Hello,
I've got a bricked Leo. I've bought it with the description that has fallen down, and doesn't work any more.
Actually the display and the digitizer is fine, but the flex board is cut and it doesn't boot any more. Via USB it is recognized as "Qualcomm CDMA...". I guess it's flashed with a wrong radio as it is the US version.
Can someone tell me what I've to do via JTAG to restore it? Just delete an part of the ROM? Or load the bootloader to a specific address in RAM and start it from there to flash a valid ROM?
I've got the knowledge to solder such fine pitch parts and also have a JTAG adapter that works with open OCD, but don't know what to do in that case.
Maybe someone from Germany is reading this, who has the knowledge and the technique, who I can send the mainboard to flash it.
I would be very glad if someone could help me with this!
It seems to be possible to access the device with QPST. QPST finds a Phone in download mode and it might be possible to download a boot image, OS image and so on.
But it doesn't accept .nbh files. Boot image must be a .hex file. So I tried to extract the spl from a stock rom and build an intel hex file, but the QPST downloader doesn't accept this format: "could not open flash programming file".
Any idea how this hex file has to look?
Have you made any progress?
same thang just happend to me!
i flashed
RUU_Leo_1_5_TMOUS_2.10.531.0_Radio_Signed_15.34.50.07U_2.08.50.08_2_Ship.exe
and all was well but i realy didnt like tmoble logos so i tryed
RUU_Leo_HTC_WWE_1.48.405.2_Radio_Signed_15.28.50.07U_2.05.51.05_2_Ship.exe
and aperently it bricked my phone because it wont turn on now!
i hit the yellow button next to teh battery with no luck the phone is now dead!
it was instantly recognised buy my pc as a cdma phone when it was bricked!
now what?
please someone help us!
You did indeed brick your precious HD2 by not reading this forum. It was stated over and over again that flashing a TMOUS HD2 with a .51 ROM will brick your phone. Flashing is not for the faint of heart. You thought you were in the right league, but alas. Back to the minors with a nice Nokia. Good luck!
I received one of these the other day and began to tinker. Rooted with Gingerbreak v1.2, installed the full market, and busybox. All with no problems. I would like to change a few other things but with out having CWM to make a backup, I am a little cautious. When I go into the FWUpdate, it tells me there is an update. I tracked down the file on the web, downloaded it ( all 300 megs worth) and have been looking at it. If anyone would be interested it this file for development purposes I could upload it or provide the link of where to get it from.
Ive downloaded it. So far it fixes bugs. But you have to use root explorer to clear the unwanted apps

Well I started dissecting the update. Found it is still 2.3.1, it uses fuse to manage the file system, and has an updated recovery. The file system layouts are a little different than what I normally see on my Incredible. It has separate mbr, uboot, kernel, env, system, ramdisk, ect... I would really like to change the density but with out having adb working or a custom recovery, if I use a value that is not compatible I am in a world of hurt.
Yeah its still the same. For nw i currently waiting for cm7 for viewpad 7e. Btw the viewpad 7e isnt big and limited people.

Granted it is not a XOOM or a Galaxy Tab, but I don't think it should be it should be overlooked for development. I am not much of a programmer, but I do like to try. If a current developer could give some guidance as to how to build a custom recovery that would be beneficial.
Andy try power off the vp7e and then hold the power, volume
Up and down button. It resets my tablet.
Sent from my LG-P500 using XDA App
Yep, Power on with volume down boots into bootloader with a boot flag of 1 and volume up while power on also boots into recovery but with a boot flag of 2. Not sure what the difference is with the boot flag. I know that in both modes with usb pluged in, it is seen by my windows computer as a Viewpad 7e. Which is the same thing that is shown when I have usb debugging turned on with usb pluged in after a normal boot. I looked into the adb thing and I cant get adb to see it, even on my linux box. Kinda wierd the vendor id is 0bb0, Concord Camera Corp.
For now we have to wait for a custom recov and cm7 for our tablets

My viewpad 7e keeps rebooting after rooting - please help
Hi Andyav.... I saw your post that you have downloaded the firmware for viewpad 7e. It may be my best chance to recover my viewpad 7e and have it working again.
My viewpad 7e started a reboot-loop after I rooted it with gingerbreak and ran the google market installation.
I need to restore the original firmware but I can't find it anywhere.
Please send me a link and allow me to download your copy of the firmware for the 7e. I would really appreciate if you could do this for me.
My email address is [email protected]
Hoping you would reply soon...
thanks,
Ariel(Reapjack)
Could you also sned me a link to the firmware. I received one yesterday, but its downloading the firmware at about 5% an hour for some reason! If I used this copy for firmware and put it on a micro sd and update the viewpad from that? Thanks in advance
My email is [email protected]
I pm the link to you for the update.
Reapjack - Not sure how you will install update. I would try to copy file to root of sd card and boot into recovery to see if it will install that way. If not rename it to update.zip to see if the recovery will work that way. Let us know know how it turns out and which way worked. Thanks.
I'm trying to download F70 VSAM_S_W_C_11282011.zip, but I have the same problem, the very slow download...
will you send me the firmware too?.
Thanks !

Update file ran but tablet keeps on rebooting..
Hi Andyav.. Thank you for the update file. The file ran as expected by putting it in the sdcard's root. The update went fine but my tablet still keeps on rebooting.
It seems that this update is overwriting only some files but not all. Maybe that part of the OS that was rooted earlier is not being overwritten. Would you know if there is a full update that will overwrite everyting?
Thank you again.... I appreciate the help so much!
Thanks Andyav !!!
I really appreciate your soon PM with the link.
I have problems with the spanish languaje, hope that this update fixt it.
I'll post the results.
Thanks again !

Reapjack - How did you apply the update. Through the recovery or through a normal boot? I know inside that update there is an updater-script for doing a full update, includes mbr, kernel, system...etc. I am not sure how to trigger it though. Maybe that’s what the boot flag is for in the recovery.
I did finally take the risk and adjust my density in the build.prop file. Tried a few different settings. Default is 180. I am currently running at 160 but did try 200 and 220. Looks good but the display is still not as clear as my phone (HTC Incredible running MIUI). I know the screens are not really comparable, but Viewsonic has been designing and building monitors for years and this is the best screen they could put in this tablet.
Also did some digging around on the internet about the host cable. Found a few here and there but I can be rather impatient at times, so I decided to make my own. Chopped off the end of an old Motorola house charger, shaved off al the plastic around the end, de-soldered the wires and one resistor from the small board. Then dismantled a usb cable I had made for my original Xbox, soldered the cable to the mini usb end, shorted pin 4 to pin 5, plugged her in with a keyboard attached and it worked, first try. I did notice that the host mode is not real reliable. After the initial test I could not get it recognize keyboard again. Checked all solder points, tested from usb female end to mini usb, all tested good. Several reboots with cable plugged in, nothing changed. I knows to go into host mode, I can see it switching when i run dmesg. But it just doesn't know what it attached to cable.
Andyav, i tot the lastest update is 20111125? I dont have the 28.... version for ota update.

After 12 hours of downloading, tried to upgrade from the internal application but after reboot, the process was canceled because it didn't find the .zip file on the sdcard. (error mounting sdcard)
Surely the problem was that the sdcard was not properly formatted.
Now,
the Recovery system shows 1.9 version and bootflag is only "1", regardless of the volume button I use to start (+ or -)
I formated the sdcard and tried to do a manual upgrade with the file downloaded directly from viewsonic: F70 VSAM_S_W_C_11282011.zip, but no luck, the recovery reported bad file.
Any help?
hellodzulz, will you tell me where did you dwonload the 20111125 update to try it

Over the last few days I have been trying to get the ready for custom roms when they become available. Digging around on the internet trying to find as much information as I could about the hardware. While digging around for devices that have custom roms and use the same processor line, I found some rather interesting information about the Galaxy S Unbrickable Mod. Basically it is a hardware mod that causes the phone to enter a Samsung download mode for flashing. Well I took the plunge and opened the case, found and verified the processor, broke out my multi-meter and went probing. Was able to locate the hardware that controls the boot sequence, preformed the mod and plugged it in to my linux box. Ran the Unbrickable Mod Mode Detector and it recognized it. HOLLY CRAP. I have to do a bit more research on utilizing this mod to our benefit but I an rather excited that this mod will work for us.
I've downloaded the file again and everything went ok.
May be the first download file was corrupted due to the slow transfer.
The errors that occurred when selecting Spanish language were resolved.
Anyway, there is an issue with bluetooth.
I can send files to other devices, but I cant receive with the VP7e, when I try to send some file, the VP7e don't show the popup window asking permission to receive file.
Is like it's denied by default.
Does somebody successfully tried to send/receive files with bluetooth ?
Thanks !

Tried to flash the wrong rom. now tablet wont turn on. when plugged into pc it comes up as m6 chip and i have no drivers. can anyone point me in the right direction.
Hello,
I suggest you to download AMLOGIC BURNING TOOL
this will also install the required drivers for M6 Chip .... but you have to find out correct files for using with it.

Revisiting this tab as my solution for having it work was to fling together parts of the nx008, not perfect, I still needed to get the original ROM.
Can you perhaps provide me with a dump of the original ROM?
Also if you need help loading the rom onto the bricked one, I believe I can be of some help.
Thanks
Hi fellow xda'rs,
I recently bought a Android TV Stick from Geek(app) from china.
I thought I had found a bargain as its specs were:-
2GB RAM
Quad Core CPU
16GB Storage
I managed to snap this up for £24 which I thought was a bargain but when I got the device delivered and was using it I thought it was a little on the slow side so I began to think it was a clone as its default OS theme was not the same as the usual CX919's aswell.
So I wanted to flash the device with a new ROM specifically the Finless 1.6b ROM.
So after following the instructions to installing the ROM using the software provided with the ROM download I managed to install the drivers and get the software to recognize the device. I then wiped the NAND and attempted to install the ROM but it failed .
Now the device does not boot at all and is not recognized by the PC. Windows just states the device is not recognized and has malfunctioned
So I cannot flash any other or what I believer I have found to be the original ROM for the clone device.
The board states its a GXT_D16_LP_V1.8 150310
I have seen that there are tutorials on putting the device into Mask Flash mode by shorting pins but as this is for the genuine CX919 my board is totally different and does not have the pins available to short I think.
In short could anyone help me to put this device into Mask Flash mode and tell me what id need to do and what pins to short please?
I have attached a couple of pictures of the device and board.

i found the mask flash mode pins to short by trial and error and luckily enough after 1 hour i solved it and got the pc to flash it back to its original rom. If anyone has the same device or issues and would like to know how to solve this i will be happy to help
I would be interested. I have a very similar clone (was supposed to be mk809iv). I have the same board although possibly different chipset.
I haven't bricked it (yet) but will probably do so if I can't find a way to root it. I think it may have come pre-rooted as super su was preinstalled but it has never worked (possibly because the app updated but not the binary?). I have since tried to update the binary and killed the root access completely.
Questions:
Is the ROM you used pre-rooted or rootable (if you've tried)?
Which pins need shorting? I have a button on the side that may be doing the same thing.
OT. How do I upload images or can I not as a new member?
Thanks in advance
any guide? i have the same device or where to download rom?
If your still looking, i might be able to help with a rom, root, and guide.
Thank you but managed to get root the same day you posted. I may still give it a go when my new tv box turns up though if you dont mind posting the info?
For anyone else interested in how I gained root:
1. Search for, download and install kingroot 4.6.5 (this is the version I used, only the latest version is available from official site and cannot be sure next steps will work with it)
2. Run kingroot and follow steps to gain root (dongle may reboot)
3. BUY super sume from play store.
4. Run super sume and follow steps to replace kingroot with super su.

Hello,
Having some problems with this stick .Messed up trying to flash a non rooted rom and now I only get a blue icon in rkbatch tool ( after short pin 5-6 ) and nothing happens. Download boot fail errors for a year...
Can someone help me please?
Is it the same model? What version of rkflash tool are you using. And what version are you trying to flash. In my case I didn't need to short any pins.

I've used several batchtools from 1.5 ( doesn't see my device at all ) to 1.8, different roms ( neomod, finless, stock cx919 roms )hoping one would give me something. All different bootloaders 1.24, 2.08, 2.13,...
I'm going to check mine out. It's been a minute since I used it. But I got the rock chip tool and the img file. I'll zip it up and pm you the link asap.

Hi folks, I'm hoping someone can help me unbrick my MXQ Pro 4k. I've searched high and low for the stock firmware but it is nowhere to be found. My box seems to be a peculiar variant and the specs are as follow:
S905x 1GB/8GB S905XQ_V2.0 2017.05.16
SV6051P Wifi
SK Hynix H27UCG812ETR DDR3
It became bricked when I tried to flash different atvXperience firmware img files with the Amlogic USB burn tool. I had successfully flashed it with a version posted by minixfreak on the freaktab forums.
Although not with exactly the same specs, it worked pretty well except for the remote control wouldn't function. So I tried to flash again with what I thought was the stock firmware but unfortunately, that bricked the box pretty good. I tried to revert to the atvXperience firmware that worked from the post, but it now always fails at 7% when trying to format with USB tool. In all cases, I've tried every possible combination of pushing in the reset button in the AV port, shorting the NAND pins, switching the order of USB ports... The box always has a red light when powered and is always recognized by the USB Burn Tool driver when connected to the OTG port on the box but always stops at 7% when it attempts to format.
I hooked up a serial usb/ttl cable to capture boot output, turned on the box and it seems the box is in an infinite loop with the following output:
LOOP:8F;EMMC:800;NAND:85;SD:800;USB:8;LOOP:90;EMMC :800;NAND:85;SD:800;USB:8. It appears the bootloader is corrupt or maybe has been erased.
I tried making a bootable sd card using both burncard maker and bootcard maker but that didn't work either as it can't get past intial boot attempt, even pressing reset or shorting nand pins. I'm not sure if it's because of the boot loop or perhaps incorrect firmware. I haven't been able to find the definitive stock firmware anywhere. I would appreciate help in finding this elusive firmware.
I've scoured the internet for a solution and tried many different things but nothing can get me out of this loop. I'm now at a dead end.
I once had a bricked router that I was able to fix by connecting usb/ttl and putty and repeatedly hitting Ctrl-C after rebooting to get a CFE prompt. At that point I was able to manually flash the router with firmware and revive it. Maybe there's a tool available that would possibly do something like that with the android box?
Also possible I guess that something in the hardware is toast and it's just a paper weight now. Anyway, any help and suggestions would be appreciated.
