[Q] downgrade to stock rom from 10.1 (this is not simple)

Hi there
My phone needs to be sent to samsung service to be repaired and it is still covered by the warranty
Obviously before send it I have to revert to a stock rom (one samsung original firmware), but this is not so simple.
Scenario:
1) I am on 10.1 A8
2) I am unable to connect my phone to any computer via USB (hardware issue or rom related???)
3) mobile odin not works with CM and MIUI based rom (due their particular file sistem)
4) because of the different file system I cannot simply use the recovery to flash over cm 10.1A8 a not miui or CM rom (i.e. Frankenstain mod) and then use mobile odin to flash a stock firmware
so I am here trying to find a solution and any suggestion will be really appreciated .
thx
cheers!

What are you saying odin not works? Its not true. Follow my guide in this section entitled "General guide for noobies" there's a guide on how to return to stock.

thank you for your kind answer but that's it.
Odin do not detect the USB com port where my phone is connect and even the computer do not recognize my phone. It is not a driver releted issue (I tried on athor computer and always installed latest sansung mobile usb driver and even latest adb driver)... I guess it is hardware related.
So the question is:
Starting from cm10.1 A8
1) can I inject via cwm a stock rom? (I suspect the answer is "NO")
or
2) there is any injectable rom that is compatible with MOBILE odin? (not CM or MIUI based)?
thx

Hmn thats a problem. You just flash stock rom with Mobile Odin. You tried installing KIES? before doing odin?

yes, I guess it is hardware related... yesterday I bought a new S3mini (which I have already rooted and injected CM10.1 by maclaw and it is fully working except for some minor issues) eheh
I am trying to repair my slc (hoping that it is a problem related to minor device and not the whole matherboard)
but also
eheh cheers!

just to share updates of my phone's problem:
During a call (and only during a call and not all the time) my speakers starts rustling and it stops only when I push or knock on the backpanel near the sim and sd card.
After that I can continue my call... but in a short time my phone freezes.
I guess that is the cause of reboots or SODs. In the last past hours I also notice that After a SOD it didn't boot at all with strange stripes on bootlogo. Even this time pushing an knocking on the back help to make my device boot.
So, tired of this situation and unable to restore original fw to send it to sammy service (I am still under warranty), yesterday I decided bought a new phone (S3mini) and trying to rapair by myself my slc.
That's all.
For me this thread (if is not usefull for other users) could be closed.
Thank you all!
cheers

[Q] Problem with touchscreen after unrooting

Hello guys,
So... I have samsung GT-S7710 (Galaxy Xcover2).
I had it rooted with prerooted odexed FW (from this post)
So this is the OK part :laugh: .... everything was working fine.
Then, to claim my waranty, i have unrooted it...so I've reseted the counter and flashed it with FW I've backed up from my phone before rooting.
So now for the wierd part...everything was ok, booted my phone, everything was working, then restarted it, and all of the sudden touchscreen stoped working
I've read about bricked touchscreens, but mine worked for some time..
So I was thinking now...should I try and flash official FW for my phone, rather than backed up one ?
Or is there any thing else to do ? Or even...did maybe touchscreen went to *khm* ?
Thank you guys for your time you spent reading & hopefully anwsering this

Thanks for your reply, I've tried this right away.
I've tried with official version (from SamMobile)...I've choosen version for Slvoenia (my country) w/o any provider
But still no sucsess...
Odin sucsesfully flashes, phone boots, and touch doesnt work again (I'm stuck at that starting page...to chose language and so on..)
But like I've said everything else works ok, eg.: power btn, wolume up/down,... only touch doesnt work.

Sorry for the double post..
I've tried to flash ROM that I was using before (rooted one). And now touch even doesnt work in this one.
Is this maybe hardware problem ?

i think you should flash stock rom and give it to samsung maybe.. if it's in warrentee they would get it replaced i guess
hope it helps you

I will do exactly this
One more thing... I've bought my phone in a electronic store (no carier involved). Should I flash it with FW for my country ? What if phone had any other FW on when it was new ?
EDIT:
Just realised....I've flashed rooted FW on my phone...which has increased the counter of custom flashes... To reset the counter I need root permisions...but how if I cant even unlock my phone.
I probably cant use [email protected], because I've hard reseted the phone, which means that Usb debug is disabled (correct me if I'm wrong), so thats of the list..
Do you guys know if any FW has enabled USB debug by default ? Or if there is any other option ?

Flashed wrong recovery, TOUCHSCREEN IS FLIPPEd

Hello, i have a Samsung Galaxy S6 U.S. Cellular. Sm 920R4 i believe. Anyways, i was trying to flash TWRP Recovery. When after i did, my device rebooted and took me to the TWRP recovery screen. Expected. But my Touchscreen wouldnt work. So this happened 2 days ago but im still trying to fix it. i decided to try some different versions of TWRP. Well, one of them worked but it reversed my touchscreen. So i managed to get into my os, BACKWARDS. I have been using everything backwards including the keyboard and its driving me nuts. I attempted to flash my stock recovery and stock firmware via odin. Odin says "failed" every tiume i try to flash it, so i moved the zip to my s6, and it still doesn't work. if fails. I dont know what to do. Someone, anyone, please help me. I recently tried flashing a rom and it turned out to be the rom that makes the s6 look like the s6 edge plus. Well, i didnt copy down my imei or serial number before doing it. So i cant use smart switch. I really need someone to just help me out. Even if its just a tweak or something to flip the screen back to normal. Someone please help me. BTW, the secret codes havent worked for me to update the screen. Maybe im doing something wrong, but at the moment the phone doesnt have service

This might not work If you have modified rom, or you will waste a lot of time reverting to stock and back.
Just try flashing a different kernel. I had the same problem and it worked for me.

I have a Custom ROM and it worked for me. Just flashing another Kernel didn't work for many users who tried that and this (on my link) worked for everybody.

Sam-g920r4
do not tell me where you can take the firmware service (4 files and PIT) for G920R4

Details
What Kernel? and the special codes DO NOT work with the phone at all. Im freaking out. Haven't fixed it. Please reply. Thank you.

How do you mean that they don't work? Nothing happen when you dial them? Do you have custom ROM or did you unabled or uninstall any of the sistem apps?

How about the twrp app. If you have root access you can change the version of twrp

Did you try reflash the firmware via Smart Switch?

So I flashed a rom-upgrade type thing that makes the phone look like an s6 edge plus
If i had my imei i would be fine but i dont have it
The codes dont work, typed and retyped them a million times
What rom could i flash to have access to the codes, and what kernel to fix the x axis did you flash? a quick reply would help a lot. Thanks for your time. I do appreciate a lot. And yes ive tried smart swith and odin with stock firmware. It fails. I only have one file that i was flashing though. Maybe there was more.

Acer iconia A1-830 touchscreen not working after flash

so about a month ago i had my iconia rooted and somehow it got soft bricked (i cant remember how) and ive been trying to reflash to fix it. after a couple weeks i was finally able to make some progress and get it to boot up all the way to the language select BUT the touch screen doesnt work anymore so im stuck again. i know its a software issue because the thing is practically new. doesnt even have a scratch on it and ive been storing it in the original box when i didnt have time to work on it.
Rom i flashed is : Acer_AV052_A1-830_1.014.00_WW_GEN1_FLASHPKG.7z
if more information is needed i can see if i can access it somehow. If anyone knows about something i can try to fix it using fastboot or adb it would be much appreciated. ive tried all the post about soft bricks and the screen not working for this device but unfortunately it isnt that popular so there arent many threads on it.
thanks

No one has any ideas?

How to update an outdated bootloader J710fn?

Hello,
I have two j7 2016 fn. One is mine one for repair. I recognized that there is a bootlogo difference. The onw which works has a thin powered by android line while the one with touch problems has a bold android. So I guess there I have an outdated bootloader on that phone. How can I update?

Yes I already tried
But smartswitch said that the phone does not allow data transfer via usb.
I can't use touch. Every rom I flashed does not make the touchscreen work.
I saw on youtube that some said to get back to marshmallow. But I heard that could lead to loosing the imei.
What should I do?
