LG G2 stuck at 49% flash and other fun things... - G2 General

I'm writing this post to give back to the community...
I spent about collectively 9 hours trying to get my D803 to work. Was on 4.2 rooted, then went factory fresh using the LG Support Tool. Then updated to 4.4.2 using the same. Great, things work except in the stupid Bell D803 ROM the "I-won't-remember-your-wifi-settings" bug still exists (!!). I went to great lengths to try and edit the build.prop and finally was able to push.
Reboot, then all heck broke loose. Apparently it didn't like my modified build.prop.
TOP TIP: when you have a stable phone, install a custom recovery and do a backup (yes, requires root)
The phone would boot past the LG logo then a black screen with blinking green and blue. I tried many, many things like factory reset, flashing this and that. If you're reading this you'll probably be familiar... load the HTTP fake server, modify HOSTS file, run window enabler... etc. Ultimately these things either lead to a 4% fail or the usual 49% fail.
After 9 hours of futzing around I gave it to my buddy as he said "it can't be that stupid, the stock consumer tools should work". He spent about 3 hours messing about and gave up. In the meantime, I built a physical Windows XP 32-bit machine just in case the fault lies in my trying to use a VMware Fusion XP box on my Mac to do this.
Fast forward...
I'm only going to list the tools/items I used, not link them as I have no idea where they came from now. I'm sure you can Google each and see where and what they are required for.
Setup_LGFlashTool_1.5.10.1120.exe
MegaLock.dll (to, uh, "unlock" the tool above)
BIN_LGD803AT-00-V10c-RGS-CA-SEP-04-2013-32G.zip (this file is SPECIFIC for the D803 variant !!)
BELL_D803B10D_00.kdz (this file is SPECIFIC for my Bell D803 variant !!)
LGUP_8974.dll (this is EXTRACTED from the KDZ file)
General steps:
1. Install the LG Flash Tool
2. Overwrite megalock.dll
3. Download YOUR correct TOT (zipped up) file from (remove spaces): downloads. codefi.re/autoprime/LG/LG_G2
4. Unzip the TOT file from the zip and put it someplace you remember
5. Download YOUR correct KDZ file. There are various places but the EASIEST is to get it DIRECTLY from LG. There is a way to use your IMEI and plug it into a csmg.lgmobile.com URL in order to download it. Please search it.
6. EXTRACT the DZ and DLL file from the KDZ you downloaded. Please search this. I believe it was using a Python script.
7. Install the LG G2 drivers, I used: LGUnitedMobileDriver_S4981MAN38AP22_ML_WHQL_Ver_3.8.1-2.exe
8. Boot the phone into factory reset mode and wipe it. Search this.
9. Boot the phone into DOWNLOAD (or UPDATE FIRMWARE) mode. Search this.
10. In DEVICE MANAGER, change the LG device (under PORTS) to use port 41, then unplug and plug the phone back in.
The good part...
11. Launch the LG Flash Tool, click MANUAL, then put in the location of the DLL and TOT file from above in the right places.
12. The upper left corner box labelled COM41 should now say "READY!!".
13. Unplug the phone, wait 5 seconds, it should say waiting for connection
14. Plug it back in.
15. Should be flashing now, just wait.
Why am I writing this? It took far too long for me to figure this out. Unknowns or stumbles:
1. No one clearly said when to plug in the phone at the FlashTool screen. I tried having it plugged in to launch the tool, I tried waiting for READY!! then plugging it in then. It always just sat a 0%. I HAD to have it plugged in, get to READY!!, then replug. Maybe you need to do this as well.
2. Skip using the LG Mobile Support Tool doing the HTTP hacks etc. Just use the LG FlashTool and cut to the chase. Wasted SO much time trying different KDZ, support tools, etc.
3. MAYBE it was the VMware guest causing issues but unlikely because I got to the same stages as the physical machine... all I did different was replug it in.
4. Only ONE KDZ file got to 49%, all the others dumped me at 4% (probably citing incompatibility?). You MIGHT need to extract the DLL file from a known KDZ that works for you OR maybe the DLL file is the same across the identical hardware models (ie. Bell D803)? I don't know.
I think those are the only lessons learned but if there are any more, I'll drop them in later. I have to go install a custom recovery and find out how to modify that build.prop properly on 4.4.2...

tip dont ota on custom recovery if you do there is a fix already posted somewhere.
some fixed 49% by clearing system/data prior to flashing. Not sure, never encountered it myself.

Oh yeah. I encountered that and had to LiveCD a Ubuntu virtual machine and push the partitions... that one is straightforward to fix The PRO TIP on that one from me is to disable the notification of removable drives in Ubuntu or it will drive you nuts.

THANK YOU!!!! I did exactly the same thing as you by improperly editing the build.prop file trying to solve the WiFi password issue. I spent the last few days with futile attempts at the KDZ method. Your method worked first time. I am now able to boot into 4.2.2.
Were you able to solve the WiFi issue at all?

Viewpad 7e Official Update

I received one of these the other day and began to tinker. Rooted with Gingerbreak v1.2, installed the full market, and busybox. All with no problems. I would like to change a few other things but with out having CWM to make a backup, I am a little cautious. When I go into the FWUpdate, it tells me there is an update. I tracked down the file on the web, downloaded it ( all 300 megs worth) and have been looking at it. If anyone would be interested it this file for development purposes I could upload it or provide the link of where to get it from.
Ive downloaded it. So far it fixes bugs. But you have to use root explorer to clear the unwanted apps
Sent from my LG-P500 using XDA App
Well I started dissecting the update. Found it is still 2.3.1, it uses fuse to manage the file system, and has an updated recovery. The file system layouts are a little different than what I normally see on my Incredible. It has separate mbr, uboot, kernel, env, system, ramdisk, ect... I would really like to change the density but with out having adb working or a custom recovery, if I use a value that is not compatible I am in a world of hurt.
Yeah its still the same. For nw i currently waiting for cm7 for viewpad 7e. Btw the viewpad 7e isnt big and limited people.
Sent from my LG-P500 using XDA App
Granted it is not a XOOM or a Galaxy Tab, but I don't think it should be it should be overlooked for development. I am not much of a programmer, but I do like to try. If a current developer could give some guidance as to how to build a custom recovery that would be beneficial.
Andy try power off the vp7e and then hold the power, volume
Up and down button. It resets my tablet.
Sent from my LG-P500 using XDA App
Yep, Power on with volume down boots into bootloader with a boot flag of 1 and volume up while power on also boots into recovery but with a boot flag of 2. Not sure what the difference is with the boot flag. I know that in both modes with usb pluged in, it is seen by my windows computer as a Viewpad 7e. Which is the same thing that is shown when I have usb debugging turned on with usb pluged in after a normal boot. I looked into the adb thing and I cant get adb to see it, even on my linux box. Kinda wierd the vendor id is 0bb0, Concord Camera Corp.
For now we have to wait for a custom recov and cm7 for our tablets

My viewpad 7e keeps rebooting after rooting - please help
Hi Andyav.... I saw your post that you have downloaded the firmware for viewpad 7e. It may be my best chance to recover my viewpad 7e and have it working again.
My viewpad 7e started a reboot-loop after I rooted it with gingerbreak and ran the google market installation.
I need to restore the original firmware but I can't find it anywhere.
Please send me a link and allow me to download your copy of the firmware for the 7e. I would really appreciate if you could do this for me.
My email address is [email protected]
Hoping you would reply soon...
thanks,
Ariel(Reapjack)
Could you also sned me a link to the firmware. I received one yesterday, but its downloading the firmware at about 5% an hour for some reason! If I used this copy for firmware and put it on a micro sd and update the viewpad from that? Thanks in advance
My email is [email protected]
I pm the link to you for the update.
Reapjack - Not sure how you will install update. I would try to copy file to root of sd card and boot into recovery to see if it will install that way. If not rename it to update.zip to see if the recovery will work that way. Let us know know how it turns out and which way worked. Thanks.
I'm trying to download F70 VSAM_S_W_C_11282011.zip, but I have the same problem, the very slow download...
will you send me the firmware too?.
Thanks !

Update file ran but tablet keeps on rebooting..
Hi Andyav.. Thank you for the update file. The file ran as expected by putting it in the sdcard's root. The update went fine but my tablet still keeps on rebooting.
It seems that this update is overwriting only some files but not all. Maybe that part of the OS that was rooted earlier is not being overwritten. Would you know if there is a full update that will overwrite everyting?
Thank you again.... I appreciate the help so much!
Thanks Andyav !!!
I really appreciate your soon PM with the link.
I have problems with the spanish languaje, hope that this update fixt it.
I'll post the results.
Thanks again !

Reapjack - How did you apply the update. Through the recovery or through a normal boot? I know inside that update there is an updater-script for doing a full update, includes mbr, kernel, system...etc. I am not sure how to trigger it though. Maybe that’s what the boot flag is for in the recovery.
I did finally take the risk and adjust my density in the build.prop file. Tried a few different settings. Default is 180. I am currently running at 160 but did try 200 and 220. Looks good but the display is still not as clear as my phone (HTC Incredible running MIUI). I know the screens are not really comparable, but Viewsonic has been designing and building monitors for years and this is the best screen they could put in this tablet.
Also did some digging around on the internet about the host cable. Found a few here and there but I can be rather impatient at times, so I decided to make my own. Chopped off the end of an old Motorola house charger, shaved off al the plastic around the end, de-soldered the wires and one resistor from the small board. Then dismantled a usb cable I had made for my original Xbox, soldered the cable to the mini usb end, shorted pin 4 to pin 5, plugged her in with a keyboard attached and it worked, first try. I did notice that the host mode is not real reliable. After the initial test I could not get it recognize keyboard again. Checked all solder points, tested from usb female end to mini usb, all tested good. Several reboots with cable plugged in, nothing changed. I knows to go into host mode, I can see it switching when i run dmesg. But it just doesn't know what it attached to cable.
Andyav, i tot the lastest update is 20111125? I dont have the 28.... version for ota update.

After 12 hours of downloading, tried to upgrade from the internal application but after reboot, the process was canceled because it didn't find the .zip file on the sdcard. (error mounting sdcard)
Surely the problem was that the sdcard was not properly formatted.
Now,
the Recovery system shows 1.9 version and bootflag is only "1", regardless of the volume button I use to start (+ or -)
I formated the sdcard and tried to do a manual upgrade with the file downloaded directly from viewsonic: F70 VSAM_S_W_C_11282011.zip, but no luck, the recovery reported bad file.
Any help?
hellodzulz, will you tell me where did you dwonload the 20111125 update to try it

Over the last few days I have been trying to get the ready for custom roms when they become available. Digging around on the internet trying to find as much information as I could about the hardware. While digging around for devices that have custom roms and use the same processor line, I found some rather interesting information about the Galaxy S Unbrickable Mod. Basically it is a hardware mod that causes the phone to enter a Samsung download mode for flashing. Well I took the plunge and opened the case, found and verified the processor, broke out my multi-meter and went probing. Was able to locate the hardware that controls the boot sequence, preformed the mod and plugged it in to my linux box. Ran the Unbrickable Mod Mode Detector and it recognized it. HOLLY CRAP. I have to do a bit more research on utilizing this mod to our benefit but I an rather excited that this mod will work for us.
I've downloaded the file again and everything went ok.
May be the first download file was corrupted due to the slow transfer.
The errors that occurred when selecting Spanish language were resolved.
Anyway, there is an issue with bluetooth.
I can send files to other devices, but I cant receive with the VP7e, when I try to send some file, the VP7e don't show the popup window asking permission to receive file.
Is like it's denied by default.
Does somebody successfully tried to send/receive files with bluetooth ?
Thanks !

[Q] Rooting Venue 7 3740

Hi all,
I recently got a new Dell Venue 7 3740 (yeah, not my first choice, but it was free for buying a computer). Anyway, started reading up on how to root the thing. I have a couple of apps that require root.
I found this thread: http://forum.xda-developers.com/dell-venue/development/guide-how-to-root-android-4-4-4-dell-t2918427
and also the main Dell page: http://opensource.dell.com/releases/Venue_7_3740_Merrifield/developer-edition/
Following Dell's guide to rooting appears to NOT root it. Installing Root Checker confirms I don't have root. Unbricked it and got it back up from 4.4.2 to 4.4.4. By reading the first guide for the 3840, my question is ...
Is the boot image linked there compatible with my 3740?
(yeah, I know this should be in the developer section ... unfortunately I don't have enough posts ... also, I am familiar with rooting/flashing/etc, my first device that I put CM7 on was the original Galaxy S1 ... and I have CM10 on my S3.)
Tried, failed
Yeah I got this tablet with a PC too and tried rooting. It FUBAR'd on me and I had to wrestle with unbricking it. Which sorry to say is a job and a half, the images on Dell's site are corrupt for this WiFi only version (no partition.tbl file, system image incomplete). Ending up downloading the LTE versions firmware to get the missing files and rewriting the batch as the file names for the fastboot commands were wrong too. And even then the tablet wouldn't boot, so I had to store the OTA on an SD card and use recovery to flash it. Unfortunately that leaves me with 4.4.2 and the dreaded clock and browser issues. And OTA doesn't work, it keeps saying no updates are available. Spoke with a Dell rep who said OTAs were suspended and to try again in a week but I think OTA was broken for me when I tried rooting and boot loader was unlocked (which the PDF on Dell's site warns you about).
So now I have a working tablet that skips hours ahead and has general stability issues.

Hmm ... Interestingly enough, I ran through the unbrick procedure from Dell, and didn't have any issues with it whatsoever. I'm not sure if they updated the TGZ since you updated.
I have read that root is for ADB to start with. Can anyone confirm this? If so, then which package could I get for a superuser binary?

I did this process just a couple days ago so everything I pulled from opensource.dell was current. The unbrick tgz on the site shows up as 128mb for the wifi only A1195 and the A5195 shows as 821mb (odd). When I extracted the tgz it said "unexpected end" or something like that on the system image. Then again when I extracted from that extracted tgz.
Following the root process initially worked and the temp cwm recovery let me flash the supersu update. It booted with su just fine and I tried a couple apps that needed root and they worked. Once I rebooted again the tablet showed up with a USB icon and would go no further. Never having dealt with Intel SoC drivers it took me a while to get them installed properly, and then I eventually understood what "full power off" meant lol.
Do you know how I can relock the bootloader and get OTA working again, assuming I'm already on 4.4.2 from the OTA zip installed via recovery?
Thanks.

You better redo the unbrick procces cause as you are now, you won't be able to update your tablet and 4.4.2 has some issues with the clock and browser. The best way to root is by thetered cwm, I did it and it's working great.

This is quite odd. From the documentation, it appears that the A195 is for the LTE version, and the A150 is Wifi only. Since I have the 3740 Wifi only, I only pulled the A150 version.
The Unbricking process was very straightforward and everything went smoothly, and after it rebooted, it prompted that there was a system update from Dell, and that took me from the 4.4.2 from the TGZ, to 4.4.4

I see it now, I think I was misinterpreting the above statement which means I've been flashing the A195 rom this whole time. Thank you all for your help! :good:
After getting my 3740 back to "Unbricked" mode, and OTA upgraded to 4.4.4, it appears that I'm completely locked out of the rooting process.
I've tried to start over with the Dell info (unlocking bootloader), however, neither of my PC's will detect the tablet when using xFSTK (one PC - Win8.1-64bit, other XP-32bit). The tablet IS detected, however, it appears that the drivers are no longer correct(?).
I normally run Ubuntu, and thats where my Android development setup is on ... I see that xFSTK is available for Linux ... has anyone used it? or would I be better trying to fight Windows?

It is mentioned somewhere that the 3740 and the 3840 use the same firmware. Assuming that, what you can do is download the latest SuperUser zip, copy it to the internal or external storage, then use THIS, or THIS to root through CWM.

I'm curious as to what it is you're trying to do. Why do you insist on having a developer's root (just the use of ADB shell), as opposed to full root flashing SuperSu from custom recovery?

I just want full root.
Most of the info that I've read on here and elsewhere are geared to the 3830/3840. Not as much for the 3740. So, by playing with the device and learning what works/doesn't work, possibly others may find this info useful to them.
I've been having issues seeing the device from XP, Win8.1 and Ubuntu, in the 'off' state of the tablet, when the PC should be seeing the merrifield. Just this morning, after bricking it last night, I discovered that my PC seems to see the device right away if I press Vol+ while plugging in the microUSB. (again, something that may help someone else) I was planning on double checking this info later today, to make sure that it wasn't a fluke.
I do appreciate both of the links that you've posted in this thread, and I will check them out. Of course, both are labelled for the Venue 8, not the Venue 7 that I have. Since I've gained knowledge on the unbrick process I feel more comfortable trying them.
I've installed (or tried to install) SuperSU from the Play store, but it didn't appear to help much, since I didn't have the custom recovery setup at that time. I'll work on that tonight.

A quick word on getting the device recognized in off mode, what worked for me was it needs to be completely powered off and nothing showing on the tablet screen then connect and bring up the device manager. Whatever shows up needs to be "Intel SoC" so change the driver to that if needed. When flashing firmware to unlock the bootloader the device's boot screen will show an "Intel Inside" logo instead of the normal "Dell" logo. I ended up running xFSTK commands in advance (they'll wait) and then running over to hook up the tablet (powered off) via USB as for some reason it'll show up and then I hear "da-Dunk" in Windows (device disconnected) after a short while which interrupts the process (same with fastboot commands). This was the unbrick process in a nutshell for me and I'm leaving it now as is (OTA'd to 4.4.4) until hopefully the supposed update to Lollipop comes around and maybe some progress is made on rooting it.
Hope this helps you!

I have finally settled down and got the tablet rooted. What's really odd, was Win8.1 kept losing the proper driver. I'm not sure exactly why ... but suffice it to say, I got it working. It did appear to be more stable when I hit the Vol+ and plugged in the USB, but then again it may have been a coincidence.
Open source dell
If you follow the link to dell open source, they do have a detailed PDF download for unlocking the boot loader etc. The file was too large for me to upload on XDA. I just found it today while I was researching how to root this tablet. I have not had a chance to try it yet.
http://opensource.dell.com/
That doesnt work for 3740 lte. I;ve done everything that was in PDF. OTA image should be with unlocker bootloader and root but its not. ;/
Its adb root not su big difference
Does anyone have any idea to root dell venue 7 3740 lte
The open source is for venue 7 3740 wifi
how can i hard reset this device please tell me.

Flashed Wrong Recovery on Gigaset QV830

So I got a cheap android tablet and I wanted to root it. I was successful so I decided to install TWRP. I searched for my specific model and found an image on a german forum. I downloaded and flashed it and it got stuck in a reboot loop. So I looked at the image and it was for the QV1030. I tried to get it into recovery but couldn't. Many sources told me to hold Vol Up and Lock, and I tried this and more. Nothing would make it enter recovery mode. Then I read about SP Flash Tool and found the stock rom for the tablet and decided I would try to flash that. It kept coming up with an error, and every source online told me to format the flash except for the bootloader and then I could flash it. So I did. Now it doesn't show anything on screen, and SP Flash Tool comes up with error 6045. But it does show up in device manager under com ports as, "MediaTek USB Port" so I think I can still do something about it. I don't have any backups. I don't know what I'm doing. I require assistance please.
So I reflashed the entire backup and it come up with no error. The logo comes up and it plays the chime. The logo does this little shimmer effect and once it gets to this screen, it shimmers indefinitely. If I plug it in, it begins installing a driver and then stops part way through.

I left it for about 5 minutes and it finished the driver. I thought it froze but I was wrong. It shows up now on device manager under Portable Devices as, "MTP USB Device". I tried to see if it was listed as a device by ADB. It is not. Lets just say I've already learned a thing or two about this stuff. Good thing I did it on an 80 dollar chinese tablet and not my HTC One M9

I got it to work again mostly. So I realized that I wasn't flashing the whole backup. Some things didn't have a path and I had to set it manualy. Now it has CFW for some reason, but I reset it and it works now. The only thing is WiFi is not turning on. Any ideas about that?

I actually want to upgrade this from Android 4.2.2 to a more recent version. Do you guys have any ideas about that?
So I've come to the conclusion that while the device is no longer bricked, the current installation is written over the old one and things are conflicting. I know this because I looked through the cache and found filenames referring to apps I had installed before breaking it. So would the solution be to wipe the system partition and reflash the system.img so everything is fresh? Or does the problem lie elsewhere.
I formated the system partition, used SP Flasher to flash system.img and then did a factory reset. The issue has still not been solved. And now that I have done that, I don't have root access anymore. Framaroot says it was successful and I restart and check root explorer on ES File Explorer and it doesn't work.
I gained root access using a different method. However the WiFi still doesn't work. I think it may be that the mac address information was from the backup I flashed from the internet, and therefore doesn't match. I found a guide that tells me how to hex edit a file and put in my real mac address, but it's unavailable under wifi. I don't have the sticker on the back that says it either. How else can I find it?
Turns out the mac address can be anything. I used SN Write tool and an AB DB for my chipset and it still didn't solve the problem. I have no idea what to do. Can anyone help me?
I fixed the issue by grabbing a different backup from some russian website and flashing the system.img and secro.img to it. It now works fine 100%. Thanks

Hey man! I have the same problems with my QV 830. Can you give me the link for system.img and secro.img, please?

From bricked to custom ROM in 2019 (GUIDE)

Here you go:
https://1drv.ms/u/s!AshkuG2cY1T0xPZArSsy6iO1e_UnPw
This is a zip file with all the tools and files you need and instructions on how to use them.
What it covers:
Restoring bricked device (as long as download mode still works)
Unlocking bootloader (firmware dependent)
Rooting (any firmware)
Installing a custom recovery (any firmware)
Installing a custom ROM (any firmware)
I made this because all the guides for this phone were seemingly outdated, and some required tools and files were incredibly hard to find. Didn't want anyone else going through the pain I went through to break this phone open.
Thank you so much for uploading this. The charging port on my Nexus died and I have to use my old Note 2 as a backup, but I forget how this old piece of junk works. This should be very helpful.
I rooted and flashed twrp to boot to a triangle saying system software not authorized. Tried 3 firmwares and wont boot correctly. I got error about firmware update failed use kies... Kies won't do anything and kies 3 says unsupported device. On the 3rd firmware (root66 rooted stock ) firmware file I now am back to the original triangle system software not authorized by Verizon ..
How do I fix this?!?

Did you read my guide? You can't flash TWRP unless you successfully unlocked your bootloader with Casual, otherwise you are limited to SafeStrap. Also you can't restore with Kies, you have to use Odin and the files I've included to restore.

Nice to see people still looking for something like this, so my guide wasn't for nothing!
I was geeked to see this!! but then i got "This item might not exist or is no longer available"
I take it back.. i let it sit on the "failed" page for like 2 min, and randomly it popped up with a download!
Well the auto bootloader didn't work, so now i'm at the root section. However i'm getting an error where ADB isn't detecting my phone. USB debug is on, and i'm definitely in media mode and not installer. The phone shows up in windows and looks good, but adb doesnt detect. I opened command prompt and ran adb /? and found adb devices -l, and it reports "list of devices" and theres nothing in the list. I can't imagine why it's not seeing it. I tried turning on and off debug mode, switching from camera mode to media, changing usb ports. still nothing comes up, but windows sees it fine. grrrr
*edit, well since we can't delete posts i'll leave this here, because i have to. But what i did was re-open the "no you verizon" and it showed DISCONNECTED also. I changed usb ports like 3 times, turned usb debug on and off, changed from installer mode, to camera, to media mode, restarted the phone and the computer multiple times.. and then it just all of a sudden was detected again. So i went with it and it seems to have worked.
-it took 3 times to actually work, you noted it may take multiples, and it sure did. I ran it through the command prompt so i could read the text, and it took 5 times longer and reported much more stuff when it actually worked.
-final edit: if you can't unlock your bootloader, you're still stuck with ditto or alliance from 2014, and lots of apps won't update on android that old. So if you thought this guide was some holy grail, it is not. But still useful if you need the assist, so thanks to the author.
Hi, total noob here, I just bought Verizon note 2 at a yard sale but there is a pin I don't know. When I went to do a factory reset it booted into TWRP, so I am assuming is rooted. Do I need to be able to get into the phone to use your tools? I know nothing about TWRP. I would like to install a newer Android version and unlock it so I can use TMobile. Thanks
Something wrong...
when i try to load this file from the packages folder i get an error message:
"md5 error! Binary is invalid"
none of the other three works for me. they all come back ailed.
any suggestions?
awesome! thanks for posting this, just found my old note 2 and want to get it up and running again for the kids.
Kudos!
Used this to get my Note 2 up and going again temporarily until the Pixel 4a release...
NOTE: I had strange issues with Odin on my modern X570 board (USB 3.2 Gen 2) where I did not receive any errors, yet the process would randomly seem to time out. Sometimes I'd get stuck at flashing boot.img, sometimes it would hang up at the start, once I got to flashing system.img and it seemed to hang....
Used an older PC circa 2013, no issues! Not the first time I've had issues with this newer motherboard and older USB flashing interfaces; had the same issue on my Note 8 (RIP) as well.
excited to try this.
I'm on some rooted 4.4.2 stock-looking rom. Recovery doesn't look custom.
Hoping to be able to install a working Oreo or Pie ROM
great post, bought a couple of these for almost nothing and am having fun playing with them. sadly they are both 4.4.2 but its great fun anyway.

Thank you for sharing. Always difficult to find those tools after a few years!!!

[HELP] New LG phones not booting into recovery or fadtboot[HELP]

Hi
I just got a third LMX210 today to add to my collection. Lol really im just trying to solve a problem. I bought a ulma to replace cm and i came across a ulm model and decided to just replace my cm today. The problem is that all three of these phone which normally have easily unlockable bootloaders will not boot into fastboot. The fortune 2 will not even boot into recovery. They all will boot into a blank screen with the android robot and will boot into download mode.
The natural solution would be to install an older or even plain stock firmware. But say you dont have a windows 10 or Mac computer. I havent found a way to flash lg firmware using a linux distribution yet.
On the other phones i tried removing the laff partition to force the phone into fastboot by plugging into pc while holding the volume up button. This did nothing but repeat the logo until the button released.
Yes usb debugging was enabled and adb was used to try these procedures. The drones at lg know nothing and ask to send the phones in for repair.
Short of re-installing the stock firmware there has to be way to get past this. And to tell you the truth i dont have a way to flash the stock firmware so i dont even know if that will work.
Ok guys got any ideas?
Update.
Ok spent 4 hours on a windows pc today trying to flash firmware and install qcom drivers thinking the download errors were due to the drivers. Then at the last moments went to Tecknights page and downloaded and installed the lgup dual mode program.
So the bastitches of higher android office decided to screw everyone out of bootloader unlocking. The ARB numbers have recently (like in the past 3 months) been changed to 003. Meaning you cannot flash firmware with an ARB number lower than 003.
But that doesnt stop us completely. Two ideas initially popped into my head. Hex edit the .kdz so that the ARB number matches the phone. Or lol split the .kdz into its seperate partition images then wipe the partitions and use qdl or lgup to repair the now bricked phone. No device data no ARB no problem.
Im hoping the former works over the latter but ill keep you informed.
But really guys thats extreme and i cant see too many folks going through the wipe process to enable fastboot. So we have to find an easier way.
Is there any way to know what partition the ARB protection resides in? If those parts could be wiped im thinking it might fool the flashtool into thinking that there isnt any protection.
one of your devices is MTK isn't it? can't you use SP Flash Tool like for other Mediatek devices? you should be able to flash images to emmc_user with locked bootloader, for example boot, recovery, system, ... all you need is a correct scatter file (which you could create with WwR MTK)
So your saying finish porting my recovery and use sp flash tools to install it. See i have been curious about that procedure and how not having an unlocked bootloader would effect flAshing from recovery. I was thinking brick. But its worth a try if it wont brick and i get full Root with magisk. Ty
Btw when i was porting my recovery i ran into a rather large well too large problem. When i went repack using abdroid image studio which i have used in the past with out problem, it would not shrink the image back down even though i was only trading a few files. How do i fix that
start with readback boot / recovery. then try to unpack, so you will know the scatter is right (at least, for this partitions) or compare files with your already existing backup files
no problems here with unpacking/ repacking with AIK
IDEA:::: ok so for the Qcom boards i have a solution possibly. I know that the older software versions have working fastboot and recovery going and can be boot loader unlocked. That tells me that a fota uodate is screwing things up.
PROBLEM:::: ARB my fortune 2 will not let me install at all anything before ARB3.
ARB_location:::: bootloader
Solution:::: download and extract the stock .kdz for device with working features. Wipe parts bootloader and laf using qpst and reinstall. Solves two problems in one go. Allows fastboot and and bootloader unlock and future re-install of stock firmware
may work but remember your bootloader is locked and you need to by-pass this via testpoint (or at least previously enabled oem unlocking and don't lost these setting) otherwise sahara will fail
well it was an idea. I just did some fact checking and also looked at the files dumped from the .dz dump of the fortune 2 stock rom. PBL or primary bootloader cannot be removed or flashed according to a thread it is a pernanent installation.
But upon more reading i can flash my recovery and boot.img using qfil in qpst along witn every thing else. But i need to know wether qfil reads ARB info and if so where i can find it in the firmware so i dont flash that img but instead pull it from phone as is.
i would really like to know what the twitterpating deal is with these LMX210 phones. ok when i firsr got my fortune 2 i bought it for two reasons the rootability of the device and the fact that tje msm8937 board came pre-installed with otg software by default which in my eyes meant no more freaking computer to use adb.
Well it is all there the drivers the software. but guess what. it doesnt work. i have no idea whats stopping it all from working but even lsusb doesnt bring a twitch or hint of reading any thing over the usb.
does any one know how to fix this
Yo. There is definitely ways to flash on linux using virtual machines, wine etc to run windows apps but you got ahold of a windows box to use. IF it is in EDL mode (Qualcomm mode with a driver saying 9008 in it..) then there is still faith you can revive it. You will need the firmware dumped from someone then youll need to run a program creating XML files for the phones firmware parition files. Youll next need a firehose which is what they call the programmers for EDL that send through the commands and firmware in a low low level that these programs like LGUP just do not do yet (don't know why..... Im waiting for someone to program the LGUP dev version with an EDL mode using emmcdl along with a way to create XML files too. Who knows maybe it will happen if we bring it up enough. The hardest problem youll have is getting a proper emmc programmer for the phone. I can source a lot so if teknight doesnt have something to help with EDL just get ahold of me and ill see what I have and send you some stuff.
Man i have been trying to unbrick the LMX-210 CV1 devices since last year. Tek has nothing but supports the work in hope of finding a solution. I have a ton of fire hoses and saharas all of which have cost me nothing but frustration. I have almost every qpst made and have tried them all with my firehose and saharas. Thr only thing i havent done is pull the mbns off my phones and try them. Trust me system dumps are crap.
The only sign of life i came by was flashing an sd card with the gpt and then flashing each partition manually using ubuntu. In return i got the battery logo but thats it.
Would love to figure it out though
By the way I have been compiling kernels. I call it the jokerfish kernel. Its packed full of drivers and debugging features plus gpu idlers boosters and all those crazy fishy thIngs. Its got governors and wire guard. Otg support. Io schedulars and overclocks. Cpu hotplugging and fast charge.
Now i cant figure out how to get fast charge to work but its set up for msm-otg phy-msm-otg qpnp-smbcharger and smb135x.
All that and not a single panic to reboot in over a week and 1/2 which is how long its been compiled. I used tweaks from the dragonheart kernel source and ported them over and did a lil c++ magic.
It has kcal too but n0 app supports it. All kinds of media and sound codecs as well. You think it would be slow but my compiling and coding skills are as mad as me. Hahahaha.'
But dont Take my word for as the gentle over there on your couch. See that smile? Hes as happy as fish in a pond.
Just remember Duhjoker is in no way responsible for bricked devices so try it at the risk to yourself.
This particular fishy thingy works for msm8917 cv1 devices like aristo 2 and k8+ which have been tested by the madman himself.
If you like you could thank me but the permanent smiles on your faces will be just as loved.
lol so fast_charge is working on the kernel but you have to add a custom tunable to a kernel app to get it going. Just add the path
/sys/class/power_supply/usb/uevent
Then you will get a choice of values to manipulate
