Hey folks. My phone is a Verizon galaxy 8 note. I noticed in the note 8 forums me2151 posted that there is a non rooted rom with xposed. He said it has some glitches but if we want to learn more to look in the s8/s8+ forums. He said it is compatible with note 8.

Is this the rom he was talking about or is it the one by jrkruse?

Thank you friends

Man don't waste your time I've been almost 2 months trying to find someone to give me any information about my n950w Canadian custom rom

No one answers or at least no one car for us note users

I tried everything every single thing that you can imagine nothing works

The admin here doesn't answer anymore

My budget is very very tight but now I'm thinking about a way to buy the exinos version JUST to install the grx touchwiz which needs root for unknown reasons

Goodluck bro

when i go to flash CSC, it says "FAIL! Model dismatch fail", any idea why it would this? my phone is the SM-G950U of the Snapdragon variant so it should work no?

hi

i have a big question about this modded system do i have to be rooted on my s8 plus snapdragon to install this or can i do it from a regular stock s8 plus?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] bradical711:
You can do it from either or but what really matters is your BL revision number. I believe if it is higher than 2, then this ROM will fail to flash for you. Also this isn't rooted due to it being Oreo and isn't anything really big in terms of a custom ROM. Just like the description says, it's "Pixel'ish"..

I have a question regarding recompiling systemui. I can flash a deodexed systemui but when I DECOMPILE and recompile after replacing .9.png. my screen is black but I can see icons. But there is no lockscreen or notification panel. I even replaced the res,Dex files, and resources from the original systemui. But nada. Black screen,icons and no lockscreen. Yash (who created the Oreo guides thread for touchwiz) told me that I have to disable signature check, that means i have to deodex services.jar and recompile it. I thought that I couldn't deodex services.jar because you can't deodex firmware files otherwise I'll end up in a bootloop. Can you clarify how you made the systemui mods work. Mods such as fingerprint after reboot and other stuff......
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] austin_5118:
I read through the whole thread, and didn't see anything like this answered already so I'll go ahead and post. Is there any hope of doing this to a snapdragon s9? (SM-G960W) ?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] bradical711:
No. This is for the S8 (SM-G950U) and S8+ (SM-G955U) ONLY. Flashing this will result in soft brick for your device I think, or worse.. It is not compatible and will not be compatible.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Magnusmarshall:
They wont respond because its painfully clear you didn't bother to do any searching at all.

A simple google search for n950w custom roms literately shows links to this site with the answers you want.

Its a big no no on this forum that you come asking questions and expecting answers without doing any homework on your own.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] SamerAlHaddad:
Oh man you're so old....... :):):):):) this message is old before the root methods, and yes i did my researches, i was combining my days with nights, barely sleeping and drinking 4 redbulls a day and almost seeing the phone in my nightmares, i googled every single thing you can imagine that time, i learned some basics just to create my own rom, i went into a state of depression JUST because of it and you're telling me that i did'nt bother to do any searching at all??????? OMG

anyway, i ended up selling my snapdragon note 8, bought an international version FDS, created my own CSC for canada to enable some options i needed, and living happily...

oh how life is funny sometimes....
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Magnusmarshall:
Well i am certainly not 21 anymore. ;)

But unfortunately this very response should how little you actually did or how bad you are at it.

I kid you not it takes less then five min to find the answer your question and that answer has been here since before you made the post.

This is hammered into place by the fact root actually existed for about a year before you got the phone or at least posted your question.

If you didn't realize those very obvious facts you didn't search very hard.

Still i am happy your happy now and lets have the thread go back to what it should be.

[MTCD Hardware Development] scorillo_ro:
Nice work @marchnz !

A full step by step and pictures howto should be made now and all those PX5 users without sdcard slots will be able to use this method to get Android8!

LE. I drew a schema
[MTCD Hardware Development] lucajust:
So with this methon, will be possible to flash on 6.0 unity, the recovery and the system of android 8.0?
[MTCD Hardware Development] marchnz:
Absolutely! I've done it a bunch of times. You can either use the sdupdate.img from the Oreo upgrade thread to load the Oreo recovery and then install the oreo .zip from recovery OR a full set of partition images.

I have a full set of partition images if needed, they're about 25gb but should compress right down (that 25gb includes [user] partition which is an empty partition.
[MTCD Hardware Development] lucajust:
Good... I'll try... But the process Need a PC no? Becouse with the unit with SD card slot needs PC only to prepare the sd card for android 8 recovery

Inviato dal mio Mi A1 utilizzando Tapatalk
[MTCD Hardware Development] marchnz:
Yes, PC. I've updated the post to include links to tools and driver. Driver 4.5 & Android tool works on Win7 - Win 10, x86 and x64.

For those without SDCard wanting to upgrade to Oreo:

You could try OTG flashing the Oreo sdupdate.img, fit SOM back to headunit and then try loading the Full Oreo update.zip from USB. Otherwise I will need to upload the full Oreo partitons dump with instructions....over the next few days....
[MTCD Hardware Development] lucajust:
Thanks... What are the "SOM"?

Inviato dal mio Mi A1 utilizzando Tapatalk
[MTCD Hardware Development] Harsesis:
It is my understanding that I can flash the SOM without the rest of the board?

So just disconnect the SOM then hook up the USB as per the diagram and it will be detected by windows. Use android tool / RockChip Batch Tool with a android 6/8 recovery.

The issue I have is that the nand doesn't look like its recognised after an attempt to flash oreo. Please see attached picture.
[MTCD Hardware Development] scorillo_ro:
Yes, you understood correctly. This method may save you...
[MTCD Hardware Development] Harsesis:
You mentioned a full partition dump. I'm hoping I don't need this. I remember reading that the partition structure needed to be changed for android 8. Do you have any idea how to do this via the tools? I remember reading about something called a storagemap that rockchip uses.
[MTCD Hardware Development] scorillo_ro:
Wait for @marchnz to put this information here. Meanwhile you can start building your USB JIG.
[MTCD Hardware Development] Clandaries:
Will try this, just have to buy resistord.

One question... How to download from Github?

Edit: Found it :)
[MTCD Hardware Development] scorillo_ro:
Move one level up to https://github.com/rockchip-linux/rkbin then use the green "Clone or download" button, then select "Download ZIP"
[MTCD Hardware Development] Malle355:
Finally I hear the Windows connecting sound. But my Device is still not detected. It says "usb device not recognized". I thaught it would be the driver but I installed the v4.5 Driver. Any Ideas?
[MTCD Hardware Development] scorillo_ro:
Maybe you need to switch green and white usb data wires...
[MTCD Hardware Development] Malle355:
Yeah already tried that. Also tried it with a different PC both Windows 10 but same problem. I also tried to a other SoM but this one got the same problem. I really dont know anymore what to do :confused:
[MTCD Hardware Development] scorillo_ro:
Strange. I only used Windows 7.

You can also try using a powered usb switch. Maybe the USB ports you used does not provide sufficient power? This is just an assumption.

Or, as [MENTION=4974080]marchnz[/MENTION] said, you can try enter maskrom mode.
[MTCD Hardware Development] Malle355:
My Device is only getting detected in MaskRom Mode. Its not getting detected in Normal Mode. But as I said it says "usb device not recognized".
[MTCD Hardware Development] scorillo_ro:
Did you try to upload a firmware image from maskrom mode? The other mode, not working for you, is called loader mode and is provided by software that might be corrupted.
[MTCD Hardware Development] Malle355:
Cant upload the Firmware from MaskRom Mode. I got the "usb device not recognized" error. I never goth my the device in the loader mode. My PC never detected the SoM in loader mode.
[MTCD Hardware Development] marchnz:
That's very different. I wonder if it's a FYT SOM as used by Joying.

Regarding recovery, to force recovery via the recovery signal or get OTG I would think be a challenge without a schematic diagram. The breakthrough for HCT MTCD units was a schematic listing the SOM pins with descriptions. Without that I doubt I would have been able to find hardware solutions as posted in the OP.

Wish I had better news for you. Could you try requesting a schematic from the reseller?
[MTCD Hardware Development] Taechit:
Thanks marchnz.

I'll tried to ask for a diagram from the seller first.

This is the unit I've bought. Actually, I think it's not exact MTCD.

Weird input voltage for pin20/28

I bricked my px5 device by trying to write malaysk's sdupdate.img using recovery (somehow brainfarted and though the sd boot method could be required only when you couldn't get to recovery. I also couldn't make my device boot from the sd card).

Anyhow, I've now made two separate attempts to solder USB cables (one USB 3 and another USB 2) and when attaching to computer's port, I can measure the input voltage for pins20/28 to only 1.5 volts which falls short of the range 1.8 to 3.3V. The last try was with 12K and 22K resistors and I have also tried 12K and 15K resistors. The input voltage for pin 1 is 5V.

I guess since I'm not able to produce the required input voltage for the pins the device is not recognized by Windows when attaching. Correct?

The thing is I don't understand how the input voltage for pins 20/28 is so low? I've also tried a USB 3 hub in between with no effect. What the heck is going on? Any ideas?

Edit: could it be the USB device is not recognized because it's not in the maskrom mode? I saw a post discussing maskrom pads (?) linked in the first post but failed to understand how to get to the mode.

[MTCD Hardware Development] Clandaries:
You tried a active usb-hub?

My usb-ports did not give enough power so i had to buy and use a active usb-hub.

Regards
[MTCD Hardware Development] tonijuvani:
Yes actually now when retrying with an active USB 3 hub that has regular USB ports too (don't know if that matters) I can see the voltage at 1.87 which should be enough.

However, no detection/nothing happens in Windows. Does this mean I need to get to the maskrom mode?
[MTCD Hardware Development] tonijuvani:
I added another 12K resistor in parallel with the existing 12K resistor. Now the voltage at pins 20/28 with or without the active USB hub stays at around 1.87 volts which should be sufficient.

I then removed the heat sink and found the pads to be short circuited for maskrom. Found more info in the other thread https://xdaforums.com/android-auto/mtcd-discussion-questions-development/px5-stuck-bootloop-t3635412

Procedure: 1. Short circuit the pads with tweezers 2. Plug in USB connector 3. Remove tweezers after a moment

=> still nothing happens in Windows device manager.

(would attach pictures but I have no permissions.)
[MTCD Hardware Development] marchnz:
What is the supply voltage when connected to the SOM? Check connections and try other PC.
[MTCD Hardware Development] tonijuvani:
Supply has consistently been 5 V or a bit higher. I've tried with a borrowed Windows and my own linux and mac hosts. Nothing detected in the USB interfaces at all.

I quadruple checked all connections and voltages and made two separate cables just in case.

[MTCD Hardware Development] TerAnYu:
tonijuvani, It is necessary to step back 2 pins on the left., Look carefully at the picture in the first message.
[MTCD Hardware Development] tonijuvani:
Thanks I was definitely using the wrong pins. After fixing that I was getting response from Windows.

However the device was still not being recognized. After a lot of redoing things and double checking I ended up connecting the USB ground to pin 4 like suggested in an earlier post. That got me a bit further in the flashing process but it was still failing at the firmware verification step.

After noticing that moving the position of the data cables (white and green) made a difference in how far the process would go, I somehow came up with trying to wrap these two cables in tin foil. Suddenly all flashing attempts started working!

However, I'm still not there yet. Firstly, I tried to write Malaysk's recovery in order to then update to oreo using the update.zip file. However, I no longer can get to recovery like previously (long press reset and then click again after blinking). So that failed.

I then tried kumarai's image and wrote it using the OTG cable. No luck there, still can't get to recovery

After that I tried to restore the latest android 6 image. That worked well and the regular gui starts, but still I cannot get to recovery when trying. Also, wifi and Bluetooth is not working.

I think I previously clicked all the erase/format buttons with the tool prior to attempting to write a new recovery.

Did that cause troubles? Why am I not able to get to recovery anymore after writing malaysk's sdupdate.img?
[MTCD Hardware Development] scorillo_ro:
You most probably damaged the SOM connectors, maybe by using too thick pins. Try bending a little the pin corresponding to recovery on the main motherboard to make it have connectivity to the SOM. Do the same for the other pins (wifi and bluetooth).
[MTCD Hardware Development] segaxavier:
Hi guys, humble request if anybody in Australia or new Zealand can help me flash my SoM. I have made a usb OTG and connected the usb cable the board is not detected by the PC (no usb device connected). Tried to make another cable and tried different PCs but no success.

Hi guys!

After trying to flash my xtrons hct-px5 rev 8.0 using SD card, it got bricked (buttons led lights are on but screen is off, not black but off)

I am trying the otg USB method on Windows 10 on multiple computers but Windows can't detect it.

I tried two different USB cables with 12k / 15k resistors, I got 1,8v on pin 20 and pin 28, 5v on pin 1, still nothing.

You are my last hope

Hey [MENTION=4974080]marchnz[/MENTION],

Wondering if you could point me in the right direction here - got an PX3 RK30 Android 7.1 car unit that needs reflashing and saw your how-to.

It's got a USB plug (bottom left of the white cube, 8 pins) but I think it needs drivers to operate.

With regards to your OTG setup, where would I place the header pins? Presuming on the CPU board (top right)? This seems soldered to the MB and I'm not sure how to remove it...

Any advice greatly appreciated!

Earlier, in this topic, it was pointed out that short wires solve this problem.

It is necessary to have a shielded USB cable, and a minimum pin length for connecting this board.
[MTCD Hardware Development] polgoz:
Thanks TerAnYu, but there's no way.. my USB cable is shielded, short and always the same loop on pc.. detection and unmounting with warning about hardware.

Error 10 - check USB Data (+) & (-) are not swapped. Also, check USB supply remains at +5 - that your USB port supplies sufficient power for OTG.
[MTCD Hardware Development] polgoz:
[MENTION=4974080]marchnz[/MENTION], first at all, thanks for all your work bulk here. Is amaizing. Really Thanks for that.

I try the connection to USB 1000 times... I try everything (swapping USB data, puting 0v on pin 15, puting +3.3v on pin 9, add +5v to pin 2 and 3, etc...)

When I meassure USB (+) supply before connect to SOM is 5.0V, but If I measure with SOM connected, I get 4.8 volts, that can affect it?

When I connect direct to USB in mobo, SOM is not detected by the driver, but If I connect SOM across the same port but splitter by a Apple USB keyboard, then SOM is detected by drivers but cant be up more than 10 seconds.

How can I know if SOM is simply burned or totally damage?
