I've been trying to figure this out for a while, and I have made some headway but I think I need to make custom build. If anyone could point me in a direction, it would be super helpful. I have a few ELO ESY15i1 android computers. They are EOL now, and only supported up to kitkat. ELO does not release their kernel source, but I do have their peripherals.
This is how far I have got with this thing, and what I was able to do/determine.
After a bunch of digging, I'm pretty sure that this thing is just a modified S4 i9505. Hardware specs seem to match, outside of the CPU only being 1.7 instead of 1.9ghz. I'm *assuming* that they have down clocked it maybe? The first unit I was working with, apparently had a bricked recovery (had bough it 2nd hand). I was able to boot it into TWRP using the jfltexx image, but I would get no picture. I know it was booted because I could access TWRP via cmd, and it was giving me responses back.
I was able to root it in a very round about way. Since I do not have any volume buttons, I'm limited to adb etc. I was able to root it with iRoot, convert that to supersu, and eventually get flashfire to install. I could finally access almost everything I needed. At some point, I got it stuck in a mode where "QHUSB_DLOAD" was shown to me, with a folder called "image" which I took a copy of. Any google results with that, was just people who had bricked their device, I was able to boot in and out of this, so I'm not sure what was going on or broken.
Here is what the device props listed out: hXXps://pastebin.XXX/FtgQ0DUE
This is the mobilodin report: hXXps://pastebin.XXX/BZrDAFg4
Finally, the "image" I copied: hXXps://anonfiles.XXX/lcQ7RfJ8o0/ESY15i1-image_rar
(sorry can't post links)
The first unit I was working on, I gave to a buddy to mess around with. The 2nd one I have, I have now bricked and it is officially stuck in the "QHUSB_DLOAD" mode. I made a poor choice, and modified the i9505 "updater-script" in lineage-17.1-20200723-nightly-jfltexx-signed to include my "msm8960" device. I flashed it via FlashFire which did go through, just bricked me in the process.
I had a samsung download jig, but I can't find it anywhere, so I have a new one on order. I'm too lazy to cut up a micro usb plug and make one. I have yet to get odin to recognize it at all, or get it into download mode. When I try over adb, it will reboot, try to go in some mode, then reboot again back to the rom.
Any input / help would be greatly appreciated. These machines are super cheap on ebay, the only problem is being stuck on kitkat. I can think of loads of things to use these for, doesn't look like anyone has tried to do anything with them. From all my searching I just found one guy who was trying to root one, and that was about it.
Hi,
I have one 22 inch unit, which I'd like to use with monitoring system and some else, but I need android version with multi windows support, so I'd like to ask you if you succeed with installing new ROM ?
Thanks in advance for reply

Well, I've been dinking around with it again, I think I have the HW figured out. I'm pretty sure it's an LG Optimus G, LGE970 is what I'm trying.
I was able to take the stock "ATT-Stock-E97020j" non KDZ zip, pull the boot.img off of it, and flash that.
Now when I connect to my computer, I'm getting LGE Androidnet for Diagnostics, and LGE Androidnet USB serial, as 2 devices.
Just keeps hanging right away when I try and flash the KDZ.

OK. I think I've done my due diligence. I've scrubbed the forums for 2 days, I've googled it and I still can't figure out what I'm doing wrong.
Friend gives me this rooted LG OGP. Awsome! Works great! Then AT&T or LG sends an OTA update that bricks it :crying:. Read Aryan1312's sticky thread in this forum and get all pieces together. By now I have the 3.8.1 drivers AND the newest 3.10.1 drivers, LGFlashTool 1.8.1.1023, along with the newest 10P TOT file. I got the Flashtool to stop asking for PW and I think I'm ready to go.
But then . . . Plug my phone in and Device Management doesn't know what to do with phone. Reinstall drivers pack from LG website. Still no dice. Hmm. Phone is in Team Win Recovery Project v2.6.3.0 recovery screen (I guess that's what it's called) and computer doesn't know what to make of it. Hmm.
Maybe I can put it onto a microSD card and copy stuff over to phone? Maybe flash a different ROM through TWRP? Let's try that. I copy files over to the external SD card, put it into the phone, restart phone, hello TWRP, Advanced-File Manager option, WHY CAN'T YOU SEE THE EXTERNAL SDCARD??? Isn't it supposed to be there under /extSD?? It's time to ask for help.
Question: How do I get my Win7 PC to see the phone as a removable drive/external drive/whatever you call it so that I can get this info over?
I know that I have to change Port #'s after Win7 sees the phone. I just can't get there . . . yet.
- What I've tried:
Reinstalled drivers (both versions) and restarted between trying to plug phone in.
Tried installing phone drivers manually. Still doesn't mount as external HD as far as Win7 is concerned.
Called friend to ask his opinion. He doesn't remember and tries to tell me this is why Apple is "better".
Scoured the web to see what to do. Found articles about this same thing happening and all point to Stickied Post on this XDA forum
I did RTFM and am still lost.
---- Sorry for the long post, I just thought that people who wouldn't mind helping would appreciate the extra info.

1. Is the first pic with the phone connected to the pc?
2. If yes, have you tried to manually update drivers, while in device manager
3. I know that this is going to sound funny but have you tried a different USB port. The reason I ask is I had the same problem LG Optimus M and the phone was down for a couple of days. I tried everything and was about to call it quits but for some reason when I changed USB port the computer saw the phone and I was back in business. I am not saying that will 100% work but it is worth a try.

Yes I have. I think I did figure it out though. I put the device into "download mode" and my computer could see, and communicate, the phone.
To put my phone into "download mode" I did the following:
I connected the phone to the computer physically with USB cable
I turned phone off.
I pressed BOTH volume buttons and held the power button while phone was attached to computer.
With BOTH volume buttons still pressed, I released the power button.
The phone screen was black with a little dialog box in the middle saying "download mode"
I could then use LGFlash Tools to flash Stock AT&T TOT file back into phone. Took 519 seconds to complete the stock flash.
New problem arises, After flash, I do NOT have any 3G/4G signal. I can use the phone to make and receive phone calls and text messages, but I CANNOT use mobile internet unless I have it connected via wifi.
I installed the Debloated ROM and "tried" to flash 980 Baseband.zip but when I tried to install baseband, CWM gave me a permission error and said install failed. I haven't been able to use mobile internet since. Any help???
-- Again, sorry for the lengthy post. I figured that I might not be the only person who has gone through this. I see a lot of viewers to the thread so I think other people might be having same troubles as me.

It sound like you need to manually set the APN. Do a Search for your provider.. ie AT&T T-Mobile the setting is under Network/Tethering & Networks/ Mobile networks/ Access point name/ Hit Menu Button and New APN
You are the MAN / WOMAN!! Thanks for the help. That fixed it.
For posterity and to help another "noob" stuck in my case later (maybe months down the line)
This is what I've done up until now in plain text:
Used LGFlashtool to flash AT&T stock "10k" build
Went into Settings Icon>General>Developer Options>check off "USB Debugging"
Used "E980 Universal Root" from forums to gain Root access (verified with "Root Checker" from Playstore)
Used FreeGee to get TWRP recovery installed (rebooted into recovery with "QuickReboot" from Playstore).
Used TWRP recovery to install "E980 Baseband.zip" from forums
Factory Reset
Setup new phone and input APN settings (located in Settings Icon>Networks>Tethering & Networks>Mobile networks>Access point names>Menu button "New APN"/input carrier values/Menu button "Save")
Now that I know how to get back here, I'm going to scrap the stock ROM and try to do this whole process with a custom ROM. . . and another flash-a-holic is born. The learning journey continues.
Welcome:beer:
*KCCO*2SHAYNEZ*E980*
That is what this forum is for.
I have been helped out a lot from the group and I just thought it was time to pay it back. It is good to hear that you got it up and running. But one last word of advise BACK UP, BACK UP, BACK UP, and when that is done, back up the back up to the computer.
I am at my wits end to try to repair my phone. It is softbricked and responds to download mode only.
I've had chat with xda members and read threads on it:
http://forum.xda-developers.com/chef-central/android/nand-write-start-fail-odin-soluction-t2851096
http://forum.xda-developers.com/galaxy-note-10-1/help/help-help-unbricking-galaxy-note-10-1-t2872125
and many others. in the end, my phone is still stuck with the NAND Write Start error with odin.
I know it happened after i tried creating a backup of my phone in recovery mode (phone was rooted with cf auto root and had a version of CWM on it). CWM gave me a warning about possibly bricking the phone, i agreed to the warning beacuse it always worked in the past, but when i rebooted, it was bricked this time.
this phone is not dead but samsung won't fix it beacuse it is rooted. I refuse to throw it away. I have read many people have it this error since kitkat 4.4 so surely there is a fix somewhere. I am hoping somebody will be more resourceful/experienced than i am.
I have tried changing to several different USB ports, without a hub, using original cables (bunch of different ones too) in many many different order and fashion. I tried enough variation to be convinced it is statistically impossible that all my hardware that was previously working for flashing has stopped working all at once. aka - it is not a usb port or data cable problem
may be related to data charging port on the phone though I highly suspect it given how it started.
I tried different roms, different versions of odin, i tried depackaging and repackaging roms, i simply do not know what to do anymore.
i tried reflashing with kies but kies just dies on me.
i tried flashing it with adb but adb won't even connect. when i plug the phone windows recognizes it and usb driver seems to work ok (not getting an error)
I have uninstalled and reinstalled drivers several times, rebooting in between installs. no difference.
i tried flashing different bootloaders as well as entire roms, no difference
I tried changing the pit file but that failed as well (odin couldn't even write the pit so my phone is not dead even if i failed pitting it)
i have access to both windows and ubuntu linux if it makes a difference.
Here are the terms of the bounty:
Price : 100$ (payable by paypal from eniac0 @ "some google mail domain starting with gm"
goal : find a fix that works on the latest firmware for SGH-i317M (Rogers, Canada)
how : i don't know but i need to be able to reproduce it. I am not new to flashing but anything advanced will need to be explained clearly.
I don't really know how this sorts of request usually turns out but i am serious. you even got my google mail address to bill me up if i fail to pay.
have you given a look at this thread? http://forum.xda-developers.com/showthread.php?t=2711825 it might give you some ideas to help you out. also did you try flashing a new recovery to see if you could at least get it to boot to that?
dont care about the bounty just trying to toss something out there that may help you
Did you ever try flashing the stock recovery - JUST the stock recovery - through Odin?
If not, grab the recovery.img and make your own tarball for Odin in Linux.
Hopefully that will flash and get you closer.

Since you mentioned Ubuntu, you can also try using heimdall instead of odin... http://glassechidna.com.au/heimdall/ . Unfortunately, I think it may be a hardware problem?
Since you are willing to pay to have it fixed, if all else fails, you can always send it off to http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-note-jtag-brick-repair/. It will actually be cheaper than what you are offering to pay ~$40 + shipping
good luck
Thanks all for your help, I've messed around and gotten no closer. I'm beginning to lean on a hardware failure, perhaps from the usb data port either that or the way bootloaders are packaged in kitkat 4.4 is different. which is why initially this thread gave me hope: http://forum.xda-developers.com/chef-central/android/nand-write-start-fail-odin-soluction-t2851096 but i tried far too many times now to believe I'm going to succeed. In fact, I've gotten confused as to what i tried, in which order, with which rom. I'm basically trying anything and that's a recipe for bricking the phone for good. so i've stopped.
I'll also thank kozmo21 for the link to the repair shop. i was unaware this existed, as a last resort I'll be sending them my phone. If it turns out they are able to repair it, I'll honor my word and give you something for having been part of the solution.

Have you tried going to sammobile and download the newest firmware and only flashing that in odin?
Use CF auto root. Put the phone in download mode and flash it in Odin. I soft bricked my phone and it fixed it.
Also this guy had great walk through videos on how to do everything you need.
http://www.rootjunky.com/samsung/samsung-galaxy-note-2/
If it works to fix your phone. Keep your money. I'll take the karma points for putting you on the correct path.

More than likely its a bootloader issue my phone did that and all i did was flash the bootloader then it worked again but hes done so much idk what he needs now that's y i said to try a firmware to see if that helps
Download toolkit and select option to push file into phone.
Download a ROM of your choosing, push it into your phone, restart in recovery mode and select file.
Update?
Did you get it fixed? Just my two cents, in case you didnt, I had a similar problem and alll I did to fix it was flash the JediMasterX2 ROM with CWM and everything worked out.
Good day my friends. This is my first post but i read these forums very often. I own a Digicel Dl750 (alcatel 4037a) which i would really appreciate some help with. I tried to flash my phone some time ago using a tutorial i found online since i couldn't find anything useful here (my go to source for these things). However, after trying to flash the rom and failing, i am stuck with a phone that won't respond to any input. COnnecting it with a usb simply gives me a white light on the phone, and device manager reads a "MTK usb port" device. it won't boot or anything else. Been trying to install some kind of recovery but i've had no luck so far. Is anyone here able to provide me with a backup of a working phone so i can fix mine please.
Edit Note1: After a bit more testing, I have pretty much confirmed that it is a problem with the preloader as the phone seems to completely skip the preloader when you connect it to the pc, and after a few seconds goes to the bootrom(?) instead. I am making this call based on the hardware ids show in device manager.

Well i was able to get an OSP dump which solved my problem. Not sure it would be of use to you though
Where can I get this dump at Denis?
Hey guys,
sorry if my english isn't right but I am so tired so now and so frustrated that I don't know what I could do.
The story is simple: I have a android head unit, running allwinner t3 (aka R40) with stock rom and stock recovery.
So far, there isn't any custom recovery available (I would like to create/compile CWM but CWM-Builder have some 502 Bad Gateways...) and the only way to root on 4.4.2 is with 360Root (On 6.0.1 for the newer Models only with Kingroot).
So far not bad but it takes a lot of patience sometimes and sometimes you can try over 1 week every day many hours and it still don't work!
So where do I need help? I want to add Root/SuperSU/... manually but I have many limitation.
First one is that I can only modify the system.img without any chmod and else (Maybe because I am using windows? Maybe because the Firmware has to be flashed while the Head Unit is powered off aka "Dead flash")
Secondly, ADB is not working, to be honest, the head unit act only as a receiver! It accepts any devices like Keyboard, UMTS/WCDMA Stick, USB Stick, ... but MTP fom HeadUnit or ADB, ... don't work. The only way for ADB is ADB over Wifi but I don't know whether it's good or bad. I saw that the USB is plugged into a slot which seems to be bend out, maybe they plugged it in wrong? I don't know how I can test that but I heard that connecting two devices with wrong polarity will break at least one of them!
Thirdly is, that I can't notice a difference between a rooted stock rom and a unrooted stock rom.
According to WinMerge, the rooted ROM have two new files (/etc/install-recovery.sh and /bin/su) but that's it!
If I transfer those files to my custom ROM with the same rooting app, it wont recognize them! I can try and try until I die.
And last, maybe worst, I can't just update something over. Every change outside the Android OS is mainly done by flashing the whole firmware! They changed that policy a little bit after Android 6.0.1 but this Android have the worst stability, worst GPS Modules and completely bricked Bluetooth! Also the stock recovery on 4.4.2 is useless, touch isn't working and the touch-buttons are also not working. I also tried to use a usb keyboard but also useless. Only the 6.0.1 stock recovery recognizes the touch screen and the touch-buttons but as I said, the Android 6 is terribly made...
I know what it sound like a noob and I didn't provided much information but I want to know whether someone can help me or want to help me... maybe someone say that I have to provide information xyz so yeah, feel free to ask
Best regards
Pascal
At what point did you install the ADB device drivers (kinda important) for your device, so that when you plugged it into anything, the thing could register you were plugging in the HeadUnit......

I've been all over the Internet trying to gain access to more information about how to repair my LG G4. Well... Let's start from the beginning.
Story
I have an LG G4, it's old and I've had it for over 4-5 years now... I can't exactly remember how long I had it for. It still works, just needs a new battery and cable (cats chewed the cable and batteries don't last when you forget to disconnect them from the device, leave it plugged in for weeks and let it completely die for longer then a week).
I recently saw a video about the Pine phone and the fact that it was able to run a linux mobile distribution and when I looked into installing a custom OS into LG G4, it was possible... If I manually ported it myself.
I actually got fairly far using my Xubuntu system with configuring and compiling, the trouble I ran into was that I couldn't root or fastboot my device.
So, now here's where the problem began, I have a LG G4 factory reset and when I load up the Recovery mode, it brings up the android guy with their chest open and an exclamation mark in a yellow triangle, no message. After attempting to boot into recovery mode, I wait a little while and the phone automatically resets back to normal. When I use ADB to force the phone into fast boot, it skips it and starts the phone normally.
Now I'm on a mission to find a way to either fix the boot or flash the firmware (in hopes that it fixes the boot/recovery).
I have already tried:
Installing LGFlashTool
Versions, 2.0.1.6, 2.0.1.9, Year: 2014 and 2.0.2.5. Other than year 2014, the other ones were installed from LGFlashTool.com
Since Xubuntu can't run these files properly, I just ran them on my wife's Windows computer
I installed the LG Mobile Drivers and LGFlashTool had registered that it was the correct DLL but, it didn't seem to find the phone
Year 2014 LGFlashTool had found the phone but, I may have had the incorrect kdz file.
The Flash starts and the phone goes to firmware update, but the phone stops at zero and sits there while the program crashes saying that there was an error (in which no means to read, understand or locate the description of this error) and to try again by unplugging and removing the battery.
This version was downloaded from xda-developers.com
Conclusion
Once I can get into fastboot, I'll be able to root my phone and attempt to install the mobile OS I have ready.
Otherwise, I think I might be able to install a microSD card with the OS but, I don't think that will work if I can't get into the option to boot from a separate location (I believe that's called fastboot). But, then again... I think the phone needs to be rooted first... Then that brings me to the previous issue.
Details and Information
The phone details (as far as I see) are:
When I remove the battery I can see:
FCC ID: ZMFH810
IC ID: 2703C-H812
Model Number: LG-H812
I'm not exactly sure what KDZ file I got but the name is: PR H810PR10a_02.kdz, I also have the _04.kdz
I'm using H815 as my compile for the mobile OS, I may switch to H810 when I get back to that point.
Useless information: I still have the original leather backing... Removed from the phone because I didn't like it. If I find it, I can ship it to someone.
That's about it... I am very terrible about research and using Google properly (I have no idea why, I think it's a terrible flaw to have but, I have it). So, if you find the solution by typing words I didn't use or finding a similar post, I am very sorry. Hope I have everything posted here to help solve the issue, linking to posts that can resolve the issue or posting questions on what I might be missing will help.
Thanks in advance for the support of this community,
Lilrock

Now I'm on a mission to find a way to either fix the boot or flash the firmware (in hopes that it fixes the boot/recovery).
I have already tried:
Installing LGFlashTool
Versions, 2.0.1.6, 2.0.1.9, Year: 2014 and 2.0.2.5. Other than year 2014, the other ones were installed from LGFlashTool.com
Since Xubuntu can't run these files properly, I just ran them on my wife's Windows computer
I installed the LG Mobile Drivers and LGFlashTool had registered that it was the correct DLL but, it didn't seem to find the phone
Year 2014 LGFlashTool had found the phone but, I may have had the incorrect kdz file.
The Flash starts and the phone goes to firmware update, but the phone stops at zero and sits there while the program crashes saying that there was an error (in which no means to read, understand or locate the description of this error) and to try again by unplugging and removing the battery.
This version was downloaded from xda-developers.com
Conclusion
Once I can get into fastboot, I'll be able to root my phone and attempt to install the mobile OS I have ready.
Otherwise, I think I might be able to install a microSD card with the OS but, I don't think that will work if I can't get into the option to boot from a separate location (I believe that's called fastboot). But, then again... I think the phone needs to be rooted first... Then that brings me to the previous issue.
Details and Information
The phone details (as far as I see) are:
When I remove the battery I can see:
FCC ID: ZMFH810
IC ID: 2703C-H812
Model Number: LG-H812
I'm not exactly sure what KDZ file I got but the name is: PR H810PR10a_02.kdz, I also have the _04.kdz
I'm using H815 as my compile for the mobile OS, I may switch to H810 when I get back to that point.
Useless information: I still have the original leather backing... Removed from the phone because I didn't like it. If I find it, I can ship it to someone.
That's about it... I am very terrible about research and using Google properly (I have no idea why, I think it's a terrible flaw to have but, I have it). So, if you find the solution by typing words I didn't use or finding a similar post, I am very sorry. Hope I have everything posted here to help solve the issue, linking to posts that can resolve the issue or posting questions on what I might be missing will help.
Thanks in advance for the support of this community,

Well first of all you need to unlock your phone. H812 can't be unlocked officially though. Check my sig for the only unofficial one. Once unlocked you can flash custom ROMs but first of all you should read about ARB (antirollback) also in my sig and ensure you understand the risks all this brings. Gl.

Thanks for the positive feedback, I will attempt to fix my phone with your solution. This phone is technically almost garbage and when I fully update the phone, it runs like trash. So, if I can install a custom ROM, it may run a little better or have the tools I would personally like in a phone.
I'll let you know the details of my attempt,

Thank you very much with your support. I was able to unlock, bootloader and install the image installer.
I'm on the verge of compiling and installing Ubuntu Touch on my LG G4 H812.
Hope you guys proceed with everything you're doing right!
