Hard bricked Xperia M - Help!

Hello all, I have been a lurker for quite a while here. I own an Xperia M (Rooted, Unlocked BL running CM11). I was feeling adventurous and started messing with the partition table hoping to resize the system and data partitions using parted. I was unaware that the bootloader detects such modifications and ended up with a brick.
Just to clarify, this is a hard brick, since the Flashtool and fastboot modes do not work. I do not see the blue LED while trying to start the device in the fastboot mode using the volume rockers. My PC only detects a "QHSUSB_DLOAD" device for which I've installed the drivers and it is now "Qualcomm HS-UDB QDLoader 9008".
However, before I started to work with the partition table, I took a raw backup of the emmc i.e. mmcblk0. This should include the correct partition table and all the partitions (TA, userdata, system etc.). Theoretically (I believe so), if this is reflashed onto the device, an unbrick could be possible. However, so far, I haven't been able to figure out a way to push this image back to the device. I came across QPST and some linux bash scripts but haven't been able to use them successfully.
Has anyone come across such a scenario before? I looked for solutions in other threads but didn't find anything conclusive for Xperia devices. Can someone help me with this? thanks.

Hi,
On other forum one user followed suggested by me same theory of remapping paritions as described here to shrink so large /system and increase /userdata
He gotta same brick because deleted 3 partitions and then they was cannot created by any commands, so seems this method not applicable to our phone.
Next he very early quited from recovery without restoring partition table from backup.
Surprisingly, in un-offical service center phone was quickly fixed, seems with JTAG-device.
QHSUSB_DLOAD – this is fall-back low-level mode of CPU that allow access to all partitions just like fastboot
Needed to repair / writing stock ROM at factory.
Can be enabled manually by connecting to PC with holding both volume buttons. How to exit – don't know.
QPST utility not useful because we not have dump in it's proper format. So only Linux our hope.
That user tried to manage with Ubuntu but phone was not recognized. Very likely he went into something wrong.
That's very great that you created backup of whole NAND.
Maybe will be enough restore GPT (partition table), I have one and own per-partitions dump too.
So plan very easy: connecting phone to PC with Ubuntu and restore dump via dd utility.
Partially follow this instruction with modifications because you have full dump.
Connect phone, find where it "attached" (whole nand, not partitions), restore file there.
Be careful with disk naming, you can damage data on HDD.

Hi Bonoboo, thank you for replying.
Unfortunately, Ubuntu isn't able to detect the emmc and therefore, I'm unable to find the "/dev/sdX" node for the device. The phone is being detected only as "Qualcomm, Inc. Gobi Wireless Modem (QDL mode)".
I've seen some threads wherein QPST is first used to enable the partitions detection of emmc. However, as you mentioned, we do not have the necessary MSM8227 HEX file for this.
A windows app called "s1tool.exe" can be used to flash the bootloader files from the FTF, Link to thread. However, a testpoint combination is needed to access the emergency mode. I was unable to find a testpoint for Xperia M.
Is JTAG the only way forward here? Thanks again for the help.
EDIT: Looks like the s1tool I mentioned is device specific, may not work with XM.

Yeah, this is not good, same as was with that guy. 1, 2
But here under spoiler I found Perl-script that may open access to eMMC.
Here more info.
Maybe it device-specific too, but anyway try.
UPD: post
just connect your phone to PC (at this time your /var/log/kern.log should update and ttyUSB0 should be added), in terminal, cd to your download folder and run './qd.pl --check', or run 'perl ./qd.pl --check'.

Hello Bonoboo,
I've tried using the qd.pl script but I'm not sure which file needs to be sent to the device when using the "qd.pl --pfile X" and the other parameters. The script detects the Qualcomm modem. I've tried uploading the first 256 kilobytes of the dump which should include the partition table but this results in an "Invalid Response" error from the script. Tried uploading the TA and some other partitions, but received the same error. No eMMC access yet. What file do you think the script requires?

Was mentioned some *.hex, that maybe relates with same from QPST.
In threads more info.
Very likely script just not compatible with M.
UPD: it's sounds weird, but try to connect phone in fastboot / flashmode with long holding volume key.
In some cases this really helpful due second "bootloader" (alt_s1sbl2 partition and other).

Hi, I tried long-pressing the volume key, it does not seem to work. Thanks for the confirmation about the hex file. It looks like I'll need the right files for the handset, as using hex files of similar chipsets did not help. I'll keep working on it and write back with an update if I'm able to fix it.

I've got the same problem., but unfortunately I didn't make a dump of mmcblk0. There is a way I can get yours? Or a part of it with the interesting data with which I can try figuring out how the qdload.pl script works (maybe leave out userdata cause of its size and the private data).

Hi fakier, sorry to know you have the same problem. I've sent you a PM with a link to a compressed copy of the first 140 MBs of the raw eMMC dump I made earlier. This should contain all the important partitions besides system and userdata. Note that this also includes my TA partition which probably shouldn't be written to your device.

Update
Hello folks, after spending a lot of time trying to fix my device with qdloader and QPST, I gave up. Before getting it JTAGed, I wanted to try my luck (again) and approached Sony to claim warranty, since there was a month remaining before its expiry.
My warranty claim was accepted and they replaced the mainboard, though the bootloader was unlocked!! My Xperia is alive and kicking again! Will unlock it soon.
Trying to fix the phone was not a pleasant experience, but I think I learned much along the way. Hope nobody else screws-up the way I did.
Thanks XDA, see ya around! :good:

Dude what was the point of this thread and when you tried to fix your phone did you re flash stock ROM?

The point of this thread, dude, was to see if the device could somehow be taken out of the "Qualcomm HS-USB QDLoader 9008" mode, a (very) low-level interface meant for vendors to flash bootloaders and system images on their devices.
..and when you tried to fix your phone did you re flash stock ROM?
Click to expand...

Had you googled this, you'd know that this mode isn't the same as the Flashtool flash mode or fastboot. No rom, stock or CM, can be flashed before fixing the bootloader itself, which is needed to start the device.
Not much progress could be made here since the bootloader hex files for Qualcomm's OEM tools (QPST) would be needed to fix such a hard brick. Also, the QDloader scripts mentioned earlier were written for a different chipset from the one used in Xperia M.
Cheers, RS.

[Q] Urgent simple question regarding S8500

Hey,
I've got a friend that has a s8500, the screen broke and i changed it. By the time i gave it back to him he had forgotten the Phone Securty code he had setup. The only thing i want is a way to recover the data before the reset.
Is there any way to achieve that? Or is there any way to reset/get the code ? I've been looking into the FLOCK thread but im afraid it will lose the data after the flash.
We also contacted Samsung and they said the only way to reset that code is with a hard reset which will make the data being lost.
Can i in recovery/download mode get the data? The most important thing is the contacts/photos.
Thanks in advance.

No idea about the FLOCK thing, i think it's to unlock SIM-LOCK or freeze and not the phone.
The photo are recoverable with android, not sure about the contact (i don't know where they are stored in bada).
In short, you need to boot an android recovery (see the android dev on bada section, i can also provide more detailled instructions), mount bada user partition and then copy paste what's inside on SDcard.
It need an sdcard, a SD fota, multiloader an android kernel and adb (android debug bridge, free software anywhere on the net).
No data will be lost if you do it (if you are on bada 2, else i don't know, and phone will still be locked).

Thank you, i had forgotten that i could just boot a costum recovery. Need to do some research on the contacts location tho since it's really the most important data i need to recover. Thank you again.

[Q] How do I restore system partitions?

Basically, I accidentally deleted the first 5 system partitions which bricked my phone. I found a system dump which is the same version as the ROM I was using on my phone. I haven't downloaded it yet, but, I believe, system dumps contain all the system partitions which are in img file format (not sure on this). My phone does get detected on my computer as QHSUSB_BULK but not with adb, so if I could get my phone into fastboot mode and hopefully my computer detects my phone in fastboot mode, will it be possible to flash the system partition imgs and restore my phone?
nb: my phone won't turn on; I don't know if it charges as there's no charging Led but sometimes if I plug it in to charge it flashes on then stays off; can't get into recovery; phone doesn't seem to respond to combination presses but I have yet to try this method
When you plug it into the computer does the computer make a ding sound that it's connected? If so, then press power and volume up until the disconnect ding sound which indicates it's rebooting and then immediately press volume down and see if you can get into fastboot. The timing is tricky so I've found using audio cues from computer can help if the phone is messed up.

Quick answer, you can't AFAIK. Not without a JTAG box

I think by "system partition" you mean "partition". There is the actual /system partition, and deleting that will only have wiped the ROM. I think you actually deleted other partitions; in particular if you wiped hboot or radio, the phone is screwed and you need JTAG.
QHSUSB_BULK (or similar) message when connecting to computer, and screen not coming on at all, reinforces that notion.

So my best bet is it send it to a HTC certified repair centre and get them to fix it? If that's the case, how long does it usually take and what's the average cost?

According to the list you linked, you deleted a bootloader module (sbl1). So its a real brick.

That would certainly work. HTC will probably replace the motherboard, which if memory serves me (based on reports by others here) is something like $300 US.
But it may be cheaper to find a repair shop that can JTAG the phone. I think that price is around $100-150. But you need to find a shop that can do it, and on the M8 specifically.

Lenovo MOTO Smart Assistant (LMSA) - Recovery, Rescue, Update, Backup, Restore, Clone

I just wanted to point up the Lenovo Moto Smart Assistant (LMSA). This is a PC program. When you plug your phone into the PC with a USB cable, you can update your phone to the latest available version, recover & rescue from various problems, backup & restore, clone all the information/programs to a new phone, and a few more helpful things.
Download LMSA here
LMSA Documentation/Help here
In addition, it will do a bunch of utility type things, like making ringtones, transferring files, etc.
Just for example, when I managed to to horch up my phone by switching to Partition B in TWRP (DON'T do that), I did the blankflash thing from here, then used LMSA to restore the system. (I'm not sure if LMSA could recover from a hard brick--it might, but I didn't try it.)
Also I was stuck on the March 2019 security update and used LMSA to upgrade to the latest available security update.
Point is, based on lots of threads I see here, it seems that many people don't know about LMSA.
If you're on the stock ROM (even rooted) it might be quite a bit easier to do certain system functions, like update, rescue, and backup, via LMSA than other methods. Even if you're on a custom ROM LMSA might still be helpful in certain situations.

thx but...

Redmi Note 8 locked, need help with unlocking/backup

Hello!
I need help regarding a Redmi Note 8 that no longer accepts the correct pattern and is locked.
I'm looking for a solution that would allow me to either unlock my phone without data loss, or make a backup of the phone's internal storage on an sd card/pc before hard resetting.
The device is not rooted and I don't have custom recovery installed. USB Debugging is on, but my laptop is not authorized.
With Adb, the device is detected but unauthorized. It seems to be detected normally in fastboot mode. I was able to get my laptop to detect it in recovery mode by clicking on "Connect with MIAssistant" while it was plugged in, but only in sideload mode. I also somehow managed to get into safe mode, but I used the stock screen lock, so unless there's something else that can be done in that mode, it doesn't seem useful in this situation.
I tried the actual MIAssistant software but it tells me to update my device before connecting. From what I found, this is because it doesn't even work with phones running Android 6.0 Marshmallow or above, so that seems to be a dead-end, unfortunately. Downloaded from here, updated to version 3.2.1.3111. If there's a newer version that could support my device, even an untranslated one, I would love to know, but I couldn't find a working one.
I had some ideas that could potentially solve my problem, but couldn't find a way to actually execute them, so here they are in case someone out there who knows more than me could help me with one of them.
1, Is there any way I could authorize my laptop for USB Debugging without being able to accept the prompt on screen?
2, Is there a way to make a backup of the internal storage of my phone in fastboot/sideload mode?
3, Is there a way to get adb to detect this device normally in recovery mode, instead of in sideload mode?
4, Is there a way to get my device into mtp/ptp mode instead of charging mode when connected to a PC without USB Debugging so I can copy my files?
5, Here's a thread I found that seems promising, although it's old. Could I somehow use this, or a similar method on Redmi Note 8? The Recovery Mode is much more limiting on this device, unfortunately, so I can't exactly follow this tutorial. Are there alternatives that can be done in adb fastboot/sideload mode, perhaps?
6, If I am forced to hard reset, is there any software out there that could recover at least some of the deleted data afterwards, or is everything lost in case of a reset?
I am open to new ideas not listed above, as well. I am not a very advanced user so I probably missed some things.
Thank you so much for any answer in advance!

Even if you can copy your files to PC, they are problably unusable because of encryption.
That is why you need that pattern
For security this is exactly what you want, if your phone is lost or stolen.

Do you mean that the reason it doesn't accept the correct pattern anymore is for security? I would have thought it would still accept the correct one, at least after several tries of the same thing. Being completely locked out even when you know the correct password is a little strange to me.
