Can't fix my L90 - LG Optimus L90

Hi,
I recently flashed stock D405n ROM on my phone (http://forum.xda-developers.com/lg-...ck-rom-d405n-stock-rom-flashable-via-t2994824). Since I don't pay attention to details, I didn't see that this ROM will delete my Recovery/Root. I did wipe and format everything before flashing (expect internal storage). The ROM works now, but there's no baseband, so my signal drops very often and I can't get Wi-Fi working... Also, my phone is completely stock now, I can't go into recovery and flash other ROM.
So, I thought that I should just root, unlock bootloader and flash CWM again. Unfortunately, this doesn't work, because I can't get download mode working. I installed all the drivers, repeated that over and over again, tried a different OS, but I just can't get download mode to work. I turn off my phone, (tried taking out the battery too, doesn't work), hold volume up and plug in the usb cable. Phone says that download mode is loading but nothing happens, PC never recognises it and download mode never loads.
Could anybody help me get download mode working, or at least fix baseband, so I can normally use my phone and get WiFi and network working? Thanks.

Phone Bricked

Hello,
I was previously using LG True version 0.6 ROM but wanted to go back to stock.
So I used it via the NVFlash way, half way through it putting it back to Stock, I accidentally unplugged my device thinking it was finished, now my phone won't boot up. Whenever I try to re-flash it with NVFlash the CMD auto shuts off with a message I can't read since it's that quick at shutting off when trying.
I have tried restoring via Smart Flash but that doesn't work (Tried holding vol down & plugging in but doesn't populate anything).
My phone won't boot.
I've tried re-installing the NVidia drivers, same issues.
The NVFlash gets the different stages before failing (Usually it gets to the point where my phone goes into S/W Upgrade mode, then fails)
I cannot get into S/W Upgrade mode to restore via Smart Flash as nothing happens.
Device manager picks up the phone as an NVidia USB Recovery device.
I appreciate any help as I'm lost without my phone.
Step-by-step guides are preferable since I'm new to flashing etc.
The phone is in download mode.
You need to find a way to send the rom to the phone, so the phones downloads the rom again and starts working.
Try pm'ing Paul over Twitter.
This is fixed now.
Unsure why, but trying a different USB port enabled me to use NV Flash and now booted up fine.
Thanks anyway guys and sorry for wasting your time.

Flash gone wrong

Hi,
I've flashed multiple times before without an issue until today.
First, here's my background information:
Samsung Captivate (ATT)
Was running Continuum 5.4.1 but it felt laggy so I attempted to flash MIUI 1.5.13.
Here's what I did:
I wiped my phone using the Odin One click tool, then flashed CM7's kernel and then performed formats of the cache, system, and data, then installed MIUI RC2. After this step the phone should have restarted, then I planned to shut it down and reboot into recovery and flash 1.5.13 onto it.
My problem(s):
-Boot into recovery/download mode using key combinations is not working.
-The ADB console reports device not found when I try to run adb shell.
-The phone is undetected in Droidexplorer.
-When I attempt to download an app to boot to recovery with the phone says there is no space even though nothing has been installed other then MIUI.
What I would like to do:
Get back to stock with download/recovery modes working.
On a side note: MIUI works, but in a very limited way. I can navigate through it, but it won't allow the installation of applications due to there not being room on the phone (as said before).
Thanks!
Update - my phone was being identified as a Nexus S, so without those drivers my phone could not be debugged via USB. I now have the drivers and can perform ADB commands, however rebooting into recovery and into download mode both result in the phone restarting without going to the download or recovery mode.
Try using ODIN and repartitioning. I have good videos on standard ODIN and Heimdall on YouTube just search them. If you can not get out of this contact me, I have been able to partition debrick in the past and it's actually considered by me far more annoying than standard bootloader JTAG in certain situations. Let's hope yours is easier to bail out of!
First of all thanks for the reply and direction.
Secondly:
After working on this all last night I was able to get the phone recognized by Odin and my computer, now I am stuck at one of two screens depending on what I do.
If the phone is powered off then plugged in, the battery charging screen appears but there is no animation and after unplugging it the battery charging image remains.
If I power the phone on it hangs on the Samsung boot screen.
Repartitioning does sound like the proper direction for me to take, but, when I use Odin it freezes while setting up the connection to the phone.
when the phone is powered off try holding both vol keys and plugging in the cable. That could possibly get you to download mode. If not try vol down/pwr at the same time since you are now on GB bootloaders the keys are a bit different. Let me know what happens and good luck
maybe you should try to build a jig and use it to get into the download mode first. or you can buy it on ebay, just search for "micro usb jig".
I've tried every volume and power combination possible to no avail, I can't get into download mode. I've given in and am exchanging my phone. Thanks for the help anyway guys!

HELPPP!!! Accidentally Wiped All data, Stuck on Boot LOGO.

I can't boot into recovery, i have wiped all data through TWRP, and my phone won't get past the lg logo.
What Happened:
I rooted my LG-G4 H811 and installed TWRP too, yesterday, and i thought of trying out a custom rom.
I chose the CM 13 Rom, i downloaded the files.
i put them in the internal memory of the device, (since my phone has an sd card problem, a hardware one) i could've done that using OTG too but i didn't think of it that time.
I go to TWRP using my pc using adb, Because there's no direct method of doing it, not even with the volume buttons. tried them all.
Here's when i messed up
i went to wipe the phone data instead of flashing the rom and gapps first. I ticked all the boxes, and it did clean everything. including the rom files i was about to flash ( genius)
I went back to the main screen and i rebooted my phone and now it's stuck on the LG logo.
I can get into download mode by pressing the volume up button while plugging in a cable
i CANNOT get to TWRP. idk why.
Please help me :crying:
download kdz file with the firmware that you were running before on your phone get yourself into upgrade firmware mode by pressing volume up and connecting USB cable when your phone is turned off and run lgup application to upgrade the firmware and you should be ok unless you experienced bootloop phenomena on you lg4.

HELP!! Le2 x526 Not booting Up, nor Charging

Hello Friends,
Yesterday I was chatting on whatsapp and suddenly my le2 restarts, and then a blue splash screen appears and device keeps on booting,
hence I went to recovery and clear the data, but that also didnt help me,
Then i flash the 13s rom via Flashone 1.9 then also same problem happens, sometimes it went to optimizing apps 3 of 4 and again restarts with blue LED, i were unable to switch it off,
after draining the whole battery I keep mobile to charge but now it is not charging, it only showing Red Solid LED Continuously.
Now I am also Unable to boot into recovery or fastboot mode.
I again flash the stock 13s rom via flashone 1.9 , i got success msg but then also mobile is not booting nor it is charging.
Note: I am on complete stock rom on locked bootloader, never unlocked or rooted, used as come in box.
Please give me a solution on this, I have searched everywhere but not getting any solutions.
Thanks in advance
Try to check your USB cable, most of the time charging issue is due to cable

Cable is ok. I have another Le2 and it is charging with that cable very well
I am facing same problem. How you solve this issue? Blue led blinks after flashing any rom and bootloop.

I also have the exact same problem. Phone started rebooting as soon as it booted up. Somehow i managed to unlock the bootloader, but to no avail. Can't seems to find any rom which can boot up. So practically i have a bricked device with trwp. Formatted the system and other partitions with twrp, flashed many roms. Still the result is same. Bootloops.
Hi,
try to to reimage your phone with QFIL from this site:
https://www.techpoison.in/2017/12/how-to-flash-letv-le-2-x526-stock.html
I downloaded everything from there, QFIL, Sparse image and drivers. My phone was bricked, but its working normally now. After you flash the image your phone should charge normally, just try to boot it up. In my case i had issues with baseband, not detected, no sim function and no wifi and phone was restarting each 3-4 minutes, but it was operable. Basedband issues can be solved by hard reseting the phone and updating it to 21s using the local update, just put the 21s stock renamed to update.zip to internal storage and run system update. When you get the error - APK missing, just boot it up again and retry the local update, should work fine the second time, i just deleted the update.zip and put back again and ran the update.

Flash the 21s bootloader + modem, one ZIP file, should work fine. Not sure what ROM did you install last time. You can give it a shot with with MIUI 10 - its nougat.
I had similar issues, see my topic, maybe it helps a bit.

Brother same thing happened to me, a week ago. I cant say about your problem but my problem was due to faulty power button. Actually due to that reason my phone actually kept restarting itself. It showed red light blinking while charging and wasn't able to bypass the optimizing app screen. I also thought it was a software issue but actually it wasn't. I spent about 2 hours figuring out what the actual problem was. The problem was: As we know when power button is hard pressed for about 10-15 seconds it reboots itself.
Although the repair shop guy didn't put new power button but he added a tiny piece of paper in between the power button and body housing to prevent the issue and voila the problem was solved.

Hi, Thanks. I actually did that first, flashing through qfil the same rom. it helped me to go to settings after umpteen attempts to go past language selection screen, and i was just able to oem unlock and enable usb debugging (actually after a 2nd partial failed flashing). the phone kept freezing within seconds of booting up. Now After i unlocked the bootloader and installing twrp and flashing many roms thru twrp, i am still having the same problem of booting up and freezing at start-up. cant flash again through qfil, as i will again loose the unlocked bootloader and twrp.
At least , now i can try different roms to see which can unbrick it. last one used was the twrp flashable rom based on eui (small eui by aurel) but it also freezes on language selection screen or beyond.
I am running out of ideas, lets see.
2nd partial failed flashing? any issues during the flash process? i had some issues when i used usb 3.0, 2.0 worked fine for me. If you have also charging issues stay in twrp and let the phone charge properly, its slower but should work fine. You can try to flash the 21s bootloader with modem, maybe it will boot properly. But try it only when you are able to enter the fastboot mode, longpress volume down and power for 10-15 seconds, if that is working you should be able to flash twrp via fastboot and you can experiment a bit. Try to find the chinesse twrp 3.0.2.0 and try to flash the stock 21s version. Should be also an image file, in standard twrp go to install - image, after selecting the image file click on recovery and install, after installation go back, reboot, recovery. Copy 21s to storage, wipe data, cache, dalvik and flash it, chinesse twrp will skip version check and will let you install the stock image, after install reboot but click on do not replace recovery button - this will keep the chinesse twrp installed.
If nothing helps it can be only a HW failure, maybe the power button, try usb 2.0 port during the flash process, i had issues with 3.0 on my pc, if that doesnt help.try a different cable, no more suggestions, sorry.

My phone has been flashed multiple times by qfil method. And always it hangs at initial setup (so it boots up, but hangs at language selection or further up screens, before setup can complete and launcher could be loaded).
While trying to flash again with qfil once it stopped at 25 percent (because the battery went dead). Charged the battery and booted up the phone, and i was surprised it booted up. After 2-3 attempts i was able to reach the launcher screen and immediately enabled developer options and oem unlock / usb debugging. Only had few split seconds to do this and the phone froze again. After that i installed twrp and hence treying different roms. Most fail at setup.
Just tried MIUI 9PRO ROM. It also froze at setup multiple times, but once i was able to complete the setup and miui launcher is up , but it reboots or turn off the phone just after that. So cant do anything with the phone. Unsure of whether a newer bootloader will help in these freezing issues as i have been able to boot up at least in some roms only if for few seconds. Will try to tinker the settings of miui rom (if the phone let me do it before freezing/hanging). Lets see. Thanks for suggestions. More suggestions welcome, because i am still unsure weather this is a software or hardware related problem. I am guessing that it may have something to do with Google security as earlier i was getting msg that phone has been wrongly resetted and needs to verify with Google (but i couldn't get a chance to use the same account, as phone kept freezing at setup).
Did you fully charge the battery, if not let it fully charge in twrp. Flashing the roms in twrp works everytime or do you see any errors? Before you flash anything disconnect the usb cable.

Try to flash the 21s bootloarder with modem, one zip using twrp. Go to fastboot mode and wipe modems. fastboot erase modem1st fastboot erase modem2st. Put the phone to flash mode and reimage with qfil. Before you do it write down both imeis, you can find them also on the original package on the backside. Also try to remove all sim cards from the phone and try a different cable. If nothing helps, hw issue, maybe the power button mention earlier in this thread.
After reflash skip everything at setup and reset phone to factory defaults. OEM is already unlocked, you dont have to do it again.
I have charged the phone fully before any flashing after that error. I can flash the phone through twrp without any error msg. The phone boots up most of times in various roms but hangs at or after the initial setup screens show (like language selection etc). Flashed the modem+bootloader, success, but it showed bootloader version as 20s (not 21s). Tried the commands u mentioned to erase modems, it say error failed, no such partition found. I had checked the partitions with parted and 56 partitions are there including the modemst1 & 2.
Now re flashed via qfil , did as advised but again the same problem of hanging / freezing at or after initialization screens of various roms.

Yeah sorry i screwed the command its fastboot erase modest1 modemst2, my bad.
Just now i was able to complete the initialization (setup screen) of sparse image india rom. I can reach the launcher and settings for few seconds before the device freezes or reboots.
So the same problem , with which i started, the only good thing is that i have been able to set oem unlock to on, so that i can flash trwp and various roms (but all fail with the same freezing issues)

So you erased modems and reflashed with qfil right? If so i assume its a HW problem. Try the fix with the power button, i ran out of ideas
Last thing which can help maybe: https://www.youtube.com/watch?v=LH3VOIlLfvo&t=135s
Download 21s stock image + the chinesse twrp, links should be under the video, i think so, or look somewhere in the forum for new links. Try to reflash the 21s, some people reported that freezing issues were gone after installing the latest EUI. Basically you can do the same after QFIL reflash but you need enough time to copy the ZIP file as UPDATE.ZIP to the internal storage and run the local update via setting, system update and local update, i hope that TWRP will work for you, just follow the video tutorial.

Did that also, the same problem. The phone freezes after the os is booted. I was wondering what is that isnt touched by flashing ( in download mode or fastboot mode or through twrp). I may need to tinker that. The roms are all fine in the sense they all stop at the same points. Something in the phones partition, which isnt touched by flashing? (There must be, as i flashed with qfil, the oem unlock remains, the bootloader didn't lock, and it remains unaffected by re-imaging)
Try this, maybe it helps:

EMERGANCY Issue with flashing a new ROM

Hallo, yesterday my phone kinda got laggy so i thought to my self hmm why not flash a new firmware. Aftewards i said to my self, why not go even further and flash lingeageos 16 and thats when it starts going down. The phone would crash or black screen (volume and power key still work and show their UI on the screen) while the rest of the screen was black. I panicked and quickly wiped everything system,internal storage and all that via TWRP recovery. Now i face a even bigger problem. I cant flash anything onto my phone. The Flashtool requires some drives which i installed as the program instructed but with no great result. I put the device in flash mode by holding volume up key and putting the usb cable into the phone and still nothing i can do. I tried various tools to convert the FTF firmware into zip so i can flash it with TWRP that luckily still works. If i try to flash anything i get the error: 7 or bootloop/stock on loading screen. What should i do?
UPDATE: I flashed a stock rom via newflasher, so for anyone in situation like me, where they phone is a very essential part of they everyday life and everyday responsibilties. Then i recoomend this guid for you, it says everything you need to know when you are in a situation where nothing works: https://www.xperiablog.net/2018/01/...-firmware-for-xperia-xz-premium-xz1-and-more/
