What do You think it is possible to port this rom to hammer?

all hardware is the same, it would be great to see CM on umi

Did you new replacement battery for this phone? :)
[Device Reviews and Information] Romagnolo1973:
:D ahh true. But probably without the film battery still continue working, is only a label, and so the phone is 2 grams lightweight

no i mean could we increase mAh with same size another brand battery?:rolleyes:

Here http://umidigi.com/forums/topic/batteria-umi-hammer/#post-10676 threre is a post requesting a real battery with 2250 mah or better on UMI official forum.
[Device Reviews and Information] b@dguy:
That's impossible I think. The phone really does not have enough space for a battery with the specified capacity .

To put the battery capacity of 2500 mAh at least it will be necessary to produce a new rear cover (with standard battery this will not fit ) . I do not think that the UMI is so big sales of this phone .

Are the buttons illuminated? Does it have a notification LED?
[Device Reviews and Information] s7yler:
Buttons are not illuminated, but it does have a notification LED. See the videos in post #1 it's shown there.
[Device Reviews and Information] Romagnolo1973:
impossible, the battery weight is only 29 grams and is thin, there is not enough space for a different battery, the only solution is if they made a different backcover

I've just been using Lewa rom for a day or so before going back to stock. My observations so far on Lewa -

lag between tasks/apps

Crashed a few times & could only reboot after removing battery

no dual band wifi, only 2.4ghz

easy install via TWRP, rather than Rootjoy

Appearance was good

phone reception was quite poor

Back to stock for me. Despite the negativity re: battery life, I'm finding it to be a better than average phone. Solid, well made, & I'm getting around 12+ hours on a charge however I'm not a real heavy user. Web surfing, music, games for around 30 mins as well as the usual playing around with the phone adjusting everything, new apps, remove apps & so on. It's fast enough as well. Compared to my Z7 mini, it doesn't come close, but what it offers as in bang for buck, surpasses alot of other China phones out there; however I've bought this as something to play with & with the prospect of trying different roms with relative ease makes the phone very attractive to me IMO

All the chinese battery manufactory are lying about the capacity.

Poor UMI was affected with the over looked quality control.

UMI should sue the battery factory for this.

They told me to contact my store to get a new battery.

It's unbelievable that a company like this does this kind of things. Let's hope the company comes with a good solution on a short notice. They should replace every battery IMO. Still, I guess they will just act as if their nose bleeds...
[Device Reviews and Information] Romagnolo1973:
UMI Spain and UMI Italy (but not UMI in China officially) said to us that if your Hammer usa a fake battery 1750 mAh you must contact your seller (e-commerce site where you buy it) give to him your IMEI and than they send you for free a new 2250 mAh battery.

But the original thread in the UMI Forum was deleted :confused:
[Device Reviews and Information] mesang:
There is another thread on UMi Digi where users are complaining, but UMi seems to be reluctant to respond. There is also a picture of a peeled of battery with the listed 2250mAh. Maybe it's just a specific batch that has these smaller batteries?

I'm getting one in a week or two, first thing to do is peel of this battery plastic. I'll post my findings here as well.

Sounds good, just have to wait.
[Device Reviews and Information] bigrammy:
Pretty certain etotalk was listed as an official seller during the promotion/presale of the Hammer and probably the reason why they were affected by this scam/mistake as Etotalk were one of the first to receive and ship the Hammer :confused:

Looks like they will be one of the first for the GMAX too :confused: http://www.etotalk.com/products_img/2015/eMax_Activity/Home/

It all makes no difference anyway as long as my phone is a genuine Umi Hammer which I am 100% sure it is then Umi should rectify the problem whether it be via the seller or directly.

If i use rootjoy is it ok to upgrade the firmware ? Via the new os like flyos or miui ?

With the new battery:

About 1 hour more in on-screen time and better battery score.
[Device Reviews and Information] mumse1:
Correct me if iam thinking about it the wrong way here....but:

Old battery 1750mha vs new battery 2250mha = ~29% better capacity.

Old battery = ~3,4h on-screen time vs New battery = ~4.8h on-screen time = ~40% increased screen time.

ill say thats a pretty big diffrence between old and new battery :)

ill think iam gonna let my order @ geekbuying stay as is. I think the battery will be enough as my wife is not a heavy user of her phone.

Thank you for testing.

To all potential Hammer buyers, I have had the phone and tested it for a week now with the so called "real" 2250 mAh battery. I'm doing a Geekbench 3 screen on (50% intensity, all radios on except BT) battery test now on it and I will be back with my thoughts about the phone later today CET. I have screen dumps of all tests also (Geekbench, AnTuTuX, GPS Test, Epic Citadel and so on) if someone wants them, but basically they just confirm what [MENTION=2105197]s7yler[/MENTION] already reported here so nicely.

I'm really thinking about buying an Hammer since I broke my Jiayu S3 a few days ago. Is the battery enough? I'm mostly just texting and listening to spotify, so no heavy using, always had like 60% left on my S3 at the end of the day.

Will the Hammer's battery be enough or should I look at something else?

The battery in the hammer is definitely enough for your use if you charge it every night and if you usually have ~60% left in the S3 at the end of the day. (See my report later in this thread)

Off topic: The 4G covers 99% of the population here on B7, 2600 MHz (cities/towns) and B20, 800 MHz (rural areas) and since last year also B3, 1800 MHz, from each one of the 3 networks here. I get 60 Mb/s with the Hammer downstream where I live.

HELP!!

Hello,

I tried to make the Update to 5.1.

I did everything as it is written in UMI Forum.

The flash with ,,Firware Update" over SP Flash Tool was sucessfull (green circle) ....BUT when i start the Phone there is just a Black Screen?!?!

Then i flashed back to Official 4.4 from NeedRom and the Phone starts normally...BUT i have a problem with the SIM cards...now the Phone wont connect to the Mobile Services :(

Can anybody Help ME PLS ??

THX
[Device Reviews and Information] s7yler:
Actually I also got a black screen the first time I tried the 5.1 ROM. But it is because you are doing something wrong, either you do not follow the steps 100% or you do not use latest SP Flash Tool.

Important is that you USE SP_Flash_Tool_Windows_v5.1516.00 and also that you hold VOL UP button down when you connect the phone.

Also very important that you do the wipe in the Recovery afterwards.

Install ROM: (everything will be deleted so make backup first!)

- Unpack FlashTools SP_Flash_Tool_Windows_v5.1516.00.zip, and Click on Flash_tool.exe

- Select the MT6752_Android_scatter.txt in ROM directory

- Wait file to be added into Flash Tool

- Change "Download Only" to "Firmware Upgrade" in SP Flash Tool

- Turn off your phone. (do not have it connected to the PC yet)

- Press the green "Download" button in SP Flash Tool

- Now connect your phone into the computer via USB data cable, while you hold VOL UP button down

- The process will start (let the button go) and a red progress bar will appear after color purple, yellow.

- And green circles display – finish !

- You can now safely disconnect your phone and turn it on.

Now we go to the Recovery.

- Hold down VOL up and Power button

- After the logo appears, let go of the buttons!

- You should now be in the Recovery (you see a green Droid laying down)

- Press the Power button once, and the Recovery menu should appear.

- Use VOL down button to go down the menu, to wipe cache and press Powerbutton to confirm.

- After that also Wipe Data Factory/Reset. (You will now delete everything on the phone!)

- Go back and reboot the phone, done!

PS. if it still doesn't work, then you may have one of the engineering samples that are not compatible. Do you get lines on the screen?
[Galaxy S 4 Active Q&A, Help & Troubleshooting] champ76:
Hello all,

I have searched hard for a solution, with no luck.

S4 ATT Active, SGH I537 does not boot past ATT splash screen.

Deleted lots of bloatware. Apparently one or some deletions were not so trivial. (If the damn bus hadnt been so late, none of this woulda happened...)

Was VERY CAUTIOUS. The file "my.att.account" looked harmless, but that is the only culprit I can think of.

Phone will not complete boot process. ATT splash screen appears, blue led blanks, ATT logo completes animation, then screen stays on the ATT spalsh.

Booting into recovery mode, ADB (on Ubuntu) recognizes device but declares it offline.

Starting "apply update from adb", adb declares the device as "sideload usb:2-5"

Because of the glimmer of communication with ADB, I'm looking for the possibility of rescuing some files from the internal mem, before doing a factory reset.

Have also tried KIES on WIN8 but win (and KIES) dont see the device at all.

Thanks,

jd
