Note where talking about the single SIM desire 620 Qualcomm snapdragon 410 not the 620g which has different cpu and uses different firmware

desire620a31ul_stock_recovery
Taken from Orange UK rom, as far as I know recoveries are not carrier specific.

https://docs.google.com/file/d/0Bw7S-kfd-L-RdFVwY3FGaHkyaG8/edit?usp=docslist_api

This could be used to compile a custom recovery either TWRP or clockworkmod.

Next is the boot loader Rom for the UK orange carrier. This also contains the stock recovery.

Reading online about creating custom recovery its seems the stock boot image is usually used to building programs that MediaTek devices which the 620 in question isn't, so i've uploaded it from the RUU files.
The closest desire to the 620 A31UL that has a custom recovery is the Desire 816 which has a Qualcomm MSM8928 Snapdragon 400 chip set, the 620 A31Ul has a Qualcomm MSM8916 Snapdragon 410, both of these are Kitkat phones.

What we need is someone with experience in creating recoveries and experience in the Linux environment, we can provide all the needed files and flash any created recovery for testing. And then if this recovery works successfully that could post it to TWRP or CWM for regular android users.
I've had two prevous phones Xperia Ray and Galaxy S3 both which i rooted uses sources built by others and install many different customs roms. So if someone was able to create a recovery we easily be able to test it.

Just uploaded HTC desire 620 A31UL stock firmware
These are for the EE/ORANGE carrier UK only and are here if you have bricked your device.

RUU file is for Windows and from my understanding you need to first re-lock your bootloader.

RUU_A31_UL_K44_DESIRE_Orange_UK_1.02.61.1_Radio_00.03.012_U10012131_41.09.1225_release_413623_signed.exe

https://docs.google.com/file/d/0Bw7S-kfd-L-RbEE4RnBjcmg1UkE/edit?usp=docslist_api

This is to flash stock firmware without pc, rename the file to 0PE6IMG.zip and copy to the root of sd card. When in hboot boot loader it should flash. Or you could flash in stock recovery.

All files are from www.ir-file.com

7alizani has come across this
CarlivImageKitchen-Windows_v1.0.zip tool for unpacking/repacking boot and recovery images for Android phones:*Carliv Image Kitchen for Android.

https://docs.google.com/file/d/0Bw7S-kfd-L-RVDRieUNHV19NUE0/edit?usp=docslist_api

Using this u can extract the recovery.fstab file from the recovery.img

Recovery_fstab_from_desire620A31UL.rar

https://docs.google.com/file/d/0Bw7S-kfd-L-RQS1rQ2ZQMGtDY3c/edit?usp=docslist_api

The complete set of files extracted

https://docs.google.com/file/d/0Bw7S-kfd-L-RbWt2ZHFfdFNBQ28/edit?usp=docslist_api

The next step would be to create the custom recovery from this which we need some assistance from someone experienced in building recoveries.

We have had a break through S.Yazdanfar at ir-file has sent me a custom recovery via email, will test this later today and try to root through installing superuser.zip. Will post the results and recovery if it is sucessfull

 

[7alizani]

I successfully flashed recovery.img from fastboot, but when I tried to open recovery in less than a sec gives me this message

, after that recovery in hboot menu disappeared.

I repeat whole steps, with clearing cache in fastboot after flashing recovery getting this:

, and automatically revert to hboot...

 

[baxter006]

What did u use to flash it? Did u reflash the stock recovery back

 

[7alizani]

What did u use to flash it? Did u reflash the stock recovery back

No, phone boots fine with custom recovery... unable to enter recovery

 

[baxter006]

Damn was expecting it to be fine, u don't have to press power and volume to get into recovery?

 

[7alizani]

Damn was expecting it to be fine, u don't have to press power and volume to get into recovery?

no, I chose it from hboot menu and after pressing power button in less than a sec I got message from the picture above Entering recovery...

 

[baxter006]

I mean when in that screen u don't have to press a combination to get in recovery. I've never had a HTC before. I'm at work for another hour so can't try. What u use to flash the img?
