[Q] How can I go back to 20h from 20f?? - LG Optimus L9 P760, P765, P768, P769

OK I have a rooted lg l9. It just updated to 20h over the air.
Now my bluetooth sucks and is having all these issues connecting to my car. I shouldn't have done the update b/c 20f was working fine.
How can I go back? ?? I don't have an unlocked bootloader or anything, just rooted.
Thanks so much.

Sorry for the late reply.
What you need to do is nandroid if you would like to keep your apps data and stuff.
Go to this thread http://forum.xda-developers.com/showthread.php?t=2136204
From there,.download any of the v20f
Wipe data/factory
Wipe cache
Wipe dalvik
Then restore.
All you have to do then is go ahead and restore your data, now you should be back to v20f

I'm experiencing the same issue. Is there any easy fix without going back to the previous version?

I haven't tested it because I've had no problems with that, but you can always backup the Bluetooth apps, and put in the ones from the v20f version. In theory it may work if the reason behind it is that they changed he Bluetooth apps.

He might have to reflash his img. or radio for bluetooth... I'm not sure.
I forgot.. I haven't been on for a while.
And to degrade, just offline flash back to 20f.

My issue is as below:
I connected my phone to two cars. They both worked fine with v20f. After I upgraded to 20h, one connection works as usual. Another one did not connect. I manully paired it and it worked. But next time it won't connect again. I checked the phone, the paired device does not even there. There is only one device which is the one still working. I did the pair again and it worked but it disappeared next day. It seems to me the issue is the phone does not save the 2nd connection.
By the way, how do I replace the bluetooth apps with the 20f ones?
Thanks!
Update:
I just checked /system/app. There are four files:
Bluetooth.apk
Bluetooth.odex
BluetoothServices.apk
BluetoothServices.odex
My question is Can I simply replace these four files with the 20f version ones? Can anyone here share those four files (v20f version)?

7/26 MR4 Update -Mandatory?

According to http://www.droid-life.com/2010/07/1...feed&utm_campaign=Feed:+DroidLife+(droid+life) there will be an update to Eris phones. One thing I wonder about is they are calling this mandatory.
What happens if you don't install this? I know Verizon tracks who installs patches and I don't want to take chances losing root.
yeah I'm running EvilEris3.0 on my wife's Eris. I'm actually wanting to go back to the stock 2.1 cause shes not happy with how her phone is acting.....wondering if this will put it back to stock or HOW do I flash it back to the stock ROM?
any help with this would be thankful.
Ok lets not, panic. You need to read the entire thing, and point out that if you have MR3 then MR4 is mandatory but if you only have MR2 then it is only recommended meaning if your current rom has OTA working and you have MR 2 you will be able to ignore the update. If you have MR3 (MR being maintenance release) the update will be eventually be installed for you if you don't do it voluntarily. and you cannot get a replacement for any problems that this is suppose to address if you do not install it
Hey this shouldn't be a big deal. This same update was sent out sometime at the end of last month and those who were rooted were able to root back instantly. Even the 1.49 people. (Assuming you have luck with ADB recovery)
So it will just temporarily remove root?

Pretty much from what I've seen.
And all we have to do is reflash recovery like we did the first time? That's not so hard.

Put her on Ivan's Eris_Official.
No strange/unpredictable behavior. Ever.
I'll just wait for someone to run diffs on it vs the leak4rombase version and see what we can get from it.
Okay with this new root method and all I'm curious as to know if this MR4 is going to stop us from rooting this method. The old method wasn't stopped, but obviously not everyone can do that method.

[Q] No Sounds (Ringer, Notifications, Alarm, Music, Video, etc.)

Hey folks, I've done a bit of searching, but I've yet to find anyone with this specific issue with my VZW S4.
All of a sudden I do not have ANY sounds what so ever....I've tried working with settings (sounds, adapt sounds, etc.), rebooting, clearing cache with CWM, pulling the battery. I do have sound from headphones.
Yesterday evening I went to a doctors appointment and muted/put phone on vibrate (don't remember which) and noticed when I got home and returned to normal sound mode in the pulldown that I no longer had any sounds....
I have a Rooted stock MDK...I have not cleared or wiped to factory settings and I've never installed a custom ROM....only rooted and have CWM Recovery (did this about two weeks ago).
Any clue/ideas as to what this could be? Will wiping with CWM clear it up? If I wipe to factory settings, will lose root?
Same issue

Well, I performed a factory rest with CWM Recovery.....no luck. Still no sounds at all....no notification, speaker, alarm, ringer, etc.
Has anyone else experienced this besides the above poster??
Maybe try restoring stock MDK through Odin. Then re-root. Make sure you don't take the OTA though.

No Sound At all
Sorry to revive but I wanted some advice
I bought my S4 with VRUAMDK firmware used hence I seriously doubt I can ask Verizon to replace it.
when I got it it tested fine I made calls
after rooting it just stopped making any sounds or phone calls, (I'm pretty certain I followed the rooting instructions correctly)
tried unrooting, going back to stock and rerooting and trying several ROMS I still have no sound whatsoever no headphones nothing, it does eventually detect the headphone if plugged in, even in the diagnostic menu sound doesnt work
I can browse using mobile data I can attempt a call and the other phone rings but the dialer doesnt work after placing the call the phone hangs or restarts sometimes.
everything else works I can send and receive text messages, emails, cameras work. etc
if this is a hardware issue what needs to be replaced? any idea whats the best way to get this fixed?

[support] That darn bootloader

Hello.
I know what you are thinking.
Oh no, not another n00b bootloader thread.
Sorry, but sadly it is.
I'm on stock JB 10D MetroPCS MS 769 10d.
I was reading through the Internet, but I'm hard of eyesight and the strain is really starting to stress me. I've never had a phone that seemed harder to unlock(the bootloader). I see many threads and it is really tempting to get a newer rom that will save my battery and all of my troubles.
The only problem is, each tutorial I come across has lead me in a million different directions. Some are dated back from June of this year. I would like an updated method, and of course being the newbie I am, I don't want to try an old method and turn this phone into a paperweight.
I have researched that the T-Mobile ROMs will work on this monstrosity. I know about 2nd init, clockwork mod, have unlocked the bootloader on a tablet. Have been following DROID since Froyo.
I need a sure fire way to do this. I'm sure some of the new guys around here would like a sure fire method.
Let me just brief.
I am familiar with Clockwork mod recovery.
I know basic Terminal Emulator commands.
I run Linux
I know given the right instructions how to Unbrick
My device is currently rooted using the Chinese method, was able to properly install SuperSU and get rid of the Chinese version.
I am aware that the process somehow involves firmware with an inverted screen.
There are so many guides and tools, I've used LG Support tool before, and my final question is...
How the heck do I unlock the bootloader on an MS769 Optimus LG with stock L9 10D firmware?
And yes I've tried the search feature and just got even more confused.
Sent from my LGMS769 using Tapatalk
.lAfter doing some research, I've got everything done up to flashing the 20B firmware this is the point of no return for me. The only thing I haven't done is ADB, but that comes with software mode right before the flash. I'd like to go over this with somebody to see if I have everything set correctly.
Also I need a good copy of the 10D and the European 20B kHz.
... And I'd love to be able to get my paws on the Metro radio... Just in case... For jellybean of course.

Unfortunately there is no simple way to unlock the bootloader, I also have the Metro PCS LGMS769 and managed to unlock the bootloader with a little trial and error and as of the time of this post im running PenberRom5.
Keep in mind that no matter how badly you might screw your phone up, as long as you have a pc and an internet connection you can always restore your phone back to factory settings using the LG Support Tool.

Awesome. Thanks guys. I had trouble with flashing kdz files so I had to go over the tutorials with a fine toothed comb, seems I did not have the small server in the right folder on the root of my C:/ drive. I got 10f flashed, that was my "safe" tester. As long as I can get into software update mode it should be no biggie.
Thanks to you guys as well. Couldn't have asked for better support than on XDA. When I am sure that my internet connection will be reliable, I'll go ahead and follow that guide.
Moving my apps to the SD Card would be really nice. This phone is not very well endowed as far as Internal Storage goes. lol
So yeah to repeat I got KDZ flash working, at least on the "municiple" laptop in the folks house lol. I know what I have to do.
First off, I'm dual booting this old piece of crap laptop I have, it barely runs Windows 7...but it works.

Thanks for that report, now we know that it wasn't the rooting method that killed Sound Enhancement.
Is it dead or only working with Walkman?
That is what I have noticed after moving to 136.
It only works with Walkman and does not apply to flac files any more so I ended up with all MP3s and using only Walkman as my player for now.
I stream music. Sliders work but there's no effect on sounds. I check apps running and it's not there. Anyone tried factory reset?

I refuse to update/upgrade until 4.4 Kitkat has been officially released, rooting is EASY and doesn't involve downgrading and causing headaches in doing so...
Current rooting methods take too long to do, it's a pain in the ass!

I haven't tried factory reset, because I plan to root now after this & I don't want to re set up the phone, but I stream also.

Although It doesn't stick a few records loud are better than nothing...

What is the current method of rooting .136 if your bootloaders locked, if any? I was reading about flashing .136 FW infused with root then installing SU from memory card, with locked bootloader, but I thought you needed your BL unlocked before one could flash anything on the ZU???

There is a way to root 136. However, it involves downgrading to firmware 532, rooting, flashing and so fourth. It's easier rooting using an unlocked bootloader, however, you still need to downgrade in order to root.

OT but i'll continue as it may need a little clarification...
If you root 532 and then unlock the bootloader you should never have to downgrade and root again, just wait a week or so for the next upgrade path to become stable in keeping root, but it will normally just be flash FTF, flash recovery, flash SuperSU and maybe a patched kernel (I think well will need another patched kernel for the 4.4 stock update - just a feeling)
If you root 532 and cant unlock the BL, you will have to wait for the devs to build a stock based ROM with SuperSU cooked in, and follow their instructions closely, but again you shouldn't ever have to downgrade and root again if you wait for the Stock ROMs to appear. It tock all of 3? days for the 136 update to have rooted ROMs on the forum
I had the same problem as the OP after the update. Only owned the phone a matter of hours then connected it to my PC to down load files and the Phablet updated then the problems started?
Not uncommon in the technology industry but non the less rather annoying.:crying:

UPDATE!
I got sound enhancement working with 136 for FLAC and any other app. As I recalled I had other issues before when running non 6802 ROMS on my phone, I was still holding on to some hope that a 6802 based 136 ROM would be the one that will work...and IT DID!
I just flashed the 136 from the NUT thread and it is all working great.
Well how for stock non rooted:'(
