Just read about details about HUAWEI's new stock recovery called eRecovery. It seems users can no longer roll back and forth between stock ROMs, can only roll back to certain available versions.

Always keep your ROM latest: by using eRecovery, HUAWEI will no longer provide individual update.app file for manual update via SD. If EMUI system become unusable, eRecovery can help to update to latest Stock ROM to recover, during this process, user data may be wiped (like a full wipe in TWRP).

What if I want to downgrade?

If during the recovery process, eRecovery still can detect an earlier version of EMUI than your current version, then you can flash it, as a downgrade.

If during the recovery process, eRecovery detects the same version of EMUI as current one, then you have to flash it.

Ouch, didn't noticed OP date. But, if Huawei removed firmwares from their site, where this recovery would obtain files so? Better to remain on fully safe methods like TWRP backups :)

TWRP back-up is always best when messed up.

Seeing all over the section people messing up and then want to rollback but with no file

To me it is the first thing that someone should do as installed a custom recovery

Hey Guys,

I am having a problem with the touch screen on my 8525. Now I'm not exactly sure if this is a similar problem as other screen issues on this site but my phone was working fine then the then the screen stopped responding altogether. I was able to navigate via keyboard but that was it. I did a soft reset and it did not help. I then did a hard reset and the screen went to the setup and wants to align the screen which obviously I cannot do. Did the business card trick, no good, put it in the freezer for a lil bit, also no good. I'm a bit reluctant to open it up yet. HTC said the repair would cost anywhere between $170-270... clearly not worth it... I should just open it up take a look? If so what EXACTLY am I looking to do here???

Please Help Me

Thank you all in advance

I was having some 4G connection drops with my phone, so I tried to do a Factory Reset using a KDZ file, I was on version 20t Android 6.0 Official Rom, with LG UP I tried to flash the 20t KDZ file, but I was not getting past 9%, so tried to downgrade to Lollipop 10C firmware, it seemed that it was going well, but got to 21% during the System flash and and error occurred and the flashing process stopped, so removed the battery, plugged back in and now the phone only boots to Download mode, tried installing all the LG UP files from here and the LGUP_8994_DLL_Ver_0_0_3_23.msi file as well, to no success, also downloaded the 20c ROM and got to 23% but failed again, last resort tried the old LG Flash Tool 2014, but again did not even start to flash the ROM, so I'm stuck now =( and not sure what more to do guys, any help/ideas would be awesome =)

[FIXED]

Simple solution, connection to LG Bridge did it, detected the phone even in download mode, downloaded the proper software and that was it, flashed without any issue =) Me Happy =)

[Samsung Galaxy J5 Questions & Answers] KaushikMajumdar:
After almost a year with my Samsung J500F (2015), I just witnessed partial leak of RAM that took place a week after restart. Immediately after restart, the RAM Consumption by system is normal (550-670MB approx.). This goes higher and higher and ultimately lags the phone after a week with the system consuming about 1GB of RAM out of the total 1.5GB installed. However, everything turns back to normal after a normal restart.

I think this is due to Samsung System Caching.

Any ideas, unproved mindless thoughts and theories are welcome. But I'd actually like to have a solution.

I'm rooted. Please don't suggest custom ROM. I like the stock better.

[Android Head-Units] nk33:
I was hoping someone could help.

I need a new 2 Din, Full Android Car Stereo which satisfies the following:

1) Has 4 channels and a subwoofer out

2) The subwoofer out is of normal voltage (ie 4v or above)

3) There is a built in Gain control for the sub on the head unit

4) There is a built in crossover for the speakers and sub so that not too much bass is going to the speakers and not too much mid/treble is going to the sub

5) the above 2 features will be active and work while using 3rd party apps like poweramp etc

All the other stuff like wifi and bluetooth and OBD2 support is assumed as they all seem to do this.

i would appreciate any advice because whenever i email sellers it takes a day to get back to me every time and the answers are always vague and unclear.

many thanks in advance
[Android Head-Units] Hilari0:
2-4 I think you're asking too much at this point.. :) I don't think any of the chinese Android units can meet these requirements at this point. They have SUB output, but no built in crossover which works out of the box. Some units, I believe MTC of sorts, had the hardware but it wasn't hooked up properly, so some people were able to make it work by soldering in some trace wires on the board and moving two resistors. Not something for anyone unless you have good skills in soldering.

For now, I just use an external 3-way active crossover. It works fine. At the moment I'm using the built in amplifier, but will install an amplifier soon as the built in one isn't very powerful, only about 4x15-18W according to the datasheet of the amp IC they used.
[Android Head-Units] nk33:
Hi mate, thanks for your response.

So what i have at the moment is the head unit below:

https://www.amazon.co.uk/dp/B01CGA5...483542345&sr=sr-1&keywords=android+car+stereo

A fitter came and set up my sub and amp from my old car. The rca goes straight from the sub out of the unit into the amp at the back which powers the sub.

The problem i am having is that when i want to hear the sub i have to turn the bass up - when i turn the bass up too high the speakers crackle as the equaliser is universal.

Someone recommended me a PAC LD-10 low pass line which will increase the voltage to the amp for my sub and give me a knob to control the level....will fitting this be enough to do the job?

can you send me a link to your 3-way cross over?

thanks
[Android Head-Units] Hilari0:
I'm not using a special crossover by any means, just a standard crossover which are readily available. Not sure the specific one I use, but it looks pretty much identical to this one but with a different color:

http://www.lazada.com.ph/boschmann-mobile-audio-electronic-crossover-23-way-xm-3a-9196761.html

The PAC LD-10 will increase the line level yes, so you get a good signal over 4V. As far as I know, this is a pure preamplifier (or signal booster if you will), without any sort of crossover. It has separate controls for left/right, so you can adjust balance, but that's about it. You can read all about it here:

http://www.pac-audio.com/productDetails.aspx?ProductId=264&CategoryID=28

You get them on Amazon/ebay for $18.49 plus shipping.
[Android Head-Units] nk33:
Thanks mate.

Does the sub-out on my unit not limit the frequency to say 120 or 150 and below? So hopefully i will just need a crossover for the speakers...?

So if i need a PAC LD-10 for the sub and a crossover for the speakers will my battery be able to cope with powering both of those as well as the Head Unit?
[Android Head-Units] Hilari0:
When I hooked up the subwoofer in my car to the SUB output on my head unit, it sounded awful. It seemed to play full range sound without any crossover, and the sound was greatly improved when I installed the crossover. I didn't have an issue with it being too low though, so depending on the way your amplifier and head unit is designed, your results may vary. If you plan on using aftermarket amplifiers for all the speakers, I recommend using an external crossover, either one like I use or the one that is built in on the amplifiers themselves, as many come with that already.
[Android Head-Units] nk33:
the amp connected to my sub has a built in filter and gain. The gain is on max but i can only hear the sub properly when i turn the bass up on my equaliser, but it still doesnt thump like it did in my old car. The other issue is that the speakers crackles as soon as you start turning the volume up after that. I dont think i need an amp for the speakers as they can even take the Head Units power as they crackle when i turn it up....unless this is becasue the audio quality is so bad.....jesus i never realised this would be so complicated when i had it fitted.
[Android Head-Units] nk33:
i forgot to remind you as well - will the normal car battery power these devices and headunit...and i also have my amp in the boot...
[Android Head-Units] Hilari0:
Speakers will always perform better with a strong amp vs a weak amp. And a weak amp can make good speakers crackle even if they're far from their max power output, due to the amplifier not being able to handle the load. If you have a car with a proprietary amplifier system which uses weird inputs, it may be a challenge to make it work properly and you might be better served replacing that amplifier with an aftermarket one. Don't throw the stock factory amp away, if you ever want to reinstall the OEM system when you sell it or similar. If not, selling it may give a nice income as some of these go for a premium.

---------- Post added at 01:03 AM ---------- Previous post was at 12:59 AM ----------

Oh, and yeah. A standard car battery and alternator should be able to handle a normal sized sound system, even if it's aftermarket. I wouldn't be worried about installing a head unit, a 4x50W amp and a monoblock amp for the subwoofer. Perhaps I'd go to the step of installing a capacitor if the subwoofer was more than 200W and the dash lights started dimming, but this is usually only an issue if you install a huge sound system. Normal listening levels never reaches high power demands..
[Android Head-Units] nk33:
spot on mate - the major issue with my oem kit is that it was fibre optic from the main head unit to the back amp. However the guy that fitted the stereo for me asured me that the power from the HU would be more than enough to power the speakers in the car...looks like he was wrong!

So in summary i can buy one of these as the amp for the 4 speakers

http://www.crutchfield.com/S-JbbC3Sa3qOK/p_500MRVF300/Alpine-MRV-F300.html

And then get the PAC LD-10 for the sub and that should be me done right? In theory...LOL
[Android Head-Units] Hilari0:
I don't see any reason why it shouldn't work, but I don't know anything about the headunit you have so I have no idea if it has good or bad preamp outputs. It does look like a pretty standard Rockchip based unit, so I suppose it would work fine.

Powering speakers with the built in amplifier works, but only to a certain point. It's mostly good for your bog standard OEM speakers from a mid to low class vehicle. Anything premium or larger setup in a luxury vehicle typically requires a bit more power than the internal one can give. I know they write 4x50W on the box for the head unit, but that number is a peak output power at 10% THD or something, horribly overrated. hehe. Not sure if your head unit uses the same amp IC as the Joying ones, but I checked the datasheet on that and it was at 4x15W at 4 ohms when it crossed the 0.1% THD mark, and you typically don't want to go beyond that. :)
[Android Head-Units] nk33:
ok - i have booked in the fitting;

- a 4 x 50w rms amp with variable crossover for the speakers

- Line driver for the sub with variable gain

One more question. I have an RMA set up on the Head Unit. Is there a "best full android head unit" that i can buy and send this one back?

I want the unit with the best balance of being fast cpu (the one i have does lag a bit when trying to go in and out of apps and i am not used to that as i have always had decent android devices - it can be very frustrating), enough ram and 16gb storage minimum and also better sound quality than the one i have.

From what i gather they are all pretty similar in regard to the above but is there one out at the moment which stands out from the rest in terms of sound quality but keeps the full android and decent cpu?
[Android Head-Units] Hilari0:
Well, at the moment the best units around is the Intel Sofia based units with 2GB ram, they come with 32GB internal storage as well. I have the Joying JY-UL135N2 and I'm happy with it. As with all of the chinese Android head units, it has a few quirks, but it doesn't have any dealbreaking stuff. Plus it has fully working Bluetooth, just that they removed it from the Settings menu.. hehe. There's a thread here on the forum on how to make the full stock Bluetooth settings open, so that's really great!

Here's my head unit: https://www.carjoying.com/joying-ne...-wifi-mirror-link-entertainment-multimed.html

And here's the thread for full bluetooth: https://xdaforums.com/android-auto/...elopment/bluetooth-settings-launcher-t3504526

The biggest problem with it is that it doesn't have a good heatsink on it, so the CPU gets pretty hot. It still performs smoothly, so not a big issue but I don't like that it runs so hot so personally I'm gonna attach an Intel stock CPU cooler from a desktop with thermal epoxy, and that should take care of it.
[Android Head-Units] nk33:
ok great. I appreciate this

so just to clarify, with your stereo, there is no Bluetooth in the settings? So is there no way to pair your phone to make/receive calls unless i use this workaround? Why in the hell would they do that??

Also does this unit have usb flash ports so i can plug my 128gb flash drive in?

Also does it have sub-out?
[Android Head-Units] nk33:
EDIT

Actually i can see the sub -out.

It says bluetooth 4 on the site....if i only want to use the Bluetooth for making calls etc i am assuming i wont need to do the mod?

i use wifi tethering from my phone anyway - not Bluetooth - i am assuming this stereo will be ok with this.

damn this stereo looks good.

should i be worried about the heat? i am seriously thinking of buying this and getting them to fit it along with the other equipment...and send the other one back for a refund
[Android Head-Units] Hilari0:
The bluetooth works out of the box, but it's somewhat limited with their not so good bluetooth dialer app. It works to call and such, and limited pairing, but you only get full use of it if you do the mod mentioned in that thread. It's pretty easy to do that mod though. And yes, it has sub out but there's no built in crossover or anything.
[Android Head-Units] Hilari0:
Most likely it will work well despite the heat. In the worst case, would you be comfortable in opening it and installing a heatsink on it? Thermal epoxy seems to be the way to go there, Arctic Alumina Thermal Adhesive is the one I'm gonna use, just waiting for it to show up in the mail.

http://www.arcticsilver.com/arctic_alumina_thermal_adhesive.htm
[Android Head-Units] nk33:
Ok, I have ordered the head unit you have.

I will ask the fitter if he is willing to add a heatsink for me.

If it has an intel sofia processor… surely the processor has a heatsync gel and hearsink already?? It surely will overheat without one…?

Tell me are the audio specs better than my current unit? What is the rms on the speakers and the sub out voltage?
[Android Head-Units] Hilari0:
I have no idea what the output voltage is on the sub or preamp outputs, but the built in amp is 4x15-18W rms at 0,1 %thd. I can post a datasheet to the amplifier IC they use if you want. The sub output seems loud enough, I just use an active crossover on it with the gain set at 0 db.
[Android Head-Units] yurtesen:
[MENTION=4216853]Hilari0[/MENTION] I disagree that the sofia units are the best. Mainly because the whole chipset was a failure and development stopped and you will never get updates and never see android 6 even. So after 2 years it is garbage. Also MTK based quad core units are slightly faster and support Android 6, 4G/LTE etc. natively.

http://www.pcworld.com/article/3063...-tablet-markets-after-cutting-atom-chips.html

I myself bought an Ownice C500 after considering all the options. It was also cheaper and so far there does not seem to be any problems reported. The only downside is that it has 16GB storage, but well I am thinking I will stick in an SD card if it ever becomes a problem.

Also C500 units have a subwoofer out but I don't know if it completely satisfies the requirements of the OP. I just ordered a C500 unit myself and waiting for it :) although I won't use the subwoofer out.
[Android Head-Units] nk33:
Damn man. Wish you'd piped up earlier lol. What is the ram on your unit?
[Android Head-Units] nk33:
Thanks if you can post the data sheet I would appreciate it.

Also you didnt elaborate on the stock cooling? What does it use for cooling as stock?

Thanks
[Android Head-Units] Hilari0:
Development hasn't stopped on it, Rockchip is the one producing the Intel Sofia chips and will keep doing so and supporting it. Ownice has more cores, but single core performance is weaker than the Intel Sofia chips as it uses the Cortex A53 core. Intel is a better chip overall. Built in LTE depends on your needs. I will never get a second mobile data plan just for the car head unit, I simply tether it to my phone and get both internet connection and calling features from there. In some countries they allow twin SIM, that would be the only instance I'd make use of that. Where I live now, they don't even know what a "twin SIM" is..... Also, looking at the product page, it says the screen is a low res 800x480? Is that true? That alone would be a major deal breaker for me. http://www.ownice.com/Pro_Car DVD GPS for 2din universal_407.html

Android 6 is what it is, doesn't bring much to the table for these chinese head units. Most of the new stuff 6.0 brought was security features and enhancements, which the Chinese head unit manufacturers probably remove anyway..

The final nail in the proverbial "coffin" is that the Intel Sofia supports ultra low power mode, meaning that it basically shuts off when the unit goes into hibernation, when you switch off ignition. And it stays like that indefinitely and does not drain the car battery. This means that when you come back and start the engine, it instantly turns on and is ready within a couple of seconds. This alone is reason enough to go with that. Even if support for the Intel Sofia chips was dropped today (which it isn't), it's still perfectly usable for the next 2-3 years, at that time it's time to upgrade anyway regardless of what you buy today. All smart units will become dated at some point.

Presumeably that is it, but I haven't looked inside mine yet. Mine has a different front with the volume on top left, but the internals are supposed to be the same across all with only the front panel being different for the different units.
[Android Head-Units] nk33:
I was thinkong along the same lines about the development. Bottom line is it is a car stereo. Long as I can get most apps and the system suns smooth that is the main thing. The resolution was massive deal for me too.

Joying seem to be quite responsive via email as well which is a nice touch
