A vs V logic board - Galaxy Tab 4 Q&A, Help & Troubleshooting

Good evening all,
I don't know if anyone has done this before. Is it possible to use a "v" version of the same logic for a "a" version? :fingers-crossed:
Its primarily used on WiFi.

Different build version of O/s on MDA to JasJar

As the title to this post states, the build versions for these two devices are different. Surely a ROM upgrade will not alter the version of the O/S will it?
MDA Pro: Version 5.0 OS 5.1.1700 (Build 14352.0.1.0)
Jasjar:Version 5.0 OS 5.1.1700 (Build 14354.0.1.1)
Could this be the reason for differences in performances as well as potentially different chipsets in these devices?
Some Universals seem to overclock comfortably whilst most don't, fact!
Some Universals display certain other problems (who cares which ones right now), which others don't, fact.
Readocket Hack tops out @ 520Mhz on jasjar but 624Mhz on MDAPro
It's beginning to look like it's very plausible that HTC may have used different components (with the same spec) to build the Universals and it is a fact that we're not all running the version of operating systems.
It's therefore little wonder that we are all getting such conflicting experiences of good and bad scenarios. Correct me if I've misunderstood the facts and am assuming too much here. But if we are not running identical hardware, let alone operating systems, how can there ever be a universal ROM to cure the varying types of Unversal machines?
Can anybody please shed some light on this as my understanding of these issues is limited. :wink:
No Problems on my JasJar
to expand slightly for those who haven't already read this elsewhere...
Without taking screws out and checking chip numbers, my device and mackaby007's are identical in every way (ROM, Radio, Protocol, Build Number) The only possible difference is that I didn't load any of the extended ROM. (not sure if mackaby007 did?)
However, I have no problems and mackaby007 has...one or two:!:
As he says, is there ANY explanation for this? I understand we're both using minimal amounts of software. All I have loaded at the moment is the latest versions/betas of:
Resco Explorer and Radio, TCPMP, Pocket Weather, Pocket Breeze, and at the moment PocketHackMaster. All thoughts appreciated...
Edit: (I forgot I've got a Citrix client installed too...)

Yep done that last night (minimum ROM applications install on hard reset followed by soft-reset befor the useless stuff starts to install). Then I ran the Jasjar with just TCPMP and then with HackMaster2005 installed (only). Yet it still bums out. Any suggestions anyone?
I also concur with mackaby007 and sub69 as my JasJar is now identical to sub69s (Rom revision and no external rom loaded - pushed reset button) however I am still unable to overclock the device to 624mhz in a stable fashion.
My JasJar will clock to 624mhz and will not crash however at that speed the LCD gets the occasional flash vertical line somewhere on the screen.
I put it down to the fact that this machine was designed to run at 520 no more so other components in the board layout use a lesser tollerance than if they were aiming for 624. This could be as simple as resistors capacitors transistors. If youre lucky your lesser tollerance part will be within tollerance of a better part and so will overclock better. Its kinda like blueprinting an engine. you use all standard parts but to the tightest tollerances possible and you can get great power gains, same engine same parts but picked at random produces a production engine with guaranteeable results.

Wlan for Pharos (Some common features of all OMAP 850 phones)

I thought it was so strange that when I scanned for bluetooth devices I picked up my (pc) internet modem (which is wireless enabled) so I thought bluetooth and wifi must share a lot of the same characteristics.
I was browsing for the latest Android developments and stumbled on the following
Please take a look at this page http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12000&contentId=4679
And this one http://focus.ti.com/general/docs/wtbu/wtbugencontent.tsp?templateId=6123&navigationId=12019&contentId=4635&DCMP=WTBU&HQS=Other+OT+bluetooth
This seems to mean that FM Radio and WiFi is a standard feature of OMAP 850 chips and (for the touch owners look at this page http://focus.ti.com/general/docs/wtbu/wtbugencontent.tsp?templateId=6123&navigationId=12028&contentId=4636&DCMP=WTBU&HQS=Other+OT+agps)
Seems If you have Bluetooth you also have wifi and possibly fm radio built in only lacking the drivers (no special wifi antenna is used in the omap 850 solution accoriding to TI)
It would seem that all we need is the right drivers and regsettings (so no new rom or radio rom should be needed)
Who can make it a working cab?
Woooooooooo!
Good news.
great job
if some solution, make me to buy one.
by the soft solution, strange story !no idea for none cost effective option. why do HTC designers make a 2008 PDA with no WiFi Option!
wow
wow...it might be dream come ture if it happens....please some body develop a driver for pharos Fm radio n wifi.....please buit up some regsettings......
This is a good information. Hope that we could make it work on our Pharos.
Good News... I hope who will make it soon because I don't understand about ARM work.
That is an awesome find man. I hope this info is used to get a wifi working ROM.
I thought it was some kind of cost saving to not include wifi, i.e. some missing hardware. If it's just a driver, that is the so friggen stupid! Why have such a great phone and then neuter it by taking away wifi? And the price is still just as high as the Artemis when it came out. The lack of wifi is the only thing that would keep me from buying one. Otherwise, it would be a great upgrade phone for me since I don't need nor have 3G with my service and and it has the cool flush screen that I wish my Artemis had.
someone knows if the touch dual then also could have the wifi option turned on by drivers? the touch normal has wifi, so i guess it should be possible.
anyone tried the drivers from the htc wizard? it also has a ti omap 850, so driver from such a rom could be coocked into the rom of other devices.
@VOODOOS!L
The touch dual uses the Qualcomm 7200 chipset. That chipset uses the arm926tesj as a co processor but i dont think its the full OMAP 850 chiset.
but there is a project for enabling niki wifi (started out as a project ot enabkle both wifi and gps)
@shawndh
Phone manufacterors do it all the time. Look at the Kaiser story, yes they have some great graphical chip (would be too expensive to make a different chiset with another graphical chip) so they just didnt include the drivers for it.
With some other phones like the touch HTC disabled the wifi in the radio rom... maybe some techies here could try to put an artemis radio rom in the pharos... but for none techies this would probably be an instant brick (thats why i didnt try it) tom_codon maybe you could say something about this....input would be apreciated.
Come to think of it, I remember that they had a crippled GPS radio or something in the TyTn I. The only reason I could think of for disabling wifi is so people who need wifi would buy the the Artemis. To be honest, if I had a choice btwn the two, I would get the Pharos over the Artemis if they both had wifi. Even so, it should still have wifi.
This ia a good news.
I'm waiting.
you know what... im giving up.
ive tried pm ing some guys working on the wifi on nike project, asking tomcodon. no response as yet and prolly not going to get one.
And tried to get qtopia and winlizard(gizard) working.
but in the linux world up is down, left is right, and smart is stupid. those people are (in dutch: contactgestoord) communicationally challenged. you cant find anything on their sites. there is no(or very little) documentation on how stuff works ...noone explains anything... so in order to learn linux you have to know it.
thats why m$ can afford to be so sucky: their competition sucks so much more
i said to the guys at irc #linzwizard hey thnx for the build, i can boot it too (gizard aka linwizard 0.3.0) but the touchscreen driver crashes.
he then said make a support request at sourceforge which i did (btw it isnt obvious how to .. it should be very simple. but hey... thats the linux way, isnt it) response was.. and this is a shocker.. your touchscreen driver doesnt work(.... grrreeeaat) you should disable it...(no description on how)
up for the rom with wifi for the pharos!
Thanks
Not to rain on anyone parade but from the first page from TI, it looks like to get wifi support you have to have a special chip in the phone(upper left corner) thats diferent that the chip to get wifi, so unless someone knows for sure that the WiLink chips are present, I think we are without wifi
Wait and see...
The only problem is... How long does it take to finalize such a ROM?
If it takes 1 yr, for example, I think I will have already changed to at least TouchHD..
Anyway, good news!
Hello! I have a HTC Pharos for one month. Yesterday, i accidentally have wetted phone by tea, and then i disassembled it for cleaning. Cleaning was finish sucсessfully, now phone is working
During disassembly of the device I have made some pictures. I think Wlan module is in the device. Look at the photo! Motherboard have many connectors for external antennas, and Wlan connector is on the board!
http://www.flash-remont.narod.ru/pharos/pharos.jpg
thank you for the picture, its in a good resolution! but what would have made it more clear is if you would have looked for a specific Texas instruments chip with letter combinaton BRF or BL (there are 4 chips mentioned with a dual solution BL6450 BRF 6350 BRF6300 and BRF6150 last one is not good because its a bluetooth only chip) we should also be looking for TI chips with a WL designation and number 1271 1273 1251 1253
at least (BRF6300) - Bluetooth specification v2.0 + EDR single chip should be in the Pharos since we have that bluetooth spec.
in the picture i can make out the TWL3027 chip with extra designation BZQW (at least i think its that chip ... according to the ti site that would be the baseband chip but it doesnt describe on the site what the extra letters mean)http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12311&contentId=4706

hope this is readable since i have a hangover
Kostyan could you post the other pics you made of the interior of the Pharos

Maybe this iron box is Wlan module?
http://flash-remont.narod.ru/pharos/pharos2.jpg
I may open this box, if it is requires for this research
And on this picture, front side of device it is found Wlan antenna? (if overwind board, supposed Wlan module with connector correspond (matched) to on position with Wlan antenna, and it connected with module)

[Q] Changing ROM of a China Phone

Hey,
I've got an MF68 / IP800 (It got so many names that I prefer to call it "Horza", sounds pro - There will be a picture of it on the bottom of this post) and it came with a Windows Mobile 6.5 Professional - CE 5.2.23090 (Comp. 23090.5.3.0) - Yup, it ain't a rip-off windows. It's a rather good phone, with a slow-but-does-whatever-I-throw-at-it processor "HUAWEI HiSilicon K3", running at 360MHz (I've seen versions running at 460, if anyone knows how to overclock it, it would be welcome), 128MB RAM and 256MB ROM; all those controlled by a 240x400 3" resistive screen. Not a lamborghini but does the job well done.
Anyhoo, I want to change the ROM. Somehow it limits my volume to 63%. It might be good for my ears, but it's a real pain when I connect it to an external speaker. Also, there's a few ROM's possessing some sleek features that I'd love to use. But there's three problems:
1 - It's a dual-SIM phone (the actual ROM seems to be adapted, or something, for this - due to the poor, china-style, translation in the Dual-SIM Setup area)
2 - It's a china phone, thus I don't know what I'm supposed to do or if it's able to
3 - I only have the original USB Cable. Will it work or I need some sort of special cable?
So, what should I do? Will it be able to update? Which programs should I get?
Thanks for the attention and I'm awaiting for an answer
Sincerely,
GTMoraes
well if you say that its a legit windows mobile device then you should be able to have themes for it however, some things like hardware issues are going to get in your way.
1. Dual-SIM
2. Screen Resolution (not anytheme will work)
3. Thats all i can think of...
4. Will think of other stuff and come back to you
Yup, I can use some themes for my WM, I've got tired of the Titanium style and ATM I'm using the SPB Shell, works like a charm.
The actual O.S. works fine, but it's limiting the volume to 63% (according to 40iPlay and proved through external speakers). I've googled around and it looks like an European or something limitation, removeable only with a new ROM - so here am I.
Is there any program that I should run to see if my phone is compatible with ROM updating?
Thanks for you answer and I'm awaiting for new ones
P.S.: Anything related to the Samsung i900 works flawlessly on the Horza. So does the HTC gSensor
I have a China LEO 8585 and have yet to find a custom rom myself.. sorry bud.

Upgrade GSM and GPS moduls?

Hello guys, I hope I'm right here and you can understand me.
I wanna buy an Android box like the Scishion V88 for my car-pc project. For Google Maps and other Apps, I need GSM and GPS and I know no box, which provides both.
So my question: Is it possible to upgrade GSM and GPS USB sticks on Android 5.1? On my research, I found some topics but these topics are very old.
I think it's not plug & play but no problem, because I wanna use an custom rom for the box.
Have anyone information for me?

Bluetooth differences?

Hello,
I want to help a friend with continuous glucose monitoring. His pomp hardware has bluetooth and it is possible to connect it to phone. But only a few phones are compatible - Iphones and a few models of Samsung. When you don't have a compatible phone application displays error.
So, I edited build.prop and application works but I can't find CGM device. I wonder why. What is a difference in bluetooth module in samsung and one plus 5? Or maybe do you know other reason why OP5 can't find this device?
BTW, here is an app: https://play.google.com/store/apps/...l&rdid=com.medtronic.diabetes.guardianconnect
