[Android Q&A, Help & Troubleshooting] JOAOFRS:
someone have lenovo p8 (tab 3 8 plus tb-8703F) ?
[Android Q&A, Help & Troubleshooting] limited_imagination:
Hi, I have been trying to use this same source code to compile a kernel for the 850F.

I am surprised and pleased that you were able to compile a kernel with this source code, because it looks to me like it is missing a lot of files.

Or maybe I am going about it the wrong way, and you could give me a quick pointer.

I *think* the correct defconfig file to use from the source code is found at /TB6735P1_64/alps/kernel-3.18/arch/arm64/configs/lcsh8735m_6_co_defconfig.

And I am pretty sure the correct toolchain to use is the 4.9 version, because from a root terminal on the 850F, I ran "strings /system/lib/libeffects.so|grep -I gcc", and it returned, "GCC: (GNU) 4.9.x-google 20140827 (prerelease)"

But what is stopping any progress for me is that there are no makefile, kconfig, or kbuild files in the source code folders for the arm64 kernel.

So I can't compile anything.

Starting in the source code directory /TB6735P1_64/alps/kernel-3.18/arch/arm64/kernel, using a "make" command results in a "Nothing to be done for 'lcsh8735m_6_co_defconfig'".

If I try "make menuconfig", I get "No rule to make target 'menuconfig'. Stop."

I have tried changing into various other directories in the source code, before executing the "make", but they are all dead ends so far.

Were you somehow able to generate these missing files in the source code, maybe from the mkimage tool, or maybe from another generic aarch64 source code, or am I missing something else obvious?

I would appreciate any hints you could provide.
[Android Q&A, Help & Troubleshooting] Fran89.:
Wow it's been a while. Yeah I remember being able to compile one kernel image, but I don't really remember how. I think I have it here:

https://github.com/Fran89/android_kernel_lenovo_tab3.

I may have just merged it with a branch or something like this one (you know put the options from the defconfig into the other one):

https://github.com/Fran89/android_kernel_mediatek2

I also have the rest:

https://github.com/Fran89/android_tab3_manifest

https://github.com/Fran89/android_device_lenovo_tab3

https://github.com/Fran89/android_vendor_lenovo_tab3

Although I'll be frank, it did not really compile very well and I used a big machine at my university to even try. I got so busy with my thesis I forgot where I left off. I'll see if the files are still there on monday and give you and update. I'll be great if this can be done. I remember I really wanted to compile LineageOS for it with an very optimized kernel (this tablet can be slow sometimes, tho very battery friendly).

You might want to create your own repositories and start cloning if you want to compile an android image for it, if all you want is a better kernel then I'll see what I can do.

Cheers,

Fran89

** Also I remember that there is some stuff in the lenovo files that had to be compiled and placed in the image but I don't remember what it was exactly. **
[Android Q&A, Help & Troubleshooting] limited_imagination:
Excellent, thanks very much for going back to look at your files.

You have a more ambitious plan than I do for the kernel, because I was only hoping to compile a driver module to use an FTDI serial USB cable with this tablet.

It would be very cool if you achieved your own plans for an optimized kernel for the device.

I went down this road once before on a different device, compiling a kernel to get a loadable FTDI driver module for my Acer B1-750. But that reached a dead end for a different reason. I seemed to be able to compile the source code and I got the ftdi_sio.ko module built, but when I actually tried to load the module, I got the sad message

insmod: init_module 'ftdi_sio.ko' failed (Required key not available)"

So as I now understand it, without the Acer signed security key during the compile process, my ftdi_sio.ko module is useless. I never did try to flash my entire kernel build to the device, because I had hacked a lot of things up in the source code to just get the FTDI module to compile, and couldn't trust the full kernel build. It seems pretty common for manufacturers to publish less than the full source code they that actually used on their devices. Where there were missing dependencies in the Acer source code, I just deleted any references to them, instead of trying to merge them with a known good source code, as you did. That allowed the compile process to stagger onwards towards completing its highly questionable result. Doubtless, flashing the resulting hacked up kernel compiled from this butchery would have bricked the device, but I figured that I had about a 50% chance of getting a working driver module that I could load with an insmod command. With the security key problem, I guess I will never know.

I wonder if I will hit the same dead end on the TB3 850F, if I can actually get to the point of compiling a loadable ftdi_sio.ko module for it.

Anyway, good luck with your thesis.
[Android Q&A, Help & Troubleshooting] limited_imagination:
I had some time to fool with this today, and the source code that you posted as android_kernel_lenovo_tab3 worked well to build kernel modules, with one small tweak.

I used the "make" command for the lcsh8735m_6_co_defconfig file, and generated a .config file.

Then I used the "make menuconfig" command and got the full meal deal of configuration options, including adding the FTDI serial usb driver.

Then I used the "make modules" command, but it returned with an error that "/android_kernel_lenovo_tab3/tools/tools/ does not exist. Stop."

I looked into the other source code you posted, android_kernel_mediatek2, and found a second "tools" folder with a file labeled "Empty", so I pasted it into the /android_kernel_lenovo_tab3/tools/ folder, and re-ran "make modules".

It worked, and generated modules for me.

As I suspected, nothing comes easy, and when I tried to "insmod" the modules on the Tab3, I got the error:

insmod: failed to load ftdi_sio.ko: Function not implemented

If I try "lsmod", I get "No file /proc/modules", and if I try "modprobe", I get "can't change directory to '/system/lib/modules': No such file or directory".

I think this all means that the factory rom on the device does not have loadable module support enabled.

Did you ever flash your device with the kernel that you built?

I am toying with doing that, if only to enable loadable module support, now that you have posted a mostly complete source code to work from.

Thanks again.

Did you notice TB3-850M now has working ported Lineage OS 14.1 (not bug free yet)? I imagine it would be easy to get this to install / boot on TB3-850F as TB3-850M is a close cousin (with SIM support),and I understand critical hardware / partitioning is essentially the same. (Others report running TB3-850F firmware on TB3-850M and seem only to lack SIM support).

[Nexus 6  General] geokhentix:
Its been reported that merely having an unlocked bootloader now trips safetynet. Google has officially turned their backs on developers and enthusiasts.

I never had a problem with xposed or magisk tripping safetynet; but an unlocked bootloader is by no means a security risk. So I'm not happy having to choose between snapchat and an unlocked bootloader.

Sources: https://www.reddit.com/r/Android/comments/587ss9/psa_android_safetynet_now_tripped_by_unlocking/

Well RIP AP....

[Nexus 6  General] sgloki77:
can confirm, I have unrooted stock 7.0 as my primary on multirom and is tripping safetynet, no more AP for me I guess since I'm NOT locking the bootloader, nice play Google
[Nexus 6  General] geokhentix:
IIRC chainfire DID warn us about this..saying if we keep trying to hide root, they'll keep trying to make it harder for us to do so.

Doing it to the pixel? Fine..but to a nexus phone? Kinda murders the whole selling point of Nexus.

Either way elgoog has been making some really odd decisions this past month or so.
[Nexus 6  General] biggiesmalls657:
I have an unlocked bootloader with everything stock and no root and I got past safety net for Pokemon Go.
[Nexus 6  General] geokhentix:
Last I heard pokemon go isn't working with safetynet properly right now. Download SafetyNet Helper Sample from the PlayStore, it'll tell you whether you pass or not.

[Nexus 6  General] holeindalip:

[Nexus 6  General] geokhentix:
Yeah, that one isn't a part of this as its not unlockable. I'm talking about the Google Pixel.

This f's people who just want to install the latest factory image too; non power users who don't root and just want the latest OS..considering you need an unlocked boot loader to flash the images.
[Nexus 6  General] holeindalip:
Not if you side load the latest ota files posted the same day:good::svetius:
[Nexus 6  General] Kariharri:
By the way, does re-locking bootloader wipe data or internal? Factory image page says that "Locking bootloader will wipe the data on some devices. ".

You can still customize. You just can't do crap that you probably shouldn't be worrying about anyway. Android pay is a sham, since your credit card has an RF chip in it that works on the same scanner... but ONE FEWER companies get to track all your purchases when you use it since it leaves google out of the loop.
[Nexus 6  General] geokhentix:
Indeed; also as long as you log into Snapchat once before you install root, it seems to continue to work after root / magisk installation.
[Nexus 6  General] pharpe:
I'm on 7.0 stock, rooted and unlocked bootloader and snapchat works fine.
[Nexus 6  General] holeindalip:
I just want to say that Snapchat is one of the worst coded apps ever

For Snapchat to work, you have to login before rooting your device, just don't log out lol
[Nexus 6  General] geokhentix:

[Nexus 6  General] doitright:
I wonder what the hook is that it uses to check if the bootloader is locked...? It *must* go through the kernel, so maybe this is as simple as telling the kernel to LIE about it.

Well, that is simple conceptually, but not necessarily *easy* to implement.

[Galaxy S 4 Q&A, Help & Troubleshooting] vaibhav.2kumar:
I hope it was possible.but let me make u understand my points:-

1.There is no service center which is accepting an old phone like s4,they all are saying we can't serve this phone anymore.

2.Its out of warranty so even if it was possible it would cost around 40$ here which i don't think is a possible amount to be paid for(considering point 3).

3. The only hope i get is go out and find some local service center who could repair this but I've searched the whole city and the situation is the best guy i found said it cant be done I could replace your motherboard for 40$.

So the only option i get is get someone's s4 efs backup and restore it manually by editing through hex editor and restoring my stock imei. So please help me.
[Galaxy S 4 Q&A, Help & Troubleshooting] Strephon Alkhalikoi:
[MENTION=6125946]vaibhav.2kumar[/MENTION]: Restating your request isn't going to help you any. The EFS partition contains the IMEI of the phone, although nv_data.bin is now stored elsewhere. If one of the forum members were to offer their EFS, they would be committing an illegal act. This site is hosted in the United States, and in the United States cloning an IMEI is illegal. Period. The person offering the EFS would at best be banned, and at worst open up XDA to legal action. Thus no one can provide you a copy of their EFS partition.

I seriously cannot believe that Samsung service centers are unwilling to service the S4. Especially as in the United States they were still available for purchase through prepaid carriers such as Straight Talk up until the end of last year and possibly into the early portion of this year. So I have to question whether you truly tried to get this device serviced, which is what you need to do, or are trying to con someone out of their IMEI so a blacklisted phone can be used again.
[Galaxy S 4 Q&A, Help & Troubleshooting] vaibhav.2kumar:
Maybe if i cant get your s4's efs. But i can demand help from you I'll show you my s4's bill my id proof and my s4's box and you can compare all those imei's and thus help me in restoring my imei by changing your efs backup at least and by the way i dont live in us. I live in india for your details. If you could, please help me get my phone's imei back with legal actions i would really be helpful of you.

PS. Yes I've tried all the service centers in my city.period.
[Galaxy S 4 Q&A, Help & Troubleshooting] Strephon Alkhalikoi:
Clearly you are not quite comprehending what is being said. I'll try and simplify things for you.

1. Demanding help only makes readers not want to help you.

2. If none of the Samsung authorized service centers in your home city are willing to do the work, start looking outside the city.

3. The only legal option is to send your device to a service center.

If the service centers are truly unwilling to service the S4 (highly doubtful), then you're going to be purchasing a newer device.
