Did you get email yet? Mentions alert me!(???)

I was referring to performance mods that tweak kernel in general, incl KA.

I cited this example as [MENTION=6864096]NATO66613[/MENTION] has stated he was building on [MENTION=4479868]desalesouche[/MENTION]'s ('no frills') huawei_msm8916 kernel to produce Soviet Bastard, Soviet Star, Octo Soviet, and other kernels for Y550. He was, as I said, able to enable many Kernel Aduitor enhancements that otherwise caused overheating / instability / screen freezes if enabled (there is often no other indication that such mods are incompatible), and also add support for quick-charge, overclocking (from original 1.4 to 1.84GHZ), and many other kernel dependant value-added features and abilities.

He also produced a number of ROM ports (RR, PAC, Slim, Tipsy, Bliss, AOKP, etc) as well as the only official ROM we enjoyed for some time in OctOS, but this was discontinued.

Following are a sampling of his announcements re. kernel updates - you'll get the picture:

Features in his later RedMI Soviet Kernel (I just found this):

https://xdaforums.com/redmi-note-4/...pment/kernel-soviet-star-kernel-mido-t3671011

The success with [MENTION=6864096]NATO66613[/MENTION]'s 'Soviet' kernels, which are simply modifications based on the work of others, is why I suggested It would be great if someone with more knowledge could shed light on sources for such enhancements, and how they can be added to our kernel. ( [MENTION=6864096]NATO66613[/MENTION] - be great if you could comment, especially if you know anything about MediaTek devices).

Ah. Understand. :) PW

[Android General] RBraverman:
I have been looking everywhere for a week or two and have not found a solution to a simple (I thought) problem- so here I am in one of the more informative, intelligent forums... ....

I'm trying to get a couple of disparate devices setup so that my PC can see the ext_SDCard on each as a drive (letter) IN Windows, so that I can use GoodSync, or an equivalent (which I haven't found yet), to sync folders OTHER THAN photos, Camera, music etc.

.

On this unit with LineageOS 14.x I've tried a webdav server, ftpServer, both of which can be seem by G/S but the program, or any other for that matter, can not write to the card.

Nouget 7.1x on my T700 works with WebDav Server, but LineageOS 16.x on my Samsung S5 NOTHING and I mean NOTHING can even SEE the ext SDCard.

Ideas?
[Android General] RBraverman:
Thank you once again for help and a informative answer, I really appreciate you taking the time; firstly to help me back when I used Kingroot and tooted the unit, and now.

That was one of the first of MANY of the apps I tried to little avail. I did notice after 4.x that this was becoming a problem.

I suppose it became, in Googles eyes, myopic as they are, that it would save the less computer/device literate from themselves. I feel all warm and fuzzy they're looking out for me :p

I finally put V10 of Goodsync (can be obtained free at sharewareonsale.com, it's usually offered once a month) on top of V9.x and low and behold it has a MTP access option.

A bit of explanation, I have about 10+ gig of tech docs (believe it or not I've been IT since the late 70's and yes I am THAT old ...) that I update all the time on the desktop and like to carry (also a lot of medical docs for the wife). It would be a pain if I didn't/couldn't simply be able to copy of the new/changed docs. GoodSync is good at that, and keeping up my WebDav Server also synced.
[Android General] pndwal:
Are you referring to Universal USB Mass Storage enabler app here?

Yeah, you, me and others felt that way, but I think partly as we resist change.

After a sober examination of facts I've presented, googles ditching mass storage mode makes more sense - ie potential for data corruption (and litigation) especially with newer partioning regime (unified file system for /data & /sdcard etc) as well as other problems with handing off full block level access to SD, patent / royalty rights for FAT, benefits of using EXT4 / F2FS with android, implementation of security protocols (ie. F2FS encrypted adopted storage) becoming almost mandatory, and likely other concerns.

Great! Any apps not catering for MTP android handling are clearly becoming fossilised IMHO. Hope you don't have issues with individual file handoff in this mode (still a bit of an issue / downside).

FWIW I'm old too, but an enthusiast only - no IT experience. However, I've gained a little useful insight over the years. Happy if it helped. PW

Hey guys,

i'm looking for any TB3-850F stock firmware - every link i tried is offline :(

I wiped the complete internal storage using TWRP (i know.. my bad...) and i'm now stuck on the lenovo screen. TWRP/recovery or Fastboot won't come up, so i think unbricking the device with any stock firmware is the only solution.

Thanks!
[Android General] pndwal:
Wow, looks like russian lenovo forum links are dead!

What partitions exactly have you wiped with twrp?

Google may get you somewhere - found this link quickly - download starts, but I didn't complete and can't vouch for file authenticity - try it at own risk:

https://gsm-firmware.com/index.php?a=downloads&b=folder&id=9408

PS. be very careful what you wipe with sp flash tool, as some partitions can't be restored even with full stock ROM. TWRP generally doesn't let this happen. PW
[Android General] limited_imagination:
I have a copy of the stock firmware that can be used with an included version of the SP Flash Tool, TB3-850F_S100030_161209_ROW. I must have got it from the Russian forum when the links were live.

But my Google Drive is very full these days, so I'm not keen to post it & host it.

Earlier, [MENTION=4220142]RBraverman[/MENTION] offered to host files, so maybe he could do it. Actually, I think he may have a copy of that stock rom handy anyway, because he reflashed his device with the stock rom a few months ago with sp flash tool, IIRC.

[MENTION=4220142]RBraverman[/MENTION], if you have on-line space to host the rom, and you don't have a copy handy, then hit me up by PM and I will get a copy to you.

Then [MENTION=5241097]lippmannmax[/MENTION] and others in future can get up & running again.
[Android General] Viva La Android R.I.P.:
To the best of my knowledge, this is the most current Android 6.0 stock ROM for the Lenovo Tab3 TB3-850F, built from the most current firmware version. To specify, this firmware is for the "81 Hardware Code" variant. (The Lenovo/Moto Smart Assistant recognizes two variants of the TB3-850F -- the "80" and the "81" "Hardware Code" models. To verify your variant, check the last two digits of your S/N, which will be either 80 or 81. The 81 variant uses the MT6735m SoC, while the 80 variant is believed to run on the very similar MT8161. While the specs of the two variants are almost exactly identical, the Moto/Lenovo Smart Assistant does distinguish two variants -- and while I cannot confirm whether there is a firmware difference between the two models, I do want to make note of the confirmed OEM distinction.)

Also, please note that I did not create this stock ROM installer. Credit should go to the author listed in the TWRP installation script. (The name I cannot recall off top).

Another Boot Loop Fix

I followed these instructions, but I threw myself into a boot loop because I rushed and did fastboot flash recovery twrp.img after I unlocked the bootloader. I obviously panicked, but I was able to fix it by flashing the stock recovery on the tablet. When it was in the boot loop, I clicked the volume down and power button and ran adb reboot bootloader in terminal until it was able to boot back into fastboot. Then I just ran fastboot flash recovery recovery.img

I'm unable to post any links in this post since I'm new, but you can probably find the stock recovery img in one of these posts or google it. If you're still having trouble, message me, and I'll make sure you get it.

After I got the tablet up and running, I followed the instructions more closely, and I got it up and running. Thanks so much for this post!

[Android General] Viva La Android R.I.P.:
Ok. So you are stuck in a boot loop. Here is what I would recommend. Follow these steps:

NOTE: First and foremost, ensure that your device is the Lenovo Tab3 8 with model number TB3-850F or TB3-850M.

1. Save the custom ROM to a micro SD card and insert it into the micro SD card slot on your tablet;

2. Boot your tablet into TWRP;

3. On the main/home screen of TWRP, select WIPE and then select the FORMAT DATA option. Return to TWRP main screen, select REBOOT and then RECOVERY;

4. Once TWRP reboots, select WIPE again; choose System, Cache, Dalvik Cache;

5. Once the wipe completes, return to TWRP's main screen, select INSTALL and navigate to the saved location of the custom ROM zip on external storage. Commence with installation;

6. Once installation is complete, return to the main TWRP screen, select REBOOT, then SYSTEM.

If these steps do not work, the next likely possibility is firmware related. It may be necessary to flash your tablet with the most current stock firmware package available using the SP Flash Tool and, once flashed, you then reinstall TWRP and the custom ROM again. Out of curiosity. and to avoid assumptions on my part, what is your model number? Can you confirm that you have the TB3-850F model tablet? In any event, I would like to ask for input from @pndwal or one of these other members who has experience with this tablet Feel free to chime in guys
[Android General] Crisdax:

[Android General] Viva La Android R.I.P.:
The Lenovo Tab3 8 isn't actually part of the Yoga tablet series as depicted in the video. Do you have the TB3-850F or the TB3-850M? I am now creating a restoration guide for the Tab3 8 using the LMSA Rescue utility for Windows. I should be done with it today and I will post a link here once finished. LMSA downloads the most current stock firmware and flashes it. Please confirm your model number.
[Android General] Crisdax:
my version the tablet is tab 3 850 f ... but this video is good
[Android General] Viva La Android R.I.P.:
Yes the video seems to cover the Lenovo TB3-850F, 850M and 850L, though there is a much simpler method. Thank you for clarifying your model.
[Android General] Viva La Android R.I.P.:
@Crisdax, after looking at your video link a second time, I realized that it references three models of the Lenovo Yoga Tab3: YT3-850F, YT3-850L and YT3-850M. So, the ROM referenced in that video is not for the Lenovo Tab3 8 (TB3-850F/M), nor is it compatible. There are some remarkable hardware differences between the Tab3 8 and the Yoga Tab3. Sorry I missed those details yesterday. I didn't see the YT3 nomenclature until I opened the link using the YouTube app. Attempting to install a Yoga ROM on the TB3-850F/M couid very well result in a bricked device. I will have my restoration guide for the TB3-850F/M finished and posted today.

Lenovo and Motorola are known for their oftentimes confusing and ambiguous device series names and model numbers, which can be haphazard and overlapping. You mentioned yesterday that the video was "good." I am assuming you meant that it worked on your device. If it did, you have a Yoga Tab3 versus the Tab3 8 for which this thread was originally created. I realize you have an 850F model. What I need is the first three letters/numbers, e.g. YT3-850F, TB3-850F. I am willing to wager that you have a Yoga series tablet, which explains why the LineageOS 14.1 ROM didn't work.
[Android General] Viva La Android R.I.P.:

Hi Viva La Android

I would be grateful for all files necessary to perform the steps in the guide (unlocking the bootloader, installing the correct twrp custom recovery and attaining root). I wonder if getting root with Magisk would be more suitable for this tab?

Soon after getting twrp installed and playing with root apps, I would really like to install the most stable LineageOS that there is (or equivalent custom ROM) so I can be freed from the Lenovo and Google spyware completely. Your thoughts on the most reliable ROM are welcome. It can be a minefield searching for up-to-date info, so I appreciate it.

RIP MotoJunkie01, and thanks for helping us.
[Android General] Viva La Android R.I.P.:
Greetings friend,

I have TWRP for the 850F which I'll share with you shortly. I recommend using TWRP to install the latest Magisk 23.0 root script. Magisk will remove dm-verity and, if you format data before installing Magisk, will also remove force encryption. But first things first, let me round up all the files you'll need to unlock your bootloader and install TWRP. Then we can tackle root. As far as custom ROMs go, unfortunately there isn't much available for the 850F. The LOS 14.1 ROM is stable and overall seems like a good custom ROM. I'm in the process of overhauling it a bit.

Ok, keep watch here and this evening sometime I'll be posting you some links to the files you'll need.
[Android General] Viva La Android R.I.P.:
Ok @comfortable, here is the unofficial TWRP v3.0.3-0 for the Tab3 8 (850F & 850M). https://drive.google.com/file/d/1-F34W9I8LxHabGmbMZEBy5C85UUE_45a/view?usp=drivesdk

This is the 15 Second ADB, Fastboot & device driver installer (v1.5.6, the latest version) for Windows 7, 8, 10 or 11 Beta. Just download this on your PC, install it, open it up and follow the prompts. When it asks if you want ADB system wide, select yes. Opt for the fastboot drivers as well, and finally, let the program install a USB device driver. If Lenovo is not included on the list of OEMs, just pick a Google device driver. Works fine.

This is Magisk v23 0 systemless root script. Install this from TWRP.

You got me looking over the rooting strategy for this tablet and it needs updating. I'm going to create an updated thread for Tab3 8 rooting using the Magisk root solution versus the deprecated SuperSU method.
[Android General] comfortable:
Fantastic. Thank you.
[Android General] Viva La Android R.I.P.:
Have you had any headway on rooting your device yet?
[Android General] comfortable:
Unfortunately, no success.

I get into Fastboot without issue, but after issuing the command to unlock the bootloader I see: waiting for any device on the computer. I tried first with Windows and then in Linux too. I tried 3 different USB ports and 3 different MicroUSB cables. Exact same result. Device is always detected in Windows and Linux, but both get waiting for any device when attemting to unlock the bootloader. I followed the instructions to the letter so it may be that my TB3-850F just won't co-operate.
[Android General] Viva La Android R.I.P.:
Your issue is almost certainly driver related. This is a fairly common problem that others have likewise encountered. One surefire way to get the correct fastboot drivers to configure properly is to install the Lenovo-Moto Rescue & Smart Assistant (LMSA). You won't actually have to use the LMSA as it will install drivers system wide that will enable fastboot communication. I'll get you a link for the latest LMSA release.
[Android General] Viva La Android R.I.P.:
I am fairly certain your are having fastboot driver issues. Try installing the Lenovo-Moto Rescue & Smart Assistant (LMSA). It will configure your fastboot drivers properly. Here is a link https://support.lenovo.com/us/en/downloads/ds101291-rescue-and-smart-assistant-lmsa

This is a Windows utility. Install it on your PC or laptop and it will configure your fastboot drivers properly. You won't need to actually use LMSA, as it installs the drivers system-wide. But, it couldn't hurt to let LMSA run in the background while you are using the fastboot protocol.
