625 chip, 2.0 GHz Octa-core CPU (our mtk chip should be 1.3 GHZ, but is crippled to 1.0), and 3GB RAM (ours is 1GB).

However, many people have reported bugs / dissatisfaction with your model. Don't give up though, I think the recent OTA update addresses most issues, and most likely your reboot issue too.

I'd be restoring stock recovery (& boot image if you rooted or otherwise modified stock ROM) on your tablet so you can apply OTA update without problems, then check for improvement.

Proper XDA threads for your device - I found these. May be others:

[Android General] limited_imagination:
Still battling with the source code.

Time consuming and tedious, but I make small gains, a little at a time, and I cheer after each semi-successful compile.

The M4U drivers and video drivers were my most recent mess, that I seem now to have beaten in this hacked up source code. I have cleared those errors and I now move on to more, a little at a time.

It will take more time, so no promises as to deadline. Buy a new device if you are in a hurry. :) Or maybe someone else has moved forward faster than me, hopefully.

God knows if this will result in anything useful. Maybe I am just wasting my time.

My current build log with errors is attached as a text attachment. Any comments on the various warnings and errors appreciated.

I set the Werror to "ignore" on the compiler, to get the full picture of all the horrors requiring amelioration.

Unsurprisingly, it won't build the image yet, but it's getting closer.

We shall see, I guess.
[Android General] pndwal:
Well done getting this far! Hope you keep riding that steep learning curve.

From-ground-up-built kernel would doubtless be an invaluable asset for our device. Hope you can find source code for 6735m configuration. Please keep us up to speed will progress.

If it's of interest, 4PDA user al_rus posted "Firmware Port Resurection Remix v.5.8.5" (final Android 7.1.2 Nougat build) for TB3-850M on the Russian forum TB3-850M thread. Thanks n regards, PW.

[MENTION=7383447]MotoJunkie01[/MENTION]

Couple of quick questions regarding your LOS 14.1 rom in the works:

- will it have any non-working hardware. Like a camera or some sensor that (right now?) you can't figure out how to make it work?

- will it have multi-user and kids mode support? I don't now if LOS has these features but they come bundled with the official stock rom and, unless someone teaches me a workaround for not needing them, they are a 100% must-have in my case with a 7yo daughter.

Thanks in advance.

so i been dealing with this root methoed for awhile and i finaily got twrp on my phone and all including SU

but i install ccleaner and it shows my phone s not rooted so what can i do to fix this

i have SU 2.82 i did the advanced wipe on cache and dlvik i did a format data still no root is showen
[LG V20 Questions & Answers] me2151:
you have to install the su zip AFTER doing everything else. If you did format data you deleted your root if it was on there

[LG V20 Questions & Answers] LASERWOLF452:
ok this makes no since, i gave up useing ccleaner (cause it has a root checker) and i installed titanium backup and it was able to trigger the SU

so why not ccleaner to get SU going cause i use it to uninstall the BS apps verizon puts on the phones
[LG V20 Questions & Answers] Artimis:
ccleaner like many old apps have not been updated to work properly with system-less root. They are still looking for the su binary under system/bin or system/xbin. You'll need to contact the app developer about that. Alternatively, you can go into SuperSU and have it install the binary for old-school root but I don't recommend it.

You can use a ton of other apps to get rid of the Verizon bloat (titanium backup being one of them).
[LG V20 Questions & Answers] LASERWOLF452:
to be honest with you, i feel dumb lol this is the first systemless root i ever messed with i am used to the old ways but i am happy i found out this phone is rooted i was going everywhere like crazy like why the hell is there no root but i figured it out its a good method that you made along woth others i did it so many times i just memorised this method hehe commands and all

hey guys hope u are doing fine , so lately there being this way to hide the system folder of a rom zip so u can't access the system/app or syste/priv-app so i really need to edit a rom like RN or lineageOS before flashing it , is there a way u can show me please ?
[LG G2 Mini] Vagelis1608:
The /system folder is inside system.imgin the zip

Use 7zip to extract just that, mount the IMG with some kind of special program (windows doesn't recognise ext4 partitions) edit it, then put the IMG back in the same zip.

BTW, I came across a good tutorial on what you are trying to do some time ago. I don't remember if it was here, on XDA. Have you tried googling it?

yeah thnx i tried googlin but all i found was obsolete like posted in 2012 back then the editin was simple and the system file wasn't hidden , and what kind of special programs i can use to mount the image ? m already usin 7zip

[LG G2 Mini] Vagelis1608:
Flash the ROM, mount /system and use recovery's built-in file manager to delete whatever you want.
[LG G2 Mini] berraffarouk15:
yeah i know i got tired of that methode so i wanted something more efficent :P
[LG G2 Mini] Vagelis1608:
Well, the way I see it, it's more work to modify the IMG than to use the recovery's file manager.

Also, an idea I had while typing the above, you can write a small script to automate the process. You can the run that script from the recovery's built-in shell.

I can help you with this.

I have all of my software, movies, pictures, ie cache, and pictures installed to my storage card. My problem is that my main system storage seems to be decreasing by the day.

Has anyone else experienced this problem? Any help would be greatly appreciated.

I'd also suggest using PocketMechanic or MemMaid ... and I'm sure SkTools will do it too to clear out all the crap that you can.

With PocketMechanic, you can "relocate" installations from the main device to the storage card, and that may help you as well.

Any of the Tmobile crap ... myfaves, hotspot logins ...etc... but you can install most of those with a cab.

3. Will flashing the phone with one of these roms void the warantee on my phone?

Yes. Theoretically. But again, if you ever need to send it in, you can install the Stock Tmobile RUU and hopefully you won't have any problems.
