Hi everyone. Do you know where can I download a stock ATT firmware for lg v35? Mine is network locked and I have the code to unlock it but I have to be on original firmware. Please help me if you can. Thanks

I am unsure how to flash each partion with QFIL. It is looking for an mbn file type but the zip contains bin files
[LG V35 Guides, News, & Discussion] hachiroku:
this is the newest Android 10 E version OEM ROM available for the V35, but also the AT&T version. the latest Korean rom uses D version of the base ROM.
[LG V35 Guides, News, & Discussion] hachiroku:
anyway to direct on how to flash these partitions using QFIL? i'm currently stuck on Korean 10D but would like to move to the AT&T as this is an AT&T branded V35.
[LG V35 Guides, News, & Discussion] cmrntnnr:
Flashing the ATT partitions using qfil is annoying and complicated. There is a mismatch in partition sizes. I am not sure how to fix that. The other issue is that the partitions have to be flashed one by one in qfil. Basic install and use of qfil is provided in the thread titled Bootload Unlock and Root Instruction.

I still use a V35 as my daily driver on the ATT network. The base ROM is the Korean A10d. It is localized to NA and works perfectly. Localizing is probably a better option than trying to go to an ATT Rom. Cloud has good instructions on how to do that. You can apply cloud's instruction to the ATT OP partition.

Good luck and nice to know someone else is still rocking a v35.
[LG V35 Guides, News, & Discussion] tiguy99:
Did you ever figure this out? If yes, did you update to Android 10 via the AT&T official update or did you flash the Korean version via the methods described here?

Just wondering what the differences areandhow the user experiences differ between the US AT&T Android 10 vs the Korean Android 10 on this phone
[LG V35 Guides, News, & Discussion] hachiroku:
the AT&T rom is 10E while the latest Korean ROM is 10D. the Korean ROM's are slightly buggy and if using location based time, it'll always think you're in a country not America as it always has the wrong date and time set. years ago, AT&T killed the ability to fully update any older V35's on their network OTA. It never completes download and install and you must have an AT&T sim in your phone for the OTA to register.
[LG V35 Guides, News, & Discussion] hachiroku:
The Korean A10D and AT&T A10E have different sized partitions? thanks for the info. I may just want to localize to North America then. Thanks!

Couldn't you just flash back to AWM android 9 and then flash these through qfil? Or dd out the laf, and flash them through fastboot? I guess I'll unzip this and see what I come up with. I'm on Korean 30D on my ULM and it's flawless, but still interested.
[LG V35 Guides, News, & Discussion] Opistorincos:
I am also waiting on someone to come up with a way for us to flash these files.
[LG V35 Guides, News, & Discussion] Opistorincos:
I took the pain to flash all these partitions one by one on Qfil. OP partition is the only one i was unable to flash due to data overflow error. Asides that, the boot image in the modified partition folder bricked my device. I had to patch the unmodified boot inside magisk and flashed again to get things working. I was on korean Q before flashing these files. I get ntcode error after every reboot. My sim network only came up with 2G and 3G connection. I flashed my original modem files and that rectified it.
[LG V35 Guides, News, & Discussion] Yeedatoy:
Ive been poking around because something caught my eye and i cant find any evidence that proves my theory incorrect. The AWM30e seems to be way older than Korean 30D. The build number is exactly the same yer the security pacth is from APRIL 2020 while my security patch is January 2021. Oddly it seems like the awm android 9 updates were labled as AWM30 considering 30c was android 9. Is everything on the internet wrong? That's definitely possible but a reddit user also posted about getting the update to 30E a long while back and posts as well that the security patch is April 2020.
[Android Head-Units] adir 25:
Hello, I wanted to ask which ic amplifier would be the best for me for the car in terms of sound music,I have some doubts between the Tda 7851 or Tda 7838 or Toshiba Tcb001, by the way I have an external amplifier of kicker 250.1. Thanks!
[Android Head-Units] ExtremeMOD:
This depends on what you have right now. The most common hardware mod is TDA7850 with a 10,000 mf capacitor. Personally, I disconnect it from internal power altogether and drive it with a 17v-18v 10A power supply. Bear in mind that TDA7850 requires proper cooling so be ready to add additional heatsinks and a temperature-controlled fan (you don't want the fan to be on all the time, only when cooling is required). Example in the pics.

View attachment 5391107...View attachment 5391105

If you have an external amplifier and it's good (at least 300 real Watts), then I would remove the internal amplifier chip altogether and instead optimize the hardware for using an external amp.

More info on the mod itself can be found here and here.
[Android Head-Units] adir 25:
Ok, I understand, in the case that I have an external amplifier how do I optimize the hardware for using an external amp?
[Android Head-Units] ExtremeMOD:
Guides can be found here and here.

This will require the removal of the internal amp and soldering other components onto the motherboard
[Android Head-Units] marchnz:
Removal of the TDA power amplifier is not necessary, you could consider grounding pin 4 to place TDA7388 into standby and decouple signal inputs via 1k resistor to RCA leads for connection to external amp.

Another option could be to cut or lift TDA power supply leads. However, leaving the TDA in place will not affect audio.

Despite what the Russian mods suggest, soldering 1k resistors, carefully and supporting with a small amount of suitable glue is OK.
[Android Head-Units] marchnz:
There is so little difference (other than being mostly counterfeit or knockoffs) between these Power Amplifier ICs there is no "best".

If you want a real and measurable difference, install an external power Amp.
[Android Head-Units] ExtremeMOD:
Real TDA7850 (properly cooled) powered by 17-18v supply with 10,000 mf cap, with proper power and grounding cabling with correctly configured Viper4Android will perform on a level where no external amp will be able to complete when it comes to price vs sound quality.

If you choose external amp then you'll need to throw in a DSP unit as well. All that will cost more than some are willing to spend.

YD7388 and TDA7388 are complete crap however.
[Android Head-Units] adir 25:
Ok, I got it, I have a dilemma between these two -View attachment 5392433
[Android Head-Units] ExtremeMOD:
None of these are YT921xxx or Rockchip based type, so personally I wouldn't know how to do any modifications on any of them
[Android Head-Units] marchnz:
Unfortunately, the datasheet shows a different perspective, however goldern ears may vary. If you like it, that's great.
[Android Head-Units] marchnz:
As I said earlier, there's little to NO difference between the power amps they use, except that they're mostly counterfeit devices, so it's *luck of the draw* what you end up with.

If your concers are audio quality, these Chinese knockoffs are not for you. Also, doing misinformed things like running the power amp at manufacturer rated maximum supply and fitting a giant heatsink to in in hope of it lasting longer than a short period of time - won't help either. I had originally typed 'dumb', but realized that it's not polite.
[Android Head-Units] marchnz:
Just to be super clear on this question: Which amplifier is better?

The answer is none.

The power amps used in these devices are all so close in terms of output power, the difference is insignificant.

Wanting quality Audio? The cheapest units are not for you, with the more expensive units not necessarily offering any better "quality".

Wanting power to drive your speakers/annoy - purchase external power amplifier(s).
[Android Head-Units] ExtremeMOD:
Clearly you have not had any experience testing TDA7388 or YD7388 with true TDA7850-system described above side by side.

Only relying on datasheets is like trying to understand what sound will be like by reading datasheets of speakers...

Please refrain from confusing people who are most probably on budget, trying to get the best out of their Android Head Units.

Max conditions for any electronic device can be successfully applied with proper modding to support the output. They will not break.

Many times the shortfall is the cooling, not the power output capacity. And it's not "just heatsinks", it's an end-to-end temperature-controlled cooling system.

I will agree on that if you can afford a proper external amp and DSP, that that is a better choice. And many of these units can be optimized to deliver a respectable performance with external gear.
[Android Head-Units] marchnz:
Testing, interesting.

How were the before and after tested and against which ICs.

No, reading IC datasheets is not "like trying to understand what sound will be like by reading datasheets of speakers".

One could however make cabinet and crossover decisions based on speaker datasheets, that is possible.

If at the end of the design, your speakers added some sort of magical sound to the reproduction, the calculations are in error and the design is a failure.

This discussion is however like comparing two cheap rubber bands and arguing one is better because you can stretch it further.

Since you mentioned speakers, running a speaker beyond xmax is analogous to operating the amp IC at its Vmax - impending failure.
[Android Head-Units] Allan_Hun:
When data sheets clearly shows THD >10% and skyrocketing above 100W output. You don't need any test to know that it will not sound very nice powering 4-8 speakers and a subwoofer!

But it might sound ok with efficient stock speakers.

For undistorted power you need an external amp. But these units are rather noisy and garbage in equals garbage out...
[Android Head-Units] ExtremeMOD:
Subwoofer will pull the most amps which is why it's highly recommended to have an active sub, which let's face it - most car audio lovers will already have. Even a compact underseat subwoofer like Kenwood KSC-SW11 150W will make quite a difference even in an SUV sized vehicle.

A trimmed TDA7850 setup in a up to 8x (4+Ohm) stock speakers + active sub, will deliver some respectable results in combination with a properly configured Viper4Android.

With passive sub, I probably wouldn't bother as it would choke TDA7850 even with the suggested mod. Simple physics.

I tested a 4 × 4Ohm speaker setup with a midsize passive sub and it wasn't awesome. Was okay but barely.
[Android Head-Units] Allan_Hun:
Stock speakers have tiny motors designed for 15 RMS watts.

But if you want something better you need power. 50W is better and 100W is even better. But if you care about sound guality you definitely don't want 20% of the output to be distortion. So a tiny single ic amp is not up for the task.

So if you want cheap sound quality purchase a power amp. Lot's of nice used amps available for 100$. So that is the route I would recommend instead of trying to mod the internal amp.

But if anyone really want to spend their time modding I'm not stopping anyone...
[Android Head-Units] ExtremeMOD:
Well, getting an external amp will still require hardware modding of the cheaper Android Heads Unit for optimal output and you'll need to throw in a DSP unit to at least partially offset not having Viper4Android.

I think if you put it all together it'll make more sense than comparing watts and units/components one by one.

The sad part of it all is that no Android Head Unit, not even the most expensive ones can deliver any meaningful audio experience. I compared the sound quality of a $800 Android Head Unit and a $100 one and it was barely noticeable.

The newer Qualcomm Android Head Units come without internal amp but require almost no modding to deliver good output. Granted, these new units utilise the fibre connection so not really a fair comparison.

I'm actually using one myself with an external Harman Kardon setup - and it's almost good enough but I'm really missing Viper :) Still looking for a hardware alternative but it would require quite a stack of hardware... DSP, EQ, Dynamics FX unit etc etc..
[Android Head-Units] Allan_Hun:
I used to have a 100$ android HU feeding 3 amps through a Dayton DSP.

At low volume the s/n ratio was quite bad, but at normal listening volume it wasn't bad and I could not hear it with the engine running.

So I would like to know what you think needs to be improved about the preouts and how?

What is dynamics FX and what do you miss from viper?
[Android Head-Units] ExtremeMOD:
I normally test the sound in my workshop as I have different car speakers and home speakers setup so I will hear literally everything... Car engine noise is therefore not present.

The radio sound is not great but can be improved by removing a few internal bypass capacitors and changing some others to much more powerful ones. The radio sound is better on units with NXP radio chip that supports RDS but frankly I'd rather listen to DAB or Internet Radio as that sounds goes through the "normal audio channels".

There are ways of "cleaning up" the output from RCA's by modding internal components. I'm yet to test it but can tell you for sure that the RCA outputs are "noisy". I compared the audio quality of Kenwood and Sony pre-outs side by side with one of the $100 Chinese Androids, and at least in lab environment, the difference was noticeable.

Viper4Android is a as powerful audio processing tool as any piece of software can deliver on an Android. Coming from a studio recording background (used to be an audio recording engineer and composer), I see this as a complete tool to perfect the car audio by softening the bad and boosting the good.

Dynamics FX for example allows you to utilise compression of certain frequencies at certain volume levels so that no matter of how quiet or loud the overall volume is, you sound stage will be perfectly balanced. It's a bit like fluent EQ.

And there are a number of other modules that will allow things like adaptive stereo imaging, frequency boost, distortion prevention (I have pushed TDA7850 to it's limits with no audible distortion), noise cancelling, delays, reverbs - pretty much any studio effect you can think of.

It is a complex tool but once done right, it's really impressive.

To give you an example, it took me 8 hours to properly calibrate the sound in our previous car that had one if these Mediatek Android Head units (modded to the teeth of course). Using stock BOSE speakers and 1 underseat sub in a fairly large SUV, it was uncomparable with the stock amp setup. Yes I spent a month modding the unit itself but for $200 I paid for the head unit and any spare parts for modding, it sounded like a 20-30 times more expensive audio setup and the best part was that it was a powerful Android as far as head units go.

I tried installing fastboot images extracted from ozip files but vendor and system images gave partision not found error and I didn't have a windows device I had ubuntu

I installed .ofp by this way

I had bootloader unlocked, please report if it works without bootloader unlocked

1.Download .ofp file of your device

https://c.realme.com/in/post-details/1271381271037083648 this is link for Indian version from realme's website

2.extract .ofp file, I did it using https://github.com/bkerler/oppo_decrypt (This took awfully long time for me)

3.Go to fastboot and flash all the files through fastboot commands

( 1. fastboot flash boot boot.img 2.fastboot flash super super.img 3.fastboot flash vbmeta vbmeta.img 4. fastboot flash vbmeta_system vbmeta_system.img 5.fastboot flash vbmeta_vendor vbmeta_vendor.img 6.fastboot flash userdata userdata.img)

in this order

4.go to stock recovery and format and wipe data

5.Now you should be able to boot
