Hardbricked LE Max 2 x829, last try before throwing it away! - LeEco Le Max 2 Questions & Answers

Hello
Seems like my LeMax2 is hardbricked.
Current Situation
Mobile starts with double vibrate, loads splash screen, waits for like 10 second and restarts again.
I can only enter into fastboot mode and QIFL Download mode.
What I have tried already with no success
QIFL Fastone restore
Full format with all partition tables
Installed almost all roms available via fastboot
Installed almost all recoveries but if entering into recovery it only shows splash of recovery with Leeco logo and restarts again.
Discharged mobile for a day
Kept it charging for a day
One of expert from XDA also helped with Teamweaver for almost 4 hours but no success.
I have been told the last thing I can try is if someone can give me a full diskdump of their own working LeMax2 829 preferably stock then it may work, this is the last thing I want to spend my time on before throwing it away and buying a new phone, my own guess is that partition table is corrupted or rom have bad sector so if anyone can help please I will be extremely thankful.

you have tried to unbrick with qfil service rom like it is described here:
https://www.gizmochina.com/2016/11/20/leeco-x820-max-2-super-unbrick-guide/
???
I had the same situation and it worked for me!

He tried everything, really! This is stuff for an expert or anyone who run into the same Problem and was able to fix it. Maybe writing a full dd image (meanig really everything, not only some files|partitions) will do it. imei and mac adresses will be blanked of course. This is not about pulling files or partitions, its dumping the whole flash content to one file!
So: DD image needed badly, best same model, untinkered.
Another question:
Can somebody tell how to recreate the partition table properly? i mean not erasing content or formatting - recreating|repartitioning.
I know how it works on Samsung but it's totally different.
My thoughts are:
-Messed up partition table
-flash either physically defective or somehow Locked for read-only
-other Hardware/Software fault
I already threw one x829 away which had almost the same Problem.
I bet there will be more threads about malfunctioning x829 soon...

@craftvision, i have 1 (strange) idea. Today i received my spare x2 and while tinkering with the device, i made something stoopid wich could be of use...
Fixed it in 1 minute again but was surprised it worked...
Of course, chances are low...

has spent his more than 8 hours of his personal time with me on Teamweaver, he is really a good helpful guy and a real Android expert, big thanks to him for all his time.
Phone is still in same condition, only loads splash for 10 seconds and restarts and enters only in QFIL Download or Fastboot mood, all installations are still successful, seeings new Splash screens with every rom that I could install via fast but but boot loop and no recovery.

Happened to me with a Oneplus One. Rarely it booted but it had random reboots on every rom from minute to minute. My guess is that something is fuc*ed up inside the phone. Never found a solution, just bought a new motherboard. My guess was that the EMMC or something broke

Instead of throwing it away, please send it to me, pay your shipping ......

I was going to say the same thing here do not throw it away, I own a x829 for about one week and love this thing.

Yes, try replacing the whole memory block. That would be the best way to rule out hardware fault.

I think we cannot even buy only memory block, I guess I have to buy complete mother board, and so far I could not even find a complete motherboard set online anywhere.

theese bga's are not easy to exhange. best would be an infrared reworkstation with ir preheater. if you aren't familiar with bga reballing, i think the chance you get it right is under 1%.
i have a cheap hot-air solder station, self made preheater, ir-thermometer, thermo-couple and lot of required tools. the equipment is sufficient to do simple reflows on xbox, playstation, whatever electronics... however, this is not a professional fix and not sufficient to do bga reballings. you need to follow a temperature curve, it's tricky (for me at least). you can try to put it in the oven with no-clean flux but chances are high you will ruin it. plastic melts easily, capacitors tend to "popcorn" when too much/too long heat is apllied.

Is there a way to convert a Recovery rom to a fastboot rom?
I tried this method
http://www.droidviews.com/convert-and-extract-system-img-and-system-new-dat-files-on-windows/
That converted system.new.dat to system.img but while flash it gives this error "Invalid sparse file format at header magi" and then fastboot command crashes..!
I want to convert CN26 flash able via fastboot because it was most successful rom for me so far!

No I didn't mean that you should buy emmc(the flash storage) or the motherboard. I meant the whole partition dump of a working device. I won't be able to find a le max 2, but I can help you with the flashing. The header sparse thing means it needs to be in sparse chunks or even the sparse header at the top of the image file. The file is bigger than what your device supports, so it will send it out in chunks. Sometimes it automatically starts after waiting for a few minutes. It would be much easier to just flash it by TWRP. Have you tried flashing recovery partition or directly booting to twrp from the fastboot bootloader screen?

Yes, have tried flashing all recoveries available in recovery partition or even in boot partition. A.N.Driod has also flashed his own x829 diskdump on my phone but no success.
Only fastboot and QIFL Download is available at this phone...

Are you able to boot into some image through fastboot? Like, "fastboot boot recovery.img"

no, flash is success but loads only splash of recovery, waits for 10 seconds and reboots again. Have tried all versions of TWRP available

Don't flash recovery, you can directly boot from the fastboot screen. Instead of "fastboot flash recovery twrprecovery.img" do "fastboot boot twrprecovery.img".

That too negative, it loads normal splash and then restarts

And you have tried flashing stock sparse images with qfil?

There is probably a hardware problem with the device. The internal storage should be ok as the qfil flashing should fail and the device would not boot in any way if that was the case.
If you have successfully flashed through qfil, there is no reason for a boot problem...

Btw, the above link you provided is for x820 which is 32 gb version, i think. X829 is 64 gb, maybe try this? https://forum.xda-developers.com/le-max-2/how-to/official-fastboot-rom-x829-regular-twrp-t3620591
