[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] [HELP] I can't turn on my 1+1 (no fastboot, adb, just 1 vibrate)

Hi guys,
I have flashed latest firmware for cm12 by boeffla (23rd JANUARY) on cm11s (because kernel doesn't work without it) and there was bugged one thing ... For now you will facepalm yourself a lot. I was disappointed from the bugged logo which i wanted to fix by flashing logo from 44S. I thought that this flash will solve that, but the reality is bad, i have bricked it (phone just vibrate on start, no fastboot/adb). I read about this and the only way to fix it (I think, thread "?is saying that?") is JTAG.
Can I fix it only with JTAG (I hope that the way is real) or is there other way to solve this ? (I know, I have bricked it for stupid reason, I am beginner and sorry for my bad english.).
Thanks

I have the same problem as you. My OPO will not show anything on the screen, when I hold the power button I get one vibrate and that is it! Where you able to recover? I am very very interested in knowing? If so, I have looked at the guide up and down and I cannot understand the guide that was posted, It seems that the program MSM8764 tool does not work or does not like me. I look forward to your reply. Thank you greatly.

Your computer must recognize OPO as QHSUSB_BULK or Qualcomm HS-USB QDLoader 9008 (try to turn it on/off a lot of times by clicking volup and power (10s) until your PC will recognize it) then you need to install drivers from Color.zip (It is in drivers.iso, extract it, auto installation is chinese (I had to disable driver signature enforcement on win 8.1.)) and you will be able to run chinese utility which will flash ColorOS. I did it like this and my OPO is fully working.

Help on Xperia Z3 Right channel/Bottom speaker extremely low volume

Hi, can someone please help me
I rooted my phone like 2 weeks ago, the sounds were perfectly fine until I noticed that it became lower yesterday.
I don't know what happened. It was not dropped nor got wet. The volume suddenly became lower
I think it's the lower speaker.
It's fine when I use my earphones. I also tried to max all the volume thingy in settings.
Can someone help me to fix it?

UPDATED: I've been trying to figure out my phone's problem for the past weeks. I even started a thread about it [you can find it here].
I found out that the problem is the right channel or the bottom speaker.
I've been looking around and found out that some experienced the same.. No one said anything about solutions and what not.
Anyone here experiencing the same problem? If yes, did you do anything to be able to fix it?
I tried factory reset and flashing my phone. Nothing friggin happen.
I wanna know if I could resolve it on my own before I send it to the shop for service >.< (which is friggin far from me).

Hmm.. I can only advice few things.. But you should backup your stuff and have long process.
1. Factory reset as first measure.
2. Use PCC to repair your phone
3. Flash other firmware
If it is software it will sort our by this, if it is hardware, then mate you need to send it to Sony center.

Upp with updated query!

oneplus one stuck at bootloop when not charging

HI I have 1+1 and its 2 years 3 month old. Presently its on CM13 MM(oxygen OS I guess) and rooted and have a recovery also. I did root and recovery around 8 months back.
2 days back when mobile was in pocket and 35% battery it went in to bootloop. after lot of stuffs like clearing cache and dalvik cache nothing worked.
Later at night i found out that mobile is working fine when its connected to charging (either by lapi or Mob charger). Hence I didn't go back to old recovery.
yesterday fully drained my battery and later charged to full and found same issue.
I am not able to make out whats the issue and how to move forward if I don't want to loose my resent data state. PLs guys help me to solve this issue.
will do whatever needed to restore my mobile. TIA

Wait I didn't understand what u said ,ur saying that your phone gets stuck in boot loop when its not charging ,what happens when you are changing and then u plug it off ? Does it like reset ?

see it sounds weird but its true. when i connect charging it boots in normally and normal operation will start as usual. Even after full starting, once I remove charging connection it goes off to boot loop. I didn't do any modification in software also. just did normal downloading off apps.
I saw slimier 2 complaints in Oneplus forum but no one relied for that. even originator has not updated what he did finally. I have asked for reply from them too.

Then no issues with hardware....seems like a bad/corrupt frimware.
You need to unlock your bootloader and flash latest Cos13 through fastboot.
How to- https://forums.oneplus.net/threads/...oader-install-custom-recovery-and-root.64487/
To flash Cos13- https://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
Hope this helps.
Edit:After reading your first post seems like you're already rooted and have Twrp installed,with a unlocked bootloader,obviously.Though I don't able to understand if you're using cm13 or cos13 or oxygen os...
If you don't want to loose your internal storage,you can skip the userdata flash command while flashing Cos13 through fastboot,though,it is recommended to do that command.
You can always go to Twrp and take the backup of your internal storage in pc through MTP or a full backup using ADB.

bro one more issue started yesterday. I thought to making battery full nil and charge to 100% may help.
Before without charging connected I was able to go in twrp but not now. if i remove charging its going to restart even recovery mode also. When I went to restore old backup in TWRP mobile is auto starting even when charger is connected. but if i dont do anything its staying fine in TWRP lock screen.
without charging connected i can go into fastboot n stay for as long as i want but comp is not detecting mobile even though developer option is ON.
Yesterday thought of restoring old backup which interrupted half within 1min and now if i start mobile while charging its getting struk at 1+1 welcome screen.
I am fully confused like anything..

is it not strange that so many people (including) have started facing this issue suddenly in the past two months?

I too am facing this issue. Has anyone managed to find a fix for the issue?

But the sad truth is we can't get any original / as good as original replacement. Oneplus stopped production 2years ago. I did a quick google search and found out most of the batteries are ****. As you're name suggests, I think you're from India. Can you please inform me if you find any decent batteries? I will inform you if I find anything good.

yes I am from India. I would suggest you first try with replacement battery as everyone sell replacement battery. you can find any of these in ebay. In India Oneplus is ready to arrange a original one costing Rs 1800. They asked me for a week time to arrange original battery. So its upto u to decide to take new one or replacement.

Me too having the same issue. Seems like OnePlus one devices have some kind of kill switch to ruin it after 2.5 years. Quite a few number of people seems to have this issue all of a sudden.

No sound at ALL on my OP6

Greetings, everyone. So I got an OP6 a few days ago from someone I know and it has two problems - first one is that there is no sound at all from the phone, the speakers, the headphone jack, even audio through bluetooth don't work (when trying to play audio through bluetooth the phone starts lagging like hell). Second is, the fingerprint reader doesn't work too, there is no option in the system, only on the first setup screen (after a reset) where it doesn't work anyway.
The guy said it happened after an update. I tried re-flashing it many times because it kinda looks like like a software issue, but nothing help. Diffrent roms, stock or not, doesn't matter, tried unbrick tool, no luck aswell. Disassembled the phone in the end to check for water damage or loose cables, but even that didn't help, everything seems normal inside. And it's pretty wierd to have 2 separate things not working at all.
There is no official support for Oneplus in my country, the phone is imported so getting an official repair is not an option. Anyone got any idea what I should be looking into?
Thanks.

Well.. we had people that didn't try it...so no point in thinking and skipping questions...

have you tried to reflash the whole stock rom with using fastboot images ?
I've got that problem too before, it's becaused I flash a stereo sound mod, and updating the software. and I lost all of my sounds.

Interesting, did you not have any sound at all too? From the speakers as well as headphone jack?
But yes, I tried to flash from fastboot, even did the unbrick tool which seems like the best method to get a complete factory reset. I'm not sure if there's some part of the firmware that can still be corrupted even after flashing though the tool.

Thanks, I'll try again later just to make sure.

Sadly, didn't work again. Flashed all the partitions that can be flashed with that tool, but still got no sounds, so probably it's a hardware issue in the end, but it's hard to imagine what exactly is broken.
