How to enter in diag mode? Everything I read was for LS970 and didn't helped me..
I need this to try repair IMEI with DFS CDMA tool (not sure it's possible since this is GSM but JTAG is way too expensive )
I'm stucked here: Diagnostic COM port shows up but when I connect to the port there's no device... running savvy rom
The only way to fix is jtag. Don't try anything else. You may permabrick. Repairing the phone with jtag costs here about 15 euros.

jtag =/= jig
jig is small cut USB dongle that puts you in download mode, doesn't magically fix bricked phones.
also there are no phone specific jig , they all the same do same thing , an old jig from GS1 days will do the same thing, if you broke your bootloader jig will not help.
jtag is programming board, service centers have those, some people in repair shops got em also.

If you want a JTAG service for your phone I would recommend www.mobiletechvideos.com. I have used them before (not for JTAG service, but other services) and their customer service was excellent!

Whether it will work or not can't say for sure but the FIRMWARE between the 747 and 747m is DEFINITELY DIFFERENT. its not major difference but different and biggest part is different modem or broad bands which in some cases will brick a phones IMEI# to 0's when wrong firmware is flashed. Hope this helps. In your position its probably worth a shot anyways to get back to basic boot able working order then maybe u can recover from there but as for your question yes the firmwares are different

Like I said I can't say for sure for your exact scenario. To unbrick it I would say probably yes and at this point u have little to lose.
Do NOT use i747 to i747M
Do not jtag with RiffBox i747M using i747
EFS will be dead after - NO IMEI
will not even Boot after
Use RiffBox to read from a working one.
Full flesh is the only solution for now.

Hi,
I just got a refurbished LG G4, and i'm unable to reboot to fastboot mode. I want to install TWRP and LineageOS. Before that i have to unlock the bootloader.
I followed this guide : [HOWTO][H815] Complete Guide to Unlock Bootloader + TWRP + Root + Xposed + ViperFX . I'm stuck at "1. Unlocking the bootloader officially" -> viii) ...adb reboot bootloader etc...
I tried on Windows and GNU/Linux "adb reboot bootloader" and "adb reboot-bootloader", with and without administrator/super-user right without any success....
The phone reboot to Android. However the phone can reboot in recovery and download mode.
The phone is still in android 5.1, and come from T Mobile (the phone suggest upgrade from T Mobile).
One strange thing is the dmesg usb connection log on GNU/Linux :
Code:
[195563.124097] usb 2-2: new high-speed USB device number 43 using ehci-pci
[195563.257487] usb 2-2: New USB device found, idVendor=1004, idProduct=631d
[195563.257498] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[195563.257506] usb 2-2: Product: LGE Android Phone
[195563.257512] usb 2-2: Manufacturer: LG Electronics Inc.
[195563.257518] usb 2-2: SerialNumber: LGH81029e8b9d6
The serial number start with H810, and the phone is labelled H815 in the stickers under the battery, and on the info on Android...
What can I try to get the fastboot mode?
The refurbished phone says "H810" on download mode. The IMEI was modified too to appear be a H815, as the stickers etc... The phone is counterfeit...
Someone have/had the same problem?
Settings -> developer options -> OEM unlock enabled?

frankenphone maybe someparts from h810 and some from h815 and manipulated or edited software.. we had this in G2 alot. only wasy to find out was by looking at motherboard its printed what variant it is only looking at it physically. mean to take out on you hand and read the number model.

I requested a refund. The vendor falsified the IMEI and model number. The Android image seems to be frankenstein-like too. It proposes me to upgrade with "T-Mobile" (and fail at reboot), and the default welcome page on the web browser is att.net (after a complete wipe out)...
I don't know how to solve this problem. I need more LTE band (working but it's poor comparing to my Xperia Z1c). I have the band 7, but I need band 3, 20 and 28.
1. Which method (unlock bootloader, install TWRP, etc...) i must use the one for H815 or the one for the H810 ? Which image of Lineage OS ? Logically the H810 one?
2. Is there a way to revert back the phone to its original model and IMEI ?
3. Finding the original IMEI? Maybe with the original SN?
Install LG Phone From and run it,maybe you'll get more information...

I tried LG Bridge, and it detect the phone has a H815. When it tries to upgrade the phone, on the reboot, on download mode, the phone show information like H810 H81010o, and stay stuck here. The software on windows report a fail.
"LG Phone From" report a H815, with the IMEI on the label.
I read that it's possible to modify the model name(here on XDA) and the IMEI (QPSK or LG "something" by Octopuss). Seem's that some vendor in Aliexpress are not very straight...

Is there a way to revert back the phone to the correct model (H810) ?
I read this Lg G4 F500L - Fixing and Converting to International H815 Model
The solution is to modify the TOT file? How to do that ?

Did it. The discussion is on the way.
Opened the phone, the mainboard is labeled VS986.
So :
-Download mode claim H81010o
-Android show H815
-Mainboard is labeled VS986
So my phone is a VS986 (ie the mainboard). Is there a way to make it a VS986 for Android and Download Mode, like the mainboard was originally?

I tried the KDZ for Verizon (VS986). LGUP fail because the model reported is H815. I will try with "LG Flash Tool 2014".
Another solution could be writing directly the eMMC with eMMC DL Tool. I didn't find the VS986 bin file for now.
I successfully flashed the phone with "LG Flash Tool 2014".. It's now a VS986 (claimed by android) and as labeled on the motherboard.

is all working .. too bad you wont have unlocked bootloader.
Yes, and :
LTE isn't working (verizon limitation)
Sticker labelled H815
What I've found out about my G4 Frankenphone so far:
- sealed box said LG G4 'dual LTE'
- sticker on phone under battery says H811 and has a valid corresponding IMEI
- phone model in settings/device info is H810 with IMEI 0! :crying:
- download mode screen is in Korean with some mention of F500L v11d...
- the phone came rooted running LP
- it is registered on my network, working 4G LTE!
I've been hoping to custom OS and reinstate a sensible IMEI but from everything I've read and not been able to do (can't flash anything and always coming across 'barriers') and to avoid bricking the phone, I am giving up. I have contacted the vendor and told him to find a replacement, clean G4 or clean G3. Seems to me that the G3 is a lot more versatile in terms of the support, especially here, for it. I shall miss the spec. of my G4 and it's greeeat camera!
- unless someone can convince me otherwise or point me to a G4 FrankenRom link and successful instructions!
Using JTAG or USB jig? Is it possible? How much it will cost for JTAG or jig? I went to service centre and they said that motherboard needs to be replaced and that costs 200$ which I don't want to spend. Have anyone tried JTAG or jig?
JTAGs is no longer available in phones. There's no magic jig and it all depends on your issue. If you have bricked bootloader and phone is still detected as QDLoad 9008 etc then it should be possible by flashing blankflash files current or newer than your previous firmware. If it's not possible, then there are ISP points available on the board so any store who have hardware for reading/repairing eMMC should be able restore bootloader using that. Keep in mind that this requires to get the display out.

So is it worth it to repair eMMC or just send my phone to lenovo professionals?
If you find a decent shop that have the required hardware and will charge you less and this in fact is your problem, sure.
