[TEST-TWRP][LL] @all LOCKED H81x users: I need your help :)

[TheMadScientist]

Nice to see this, my LG bootloopped long ago when I started so it's nice to see someone completed this idea

killer for those of us that are left lol mines so stinkin old now ive sold it 3 or 4 times over everyone ive sold it to loved it so much most of them went and got v20s and give me back the g4 i got a gs7 and a note 5 with the note full port on it i run as my dailys. so like i said if i was to hard brick it rite now im not out anything and ive got a octo box and jtag kit so i may be able to fix em after all

so as op said do not mess with boot or recov partition remeber u still have locked bootloader
but this opens doors for say on ls991 stock based zv6 roms as long as when theyre made and flashed u use the stock zv6 kernal or i would assume flash any said in my case lolipop rom only and restore orig boot partitions will test this therory out to see if i trip the lg sigs and get secure boot errors

It opens the door to any custom ROM u want to build. LOS, RR , ...

tbh i re-wrote 90% of it and added some other ideas but without your try i may had given up! It directed me to the correct path to do that many thanks! :highfive:

i hit my thanks for the day more are coming i guess im thinking short term as in cm and aosp dont use stock based kernels which then would set off the lg sig errors rite or is that more short term thinking

This sounds awesome. Give this man his bounty when this is all over. If my G4 wasn't my daily driver I'd contribute to the cause as well

I'm new to efidroid and never used multirom before but both give the possibility to install other OS on another partition. thats why i work on the efidroid port as well..
Both can be booted by FIsH..

Confirmed to work devices (as of 2017-03-14):

• H815 International - unlocked (Thanks @steadfasterX yea its mine and i have no locked device to test with That's why i needed ur help. but i test without touching the boot chain so its similar to locked devices.)
• LS991 Sprint - locked (Thanks @TheMadScientist420)
• H815T - locked (Thanks @the_naxhoo)

Important note regarding the SuperSU requirement:
You HAVE TO install SuperSU >=v2.76! I will provide a patched version which ensure that it does not harm your boot partition (@ the beta testers: it is in the same location. Flash it with flashfire or similar).

Where are the H818 , H812, G4-whatever users???

safe is only the death

but serious: The installer supports Linux only atm (Windows users could use FWUL) and u have to take the risk of a soft brick nevertheless.
The chances of a bootloop are very low but I cannot guarantee for anything.
You should know what adb is
you should be able to install Teamviewer for advanced support when required
and be able to log in to the IRC support channel i will provide to you (easy web browser access)

If u feel comfortable with all this write me a PM with subject "FIsH".

Hi, interesting your approach in this work. We thinking it's​ possible to apply in model LG G Flex 2?

Without going too much into detail:
tbh it will work on ANY device from ANY vendor as long as the pre-requiremens written in the OP are met.
and you have to build your own TWRP version for your device.
That's all

For the details i will release a porting guide.

H818P freshly repaired with Lollipop rooted. I might be interested in testing your solution

Can I ask for the SuperSU version? It have to be 2.76 or higher than 2.76 version (including 2.76)???

>= 2.76 means greater or equal so yes 2.76 is fully supported

@ All here
From now on: Please head over all the discussion to here:

https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048

I will release the public versions there as well.

thanks for your patience.

Installation of TWRPinFIsH of H812 ...

Hey not sure if this is still relevant but I'm able to get into Download mode into my H812 using a slightly different method than the one I tried originally. If I just power the phone down completely and hold Vol-up and plug the cable into the computer (don't push power) it boots into Download Mode. I wasn't able to see any connected devices in fastboot but I have to play with it and see if I have the correct drivers installed - I was able to use LGUP to flash a KDZ but not sure the difference.

See photo below - the text in the small box at the bottom isn't visible due to crappy camera on my tablet but it's "USER G70"

Hello ReeS86: I see you confirmed that TWRPinFIsH is working on your H812. Have you run into any issues since you have installed it? If so, would appreciate knowing what they were and if you were able to resolve them. I meet all the requirements for installation on my rooted Fido H81210N and would appreciate confirmation and input from someone who has "been there, done that" on the same phone.
Thanks,S.

No issues to report however you should check out the topic in G4 Android Development that is a couple posts above yours. There is more info on what works and what doesn't. You have to be careful not to flash or modify anything related to the recovery, boot or kernel. This includes any recovery or custom ROMs.

Thank you - will do.

Appreciate you getting back and I will check it out.
