[Thinkpad Tablet Android Development] MotoJunkie01:
You are very correct in your analysis of extension numbers and variant specs. (By the way on disassembly, I should have mentioned that it is necessary to remove the battery and some of the reinforcement adhesive in order to view the MediaTek nomenclature identifying the SoC.) You are likewise correct on your scatter file analysis. In terms of kernels, since our TB3-850F stock OS is based on Android 6.0_r2, our supporting kernel is version 3.18.19. With the Nougat (7.1.2) LOS and RR custom ROMs to be ported from 850M, we need at least a version 3.18.31 kernel version to boot the ROMs and for hardware blob support. In fact, both ROMs would boot right now and would, in theory, function completely normally if we had a supported kernel. Of course you already know all this so I'm merely thinking out loud so to speak. My colleague (who assisted on the old BlueSpark kernel project for older Motorola smartphones) is helping me compile a Nougat supporting kernel from source. And, since Lenovo did release the source code for the camera drivers for the 850F, custom shims won't be needed and the available blobs can be put in place for fully normal camera function. (Although the cameras appear to be identical on both the 850F and 850M, the difference in SoC platforms gives rise to different hardware blobs.)

Interestingly, and just like the stock OS for our device, the LOS and RR Nougat ROMs are compiled to function on the 850F and 850M. So technically, no porting is needed whatsoever on the ROMs themselves. The only real work is compiling a kernel to boot the ROMs. This is where I hope to gain some much needed knowledge and instruction on the Linux kernel and GCC. To keep you up to date, I can proudly say that a version 3.18.31 kernel is currently being built for the 850F. Soon as it is finished I will plug the custom /system files and new kernel into my Android kitchen and, much like Chef Boyardee, cook up something real proper-like. :silly:
[Thinkpad Tablet Android Development] pndwal:
Well, you certainly know how to wet one's appetite! - Thanks for the heads-up - Hope you get into the kitchen soon. I'll try to generate scatter file for ZA170082AU soon and post. Thanks, PW

Sounds like you have a lot if good help. Thought I'd just mention a contributor who whose expert help broke ground for TB3-850F (in [MENTION=5273366]Lister Of Smeg[/MENTION]'s thread), [MENTION=5919159]Tzul[/MENTION], who may be of assistance.

Interestingly, among other things he wrote:

"I have mentioned this in the other topic you found. It's normal that scatter files sometimes don't list the exact chip type in the platform field. My Tab 2 A10-70F for example has an MT8165, but the scatter file says "platform: MT6752". The name that is used there must exist in the config files of the SPFT (see platform.xml and storage_setting.xml, for example), and the settings that are defined there must be "compatible" with your actual chip type...

I don't think that waiting for SPFT updates will help. Like I wrote above, the Tab 2 A8-50F was based on the same MT8161 chip, and its scatter file lists "platform: MT6735". There's either something strange going on with your Tab3, or it's a driver issue."

All best, PW
[Thinkpad Tablet Android Development] MotoJunkie01:
That's good info to know. And yeah I may just give that member a shout and see if he'd be willing to join forces on developing for the 850F. A small development team would be nice -- and you would be more than welcome to be a part. You definitely have a broad understanding of Android and you know the 850F inside and out.

I'm still leaning towards the possibility that Lenovo sold variants of the 850F.
[Thinkpad Tablet Android Development] pndwal:
Thanks for vote of confidence. Happy to help where I can, and I'd love to set up a machine for foray into 'developing', but I have serious time constraints presently, so just an 'ideas man' (and willing tester) for now.

Looking forward to being kept up to speed with progress though. Regards, PW.

Yes, I think that's a given also. Didn't intend to infer otherwise - just thought Tzul's info might be of interest / use because of variations (and because scatter file info may be misleading but also may work fine for 'compatible' platforms (chipsets) - I'm guessing this may make things simpler when it comes to 850F/M differing chipsets as well as any different chipsets within 850F range)... PW.
[Thinkpad Tablet Android Development] MotoJunkie01:
Yes I totally agree with you there.
[Thinkpad Tablet Android Development] MotoJunkie01:
Ok [MENTION=7550078]pndwal[/MENTION], I have successful boot of the LineageOS 14.1 ROM for our 850F. Everything force closes and crashes on initial setup but I know the issue there. (Involves the .dex files in /system/priv-app and /system/framework. I'm debugging now to get things stable enough to launch. Fingers crossed.
[Thinkpad Tablet Android Development] pndwal:
Great news! Looking forward with eager expectation. Really appreciate your efforts :) PW
[Thinkpad Tablet Android Development] MotoJunkie01:
Most apps are now stable on the LOS build. Ironing out Bluetooth and WiFi issues and hope to have a beta build posted this week.
[Thinkpad Tablet Android Development] pndwal:
Good work :svetius:

I think you're going to be famous (- at least in Russia! ;) )

Looking forward to testing. Thanks n regards, PW.
[Thinkpad Tablet Android Development] MotoJunkie01:
Haha. At least famous somewhere, right?
[Thinkpad Tablet Android Development] pndwal:
Sure it'll soon gain traction elsewhere too. Keep up good work! PW.
[Thinkpad Tablet Android Development] MotoJunkie01:
Thanks [MENTION=7550078]pndwal[/MENTION]. And one thing is sure as well: once this first custom ROM is fully ported and stabilized, the blueprint for future ports will already be hashed out. Development will be much simpler on future custom ROMs. I've used the FisH hijack exploit as well, which worked wonderfully on this device. Although FisH is typically reserved for locked down devices -- not the case with the 850F -- it still came in handy on the boot image. I'll explain more on my custom ROM thread when posted. It'll interest you [MENTION=7550078]pndwal[/MENTION].

[Thinkpad Tablet Android Development] voland34:
Hi. I've been waiting for a new rom for this device for a while, but just yesterday found this rom version that seems to improve speed on 850f. This is much needed now as my daughter is using this tablet at school, and original rom is quite laggy. So i tried to download from link at 1st post, google drive, but it needs some permission. I just realized [MENTION=7383447]MotoJunkie01[/MENTION] account is disabled so i might never get that rom link from that account. My question is: does anyone keep copy of this rom and could upload it and provide me with a working link? It would be very much appreciated as i cant find any other option to improve this tablet enough to make it usable at school. Thanks!
[Thinkpad Tablet Android Development] pndwal:
Yes, unfortunately many have found this Mediatek 1.0 GHZ tablet a bit too slow, but we only have stock, and slightly modified stock by [MENTION=7383447]MotoJunkie01[/MENTION] for this, and I've only used pure stock with root (Magisk). I don't think there is actually any speed improvement to be had with MotoJunkie01's stock package.

As you may know, he has been working on, and completed adaption of a Russian port to TB3-850M for TB3-850F. However, a week ago he had a bit of an altercation with a member and, among other things, said he was no longer intending to post this on XDA, and hours later his account was disabled and the thread cleaned by MODs.

As I wrote here: https://xdaforums.com/android/general/guide-lenovo-tab3-8-tb3-850f-t3559786/page34 :

This port would have been a boon for all of us, and no doubt would have run faster and smoother, as has been the case for other devices when migrating from M to LOS 14.1 (N), however seems it will have to wait until [MENTION=7383447]MotoJunkie01[/MENTION] surfaces again, or a Russian Dev. or someone else attempts port to TB3-850F.

Sorry to be the bearer of bad news regarding this, but we are all disappointed and in the same boat. Regards, PW.
[Thinkpad Tablet Android Development] voland34:
Thanks 4 update

I see, certainly bad news for us. Thanks for the info, and lets hope a lineage version is ported soon as you mention.:good:

ROM backup anyone?

I konw developer isnt around anymore, but if anyone could PM me with a copy of this zipaligned, rooted ROM based on stock 6.0, it would be most appreciated (posted download link isnt working anymore as developer is done with all this). Just Stock as it is, is a real pain (very laggy). Thanks...
[Thinkpad Tablet Android Development] pndwal:
I never downloaded / ran this as some users experienced unexpected problems with it. (Don't know of any mirror links either.) Not sure it would be less laggy than pure stock in any case.

Someone else may be able to help with a copy / link. Regards, PW.
[Thinkpad Tablet Android Development] voland34:
Ok, thanks for your opinion. Then its a pity not to be able to have any rom developments; tablet is a bad acquisition as it is. Regards
[Thinkpad Tablet Android Development] pndwal:
Yes - bright screen and good sound, but very mediocre CPU. Apparently lenovo is to go with Qualcomm more in future as Mediatek has been pretty disappointing. I think low end (400 series?) SnapDragon would bring much better stability, smoothness and speed than Mediatek offering, but that won't help us poor TB3-850F users... PW
[Thinkpad Tablet Android Development] DeblaGaming:
Why do I need permitting to download this ROM?
[Thinkpad Tablet Android Development] pndwal:

I think message re permission needed is just a default response. I think all OPs links to hosted files are now disabled or broken. This goes for some 35 of his threads incl. threads for Tb3-850F, Moto E, Moto G, LG devices and others.

I have taken the original and heavily buggy version of lineageos and fixed a lot of the major bugs that came with it. As I mentioned, I was doing this for myself but figured I may as well share it. As I previously said:

QUOTE: "I have been using XDA for years but have mainly been using the roms that other dev's have built and also looking for answers to any questions I had to potential problems throughout the years. I have never felt the need to create an account as I felt I had nothing to offer, everything that I could do was already being done by someone else and I don't post questions because 99% of the time a quick google of the error code or problem will turn up an answer either on here or somewhere else.

I won't be accessing this account again so any bugs that remain will be left in. I did plan on porting this over from scratch but I found it was easier and better to work from the previously buggy 14.1.

[Lenovo Yoga Book Questions & Answers] tjupille:
My YB refuses to boot. Symptoms:

- when plugged into charger, white indicator light pulses slowly (about 3 sec on / 1 sec off); doesn't matter if lid is open or closed

- If I hold the power button down for 11-12 seconds, I get a short "haptic feedback" buzz, but no other response.

- If I then press the power button briefly, I immediately get a short buzz but no other response.

- No combination of button presses does anything different.

All of the above is with the charging cable connected. If I unplug the cable, the white indicator light continues pulsing until I press the power key for 12 seconds, then it goes out (no haptic buzz, though).

All of this happens with or without an SD card installed.

Windows doesn't see it as storage, and adb doesn't see it at all.

Any suggestions (aside from "it's dead")?
