Help me unbrick my LG D620r - Android Q&A, Help & Troubleshooting

Hello folks
Here's what I've done and what happened:
1) I've been using LineageOS 14.1 with no problems, flashed it with TWRP 3.1.0.0
2) There was a system update available, but didn't go well and was stuck on splash screen
3) I flashed my original 14.1 ROM again with no problems and phone was OK again
4) I found out that there's 15.1 Lineage ROM available. Couldn't flash it with with my TWRP 3.1.0.0
5) Had to reflash recovery to newer version (3.2). It was provided along with the 15.1 Lineage ROM, downloaded from official website
6) Flashed recovery with no problems with Flashify, but trying to flash 15.1 gave me an error
7) So I tried to flash the good old 14.1, but couldn't do it with the newer TWRP
8) Flashed the good old TWRP 3.1.0.0 from the TWRP 3.2, it went OK, than flashed good old 14.1 ROM
9) Phone is still freezed on splash screen
So the result is, what worked yesterday with no problems, today doesn't work.
Any suggestions?

Seriously noone has any idea what to do?...

One plus X - Working CM13-2016/10/15 - TWRP 2.8.7.0 Stuck - Recovery not working

Hello!
This is my first post. I've searched for hours. Visited over 200 sites and forums tried multiple things installed all available android tools you can find online and i am seriously stuck.
Setup before problem : One Plus X - Cm13 - Version 2016 - Oct - 10. This is updated from the cyanogen website and its treated as the stable version.
Downloaded the latest version which is the 15th and got stuck at bootloop. After some searching i discovered that i had to updated my bootloader as it was the same since November 2015. In the website that i got the new version i was also given the new TWRP version 3.0.2 . So i went into my recovery flashed the new bootloader , then the TWRP , then the new ROM. Mobile boots up shows completly empty fresh install CM 13 without gapps or any of my previously installed programs. Everything is still in the storage. All installation folders from the various programms i had.
My recovery mode refuses to Boot. It just stays on the one plus logo. Tried TWRP manager from the OS but the old version 2.8.7.0 refuses to be unistalled. Adb command lines : I've been trying on windows 10 , 8 , 7 with the appropriate drivers and the only thing that i can make the phone do is go to either FASTBOOT or normal boot. Flashed the TWRP multiple times and no changes what so ever. I can make the mobile show up with ADB device, Fastboot device it shows success and when i try to boot into recovery it just gets stuck. I also got the MTP package from Windows. Basically i bricked my phone within a glass. OS works but Recovery not. Fastboot is supposignly working but i see no changes.
Thank you in advance!
Install original stock recovery then 2.2.3. If you want to use ashwins cm13,cm14 from here on out and a couple other ROMs required updated bootloader. You achieve this by flashing 3.1.3 Oxygen OS. After you updated your bootloader only twrp you can use is blusparks latest v41 or Nichets twrp. On a side note 2.8.7 twrp is old 3.0.2 is latest.

Hi guys if anyone facing same problem Read this
PROBLEM
1)Error Code 7 while flashing new ROM (like Nogut ROMS ).
2)Remote dtb not found while updating old twrp to new (eg. twrp 2.8 to twrp 3.1.0.0)
Cause of problem
Users who have already flashed and rooted their phone and using custom ROMs like CM12 CM 13 or any other from past year will likely to face this problem
while updating twrp recovery or while updating to new custom ROM Nogut cm14 .
Because new custom ROMs have bootloader in diffrent partition (something like this) so you wont be able to flash your phone with new ROMs i.e cm14 or nogut or you wont be able to flash new twrp recovery which is 3.1.0.0
Please keep in mind if you are using following twrp version then you should flash your phone with old twrp 2.8.7.0
twrp-3.0.2-0-onyx.img 14.4M 2016-04-04 23:04:23 EDT
twrp-3.0.1-0-onyx.img 14.5M 2016-04-01 04:24:54 EDT
twrp-3.0.0-1-onyx.img 14.5M 2016-02-15 23:17:25 EST
twrp-3.0.0-0-onyx.img 14.4M 2016-02-06 09:18:41 EST
above point is important look at the solution now
Solution
Step
1)flash your phone with old twrp version TWRP 2.8.7.0 using fastboot method(because we are going to install stock recovery in my case stock recovery of oneplus X lollipop version)
2)after installing stock recovery install 2.14 ver of stock ROM of oneplus X (for oneplus x devices) (for other brands eg samsung look for ur old stock recov and ROM)
3)install old Stock ROM in ur device
4)now again boot into stock recovery and install latest stock ROM (for oneplus X i installed latest oneplus X oxygen OS 3.1.4).
5)after doing above step you can install latest twrp-3.1.0-0-onyx.img without any "remote dte not found error" using fastboot.
6)once you flash twrp-3.1.0-0-onyx.img flash your phone with latest CM14 or any latest android N or nogut ROM without any problem
Note : For error code 7 some people suggested to edit udatescrip file which is not good solution and it is temporary and it wont work for all so do it as i suggested
Comman ERRORS :
1) if you are on twrp 3.x.x.x you will face Remote dte not found while booting your phone in stock recovery using fastboot
so first of all flash your phone with old twrp 2.8.7.0.
2)Do not wipe your internal storage in frustration it will create more problems because you wont be able to transfer files into your phone to flash it (Use OTG cable or SD card if u did it already).P.S you can do it afterwards
Do i need to install stock recovery of stock ROM ? some help would really be appreciated
i can install all twrp upto "twrp3020 " version
but if i try to flash greater version like twrp3021 or twrp3100 m getting same error
i need new twrp because i am not able to flash Android N custome roms i am getting an error code 7 when i am installing ROM
Follow the mega unbrick guide, then update your bootloader then flash latest twrp.

are you on stock recovery right now ?
Finaly the Lv.2 support got it back working via "our" msm unbrick tool (Still got it on my drive =D)
but learned nothing - trying to get lineageOS again.
The recovery is now TWRP v3.1.0-0 for E1003_15_161107 (it works for now on a backup..)
But... i must say - I'm very worried that i cant flash lineage again..
I dont know what the trick is...

Yes!!
I ve been looking for a solution the past days since i got stuck in older twrp versions and could only upgrade to android 6.
Thanks man!! You rock!!

Not possible to install an android version above 6.

Until today, I had been running Cyanogenmod for Android 6. I decided to install Lineage OS with Android 7 and downloaded the latest version. I did a dirty flash but a bootloop happened after installation. So I followed this tutorial.
https://forum.xda-developers.com/redmi-note-3/how-to/unlock-bootloader-twrp-root-7-2-3-t3359492
I did everything from the beginning to have a fresh start. After I had TWRP installed, I installed magisk, then Lineage OS, then gapps -> bootloop.
Then everything again. TWRP -> Lineage OS -> gapps ->bootloop
Then everything again TWRP -> Lineage OS-> bootloop
Then I tried latest Nitrogen OS. Everything the same order as above -> bootloop.
Then even with the latest official MIUI -> bootloop
Then I tried the stock rom Miui 7.25 from the tutorial link above. And that one worked. So I cannot install a rom with Android 7.
Any suggestions?
Thanks in advance.
Bootloader must be unlocked officially or flash latest MIUI global beta & unlock unofficially

It all works now for some reason. However, now my phone doesn't recognize the whole internal storage. The problem appeared after I had flashed a fastboot MIUI rom and TWRP again. When I entered recovery mode, TWRP showed that there are only 10gb of storage total, even though there should be 25 gb. It is as if the space is not formatted or something.
Anyone got a clue?

Downgrading LineageOS

Hello,
It could be just me, but I feel like the 20170829 release of LineageOS was running better on my device than the 20171010 version I'm running right now. I tried to downgrade to that version, but I couldn't get it to boot. I did the following:
1. Backup on TWRP
2. Flashed vendor image and bootloader from the N9F27H release (obtained here) via fastboot
3. Flashed the 20170829 release of LineageOS via TWRP
4. Flashed FED Patcher
5. Reboot
After that I couldn't get past the the boot animation. Am I doing something wrong? Thank you very much in advance.

TWRP or OS But Not Both

Hi, I'm hoping someone can offer some assistance. I have an Elephone P9000 (normal version NOT lite) that has official Android 7.0 and I want to install LineageOS 14.1.
As per the instructions I used SP Flash Tool to downgrade the phone to Android 6 (Elephone_P9000_20170112) which worked fine.
I then attempted to install TWRP 3.2.1.0 which also appeared to work ok as I could boot into TWRP recovery and all looked good. However when I tried booting the phone normally it stuck at the white boot logo and would not progress any further.
So I reloaded the Elephone_P9000_20170112 rom again with SP Flash Tool after which the phone would boot normally and then tried installing TWRP 3.0.2.8 as I'd seen threads saying that this version definitely worked with the P9000. However this produced the same result that I could boot into TWRP fine but it would get stuck at the boot logo if I tried booting the phone normally.
I have also tried re-installing the ROM but unticking the recovery option in SP Flash Tool hoping that this would leave the working TWRP intact but this didn't work either.
When I try to boot into recovery I get the little Android laying down with a red exclamation mark.
So I don't know where to go now. I can get EITHER Android to boot or TWRP to boot but not both.
Just in case it is relevant, I am using SP Flash Tool v5.1804_Win in Windows 7 32bit. I don't have any SIM's in the phone and no SD card inserted.
Can someone point me in the right direction please.
Thanks
Russell

Thanks very much, that worked fine and AOKP looks really good. When it said install the latest Android v6 it obviously means the previous latest not the current latest
Just in case anyone else is having the same trouble I was:
Using SP Flash Tool load the 20160810 ROM available here: https://forum.xda-developers.com/elephone-p9000/development/rom-elephone-p9000-20160810-t3445897
Then, also using SP Flash Tool, load TWRP v3.2.1 which is available from here: https://eu.dl.twrp.me/p9000/
Then you can use the TWRP recovery to load whichever ROM you like (LineageOS, AOKP etc, etc)
Once again, thanks very much for your help.
:good:
