[LG G7 ThinQ  Questions & Answers] Garlikus:
I had the very same problem as OP. I tried to install pie with LGUP (G710EM20b_00_OPEN_EU_OP_0508.kdz) but ended in fastboot loop.

After whole night of trying different things (being a noob means less sleep) I managed to run the phone in download mode. Starting from there I was able to install my previous rom. Both failed update and rescue operations were done on Win 10.

What I tried and didn't work:

- Fastboot --set-active=a

C:\ADB>Fastboot --set-active=a
Setting current slot to 'a'...
FAILED (remote: Slot Change is not allowed in Lock State)
finished. total time: 0.003s

- Unlocking with unlock.bin. Didn't save the msg but saw it somewhere in another thread. I needed to install/point drivers first because the device was not recognized in Win.

- Solutions for G6 for going into download mode. The download mode icon was displayed for a second and then going to fastboot again.

- LG Flash Tool 2014 - I just followed a guide for older phones but it didn't work. Didn't try again.

What did work:

1. I found this post on reddit (remove spaces or PM me, I'm not allowed to post links):

https:// www .reddit. com/r/LGG3/comments/2qe5sr/in_need_of_serious_help_stuck_in_fastbootno/cn5f2qr/?utm_source=share&utm_medium=web2x

Quoting the post

2. I used LG_Firmware_Extract_v1.2.6.1 and extracted dz file from aforementioned pie file. The I extracted two laf files for the kz file. In my case they were: laf.img_180534 and laf.img_81990.

3. I took one of these files (sry, don't remember which one, but they have the same size - didn't check if they're the same) renamed it to laf.img and put a folder where fastboot.exe is.

4. I did

fastboot boot laf.img

and voila: the phone was in download mode!

5. After that LGUP the previous rom and the phone is working again. Here I needed few tries. At first the were some problems, then I tried different combinations (1.14, 1.15, w/ and w/o uppercut). I think LGUP 1.15 (1.14 with patch) did the work. I was able to "refurbish" the phone.

Hope it's useful for others. If anyone could prepare a guide from this description or/and tell why it worked - please feel free to do so.

I think I will wait some time before trying pie again :)
[LG G7 ThinQ  Questions & Answers] davinik84:
Thanks for you guide.. I follow it but unfortunatly after "fastboot boot laf.img" I get this message from my LG:

"Your device has failed a routine safety check.... it will reboot after a while.."
[LG G7 ThinQ  Questions & Answers] Garlikus:
I recall I also had some error msg, it could've been the same. Now I don't remember what I exactly did next as most my actions were more or less random. Either I tried the same command but with other laf.img file (from the rom I used before), or I tried to restart the phone into download mode (vol- and power together and then vol+ after screen goes black) or tried the same file again.

Hope it helps.
[LG G7 ThinQ  Questions & Answers] domenico.dalpiaz:
I have the same problem as well. I follow the guide but I received the same error message
[LG G7 ThinQ  Questions & Answers] Garlikus:
Check if the phone is recognized in LG Bridge. If so, then choose update error recovery from software update tab. Again, I don't remember if it worked immediately or did I need to reinstall drivers and/or choose a proper driver in device manager (generic ADB vs LG...) and/or restart the phone.

[LG G7 ThinQ  Questions & Answers] isavoro:
similar problem here. tried method in post #13 but no success. only achievement done i managed to put it stuck into boot logo instead of fastboot but no dl mode. i think it may depend on which laf.img you push via fastboot. i tried both the laf.imgs found into the pie's kdz with no success. tried to unpack my old oreo kdz but the laf file is in .bin format and cannot push it to the phone. i think we need an older laf.img.

or maybe i'm doing something wrong because i'm facing this for the first time in my life. is there a way i can use fastboot boot command with laf.bin?

Cross flash back to stock Oreo and try again.
[LG G7 ThinQ  Questions & Answers] isavoro:
you're missing the point of this thread. the aim is to recover phones who are stuck in fastboot mode without download mode, phones bricked by LGUP, with wrong dlls or who knows why, phones who lost download mode.

Got an LG G7 (ULM) today and pretty much immediately borked it trying to force update it to PIE using LGUP. Fastboot loop, no download mode, didn't unlock the bootloaded prior to doing this. I'm getting the security error message when trying to flash laf.img but the only lafxxxx.img I can find in the DZ is laf_81990. I'm wondering if OP (or anyone) has the laf_180534 file referenced in the thread? Also, if anyone has another solution with the remote flashing or whatever, link me up with someone. I just want this phone unborked.

[LG G7 ThinQ  Questions & Answers] v_orion:
Hello!. I bought my cell phone today, it arrives in a couple of days. I have some experience with these things (mainly with Sony cell phones).

From what I understood in this and another post, this serious problem arises when wanting to update / flash the cell phone using LGUP.

Personally, I am not interested in updating it this way, just leave it with the Android version that it brings. What really interests me is to be able to install Magisk and root for which I read that the bootloader must be unlocked. If I follow the instructions of the LG website itself (my cell phone will be an LMG710EM) for unlocking and then those of the post to install Magisk 18, am I at risk of suffering the same problem that has been detailed here?

If LG later releases an official Android update (9 or 10, I don't know if the device comes with 8 or 9) and I update it by this official route, do I also run a risk?

P.S .: sorry for the long text, I wanted to make my doubts well exposed.

Enjoy
[LG G7 ThinQ  Questions & Answers] way2aware:
Thank you, man. For this and all of your contributions for this phone. I'm unbricked. And you prob already know, but the problem which led to the brick was due to updating to the latest version of magick manager when attempting bootloader unlock via 11G and V35 bootloader, something about that version. Using an earlier magisk manager, the bootloader unlock worked just fine.
[LG G7 ThinQ  Questions & Answers] loonycgb2:
Well before the bootloader was unlocked, you cannot download magisk manager and update then use magisk to directly root until the bootloader is unlocked..

Has nothing to do with magisk version, any modification to the boot/system/vendor before boot unlock will leave you with a red triangle as the system will not be able to verify system integrity.

[Android Q&A, Help & Troubleshooting] tesbreag:
Hi, noob here!

I have a Coolpad Torino S (a cheap Chinese Android 5.1 phone) I was using to tether a few devices to the internet. A few days ago it started behaving oddly, so I restarted it. As expected, it restarted and brought up the manufacturer logo splash screen. It then went to a black screen and vibrated non-stop.

It has a non-removable battery, so I held down power until it switched off, but all it did was bring up the logo again (without turning off) and then vibrated relentlessly.

After a bit of trial and error, I managed to get into recovery. I wiped the cache and restarted - endless vibration.

I returned to recovery and factory reset the phone, then restarted - endless vibration.

I've never seen this behaviour from a phone before. I realise I've probably killed it, but I wonder if reflashing the firmware might stop this vibration issue (as it does seem like a software problem). The problem I face is that there does not seem to be a single stock or custom ROM anywhere on the web for this device. One Russian website claims to have the stock ROM, so I downloaded it, but the RAR file is password protected (with no hint as to what the password might be), and so utterly useless.

I'd appreciate any advice on how I might fix the phone or find a ROM!

The model number is E561 (bizarrely, there is a near-identical Coolpad phone - the Coolpad Fancy - that shares the same model number despite having different hardware in several key areas, so I don't know whether using that ROM is a risk worth taking).

Good luck :) ...
[Android Q&A, Help & Troubleshooting] tesbreag:
Thanks a lot! However, that appears to be for the Coolpad Fancy rather than the Torino S (same model number, different spec). The ROM in the link is for a phone with (apparently) half the storage capacity (8GB vs 16GB in the Torino S) and a different version of Bluetooth (4.0 vs 4.1 LE in the Torino S). I think I read somewhere else that the Fancy has a lower res video on the camera too.

Will it be safe to flash onto the wrong phone? Obviously it can't get much worse than its current state, but at least it's vaguely responding when I turn it on etc at the moment...
[Android Q&A, Help & Troubleshooting] Teddy Lo:
Hi , don't flash firmware for Fancy , I will upload on the internet correct firmware for Torino soon :) , sorry I didn't checked that first firmware is for Fancy . Stay updated :)
[Android Q&A, Help & Troubleshooting] tesbreag:
Hi again. Thanks for the clarification!

Just to confuse things more, my phone is the Coolpad Torino

S.

There is another phone called the Coolpad Torino which again is a different phone entirely (much bigger screen and very different hardware than the Torino S).

It is quite easy to find ROMs for the Fancy and (IIRC) the Torino. It's the Torino S that is impossible to find. so if you can help with that I'd be very grateful!
[Android Q&A, Help & Troubleshooting] Teddy Lo:
This firmware is for Torino S verion like in this video! If you don't know what is what send your device to repair center.

[Android Q&A, Help & Troubleshooting] tesbreag:
Thanks for the reply. I don't know if I said something wrong and if I did I apologise - it was never my intention. This whole Coolpad situation is very confusing, that was my only point (three phones, 2 with almost identical names and 2 with identical model numbers, all completely different!)

I did see that video before but based on the images I assumed it was for a manual update to a working phone (as it goes into settings etc). I will look into this solution if you think it is indeed the appropriate file?

Coolpad seem to offer zero support, so even if I wanted to send it to a repair centre, it would be impossible!

Thanks again!
[Android Q&A, Help & Troubleshooting] Teddy Lo:
Hi , no problem dude just I wanted to help you to solve your problem with your device :) . That is truth that unknown device like yours is complicated with support and the only available firmware for your device was that what I send you.

This flash file is for your device Coolpad Torino S E561 (SK3-U00) Dual SIM also you have same new device with same firmware SK3-U00 . Google a little bit this and you will see the new devices has the same firmware version . I know it is shame for support but what can I say to you about is to don't buy unknown devices and if you thinking about buying like those devices do little research about their support and what problems can you face with that device .

I wish you all the best with your unbricking device .

[Android Q&A, Help & Troubleshooting] tesbreag:
Thanks for all your help so far. I've downloaded and extracted the firmware file, and YGDP v4.03 as recommended.

One more question... would the Coolpad driver in the Fancy file you linked before be the same for the Torino S? I'm guessing the drivers are the standard Qualcomm USB drivers, right?
[Android Q&A, Help & Troubleshooting] Teddy Lo:
Probably it will work if not use this one:

[Android Q&A, Help & Troubleshooting] tesbreag:
After a great deal of messing around with different versions of YGDP and various CoolPad drivers, I finally got to the point where YGDP was able to find and transfer data to my phone.

Many thanks for your help!
[Android Q&A, Help & Troubleshooting] tesbreag:
An update on this, a year and a pandemic on. The phone has died again, and this time YGDP won't bring it back.

It is failing with a flash write error, so I can only assume this is now a hardware fault, unless any XDA geniuses can suggest anything further to try? YGDP gives the following errors:

12:32:38 CELL0: Start to download emmc_appsboot.mbn file ...
12:32:38 CELL0: transmit emmc_appsboot.mbn file size info OK

I can still get into Recovery (which also flashes up a litany of cache read/mount errors), and have tried wiping caches and factory resetting multiple times.

Any final suggestions before I consign it to the scrapheap?
