Erisin PX5 Stuck in Recovery Command/Shell - MTCD Android Head Units Q&A

Last year I had upgraded my Stock Erisin PX5 with version 6 , to version 8.0 (Hal9K ) using the RockChip update tool . I also updated the relevant MCU version . It had been working fine with the HAL9K upgrade , until the end of last year the unit started slowing down . I remember clearing the cache from the recovery menu thinking this would help but ,since doing so the unit has been practically bricked . It has not been working since . Upon turning it on , I just see a shell/cmd menu flash for a fraction of a second , then nothing - see below
View attachment 5077245
I have since attempted re-flashing the 8.0 HAL9K and a 6.0 stock image , sent to me courtesy of HAL9K via email . I fruitlessly created several bootable upgrade SD cards , using the Rockchip tool (1.56), writing the system image files to the SD card . Upon inserting the upgrade SD cards , into the GPS slot I just get a 'Upgrade card' or generic 'Navigation system' splash menu and nothing else, I waited 10 - 20 minutes each time . As shown below

This PX5 I think does not have a reset switch, though it does have physical buttons and a power button ( see images above - the two holes are mics? ) , holding the power button for around 10-15 seconds , 'resets' the device , the lights flash twice after doing so , I think this ' long press power' also is supposed to open the recovery menu
I have contacted Erisin for some support , I am hoping they can send me some instructions to flash a stock ROM . Below is the system information with the stock rom and MCU for reference purposes , obviously these are not the current MCU or ROM version but , the images should give some indication of the intricacies of the device .

If anyone has some information on how to flash stock firmware , please reply . Many thanks . I understand all PX5 firmware should be interchangeable between manufacturers but the MCU version is unique .

problem resolved
now it works.
i tryed to resolve it with this link from hal9k post nr. 3116
https://forum.xda-developers.com/sho...postcount=3116
i used a 12 sdgb card but it didnt work. so i changed to a 8gb sdcard an now the unit has been started!
thank you for the suggestions

then i flashed a different firmware(onda v140) on it and the screen went white when powered on .
then again i flashed my default firmware everything is working now but touch screen is responding very differently . this is a capacitive touch . i have even tried flashing those firmwares which were working perfectly before but now the problem is common in all firmwares i flash .

same problem . please somebody help
have you tried to shutting it down by holding power button for a long time (it will skip the do you want to shutdown option) and turn it back on again?
i had a trouble once with mine. a lot of resets (the small hole button) and reflashing ICS did not help. but strangely when i shut it down normally like that, it came back normal
edited: sorry if it doesnt work, my problem came suddenly, not because of changing firmware.
Don !
I Know how to make you solve your prob ! Just flash momo9 compatibility 1.2.0.zip:good:

[Q] Goclever R75 (7500) - boot freeze (bootloop ? )

Hello. After factory reset my goclever does not stand up. It freezes at android logo and nothing happens later (no reset, just android logo). I think it might be because after installing apex pro i deleted stock launcher. Device manager sees it as ' Full AOSP on Rk29sdk ' (but cannot copy anything to device) and ADB sees no device.
Is there any way to do something ? Christmas are soon, so i will not send it to service cenrte.

Goclever hasn't published any R75 firmware yet. Also this tablet doesn't have any physical buttons except power switch. On my native language forum was sometime ago rumor that on downside motherboard is switch which combination with power button gives recovery menu. Personally i tried various combinations but didn't worked for me.
Any ideas ?

Hello.
Which version of the device do you have?
7500
or R75
Those seems to be the same but are different.
I have stock android version for both
for 7500 - original, unrooted ( from a Russian site - don't remember)
for R75 - original, rooted ( a dump created by me from my device when I have received it)
Both works, were tested by me on my R75.
The firmware of 7500 flashed on R75 works, but you won't be able to use the capacitive buttons (as I told you are different).
The flash option is very simple:
1. Copy two files on the root of the sd card
2. Insert the card in the card slot of the device.
3. The flashing process will continue automatically.
Just tell me which one you need and a place where to upload the needed firmware. I can do the upload this weekend.
Regarding ADB, hmm... this is strange. I have done the same thing as you (deleted the launcher and restore to default) but adb was working with device in the android logo state.
I'm using Windows 8 and I have installed the device as test ADB device (from windows drivers).
Bye.
Edit:
This is the link for R75 rooted firmware.

This is the link for GoClever tab 7500

Bye.
On the back he have written that he's tab 7500. Soon i will try to flash him with your 7500 image. Hope it will work ^^ Thank you very much.
Everything on first look is working on. Except wifi card, which doesn't turning on.
/update
R75 software fixed it. Don't trust manufacturer anymore.

hello
this may help some one later
to get into recovery if your R75 table wont boot you have to take it apart the button is on the underside of the board behind the screen (silly place to put it) i have being talking to goclever support and more firmwares are going to be added to the site. if you want yours adding send them an email requesting it (one may not be enough ) i have just had this problem and after a month they agreed to take it back and have reflashed it for me
hope this helps someone

I can't change my rom, wipe / format doesn't work. Nothing changed after flashing with Odin.
16 GB Tab 2 have a known faulty EMMC (MAG2GA). It can happen, that your EMMC get "read only", so you can't perform any write actions (also you can't format) anymore.
From the EMMC data sheet:
5.1.7 End of Life Management:
The end of device life time is defined when there is no more available reserved block for bad block management in the device. When the device reaches to end of its life time, device shall change its state to permanent write protection state. In this case, write operation is not allowed any more but read operation are still allowed.
But, reliability of the operation can not be guaranteed after end of life.
On a faulty EMMC firmware it happens a lot faster.
What are the symptoms?
Uninstalled apps and deleted files are back after a reboot
Formating the storage doesn't work (after reboot the old rom and apps are back)
You can flash whatever you like via Odin - it showes "passed" but after reboot nothing changed (e.g. still no StockRom or still the old Recovery you had previously installed)
... there might be some more, but only to mention some ...
In most cases, the issue can be fixed by a EMMC firmware update, but you need someone who's able to do it (possible via ISP, nothing you can do esylie at home yourself). In some bad cases you need to find someone who can replace your EMMC.

i dont understand why it always gets in recovery mode with the sdcard which already bricked the unit.
understandings from readings
it doesnt get into recovery mode because it stucks or something went wrong on previous update.
To get in recovery i remove som from board, prepare a cable with 10k and 20k resistors. measure 3.2v from cable. And attach the usb cable pins to som’s related pins. Pc recognise the som, run the rk tool app, load stock 5.1.1 rom. And click restore button, succeed the restore succesfully. Plug the som back to board, push the reset button. it stuck on boot lollipop logo again. İ i tried to restore both dupdate.img and sdupdate.img by one by. Doesnt work.
The only thing that work is the hal9k’s nougat 7.1.2 rom’s sdupdate.img. İt takes recovery menu, i can wipe data, wipe cash , update mcu and update firmware. (Update firmware option only updates nupdate 7.1.2 version which is stuck on boot logo again)
i will flash mcu tomorrow by stlink method. i think mcu is fine. it wont work again.
İ create sdcards with Rockchip Create Upgrade Disk Tool v1.46 (SDBOOT 2.12)
update,
remove som, take it to maskrom mode.
with tool androidtool 2.3
eraseflash
lowerformat
upgrade firmware.
it doesnt work still.
i guess i need fully erase nand partitions and make it as virgin . but how?
installed virtual machine and ubuntu to fix by rkflashkit but, it cant recognise usb
