thanks for watching
Only if you still got into 1 of the bootloader menu ... for those who has stuck on the logo with no menu, i hope some genius will find away to reflash them (via jtag ???) someone notice the 4 dots between the CPU and battery connection? maybe it's a jtag, but event if it a jtag, i'm wondering if we have a App and files to flash it?
I like jtags also it was a fun hobby when i did it
he he he ... samsung galaxy tab (and some phone) do have jtag, check out sumsung to see how they do "full recovery" with jtag
i have riff jtag box. if i have pinouts i can re-flash it. well i dont have totally off xoom. bt if i have one i will make a jtag for you guys
new to this forum stuff but not to technology. Got a thinker here. Problem: impulse 4g u8800-51 has no hardware problems but will not power on. How it happend: i was in windows 7 doing a format of a USB HD when i formatted the whole phones HD. after format completed phone powered off. I've spent about a month trying everything i can. from lsusb in linux to trying using USB scanner / pc interface cable to get communication with the device with the computer. anybody have any ideas. cuz im just about start taking it apart to see what i can do with its parts but i'll check it out here first.
It seems like your EMMC card is wiped. The problem is that PBL on SOC wants to load DBL from EMMC (mmcblk0p3), and it doesn't exist so the device won't boot.
Currently, we have not discovered a way to restore from this kind of brick, so JTAG is probably the only way to do it at home. Who knows, there may be a way to restore from this brick but as said, no one has discovered it.
I dont know if this will helps but once I also did something stupid and formatted the partitions via CWM, (which is different from your case) so if you may power up your phone using the 2 volume + power button maybe this link will help you http://forum.xda-developers.com/showpost.php?p=23834865&postcount=6
jtag
ok im going to buy the jtag box to fix this phone which one should i buy?
So I was dumb enough to brick my OT 5038X by flashing boot image via fastboot. I'm gathering all the info I can and I'll be posting my progress here.
If you're looking for a root, just download mobogenie on PC, than KingRoot app on your phone. You'll be able to have SU in ROM Toolbox.
Here are some pictures, and what got my attention:
Is there any chance of unbricking my phone? I can't get any info on this, just a lot of people with the similar problems as me
Main problem we have here is that SP flash tool won't download. It reads back, but download is impossible, cause device disconnects when you try downloading. I tried without a battery, with a battery, with volume key down, with volume key up, and all possible hardkey combiations. I think that by soldering some of these soldering points together I can get it to work. I'll try measuring pins with multimeter for safety, so i don't burn something on my motherboard, I'll also try finding jtag pins that are in use. But I'll have to buy a "smarter" multimeter, so i dont get parallel port burnt, or phone mobo again. I have few multimeters, but all of them are cheap crappy chinese ones, and they don't read correctly.
According to MT6582 datasheet, there are 4 jtag pins, so there is just one unused pin. Hopefully I'll be able to write a program in C that will allow me to listen to the parallel port data so i can indentify which pins do what.

Hello, i have one small question. How did you flash the boot img through fastboot. I want the extact command. Also if you have adb then you isn't hard bricked because the adb-daemon boots with the kernel(bootimg).
Generally the jtag is for unbricking hard-bricked devices. You know with damaged bootloaders (IBL, SBL etc). And usually the points are close to the battery connector or behind the battery connector. And think these are your jtag point. There should be some GND points that's why you have 7 pins. You can identify which pins are GND with a multimeter.
And maybe is easy to unbrick your phone vio recovery mode. Have you tried to flash a full rom or a boot img?

I tried, but I don't have factory update, and my phone is running factory recovery. I know my phone isn't hardbricked, but I can't unbrick it, so JTAG is an option. I flashed bootimg with "fastboot flash boot boot.img"
OK... So I didnt miss being a idiot today again. Now I dont have ADB and recovery anymore. I flashed recovery with MTK droid tools generated image. But I did realize that it may be possible to unbrick this phone with SPFlash tool. This is the error I get:
Code:
06/07/2015 20:43:22.043 FlashTool[4772][2988][DEBUG]: NandLayoutParameter::CompareIsNandLayoutMatched(): NOT MATCH: load item key(RSV_OTP), value(0xffff0200), target item key(OTP), value(0xffff0200).(.\NandLayoutParameter.cpp,139)

First of all, jtag generally it's an expesive and a more difficult way to unbrick your phone. Also with jtag you don't flash the whole firmware. You only upload to the memory a bootloader which handles the update through sp flash tool let's say. And you flash your firmware.
Also if you find a factory pdate you can flash it through recovery. Was the boot.img faulty?
Boot image I used for flashing was for 5038D i think, there's not much of a difference between these two phones, but still it was enough to f*ck up my phone. I managed to get SP flash tools to the next level (luckily I have valid scatter file), but now I'm getting an error :
Anyway I want to find out where and what are the exact pins for JTAG, so I can help people who got hard bricked. It's not expensive if its possible to do it without extra tools. I hope i can do something by listening to paralell :/ I mentioned multimeter, I want to check if there's an power pin on jtag, so i dont get phone or parallel port burned.
Also there is no stock rom available for download, but there is source code on alcatel site.

I have done some research for jtag recently and usually you want a dev board to access the cpu of the phone. Maybe you can do it with the parallel but I'm not sure. With a dev board it's easier. Also we can make our dev board for jtaging and we can load on it openocd. It's a very good software fordebugging and jtaging.
Also there are many cheap boards in the web for example bus pirate (35$).
And there no Vcc pins or power pins in jtag. You power your phone from battery or from external power. There only TDI, TDO, TMS, TCK, TRST(optional).

Bus pirate seems like a great solution for me. Thanks for the info on JTAG. To be honest i didn't do any jtaging on "modern" phones. I did however jtaged xperia x1, and as i can remember there were VCC and GND, regardless of port you choose. Im also absolutely sure that one router i jtaged had power pins.
Anyway I managed to find POP D5 with stock firmware, so as soon as i get my hands on it Ill be writing a tutorial for soft bricked phones.

I'm happy to hear that you can unbrick your phone. But it would be nice to do some research how to jtag different phones. I know that it is difficult but as I understood your a hardware guy and you can solder wires to phones etc. So if you want I can help you to start a R&D thread with information...
Thanks for all the info. I'll order a bus pirate, regardless of this method I'll try with the parallel port. I definitely need one, cause I mess around with hardware a lot. I'm also willing to learn, so message me if you will with some interesting material. We can start a thread, why not. But let me do something concrete first.

you cannot find the stock firmware of this phone anywhere. if you bricked this phone you cannot unbricked it. none has ever unbrick this damn phone..... mine is just sitting in my cabinet still bricked untill now

What about Furious Gold? h t t p : // w w w .furiousgold . com /en/ module/ mtk-code-reader
The phone is not hardware-brick, but is lock by software. There got to be a way to bypass or pause the software for locking the USB port. I do not know if it could be possible but connecting the on-board memory to a USB adapter reader with the phone completely off. I am sure there is a way!
Managed to brick my shield somehow. I'm still able to enter the bootloader, but other than the nvidia logo keeps looping. The thing is I don't know if I flashed the right developer os. I choose the one which said 2015 Developer Pro because I've read the 2017 pro is the excactly same as the 2015 pro, is this true? I used the nvidia controller's usb a/micro-b cable, which I think isn't enough as it gave me a lot of errors at the start but then worked until i flashed the system img which stopped at step 7. I'll order order another a/a cable instead and try, as I've read through the forum and found that the cable can be the issue, but maybe someone can enlighten me more. Thanks in advance!
So I got it working again, to answer my own questions for you.
1. The 2015 pro (500gb) and the 2017 pro (500gb) uses the same images.
2. The cable wasn't the issue, I think the Shields usb ports have been worn out (seems to be an issue others have experienced aswell) hence the random disconnects while flashing.
Solution:
I managed to boot into twrp without losing usb connection (fastboot boot twrp.img), and from there I flashed the developer os.
