[Samsung Galaxy Tab A series Questions & Answers] blackhawk:
You're welcome.

It's safe to put it in sunlight just not with LCD facing it. As long as it's cool enough to touch it won't harm it.

Most at risk are the powerc circuits carrying higher current loads which can accelerate corrosion damage. Or it may simply keep the signal tranfer on data circuits from working with no damage. The faster you pull the battery then dry it, generally the better the outcome.

I dropped my Galaxy Buds case in a cup of coffee (cream&sugar🤣) over 3 years ago. Open it immediately, flushed with RO water, then anhydrous isopropyl alcohol, dried for a day, then drank the coffee. It still works today.

Hi!

I got an Audi A3 8P from 2010 and installed this HU. Everything is working, Android auto / radio / GPS / canbus / OBD, the "only" problem is the audio quality is horrendous. I was expecting it to be worst than the concert radio but it is really bad to the point I'm thinking about returning the head unit. I want to try to improve it before returning it because I was in a friend's car with the same head unit and the sound quality was miles away. I'm pretty sure the problem is hardware/connections. I read somewhere that some Audis have rear speakers amplified and front speakers not amplified. I'm not sure if my car has this configuration but that can be related to the problem.

What is happening is that the sound feels like someone is pushing the gain to the extreme. High/mid frequencies are very uncomfortable and the low frequencies are almost non-existent. I feel like the 3 speakers from the front are being pushed hard and the 2 front door speakers are very low. I saw a video (in Russian with awful translation so could not get much out of it) where the guy was saying that the TDA 7851 amplifier chip usually has too much power for factory speakers (he was not talking about Audi in particular). I spoke to Junsun and they told me they would look into it and try to find the solution but in the meanwhile, I asked for more specs. If I cannot find a solution I will return the hu.

I leave here some technical specs to see if anyone in this forum is able to help me. If I find a solution where I have to replace some speakers or get an amplifier I don't mind. I was thinking if it is possible to get a non-amplified output from the head unit and connect it to an amplifier that distributes for the other speakers.

Audi A3 8P

5 speakers in front and 2 speakers in the back

year: 2010

Head Unit: Junsun V1 pro (I will not post a link because I'm not sure it is allowed)

8-core / 4GB / 64GB

Radio chip: ST7708

Amplifier chip from the head unit: TDA 7851

DSP / RDS: Yes

Android 10

outputs: 4*45w

I found the first picture online but the interior is the same. I also leave here the wiring diagram, according to Junsun I just have to connect the main bay and then 2 RCA's for the rear speakers and 2 RCA's for the auxiliary input.

Thanks a lot for your time
[Android Head-Units] Dema323:
I have the exact same symptoms in my audi tt mk2. As i had no experience with the oem radio i just assumed it was the car that had bad sound and bought an under seat subwoofer.
[Android Head-Units] xpc0391:
Thanks for leaving your input.

Did the subwoofer solve the problem? I want to test with another speakers to see how the sound comes out of the junsun head unit. Also I will try to take the car to a friend who is able to measure what is coming out of the unit channels. I will report back.
[Android Head-Units] Dema323:
The subwoofer addes base, which made the sound good. But would not call it excellent, just good enough that it doesn't bother me.
[Android Head-Units] Kwen:
Maybe try the DSP and play with the subwoofer low pass frequency adjustment, it may be filtering out the low frequency to send to a non-existing subwoofer.
[Touch HD General] pitchbend:
Just received my Touch HD today and had to realize that when you plugin a normal set of headphones, the telephone gets into headset mode and the its built in microphone doesnt work any more until you plug the headphones out.

is there any way to avoid this?
[Touch HD General] Acelister:
I wouldn't imagine so... It's a feature where it knows something's in the headset socket, so it deactivates the mic...

[Samsung Galaxy Z Fold3] pvillasuso:
First !!! :cool:

Totally recommended with lots of features !
[Samsung Galaxy Z Fold3] dr.ketan:
Dear friends

I have consider to make this ROM as there is no active development on Fold3 and everyone should thank to @pvillasuso for pushing me lol! ROM made within couple of hrs and that without having device so may some bugs expcted, but according testers, stable enough for release.

Also thanks to all testers who have tested and reported. I may not be able to release ROM with every new firmware but will try my best when time permits.

Again thank you all for showing love & trust for Dr.Ketan ROM
[Samsung Galaxy Z Fold3] chris92500:
Hi,

Perfect Rom!!! thank you Dr.Ketan to provide us with this rom :)
[Samsung Galaxy Z Fold3] f4bio:
works like a charm! great work doc!
[Samsung Galaxy Z Fold3] Sinus1:
Installed your ROM, and finally my Fold3 is happy :-) Thank you Dr.Ketan for your excellent work!
[Samsung Galaxy Z Fold3] junevtec:
will we ever see this rom for the usa version ther sm-f926u??
[Samsung Galaxy Z Fold3] dr.ketan:
Important :

ROM S01 reported working on base F926BXXS1CVCA April scurity patch too, so you can first update to new base - Root - Install ROM (follow installation guid above)

.
[Samsung Galaxy Z Fold3] pvillasuso:
Not possible , this is just for the F926B variant only .

AFAIK for several reasons, such as rooting and unlocking bootloader not available for for sm-f926u
[Samsung Galaxy Z Fold3] klemen241:
It says installed, but there is no ROM Tool app
[Samsung Galaxy Z Fold3] dr.ketan:
Show me magisk module page screenshot
[Samsung Galaxy Z Fold3] klemen241:
can be a problem that i am on march security update?
[Samsung Galaxy Z Fold3] dr.ketan:
If you are on non supported firmware then module itself have turnd off (Check module page) to prevent bootloop. Read installation guide and changelog post and follow it to the letter.
[Samsung Galaxy Z Fold3] klemen241:
That must be it. I will update official firmware and try again. thanks

ps: rom works great. For now no problems. Only in the battery bar addon, has ON and OFF switched haha.
[Samsung Galaxy Z Fold3] mcn1970:
Thanks for the ROM.

Is Samsung Health and Galaxy Watch pairing working properly?
[Samsung Galaxy Z Fold3] pvillasuso:
Yes , both working properly

Hello master! @dr.ketan

This custom ROM will work on F916B (Z Fold 2) . Fold2 not have custom ROM's.. Can you suggest me if can give a try with your ROM on this phone Fold2?
[Samsung Galaxy Z Fold3] bogdanwiki:
@dr.ketan can reply , please? I need your advice urgently !

I really appreciate your work and want to use this release of your ROM 😜
[Samsung Galaxy Z Fold3] mcn1970:
Definitely this ROM is not for Fold2. Otherwise you would find it in Z Fold2 threads.
[Samsung Galaxy Z Fold3] loizos250:
i have been following dr ketan for years and his work is amazing. i am also interested for z fold2 rom if its possible
[Samsung Galaxy Z Fold3] dr.ketan:
I dont own any fold device. Only Fold2 users can try and confirm, If it won't work, mostly ROM won't load. (You can see ROM module disabled in Magisk). What maximum can happen is bootloop, which can be fix by factory reset. Now it's your turn to test and let us know.
[Samsung Galaxy Z Fold3] loizos250:
@bogdanwiki i will let u try first :)
[Samsung Galaxy Z Fold3] bogdanwiki:
I will give a try tonight ! Maybe will work :cowboy::cool:
[Samsung Galaxy Z Fold3] loizos250:
keep me updated
[Samsung Galaxy Z Fold3] loizos250:
any news my friend?
[Samsung Galaxy Z Fold3] shatteredsight:
Hi @dr.ketan,

I'm still on F926BXXU1BVA9 from exocetdj's 420Rom, do I have to start from scratch

to install your ROM or is there a chance that it would work on top of this?

The phone is rooted with Magisk but without Zygisk.

Thanks
[Samsung Galaxy Z Fold3] pvillasuso:
Prerequisite :

Must have installed firmware F926BXXU1CVC5 (Reported working on F926BXXS1CVCA April scurity patch too)

Rooted device with Magisk (Zygisk) Intallled (Follow steps below in case you have non rooted device)

We recommend to make EFS (IMEI) backup as soon you root device and keep copy to safer place (outside device)
[Samsung Galaxy Z Fold3] klemen241:
from scratch. I tried directly from 420 and got bootloop haha
[Samsung Galaxy Z Fold3] jhr5474:
I have cvca and I downloaded your Rom tool but it keeps giving mismatched md5, any ideas?

I had the xxs instead of xxu firmware, when I switched to the xxu it still had issues until the next day when suddenly it let me install. Hoping to see updates to this, of testers are needed I am here .
[Samsung Galaxy Z Fold3] Duck4Cover:
Did you give this a try? Would be good to know if you have already attempted.
[Samsung Galaxy Z Fold3] verplanloster:
yeah rom is very good. thanks doc. but nfc paymend dont work. is there any patch?
[Samsung Galaxy Z Fold3] loizos250:
did u try it on fold 2?
[Samsung Galaxy Z Fold3] verplanloster:
Fold 2?
[Samsung Galaxy Z Fold3] little-endian:
Maybe you could add a link to your guide as the question arises "with what?". Since you button labelled "GET IMEI BACKUP RESTORE TOOL" unfortunately seems to link back to the main page on your website, I've tried that "EFS Professional" tool, which however fails already with a rather old Note 8 (array of the first dimension - "aha"), letting it appear questionable that it would with even newer devices such as a Fold3.

Some other guides in terms of EFS backups seem rather outdated and for example refer to copy some /dev/block/mmcblk0p3 which already doesn't exist on a Note 8 (F3 yet to check) so it can't be a generic step to follow either.
[Samsung Galaxy Z Fold3] dr.ketan:
My Tool doesn't support Fold 3 unfortunately so kindly look for other possible way, nor I have Fold3 to help you better. In case you have TWRP this may have this option, just check it out.
[Samsung Galaxy Z Fold3] Bryanpen77:
Hi all. The worst has happened to me. Lost EFS and my computer died with the backup. I got a new one, unrooted back to stock but IMEI is 0 and no EFS. I am really in a bind. Can someone send me a copy of their EFS backup? I my fold is functional again but EFS and IMEI is gone. Only had my fold a few months
[Samsung Galaxy Z Fold3] little-endian:
Sounds like Murphy's law at its best. Don't say that Dr. Ketan's ROM caused this. ;)

So how exactly and at what step did you lose or corrupt that partition?

While I (hopefully) backed up mine, it is questionable to be of any use as the question arises how you'd edit it to make the proper adjustments to match your phone. After all, data such as IMEI & Co. is specific to the exemplar you have and thus cannot simply copied without risking to provoke conflicts on the network / operator side.
[Samsung Galaxy Z Fold3] Bryanpen77:
Was coming from 420 rom. Went to reflash TWRP doing a total format and wipe to boot into rom and I noticed that I didn't have signal. Lol and behold my IMEI showed 0 couldn't get back into TWRP, it just kept restarting back into system. I flashed back to stock and still 0. My laptop finally gave out as it is 11 years old. I lost 2 backups along with everything else. My box doesn't have the full IMEI because it was partially torn . At this point I am willing to try anything to get my phone signal again. Damn I hate this happened. Lol and no I don't blame the rom. I am really in a bind though.
[Samsung Galaxy Z Fold3] mcn1970:
sorry for noob questions. is secure folder working? galaxy watch 4 can be paired? thx
[Samsung Galaxy Z Fold3] pvillasuso:
Yes
[Samsung Galaxy Z Fold3] Techvir:
Don't know if already solved it.

But here is a suggestions. You may have corrupted the permissions of the efs folder. You need to correct them. Then Odin flash the default Rom. This should work.
[Samsung Galaxy Z Fold3] christis:
The laptop died, but is the hard disk operational? As your LAST resort, You can remove it, and with the help of a usb adaptor you can connect it to your new laptop as external HDD, then recover the backups you made. Beware, the USB adaptor has to match the old HDD interface (SATA, PATA, etc)

[OnePlus 9 Pro] ali_12am:
Can I change the model of my phone in Android 11? Now I have LE2120 that I want to change to LE2123. Is something similar possible
[OnePlus 9 Pro] djsubterrain:
You can name your phone anything you want in build.prop (as long as you're rooted) but why? Doesn't change it's hardware or capabilities and if you flash incompatible firmware you'll likely brick it.
[OnePlus 9 Pro] TheKnux:
Here you go. Flash in Magisk.
[OnePlus 9 Pro] ali_12am:
I am now on Android 11. My phone model is also LE2120. For some reason, I had to change my imei. When I want to update to Android 12, the original imei are reset.

I heard that imei in LE2123 models do not disappear when they are updated to Android 12 and remain the same, that's why I wanted to change the phone model
[OnePlus 9 Pro] ali_12am:
Any Ida?
[OnePlus 9 Pro] TheKnux:
Your IMEI is always the same no matter what unless you swap your main/motherboard.
[OnePlus 9 Pro] ali_12am:
Any ida?pls
[OnePlus 9 Pro] TheKnux:
Bro, I literally linked a magisk module that does EXACTLY what you're trying to do. Flash it in magisk and stop asking for help on here when it has been given to you.
[OnePlus 9 Pro] ali_12am:
Yes i did with magick,but when i go to update i got LE2121 update,not LE2123 🤔
[OnePlus 9 Pro] TheKnux:
LOL it doesn't make you get updates for that model number. You have to flash the corresponding firmware for that.
[OnePlus 9 Pro] Arcide:
Since this is being talked about, and I couldn't find an answer... I have an LE2120 model, and I'm on 11.2.10.10.LE15DA firmware (Indian?), but I live in Europe. How would I switch to EU version and is there any point in doing so?

On an unrelated note, I'm using joneplus tools to enable recording in the oneplus phone app (which I downloaded manually), but it's unreliable. It records incoming calls 99% of the time (with some rare exceptions), but it doesn't record outgoing calls if I'm holding the phone to the ear (and the screen is off) at the moment the recepient answers. Could this be related to the software version? I've never seen someone else with this issue.
[OnePlus 9 Pro] TheKnux:
If you didn't use the Indian OnePlus9 (non pro) msm, I believe you can use either an EU msm or an EU fastboot stock rom. I have a proper flashall file on my pc that properly formats the partitions correctly. There's really no point other than updates. I chose DA cause they have the most feature-packed (or useless) ROM and they seem to get updates faster than EU sometimes.

Try this. Make sure you fully set it up through the app settings. I'll send screenshots of my settings if needed.
[OnePlus 9 Pro] Arcide:
Alright then I guess it isn't worth it then.

As for the call recording app, thanks for the suggestion. I've installed it and hopefully it doesn't betray me when most necessary. I don't like having the constant notification on so I've disabled it, but I've disabled battery optimization and locked it in recents. I'm hoping that's enough for it to always work properly.
[OnePlus 9 Pro] TheKnux:
@Arcide Wait, you're doing all of that for the current call recorder you're using? Or for the one I told you to try out? Because the one I use, with all of my settings, works every single time. I even have it setup to auto upload and delete starred recordings. It has a ton of options and it does what I need it to do, works for both parties and it covers my butt cause Ohio is a one party state. 😎
[OnePlus 9 Pro] Arcide:
This was posted before I got your answer I believe :D

But no, it isn't just because of the call recorder, I was just wondering in general it there are any benefits to match the software with my region.
[OnePlus 9 Pro] shafck:
Boşa uğraşma kardeşim. LE2123 ROM'u da yüklesen, eğer cihazın orijinali Çin ise (LE2120) IMEI Android 12 ile orijinale dönüyor. Denendi yani. Cihazın gerçekten Avrupa modeli olması lazım. 2120 ile şu an için Oxygen OS 12 kullanman mümkün değil imei değişmesini istemiyorsan. İlla Android 12 kullanmwk istiyorsan, 11 üzerine custom rom kurabilirsin. O zaman etkilenmiyor.

[OnePlus 9 Pro] TheKnux:
Gotcha, I figured lol. Feel free to PM me if you'd like or hit me up on TG. Same username/icon. Not really any benefits. Just as long as your modem is up to date, you should be good. I definitely recommend BA over AA though,mainly cause AA is incremental and hosted from Google's servers so you can't extract the images from the payload.bin file.
[ASUS ZenFone 8] DerSteppo:
Hi, I dropped my phone by accident and unfortunately, it fell on the volume key which is now bend in the middle and stuck pushing vol up. :cautious:

I can push volume down but the key is stuck with volume up and the phone would do that at random. For example, at some point during a call it would go to maximum volume automatically, which is super annoying.

Does anyone have experience with replacing hardware parts of the Zenfone 8? I watched this tear down video , it looks kind of easy to disassemble. However I am not sure if I can reach the volume key without removing the main board. Also, not sure if will be water proof after reassembling (guess not, but no problem).

Any tips? Thanks everyone!
[ASUS ZenFone 8] Adaoh:
I tried searching a bit but couldn't find any Zenfone 8 buttons (though maybe buttons from other phones could work). What I found instead is a complete frame that does come with the buttons attached to it, so you could either transfer the whole phone internals to it, or try removing the button to put inside your original casing. (I think the second option would be easier since the battery is glued down pretty solidly)

Anyways, here is the link: https://www.aliexpress.com/item/1005003661617745.html

I think it will not be water proof after you open it, so you should also consider getting a new seal. (Consider that I have never openned my zf8 lol so I am not pro). But from what it looks like, it will most likely be easier and safer for the board to remove it before playing on the side and risking slipping and scratching the pcb

EDIT: I found the specific volume key on asus-accessories.com for 12$!!
[ASUS ZenFone 8] DerSteppo:
Thanks for your help! I already found and ordered the spare part on https://www.fixshop-online.de/ I hope that 24 Euros are not wasted. 😅

Hopefully, the whole open and repair process will not be too difficult.
[ASUS ZenFone 8] amenthes:
I would be very interested in the results. Most importantly, if the spare part is a good quality replacement. Also I would be interested in how easy or hard such a replacement is. I looked into many of the teardown videos before buying the device, but those are usually from super-experienced pros with all the fancy tools. I would be interested in a first-hand report, even if it's short.
[ASUS ZenFone 8] DerSteppo:
I will keep you updated. A friend sent some special adhesive tape but it hasn't arrived, so I didn't start disassembling.

The spare part, however, seems to be not available. I received an email that they don't have it. So I wait a little, maybe they can order it, but if it will not arrive end of April, I will just try to fix the bent old one.
