[Android Head-Units] Merc129:
Hello

I have a 1991 R129 500SL that has a single din radio slot, so I'm looking for a single din android unit, 2 Din isn't possible in this car without lots of cutting and modifications, which is something I'm not willing to venture into.

I'm looking for a single din android unit with preferably the latest possible OS, iPod control or the ability to connect to a 2.5 external HDD. iPod control is very important to me as my entire music library is on my iPod classic. My second option would be to connect an external hard disk to the unit.

I would like to have a unit that has most of the slots on the rear end with a clean front interface with the option to change button colors to match my ambient lighting.

I've trying to some pictures of my current setup and what my center console looks like, doesn't seem to be an option to post pictures from my phone.

Anyways, any help is really appreciated guys.

Thank you

No one has an idea about single din android units that can control an iPod classic?

Any aftermarket apps perhaps to make this work?

Probably your bet bet is something like this.

There's about 0 market for Single-DIN android, the entire market is double-DIN now.

As for that unit there, it isn't android but the Pioneer units are decent. I've used 2 of them in the past, but double-DIN.

Personally, I have no interest in the motorized fold-out screens. So here's a Joying Sofia unit which is single-Din mount, but with a double-DIN screen.

I hope your vents aren't in the way!
[Android Head-Units] Merc129:
Thanks for your reply.

I did buy the Pioneer 7800BT unit but I returned it the next day, as it tends to stall quite often when playing songs from my iPod and takes a long time to switch between tracks.

Also the Appradio mode is very impracticable, I need to keep my phone connected via usb which means no iPod. Also I need to install a specific Pioneer keyboard on my S7 edge otherwise the keyboard won't show up on the head unit for any input. This means I have to keep switching keyboards in my phone whenever I enter or exit the car. Also you can't really use google maps or anything like that as Appradio One is not true mirroring, I can only see a map with no nav options or turn by turn guidance.

You can use waze but there is a problem with the screen formatting, a lot of prompts are off-screen. It's not properly configured for this head unit.

All in all, it was a very poor effort by Pioneer so I returned it. I saw the joying units but they won't fit my console as you can see from the pics below, and they don't support iPod, and neither do Pumpkin head units.
[Xposed Framework Development] RyogoNA:
I have hooked to com.android.internal.policy.impl.PhoneWindowManager.interceptKeyBeforeQueueing().

Call to Environment.getExternalStorageDirectory() was throwing error "Path requests must specify a user by using UserEnvironment", so I added

Environment.setUserRequired(false).

Then I have aquired storage dir path using Environment.getExternalStorageDirectory() which points to "/storage/emulated/0/" and which is correct existing path.

But calling on new File("/storage/emulated/0/").listFiles() (note: checking exist and isDirectory on File both returns "true") returns "null".

Is there any way I can aquire list of files on sd from xposed hook?
[Sprint LG G4] TheMadScientist:
SO I HAVE TO PUT THIS IN NOW DO NOT DOWNGRADE IF URE ABOVE ZVA YOU WILL HARD BRICK THERE ARE NEW G4 USERS AND PEOPLE ARE TRYING TO DG ON ZVB ZVC ZVD OR ZVE IS A BIG NO NO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

THIS HAS BEEN DISCUSSED MANY TIMES........................................................................................

twrp exploit found waiting on official release. this is a ls991 sprint varient. exploit may and should work on all devices.

i am one of orig alpha testers and great thanks to the man it should hopefully be fully working and ready for mass production soon

if u want to check progress look and thank here but please guys for the love of it no spamming the man he and his time are a great addition to the lg community and myself and everyone here can and should respect that remeber no eta or will u's politly ask and have a great day xda

prequisites so far

must be rooted means zv6 or lower zva or zv9 can be downgraded to zv6 one of the 2 not sure

and kernel must be set to permissive

on a lighter note i hate to rub it in but i got the first sprint g4 with twrp on it
[Sprint LG G4] TheMadScientist:
no flashing yet but did make backups

come one every one wake up lol this is what weve been waitin for
[Sprint LG G4] TheMadScientist:
so ive been up since like 2 or 3 am and steadfasterx was kind enough to take the time do a good team viewer made a few mods

and technicly released a second alpha or first beta whichever twrp now persists through reboots and is permantly on my device
[Sprint LG G4] TheMadScientist:
viper 4 android offic flashed with twrp beta for locked bls
[Sprint LG G4] TheMadScientist:
You know im not one to complain very much. But i am quite upset with the sprint g4 community. I risk my device for the sake of the fun. And not even one thanks. 76 views and nothing. Did any of you ever think that now that this has happen mm will be next mm roms prerooted for twrp.

I make post after post to keep theis device alive and keep people updated. But nothing from the community. Im not asking for money or a place to stay. Just a simple thanks.

3 days after purchasing my device. I tear it apart to do a thermal paste mod which has clearly worked so far. Somethin like 2400 views. And i think 1 thanks

Just proves how demanding the world is this day in age but dont expect to help in return.

Again a thanks goes a long way
[Sprint LG G4] TheMadScientist:
And so every one knows the beta 3 has been released went from a alpha to beta 3 in one day. Thats fricking amazing
[Sprint LG G4] WhoRuJudge:
This is great news, hope it leads to more.
[Sprint LG G4] TheMadScientist:
I am orig lg ls991 tester and prob the only sprint tester. And i can tell u other than flashing modified kernels and recovs rite now just cause it adds to a secure boot error but upon twrp restore of orig boot parts all is good

This will be changing soon with efiboot. But for now this is wonderful
[Sprint LG G4] LaughingCarrot:
This is great news especially after the past...What was it? Three developers claiming to have unlocked the bootloader? If only I was a Dev then I could rack my brain and try to figure out how to beat anti-rollback to get back to lollipop.
[Sprint LG G4] TheMadScientist:
Yea it would be great if every one could enjoy this.

Octoplus box with jtag. I think can do it but 350 bucks.

I oredered one a few days ago. I cant wait i got another lg with antirollback i wanna try it on

Im hoping this will bring in new devs and someone will figure this out too
[Sprint LG G4] TheMadScientist:
The bootloader is still locked. This method hijacks the ramdisk and installs twrp somwhere else. Still have stock recovery too. Which i guess is cool never had 2 recovs at same time before

Like i said earlier no go on flashing anything modified on boot and recov partitions. Still secure boot errors. I wish i had a mm stock kernel zvd id see if i could flash and then restore zv6 twrp.

Has worked in past.

Either way man gets a prize. Hes is working on booting efidroid to multi boot which leaves to install anything ontop of orig kernal unmodified. So still wip but opens the door for rr cm anything through efidroid and dual boot.
[Sprint LG G4] shadow775:
Just want to say thanks to the community for there hard work it's very much appreciated. Also I had a question, I have a lg g4 sprint version I'm on zvb mellow mallow, can it be downgraded for me to install the hack?
[Sprint LG G4] TheMadScientist:
Unfort no. Zva and lower. Untill we find a way to beat qfusing. Which 1 day ofcoarse. No avail yet.

I might try this hex edit software and see if i can modify the antirollback qfuse. Either get all firms to say same as zvb c d or e. Dont get hhopes up yet.

But hopfully got a few theories. Ima start with zv5. Cause im not getting stuck if fail on zvb or higher
[Sprint LG G4] HashtagFTW:
Wow this is really great news for ZV6 users! Hopefully the qfuse on the LS991 isn't un-exploitable like KNOX or something... It would be amazing if Octoplus box could actually do something about the horrible anti-rollback. Thanks for the great news!
[Sprint LG G4] TheMadScientist:
Well i ordered one a week ago. Ima find out. Some claims say it can with jtag. Ive been reading loads of hex edits seeing if i can edit a zv5 boot image to think its got a zv6 qfuse. But no luck yet. Ive been sick all week so far and runnin on about 7 or 8 hours of sleep since monday. So im pretty out of it. Lol.

Aint no smoke or no drink compare to sleep deprivation i thought i was seeing stuff last night. Which i know is possible. Ive been catchin a hour here and there. Everyones been passin around the flu and of coarse im always the last to catch it.

With twrp. Just downgrading boot image to zv5 isnt enough. Im not attempting a higher boot image yet. Im not getting stuck on a unrootable firmware.
[Sprint LG G4] TheMadScientist:
4th test release released today with updated twrp version rc1 op thinks 1 more test realease before going public
[Sprint LG G4] DaemeonZane:
Hate to be

THAT

guy, but those of us on ZVB are screwed anyway, so what's the point? I mean, If you Wanna spend 150+ dollars USD, you can unlock the bootloader on these as far up as ZVA, with a GCProKey. Proof of bootloader unlock support./
[Sprint LG G4] klurrant:
You mean those of us on ZVB, ZVC, ZVD, and ZVE etc etc etc....pretty sure the overwelming majority of Sprint LG G4 owners .....and LG G4 owners

Thanks for the efforts though.
[Sprint LG G4] TheMadScientist:
Yea that sucks. I do i believe i came across one other guy on zv6. Leaves me feeling like a loner.
[Sprint LG G4] brendonsmall:
One more on zv6 here.

Yeah, for those on ZVB+, hopefully this work will lead to a better understanding of LGs anti-rollback feature and allow it to be circumvented.
[Sprint LG G4] TheMadScientist:
Ive been playin with the zv5 boot image. Not hard bricking just secure errors. Im tryin to finv another g4 so i can try the jtg and stuff with it. But no one in my area buys lgs all sammy and iphones. I got a guy lookin for me. I swear mm has been rooted on other devices without unlocking bl ima crack this sooner or later
[Sprint LG G4] Phantisy:
ZV6 here as well. Using UltraPOP 1.51.
[Sprint LG G4] TheMadScientist:
I never could get it to boot. Id love to try it

That will explain alot
[Sprint LG G4] TheMadScientist:
Wheres the link and ill check it out
[Sprint LG G4] DaemeonZane:
I just can't help but feel like this is kind of too good to be true. That being said, multiple people have said they've cracked it, but are holding off on releasing, or can't because it's a company deal, or whatever bs excuse they have.

I've been on A.F. for over five years, and in my experience, once a phone falls back two or so generations, pretty much all development goes out the window, root or not. Having been forced to upgrade to ZVB because of Sprint's replacement crap, I'm in the same boat as damn near 90% of the Sprint market.

The only way this phone will ever really work is when someone scores true bootloader access. I've taken this damn thing apart from start to finish, and I just can't get past the bootloader. I've downloaded every image I can find from ZV6 on, done comparison after comparison, hex edit after hex edit, and found nothing that works.

Hat's off to you, bro, for trying though. I really, really hope you make this work, not just for ZVA and under folks, but for us ZVB folks and higher.
[Sprint LG G4] TheMadScientist:
i feel you ive been through days and days of hex files

mix and matching bootloaders systems weeks of studying and no go people can hack nasa nsa cia fbi but lol if we cant figure out an encrypted bootloader on a cellphone lol

my hats off to all those who have tried. since ive owned my g4 ive so far wasted so much of my life trying to figure it out and for what to be ousted less than 2 years later due to absolutly no development.

the nsa needs lg on there side for system protection lol
[Sprint LG G4] lowkeyst4tus:
I was hoping you didn't give up.. I'm on ls991zve and desperately need root.. I'm getting a pop-up for another update but I'm trying to avoid it best I can. I did notice some people lost their sim unlock after updating.. I solved the issue by calling Sprint then using uicc unlock in settings. They won't unlock if you don't have the previous owner info, had service for less than 50 days or blacklisted..
[Sprint LG G4] TheMadScientist:
I havent just no good yet. Bring up the spirits i brought me g4 back out and made it my primary device again. Doin major maintinence on my note 5. So all my lg softwares updated and goin. Same here no matter what i get secure errors and no way to fool with getting root on mm.
[Sprint LG G4] lowkeyst4tus:
I'm going to try accessing the bootloader again now that I'm sim unlock.. maybe with luck it makes a difference. I notice no mention of the zvf update as far as bootloader access or changes other than security..

---------- Post added at 07:59 PM ---------- Previous post was at 07:46 PM ----------

A second theory.. can we strip down the most recent mm kdz and modify the kernel and system to flash root via qpst.. I bricked a V10 with qpst flashing the g4 qpst recovery, but I'll take it as a last resort almost guaranteed to work. The only thing with that is Linux knowledge is required for converting the gpt.bin to partition.xml.. Partition.xml needed to create msimage via qpst..
[Sprint LG G4] TheMadScientist:
any and all modifying of the images breaks the security

there is no zve .tot zvb or c is the last .tot which fuse count was raised any ways.

ive tried breaking apart and repacking with each bootloader accept unpacking zvb or higher i wont get stuck there but repacking newer mm bootloader and trying to repack lolipop system in it instead.

ive tried zv6 bootloader with zv5 system and it worked but thats loli i still was on zv6 baseband but a zv5 system. dont think it will work for mm yet i would try to repack the rooted system image of zv6 into .tot form.

biggest thing is if we had a zvd e and f kdz or tot i have a converter to exract into either form. but i have to have the base firmware to do it
[Sprint LG G4] TheMadScientist:
now dont go tryin no crazy **** on us and hard brick your device we suposedly have a good .mbn but no working method to flash it and then after flash u have dl mode u still need a working in ure case zve.tot or kdz
[Sprint LG G4] lowkeyst4tus:
All good news.. I will then focus my attention on finding the mm kdz or tot.. if I gain bootloader access I will update as well.. I won't trying anything crazy this time.. I learned my lesson on the V10 I turned into paperweight.. thanks for your input..

Update: still no bootloader access on zve..
[Sprint LG G4] lowkeyst4tus:
Help me understand this one.. will this backup​ boot and system root partition? https://www.google.com/amp/www.tech...l-backup-of-your-android-device-without-root/
[Sprint LG G4] TheMadScientist:
i dont know if it does all of them suposedly there is a way to backup everything unrooted.

but ive never done it.

it could never hurt to try that thought

i know in the root method for us we use the dd commands and if im not mistaken there are dd commands also to backup partitions as we were nuking our laf partition to get into a useless fastboot mode. and restoring i was cheating though i used flshifire to back up and restore my laf.

and only used the dd command to zero it out so again u would have to google that one too.

plus dd way u have to do each partition individually if im not mistaken

i may be wrong its been a long time now over a year so i dont remeber exactly
[Sprint LG G4] TheMadScientist:
/

my last post show that we can get into fastboot but no unlock commands are reconized

similar to this

https://xdaforums.com/showthread.php?t=2708466

but no commands work.
[Sprint LG G4] lowkeyst4tus:
Can we get away with using rootdebugfs generic for rooting? I watch the process on youtube.. Old school but it roots via adb debug.. No custom recovery needed..
[Sprint LG G4] TheMadScientist:
Not on mm. Bootloader needs to be unlocked bootloader checks intengrity of system.
[Sprint LG G4] jfoster38122:
I just want to thank everyone for their time and effort. I gave up on my g4 months ago when nothing was available to root it and I really hate I bought the phone since I can't root it and get all the bloatware from Sprint off it. I will read and do my homework and see if now I can finally root it. Again BIG thanks to all who make it possible.
[Sprint LG G4] TheMadScientist:
I put mine up. I finally got somethin else. But still no root on it either. Zte grand max 2. Killer setup. But cricket and zte have it bogged so bad.

G4 is one of those devices that will possibly never see root
[Sprint LG G4] posvar8:
This is all so sad really that us LG G4 Sprint owners are strong-armed into Sprints "take it or leave it" attitude. Anyway, I have the ZV9, so is there any way to rollback to ZV6? My camera doesn't work and I can't change anything in Apps such as Force Stop and such. Thanks in advance guys and Mad Scientist hats off to you bro! Did a great job for what you had :)
[Sprint LG G4] TheMadScientist:
yes u can roll back zva is the highest

that can be rolled back

download the zv6 tot and flash away brother

root everything is good for you

sorry i didnt see ure post here til today or i woulda answered sooner
[Sprint LG G4] posvar8:
Hi there! Thanks for the reply. I have actually bricked my G4......No download, no recovery...just a flash of the LG logo and then it goes away. It does show in device manager as Qualcomm hs-usb qdloader 9008...so at least it shows there. But I'm trying everything to get a DZ file so I can use the extraction tool and see if I can flash somehow :(
[Sprint LG G4] TheMadScientist:
there is no firehose dll for qpst which is the only program to reflash without octoplus box

might be the bootloop issue call lg they should waranty it but the new device will be updated to zvf or g no root no downgrade
[Sprint LG G4] TheMadScientist:
u tried to flash zv5 or 4 didnt you

zva is only downgradable to zv6
[Sprint LG G4] posvar8:
No, I actually tried to go from V9 to V6 hoping the issues I was having...camera....settings' errors and so on would go away. Do you think now that JTAG is the only way/ Or just get a used motherboard? I actually bought the phone from Swappa so the warranty wouldn't cover a non original owner I believe
[Sprint LG G4] TheMadScientist:
no hurt in trying waranty but yea bassicly paying lg to fix it or a mb which these devices aint bad to ear down it shoulda flashed zv6 though

Here is a thread explaining how antirollback works https://xdaforums.com/v20/how-to/bootloader-qfuses-arb-how-to-brick-t3673622

I'm curious though if you can physically replace the Qualcomm system on chip with one that has an antirollback version of 0 then ground the qfprom lead used to send power to the soc qfprom to blow the qfuses, this way the antirollback qfuses in the new soc won't be blown again as the power won't reach the qfprom area of the soc.

My phone was unlocked with Potato v2.0.1, with working TWRP, rooted etc...

I solved this problem that arose after unsuccesfully install custom Rom, restore backup of stock rom, install update through dload and many many other attempts at improvement of my smartphone :-( No more time again!!!

Probably installing update through Dload will relock bootloader, but in the fastboot mode it says bootloader still unlocked.

Before I did all this, I had an original stock rom.

1: Relock bootloader with PotatoNV v2.0.1 (You need to open case and connect tespoint by wire - look on Youtube, i´ve find it there, also you need "Huawei testpoint drivers")

2: Factory reset

3: Install any update stock rom with Dload (Vol up + Vol down + power)

4: Factory reset

5: Developer options-turn on OEM unlock and USB debbuging

6:Unlock bootloader with PotatoNV v2.0.1 - keep password generated by Potato

7:Multitool 8 for Huawei - in the bootloader state unlock bootloader again - use password generated by Potato

8:Multitool 8 for huawei - install TWRP - it says "Succesfully installed" - TWRP works, root is possible. Yeah!!!

May be this is not right way to solve this, but for me it workś..
