Hello,
First off, I've gone through the forums and I have looked up other posts and despite everything I cannot figure out how to get my nexus 7 tablet to be recognized by the computer (I tried and after two days of searching for answers I decided to make a post). I like to include this information so people don't assume that I post without browsing or haven't tried anything yet.
The thing that I am having troubles with is that I have a nexus 7 tablet that is softbricked, I have already gone through a lot of ways to fix that problem (I found the best solution is this:http://forum.xda-developers.com/showthread.php?t=1809195). However, the issue is is that I cannot get my computer to recognize the nexus tablet to flash it and restore it back to factory settings.
I have installed and updated the device drivers on my computer, but still I have had no such luck. I found that ADB doesn't recognize the device whilst in the Bootloader, but still will not recognize the device in recovery mode. If anyone has any tips, or suggestions that might work PLEASE let me know, at this point I'm getting desperate and any/all help would be greatly appreciated!
Thank you!

adb is not designed to be usable in bootloader mode. You need fastboot for that. If you have the fastboot.exe program in the same folder as your adb stuff, try this:
fastboot devices
If it reads, then all you need to do is fastboot flash the various .img files back to the tablet. There are tool kits that do this for you, but I prefer doing it manually as there are less chances of things messing up and if they do, you're more likely to know at what step which could be useful for further troubleshooting if need be. It is important to download the correct img files due to differences between the generations and wifi / data enabled ones. There is a flash-all script that you can find in the download of the factory images, which might make it easier, but you can just manually flash the separate files as sometimes you don't need to bother with them all (like the bootloader) though if the script works, then it'll be fine and might make it easier if you are not familiar with the commands.
If you don't have fastboot at all, just grab it from here: http://forum.xda-developers.com/showthread.php?t=2317790

You won't get adb in bootloader mode.
You have to use the fastboot command.
Please tell the OS on your computer.
Use the tool in my signature as an environment.
Download 7zip, and install that.
Then go here and download the proper image for your device.
It would either be "Factory Images "nakasi" for Nexus 7 (Wi-Fi)" or "Factory Images "nakasig" for Nexus 7 (Mobile)".
Grab the 4.4.2 version.
Extract the downloaded file with 7zip into the "Work" folder in the tool form my signature.
Then extract that "nakasig-kot49h-factory-83d93b5f.tar" file with 7zip.
Then go into the folder that came out of that, and extract the "image-nakasig-kot49h.zip" into the Work folder.
And enter the following commands while in bootloader.
Code:
fastboot oem unlock
fastboot erase userdata
fastboot erase system
fastboot erase recovery
fastboot erase cache
cd nakasig-kot49h
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot reboot
Make SURE you grab the correct image for your device. Wifi or Mobile.
I also assume that you know the .img files should be in the Work folder before you type thse commands into my tool.
Hey guys, first of all thank you for the speedy replies and steps I should follow.
Right now I'm using OSX but for the tablet I'm using a virtual Win7 machine to try and get this damn tablet to be recognized by the computer. The process is being delayed a little bit because my micro USB cords are being temperamental, meaning that the tablet has no juice, and when I mess with it (using the power + volume buttons to boot to bootloader/recover) the cord comes unplugged. I know automatically you guys are going to pinpoint this as the source of the issue (mainly because I would too), but it works fine if just laid flat and stays connected. It just has zero charge so when it disconnects/reconnects I literally have to power it back up, just need to wait for it to have some charge before I tinker with it more.
I will post updates after it charges.
Although I already thanked you guys, thanks again for speedy reply. It's much appreciated.

I suggest to STOP!!!
If you are trying to restore the device and the cable disconnects in the middle of it, it might not be recoverable. That would be one of the few ways to really damage the tablet as they are pretty difficult to hard brick. Don't half ass it with stuff like this. A good cable is not THAT much and will certainly be cheaper than a new tablet or getting it to a point where you might have to send it somewhere for service.
I'm not familiar with Macs, but if you are more so, then this might be better than using a Virtual set up:

It's actually working fine now (in the sense that the computer can now read it). The Virtual Machine also works just as good, but for some reason the toolkit I'm using won't properly return the tablet to the stock image using the SkipSoft Android ToolKit, so I'm going to have to try and find another way.
Thanks for your guys' help.
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.

Hmmm ... I took this to mean that I could use the same boot.img as the Venue 8, and tried the process from this thread: http://forum.xda-developers.com/dell-venue/development/guide-how-to-root-android-4-4-4-dell-t2918427
NOPE. (Don't try, it'll cause the tablet to go into the "help my androids' fallen and can't get up" icon. )

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

I'll try to get as straight tot he point as possible.
Been using my Mobile one touch pix 7 for a little over a year and always installed Ota updates. Well I rooted the tablet not too long ago, forgot which method I used, but was working fine.
an Ota update came through and totally forgot it was rooted, and tried to install it, at which point the whole tablet got bricked.
It ended up in recovery, and I selected due to failure, to format and wipe the data.
Anyhow, The unit will stay at the boot screen for a while then show command error and then show the recovery screen, my only options are:
reboot
update from sd card
update via adb
update via memory
reboot Bootloader
power off
Well I've tried updating by downloading system images via adb, they return a verification error.
I've tried using adb side load to try to install an Ota update file I found for it, returns a verification error.
I cannot get into download mode, fast boot mode I think does not work as windows reports 3 android devices, but the mobile update software cannot see anything, and fast boot gets stuck at waiting for devices.
I suspect the tablet is for lack of a better description totally bricked and just a paperweight.
I am at a loss of what to try from this point. I'm sure wiping the data after the failed update killed it completely but not sure.
Anyone have any guidance here? I've downloaded a few images from the web I found that say they are for this tablet model, but still getting verification error.
Is there any flashing software I can get that may be able to access the tablet or can I copy a file to the scared and have it try to run an update from there. I don't care if it is rooted or not, just want to get it usable again.
I can run Mac OS, windows 10, windows 7, windows xp, or even have no issue getting a linux version going, whatever will work best for this I can use it. windows 10 I was able to manually add the drivers but windows 7 is not letting me do it the same way. I can connect via adb sideload only, no other adb functions seem to work.
I'm not a total news when it comes to custom rooms, as I have done it with another tablet, and an android car radio, but those were pretty straight forward and bootable so never ran into a brick issue yet.
I have a feeling this is toast and I hope that is not the case.
If anyone here can help out, I would appreciate it.
Thanks again....
Need help here to. Been searching with no luck. Any my issue is.
Rooted kingroot, flashed twrp with flashify and now I'm stuck on twrp. Been searching for any custom stock rom. I forgot to unlock the bootloader but I did enable usb debugging (i didn't see any oem options).
Any k 28532Jonsunf of help would be greatly appreciated.
This sorta happen to me. I rooted pixi 7 with kingroot, and was able to delete a lot of bloatware. However, when I was using lucky patcher it pretty much messed up the play store. But it was fine. I could download stuff through the Internet. But sooner or later I needed to fix it. Tryed a lot of ways but it didn't help. So I factory reset the tabletand now im stuck at the Setup Wizard. It just won't let me let me through. I thought its was over, but then I get a message saying there is an update available. So I download it and installed it. But all I get at the end is error. So now I need to flash it with stock. I tried the img. too, but it doesnt show up in the recover menu. If you found a solution please tell me
Can anyoonneee help me find a good Custom Rom for the alcatel one touch pixi 7 (9006W)? Sucks that there's not much info for this device (probably cause the device sucks lol) I'm running on lollipop 5.0.2 and am not able to get OTA update due to rooting. Unrooting didn't help. It seems only answer is custom rom but don't want to risk bricking it as I don't have a computer at home. Also, I am new to this so if anyone can share some insight, I'd be eternally grateful
P.s
It's a t mobile device but I only use it on wifi.
Am using kingroot.
Have never installed a custom rom
****ing device is 8 gigs. 1 gig Ram.
Is it possible to get Nougat?
Help meeee lol

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.

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.

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.

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!!!
I have a LG K7 that will boot to system, but no matter how many times I try, it wont boot into either download mode or recovery mode. I've tried the combos of vol down + power and vol up + power and every other combination I can think of. Pulled the battery and it didn't improve.
Anybody ever see something like this? Any suggestions on how to get it to work?

Tried ADB commands?
adb reboot recovery
adb reboot bootloader

Yes, and adb devices shows nothing. I'm wondering if the bootloader is locked and maybe that's why I'm having problems.
Also, I'm having problems getting TWRP to load. Do you know what version of TWRP will work with K7?
Do you have to root first before installing TWRP from the playstore?

If "adb devices" shows nothing imo it's not recognised so not possible to flash.
Tried other cable/port?

Never did that.
Always flashed directly but I guess so.

@BigZ1 sorry, none.
OK, finally can get into firmware mode and also recovery mode. Reason I needed this is to be able to try loading custom roms on this old phone. Now I'm on to the next pothole in the road.
I would like to install twrp. twrp from the playstore wont install unless you are rooted. I am using stock rom android 5 unrooted. I've looked at all the options and from what I see, I have the classic chicken and the egg dilema. Can't flash until my OS is rooted, and cant root without flashing.
The only way out is to use adb to flash the twrp file. Unfortunately I can't get adb devices command to acknowledge any devices. I have usb debugging on, and by connecting to a windows computer, I can view internal storage. So the device is communicating, but not via adb commands.
I tried to use the LGUP tool from LG, but it wont let me select my device, It sees the correct model of phone on Com3, but wont let me select the model. I think it's because LG has turned off their servers and cast us adrift.
If anybody has any ideas, it would be much appreciated.
I think my best bet is to get adb devices to work, or find a way to root my OS. I just cant figure out how to make that work. Help, please!!!!
BTW, in the stock recovry mode, LG has removed everything useful (e.g. install zip, reboot options, wipe cache, etc.) so the only option there is factory data reset. Thanks a lot LG!!!!!

Sorry to tell you but afaik this won't work.
fastboot flash recovery <filename.img> would be the command but this will only work if it's unlocked.

I doubt that fastboot will work if adb isn't but it's worth a try.
You are right, a fastboot command would do it. Only reason I mentioned adb devices, is that if adb can't see the devices, fastboot wont either. I'll try it again, but so far no luck.
What I don't understand is why usb debugging lets me look at the internal files, but adb devices doesn't work. Perhaps you are right, the bootloader may be locked. Only thing I could find about that is in developer options I turned on OEM unlock.
Is there any other way to unlock the bootloader?
Sure wish I could get some of the LG tools working. They might enable flashing of twrp recovery or one of the various zip files that would root my OS.
Any more ideas? I'm desperate enough to try most anything....
One more question. When you try to execute adb or fastboot commands, should you be in what LG calls "firmware download" mode? Seems to me that when I did adb or fastboot commands on other vendors phones, I was able to do so while the OS was running.
Grasping for straws....
Well, it looks like you are right. There is a fastboot command
fastboot oem unlock
that would unlock the bootloader. Unfortunately while it's locked, I can't get fastboot to recognize any devices, so I can't unlock it.
Is there any way around this?

Fastboot is afaik only working in download/bootloader mode.
ADB working on any other.
So <adb reboot bootloader > usually gets you there (but adb doesn't work) or switch to it manually.
Idk if you need to flash an unlock.bin by LG.
Got it before 31.12.21 for my G5.

Yeah, I just discovered that LG discontinued support on Dec 31, 2021. So, looks like I'm out of luck for getting anything from them.
My only hope is that someone has that lockbin file and would share it. Sure wish LG hadn't left me high and dry.
Now that LG support is gone, is there any forum that might have some kind of workaround for the bootloader?
anybody got a lockbin file for K7????

Oh yeah, one more thing. The phone is still of some use to me, if I can find a way to root it. So far all the stuff I tried (kingoroot, supersu, magisk) have failed.
Anybody got any suggestions???

The file got generated by LG after I entered a long code on their developers site which is afaik different for each device.
So someone elses unlock.bin might even harm your device.
You may be right, but at this point I don't have much to lose.
One thing I would like to do with the K7, is get it rooted. I can move files to the internal storage with usb debugging. I can't install any zip files and that makes it really difficult to find anything that can root it. Thanks again to LG for reducing the recovery menu to "factory reset data" so the phone has almost nothing useful.
If you can figure out a way that I can install zip files, please let me know.
I can't find anything that will let me flash the device without root, and I can;t get to root without some tools in the recovery menu.
Thanks
OK, I have not found a way to root. So I thought I'd take one last look at flashing/upating the firmware. I found a .kdz and a .tot file that I'd like to try. At this point I'm not risking much because the phone isn't worth much to me as is.
So, if you had a .kdz and .tot file to try out, what app would you use to flash it to the K7?
I tried to get LGUP to work and LG flash tool, but cant seem to make them work. If I knew what one to use, it would narrow my search. I'm trying to flash the K7 firmware by running exe files (LG UP, LG flash tool) on Windows 10.
What do you guys use?

So, I managed to find a patched version of LG flash tool (2.0.1.6) on this website (thanks to member ieatacid), that doesn't give me errors immediately after I open it. The first thing I notice is that it doesn't appear to recognize the K7. If I try checking the box for manual mode and adding the file I want to flash, the click start, it tells me to "select model dll file". This is probably a result of flash tool not recognizing the phone. Anyway, where am I supposed to find this .dll file? I've searched everywhere and came up empty handed.
Can anybody give me some enlightenment on what I am doing wrong? Any help at all will be much appreciated.
Is there a tutorial on use of the flash tool? I looked but haven't found it yet. Just some youtube videos that are terse and lacking in detail.
Thanks!

I don't know why I didn't think of this earlier. I own 3 LG phones (LGMS300m1, LM-X210ULMG10r. VS500PP9). I tried all 3 with LGUP tool. The tool recognized 2 of the 3, and failed to ID the LGMS300 (K7). Anybody got any ideas why the tool would recognize some but not others?
I am the only owner of the two phones that LGUP would ID. I guarantee that the bootloader on them was never touched (unlocked or locked, in any way). So that's not the answer.
It would be a big improvement for me, if I could at least get the LGUP tool to work for the K7.
BTW, I tried all 3 phones on the 2016 version of LG Flash Tool. All 3 failed to be identified.
Please, if anybody has a hypothesis for the odd behavior of the LGUP tool, I would love to hear it. Any suggestions are welcome.

Update on the never ending saga!
I found (on this website) an LGUP tool (version) that is for the MS330. So it works (albeit not so consistently). I was able to flash a .kdz file after several trials. Apparently when LGUP connects, it puts the MS330 in bootloader mode, waits 15 seconds for the device to respond and then begins flashing.
Now, here's the problem. I have a .tot file I'd like to flash. When trying to flash a .tot file, 15 seconds is not enough time for the device to respond, and I get an error for what appears to be an asynch error. That is to say, the MS330 took a second or two more that the 15 seconds to respond saying, yes i'm in bootloader mode.
Is there any way to give it a bit more time? Surely the members who use LGUP tool would have encountered this behavior, and would have found a solution.
Words of wisdom, anyone?
