[Sony Xperia E1] mai77:
【E1】 XPeria E1 (D2005) semi-official dev thread -flashing, hacking, rooting and all

E1 model long story short:

E1 facts:

- can be rooted (somewhat) easily -- see http://xdaforums.com/showpost.php?p=58056688&postcount=1307 for Kitkat 4.4.2 rooting with kernel-swapping via flashtool

- can be flashed, but not as versatile as GALAXYs with ODIN

- open source AOSP open source build 20.0.A.1.8 : http://developer.sonymobile.com/downloads/xperia-open-source-archives/open-source-archive-for-build-20-0-a-1-8/ (not "advertised" with other o.s. models... funny)

- FREEXPERIA support with few if any reports

- no full NANDROID support yet (fstab script not adapted)

conclusion: OK for developers. decrypt FTF poss. etc.

do a TA backup prior to unlocking bootloader else you kill your keys!

UPDATE: http://towelroot.com TOWELROOT will root "E1" as well as "E1 dual" UPDATE 2: but not the latest Oct.2014 version anymore. dang!

TIPS & TRICKS:

- if existent, kill youtube update apk. the update introduce nasty ad before each tube video

flash image: http://www.xperiadownload.cz/index.php/xperiadownload/category/49-e1# for Androxydes flash-tool --> http://androxyde.github.com/

The E1 has no hw back-button like other xperias. Instead flashmode and fastbootmode are entered into via POWER together with either of the VOLUME +/- keys - contrary to the ft's instructions (see pic above).

current Flashtool ver. 0-9-18-2 does have towelroot built-in it works if developer options are active (unknown sources , usb debug).

flashmode flashing works with ft and xperiaFIRM firmware files.

/ProgramData/Sony Mobile/Update Engine/db/13740270/blob_fs this is where PC-companion stores (win 8.1) the "4 SEUS files" for decoding with ft, e.g. FILE_280864415 containing the .sin files with the flash images.

#############################

open source build 20.0.A.1.8 : http://developer.sonymobile.com/dow...ves/open-source-archive-for-build-20-0-a-1-8/

that tool unlocks and relocks (advisable: do not change flasher installations in between) the bootloader (bl). so SONY's PC-companion does not complain and upgrades your E1 after you downgraded it with the Androxyde flasher.

these instructions http://xperiafirmware.com/8-firmware/48-sony-xperia-e1-dual-d2105

give you an idea about using Androxyde's ft.

The idea about SONYs "Emma" flash tool is to flash E1 with unlocked bl, which is sth. PC-companion and SUS will not do. (just relock with Androxyde ft, if u still can).

Emma does not support the E1 model, so it is useless for E1 users. No e-mail registration required, if you follow Sony instruction and put the .ini file from .zip next to the .exe file.

quick test to see whether your Windows drivers (version 1.5 or later) do work:

E1 win drivers come with Androxydes flash tool, plus you need ADK usb drivers and the SONY android_winusb.inf to manually place in adk subdirectory.

boot into fastbootmode - while USB plugged - and you must see a steady blue light on the phone's top (not green or red). if it goes off or is dark, probably your win driver has a yellow triangle to it because it malfunctions. to remedy: reinstall drivers after booting windows via (7)

advanced bootup

option (i.e. no enforcement of driver signatures). verify that the yellow triangle in windows device manager is gone.

1. power off E1

2. press and hold VOLUME UP button

3. plug in USB cable to Windows PC and E1 (both ends)

4. blue light must come on very soon

5. which indicates FAST BOOT MODE being active

stuff E1 users need:

rooted hot-bootable kernel

working TA-partn backup so users can unlock bootloaders late in the game

once you unlocked: it is no going back! (no relock method proven yet!)

to flash in flash-mode (rather than fast boot mode) u need to unlock the bl

TA (trim area) backup for relocking bl & save DRM keys: http://xdaforums.com/showthread.php?t=2292598

not yet tested for E1 - also you need root for it (no proven method for that yet).

best practise is to TA BACKUP your new E1 prior to unlocking - but as of now, the E1 is not yet supported by TA bak.

the TA-backup partition is helpful for possible relocking bootloader too.

there seems to be no way yet to keep the DRM certs on phone during full reflash, meaning all your payware is gone.

we need an aroma debloater to get rid of Megs of bloatware like chinese KBD (25MB) and such

rooting tool test results:

rooting with Androxyde tool = FAILURE

bin4ry v33 = FAILURE even with current adb.exe etc. (many error messages)

Framaroot = FAILURE

adb shell am start -n com.alephzain.framaroot/.FramaAdbActivity --es exploit Gandalf --ei action 0 = ERROR 5

so just use TOWELROOT, it works.

your directory

C:\ProgramData\Sony Mobile\Update Engine\db\13744270\blob_fs

(or likewise) has FILE_2809963345 asf. for A'xydes flash-tool SEUS-decrypt and to rebundle into bittorrent files and possibly even reflash this backup later.

safe mode: press+hold power while tap off (tap+hold 2 sec!)

--> reboot safe mode appears

flash mode : vol- plugin USB ..... no light

Androxyde's flashing is poss. only with unlocked bootoader (?)

fastbootmode : vol+ plugin USB .... blue steady light

unlike MTK phones, leave battery inside of E1 phone for reboot into flashmode

urban legend

: 3 vibes master reset via POWERup is not possible.

for SERVICE MENU dial this command: *#*#7378423#*#* i.e. * SERVICE #

UNLOCKING the E1 bootloader (not simlock or netlock): enter command

fastboot.exe -i 0x0fce oem unlock 0xKEY

, where KEY is the unlock boot loader key you got via mail by SONY after you gave them you IMEI and name asf.. (if you did...)

once unlocked, the SONY software will cease to update or reflash/repair the phone. use a proper flash-image and Androxyde flashtool instead.

(same with Galaxy: KIES will stop upgrading Galaxys after you used ODIN for manual flashing.)

#############################################

AOSP open source available for E1 via SONY see below ( seems, just 5 models (L, Z, S, ...) are advertised on SONY dev page, which is kind of misleading. Leads you to believe that there is no E1 source code.

open source build 20.0.A.1.8 : http://developer.sonymobile.com/dow...ves/open-source-archive-for-build-20-0-a-1-8/

no USB-to-go it seems

no flashlight

OS Android OS, v4.3 (Jelly Bean), planned upgrade to v4.4.2 (KitKat) anytime soon

Chipset Qualcomm MSM8210 Snapdragon 200

CPU Dual-core 1.2 GHz Cortex-A7

GPU Adreno 302 but no bravia engine advertised

Sensors Accelerometer, proximity, compass

Radio FM radio with RDS (spirit FM not working)

GPS Yes, with A-GPS support and GLONASS <-- but Glonass not in all markets

please tag all posts specific to E1 with a tag "E 1" or "E 1 dual" or "xperia E1"

################################################

When updating firmware (from jelly bean 4.2 -> 4.4), will it effect/update TA partition?

No. The TA partition is firmware-version-independent. (contains keys (DRM) etc.)

check the status of the DRM keys by entering *#*#SERVICE#*#* in the dialler, then looking in

Service tests - Security

All the keys should say [Key OK] if they're active. on my E1 I get "No data" (I have unlocked my bl). what is the display on a pristine E1 with locked bl?
