Hey all,
I recently put the lolipop AOSP rom onto my G Pad, but wanted to revert it back to the stock software.
I plugged it into the computer and tried using the recovery tool, but it did not work, so I put the G Pad into download mode and it gets to a point where it has downloaded the software and is deploying it, but then fails every time.
I tried the offline KDZ method, but when the support tool loads it checks the connected device and always tells me to unplug it and try again.
Does anyone have anything in mind I could try or requires more information to offer a suggestion to me?
Thank you in advance.
I was in the same position a few hours ago. I downloaded the official LG Support tool (drivers and tool available HERE). Launch the LG Support tool, go to Options -> Upgrade Recovery and follow the steps. It should dowload the latest available official formware (V50020D) and flash it to your tablet. I'd recommend a factory reset, since you have CM installed on it. This procedure didn't erase /data (I've done it twice while trying to flash a custom recovery on it). Then you must use LG Flash Tool 2014.zip to flash an older firmware that has a bootloader that allows installing of a custom recovery. After flashing V20B or V20A, you must root it and flash a custom recovery (I'd recommend THIS ONE). It seems a little complicated, but this is the only way to un-brick it (it worked for me).
Get the apk from THIS thread after rooting your tablet (it should flash TWRP 2.8).
I was trying to downgrade my G3 to the original stock firmware (for rooting) following this guide: (androidexplained.com/downgrade-lg-g3/), and my phone became stuck at stage 2 and will not proceed. I've tried every solution I could find to fix the problem, but nothing has worked. For some reason it appears that the phone is not reconnecting to the serial port anymore, so the LG flash tool can't connect. I can't get the phone into download mode to start again, and I can't get the process to resume from where it is at. I was able to re-enable the recovery menu using the JTAG shorting trick, but I can't find any compatible firmware images to flash through ADB. If anyone knows how to fix this, or knows where I can find a ZV4 update zip, then I would greatly appreciate it!

I have the LS990 (Sprint).
When I was stuck in Factory Reset Status 2, I was not able to boot into recovery mode or download mode, but I was able to use this tutorial: (reddit.com/r/LGG3/comments/41wbo3/how_to_unhardbrick_your_lg_g3_jtag/) to renable recovery mode. However, I still cannot access download mode, or else I would use the LG Flash Tool.
I have tried to sideload several roms via adb. Most of them say "E:footer verification failed. E: signature verification failed." All of those were zip files with a single .tot inside. I found one zip that was different (it had a bunch of system images inside). The error I got when trying to sideload that zip was:
"Package expects build fingerprint of lge/g3_spr_us/g3:4.4.2/KVT49L.LS990ZV6/LS990ZV6.1415360315:user/release-keys or lge/g3_spr_us/g3:5.0.1/LRX21Y/150221743942c:user/release-keys; this device has lge/g3_spr_us/g3:4.4.2/KVT49L.LS990ZV4/LS990ZV4.1403169216:
E:Error in /tmp/update.zip
(Status 7)
Installation aborted".
I think this means I found a zip with the right contents inside, but it's the wrong update. If someone knows where to find the correct zip to sideload I believe that would fix the problem. I found this zip here: (twitter.com/utoprime/status/569984569195282432)
Regarding the JTAG exploit I used to get recovery mode back, most tutorials say I should also have download mode back, but I don't. If I were somehow able to get download mode back, then I could use the LG Flash Tool to fix it.
So I had my ze551ml / Z00A rooted, was loving life, all was great. Then I tried getting XPosed access and didn't read up on it prior. Anyways, now my phone is stuck in fastboot, I'm able to flash partitions and all, including recovery partition, yet I cannot enter any mode but the hung ASUS logo, or fastboot. I weas even able to load CM's "upgrade to MM bootloader" package, but still the same thing only with green letters where they once were blue..... Please help, I need my beloved phone back.....
I'm not a pro but if you can access fastboot it is just a soft brick and I'm sure many people can point you on the right thread to recover it.
I've scoured the depths of both XDA and the ASUS forums, and while I've gained much knowledge of how I can possibly fix it, nothing seems to work. I go to select "recovery mode" and it instantly just boots right back in to fastboot.....

Thanks -- you can install giovix`s modder tool from general section
Set it up , use`return to stock option` --in that option , first select boot , then after- recovery(both will be stock)
You then can either
A- Reboot to stock recovery ,adb Sideload stock M -- Follow on to B-( to back-up stock before flashing)
B- Unlock bootloader again , flash twrp and root (if twrp version in modder is now 3.0.3.M4 you can flash lineageos)
---------------------------------------------------------------(if twrp version in modder is still 3.0.2.1 M - you will have to flash 303M4 in fastboot or in 3021M twrp.
1) You might be able to, fastboot flash 3.0.3.M4 immediately and forget above A&B completely
For 303M4 recovery see lineageOS in original android development section OP for download link

So I've yet to try your solution, but I do have an update, I was able to, one by one, flash all the stock files (stock as in the stuff I downloaded from asus site) and was almost able to boot to recovery, but when I got to the red triangle android, I couldn't get it to go further. I've heardf alternate key combos for proceeding from there, and tried them all, but maybe I'm just an idiot...... I'll try the giovix solution when I've got time (patience).
**when I tried flashing the cm upgrade package after that, it went back to square 1, so I gave up for the evening.**

Here's the thing. I'm super stubborn, and I think I know everything (cuz I do....) so of course I decided that I could figure something out, so I tried my way first............ didn't pan out.... anyway, I'm finding any time I flash a TWRP file, I have no access to recovery mode. Regardless if I do it manually through fastboot, or CM upgrade/downgrade or even the giovix fix (yes I tried it). My question is this, Where is there a return to stock option? of the giovix DLs I could find, I see a 'magisk root' 'TWRP' 'bootloader unlocker' and 'Xposed' tools, nothing else.... Am I missing something? or am I just skimming over that part?
I do appreciate all the help, seriously. Even if it seems like I'm not taking suggestions very well. It's moreso I don't have access to a computer most of the day, and it's not a huge priority since I went and bought a zfone 3 max a few days ago (decent phone for what it is....crazy battery life)
https://forum.xda-developers.com/zenfone2/general/tool-ze551mlmodder-t3458145
Functions:
1- Check connection status
2- Bootloader Unlocker
3- Flash TWRP 3.0.2-0 M1
4- Full-auto xposed flasher!
5- Full-auto root flasher!
5B- Full-auto root (Magisk+Phh's) compatible with 184!
6- ADB Shell
7- Return back to stock
8- Erase /system, /data and /cache for a clean upgrade
9 (HIDE)- Auto-reboot to bootloader
10- More functions inside!
well then forgive me for not downloading the correct option. I nowhere see this list among anything I downloaded, so maybe specify which is which ('full' or 'auto')....... I'm already downloading both of them again, because I'm not sure which I already had. But yea, one of the 2 only has the 4 options I mentioned.
Its not rocket science

So i finally see what you've been trying to tell me, and I returned everything back to stock, but I still have the same problem, recovery now loads but system wont boot up. I'll try loading the individual factory IMG files today, via fastboot, or should I use a zip file from Asus via recovery?

In stock recovery - choose update from adb -- adb sideload cmd is >
adb sideload MOFD_SDUPDATE.zip
Put .134 M asus firmware in adb/fastboot folder first rename it to MOFD_SDUPDATE(without zip) before this cmd above and then open up adb and type it in and hit enter.
Just in case you are trying different methods (see if this works )

I'll try it today. Last I checked it was hanging at the ”! Android” screen. But then again I'm not sure I know the combo to get passed that screen, I know it's either power and + or power and - but my only success I got into by button mashing all three keys rapidly, so, yea, I know, I'm am idiot.

EDIT"""" because i got it wrong too , i dont even think about , i just do it
It`s ->
From powered off position
Press Power and Vol +
at two vibes, release power
at boot up screen ,release vol+
in bootloader ,scroll vol up or down to and then select(press power) at recovery selection.
At dead android guy -> press vol + and power for 4 seconds -> release Vol +
You should be in recovery.
i am replying in this post since i have a similar problem, and I am as stubborn as OP. Me posting here is a big step in acknowledging my defeat at last. Hours of digging through the internet didn't solve my problem
I have changed my ifwi and dnx more times than i can remember. (my clean slate is mostly using xFSTK downloader with xFSTK_ZE551ML-sal358-amtech.vn files)
Using the above mentioned method (giovix`s modder tool) to go back to stock i still boot into fastboot, not recovery mode.
trying to unlock bootloader it says on the phone "unlock fail"
Using asus flash tool with raw files i get "gpt command failed"
Using a manual method i get the "gpt command failed" on the "6. fastboot oem partition /tmp/partition.tbl" step
in my opinion as soon as i get some kind of recovery my problems are solved. But have been working four hours on this problem with all possible solutions i could think of, nothing but frustration.
info: current ifwi 0094.0183 (wich should be M)
serial 01234........EF
and using the toolkit on "https://forum.xda-developers.com/zenfone2/general/bl-unlock-ze551ml-toolkit-t3546293" i found out my device firmware version is 198 (wich is probably not good in combo with the ifwi)
little update in a certain config (android 5 / ifwi 0094.177 / stock recovery) i can boot up untill the dead android icon, but with whatever key combo can't get past it... (vol up + power) / (vol down + power)
fastboot flash boot recovery.img (yep i am really desperate to get into recovery) doesn't even give me the dead android.
thank you beforehand!
Last paragraph with android 5 ifwi 0094.0177
Is your serial correct ?
Press vol + once is it correct?, if not you will have to xfstk first again and flash raw (twice) with temp bootloader 0094.1069
See my unbrick video for help
First of all, thank you very much for your reply!
I was not very specific there, the android 5 is not the rom (still wasnt able to flash the rom) its only the files like droidboot, ifwi, dnx, .... that i got form lolipop.
Indeed the serial is still 1234........EF (so not the correct one)
I do understand i have to flash the raw twice to get the correct serial, but flashing raw doesn't work. I get "gpt command failed" every time. (so the point where i have to restart flashtool is not even reached). Also if i try to do it manualy.
I watched your video (thanks it was my first steps into understanding how it all worked) but unfortunatly didn't work for me.
Any other ideas?

Did you get this device in this condition ?
If not, what happened so that you lost serial ?
Anyway , i have never tried this because i have ALWAYS succeeded flashing raw (twice) to correct serial BUT it may work for you.( i am not sure you have a device that can have the serial corrected due to whether its been tampered with previous ) which affects recovery and IMEI.
Usually , xFSTK is used to install temp bootloader - Its supposed to be the lowest level form of unbricking procedure and restores temp bootloader so you can fastboot after-- flashing raw in fastboot via AFT(twice) restores serial -- 1st flash approx 3mins is with incorrect serial and temp bootloader.
After a couple of mins, cmds on phone pauses on RESULT=OK on phone.
You close AFT and open AFT again , input raw and set AFT up -- press Vol+ on phone -> once, serial will be corrected and 2nd flash can be started and left until it boots into android 5 by itself.
If GPT trouble , that link may help.
There is other programmes for starting to create serial and restoring .
Usually people who use these , have to dig deep into buildprop stuff which if tampered with can end up with problem such that you have.
Good luck
see if anything here helps

I've tried to upgrade my M5 E5653, but failed. The device can only be accessed in fastboot mode. I've tried many option, but didn't succeed. I think I messed up the boot image, because I flashed it TWRP recovery instead CWM as proposed in one howto. I got the link to the stock images availabe here, but flashing didn't change anything.

Download Official ROMs for Xiaomi Mi A2 Lite - Xiaomi Firmware
After the success of Xiaomi’s Mi A1 smartphone, it was very much expected that soon or later we’ll get its updated version. We already have a lot of fastboot and full OTA ROM updates available for download from official MIUI website. For your convenience we’ve collected the full list of the...
xiaomifirmware.com
You can download RECOVERY ROM (this is for flashing the rom via recovery)
or you can get FASTBOOT ROM ( this is for flashing the stuff via fastboot mode)
If you go with Recovery ROM then u will just have to download the zip file (latest preffered) to your laptop/pc. Then plug in your phone to your pc with an usb and transfer the zip file to your mobile device. Then go to INSTALL section and navigate to the directory where you transferred the file to and Flash it.
For installing the rom via fastboot first download one of the FASTBOOT ROM from the link i gave you (latest is preffered). After this extract the zip file on your pc. Go to the extracted folder. Now plug ur phone to the pc with usb and go to the fastboot mode (VOL DOWN + POWER BUTTON to go to fastboot. Or if you are on TWRP just go to the Reboot section and reboot the Bootloader/Fastboot from there) .Double click on the flash_all.bat (if on windows) or flash_all.sh (if on linux) it should flash all the stuff you need into it's place. Make sure u are on Fastboot Mode before running the flash_all file.
sorry, i suck at explaining
thank you.
it worked with fastboot and i am back to stock android!
