So recently i soft bricked my phone and since i don't have money to spend on a new phone i started to search on the web on what the problem was. i found out that all i had to do was flash my phone so i like the trusting idiot and worried fool trusted the multiple videos that i saw in the metro's and t mobiles kdz is the same. i then flashed ms631 i noticed it was wrong when i booted it up an metro appeared, so i decided to search forums and found out that i needed h631 since that is regular t mobile. i found some downloads of different h631 but when i try to flash that on it goes through the first but when it get ready to apply it says contact system admin. i really need to fix this phone i tried normal and cse flash and still get the same results and i don't understand how the download links work that take you to lg's site since nothing pops up. is there a way to remove the stupid mistake i did or do i really need to buy another phone, i cant unlock the phone since metro has a dumb device unlock app that they use instead of obtaining the unlock code. the phone is a t mobile lg g stylo

Is this still an issue or have you found a fix?

Hi Fellow Users!
I just bought LG v10 yesterday with international warranty even though i live in UAE, the problem is i am following all the steps from "step by step guide to root for tmo" but unfortunately i am not able to boot into phone recovery which is odd for me as i am a long time user of android, is that possible my phone doesn't have one? I tried everything adb, manually but nothing worked, i once booted my phone into recovery via adb but i saw green android picture with no command written on it and fastboot didn't worked there so there is that.
1) i tried dirty_cow but stuck at getenforce "permissive didn't appeared which is must needed, i think its related to my bootloader"
2) should i follow LGUP procedure even i am not sure my bootloader is unlocked?
P.S my phone is TMO although its unlocked to use any network.
Please advise, thank you
Unfortunately flashing KDZ file bricked my phone, :crying:
Now its just off it doesn't turn on tried everything any advise?
Update: Went to LG TechServe and handed over my phone to re-flash the original firmware, bad thing they don't cover international warranties as i live in UAE and the model i have is TMO with international warranty so there's that.
Reason to share the story, may people learn from this.
Have you tried with Kingroot app or kingoroot app? These apps can root many devices.
Edit: I wanted to link this to the main Optimus L9 Security Error thread but didn't know how, any mod is welcome to do that for me ^_^
Hello XDA!
I recently acquired a LG Optimus L9 MS769 from my sister to use temporarily until I can get a new phone. Before bringing it to me, she tried swapping SIM cards with my mother's to see if that would work (without doing a reset first), which caused it to boot with that infamous Security Error screen. I have tried following just about every thread that I can understand in search of a solution, however I'm sort of stuck due to my limited knowledge in the all-things-android field. Also, I am aware that this sub-forum is for the P76x models, so sorry if I'm asking for help in the wrong spot.
I started with the most obvious suggestion, which was to try using the LG Mobile Support tool with my phone in S/W mode, with hopes of gaining access to perform a hard reset (hopefully that is the correct terminology). Within the driver selection window on the LG Mobile Support tool, there are three separate drivers for the USA MetroPCS model MS769. I tried running to tool with each of them one at a time, with the same result each time. Sometimes my phone would sit in S/W mode and the tool wouldn't detect a connection, so I would try from the beginning again. When I get it right, the support tool detects my phone, but says first that it is fully up to date with version V10F, then once it fully connects the tool tells me "Only wireless upgrades are supported on this phone." I even tried again using a fresh Mobile Support Tool and drivers straight from LG's support website.
Now, there are plenty of guides out there that explain in the most basic ways imaginable for how to flash stock firmware on my device, but all of them that I have read assume I have access to the device in the first place. There were never any alterations done to the ROM so I presume version V10F was the last OTA update MetroPCS sent the Optimus L9. My goal is to have an accessible device that I can hopefully install my own MetroPCS SIM-card in to, converting it into a working phone. So, I don't really mind if you tell me the only way I'm going to unbrick this thing is by loading CWM or CyanogenMod or w/e. I have no preference over a stock ROM or a custom one. As long as it won't re-lock itself when I insert my old SIM I'm in the clear.
Any help, links, comments, or hand-holding through this process will be greatly appreciated!
Thank you in advance for your time,
Gale
hi!
after reading all related post in this forum and searching google for ages, i am still not able to unlock my z5c's bootloader. it is not a lack of skills or know-how - i have successfully unlocked my z1c and z3c - but this one simply does not unlock.
i have tried both windows and linux, used shell and flashtool, all drivers properly installed, phone is correctly recognized, bootloader unlock is positive, oem unlock and usb-debugging are activated, phone is in fastboot but i still end up with error "command did not succeed". flashtool additionally shows "oem unlock not activated?". it is, but doesn't seem to have any effect.
i also tried to include the .txt file with the unlockcode into flashtools filestructure: flashtool does something but can't finish the unlock proccess and my phone is not resetting.
i even tried those one-click unlocker without success.
and there is something fishy about this phone: three month ago i got it brandnew from a vendor in china via ebay and first thing i did was connecting it to the pc companion to upgrade the firmware which was 5.1 and it told me, firmware was up to date... so i tried the repair option and it told me "that due to it's prototype status it can only be upgraded from certain ips" - although the phone does not show any hints of being a prototype, neither software- nor hardwarewise and even if it was, it wouldn't prevent the bootloader from being unlocked (afaik).
so you guys are my last hope! any further ideas???
regards,
andi
Hmm... Possibly not the solution but have you tried enabling "Unknown Sources" as well?
Another thing is - you can try flashing a later version of the firmware with Flashtool - one that is common. Afaik there are some versions that have trouble unlocking. Try flashing something like Nordic Unbranded, boot it up, make the settings again.
P.S. Flashing does NOT remove the old leftover firmware - it just writes on top. So you should format the partitions (/system, /data, /cache, /dalvik-cache) before flashing in order to start clean.
when i couldn't upgrade the firmware via pc-companion i used flashtool to flash 7.1.1 (some german version) which i kept ever since. so flashing a different firmware before unlocking is something worth trying? i thought of this as well but never actually tried it because i was just too lazy going though all the setup process again if the attempt failed just like the others... but i'll give it a try then!
and thanks for the input!
Hy,
For me i had to make two steps :
- Flash a non-branded firmware from Xperifirm
- Network unlock it (actually for me it unlocked automatically at the end of the warranty ). This step it is critical (as i was informed in the Sony store)
Then the normal cmd command through adb worked fine.
Basically for me the network lock / warranty was the issue that prevented me to unlock the bootloader
thank you very much for your Input! but there is no network lock...
what i was going to do was flashing a different firmware and try again - and there is something else i didn't think of: the usb2 connector of my mainboard is blocked by an infrared device to power up my pc by voice command via alexa and a harmony hub. and to still be able to use the front usb ports of my case i connected them with an adapter cable to a free usb3 socket on the mainboard…
so it might have been the firmware, the usb2 port on a usb3 socket or prototype-status that caused the trouble - but i'll never know cause basically i'll give up on that phone since more issues occured… i contacted the vendor yesterday and it seems i'll get a full refund!
i now got my hands on a shiny new galaxy s7 and hopefully i'll experience the joys of oreo 8.1 and lineage 15.1 anywhere soon without the hazzle!
thanks again for your help and regards,
andi
hello. first of all i don't speak english and i use google translate and i'm sorry for that.
I have an asus-me302kl tablet. I wanted to install twrp but now it's locked. I installed firmware with rawdate but it has no function. I need help unlocking the bootloader. recovery mode does not turn on either. I am wondering if there is a pat file or some other method to unlock the bootloader. Thanks in advance. I hope I was able to explain myself.
please help

This low-end tablet is heavily outdated ( 7 years old ), means you won't find a TWRP suitable to it.

First of all, thanks for the answer. this tablet is a customer tablet. and it's my fault that it's locked. For this I need to unlock the bootloader. is there no tool to flash the software? I managed to install the .rawdata firmware. and the device has root permission but I couldn't go further. Now I'm waiting like this.
@civan34
My suggestion:
Re-flash tablet's Stock ROM ( is a ZIP-file ) to bring tablet back to its initial state ( what includes flashing the Stock Recovery ).
When that's done you can start to unlock tablet's bootloader by means of Fastboot, if it's not denied by OEM/Carrier.
If tablet's bootloader got successfully unlocked you can try to flash LineageOS v15 ( Android 8 Oreo ) onto tablet.

I can't install the stock firmware. Doesn't allow flashing over fastboot. Doesn't allow flashing via recovery mode. Is there a program to install stock firmware?
@civan34
A Stock ROM gets flashed by means of ADB
Example command sequence:
Code:
adb devices
adb reboot sideload
adb sideload <FULL_PATH_TO_STOCK_ROM_ZIP_ON_PC>
adb reboot

I am a little novice at the command line and do not know how to type the command you typed. Should I type as you wrote, or do I need to change the name of the zip on the computer?
my command
(adb sideload stock.zip) and I get read error for this command.Since I don't speak English, I didn't understand exactly how to write the command. I don't want to overwhelm you, sorry for that
I'm in the same boat.
I picked up 4 of these from an auction. I can't unlock any of them, because the Asus tool, (ME302KL_UnlockTool_Instructions) zip file, no longer works. TWRP is available 3.2, link is below. I have rolled back to the stock ROM on 2 of the machines, no joy. Any suggestions or guidance, would be greatly appreciated. Thanks.

I contacted Asus a few times about this Bootloader issue, but today I took a different approach. It appears they Blacklisted the ME302KL from the servers, because it is EOL. I made it clear to them. that I can't access the Asus Cloud or any other Asus tool loaded on the machine and I can't do OTA updates either. I made it clear that I should be able to at a minimum be able to upgrade to 4.4.4 from 4.2.2 after resetting the device. They agreed and are escalating the issue up the food chain.
My hope is they remove it from the blacklist which will fix the "Network Error" message when trying to use the Unlock Tool for the bootloader. I will circle back around, once I hear back from them....

No joy. Asus says they are under contract with AT&T. The ME302KL has been black listed and Asus will not add it back to the unlock tool or provide any support AT ALL!. They keep telling me the unlock tool isn't theirs. But the amount of times Asus's name is used in the EULA, tells me otherwise. I'm waiting to hear back from AT&T on their position on the matter. Stay tuned...
Ok campers, i have a work around for the ME302KL AT&T bootloader issue. I just verified AT&T can unlock the devices, they just verified 3 devices for me. Only catch, you have to have an account with them.
So, If you like people actually being able to hear you on a call, you probably have a different service, like i do. Based on the call, there are really only 2 options. Option 1, Harassment. Someone you know, has them as their provider. A family member, a friend maybe your priest. So, my suggestion is to harass them into they adding the device, under their plan. They only need to do it long enough, for you to get it upgraded. Once AT&T unlocks it, upgrade the OS, add TWRP and create a custom recovery that never goes back to KitKat. then, have them cancel it off their account. At the most, you're looking at $25 for the month, if anything at all.
Option 2 - Go Prepaid for a couple of months. This one is tricky based on the T&C's on their website. You will need to create a new account, $30 for 5 5gb a month. No contract and what you don't use, rolls over to the next month. Make sure to read their T&C's ased on new prepaid accounts with BYOD. I told the agent I wanted to Only use broadband service, no phone for when im working in the field, until i'm still under contract with Verizon. She pitched services, i dodged and evaded. She told me a month to month prepaid plan was doable, to get it unlocked. They would be able to unlock it for free and so i could upgrade the OS. So, it's not too terrible, just annoying to jump through so many hoops. The first option, would be the easiest.
These are just suggestions. I take no responsibility if you brick the device once it's unlocked. It is AT&T and the device may be commiting suicide in lieu of being on their Network. :0)
I sent the message to AT&T with imei of my ME302KL but the answer is been "the manufacturer doesn't have an unlock code for this device".
Help me to unlock my device.
