VK810 4.2.2 'Device not found' error in Windows when attempting to install TWRP

I have a client who received a free VK810 when upgrading their phone. The stock firmware is horrible, and I was able to find a pure android version, but I can't seem to install TWRP.

I am usually pretty good, and have installed custom recovery on over 20 phones.

What am I doing wrong?
[G Pad 8.3 Q&A, Help & Troubleshooting] Hnk1:
Which firmware you are on currently? You'll need to downgrade your a boot to 4.2.2 to make it work.

Quote me if you are still confused and I'll put up a guide.
[G Pad 8.3 Q&A, Help & Troubleshooting] SidedX:
Well, when I got it it was 4.4.2 and I ended up bricking it completely attempting to do anything. Verizon had some kind of lock so it just said 'Boot error" etc.

I used the LG Flash Tool which was in Korean and managed to get a KDZ file to restore the device. Even though it had been purchased at 4.4.2, it is now reporting to be 4.2.2.

So I downloaded TWRP, and I assume I have to first use Stumproot, and then afterwards, I can't for the life of me figure out how to get TWRP on the device! With the Nexus I use the toolkit, and with the Galaxy series I use Odin, but the instructions for this non-common device seem to be running a command line and using CD to change directory to the Loki flash, but even after I used the '15 second ADB driver install' I get stuck with the device not found.

Thank you for your help. :D

Whoops, didn't see this was already replied to. Delete. :)
[Moto G General] Chris Kurisu:
My backup is well over 2gb. When I follow this process I do not have to store anything on my device other than a single 162mb zip file, that's a nearly 92% reduction!

As all owners know, the Moto G original is limited to 8gb of storage space. And I can't afford the space to store a complete backup on my device. Since storage space is more important to me than expediency I always park my backup on a laptop and on the cloud.

But my penchant for messing with things cannot be relied upon to wait until my lappy is nearby. So I keep an installation file for the lightest ROM that I could find for my device (it just so happens that it's also my daily driver, but that's not a requirement). I use that ROM to get me back online, then I download and restore my full backup. This process replaces my very large backup for a significantly smaller file.

The individual parts of this process are nothing new, but when combined may be helpful for those who are similarly situated. I cannot think of any reason why this wouldn't work for any device out there, regardless of the manufacturer, OS version, etc.

Pardon me if this has already been written up but I had not seen anything similar, at least not in one place.

Disclaimer: It is entirely your choice to try this. Anytime you alter your device you assume complete responsibility.

Note: A custom recovery is required.

Backup process.

1. Create a full backup using your preferred backup application.

2. Compress your backup (I use Nandroid Manager).

3. Upload your backup to the cloud (I use ES File Explorer).

4. Delete both the backup and the compressed zip from your device.

5. Download the lightest ROM for your device (I use Slimkat, it's only 162mb). I'll refer to this your initial ROM.

6. Enjoy the additional space and tinker away!

Note: You can use Slim as your initial ROM even if it is not your daily driver. The only reason for the initial ROM is to gain access to the full backup on the cloud.

Restoration process.

1. Boot into Recovery and prepare your device for a new ROM.

2. Install the initial ROM, boot and connect to Wifi.

3. Download your compressed backup from your cloud.

4. Move that file to your backup app's restoration folder and extract.

5. Reboot into recovery and restore your full backup.

6. After booting up, delete the backup and the uncompressed folder.

7. Verify that your initial ROM remains so that you can repeat this recovery processs the next time.

Notes:

This process does not involve gapps, and was performed using only the latest stable Slimkat installation. If you choose to use a different initial ROM you should verify that it will provide similar capabilities, specifically the ability to extract a compressed backup.

Since only minimal functions are required of the operating system someone more knowledgeable than me could greatly decrease the size of Slimkat zip file by eliminating superfluous apps and files.

You are free to share this in any way you want, I take no credit for anything related to this post. I thank the entire community for the selfless and helpful nature.

[Galaxy Note 4 Q&A, Help & Troubleshooting] torquadon:
I have strange touchscreen problem on my sm-n910f. After I flashed custom recovery and one of the custom roms my touchscreen stopped working properly, even if I revert to stock. It looks like touch surface became smaller, right and bottom part of the screen doesn't work any more. Phone seems to use smaller surface for touch, so to press very bottom icon I need to press 1-2cm above it. It behaves the same in any rom and any recovery. See photos, I activated show touches in dev options. I try to look if anyone had the same problem, but I couldn't find anything. Any ideas?

I forgot to add that spen works perfectly fine.
[Galaxy Note 4 Q&A, Help & Troubleshooting] torquadon:
Well I know what I did wrong so just in case someone else has the same problem: I flashed wrong recovery, one for n915f (no idea how I managed to get that file instead of proper one). Funny enough reflashing good one or flashing stock rom doesn't solve my problem. Over the weekend I will go to Samsung shop, hope they can help me.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Ausboy 2011:

[Galaxy Note 4 Q&A, Help & Troubleshooting] torquadon:
I tried to flash original firmware and two custom roms, no change unfortunately. I also believe it is not hardware fault, but I have no idea how to fix it.
[Galaxy Note 4 Q&A, Help & Troubleshooting] torquadon:
I love Samsung warranty policy in the UK, 28 days from purchase date they replace faulty device without asking for a reason, so I got mine replaced. Pure luck.

I still believe it would be know if what I have done is reversible. I understand why flashing wrong recovery is messing with graphic driver, but I would like to know why flashing proper one doesn't solve it.

I would appreciate if someone could share some light on that matter.
[Galaxy Note 4 Q&A, Help & Troubleshooting] iridaki:
Probably has to do something with partition size. When you flashed the wrong recovery, a repartition was done and it messed up your device. Flashing the right one in a messed up partition did not solve the problem. Perhaps if you had tried to flash the appropriate PIT File for your device, the problem would have been solved. But, in the future, the safest option is to be extra careful about which files you flash. Glad you got it sorted out!
[Galaxy Note 4 Q&A, Help & Troubleshooting] torquadon:
I tried PIT file too, no go :( As I said my problem is sorted, but fact that I do not know if it could have been resolved without replacement bothers me a little bit :)
[Galaxy Note 4 Q&A, Help & Troubleshooting] iridaki:
If the PIT file didn't work, then it seems that the replacement was the only way to go.

[Shield Tablet Q&A, Help & Troubleshooting] xerotheory:
Recently purchased and have been liking the tablet besides it's internet performance. I immedietly updated the tablet to lollipop out of the box so I was not able to test it's network on kitkat.

Since using the tablet I've noticed a variety of issues:

1. Opening webpages in chrome is substantially slower than on my phone (htc one m8 running fairly stock sense rom), with longer load times and occasional hangs on page loads that require a refresh to complete.

2. When using either reddit is fun golden or reddit news pro, subreddits take longer to load than on the M8 as well.

3. Slow Google play downloads. I'm not sure if this is just a Play store being slow or truly an issue with my device. Occasionally if i have multiple downloads or updates qeued it will finish one and just sit on trying to start the next one without actually doing it.

I have been having these issues on two different home networks with different routers, different ISPs, and different cities. Interestingly though, when running the Speed Test app, the tablet does better than the M8 and comes back testing perfectly fine.

Any suggestions as to what i can do to get to the bottom of this? Any diagnostic test I can do? Any setting? Has anyone else been having these issues and is this just an issue with the lollipop update?

Thank you in advance!
[Shield Tablet Q&A, Help & Troubleshooting] manigault:
Correct me if I'm wrong, but I think any OTA update is a "dirty flash". I also was having many issues that included complete freezing up of the tablet. You having updated out of the box could be different (I had a bunch of apps installed when I updated), but I think most of my issues were solved with a factory reset. ??

[Nexus 5 Q&A, Help & Troubleshooting] sshanky:
Hello everyone,

I wanted to move all the contents of one Nexus 5 to another one, but I'm learning that I might have failed to properly account for the EFS partition and now my phone has an IMEI of "0" and won't register with T-Mobile. I'm not sure how to restore it at this point, as no backup of this phone was ever taken (it was stock).

Can anyone point me in the right direction? I did find someone else who had this problem here:

http://android.stackexchange.com/questions/85807/nexus-5-imei-0-how-to-restore-imei

and that led me to

http://xdaforums.com/google-nexus-5/development/modem-nexus-5-flashable-modems-efs-t2514095

which had a script for, I think, helping to download or export the EFS information. Problem is that this phone doesn't have any IMEI info any longer! I do have another N5 I can use if needed to extract what I need and then perhaps I can edit the IMEI manually?

Thanks a lot everyone

Not sure if it's possible but you could try... I'm thinking it may be possible to edit the nandroid with the EFS part to the IMEI of the 2nd device. Your device should have the IMEI sticker on the back, so you could try to replace the IMEI in the nandroid to the one on the back of the phone. Hopefully you understand what I'm trying to stay and good luck with it.

still, recovering /efs... forget copying it from another device.. just flash factory images.
[Nexus 5 Q&A, Help & Troubleshooting] sshanky:
I've tried that twice already. Factory images would be awesome for me if they worked. After I do it, the IMEI is still zero.

It seems that everyone feels I am trying to do something illegal. On the contrary, I'm just trying to get the phone to work with its own IMEI short of sending it back to LG, which I will do if I have to, but I thought this would be a lot easier to do given that I have two Nexus 5s right hear to play with, and the IMEI stickers still on both of the phones. I read that on the Nexus 5 that stuff is stored in EFS, and erasing it was a total noob mistake (even though I've been flashing phone ROMs for years and years now), since I never suspected that IMEI info would be in non-hardware areas of the phone. Live and learn, I guess.
[Nexus 5 Q&A, Help & Troubleshooting] sshanky:
I will do it again. I flashed factory quite a few times with no luck. I then installed TWRP again just in case I find a way to recover or reinstall the EFS partition. So that's the current state of the phone.

I just checked that out, and it looks interesting. However, someone asked if it rebuilds EFS and the answer was "no".
