Sharp Aquos S2 weird bootloop trouble with /persist partition - Android Q&A, Help & Troubleshooting

Hi.
I need some advice regarding bootloops on my Sharp Aquos S2. Device is unlocked and TWRP installed.
note: I have backup all of partition including modem1st etc.
Everytime i reflash ROM, it always bootloop. Bootloop will dissapear if i "fastboot erase persist" on download mode. Of course, side effect by deleting /persist, there will be no sensors working. Camera, wifi, fingerprint are not working.
What i did to fix:
1. dd if=sdcard/persist.img of=/dev/block/bootdevice/by-name/persist - still bootloop.
2. make_ext4fs and e2fcsk - still bootloop.
3. 9008 mode and emmcdl with firehose persist.img - still bootloop.
4. fastboot flash persist persist.img - still bootloop
5. using OST tools with nb0 image file - still bootloop
6. manual copy paste of extracted persist.img file via adb and root -
still bootloop
7. flash persist.img via twrp - still bootloop
8. Change sparse image to RAW command failed as persist.img already RAW.
9. Evertime i erased /persist with fastboot, device is booting but still with no sensors working.
Is there any way to fix /persist that probably i missed? As i discussed with @heineken78 it's probably hardware problem, but who knows it's just a partition or something that is not hardware related. Just wanna try my luck.
Any help would be greatly appreciated.
Thanks.

[Q] Lenovo P780 Boot loop help pls!

Hi all.
I guess I am in deep trouble.
I have a Lenovo P780 (chinese base rom) 4gb version. Rooted it and installed with CWM recovery for P780. Installed Muse UI 3.0 custom rom from custom recovery via sd card. Swapped the internal SD with External SD card by editing the vold.fstab and vold.fstab.nand also.
However, I realised that there are a lot of bloatwares that took up the RAM and started uninstalling chinese apps that seems to come with the custom rom from system. However, when I restarted the phone, its now unable to boot beyond the 1st boot screen. (Boot loop)
Current state of the phone now:
1. Able to enter custom recovery mode, but menu is blank except for the navigation commands. (return, up, down, confirm)
2. Able to enter adb only when the phone is in custom recovery mode.
3. Able to connect to PC (Windows 7 64bit). Mediatek MT6589 usb drivers installed. Many versions of sp flash tools installed and tried.
4. Can't seem to enter fastboot for this phone. (Tried many key combinations. Only Meta mode, recovery mode and factory mode are found)
Things I had tried:
1. Flashing stock rom.
I had downloaded the stock roms and tried flashing with sp flash tools, but I always encounter the following errors. Had also tried switching to another windows XP based pc and still encounter these errors.
(a) Firmware -> upgrade. Tried Auto Format Flash also and it returns with the same errors.
- BROM ERROR: S_FT_FORMAT_FAILED (4010)
Format flash error. Possibly given wrong format range. Please check your format settings.
(b) Download (all img boxes checked)
- BROM ERROR: S_FT_DOWNLOAD_FAIL (4008)
Download to flash fail!
(c) Download (only one img checkbox ticked, tried system.img and recovery.img)
- - BROM ERROR: S_FT_DOWNLOAD_FAIL (4008)
Download to flash fail!
2. Flashing recovery from adb terminal via windows and usb connection
When I put the phone to the custom recovery (with missing menu options), the adb terminal is able to recognise the phone and returns the following after the command 'adb devices':
0123456789ABCDEF recovery
Upon entering the shell via 'adb shell', I am given the # sign. (already in SU mode?)
Tried to flash a recovery image from this mode via terminal command flash_image, but encounters the following problems:
(a) unable to mount/remount
- mount -o remount rw /system
mount: mounting rw on /system failed: Invalid argument
chmod 777 /system/flash_image
# flash_image recovery /sdcard/recovery.img
no response from the terminal after this command.
I had tried and tried these for more than a week after work, but had not been successful in reviving this phone. Appreciate if anyone can assist me as I had ran out of ideas already.... Please assist me in reviving this good phone. Many Thanks!

Yep. Tried using several versions of the drivers downloaded from different places and used USBDeview to remove/reinstall them. The error still comes back and haunt me.
maybe this can help you
No luck.... formatting is not working in sp flash tool (4010 error) and the preloader in the thread is not for my phone.....
Anyone able to help pls....?

have you use google my brother ? google is our true friend.
but i glad if i can help you:angel:
you can visit this for factory rom
or you can visit lenovo forum
or you can go to needrom
Yeah. Google had been my fren, but no more after googling for 2 weeks without a solution. Trust me. I had looked thru most solutions found in google and had tried without any success before I post here.
All those stock roms of all release numbers I had already tried as mentioned above, with sp flash tools (tried many versions of that also.) ALL attempts are stucked with the errors mentioned above. The sp flashtool simply just fills the red status bar, and stopped with one of the errors in my 1st post.
I've even checked the chinese forums. My situation seems to be this:
The partition table of the flash memory had been reformatted thanks to the custom rom flashed via sd card. That's why it always returns a format flash error when I attempt to flash back to the stock rom which uses a different format range using sp flash tools. The only way out is to do a clean format of the flash memory. But I haven't find a way to do that via sp flash tool or mtk droid tool.
My only recourse is on of the following:
1. If I can restore the custom recovery (via adb in recovery mode(no fastboot) or meta mode) and make it workable to do another sd card flash with a custom rom. I have no idea why the options in my custom recovery went missing. It was working before I flashed the custom rom. I guess that accursed rom somehow erased my custom recovery during boot.
2. If I can somehow be able to do a complete flash format with the correct format parameters using some tools. Sp flash tools had failed me so far.
Anyone is able to help in these directions? Many thanks....
The sp flash tool log also have this line when I searched for 'Errors'
FlashTool[2684][8556][DEBUG]: ERROR: OperationIndicator::QueryDADLHint(): da_dl_type(??) error, could not find DA download hint!(.\OperationIndicator.cpp,98)

I think it's because the driver is not installed, try to disable digital signature on your windows, and reinstall driver for your phone
for how to disable digital signature go to this

Already tried this. I had tried on 2 pcs. Windows 7 and windows xp (no digital signature). Same errors occur in both pcs. I really don't know what is going on with this phone. Nothing seems to work.
PS: Have been running the program as administrator all along also.
Sent to a phone repair shop and its at worst state than before now. Unable to power on. Connecting phone to computer and tried using sp flashtool now gives 4032 error (Enable Dram failed).
Any hope with reviving this phone now?

Hi, first, do you have SP Flash Tool installed on your PC and have the drivers installed? If yes, download the stock ROM of your choice from here and flash it with via SP Flash Tool, and your phone should be revived.
Flashing methods are clearly stated in case if you don't know how to do it.

Need help ASUS W00YD recovery.img is missing

Hi,
I have a G500TG (ASUS_Z00YD) v12.0.0.38, 5..1 ,rooted, (Asus Live Phone) and need the recovery.img or some info about how to recreate/generate this img from these possible sources:
- the phone itself - it is not bricked but without the recovery mode I cant flash OTA files, zip or adb files;
- I did a backup before I done the procedure to install TWRP, flashed recovery.img, but no luck with TWRP working and now the recovery mode boot skips to Asus Logo screen, no more dead droidboot screen;
- The backup has (.backup extension) but no clue how to unzip it on PC to search for this file
- a firmware/rom from official Asus , but inside the zip file there is no recovery.img only boot.img
Checked previous thread "http://forum.xda-developers.com/android/help/asus-zenfone-zc500tg-root-request-t3282861/page7" but the recovery.img from this is for another model phone ZC500TG / Z00VD and as I discovered did not work with my phone.
Tried to reset to original configuration from phone but when it starts after the confirmation it boots to recovery mode cannot find recovery mode and boots back to phone.
Tried copying firmware zip on internal memory to force an OTA update but again without recovery mode, no luck.
So if I cannot restore the recovery.img it will be stuck until a big error occurs.
Ah I can access ADB and Fastboot commands from PC - Dont know how to rebuid recovery.img using SDK from Google...
Tried to use SPFlashTools but could not make MTK Preloader function in W7 tried various MTK drivers... I think all depends on that driver to solve this problem
Any helpful idea?
Thanks in advance

10€ who helps me solve this problem

Somehow I ****ed up my Oneplus One pretty badly.
I can't load in fastboot at all (either with pushing the vol+ key & power key nor with adb reboot-fastboot)
I already flashed the oneplus one recovery tool image and even tried the colouros image.
Nothing worked and I even can't adb push any file on my sdcard nor can I sideload any file to it (error can't find media)
every restart bring me directly to the recovery. (earlier i still had twrp running and tried wiping and flashing zips. even the stockroms didn't work. there was nothing else on the internal space but the gapps/rom zip files)
Isn't there a way I can force a complete image on my phone like I could on my Samsung with odin?
Did i accidently delete my boot partition?
How can I install the fastboot mode?
I will pay via paypal.

[Hisense A5] Deleted all partition table

Hello,
Cause of some problems (my Hisense enter test mode when charging), I've try re-installing firmware 6.03 from qfil method.
My problem is during the transfert, I had a power failure.
I don't know why but now my Hisense is empty of partitions.
I can not reboot, it stay in edl mode.
I was wondering if it's dead or if there is a way to recreate the partition table?
I have access to it in QFIL.
Thanks
Re-flash phone's Stock ROM.
The problem is too my knowledge, no official rom exist.
I has abble to recreate a partion table with emmc from firmware 6.03 (seems to be international rom).
So with qfil I've flash boot/vendor and recovery.
The problem is that my phone stay in edl mode.
I can't reboot to install firmware 6.09 from TF mode.
Disconnecting the battery don't change.
Edit: They are warnings when I upload files from eemcdl (PblHack: Error - 1836597052). I have to remove the battery after every operation.
emmcdl -gpt don't list any partition.
