recover deleted data from HTC M8

[bigjay88]

Hi Guys,

so I have deleted some data from HTC m8 and looking to recover it.

if I formated my phone, will it still possible to recover it ? and how please

Most phones do an automatic back-up on a set regular basis, which will be stored online usually on the phone makers web site ( you set this up when you take the phone out of the box and set it up for first use ).
If you did this you would be able to retrieve the data by downloading the back-up to the phone again.
If your phone has not done a back-up then i'm afraid you will have lost the data, especially so if you do a format of the phone.

someone asked for 100 $ and he said he can recover all, is that possible ?

[AirShowNut]

Usually a format over writes the entire storage space with random digits.
As far as i know only high end recovery software similar to that used by law enforcement and government departments have the ability to recover data.
If this person does have such software, ask him what it's called and research it before committing to anything, having said that 100$ seems a bit steep to pay for such a service. But the choice is yours, is the data worth the cost of recovery and does the cost outweigh the value of the phone ?

high end recovery software??? cmon
If it's in working condition it's easy. Custom recovery and make full backup from the userdata partition. After you have the raw binare let's run a simple free Testdisk one time i recovered a dead samsung over a thousand picture (mostly thumbnails but who cares)
If it non working , open the phone and ISP read the emmc with a 100usd box and you get the whole /userdata too. Unless it's emmc damaged (BTW crappy Hynix mostly )

If it's in working condition it's easy ?????? CMON !!!!!!!!

If the phone was formatted all partitions in the internal memory will have been erased, not just written over like in a HDD. Flash memory is spiked by the electronics in the phone to permanently erase all data from it, the same goes for SSD's as well !

You don't have the knowledge or/and the tools. I'm in the gsm business since '97. It's easy

So why no offer to do the job for bigjay88 ?

Bcose unlike you i read the forum rules Advertizing is forbidden mate and i don't want to be banned.
If you want something besides the weak roasting attempts just ask. I will help you openly here. For free

[AirShowNut]

IF you were to "offer" to help that could never be classed as advertising.
But then if you read the rules correctly you would have realised that.

Return to the orig topic:

HTC M8 userdata dumping:
When the product is HTC M8_UL (most common in europe modelid: 0P6B10000)

after root (perm or temp) or under custom reco

adb.exe
adb shell
su 
(if granted)
dd if=/dev/block/mmcblk0p47 of=/external_sd/userdata.bin

where the external_sd path is depends the actual sw version could be sdcard2, external_sd, sdcard1..etc you must check before the operation.
Use large storage, high speed sd card like 32 gb SDHC

This operation will dump the whole userdata partiotion bit per bit to the sd card. And yes even copy the deleted files.
For the best performace use a linux machine but working on any mS op. too. Run the run the testdisk and enjoy the result. For free.

"only high end recovery software" my ass

How are people supposed to understand the process needed in order to recover their phone when no instructions were supplied ?
It's alright giving the info but people need instructions step by step too.
Also i don't know what a "partiotion" is ?

Those are the step-by-step instructions.
Without the very basic knowledge like linux commands, file systems (like partitions) MS, linux, android bridge shell..etc you can archive one thing. To permamently kill your phone.
