First it all, thank you to all of the contributors to this thread, helping the rest of us to improve this phone.

I have a question:

I've rooted it with this method: http://xdaforums.com/showthread.php?t=1886460

Then, I installed the recovery that is inside "2.5gb-data-perm-root.zip" using "mobileuncletools"

I works so far,..

Now I want to repartition..

Is it enough to flash ONLY EBR1.img file (either the one inside "2.5gb-data-perm-root.zip" or a new one patched with the values yo propose for 1G), instead of flashing ALL of the files inside "2.5gb-data-perm-root.zip" ?

I would prefer to fllash as few files as possible to reduce the risk of bricking it.

Thank you,
[Android General] llinde:
Yes, only EBR1 can be flashed, takes just a few seconds, after that you should reboot in recovery mode and format data.

o.k.

I see the information, but I don't understand hex number what to refer.

I did the math and see that it is 4096 I do not know what they are.

I installed ebr1hacked.img, I saw that the partition of the internal memory was very low so I re-flashing the ebr.img getting the results posted first.

I have no idea how to create the file ebr.img with these new values ​​that you posted to get the internal memory of 1 GB as I wrote.

When you apply this new amendment partitions become like the ones I posted above?

There is a risk of brick the phone?

If something goes wrong it is sufficient to re-flash the original ebr1 to solve?

I can ask those who are familiar with these hacks to post the file ebr.img modified to get 1 Gb of internal memory and 1,5 Gb of memory telephone ?

I believe it can be useful for everyone because there are very few 503 Mb.

It 'possible that after the terminal having trouble with speed ?

I read in an italian forum that is being testing the Jelly of this device, But there are problems with high consumption of battery. It 'a real news?

The value post previusly are not correct, because if I want to increase the internal memory to 1 Gb I must necessarily decrease the phone memory.

If the amount is to 512 more, the phone memory will be reduced by this value (512).

The correct refer is the following :

Actual

503 Mb Internal Memory

31,24 Gb Sd (micro sd 32Gb)

2,5 Gb Phone Memory

After the hack

Like this :

1024 Mb Internal Memory (+ 512 )

31,24 Gb Sd (micro sd)

2 Gb Phone Memory ( -512 )

Thanks again for the support for the benefit of all.

Hi there,

Thanks for the explanation :)

Although I have a doubt, besides the possibility to manually define the size of each partition (I still don't know how to make those calc's) is it possible to move all to the "Internal Android partition Memory"?

I mean disable the "Internal Phone memory" all together?

I'm asking this because "if" we do add an SDCard (everyone would do it for sure, I think! because 4GB are very cheap) there is no need for it.

And no more problems with two SDCard (android) devices being found and sometimes causing problems...

What do you think?

[Android General] Nixus_Maximus:
Thank you for your manual, that looks easily doable. One question: did this procedure improve signal stability? I find the fact the gps signal during car navigation is lost every 5-10 minutes more annoying than the accuracy and the duration of getting a fix (although I assume that all is interrelated).

Theoretical you could remove the second entry in the EBR and change the first one to the maximum size.

I am not an Android expert enough to know what could be the results.

I'm sure the internal SD card is gone when you do that, but maybe the OS needs to mount it somewhere, so I would not take the risk, but if somebody wants, be my guest:p

I think that when it does not work it always should be possible to reflash again, but this just is a feeling and I am not 100% certain.

Luit
[Android General] fjorger:
Thanks Luit

Thanks for answering.

Can you point out what I should change on the EBR to make such a change? I mean I will try it on my own risk...

Best regards,

---------- Post added at 12:49 PM ---------- Previous post was at 12:30 PM ----------

Hello,

I didn't had any signal instability before :(, did you? I mean with B92M original antenna?

I'm still doing tests, because I'm not very happy with the open road results:

- The "minimum" Accuracy value I got was 19m (I had 13 with the original antenna), so something isn't right!

I wonder how everyone else made the connection between the copper area (on the original antenna) to the new antenna? Solder?

I mean I used a special copper tape (glue that is supposedly conductive) no solder whatsoever.

But I suspect that little detail "not soldered connection" could lead to the problems I'm having right now, unfortunately I never had any SAT with SNR value greater than 36/38 :(

The only positive side was the "indoor" results, I didn't want to solder but I see no other way...

Regards,
[Android General] danycmoi:
I tested the new antenna Oréfie on 2 B92, the results are excellent, by rolling precision between 9 and 12 m.

In car park precision 7m.

I also added new firware / radio of 2012/11/14.

[Android General] llinde:
I would advice NOT to try.....

For the moment I just use my knowledge of standard MBR and EBR records, but there are some things here I cannot explain, an expert should do so...

I know that EBR records contain 2 partirion entries, the first describing the current partition and the second describing the next partition and link to the next EBR if any available.

EBR records describe logical partitions/drives in an extended primary partition.

When I take a look in the MBR file and in the EBR1 file I just see some things I cannot explain, for instance in the MBR the number of sectors of the extended partition is FFFF FFFF, which seems illogical to me (far too high), and also the number of sectors in the second entry of the EBR1 file is far too high.

But since it are only files that are flashed to memory, it is difficult to be sure what exactly is copied to the real MBR and EBR records.

Normally there is an EBR record for each logical partition in the extended drive, and the last EBR should have its secondary entry empty.

Since EBR1 has a filled in secondary entry there should be also a second EBR record on the system, so I think somehow the flashing process does something extra to create a second EBR record and when you just empty the second record in the EBR1 file, you might frustrate that process.

I'm curious how Veisen decided to make his hack, I looked at what he did and somehow it looks logical to me too and therefore I could change it to a 2 GB data partition and I'm sure I can change it to any other size between 512 and 2.5GB too, but since the EBR mechanism consists of chains, and we don't see the complete chain and don't know how the flash program is processing the info, I would not try to remove one of the partitions.

[Android General] spotty130:
For the ebr1 and mbr I found this in a Italian Forum, but I haven't no idea and not understand the explanation.

Is very complex for those unfamiliar with linux partition table.

Extract of the page and translate :

"... the length is formally incorrect, but because it has a

0xffcbe0df 0x341f20 + = 0xffffffffin practice means to the end ...

probably in this way is automatically manage flash of various sizes 4GB 8GB 16GB..."

For anyone who is able to understand and operate these changes for the benefit of our B92M !

Are waiting for a likely solution ebr1 improved to be tested.
[Android General] ril z:
Can you please upload all associated gps files found in /system/etc/? I accidentally messed them.
[Android General] Rumchata:
Luka, which emmc.txt file did you use to flash the system.img?
[Android General] llinde:
Thank you for the info, this explains (at least a bit) my questions about the far too high numbers.

I already tested 0.5 GB, 2.0GB and 2.5 GB data and confirm they all work.

One extra info I should add is that I dumped my original data (0.5 GB), then changed data to 2.0 GB and formatted.

At that moment data partition was indeed 2.0 GB, after that I flashed back my original data, which worked, but also my partition was back to 0.5 GB

This means dat if you want to increase your data size you should make a regular backup and not use the flash readback function...

It also means that flashing a data partition als causes the EBR to change.

What will happen when you flash an EBR1 file and a DATA.IMG file in the same session that are conflicting I don't know.

I think more testing is not necessary, all 3 EBR1 configurations I used worked without problems.

Luit
[Android General] spotty130:
Is that a possible solution for best partition to use in B92M ?

if this works we could reverse the two partitions?

Could work on our device, or is it just for the tablet?

---------- Post added at 08:06 PM ---------- Previous post was at 07:56 PM ----------

You were able to increase the internal memory to 1 Giga and phone memory at 2,0 Giga ????

Have you changed ebr1.img to get this?

You can post the file that I feel, too?

Then you can further increase the internal memory than the phone memory?

In this way you can install a lot more apps and do not have the message memory is full!

Just what I wanted to achieve.

Hi danycmoi,

Thanks,

Yes you have almost all SAT's at more than 30 SNR, that's why you get low errors (bellow 10m), did you soldered the new antenna? What material did you use on your antenna? Cooper ? Aluminum? What about their thickness?

About the new radio, where did you get it? From a Star site? How to install? I suppose being a ZIP we must load it using CWM? Right?

Hopping to hear from you soon,

Yes you are right, I'm not going to risk bricking a phone just for the sake of trying :(.

So I'm just going to follow your advice (do not touch the EBR).

And thanks for the complete explanation about the EBR records ;).

---------- Post added at 09:14 PM ---------- Previous post was at 09:02 PM ----------

Hi there.

So I can assume you are still using an unchanged antenna? I mean an original one, right?

I never had those signal losses either with the original antenna or the new one.

So you my be having an hardware problem!

I really don't know what you can do to help reducing the "loss of signal"!

You could try the new antenna type, but your warranty goes into smoke.

:(
[Android General] llinde:
No, thats not my advice, I just advice not to try to remove a partition completely, just change sizes.

Size changes work perfect, not only on this phone, but also on others.

I just increased the data partition from my son's N9776 from 500 MB to 2 GB.

Of course internal SD was lowered with 1.5 GB at the same time, leaving just between 500 and 600 MB, exactly as on our B92M phones.

Luit

---------- Post added at 11:07 PM ---------- Previous post was at 10:54 PM ----------

No, not exactly, I changed internal memory to 2 GB leaving about 580MB for internal SD card, which is also named phone memory.

Together you have between 2500 and 2600 MB available and with changing EBR1 you can freely divide memory between those.

So if you want 1 GB data you have left about 1.5GB internal SD/phone memory

I can guess how your EBR1 file looks and edit it 99.99% sure, but to be 100% sure you have to readback your own EBR1 file with the flash tool.

Personally I think this is also a good way to get some experience with the flash tool and see if drivers are installed correct.

You can use the scatter file from the first post in this topic.

As long as you use only the "Read back" tab of the flash tool I don't think you can brick your phone and when you succeed to get the EBR1 file from your phone with readback I think putting a modified file back is not that difficult too anymore.

Yes, I have the original antenna. My brother has the same phone (only 512mb instead of 1gb) and the same signal stability problem. Therefore, if you don't have the problem, it might be a software problem related to region? You are from Portugal? To all the other readers: Do you have a similar problem?

First time poster, frustrated over gps not fixing satellite

I just got this phone yesterday and i am frustrated the gps is does not work. I have spent many hours trying to figure out how to fix it. I found several fourms that talk about installing different software to fix the problem. However i have also found a french website that talks about physically adding a conducting antenna material to fix the problem. I am confused. Which one is best? I have been through page after page of fourms and don’t know what the best option is. any current advice would be helpful.

The french antenna... sorry can't post links

Dany you mentioned a new software fix that will work with existing gps antenna but its in russian?

I have the back cover open ready to scratch off and disconnect the gps antenna but only want to do that if there is so software updates i can do to get the gps working. can you help?
[Android General] danycmoi:
For the GPS I tried everything, patch, regulation...

It improves little, but is not sufficient.

The antenna Oréfie really solves the problem

Realize the copper antenna, better driver.

Even with firware of origin the antenna works perfectly.

+ FasterFix

Ideal to make the antenna : Roller self-adhesive copper with conductive adhesive

Thanks for the quick response, i tired to follow your work on the other android forurm. I used a knife to carefully scratch off the black plastic insulator where you connected your antenna. I am concerned about cutting the rest of the stock antenna off. can i just expose the antenna and use the suggested copper tape to extend the antenna?

Hello Dany,

Great values, I'm jealous LOL. Because I'm unable to lower then to a avg. of 12/13, never got a single "7" or "9" :(...

I'm puzzled, did you use that copper tape (I also use copper tape) because the tape is thin it's hard to keep it totally horizontally (the area where it sites isn't strait), what was it's shape? Oréfie design?

I'm asking because I saw (on the French forum where you post) another "bigger" antenna! You didn't use that right? They were only tests? Correct?

Finally, you did get better results by soldering it? Right?

Please advise,

Final assembly antenna orefie

Here is the photograph of assemblage and plan of l 'antenne.

It is possible to accomplish it there alluminium, but much bette copper.

Once l 'antenne installed, it is also necessary to create a gps.conf file, for it insttaller fasterfix

Then throw Ygps in mode engineer and make the fix several times, in l 'extérieur.

Thumb-index GPS test:

1/put 10 and 10

2/check Need 3D fix

Starting 3/

Thumb-index NMEA Log:

Starting

Thumb-index satellites

to wait for the 10 cycles, then to come back on thumb-index NMEA Log and apputer on STOP.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

LocationBasedService

- once thrown prove AGPS in l 'onglet that Enable A-GPS is checked well, to go down more low and to check 2 Allow ......, as on l 'image.

- In l 'onglet EPO prove that Enable EPO is checked well.

- Dan l 'onglet GPS coachman Full, then throw GPS

- Prove Fix in l 'onglet view,

- Once made Fix let make 2 - 3 minutes

In that way you created 2 file NMEA and A-GPS

Now your GPS will quickly fix and will be definite.

You can adjust the sign by cutting again lightly l 'antenne, low party, but 0,5 mm by 0,5mm.

Only 83.05mb Phone Storage after 2.5gb flash

Just did the 2.5 gb data flash. After I rebooted into android, a message came up stating that internal SD storage was broken and needing formatting. I formatted it as prompted and the phone storage is now showing as only 83.05 mb, however the total internal storage is showing as 2.46 gb. I tried to correct this by formatting the data in CWM and also tried doing a full factory reset, but the phone storage is still is only 83.05 mb after doing these steps, and if I mount the usb storage in android only 83.05 mb space is shown on the mounted usb disk. I also found the camera would not work as it said there was insufficient space on the internal SD and prompted me to use an external SD card which worked, but is obviously a concern.

I've tried searching this thread and the same issue has been raised previously, but no one has yet come forward with a solution to the problem.

Can anyone put my mind at rest regarding the storage allocations? Is 83.05 mb phone storage correct for the 2.5gb flash?

If its not correct can anyone suggest how I can repair or restore the correct disk size, or suggest how I can flash back to the original data size?

Thanks,

Italianie
