How to get into Bootloader

Hi there!
What key combination gets me into the bootloader?
I've been wondering and searching for a way to upgrade my MDA pro rom. (searching for hours on xda, google and a lot of other specialized sites. Turned out to be dead ends! FRUSTRATING!
I'va had a Qtek S100 before. There was a way to get into the bootloader. And there is a way into the bootloader for the Universal to! YES!
But when i try to push the buttons
on/of
Camera
reset button
i cant get in!
button 1 and 2
reset
the same problem.
I get as far as the pres 0 or X for factory default and exit.
Who can help me? I have the no_id upgrade utility and the ROM ready.
Was there a UUL file which i had to edit before using this upgrade method?
I hope there wil be a good tutorial for this just like the one i have used to upgrade my S100 to an orange rom. (worked great!)
Can anyone help me please

Its BACKLIGHT BUTTON + POWER BUTTON + RESET HOLE
It's better to do this without the SIM and Memory Card connected. Disconnect also the USB Sync Cable.
After entering bootloader, you will see SERIAL written on the screen but the screen has no backlight so you have to look hard.
Then when you plug the Sync Cable, the SERIAL will change to USB then you can run the NoID to update.
Remember the NoID has to be run twice in a row as the first time usually solicits an ID Country error

It Works
Thanks Jorge!
Just those keystrokes helped me a lot. It works just fine and it took me only one run to Initiate the upgrading.
Thanks a lot!
I followed your advice and removed the SD and the phone card.
Yes! now i can experiment with these ROMS.
First Jasjar, later O2 and hoping for the best roms with the best programs.(hoping to find a messenger cab file in the jasjar rom)

As I am planning to do the same, Try all the variants of the ROM's, could you inform me what are the good and bad points of all the different ROM's you used and which did you decide to use finally.
Thanks

HELP !!!!
I turn on my Qtek 9000 and i see SERIAL written and the screen but the screen has no backlight.
How can I boot my Qtek 9000 again without this SERIAL mode ????
Best Regards

Hi Ecraseur,
if You did not do anything else (no upgrading), try ColdReset : Power-switch + Reset hole.

If we can boot from Serial/USB is it possible to boot from Mini SD? I'm toying with the idea that by using a Linux Live Disk content on a Mini SD it may be possible to boot into a virtual Linux environment? I know it's going to be uber slow and may not even work but I thought it may be worth a look?
If a Mini SD boot isn't possible do you think it'd work to have one of the smaller USB bootable Linux flavours as the USB boot for the HTC Wizard etc?

Bootloader dead / Recovered

Hi,
I made a mistake with flashing QTEK S200 with wrong file.
Bootloader was modified. Device can not start at all.
It can not even go to bootloader screen (red-green-blue).
As consequence, no USB connection can be established.
What is the solution? I guess utilities can not be used, because they assume connection to USB, but there is no connection.
Not big deal, because it was not working well anyways, but would be interesting to know a solution in this case. Many ppl. would be happy to know how to manage this situation, I guess.
later.

Not very good news, service center said they don't know how to fix it, but kept the device to make few things with it.
Clearly, bootloader was overwritten.
Will see. Somehow they manage to identify type of rom is installed from i-mate.
So, think before you make any flashing
re: another service said they will do whatever needed, up to replacing chip with flash. I am not ready to go that far yet.
feel like i am missing something

It appears to be a real problem with flash.
No connection to computer with USB.
With power supply connected blue-green-?? screen, but I cannot connect to PC of course.
With USB cable connected blue-green-?? screen does not come up.
I figured out that pins 4 and 5 are shorten when power supply is connected. I did this with USB connection to PC, but still not connected.
For sure, USB is not functioning on device.
Will get new device, but very interested on how to repair this one. I disassembled it completely. There is no way to replace the flash chip at home, you need specific equipment and chip, of course.
What I need is surcuit diagram for S200 or similar, particularly part of diagram related to flash, radio module is not needed. Is there any possibility to get it? If I have it, I think can reprogram chip.
Thanks.
Hm. It looks like extreemly difficult to get pins layout on motherboard.
JTAG is the only solution left to access chips direct. But we need to know where JTAG pins on motherboard.

Recovered S200.
Finally very good news!
Prophet S200 was succesfully recovered with help of Arc.
He managed to discover JTAG pins, afterwards re-flashed SPL and ROM.
REALLY GOOD JOB!
Want to say special THANKS to Arc!!!
Device go live again.
Until next experiment....
But procedure to recover is in place.

i have a dead one too
Hi there,
I have a dead one too can you tell me how to fix it please?

dead, as in my ppc k-jam is dead
basically it hangup and i soft restarted, tried hard reset. it didnt help either. i tried restoring to factory default same thing it hangup. now it doesnt shows any signs of life . i lost my life, my buddy.

My Orange SPV M2000 will not start anymore after update. I only see Serial (on top)............ V2.07 (underneath)
I tried to update my ORANGE SPV M2000 to Tmobile's newest rom by extracting the exe. file and using maUpdateut. It started well and all of a sudden gave error "country code................"

You will not be able to fix it yourself.
Equipment and phone required physically in order to connect jtag interface and re-flash DOC.
Sorry, but this is the only solution if your bootloader is damaged.
Of course, you can try to ship it to service center. If you are lucky they will change your device. This might more simple.
Good luck.

I know how to open device and solder some wires to testpoints. Do you have any information where the pins are located and what software and what JTAG adapter you used? I really need to get my phone working again. It was quite expensive to purchase and to ship it to my country. Please don't destroy my hope.

hello friends,
my cousin recently buy O2 XDa ( wallaby ) for cheap one, i check on device it seems cann't boot to windows but if i hard reset and came up red, green, blue and if i press ok it came up with test all thing i confuse all the test is OK, can you all tell me how to repair the phone and waht is the problem?
thank you

dead device hope on the horizon
note my device and troubles is on the xda2
hi - i have had exactly the same issue - i have managed to reload the rom i was trying to swop and here is what i did .... it took ages and lots of patience and it is not an exact work of science but if you try my method 2 or three times it actually comes back to life ... honest !!
down load an xda2i ( yes xda2i )rom extract it using winrar or zip on your pc place dead xda2 into cradle regardless of whats on screen run himupgradenoid - the rom will run and start to load onto your device it will fail once it has failed remove xda but do nt reset - take copy of original rom which was on the device prior to your failed upgrade and extract as above. replace xda into cradle might be detected or not dont worry - run the himupgradeut from your previous working rom and wait it takes ages to connect but eventually heypresto ... you will have a working device. i know cos i done it !!! - i have not resolved all my problems yet - i still want to load latest 02 rom but even after entering correct device data into nbfs using batch file method the device crashes saying incorrect counry id. - i accidently created my problems by accidently running the wrong upgrade rom and i guess it changed somthing on my device " country code" however when i use method above to get original rom inplace and working when i extract device data into windows folder on device i still see the wwe ( world wide english) so i am still in a pickle - can anyone help me .

hello
i'm working on the project of flashing the bootloader into a totally erased and dead phone. can you send us the test points from the prophet please? and if you know their location on a WIZARD. thank you..

Somebody here Please tell what soft to use with JTAG to recover da bootloader!!!!!!!!!!!!!

get the JTAG pins for me, I will send you soft.
Wizard and Charmer pins are both needed.

hi, i've succesfully wrecked my Blueangel PH20B by flashing a modded wm6-universal-rom... i've got all the hw & sw to resurrect the phone but the jtag pins on the BA-PCB...
can someone give me a hint where i may find them? (i'm not wanting to bake the pcb as i know i'll wreck it comletley)
thanks in advance,
mario

Same problem here
Hi,
I believe I'm having the same problem
Please help me
Thax a million

so can you help me i need to write the wizard(g4) bootloader or thell me how can i do this

T-Mobile USA SDA II
Me also, i'm i need of re-writing boot-loader of T-Mobile USA SDA II

well, ok I understand that you can get the Jflash_mm working with PXA systems, you can write the definition for yourself, as for the CPU.
but I have serious doubts that inspire me to suggest you will have tiny chance to actually program a DiskOnChip Millennium series (or familiar) chip used in many platforms (actually I believe most HTC devices).
after all this means that if you are not working for (or in affiliation or partnership with) SanDisk, you are not in position to program bootloader to (not limited to) UNIVERSAL, WIZARD, PROPHET, and CHARMER (and if I remember well, BLUEANGEL and HIMALAYA) devices over JTAG.

Enable apps to read OTG USB contents in Marshmallow/Nougat

If you are trying to use your OTG USB as music or video library in Marmshallow or Nougat, but your media player doesn't recognize the content of your usb, then follow these instructions.
Download the terminal from store in case you don't have one. Root is required. You only have to do this once:
Simply open terminal and type:
Code:
su
sm set-force-adoptable true
Now just insert OTG USB and it will be immediately recognized by music players and all other apps.
Additional info:
Do not safely eject the usb, in my case doing this I noticed some bugs, just directly unplug the otg.
My phone is LG G2 d802 and the rom is CM13 snapshot 20161220.

It Works, than you!
I tested in Lineage OS 14.

I want to try this, but I am using Nougat now. So, just in case it didn't work, how should I revert the code above? I am new to this thing actually. Thanks!

I'm using jetAudio plus, everything works great, thanks!
(Nexus 5, 7.1.2)

I am not sure what happened or why, but this has suddenly stopped working for me. ?
Edit: Appears I might have been a bit hasty, looks to be working just fine now. Only thing is, there's no notification for the connected drive. It's a tiny little inconvenience, I know, but I prefer it was there. Any help would be much appreciated.

It's been a while since I thank you someone from Xda and all I can you are a genius!
I have been looking for a solution for days now for my nexus tablet car project. I bought a Tpms from China (I am about to return it actually) and it is not working due to some stock Rom external restrictions for Android 6.1 even I am rooted.
Again! Thanks to you Buddy!

Does the "sm set-force-adoptable true" setting change how sdcards are managed?
Do SD cards and USB sticks become readable only from the Android device?
Are SD cards and USB sticks formatted / deleted when connected to Android?
Sorry for the perhaps stupid questions, but until now I was sure that an adoptable memory was not readable by other devices.

Does this trick still work in Android 9?

I have this problem in Android 9, on a PX6 unit.
I cannot use external USB SSD disk, or USB stick for my MP3 archive.
Can anyone point to a solution for this that does not require rooting, or can anyone point to a very simple solution for rooting this device?
Very thankful if anyone knows.
I tried the command "sm set-force-adoptable true" and it will not work, it does not find the command SM.
Als the SU command will not run. I guess because i am not rooted.
Any suggestions here?
thanks!

AC8227L - Mediatek components + unknown MCU - Bricked device help from PCB pictures

Hi all,
So I managed to successfully root and dump various bits of firmware etc over the past few weeks and generally had no issues(apart from the LED front panel lights not working(did at first), which is the main reason I was trying to rectify) - I have flashed from USB using a .bin also dumped preloader and rom etc via a scatter file using SP Tools after finding a rom entitled 8277L in the filenames, this worked perfectly(but still without the LEDS's) - Link to bought device(a cheap chinese one) - https://www.ebay.co.uk/itm/Single-On...53.m2749.l2649
Main issue: Now I have bricked it - I selected the format all part in SP-Tools thinking it would allow me to flash from fresh to stop the stock and TWRP recovery from timing out(I successfully ported TWRP over, but after about 30-40 seconds it was rebooting the device, bizarre!) - When the head unit is powered on it turns on the display but that is all, just a light black screen. I've tried recovering again via USB and SP tools but I think I'm almost out of luck. SP Tools doesn't read from the device or detect it, and yes I have the correct drivers installed under Windows. No screen swiped or button presses help in getting into any bootloader or update mode.
I am really hoping, anyone could help identify the UART pins on the board - yes I've now taken it all apart - in the hope I can flash a bootloader image which I guess is what is now wrong and has been erased??
I've really been digging into this and researching on Russian websites and getting lot's of interesting information including from XDA thankfully, but not this issue. I have included some pretty much hi res images, some are dark but I have redone some, everything is readable but I've googled and googled for model/part/serial numbers etc and have had no results that helped to indentify where I could potentially find the UART connection.
If anyone has the same unit or similar it would be great to share the knowledge so perhaps we can help bring the info together and help other debrick this device if there are any!
Many thanks, for anyone who cares take a look!

Steps to take to clear Version Unmatch_01

Hello everyone.
As a junior member, I'm getting wiser everyday, but still would like some advice on the steps I need to take to clear the Version Unmatch_ issue on my PX5 MTCE HU.
A friend of mine installed a wrong MCU version on my HU, but didn't export before flashing.
My MCU is a MX2 version, and i've been told that I can use the newest MX as well, but after flashing the new MX V3.08 it still comes back with Version unmatch. No sounds, and all the knobs don't work anymore.
Can someone tell me in steps which actions I should take to make the HU work properly again. Note like I said, I don't have the original config file anymore.
By reading through all the treads my head spins , I don't know where to start......
People talk about different things like McuUnmatchUnlock.apk anfd manual config, install reboot, config file will be restored etc etc.
to be sure I used to have MCU version MTCE_MX2_V3.01_01, now i've installed MTCE_MX_V3.08
I would appreciate your help. :angel::angel::angel:
Noël

İnstall the MTCE_MX_V3.08 file from USB. Do not update the MTCE_MX_V3.08 file from the SD card.
