That's a good idea, I've never taken the plunge converting stock LG apps to Google as I'm not an enormous fan (prefer AOSP) but I'll give this a try once I'm home and fully recharged to see effect on battery life. Figured I'd cycle another day today and check BBS as well.

When I installed it, it didn't "convert" the LG dialer app, instead there was a 2nd dialer app. When I used it, the system asked did I want THAT app to have the permissions. I said yes.

You can probably then also "freeze" or disable the LG dialer app?

i've just suppressed it from app drawer via nova launcher options. there's more apps i switched to, lg's look doesn't suit my likings. all suppressed, no problem, and if you need them, just enable them again (for lg's dialer codes e.g.).

I've just been using "shortcut master" to skip having to type lg dialer code..

So I froze the contacts app as it is the one containing phone and reflashed google dialer.

Battery drain is still an issue but not as much.

Phone app drained 16% being idle from 12am until 6am.

Seems US998 is the better firmware for me; I suppose if the network I had was 4G this would be helpful but it feels as if it's draining more then I actually need. (My network data only goes 3G speeds anyways)

Weird how much original H933 is having an identity crisis. ?

Edit - to be honest the 1 cycle did it; with freezing contacts and using google dialer I now have a fully functioning H933. Battery drain no more.

one thing I also observed.. after a reboot.. the battery consumption would be fine till you make or receice a phone call.

if you did and the battery is fine.. I might do the switch too

Yeah I made calls all yesterday and my phone was fine throughout the day.

My battery is working 100x better now since I've done that; the day cycle probably helped the kernel get back on track too as the first day really sucked (died so fast) but after a day cycle and just google dialer + contacts battery has definitely stabilized.

I used app quarantine (root) to freeze contacts as titanium backup wouldn't let me.

I'll post my battery details from bbs today once I'm close to empty.

drop a thanks..

So just read your procedure... From what I'm gathering, booting the phone and configuring everything might modify the OP partition? So have you done a diff of the dumped OP partition vs the stock OP partition see if it does modify anything? This could potentially help in flashing custom ROMs as you mentionned.

I tried but it was a bit too much for the amount of time I had.

Night_1 · Dec 2, 2018

Tried to convert back to H933 for the last 3 days.. always lose recovery and unable to install TWRP... back to US998 i suppose :/

I've followed all the steps but every time I get to step 5...i am unable to open the root shell... I always get a permission denied... Any idea what I could be doing wrong?

Are you clicking accept on your device?
The second you hit enter after adb shell you would need to click accept on your device.

Check magisk and see if 'Shell' is under super user.

Perfect...that was the one crucial step i must have missed.. Thank you very much
Now to get LTE back that was working when i did the DUMP and now its not..Thanks for the help

Well if it wasn't for bad luck i'd have no luck at all, back to US998 i guess.... can get root but no cellular data...oh well

Yeah another user has messaged me with issues with data as well.

I'm with ChatR so unsure if freedom(wind) towers are both using UMTS or not.

I can retain data myself but two days ago I relocked BL and redid the WTF method. I'm currently on US998 again but I'll reattempt fresh and once data is working I'll host my TWRP backup. (Will be 100% fresh so I'm not worried about personal data as there will be none.)

Edit - I changed to US998 as it's battery lasts almost 2 days for me while stock H933 lasts half a day at best. (Most likely due to stronger radios etc)

If you ever do the H933 backup that would be amazing...
I'm not on either of those networks... I'm on Sasktel.. VIp 85 plan... Unlimited voice and data for $85

I think I'm the other user. I had the same experience as you Night_1. H933>US998 rooted>H933 rooted but no data. It seems like Christopherrrg was able to keep data working but its not clear what the difference was.

User @Cordtus says he went through the process. Then he ran into problems after trying to flash a custom Rom after getting back to H933. He seems to have been able to get to rooted H933 with data before that, but I'm not 100% sure. Maybe he can clarify.

I'm thinking about giving it another go on my next set of days off. I just need to decide on what I want to try differently. Maybe the full list of DD bin files, unless Christopherrrg comes up with something else successful before that.

Yes I had data all the way up until I flashed the modified "stock" h933 zip. So I converted to us998 using the Frankenstein method then installed twrp+root and after that I flashed back using partition dl to the 933 (excluding recovery) then installed twrp and root again and then flashed again through partition dl the 933 recovery only, then using shell from within a booted system I reverted to twrp recovery. Mobile data worked through this process but currently I have no mobile data after flashing the modified 933 zip from another thread.

Please don't take this as a step by step this is only the processes I followed through several different threads to come to this point.

So, I did a few tests this weekend, almost broke my phone (DONT FLASH the modified h933 over a Frankenstein H998 phone lol).

That being said, following this guide, step by step seems to work(again like the previous user said, some steps may or may not be necessary). Just make sure to make a backup with LGUP with a stock H933 ROM with data working.

EDIT: Personally, I did not do step 7, which is flash the modified H933 ROM, as it should, in theory (and it worked for me so in practice too lol) be giving me everything that the previous steps already gave me.

Now once coming back to H933 I think the important steps to get data back are flashing back these partitions and changing for example OP_COMX.. to OP.bin :

dd if=/sdcard/modemst2.bin of=/dev/block/bootdevice/by-name/modemst2
dd if=/sdcard/misc.bin of=/dev/block/bootdevice/by-name/misc
dd if=/sdcard/persist.bin of=/dev/block/bootdevice/by-name/persist
dd if=/sdcard/ftm.bin of=/dev/block/bootdevice/by-name/ftm
dd if=/sdcard/pstore.bin of=/dev/block/bootdevice/by-name/pstore
reboot

Hope this helps someone!

These partitions must have been taken from a working h933 phone.
If you just flashed the h933 kdz and didnt check if everything was working fine before doing the dump using lgup, flashing them probably wont do anything~
(by booting it up and making sure data is working..)

Thank you for finishing this up; truly appreciate the few Canadian users we have who are fully willing to tinker.

Sorry I haven't reupdated my instuctions just yet; been sick for a few days.

Finally got it to work. I partition dl to Nougat H93310h_00_OPEN_CA_OP_1124.kdz ...then partion dl to Oreo H93320e_00_OPEN_CA_OP_0320.kdz... from there i had to REFURBISH up to H93320g_00_OPEN_CA_OP_0910.kdz just to get data working (this is what i had to do to get data functioning, my not be required for others) so i could do the DUMP as per @cloud1250000 instructions ... then followed all his instructions but i added "dd if=/sdcard/modem.bin of=/dev/block/bootdevice/by-name/modem" to Step 3...
followed the rest of the directions and BOOM... fully rooted H933 with TWRP

Thanks to everyone involved with this
