I have a BT338 bluetooth GPS adapter it will not get a lock on and I have been looking for a flash program for it to see if I can reflash it.
I followed a link from a site to this sites ftp server that used to have it but it looks like it has been taken down.
Does anyone know if flashing is possible and if so does anyone have a program to do so?
Thanks for any help.
Packrat,
I have had a BT-338 for two years and I love it. I don't recall that I was ever able to find a method to upgrade the firmware. I will watch this thread in case some one has an answer.
On the other hand, I did have problems when I first got this unit. If I played with changing setting between WAAS/normal and/or Sirf/NMEA modes, sometimes this thing was not get a lock. To fix it I would use a laptop tool to reset the unit to factor setting. I think it was GPSInfo connecting via a BT dongle.
Let me know if this might help and I will look into the exact detail if you need it.

Thanks for the reply, I tried to reset it to factory via the SirDemo program, but that didnt help. Hopefully I can find a way.
Yes reflash is possible...
You can use SirfDemo and SirfFlash
The procedure is almost the one described here....
http://web.mac.com/tomtastic/site/log/Entries/2007/6/18_Holux_GPSlim236_boot_mode.html
You can download the needed tools here...
http://www.falcom.de/support/software-tools/sirf/
To flash
- First you have to connect your bt-338 using SirfDemo.
- In Action/ Transmit Serial Message select NMEA and send this message
'PSRF100,0,38400,8,1,0' without quotes. This will put the GPS in SIRF Mode.
- After that choose Action / Transmit Serial Message select SIRF this time and send '94' without quotes. This will put the GPS in boot Mode.
- Disconnect now SirfDemo using the button and start SirfFlash without powering down the GPS.
- Choose the correct port and 38400 Baud and - very important -select 'external boot mode'. Browse for the new firmware .bin file and select 'program flash'.
- Execute and enjoy.
Cheers!
I have now (finally!) successfully read the firmware from my two BT338 and a TomTom Mk2 BT mouse. Also important to notice is the following:
- Address Range is 0x0 to 0x7ffff (4 times an "f") resulting in a 512kB bin file.
- Any other speed than 38400 will NOT work!
Did not dare yet to flash actually... I have now:
TomTom Mk-II
GSW3.0.2TomTom1.1_3.0.00.03-C3P1.02b
BT338 (NaviLock labled in Germany)
GSW3.0.2_3.0.00.03-C16P1.02a
GSW3.1.1LowV_3.1.00.07-C23B1.00
I know there must be newer one for BT338 as you can see from the FAQ at Globalsat USA at: http://www.usglobalsat.com/gpsfacts/bt338_gps_facts.html
The mention even different versions there (QA 38):
BT-338_GSW3V3.1.1LowV_F-GPS-03-0506222 and
BT-338_GSW3.1.1TO_F-GPS-03-0510032
I noticed that reading out the SW sometimes delivers different results after 7d008 when some time has passed. I suspect that some data is stored there which may vary over time (satelite positions, routes or whatever may be stored depending on the time).

I can report success now in upgrading my BT338 from the old (3.0.2) FW to the later one (3.1.1) I have retrieved from my other BT338.
Main gain for me is the availability of geoid correction for the height.
Anynone has a later firmware for the BT338 or the TomTom MK2?
You can PM me if you don't want to post here.

Hi tobbie,
have you managed to get some new firmwares , I am searching if there is a new one for the tomtom ( there is still some issues between the treo and the tomtom related to the bluetooth stack ). Is there a way to use the BT-338 or a part of the BT-338 firmware in the tomtom ?
thanks
Laurent
look here: http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=27925&whichpage=11
please read all posts and follow the wohle story. My TomTom MkII currently runs the 3.2.2 of the latest BT338.
Thanks tobbie,
I have red the full thread, downloaded your dumps of the firmware, and dump my tomtom firmwarewith the sirf tools.
I have compared the dump from your tomtom and mine ( same version 302 ) and they are quite different beiginning in 6D008 :
your firmware :
6D008 : 06 3E 00 00 01 00 00 00 41 46 31 41 39 53 D8 19 ....
my dump :
6D008 : 20 C6 00 00 99 00 00 00 41 46 31 41 39 53 D8 19 ....
Is this part a variable part ( so may be a factory reset and a new dump will give a more comparable result ), or is there a real difference for two same version of the firmware ??
Can you tell me for upgrading the firmware of the tomtom have you used the full 3.11 firmware from 0 to 7FFFF or have you used a dump from 0 to 79999 ?
seeing the various problems some got after flashing their units I am a bit worried before flashing mine..
thanks
Laurent
Just do a system reset of your device and dump it again.
Depending how fast you are getting it into bootmode you have some data there (and not all default empty data). Doing the same after some time (e.g. after a fix was established) will again deliver different data there.
I think the main thing here is that the WHOLE data are dumped and then later flashed to another device. This may also be the rootcause of the failure to use the 0-79999 dump - where after 79999 data may confuse the device to get back online (very sad - it already cost 2 devices one BT338 and one TomTom MkII).
I have used my own dumps to crossupgrade from BT338 to TomTom and the 3.2.2 from antineutrino. After some back and forth I am on 3.2.2 again currently for all devices (living with the green-LED off until a fix).
BTW: I am quite sure that the bluetooth part is not touched by these updates.
The names of the devices as they are recognized on bluetooth are not changing after a FW update.
thanks tobbie ,
as I need this gps in the coming next weeks, I will not take the chance to do the upgrade just now. I will wait a quiter period of time to try it ( so if I brick it I will have time to make a replacement ).
thanks, I will come back for detailled instructions in some weeks.
Laurent
Hi Tobbbie,
I have a Globalsat BT 338, I would like to update the firmware. I downloaded your dumps from http://www.gpspassion.com/forumsen/t...5&whichpage=11, the 3.1.1 version.
Do I understand well that even exists a 3.2.2 version?
If yes where could I find it?
Thanks
patek
It's in the same forum a few post further down - it comes from another member there - just look it up.
Edit: just checked - it seems only the 3.2.4 of the BT368 is there.
I have edited my old post there with a new link that has all info - also for short here:
http://rapidshare.de/files/41287744/Firmware_Globalsat.zip.html
Please read the GPS passion forum entries very thoroughly - it MUST be complete dump that you insert - anything less than 512kB will kill your device (as a poor forum member there had to suuffer)..
Tobbbie,
Thank you for your prompt answer,
I checked my software version, Sirfdemo says: GSW3.1.1LowV_3.1.00.07-c23B1.00 - the same what yours was before upgraded.
I read your opinion about changing to 3.2.2 :
>As mentioned earlier I have yet to discover advantages of 3.2.2 or 3.2.4 over 3.1.1. I >think some trickle power options are more flexible and the DGPS could work - but so far I >could never get a DGPS fix.
So do you think is it worth enough to upgrade? (green lamp!)
Is the WAAS enabled in the 3.2.2 ? (maybe silly question)
Thanks

Hi,
I am having a problem and, to be honest I know there is going to be someone out there that is going to moan about this thread, frankly I don’t care, I have done so much reading into this question I am getting really f*****g annoyed/frustrated with my seeming inability to find a straight answer.
Is there someone out there that fancies donating a little time to help me learn, I say learn because that is what I want to do not read through pages and pages of
STRG handles: 834d5e62
0 partitions, 0 binary partitions
customerid=00000000 uniqueid= 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

0 partitions, 0 binary partitions None of the above means anything to me, it is an extract from something in the wiki about dumping ROMs. I have found various tools to do the things I want but when following instructions given I never get a result.
Basically what I want to do is, dump a ROM, remove software I don’t want, add in my own software (some OEM, some CAB – think I need to know more about the ExtROM?!?), recompile and flash.
While I think that the guides provided are accurate and all credit should be given to the writers, for a beginner they are too complex, there should be one idiots guide!! is there someone who could tell me, indicating what software needs used and how to use it, the steps needed to do this.
Thanks in advance for help!
totally agree!!!
Hi bennec83,

It is nice to know someone agrees with me, ive read pages of stuff, even read a 14 page instruction book for "Molski.Biz DEVPACK" while this seems to be the most straight forward yet, i still cant find where/how to add/remove applications etcto the decompressed rom!! ive been trying since 10:30am its now 17:00 and still nothing!!
in answer toyour question about downgrading to WM5 see this link and follow the guide:

Any Help would be appreciated!! i am getting to the point where i am willing to pay someone to help me!!
well the easy way is to use whats called the "Core Pro" ROM kitchen... its released on this forum and has great instructions on how to use it even for new cooks. Take a look I think you will learn a lot from it.

Sorry for late reply, i was awake so long trying to get something to work, i nearly over slept my fight!! lol

Shadow
20070616_LSVW_Hermes_WWE_3.30.3.3
Sleuth255_CE5.2.1413_Build_17913.0.3.0_v1.0
Schaps_WM6Pro_WWE_3.30c
(mainly been trying with 20070616_LSVW_Hermes_WWE_3.30.3.3 & Sleuth255_CE5.2.1413_Build_17913.0.3.0_v1.0)
2)Tools Tryed (on Vista and XP) and results:
Platform - Software - Result
Vista: - Molski Biz DevPack - seems to work cannot test as NBHExtract(DL from XDA-Developers) crashes out
Vista: - Olipro's Kitchen - All exe files crash out, cannot use
Vista: - Tadzios Kitchen - All exe files crash out, cannot use
Vista: - CorePRO Kitchen - Only one that works on vista but im not sure wat its doing, i can dump an nbh, moved OS.NB to ROM folder, can perform automatic convert of DUMP into SYS and OEM, then from here im fuzzy on what to do.
As far as XP goes, only thing i have tryed was running NBHExtract last night and it crashed out (VB error, not sure if right version is on system - Thanks [email protected]!!), i will be doing more on XP when i get back this afternoon (approx 2-3 hours).
i have read the instructions from all of these kitchens, they are all roughly the same, i got so far with CorePRO kitchen, by using the tools from it in conjunction with the instructions from Molski Biz DevPack as they seem to be the most logical!!
There should be a kitchen made for people like myself, who are clueless but fast learners, if i can get a First Class degree in Mathematics, i should be able to do this, if i am shown the light.
This N00b kitchen, in my opinion should be labeled in number fashon (i.e. 01ump, 02:convert dump2sys+OEM, 03:add/remove software, 04:themes/splash screens/today screen (although the today plugins prob would go in with 03)), 05:start menu customisation, 06:rebuild (It Could Be That Easy)
OEM folder should be sorted (if possable) into software files each file containing the files for the software, not dumped in a folder called OEM, if i want to remove a piece of software from the OEM folder i cant as i dont know how many/what files i should delete specific to the software i want to remove.
I have been trying to complete just one ROM for myself and i have been trying for weeks, i have privately contacted moderators and chiefs at different points and asked for help, i have read the wiki, i have learnt so much other stuff which is great, there has been numberous occations when i have felt able to help other people out which is what i like, i think with this ROM cooking i have readingto and not understood so much i am starting to go in circles without knowing.
thanks all for responses, XP testing will resume when i finish my thai match.
Spk soon thanks again, and i hope we can sort this.
Ill guide you, contact me on MSN or IRC or skype
can anybody tell me, my original bootscreen was telstra,
when i upgraded to black 3.5 it changed it to 4winmobile.

Many thanks!
i have one. they sent it to me coz i complained about noise being picked up by phone1. tried reflashing, but still the same problem.
Hi I have a HKC G1000, and do not do as a HARD RESET, as you know, thanks

how's the sound quality of your phone?
i have a problem with phone 1, it picks up alot of ambience noise.
difficult to hear the other person you're talking to.
if you put your hand over the mouthpiece, and also the earpiece, it creates a feedback sound.
no problem on phone 2.

Hi Pranix,
thanks for the rom file after i'll ask you how to flash it.
My phone works good both sims, your, sounds to be an hardware
problem, since you told that you have flashed the rom.
The set of the microphone for the sim 1 is too sensible, and when you put the hand on the micro, it cause what is called "larsen effectc", that happend when the sensibility of the microphone is too high and trigger a feedback from the earphone that cause an annoying whistle .
In an italian forum, I heard about an engineering code to write down in the
china phones with WM6, that allow you to set some hardware features
of the phone including the sound level, I don't know if this is possible also with our phone. but it worth a try.
I'll go to ask in the forum and if pertinent, i'll post you the answer.
Bye
hi,
the procedure to flash is in the rar file that i have uploaded.
just open the text file.
hope you can find some way to minimize the sensitivity of microphone setting for phone 1.
regards,
pranix
Hi Pranix,
he say that the code "engineer mode" it is available only on the china phones with the RTOS operating system, and in some motorola and Nokias,
but he say that maybe it is possible to change the parameters set on the windows registry, with a pc program like CeRegEditor.
Connect the phone to the pc, start CeRegEditor, make it read the registry, click on unlock (if not you can't save the changes), after that you have to look where are located the keys regarding the audio, and see if modifiyng the key value you can solve the problem.
I will look further if i find some else solution
good luck
i already tried editing registry however still the same.
maybe i was editing the wrong registry. hehe
i just hope that 9rinder gets to post his rom here

i've actually tried editing those registries before however still the same.
the question here is that do we have one or two mircrophones?
coz if only one, then there must be a setting somewhere to adjust phone 1 & phone 2. phone 2 sound is better than phone 1.
if two microphones, i cant find the settings as there is only one setting to tweak.
Hello. I have one of this PDa.
Mine has this ROM:

Do you recommend me to update?
Is any way to "extract" its original ROM?
And is any way to "edit" any of your roms to change the language of the OS?
Thanks
This is the solution for unlocking Wave phones.Big thanks goes to mijoma.
All you do and enter into your phone you do at your own risk. Nobody else but you take whole responsibility for what happens to your phone!
Remember than flashing of phone is a little risky, however if performed properly, risk of damaging anything is very low.
If your phone locked-up all of the sudden - be sure to read this thread aswell: http://forum.xda-developers.com/showthread.php?t=1787648
Most of bada 1.2 and 2.0 final-release (not ones from beta releases) bootloaders should be supported.
You need some knowledge about flashing.
How to check what lock do you have?
Enter *#7465625# code, you will see list of active and inactive locks.
What do you need?
Wave 1 or 2 phone with bada 1.2 or 2.0
For Wave I with bada 1.2 - FLOCK_S8500_b1.2
For Wave I with bada 2.0 - FLOCK_S8500_b2x
For Wave II with bada 1.2 - FLOCK_S8530_b1.2
For Wave II with bada 2.0 - FLOCK_S8530_b2x
Flash the right FOTA file. Turn off the phone, wait few seconds, and then turn it on holding CALL (so you have to press CALL and ENDCALL, 2 keys) key until white screen with red texts shows up. Release keys.
Be patient, FOTA module is calculating 3 codes (Subset lock, Netlock, Unfreeze) for your phone, it can take up to 10 minutes. After you get the code you are interested in you can turn off the phone.
Write down the codes you need. Turn off the phone by holding power button for 15 seconds or taking off battery.
After obtaining code, do procedure below:
[Netlock], 2 ways:
1. Insert an unsupported SIM card, start phone and after being asked about "Network Lock" enter Unlock Code you had written down.
2. enter #7465625*638*Unlock code# <thanks to homelessghost for tip>
[Freeze]
1. Insert any SIM card, start phone and after being asked about "Freeze" make call and enter code you had written down.
[Subset]
Can anyone provide guide?
That's all - enjoy unlocked phone!
Troubleshooting:
Instead of white screen with red texts, usual booting logo appears and then Bada starts, what am I doing wrong?
Make sure you flashed right FLOCK without errors. If you did so, first - flash APPS from the same bada version, but from ROM that does contain .fota (certain APPS versions can have locked FOTA module), second - if it doesn't work - update your bootloader to some newer/another one and write post here containing information what version of bootloader (bootloader, not bada) you had before that was not working.
Important: Be very careful when writing down and entering unlock code.
If you got any other questions - please ask in this thread.
It is possible that some phones are not unlockable this method. Then the code wouldn't show up.
General method concept (if you are really interested in sources or way how it works - please PM me or mijoma) should work for most of "Samsung 3G" phones - like JET, Wave3, Monte. If you are owner of locked phone of this class and you are able to do dumps of memory - please contact with me.
Hi,
Thanks a lot for your job, you're my god
Here's my Hash: C7 2D C4 73 07 18 FA 2B 15 7E 29 07 3F BD 04 2E C7 4C 82 E6
Thanks
Thanks so much Rebellos! My phone has been network-locked since I got it and always unable to update with Kies, so I've been stuck on a May 2010 Bada 1.0 firmware forever. Looking forward to being able to flash it
Speaking of which, I've always read that you can't flash anything to a locked phone. Is flashing the bootloader and FOTA alright though? And will the bootloader be compatible with my firmware? It's S8500NEJE6/S8500H3GJ7.
If that is fine, then I'll send you my hash. Thanks so much for doing this!
Thanks a lot, Rebellos!
Here it is my hash code (I only have the network lock):
01 6C 99 C4 BF DC 57 72 B1 23 2E 0B 4C 71 C8 0E C7 DC 79 47
Thanks again!
Very interesting your project but there is a problem.
In Latin America can not change firmware and than through KIES .. we can not use the "Multiloader" because we have the code "SUBSET [ON]" and if we have the code that the [ON] and flash our phone freeze only makes our telephone and so we are unable to use your tutorial.
You know any way to change the code first "SUBSET" to [ON] [OFF] and by doing so Latin American users can use "Multiloader" how many times we want.
I hope your answer and relied heavily on his wisdom!
Already many thanks! Greetings from Argentina!
Phone can be flash-locked - then bootloader will deny any attempt of flashing, though I can't promise I haven't ommited some malicious procedure allowing something like bootloader upgrade but refusing firmware upgrade and refusing bootloader downgrade, causing kinda brick.
Is it a rule that phone flashing is locked always when its [ON] SUBSET Lock?
I will try to look into it.

Does that mean it's safe for me to flash bootloader and FOTA if my phone is only network-locked?

OK, thanks. Presumably there is no way to obtain the hash without flashing? I suppose it should be fine since those who have already given you hashes must have flashed their network locked phones with no problems.
In "theory" there AT Commands and/or Dev Commands... in combination with WinComm to see result.
Theory because not my business and I have no locked device for tests.
Anyway.
It is ever interesting, how many ways exists to disable Security.
@ Rebellos
Maybe you can teach me how to copy/find "SIMSecure" area in JTAG dump.
Then I could check if my theory is bull.shi.t.
Thanx.
My hints NOT for public... only for my little brain.
Best Regards
Ok, thanks anyway
If we who possess a Wave in Latin America we have all the [ON]. The only problem is the SUBSET flash. If we have the SUBSET in [ON] the phone freezes (unnfreeze mode) after using Multiloader.
It would be good to try to change the way SUBSET to pass it to [OFF] and so test any firmware.
Thank you very much for your response. I hope you find some solution for us because we feel like slaves and prisoners of samsung and has forgotten us regarding updates and all you have to do with the Wave.
Thank you very much! Greetings from Argentina!

The hash is generated from IMEI somehow. But I don't know how yet. I flashed my networklocked wave like hundreds of times with no problems. Even updated it from 1.2 to 2.0 while it was still netlocked.
@adfree:
These data are encrypted with SEED algorithm using key generated from oneNAND serial number. Are you able to obtain it?
@elkpojlb
It needs some work but can be done. Though I'm out of time for next few weeks.
Well no problem friend .. long time and we hope some solution so that we do not do anything but wait a bit! Thank you very much and I hope they can do!
Greetings friend!

Wow, that's news to me, I've never flashed because I heard it'd brick a locked phone. Now the noob question, which checkboxes should I tick in Multiloader for just flashing bootfiles and FOTA? Boot Change, Full Download or nothing at all? Or does it require one flash for bootfiles and another flash for FOTA? Sorry - the next post from me should contain a hash!

Boot Change, then select directory with bootfiles and file with FOTA. Try to find some tutorial before you do it.

Hi all
I want to present you the work done by Serg090909 on the 2 Din Chinese Car audio system many people begin to use.
This sort of Car audio use WinCe 6.0 for Radio/TV/BT and the Android part for GPS and everything android can handle.
I only found information about modification in russian language by this famous guy i want to thanks gratefuly : Serg090909.
He made possible to boot from Sd-Card new builds (apollo tvbox and caravn776 build) for this sort of car audio and called it "GIBROID".
With this way, you don't touch at the Nands and don't damage your system.
Insert back your original Sd-Card to boot normally, nothing is replaced in the nands when you switch to your GIBROID Sd-Card
Work has been done to backup your nand and write nand again, but for end users GIBROID from Sd-Card is a better thing and the easiest way to do.

I 'll post pictures and updates to this thread and if anybody is interested in helping me reporting in English the continuous work of Serg090909 you are welcome to participate and report results here.
Thank you and have happy tests.
To readers : Respect the rules of XDA Forums and don't link to warez sites where you could found information about this
To moderators : Could it be possible to give me the right to post hyperlink or if not possible i'll wait 10 posts
To Serg090909 : I don't speak russian and Google translations are not easy so if you want to help here you'll be my guest star
HOW TO :
Install GIBROID on Sd-Card :
- Use Win32 Disk Imager (sourceforge.net/projects/win32diskimager) to Format Sd-Card and write "GIBROID-4G-11012014.img".
This image is 4g space. You can use max 32g Sd-Card, but since this operation use all the space of the Sd card you are invited to expand the rest of the Sd-card space for User space
- Use MiniTool® Partition Wizard Home Edition 8.1.1 (partitionwizard.com/free-partition-manager.html) to expand the Sd-Card space.
- Place your GIBROID Sd-card inside the GPS Slot and keep safely your original Sd-Card.
Screenshots to Switch from Apollo to Caravn :
See (Screenshots) Switch from Apollo to Caravn.rar Attachments
Backup/Write Nand for "experts" :
Dump to the Sd-Card
- Download the script a10-Backup-SH (See Attachments). Copy it in the root of the SD card
- Install SU and Android Terminal Emulator with Play Store
- Run the terminal and see the operating system prompt a dollar sign ($)
- Type su and press Enter
- Type cd/mnt/extsd
- Type sh a10-backup.sh all
Restore Dump
See "Restore Dump" attachments
Compatibility List :
Klyde KD-7200d
Erisin
N708
Post your models
...
...
Hints :
Not related to GIBROID, this sort of car audio have a Hidden Menu in WinCE6 Part.
Hidden Menu :
- Go to settings
- Press 1357 with the remote controller
- Tadaaa !
Credits and Thanks all goes to Serg090909 and all the peoples involved in explanations, informations and helps.

I installed this image onto a SD-card and it worked! It is verry stable and I didn't have any hang ups on boot! GREAT!
I have a couple of questions/remarks
The boot image is a skull and I want to change it to something more friendly Where can I find this image to change it, using total commander to do it for example?
Thing is: Now my bluetooth dongle doesnt work anymore. I have the buetooth button but I cannot turn it on (well, I can but it turns off again)
Even if I try to connect my dongle directly without HUB it doesnt respond. Is this a driver issue or do I have a wrong dongle for this image? The old serge Image did work with my dongle so can someone tell me if they have BT working and which dongle they use?
Also, the Wifi dongle doesn't work as well as it used to. I didn't have much time to figure out what happens but it connects but drops connection and doesnt work that great,. I will keep you guys informed if I know what the wifi dongle does and doesn't do.

Serg090909 is working on a new build that will be released shortly based on Apollo. The Bluetooth will work again.
Teaser
The actual build you use don't contain Bluetooth libraries, that's why you can't use Bluetooth (can be implemented manually with terminal but didn't test since a new release is coming).
Of course you can change the wallpaper as you wich like you would do with your phone and the boot image too (but i didn't digg to find the boot image actually).
I don't know what to say about your wifi, my dongle works like a charm without connection drop.. Maybe the wifi implementation was a bit buggy for some.. Let's wait for the new release !

Thanks Chandler13!
You and Serge090909 have been a real help on this topic. First I thought no one would care about these android radios and I would be stuck with the stock firmware! Now, I have a radio which does so much more and it looks nice! Even if there is going to be a new release which I cannot wait to put into my radio!. The teaser looks nice and has a great look/skin. I didnt understand what this apollo was, is this the musicplayer? It looks great anyway! I was just wondering, since we are running the OS from a SD-card, is it possible to make the internal memory a little bit bigger. This way we could install apps with no bother that it runs out of memory. 2 GB would be more then enough. I am running the OS from a 32GB-Sdcard so I have room to spare :laugh:
Thanks for the tip for the background, I allready changed the background but I didn't find the boot-image either...
I allready solved the problem with the wifi-dongle. I was in my car and next to my home, but my wifi signal wasn't that great. I used my iphone to make a hotspot and it worked like no other!

Apolllo Tv is another build in short, Serg090909 gived us the choice to launch the "Caravn" build, or the Apollo Build at first start till you choose to boot only one of both. Clean launcher parameters to take a look at apollo UI.
I just reported the very good work done by Serg090909 and i'm glad i'm not the only "french-english and others" to enjoy his work.
Believe me, it's a pain in the ass to traduce russian to english for a french ..
Of course you can expend the partition, i'll post more about this and making own builds.
And about a surprise i'm preparing for the WinCe part....... :angel:

I also had the honor to translate some posts from Serge into english and I must say Google translate does a hell of a job. I didn't expect that :good:
Sure, you do get a lot of jibirish but if you read carefully you can allways make out what it says.
I'm actually dutch so my french isn't that good either. So i'm glad this wasn't in french or else I would be translating my ass off
Keep me updated about your surprise and the new build. I can't wait!
Any news on this new ROM?

Man, I'm very grateful for your big help! I have a N708 installed in my new civic 11 and the worst problem is that all I install in android comes to the internal memory not to the SD card, can I change this?
Move to NAND??
Hi I´m from Argentina, and I also must thank Serg090909, Chandler13 and Google translator. They made up a team that brought my unit back to life!
I had a problem with my original rom and screwed it up trying to fix it with terminal commands. It didn't boot at all and I couldn´t find a solution until this thread.
Now, I wanted to know if there is any way to flash this rom to the internal nand. I got nothing to lose since the damage is already done.
Thanks in advance!
Hi all !
Hello,
I'm french and I'm interested by this thread forum...sorry for my English.
The mine update via sd card too.
I have this model of car audio (WinCE 6 + Android 4)
Can confirm that it would work with my car radio?
Otherwise, I do not understand ... What can it do for me? boot other bluids with bluetooth support ? no affect my actual firmware ?
PS : I try this : in CE mode : Go to settings, Press 1357 with the remote controller..... but nothing appear
--> This might help people who have the same as me!
------------------------------------------------------------------------
Otherwise, I had a startup problem on android, I asked the firmware to the dealer:
I managed to restart ... but it does not have me delete all my installed apps, just allowed me to restart (I do not know how, but its work (the firmware is 210 MB).
This firmware link (with explanation) :
https://www.wetransfer.com/download...71d307e45402858f585c713020140228070442/b7d4f9
thx!
Reflashing
I think that this thread is dead. I hope I`m wrong, since is the only one that deals with firmware for the device I have.
I tried to connect my laptop to the head unit and flash the firmware to nand but i failed.
What I did:
1) power off unit
2) connect laptop to USB OTG where the wifi dongle is, using a male-male usb cable.
3) power on unit holding menu and volume knob pressed.
4) screen goes black and stays there.
5) computer detects nothing.
Possible causes:
My android system is beyond repair ( I don't think this could be the problem, since it boots perfectly with gibroid on SD card)
too many extensions for usb cable. 1from the back of the unit to the dashboard and then the "male-male" usb cable...
Many many other of which I have absolutely no Idea.
In addition to this, livesuit tells me that gibroid image is not valid.
Any ideas?

Hi,
This is not OTG, in order to connect to android part via USB you'll have to disassemble the unit and find a real usb otg on android board. it is located right next to the socket where the 'wifi' marked cable is connected.

I've been reading about phoenix card software. Apparently it could flash the firmware from an SD card for allwiner chips. I guess I could try that before disassembling the unit. I'll let you all know how that goes.
Just seen that there is a new firmware out for our Xperia's. Can we have some feedback from people who have downloaded it.
Date of security patch?
Fixes restarts?
Power consuption?
Anything to report.
Got it OTA 5 minutes ago. Can only report December 1st security patch so far.
Wow they must be having serious issues with recent releases, what with the abnormally frequent revisions and pulling some offline.
Glad they included the December patch in the latest release.
Still sucks to be stuck on .374 though, with no camera distortion fix
@mhaha
Could you check if the app drawer opens if you swipe up in home screen (and you can go back to homescreen by swiping down in app drawer)? This seems to be new in this build. (I can not check if it works in an older one.)

This was a new feature implemented on a recent update to the home launcher app (11.0.A.0.8), and since I updated it, I have this function in .374.
It's not tied to the firmware version.
EDIT: I updated the app through Google Play, they have a list of changes posted for the new launcher. Wish they'd do the same for firmware updates...
Hm, strange.. Mine xperia home version 10.2.A.3.25 says it's up to date. Also the changelog only says "bugfixes". (inside "more" only generic stuff like "full integrated google-feed etc.)
Hm, okay.. inside the home settings it says 11.0.A.0.5
Installed on my phone last night. It seems very smooth, I can't find any problems.
Bluetooth problems I had with connecting to things seems to have resolved. Previously the phone wouldn't automaically connect to a device, even though it was the only thing in range.
The camera fix is the most obvious thing, this will be new for people who didn't get the 47.1.A.5.51
Monitoring battery life now to see how it compares.
Phone just rebooted, so the new firmware didn't fix that.
I still have Bluetooth issues, i.e it wont automatically start playing music but FF/REW seems a bit better, but i still get no track names on my cars inbuilt head unit.
Seems a Little bit smoother imo. Still apps still freezes from time to time. Seems like battery is back to normal again. If u experience batterydrain anomaly, try updating play service to .51 Beta from apkmirror.
So far .49 seems good, the battery seems to be much improved ?
All,
I would note that it appears (per screenshot here) that you can't downgrade to a previous version once you've installed the 47.1.A.8.49 firmware.
I suspect they have enabled Qualcomm's bootloader versioning which prevents the system from booting when it detects the older version.
This probably means that there is a serious and potentially easy to exploit vulnerability in the previous versions of the bootloader. Note the many closed source Qualcomm vulnerabilities listed in the December ASB.
It's possible that someone will eventually discover what those vulnerabilities are and come up with a way to root without unlocking the bootloader.
Personally, I'm staying away from this update for a while.
EDIT: I was wrong. See below.

The update screen has always had that disclaimer though, for each and every update I've ever received - and I've owned nearly every Xperia compact.
If you only go the official route, downgrading was never an option.
If they implemented a way of preventing one from flashing an older firmware even when using third party tools like Flashtool or newflasher, then that indeed is news, and bad news at that. But the screenshot is largely irrelevant.
unfortunately I don't receive any updates for mine it's still on "47.1.A.2.374"
When I'm conected to WLAN and search for new updates via "Settings --> System --> Softwareupdate" it tells me that I already have the newest updates installed

You're correct and I was wrong.
A user was trying to downgrade and was getting boot-loops and another user pointed out the statement in the ROM.
I knew that there were a lot of closed source Qualcomm updates and assumed that Sony implemented version rollback prevention.
They did not.
I was wrong.
I pulled the attestation certificates from all of the firmware versions released thus far and compared them.
They are identical.
Code:
CN = Yoshino com-2 Attestation Cert
OU = 01 0000000000000001 SW_ID
OU = 02 0005E0E100010004 HW_ID
OU = 03 0000000000000000 DEBUG
OU = 04 0001 OEM_ID
OU = 05 00020000 SW_SIZE
OU = 06 0004 MODEL_ID
OU = 07 0001 SHA256
O = Sony Mobile Communications Inc.
L = Lund
S = N/A
C = SE
Note that the "SW_ID" is the bit used to implement rollback prevention and is actually supposed to be read in two parts:
0000000000000001
The red bit is the version number and the green bit is the image identifier.
Essentially, the version number hasn't changed, so we can still roll-back to a previous version.
The user with the problem likely has some other problem unrelated to bootloader versioning.
I apologize for the misinformation.

Do you know how i might go about troubleshooting the problem? I'm grateful for newflasher and can follow directions pretty well, but obviously something went slightly wrong. Is it my own fault for not flashing over my user data? it worked fine when i flashed from .51 to .7.1.

I still have Bluetooth issues, i.e it wont automatically start playing music but FF/REW seems a bit better, but i still get no track names on my cars inbuilt head unit.

I had the issue with not getting the track names as well. Solved by changing AVRCP to version 1.4 in developer options and then re-pairing (forget the device and then pair again) with my Kenwood head unit. Media controls also work fine.

I have a Pioneer and I don't have any problems, regardless avrcp version

Thanks so much for this. This workaround fixed the title display in my Hyundai .
Does anyone of you also get worse battery run times? Mine phone is (only 30min sot) in standby for 1d14h and already at 45%... Standby showing 17% consume, Android OS12%, mobile standy 8% and (RCS) phone 7% which all together seems pretty much... Before this update I got runtimes for 4days+, not I already have to charge after 3 days.
(I did not uninstall or install any new apps.)
