[RS988][RECOVERY][UNOFFICIAL] TWRP 3.2.1-0 for LG G5 RS988

[NextDroid]

Thank you @jcadduono for your RS988 TWRP tree!

This is an unofficial TWRP v3.2.1-0 build for the RS988 to go along with the LineageOS build that I made. This is my first build of a recovery. Use at your own risk.

Installation from Stock:

**If your bootloader isn't already unlocked, go to the LG Developer website. You'll need to create an account. You can get the necessary ADB and fastboot tools from the Android SDK Platform Tools.**

If you wish to flash a stock ROM, you MUST flash a root .zip such as SuperSU to disable dm-verity and storage encryption! If you decide to install a custom ROM, and didn't disable dm-verity on stock, you will have to COMPLETELY FORMAT your internal storage. Don't risk it.

1. Reboot into the bootloader with the command "adb reboot bootloader" and issue the command "fastboot flash recovery twrp-x.x.x-x_rs988.img", replacing "twrp.x.x.x..." with the location of the TWRP image on your drive.

2. Once it is done writing the image and says "finished," detach all power sources and remove the battery. This step is important—if you reboot into the system instead, TWRP will be overwritten by the stock recovery.

3. Reinsert the battery. Then start the phone, holding down both the Volume Down and Power button. When the LG logo appears, quickly release and re-press the Power button, continuing to hold Volume Down. This should bring you to a Factory Data Reset screen.

4. Confirm "Yes" on the two prompts (don't worry, no data will be deleted—we've overwritten the stock recovery) and you will be in TWRP.

Make sure to follow these steps as written, and make backups if necessary. You wouldn't want to risk saying "Yes" and actually wipe your data, right?

Working:
It works. If there are any problems, tell me.

Everything works! Thank you for an updated recovery!

Phew. I was kind of unsure... I couldn't get Magisk to stick, so I was unsure whether it was problem with the recovery or not.

Thank you!

Magisk sticks!

Magisk sticks!

All right. It may just be an issue with my Lineage build then.

Also @Awkydee have the battery levels been reported accurately? I'd had this issue where it always reported 50%, and even a full reboot didn't solve it. I'm pretty sure I did a battery re-plug and it didn't help either.

 

[Awkydee]

No.. it almost always reports as 50%.

 

[tristan6100]

I might just buy a rs988 now that's it's got a new recovery and lineage os thanks!

 

[de_hammer]

On the subject of the battery percentage reported, the percentage always seems to start at 50% and then change to the correct percentage after about a minute or so. I'm not sure if this just means it checks battery percentage on a long timer or if its something else.

I need some help here I went ahead and unlocked my bootloader and I attempted to flash TWRP via the fastboot flash recovery command everything was successful but when I reboot my phone and try to type in ADB reboot recovery it just brings me 2 a stock looking Android recovery screen. With a little bit of research I discovered that I needed to apparently power down the phone after flashing TWRP then hold the power and volume down button until the logo appears and quickly release them and hold down again while the logo is still showing to get into TWRP for the first time but when I do this the phone just proceeded to show me the security warning due to the bootloader being unlocked and then it boots normally every single time I'm very confused am I doing something wrong?

Yes, I agree, some instructions given on various sites are obscure. This is what you need to do:

1. Re-flash the recovery via TWRP.

If you're running stock, I believe that the recovery partition is overwritten on boot.

2. After it's done flashing (be EXTRA sure that it is), detach all power sources and remove the battery.

3. Start up the phone, holding both Volume Down and the Power button. When the LG logo appears, quickly release and re-press the Power button, continuing to hold Volume Down. This should bring you to a "stock-like" screen.

4. On the two prompts, select "Yes" on each one. You should then be taken to TWRP. Your data will not be overwritten, as TWRP should have replaced the stock recovery.

Personally, if I were to miss #3, I would reflash TWRP and then start over. I wouldn't want to risk the recovery partition being overwritten and saying "Yes" to actually wipe my data.

Make sure to corroborate with other sources to be sure that this is correct. This is coming off the top of my head.

I finally remembered to say this: instructions have been added to the main post.

Also, I have updated to TWRP v3.2.1-0! Download will soon be available in the main post as well.

 

[NextDroid]

Two announcements!
1. Installation instructions have been added to the main post. I have forgotten at least five times to say this, sorry ><
2. New build of TWRP available! A download for v3.2.1-0 has been added to the main post as well.

 

[Awkydee]

When I reboot into recovery mode and go to wipe> advanced wipe there's no option to wipe the cache in version 3.2.1-0

Sorry, I didn't see your post until now... I can reproduce this. I will look into it.

It's no big deal it's easy to flash back to a previous version. 3.1.1-0 works just fine!

I like your patience haha. Luckily this time I was able to find a solution. The cache partition is now selectable in my latest build. I will upload it in a second.

UPDATE: Fixed build has been uploaded and is available in main post.

UPDATE II: @Awkydee This issue was worse than I thought.
UPDATE: MAKE SURE TO UPDATE TO FIXED v3.2.1-0 BUILD. ROMS WILL FAIL TO FLASH!

Just out of curiosity: Does your version of TWRP have the correct date/time or is it like ours (H850) with a date from last year and a wrong time no matter what you do?

Oh boy... That one has driven me crazy. Having all of my NANDroid backups dated to the 1st of January 2016... Yep, like the H850 problem. I'm not sure how to fix that one :/

I've read that a couple reboots solve the issue, but that doesn't seem to work in this case.

I've had my H850 for almost 2 years now and can't even count how often I've rebooted it - no fix there :laugh:

Every time I update TWRP or change the splash screen the date resets to Jan. 1st 2016 ... I rename every nandroid manually but it sure is a pain in the ... well you know :angel:

I was hoping you might have a solution ... oh well, just 1 more reason to ditch the phone and get a new one when the contract runs out in 3 months
