I have a G9350 so SD820 with an unlocked bootloader, sorry if I'm misunderstanding but this should work on my device right? Also am I right in saying once I've flashed a recovery I should be able to flash SuperSu and have root access?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] dongdong6968:
you can't flash a recovery without root access lmao, and there's no way to flash it from outside of the phone either. There are a bunch of redundancy security checks built in that make it so if you beat one, then the others will ruin your day.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] randomhkkid:
Interesting, that's new to me haha. I've obviously been out of the samsung game too long. Isn't the recovery flashed through Odin? I wasn't aware that odin needed root access to flash recoveries. And are the redundancy checks built into all S7s, I thought it was only the US models with dm-verify etc.

This thread is for us models only
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] randomhkkid:
The dev says that the recovery is for any Qualcomm variant.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] seanvree:
This is correct. You don't need root access to flash a recovery. You get root access after the recovery is flashed of you go about it with ODIN from a computer.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] randomhkkid:
Cool thought so, gosh its infuriating the variation in models causing misinformation. Though I still won't be flashing anything until there's more progress in terms of development :D
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] seanvree:
Yeah, after the recovery is flashed you'd need to flash a kernel and ROOTED firmware, which DOES take root access.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] the Doctor:
No, but you do need an unlocked bootloader to flash a non-signed image such as TWRP. That's why this thread is doomed.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] randomhkkid:
I have an unlocked bootloader :D

---------- Post added at 11:07 PM ---------- Previous post was at 11:06 PM ----------

I'll read up on this, I'm guessing you mean I have to flash a rooted firmware as opposed to just superSU to achieve root.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] the Doctor:
Ok, so yeah, the Chinese version. I still wouldn't flash a TWRP recovery that is a work-in-progress and nobody including the dev has tested unless I was sure I knew how to get back out of the hole.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Tkkg1994:
Encryption is enabled by default. So this here is happening because twrp doesn't support samsung encryption. So it can't read the data

---------- Post added at 03:47 AM ---------- Previous post was at 03:45 AM ----------

Nothing new for the US versions. Ah so yet another barrier, I know some chinese devs have successfully used a modified TWRP in order to flash things so hopefully there's something soon.

Google Play store TWRP says it's only version 1.2 in the description. Downloaded the 3.0 version here and backing up with flashfire before I go any further. Did the JRKRUSE root with Odin, but it seems like it made it sluggish and gps is not so stable. Gonna try LightROM. Device Im on is the VZW-G930VVRUACSH1. Oreo platform. Seems like the LightROM is a Pie version. Anyone upped this baseboard to PIE? Stable?? Thanks!

My snapdragon galaxy s7 keeps failing to flash. i made the .tar archive with 7zip and flashed with odin. but no matter what i did it doesent work.
[MTCB Software Development] ahfunaki:
I wish I knew exactly what caused this to happen. I was using a Malaysk ROM and starting having the issues. I thought maybe it was the ROM so I downgraded back to the original ROM that came with my unit and I'm still having the same issues. I downgraded through system updates in settings.

I can get it to boot into recovery, but it's just a black screen with pulsating light blue lights on the side of my unit. I have a Joying RK3188 1024x600 with the touch buttons on the left side.

Also when the unit boots up I don't get the Android splash screen anymore, it's also black. The first sign of life is when the car logo screen pops up.

There have also been multiple cases where when I am using the unit the screen has turned black ( if the radio is playing it will continue to play though ) and I can't do anything on the screen. This has to be a related issue.

Does anyone have any idea whats going on here?

I appreciate any help I can get!
[MTCB Software Development] ahfunaki:
Anyone have any ideas?
[MTCB Software Development] pa.ko:
Try reflashing both MCU and ROM.

Use USB method for recovery of brick unit.

Or try reflashing from GPS card by mimicking procedure as it should be done on screen working even if you don't see it (look for screenshots of recovery and try to perform needed actions - somewhere here was such hint for someone whose screen brightness was completely darked out and has to perform factory reset from recovery on the blind).
[MTCB Software Development] ahfunaki:
What is USB method? Just load the files on to a flash drive?

And I've found a picture of the recovery menu and I've tried that multiple times with no success.

Thank you for your help!
[MTCB Software Development] ahfunaki:
Putting the stock MCU and ROM on the GPS card fixed it! I did the update from the settings menu and it worked! I have recovery again! Thank you so much for the help!

I really want to install the custom ROM again, but I really don't want to keep having this issue though. Does anyone have any idea what is causing this to happen?
[MTCB Software Development] pa.ko:
I had bad experience with MCU v2.83

After some time it started to make touch screen not working, factory settings pass not recognising standard 126 etc.

After restart - all normal. Then for no reasons next day problems rrapear...

Reverting to stock v2.80 resolves issue. And Nalaysk ROM works with no prob.

So, if you upgraded MCU - that may be a reason.

If not, then maybe your ROM file was corrupted. Or your internal memory got corrupted somehow.

My prob with newer MCU, not working on cold morning first start but working after reset, points out that there is some HW related issue. With new version only though! Figure it out...
[MTCB Software Development] ahfunaki:
I never updated the MCU so I'm really not sure what happened.

I'm actually don't mind using the stock ROM minus the fact I've already ran out of storage, is there anything I can do about that? So many things are working better for me now. Before I wasn't able to get an OBDII adapter to connect to torque and now it works perfect.

I'd love to go back to the Malaysk ROM but I just had so many issues...
[MTCB Software Development] gk66:
Use link2sd to store your apps on an external sd card.
[MTCB Software Development] pa.ko:
There is also another ROM, look for thread named Interesting ROM with FUSE support.

It is almost stock but with FUSE partitioning so you have all space for both sys app and data.

BTW your prob with OBD2 is known issue in Malaysk ROM if you enabled xposed BT module.
[MTCB Software Development] ahfunaki:
I actually tried that, but I couldn't get it to run on boot. It didn't seem like it was working too well for me but maybe I was just doing something wrong.

I will look into this, thanks again!
[MTCB Software Development] gk66:
You need to root your head unit. Use the root code from the wiki. Then install super su and give permissions to link2sd. Remember to properly partition sd card ss well
[MTCB Software Development] ahfunaki:
Thank you for the help, I ended up just installing that other rom with FUSE so everything is good now.

Really enjoying this thing...

[MTCB Software Development] RS-TLS:
I have the same problem now. I just went into recovery mode and installed update_4_4_4_FUSE_1024X600_RK3188_17_MAL_23_04_2016.

All was well until the Android loader image just sat there pulsing. The unit still had not started up after 40 mins of this logo being on screen.

Going into recovery mode just shows a black screen now. So my unit is effectively dead, or can it be rescued?
[MTCB Software Development] RS-TLS:
Anybody able to help me out here?
[MTCB Software Development] MueKo:
Is it possible to start your device normal?
[MTCB Software Development] RS-TLS:
No. It just sits at the bootloader.
[MTCB Software Development] MueKo:
Try in recovery mode to enter back in normal boot mode. It's difficult to explain in englisch. I had to pin a small needle into my radio and ca. 0,5 seconds before the LED are flashing, stop with pushing. When you stop pushing you must wait 5-10 second and see if you device boot up normal.

You have to try this often to find the correct moment. Thats how I entered back to normal boot mode.
[MTCB Software Development] RS-TLS:
I have tried this, though my unit has no LEDs or buttons. I use the needle to reset the unit when it is stalled at the black screen that should be the recovery mode. No amount of combinations of needle presses seems to do anything.

Thank you for your attempts ot help me though, appreciated.
[MTCB Software Development] MueKo:
I mean with LED the Light that is flashing when you push the needle. The light wil be flashing every 10 seconde when you push. you have to stop pushing the needle direct before the light flash. I did this also 20 minutes to find the correct Moment. Try it again and when you succeed I wil help further.
[MTCB Software Development] RS-TLS:
Sorry, I have no LED on the unit
[MTCB Software Development] MueKo:
where are your buttons? No light behind the buttons?
[MTCB Software Development] RS-TLS:
It's buttonless. No buttons at all, just the display panel, RST indent and above this the reset hole.
[MTCB Software Development] MueKo:
How to use it, do you have a remotecontrol?
[MTCB Software Development] RS-TLS:
It came with a wireless steering wheel button array which is pretty awful if I am honest. It powers on from the ignition key and the panel displays the volume controls etc.
[MTCB Software Development] MueKo:
Is the panel display flashing up when you push the needle in the reset hole?

If yes, this is what I mean with flashing LED light.
[MTCB Software Development] RS-TLS:
Nope, no flashing at all. If I allow it to boot normally I just get the pulsing ANDROID logo. It never gets further than that.

However, if I press the RST button, then wait for the Welcome screen to show and hit the reset button 4 times quickly, wait for the ANDROID logo to appear and long press the reset button, it boots into a black screen. The back light is on though. Even more weirdly the unit connects to the bluetooth on my phone! So it is not dead as far as BT is concerned.
[MTCB Software Development] MueKo:
It looks like you used a wrong imag. I can't help you further, but I think you have to flash you radio with original radio image by using usb connection with a computer. Sorry I don't know how to do this. Maybe Malaysk van help you further, ask him.

RECOVERY UNIT SLAIN to RK3188

It recommended for those who have no-OTG port and mechanical buttons

(Responsible for the consequences rests with you)

Download the archive, unpack it to any folder .

Attached faylSD_Firmware_Tool.zip (489.51 Kb)

The archive is SD_Firmware_Tool.exe program. With its help, we will prepare a boot card.

We also need:

1) Windows PCs having a card reader

2) the microSD-card for 2 - 4 GB (in the process of all the data on it will be erased).

3) The firmware (file update.img), compatible with the processor and a screen resolution of your PG. Desirable - the same one that was on the device to "zakirpichivaniya".

Operating procedure:

1) Insert the card into the card reader PC

2) Run the program SD_Firmware_Tool.exe

3) In the top drop-down list "First: Choose removable disk" select the drive letter that corresponds to the card.

4) The following set box "Upgrade Firmware".

5) Press "Firmware" button and select the firmware file our update.img.

6) Hit "Create" button and wait for the end of the process.

7) Close the program and look at the map. The memory card will appear rksdfw.tag files, sd_boot_config, sdupdate.img

8) Completely disable power radio. That is, even disable BAT wire (yellow), not to mention the ACC (red). It is best to simply pull the main connector on the rear panel.

9) Insert the card into the slot "GPS" radio.

10) Turn on the radio, turn on the main power supply, including the ACC (as a working version - advance include ACC in the car, and then connect the radio to the main connector).

11) Wait a few seconds and do not worry.

12) An indication of the success is a lot of text messages on a black background, similar to what we see during the normal firmware.

13) At the end of the process at the bottom appears "All complete successful! Please remove the sd-card." (Spelling and punctuation of the original).

14) Take out the card and wait for the download radio. If the radio is not rebooted itself after the card is removed, the "help" it by clicking on the Reset button. If the screen is not lit, then briefly press the Power.

Everything - the process is completed.

What to do with the card? The fact that the program format it in a special way, in Windows, you now see it incomplete volume. And it generally can not be used in the radio - or whenever you turn on automatic flashing will go.

The card can be returned to normal size using the same program, there clicking button "Restore". Either keep this card as a tool to restore the radio.
[MTCB Software Development] Malaysk:
Method №2. A connected laptop.

In any case, to report that the radio can flash the "external" method (ie, a computer) - infa from xda-dev and 4pda.

To do this, you need to convert the radio mode "bootloader" - for this you need to connect it to a computer via a USB cable, the front (OTG) slot, and then apply to it the power key while pressing the power button.

Better, of course, for such a case to remove it from the machine.

I continue: The screen is not light up.

The computer requests a driver, which can be downloaded here: http://www.cnx-software.com/2013/11...install-rockchip-usb-drivers-in-windows-xp78/

For firmware will need RKBatchTool program: - View attachment RKBatchTool.zip

Disable antivirus, close all unnecessary programs.

Run RKBatchTool.exe, choose broaching update.img file (it should be on the computer).

We wait sunbathing in green field with the number "1". If gray, the drivers are not installed. Returning to their installation.

Push the button "Update" ( "Update" - if you have an English-language version of the program) and wait for the end of the process.

P.S. This method restores the firmware Android-system. MCU firmware can already perform regular manner, if necessary.
[MTCB Software Development] RS-TLS:
Will try this method and let you know how I get on. I cannot do it until Friday this week now as I am away from home. MANY thanks for the help Malaysk, appreciate it!
[MTCB Software Development] RS-TLS:
Method 1 tried. Unfortunately the unit didn't boot from the USB stick. I've tried a couple of sticks to make sure it was not the USB drive, but it seems the unit won't boot from USB. You can see the light on the stick indicate it has power, but the unit is not trying to boot from it. So, I'll order up a cable and attempt to try method 2 tomorrow.
[MTCB Software Development] Goose247:
I think you perhaps need to use an sd card for method 1 to work and not a USB stick :good:
[MTCB Software Development] RS-TLS:
I don’t have that option as the unit has no SD card slot. :(
[MTCB Software Development] Goose247:

[MTCB Software Development] RS-TLS:
Didn't work at all. I sent the unit back to Amazon.
[MTCB Software Development] tasdevil123:
Edit: This is only relevant for those whose head unit does not boot at all i.e. Black screen and buttons lighting up but the head unit does not boot and does not go into recovery.

I had this issue myself. Black screen on boot and couldn't access recovery at all.

I ended up fixing the issue on my Joying head unit by using "Rockchip Create Upgrade Disk Tool v1.4" to flash the latest stock Joying firmware onto my head unit from an SD card. From my understanding, the utility *should* work for any rockchip based head unit.

***A Warning - I take no responsibility if the following instructions cause damage to your head unit. Follow them at your own peril!***

This is what I did:

1. Download a copy of the stock firmware for my head unit from joying.

2. Download the Rockchip SD card upgrade flash utility from: Unfortunately I can't post a link due to forum restrictions, just google "rockchip SD update tool"

3. Extract the contents of "rockchip create upgrade disk tool v1.4.rar" and run SD_Firmware_Tool.exe as Administrator

4. Select the drive letter of your SD card and tick the "Upgrade Firmware" checkbox

5. Click "Firmware" and browse to the location of the correct "update.img" file for your head unit

6. Click "Create". The utility will now create an upgrade SD card to use on your head unit

7. Insert the SD Card into the "GPS" SD card slot of your head unit and turn the head unit on. The screen should come on and you will see the head unit go through the usual firmware update process.

8. When the update is complete, remove the SD card from the "GPS" slot. The head unit will now reboot and should boot up normally.
